基于专利文献计量的广金钱草发明专利信息研究

Study of Patent Information of Inventions of Desmodium Based on Patent Analysis

目的分析广金钱草发明专利的经济信息、法律信息及技术信息,为后续有关研发及发明专利申请活动提供参考。方法检索、筛选1985-2018年的广金钱草中药发明专利,运用专利文献计量法对广金钱草发明专利进行信息挖掘。结果国外申请人主要为日本医药企业,国内近6年才形成重点申请人,主要为武汉与广西医药企业;从人福医药企业的申请经历情况来看,广金钱草难以用专利形式进入日韩、北美市场;同时国内转化为中药新药的几率低,重点授权人发明专利不足以形成专利网等问题。结论经过分析,本研究认为国内广金钱草申请人宜先立足于国内市场,且宜注重围绕"广金钱草提取物提取方法"合成同一中药材不同的提取物进行产品开发,最后不能忽视剂型、治疗适应证及药物配伍方面的覆盖面以及应用创新。
