中药提取物专利分析及创新趋势研究

Analysis on patents of Chinese materia medica extract and their innovation trends

通过分析全球中药提取物专利数据,揭示中药提取物研究的发展情况和创新趋势,为行业发展提供参考。基于Innography平台,对中药提取物全球专利进行检索和统计分析,从专利权人分布、地区分布、技术热点主题,专利强度以及专利侵权风险等角度进行深入解读,并以红豆杉为例进行了专利文本聚类分析。全球中药提取物研究总体呈上升趋势,专利申请主要集中在中国、日本、韩国和美国。美国企业综合实力最强,高价值专利量最多,在红豆杉提取物技术中处于优势地位。近年来美国专利诉讼量有所下降,大部分诉讼原告是科技型中小企业。文本聚类结果显示红豆杉提取物涉及了化学合成技术。近几年我国中药提取物专利申请量飞速增长,但申请人分布比较分散,高质量专利的申请量明显弱于美国、日本等国家。国内企业要充分利用现代科学手段不断挖掘中药新的有效成分和提取新工艺,从根本上提高中药提取物行业的竞争力。

By analyzing the patent data of Chinese materia medica（CMM） extracts, the development situation and the trend of the industry were revealed and the suggestion for the industrial development in China was provided. Based on the Innography platform, the global patents of CMM extracts were retrieved and analyzed. The applicant and region distribution, technical hot topic, patent strength, and patent infringement risk were studied. Moreover, taking Taxus baccata as an example, the patent text clustering was carried out. The global herbal extract technique presented a rising trend. Patents were mainly applied in China, Japan, South Korea, and America. America had the most powerful comprehensive company and the largest amount of the high value patents, being in the advantage position in the technology of T. baccata extraction. The patent litigation number had declined recently and the most of plaintiffs of the litigations were technological medium and small-sized enterprises. Text clustering results showed that the extraction of T. baccata involved synthetic techniques. In recent years, the patent quantities of CMM herb extracts in China have increased rapidly, but the distribution of applicants was scattered. Additionally, the number of high-quality patents in China was significantly weaker than that in America and Japan. Therefore, domestic enterprises should make full use of modern technique to find new effective CMM ingredient and investigate new extraction procedures, in order to fundamentally strength the industrial competitiveness of CMM extracts in our country.
