Apple won a partial victory in its long-running patent dispute with Samsung on Friday when a federal administrative panel found Samsung in violation of two Apple patents and blocked imports of some Samsung devices.
Even as the US International Trade Commission (ITC) found Samsung in violation of the two patents, it cleared the South Korean company on four other patents in dispute.
Samsung Electronics Co and Apple Inc are in a global legal battle over smartphones. Apple argues Samsung's Android phones copy vital iPhone features. Samsung is fighting back with its own complaints.
Samsung has been cutting into Apple's dominance in phones and is now the leading smartphone manufacturer. It is also pushing into Apple's territory with its own Android tablet computers.
The legal disputes come as competition in the marketplace intensifies. These cases typically involve older products that are no longer widely sold.
Two of the phones cited in Friday's ruling were both 2010 models - the Continuum and the Transform.
Nonetheless, a victory in such cases could affect what features are included in future devices and could slow down a rival's momentum.
Samsung spokesman Adam Yates said the company was disappointed in the ban, but said the ruling did reject Apple's effort "to use its overbroad design patents to achieve a monopoly on rectangles and rounded corners". Yates said Samsung will continue to release new products and have taken measures to ensure they will continue to be available in the US.
In a statement, Apple said the ITC "has joined courts around the world in Japan, Korea, Germany, Netherlands and California by standing up for innovation and rejecting Samsung's blatant copying of Apple's products. Protecting real innovation is what the patent system should be about."
President Barack Obama's administration has 60 days to veto ITC rulings.
Over the weekend, the administration invalidated a June order that sided with Samsung and banned imports of Apple's iPhone 4 and a variant of its iPad 2.
But the patents involved in Friday's ruling aren't of the type that Obama found objectionable.
