| 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 technology
of Novozymes AS and Danisco AS largely focuse on the development of enzyme. Conclusions: The rapid development of American
bio-ethanol technology benefits from support of American government and it also proves that a high conversion rate of American
basic science. |
