Purpose/Significance] With the globalization of the economy and the advent of knowledge economy, non-practicing entities are rising and developing gradually. Patent litigation is an important strategic instrument of non-practicing entities. The objective of this study is to investigate the patents that non-practicing entities would be interested in, the characteristics of patents that they would consider valuable, and the difference between patents under litigation or not. This study also provides a reference to the patentee for the management and the optimization of its own patent portfolio,has great significance for the enterprise management of its own intangible assets and patent layout strategy. [ Method/Process] From the RPX database, this paper selected 1080 non-litigated patents and 231 litigated patents of 15 non-practicing entities. This paper collected patent information through USPTO, and the relationship between the patent characteristics and the patent value is studied and the empirical analysis is carried out. [ Result/Conclusion] Non-litigated patents and litigated patents have different characteristics. Technical coverage has a negative impact on the value of patents, and the number of claims and the number of ex-isting technologies have a positive impact on the value of the patent. In addition, the impact of different patent characteristics on the value of the patent is different.%[目的/意义]随着经济全球化和知识经济的到来，非专利实施实体逐渐兴起和发展。专利诉讼是非专利实施实体的一个重要的策略工具。为了讨论非专利实施实体感兴趣的专利，哪些专利的特征将是有价值的，而有无诉讼的差异点又是哪些。该研究也为专利权人管理和优化自身专利组合提供参考，对企业管理自身的无形资产和专利布局战略具有重大意义。[方法/过程]从RPX数据库中选择了15家非专利实施实体公司的1080件非诉讼专利和231件诉讼专利为研究对象，通过USPTO收集专利信息，研究专利特征和专利价值间的相互关系，并进行了实证分析。[结果/结论]诉讼专利和非诉讼专利具有不同的特征。技术覆盖范围对专利价值有负向影响，而权利要求数和现有技术数对专利价值有正向影响。此外，不同的专利特征对专利价值影响程度不同。
