Non-Disparagement of Native American Persons or Peoples in Trademark Registration Act of 2013

Non-Disparagement of Native American Persons or Peoples in Trademark Registration Act of 2013 - Amends the Trademark Act of 1946 to conclusively presume that a mark that uses the term "redskin" or any derivation of that term consists of matter which may disparage persons if: (1) it has been, is, or is intended to be used in commerce in connection with references to or images of Native Americans; or (2) the Director of the United States Patent and Trademark Office (Director) determines that the term as included in the mark is commonly understood to refer to Native Americans. (The possibility that a mark disparages persons is grounds for refusing its registration.)

Requires the Director to cancel the registration of a mark containing the term "redskin" or any derivation of that term if: (1) it has been or is used in commerce in connection with references to or images of Native Americans, or (2) the Director determines that the term as included in the mark is commonly understood to refer to Native Americans.
