摘　　要：分析杜仲橡胶(EUG)领域的专利申请趋势、申请人及专利技术情况。EUG领域专利早期申请多为国外企业,但大部分专利已经过期。依托国内丰富的杜仲资源,我国EUG研究比较活跃,主要集中在高校和聚焦杜仲产业的企业以及部分汽车企业,对EUG的研究主要集中在化学结构改性和产业应用方面。EUG领域国外技术壁垒较少,建议国内企业和高校加强合作,在杜仲种植和提取及EUG改性和应用等方面优势互补,形成产业链。In this paper,the trend of the patent application,the applicants and the technical situation of the patents in the field of eucommia ulmoides gum(EUG)were analyzed.Most of the early applications for EUG patents were from foreign companies,but most of the patents had expired.Relying on the rich resources of eucommia ulmoides in China,EUG research in China was relatively active,and mainly concentrated in universities and enterprises focusing on eucommia ulmoides industry,as well as some automobile enterprises.The research on EUG was mainly concentrated in chemical structure modification and industrial application.The foreign technical barriers in the EUG field were relatively low.It was recommended that domestic enterprises and universities strengthen cooperation and complement each other in the eucommia ulmoides planting and extraction,EUG modification and application and other aspects to form an industrial chain.
