The proprietor of the trademark has to file a prescribed form for renewal before the Registrar. This application can be filed on or before 6 months from the date of expiration of the trademark registration.
1 – 3 months before the expiration of the registration, if no application for renewal has been filed, then the Registrar shall send a notice to the proprietor informing him of the upcoming renewal date. Keep in mind that no trademark can be removed, if notice of renewal has not been served.
Along with the application for the renewal, the proprietor has to pay renewal fees as prescribed. Failure to pay such fees will cause the removal of the trademark from the register.
