U.S. District Court Judge William Conley just ordered Apple to pay $506 million to the Wisconsin Alumni Research Foundation for patent infringement. Around half of the money, $234 million of it is actually owed by Apple from a different verdict back in 2015.

Wisconsin Alumni Research Foundation or in short, WARF, is responsible for creating the computer processing chips used in iPhones, chip that significantly improves the efficiency and speed of computer processing. And according to the verdict Apple never legally had the right to use those chips.

While the patent expired in the end of 2016, Apple owes WARF for the usage of the chips prior to that time.

"WARF will continue to defend the work of the university researchers and WARF's patent in this case should Apple, Inc. file an appeal. WARF does not typically comment on litigation and will not plan to comment further on details associated with this case until the matter is fully reviewed and resolved in court." -- Yasiri Moe, WARF.

Apple is expected to appeal the ruling.
