Document:
U.S. Court of Appeals for the Federal Circuit affirmed a U.S. Patent Trial and Appeal Board (PTAB) decision finding that tribal sovereign immunity does not apply to Inter Partes Review (IPR) proceedings. In so holding, the Court recognized a distinction between adjudicative proceedings brought against a state by a private party and agency-initiated enforcement proceedings.
In Saint Regis Mohawk Tribe v. Mylan Pharms. Inc., the Federal Circuit recently held that the Saint Regis Mohawk Tribe cannot claim tribal sovereign immunity to avoid an Inter Partes Review (IPR) proceeding. To reach that decision, the Court had to determine whether IPRs are closer to agency enforcement action or to an adjudicative proceeding brought against the state by a private party. If an IPR is closer to an agency enforcement action, then tribal sovereign immunity is not available as a shield to IPRs.
In denying the motion to dismiss, the PTAB determined that there was no controlling precedent or statutory basis for the application of tribal sovereign immunity in IPR proceedings. It then found that Allergan was effectively still the patent owner based on the Tribe’s license back to the drug maker—allowing for the continued control of the sale of Restasis.
Saint Regis immediately appealed the Board decision under 28 U.S.C. § 1295(a)(4)(A), relying on the “collateral order doctrine” since the Board’s decisions were not otherwise eligible for appellate review. The Board stayed the IPR pending the appeal per the Court's order granting a stay.
In upholding the Board’s decision, the Federal Circuit first determined that tribal sovereign immunity does not apply where the federal government acting through an agency engages in an investigative action or pursues an adjudicatory agency action. See, e.g., Pauma v. NLRB, 888 F.3d 1066 (9th Cir. 2018). To determine whether IPR proceedings fall under the scope of Pauma, and thus not subject to a claim of tribal sovereign immunity, the Court had to distinguish the U.S. Supreme Court’s decision in Fed. Maritime Comm’n v. S.C. State Ports Auth., 535 U.S. 743, 754–56 (2002) (“FMC”). In FMC, the Supreme Court determined that the rules and discovery procedures in FMC proceedings had significant similarities with civil litigation in federal courts. It thus found that sovereign immunity was available as a shield to the proceeding.
1. The Director has broad and complete discretion regarding whether to institute review under § 314.
The Court first noted that the Director bears the political responsibility of determining which IPRs should or should not proceed—highlighting that the Director has the wide authority to not only deny petitions on the merits, but also due to other reasons, such as administrative efficiency or based on a party’s status as a sovereign. See Wi-Fi One, LLC v. Broadcom Corp., 878 F.3d 1364, 1372 (Fed. Cir. 2018) (en banc).
The Court thus found that IPRs are more akin to cases where an agency chooses whether to institute a proceeding on information supplied by a private party.
Second, the Court noted that the Board may choose to continue an IPR proceeding or participate in appeals even if the petitioner chooses not to participate. 35 U.S.C. § 317(a); Cuozzo Speed Techs., LLC v. Lee, 136 S. Ct. 2131, 2144 (2016); see also 35 U.S.C. § 143 (granting the Director the right to intervene in appeals of Board decisions in IPRs). And in a similar manner, the Board may continue an IPR proceeding even in the absence of patent owner participation.
In the Court’s view, the Board’s ability to continue proceedings absent one or more parties, reinforces the view that IPR proceedings are an act by the agency in reconsidering its own grant of a public franchise.
3. IPR procedures limit discovery, typically preclude live testimony in oral hearings, and do not mirror the Federal Rules of Civil Procedure.
The inability of Petitioners to substantively modify an IPR petition. In contrast, the Federal Rules of Civil Procedure allow a plaintiff to make significant amendments to its complaint.
A patent owner in an IPR may seek to amend its patent claims during the proceedings— an opportunity that is not available in civil litigation. 35 U.S.C. § 316(d).
IPRs do not have many of the preliminary proceedings that exist in civil litigation, such as a claim construction hearing.
Since the Federal Rules of Civil Procedure do not apply to IPR proceedings, the discovery mechanisms in IPRs are severely limited when compared to civil litigation.
