摘要
[目的／意义]核心专利的发现是技术创新的重要环节，对于技术改进和专利战略布局意义重大。[方法／过程]首先界定核心专利的概念，然后在对原始PageRank算法模型介绍的基础上，结合专利的被引次数和专利的年龄对原始的PageRank算法进行改进，提出PatentRank算法（简称PTR），并将其应用到OLED领域中来识别核心专利。[结果／结论]研究发现，相比被引次数，PTR不仅能将该领域的核心专利识别出来，而且还可以识别出一些重要性的基础性专利，为研究OLED相关技术提供追本溯源的研究思路；相比原始PageRank算法，PTR具有更高的值区分度，在局部改善了PR的排名。
[ Purpose/significance] The discovery of core patents is an important part in technological innovation, which is of great significance to the technological improvement and the patent strategy layout. [ Method/process] This paper firstly defined the concept of core patent. Then, by introducing the original PageRank algorithm model, the improved PageRank PatentRank （ referred to as PTR） was put forward, which combining the cited times of patents and the patent age. Finally, we applied the new model to the field of OLED to identify the core patents. [ Result/conclusion] We find that compared with the cited times, PTR can not only identify the core patents but also some basic important patents which provide the research ideas for the research of OLED technology. Besides, compared with the original PageRank algorithm, the values of PTR have higher degree of differentiation, and it can improve the PR results on the local scale.
