Battle of the Kents: Delhi HC Bars RO Giant from Fan Foray Under Shared Trademark

In a high-stakes trademark tussle, the Delhi High Court Division Bench of Justice Navin Chawla and Justice Madhu Jain on March 11, 2026, dismissed appeals by Kent RO Systems Limited and others, upholding a single judge's order. The ruling permanently restrains Kent RO from manufacturing or selling fans under the 'KENT' mark during the pendency of suits, while allowing rival Kent Cables Private Limited to continue. This decision pivots on prior use, acquiescence, and the limits of trademark expansion in overlapping markets.

Origins in Wires and Water: A Timeline of Twin Adoptions

The rivalry traces back decades. Kent Cables claims adoption of 'KENT' in 1984 for insulated wires, cables, switches, and electrical components, securing its first Class 9 registration in 1986. By 1998, it applied for 'KENT' in Class 11 for fans on a "proposed to be used" basis. Evidence shows Kent Cables selling fans under the mark since at least 2009, backed by invoices, government approvals, and e-commerce listings.

Kent RO entered later, adopting 'KENT' in 1988 for oil meters (registered 1994), expanding to RO water purifiers in 1999, air purifiers in 2006, and other home appliances. It boasts massive goodwill—Rs. 7,654 crores in sales (2007-2021) and Rs. 1,106 crores in marketing—but lacks registration or prior use for fans, despite Class 11 marks specifically for water purifiers.

Tensions boiled in 2022. Kent RO invested Rs. 155 crores in fans and sought to block Kent Cables' expansion into kitchen appliances and fans via CS(COMM) 508/2022. Kent Cables countersued (CS(COMM) 596/2022), alleging reverse confusion. Cross-injunction applications led to the single judge's May 2023 order favoring Kent Cables, sparking these appeals (FAOs(OS)(Comm) 141/2023 & 142/2023).

RO's Push: Well-Known Mark Meets Home Appliances

Kent RO, represented by Sr. Adv. Chander M. Lall, argued prior user status for home appliances since 1999, with fans as "allied and cognate" to air purifiers and water systems under Class 11. Citing registrations like 'KENT MINERAL RO' (2007) and 'KENT' declared well-known (2014), they claimed infringement under Section 29(2)(a) Trade Marks Act, 1999, due to identical marks, shared trade channels, and actual confusion on e-platforms like Amazon. They dismissed Kent Cables' fan use as post-2011 cease-and-desist and mala fide, urging no acquiescence given opposition in 2007. Precedents like Toyota Jidosha and Intex Technologies underscored transitivity of goodwill.

Cables' Counter: First Adopter Digs In with Evidence

Sr. Adv. Jayant Mehta for Kent Cables stressed 1984 prior adoption, 1986 registration predating Kent RO's, and documented fan sales since 2009 (invoices, BEE approvals, hoardings). Fans were a "natural progression" from cables, not piggybacking RO's purifiers. They invoked Section 34's vested rights for prior continuous use, denying cognate goods similarity—water purifiers ≠ fans despite Class 11. Kent RO's decade-long dormancy post-2011 notice screamed acquiescence, tilting balance of convenience their way. Cases like S. Syed Mohideen and Neon Laboratories reinforced prior user supremacy.

Dissecting the Divide: No Cognate Leap, Acquiescence Seals It

The Bench meticulously parsed registrations: Kent RO's Class 11 marks cover purifiers explicitly, not fans. Mere class overlap doesn't imply similarity; classification aids registration, not infringement ( Vishnudas Trading , FDC Ltd. ). Kent Cables' 1998 fan application, opposed in 2007 but unmet by suit till 2022, evidenced bona fide expansion. Section 29(2)(a) failed for lack of goods similarity; Section 29(4) didn't apply sans unfair advantage.

Section 34 shielded Kent Cables' prior fan use. Kent RO acquiesced by monitoring lapses post-notice, allowing growth. Raman Kwatra distinguished cables from appliances but affirmed natural progression. Balance favored Cables' established fan business over RO's unlaunched venture ( Wander Ltd. limits appellate interference).

Court's Cutting Quotes

  • On Prior Adoption : "The adoption of the mark „KENT‟ by the respondents [Cables], therefore, cannot be said to be mala fide . In fact, it is the respondents who would be the first adopters of the said mark, albeit for a different product."
  • Acquiescence Bite : "Having opposed the registration and also given a cease and desist notice... the appellants could not have kept quiet and allowed the respondents to grow by continuing the use of the mark."
  • Injunction Logic : "Kent Cables has made out a case of prior user and passing off by prima facie establishing its reputation and goodwill, confusion likely to be caused... balance of convenience lies in favour of Kent Cables."

Verdict Echoes: Fans Stay with Cables, RO Redirects

Appeals dismissed; status quo ante upheld—no interim relief for Kent RO, injunction against its fans persists. Prima facie observations bind no final trial. Practically, it cautions expanders: secure specific registrations, act swiftly on rivals. For Kent RO, a pivot from fans amid Rs. 155 crore investment; for Cables, validated 15+ year fan foothold. This reinforces common law prior use trumping registration where goods diverge, shaping India's crowded appliance branding wars.
