Introduction

A Division Bench of the Bombay High Court recently considered an appeal arising from the refusal of interim injunctive relief in a trademark dispute between Minco India Private Limited and Minco India Flow Elements Private Limited. The case presents an intersection of trademark law principles with family business dynamics, highlighting how suppression of material facts and acquiescence can defeat even a registered proprietor’s claim at the interim stage.

Factual Background

The dispute originates from a commercial suit instituted by the plaintiff, Minco India Private Limited, alleging trademark infringement, passing off, and related claims against the defendant, Minco India Flow Elements Private Limited. The plaintiff sought to restrain the defendant from using the mark “MINCO” in connection with its business.

The plaintiff asserted that it had been engaged in the manufacture and supply of gauges and related instruments since 1982 and had continuously used the mark “MINCO INDIA” since then. Over decades, the mark was claimed to have acquired substantial goodwill and distinctiveness, becoming exclusively associated with the plaintiff’s business.

In February 2024, the plaintiff claimed to have discovered that the defendant was using the identical mark “MINCO” for similar industrial products such as flow meters. Alleging dishonest adoption and prior knowledge on the defendant’s part, the plaintiff pointed to an instance of confusion involving a third-party complaint wrongly attributed to it. On this basis, the suit and accompanying application for interim injunction were filed.

Order of the Single Judge

The Learned Single Judge declined to grant interim relief. While acknowledging certain aspects of the plaintiff’s case, the Court held that the plaintiff was not entitled to equitable relief.

The refusal was primarily grounded in:

1. Suppression of material facts and prima facie false statements by the plaintiff;
2. The defendant’s prior and continuous use of the mark since 2012;
3. The defendant’s substantial business operations and turnover; and
4. The plaintiff’s failure to establish a prima facie case of passing off, particularly in the absence of pleadings or evidence demonstrating misrepresentation.

Accordingly, the balance of convenience was found to favour the defendant.

Appeal Before the Division Bench

Aggrieved by the refusal of interim relief, the plaintiff preferred an appeal, contending inter alia:

1. The Single Judge erred in denying relief on the ground of suppression, relying on background facts such as the historical relationship between the parties.
2. The alleged omissions relating to a 2012 no-objection certificate (NOC), the plaintiff’s directorial role until 2015, and the date of knowledge did not constitute material suppression sufficient to disentitle equitable relief.
3. The plaintiff, being the prior user since 1982 and a registered proprietor, held superior rights in the mark.
4. The defendant’s reliance on concurrent use was misplaced, particularly as its 2022 trademark application was filed on a “proposed to be used” basis.
5. Mere delay does not amount to acquiescence unless it reflects implied consent creating enforceable rights, which was absent in the present case.

Defendant’s Submissions

The defendant, in response, argued:

1. The plaintiff had not made full disclosure of the relationship between the parties, reducing it to a bare reference despite deep business and familial ties.
2. The products in question were customized, specification-based industrial goods, often not bearing trademarks, and were sold under corporate names rather than as branded products.
3. The parties were brothers, and their businesses originated from a common family enterprise, later divided but continuing similar operations.
4. The defendant had adopted the name “MINCO” in 2012 pursuant to a no-objection from the plaintiff, and both parties had coexisted for over a decade.
5. The plaintiff’s prolonged inaction, despite knowledge, amounted to acquiescence, and the present suit disrupted a long-standing understanding of coexistence.

Findings of the Division Bench

The Division Bench reiterated the settled principle that an appellate court should not interfere with the exercise of discretion by a trial court unless it is shown to be arbitrary, perverse, or contrary to settled principles.

• Knowledge and Suppression of Material Facts

The Court found that the plaintiff’s assertion of acquiring knowledge only in February 2024 was prima facie incorrect. The records evidence that:

1. A no-objection certificate in 2012 permitting the defendant to adopt the name “MINCO”
2. The fact that both brothers served as directors in each other’s companies until 2015; and
3. Continued proximity and shared clientele.

In light of these facts, the plaintiff’s portrayal of the defendant as an unrelated third party was held to be misleading, amounting to suppression of material facts.

• Acquiescence as a Complete Defence

The Court held that the defendant’s open and continuous use of the mark since 2012, coupled with the plaintiff’s knowledge and inaction, constituted acquiescence.
This long-standing use of the defendant was found sufficient to disentitle the plaintiff from interim relief, particularly given the equitable nature of such relief.

• Scope of Trademark Rights in Context

While acknowledging that registration confers exclusivity, the Court clarified that such rights are not absolute and must be assessed in context.

In the present case:

1. Both entities originated from the same family business;
2. Their operations were historically intertwined; and
3. The defendant’s adoption of the mark was not in the nature of a third-party encroachment.

Accordingly, the plaintiff’s statutory rights could not be enforced in isolation from these surrounding circumstances.

• Absence of Prima Facie Case and Likelihood of Confusion

The Court also noted:

1. The goods involved were specialized, made-to-order industrial products, reducing the likelihood of confusion;
2. The plaintiff relied on only a single instance of alleged confusion; and
3. There was insufficient material to establish misrepresentation or passing off.

• Balance of Convenience

Given the defendant’s long-standing use since 2012 and the plaintiff’s inaction, the balance of convenience clearly favoured the defendant. Granting an injunction at this stage would disrupt an established business practice.

Conclusion

In view of the above, the Division Bench upheld the order of the Learned Single Judge and dismissed the appeal. The refusal of interim relief was affirmed on the grounds of:

1. Suppression of material facts, and
2. Acquiescence arising from prolonged inaction despite knowledge.

Comment

The decision reinforces that interim relief in trademark disputes is not granted as a matter of course, even in favour of a registered proprietor. Courts will closely scrutinize the conduct of the parties, especially in cases involving longstanding relationships and shared business origins. Where a plaintiff has acknowledged the defendant’s use over time and failed to make full and frank disclosures, equitable relief may justifiably be denied. The judgment thus highlights that delay, coupled with acquiescence and suppression of facts, can outweigh statutory rights at the interlocutory stage.
