抗流行性感冒的传统药物专利信息分析

Patent Information Analysis on Anti-influenza Traditional Medicine

专利文献是一种研究价值很高的科技文献,如今受到越来越多研究者的关注。本文利用《世界传统药物专利数据库》(WTMPD),对世界范围内过去近30年中,传统药物治疗和预防流行性感冒的专利进行了检索,并进一步筛选得到包含2 423件专利的数据集,在此基础上进行了多角度的统计分析,形成了传统药物抗流感专利分析报告。由分析结果可见,在该领域内,国内专利申请量增长迅速,在数量上处于世界领先地位,但是国内申请其他国家专利的数量还比较少。相比之下美国、日本、韩国在中国申请的专利数量比较多。药品生产企业围绕自身产品研发、成果申请了大量优质专利,已成为专利申请的核心力量。金银花、甘草、板蓝根、连翘、黄芩是抗流感专利中使用最多的5种药物。

Patent documentation is a kind of high-value scientific literature, which has caught the attention of more and more scholars. In this paper, the World Traditional Medicine Patent Database （WTMPD） was used to retrieve patents of the traditional medicines used in the treatment and prevention of influenza worldwide in the past 30 years. A total of 2 423 patents were further screened by a series of processes. Finally, multi-angle analysis was carried on the dataset to form a patent analysis report on traditional anti-flu drugs. From the analysis, we found that China had a rapid increase in the number of patent applications, which was in the leading role in the world, though the number of PCT applicant from China is relatively low. A large amount of applicants from the USA, Japan, and Korea have entered into China. Pharmaceutical company is the core group of patent applicant, who had applied a lot of quality patent about their products to protect their commercial interests. Honeysuckle, licorice, isatis root, forsythia and skullcap are five kinds of herbs, which have been most frequently used in anti-influenza patents.
