Samsung Electronics won a round over Apple in their ongoing patent litigation when a Dutch court cleared Samsung's Galaxy tablets from infringing on Apple's design rights in a ruling that covers the entire European Union, not just the Netherlands. But Apple can still pursue a patent suit against Samsung, a court spokeswoman said. In other patent news, the companies added a number of gadgets to their ongoing lawsuit in a California federal court, where a trial is scheduled to begin in March 2014.
