Huntsman Corporation has announced that the Patent Re-examination Board of the State Intellectual Property Office, China (PRB) upheld Huntsmanâ€™s Chinese Patents Nos. ZL00106403.7 and ZL200480003051.4. These patents were contested by Shaoxing Bangyi Chemical Co Ltd and Taixing Jinyun Dyestuff Co Ltd. By its ruling, the PRB rejected the positions of the petitioners and confirmed that Huntsmanâ€™s patented technology, which is used in Huntsmanâ€™s NOVACRONÂ® Super Black G and NOVACRONÂ® Super Black R dyes, is Huntsmanâ€™s valuable innovation for producing deep black shades.
Huntsman sued Jiangsu Jinji Industrial Co Ltd and Taixing Jinyun Dyestuff Co Ltd for infringing the above mentioned Chinese Patents at the Beijing Intellectual Property Court by using Huntsmanâ€™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 Co Ltd, Zhejiang Keyong Chemical Co Ltd and Shanghai Colva Dyestuff Industry Co Ltd. This matter is currently being heard before the High Peopleâ€™s Court, Shanghai. In earlier decisions, both the Shanghai Intermediate Peopleâ€™s Court and the Shanghai High Peopleâ€™s Court ruled that Shanghai Colva Dyestuff Industry Co Ltd had infringed Huntsmanâ€™s Chinese Patent No. ZL00106403.7 by manufacturing and selling Colvazol Super Black LC-G and Colvazol Super Black LC-R dyes.
Rohit Aggarwal, President of Huntsman Textile Effects said: â€œWe are very pleased with the PRBâ€™s decision which demonstrates the State Intellectual Property Officeâ€™s commitment to steadfastly uphold intellectual property rights in China which protect valuable and advanced technology. 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 lossesâ€
