Apple adds Samsung’s Galaxy S4 to lawsuit

Apple continues to target competitor Samsung with patent-related lawsuits. It has filed a new motion in California that claims the Galaxy S4, Samsung’s flagship smartphone, violates five of its patents.

Two of those patents pertain to voice search. The motion is an amendment to an existing patent claim.

Apple and Samsung are locked in bitter legal battles around the globe, and two of the cases are playing out in California courts. The first reached a major decision last August when a jury found Samsung guilty of infringing on several Apple patents. It ordered Samsung to pay US$ 1.05 billion in damages. The U.S. District Court Judge Lucy Koh, who is overseeing that case, later reduced the damages award by US$ 400 million, saying that the jury didn’t calculate the damages correctly. Samsung still owes Apple more than US$ 600 million, but Apple likely won’t see a penny until the two companies’ present final arguments on the damages in a hearing scheduled for November.

The new motion pertains to the second case, which is still in the early stages.
