Huntsman Corporation has announced that the Patent Re-examination Board of the State Intellectual Property Office, China (PRB) upheld Huntsman’s Chinese Patents Nos. ZL00106403.7 and ZL200480003051.4. 

These patents were contested by Shaoxing Bangyi Chemical and Taixing Jinyun Dyestuff. By its ruling, the PRB confirmed that Huntsman’s patented technology, which is used in Huntsman’s Novacron Super Black G and Novacron Super Black R dyes, is Huntsman’s valuable innovation for producing deep black shades.

“We are very pleased with the PRB’s decision which demonstrates the State Intellectual Property Office’s commitment to steadfastly uphold intellectual property rights in China which protect valuable and advanced technology,” commented Rohit Aggarwal, President of Huntsman Textile Effects. “This encourages companies like Huntsman to continue to invest in research and development in our aim to bring cutting-edge innovation to the textile industry. Huntsman will vigorously pursue those who are infringing our intellectual property rights to stop the unlawful infringement and pursue full compensation for our losses.”

Huntsman sued Jiangsu Jinji Industrial and Taixing Jinyun Dyestuff for infringing the above mentioned Chinese Patents at the Beijing Intellectual Property Court by using Huntsman’s patented technology in six black dyestuff products. Huntsman is seeking substantial damages and an injunction against further infringement. 

Huntsman is also seeking substantial damages and an injunction against further infringement in a separate lawsuit against Zhejiang Longsheng Group, Zhejiang Keyong Chemical, and Shanghai Colva Dyestuff Industry. This matter is currently being heard before the High People's Court, Shanghai.  In earlier decisions, both the Shanghai Intermediate People’s Court and the Shanghai High People’s Court ruled that Shanghai Colva Dyestuff Industry had infringed Huntsman’s Chinese Patent No. ZL00106403.7 by manufacturing and selling Colvazol Super Black LC-G and Colvazol Super Black LC-R dyes.
