Renewal Period: The duration of trademark registrations varies from country to country, but it is typically valid for 10 years from the date of registration. Before the expiration of this initial period, trademark owners must apply for renewal to extend the protection.

Timing of Renewal: Trademark renewal applications can be filed anytime within a specific window before the expiration of the registration period. The timing for filing the renewal application varies in different jurisdictions, but it is usually between six months to one year before the expiry date.

Application Process: To renew a trademark, the owner must file a renewal application with the relevant national or regional trademark office. The renewal application typically requires providing the trademark registration number, details of the registered mark, and payment of the prescribed renewal fees.

No Changes to the Mark: The renewal process is typically straightforward and involves only confirming that there have been no substantial changes to the registered mark. If there are any changes to the mark, the owner may need to apply for a new registration instead of a renewal.

Continuous Use: Trademark renewal is contingent on the continued use of the mark in commerce. In some jurisdictions, owners may need to submit evidence of ongoing use along with the renewal application.

Grace Period: In many countries, there is a grace period after the expiration of the registration during which owners can still apply for renewal. However, there may be additional fees for late renewals.

Uninterrupted Protection: Renewing the trademark registration ensures uninterrupted protection of the mark, preventing it from becoming vulnerable to challenges or potential infringement.
