A registered trademark shall be valid for a period of 10 years from the date of initial application. It has to be renewed every 10 years thereafter by making the required application along with the fees. Don’t worry! You don’t have to reapply for the entire registration process every 10 years. You can get it renewed 6 months before expiry by just paying the nominal renewal fees. You even get a reminder from the Trademark Registry itself telling you to renew it. If you keep renewing it you can keep the trademark with you for a lifetime.
