Documents required for trademark renewal in the United States:

1. Trademark Renewal Collection Confirmation Form-mainly to confirm the relevant information of the trademark (with official seal or signature)?

2. the applicant's identification document (copy with official seal or signature)?

3. Copy of trademark registration certificate

The registration period of American trademarks is 1 years. However, American trademarks have to submit the evidence map of trademark use again within 5-6 years after issuing the certificate, indicating that the trademark is still in use. If the evidence map is not submitted, the trademark will be automatically invalid.

the registered American trademark shall be renewed 9-1 years after the registration date, and the product use certificate shall be provided again. If the extension is neglected in the 9th-1th year, a six-month grace period will be given, but additional fees will be paid for the extension. In order to prevent unnecessary losses, it is suggested to extend the extension as early as possible during the extension period.

if the registrant misses the extension period and fails to submit relevant documents to the United States patent and trademark office as required, the trademark registration will be revoked.
