We represented American Express Co. in a patent infringement action targeting its gift card products, in which plaintiff PrivaCash sought over $100 million in past damages and future royalties.  The firm obtained a dismissal of codefendant American Express Incentive Services, LLC ("AEIS") early in the case after proving that AEIS's gift cards were distributed and sold in the business-to-business environment and therefore could not infringe plaintiff's patent.  We then sought and secured a favorable claim construction ruling for remaining defendant American Express, and shortly thereafter filed a motion for summary judgment of non-infringement.  Approximately one month before trial, the Court granted American Express's motion and entered summary judgment of non-infringement in favor of American Express.  On August 11, 2011, after full briefing and oral argument, the Federal Circuit affirmed the District Court's summary judgment of non-infringement in favor of American Express.
