对丁腈橡胶专利的发展总体趋势、技术来源和目标市场、创新主体及其专利布局、创新主体间竞争和合作关系等内容进行了分析。结果表明:德国是丁腈橡胶领域主要的技术来源国;德国朗盛公司和日本瑞翁公司作为两大创新主体,其全球专利战略涵盖了专利布局、合作申请以及专利转让与许可等多种内容,专利竞争激烈。中国是全球第四大市场,近几年来发展势头迅猛,但创新力量分散、研发规模小、关键技术靠引进、海外专利布局基本为零等技术现状不容忽视。建议从行业层面制定专利发展战略,提高中国企业核心竞争力。
The overall trend of patent development of nitrile rubber, the source of technology and target market, the main body of innovation and its patent layout, the competition among innovation subjects and the cooperation relationship were analyzed. The results show that Germany is the main source of technology in the field of nitrile butadiene rubber (NBR). LANXESS and Nippon Zeon are two major innovations. Its global patent strategy covers various aspects such as patent layout, cooperation application, patent transfer and licensing Patents are fiercely competitive. As the fourth largest market in the world, China has enjoyed rapid development momentum in recent years. However, technological innovations such as scattered innovation, small scale of research and development, introduction of key technologies and basically zero overseas patent layout can not be ignored. Proposed from the industry level to develop patent development strategy to improve the core competitiveness of Chinese enterprises.
