Apple and Samsung make the bestselling smartphones in the market
The jury in the Apple-Samsung lawsuit has reached a verdict.
Details of its decision will be announced shortly, but the speed with which it came to a judgement has surprised many observers.
The iPhone maker had claimed a total of $2.5bn (£1.6bn) in damages for what it said were seven patent breaches in addition to other trade violations.
Samsung had denied the charges and in turn called for $519m for five patents that it claimed Apple had infringed.
The nine-person jury at the federal court in San Jose, California had to consider 700 questions about each sides' claim that its rival had infringed its intellectual property.
Samsung's lawyers requested time to read over the verdict before it was presented to the court which Apple agreed to. Judge Lucy Koh has allowed quarter of an hour for both sides to prepare.
There has been a spate of lawsuits involving mobile-device makers, but this is viewed as one of the most significant to date because of the size of the potential damages involved, the likelihood it will influence the way future patent licenses are handled, and the insights it has given into both Apple and Samsung's working practices.
The two companies remain involved in other lawsuits in the US, UK, South Korea Germany and Australia.
