Federal Court Invalidates Patent Troll Case Against EFI and Others

Foster City, California-based EFI, a world leader in customer-focused digital printing innovation, announced that a federal court has dismissed a patent infringement lawsuit brought by Digitech Image Technologies LLC ostensibly related to digital image processing technology.

Digitech, a subsidiary of the non-practicing entity Acacia Research Corporation, had filed suit in the United States District Court for the Central District of California against EFI and dozens of others, including EFI customers and retailers like Overstock.com and Buy.com, alleging infringement of US Patent No. 6,128,415. EFI requested that the court strike the infringement allegations against EFI's products and invalidate the asserted patent.
