Abstract

[Purpose/Significance] The research explores the impact of advance disclosure of invention patents applied by listed companies on innovation diffusion at the societal level. It aims to deeply understand the mechanism of early disclosure policy in promoting technological innovation and knowledge dissemination, provide scientific support for improving the patent system and refined intellectual property protection policy, and help promote the effective use of innovation resources and the sustained and healthy growth of innovation activities. [Method/Process] The research took the invention patents of Chinese listed companies as the research object. Based on an in-depth analysis of the data of invention patents from 2003 to 2020, it examined the impact of patent early disclosure on innovation diffusion and the moderating effect of the third amendment to the Patent Law on both. [Result/Conclusion] The research results show that the early disclosure of patents significantly promotes innovation diffusion at the societal level by shortening the time of information disclosure and reducing information asymmetry, especially in the subgroups of patent agencies, non-state-owned enterprises, and high-tech industries. In addition, the third amendment to the Patent Law further enhances the positive impact of early patent disclosure on innovation diffusion by strengthening intellectual property protection.
