Oblon, Spivak Wins Second Jury Trial in Six Weeks; Jury Finds Patent Infringement
For Immediate Release
September 22, 2005
Alexandria, Va. – A jury in U.S. District Court for the District of South Carolina in Greenville has awarded $90,000 in damages to DyStar Textilfarben GmbH & Co. Deutschland KG, a German dyestuff and chemical manufacturer due to patent infringement by C.H. Patrick Co., Inc. and Bann Quimica LTDA. DyStar is a client of Oblon, Spivak, McClelland, Maier & Neustadt, P.C. This is the second jury trial won by the Oblon, Spivak firm this year.
After a six-day trial, the Federal District Court Judge granted judgment on September 7, 2005 to DyStar on the issue of unenforceability and instructed the jury to determine validity, infringement and the amount of damages, if any, due DyStar. On September 16, the jury returned a verdict in favor of DyStar and awarded damages.
The suit involved a patent (U.S. 5,586,992) owned by DyStar connected with its innovative Indigo Vat Solution, which has become the industry benchmark and process of choice for most international denim producers. The benefits relate to a process for dyeing textile materials using an aqueous solution of leuco indigo prepared by catalytic hydrogenation. The use of this process provides dyehouses with economic and ecological advantages, increasing the producer's profits and minimizing environmental pollution. Bann and Patrick completed one sale of about 50,000 pounds of solution to a dyehouse in the US for use by that dyehouse in the claimed process, prior to being sued.
“DyStar is gratified that the Judge found Bann and Patrick’s inequitable conduct defense to lack merit and pleased that the jury found its patent not invalid and infringed and awarded damages caused to DyStar by Bann and Patrick’s infringement,” said William T. Enos, a partner at Oblon, Spivak, McClelland, Maier & Neustadt, P.C., and the lead counsel for the Plaintiff. Oblon, Spivak has been and continues to be represented in this case by William Enos, Richard Kelly and Andrew Beverina. The Firm was assisted by Ron Tryon of Parker, Poe, Adams & Bernstein LLP, of Columbia, South Carolina during the trial.
The head of DyStar’s Patent Department, Dr. Ralf Muley, who worked closely with the firms, stated “Our attorneys did a terrific job throughout the case. We are very pleased with their performance and preparation for the trial. Mr. Enos and his team have worked hard for more than three years on this case and their efforts have allowed us to obtain the decisions and verdict we now have in this case. DyStar is committed to the protection of its intellectual property rights.”
This jury verdict and award culminates proceedings that began with the filing of the complaint in September 2002.
