摘要
专利法律状态信息分析可以弥补专利申请信息分析的不足,对技术差距、研发实力和专利质量等多方面都能进行深入的揭示。基于专利授权率、授权专利有效率和有效专利维持时间三个指标构建技术、技术来源国或地区、申请人三个维度的专利法律状态信息组合分析模型,揭示专利数量无法展现的相对竞争态势,并以锂离子电池领域进行实证研究。
By complementing the patent application information analysis, patent legal status information analysis deeply reflects the technology gap, research and development（R＆D） strength and patent quality. Based on three indexes of patent licensing rate, authorized patent efficient and effective patent holding time, this paper establishes a portfolio analysis model of patent legal status information from three perspectives of technology, source countries/regions and assignees, which reveals the relative competitive situation hidden by the number of patents. Furthermore, an empirical analysis with this model is presented on the technology of Lithium ion battery.
