    Full Text Available Este trabalho estuda a viabilidade de utilização de resíduos de materiais cerâmicos como agentes de adsorção de corantes utilizados em indústrias têxteis. Resíduos de materiais cerâmicos, oriundos de quebras de tijolos, azulejos e pisos foram selecionados, triturados e moídos a uma granulometria adequada, o que possibilitou o estudo da influência do tipo de material cerâmico (resíduo e da sua granulometria sobre a adsorção do corante azul de metileno. Os resíduos cerâmicos foram separados em três diferentes granulometrias, fina (0,15 mm < Dfino< 0,30 mm, média (0,30 mm < Dmédio< 1,18 mm e grossa (1,18 mm corante azul de metileno presente na amostra ensaiada. No entanto, os resultados também mostram que a absorção de água do material cerâmico pode não ser somente o fator que influencia na adsorção do corante.

    Full Text Available Este trabalho teve como objetivo empregar materiais alternativos, puros e/ou modificados com 5 ou 10% (m/m de  pentóxido de nióbio (Nb2O5, em processos de remoção de azul de metileno (AM. Entre os materiais alternativos foram utilizadas argila sanitária, argila de resíduo industrial, rochas sedimentares e cinzas de casca de arroz obtida pela queima a 350oC. Estes sólidos foram caracterizados pelas técnicas de difração de raios- X (DRX e espectroscopia na região do infravermelho (FTIR. Os testes de remoção de AM foram realizados em frascos de 125 mL, sob agitação constante, contendo 100 mL de solução de AM (100mg/L a 2000mg/L e adsorvente (0,1 a 0,6g, sob uma mesa agitadora a 200 rpm, em temperatura ambiente. A quantificação da remoção de AM foi realizada com auxílio de um espectrofotômetro UV-Vis da Varian (Cary 50, coletando 2 mL de amostra nos períodos de 2 à 1440 min. Dados de DRX evidenciaram uma mistura de argilominerais nos sólidos baseados em argilas. Nos ensaios de adsorção os materiais demonstraram eficiência para a remoção do corante, com destaque aqueles modificados com 10% de Nb2O5 exibindo 95% de remoção, no tempo de 120min, em solução de pH de ~6,5.

    Full Text Available A biopsia de linfonodo sentinela (LS é cada vez mais utilizada para a determinação do estadiamento clínico tumoral. O acometimento de linfonodos em animais com doença oncológica possui forte valor prognóstico no tumor da glândula mamária. Em medicina veterinária faltam diretrizes bem estabelecidas para a avaliação do LS. O objetivo deste estudo foi avaliar a eficácia do corante azul de metileno a 2% na identificação do linfonodo axilar em cadelas com lesões mamárias. Para tanto, foram utilizadas 101 cadelas, portadoras de lesões mamárias, submetidas à mastectomia radical unilateral ou bilateral. Antes do início da cirurgia, aplicou-se, por via intradérmica, na área ao redor da mama torácica cranial, solução de azul de metileno a 2% estéril. O corante foi eficaz na identificação do linfonodo axilar em 76,27% das cadeias mamárias. Obtiveram-se estruturas coradas em azul, semelhantes a linfonodos em 78,81% dos casos. Dessas estruturas, 96,77% foram confirmadas ao exame histopatológico como linfonodos. Dada a importância prognóstica do comprometimento de linfonodos em alguns tumores, a avaliação do LS deve ser incorporada à rotina clínica, de modo a permitir um estadiamento mais preciso das cadelas com neoplasia mamária.

Este trabalho teve por objetivo investigar a eficiência da remoção de corante artificial FD&C azul no 2 Indigotina, com uso do fungo de degradação branca Trametes versicolor em combinação com a filtração lenta. Para a realização dos trabalhos, foram instalados dois protótipos de filtros lentos denominados FL-A e FL-B - no sobrenadante do filtro FL-A foi inoculado o referido fungo, e o filtro FL-B foi utilizado como controle (sem inoculação do microrganismo. O melhor percentual de remoção do corante pelo fungo Trametes versicolor em combinação com a filtração lenta foi de 44,74% 24 horas após a atividade máxima registrada de lacase. Os resultados mostraram que a filtração lenta combinada com o tratamento com o fungo T. versicolor não apresenta grande potencial para remoção de cor em 21 dias de tratamento, visto que os produtos microbianos gerados interferem no processo de filtração, diminuindo a eficiência do processo físico. Entretanto, restringindo o tempo de tratamento a 24 horas após a atividade enzimática máxima, o tratamento combinado apresentou boa eficiência.

    Full Text Available A contaminação dos recursos hídricos é um dos maiores problemas ambientais da atualidade. Dentre as várias fontes poluidoras, destacam-se as indústrias têxteis, por serem fontes geradoras de grandes volumes de efluentes, muitas vezes tratados de maneira ineficiente. A principal causa do grande impacto ambiental decorrente deste descarte é a presença dos corantes, tais como os compostos do tipo azo, que podem gerar subprodutos de caráter carcinogênico e/ou mutagênico, ou como os de base antraquinona, que são muito resistentes à degradação natural e portanto persistem no efluente por um longo tempo. O objetivo do presente trabalho consiste na utilização de processos foto-Fenton assistidos por luz artificial e solar, utilizando ferro imobilizado em esferas de quitosana reticulada com glutaraldeído, para promover a degradação do corante reativo Azul QR-19, de base antraquinona, em solução aquosa. As esferas obtidas apresentaram tamanho regular com diâmetro de 4,0 mm. Os resultados demonstraram 90% de descoloração do sistema em 180minutos e redução de 60% do teor de carbono orgânico total (COT, para o sistema foto-Fenton utilizando luz artificial. Para o sistema fotoassistido com luz solar, a descoloração foi integralmente obtida em 120 minutos com 70% de redução do teor de COT. Foi observado que o ferro permaneceu na matriz após o tratamento, possibilitando sua reutilização.The contamination of water resources is one of the greatest environmental problems today. Among the polluting sources are the textile industries due to the production of large volumes of effluent, often treated inefficiently. The main reason for the environmental impact of the rejected materials is the presence of dyes such as azo reactive compounds that can generate by-products with carcinogenic and mutagenic effects. They may also include anthraquinone type compounds, which are highly resistant to degradation and persist in the effluent for a

    Full Text Available Remazol Brilliant Blue R (RBBR dye was used as substrate to evaluate ligninolytic activity in 125 basidiomycetous fungi isolated from tropical ecosystems. The extracellular RBBR decolorizing activity produced when selected fungi were grown in solid media and in soil contaminated with organochlorines was also evaluated. A total of 106 fungi decolorized the RBBR during the growth in malt extract agar (MEA, 2%; 96 fungi showed a mycelia growth and decolorization activity stronger than the P. chrysosporium used as reference. Extracellular extracts of 35 selected fungi grown on solid medium with sugar cane bagasse (BGS were evaluated for RBBR decolorization and peroxidase activity. All fungi showed peroxidase activities, but 5 of those were unable to decolorize the RBBR. Different patterns of ligninolytic enzymes were detected in 12 fungi extracts. Mn-dependent peroxidase (MnP was produced by Peniophora cinerea, Psilocybe castanella, three strains of Trametes villosa, T. versicolor, Melanoporia nigra and Trichaptum byssogenum. All 12 fungi had laccase activity. Trogia buccinalis showed the highest RBBR decolorization and did not produce MnP activity. RBBR decolorization without MnP production was also observed for three strains of Lentinum tested. Higher levels of peroxidase and laccase cannot be related to high RBBR decolorization. RBBR decolorization by extracellular extract was also detected during the growth of P. castanella, L. crinitus, P. cinerea and two strains of T. Villosa in pentachlorophenol- and hexachlorobenzene-contaminated soils. These fungi showed higher RBBR decolorization when grown in the presence of organochlorine compounds than when in non contaminated soil.O corante azul brilhante Remazol R (RBBR foi usado como substrato para avaliar 125 fungos basidiomicetos isolados de ecossistemas tropicais brasileiros quanto a atividade ligninolítica.

    Full Text Available O presente trabalho avaliou a capacidade de adsorção do corante azul de metileno nos resíduos da palha de milho e da bainha do palmito pupunha in natura. A caracterização dos resíduos foi determinada utilizando-se a microscopia eletrônica de varredura e espectroscopia na região do infravermelho a qual indicou a presença de grupos carboxílicos, hidroxila e carbonila. O tempo necessário para que o sistema atingisse o equilíbrio para ambos os resíduos foi de 240 min, seguindo uma cinética descrita pelo modelo de pseudo-segunda ordem. A capacidade máxima de adsorção foi de 102,8 mg g-1 para o resíduo da palha de milho, seguindo o modelo de isoterma de Langmuir e 50,9 mg g-1 para o resíduo de palmito pupunha, sendo que o modelo que melhor se ajusta foi Freundlich. Desta forma, esses resíduos são promissores para a adsorção do corante azul de metileno em efluentes.

    2016-02-01

    Full Text Available Lentinula edodes belongs to the group of fungi known as ligninolytic fungi, due to its ability to degrade the aromatic structure of the lignin. Textile dyes also have aromatic structure, and after microbial degradation, some of them can be transformed into toxic compounds, when compared to the original structure, representing risk to environment and human health. Therefore, the potential of the fungus L. edodes INCQS 40220 to decolorize and to detoxify reactive red 198 (azo dye, reactive blue 214 (azo dye and reactive blue 21 (cooper phthalocyanine dye in a mixture (MXD, was evaluated. After 14 days of incubation, total decolorization in liquid media was obtained. The fungal treatment of MXD did not present toxic effects towards blood human cells. The genotoxicity of MXD, assessed by Comet assay, was efficiently reduced to 61% and in the Ames test presented negative response for mutagenicity for Salmonella enterica serovar Typhimurium TA97, TA98, TA100 and TA102 strains. The results indicated L. edodes INCQS 40220 efficiency on decolorization and genotoxicity reduction of a mixture of different dyes. Therefore, based on these results, obtained under laboratory conditions, L. edodes INCQS 40220 has potential for textile effluent treatment. ============================================= Lentinula edodes pertence ao grupo de fungos conhecidos como fungos ligninolíticos, devido a sua habilidade de degradar estruturas aromáticas da lignina. Corantes têxteis também possuem estruturas aromáticas e, após a degradação microbiana, alguns destes corantes podem ser transformados em compostos tóxicos quando comparados à estrutura original, representando risco à saúde ambiental e humana. Portanto, o potencial do fungo L. edodes INCQS 40220 para descolorir e detoxificar a mistura de vermelho reativo 198 (corante azo, azul reativo 214 (corante azo e azul reativo 21 (corante ftalocianina de cobre foi avaliada (MXD.

    Full Text Available RESUMOO processo de oxidação avançada do tipo reação Fenton (Fe2+/H2O2 foi estudado neste trabalho para descoloração de dois efluentes sintéticos, contendo os corantes Azul de Metileno (AM e Rodamina B (RB. Experimentalmente, soluções em concentração de 10 mg L-1 dos corantes foram submetidas a diferentes dosagens de agente oxidante (H2O2 e catalisador (Fe2+ em uma temperatura de 27 °C e pH 3. Os resultados obtidos apresentaram altos níveis de remoção de cor, com eficiência da ordem de 96% para o AM e 86% no RB. Os dados mostraram bom ajuste ao modelo cinético. O monitoramento do espectro de absorção dos corantes mostrou uma diminuição da amplitude dos picos relacionados aos grupos cromóforos em ambos compostos, corroborando com os níveis de eficiência alcançados. A análise de remoção de matéria orgânica em termos de Demanda Química de Oxigênio (DQO não acompanhou a mesma taxa de decréscimo de descoloração, obtendo-se reduções de 40,9% para o AM e 25,5% para o RB.

Based on midpoint potential and separation of cathodic and anodic peaks (ΔE, it was not observed interaction of different eletrolytes with the cationic dyes by an ion exchange reaction and, as a consequence, absence of leaching of cationic dyes to the solution phase. The kinetics of electron transfer on the surface electrode was not sufficiently fast showing a fairly resistence of carbon nanotube paste modified with the mediators. The midpoint potential and ΔE also were insentive to the pH range (4-8, confirming the protective effect of carbon nanotubes matrix, owing to strong interaction of between the latter and the nitrogen of nitrogen of cationic dyes with carbon nanotube matrix, minimizing the proton interaction under cationic dye. This result is very important for sensor/biosensor preparation, because the eletrooxidation behavior of the analyte will be only affected by its formal potencial shifting. Carbon nanotubes proved to be an efficient solid matrix for the adsorption of mediator electron in comparison to the electrochemical behavior of free cationic dyes in solution phase.O presente trabalho descreve o comportamento eletroquímico de azul de metileno e azul de toluidina como mediadores de elétrons adsorvidos em pasta de nanotubo de carbono multiparede. Com base no potencial médio e na separação de pico catódico e anódico (ΔE, não foi observada interação de diferentes eletrólitos com os corantes catiônicos por meio de reação de troca iônica e, como consequência, ausência de lixiviação dos corantes para solução. A cinética de transferência de elétron na superfície do eletrodo não foi suficientemente rápida, mostrando razoável resistência da pasta de nanotubo de carbono modificada com os mediadores. O potencial médio e ΔE também foram insens

    RESUMO: Dentre os produtos do metabolismo secundário vegetal, os pigmentos ou corantes têm despertado especial interesse, pela sua importância na indústria de alimentos. No caso de oferecerem menos riscos à saúde humana, poderão vir a substituir os corantes sintéticos, principalmente os que são questionados quanto a possíveis reações alérgicas. Desse modo, testaram-se os corantes da beterraba e da batata-doce roxa em células meristemáticas da raízes de Allium cepa, a fim de verificar possíveis alterações no processo de divisão celular. Os resultados obtidos demonstraram citototoxidade induzida pelo corante de beterraba que foi, em seguida, testado em células da medula óssea de Rattus norvergicus. Em todos os parâmetros analisados não se detectaram alterações induzidas por esse corante nos animais tratados quando esses foram comparados aos seus respectivos controles. Em vista dos resultados obtidos, parece viável o uso do corante da beterraba como aditivo alimentar, apesar de não terem sido consideradas as vantagens técnicas e econômicas relativas ao seu emprego. PALAVRAS-CHAVE: Corantes vegetais; antocianinas; betacianinas; genotoxidade.

    Full Text Available RACIONAL: O esôfago de Barrett é uma condição na qual a mucosa escamosa esofágica é substituída por metaplasia intestinal especializada, que predispõe o paciente ao desenvolvimento de adenocarcinoma esofágico. Este é precedido por displasia e carcinoma precoce; o rastreamento dessas lesões faz-se através de endoscopias digestivas periódicas com biopsias randomizadas. A incidência aumentada desse, tem despertado interesse no desenvolvimento de novas técnicas endoscópicas, como a cromoendoscopia com azul de metileno, para melhorar a identificação do esôfago de Barrett e suas complicações. OBJETIVO: Determinar se as biopsias dirigidas pela cromoendoscopia com azul de metileno oferecem vantagem em relação ao método convencional na detecção do esôfago de Barrett. MATERIAL E MÉTODO: Estudaram-se 45 pacientes com diagnóstico prévio de esôfago de Barrett, todos submetidos a dois exames de endoscopia digestiva alta com biopsias, em intervalo de 4 semanas, um convencional e outro com aplicação do corante, no período entre abril e outubro de 2002. RESULTADOS: Os resultados histológicos das biopsias de todos os exames foram comparados. Observou-se sensibilidade de 62,5%, especificidade de 15,4%, valor preditivo positivo de 57,7% e valor preditivo negativo de 18,2%. Não houve diferença significativa quanto ao número de biopsias. O tempo de duração da técnica de cromoendoscopia foi significativamente maior quando comparado ao da técnica convencional. CONCLUSÃO: Não se observou vantagem na utilização da cromoendoscopia em relação à técnica randomizada no diagnóstico do esôfago de Barrett.

    Full Text Available The objective of this study was to evaluate the influence of calcium hydroxide in intracanal dressing on the ability of the dyes rhodamine B and methylene blue to label the dentine. Forty extracted human mandibular premolars had their canals instrumented and were divided into four groups: in two groups, the canals were filled with a calcium hydroxide paste and the others remained in distilled water. After 15 days, in two groups (with and without dressing, the canals were obturated with sealer containing methylene blue, whereas the others contained rhodamine B. For analysis, the roots were transversally sectioned in their cervical, medium and apical thirds, and the labeling was analyzed. The Mann-Whitney test showed statistically significant difference between the dressing/methylene blue group and the others. Based on these results, it was concluded that calcium hydroxide in intracanal dressing negatively interferes with the labeling ability of methylene blue.Objetivou-se avaliar a influência do curativo intracanal de hidróxido de cálcio sobre a capacidade dos corantes azul de metileno e rhodamine B de marcar a dentina, quando incorporados à massa obturadora, no momento da espatulação.

    Agave plants utilize crassulacean acid metabolism (CAM) for CO(2) fixation. Fructans are the principal photosynthetic products generated by agave plants. These carbohydrates are fructose-bound polymers frequently with a single glucose moiety. Agave tequilana Weber var. azul is an economically important CAM species not only because it is the sole plant allowed for tequila production but because it is a potential source of prebiotics. Because of the large amounts of carbohydrates in A. tequilana, in this study the molecular structures of its fructans were determined by fructan derivatization for linkage analysis coupled with gas chromatography-mass spectrometry (GC-MS), nuclear magnetic resonance (NMR), and matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF-MS). Fructans were extracted from 8-year-old A. tequilana plants. The linkage types present in fructans from A. tequilana were determined by permethylation followed by reductive cleavage, acetylation, and finally GC-MS analysis. Analysis of the degree of polymerization (DP) estimated by (1)H NMR integration and (13)C NMR and confirmed by MALDI-TOF-MS showed a wide DP ranging from 3 to 29 units. All of the analyses performed demonstrated that fructans from A. tequilana consist of a complex mixture of fructooligosaccharides containing principally beta(2 --> 1) linkages, but also beta(2 --> 6) and branch moieties were observed. Finally, it can be stated that fructans from A. tequilana Weber var. azul are not an inulin type as previously thought.

    Agave tequilana Weber var. azul, is the only one variety permitted by federal law in México to be used for tequila production which is the most popular contemporary alcoholic beverage made from agave and recognized worldwide. Despite the economic, genetic, and ornamental value of the plant, it has not been subjected to detailed cytogenetic research, which could lead to a better understanding of its reproduction for future genetic improvement. The objective of this work was to study the meiotic behavior in pollen mother cells and its implications on the pollen viability in Agave tequilana Weber var. azul. The analysis of Pollen Mother Cells in anaphase I (A-I) showed 82.56% of cells with a normal anaphase and, 17.44% with an irregular anaphase. In which 5.28% corresponded to cells with side arm bridges (SAB); 3.68% cells with one bridge and one fragment; 2.58% of irregular anaphase showed cells with one or two lagging chromosomes and 2.95% showed one acentric fragment; cells with two bridges and cells with two bridges and one acentric fragment were observed in frequencies of 1.60% and 1.35% respectively. In anaphase II some cells showed bridges and fragments too. Aberrant A-I cells had many shrunken or empty pollen grains (42.00%) and 58.00 % viable pollen. The observed meiotic irregularities suggest that structural chromosome aberrations have occurred, such as heterozygous inversions, sister chromatid exchanges, deletions and duplications which in turn are reflected in a low pollen viability.

Foram realizadas leituras periódicas do espectro de absorção noscomprimentos de onda entre 700 e 190 nm para verificar alterações químicas nos corantes estudados. No caso de refrigerantes em embalagem de PET verificou-se a relação entre luz incidente e luz transmitida pela embalagem, estabelecendo a sua função como filtro adeterminadas radiações luminosas. Os dados obtidos com os corantes nas amostras de refrigerantes foram comparados com os dados obtidos com os corantes em solução. Constatou-se que em pH mais ácido há um aumento na velocidade de degradação dos corantes, do mesmo modo que na presença de citratos ou ascorbatos. A presença de benzoatos retarda o processo de degradação dos corantes.The stability of synthetic food dyes tartrazine and yellow sunset was studied in relation to the intensity of radiation in the ultraviolet and visible spectra, as well as the influence of the pH and others additives normally presents in some products. Periodic scanning of theabsorption spectrum was accomplished in the wavelengths between 700 nm and 190 nm to verify alterations in this dyes. In the case of soft drinks in PET packing, the relation was verified between incident light and light transmitted by the packing, establishing its function as filter to radiation. The data obtained with the dyes in the samples of soft drinks were compared with standard dyes solutions. In acid media, citrate and ascorbate presence, a major degradation process occurs.

    2016-08-01

    The number of patents is not so important as the market value. The market value is especially important for licensing of patents, make-or-buy decisions for technology procurement, corporate finance. Patents can be used as collateral for financing. Patents and credit approvals: without patents only 46% and with patents 54%. The value share of knowledge-based components to industrial products already reached 50% and it is still rising. OECD called these developments under the slogan "knowledge economy”. German Norm-DIN 77100 provides a working method for monetary evaluation of a patent. The value of a patent arises from its use. A patent can be used to protect or to earn licensing revenues. An evaluation expertise is required in areas, such as marketing, finance, R & D and strategic planning. As an indicator of the value of a patent is often used the number of citations. The number of a patent citation refers to its meaning and value. Other indicators would be: size of the patent family, validity of the patent, result of objections against patent application, number and quality of claims. The analysis of 9.000 patents resulted that only 7.2% worth over 10 million euro and 68% below 1 million euro. The cost method: it is considered the cost that would be incurred for the development and patenting of a similar invention. The market method: are used the prices that have been achieved in comparable with recently transactions. The Income method: the potential reward is measured, which can arise from a patent. The evaluation will be in the following areas: legal status, technology, market conditions, finance and strategy. Each question relates to a different parameter of a value.

