Rights in a federally-registered trademark can last indefinitely if the owner continues to use the mark on or in connection with the goods and/or services in the registration and files all necessary documentation in the USPTO at the appropriate times. In general, the owner of a registration must periodically file:

•  Affidavits of Continued Use or Excusable Nonuse under 15 U.S.C. §1058; and

•  Applications for Renewal under 15 U.S.C. §1059.

Forms for filing these documents are available at http://www.uspto.gov/teas/ . For further information on maintaining a federal trademark registration, please contact the Post Registration Division at (703) 308-9500.
