U.S. trademark law Edit
A renewal application is a sworn document, filed by the owner of a registration, to avoid the expiration of a registration. Federal trademark registrations issued on or after November 16, 1989, remain in force for 10 years, and may be renewed for 10-year periods. Trademark registrations issued or renewed prior to November 16, 1989 remain in force for 20 years, and may be renewed for 10-year periods. Trademark owners have a total of 18 months to file a renewal application. The renewal application may be filed one year prior to the registration expiration date or during the 6-month grace period immediately after the date of expiration. If the renewal application is not filed or is filed after the grace period ends, the registration will expire.