  6. Patents and nanomedicine.

    2007-06-01

    Big pharma's business model, which relies on a few blockbusters to generate profits, is clearly broken. Patent expiration on numerous blockbusters in recent years is already altering the drug landscape. Drug companies are also facing other challenges that necessitate development and implementation of novel R&D strategies, including those that focus on nanotechnology and miniaturization. Clearly, there is enormous excitement and expectation regarding nanomedicine's potential impact. However, securing valid and defensible patent protection will be critical. Although early forecasts for nanomedicine commercialization are encouraging, there are numerous bottlenecks as well. One of the major hurdles is an emerging thicket of patent claims, resulting primarily from patent proliferation as well as continued issuance of surprisingly broad patents by the US Patent and Trademark Office (PTO). Adding to this confusion is the fact that the US National Nanotechnology Initiative's widely cited definition of nanotechnology is inaccurate and irrelevant from a nanomedicine perspective. It is also the cause of the inadequate patent classification system that was recently unveiled by the PTO. All of this is creating a chaotic, tangled patent landscape in various sectors of nanomedicine where the competing players are unsure of the validity and enforceability of numerous issued patents. If this trend continues, it could stifle competition and limit access to some inventions. Therefore, reforms are urgently needed at the PTO to address problems ranging from poor patent quality and questionable examination practices to inadequate search capabilities, rising attrition, poor employee morale and a skyrocketing patent application backlog. Only a robust patent system will stimulate the development of commercially viable nanomedicine products that can drastically improve a patient's quality of life and reduce healthcare costs.

    Full Text Available The omnipresent, unstoppable increase in digital data has led to a greater understanding of the importance of data privacy. Different approaches are used to implement data privacy. The goal of this paper is to develop a data anonymization patent landscape, by determining the following: (i the trend in data anonymization patenting, (ii the type of technical content protected in data anonymization, (iii the organizations and countries most active in patenting data anonymization know-how; and (iv the topics emerging most often in patent titles. Patents from the PatSeer database relating to data anonymization from 2001 to 2015 were analyzed. We used the longitudinal approach in combination with text mining techniques to develop a data anonymization patent landscape. The results indicated the following. The number of single patent families is growing with a high increase after 2010, thus indicating a positive trend in the area of patenting data anonymization solutions. The majority of patenting activities relate to the G Physics section. Organizations from the USA and Japan assigned the majority of patents related to data anonymization. The results of text mining indicate that the most often used word in titles of data anonymization patents are “anonym*, “method”, “data” and “system”. Several additional words that indicated the most frequent topics related to data anonymization were: “equipment”, “software”, “protection”, “identification”, or “encryption”, and specific topics such as “community”, “medical”, or “service”.

    Full Text Available Abstract Agave tequilana Weber azul variety is a valuable source of fructans. In this study, a response surface methodology was employed to optimize the extraction yield of fructans from agave pines. A Box Behnken factorial design was applied to evaluate the effects of several conditions such as extraction temperature, water raw material ratio and extraction time on extraction yield. Under the optimum extraction conditions (extraction temperature of 79.1 °C, water raw material ratio of 5.13 mL/g, and extraction time of 1.48 h fructans extraction yield was 83.12%. The chromatographic profile of the agave crude extract presented four peaks, out of which fructans were the most preponderant (~87%. The obtained results suggest that the response surface methodology is adequate to optimize fructans extraction from Agave tequilana Weber azul variety.

    There is a need for investigators, legislators, and business leaders to understand the magnitude of innovation and discovery in the field of environmentally conscious technologies (ECTs). Knowledge of the "big picture" is important to providing a national and global account of actual environmental stewardship over the last twenty-five years. A recitation of the Environmental Protection Agency (EPA) supported Acts which have been enacted into law reveals one facet of the multifaceted dynamic of environmental consciousness. The popular discussion and debate, as well as partisan lobbying, which created the political forces leading to environmentally conscious legislation is another facet. A third facet is the corporate response to the threats and opportunities predicted by CEO"s and others through environmental scanning. This paper examines changes in environmentally conscious inventive effort by comparing data from United States Patents issued from 1976 through 2003. Patents are useful tool for measuring technological innovation because they are publicly available records of innovative activity. Although not all inventions result in patent applications, the monopoly rights granted on the invention give the inventor a strong incentive to obtain patents on any viable product or process. Among the results, we found a significant increase in patents relating to environmentally conscious products and processes during the period in question. Specifically, a dramatic increase in patent activity was seen for the decade of the 1990"s. Surprisingly, the patenting rate from 2000 to 2003 seems to have stabilized. Additionally public discussion of ECTs appears to have a positive impact on patent filings.

  14. Searching bioremediation patents through Cooperative Patent Classification (CPC).

    Science.gov (United States)

    Prasad, Rajendra

    2016-03-01

    Patent classification systems have traditionally evolved independently at each patent jurisdiction to classify patents handled by their examiners to be able to search previous patents while dealing with new patent applications. As patent databases maintained by them went online for free access to public as also for global search of prior art by examiners, the need arose for a common platform and uniform structure of patent databases. The diversity of different classification, however, posed problems of integrating and searching relevant patents across patent jurisdictions. To address this problem of comparability of data from different sources and searching patents, WIPO in the recent past developed what is known as International Patent Classification (IPC) system which most countries readily adopted to code their patents with IPC codes along with their own codes. The Cooperative Patent Classification (CPC) is the latest patent classification system based on IPC/European Classification (ECLA) system, developed by the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO) which is likely to become a global standard. This paper discusses this new classification system with reference to patents on bioremediation.

    Full Text Available It is widely recognized that the pharmaceutical industry faces serious financial challenges. Large numbers of blockbuster drugs are losing patent protection and going generic. The pipeline of new drugs is too sparse to fill the gap and generate a platform for future growth. Moreover, many of the new products are biologics with much narrower target patient populations and comparatively higher prices relative to traditional pharmaceuticals. So now the time has come for pharmaceutical scientists to have a better understanding of patent fundamentals. This need is illustrated by analyses of key scientific and legal issues that arose during recent patent infringement cases involving Prozac, Prilosec, and Buspar. Facing this scenario, the pharmaceutical industry has moved to accelerate drug development process and to adopt at the same time different strategies to extend the life time of the patent monopoly to provide the economic incentives and utilizing it for drug discovery and development. This review covers the need of patent protection and various strategies to extend the patent.

    2017-01-01

    Full Text Available Evaluating the values of patents is critical for both managers and investors. Patent maintenance time is an ideal proxy indicator for evaluating commercial patent value. This study investigated the survival rates of patents in the semiconductor industry by using a survival analysis and incorporated a predictive model for patent maintenance times. The technical characteristics of the patents, the assignee factors, and the statuses of the patents were used as the predictive factors for patent maintenance time. The results revealed a small entity size and the number of assignees are the risk factors that increase the likelihood of the maintenance time of a patent decreasing. The litigation status of a patent and the number of its international patent classifications, claims, forward citations, and assignments were determined to be the protection factors that raise the likelihood of its maintenance time extending. Additionally, substantial differences were noted between small entities and nonsmall entities and between being litigated and not in their effects on the survival rates of patents. This study examined the factors that affect the survival rates of patents and provides a reference for the managers and investors of intellectual property rights to use when assessing technical and commercial patent values.

  10. Patenting human genes: Chinese academic articles' portrayal of gene patents.

    Science.gov (United States)

    Du, Li

    2018-04-24

    The patenting of human genes has been the subject of debate for decades. While China has gradually come to play an important role in the global genomics-based testing and treatment market, little is known about Chinese scholars' perspectives on patent protection for human genes. A content analysis of academic literature was conducted to identify Chinese scholars' concerns regarding gene patents, including benefits and risks of patenting human genes, attitudes that researchers hold towards gene patenting, and any legal and policy recommendations offered for the gene patent regime in China. 57.2% of articles were written by law professors, but scholars from health sciences, liberal arts, and ethics also participated in discussions on gene patent issues. While discussions of benefits and risks were relatively balanced in the articles, 63.5% of the articles favored gene patenting in general and, of the articles (n = 41) that explored gene patents in the Chinese context, 90.2% supported patent protections for human genes in China. The patentability of human genes was discussed in 33 articles, and 75.8% of these articles reached the conclusion that human genes are patentable. Chinese scholars view the patent regime as an important legal tool to protect the interests of inventors and inventions as well as the genetic resources of China. As such, many scholars support a gene patent system in China. These attitudes towards gene patents remain unchanged following the court ruling in the Myriad case in 2013, but arguments have been raised about the scope of gene patents, in particular that the increasing numbers of gene patents may negatively impact public health in China.

  11. Are biosimilars patentable?

    Science.gov (United States)

    Rolfe, Damian; Parker, Jayson; Morgan, Max

    2016-08-01

    This paper explores whether, and under what circumstances, a biosimilar approved in the United States under the Biologics Price Competition and Innovation Act (hereafter 'BPCIA') can be patented. The possibility that a biosimilar product could have meaningful patent protection arises from specific requirements for biosimilarity under the BPCIA, which account for the fact that manufacturing processes of biologics are inherently imprecise. The requirements for biosimilar approval may provide sufficient leeway to a biosimilar applicant to patent structural or formulation differences that provide non-clinical but business-relevant advantages over the reference molecule, such as improved shelf-life or ease of manufacture, without compromising clinical biosimilarity. Examination of the BPCIA and related Acts, Food and Drug Administration (FDA) guidance papers, case law, patent database searching, and relevant scholarly articles. Legislative and regulatory requirements for the approval of a biosimilar under the BPCIA are focused on clinical results and allow a degree of leeway for differences to exist between a biosimilar's structure and non-clinical components and those of the biosimilar's reference molecule. This leeway can be exploited to provide the biosimilar with potentially patentable business-relevant advantages over its reference product while maintaining clinical biosimilarity to the reference product.

  12. Generation of Maillard compounds from inulin during the thermal processing of Agave tequilana Weber Var. azul.

    Mancilla-Margalli, Norma A; López, Mercedes G

    2002-02-13

    During the cooking process of Agave tequilana Weber var. azul to produce tequila, besides the hydrolysis of inulin to generate fermentable sugars, many volatiles, mainly Maillard compounds, are produced, most of which may have a significant impact on the overall flavor of tequila. Exudates (agave juice) from a tequila company were collected periodically, and color, Brix, fructose concentration, and reducing sugars were determined as inulin breakdown took place. Maillard compounds were obtained by extraction with CH(2)Cl(2), and the extracts were analyzed by GC-MS. Increments in color, Brix, and reducing sugars were observed as a function of time, but a decrease in fructose concentration was found. Many Maillard compounds were identified in the exudates, including furans, pyrans, aldehydes, and nitrogen and sulfur compounds. The most abundant Maillard compounds were methyl-2-furoate, 2,3-dihydroxy-3,5-dihydro-6-methyl-4(H)-pyran-4-one, and 5-(hydroxymethyl)furfural. In addition, a series of short- and long-chain fatty acids was also found. A large number of the volatiles in A. tequilana Weber var. azul were also detected in tequila extracts, and most of these have been reported as a powerful odorants, responsible for the unique tequila flavor.

    Ube3A (also referred to as E6AP for E6 Associated Protein) is a E3 ubiquitin-protein ligase implicated in the development of Angelman syndrome by controlling degradation of synaptic protein Arc and oncogenic papilloma virus infection by controlling degradation of p53. This article describe the solution NMR structure of the conserved N-terminal domain of human Ube3A (residues 24-87) that contains two residues (Cys44 and Arg62) found to be mutated in patients with Angelman syndrome. The structure of this domain adopts a novel Zn-binding fold we called AZUL (Amino-terminal Zn-finger of Ube3a Ligase). The AZUL domain has a helix-loop-helix architecture with a Zn ion coordinated by four Cys residues arranged in Cys-X{sub 4}-Cys-X{sub 4}-Cys-X{sub 28}-Cys motif. Three of the Zn-bound residues are located in a 23-residue long and well structured loop that connects two {alpha}-helicies.

    Patent races are models of strategic interactions between firms competing to develop an invention. The winning firm secures a patent, protecting the invention from imitation. This paper tests the assumption made about the reward structure in patent races, both in discrete and complex industries. We...... identify patent race winners using detailed information from the patent examination reports at the European Patent Office (EPO). Estimates of a market value equation featuring large, R&D-intensive U.S., European and Japanese firms, show that if firms win patent races, their market value increases...... significantly. We further show that the gain in market value is significantly larger for patent race winners in discrete industries than for firms in complex industries....

From the reading and analysis of the 2013 area documents of all the 48 areas of Capes, a proposal for metrics for patents was developed to be applied in Medicine III programs. Except for the areas Biotechnology, Food Science, Biological Sciences III, Physical Education, Engineering I, III and IV and Interdisciplinary, most areas do not adopt a scoring system for patents. The proposal developed was based on the criteria of Biotechnology, with adaptations. In general, it will be valued, in ascending order, the deposit, the granting and licensing/production. It will also be assigned higher scores to patents registered abroad and whenever there is a participation of students. This proposal can be applied to the item Intellectual Production of the evaluation form, in subsection Technical Production/Patents. The percentage of 10% for academic programs and 40% for Masters Professionals should be maintained. The program will be scored as Very Good when it reaches 400 points or over; Good, between 200 and 399 points; Regular, between 71 and 199 points; Weak up to 70 points; Insufficient, no punctuation.

    This paper surveys some of the patent literature, in particular, it focuses on optimal patent policies. We compare two situations. The first where the government only has a single policy tool to design the optimal patent policy, namely the optimal patent length. In the second situation......, the government uses two policy tools, the optimal breadth and length. We show that theoretical models give very different answers to what is the optimal patent policy. In particular, we show that the optimal patent policy depends among othet things on the price elasticity of demand, the intersectoral elasticity...... of research outputs as well as the degree of compettition in the R&D sector. The actual law on intellectual property, which advocates a unique patent length of 20 years is in general not supported by theoretical models....

    We measure the quantitative importance of labor mobility as a vehicle for the transmission of knowledge and skills across firms. For this purpose we create a unique data set that matches all applications of Danish firms at the European Patent Office to linked employer-employee register data...... for the years 1999-2002. The Danish workforce is split into "R&D workers", who hold a bachelor's or a master's degree in a technical field, and "non{R&D workers". We find that mobile R&D workers ("R&D joiners"') contribute more to patenting activity than immobile R&D workers. Furthermore, R&D workers who have...... previously been employed by a patenting firm ("patent exposed workers") have a larger effect on patenting activity than R&D workers without this experience. Patent exposed R&D joiners constitute the most productive group of workers: for firms that patented prior to 1999, one additional worker of this type...

    - What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discri...

    Patent strategies are endogenous to firm appropriability. However, to what extent does firm’s R&D teams’ engagement with patent experts influence the value of patents? We estimate the relationship between firm’s R&D use of patent functions on patent value in Biotech firms. Controlling...... for characteristics of scientific team, firm effects, and other patent value indicators, we find that having a firm specific (in-house) internal patent function is a driver of patent value. In addition, we find that the way in which patent functions create patent value differs dependent on whether the firm has...... internal patent function or not. In-house patent functions create value through narrow patents, whereas, firms with no in-house patent function create valuable patents by the use of broader scoped patents. Our results point to a strong effect of firm specific patent functions, but also explain how firms...

Foi feita aplicação de questionário de freqüência quantitativa e qualitativa com população infantil atendida no ambulatório de pediatria do Hospital Universitário Gafrée Guinle, Rio de Janeiro. Os dados foram tratados estatisticamente pelo programa SPSS 8.0. Verificou-se que os alimentos pesquisados são ampla e freqüentemente consumidos, sendo introduzidos na dieta, em muitos dos casos, antes da criança completar 1 ano de idade. Sabe-se que os produtos estudados não são adequados nutricionalmente, pois apresentam, além dos corantes, outros aditivos alimentares e não contêm nenhum nutriente importante para o funcionamento do organismo. Em relação aos corantes presentes nos produtos mencionados pela população estudada, constatou-se que os mais informados na rotulagem destes produtos, no item ingredientes, são amarelo crepúsculo, tartrazina e amaranto. Estimando que o teor dos corantes nos alimentos analisados esteja no limite máximo permitido pela legislação, observou-se que a grande maioria das crianças avaliadas pode estar excedendo a ingestão diária aceitável para o corante amaranto e que cerca de 20% da população pode estar excedendo o consumo recomendado para o amarelo crepúsculo. É importante que os valores máximos permitidos de corantes em alimentos, no Brasil, sejam adequados às recomendações realizadas pelo órgão internacional que avalia a segurança dos aditivos, e que ações educativas sejam realizadas.This study aimed at evaluating the intake of solid jelly powder, solid juice powder and soft drinks by children.

    A three-dimensional modular model (MODFLOW) was used to simulate groundwater flow in the Azul River basin, Buenos Aires Province, Argentina, in order to assess the correctness of the conceptual model of the hydrogeological system. Simulated heads satisfactorily match observed heads in the regional water-table aquifer. Model results indicate that: (1) groundwater recharge is not uniform throughout the region but is best represented by three recharge rates, decreasing downgradient, similar to the distribution of soils and geomorphological characteristics; and (2) evapotranspiration rates are larger than previous estimates, which were made by using the Thornthwaite-Mather method. Evapotranspiration rates estimated by MODFLOW agree with results of independent studies of the region. Model results closely match historical surface-flow records, thereby suggesting that the model description of the aquifer-river relationship is correct. Résumé Un modèle modulaire tridimensionnel (MODFLOW) a été utilisé pour simuler les écoulements souterrains dans le bassin de la rivière Azul (Province de Buenos Aires, Argentine), dans le but d'évaluer la justesse du modèle conceptuel du système hydrogéologique. La piézométrie simulée s'ajuste de façon satisfaisante à celle observée pour l'ensemble de la nappe. Les résultats du modèle indiquent que: (1) la recharge de la nappe n'est pas uniforme sur toute la région, mais qu'elle est mieux approchée par trois valeurs différentes, décroissant vers l'aval-gradient, en suivant la même distribution que les sols et les caractéristiques géomorphologiques et (2) l'évapotranspiration est nettement plus importante que prévu initialement à partir de la méthode de Thornthwaite-Mather. Les valeurs d'évapotranspiration fournies par MODFLOW concordent bien avec les résultats d'autres études portant sur la région.

    2009-07-01

    Full Text Available Abstract Patent arterial duct (PAD is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes. Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of

    In this study, cellulose of bagasse from Agave tequilana Weber var. azul was extracted to elaborate nanofibers by the electrospinning technique. Fiber characterization was performed using Transmission Electron Microscopy (TEM), x-ray, Fournier Transform-InfraRed (FT-IR) spectroscopy, and thermal analysis by Differential Scanning Calorimetry-Thermogravimetric Analysis (DSC-TGA). Different diameters (ranging from 54.57 ± 0.02 to 171 ± 0.01 nm) of nanofibers were obtained. Cellulose nanofibers were analyzed by means of x-ray diffraction, where we observed a total loss of crystallinity in comparison with the cellulose, while FT-IR spectroscopy revealed that the hemicellulose and lignin present in the agave bagasse were removed. Thermal analysis showed that nanofibers exhibit enhanced thermal properties, and the zeta potential value (-32.5 mV) demonstrated moderate stability in the sample. In conclusion, the nanofibers obtained provide other alternatives-of-use for this agro-industrial residue and could have potential in various industrial applications, among these encapsulation of bioactive compounds and reinforcing material, to mention a few.

    Full Text Available On July 2002, a study of some physicochemical parameters and their relationship with the benthonic macroinvertebrates community structure on four coriotypes: stone, trash, silt and macrophytes, was carried out in Pozo Azul (Gaira River basin, Magdalena, Colombia. The physicochemical parameters were determined, to a considerable extent, by the geographic characteristics of the system. The water was found to be oxygen saturated, and intermediate compounds of the organic matter stabilization, such as nitrites and ammonium, there were found 588 individuals distributed in 11 orders and 38 families. The most representative orders were Trichoptera, Coleoptera, Diptera and Ephemeroptera. The most representative families were Baetidae, Simullidae, Perlidae, Chironomidae, and Hydropsychidae, in this rank of abundance. The BMWP index for the relationship between the community structure and the water quality (adapted by Universidad del Valle, Cali, Colombia was calculated. According to this index the water quality was optimum. Also, given the general characteristics of the site studied, the water mass quality was classified as good and oligosaprobit, based on the saprobit ecology. It is possible that this state was reached due to stabilization after a small perturbation induced by coffee cultivation in the zone.

    Full Text Available This study explores technology clusters through patent analysis. The aim of exploring technology clusters is to grasp competitors’ levels of sustainable research and development (R&D and establish a sustainable strategy for entering an industry. To achieve this, we first grouped the patent documents with similar technologies by applying affinity propagation (AP clustering, which is effective while grouping large amounts of data. Next, in order to define the technology clusters, we adopted the term frequency-inverse document frequency (TF-IDF weight, which lists the terms in order of importance. We collected the patent data of Korean electric car companies from the United States Patent and Trademark Office (USPTO to verify our proposed methodology. As a result, our proposed methodology presents more detailed information on the Korean electric car industry than previous studies.

