Hello, the validity period of a U.S. trademark is 10 years, calculated from the date of application, but an affidavit of use needs to be submitted in the 5th to 6th years after the registration date, and renewal is required in the 9th to 10th year to maintain it. The trademark remains valid.

If you need to continue to use it, you need to renew the US trademark: US trademarks are different from Chinese trademarks. The following procedures are required for renewal:

1) 5-6th day after registration A declaration of use is required to maintain the validity of the trademark.

2) Evidence of use needs to be submitted and renewed in years 9-10 to maintain the validity of the trademark.

The above answers are for your reference. I hope they can help you. You are welcome to like us and follow us. Thank you.
