Trademark renewal in Delhi helps companies extend their registered trademark period after its first ten years under the Trade Marks Act of 1999. A business must file its TM-R form alongside the necessary fee payment before the current expiration date but within the six-month period. Renewal keeps your sole proprietorship of name, logo, and slogan secure and under legal protection. When businesses renew their registrations on time they get both identity protection and market position protection and avoid any difficulties. If you miss the renewal, others might use your brand, so renewing ensures your trademark stays safe.