    2017-11-01

    Microbial technologies often serve as the basis of fundamental research tools in molecular biology. These present a variety of ethical, legal and social issues concerning their patenting. This commentary presents several case studies of these issues across three major microbiological tools: CRISPR, viral vectors and antimicrobial resistance drugs. It concludes that the development of these technologies-both scientifically and commercially-depend, in part, on the patent regime available for each, and researchers' willingness to enforce those patents against others. © FEMS 2017.

    Full Text Available The patent system has been able to provide the protection for the achievements of different technologies and in that way it has supported further development and growth of the industry where those achievements were implemented. Modern technologies like information technology and biotechnology with genetic engineering that appeared in the 70s have overgrown the frames of the existing patent system because of their exponential development during the last thirty years. Industry that invests a huge amount of money in these technologies, especially in the field of biotechnology, where the results are very uncertain, has started to claim changes in the patent system.

  8. The academic advantage: gender disparities in patenting.

    Science.gov (United States)

    Sugimoto, Cassidy R; Ni, Chaoqun; West, Jevin D; Larivière, Vincent

    2015-01-01

    We analyzed gender disparities in patenting by country, technological area, and type of assignee using the 4.6 million utility patents issued between 1976 and 2013 by the United States Patent and Trade Office (USPTO). Our analyses of fractionalized inventorships demonstrate that women's rate of patenting has increased from 2.7% of total patenting activity to 10.8% over the nearly 40-year period. Our results show that, in every technological area, female patenting is proportionally more likely to occur in academic institutions than in corporate or government environments. However, women's patents have a lower technological impact than that of men, and that gap is wider in the case of academic patents. We also provide evidence that patents to which women--and in particular academic women--contributed are associated with a higher number of International Patent Classification (IPC) codes and co-inventors than men. The policy implications of these disparities and academic setting advantages are discussed.

  9. Religious coalition opposes gene patents.

    Science.gov (United States)

    James, J S

    1995-05-19

    The biotechnology industry is concerned about a coalition of mainstream religious leaders, working with Jeremy Rifkin of the Foundation of Economic Trends, who oppose the patenting of human and animal life forms, body parts, and genes. The coalition called a press conference on May 18 to ask the government to prohibit the current patenting practices for genetic engineering. The biotechnology industry argues that patents indicate that a company's research tool has significant value, and encourages capitalists to invest their dollars in the development of new treatments for diseases. They also argue that the 29 biotech drugs that are on the market have been developed as a result of patents on genes. Although most business leaders are united in opposing restrictions, many scientists are divided, citing both religious and scientific reasons.

    Zabala, M E; Manzano, M; Vives, L

    2015-06-15

    The Pampean plain is the most productive region in Argentina. The Pampeano Aquifer beneath the Pampean plain is used mostly for drinking water. The study area is the sector of the Pampeano Aquifer underlying the Del Azul Creek basin, in Buenos Aires province. The main objective is to characterize the chemical and isotopic compositions of groundwater and their origin on a regional scale. The methodology used involved the identification and characterization of potential sources of solutes, the study of rain water and groundwater chemical and isotopic characteristics to deduce processes, the development of a hydrogeochemical conceptual model, and its validation by hydrogeochemical modelling with PHREEQC. Groundwater samples come mostly from a two-depth monitoring network of the "Dr. Eduardo J. Usunoff" Large Plains Hydrology Institute (IHLLA). Groundwater salinity increases from SW to NE, where groundwater is saline. In the upper basin groundwater is of the HCO3-Ca type, in the middle basin it is HCO3-Na, and in the lower basin it is ClSO4-NaCa and Cl-Na. The main processes incorporating solutes to groundwater during recharge in the upper basin are rain water evaporation, dissolution of CO2, calcite, dolomite, silica, and anorthite; cationic exchange with Na release and Ca and Mg uptake, and clay precipitation. The main processes modifying groundwater chemistry along horizontal flow at 30 m depth from the upper to the lower basin are cationic exchange, dissolution of silica and anorthite, and clay precipitation. The origin of salinity in the middle and lower basin is secular evaporation in a naturally endorheic area. In the upper and middle basins there is agricultural pollution. In the lower basin the main pollution source is human liquid and solid wastes. Vertical infiltration through the boreholes annular space during the yearly flooding stages is probably the pollution mechanism of the samples at 30 m depth. Copyright © 2015 Elsevier B.V.

    2002-08-01

    In 1999, the Instituto Superior de Ciências Aplicadas (ISCA Faculdades de Limeira) started a project to build an observatory and initiate several astronomy related activities in the city of Limeira and region (São Paulo state) with the aim of teaching and popularizing astronomy. After contracting teachers, a technician and an intern, the Morro Azul Observatory was inaugurated in March 2000 as a part of the geosciences department of ISCA Faculdades. This poster describes the development phases of the Observatory, the activities initiated by the Observatory, and assesses the impact of the project. Several issues will be discussed such as the criteria for choosing the site, buildings, instruments, group visits, and particularly the goals that were reached. The Observatory, as described here, serves as a model for other centers with the same purpose in the country. The achievements of this project include the creation of two astronomical disciplines for the geography course and liaisons with other courses such as tourism, pedagogy, social communication and engineering. New activities were initiated, educational materials created, and the Observatory is now part of the regions teaching network and is in contact with other Brazilian and foreign centers. This poster presents the results from report analyses, visitor records, the local media, goal strategy assessment, and the current state of the project. It concludes with an evaluation of the social commitment of the Observatory, its initiatives for the constant renewal and growth of the project, its policy of maintaining the activities and interchange with other national and international astronomy centers, and the future perspectives in terms of its contribution for the research in science education.

  13. Patent Law for Computer Scientists

    Science.gov (United States)

    Closa, Daniel; Gardiner, Alex; Giemsa, Falk; Machek, Jörg

    More than five centuries ago the first patent statute was passed by the Venetian senate. It already had most of the features of modern patent law, recognizing the public interest in innovation and granting exclusive right in exchange for a full disclosure. Some 350 years later the industrial revolution led to globalisation. The wish to protect intellectual property on a more international level evolved and supranational treaties were negotiated. Patent laws are still different in many countries, however, and inventors are sometimes at a loss to understand which basic requirements should be satisfied if an invention is to be granted a patent. This is particularly true for inventions implemented on a computer. While roughly a third of all applications (and granted patents) relate, in one way or another, to a computer, applications where the innovation mainly resides in software or in a business method are treated differently by the major patent offices. The procedures at the USPTO, JPO and EPO and, in particular, the differences in the treatment of applications centring on software are briefly explained. In later sections of this book, a wealth of examples will be presented. The methodology behind the treatment of these examples is explained.

    Full Text Available A adsorção é uma das técnicas empregadas com sucesso para remoção efetiva da cor presente em efluentes têxteis. Com o objetivo de avaliar os diferentes parâmetros adsortivos, bem como determinar a eficiência de um adsorvente alternativo desenvolvido a partir de lodo residual têxtil na remoção de corantes, foram determinadas curvas de cinética de adsorção e isotermas. Por meio dos dados cinéticos e de equilíbrio obtidos, verificou-se que a 25ºC a adsorção foi favorável para todos os corantes, sendo esta a melhor condição para os corantes RO16 e RR2 na ausência de sais. Para o corante RR141, a adição de NaCl aumentou a capacidade de adsorção do adsorvente no equilíbrio e a adição de Na2SO4 favoreceu a adsorção para o corante RO16, ao contrário do que se observou para os outros dois corantes. A quantidade máxima de corante adsorvida por unidade de massa de adsorvente (q max nas melhores condições adsortivas para os corantes RO16, RR2 e RR141 foi de 81,30, 53,48 e 78,74 mg.g-1, respectivamente.The adsorption is one of the techniques that have been successfully used for effective removal of the dyes present in textile effluents. With the objective to evaluate the different adsorptive parameters, as well as determining the efficiency of one alternative adsorbent in the removal of dyes, kinetics and equilibrium data of adsorption were determined. By the kinetic data and of equilibrium, it was verified that the adsorption was favorable for all the dyes in 25ºC, being the best condition for the dye RO16 and RR2 in the total absence of salt. For the dye RR141, the addition of NaCl increased the adsorption capacity of adsorbent in the equilibrium and the addition of Na2SO4 favored the adsorption for the dye RO16, in contrast to what was observed for the two other dyes. The maximum quantity of dye adsorbed per unit mass of adsorbent (q max in the best adsorptive conditions for the dyes RO16, RR2 and RR141 was of 81

    2012-11-01

    Full Text Available Patent network analysis, an advanced method of patent analysis, is a useful tool for technology management. This method visually displays all the relationships among the patents and enables the analysts to intuitively comprehend the overview of a set of patents in the field of the technology being studied. Although patent network analysis possesses relative advantages different from traditional methods of patent analysis, it is subject to several crucial limitations. To overcome the drawbacks of the current method, this study proposes a novel patent analysis method, called the intelligent patent network analysis method, to make a visual network with great precision. Based on artificial intelligence techniques, the proposed method provides an automated procedure for searching patent documents, extracting patent keywords, and determining the weight of each patent keyword in order to generate a sophisticated visualization of the patent network. This study proposes a detailed procedure for generating an intelligent patent network that is helpful for improving the efficiency and quality of patent analysis. Furthermore, patents in the field of Carbon Nanotube Backlight Unit (CNT-BLU were analyzed to verify the utility of the proposed method.

  2. Patents, Inducement Prizes, and Contestant Strategy

    DEFF Research Database (Denmark)

    Davis, Jerome; Davis, Lee N.

    2006-01-01

    Debate over the merits of patents versus inducement prizes has tended to ignore the signaling roles of patents, and totally ignores the impact of patent signaling on prize contests. This paper asks: How does patent signaling affect the strategic choices of firms considering entering prize contests......? First, we consider contests that do not allow patenting, then contests that do. If patenting is not allowed, we argue, patent-holders, both internal and external to the contest, can adversely impact prize contests by claiming prize winner violation of their patents, and suing for damages. The likelihood...... of such challenges being made can deter entry, particularly in contests requiring large sunk costs. Furthermore, the firm's decisionmaking process will discriminate against entering prize contests and favor R&D projects with patentable outcomes. Together, these problems may circumscribe any future wider role...

  5. Chemical-mineralogical characterization and Moessbauer spectroscopy of aquamarine from Pedra Azul, Northeast of Minas Gerais

    International Nuclear Information System (INIS)

    Viana, Rubia Ribeiro; Jordt-Evangelista, Hanna; Costa, Geraldo Magela da

    2001-01-01

    Aquamarines from three pegmatites located the vicinities of the Pedra Azul city, Minas Gerais state, were investigated in terms of chemical composition, physical properties and Moessbauer spectroscopy. The small lenticular pegmatite bodies are usually less than 5 m wide and exhibit a conspicuous mineralogical and textural zoning. The last thermal event in these pegmatites, determined by K-Ar method in muscovite, is of Neo proterozoic age, coincident with the late stages of the Brasiliano tectono- metamorphic cycle. Chemical analyses showed that sodium is the alkali with higher contents in the aquamarines, thus enabling their classification as sodic beryls. In zoned samples there is an increase of Fe as well as Mn from center to border, while no systematic variation could be detected for other elements. The specific gravity of 2.72 to 2.80 g/cm 3 is higher than the values determined for samples from other pegmatites of Minas Gerais. The refraction indices are ne=1.569 - 1.579 and NW= 1.573 - 1.581 and the birefringence varies from 0.002 to 0.008. The refraction indices increase with the Be O content. The color of aquamarines varies from medium to light blue, sometimes greenish blue. Moessbauer spectra obtained at room temperature and at 80 K show that Fe 2+ is the main chromophore-ion and suggest that the iron is present in octahedral sites as well as in the structural channels. Moessbauer spectra also indicate that the incorporation of Fe 3+ may cause a shift from deep blue to light blue colors. Based on their aquamarine composition the pegmatites were classified as barren, poor in rare alkalis (Li, Rb, Cs) and therefore little differentiated. The relatively simple mineralogy and the lack of lithium minerals such as lepidolite and spodumene confirm this classification. Thus, the composition of beryl can be used as a tracer for the prospection of pegmatites with different degrees of differentiation and consequently with different types of mineralization. (author)

    Patent documentations are important scientific and technical documentations, which gather legal information, technical information and economic information together. According to WIPO forecasts, making full use of patent documentation can save 40% of research funding and 60% of the study period. Foreign patent documentations are the world's most valuable patent documentations, and many original technologies that have significant influence are first disclosed in foreign patent documentation. Studying and making use of foreign patent documentations can improve our starting point of scientific and technological innovation, and reduce the research investment. This paper analyzes foreign patent documentation and, combining with the actual development of nuclear technology in our country, makes specific recommendations for patent documentation research.

  13. Effect of firm variables on patent price

    Directory of Open Access Journals (Sweden)

    Shyam Sreekumaran Nair

    2012-03-01

    Full Text Available In this study, using singleton patent auction price data from Ocean Tomo, LLC, we analyse the effect of firm variables on patent price. Patents owned by small firms attract higher price than patents owned by large firms, if they engage in multi-country filings. The patents owned by small firms get cited more than the patents owned by large firms. The patents owned by individual inventors attract a higher price than the patents owned by organisations when multi-country filings are not included. We believe that the lack of resources is preventing individual inventors from engaging in multi-country filings and maximising the revenue from their invention. A larger representative data should be used to replicate the results before generalising it.

  10. Entrepreneurial patent management in pharmaceutical startups.

    Science.gov (United States)

    Holgersson, Marcus; Phan, Tai; Hedner, Thomas

    2016-07-01

    Startups fill an increasingly important role as innovators in the pharmaceutical industry, and patenting is typically central to their success. This article aims to explore patent management in pharmaceutical startups. The results show that startups need to deal with several challenges related to patenting and an 'entrepreneurial' approach to patent management is called for. Resource constraints, venture capital provision, exits and other conditions and events must be readily considered in the patent management process to build a successful pharmaceutical venture, something that could benefit the pharmaceutical industry as a whole.

    2002-01-01

    A method of data mining represents related patents in a multidimensional space. Distance between patents in the multidimensional space corresponds to the extent of relationship between the patents. The relationship between pairings of patents can be expressed based on weighted combinations of several predicates. The user can select portions of the space to perceive. The user also can interact with and control the communication of the space, focusing attention on aspects of the space of most interest. The multidimensional spatial representation allows more ready comprehension of the structure of the relationships among the patents.

  12. The Patentability of Stem Cells in Australia.

    Science.gov (United States)

    Petering, Jenny; Cowin, Prue

    2015-07-01

    The potential therapeutic applications of stem cells are unlimited. However, the ongoing political and social debate surrounding the intellectual property and patenting considerations of stem cell research has led to the implementation of strict legislative regulations. In Australia the patent landscape surrounding stem cells has evolved considerably over the past 20 years. The Australian Patents Act 1990 includes a specific exclusion to the patentability of human beings and of biological processes for their generation. However, this exclusion has received no judicial consideration to date, and so its scope and potential impact on stem cell patents is unclear.

    The total of 137 US patents on spacer grids patented from 1968 through 1993 are analyzed and summarized. Database is constituted with designing the appropriate fields by which each patent can be identified. The fields consist of patent number, inventor, assignee, date of patent, title and major foci of the patent. The major foci are again classified by detailed subjects such as the fretting failure and fuel rod support-related, the strength-related, the fabrication-related as for mechanical subjects, while the cooling performance-related and the pressure drop-related as for thermal-hydraulic one. The 92% of the patents analyzed were issued form nuclear companies of USA, France and Germany. Among the patents dealing with mechanical subjects, the fretting failure and fuel rod support-related is more than the pressure drop-related among the patents of thermal-hydraulic subjects. The number of patents issued from Japan ranks just after Germany i.e., the 4th country.

    1995-03-01

    This document contains US patents on terrestrial photovoltaic (PV) power applications, including systems, components, and materials as well as manufacturing and support functions. The patent entries in this document were issued from 1991 to 1993. The entries were located by searching USPA, the database of the US Patent Office. The final search retrieved all patents under the class ``Batteries, Thermoelectric and Photoelectric`` and the subclasses ``Photoelectric,`` ``Testing,`` and ``Applications.`` The search also located patents that contained the words ``photovoltaic(s)`` or ``solar cell(s)`` and their derivatives. After the initial list was compiled, most of the patents on the following subjects were excluded: space photovoltaic technology, use of the photovoltaic effect for detectors, and subjects only peripherally concerned with photovoltaic. Some patents on these three subjects were included when ft appeared that those inventions might be of use in terrestrial PV power technologies.

  20. Patent first, ask questions later: morality and biotechnology in patent law.

    Science.gov (United States)

    Bagley, Margo A

    2003-12-01

    This Article explores the U.S. "patent first, ask questions later" approach to determining what subject matter should receive patent protection. Under this approach, the U.S. Patent and Trademark Office (USPTO or the Agency) issues patents on "anything under the sun made by man," and to the extent a patent's subject matter is sufficiently controversial, Congress acts retrospectively in assessing whether patents should issue on such interventions. This practice has important ramifications for morally controversial biotechnology patents specifically, and for American society generally. For many years a judicially created "moral utility" doctrine served as a type of gatekeeper of patent subject matter eligibility. The doctrine allowed both the USTPO and courts to deny patents on morally controversial subject matter under the fiction that such inventions were not "useful." The gate, however, is currently untended. A combination of the demise of the moral utility doctrine, along with expansive judicial interpretations of the scope of patent-eligible subject matter, has resulted in virtually no basis on which the USTPO or courts can deny patent protection to morally controversial, but otherwise patentable, subject matter. This is so despite position statements by the Agency to the contrary. Biotechnology is an area in which many morally controversial inventions are generated. Congress has been in react-mode following the issuance of a stream of morally controversial biotech patents, including patents on transgenic animals, surgical methods, and methods of cloning humans. With no statutory limits on patent eligibility, and with myriad concerns complicating congressional action following a patent's issuance, it is not Congress, the representative of the people, determining patent eligibility. Instead, it is patent applicants, scientific inventors, who are deciding matters of high public policy through the contents of the applications they file with the USTPO. This Article

    2015-01-01

    We analyzed gender disparities in patenting by country, technological area, and type of assignee using the 4.6 million utility patents issued between 1976 and 2013 by the United States Patent and Trade Office (USPTO). Our analyses of fractionalized inventorships demonstrate that women’s rate of patenting has increased from 2.7% of total patenting activity to 10.8% over the nearly 40-year period. Our results show that, in every technological area, female patenting is proportionally more likely to occur in academic institutions than in corporate or government environments. However, women’s patents have a lower technological impact than that of men, and that gap is wider in the case of academic patents. We also provide evidence that patents to which women—and in particular academic women—contributed are associated with a higher number of International Patent Classification (IPC) codes and co-inventors than men. The policy implications of these disparities and academic setting advantages are discussed. PMID:26017626

Uno de ellos está sometido a agricultura permanente y el otro conserva un pastizal natural bajo pastoreo y quemas no programados. Este último sector presentó en promedio una densidad de 70.000 sem m-2 contra 36.720 sem m-2 en el primero. La representación de semillas de especies nativas se redujo notablemente en el ambiente agrícola. Stipa caudata con 31360 sem m-2 resultó la especie más abundante en el pastizal. En el ambiente de cultivo, su densidad se redujo a 9940 sem m-2 y fue superada por Chenopodium album con 10560 sem m-2. La similitud en la composición del banco fue de 55% en términos cualitativos y 27% en términos cuantitativos. Estos resultados evidencian que, en el área de estudio, el reemplazo del pastizal natural por agricultura reduce notoriamente las reservas de semillas y modifica la composición cualitativa y cuantitativa del banco con una elevada pérdida en la proporción de especies nativas.In order to evaluate the impact of agriculture on the potential flora of grasslands of the sierras of Azul (Buenos Aires Province, Argentina, the soil seed bank in the top 20 cm from two adjacent areas on the first foothill spurs were compared.

    Parkhurst, R.W.; Serbinowski, P.A.

    1991-01-01

    Simultaneous superconductivity research activities by different entities have resulted in numerous US patent applications, some of which may claim identical inventions and thus likely will be involved in interference proceedings in the US Patent and Trademark Office to determine which inventors are entitled to priority of invention and the resulting US patent. The determination in an interference proceeding of what inventors were the first-to-invent a patentable invention is contrasted with the patent systems in the rest of the world where the first inventor to file his patent application automatically gains priority. This issue and other aspects of US patent law are the subjects of criticism of US patent law and practice in the current Uruguay round of talks on the General Agreement on Trade and Tariffs (GATT). Interesting aspects of each of these subjects will be discussed

    Some fundamental biotechnologies hold unprecedented potential to eradicate many incurable diseases. However, in absence of regulations, the power of patent makes the future use of some important biotechnology in few institution's hands. The excessive patents restrict researcher access to the fundamental technologies. It generates concerns and complaints of deteriorating the public health and social welfare. Furthermore, intellectual curiosities, funding, respect among colleagues etc., rather than patents, are the real motivations driving a major ground-breaking discoveries in biotechnology. These phenomena reveal that some biotechnology patents are alienated from the purpose of patent system. Therefore, it is necessary to take some approaches to stop over-patenting these fundamental biotechnology inventions. This article proposes a model regulatory framework for controlling biotechnology patent alienating from the purpose of patent system.

