In a significant move to enhance the coordination and effectiveness of patent enforcement in China, the China National Intellectual Property Administration (CNIPA) and the Shanghai Intellectual Property Administration recently held a joint hearing session at the Shanghai Intellectual Property Protection Center.
This landmark event signals growing synergy between patent invalidation and infringement adjudication processes, which is critical to building a stronger, more unified IP enforcement system.
The Cases at the Center of the Joint Hearing
The session focused on two invention patents:
“Electric Vacuum Pump for Use in Vehicles”, and
“Power Converter and Its Manufacturing Method”.
The CNIPA presided over the patent invalidation proceedings, while the Shanghai Intellectual Property Administration conducted the administrative adjudication of patent infringement disputes concerning the same patents. Legal enforcement officers from various Shanghai districts were invited to attend and observe, highlighting the session's importance as a practical training and demonstration case.
Integrated Approach to Patent Disputes
This joint hearing showcased a coordinated approach to handling the dual dimensions of patent enforcement:
1. Validity – determining whether a patent should be upheld or invalidated.
2. Infringement – determining whether the patent has been violated by a third party.
Each panel participated in the other’s hearings, improving mutual understanding and aligning interpretations of patent claims and technical features.
The result: a more accurate determination of the scope of protection, faster resolution of disputes, and greater consistency between patent examination and enforcement.
Role of Technical Experts
Further reinforcing the quality of decision-making, a CNIPA patent examiner from the Electrical Division acted as a technical investigator, assisting the infringement adjudication process. This ensured that the hearing panel could fully grasp the technical background of the patents, and reach decisions based on a precise understanding of the relevant technologies.
Toward a More Robust Enforcement Framework
This initiative is part of a broader strategy to improve the administrative adjudication system under China’s evolving IP framework. The Shanghai IP Administration has reaffirmed its commitment to:
Implement the Patent Law Implementing Regulations,
Enforce the CNIPA–Ministry of Justice Opinion on Strengthening Patent Dispute Resolution, and
Establish a long-term coordination mechanism between patent granting/validity and infringement enforcement.
These efforts aim to make Shanghai’s patent protection environment more predictable, transparent, and business-friendly—essential for attracting innovation and investment.
Conclusion
This case sets an important precedent for the future of IP protection in China, especially as patent litigation increases in complexity and cross-agency collaboration becomes essential.
By strengthening coordination between agencies and embracing technical expertise, China is taking meaningful steps toward closing the gap between IP law in theory and IP protection in practice.
For businesses operating in China or entering the Chinese market, this development is a positive signal. It demonstrates not only China’s commitment to improving enforcement but also the country's readiness to create an international-standard IP environment.
