专利实质审查周期的影响因素

Factors Analysis on Period of Patent Substantive Examination

本文从专利申请自身特征的视角出发,分析影响专利实质审查周期的微观因素。随机选取2001—2010年在中、美、日三国申请并获得授权的专利族为样本,构建两水平模型分析技术领域、申请人特征、专利文献特征与专利实质审查周期之间的关联。结果表明:专利实质审查周期不仅与技术领域关系密切,而且与申请人的国籍、权利要求数、引用数量、申请途径显著相关。研究成果一方面对政府在完善专利申请制度、健全审查员培训制度以提高实质审查效率方面具有借鉴意义,另一方面对专利申请人如何缩短实质审查周期、获得更快的专利授权具有指导意义。

The paper analyzed the micro factors which affect the period of patent substantive examination from the features of the patent application itself. It selected patent family randomly which applied in China, the United States and Japan from 2001 to 2010 as the sample. It constructed two-level model to analyze the correlation between the technical field, the characteristics of applicants, the features of patent document and the period of patent substantive examination. The results show that patent substantive examination period related closely not only with the technical field, but also with the applicant＇s nationality, the number of claims, the number of references, the type of applications. The research results can provide a reference for improving the system of patent applications, using patent examination of policy tools reasonably, and sounding examiner training system to improve the efficiency of the substantive examination. On the other hand, the results can provide guidance on how to be authorized faster.