    Full Text Available Resumo: Nos últimos anos, os pigmentos naturais de urucum têm sido substancialmente utilizados pelas indústrias de alimentos para dar cor a produtos tais como: massas alimentícias, cereais, produtos de panificação, gelados comestíveis, sobremesas, condimentos, etc. Dentre esses pigmentos destaca-se a bixina, um éster monometílico do ácido dicarbixílico alfa-norbixina pouco solúvel em óleo e anorbixina um caratenóide diácido carboxilico. Em virtude da crescente aplicação industrial  dos corantes naturais, este trabalho teve como objetivo determinar a solubilidade desses pigmentos em diferentes solventes, por meio de espectrofotometria UV-vis. Foram preparadas soluções sob as mesmas condições, utilizando-se os solventes: acetona, álcool etílico, álcool isopropílico, dimetilsulfóxido e clorofómio. A absorbância foi medida em função do comprimento de onda de cada solução por meio da análise dos espectros de UV-Vis, na região de 800 a 200 nm. Os dados obtidos referentes às análises no UV-Vis confirmaram a maior eficácia do Dimetilsulfóxido (DMSO na dissolução da bixinae  e da acetona para o norbixina  em relação aos outros solventes.

  16. Patents - Superconductor materials, processes and devices

    International Nuclear Information System (INIS)

    Test, A.

    1987-01-01

    A patent is a grant by a country to an inventor or his assignee of the right to exclude others for a limited period of time from making, using or selling the patented invention within its territory. It is reported that basic patents have been filed by IBM and the University of Houston to protect a broad range of warm superconducting materials or compounds. It is believed that other researchers are seeking patents to protect related or improved materials, processes and apparatus. Because of the importance of this field and to speed up the patent process, the United States Patent Office is giving, upon request, special expedited status to these patent applications. A survey of Japanese companies shows that more than 1500 patents have been applied for in Japan relating to superconducting materials, compositions, apparatus using superconductors and improvements. It appears that the goal of the Japanese companies is to obtain a patent position in Japan so that they can trade with companies wishing to do business in Japan for rights in other parts of the world

    Most countries focus on industries with high technology and the governments grant subsidies to innovating firms. However, there has been remarkable few studies of the performance of innovative firms or industries. This study examines the performance of patent active firms compared to the non-patenting...... firms within the manufacturing sector in Denmark. Performance is measured both by growth in employment as well as in the return on equity and profit share in turnover. The results suggest that differences in performance of patenting and non-patenting firms are very small, which questions the political...

  18. The History of Patenting Genetic Material.

    Science.gov (United States)

    Sherkow, Jacob S; Greely, Henry T

    2015-01-01

    The US Supreme Court's recent decision in Association for Molecular Pathology v. Myriad Genetics, Inc. declared, for the first time, that isolated human genes cannot be patented. Many have wondered how genes were ever the subjects of patents. The answer lies in a nuanced understanding of both legal and scientific history. Since the early twentieth century, "products of nature" were not eligible to be patented unless they were "isolated and purified" from their surrounding environment. As molecular biology advanced, and the capability to isolate genes both physically and by sequence came to fruition, researchers (and patent offices) began to apply patent-law logic to genes themselves. These patents, along with other biological patents, generated substantial social and political criticism. Myriad Genetics, a company with patents on BRCA1 and BRCA2, two genes critical to assessing early-onset breast and ovarian cancer risk, and with a particularly controversial business approach, became the antagonist in an ultimately successful campaign to overturn gene patents in court. Despite Myriad's defeat, some questions concerning the rights to monopolize genetic information remain. The history leading to that defeat may be relevant to these future issues.

    This document contains US patents on terrestrial photovoltaic (PV) power applications, including systems, components, and materials, as well as manufacturing and support functions. The patent entries in this document were issued from 1988 through 1990. The entries were located by searching USPA, the data base of the US Patent Office. The final search retrieved all patents under the class ``Batteries, Thermoelectric and Photoelectric`` and the subclasses ``Photoelectric,`` ``Testing,`` and ``Applications.`` The search also located patents that contained the words ``photovoltaic(s)`` or ``solar cell(s)`` and their derivatives. A manual search of the patents in the Solar Energy Research Institute (SERI) patent file augmented the data base search. After the initial list was compiled, most of the patents on the following subjects were excluded: space photovoltaic technology, use of the photovoltaic effect for detectors and subjects only peripherally concerned with photovoltaics. Some patents on these three subjects were included when it appeared that those inventions might be of use in terrestrial PV power technologies.

    2016-07-01

    This study has as its goal the synthesis of a mixed oxide system type CeO{sub 2} - TiO{sub 2}, through the polymeric precursor method, to be used in heterogeneous photocatalysis. The synthesized materials were characterized by Thermogravimetry (TG), Derivative Thermogravimetry (DTG), Differential Thermal Analysis (DTA) and X-Ray Diffraction (XRD). The results of the thermal analysis showed in what temperature ranges certain events occur such as the formation of cerium oxide between 600 and 800 ° C, which refers to the crystallization of the material. Regarding the formation of titanium oxide, events between 600 and 800 ° C are perceived, which suggests the transformation of anatase to rutile phase. The XRD analysis showed no occurrence of the same phase for all materials, meaning that there is a variation in the formation of phases according to concentration of precursor for each sample. Noteworthy are the formation of CeO{sub 2} for Ce75-Ti25 and Ce50-Ti50 concentrations, with cubic crystal structure of the fluorite type. In Ce75-Ti25 and Ce25-Ti75 it is present the TiO{sub 2} in the anatase and rutile phase, with crystal structure of the tetragonal and tetrahedron type, respectively, as well as the formation of CeTi{sub 2}O{sub 6} in Ce50-Ti50 and Ce25-Ti75, with structure monoclinic. From these analyses, it is possible to see which samples, and in which temperatures of calcination the material has increased crystallinity, making the choice for their application in heterogeneous photocatalysis, aiming the degradation of methylene blue dye. Among the tested materials for methylene blue, the sample that stood out was the Ce50-Ti50, with calcination temperature of 800 °C, with values close to 50% degradation, because it was the sample that showed higher dye adsorption capacity, which is the step that precedes photodegradation.

    The contamination of water resources is one of the greatest environmental problems today. Among the polluting sources are the textile industries due to the production of large volumes of effluent, often treated inefficiently. The main reason for the environmental impact of the rejected materials is the presence of dyes such as azo reactive compounds that can generate by-products with carcinogenic and mutagenic effects. They may also include anthraquinone type compounds, which are highly resistant to degradation and persist in the effluent for a long time. The purpose of this study is the use of photo-Fenton processes assisted by artificial or solar light, using immobilized iron on chitosan beads, crosslinked with glutaraldehyde, for the anthraquinone type compound Blue QR-19 standard dye degradation in aqueous solutions. The obtained spheres showed a regular size and 4.0 mm diameter. The results showed 90% discoloration of the system within 180 minutes and a 60% total organic carbon (TOC)reduction for the photo-Fenton system using artificial light. For the system using sunlight, the total discoloration was achieved in 120 minutes and the TOC value decreased 70%. Also observed was that iron remained in the polymeric matrix after the treatment, thus allowing reuse. (author)

    2016-08-01

    Agave (Agave tequilana Weber var. Azul) is an industrially important crop in México since it is the only raw material appropriate to produce tequila, an alcoholic beverage. Nowadays, however, these plants have also a nutritional interest as a source of functional food ingredients, owing to the prebiotic potential of agave fructans. In this study, a Box-Behnken design was employed to determine the influence of temperature, liquid:solid ratio and time in a maceration process for agave fructan extraction and optimization. The developed regression model indicates that the selected study variables were statistical determinants for the extraction yield, and the optimal conditions for maximum extraction were a temperature of 60 °C, a liquid:solid ratio of 10:1 (v/w) and a time of 26.7 min, corresponding to a predicted extraction yield of 37.84%. Through selective separation via precipitation with ethanol, fructans with a degree of polymerization of 29.1 were obtained. Box-Behnken designs are useful statistical methods for optimizing the extraction process of agave fructans. A mixture of carbohydrates was obtained from agave powder. This optimized method can be used to obtain fructans for use as prebiotics or as raw material for obtaining functional oligosaccharides. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

    Genetic variation in three forms of asexually propagated Agave tequilana Weber var. 'Azul' plants namely offsets, bulbils and in vitro cultured individuals was studied by AFLP analysis. Low levels of variation were observed between mother plants and offsets and a higher level between mother plant and bulbils. Families obtained from commercial plantations showed lower levels of variation in comparison to families grown as ornamentals. No variation was observed between the original explant and four generations of in vitro cultured plants. Epigenetic variation was also studied by analyzing changes in methylation patterns between mother plants and offspring in each form of asexual reproduction. Offsets and bulbils showed an overall decrease in methylation whereas in vitro cultured plants showed patterns specific to each generation: Generations 1 and 4 showed overall demethylation whereas Generations 2 and 3 showed increased methylation. Analysis of ESTs associated with transposable elements revealed higher proportions of ESTs from Ty1-copia-like, Gypsy and CACTA transposable elements in cDNA libraries obtained from pluripotent tissue suggesting a possible correlation between methylation patterns, expression of transposable element associated genes and somaclonal variation.

    Full Text Available This study presents the effect of water level variation on the assemblages of herbaceous species in Mourão I Reservoir, Lago Azul State Park, Southern Brazil. The structure and distribution of populations was examined in February (dry period and April (rainy period, 2011, in two transects. These transects started at the forest edge towards the center of the lake. The end of the transect coincided with the end of the plants within the lake. On every two meters along of the transects we sampled a wooden square of 0.25 m2 for species biomass analysis.The macrophyte stand was composed entirely of emergent species. Considering the periods, most species were less frequent in the rainy period (April, but Ipomea ramosissima (Poir. Choisy, Commelina nudiflora L., Eleocharis acuntagula (Roxb. Schult. and Verbena litorales (Kunth. had their frequency increased during this period, probably due to their resistance. The influence of flood as measured by the NMDS point out that both before and after the flood, there are plots with distinct compositions and biomass. The water level variation affects the dynamics of plant composition and structure in marginal areas of the Reservoir.

    2003-01-01

    On July 2002, a study of some physicochemical parameters and their relationship with the benthonic macro invertebrates community structure on four coriotypes: stone, trash, silt and macrophytes, was carried out in Pozo Azul (Gaira River Basin, Magdalena, Colombia). The physicochemical parameters were determined, to a considerable extent, by the geographic characteristics of the system. The water was found to be oxygen saturated, and intermediate compounds of the organic matter stabilization, such as nitrites and ammonium, there were found 588 individuals distributed in 11 orders and 38 families. The most representative orders were trichoptera, coleoptera, diptera and ephemeroptera. The most representative families were baetidae, simullidae, perlidae, chironomidae, and hydropsychidae, in this rank of abundance. The BMWP index for the relationship between the community structure and the water quality (adapted by Universidad del Valle, Cali, Colombia) was calculated. According to this index the water quality was optimum. Also, given the general characteristics of the site studied, the water mass quality was classified as good and oligosaprobit, based on the saprobit ecology. It is possible that this state was reached due to stabilization after a small perturbation induced by coffee cultivation in the zone

    Microfluidic devices offer control over low-volume samples in order to achieve high-throughput analysis, and reduce turnaround time and costs. Their efficient commercialisation has implications for biomedical sciences, veterinary medicine, environmental monitoring and industrial applications. In particular, market diffusion of microfluidic laboratory and point-of-care diagnostic devices can contribute to the improvement of global health. In their commercialisation, consultancy and patent protection are essential elements that complement academic publishing. The awareness of knowledge transfer strategies can help academics to create value for their research. The aim of this article is to provide a guidance to (1) overview the terminology in patent law, (2) elucidate the process of filing a patent in the US, EU, Japan and internationally, (3) discuss strategies to licence a patent, and (4) explain tactics to defend a patent in a potential infringement. Awareness of the patent law and rights allows obtaining optimised, valid and valuable patents, while accelerating implementation to market route. Striking a balance between academic publishing, consultancy to industry and patent protection can increase commercial potential, enhance economic growth and create social impact.

    2011-09-01

    Herbal drugs are gaining worldwide prominence due to their distinct advantages. Developing countries have started exploring the ethnopharmacological approach of drug discovery and have begun to file patents on herbal drugs. The expansion of R&D in Indian herbal research organizations and presence of manufacturing units at non-Indian sites is an indication of the capability to develop new products and processes. The present study attempts to identify innovations in the Indian herbal drug sector by analyzing the patenting trends in India, US and EU. Based on key word and IPC based search at the IPO, USPTO, Esp@cenet and WIPO databases, patent applications and grant in herbal drugs by Indian applicants/assignees was collected for the last ten years (from 1st January 2001 to 31st October 2010). From this collection patents related to human therapeutic use only were selected. Analysis was performed to identify filing trends, major applicants/assignees, disease area and major plant species used for various treatments. There is a gradual increase in patent filing through the years. In India, individual inventors have maximum applications and grants. CSIR, among research organizations and Hindustan Unilever, Avesthagen, Piramal Life Science, Sahajanand Biotech and Indus Biotech among the companies have the maximum granted patents in India, US and EU respectively. Diabetes, cancer and inflammatory disorders are the major areas for patenting in India and abroad. Recent patents are on new herbal formulations for treatment of AIDS, hepatitis, skin disorders and gastrointestinal disorders. A majority of the herbal patents applications and grants in India are with individual inventors. Claim analysis indicates that these patents include novel multi-herb compositions with synergistic action. Indian research organizations are more active than companies in filing for patents. CSIR has maximum numbers of applications not only in India but also in the US and EU. Patents by research

    Patent trolls (or sharks) are small patent holding individuals or firms who trap R&D intense manufacturers in patent infringement situations in order to receive damage awards for the illegitimate use of their technology. While of great concern to management, their existence and impact for both...... corporate decision makers and policy makers remains to be fully analyzed from an academic standpoint. In this paper we show why patent sharks can operate profitably, why they are of growing concern, how manufacturers can forearm themselves against them, and which issues policy makers need to address. To do...... so, we map international indemnification rules with strategic rationales of small patent-holding firms within a game-theoretical model. Our central finding is that the courts’ unrealistic consideration of the trade-offs faced by inadvertent infringers is a central condition for sharks to operate...

  14. Patent Keyword Extraction for Sustainable Technology Management

    2018-04-01

    Full Text Available Recently, sustainable growth and development has become an important issue for governments and corporations. However, maintaining sustainable development is very difficult. These difficulties can be attributed to sociocultural and political backgrounds that change over time [1]. Because of these changes, the technologies for sustainability also change, so governments and companies attempt to predict and manage technology using patent analyses, but it is very difficult to predict the rapidly changing technology markets. The best way to achieve insight into technology management in this rapidly changing market is to build a technology management direction and strategy that is flexible and adaptable to the volatile market environment through continuous monitoring and analysis. Quantitative patent analysis using text mining is an effective method for sustainable technology management. There have been many studies that have used text mining and word-based patent analyses to extract keywords and remove noise words. Because the extracted keywords are considered to have a significant effect on the further analysis, researchers need to carefully check out whether they are valid or not. However, most prior studies assume that the extracted keywords are appropriate, without evaluating their validity. Therefore, the criteria used to extract keywords needs to change. Until now, these criteria have focused on how well a patent can be classified according to its technical characteristics in the collected patent data set, typically using term frequency–inverse document frequency weights that are calculated by comparing the words in patents. However, this is not suitable when analyzing a single patent. Therefore, we need keyword selection criteria and an extraction method capable of representing the technical characteristics of a single patent without comparing them with other patents. In this study, we proposed a methodology to extract valid keywords from

Esta última, constituí-se numa área predominantemente agrícola, onde a cultura de trigo, principal atividade agrícola, se alterna com culturas de verão como milho, girassol e soja. Com o objetivo de caracterizar globalmente o banco de sementes da área agrícola, foram analisados o conteúdo de sementes, a composição de espécies, a distribuição e variabilidade espacial das espécies que o compõem. A informação básica foi obtida aplicando-se a técnica da emergência em amostras de solo correspondentes a 20 locais alinhados numa faixa de 14 km. A densidade de sementes nos locais de amostragem variou entre 1.173 e 44.000 sem/m2. Na totalidade, foram detectadas 33 espécies. Digitaria sanguinalis foi claramente a espécie dominante, aportando com quase 43 % do banco, seguida de Polygonum aviculare com um aporte de 15 %. As duas espécies, juntamente com Anagallis arvensis e Setaria viridis completam70 % do banco de sementes. A composição específica completa-se com um grupo de 29 espécies, os quais contribuem, cada um delas, com menos de 5%. A distribuição espacial das espécies ao longo da faixa estudada mostrou um grau de agregação variável, sendo encontrada uma correlação positiva significativa entre o tamanho do banco e a relação variância/média.

  16. Teaching Chemistry Students How To Use Patent Databases and Glean Patent Information

    Science.gov (United States)

    MacMillan, Margy; Shaw, Lawton

    2008-07-01

    Patent literature is an important source of chemical information that is often neglected by chemical educators. This paper describes an effort to teach chemistry students how to use patent databases to search for information on applied chemical technology related to the manufacture of industrial and specialty chemicals. Students in a second-year-level organic chemistry class were shown how to search patent literature as part of a group research paper assignment that involved determining the feasibility of starting an industrial chemical operation to manufacture a given industrial chemical. Students who were assigned high value or specialty chemicals were most likely to cite patent literature in their final papers. Students who were assigned plastics or bulk commodity chemicals were less likely to cite patents. It is suggested that students made choices about the usefulness of patent literature and that patents were most useful when current patents existed and provided the patent owner a competitive advantage. For plastics or commodity chemicals, manufacturing technologies tend to be mature and are well described by more accessible information sources. Suggestions are made for effective introduction of patent literature instruction into upper-level chemistry courses.

    We explore the development of probabilistic retrieval models for integrating term statistics with entity search using multiple levels of document context to improve the performance of chemical patent search. A distributed indexing model was developed to enable efficient named entity search and aggregation of term statistics at multiple levels of patent structure including individual words, sentences, claims, descriptions, abstracts, and titles. The system can be scaled to an arbitrary number of compute instances in a cloud computing environment to support concurrent indexing and query processing operations on large patent collections.

    Quinoxaline scaffold is included in a large number of therapeutic agents because of its physicochemical properties that make the difference between them and the carbono analogue, naphthalene. This review of patented products presents the quinoxaline heterocycle as part of the structural patent claims from a medicinal chemistry perspective. We centred our discussion in the various drug patent applications of the quinoxaline and its derivatives. The applications are based firstly in the specific enzyme target with very low development in the disease treatment. Only for cancer and antimicrobial agents they were specifically determined but little is mentioned in order to insight in the last development activities.

    Full Text Available El agave (Agave tequilana Weber var. azul, se le conoce comúnmente como “Agave Azul o Agave Tequilero”. La planta de agave es un producto económicamente importante de México debido a que es el ingrediente base del Tequila, el cual es una bebida popular destilada. La micropropagación es una técnica importante para la multiplicación masiva en agave y la respuesta a los reguladores de crecimiento debe considerarse en el desarrollo de cada protocolo. El objetivo del trabajo fue obtener plántulas de agave a partir del cultivo de meristemos in vitro. Se colectaron hijuelos de seis meses en plantaciones de 3 años de edad. Los meristemos se lavaron y desinfestaron con alcohol al 70% y una solución de hipoclorito al 3% por 15 minutos y se dio triple enjuague en condiciones de asepsia en la cámara de flujo laminar. Los explantes se sembraron en el medio Murashige y Skoog (MS, suplementado con 24.6 µM de AIB y 46.46 μM de Cinetina, 30 g/L de sacarosa y 8 g/L de agar para su solidificación. El medio se vertió en frascos de 100 mL de capacidad a razón de 25 mL y se esterilizó en autoclave por 15 min a 121°C. Se sembró un explante por frasco y se colocaron en la cámara de crecimiento a 27°C con 16 horas luz. La inducción de los brotes se presentó a partir de la cuarta semana posterior a la siembra. Los brotes obtenidos se multiplicaron transfiriéndose a medio MS suplementado con 0.1 mg L-1 de AIB y 46.46 μM de Cinetina.

  3. Patent border wars: defining the boundary between scientific discoveries and patentable inventions.

    Science.gov (United States)

    Holman, Christopher M

    2007-12-01

    Drawing an appropriate boundary between unpatentable natural phenomena and patentable inventions is crucial in preventing the patent laws from unduly restricting access to fundamental scientific discoveries. Some would argue that, particularly in the U.S., patents are being issued that purport to claim a novel product or process but that, in effect, encompass any practical application of a fundamental biological principle. Examples include gene patents, which Congress is considering banning, and patents relating to biological correlations and pathways, such as the patents at issue in the headline-grabbing LabCorp v. Metabolite and Ariad v. Eli Lilly litigations. In view of the mounting concern, it seems likely that Congress and/or the courts will address the issue, and perhaps substantially shift the boundary.

