A judge in the United States ruled that Apple must pay Wisconsin-Madison University US$506million for violating its permit.

Apple is appealing the new rule in the federal circuit, as according to The Verge, the amount is double what the jury originally decided on.

The increased amount of US$506million is punishment for Apple’s continual infringement from October 2015, as a jury ruled that Apple committed patent infringement when creating mobile chips used in its iPhone, iPad Mini and iPad Air.

The A7, A8 and A8X processers used in the iPhone 5S, 6 and 6 Plus were found to have profited from the university’s patented technology, causing Apple to pay US$234million in damages – although the company claims it is innocent.

The judges set the maximum damages for the trial to be US$862million, but the damages were then limited as Apple’s infringement was found to be without intent.
