WASHINGTON -(Dow Jones)- In a mixed ruling, a federal appeals court on Monday revived Apple Inc.'s (AAPL) bid to block U.S. sales of Samsung Electronics Co.'s (005930.SE, SSNHY) Galaxy Tab tablet computer, but rejected other Apple legal claims that sought to bar sales of Samsung smartphones.

Apple argues Samsung's products copy its patented designs for the iPhone and iPad. The companies are locked in several patent disputes around the globe.

The U.S. Court of Appeals for the Federal Circuit ruled a California trial judge was too quick to deny Apple's request to temporarily block the sales of Samsung tablets while Apple's patent-infringement claims against its rival proceed in court.

A three-judge appeals-court panel ruled the California judge was incorrect in thinking that one Apple patent related to the iPad may be invalid. The court said the Cupertino, Calif., company would suffer "irreparable harm" from the sales of Samsung's allegedly infringing tablets, and it ordered the trial judge to consider again Apple's arguments that sales of the Samsung tablets should be blocked while the legal case proceeds.
