The court ordered Samsung Electronics to pay Apple damages, determined by how much profit it has made from the sales.
The patent dispute concerns the Android operating system versions 2.2.1 to 3.0 used on Samsung's Galaxy tablets and smartphones, the court said.
Samsung and Apple, the world's top two smartphone makers, are locked in patent disputes in at least ten countries as they vie to dominate the lucrative mobile market and win over customers with their latest gadgets.
Samsung, the world's top maker of smartphones, infringed Apple patents to make its smartphones and tablets, a U.S. trade panel judge said in a preliminary decision issued last month.
Samsung won a court case last month in the Netherlands, when a Dutch court ruled the company did not infringe an Apple patent by using certain multi-touch techniques on some of the Samsung Galaxy smartphones and tablet computers.
