What PTAB trial statistics measure

  • Petitions filed, split by proceeding type (inter partes review, post-grant review and, until September 16, 2020, covered business method review) and by technology area.
  • Institution decisions: how many petitions led to a trial and how many were denied.
  • Outcomes: final written decisions, settlements and other terminations.
