基于专利的全球微藻DHA菌种选育技术发展态势

Patent-based Development Trend of Global Microalgae DHA Strain Breeding Technology

菌种选育技术是微藻DHA提取的前提和基础,在微藻DHA提取中发挥了关键作用。对其开展专利计量分析,能够为我国DHA生产企业的技术布局以及知识产权战略制定等提供借鉴和参考。本文从专利角度研究了全球微藻DHA菌种选育技术专利的申请数量变化、发明人发展态势、专利技术布局、主要申请机构和菌种选育技术最新动向等。结果表明:近年来,菌种选育技术的专利申请和发明人数量不断增长,在2011年达到了顶峰,技术活跃度和创新度都比较高;杜邦公司、马泰克生物科技公司、巴斯夫植物科学有限公司在微藻DHA菌种选育领域最具有竞争力,这些机构研发各有其侧重点,主要专利保护机构为世界知识产权组织和欧专局;菌种选育领域不断涌现出氨基酸及其衍生物、核酸及其水解物或衍生物、类固醇以及含磷化合物等新技术,新出现的专利技术之间存在较大差异,可见菌种选育技术在不断的拓宽,市场也在不断发展。

The strain selection technique is the premise and basis for the extraction of microalgae DHA,and plays a key role in the extraction of microalgae DHA.The patent measurement analysis of strain breeding technology is expected to provide reference for the technology and layout of Global DHA production enterprises and for the formulation of intellectual property strategies of Global DHA production enterprises.From the perspective of patents,this paper studies the changes in the number of applications for global microalgae DHA strain breeding technology patents,the development trend of inventors,the layout of patent technology,the latest trends of major applicant institutions and strain breeding technology.The results show that in recent years,the number of patent applications and the number of inventors of the breeding technology have increased,reaching a peak in 2011,and the technical activeness and innovativeness are relatively high;Du Pont,Martek Biotech,BASF Plant Science Company are the most competitive in the intellectual property protection of microalgae DHA strain breeding technology,and each of these institutions has its own focus.The main institutions providing inteuectual protection are the World Intellectual Property Organization,the European Patent Office and the United States.New technologies such as amino acids and derivatives,accounting and hydrolysates or derivatives,steroids and phosphorus-containing compounds have emerged in the field of strain selection.It is found that there are large differences in emerging patent technologies,and the breeding techniques of strains are in continuous expansion,and the market is constantly developing.
