A sworn document, filed by the owner of a registration, to avoid the expiration of a registration. Federal trademark registrations remain in force for 10 years, and may be renewed for 10-year periods.
Trademark owners have a window of 18 months to file a §9 Renewal Application. The §9 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 §9 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 §8 Declaration coincides with the due date of the §9 Renewal Application, these filings are commonly made together.
