$45 million judgment overturned for Ericsson

Finnegan convinced the Federal Circuit to wipe out a $45 million judgment against Ericsson. Harris Corporation had sued Ericsson in the Northern District of Texas on a patent related to technology for correcting intersymbol interference, which can arise during use of communications equipment such as cell phones. The Federal Circuit agreed that the district court misconstrued the claims, and erred in its calculation of the appropriate royalty rate. The Federal Circuit also ruled against Harris on its cross-appeal, which concerned the award of enhanced damages.
