以专利侵权诉讼为研究对象，通过以度数中心度、接近中心度、中间中心度、特征向量中心度来表征专利权人之间的诉讼关系，构建了专利侵权诉讼网络。以专利权利人在网络中的活跃程度和积极程度建立了专利侵权诉讼矩阵。并以近5年在美国IT领域发生专利侵权诉讼关系的21家企业为例，运用专利侵权诉讼网络和专利侵权诉讼矩阵综合分析，揭示了企业的市场地位。实例显示该方法有助于企业对自己和竞争对手在市场地位方面的把握、对企业的商业战略规划具有有效的参考价值。%A patent infringement lawsuit means the enterprise's competition for market. Targeting patent infringement lawsuits as the re-search object, a patent infringement lawsuits network is set up with the degree centrality, closeness centrality, betweeness centrality, eigen-vector centrality expressing the relations of the patentees. A patent infringement lawsuit matrix is also established based on the active degree and the positive degree of patentees in the network. Taking the 21 companies involved in litigations in the IT field in the past five years as an example, the paper explores the market position of the companies by the patent infringement lawsuits network and patent infringement lawsuit matrix. The example shows that the methods proposed are useful for enterprises to understand their own and their competitors' posi-tion in the market, and thus provide useful reference to the business strategic planning.
