In re: Affinity Labs of Texas, LLC

by
Estoppel provision of section 317(b) did not prohibit the Patent and Trademark Office (PTO) from maintaining a reexamination after court's dismissal, without prejudice, of invalidity claims..Apple requested reexamination after Affinity filed suit, alleging infringement of Affinity’s patent. While the reexamination was pending, the parties settled and filed a stipulation of dismissal with the district court. Affinity’s infringement action was dismissed with prejudice and Apple’s invalidity counterclaims were dismissed without prejudice. Apple filed notice of non-participation in the reexamination. Affinity petitioned the PTO to terminate the reexamination in view of the dismissal of Apple’s district court counterclaims pursuant to pre-America Invents Act (AIA) 35 U.S.C. 317(b), which prohibited the PTO from maintaining an inter partes reexamination after the party who requested the reexamination has received a final decision against it in a civil action concluding “that the party has not sustained its burden of proving the invalidity of any patent claim in suit.” The PTO dismissed Affinity’s request because it did not view the dismissal, without prejudice, as meeting section 317(b)’s required condition. The Examiner rejected all of the patent’s claims. The Patent Trial and Appeal Board and the Federal Circuit upheld the rejection, rejecting Affinity’s claims that the PTO improperly maintained the reexamination and that the Board’s finding that all claims are unpatentable was based on improper claim construction.
