Trademark registration in Delhi is necessary for businesses looking to protect their brand identity. It prevents competitors from using a distinctive name, logo, or slogan without permission by granting the exclusive right to use it. The Trademarks Act of 1999 governs the procedure, which entails submitting an application to the Trademark Registry, followed by review and any objections. The trademark has a ten-year validity period after registration, with the possibility of renewal. Long-term business security is ensured by having a registered trademark, which also increases brand credibility and offers legal protection against infringement.
