In September 2018, the Patent Office created the Precedential Opinion Panel (or “POP”) to increase transparency and predictability of proceedings before the PTAB by establishing precedent that would guide all PTAB judges. In March 2019, the POP released its first opinion, which held that the PTAB may, in limited circumstances, join both a petitioner to a proceeding in which it is already a party and join new issues to an existing proceeding.
This past year, the Supreme Court in SAS Institute v. Iancu held that once the PTAB institutes an IPR trial its subsequent final written decision must address all claims challenged in the petition. The Court explained that its holding was compelled by a plain reading of 35 U.S.C. § 318(a), which states that the PTAB must issue a final written decision on “any patent claim challenged by the petitioner.” SAS Institute did not decide, however, whether the PTAB’s final written decisions must also address all grounds raised in a petition. The Federal Circuit has subsequently provided a clearer answer.
