WARF, the patent licensing arm of UW-Madison, sued Apple in 2014 for infringing on a patent for technology used in iPhones and iPads.
The industry giant failed to adhere to the initial 2015 ruling, in which $234 million was the fine ordered by the judge. Interestingly, this comes in the back of another order that required Apple to pay $234 million to WARF on the same charges. Quite a lot, according to US District Judge William Conley in Madison, Wisconsin, who found the world's most profitable smartphone manufacturer guilty of violating a computer processor patent granted to a University of Wisconsin professor and three students way back in 1998. While Apple is pretty loaded in terms of cash, $506 million is definitely no small figure to be sneezed at. Apple plans to appeal the ruling reports MacRumors. Whether or not they will be successful remains to be seen, or whether or not they might end up settling with the university for a different amount. An Apple spokesman did not immediately return a request for comment.
Apple, during the trial before a jury, reportedly argued that the patent was not valid and called for a Trademark Office review of the patent's validity. This enables a processor to predict what instructions a user will put into the system based on previous choices.
The original case covered Apple's use of the invention in its A7, A8 and A8X processors, which are found in devices including the iPhone 5S and the iPad Air 2.
Conley did rule in favor of Apple on WARF's claims of willful infringement. Conley said he would only announce a ruling in that case after Apple has had an opportunity to appeal the 2015 jury verdict.
