智能手机触摸屏专利分析

摘要

Touchscreen patents are the focuses of the smartphones “patent race”. The patent retrieval and patent analysis can reveal the distribution and competitive advantage of touchscreen patents. This paper uses Derwent Innovation Index to search and analyze smartphone touchscreen patents from aspects such as the application date, patent concentration and patentees. It is found that the touchscreen patent concentration shows an inverted U-shaped curve; touchscreen patent has a trend of being fragmented in recent years;Apple has more ad-vantages in the quality of touchscreen patents.%触摸屏专利是智能手机领域“专利竞赛”的焦点。专利检索和分析能够揭示触摸屏专利的分布状态和竞争优势。利用德温特专利数据库对智能手机触摸屏技术进行专利检索，从申请时间、专利集中度和专利权人等方面进行分析。专利分析显示触摸屏专利集中度呈现倒U型曲线，触摸屏专利近年来具有分散趋势，苹果公司在专利质量方面更具优势。
