随着技术构成的复杂化,技术标准涉及的必要专利迅速膨胀,形成了重叠交织的专利群。以WCDMA标准及其必要专利为研究样本,采用Ucinet6.0软件,以中心度为测度指标,分析技术标准涉及的专利权人的专利引用网络。研究表明,专利权人之间存在紧密连接、高凝聚力的专利引用网络,少数专利权人对网络内专利引用关系具有控制作用,高被引专利权人是专利引用网络形成的基础,在技术标准创立过程中发挥着重要作用。
With the increasing complexity of technology, essential patents involving technical standards are growing rapidly, forming overlapping patent clusters. Taking WCDMA standard and its essential patents as the research sample, the patent citation network of assignees related to technical standards is measured with centrality index by using the software of Ucinet 6.0. The re- suits show that there is a closely connected network with high cohesion among the assignees related to technical standards. A small number of assignees have the control over the citation relationship. Highly cited assignees are the formation basis of the ci- tation network and play important roles in the standard setting process.
