美国生物乙醇技术的专利计量分析

目的：对美国的生物乙醇技术的进展进行深入挖掘。方法：以专利计量的分析方法,借助可视化的分析工具,对美国生物乙醇技术的专利文献从技术生命周期、IPC小类重点分布、专利权人专利申请及其技术应用重点进行分析。结果：研究发现近年来美国生物乙醇技术的发展进入了迅速的成长期;技术应用重点集中在微生物发酵、酶解、转基因植物新品种等领域;杜邦公司和先正达公司技术重点集中在转基因新品种的研制,诺维信公司和丹尼斯克公司技术重点集中在生物酶的研制。结论：美国生物乙醇技术发展迅速,这与美国政府的支持有关,也证明美国的基础科学转化率很高。

Patentometrics Analysis on American Bio-ethanol Technology

Objective： To research deeply the progress of American bio-ethanol technology.Methods： We used the method of patentometrics by visual analysis tools to analysis patent literatures of American bio-ethanol technology on technology lifecycle,major distribution of IPC subclass,patent application and its technology focus of patent assignees.Results： After analysis,the author finds out that the development of American bio-ethanol technology has entered into the rapid growth period;the vital application of bio-ethanol technology focused on microbial fermentation,hydrolysis,new varieties of transgenic plants and other fields;the technology of DuPont Company and Syngenta Participations AG primarily focuse on the development of new varieties of genetically modified while the tech-nology of Novozymes AS and Danisco AS largely focuse on the development of enzyme.Conclusions： The rapid development of Ameri-can bio-ethanol technology benefits from support of American government and it also proves that a high conversion rate of American basic science.
