# Trademark Trial and Appeal Board

The Trademark Trial and Appeal Board (TTAB) is an administrative tribunal within the United States Patent and Trademark Office (USPTO). The TTAB is empowered to determine the right to register a trademark. It has no authority to determine the right to use one, nor broader questions of infringement, unfair competition, damages or injunctive relief. The TTAB decides ex parte appeals from decisions by USPTO Examiners denying registration of marks, and inter partes proceedings challenging the registration of marks. Decisions of the TTAB may be appealed to a United States district court, or to the United States Court of Appeals for the Federal Circuit.
Practices and procedures for litigating before the TTAB are governed by the Trademark Rules of Practice and the Federal Rules of Civil Procedure. The Trademark Trial and Appeal Board Manual of Procedure (TBMP) is an important guide to practice before the TTAB.

## Judges of the TTAB

The Administrative Trademark Judges of the Trademark Trial and Appeal Board (TTAB) are appointed by the United States Secretary of Commerce in consultation with the Under Secretary of Commerce for Intellectual Property. Each appeal and adversarial proceeding is heard and decided by at least three judges of the TTAB. There are currently twenty-seven judges sitting at the TTAB (as of March 2025), as follows:
