核心专利识别指标理论与实证研究

Theory and Empirical Research on Core Patent Identification Indicators

核心专利在产业中具有重要的地位,专利可以划分为核心专利、基本专利、外围专利和重要专利等术语。本文总结归纳了核心专利的特征以及定义,进而,以福建省新能源汽车技术领域为专利数据样本,利用多元回归模型实证分析核心专利识别指标对核心专利的影响效应及解释能力,得到权利要求数量、发明人个数、IPC分类号个数、同族专利数量、引证次数、被引证次数和专利转让回归显著性成立,文献页数回归不显著,对于专利转让更多的是关联企业之间的活动,不能代表核心专利的价值指标,研究结果对于核心专利识别具有重要的指导意义。

Core patent plays an important role in the industry,patent could be divided into core patent,basic patent,peripheral patent and important patent.This paper summarizes the characteristics and definitions of core patent,and then takes Fujian's new energy automotive technology field as a sample,using multiple regression models for empirical research,and analyses the impact and explanatory ability of core patent identification indicators on core patent,it is concluded that the regression of the number of claims,the number of inventors,IPC classification numbers,the number of patent families,citation number,cited number and patent transfer are significant,the regression of document pages is not significant,the activities between patent transfer are joint ventures,it could not be represented the value indicator of core patent,the result has important guiding significance for the identification of core patent.
