Los Angeles-based online e-commerce retailer Newegg is trumpeting a new patent victory, saying that a "notorious troll" has been ordered to pay the company's cost in a patent ruling. Newegg said that the Federal Circuit Court of Appeals invalidated U.S. Patent No. 6,128,415, a patent which covered the idea of tagging information about an image. NewEgg said that Digitech Image Technologies LLC--a subsidiary of Acacia Research--had sued Xerox, Toshiba, Fujifilm, Ricoh, Overstock.com, and Newegg for patent infringement over the patent, which had previously been owned by Polaroid. Newegg also took issue with Acacia's press releases and patent strategy. Acacia Research is based in Newport Beach, and acquires patents and aggressively licenses them to companies; the company is no stranger to patent infringement lawsuits and countersuits.
