Disparagement, in United States trademark law, is a cause of action that permits a party to petition the Trademark Trial and Appeal Board (TTAB) to cancel a trademark registration that "may disparage or falsely suggest a connection with persons, living or dead, institutions, beliefs, or national symbols, or bring them into contempt or disrepute". 15 U.S.C. § 1052. Unlike claims regarding the validity of the mark, a disparagement claim can be brought "at any time", subject to equitable defenses such as laches. The TTAB has interpreted the statute to give broad standing to parties who claim they may be injured by a mark - in one case, the TTAB permitted two women to seek the cancellation of a chicken restaurant's slogan, "Only a Breast in the Mouth is Better Than a Leg in the Hand".
