A Patent and Trademark Office director confirmation may solve some problems, but it’s not yet clear how discretionary review will continue to evolve.
The U.S. Patent and Trademark Office’s inter partes review procedure is a popular avenue for challenging the validity of a patent outside of litigation. These procedures are overseen by a panel of three administrative patent judges (APJs) on the Patent Trial and Appeal Board (PTAB) at the Patent Office. In United States v. Arthrex, the Supreme Court ruled that the “unreviewable authority” of APJs to conduct adversarial proceedings for challenging the validity of a patent violated the Constitution’s Appointments Clause. The Supreme Court also ruled that the appropriate remedy was to give the director of the Patent Office the discretion to review those APJ decisions.
Arthrex is the owner of U.S. Patent No. 9,179,907 (we’ll refer to it as the ’907 patent) which relates to a surgical device for reattaching soft tissue to bone without tying a knot. Arthrex claimed that Smith + Nephew infringed the ’907 patent, and the PTAB subsequently invalidated the patent in an inter partes review proceeding. On appeal, the U.S. Court of Appeals for the Federal Circuit ruled that the appointment of APJs violated the Appointments Clause. To remedy the violation, the Federal Circuit stripped away the APJ’s tenure protections and sent the case back to the PTAB for a new hearing before a different panel of APJs. After the Federal Circuit denied requests for rehearing en banc and before the case went back to the Patent Office, the parties each sought Supreme Court review.
The Supreme Court took the case and agreed that there was a violation of the Appointments Clause, specifically taking issue with the fact that “Congress has assigned APJs ‘significant authority’ in adjudicating the public rights of private parties, while also insulating their decisions from review and their offices from removal.”
The Supreme Court, however, fashioned a new remedy for the constitutional violation, holding “[d]ecisions by APJs must be subject to review” by the director of the Patent Office because Congress vested the director with the “powers and duties” of the Patent Office and tasked the director with supervising APJs. The Court held that the director may review final PTAB decisions (i.e., Final Written Decisions) and issue decisions on behalf of the PTAB.
Following the Supreme Court’s decision, the Patent Office provided a procedure for director review. The director may review a Final Written Decision on the director’s own accord or, more likely, the director may review a Final Written Decision in response to a party’s request for director review. Once the request is submitted, the director may deny, or partially or entirely grant the request.
The director has since received more than 100 requests for review. In Proppant Express Invs. v. Oren Techs. (IPR2018-00733, Paper No. 94), the director vacated and remanded the PTAB’s finding of unpatentability because it failed to give the necessary weight to objective evidence of nonobviousness. In Ascend Performance Materials Operations v. Samsung SDI (IPR2020-00349, Paper No. 57), the director similarly vacated and remanded another unpatentability finding because the PTAB failed to address the claims in view of their corresponding priority date. With the exception of these few outliers, petitions for director review under Arthrex have been largely fruitless, with the director denying most requests.
The current director review process is conducted under interim procedures. For now, a party receiving a Final Written Decision must choose to request either director review or rehearing by the original PTAB panel — it may not request both. Further changes to the review process may result in additional guidance for parties and the director.
