We previously reported how the PTAB’s institution rate has fallen to approximately 40% in the new administration, with many of those denials stemming from the PTAB’s increased usage of its discretionary denial processes to deny IPR challenges without otherwise addressing the merits of the identified prior art. The latest grant of discretionary denial continues that trend and exemplifies the current challenges in pursuing IPR/PGR invalidity challenges at the U.S. Patent Office.

What Is an Inter Partes Review (IPR)?
An inter partes review of a patent is a type of administrative trial proceeding. Inter partes review became available in 2012 and replaced inter partes reexamination as a way to challenge patentability at the Patent Office. Any person who is not the owner of a patent can file a petition for a review of a patent. The Patent Trial and Appeal Board (PTAB) will act on the petition either instituting a trial or denying institution of a trial. This will occur a little over six months after the petition is filed. If trial is instituted, the proceeding will, with some limited exceptions, be resolved within one year.

What Is the Patent Trial and Appeal Board?
The Patent Trial and Appeal Board (PTAB) is a tribunal within U.S. Patent and Trademark Office. The PTAB oversees trial proceedings, namely: inter partes review (IPR), post-grant review (PGR), covered business method (CBM) review, and derivation proceedings. The Board also hears appeals from adverse patentability decisions by patent examiners in original applications, reissues, and reexaminations. And, while phasing out since the passage of the America Invents Act (AIA) in 2011, the PTAB is also responsible for deciding interferences. The PTAB was previously referred to as the Board of Patent Appeals and Interferences and was renamed by the AIA.
