国际网球专利技术领域竞争情报的可视化分析

The Visual Measurement Analysis of Competitive Intelligence in the Field of International Tennis Patent

利用文献计量可视化软件Bibexcel、Ucinet 6.0和Citespace II对从2002—2012年收录在《德温特创新索引》专利数据库的2 085篇网球专利文献进行了计量分析,并以可视化图谱的形式展现出网球专利文献的时间、专利权人、发明人、技术热点等指标的分布特征。研究结果显示,近十年间国际上网球专利的年度申请量整体上呈波浪式上升趋势;研究领域主要集中在仪器、体育科学、工程设计、化学、材料科学、计算机科学、建筑工程学等18个学科领域;专利权人主要集中在美国和日本的一些大型企业;专利的技术热点主要集中在网球器材、比赛设备、服装以及计算机电子等领域;核心专利和重要发明大都集中在美国和日本等发达国家。

This study, with the latest bibliometric and Citespace II, analyzes the 2 085 tennis patent visualization software Bibexcel, Ucinet 6. 0 literature from 2 0 0 2-- 2 012 included in the Derwent Innovation Index patent database, and via visualization map showing the time, the pa- tentee, inventor, technology hot spot indicators distribution characteristics. The results show that nearly a decade on the international tennis patent applications for the year as a whole wavy upward trend ; research areas are mainly concentrated in the instrument, sports science, engi- neering, chemistry, polymer materials science, rrlaterials science, computer science, architecture etc. including 19 disciplines;patentee mainly large enterprises in the United States and Japan; patented technology hot spots mainly in the field of tennis equipment, game equipment, clothing and computer electronics ; the core patent and important inventions are concentrated in the the United States and Japan and other developed countries.
