Delhi High Court allows appeal against trial court’s interim injunction in trademark suit over “ATHERMAL,” holding appellant’s prima facie prior use since 1990 through predecessor superior to respondents’ 2017 registration and 2003 claim, distinguishes approbate and reprobate as inapplicable to primary mark, sets aside order.

Delhi High Court dismisses Canva’s appeal against interim injunction for infringing RxPrism’s patent on interactive content system; upholds single judge’s prima facie findings on layered architecture, configurability, and doctrine of equivalents; emphasizes claim-centric analysis for infringement and validity, rejecting product-to-product comparisons and unsubstantiated prior art challenges;

This judgment clarifies that under Order XI Rule 1(10) CPC, as applicable to commercial suits, “reasonable cause” for non-disclosure of documents with the written statement demands a genuine, specific explanation, with a lower proof threshold than “good cause” but mandating demonstration that documents were not in the defendant’s power, possession, custody, or control at filing; mere delay or post-appeal discovery without prior diligence does not suffice, reinforcing the Commercial Courts Act’s intent for vigilant, time-bound litigation over procedural leniency in ordinary suits.

High Court of Delhi holds that writ petitions challenging pre-abolition orders of the Intellectual Property Appellate Board (IPAB) on trademark matters are to be heard by a Single Judge of the Intellectual Property Division (IPD), as per IPD Rules, 2021, unless falling under specific Division Bench exceptions in Delhi High Court Rules; rejects mandatory Division Bench listing, treating such petitions as original IPD proceedings for efficient adjudication post-IPAB dissolution.

This judgment settles several critical points in patent litigation, particularly for biologics in quia timet scenarios, affirming that product-to-claim mapping under Rule 3(A)(ix) of the Delhi High Court Patent Suits Rules cannot be entirely dispensed with, even in anticipatory actions; the phrase “to the extent possible” allows flexibility but demands maximum feasible effort, and collateral evidence alone may not suffice for prima facie infringement without raising triable issues.
