无线充电领域专利竞争态势分析

Analysis of the patent competition situation in the field of wireless charging

通过对无线充电领域技术专利的统计分析,包括对专利地区分布、专利权人、专利分类号及高被引专利的分析,研究了全球无线充电领域的专利竞争态势,客观地揭示了全球无线充电技术的研究状态以及我国在该领域中的研究现状和地位。并通过构建专利权人-分类号隶属网络进一步分析了企业之间的竞争关系和核心技术领域。研究结果显示,无线充电领域专利多集中在美国、韩国、日本等国家,中国的专利数量多集中在台湾地区。丰田、索尼、三星等企业在专有技术因子上的负载值很高,专利技术与无线充电领域更为密切,在核心技术创新方面具有较强竞争优势。庞巴迪运输公司、沃达丰公司、罗克韦尔国际公司在通用技术因子上的负载值很高,专利技术的通用性强、适用范围广泛,在技术应用领域竞争优势明显。

The patents in the world ＇ s wireless charging field were statistically analyzed mainly in the aspects of patent distribution, patent owners, classification numbers and highly cited patents to investigate the global patent competi-tion situation in the field, so as to reveal the real status of the research on wireless charging techniques as well as China＇ s level in the field.Meanwhile, the competition between enterprises and the core technologies in wireless charging were further analyzed through constructing the affiliation network between the patent owner and the classifi-cation number.The results show that most of the wireless charging patents concentrate in the United States, South Korea and Japan, and Chinese patents mostly concentrate in the Taiwan Region.The companies of Toyota, SONY and Samsung have the very high load value on the proprietary technology factors, and the companys＇ patents are closely related to the field of wireless charging, with the strong competitive advantage in the core technology innovation. The companies of Bombardier transportation, Vodafone, Rockwell International have the very high load value on the general technical factors.The companys＇ patent have the good versatility, broad scope, possessing obvious compet-itive advantage in the field of technology application.
