  • AIA Estoppel – 7 Things We Know So Far When the America Invents Act was enacted, one of the biggest questions facing petitioners was the scope of the estoppel set forth in 35 U.S.C. § 315(e). While IPR was expected to provide a cheaper, more efficient method of challenging the validity of a patent, what would the challenger be giving up? The statute provides that for any patent claim addressed in a final written IPR decision the petitioner (or real party in interest), may not request, maintain, or assert that... More
  • Tech Industry Debates AIA Proceedings at Inaugural PTAB Conference Introduction of Panelists and summary of Session Early March 2017 kicked off the PTAB Bar Association’s Inaugural Conference in Washington, D.C.  I had the privilege of attending several sessions, one of which was “View from the Tech Industry,” which included panelists from the Tech Industry who commonly practice before the PTAB in either petitioner or patent owner roles.

  • Federal Circuit to take AIA Time Bar issue En Banc As we had predicted in a previous post, the Federal Circuit, on January 4, 2017, granted patent owner Wi-Fi One LLC’s petitions for rehearing en banc regarding the interpretation of, and interplay between, 35 U.S.C. § 314(d) (the No Appeal provision) and § 315(b) (the Time Bar provision).  A few months ago, we wrote about the related decision Wi-Fi One, LLC v. Broadcom Corp., Appeal 2015-1944 (Fed. Cir. Sept. 16, 2016), which the court’s order vacates: In Wi­Fi, the patent owner... More

Oracle Corp., Appeal 15-1242 (Fed. Cir. Nov. 17, 2016) (non-prec.), on remand from the Supreme Court for further consideration in view of Cuozzo Speed Technologies, LLC v. Lee, 136 S.

  • PTAB Upholds Claims Under Narrowed BRI Construction on Remand The PTAB’s recent decision on remand in Corning Optical Comm. v. PPC Broadband (IPR2013-00342, Paper No. 57), and the related decision on appeal (815 F.3d 747 (Fed. Cir. 2016)), serve as a reminder that the broadest reasonable interpretation (BRI) standard does not permit an unreasonably broad construction. In addition, the PTAB’s related order (see Paper 55), denying the parties’ requests for further briefing on remand, indicates that, when the Federal Circuit bases its claim construction on a party’s construction advanced during...

  • PTAB’s Decision on Remand in Dell v. Acceleron Shows Strict treatment of Post-Petition Arguments The PTAB’s August 22, 2016, decision in IPR2013-00440 on remand from the Federal Circuit, Dell, Inc. v. Acceleron, LLC,¹ sheds light on how the PTAB may treat seemingly new or different arguments raised post-petition.  After Dell, and as discussed below, practitioners may expect the PTAB to exercise a greater degree of scrutiny when considering arguments that differ from those raised in the original petition, or that are otherwise not responsive to a patent owner’s positions raised in a response.  See 37...
