目的:通过分析非小细胞肺癌(NSCLC)相关国内外中药发明专利申请数据,了解NSCLC相关中药专利研发现状。方法:以关键词和IPC分类号在中国专利文摘数据库、德温特世界专利索引数据库进行检索,获取NSCLC相关国内外中药专利申请文献,并对其整体态势和技术内容进行分析。结果:研究共纳入NSCLC相关中药国外发明专利47件,国内发明专利164件。国内专利申请逐年增多,申请量以山东、江苏、北京等省市居多,大专院校和企业是国内申请人的主要类型,技术领域以中药为主,中药组合物、中药提取物、制备方法是主要发明内容;国外专利申请处于零散状态,申请地域以韩国、美国、日本申请居多,企业是国外申请人的主要类型,近半数专利为多个申请人共同申请,技术领域涉及中药、食品、化妆品等,中药提取物是国外专利主要主题类型。结论:中国NSCLC相关中药专利质量相对较低。应加强知识产权从业人员培养,提升专利质量;提升创新主体专利布局意识,拓展研发领域,加强合作,培育优势创新主体。

Analysis of the Patents of Traditional Chinese Medicine Inventions Related to Non-small Cell Lung Cancer at Home and Abroad

To understand the status quo of the traditional Chinese medicine patents by analyzing the patent application data of non-small cell lung cancer(NSCLC)at home and abroad.Methods:In order to get the patent application documents for traditional Chinese medicine of NSCLC, and analyze the overall situation and technical content, this study used keywords and IPC classification to search in the Chinese Patent Digest database and Derwent World Patent Index Database.Results:There were 47 overseas and 164 domestic invention patents of Chinese medicine enrolled in this study.The number of domestic patent applications has increased year by year.Most of these applications were from Shandong, Jiangsu, Beijing, and other provinces and cities.The main types of domestic applicants were colleges, universities, and enterprises.Chinese medicine was the majority in the technical field.The principal contents of inventions were Chinese pharmaceutical compositions, Chinese herb extracts and preparation methods.Overseas patent applications were still at the fragmented states and most of these applications were from South Korea, the United States, and Japan.Enterprises were the main kinds of overseas applicants.Half of these patents were the joint projects from multiple applications.The field of technology involved traditional Chinese medicine, foodstuffs, cosmetics, etc.Chinese herb extracts were the main types of overseas patents.Conclusion:The quality of Chinese medicine about NSCLC in China is quite low.Therefore, it is necessary to cultivate the staff of intellectual property, improve the quality of patents, enhance the awareness of the layout of patents for innovative entities, expand the fields of research and development, facilitate the cooperation, and foster the superior innovating entities.
