Скачать или смотреть Latest Challenges of Patent Invalidation Proceedings in China

This presentation provides a strategic overview of recent developments in China's patent invalidation proceedings. It begins with an introduction to the system's defining features: its efficiency, cost-effectiveness, and relationship with Chinese-language prior art. The discussion then focuses on two major evolving areas under revised guidelines effective January 1, 2026, respectively regarding "strawman" requests and expansion interpretation of the principle of res judicata. Practical case studies illustrate how these proceedings are used as leverage in global IP disputes and how panels investigate suspicious petitions. The overarching message is the growing strategic importance and increasing procedural rigor of China's invalidation system, demanding proactive adaptation from all parties involved.
