目的 基于壹專利（Patyee）數(shù)據(jù)庫對近年來中藥的研究專利概況進行可視化分析。方法 從全球專利角度，針對中藥技術發(fā)展概況進行分析，并著重對全球與中國中藥產品中涉及原料藥、成品藥與應用領域的專利申請情況進行分析。結果 全球中藥相關的專利申請量一直處于高申請量的狀態(tài)，地域分布顯示中藥技術的主要來源國和應用國均為中國。其中，中國的中藥專利申請數(shù)量處于絕對優(yōu)勢地位，但有效率較低。全球中藥專利在原料藥、成品藥與應用領域方面，成品藥專利數(shù)量遠超原料藥及應用，中國在各技術分支專利數(shù)量均絕對領先。中國中藥專利在原料藥、成品藥與應用領域方面，成品藥專利數(shù)量最多，其次是應用，原料藥專利數(shù)量最少。結論 雖然目前國內中藥相關技術專利申請體量遠超海外，但是仍面臨專利質量相對不高，海外專利布局不足，原料藥、成品藥與應用領域專利分布不均衡等問題，建議相關創(chuàng)新主體需要更加有針對性地布局研發(fā)，提升創(chuàng)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.
