John Cockerill Hamon Vs Hamon Cooling Systems :06.07.2026 : Interim Application No. 345 of 2026 in Commercial IP Suit No. 7 of 2026 : BombHC: Mr. Justice Arif S. Doctor, H.J.
The court considered a dispute concerning the infringement and passing off of the trademark "HAMON". The case arose from allegations that the defendant, after separating from the global Hamon Group, unauthorizedly continued to use the trademark "HAMON" in its corporate name, domain name, and trading style beyond the limited, temporary brand usage right granted to complete pending projects. The principal question before the Court was whether a derivative user whose adoption of a mark was traceably permissive could claim independent proprietary or statutory prior user rights against the lawful successor-in-title of the trademark.
After examining the material on record and the submissions of the parties court observed that the defendant had explicitly admitted that its initial use of the mark was permissive and had further filed subsequent trademark applications on a "proposed to be used" basis. The Court held that a permissive user or licensee cannot assert independent proprietary rights or a defense of prior use adverse to the registered proprietor, emphasizing that the goodwill generated by such derivative use entirely inures to the benefit of the principal trademark owner.
Accordingly, the Court allowed the matter and directed that the defendants be temporarily restrained from using the mark "HAMON" or any deceptively similar mark in respect of their goods, services, corporate name, and domain names pending the final disposal of the suit.

Trademark Assignment Effective Inter Partes Before Register Recordal
Introduction
The preservation of statutory boundaries governing trademark assignments and permissive use remains crucial to safeguarding corporate goodwill in transnational commercial transactions. When international conglomerates undergo global bankruptcy reorganization, the distribution of their intellectual property assets often creates friction with regional subsidiaries or joint venture partners who previously operated under authorized commercial lenses. The judgment of the Ordinary Original Civil Jurisdiction of the Bombay High Court in the "HAMON" trademark dispute elegantly dissects this conflict.
Factual and Procedural Background
The foundational trademark "HAMON" was adopted in the year 1963 by a Belgian entity named Engetra S.A. for cooling systems, air conditioning apparatus, and related engineering products, subsequently securing statutory registrations in India under Classes 7 and 11 in 1988. In September 1999, Engetra S.A. executed a Deed of Assignment transferring its total statutory rights and existing goodwill in India to Hamon & CIE (International) S.A., a company that went on to acquire a substantial corporate presence in India by taking over a domestic engineering firm. This domestic firm underwent several corporate name transformations due to changing joint venture partnerships, evolving into Hamon Shriram Cottrell Private Limited, and ultimately, following an increase in parent shareholding to 99.16% around 2019–2020, becoming Hamon Cooling Systems Private Limited the first defendant in the current litigation.
In 2022, the global parent company faced severe financial distress, triggering judicial reorganization proceedings in Belgium that rapidly converted into structural bankruptcy. Court-appointed bankruptcy trustees took charge of the liquidation assets. During these proceedings, CMI France, a subsidiary belonging to the John Cockerill Group, successfully bid to acquire the entire global portfolio of "HAMON" brands, trade names, patents, and intellectual property assets. Following the required authorization from the specialized commercial tribunals in Europe, a definitive Transfer Agreement was executed on July 25, 2022, effectively conveying the worldwide intellectual property rights and associated goodwill to the plaintiff, John Cockerill Hamon SA.
Crucially, because the Indian corporate infrastructure of the first defendant was not fully acquired by the plaintiff's corporate group, the plaintiff paid an extra contractual consideration of €500,000 to the bankruptcy trustees to accommodate a temporary arrangement known as the "Brand Usage Right". This temporary right allowed non-acquired entities to utilize the "HAMON" branding for the sole, restrictive purpose of fulfilling their active, ongoing engineering contracts. Shortly thereafter, in September 2022, a Share Sale Agreement completely severed the first defendant from the parent group by transferring its total equity stake to a domestic individual buyer. This agreement expressly bound the new management to finish only the specific projects listed within its schedules under the temporary brand canopy.
