A U.S. appeals court on Friday affirmed a decision to throw out a $308.5 million jury verdict against Apple Inc. for allegedly infringing a patent related to digital rights management.
The U.S. Court of Appeals for the Federal Circuit in Washington, D.C., upheld an East Texas federal judge’s ruling that Personalized Media Communications LLC’s patent was invalid because the company engaged in misconduct before the U.S. Patent and Trademark Office.
