利用Orbit专利数据库对国际中药失效专利进行检索,采用定性与定量的分析方法从申请国家,专利申请量,失效专利类型、数量和所占比例,机构排名,机构综合比较等几个方面对中药失效专利进行分析。中国中药失效专利数量最多,韩国的中药专利失效率最低,日本中药专利未被授权占比最高。中国企业集中申请集中失效,专利的维持期限较短,而国外企业专利失效数量分布则比较均匀。科研机构的中药相关专利申请质量较高。我国中药专利发展与其他国家相比起步较晚,发展较为缓慢,存在失效专利数量较多,专利质量较低的问题,急需提高我国中药领域国际竞争力。

Orbit Patent Database was used to search the international herbal invalid patents, using qualitative and quantitative analysis methods to analyze application countries, patent applications, patents, several aspects of the invalid type, number and proportion, institutional rankings, and institutional comprehensive comparison. The number of Chinese materia medica (CMM) invalid patents is the largest, and the invalid rate of Korean herbal patent is lowest. Unauthorized proportion of Japanese herbal patent is the highest. Chinese enterprises are gathered on applying then gathered on invalid, remaining for a short period to maintain the patent, and the patent invalid number of foreign companies is more evenly distributed. CMM research institutes patent applications related to a higher quality. The beginning of the traditional Chinese patent development is later than that of other countries, and the development is relatively slow. There is a problem of higher number of patents invalid patent, low patent quality, and there is an urgent need to improve the international competitiveness of CMM fields.
