Interim Injunction in Section 29(5) Trade-Name Infringement: Suppression, False “Date of Knowledge”, and Long Acquiescence Defeat Equity

1. Introduction

The Bombay High Court (Ordinary Original Civil Jurisdiction) decided an interim application in a commercial IP suit between Minco India Private Limited (Plaintiff) and Minco India Flow Elements Private Limited (Defendant). The suit alleged infringement of trademark and passing off, founded primarily on the Defendant’s use of the word “MINCO” as part of its trade name.

The Plaintiff claimed continuous use of “Minco India” since 1982 and relied on its registration in Class 9 obtained on an application filed in June 2023 with a user claim dating back to 1982. The alleged infringement was discovered, according to the plaint, in February 2024, when a third-party email complained of a defective product that the Plaintiff said was actually supplied by the Defendant.

The Defendant resisted interim relief on multiple grounds: (i) suppression and a false pleaded date of knowledge, (ii) long and open use of “MINCO” as part of its trade name since 2012, (iii) consent/No Objection for a 2012 name change, (iv) the Plaintiff’s prolonged inaction amounting to acquiescence, and (v) limited likelihood of confusion given a niche, customised industrial market.

Key Issues

  • Whether use of “MINCO” in the Defendant’s trade name could amount to infringement of the Plaintiff’s registered mark “MINCO INDIA” under Section 29(5) of the Trade Marks Act, 1999.
  • Whether the Plaintiff was entitled to interim injunction despite alleged suppression/false pleading and long delay.
  • Whether a prima facie case of passing off (goodwill, misrepresentation, damage) was made out.
  • How equity and balance of convenience operate where the Defendant has traded openly for many years and built substantial turnover.

2. Summary of the Judgment

The Court dismissed the interim application and refused to restrain the Defendant from using “MINCO” as part of its trade name. While noting the Plaintiff’s proprietary interest in “MINCO INDIA”, the Court held that interim relief is equitable and discretionary. On the facts, the Court found:

  • The Plaintiff had knowledge of the Defendant’s use of “MINCO” as part of its name at least by 2015 (and prima facie since 2012), contrary to the plaint’s pleaded discovery in 2024.
  • There was prima facie suppression of material facts and false statements on oath, undermining the Plaintiff’s equity.
  • The Defendant’s adoption of the name (including “MINCO”) was, prima facie, not shown to be dishonest or fraudulent, particularly in light of corporate resolutions and the Plaintiff’s No Objection in 2012.
  • The Defendant had built a substantial business over years (sales turnover asserted at about Rs. 111 crores since 2012), tilting balance of convenience against an injunction.
  • A prima facie case of passing off was not made out; in particular, misrepresentation and resulting damage were not shown, and the “confusion” email was treated as doubtful/insufficient in context.

3. Analysis

3.1 Precedents Cited

(a) M/s. Power Control Appliances and Ors. v. Sumeet Machines Pvt. Ltd.

The Court relied most concretely on this authority to articulate the doctrine of acquiescence—distinguishing it from mere delay. Quoting paragraph 26 (as reproduced in the judgment), the Court emphasised:

  • Acquiescence is “sitting by” while another invades rights and spends money building a business.
  • It implies positive conduct inconsistent with exclusivity, and may justify an inference akin to licence/consent.
  • A plaintiff cannot wait until a defendant’s trade becomes significant and then seek to “crush” it by injunction.

Applying this, the Court treated the Plaintiff’s long inaction (knowledge at least by 2015, suit in 2024/2025) as fundamentally weakening the claim for interim restraint.

(b) M/s. Hindustan Pencils Pvt. Ltd. v. M/s. India Stationery Products Co. and Anr.

The Plaintiff invoked this decision to argue that delay does not defeat injunction where the defendant’s adoption is tainted. The Court, however, held it did not assist because, on the present material, the Defendant’s adoption was not shown to be dishonest/fraudulent at the interim stage, especially given the 2012 corporate resolutions and subsequent conduct.

(c) Pidilite Industries Limited v. Jubilant Agri and Consumer Products Limited and Midas Hygiene Industries (P) Ltd. v. Sudhir Bhatia and Ors.

These authorities were cited to support the general proposition that injunctions may issue notwithstanding delay in clear infringement scenarios. The Court did not dispute the general propositions but found them of “doubtful” applicability in the present fact-pattern because:

  • Equitable relief was undermined by suppression/false pleading.
  • The market was described as niche/customised industrial procurement, reducing likelihood of confusion.
  • The Defendant’s long, open trading and substantial turnover made interim restraint disproportionate.

(d) Abdul Rasul Nurallah Virjee and Anr. v. Regal Footwear

This was also treated as not in dispute as a statement of principle, but the Court found the factual matrix here (industrial, customised products; weak confusion evidence; long concurrent presence) did not warrant interim restraint.

(e) Ramjas Foundation and Another, Pernod Richard India Pvt Ltd, and Chemco Plastic Industries Pvt Ltd

Although details of these decisions are not set out in the extracted text, the Court used them for three linked propositions:

  • Clean hands doctrine: a party making false statements or suppressing material facts is not entitled to equitable relief (Ramjas Foundation and Another).
  • Injunction is equitable even in IP matters; it remains subject to general equitable frameworks governing proprietary rights (Pernod Richard India Pvt Ltd).
  • In cases involving trade name/domain name restraint and opportunities to know of the defendant’s presence, courts weigh equity and balance of convenience heavily, particularly with concurrent user circumstances (Chemco Plastic Industries Pvt Ltd).

