Section 9 Renewal Application
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 S9 Renewal Application. The S9 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 S9 Renewal Application is not filed or is filed after the grace period ends, the registration will expire.
Because the due date of the 10-year S8 Declaration coincides with the due date of the S9 Renewal Application, the USPTO created a form entitled "Combined Declaration of Use in Commerce and Application for Renewal of Registration of a Mark Under Sections 8 & 9"
