Prior User and Subsisting Registration Prevails in Trademark Dispute: Delhi High Court

The High Court of Delhi has reiterated the legal primacy of prior user and valid registration in trademark disputes, ruling against an appellant seeking to restrain a defendant from using a contested brand name. The Division Bench, comprising Justice C. Hari Shankar and Justice Om Prakash Shukla, dismissed the appeal filed by Sana Herbals Private Limited, emphasizing that in commercial litigation, established legal principles regarding priority of use outweigh equitable claims of accumulated goodwill.

A Complex History of Ownership

The dispute centered on the trademark 'NOKUF', used for pharmaceutical cough syrups. Sana Herbals Private Limited initiated a lawsuit against Mohsin Dehlvi and Dehlvi Remedies Pvt Ltd, alleging trademark infringement and passing off. The appellant argued that it had built substantial goodwill in the 'NOKUF' brand over two decades and held a registered trademark for 'NOKUFSYRUP'. Furthermore, the appellant relied on an alleged 1999 Assignment Deed to assert exclusive rights to the 'NOKUF' mark.

Conversely, the respondents maintained that they were the original adopters and users of the 'NOKUF' mark, with roots dating back to 1994, and had secured registration for the mark in September 2020 (with effect from 1996). The respondents disputed the validity of the alleged Assignment Deed and cited periods of operational hardship—including a devastating fire—as reasons for the intermittent nature of their business activities.

Core Legal Questions

The court was tasked with addressing whether the appellant—who had used the mark openly for years—could secure an injunction against a respondent who held an earlier registration and a history of prior use, despite a significant period of market inactivity. The bench focused on whether a "passing off" action could be sustained by the appellant when the respondents were the initial adopters of the trademark.

The Limits of Equity in Commercial Law

While acknowledging the appellant's argument that they had "built up a reputation" over a quarter-century, the Court underscored that intellectual property rights are governed by statute and precedent. The judges clarified that in a passing-off action, the plaintiff must prove that their goodwill in the mark predates the defendant’s adoption of said mark.

The Court relied heavily on the Supreme Court ruling in Toyota Jidosha Kabushiki Kaisha v. Prius Auto Industries Ltd and * Neon Laboratories v. Medical Technologies Ltd *. The bench noted that despite the appellant’s investment in the mark, the respondents’ status as the prior user and registered owner established an "unassailably favourable" position under the law.

Key Observations

• On the Nature of Infringement: "No infringement action can lie against a registered trade mark, though an action for passing off is maintainable."
• On First User Rule: "Section 34 of the Trade Marks Act... palpably holds that a proprietor of a trade mark does not have the right to prevent the use by another party of an identical or similar mark where that user commenced prior to the user or date of registration of the proprietor."
• On the Primacy of Law: "Equity, in matters of commerce, has to yield place to the dictates of the law."
• On Goodwill: "Goodwill in the plaintiff’s mark has, therefore, to be shown to exist prior to commencement of user of the mark by the defendant."

Decision and Implications

The High Court upheld the dismissal of the interim injunction application. The ruling solidifies the principle that subsequent, even extensive, use of a brand name by one party does not extinguish the rights of an earlier registrant or prior user, unless the latter has clearly abandoned the mark. This judgment serves as a vital reminder for businesses to conduct thorough due diligence regarding the origins and registration status of a trademark before investing heavily in brand building, as the law remains strictly protective of the "first in the market" test.
