Domain names can attract trademark protection where Internet use of a well-known mark is likely to mislead users and cause passing off.

Trademark protection was held to extend to domain names used in Internet commerce where their use is likely to mislead users into believing an association with the mark owner. The court noted the plaintiff's established reputation in the TATA mark and the defendants' unrefuted registration and use of multiple domain names incorporating that mark. Applying passing off principles, it treated domain names as more than mere addresses and recognised that their misuse can cause deception and dilution. Permanent injunctive relief was granted, restraining the defendants from using the impugned domain names or any identical or deceptively similar mark or name, including use that would dilute the plaintiff's mark.

Issues: Whether the plaintiff was entitled to a permanent injunction restraining the defendants from using domain names containing the plaintiff's mark TATA and from otherwise dealing in goods or services under identical or deceptively similar marks on the Internet.

Analysis: The plaintiff established ownership and long-standing reputation in the mark TATA and proved that the defendants had registered and used multiple domain names incorporating that mark. The defendants remained ex parte and led no rebuttal evidence. Relying on prior decisions on Internet-based passing off, the Court held that domain names are entitled to trademark protection because they function as more than mere addresses and may mislead users into believing that the site or business is connected with the trade mark owner. The Court applied the principles of passing off and held that trademark law extends to cyberspace, including services offered through domain names.

Conclusion: The plaintiff was entitled to permanent injunctive relief, and the defendants were restrained from using the impugned domain names or any mark/name identical with or deceptively similar to TATA, including any use causing dilution of the mark.

Ratio Decidendi: Domain names used in Internet commerce are protectable as trademarks where their use is likely to cause passing off or dilution of a well-known mark.
