The U.S. Trademark Law stipulates that a successfully registered trademark must submit a proof of use to the U.S. Patent and Trademark Office within the fifth and sixth years from the date of trademark registration to maintain the validity of the registered trademark. If a registered trademark is not used for special reasons, the reasons should be explained and the use of the trademark should be stated, otherwise the trademark will be revoked.

If you fail to renew a registered U.S. trademark in time, you will lose the exclusive right to the trademark, and the trademark you have worked so hard to promote will be in vain
