Federal Circuit Overturns PTAB Decisions That Left Network-1 Patents Largely Intact in Google IPRs

The Federal Circuit has reversed a series of final decisions that mostly upheld the validity of four patents held by Network-1 Technologies, Inc. in four inter partes reviews (IPRs) filed by Google. In a March 26 opinion, the appeals court held that the Patent Trial and Appeal Board (PTAB) erred in its construction of a key claim term upon which those June 2016 decisions had turned, remanding for further proceedings consistent with Google’s preferred construction.
