The Supreme People’s Court in China has rejected Shanghai Colva Dyestuff Industry Co., Ltd.’s request for a retrial of the patent infringement claim brought by Huntsman Textile Effects.

In earlier decisions, both the Shanghai Intermediate People’s Court and the Shanghai High People’s Court ruled that Colva had infringed Huntsman’s Chinese Patent No. ZL00106403.7 by manufacturing and selling Colvazol Super Black LC-G and Colvazol Super Black LC-R. With the Supreme People’s Court’s decision above, Huntsman has finally prevailed over Colva in this patent infringement action.

In a separate action that is currently pending before the High People’s Court, Shanghai, Huntsman is seeking substantial damages of RMB 231 million and an injunction against further infringement from Zhejiang Longsheng Group Co., Ltd.; Zhejiang Keyong Chemical Co., Ltd.; and Colva.
