District Court Should Have Corrected Evident Error in Claim Language: Federal Circuit

In Canatex Completion Solutions, Inc. v. Wellmatics, LLC, the US Court of Appeals for the Federal Circuit reversed the district court's invalidity for indefiniteness determination based on erroneous claim language that the patent owner argued was an evident error. The Federal Circuit concluded that the error in the claim language was evident on the face of the patent and that the proposed correction was the only reasonable correction based on the intrinsic evidence.
