基于专利计量分析的抗HIV 药物发展趋势研究

近年来,艾滋病感染人数急剧增加,已成为威胁人类健康的重大疾病。为了对抗HIV药物的研究现状和发展趋势进行深入分析,本文通过在Derwent Innovations Index数据库中检索2006-2012年的抗HIV药物专利。对采集的专利信息用TDA软件进行数据清洗,利用专利计量分析方法,借助可视化的分析工具,从专利申请数量、优先权国、专利技术机构和专利技术领域等方面进行分析。研究发现近几年抗HIV药物专利申请数量较为平稳;专利申请主要集中在美国、加拿大和中国;抗HIV药物的技术领域主要集中在天然产物、发酵工业和杂环化合物等方面。美国在专利申请数量方面远远领先于其他国家,足以见美国在抗HIV药物研发的活跃和强劲的技术实力。我国虽然在专利申请数量方面具有一定优势,但是与国外相比仍有较大差距。

Study on Development Trends of Anti-HIV Drugs Based on Patentometric Analysis

In recent years, there is a sharp increase in the number of HIV infections, which have become a major threat to human health diseases. In order to research deeply the status and development trends of anti-HIV drugs, we retrieved the anti-HIV drugs'' patents in the Derwent Innovations Index, and used the TDA to cleaning the data. We used the method of patentometrics by visual analysis tools to analyze patent literatures of anti-HIV drugs on number of patent application quantity, priority countries, patent assignees and technical fields. After analyzing and processing, we found that the number of anti-HIV drugs'' patent applications is relatively stable in recent years; patent applications are mainly in the United States, Canada and China; technical fields of anti-HIV drugs are mainly concentrated in natural products, fermentation industry and heterocyclic compounds. The number of patent applications in the United States is far ahead of other countries, owing strong technical strength. Although China has certain advantages in the number of patent applications, there is still a wide gap as compared with foreign countries.
