目的 基于壹专利（Patyee）数据库对近年来中药的研究专利概况进行可视化分析。方法 从全球专利角度，针对中药技术发展概况进行分析，并着重对全球与中国中药产品中涉及原料药、成品药与应用领域的专利申请情况进行分析。结果 全球中药相关的专利申请量一直处于高申请量的状态，地域分布显示中药技术的主要来源国和应用国均为中国。其中，中国的中药专利申请数量处于绝对优势地位，但有效率较低。全球中药专利在原料药、成品药与应用领域方面，成品药专利数量远超原料药及应用，中国在各技术分支专利数量均绝对领先。中国中药专利在原料药、成品药与应用领域方面，成品药专利数量最多，其次是应用，原料药专利数量最少。结论 虽然目前国内中药相关技术专利申请体量远超海外，但是仍面临专利质量相对不高，海外专利布局不足，原料药、成品药与应用领域专利分布不均衡等问题，建议相关创新主体需要更加有针对性地布局研发，提升创新高度。

Objective Patyee database was used to visually analyze the research patent situation of Chinese materia medica (CMM) in recent years. Methods From the perspective of global patents, this article conduct a detailed analysis of the technological development status of CMM, it delves into patent applications pertaining to active pharmaceutical ingredients (APIs), final products, and the utilization of CMM worldwide, with a particular focus on China. Results The number of patent applications in the global CMM has been in the state of high application volume, and the geographical distribution shows that the main source and application countries of CMM technology are both China. Among them, the number of CMM patent applications in China is in an absolute dominant position, but the effective rate is the lowest among the major applicant countries. The analysis of global patents of CMM in the fields of APIs, finished medicines and applications shows that the number of patents forfinished medicines far exceeds that forAPIs and applications, and China absolutely leads in the number of patents in each technical branch. The analysis of Chinese patents of CMM in the fields of APIs, finished medicines and applications shows that the number of patents forfinished medicines is the highest, followed by applications, and the number of patents for APIs is the lowest. Conclusion Although the volume of domestic patent applications related to CMM far exceeds that of overseas, it still faces problems such as relatively low patent quality, insufficient overseas patent layout, and unbalanced distribution of patents among APIs, finished products and applications, etc. It is suggested that the relevant innovation bodies need to lay out their research and development in a more targeted manner to enhance the height of innovation.
