医药日化领域植物提取物的日韩专利态势分析

Analysis of Japanese and Korean patent situation of plant extracts in pharmaceuticals and daily chemicals

选择德温特创新索引为专利数据源,检索1994—2022年在日本和韩国公开的德温特手工代码为B04-A10(植物提取物)且国际专利分类为A61(医学、卫生学)的专利,得到日本专利19874件、韩国专利25214件,并从专利申请趋势及同族专利分布、专利申请人及其合作网络、企业的技术聚焦、专利主题词分析4个方面进行分析与可视化。日韩在植物提取物的专利规模大致相当;日本的国际化程度较高但近年申请专利数量逐渐减少,申请者以企业为主;韩国近几年的植物提取物专利势头正旺,申请者以大学和研究院所居多;日本更侧重于植物提取物在化妆品、护肤品等日化产品的创新研发,而韩国更侧重于医药配制品等药用领域的创新研发。通过对两国医药日化领域植物提取物的新兴企业和前沿主题词的分析,为我国的相关专利技术研发和创新提供参考。

The Derwent Innovation Index was selected as the patent data source to search for patents with Derwent manual code B04-A10(plant extracts)and international patent classification A61(medical,hygiene)disclosed in Japan and South Korea from 1994 to 2022.A total of 19874 Japanese patents and 25214 Korean patents were retrieved.It was analyzed and visualized from four aspects of patent application trends and distribution of patent families,patent applicants and their collaboration networks,technology focus of companies,and patent subject terms.The number of patents on plant extracts in Japan and South Korea is roughly comparable.Japan is more international but has seen a gradual decline in patent applications in recent years,with the majority of applicants being companies;Korea has seen a boom in plant extract patents in recent years,with the majority of applicants being universities and research institutes;Japan focuses more on the innovative research and development of plant extracts in cosmetics,skin care products and other daily products,while Korea focuses more on the innovative research and development of medicinal products such as pharmaceuticals.Through the analysis of the emerging enterprises and cutting-edge theme words of plant extracts in the field of medicine and daily chemical in the two countries,the reference is provided for the research and development and innovation of related patent technologies in China.
