Innovation of traditional Chinese medicine compounds and patent layout strategy with Lianhua Qingwen Formula as example / 中国中药杂志

ABSTRACT

The innovation and patent layout of traditional Chinese medicine compounds reflects the innovation level of the traditio-nal Chinese medicine industry to a certain extent. Lianhua Qingwen Formula was taken as an example to analyze the innovation and patent layout of traditional Chinese medicine compounds. The study first proposed an innovative technology system for traditional Chinese medicine compounds, and then analyzed the advantages and disadvantages of Lianhua Qingwen Formula in innovation and patent layout based on 56 patents and other relevant patents. The analysis results showed that Lianhua Qingwen Formula had the following characte-ristics in terms of patent layout. In terms of innovation technical route, the patented technical route of Lianhua Qingwen Formula was mainly based on the composition and preparation of granules as the first choice, followed by corresponding process improvements, new uses, and detection methods as the main improvement routes. In terms of the corresponding patent layout, the basic patent protection scope of Lianhua Qingwen Formula completely covered marketed drugs, and then took new functions as the main layout strategy for subsequent patent applications. With the advancement of modern technical means, the preparation process and testing methods have been optimized continuously. At the same time, the international patent layout was given the priority in domestic patent application. Based on the above characteristics, the study gave suggestions for follow-up innovation and patent work for Lianhua Qingwen Formula, so as to provide enlightenment for other traditional Chinese medicine companies in exploring original innovation of traditional Chinese medicine compounds, improving innovative methods, and enhancing the ability of patent layout of innovative achievements.
