The Patent Trial and Appeal Board (PTAB) must issue a final written decision on every claim challenged by a petitioner in an inter partes review (IPR) proceeding, the Supreme Court held recently.
In SAS Institute, Inc. v. Iancu, the Court not only overruled the U.S. Court of Appeals for the Federal Circuit, but also struck down the PTAB’s long-standing practice of only issuing decisions on claims for which it instituted an IPR – not necessarily all claims challenged in a petition.
Now that the PTAB must issue a final written decision on every challenged claim in a petition that is instituted, it may change its institution decision-making process when faced with, for example, long petitions that contain a multitude of challenges, says Arthur J. Bobel, a member in Leydig’s San Francisco Bay Area office.
“Prior to the Court’s decision, petitioners typically would throw everything against the PTAB wall to see what would stick, with the hope that at least one viable challenge would get them to an instituted IPR,” Bobel says. “But if the PTAB now must issue decisions on all of those weaker challenges, as opposed to being able to summarily set them aside, it may be inclined to reject such petitions and refuse to institute. That could happen even when petitions contain challenged claims that have a reasonable likelihood of being invalid.”
35 USC § 318(a) states, “If an inter partes review is instituted and not dismissed under this chapter, the Patent Trial and Appeal Board shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner and any new claim added under section 316(d).”
