| 文章提出核心专利的识别及可视化方法。经过核心专利组合识别，专利权人名称标准化，专利权人国别处理，该方法提出核心专利的国家全球分析、20 强专利权人全球分析、共专利权人网络分析、高合作子网络全球分析。实验表明，全球锂电池核心专利被美国、日本、韩国主宰，20强专利权人主要分布于北美、西欧、东亚，高合作子网络由 MICHOT CHRISTOPHE、UNIV MONTREAL、PHOSTECH、CENTRE NAT、UMICORE 构成，主要合作在加拿大、美国、欧洲、国际局、中国、韩国、日本。由此可见，核心专利的识别及可视化方法有助于专利分析、专利管理等。 |

| It proposes recognition and visualization methods of core patents. Some methods are applied for the sake of analyzing the core patents: (1) to propose the composition identifi cation of core patents; (2) to describe the standardization of patentees’ names; (3) to discover patentees’ application nation names; (4) to propose global analysis of the application nations of core patents; (5) to propose global analysis of the top 20 patentees;(6) to propose analysis of co-patentee network; and (7) to propose global analysis of the frequent collaboration subnetwork. The simulation results show: (1) it can vividly reveal that the core patents of global lithium battery is dominated by the subsets of research-intensive United States, Japan and Korea; (2) it can help recognize that top 20 patentees mainly come from North America, Western-European and Eastern-Asian; (3) it can exhibit that the frequent collaboration subnetwork consists of Michot Christophe, Univ Montreal, Phostech, Centre Nat,and Umicore; and (4) it can display that primary publication nations of the frequent collaboration subnetwork are Canada, United States, Europe, WIPO, China, Korea and Japan. Thus it can be seen that recognition and visualization methods of core patents may offer help in patent analysis, patent government, etc. |
