为了解国外申请人在我国天然药物尤其是复方药物的专利布局特点，采用国家知识产权局自主开发的专利检索与服务系统（Patent Search and Service System of SIPO）的中国专利文摘数据库（CNABS），对1985-2012年5月的不同国家地区来源的专利申请进行检索，以国际专利分类表中涉及植物、藻类、苔藓、真菌等涵盖中药的分类号为检索目标，采用人工及软件辅助分析的方法对检索结果，尤其是中药复方专利进行多角度的分析（包括申请人、治疗领域、重点专利技术），以期掌握中药复方专利申请中的发展态势，并籍此分析国外复方专利技术的布局状况与技术发展路径，为国内专利制度下中药复方产业的长足发展提供参考。

In order to learn about the patent layout features of natural drugs, especially compound Chinese materia medica (CMM) patents in China applied by foreign applicants, the patent applications from the different countries during 1985－May, 2012 were searched and analyzed based on Patent Search and Service System of SIPO. The searches are targeted at the classification numbers of CMM, such as plant, algae, moss, fungi, in the international patent classification. The search results, particularly multi-angle analysis on compound CMM patents, including applicants, therapeutic field, and important patent technology, were analyzed by manpower and assistant software. The results could help us to know more about the development trend in the application of compound CMM patents on which the foreign situation and technology development path of patent medicine will be analyzedso as to provide a strategicvalue for the rapid development of CMM enterprises in China under the domestic patent system.
