Delhi District Court Clarifies that Subsequent Alleged Infringing Products Must Be Addressed in Execution, Not Through a Fresh Suit

Posted On - 10 July, 2026 • By - King Stubb & Kasiva

In Kent RO Systems Ltd. v. A N Polymers Pvt. Ltd., a District Court in New Delhi addressed whether a fresh design infringement suit was maintainable when the Plaintiff had already secured an injunction decree against the same Defendant for the same registered design. The judgment clarifies the boundaries between fresh litigation and execution proceedings under the Code of Civil Procedure, 1908.

Summary

In Kent RO Systems Ltd. v. A N Polymers Pvt. Ltd., CS No. 39 of 2019, the District Court, Patiala House Courts, New Delhi held that a fresh design infringement suit was not maintainable where the Plaintiff had already obtained an injunction decree against the Defendant restraining infringement of the same registered design.

The Court held that merely marketing the product complained of under a different name did not create a fresh cause of action. It further held that any subsequent violation of the injunction decree must be addressed through execution proceedings under Section 47 and Order XXI Rule 32 of the Code of Civil Procedure, 1908, and not by instituting a fresh suit.

Accordingly, the suit was dismissed as being barred by res judicata read with Section 47 CPC.

Facts of the Case

Plaintiff’s Allegations

The Plaintiff, Kent RO Systems Ltd., instituted a suit seeking permanent injunction, delivery up of infringing articles, rendition of accounts and other consequential reliefs against A N Polymers Pvt. Ltd. alleging infringement of its registered Design No. 219309 in respect of water purifiers.

The Plaintiff alleged that the Defendant was manufacturing and selling water purifiers under the mark “AQUA LIV”, whose shape deceptively resembled the Plaintiff’s “KENT GRAND+” water purifier, thereby infringing the registered design.

Defendant’s Preliminary Objection

The Defendant opposed the suit and raised a preliminary objection to its maintainability. It contended that the Plaintiff had previously instituted CS (Comm.) No. 900/2016 before the Delhi High Court against the same Defendant involving infringement of the very same registered design.

The Delhi High Court had granted a permanent injunction restraining the Defendant from dealing in products infringing Design No. 219309 and had subsequently passed the final decree in respect of the remaining reliefs. According to the Defendant, the present suit was barred by the principles of res judicata and constituted an abuse of the judicial process.

Plaintiff’s Response to the Objection

The Plaintiff argued that the earlier proceedings related to a different product sold under the name “AQUA GRAND PLUS+”, whereas the present suit concerned a product marketed as “AQUA LIV”. It further contended that:

  • The earlier judgment was delivered after institution of the present suit.
  • The parties were not identical in both proceedings.
  • The reliefs of rendition of accounts and delivery up continued to survive independently.

Issue Before the Court

Whether a fresh suit alleging infringement of the same registered design was maintainable despite an earlier decree permanently restraining the Defendant from infringing the Plaintiff’s registered design, or whether such suit was barred by res judicata and Section 47 of the Code of Civil Procedure.

Findings of the Court

No Fresh Cause of Action from a Different Product Name

The Court held that the substance of both proceedings was identical, namely, infringement of the Plaintiff’s registered Design No. 219309. It observed that the earlier decree passed by the Delhi High Court restrained the Defendant and all persons acting on its behalf from dealing in any product infringing the Plaintiff’s registered design.

Consequently, merely alleging that the Defendant marketed the product under the name “AQUA LIV” instead of “AQUA GRAND PLUS+” did not give rise to a fresh cause of action where the allegation continued to relate to infringement of the same registered design. The distinction sought to be drawn by the Plaintiff between the two product names was held to be artificial and incapable of creating a new legal dispute.

Identity of Parties Satisfied

The Court rejected the Plaintiff’s contention that the parties in the two proceedings were different. It observed that the earlier injunction extended not only to the Defendant but also to its distributors, dealers, stockists, retailers, servants, agents and all persons claiming through or under it.

Since the second Defendant in the present suit was admittedly a trader of the first Defendant, the requirement of identity of parties under Section 11 CPC stood satisfied.

Applicability of Res Judicata Despite Later Decree

The Court further rejected the argument that res judicata was inapplicable because the earlier decree had been passed after institution of the present suit. Referring to Explanation I to Section 11 CPC, it held that a “former suit” means a suit decided prior to the suit under consideration, irrespective of the date on which it was instituted.

Accordingly, once the earlier suit had been finally decided before adjudication of the present proceedings, the statutory bar applied.

Proper Remedy: Execution Proceedings, Not a Fresh Suit

The Court also held that the Plaintiff’s proper remedy was to seek enforcement of the earlier injunction through execution proceedings. Under Section 47 CPC, all questions relating to execution, discharge or satisfaction of the decree must be determined by the executing court and cannot form the subject matter of a separate suit.

The Court observed that the executing court possesses sufficient powers under Order XXI Rule 32 CPC to enforce injunction decrees, including attachment and sale of property where necessary. Permitting successive suits each time the Defendant adopted a different product name would render injunction decrees ineffective and encourage endless litigation.

Held

The District Court held that the present suit was barred by the principles of res judicata read with Section 47 of the Code of Civil Procedure. It held that the Plaintiff’s remedy lay in execution of the earlier injunction decree and not by instituting a fresh infringement suit based upon the same registered design merely because the Defendant marketed the product complained of under a different name.

The preliminary issue was therefore decided in favour of the Defendant, and the suit was held to be not maintainable.

Conclusion

The judgment reinforces that a permanent injunction restraining infringement of a registered design cannot be circumvented by simply changing the name under which the product complained of is marketed.

Once a competent court has adjudicated the issue and granted a comprehensive injunction, subsequent allegations concerning continued infringement of the same registered design must ordinarily be addressed through execution proceedings under Section 47 and Order XXI Rule 32 CPC rather than through fresh litigation. The decision underscores the following principles:

  • Finality of litigation — preventing re-agitation of issues already decided.
  • Effective enforcement of injunction decrees — channelling violations to the executing court.
  • Prevention of multiplicity of proceedings — applying res judicata in a practical and purposive manner.
