By Simona Stankovska, staff reporterBaton Rouge, Louisiana -- US speciality chemicals firm Albemarle Corp. has filed a patent infringement action against Isochem Kautschuk GmbH for allegedly copying its German patent, which is used to produce its Saytex 8010 flame retardant.The action was filed in Düsseldorf's district court, and states that Isochem has infringed Richmond, Virginia-based Albemarle's intellectual property by importing and selling flame-retardants in Germany, which were produced using the company's German patent, DE 69105046 (European patent number 0 460 922)."German law clearly states that it is 'illegal to import into, to offer for sale or to use within Germany products that are produced by a process that is protected by a German patent'," said Albemarle, in a 15 Aug statement."The company views its dedication to innovation as one of its core assets and will rigorously protect the creative and intellectual property of its employees against any encroachment attempts, intentional or accidental," said Albemarle's lawyer Dr Thorsten Vormann, in the statement. "We are confident that the German courts will uphold the validity and enforceability of this patent and look forward to presenting our case in the near future," he added.Isochem however, believes that Albemarle's claims are unjustified. "Contrary to these claims, this supplier does not employ this patented process for DPE, so the problem should be a non-issue as far as we can tell," said a spokesperson for Isochem, in a 16 Aug email to Urethanes Technology International. The spokesman added that Isochem does not have any active customers for DPE, and posed questions on Albemarle's claims. He also said that Albemarle made no attempt to contact Isochem about the issue and give them any warning before filing the dispute. "There are many things about this case that could have saved both sides a lot of trouble and money if any kind of dialogue had taken place beforehand," said the spokesman."
