The U.S. Supreme Court preserved inter partes review proceedings before the Patent Trial and Appeal Board by bringing the USPTO director into the mix. Our Intellectual Property Group examines the decision, its impact on current PTAB proceedings, the likely backlog created by the decision, and potential options for the PTAB in the future.
- Inter partes review proceedings will continue
- The USPTO director will become a new stop for further review
- How will the PTAB operate going forward?
The key takeaway is that the 100+ cases that are stayed before the PTAB, and countless more that may be remanded, will proceed through director review and, ultimately, the appeals process. The decision also provides current PTAB litigants with another level of review should they be dissatisfied with the outcome of their PTAB proceedings. In both cases, however, an expected short-term backlog before the director will likely serve to delay what are supposed to be quick alternatives to patent litigation.
Supreme Court Decision
A patent that has been issued by the USPTO is presumed valid until proven otherwise. Before 2012, the main mechanism to challenge the validity of an issued U.S. patent was to contest it in federal district court. With the America Invents Act (AIA), however, Congress created a new instrument to invalidate patents—inter partes review (IPR). Though there are many differences between IPR proceedings and district court patent litigation, the relevant distinction here is that the fate of the patent in an IPR proceeding is decided by a panel of three members from the PTAB.
The PTAB is primarily made up of administrative patent judges (APJs). Unlike judges in federal district courts, APJs are officers of the executive branch. They are appointed by the Secretary of Commerce, who in turn is appointed by the President. APJs are generally overseen by the USPTO director (who is also appointed by the President), but they cannot be removed without cause. Importantly, after the PTAB has issued a final written decision, it is the PTAB, and not the director or the Secretary, that has the sole authority to grant rehearing.
The Federal Circuit appeal
At the heart of Arthrex is whether these APJs have constitutional authority to issue final written decisions, which are not reviewable by a superior officer within the executive branch. On appeal at the Federal Circuit, this issue boiled down to whether APJs are principal officers or inferior officers. A principal officer is one who plays a critical enough role in the executive branch such that they must be appointed according to the Appointments Clause of the U.S. Constitution. Principal officers, therefore, must be appointed by the President with the advice and consent of the Senate. Inferior officers, on the other hand, do not need to be appointed by the President.
The Federal Circuit held that IPR decisions by the PTAB were unconstitutional because APJs are principal officers and had been unconstitutionally appointed. The remedy set forth by the Federal Circuit was to invalidate the APJs’ tenure protections, which allowed for APJs to be removable at will by the Secretary of Commerce. According to the Federal Circuit, this fix would allow IPRs to proceed constitutionally.
The Court’s opinion
The Supreme Court approached the issue differently. Although not explicitly enumerated, the Supreme Court answered three questions in its opinion: (1) is it constitutional for the PTAB to issue final written decisions in the way it has been; (2) why or why not; and (3) if not, what happens now? The Court agreed with the Federal Circuit on question (1)—the answer is no, the PTAB does not have constitutional authority to issue final written decisions in the way it has been.
It is with questions (2) and (3) that the Supreme Court diverges from the Federal Circuit. The Supreme Court held that because APJs are appointed according to the procedures of an inferior office (and not via the Appointments Clause procedure), APJs do not have the authority to issue a decision that is unreviewable by a superior officer within the executive branch. However, “Congress unambiguously specified that ‘[o]nly the Patent and Trial Appeal Board may grant rehearings.’” According to the Court, the solution to this constitutional violation is to sever the portion of the statute that gives the PTAB the sole authority to grant rehearing and to specifically place such authority with the USPTO director.
Ultimately, the Court’s decision protects the constitutionality of IPR proceedings, but adds an additional layer of review. The Court remanded to the USPTO director to consider whether to reevaluate the finding of unpatentability made by the PTAB.
Of note, there were several concurrences and dissents. Justice Gorsuch concurred with the Court’s opinion that APJs are unconstitutionally appointed but dissented from the Court’s invocation of the severability doctrine and proposed remedy, arguing that the Court has overstepped its authority into the legislative realm. Justice Thomas, joined by Justice Breyer, Justice Sotomayor, and Justice Kagan in part, dissented with the Court’s opinion, determining that APJs are already functioning as inferior officers, so no remedy is required. Finally, Justice Breyer, joined by Justice Sotomayor and Justice Kagan, dissented from the Court’s new test (and agreed with Justice Thomas’s discussion on the merits in his dissent) but concurred with the Court’s remedial holding based on the results of the Court’s new test. This fractured opinion provides openings for further legislative consideration.
What Happens Now?
The Arthrex decision does not provide much guidance on the form of the new procedures other than stating that the director “may review final PTAB decisions and, upon review, may issue decisions himself on behalf of the Board.” The Arthrex decision likens this review to the model implemented by the Trademark Trial and Appeal Board in the Trademark Modernization Act of 2020. While the USPTO is still determining what such review in both adjudicative bodies would look like, without engaging in overspeculation, we would expect the director to implement a system similar to the Precedential Opinion Panel, albeit without the panel itself. Regardless of the mechanics involved in implementing review, we expect changes to PTAB operations and further anticipate that there will be several considerations in approaching rehearing requests under the anticipated procedures.
An initial consideration is that the Arthrex decision is limited to “final PTAB decisions,” so any resulting rule changes should not affect procedures for requesting rehearing for institution decisions. We expect the success rate for rehearing requests at institution to remain steady. In contrast, because the panel issuing the final written decision will no longer be reviewing itself for error, we expect that the historically low success rate for rehearing requests after the final written decision to increase. With such an increase, parties may come to see rehearing requests not as a last-ditch effort but rather as a viable attempt at overturning unfavorable decisions, similarly causing an increase in rehearing request filings.
More importantly, director-driven review will give requesting parties another bite at the apple. While rehearing requests have been an option for parties after the final written decision, due to the low success rate and barring clear error, the most viable option to date has been to appeal the PTAB decision to the Federal Circuit. Under the anticipated rehearing procedures, parties will have the opportunity to have the final written decision reviewed by the director, but all decisions would remain appealable to the Federal Circuit. On the other hand, the likely increase in granted rehearing requests may similarly increase the number of appeals from the PTAB to the Federal Circuit because the additional review procedure may generate additional material for appeal.
In addition to increasing the Federal Circuit caseload, new review procedures may also create yet another backlog at the USPTO. The PTAB already has a heavy caseload, and creating an extra layer of review procedures will only add to it. Similarly, the director has many other duties beyond participation in the PTAB, and the Supreme Court’s new requirements will only add to those duties. These additions will ultimately create a backlog in all director-driven procedures, at least until a new system is developed. So, while the new review procedures will be an interesting, if not positive, change, we expect that any proceedings under review will be stalled for many months.
Should Congress choose to intervene, however, these changes will be a moot point. As alluded to by Justice Gorsuch, Congress can and may enact legislation to change the outcome of the Arthrex decision. Taking it further, Justice Thomas’s dissent practically challenges Congress to intervene, proclaiming that the Court’s opinion amounts to holding that Congress violated the Constitution by creating the APJ position. Ultimately, unless or until Congress gets involved, the Supreme Court’s decision in Arthrex will require the PTAB to overhaul its review procedures, resulting in significant changes to how parties approach not only rehearing requests but also IPR proceedings as a whole.
