Paul Andre and Centripetal Networks Inc. got some payback last week at the Patent Trial and Appeal Board.

Last year Andre and his Silicon Valley colleagues at Kramer Levin Naftalis & Frankel saw a $2.75 billion patent infringement judgment they’d won against Cisco Systems Inc. wiped out at the U.S. Court of Appeals for the Federal Circuit. U.S. District Judge Henry Morgan was disqualified because his wife held $4,687.99 worth of stock in Cisco. The case has been assigned to U.S. District Judge Elizabeth Hanes for a retrial.
