Huntsman Sues Zhejiang Longsheng Group for RMB 231 Million for Patent Infringement Damages

Singapore -- The Textile Effects division of Huntsman Corporation (NYSE: HUN) announced it has sued Zhejiang Longsheng Group Co., Ltd. (“Longsheng”) and its subsidiaries Zhejiang Keyong Chemical Co., Ltd. (“Keyong”) and Shanghai Colva Dyestuff Co., Ltd. (“Colva”) for infringing its Chinese Patent No. ZL00106403.7 by making and selling certain black dyes.  Huntsman is seeking substantial damages of RMB 231 million and an injunction against further infringement.

Huntsman’s lawsuit follows the decision of the Shanghai High Court affirming the judgment of the Shanghai First Intermediate People’s Court rendered in May 2013, which found 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.  Colva was ordered by the court to immediately stop manufacturing and selling the infringing products and to pay statutory damages to Huntsman. 

Longsheng controls both Keyong and Colva, and all three companies manufacture and sell textile dyes in China.  Longsheng also has majority ownership of the Dystar Group.
Paul Hulme, President of Huntsman Textile Effects said: “Huntsman is fully committed to protecting its intellectual property rights, and will vigorously pursue those who are making and selling infringing products and to obtain full compensation for our damages”.

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. The making, use, importation or sale of products, which use Huntsman’s patented technology without authorization, is an infringing act. Huntsman would be pleased to support its customers and textile value chain partners with any questions that they may have relating to this issue.