    2003-01-01

    A summary has been done on the most outstanding events during the history of Rio Azul sanitary landfill by consultating documents and local newspapers. The historical outline starts in 1972, when the Inter municipal Cooperative Agreement (COCIM) was created, until May 27, 2002, when a warning was issued on the possible harmful effects on health due to technological waste disposal. Likewise, the method for estimating the mass of metals deposited in the landfill is disclosed. In this landfill the mass of metals varies between 70000 and 100000 tm. Finally, some considerations on household chemical products are made and recommendations are presented to improve metal waste management. (Author) [es

    Full Text Available Investigou-se o efeito de diferentes mediadores redox (MR na remoção de cor de corantes azo e antraquinônico pelo uso de lodo granular anaeróbio sob condições mesofílicas (30ºC e termofílicas (55ºC. Comprovou-se em experimento em batelada que a adição de concentrações catalíticas de MR pode ter um efeito marcante nas taxas de descoloração do corante azo Reactive Red 2 (RR2, mas o mesmo comportamento não pode ser obtido com o corante antraquinônico Reactive Blue 5 (RB5. Entretanto, com ambos os corantes, o simples aumento da temperatura de incubação para condições termofílicas fez acelerar consideravelmente os processos de descoloração, comparados com condições mesofílicas. Por exemplo, a constante de primeira ordem "k" da redução dos corantes RR2 e RB5, foi aumentada em 6,2 e 11 vezes, respectivamente, à 55ºC quando comparado com 30ºC. Por fim, comprovou-se em experimentos de fluxo contínuo, a boa performance do tratamento termofílico na descoloração redutiva de corantes azo.The effect of different redox mediators (RM on colour removal of azo and anthraquinone dyes was investigated with anaerobic granular sludge under mesophilic (30ºC and thermophilic (55ºC conditions. Batch experiments revealed that an addition of catalytic concentrations of RM provided a remarkable effect on the decolourisation rates of the azo dye Reactive Red 2 (RR2, but the same effect could not be obtained with the anthraquinone dye Reactive Blue 5 (RB5. Nevertheless, for both dyes, the temperature increase to thermophilic conditions was an effective strategy to considerably accelerate the decolourisation process compared to mesophilic conditions. For instance, the first-order rate constant "k" of RR2 and RB5 reduction, was increased in 6.2 and 11-fold, respectively, at 55ºC in comparison with 30ºC. Such an effect of the temperature on the reductive decolourisation of azo dye was also verified in continuous flow experiments.

    Patents are exclusive rights for a limited period of time that are granted to provide an incentive for innovation and in exchange for the public disclosure of an invention. Patenting in the medical field, especially in the field of human vaccine technologies, is full of pitfalls, because the products that finally access the market are often covered by a multitude of exclusive IP rights. This commentary gives an overview on obstacles in vaccine patenting and how to overcome them, and intends to provide a patenting guideline for researchers.

  5. Revising the Complex Economics of Patent Scope

    DEFF Research Database (Denmark)

    Howells, John

    Merges and Nelson claim to have provided an empirically grounded argument that pioneer patents of 'broad' scope are used to block technological development. It is widely understood in both law and economics that they have, as they claim, faulted Kitch's 'prospect theory' of patents, a theory...... that a function of patents is to enable the coordinated development of novel technical ideas. This article is a critical review of Merges and Nelson's historical empirical evidence. I find that, first, 'broad' scope is only implicated in one of the examples cited by Merges and Nelson as supportive evidence...... - the Wright brothers' warped-wing patent; second, that strict development block, defined as the prevention, or retardation of the development of technology understood to be capable of useful development, was not illustrated by any of their examples. Therefore I conclude that their general thesis...

    Full Text Available An effective knowledge transfer between research institutions and industry is a significant bottleneck in the national innovation system. CR adopted in recent years a series of systemic measures aimed to stimulate the orientation of the R&D organizations towards the generation of knowledge directly applicable in the innovation process and more generally to improve the collaboration of the R&D establishment with the industry. In the majority of programs supporting the applied research patents and industrial designs and utility models are among the anticipated results. The Methodology of the evaluation of R&D organizations implemented in the second half of the last decade brought financial bonuses for the creation of the results in the category of industrial property. Despite of this stimulus CR lags behind the technologically advanced EU countries in the patent activities. The topic of this article is a comparison of the protection of the industrial property rights in the Czech higher education institutions and governmental R&D institutions with selected EU countries. We make use of a couple of quantitative indicators to assess the quality and the technological and the commercial potential of the produced industrial property. Despite a dynamic growth of the patent applications in the CR the number of patent applications relative to the country size is far below the EU-15 average. The Czech research organizations contribute to a higher extent to the number of patent applications then do the analogous institutions in EU-15 countries where the majority of patent applications come from the industrial sphere. The Czech research organizations mainly limit the patent rights to the Czech Republic whereas in the EU-15 countries the opposite is preponderant and only a small fraction of patent applications remains limited to the national environment. Thus the majority of the Czech patents created by research organizations cannot be commercialized on the

    Single technology companies (STCs) are defined in this thesis as companies that (a) have the fundamental rights to a new technology, (b) have development of that technology as their core competence, (c) seek to exploit that technology primarily by licensing the patent rights, and (d) are driven primarily by 'technology push'. These factors often result in much of the value of the STC residing in its patent portfolio. This in turn may place significant - and often conflicting - ...

  11. Competition policy in patent cases and antitrust.

    Science.gov (United States)

    Sobel, Gerald

    2003-01-01

    The article that follows examines the competition policy reflected in the decisions of the Court of Appeals for the Federal Circuit in its patent cases. The court's views on this subject have been manifested most plainly in decisions that have transformed the law concerning infringement under the doctrine of equivalents and claim construction. In both categories, the court narrowed patent scope by reason of its desire to protect competitors. The article argues that the court's premise in prescribing narrower claim scope reflected an incomplete view of competition policy. The court's analysis overlooked the benefits to competition provided by patents, which stimulate inventions and their development. The article traces the development of antitrust jurisprudence and demonstrates how respect for the contribution of patents to competition and skepticism of free-riding has evolved, particularly beginning in the 1970s. The article draws a parallel between the Court's reasoning about competition policy, on the one hand, and the rejected views of Justices Hugo Black and William O. Douglas and abandoned patent-antitrust jurisprudence, on the other. The Federal Circuit's decision in Festo Corp. v. Shoketsu Kinzoku Kogyo Kabushiki Co., Ltd., 234 F.3d 558 (Fed. Cir. 2000), on the subject of equivalents is considered in the paper. In that decision, the majority adopted a new rule that completely barred infringement under the doctrine of equivalents of any claim limitation where, in prosecution, there had been a narrowing amendment relating to patentability. In the past, prosecution estoppel foreclosing equivalents had been subject to a "flexible bar," which, in some circumstances, allowed for equivalence notwithstanding such an amendment. The article points out that because almost all patents are amended during prosecution, the effect would be to allow widespread copying of patented inventions by trivial modifications of any narrowed claim limitation. The incentive to innovate

Sin embargo, se observan efectos socioambientales negativos. Desde 2003 se han estudiado las condiciones del cultivo y su expansión, así como alternativas posibles. Los resultados muestran un crecimiento acelerado desde su introducción, a mitad de la década de 1990. Se destaca una concentración de propietarios privados y a través de contratos. Si bien sembrar esta planta puede ser redituable, las tendencias cíclicas de sobreproducción y escasez han originado una falta de incentivos para hacerlo y un deterioro de la capacidad productiva. Se discuten las perspectivas del avance agropecuario basado en el cultivo del agave azul, y se ofrecen algunas recomendaciones para fomentar la sustentabilidad de su sistema de producción comercial.

  18. Can patents prohibit research? On the social epistemology of patenting and licensing in science.

    Science.gov (United States)

    Biddle, Justin B

    2014-03-01

    A topic of growing importance within philosophy of science is the epistemic implications of the organization of research. This paper identifies a promising approach to social epistemology--nonideal systems design--and uses it to examine one important aspect of the organization of research, namely the system of patenting and licensing and its role in structuring the production and dissemination of knowledge. The primary justification of patenting in science and technology is consequentialist in nature. Patenting should incentivize research and thereby promote the development of knowledge, which in turn facilitates social progress. Some have disputed this argument, maintaining that patenting actually inhibits knowledge production. In this paper, I make a stronger argument; in some areas of research in the US--in particular, research on GM seeds--patents and patent licenses can be, and are in fact being, used to prohibit some research. I discuss three potential solutions to this problem: voluntary agreements, eliminating patents, and a research exemption. I argue against eliminating patents, and I show that while voluntary agreements and a research exemption could be helpful, they do not sufficiently address the problems of access that are discussed here. More extensive changes in the organization of research are necessary.

  19. The diffusion of patented oil and gas technology with environmental uses: A forward patent citation analysis

    Duch-Brown, Néstor; Costa-Campi, María Teresa

    2015-01-01

    Relevant advances in the mitigation of environmental impact could be obtained by the appropriate diffusion of existing environmental technologies. In this paper, we look at the diffusion of knowledge related to environmental technologies developed within the oil and gas industry. To assess knowledge spillovers from oil and gas inventions as a measure of technology diffusion, we rely on forward patent citations methodology. Results show that there is a strong likelihood that the citing patent will be eventually linked to environmental technologies if the original oil and gas invention has already environmental uses. Moreover, both intra and intersectoral spillovers produce a “turnabout” effect, meaning that citing patents show the opposite quality level of the cited patent. Our results support the idea that more sector-specific environmental policies, with an emphasis on diffusion, would significantly improve the use of environmental technologies developed within the oil and gas industry. -- Highlights: •Knowledge spillovers from oil and gas inventions are of an intrasectoral nature. •Environmental uses in original patents diffuse to patents with environmental uses. •The “turnabout” effect converts low quality patents into high quality citing patents. •Diffusion of oil and gas inventions need more ad hoc instruments

  1. Biological diversity in the patent system.

    Directory of Open Access Journals (Sweden)

    Paul Oldham

    Full Text Available Biological diversity in the patent system is an enduring focus of controversy but empirical analysis of the presence of biodiversity in the patent system has been limited. To address this problem we text mined 11 million patent documents for 6 million Latin species names from the Global Names Index (GNI established by the Global Biodiversity Information Facility (GBIF and Encyclopedia of Life (EOL. We identified 76,274 full Latin species names from 23,882 genera in 767,955 patent documents. 25,595 species appeared in the claims section of 136,880 patent documents. This reveals that human innovative activity involving biodiversity in the patent system focuses on approximately 4% of taxonomically described species and between 0.8-1% of predicted global species. In this article we identify the major features of the patent landscape for biological diversity by focusing on key areas including pharmaceuticals, neglected diseases, traditional medicines, genetic engineering, foods, biocides, marine genetic resources and Antarctica. We conclude that the narrow focus of human innovative activity and ownership of genetic resources is unlikely to be in the long term interest of humanity. We argue that a broader spectrum of biodiversity needs to be opened up to research and development based on the principles of equitable benefit-sharing, respect for the objectives of the Convention on Biological Diversity, human rights and ethics. Finally, we argue that alternative models of innovation, such as open source and commons models, are required to open up biodiversity for research that addresses actual and neglected areas of human need. The research aims to inform the implementation of the 2010 Nagoya Protocol on Access to Genetic Resources and the Equitable Sharing of Benefits Arising from their Utilization and international debates directed to the governance of genetic resources. Our research also aims to inform debates under the Intergovernmental Committee on

    2017-09-01

    Full Text Available The article is devoted to the analysis and the choice of the priorities in technology development and, particularly, to the use of patent landscaping as a tool for the study of technology trends. Currently, patent activity indicators are often used for technology foresight and for competitive intelligence as well. Nevertheless, causal relationship between these indicators, on the one hand, and strategic and tactical decisions in the sphere of technological development on meso- and microeconomic level, on the other hand, are not adequately investigated to solve practical tasks. The goal of the work is to systemize the challenges of technology trends analysis, which could be effectively solved on the base of patent landscape analysis. The article analyses the patent landscaping methodology and tools, as well as their use for evaluating the current competitive environment and technology foresight. The authors formulated the generalized classification for the criteria of promising technologies for a selected region. To assess the compliance of a technology with these criteria, we propose a system of corresponding indicators of patenting activity. Using the proposed methodology, we have analysed the patent landscape to select promising technologies for the Sverdlovsk region. The research confirmed the hypothesis of the patent landscapes performance in evaluating such technology indicators as stages of the life cycle stage, universality (applicability in different industries, pace of worldwide development, innovations and science availability in the region and potential possibilities for scientific collaboration with international research institutions and universities. The results of the research may be useful to the wide audience, including representatives small and medium enterprises, large companies and regional authorities for the tasks concerned with the technology trends analysis and technology strategy design

    "Neglected Tropical Diseases" (NTDs) affect millions of people in Africa, Asia and South America. The two primary ways of strategic interventions are "preventive chemotherapy and transmission control" (PCT), and "innovative and intensified disease management" (IDM). In the last 5 years, phenomenal progress has been achieved. However, it is crucial to intensify research effort into NTDs, because of the emerging drug resistance. According to the World Health Organization (WHO), the term NTDs covers 17 diseases, namely buruli ulcer, Chagas disease, dengue, dracunculiasis, echinococcosis, trematodiasis, human African trypanosomiasis, leishmaniasis, leprosy, lymphatic filariasis, onchocerciasis, rabies, schistosomiasis, soil-transmitted helminthes, taeniasis, trachoma, and yaws. The aim of this study is to map out research and development (R&D) landscape through patent analysis of these identified NTDs. To achieve this, analysis and evaluation have been conducted on patenting trends, current legal status of patent families, priority countries by earliest priority years and their assignee types, technological fields of patent families over time, and original and current patent assignees. Patent families were extracted from Patseer, an international database of patents from over 100 patent issuing authorities worldwide. Evaluation of the patents was carried out using the combination of different search terms related to each identified NTD. In this paper, a total number of 12,350 patent families were analyzed. The main countries with sources of inventions were identified to be the United States (US) and China. The main technological fields covered by NTDs patent landscape are pharmaceuticals, biotechnology, organic fine chemistry, analysis of biological materials, basic materials chemistry, and medical technology. Governmental institutions and universities are the primary original assignees. Among the NTDs, leishmaniasis, dengue, and rabies received the highest number of

    Chapman, Audrey R

    2009-09-01

    Just as human embryonic stem cell research has generated controversy about the uses of human embryos for research and therapeutic applications, human embryonic stem cell patents raise fundamental ethical issues. The United States Patent and Trademark Office has granted foundational patents, including a composition of matter (or product) patent to the Wisconsin Alumni Research Foundation (WARF), the University of Wisconsin-Madison's intellectual property office. In contrast, the European Patent Office rejected the same WARF patent application for ethical reasons. This article assesses the appropriateness of these patents placing the discussion in the context of the deontological and consequentialist ethical issues related to human embryonic stem cell patenting. It advocates for a patent system that explicitly takes ethical factors into account and explores options for new types of intellectual property arrangements consistent with ethical concerns.

    'Full text:' A patent application is generally filed shortly after completion of research and development; therefore, patent filing statistics provide insight into the state of innovation of a technology. A study has been conducted on fuel cell patenting activity in Canada. This study examines fuel cell patenting trends between 1989-2003 and specific activity in 2001, identifies the major players in the Canadian fuel cell industry, and examines the patent landscape by fuel cell technology. Our results show that historically, Canadians have been leaders at home and abroad in fuel cell innovation. However, Canadians have recently fallen behind in protecting their patent rights at home, and now rank fourth behind German, American and Japanese fuel cell patent filers in the Canadian patent office. However, our data also shows that a significant number of new Canadian entities have emerged and have been very active filing new patent applications. These new entities as well as established Canadian companies are examined in detail. (author)

    2000-12-12

    We present the application of a new knowledge visualization tool, VxInsight, to the mapping and analysis of patent databases. Patent data are mined and placed in a database, relationships between the patents are identified, primarily using the citation and classification structures, then the patents are clustered using a proprietary force-directed placement algorithm. Related patents cluster together to produce a 3-D landscape view of the tens of thousands of patents. The user can navigate the landscape by zooming into or out of regions of interest. Querying the underlying database places a colored marker on each patent matching the query. Automatically generated labels, showing landscape content, update continually upon zooming. Optionally, citation links between patents may be shown on the landscape. The combination of these features enables powerful analyses of patent databases.

The patent offices of the United States (USA), People's Republic of China (PRC), Japan, and South Korea have published the largest number of nanotechnology patent applications, and experienced significant but different growth rates after 2000. In most repositories, the largest numbers of nanotechnology patent applications originated from their own countries/regions, indicating a significant 'home advantage.' The top applicant institutions are from different sectors in different countries (e.g., from industry in the US and Canada patent offices, and from academe or government agencies at the PRC office). As compared to 2000, the year before the establishment of the US National Nanotechnology Initiative (NNI), numerous new invention topics appeared in 2008, in all 15 patent repositories. This is more pronounced in the USA and PRC. Patent families have increased among the 15 patent offices, particularly after 2005. Overlapping patent applications increased from none in 1991 to about 4% in 2000 and to about 27% in 2008. The largest share of equivalent nanotechnology patent applications (1,258) between two repositories was identified between the US and Japan patent offices.

    The protection provided by patents on medicines has a limited duration. The expiry of patents expiration allows copies of the drugs to be released, competing with original. At first, they were identical to the original, known as generic drugs, but in recent years, due to the marketing of biological therapies and the expiry of many of their patents, biosimilar drugs have also emerged. These are not exact copies of the original, but, like generic drugs, biosimilar drugs have to demonstrate equivalence to the reference drugs in quality, safety and efficacy. Nevertheless, despite their importance and contribution to sustainability of health system, doctors are sometimes unaware of differences between them, and their impact in terms of clinical and economic effects. An attempt is made to review and clarify certain aspects often unknown by physicians, despite their involvement in their use. Copyright © 2015 SECA. Published by Elsevier Espana.

  16. Patents, antibiotics, and autarky in Spain.

    Science.gov (United States)

    Romero De Pablos, Ana

    2014-01-01

    Patents on antibiotics were introduced in Spain in 1949. Preliminary research reveals diversification in the types of antibiotics: patents relating to penicillin were followed by those relating to streptomycin, erythromycin and tetracycline. There was also diversification in the firms that applied for patents: while Merck & Co. Incorporated and Schenley Industries Inc. were the main partners with Spanish antibiotics manufacturers in the late 1940s, this industrial space also included many others, such as Eli Lilly & Company, Abbott Laboratories, Chas. Pfizer & Co. Incorporated, and American Cyanamid Company in the mid-1970s. The introduction of these drugs in Spain adds new elements to a re-evaluation of the autarkic politics of the early years of the Franco dictatorship.

    The aim of the article is to present a trend in patent filings for application of nanotechnology to the automobile sector across the world, using the keyword-based patent search. Overviews of the patents related to nano technology in the automobile industry have been provided. The current work has started from the worldwide patent search to find the patents on nanotechnology in the automobile industry and classify the patents according to the various parts of an automobile to which they are related and the solutions which they are providing. In the next step various graphs have been produced to get an insight into various trends. In next step, analysis of patents in various classifications, have been performed. The trends shown in graphs provide the quantitative analysis whereas; the qualitative analysis has been done in another section. The classifications of patents based on the solution they provide have been performed by reading the claims, titles, abstract and full texts separately. Patentability of nano technology inventions have been discussed in a view to give an idea of requirements and statutory bars to the patentability of nanotechnology inventions. Another objective of the current work is to suggest appropriate framework for the companies regarding use of nano technology in the automobile industry and a suggestive strategy for patenting of the inventions related to the same. For example, US Patent, with patent number US2008-019426A1 discusses the invention related to Lubricant composition. This patent has been studied and classified to fall under classification of automobile parts. After studying this patent, it is deduced that, the problem of friction in engine is being solved by this patent. One classification is the "automobile part" based while other is the basis of "problem being solved". Hence, two classifications, namely reduction in friction and engine were created. Similarly, after studying all the patents, a similar matrix has been created.

    Patents and patent portfolios are gaining attention in the last decades, from the called 'pro-patent era' to the recent billionaire transactions involving patent portfolios. The field is growing in importance, both theoretically and practically and despite having substantial literature on new product development portfolio management, we have not found an article relating this theory to patent portfolios. Areas covered: The paper develops a systematic literature review on patent portfolio management to organize the evolution and tendencies of patent portfolio management, highlighting distinctive features of patent portfolio management. Interview with IP manager of three life sciences companies, including a leading multinational group provided relevant information about patent portfolio management. Expert opinion: Based on the systematic literature review on portfolio management, more specifically, on new product development portfolio theory, and interview the paper proposes the paper proposes a reference model to manage patent portfolios. The model comprises four stages aligned with the three goals of the NPD portfolio management: 1 - Linking strategy of the Company's NPD Portfolio to Patent Portfolio; 2 - Balancing the portfolio in buckets; 3 - Patent Valuation (maximizing valuation); 4 - Regularly reviewing the patent portfolio.

  19. Cross-Border Patent Disputes: Unified Patent Court or International Commercial Arbitration?

    Directory of Open Access Journals (Sweden)

    Ana Alba Betancourt

    2016-04-01

    Full Text Available Currently, the enforcement of a patent that is registered in several countries involves the risk of getting different and conflicting decisions from the national courts. In 2013, 25 European countries entered in an agreement that aims to homogenise the patent system by creating the European patent with unitary effect and a Unified Patent Court (UPC. This article focuses on the UPC, which aims to have a single court proceeding for cross-border patent conflicts. Does the UPC system represent an advantage compared to the current litigation system? The paper argues that it does and explores what it considers to be the two main advantages of a UPC over the current system of cross-border litigation of patents: the ability to drag several conflicts to a single procedure and the neutrality of the decision makers. These advantages are consequently compared to the characteristics of arbitration. Then, an explanation is provided with regards to how the UPC system is going to work in terms of jurisdiction, preliminary injunctions, the choice of law and enforcement of decisions, comparing those same procedural aspects to arbitration. The article finds that arbitration involves many of the same advantages (as compared to the UPC and that the procedural issues studied in both means are, so too, similar. Therefore, arbitration represents a viable alternative to the UPC when it comes to reducing the risks in solving cross-border patent conflicts.

