Recently, the Supreme People’s Court issued Administrative Judgment No. 6131 of 2023, revoking the first-instance judgment and the reexamination decision of the China National Intellectual Property Administration (CNIPA), and ordering CNIPA to reconsider Tsinghua University’s invention patent application titled “Andrias davidianus Cartilage Chondroitin Sulfate and Extraction Method Thereof”.

The core dispute in this case centered on whether supplementary experimental data could be used as a key basis in assessing inventiveness. The Supreme People’s Court clearly ruled that supplementary experimental data shall be considered if the technical effects demonstrated therein are disclosed or implicitly disclosed in the original application documents. This holding not only resolves the specific dispute in the case but also provides important guidance for similar cases in the future.

Throughout the litigation, Caihe’s legal team, acting as counsel for Tsinghua University, maintained a professional, rigorous and efficient approach, fully demonstrating the unique value of the applicant’s technical solution and securing a favorable outcome.

This judgment represents a phased protection of the legitimate rights and interests of the client’s scientific research achievements and reflects the strong support of intellectual property judicial protection for innovation-driven development. Beijing Caihe Law Firm will continue to uphold the philosophy of “Professionalism, Integrity and Efficiency” and provide high-quality intellectual property legal services for universities, research institutions and enterprise clients.
