Rohm & Haas Electronic Materials CMP Holdings Inc. filed a civil action in the Intellectual Property Court against NexPlanar Corporation alleging that NexPlanar Corporation’s polishing pads infringed on Rohm & Haas’s two Taiwan patents.  In December 2014, the Supreme Court affirmed the decision rendered by the second instance of the Intellectual Property Court dismissing the appeal filed by Rohm & Haas against NexPlanar Corporation, on the grounds that the asserted claims of the plaintiff’s two Taiwan patents are invalid due to lack of inventive step.
