Sometimes you have to know when to quit. Nobody like a sore loser, so maybe that what happened to Apple.
The Cupertino based company was sued in 2014 by the University of Wisconsin for infringing its patent registered way back in 1998, which helped improve chip efficiency, on the A7, A8 and A8X processors.
In October 2015, the judge that was appointed to the case, found Apple guilty, but denied the total amount that the Wisconsin Alumni Research Foundation (WARF) of the University of Wisconsin asked for. Instead of accepting the $862 million demanded by WARF, the judge decided that Apple would pay only $234 million since it infringed the patents unwillingly.
Apple wasn’t satisfied with the verdict and refused to pay the damages and requested U.S. Patent and Trademark Office to review the patent’s validity but the agency rejected that bid.
In all this time Apple continued to use the patents, so the damages needed to be recalculated. So, the new judge that took over the case, decided to add $272 million to the initial penalty for additional damages plus interests, because Apple continued to infringe de patents.
So, if Apple would’ve settled with the first verdict, now they wouldn’t have to pay $506 million dollars in damages to WARF.
