Last June, the Federal Circuit overturned a $2.7B judgment for Centripetal Networks in its litigation against Cisco, ruling that Eastern District of Virginia District Judge Henry C. Morgan, Jr. should have recused himself due to conflicts involving his wife’s ownership of stock in the defendant. That case, now back before a new district judge due to Judge Morgan’s death, has just hit another potentially fatal setback. On December 11, District Judge Elizabeth W. Hanes also reversed Judge Morgan’s judgment of infringement, holding that Centripetal had failed to establish that Cisco’s accused networking and cybersecurity products meet a set of key claim limitations.
