In re: Affinity Labs of Texas, LLC

Pre-AIA section 317(b) precluded argument that Patent and Trademark Office (PTO) was prohibited from maintaining reexamination of multiple claims where court upheld only two claims in parallel litigation. King requested ex parte reexamination of all claims of Affinity’s patent. Volkswagen requested inter partes reexamination based on additional, different asserted grounds of unpatentability; Apple requested inter partes reexamination of based on still different grounds. The PTO granted and merged the requests. Volkswagen subsequently received an adverse final judgment in a parallel district court proceeding, upholding the validity of claims 28 and 35. Affinity petitioned the PTO to vacate the entire merged reexamination proceeding, arguing that the estoppel provision in pre-America Invents Act (AIA) 35 U.S.C. 317(b) extended to all parties and all claims, not just litigated claims 28 and 35. The PTO denied Affinity’s request, but severed the Volkswagen reexamination and held that no rejection could be maintained in that reexamination as to claims 28 and 35. The Examiner evaluated the Volkswagen reexamination separately and issued a Right of Appeal Notice in each proceeding, rejecting numerous claims as unpatentable. The Patent Trial and Appeal Board and Federal Circuit affirmed, rejecting Affinity’s arguments that the PTO erred in maintaining the reexaminations, given the final decision that Volkswagen failed to prove invalidity of two claims, and that, assuming the reexaminations were properly maintained, the decisions were based on misreadings of asserted prior art and misevaluation of Affinity’s objective indicia evidence of nonobviousness.
