Madras High Court set aside the dismissal of opposition to registration of the mark ‘Nandini’ in Class 3 for agarbattis, holding that identical phonetic identity and stylisation create deceptive similarity and likelihood of confusion with the appellant’s well-known ‘Nandini’ mark for dairy products, distinguishing it from the Supreme Court’s Nandhini Deluxe judgment due to absence of differentiating elements like suffix or different get-up.

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.

The Delhi High Court held that the Commercial Courts (Amendment) Act, 2018, reducing the specified value for commercial disputes to Rs. 3 lakhs, applies prospectively only to suits filed on or after May 3, 2018, and does not permit retrospective transfers of pre-2018 suits under Section 15 of the 2015 Act, preserving vested rights and avoiding administrative burdens.

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.

This judgment settles that in trademark disputes involving registered marks, no statutory infringement action lies against another registered proprietor under Section 28(3) of the Trade Marks Act, 1999, but passing off remains actionable under common law via Section 27(2), provided the plaintiff proves prior goodwill predating the defendant’s use, misrepresentation, and damage.
