The trademark registration certificate needs to be renewed in advance before it expires, and the specific renewal period varies from country to country. Generally speaking, it is common to renew a trademark registration certificate about 6 months before its expiration to 1 year.

The advance notice of the renewal period is to give the trademark owner enough time to prepare and submit the renewal application, so as to ensure the continuation of the trademark protection right.

It is suggested that trademark holders start the renewal procedure as soon as possible before the expiry of the Trademark Registration Certificate, so as to avoid the loss of trademark rights and interests caused by delaying or forgetting the renewal.

For specific renewal procedures and requirements, you can consult your local trademark office or trademark agency for accurate information and procedures applicable to your country or region.
