If a registered trademark is not used for special reasons, it shall explain the reasons and indicate that it will not give up the use of the trademark, otherwise it will be revoked.
2. If the registrant uses its registered trademark in the United States for five consecutive years from the date of trademark registration, he can obtain the "undisputed" right through application. Once the "indisputable" right is obtained, the registrant has conclusive evidence of exclusive use of its trademark in trade, and no third party can request cancellation of the trademark registration on the grounds that the trademark lacks distinctiveness.
3. The term of validity of a registered trademark in the United States is 10 year, and the certificate of use or the reason for not using it is still required for each renewal, otherwise the United States Patent and Trademark Office will cancel the registration of the trademark.
4. One year before the expiration of the American trademark, the trademark renewal will be missed, and there will be a trademark renewal for half a year after the expiration. After the expiration of the American trademark, it should be reviewed in time to ensure the exclusive right to use the trademark.
