A U.S. federal court jury on Friday said it has found Samsung infringed six of Apple's patents and ordered it to pay more than 1 billion U.S. dollars in damages to Apple.

The verdict was read in a U.S. district court in San Jose, in northern California, after three days of jury deliberation.

The nine-member jury found that Samsung products violated Apple 's patents related to screen bounceback and zooming, saying that the Korean company also infringed the design and graphical interface of Apple's iPhone.

But the jury found that Samsung did not infringe Apple's design patent of the iPad tablet computer, according to U.S. media reports.

The jury also ruled that Apple didn't infringe any Samsung patents.

The verdict is seen as a big win for Apple in a closed-watched patent lawsuit billed by some U.S media as "the patent trial of the century."

The jury trial started on July 30 after Apple claimed that Samsung copied its iPhone and iPad, seeking more than 2.5 billion dollars in damages. Samsung denied the charge, and made counterclaims that Apple violated its own patents.
