Trademark Trial and Appeal Board Law and Legal Definition

Trademark Trail and Appeal Board (TTAB) is a body within the U.S. Patent and Trademark Office (USPTO) that hears and decides certain kinds of cases involving trademarks. These include appeals from decisions by USPTO examining attorneys denying registration of marks, and opposition proceedings filed against trademark applications. TTAB panels hear hundreds of claims each year asserting that trademarks should not be registered because they are generic, disparaging, or confusingly similar to existing marks. Decisions of the TTAB can be appealed to a U.S. district court, or the U.S. Court of Appeals for the Federal Circuit.

The TTAB also hears certain kinds of inter parties proceedings, including oppositions to registration, cancellation proceedings against registered marks, and concurrent use proceedings where a party alleges its mark is entitled to joint registration.
