Step 3. You file a Section 8 declaration. Before the end of the first six-year period after the registration date, or within six months of the expiration of the sixth year with an additional fee, you must file a Declaration of Use or Excusable Nonuse under Section 8 and pay applicable fees. This declaration must include a verified statement that your trademark is in use in commerce, along with evidence showing that use. If you don’t file this declaration, your registration will be canceled. The Section 8 declaration may be filed combined with the optional Section 15 declaration of incontestability (see step 3a for more information about this optional filing). Every 10 years go to step 4.
