基于技术多样性的专利申请人与审查员的引证行为差异

近年来，专利引文越来越多地被用于技术路径研究、技术会聚、技术扩散等技术领域间的知识活动研究，但并未有效区分申请人引用和审查员引用，现有技术领域层面对申请人和审查员引用差异的对比研究还停留在较为浅显的统计层面。将技术类别间的差异性引入到申请人引用和审查员引用的对比研究中，在技术类别分布基础上，探究专利技术类别多样性视角下申请人引用和审查员引用的知识来源差异，并对其开展相关性分析。研究结果表明:专利申请人引用涉及的技术类别范围更广，而审查员引用则更集中于本技术类别；对大部分技术类别，申请人引用的技术类别多样性要高于审查员引用，但两者呈现出显著的正相关性。

Citation Behavior Differences between Patent Applicants and Examiners from the Perspective of Technology Diversity

In recent years, patent citations have increasingly been used to study the knowledge activities between technology fields, such as technology path research, technology convergence, and technology diffusion. But they haven''t effectively distinguished applicant citations and examiner citations. Previous studies on the differences between applicant cit ations and examiner citations from, the technical field level have remained at a relatively low statistical level. In this paper, based on the distribution of technical categories, discrepancy between the technical categories themselves was introduced into the study to explore knowledge sources from the perspectives of the diversity of technical fields of applicants and examiners, respectively. The results showed that applicant citations covered more technical fields, whereas examiners were more focused on the fields that they were familiar with, and the diversity of applicant citations in most technical fields was higher than that of examiner citations. Further, it was found that there was a significant positive correlation between applicant citations and examiner citations in both aspects.
