(1) Submit a declaration of continued use of the trademark.
Even if the trademark is valid for 10 year, the registrant shall submit a use statement to the US Patent and Trademark Office within one year before the expiration of the sixth year after registration (that is, between the fifth and sixth years after registration of the trademark), stating that the trademark continues to be used in the designated goods/services in the business, or stating that the registrant has not used the trademark for other special reasons. Otherwise, the US Patent and Trademark Office will cancel the registration of the trademark at the expiration of the sixth year from the date of publication of the registration.
(2) Update
The validity period of a registered trademark in the United States is 10 years, counting from the date of registration. Within 6 months before the expiration of the validity period, the trademark owner shall submit an application for renewal and a statement of use to the United States Patent and Trademark Office.
