Supreme People’s Court rejects Colva’s Request for Retrial

Singapore, 15 February 2017 - The Textile Effects division of Huntsman Corporation (NYSE: HUN) today announced that the Supreme People’s Court of the PRC rejected Shanghai Colva Dyestuff Industry Co., Ltd. (“Colva”)’s  request for a retrial of the patent infringement claim brought by Huntsman. 

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. (Stock Exchange No. 600352, Ticker Symbol ”Zhejiang Longsheng”), Zhejiang Keyong Chemical Co., Ltd., and Colva.

Rohit Aggarwal, President of Huntsman Textile Effects said: “We are extremely pleased with the Supreme People’s Court’s decision to protect and uphold valuable intellectual property rights of companies.  This will spur Huntsman’s ongoing investments in cutting-edge technology to bring new and exciting innovation to our customers and the industry.”

“This favorable and conclusive judicial decision of the Supreme People’s Court sends a strong signal and demonstrates its commitment in safeguarding intellectual property rights of both local and multinational companies in China, ” Mr Aggarwal continues.

Huntsman’s patented technology is a true innovation for producing deep black shades.  It is used in Huntsman’s NOVACRON® Super Black G and NOVACRON® Super Black R dyes. Making, using, importing or selling non-Huntsman products that use Huntsman’s patented chemistry is an infringing act.
