Background

Philip Morris petitioned to cancel four federal registrations covering cigarette and tobacco marks, alleging abandonment through nonuse or naked licensing. While the cancellation was pending, IP Services International transferred the registrations to Sycuan Tribal Development Corporation, an entity associated with the Sycuan Band of the Kumeyaay Nation. Sycuan moved to dismiss on tribal-sovereign-immunity grounds. The issue was one of first impression for the Trademark Trial and Appeal Board.

The Court’s Holding

In a precedential order, the TTAB held that tribal sovereign immunity does not apply to inter partes proceedings before the Board and denied Sycuan’s motion. Federal trademark registration is a public benefit administered by the USPTO, and opposition and cancellation proceedings allow the agency to reconsider whether a registration should remain on the federal register. The Board decides only registration rights; it cannot impose personal liability, damages, or an injunction.

The Board treated its proceedings as hybrid administrative adjudications rather than ordinary private civil suits. It relied on Federal Circuit decisions holding that tribal and state immunity do not block Patent Trial and Appeal Board review, along with the TTAB’s own precedent rejecting state immunity in opposition proceedings. A tribe that chooses federal registration receives its benefits subject to the Lanham Act’s cancellation machinery. Allowing immunity would also invite private registrants to shield questionable registrations by assigning them to tribal entities.

Key Takeaways

  • Tribal sovereign immunity cannot defeat a TTAB opposition or cancellation proceeding.
  • The ruling concerns the right to maintain federal registrations, not the right to use the marks or liability for infringement.
  • The Board did not decide whether Sycuan qualified as an arm of the tribe or had waived immunity because immunity was unavailable in the first place.
  • The cancellation case remains pending; the Board has not yet decided Philip Morris’s abandonment and naked-licensing claims.

Why It Matters

The precedential order closes a potential path for insulating federal trademark registrations from administrative review. It aligns the trademark system with patent-review precedent and preserves the USPTO’s ability to police the accuracy and integrity of the federal register regardless of who owns a challenged registration.