  20. Patent Keyword Extraction Algorithm Based on Distributed Representation for Patent Classification

    Full Text Available Many text mining tasks such as text retrieval, text summarization, and text comparisons depend on the extraction of representative keywords from the main text. Most existing keyword extraction algorithms are based on discrete bag-of-words type of word representation of the text. In this paper, we propose a patent keyword extraction algorithm (PKEA based on the distributed Skip-gram model for patent classification. We also develop a set of quantitative performance measures for keyword extraction evaluation based on information gain and cross-validation, based on Support Vector Machine (SVM classification, which are valuable when human-annotated keywords are not available. We used a standard benchmark dataset and a homemade patent dataset to evaluate the performance of PKEA. Our patent dataset includes 2500 patents from five distinct technological fields related to autonomous cars (GPS systems, lidar systems, object recognition systems, radar systems, and vehicle control systems. We compared our method with Frequency, Term Frequency-Inverse Document Frequency (TF-IDF, TextRank and Rapid Automatic Keyword Extraction (RAKE. The experimental results show that our proposed algorithm provides a promising way to extract keywords from patent texts for patent classification.

    2018-04-01

    This article examines the shifts in the material ordering of inventions in patent law organization and their effects on the meaning and scope of inventions as intellectual property. Formats and media are constitutive of the establishment and stabilization of inventions as objects of intellectual property. Modern patent law's materiality had been dominated by paper documents but ever more consists of digital images, files, and networked data. The article traces and analyzes such effects of digital media on the meaning of intellectual/intangible property and argues that inventions increasingly matter as digital data in the legal realm.

    Full Text Available As empresas se utilizam de estratégias e atitudes para chegar a um determinado objetivo, observando os pontos fortes e fracos do ambiente interno e externo da organização. Assim, têm-se a teoria do trade-off (valorXcusto no qual as empresas sempre optam por um de dois caminhos: agregar valor ao produto para cobrar mais, ou o cobrar menor preço com um produto menos diferenciado. Hoje, emerge no mundo científico um novo paradigma, a estratégia do oceano azul, a qual afirma que é possível as empresas optarem, de uma só vez, pela diferenciação e pela liderança em preços. Este trabalho visa verificar a relação entre a estratégia do oceano azul com a adotada por uma empresa de serviços de pesquisa e intermediação de compras de mantimentos, que concorre com supermercados, ofertando os mesmos produtos, porém, de forma inovadora com este tipo de comercialização na cidade de Campina Grande-PB, através da compra pela internet. Trata-se de um estudo de caso aplicado aos principais supermercados do município e para tratamento dos dados utilizou-se da abordagem quali-quantitativa. Foi analisada a percepção do cliente e feito a matriz de avaliação de valor, tanto do setor de atuação quanto da empresa estudada. Concluiu-se, que a estratégia adotada está alinhada com a estratégia de oceano azul, pois, igualmente aos supermercados, a empresa estudada supre a necessidade dos clientes, todavia, sem utilizar estoques, com entrega em domicílio e atendimento personalizado, tudo isto sem acrescentar maiores custos ao consumidor final, liderando em preços ao passo que se diferencia da concorrência.

    Directory of Open Access Journals (Sweden)

    Haim V. Levy

    2012-01-01

    Full Text Available The transformation of innovation into commercial value depends primarily on appropriate protection of the intellectual property, usually by patents, and efficient pathway(s of its transferability as well as the transfer of the protected knowledge. The key features of patents, from an economic perspective, are that they encompass new knowledge and confer monopoly rights to the owner. The exclusiveness of patent rights is generally conceived as a necessary mechanism to ensure further innovation, stimulate advanced research and facilitate efficient market transactions with patent rights. The patent holder can transfer the technology embodied by way of granting to others a license to use the patented invention in return for a share of the revenues, usually royalties. Patent rights transferability has been proven to be efficient and profitable to the industry as well as beneficial to the welfare of society. The economic and practical perspectives of the transferability and commercialization of patent rights are discussed.

    Patent collections contain an important amount of medical-related knowledge, but existing tools were reported to lack of useful functionalities. We present here the development of TWINC, an advanced search engine dedicated to patent retrieval in the domain of health and life sciences. Our tool embeds two search modes: an ad hoc search to retrieve relevant patents given a short query and a related patent search to retrieve similar patents given a patent. Both search modes rely on tuning experiments performed during several patent retrieval competitions. Moreover, TWINC is enhanced with interactive modules, such as chemical query expansion, which is of prior importance to cope with various ways of naming biomedical entities. While the related patent search showed promising performances, the ad-hoc search resulted in fairly contrasted results. Nonetheless, TWINC performed well during the Chemathlon task of the PatOlympics competition and experts appreciated its usability.

  15. Annotated chemical patent corpus: a gold standard for text mining.

    Directory of Open Access Journals (Sweden)

    Saber A Akhondi

    Full Text Available Exploring the chemical and biological space covered by patent applications is crucial in early-stage medicinal chemistry activities. Patent analysis can provide understanding of compound prior art, novelty checking, validation of biological assays, and identification of new starting points for chemical exploration. Extracting chemical and biological entities from patents through manual extraction by expert curators can take substantial amount of time and resources. Text mining methods can help to ease this process. To validate the performance of such methods, a manually annotated patent corpus is essential. In this study we have produced a large gold standard chemical patent corpus. We developed annotation guidelines and selected 200 full patents from the World Intellectual Property Organization, United States Patent and Trademark Office, and European Patent Office. The patents were pre-annotated automatically and made available to four independent annotator groups each consisting of two to ten annotators. The annotators marked chemicals in different subclasses, diseases, targets, and modes of action. Spelling mistakes and spurious line break due to optical character recognition errors were also annotated. A subset of 47 patents was annotated by at least three annotator groups, from which harmonized annotations and inter-annotator agreement scores were derived. One group annotated the full set.

    NARCIS (Netherlands)

    Ziegler, Nicole; Gassmann, Oliver; Friesike, Sascha

    2013-01-01

    Within the trend of increasing patent commercialisation and open innovation, a recent phenomenon where firms give away their patents free of charge can be observed. This seems contradictory to the original intention of the patent system (enabling firms to create temporary monopolies to appropriate

    1995-02-01

    Full Text Available Fish meal production characteristics and treatment are described, together with a detailed explanation of the international regulations for its maritime transport, as well as of the requirements for its stabilization to avoid its spontaneous combustion. Experience with this kind of transport, as well as Intensive research carried out over several years, has shown that the high fat content in several kinds of fish and the environmental humidity and temperature have a great influence and transform this kind of cargo into dangerous goods. Knowledge of proper stowage and cargo distribution in the holds greatly decreases the dangers during maritime transport. Good transport practice and stabilization of the meal with antioxidants together with the conclusions reached after research, make maritime transport of these cargoes safer.

    Se detallan las características de la fabricación y tratamiento de la harina de pescado azul, junto con un amplio desarrollo de las disposiciones internacionales para su transporte por vía marítima, así como la necesidad de estabilizar la harina de pescado para evitar la combustión espontánea. La experiencia en este transporte, además de las investigaciones realizadas durante varios años, ha puesto de manifiesto que el contenido de grasa en el pescado azul, la humedad y la temperatura, tienen una gran influencia y convierten a estos cargamentos en mercancías peligrosas. El conocimiento de una buena estiba o distribución de la carga dentro de las bodegas reduce considerablemente la peligrosidad en su transporte por mar. Esta práctica en el transporte y su estabilización con antioxidantes, junto con las conclusiones aportadas en la investigación, determinan un viaje más seguro en el transporte de estas mercancías.

  3. Visibilidad y enunciabilidad en la larga duración de la violencia política: La sombra azul de Sergio Schmucler

    Directory of Open Access Journals (Sweden)

    Graciana Vásquez Villanueva

    2015-06-01

    Full Text Available Una historia de vida, eje fundamental de un film, es la discursividad que hemos indagado para percibir sentidos nuevos en la relación cine, memoria y violencia en la zona amplia de los discursos producidos sobre el terrorismo de estado en Argentina. La sombra azul, con guión y dirección de Sergio Schmucler, irrumpe para desbaratar conciencias. Nuestro trabajo, filiado en el Análisis del Discurso, se ha detenido en la indagación de tres dispositivos: las visibilidades, las enunciabilidades y las temporalidades, superpuestas, fragmentarias a veces, otras omnipresentes, deslizadas en la larga duración de una memoria social. Estos dispositivos, elaborados por Foucault para blandir discursividades exasperantes de órdenes impuestos, constituyen un camino privilegiado para llegar, a través de su desgranamiento, a una verdad intolerable forjada en este film. En La sombra azul la larga duración de la violencia de estado, la impunidad de los represores durante la democracia y, fundamentalmente, un sobreviviente —a la tortura, la prisión, el exilio, perteneciente a la fuerza policial de una de las provincias más castigadas por la dictadura— son cincelados, en la heteroglosia, en el diálogo y en el antagonismo, con otras voces. Este sobreviviente, devenido en re-viviente señala cómo un marco ético, capaz de valorar la tragedia humana, lo erige en un don para dotar de verdad, para esclarecer a una sociedad que, en muchos espacios, aún permanece en sombra. Este recorrido discursivo señala cómo, desde la indecibilidad original de un sujeto doliente, irrumpen visibilidades y enunciabilidades capaces de decir verdad y así proseguir con una memoria que nunca cesa.

    The Furna Azul Migmatite is a ∼10 km{sup 2} complex located in Pontes e Lacerda city, Mato Grosso, Brazil. It belongs to Paragua Terrane, limit with Rio Alegre Terrane, southeast of San Ignacio Province, in Amazon Craton. It consists of transitional metatexites with amphibolite enclaves and dioritic injections. The rocks were divided in residuum rich and leucosome rich; both have three deformation phases marked by folded stromatic layers affected by spaced foliation and metamorphosed in amphibolite facies, represented by garnet, biotite, sillimanite, and by the clinopyroxene in the enclaves. The metamorphic retrograde to greenschist is marked by formation of chlorite, muscovite and prehnite. Residuum-rich metatexites show higher CaO and Na{sub 2}O contents, separating them from K{sub 2}O, Ba and Rb enriched transitional metatexites. U-Pb on zircon and Sm-Nd whole-rocks dating indicates that the residuum-rich metatexite crystallized at 1436 ± 11 Ma, with a T{sub DM} age of 1.90 Ga and ε{sub Nd(1.43)} of -0.54, whereas the dioritic injection crystallized at 1341,7 ± 17 Ma with a T{sub DM} age of 1.47 Ga and ε{sub Nd(1.34)} of 3.39. These results indicate that the Furna Azul Migmatite protolith was formed during the San Ignacio Orogeny and was reworked during the same orogeny, as basement for collisional to post-magmatic granites from Pensamiento Intrusive Suite.

  5. Patenting of university and non-university public research organisations in Germany: evidence from patent applications for medical research results.

    Directory of Open Access Journals (Sweden)

    Peter Tinnemann

    Full Text Available BACKGROUND: Patents are one of the most important forms of intellectual property. They grant a time-limited exclusivity on the use of an invention allowing the recuperation of research costs. The use of patents is fiercely debated for medical innovation and especially controversial for publicly funded research, where the patent holder is an institution accountable to public interest. Despite this controversy, for the situation in Germany almost no empirical information exists. The purpose of this study is to examine the amount, types and trends of patent applications for health products submitted by German public research organisations. METHODS/PRINCIPAL FINDINGS: We conducted a systematic search for patent documents using the publicly accessible database search interface of the German Patent and Trademark Office. We defined keywords and search criteria and developed search patterns for the database request. We retrieved documents with application date between 1988 and 2006 and processed the collected data stepwise to compile the most relevant documents in patent families for further analysis. We developed a rationale and present individual steps of a systematic method to request and process patent data from a publicly accessible database. We retrieved and processed 10194 patent documents. Out of these, we identified 1772 relevant patent families, applied for by 193 different universities and non-university public research organisations. 827 (47% of these patent families contained granted patents. The number of patent applications submitted by universities and university-affiliated institutions more than tripled since the introduction of legal reforms in 2002, constituting almost half of all patent applications and accounting for most of the post-reform increase. Patenting of most non-university public research organisations remained stable. CONCLUSIONS: We search, process and analyse patent applications from publicly accessible databases

  6. Ethical limitations in patenting biotechnological inventions.

    Science.gov (United States)

    Lugagnani, V

    1999-01-01

    In order to connect ethical considerations with practical limits to patentability, the moral judgement should possibly move from the exploitation of the invention to the nature and/or objectives of Research and Development (R&D) projects which have produced it: in other words, it appears quite reasonable and logical that Society is not rewarding unethical R&D activities by granting intellectual property rights. As far as biotechnology R&D is concerned, ethical guidance can be derived from the 1996 Council of EuropeOs OConvention for the protection of human rights and dignity of the human being with regard to the application of biology and medicineO, whose Chapter V - Scientific research - provides guidelines on: i. protection of persons undergoing research (e.g. informed consent); ii. protection of persons not able to consent to research; iii. research on embryos in vitro. As far as the specific point of patenting biotechnology inventions is concerned, the four exclusions prescribed by Directive 98/44/EC (i.e. human cloning, human germ-line gene therapy, use of human embryos for commercial purposes, unjustified animal suffering for medical purposes) are all we have in Europe in terms of ethical guidance to patentability. In Italy, in particular, we certainly need far more comprehensive legislation, expressing SocietyOs demand to provide ethical control of modern biotechnology. However it is quite difficult to claim that ethical concerns are being raised by currently awarded biotechnology patents related to living organisms and material thereof; they largely deal with the results of genomic R&D, purposely and usefully oriented toward improving health-care and agri-food processes, products and services. ONo patents on lifeOO can be an appealing slogan of militants against modern biotechnology, but it is far too much of an over-simplified abstraction to become the Eleventh Commandment our Society.

  7. A Patent Analysis for Sustainable Technology Management

    Directory of Open Access Journals (Sweden)

    Junhyeog Choi

    2016-07-01

    Full Text Available Technology analysis (TA is an important issue in the management of technology. Most R&D (Research & Development policies have depended on diverse TA results. Traditional TA results have been obtained through qualitative approaches such as the Delphi expert survey, scenario analysis, or technology road mapping. Although they are representative methods for TA, they are not stable because their results are dependent on the experts’ knowledge and subjective experience. To solve this problem, recently many studies on TA have been focused on quantitative approaches, such as patent analysis. A patent document has diverse information of developed technologies, and thus, patent is one form of objective data for TA. In addition, sustainable technology has been a big issue in the TA fields, because most companies have their technological competitiveness through the sustainable technology. Sustainable technology is a technology keeping the technological superiority of a company. So a country as well as a company should consider sustainable technology for technological competition and continuous economic growth. Also it is important to manage sustainable technology in a given technology domain. In this paper, we propose a new patent analysis approach based on statistical analysis for the management of sustainable technology (MOST. Our proposed methodology for the MOST is to extract a technological structure and relationship for knowing the sustainable technology. To do this, we develop a hierarchical diagram of technology for finding the causal relationships among technological keywords of a given domain. The aim of the paper is to select the sustainable technology and to create the hierarchical technology paths to sustainable technology for the MOST. This contributes to planning R&D strategy for the sustainability of a company. To show how the methodology can be applied to real problem, we perform a case study using retrieved patent documents related to

    2011-06-01

    Full Text Available Valuation of intangible assets is a complex topic where traditional methodologies are not always successful. Nevertheless, intangible assets, like patents, have become of great importance to companies, as their value is considered to be relevant economic and strategic information, so it is necessary to evaluate firms’ patent portfolios. The present research introduces an extended goal programming model to calculate the relative importance of the patents of companies in a patent pool. This information may be useful for patent valuation as well as for management purposes. The proposed multicriteria methodology has been applied to the 19 companies in the MPEG2 patent pool, with a total of 770 valid patents, using 7 criteria to obtain a composite measure of the relative position of the firms in the patent pool.RESUMENLa valoración de activos intangibles constituye un área compleja donde los métodos tradicionales no siempre obtienen buenos resultados. Sin embargo, los activos intangibles, entre ellos las patentes, han ganado importancia en las empresas, de forma que el cálculo de su valor se ha convertido en una cuestión estratégica en muchos casos. Este hecho requiere que las empresas valoren la cartera de patentes en su conjunto. La presente investigación presenta un modelo extendido de programación por metas y su aplicación para el cálculo de la importancia relativa de las patentes. Este modelo puede resultar importante tanto para la valoración de las patentes como para la gestión empresarial. La metodología multicriterio propuesta ha sido aplicado a 19 empresas en el sector de las patentes del formato MPEG2, con un total de 770 patentes válidas, y utilizando 7 criterios con el objetivo de obtener una medida compuesta de la posición relativa de las empresas en el conjunto de patentes.

  15. Patent Value: A Business Perspective for Technology Startups

    Directory of Open Access Journals (Sweden)

    Angela de Wilton

    2011-12-01

    Full Text Available In the last year, news headlines have highlighted record patent infringement settlements, multibillion dollar auctions of large corporate patent portfolios, and ongoing patent battles between key technology industry players. Despite this acknowledgment of the significant value of patents for large corporations, many small technology companies are understandably more focused on the near-term costs of obtaining a patent rather than future value. Costs may seem prohibitive to an early stage technology startup. Some software startups question whether patents are relevant to their business. In practice, effective intellectual property (IP strategy and management is dependent on many factors, such as technology or industry sector, size and maturity of the business, technology lifecycle, and the business and market environment. IP strategy must be aligned to business strategy from the outset. By considering IP in the broader context of the overall business plan and the competitive environment, opportunities for generating increased return on R&D investment and added business value through patents or other forms of IP can be recognized early on. This approach ensures that a decision about whether or not to patent is driven by business reasons rather than budget constraints. This article examines the costs and benefits of patents from the perspective of early-stage technology startups and growing businesses, and it provides some general guidance on best practices for developing an IP and patent activity plan and for building a patent portfolio that appropriately supports business objectives.

  17. The shadow of inequitable conduct in the US patent application.

    Inequitable conduct regarding any single claim can render the entire patent unenforceable and further damage other related patents and applications in the assignee's patent portfolio. The adverse impact of inequitable conduct significantly became a litigation strategy. The US Federal Circuit (CAFC) observed that inequitable conduct as a patent litigation strategy had become a plague and thus tightened the standard for finding inequitable conduct in a case with full court judges. However, under the shadow of previous adverse impact of inequitable conduct, patent applicants may still submit many marginal related references. This study demonstrates that an applicant even prepared an information disclosure statement (IDS) as many as 50 pages. Actually, under the new standard, inequitable conduct would not further produce significant impact in the US patent system. Thus, a patent applicant need not submit marginal references but should distinguish the prior art from the current application, especially for those listed in the IDS, to avoid the novelty rejection.

  18. The impact of effective patents on future innovations in nanomedicine.

    Bosetti, Rita; Vereeck, Lode

    2012-03-01

    The success of nanomedicine is dependent upon an effective protection of IP rights. Unfortunately, the US nanomedicine patent system is dysfunctional because long R&D procedures as well as the patent pendency are insufficiently taken into account. This could be solved by changing the patent-protection starting point and increasing the capacity of the US PTO. The nanotechnology industry also suffers from overlapping patents. This could be avoided by improving the expertise of the PTO, using a more accurate definition of nanotechnology and devising a generally accepted nomenclature that enhances prior-art searches. To avoid disputes, inference practices and strategic patenting can be used. In the case of a dispute, parties can fall back on re-examination, cross-licensing and patent litigation. Cross-licensing agreements are recommended since they allows parties to access technology, create synergies and exclude third-party competitors. Solving the patent problems in the nanotechnology industry is a necessary step for future success.

  19. Advances in CO2 capture technology: A patent review

    2013-01-01

    Highlights: ► Timely updates on carbon capture technologies: More than 1000 patents on solvent, sorbent, and membrane. ► More patents on solvent and sorbent compared to membrane. ► Environmental and health concerns exist regarding carbon capture technologies. -- Abstract: Carbon dioxide (CO 2 ) emissions are believed to be a major contributor to global warming. As a consequence, large anthropogenic CO 2 sources worldwide will eventually be required to implement CO 2 capture and storage technologies to control CO 2 emissions. In order to guide the establishment of policies for CO 2 removal, we reviewed the current status of CO 2 capture patents and technologies based on the Espacenet patent database and found that more than 1000 patents have been published on sorbent, solvent, and membrane. More than 60% of these patents were published since the year 2000, and a sharp increase in patent numbers was seen in the last several years; ∼25% patents were published in the last 2 years. Substantially more patents on CO 2 removal and separation technologies are expected in the coming years. Meanwhile, the top four major types of patents, which consist of more than 2/3 of these patents, were patents granted by Japan (JP), United States (US), World Intellectual Property Organization (WO), and China (CN), and approximately half of the patents were JP and US patents. Unfortunately, no current technologies for removing CO 2 from large sources like coal-based power plants exist which satisfy the needs of safety, efficiency, and economy; further enhancement and innovation are much needed.

