Trademark registration in India lasts 10 years, after which you must renew your trademark registration. The 10 years are counted from the day of application. Trademark renewal preserves those rights which are only available to a registered mark. In case the proprietor fails to renew the trademark, then he shall lose all the protection that comes along with registration. The registrar of trademarks will send you a letter of a reminder of the expiry of the trademark 6 months prior to its expiry. > Application for renewal of the trademark can be filed on or before 6 months, before the expiry of the registration in a prescribed form before the Registrar along with the requisite renewal fee.> A renewal request can also be filed within 6 months after the expiry of the renewal date along with the requisite late renewal fees.> If the request is not filed and the fees is not paid within the aforementioned periods, the trademark is liable to be removed from the Register.
