法匹拉韦药物全球专利布局与研发态势分析
Patent Portfolio Analysis of Favipiravir Based on Patent Bibliometrics
鉴于法匹拉韦对于新型冠状病毒肺炎的潜在疗效,该文对该药物的专利布局态势进行分析,反映药物全球专利布局格局,揭示我国在该药物研发上的专利布局特点和壁垒,为我国药物研发攻关以及宏观决策提供支撑。该文利用专利数据,基于专利计量分析方法,从法匹拉韦专利布局时间分布、逐年专利布局技术方向、逐年专利申请国家分布、各国专利技术布局方向分析、专利申请人分析、在华专利布局情况分析以及对华专利许可情况分析几个角度展示了法匹拉韦药物的专利布局态势。研究发现法匹拉韦的基础核心专利由日本掌握,我国相关专利布局时间相对较晚,且以制备工艺和制剂类专利为主,基础化合物专利布局力度较弱,需要适度强化。
Favipiravir has a potential therapeutic effect on COVID-19. To provide support for drug research and development in China and macro decision making, this paper analyzes the patent portfolio of Favipiravir, reflects the global patent application trend, reveals the patent barriers faced by our country in the research and development of the drug. Based on the patent data and the method of patent bibliometrics, this paper shows the patent portfolio of Favipiravir from the following aspects: time distribution of patent application, technology direction of patent application year by year, country distribution of patent application year by year, technology direction of patent application in various countries, patent applicant analysis and patent licensing to China. It is found that the basic core patents of Fabiravir are controlled by Japan, the application time of related patents in China is relatively late and the manufacturing process and preparation patents in China are the main, while the application of basic compound patents is weak, which needs to be moderately strengthened.
