【目的/意义】P2P技术作为2000年前后一项重要的技术热点,近20年的发展,其技术成熟度和应用广泛度都获得极大提高,对无线网和计算机技术的发展起到了重要推动作用。【方法/过程】以INNOGRAPHY平台为数据源,对P2P技术国际专利进行检索和统计分析,从专利权人分布、地区分部、技术热点主题,以及专利强度等角度进行深入解读。【结果/结论】随着P2P技术在无线网络和计算领域应用日趋成熟,其技术热度正在褪去,其专利申请数量近三年呈下降趋势,亟待新的研究热点出现;中国公司在P2P技术上仍属于跟随者,无论资源还是技术实力都有所欠缺,需转换策略,向技术实力型专利权人过渡。
[Purpose / Significance] P2P technology, as an important technology hotspot around 2000, has gained tremendous technological maturity and extensive application in recent 20 years and has played an important role in the development of wireless networks and computer technologies effect. [Method / Procedure] The INNOGRAPHY platform is used as a data source to search and analyze the international patent of P2P technology, and to make an in-depth interpretation from the perspective of patentee distribution, regional division, hot topic of technology, and patent intensity. [Results / Conclusion] With the maturing of P2P technology in wireless networks and computing applications, the popularity of P2P technology is declining. The number of patent applications has been on the decline in the recent three years. Emerging new research hot spots are urgently needed. Chinese P2P technology Belonging to followers, regardless of resources or technical strength are lacking, the need for conversion strategy, the transition to technology-based patentees.
