There are two primary questions: A) Did Samsung infringe on Apple's patents? and B) Are Apple's patents valid? Both A and B must be true for Apple to win the case, and the court can rule on those two issues separately. For instance, the court could rule in favor of Samsung because they found Samsung was not infringing on Apple's patents, but leave the patents intact if B is satisfied. They could also rule in Samsung's favor because Apple's patents were invalid.
