March 25, 2022 (press release) –

Solvay announces today that it has reached an Enforcement Action Settlement Agreement with China-based HySci (Tianjin) Specialty Materials Co., Ltd. on Nov 20, 2021 for a 2015 effective patent infringement judgment made byTianjin 2nd Intermediate People’s Court and further confirmed by the Supreme People's Court in favor of Solvay. The 2015 judgment found Hysci infringing Solvay’s  Chinese patents CN1177764C and CN1039804C, and ordered Hysci to cease producing/selling the infringing products and to make a payment of material damages to Solvay. 

According to the Settlement Agreement reached with Hysci, Solvay’s financial claims against Hysci have now finally been settled.

The terms and conditions of this Settlement Agreement are based on both the 2015 effective patent infringement judgment and the corresponding enforcement court decisions.

Rare earth oxides are used in automotive catalysts to abate noxious gases from engine exhaust. Ever stricter air quality standards require increasingly complex formulated rare earth oxides that are the result of extensive research and innovation programs. Solvay’s OPtalys® and Actalys® product ranges offer tailored solutions for various types of automotive catalysts and contribute significantly to cleaner mobility.

Respect of Intellectual Property Rights is essential for free and healthy competition. Solvay is committed to vigorously enforcing its intellectual property rights against infringers.
