Apple has asked a US court to increase the damages Samsung must pay over design patent infringements by over half a billion dollars.
Samsung lost the case against Apple in late August, and was ordered to pay $1bn in damages as a result, in what was the biggest profile ruling in the numerous legal battles between the two smartphone giants to date.
However, according to widespread reports Apple has now returned to the US District Court in San Jose, California asking for a further $707m in damages.
"The harm to Apple was deliberate, not accidental," Apple attorneys said in court papers filed on Friday.
"[Samsung] wilfully diluted its trade dress, taking billions in sales in the fast-growing US smartphone market at a key moment in the transition between feature phones and smartphones."
V3 contacted Apple and Samsung for comment but had received no reply at time of publication.
The move comes as Apple launches its latest iPhone 5 device to huge crowds in stores across the world including London, as it seeks to cement its dominance in the market, with two million preorder sales reported.
Despite the success of the device, though, Apple has come under fire for the new Maps tool in its iOS 6 operating system, with users complaining towns and cities are located incorrectly, or missing altogether while the overall detail of the maps is inferior to Google's service, which it replaced.
