Solvay Sues Chinese Specialty Chemicals Maker Tiangang

Solvay has filed a lawsuit in a Beijing court against Beijing Tiangang Auxiliary Co. for infringing its patent on Cyasorb THT light stabilizer. Following a lengthy investigation, the Belgian specialty chemicals company is suing the Chinese chemicals manufacturer on behalf of its subsidiary Cytec Industries and its Polymer Additives business unit.

Solvay said in the lawsuit that the manufacture and sale of Tiangang’s T-68 light stabilizer violates the patent for its flagship Cyasorb THT product line, and it has had this verified by independent laboratory analysis. Now, Solvay is seeking injunctive relief, damages and attorneys’ fees.

According to a company spokesperson, Solvay approached Tiangang several months ago to resolve the matter amicably, but the Chinese firm refused to engage in a substantive dialogue. Consequently, Solvay has been forced to rely on the Chinese courts to protect its patent rights.

Domenico Romanino, senior vice president of Solvay’s Polymer Additives, said: “While we welcome competition, we have zero tolerance for companies that infringe our intellectual property.” According to Romanino, protecting patents is in everyone’s best interest as it ensures fairness and a level playing field for all market participants. “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,” Romanino added.

In recent years, Solvay has defended and won several patent infringement cases in China, notably relating to rare earth oxides used in automotive catalysts.