3.2 Legal Reasoning

(i) Characterising the alleged infringement: trade name use under Section 29(5)

A key factual and legal move in the judgment is the Court’s focus on what was actually being used “in a trade mark sense”. The Court recorded that the mark was not affixed/imprinted on customised products; invoices did not describe products using “MINCO INDIA”. Therefore, the dispute crystallised as the Defendant’s use of “MINCO” in its trade name/domain identity.

The Court then set out the statutory structure: Section 28 (rights of registered proprietor), Section 29 (infringement) including Section 29(5) (infringement by using the registered mark as trade name or part of trade name), and the Act’s mechanisms for lawful third-party use via assignment or registered user provisions.

(ii) Corporate personality and the “fraud” allegation about internal resolutions

The Plaintiff argued that the 2012 No Objection/consent enabling the Defendant’s name change was fraudulent because it was signed by Raghvendra (who was involved in both companies).

The Court rejected this prima facie, stressing company separateness: equating the company with a single director (or treating an internal corporate act as “fraud” solely because a director signed) ignores that a company acts through its board and resolutions. The Plaintiff did not, at the interim stage, show that the 2012 board process was unilateral or lacked consent of other directors. The Defendant’s name change resolution also occurred at an EGM with other directors.

(iii) Suppression and false pleaded “date of knowledge” as an equity-killer

The fulcrum of denial of interim relief is the Court’s finding that the plaint created a misleading picture: it suggested the Defendant was an unrelated third party and that knowledge of its activities arose only in 2024.

On the Court’s reading of the record (including the resignation letter of 15 December 2015 addressed to “Minco (India) Flow Elements Pvt Ltd” and a 7 March 2020 communication acknowledging intertwining and shared premises), the Plaintiff had knowledge at least by 2015, and prima facie since 2012.

The Court held that while “delay per se” may not always defeat infringement claims, it cannot justify incorrect statements on oath. Because interim injunction is discretionary, suppression and falsehood undermined the Plaintiff’s entitlement irrespective of the merits of registered rights in the abstract.

(iv) Balance of convenience: long open user and built-up business

The Court weighed the Defendant’s long, open use of “MINCO” (since 2012) and significant turnover. Against this, the Plaintiff’s delayed approach and misleading pleadings made interim restraint inequitable. The reasoning closely tracks the Power Control Appliances conception of acquiescence: it is unjust to permit a rights-holder to stand by while another builds an “important trade” and then seek to stop it abruptly.

(v) Confusion and passing off: niche market and “classical trinity” not satisfied

The Court treated the “confusion” evidence (the 14 February 2024 email) as weak/doubtful in context, noting that the Plaintiff’s response email itself used a GICON-linked email address and suggested the Plaintiff supplied a replacement, consistent with the Plaintiff’s own rejoinder plea that it often “salvaged” issues arising from Defendant’s products.

On passing off, the Court expressly invoked the need for cumulative satisfaction of the classical trinity: (a) goodwill, (b) misrepresentation, and (c) damage. While goodwill in “MINCO INDIA” was asserted, the Court found no prima facie showing of misrepresentation or damage, especially given the parties’ long coexistence in similar lines and the industrial/customised procurement context.

3.3 Impact

  • Pleading discipline in IP injunctions: The decision underscores that plaintiffs in trademark matters must plead candidly, especially on knowledge, history of coexistence, and any internal consents/resolutions. A registered right does not immunise a plaintiff from adverse equity where the court finds a misleading narrative.
  • Section 29(5) claims still hinge on equity at interim stage: Even when infringement is framed as trade-name use under Section 29(5), interim restraint is not automatic; courts will still apply clean-hands, acquiescence, and balance of convenience.
  • Industrial/niche markets and confusion analysis: The Court’s emphasis on customised products and discerning industrial buyers suggests that in B2B niche markets, a plaintiff may face a higher factual burden to show actionable confusion—particularly where long coexistence has occurred.
  • Corporate separateness in “family/business group” conflicts: The judgment signals that courts will resist attempts to collapse corporate acts into personal disputes; board/EGM resolutions will be treated as corporate conduct unless convincingly impeached.

4. Complex Concepts Simplified

  • Section 29(5) (Trade Marks Act, 1999): If you use someone else’s registered trademark as (or as part of) your business name/trade name for the same goods/services, that can be “infringement” even if the mark is not printed on the product.
  • Acquiescence vs Delay: “Delay” is simply waiting. “Acquiescence” is a stronger idea: knowingly allowing the other side to build its business, spending time and money, in a way that makes it unfair to later stop them suddenly.
  • Clean hands / Equity: Interim injunctions are discretionary. If a party suppresses important facts or makes false statements, the court may refuse urgent relief even if the party has arguable legal rights.
  • Passing off and the classical trinity: To prove passing off, the plaintiff generally must show: (i) goodwill in the market, (ii) the defendant’s misrepresentation leading the public to believe the defendant’s goods are the plaintiff’s, and (iii) resulting damage to the plaintiff’s goodwill.
  • Company as a separate legal person: A company is legally distinct from its directors/shareholders. Corporate decisions (like board resolutions) are treated as the company’s acts, not merely one director’s personal acts—unless the process is properly impeached.

5. Conclusion

The Bombay High Court’s refusal of interim injunction in MINCO INDIA PRIVATE LIMITED v. MINCO INDIA FLOW ELEMENTS PRIVATE LIMITED turns on a clear message: interim trademark relief is not granted on registered rights alone. Where a plaintiff pleads an implausible “date of knowledge”, suppresses material coexistence facts, and effectively stands by for years while the defendant builds a substantial business, the court may deny injunction on equity, acquiescence, and balance of convenience.

The decision is also a practical guide for Section 29(5) trade-name disputes: plaintiffs must plead the full factual matrix (including historical consents, shared directors/premises, and knowledge timelines), and must support confusion/passing off with more than isolated or ambiguous incidents—especially in niche B2B markets.
