An administrative hearing body under the auspices of the U.S. Patent and Trademark Office. The TTAB hears matters concerning federal registration of a mark and the cancellation of federal registrations. Primarily, the TTAB hears appeals from final refusals issued by a Trademark Examining Attorney.

Decisions by the TTAB can be reconsidered by the Board if a request is filed within one month after the decision.  Appeals thereafter can be brought to the Federal Circuit Court of Appeals or to federal district court.

Trademark attorneys do not need a special license or certification to practice in front of the TTAB, as is required when practicing patent law in front of the USPTO.
