French Supreme Court Ruling Paves the Way for Market Access for Coorstek Bioceramics’ Orthopedic Hip Components
CoorsTek Bioceramics/US, a leading supplier of implantable ceramic components for orthopaedic devices, has further established its right to market and sell its pink ceramic hip components in the European Union after the French Supreme Court ruled in favor of CoorsTek in its trademark dispute with CeramTec GmbH/DE. CeramTec initially brought suit against CoorsTek Bioceramics in 2013, alleging trademark infringement based upon CoorsTek’s marketing of its Permallon® (formerly CeraSurf-P) pink ceramic hip components. CoorsTek counterclaimed for cancellation of the trademarks. CoorsTek Bioceramics Permallon® Tru material contains a chromium oxide additive for improved performance, including increased hardness and wear performance. The pink coloring of components manufactured from Permallon® Tru is a natural byproduct of the additive.
Following a ruling by the Court of Justice of the European Union (CJEU) in June 2025, the French Court of Cassation (Cour de cassation) upheld the cancellation of the three CeramTec trademarks by the Paris Court of Appeal. The court found that Ceramtec had registered the trademark for its pink components with the intention of blocking competitors from entering the market. The court also found that CeramTec knew at the time of the trademark application that the pink color achieved by adding chromium oxide contributed to the material’s strength and was not merely a trademark feature.
This case follows on the recent decision by the U.S. Supreme Court to decline review in a similar legal action. By declining review, the U.S. Supreme Court effectively ended CeramTec’s efforts to claim trademark rights to the color pink for ceramic hip components in the United States.
