摘　　要：基于德温特创新索引国际专利数据库(DII),利用Thomson Data Analyzer(TDA)、Thomson Innovation(TI)等专利分析工具和平台,对生物质能国际专利进行深入分析,系统客观地揭示了生物质能技术的研发现状、专利技术分布、研发热点以及竞争格局。数据分析结果显示:生物质能相关专利从2005年之后申请量开始快速增长。专利数量排名前三位的国家依次为中国、美国和日本,其专利数量占到全部专利总量的73.52%。从专利平均被引次数可以看出,我国专利整体质量较差。专利数量排名前三的机构分别是广州迪森热能技术股份有限公司、中国石油化工股份有限公司和清华大学,均为中国的企业或科研机构。从研发热点可以看出,2010年以来生物质能专利技术主要研发热点为炉排、储罐及管道、生物质燃气、燃烧室、基因改良、燃料乙醇、生物柴油反应器等。Based on Derwent Innovations Index（ DII） of ISI Wo K,patent analysis tools and platforms such as Thomson Data Analyzer（ TDA） and Thomson Innovation（ TI） etc. were used for deeply analyzing international patent of biomass energy,systematically and objectively revealing the present situation of research and development,the distribution of patent technology,research and development hotspot,as well as the competitive landscape of biomass energy technology. The results showed that the number of patents was increasing rapidly from 2005. China,American and Japan ranked the top 3 of the number of patents.However,by the comparison of average cited times of patent,the results showed that the quality of Chinese patents was poor. The patentees of top three were Guangzhou Devotion Thermal Technology Co.,Sinopec Corp. and Tsinghua University. All of them came from China. The research and development hotspot of biomass energy technology were the boller,biodiesel reaction,ethanol production,gene modification and synthesis gas after 2010.
