The U.S. Court of Appeals for the Federal Circuit in Washington, D.C., said Samsung Electronics Co Ltd did not infringe Apple's "quick links" patent, and that two other patents covering the iPhone's slide-to-unlock and auto-correct features were invalid. The court also said Apple was liable for infringing one of Samsung's patents.
The ruling was issued by a unanimous three-judge panel. Both Apple and Samsung declined to comment on the decision.
Samsung is also appealing a separate case to the U.S. Supreme Court in which it paid Apple $548.2 million for violating its patents.
