Abstract:

The biological breeding is helpful to avoid food crisis brought by natural disasters or plant diseases and insect pests. Based on Derwent Innovations Index (DII) of ISI WoK, this paper analyzed the patent literature in biological breeding technique using TI, TDA, etc. tools; and systemetically revealed the present R & D status of biological breeding technology, its hotspots and technological distribution. The result showed that the United States had obvious advantage in the field of biological breeding technology; China took the second place in quantity requested for patent in biological breeding field, but generally the patent quality was not high. Although Pioneer Hi-bred, Monsanto and other international breeding giant enterprises all set up patent layout in the major countries, There were no Chinese enterprises ranked in the top 10 patentee. The above results provided reference meanings for the development and distribution of biological breeding in our country.

Key words: biological breeding technique, proprietary technology, situation analysis

摘要：

生物育种技术的发展有助于减少或者避免由于自然灾害或病虫害带来的粮食危机等问题。基于德温特创新索引国际专利数据库（DII），利用TDA分析工具对生物育种技术领域专利文献进行分析，系统揭示了生物育种技术的研发现状、热点以及技术布局。结果显示，美国在生物育种领域技术优势明显，我国在生物育种领域专利申请量排名第二，但专利总体质量不高；杜邦先锋种业、孟山都等国际育种巨头企业均在主要国家都进行了专利布局，而排名前十位专利权人中没有中国企业。该研究结果对我国在生物育种领域的发展和布局具有一定借鉴意义。