Instead of phasing out the brand name, the first defendant filed domestic trademark applications for the marks "HAMON COOLING" and "HCS HAMON COOLING" on a "proposed to be used" basis. Despite receiving a statutory examination report citing the plaintiff's prior registrations as conflicting marks, and experiencing an administrative rejection of its primary application, the first defendant continued to aggressively trade, tender, and communicate using the "HAMON" brand name and its associated domain. After discovering that the first defendant was using the global group’s historical technical credentials to secure large-scale public sector projects, and observing actual confusion among major trade clients, the plaintiff issued a formal cease and desist notice in April 2024. When the first defendant ignored the notice and continued its extensive usage, the plaintiff moved the Bombay High Court by filing a commercial intellectual property suit coupled with the present interim application.
Dispute Before the Court
The primary legal and factual grid presented for adjudication was whether the plaintiff possessed a valid legal title to sustain an action for trademark infringement and passing off, and whether a former corporate subsidiary could independently assert defensive rights over a mark it had continuously utilized under an institutional corporate umbrella.
The plaintiff argued that it had completely stepped into the corporate shoes of the prior registered proprietor through a valid chain of assignment from the Belgian bankruptcy trustees. They asserted that the first defendant’s right was purely derivative and temporary, specifically limited by the global Transfer Agreement to finishing active projects. The plaintiff contended that since the first defendant admitted that its historical use since 1999 was based on express or implied consent, it was legally barred from setting up a defense of independent prior use. Furthermore, they pointed out that the first defendant's recent filing of trademark applications on a "proposed to be used" basis was an absolute admission that it lacked any prior independent proprietary rights.
The first defendant raised heavy technical objections against the validity of the trademark assignment, pointing out that the plaintiff's name was not yet recorded as the subsequent proprietor across all matching entries in the Indian Trade Marks Register. They contended that the underlying Transfer Agreement failed to explicitly itemize the Indian registration numbers and was unstamped and legally incomplete due to non-advertisement under Section 42 of the Trade Marks Act. On the merits, the first defendant asserted that it had built substantial independent local goodwill in India over two decades, valuing its active public sector infrastructure projects at over Rs. 450 crores. They claimed protection under statutory defenses of continuous prior use, long-standing acquiescence, and explicit consent, stating that an interim injunction would paralyze critical public works and severely harm hundreds of domestic employees.
Reasoning and Analysis of the Court
The Court focused its initial analysis on the procedural validity of the plaintiff’s legal title. It observed that the comprehensive language used in the global Transfer Agreement left no doubt that the complete portfolio of brands, trade names, and worldwide intellectual property assets owned by the parent company was validly transferred to the plaintiff. The Court rejected the first defendant's argument that the pending status of recordal applications before the Trade Marks Registry barred an action for infringement. It reaffirmed the established legal position that a trademark assignment is completely effective inter partes from the moment the written instrument is executed, and its enforceability in a court of law does not depend on the administrative completion of the register entries. Relying upon recognized judicial precedents, the Court noted that a pending application for recording an assignment does not block the assignee from seeking emergency interlocutory reliefs against open infringement.
Addressing the first defendant’s defense under Section 34 of the Trade Marks Act, 1999, which protects continuous prior user rights, the Court examined the admissions made within the defense pleadings. The first defendant had repeatedly stated that its long-standing usage of the mark since 1999 was supported by the express or implied consent of the original parent proprietor. The Court ruled that the defenses of independent prior use and permissive use are fundamentally inconsistent and mutually destructive. Statutory protection for a prior user requires an independent, adverse adoption of the mark. A party that traces its adoption to the consent or license of a registered owner directly acknowledges that owner's superior title and cannot later claim an independent proprietary right.