  20. Patenting and the gender gap: should women be encouraged to patent more?

    Science.gov (United States)

    de Melo-Martín, Inmaculada

    2013-06-01

    The commercialization of academic science has come to be understood as economically desirable for institutions, individual researchers, and the public. Not surprisingly, commercial activity, particularly that which results from patenting, appears to be producing changes in the standards used to evaluate scientists' performance and contributions. In this context, concerns about a gender gap in patenting activity have arisen and some have argued for the need to encourage women to seek more patents. They believe that because academic advancement is mainly dependent on productivity (Stuart and Ding in American Journal of Sociology 112:97-144, 2006; Azoulay et al. in Journal of Economic Behavior & Organization 63:599-623, 2007), differences in research output have the power to negatively impact women's careers. Moreover, in the case of patenting activity, they claim that the gender gap also has the potential to negatively affect society. This is so because scientific and technological advancement and innovation play a crucial role in contemporary societies. Thus, women's more limited involvement in the commercialization of science and technology can also be detrimental to innovation itself. Nevertheless, calls to encourage women to patent on grounds that such activity is likely to play a significant role in the betterment of both women's careers and society seem to be based on two problematic assumptions: (1) that the methods to determine women's productivity in patenting activities are an appropriate way to measure their research efforts and the impact of their work, and (2) that patenting, particularly in academia, benefits society. The purpose of this paper is to call into question these two assumptions.

    Biomedical text mining of scientific knowledge bases, such as Medline, has received much attention in recent years. Given that text mining is able to automatically extract biomedical facts that revolve around entities such as genes, proteins, and drugs, from unstructured text sources, it is seen as a major enabler to foster biomedical research and drug discovery. In contrast to the biomedical literature, research into the mining of biomedical patents has not reached the same level of maturity. Here, we review existing work and highlight the associated technical challenges that emerge from automatically extracting facts from patents. We conclude by outlining potential future directions in this domain that could help drive biomedical research and drug discovery. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The patenting activities of the former centrally planned economies in the US between 1976 and 1999 are examined. The technological performance of Eastern Europe is assessed and compared with that of the OECD countries. A sharp decline is observed as a consequence of the economic changes undergone by these countries in recent years. The study reveals some common technological strengths, such as in the areas of petroleum, coal, chemicals and other related products, and country-specific advantages, such as in mining in the former USSR, Poland and Bulgaria, textiles, clothing, footwear and leather in the former Czechoslovakia, printing, publishing and recorded media in the former East Germany, health in the former Yugoslavia, energy in Romania and design in Slovenia. Recommendations are made for the future use of foreign patents.

    The analysis of patent activity is one methodology used for technological monitoring. In this paper, the activity of biotechnology-related patents in Brazil were analyzed through 30 International Patent Classification (IPC) codes published by the Organization for Economic Cooperation and Development (OECD). We developed a program to analyse the dynamics of the major patent applicants, countries and IPC codes extracted from the Brazilian Patent Office (INPI) database. We also identified Brazilian patent applicants who tried to expand protection abroad via the Patent Cooperation Treaty (PCT). We had access to all patents published online at the INPI from 1975 to July 2010, including 9,791 biotechnology patent applications in Brazil, and 163 PCTs published online at World Intellectual Property Organization (WIPO) from 1997 to December 2010. To our knowledge, there are no other online reports of biotechnology patents previous to the years analyzed here. Most of the biotechnology patents filed in the INPI (10.9%) concerned measuring or testing processes involving nucleic acids. The second and third places belonged to patents involving agro-technologies (recombinant DNA technology for plant cells and new flowering plants, i.e. angiosperms, or processes for obtaining them, and reproduction of flowering plants by tissue culture techniques). The majority of patents (87.2%) were filed by nonresidents, with USA being responsible for 51.7% of all biotechnology patents deposited in Brazil. Analyzing the resident applicants per region, we found a hub in the southeast region of Brazil. Among the resident applicants for biotechnology patents filed in the INPI, 43.5% were from São Paulo, 18.3% were from Rio de Janeiro, and 9.7% were from Minas Gerais. Pfizer, Novartis, and Sanofi were the largest applicants in Brazil, with 339, 288, and 245 biotechnology patents filed, respectively. For residents, the largest applicant was the governmental institution FIOCRUZ (Oswaldo Cruz

  13. Why Is Hard To Patent An Invention?

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available When employed by a company, in almost all the cases a new employee has to sign an agreement giving the company exclusive rights to any intellectual property developed as part of their work assignments. This agreement could extend beyond a change of jobs and cause conflict of interests in new employment situations. A patent is a government-granted monopoly given to an inventor as both a reward for the intellectual and financial investment, and a stimulus to innovate. As a monopoly, the patent has legal power to exclude others from exploiting the invention in any way for a period of 20 years from the time the patent application has been filed. A trademark provides instant recognition of a product or company; a service mark provides instant recognition of a service. They both have unlimited lifetime. But the owner must renew or confirm continuous use at the end of five years, and every 10 years thereafter. A trade secret is information keep secret by the owner to give him advantage over competitors. Since it is secret, a trade secret protection has unlimited lifetime.

    Recently, the situation of Chinese patent application is pleasant, but there are still some hiding disquiets. For the most enterprises, the passion of current patent application may not be derived from the internal motility but mainly derived by the government policy. Because of the shortage of related knowledge on patent, there are still some problems for our enterprises, such as blurring the scope of patent application and failing the organization of the documents of patent application which causing the patent cannot be applied timely. In some cases, the patent cannot obtain the effective protection even if it has been applied and obtained the authorization successfully. For such problems, we should enhance the cooperation between enterprises and agency organizations and build a patent engineer group which should participate in the whole R and D process and can prepare the documents of the patent application effectively and timely. What's more, we should inhibit the phenomena of infringement of patent rights and use 'existing technique' effectively by the methods of document retrieval. (authors)

    Full Text Available Australia, like most countries, faces high and rapidly-rising drug costs. There are longstanding concerns about pharmaceutical companies inappropriately extending their monopoly position by "evergreening" blockbuster drugs, through misuse of the patent system. There is, however, very little empirical information about this behaviour. We fill the gap by analysing all of the patents associated with 15 of the costliest drugs in Australia over the last 20 years. Specifically, we search the patent register to identify all the granted patents that cover the active pharmaceutical ingredient of the high-cost drugs. Then, we classify the patents by type, and identify their owners. We find a mean of 49 patents associated with each drug. Three-quarters of these patents are owned by companies other than the drug's originator. Surprisingly, the majority of all patents are owned by companies that do not have a record of developing top-selling drugs. Our findings show that a multitude of players seek monopoly control over innovations to blockbuster drugs. Consequently, attempts to control drug costs by mitigating misuse of the patent system are likely to miss the mark if they focus only on the patenting activities of originators.

    Background and Purpose: A patent foramen ovale has been reported to be significantly more frequent in young stroke patients than in matched control subjects, and paradoxical embolism has been suggested as the main mechanism of stroke in-this situation. The present study was designed to test this hypothesis. Methods: Sixty-eight consecutive patients under 55 years of age presenting with an ischemic stroke had an extensive workup, including transesophageal echocardiography with contrast. We compared the prevalence of criteria for the diagnosis of paradoxical embolism in patients with and without a patent foramen ovale. Results: A patent foramen ovale was found in 32 patients (47%). A Valsalva-provoking activity was present at stroke onset in six patients with a patent foramen ovale and in eight patients with no patent foramen ovale (X(sup 2)=0.1, nonsignificant). Clinical/radiological features suggestive of an embolic mechanism were not more frequent in patients with a patent foramen ovale. Clinical evidence of deep vein thrombosis was present in one patient with a patent foramen ovale and in none of the others. No occult venous thrombosis was found in a subgroup of patients with a patent foramen ovale and no definite cause for stroke who underwent venography (n=13). Conclusions. Our results do not support the hypothesis that paradoxical embolism is the primary mechanism of stroke in patients with a patent foramen ovale.

    2015-01-01

    Pharmaceutical patenting involves writing claims based on both discoveries already made, and on prophesy of future developments in an ongoing project. This is necessitated by the very different timelines involved in the drug discovery and product development process on the one hand, and successful patenting on the other. If patents are sought too early there is a risk that patent examiners will disallow claims because of lack of enablement. If patenting is delayed, claims are at risk of being denied on the basis of existence of prior art, because the body of relevant known science will have developed significantly while the project was being pursued. This review examines the role of prophetic patenting in relation to the essential predictability of many aspects of drug discovery science, promoting the concepts of discipline-related and project-related prediction. This is especially directed towards patenting activities supporting commercialization of academia-based discoveries, where long project timelines occur, and where experience, and resources to pay for patenting, are limited. The need for improved collaborative understanding among project scientists, technology transfer professionals in, for example, universities, patent attorneys, and patent examiners is emphasized.

    Full Text Available In order that the invention solving a technical problem receives a patent protection, it is necessary to file a patent application. For the protection of confidential inventions which are important for defense and national security, a confidential patent application[1] must be filed. A confidential patent application is an important and complex document, the parts of which are,  in principle, exposed in an established order. For the preparation of patent applications, it is necessary to engage experts with higher education, primarily in the technical field the invention relates to. The contents of the patent application is a basis for examining whether the application meets the requirements for patentability and whether the right to patent protection is achieved. Besides theoretical discussions on patent application, the paper gives a short version of an example of an application regarding a protected confidential invention. Introduction The basic condition for the exercise of patent protection is filing a patent application, the test procedure and, eventually, depending on the test results - the recognition or rejection of the patent. The paper gives a description of all parts of the patent application on an example of a confidential invention already patented. The content of the confidential patent application The confidential patent application for confidential invention protection consists of the following parts: The application for a patent; description of the invention; the claims (indication of what is new and what is required to be protected by patenting; abstract (short summary of the invention  and a draft of the invention (to which the description and the claims are referred.

    2010-12-01

    Full Text Available As diseases continue to spread around the globe, pharmaceutical and biotech companies continue to search for new and better drugs to treat them. Most of these companies have realised that useful compounds for these purposes may be found in the natural resources that indigenous and local communities use. And yet, even though the importance of these biological resources to global health and economic livelihood is well recognised, the legal ownership and control of this traditional knowledge is still very controversial. This article undertakes a comparative analysis of American and European, as well as international legal regulations on patent law and traditional knowledge. Key questions include: What is traditional knowledge? How have the national patent laws of these countries treated the protection of plant variety and plant genetic resources? What are the existing international standards for patents, and what implications do they have for protecting traditional knowledge? And finally, what protection systems are emerging for the future?

    Glivec (imatinib mesylate), produced by the pharmaceutical company Novartis, is prescribed in the case of chronic myeloid leukemia, one of the most common blood cancers in eastern countries. After more than a decade of legal battles surrounding its patentability, the Supreme Court of India gave its final decision on April 1st of 2013, rejecting the appeal of the Swiss giant drug manufacturer. In 2006, the Indian Patent Office first refused Glivec's patent under Section 3(d) of the Indian Patent Act arguing that it was only a modified version of an existing drug, Imatinib, and therefore that the drug was not innovative. Novartis replied filing legal challenges against the Indian government but the final verdict in April of 2013 ends the battle. Indeed, the Supreme Court stated that even if the bioavailability of the drug was improved, it did not demonstrate enhanced efficacy and that Glivec was not patentable. The research primarily focused on journal, newspaper and magazine articles relevant to the time frame of the lawsuit (from 1994 to 2013) as well as news searches through Google, Factiva, ProQuest, PubMed, and YouTube where press articles from court verdicts were obtained by using the following keywords: "India", "Novartis", "Glivec", "Patent", "Novartis Case", and "Supreme Court of India". The data sources were interpreted and analyzed according to the authors' own prior knowledge and understanding of the exigencies of the TRIPS Agreement. This case illuminates how India is interpreting international law to fit domestic public health needs. The Novartis case arguably sets an important precedent for the global pharmaceutical industry and ideally will help improve access to lifesaving medicines in the developing world by demanding that patient health needs supersede commercial interests. The Supreme Court of India's decision may affect the interpretation of the article of the TRIPS Agreement, which states members shall be free to determine the appropriate method

  3. Commentary on patents: Don`t dismiss Rifkin`s damning of gene patents

    Energy Technology Data Exchange (ETDEWEB)

    Hoyle, R.

    1995-07-01

    Biotech may have less to fear from Rifkin than from its own inclination to dismiss the fact that the evolution of ethics and patent laws applying to patenting genes has been haphazard. Perhaps it is time for the biotechnology industry to get behind the establishment of an effective forum for opening much-needed dialogue. Perhaps a Senate proposal to establish a bioethics commission, which reportedly has bogged down in partisan politics, is just such a venue for the government and private sector to begin to hash out the ethical and legal dilemmas that are indisputably at the heart of the biotechnology industry, and its future success.

    INDENA SPA Company in Italy is a multi-national company that produces and sells plant extracts. Based on its own re- search advantages in the field of Ginkgo biloba preparation, the company protects its own products market effectively through building patent portfolio around the patents of its opponent. Based on the multi-angle analysis for patent portfolio of G. biloba preparation from the aspects of application time, legal status, technical development route, and patent portfolio layout, this article provides technical reference on research and development of G. biloba preparation, and the author suggest that Chinese applicants learn techniques and layout experiences of other patents fully to enhance the level of research and patent protection level.

    2014-09-01

    Japan has made 'innovation in science and technology' as one of its central pillars to ensure high growth in its next stage of economic development and its life sciences market which hosts regenerative medicine was proclaimed to be 'the best market in the world right now.' Although life science therapeutic inventions are patentable subject matter under Japanese patent law, there are nuanced obviousness and enablement challenges under Japanese patent law that can be surmounted in view of some encouraging Japanese court developments in fostering a pro-patent applicant environment in the life sciences therapeutic patent field. Nevertheless, great care must be taken when drafting and prosecuting such patent applications in the world's second most important life sciences therapeutic market.

  6. What is the Destiny of Patents of Brazilian Universities?

    Directory of Open Access Journals (Sweden)

    André Luiz de Souza Querido

    2011-03-01

    Full Text Available The power of patent is expressed when the innovative product or process goes to market, and the exclusive right that patent ensures generates the market power, and the holder possibility to obtain competitive advantage over competitors. Thus, it becomes compelling the discussions on the universities need for transformation of patent applications efforts into granted patents, which could be negotiated with a higher degree of juridical certainty and, consequently, higher value added. To establish an Index of Patents Granting, and understand the importance of Technological Innovation Nuclei for the increase of this index, it was developed a survey on the number of patents granted to Brazilian universities and evaluated the structure of Technological Innovation Nuclei of these universities. From the survey on the granting cases, it was verified that the universities presenting, among other characteristics, better structured Technological Innovation Nuclei stood out.

  7. How are pharmaceutical patent term extensions justified? Australia's evolving scheme.

    Science.gov (United States)

    Lawson, Charles

    2013-12-01

    This article examines the evolving patent term extension schemes under the Patents Act 1903 (Cth), the Patents Act 1952 (Cth) and the Patents Act 1990 (Cth). The analysis traces the change from "inadequate remuneration" to a scheme directed specifically at certain pharmaceuticals. An examination of the policy justification shows there are legitimate questions about the desirability of any extension. The article concludes that key information provisions in the Patents Act 1990 (Cth) that might assist a better policy analysis are presently not working and that any justification needs evidence demonstrating that the benefits of patent term extensions to the community as a whole outweigh the costs and that the objectives of extensions can only be achieved by restricting competition.

  8. Nanotechnology strength indicators: international rankings based on US patents

    Science.gov (United States)

    Marinova, Dora; McAleer, Michael

    2003-01-01

    Technological strength indicators (TSIs) based on patent statistics for 1975-2000 are used to analyse patenting of nanotechnology in the USA, and to compile international rankings for the top 12 foreign patenting countries (namely Australia, Canada, France, Germany, Great Britain, Italy, Japan, Korea, the Netherlands, Sweden, Switzerland and Taiwan). As the indicators are not directly observable, various proxy variables are used, namely the technological specialization index for national priorities, patent shares for international presence, citation rate for the contribution of patents to knowledge development and rate of assigned patents for potential commercial benefits. The best performing country is France, followed by Japan and Canada. It is shown that expertise and strength in nanotechnology are not evenly distributed among the technologically advanced countries, with the TSIs revealing different emphases in the development of nanotechnology.

  9. Patent holdings of US biotherapeutic companies in major markets.

    Science.gov (United States)

    Sebastian, Teena E; Yerram, Chandra Bindu; Saberwal, Gayatri

    2009-05-01

    In previous studies we examined the (United States, US) patent holdings of 109 largely North American biotech companies developing therapeutics that, in particular, have an interest in discovery stage science. There appears little correlation between the number of patents and the number of products of individual companies. Here we quantified and compared the 103 US-headquartered companies' patent holdings in Australia, Canada, Europe, Japan and the US. The companies demonstrate variable and surprising patterns of patent holdings across these countries or regions. For most companies, patent holdings are not in proportion to the importance of the country as a biotech or pharma market. These results have implications for the patenting strategies of small biotech companies involved in drug discovery.

  10. The Battle for Patent Rights in Plant Biotechnology

    Schneider, Cédric

    2011-01-01

    This paper describes and analyzes the occurrence and extent of oppositions initiated against plant biotechnology patents granted by the European Patent Office (EPO). The opposition mechanism is a legal procedure that allows any third party to challenge the validity of patents awarded by the EPO....... Results indicate that the opposition rate is far greater in plant biotechnology than in other emerging industries. Consistent with theoretical predictions, the empirical findings suggest that opposed patents are disproportionately those that score high on features that proxy for their “value” or “quality......”. In contrast to previous findings, however, the results show that large-volume applicants are more likely to be opposed. Because the boundaries of plant biotech patents are ill-defined, large patent portfolios do not promote cooperative behavior such as licensing or settlements. The analysis rejects...

  17. Patent foramen ovale and migraine attacks: a systematic review.

    Lip, Philomena Z Y; Lip, Gregory Y H

    2014-05-01

    Migraine headache and the presence of a patent foramen ovale have been associated with each other, although the precise pathophysiological mechanism(s) are uncertain. The purpose of this systematic review was to identify the extent of patent foramen ovale prevalence in migraineurs and to determine whether closure of a patent foramen ovale would improve migraine headache. An electronic literature search was performed to select studies between January 1980 and February 2013 that were relevant to the prevalence of patent foramen ovale and migraine, and the effects of intervention(s) on migraine attacks. Of the initial 368 articles presented by the initial search, 20 satisfied the inclusion criteria assessing patent foramen ovale prevalence in migraineurs and 21 presented data on patent foramen ovale closure. In case series and cohort studies, patent foramen ovale prevalence in migraineurs ranged from 14.6% to 66.5%. Case-control studies reported a prevalence ranging from 16.0% to 25.7% in controls, compared with 26.8% to 96.0% for migraine with aura. The extent of improvement or resolution of migraine headache attack symptoms was variable. In case series, intervention ameliorated migraine headache attack in 13.6% to 92.3% of cases. One single randomized trial did not show any benefit from patent foramen ovale closure. The data overall do not exclude the possibility of a placebo effect for resolving migraine following patent foramen ovale closure. This systematic review demonstrates firstly that migraine headache attack is associated with a higher prevalence of patent foramen ovale than among the general population. Observational data suggest that some improvement of migraine would be observed if the patent foramen ovale were to be closed. A proper assessment of any interventions for patent foramen ovale closure would require further large randomized trials to be conducted given uncertainties from existing trial data.

  19. Do patents impede the provision of genetic tests in Australia?

    Science.gov (United States)

    Nicol, Dianne; Liddicoat, John

    2013-06-01

    Health policy and law reform agencies lack a sound evidence base of the impacts of patents on innovation and access to healthcare to assist them in their deliberations. This paper reports the results of a survey of managers of Australian genetic testing laboratories that asked a series of questions relating to the tests they perform, whether they pay to access patented inventions and whether they have received notifications from patent holders about patents associated with particular tests. Some diagnostics facilities are exposed to patent costs, but they are all located in the private sector. No public hospitals reported paying licence fees or royalties beyond those included in the price of commercial test kits. Some respondents reported having received enforcement notices from patent holders, but almost all related to the widely known breast cancer-associated patents. Respondents were also asked for their views on the most effective mechanisms to protect their ability to provide genetic tests now and in the future. Going to the media, paying licence fees, ignoring patent rights and relying on the government to take action were widely seen as most effective. Litigation and applications for compulsory licences were seen as some of the least effective mechanisms. These results provide an evidence base for development of health policy and law reform. What is known about the topic? The impact of patents on the delivery of genetic testing services remains unclear in Australia. What does this paper add? The survey reported in this paper suggests that, aside from well-known enforcement actions relating to the breast cancer associated patents, there is little evidence that providers of genetic testing services are being exposed to aggressive patent-enforcement practices. What are the implications for practitioners? Although patent-enforcement actions may increase in the future, a range of strategies are available to providers of testing services to protect them against

    2007-10-01

    Full Text Available Patents in general contain much novel technological information. This paper demonstrates that the usage of patent analysis can facilitate a unique scheme for tracking technology development. In this paper, the walking technique of the Japanese biped robot is tracked as an example. The searching method of the FI (file index and F-term classification system developed by JPO (Japan Patent Office was employed in this study, where all the related patent data were searched from the IPDL (Intellectual Property Digital Library. This study investigated an important technique applied to the humanoid biped robot that imitates the walking behavior of the human beings on two legs. By analyzing the patent information obtained, the relative research capabilities, technical strengths, and patent citation conditions among patent competitors were compared. Furthermore, a formulated technical matrix of patent map is established in this paper to indicate that the ZMP (Zero Moment Point control means is the main technology to achieve stabilized walking control of the humanoid biped robot. This study also incorporates relevant academic journal findings and industrial information. Results presented herein demonstrate that patents can function not only as a map for tracking a technology trajectory, but also as a guide to the main development of a new technology in years to come.

Some of the major points...... of discussion have been focused on the scope of protection (e.g. purpose-bound protection) and gene patents being subject to a specific DNA regime on patent rights. The Directive can be interpreted as favouring such a solution, but so far the European Commission has decided neither to support nor reject...

