This dispute over the cough syrup mark NOKUF is one such case: a story where 25 years of active use by one party collides with the prior claim of another that barely surfaced for five years before going quiet.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Mohsin Dehlvi (&#8220;Dehlvi&#8221;), through Dehlvi Remedies Pvt Ltd (&#8220;Dehlvi Remedies&#8221;), claimed use of the NOKUF mark from as early as 1994, applied for its registration in June 1996, and obtained registration eventually with effect from that date. Sana Herbals Private Limited (&#8220;Sana Herbals&#8221;) was incorporated in October 1997, initially as a licensed manufacturer for Dehlvi Remedies under a Manufacturing Agreement dated November 1997. Sana Herbals later claimed that a September 1999 Assignment Deed transferred all rights in the NOKUF mark to it. Dehlvi Remedies denied executing the Deed.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">A fire destroyed Dehlvi Remedies&#8217; factory in 2003. The company was struck off the Register of Companies in 2007 and restored only in 2019, following which Dehlvi Remedies&#8217; pending registration application was revived and the NOKUF mark registered in its favour in September 2020. In the intervening decades, Sana Herbals had used the mark continuously, obtained registration of NOKUFSYRUP (with effect from May 2015), and built up what it described as substantial goodwill in the NOKUF brand.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">When Dehlvi signalled an intention to re-enter the market under NOKUF \/ KufNo Syrup in 2024, Sana Herbals filed a suit as a <em>quia timet<\/em> action before the Commercial Court, Tis Hazari. The Commercial Court declined interim injunction in December 2024. Sana Herbals appealed to the Delhi High Court.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Questions Before the Court<\/h3>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\">\n<li class=\"whitespace-normal break-words pl-2\">Whether, given Dehlvi Remedies&#8217; registered and prior-user claim, an infringement action was maintainable by Sana Herbals<\/li>\n<li class=\"whitespace-normal break-words pl-2\">Whether the Assignment Deed dated 19 September 1999 validly transferred rights in the NOKUF mark to Sana Herbals under the Trade and Merchandise Marks Act, 1958<\/li>\n<li class=\"whitespace-normal break-words pl-2\">Whether non-use of the NOKUF mark by the respondents between 1999 and 2024 amounted to abandonment, entitling Sana Herbals to passing off injunction<\/li>\n<li class=\"whitespace-normal break-words pl-2\">Whether Sana Herbals could establish the goodwill element required for a passing off action, given the respondents&#8217; prior use<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"><strong>Sana Herbals&#8217; Arguments<\/strong><\/h2>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\">\n<li class=\"whitespace-normal break-words pl-2\">As the registered proprietor of NOKUFSYRUP and continuous user of NOKUF since 1999, Sana Herbals had built up extensive, uncontested goodwill in the mark over 25 years<\/li>\n<li class=\"whitespace-normal break-words pl-2\">Dehlvi Remedies had not used the NOKUF mark from 1999 onwards.

Applying <em>S. Syed Mohideen v. P. Sulochana Bai<\/em> (2016) 2 SCC 683 and its own recent ruling in <em>Vaidya Rishi India Health (P) Ltd v. Suresh Dutt Parashar<\/em> (2025 SCC OnLine Del 6147), the Court held that <span style=\"text-decoration: underline;\"><strong>Section 28(3) of the Trade Marks Act bars infringement suits between two registered proprietors, though a passing off action under Section 27(2) remains available.<\/strong><\/span><\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Sana Herbals placed considerable reliance on <em>Neon Laboratories<\/em>, wherein it was held that a prior user in the market can resist a registered proprietor who remained dormant. The Court, however, found that Neon Laboratories actually operated against Sana Herbals. The Supreme Court&#8217;s ruling in that case was explicitly premised on situations where the defendant&#8217;s user post-dated the plaintiff&#8217;s user. Here, Dehlvi Remedies&#8217; user of NOKUF ran from 1994, before Sana Herbals was incorporated. The Court held that the situation was, in the Supreme Court&#8217;s own words, &#8220;unassailably favourable&#8221; to Dehlvi Remedies.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The Court further scrutinised the 1999 Assignment Deed and found it prima facie unenforceable. Since the Deed predated the Trade Marks Act, 1999 (which came into force in 2003), its validity fell to be tested under Section 38(1) of the 1958 Act,\u00a0which, unlike Section 39 of the current Act, required that goodwill accompany any trademark assignment. The Deed transferred only the right to use the mark and made no reference to goodwill. The Court held that whether goodwill could be read in from surrounding circumstances was, at best, a triable issue and not a basis for interim relief.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">Sana Herbals argued that 25 years of non-use by Dehlvi Remedies amounted to abandonment, entitling it to injunction. The Court disagreed and restated the foundational rule that, in a passing off action, goodwill must be established <strong>prior to the defendant&#8217;s adoption of the mark<\/strong>. Since Dehlvi Remedies used NOKUF from 1994 and Sana Herbals did not exist until 1997, this threshold was impossible to meet.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The Court also firmly held that non-use, with intent to abandon, is a ground for removing a registered mark under Section 47,\u00a0a remedy that involves factual inquiry in dedicated proceedings, not at the interim injunction stage. Abandonment cannot be deployed as a sword in a passing off suit.<\/p>\n<h3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\">Findings<\/h3>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">In view of the observations and the arguments presented by both parties, the Delhi High Court held that:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul class=\"[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\">\n<li class=\"whitespace-normal break-words pl-2\">No infringement claim could lie against Dehlvi Remedies, which holds a subsisting registration of the NOKUF mark, in accordance with the Trade Marks Act, 1999<\/li>\n<li class=\"whitespace-normal break-words pl-2\">The Assignment Deed dated 19 September 1999 was prima facie unenforceable at the interim stage, as it did not transfer goodwill alongside trademark rights as mandated by Section 38(1) of the Trade and Merchandise Marks Act, 1958<\/li>\n<li class=\"whitespace-normal break-words pl-2\">Sana Herbals could not establish the goodwill element required for a passing off action, since Dehlvi Remedies had commenced use of the NOKUF mark in 1994, before Sana Herbals was incorporated<\/li>\n<li class=\"whitespace-normal break-words pl-2\">Non-use of the NOKUF mark by Dehlvi Remedies did not give rise to any passing off right in favour of Sana Herbals; the appropriate forum to raise abandonment would be through Section 47 rectification proceedings<\/li>\n<li class=\"whitespace-normal break-words pl-2\">The appeal was dismissed with no order as to costs, and the Commercial Court&#8217;s denial of interim injunction was upheld<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"><strong>Case Citation:<\/strong> <em>Sana Herbals Private Limited v.
