边缘计算领域核心专利挖掘-基于专利引证视角

Analysis on the core patent in Edge Computing Technology based on Patent Citations

摘要:

以IncoPat为数据源构建检索策略,采用专利被引频次指标对全球边缘计算领域核心专利进行挖掘,并对该核心专利进行向后引证和向前引证分析,包括被引证年份分布、专利权人分布、技术分布和自引证技术演化路线分析。研究结果表明,美国是全球边缘计算技术最主要的应用国和来源国；核心专利US20110075675A1以年均60.6次被引频次排名第一,其向前引证主体包括IBM、Cisco、华为、NEC和三星电子等,且存在创新竞争关系；边缘计算技术演化路线由早期的边缘呼叫和会话管理,逐渐演化到分组路由和无线承载标识,并最终过渡到智能路由和无线设备监控策略研究。

Abstract:

Retrieval strategy is constructed with IncoPat, the core patent in global edge computing is explored by quantities of patents cited, by which the patents backward cited and forward cited are analyzed, including the distribution of cited year, patentee, technology and the evolution route. Research results show that USA is the most important application and source country in edge computing, the core patent US20110075675A1 ranks the first with 60.6 times of cited quantity, of which the citation entities include competitive corporations such as IBM, Cisco, Huawei, NEC and Samsung Electronics, etc., the evolution route of edge computing technology has evolved from early edge call and conversation management to points Group routing and wireless bearer identification, and finally transition to intelligent routing and wireless device monitoring strategy research.
