The Trademark Trial and Appeal Board (TTAB) is an administrative tribunal within the United States Patent and Trademark Office (USPTO) established in 1958. 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.