The Court also highlighted the concept of derivative goodwill. It observed that any commercial goodwill or brand reputation developed by a subsidiary or licensee using a mark with the owner's consent automatically inures to the sole benefit of the principal licensor. It does not create any permanent, independent property rights for the user. The Court found the first defendant's recent applications to register the marks on a "proposed to be used" basis particularly telling. It noted that a corporation claiming to have used a mark independently for a quarter of a century does not formally declare to a statutory authority that the mark is merely "proposed to be used". This behavior, combined with the defendant's attempt to use the plaintiff’s global historical credentials to secure public tenders, demonstrated a lack of bona fides and an attempt to trade on a corporate lineage it no longer possessed.
Finally, the Court dismissed the objections concerning Section 42 of the Trade Marks Act and the alleged lack of public advertisement. It found that because the global transfer conveyed the intellectual property assets along with their structural corporate goodwill, the statutory requirements for advertising an assignment made *without goodwill* did not apply. The defense of acquiescence was also rejected because the first defendant failed to show any positive, encouraging act by the plaintiff or its predecessor that would justify its continued use after its temporary permission expired. The plaintiff's prompt issuance of a cease-and-desist notice within two years of the global bankruptcy purchase further defeated any claim of unreasonable delay or implied consent.
Final Decision of the Court
The High Court of Delhi concluded that the plaintiff had established a robust prima facie case of trademark infringement and passing off, and that the balance of convenience heavily favored protecting the rights of the lawful trademark owner. The Court observed that allowing a former permitted user to continue using the mark after its authorization expired would cause irreparable harm to the plaintiff's global brand reputation and create severe confusion in public tenders. The Court explicitly noted that protecting the public and public sector undertakings from misleading corporate representations regarding business lineage was a matter of significant public interest.Accordingly, the Court allowed the interim application in terms of the primary injunction prayers, temporarily restraining the defendants, their directors, and agents from using the mark "HAMON", "HAMON COOLING", "HCS HAMON COOLING", or any deceptively similar variation as a trademark, corporate name, domain name, or trading style.
Point of Law Settled
The judgment clarifies and solidifies two vital areas of intellectual property jurisprudence in India:
The Exclusivity of Permissive User vs. Prior User Defense: A party that acknowledges its trademark use began with the express or implied consent of a registered proprietor is legally considered a permissive user or licensee. Such a party cannot later claim the defense of an independent "prior user" under Section 34 of the Trade Marks Act, 1999, as these two legal positions are structurally incompatible.
Inter Partes Effect of Trademark Assignments:A trademark assignment is legally complete and enforceable between the parties upon the proper execution of the written assignment deed. The assignee's right to file an action for infringement and seek interim relief is not blocked or suspended by administrative delays in updating its name on the official Trade Marks Register.
Inurement of Goodwill: All commercial goodwill and market reputation generated by a corporate subsidiary or licensee through the authorized use of a trademark belongs entirely to the principal trademark owner or its lawful successors-in-title, and does not create any independent proprietary rights for the user.

### Headnote of the Judgment:
**Case Title:** *John Cockerill Hamon SA v. Hamon Cooling Systems Private Limited & Anr.*
**Court:** High Court of Judicature at Bombay (Ordinary Original Civil Jurisdiction)
**Procedural Detail:** Interim Application under Order XXXIX Rules 1 and 2 in a Commercial IP Suit seeking temporary injunction for trademark infringement and passing off.
**Final Decision:** Interim Application Allowed.
The plaintiff, as the global assignee of the "HAMON" trademark portfolio from a bankrupt Belgian parent entity, sought an injunction against the first defendant, a former domestic subsidiary. After its corporate separation, the defendant continued to use the mark "HAMON" in its corporate name, trading style, and public tenders beyond a temporary project-completion allowance. The High Court allowed the injunction, ruling that a trademark assignment is complete inter partes upon execution and its enforcement is not barred by pending register updates. Furthermore, the Court held that because the defendant admitted its historical use was permissive, it was legally barred from claiming an independent "prior user" defense under Section 34, as all derivative goodwill inures solely to the trademark owner.
