Patent lawsuit against EFI dismissed

August 13, 2013

On August 6, a federal court invalidated the patent in question and ruled in favor of EFI and 34 other defendants.

EFI, a provider of customer-focused digital printing products, 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 and, 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.

On August 6, the court invalidated the patent and entered judgment against Digitech and in favor of EFI and the other remaining 34 defendants.

"Rejecting Digitech’s efforts to save its patent, the court recognized that even Digitech’s most 'creative arguments' could not 'salvage an unpatentable principle and transform it into a patentable process," the company says. "The court concluded that asserted claims are 'intangible, possess no meaningful non-abstract limitations, and are therefore ineligible for patent protection.”

According to the company, Digitech reached settlements with a number of parties, but EFI refused to settle and insisted that it was "never a proper party to the case in the first place."

“We are pleased that the court invalidated the patent, but it was clear this case should never have been filed,” says EFI General Counsel Bryan Ko. “It is yet another illustration of how patent trolls are clogging the judicial system and wasting public resources. Until the system changes, however, EFI won’t be bullied into settling these abusive lawsuits.”
