Samsung has lost two more motions in its attempt to undo a preliminary injunction of US Galaxy Tab 10.1 sales. FOSS Patents reports that the Court of Appeals for the Federal Circuit has blocked one motion to stay the injunction for the duration of the appeal proceedings, and another hoping to expedite the process. In effect, the motions mean that Samsung won't have another chance to overturn the injunction until sometime after July 30th, when Apple and Samsung are set to go to trial.
