Abstract
This article attempts to explore such a question that what type of patent portfolio strategy should firms adapt to improve their innovation performance? Regarding the impacts of patent portfolio strategies for innovation, the extant literature holds conflicting views. This study analyzes the relationship between patent portfolio strategies and innovation performance and examines the moderating effect of heterogeneous technical standards. First, the research model introduces two variables: patent portfolio strategy and innovation performance, to explore the relationship between them. In the second step, two the heterogeneity of technical standards are introduced into the original model as a regulating variable to analyze the different innovation performance of different invention portfolio strategies in different situations. Based on the heterogeneity of technical standards, this paper divides into four scenarios to explore the relationship between invention patent portfolio strategy and innovation performance. By studying the patents of 159 Chinese firms in 11 industries from 2010 to 2019 and analyzing the cross-sectional data of technical standards and firm innovation performance, using Stata software and multiple linear regression model, this research finds that (1) a patent portfolio that focuses on a narrow range of technical areas is more beneficial for firm innovation in comparison to a diversified one.
