Samsung has been ordered to pay $1billion in damages to Apple after a US court ruled that it copied Apple's designs for the iPhone.
After three days of deliberation, the nine-person jury said Samsung was "wilful in its infringement" of Apple's intellectual property, and found overwhelmingly in its favour..
Apple had sought a total of $2.5billion in damages, claiming that both the iPad and the iPhone were copied by Samsung in its Galaxy S and Galaxy Tab products.
The jury dismissed the claim that Samsung had copied the iPad, but upheld several relating to the look and feel of the iPhone.
Patents and designs found to have been copied included the 'bounce-back' feature on Apple's devices, which let a user know when they've reached the end of a screen, and the tap-to-zoom feature.
The jury said that Samsung executives either knew, or should have known that they were in violation of the patents.
In total it awarded Apple $1.049 in damages, and published a complete list of the amount awarded for each device.
The jurors also rejected Samsung's counter claim for $519m in damages not he grounds that Apple violated several patents of its own.
A hearing will now be held on 20 September at which Apple will file for an injunction against the sale of the Samsung products found to be in violation of its patents.
Samsung said that the verdict was a "loss for the American consumer" and said it will immediately move to try and overturn the decision.
"It will lead to fewer choices, less innovation, and potentially higher prices. It is unfortunate that patent law can be manipulated to give one company a monopoly over rectangles with rounded corners, or technology that is being improved every day by Samsung and other companies.
"Consumers have the right to choices, and they know what they are buying when they purchase Samsung products. This is not the final word in this case or in battles being waged in courts and tribunals around the world, some of which have already rejected many of Apple's claims. Samsung will continue to innovate and offer choices for the consumer."
Apple said it was "grateful" to the jury, adding that "stealing isn't right".
"We are grateful to the jury for their service and for investing the time to listen to our story and we were thrilled to be able to finally tell it.
"The mountain of evidence presented during the trail showed that Samsung’s copying went far deeper than even we knew. The lawsuits between Apple and Samsung were about much more than patents or money. They were about values. At Apple, we value originality and innovation and pour our lives into making the best products on earth.
"We make these products to delight our customers, not for our competitors to flagrantly copy. We applaud the court for finding Samsung’s behavior willful and for sending a loud and clear message that stealing isn’t right."
Apple CEO Tim Cook added later in a memo to employees that "today, values have won and I hope the whole world listens".
