Beijing, China – February 18, 2019 --- Solvay announced today on behalf of its wholly owned subsidiary, Cytec Industries Inc., and its Polymer Additives business unit, that it has filed a patent infringement lawsuit in Beijing IP Court against Beijing Tiangang Auxiliary Co., Ltd. (Tiangang), following a lengthy investigation. The lawsuit, which requests injunctive relief, damages and attorneys’ fees, alleges that the making and selling of ‘Tiangang® T-68 light stabilizer’ violates the patent covering Solvay’s flagship product line, CYASORB THT® - as verified by independent laboratory analysis.

Solvay approached Tiangang several months ago to begin amicable discussions to resolve the matter, but Tiangang refused to engage in a substantive dialogue. Such refusal by Tiangang forced Solvay to rely on the Chinese Courts for protection of its patent rights. “While we welcome competition, we have zero tolerance for companies that infringe our intellectual property,” said Domenico Romanino, Senior Vice President of Polymer Additives. “Protecting patents is in everyone’s best interest as it ensures fairness and a level playing field for all market participants. Additionally, as an innovative company, Solvay will not hesitate to leverage its patents when necessary since these are the vehicles that promote invention and, ultimately, the development of new products that bring benefit to our customers around the world.”
