$506M Judgment Against Apple in WARF Lawsuit Is Reversed on Appeal

September 28, 2018

The Federal Circuit has overturned an infringement verdict against Apple in litigation brought by the Wisconsin Alumni Research Foundation (WARF), the non-profit, patent management arm of the University of Wisconsin. In that case, a Wisconsin jury found in October 2015 that Apple had infringed a single WARF semiconductor patent through its A7 and A8 processors, with the court issuing a $506M final judgment following the trial (3:14-cv-00062). However, the Federal Circuit ruled in a September 28 opinion that the infringement verdict is not properly supported by the evidence based on the plain and ordinary meaning of a key claim limitation (2017-2265, 2017-2380).
