Trademark registration in India allows individuals and companies to register words, phrases, symbols or designs that distinguish their goods and services from others. The registration provides legal protection and exclusive rights to use the trademark for 10 years, with the option to renew. The registration process involves filing an application, examination, publication, possible opposition, registration if approved, and issuance of a registration certificate. While an application is pending, the TM symbol can be used, and the ® symbol requires an active registration.
