Disparagement, in United States trademark law, was a statutory cause of action which permitted a party to petition the Trademark Trial and Appeal Board (TTAB) of the Patent and Trademark Office (PTO) 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".[1] In 2017, the Supreme Court struck down the disparagement provision as unconstitutional in Matal v. Tam.
