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

    Market Sector: Semiconductors

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).
