Fluorine Wins PVDF Patent Case as Supreme Court Rejects Solvay's Re-examination Application!

[Beijing, September 6, 2025] Recently, the years-long PVDF patent dispute between Zhejiang Fluorine Chemical New Material Co., Ltd. (hereinafter referred to as "Fluorine") and Solvay Specialty Polymers Italy S.p.A. (hereinafter referred to as "Solvay") has reached a final conclusion. The Supreme People's Court rejected Solvay's application for retrial, confirming that Fluorine does not infringe upon the patent.

The case was initiated by Solvay, which accused Fluorine of infringing its invention patent numbered 200880019571.2 and titled "Copolymer of Vinylidene Fluoride". Solvay demanded that Fluorine cease manufacturing, selling, and offering for sale the model Zheflon® FL2100 PVDF products, and claimed compensation for economic losses and reasonable expenses.

The case went through first-instance and second-instance proceedings. The Supreme People's Court clearly stated in the second-instance final judgment that Fluorine's products did not fall within the scope of Solvay's involved patent rights and thus did not constitute infringement.  Solvay disagreed with the final judgment and subsequently applied to the Supreme People's Court for a retrial. After adjudication, the Supreme People's Court found the reasons for retrial unfounded and rejected the application according to law.

Fluorine stated that it would continue to focus on the research, development, and industrialization of high-performance fluorine materials to provide global customers with better products and services.