    Patent ductus arteriosus is a common congenital cardiac defect comprising 5-10% of all these defects in term neonates. Although open chest and video-assisted interruption are still in use, transcatheter occlusion has rapidly become the first choice for patent ductus arteriosus closure in the appropriate patient. Percutaneous closure of patent ductus arteriosus is widely done by transvenous approach guided by aortic access. We present the case of a 2 year old girl who underwent patent ductus arteriosus device occlusion with transvenous access only.

    We enrich the treatment of the absorptive capacity phases including the moderating effects between routines associated to the traditional potential-realized absorptive capacities. Taking into account external knowledge search strategies, the deeper external relationships, the better transference and appropriation of specific external knowledge. Nevertheless, when the moderating role of assimilation is included, cooperation agreements appear as the most efficient source of external knowledge. Finally, we show that technological tools let firms store and structure the information making easier its use for international patenting. This positive effect is reinforced in the presence of exploitation routines, since technological knowledge will better fit to the industry's key factors of success.

  11. Patents for critical pharmaceuticals: the AZT case.

    Science.gov (United States)

    Ackiron, E

    1991-01-01

    Patents and other statutory types of market protections are used in the United States to promote scientific research and innovation. This incentive is especially important in research intensive fields such as the pharmaceutical industry. Unfortunately, these same protections often result in higher monopoly pricing once a successful product is brought to market. Usually this consequence is viewed as the necessary evil of an incentive system that encourages costly research and development by promising large rewards to the successful inventor. However, in the case of the AIDS drug Zidovudine (AZT), the high prices charged by the pharmaceutical company owning the drug have led to public outcry and a re-examination of government incentive systems. This Note traces the evolution of these incentive programs--the patent system, and, to a lesser extent, the orphan drug program--and details the conflicting interests involved in their development. It then demonstrates how the AZT problem brings the interest of providing inventors with incentives for risky innovative efforts into a sharp collision with the ultimate goal of such systems: ensuring that the public has access to the resulting products at a reasonable price. Finally, the Note describes how Congress and the courts have attempted to resolve these problems in the past, and how they might best try to solve the AZT problem in the near future.

    Albert Einstein may be best known as the wire-haired whacky physicist who gave us the theory of relativity, but that's just one facet of this genius' contribution to human knowledge and modern science. As Jozsef Illy expertly shows in this book, Einstein had an eminently practical side as well. As a youth, Einstein was an inveterate tinkerer in the electrical supply factory his father and uncle owned and operated. His first paid job was as a patent examiner. Later in life, Einstein contributed to many inventions, including refrigerators, microphones, and instruments for aviation. In published papers, Einstein often provided ways to test his theories and fundamental problems of the scientific community of his times. He delved deeply into a variety of technological innovations, most notably the gyrocompass, and consulted for industry in patent cases and on other legal matters. Einstein also provided explanations for common and mundane phenomena, such as the meandering of rivers. In these and other hands-on exam...

  15. Expedited patent examination for green inventions: Developing countries' policy choices

    International Nuclear Information System (INIS)

    Lu, Bingbin

    2013-01-01

    Innovation in green technology is important. Patent rights can provide incentives for green technology research and development. Expedited patent examination for green inventions has emerged as a policy instrument to provide such incentives. Developing countries were never opposed to patents for green technologies. China and Brazil have led the way by offering expedited examinations for green patent applications. More developing countries are expected to follow. Expedited examination for green technologies is consistent with the intellectual property system objectives and is justified by the clear social benefit from green technologies. Introducing such expedited programs in developing countries has sufficient advantages. Existing models of expedited programs for green technologies are analyzed to generalize key issues and to discern suitable policy choices for developing countries. When introducing such programs, a balanced definition for green technology is preferred; a special classification requirement is premature and is not recommended; a pre-examination search requirement is generally recommended to balance patent office workloads, and a green patent database is recommended. - Highlights: • There is no north–south divide in promoting green technologies. • Earlier issuance of green patents has its great social benefit. • Green patent application should receive expedited examination. • Developing countries should introduce such expedited programs. • A suitable approach for developing countries is searched and recommended

    The most common congenital heart disease in the newborn population, patent ductus arteriosus, accounts for significant morbidity in preterm newborns. In addition to prematurity and environmental factors, we hypothesized that genetic factors play a significant role in this condition. The objective of this study was to quantify the contribution of genetic factors to the variance in liability for patent ductus arteriosus in premature newborns. A retrospective study (1991-2006) from 2 centers was performed by using zygosity data from premature twins born at Patent ductus arteriosus was diagnosed by echocardiography at each center. Mixed-effects logistic regression was used to assess the effect of specific covariates. Latent variable probit modeling was then performed to estimate the heritability of patent ductus arteriosus, and mixed-effects probit modeling was used to quantify the genetic component. We obtained data from 333 dizygotic twin pairs and 99 monozygotic twin pairs from 2 centers (Yale University and University of Connecticut). Data on chorioamnionitis, antenatal steroids, gestational age, body weight, gender, respiratory distress syndrome, patent ductus arteriosus, necrotizing enterocolitis, oxygen supplementation, and bronchopulmonary dysplasia were comparable between monozygotic and dizygotic twins. We found that gestational age, respiratory distress syndrome, and institution were significant covariates for patent ductus arteriosus. After controlling for specific covariates, genetic factors or the shared environment accounted for 76.1% of the variance in liability for patent ductus arteriosus. Preterm patent ductus arteriosus is highly familial (contributed to by genetic and environmental factors), with the effect being mainly environmental, after controlling for known confounders.

    2017-07-01

    Construction biotechnology includes research and development of construction materials and processes that make use of various microbes. The present technology landscape gives a perspective on how microbes have been used in construction industry as cement and concrete additives by analyzing patents filed in this technology arena. All patents related to the technology of interest published globally to date have been reviewed. The earliest patent filing in this technology domain was recorded in the year 1958 and the patenting activity reached its peak around mid to late 1990s. The early technology was mainly focused on microbial polysaccharides and other metabolic products as additives. Year 2002 onwards, biomineralization has taken precedence over the other technologies with consistent patent filings indicating a shift in innovation focus. Japan has been the global leader with highest number of patents filed on application of microbes in construction industry. Southeast University, China has topped the patent assignee list with maximum number of filings followed by Kajima Corp. and Shin-Etsu Chemical Co., Ltd. Most patent applications have claimed microbe based bio-products. Construction-related microbial technologies are mainly based on activity of different microorganisms such as urease-producing, acidogenic, halophilic, alkaliphilic, nitrate and iron-reducing bacteria. Sporosarcina pasteurii has been the most widely used microbe for biomineralization.

As a result, firms risk to be blocked in their patent applications or to be infringed upon by rivals. While...... both aspects constitute major challenges for the appropriation of returns to inventive activity, extant literature suggests that participation in the market for technology might actually resolve or at least alleviate these problems. In this paper, we investigate the effect of patent blocking...... and infringement on firms’ engagement in in- and cross-licensing. Based on a sample of more than 1000 German manufacturing firms our results show that firms engage in in-licensing as a reaction to patent blocking and in both in- and cross-licensing if their protected IP was infringed upon. However, these effects...

    Pharmaceutical success in the market is the best reward for pharmaceutical investors undergoing the lengthy, costly and risky process of pharmaceutical Research and Development (R&D). Drugs with high market revenues trigger fierce competition between pharmaceutical enterprises, as is demonstrated by the increasing Mergers & Acquisitions (M&A) cases focusing on seizing the best-selling products. On the other hand, patents, as the best shield for innovative drugs against generic drugs, become a powerful weapon for pharmaceutical enterprises to win the substantial returns generated by market exclusivity. Patents seem to be directly responsible for the commercial success of new medicines. In this context, it is of great significance to find out the empirical associations between pharmaceutical commercial success and patents. By comprehensively analysing 127 drugs marketed in the USA and their 621 American patents, this article identifies the evidence to link various patent indicators with pharmaceutical sales in actual market.

    Stem cell research and the intellectual property derived from it, because of its potential to completely transform health care, demand an especially high level of consideration from business and patent prosecution perspectives. As with other revolutionary technologies, ordinary risks are amplified (e.g., litigation), and ordinarily irrelevant considerations may become important (e.g., heightened level of both domestic and foreign legislative risk). In the first part of this article, general strategies for patent prosecutors such as several prosecution considerations and methods for accelerating patent prosecution process are presented. In the second part, patent prosecution challenges of stem cell-related patents and possible solutions are discussed. In the final part, ethical and public policy issues particular to stem cell-related and other biotechnological inventions are summarized.

    The study was concerned with countermeasures against a possible smallpox outbreak. In the process of assessment 18 landscaping sectors were defined and described, the advantages and drawbacks of the corresponding countermeasures being reviewed. The data of the previously published influenza landscape were revisited. The current economic climate of deficit cutting (austerity) also puts emphasis on the optimization of capital investment. We used the materials of the landscape to define and analyze metrics of capital placement optimization. Value score was obtained by fitting patent landscape internals to the sale price of individual patents. Success score was obtained as a product of a-priori parameters that measure likelihood of emergence of a marketable product in a technological sector. Both scores were combined in a qualitative metric. Our methodology defined weight as a product of the sector size by the success score. We hypothesized - based on the material of two landscapes- that a life cycle of a technology begins in IP space with a high patent quality low volume "bud" of low weight, reaches maximum weight and then weight falls again when the technology becomes outdated. The weight and the annual dynamic of weight can serve a measure of investment risk and return. In this report we modeled investment by issue of government grants or purchase of patents by government. In the smallpox landscape the number of patents purchased by government agencies was the highest in the sectors with the highest weight and the trend was confirmed by the count of NIH grants issued in support of the technological sectors. In the influenza landscape only grant issue count was statistically meaningful and the trend was also confirmed. To better fit the grant support levels, the weight expression was optimized by using training coefficients. We propose to use value scores for evaluation of individual patent publications/company portfolios and to use weights for assessment of

    Full Text Available Dyspnea accounts for more than one-fourth of the hospital admissions from Emergency Department. Chronic conditions such as Chronic Obstructive Pulmonary Disease, Congestive Heart Failure, and Asthma are being common etiologies. Less common etiologies include conditions such as valvular heart disease, pulmonary embolism, and right-to-left shunt (RLS from patent foramen ovale (PFO. PFO is present in estimated 20–30% of the population, mostly a benign condition. RLS via PFO usually occurs when right atrium pressure exceeds left atrium pressure. RLS can also occur in absence of higher right atrium pressure. We report one such case that highlights the importance of high clinical suspicion, thorough evaluation, and percutaneous closure of the PFO leading to significant improvement in the symptoms.

    Actinic keratosis is a common premalignant skin lesion. Because of its increasing incidence, several efforts have been made to earlier detectection and to improve knowledge on photocarcinogenic pathways of keratinocytes. As a consequence, recently new discoveries have been done in this field. Starting from our previous review on actinic keratosis, we reviewed the literature focusing on pathogenesis and new patents in order to highlight the most recent progresses in diagnosis and therapeutic approach. Although several efforts have been done in the field of photodamaged skin, new upgrades in diagnosis and therapy are needed to detect superficial actinic keratosis earlier, to improve the disease free survival of patient and to better treat the field cancerization.

    Patents are an essential information source used to monitor, track, and analyze nanotechnology. When it comes to search nanotechnology-related patents, a keyword search is often incomplete and struggles to cover such an interdisciplinary discipline. Patent classification schemes can reveal far better results since they are assigned by experts who classify the patent documents according to their technology. In this paper, we present the most important classifications to search nanotechnology patents and analyze how nanotechnology is covered in the main patent classification systems used in search systems nowadays: the International Patent Classification (IPC), the United States Patent Classification (USPC), and the Cooperative Patent Classification (CPC). We conclude that nanotechnology has a significantly better patent coverage in the CPC since considerable more nanotechnology documents were retrieved than by using other classifications, and thus, recommend its use for all professionals involved in nanotechnology patent searches.

    Document search on PubMed, the pre-eminent database for biomedical literature, relies on the annotation of its documents with relevant terms from the Medical Subject Headings ontology (MeSH) for improving recall through query expansion. Patent documents are another important information source, though they are considerably less accessible. One option to expand patent search beyond pure keywords is the inclusion of classification information: Since every patent is assigned at least one class code, it should be possible for these assignments to be automatically used in a similar way as the MeSH annotations in PubMed. In order to develop a system for this task, it is necessary to have a good understanding of the properties of both classification systems. This report describes our comparative analysis of MeSH and the main patent classification system, the International Patent Classification (IPC). We investigate the hierarchical structures as well as the properties of the terms/classes respectively, and we compare the assignment of IPC codes to patents with the annotation of PubMed documents with MeSH terms.Our analysis shows a strong structural similarity of the hierarchies, but significant differences of terms and annotations. The low number of IPC class assignments and the lack of occurrences of class labels in patent texts imply that current patent search is severely limited. To overcome these limits, we evaluate a method for the automated assignment of additional classes to patent documents, and we propose a system for guided patent search based on the use of class co-occurrence information and external resources.

    The application of biotechnology is a potential tool for mitigating the present and future fooding and clothing demands in developing countries like India. The commercialization of biotechnological products might benefiting the poor`s in developing countries are unlikely to be developed. Biotechnology has the potential to provide a wide range of products and the existing production skills in the industrial, pharmaceuticals and the agricultural sector. Ownership of the intellectual property rights is the key factors in determining the success of any technological invention, which was introduced in the market. It provides the means for technological progress to continue of the industry of the country. The new plans, animal varieties, new methods of treatments, new crops producing food articles as such are the inventions of biotechnology. Biotechnology is the result of the application of human intelligence and knowledge to the biological processes. Most of the tools of biotechnology have been developed, by companies, governments, research in- stitutes and universities in developed nations. These human intellectual efforts deserve protection. India is a developing country with advance biotechnology based segments of pharmaceutical and agricultural industries. The Trade Related Intellectual Property Rights (TRIPS) is not likely to have a significant impact on incentives for innovation creation in the biotechnology sectors. In the recent years, the world has seen the biotechnology sector as one of greatest investment area through the Patent Law and will giving huge profit in future. The Research and Development in the field of biotechnology should be encouraged for explor- ing new tools and improve the biological systems for interest of the common people. Priority should be given to generation, evaluation, protection and effective commercial utilization of tangible products of intellectual property in agriculture and pharmaceuticals. To support the future growth and

    2014-12-01

    Full Text Available As notícias sobre as guerras internacionais desencadeadas no marco da Guerra Fria têm sido utilizadas pela discursividade nacionalista em pós do seu programa político próprio, mais vinculado ao contexto local do que ao internacional.O semanário político dos anos cinqüenta e sessenta, Azul y Blanco, virou testemunha disso. Este, embora tenha-se concentrado principalmente na política nacional, deixou filtrar em suas páginas notícias internacionais que expunham as problemáticas mais importantes da Guerra Fria nesses anos, desde uma óptica nacionalista que ia mais longe das identidades nacionais para construir um “nós” geograficamente mais amplo. Assim, apesar da maior relevância da Revolução Cubana nas páginas da revista, a situação do bloco oriental europeu e a Guerra do Vietnã foram também importantes na secção internacional. Essas notícias eram escritas por correspondentes e editores argentinos e estrangeiros. Ambos argentinos e estrangeiros tiveram posicionamentos políticos e ideológicos que ficaram comprometidos com seus respectivos cenários locais. Assim, eles contribuíram especialmente para as transformações que atravessava o discurso nacionalista local. Nesse sentido, as redefinições ideológicas e políticas do nacionalismo argentino desses anhos nutriram-se também de aqueles olhares.

    The Azul mining complex, located in the Carajás Mineral Province, Amazon region, encompasses the most important manganese mine in Brazil. Vale S.A. company operates three simultaneous open pit excavations (mines 1, 2, and 3) in the area, which are conducted on rock alteration products of low geomechanical quality related to sandstones, siltstones, and a lateritic cover. In order to monitor ground deformation, 33 TerraSAR-X (TSX-1) StripMap images covering the period of March 2012-April 2013 were used in the investigation. An advanced differential interferometric synthetic aperture radar (A-DInSAR) approach based on persistent scatterer interferometry (PSI) using an interferometric point target analysis algorithm was applied, and the results showed that most of the area was considered stable during the time span of the synthetic aperture radar acquisitions. However, persistent scatterers (PS) with high deformation rates were mapped over a waste pile, probably related to settlements, and also along the north flank of mine 1, indicative of cut slope movements toward the center of the pit. A spatial relationship of geological structures with PS was observed for this sector of the mine, given by PS showing deformation rates concentrated along a structural corridor with faults, fractures, and folds related to the Carajás fault system. Though only ground-based radar measurements for wall benches of mine 1 were available for a short time period of the TSX-1 coverage, the PS movement patterns showed concordance with geotechnical field measurements. The investigation emphasized the important role that satellite-based A-DInSAR can play for deformation monitoring and risk assessment in this kind of mining area.

    An environmental diagnosis was conduced in the Relleno Sanitario Rio Azul to evaluate the state of the generation, the harvesting and the leached treatment system. Besides, the corrective measures for each case were determined. The physicochemical characterization of the leached generated has been established through the collection of historical analysis conduced and the implementation of an environmental monitoring plan. As a consequence of said characterization, it was concluded that the leached generated at present possesses the specific characteristics of backfills that are found in mature stage (methanogenic), to know: low relation DBO/DQO, slightly basic pH, low concentration of heavy metals and low biodegradability. Even so these liquids must be treated to fulfill the permissible maximum parameters that establish the Reglamento de Uso y Vertido de Aguas Residuales. A seasonal variation linked with the generation of leached was determined, by effects of infiltration, toward the mass of waste and the combination of pluvial water with leached, mainly due to the absence of adequate infrastructure and unfinished works. The amount of leached that was generated and that will be generated until year 2025 it was managed to consider by means of the modeling a hydric balance. The volume is significant and is due to adopt the respective sanitary measures to guarantee to long term the adapted treatment of the leached and the fulfillment of the effective legislation. A series of improvements are proposed to the leached treatment system that functions at present, as a consequence of the diagnosis carried out to achieve that the quality of the effluent treated comply with the parameters of poured established; such as: filtration of heavy particles, implementation of a physicochemical treatment and treatment of muds.

    Bioengineering has come of ages by setting up spare parts manufacturing units to be used in human body such as invasive implants and interventional controlled drug delivery in vivo systems. As a matter of fact patients on basis of their fiscal strength have the option to undergo prophylactic tactical manoeuvre for longer life spans. In this sphere of invasive implants, biocompatible polymer implants are a state of the art cutting edge technology with outstanding innovations leading to number of very successful start-up companies with a plethora of patent portfolios. From 2000 onwards, patent filings and grants for biocompatible polymers are expanding. Currently definition of biocompatibility is quite ambiguous with respect to the use of FDA approved polymeric materials. This article analysed patent portfolios for the trend patterns of prolific biocompatible polymers for capitalization and commercialization in the forthcoming years. Pair Bulk Data (PBD) portal was used to mine patent portfolios. In this patent preliminary analysis report, patents from 2000 to 2015 were evaluated using 317(c) filings, grants and classifications data for poly(vinyl alcohol) (PVA), poly(glycolic acid) (PGA), poly(hydroxyalkanoates) (PHAs) and poly(lactic acid) (PLA). This patent portfolio preliminary analysis embarks into patent analysis for New Product Development (NPD) for corporate R&D investment managerial decisions and on government advocacy for federal funding which is decisive for developmental advances. An in-depth patent portfolio investigation with return of investment (RoI) is in the pipeline. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: No período peri-operatório, o risco de anafilaxia deve sempre ser considerado. A incidência de reações alérgicas em anestesia é controversa, variando entre 1/3000 a 1/20.000, com mortalidade entre 3% e 9 %. Neste caso, relata-se o uso do azul de metileno como coadjuvante ao tratamento do choque anafilático refratário à terapêutica tradicional. RELATO DO CASO: Paciente do sexo masculino, 53 anos, submetido a herniorrafia inguinal sob raquianestesia. No final do procedimento, ao receber dipirona (1,5 g, por via venosa, o paciente imediatamente apresentou broncoespasmo, cianose, diminuição da SpO2 e da PAS, culminando com parada cardiorrespiratória. Foi iniciada reanimação cardiorrespiratória com massagem cardíaca externa, seguida de IOT e injeção de adrenalina (1 mg, atropina (1 mg, restabelecendo-se FC de 150 bpm, porém sem pulso palpável. Administrou-se mais 1 mg de adrenalina além de 1 g de hidrocortisona, com restabelecimento de pulso central (8 minutos. Apesar de receber dopamina (20 µg.kg-1.min-1, o paciente manteve-se hipotenso (60 mmHg até 80 minutos. Administraram-se 100 mg de azul de metileno por via venosa, quando houve aumento da PAS para 85 e 105 mmHg, após a segunda dose. Seguiu-se da diminuição da dose de dopamina de 20 para 10, 7, 5 e, finalmente, 2 µg.kg-1.min-1. CONCLUSÕES: A anafilaxia tem como principal mediador a liberação de histamina, que induz a produção de óxido nítrico (NO, com conseqüente aumento da guanilato ciclase que promove vasodilatação arteriolar por aumento do GMP cíclico. O azul de metileno pode ser útil nestas situações, pois inibe a guanilato ciclase e conseqüentemente a vasodilatação, o que resulta em melhora hemodinâmica.JUSTIFICATIVA Y OBJETIVOS: En el período peri-operatorio, el riesgo de anafilaxis siempre debe ser considerado.
