The United States Patent and Trademark Office (USPTO or Office) revises the rules of practice for instituting review on all challenged claims or none in inter partes review (IPR), post-grant review (PGR), and the transitional program for covered business method patents (CBM) proceedings before the Patent Trial and Appeal Board (PTAB or Board) in accordance with the U.S. Supreme Court decision in SAS Institute Inc. v. Iancu (SAS). Consistent with SAS, the Office also revises the rules of practice for instituting a review, if at all, on all grounds of unpatentability for the challenged claims that are asserted in a petition. Additionally, the Office revises the rules to conform to the current standard practice of providing sur-replies to principal briefs and providing that a reply and a patent owner response may respond to a decision on institution. The Office further revises the rules to eliminate the presumption that a genuine issue of material fact created by the patent owner's testimonial evidence filed with a preliminary response will be viewed in the light most favorable to the petitioner for purposes of deciding whether to institute a review.
