The validity period of trademark registration in India is 10 years, calculated from the date of trademark application. Of course, renewal can also be carried out before the expiration of the limited period. Each renewal is valid for 10 years. Note that the application for trademark renewal needs to be submitted within 6 months before the expiration of the trademark. In addition, there is a 6-month grace period for trademark renewal. If renewal is not applied for after the grace period, the trademark will be deleted from the trademark register. If the registrant wants to continue to use the trademark within one year of its expiration, the registrant can submit an application for restoration of registration and renew the trademark. However, if you exceed the one-year period, you may only resubmit your registration application.
