The Federal Circuit's En Banc Consideration of Claim Construction in Phillips v. AWH Corp.
Federal Circuit decisions on how to interpret patent claim language are critically important. Unfortunately, however, recent Federal Circuit decisions do not reflect a unitary approach to patent claim interpretation.
