No Second Bite Of The Apple for Square, Inc. - PTAB Applies Estoppel Provision Of 35 U.S.C. §325(e)(1) TO CBM Review

In the case of Square, Inc. v. Unwired Planet, LLC (CMB2015-00148), the PTAB held that the grounds raised by Square, Inc. (Petitioner) to challenge the validity of claims 1-4 of Unwired Planet’s U.S. Patent No. 7,711,100 could have been raised in a previous petition filed by Square, Inc. against the same patent, and hence denied the institution of a covered business method (CBM) review. In particular, the Board relied on the estoppel provision of 35 USC 325(e)(1), to deny the institution of a CBM review. This portion of section 325 mandates that the petitioner, or the real party in interest or privy of the petitioner, in a post-grant review of a claim that results in a final written decision “may not request or maintain a proceeding before the Office with respect to that claim on any ground that the petitioner raised or reasonably could have raised during that post-grant review.”
