Tempe, Ariz. (August 22, 2008) DuPont Air Products NanoMaterials L.L.C. (DA NanoMaterials) remains confident in its legal positions following a Markman ruling as part of the patent invalidity/non-infringement lawsuit with Cabot Microelectronics Corporation, currently under way in the U.S. District Court for the District of Arizona.
The Markman ruling by the Court is an interim pre-trial ruling that did not decide the ultimate issues of the case. Notably, the Markman ruling clarifies what each side will need to prove to establish their respective allegations on invalidity and non-infringement of Cabot’s patents at trial. DA NanoMaterials is prepared to proceed to a full trial on the merits against Cabot.
DA NanoMaterials remains committed to its innovative and patented products and looks forward to its opportunity to defend these products in its lawsuit against Cabot and to continue to compete in the marketplace with its superior technology and customer service.
