In the time since the America Invents Act (AIA) created the Patent Trial and Appeal Board (PTAB), inter partes review (IPR) and other PTAB proceedings for challenging patents' validity have proven to be powerful tools for those accused of infringement. But increasingly, the PTAB's exercise of its discretion to deny institution of review for non-merits-based reasons has become a powerful counter-defense for patent owners. Although discretionary denial has been a feature of PTAB proceedings since their inception, the range of circumstances in which the PTAB discretionarily denies institution and the frequency with which it does so are increasing. Discretionary denial has thus become a disputed issue in an increasingly large proportion of PTAB proceedings.
