Case Title: Panasonic Holdings Corporation Vs Siddharth Vij
Case Number: C.O. (COMM.IPD-TM) 171/2025
Date of Judgment: 05 June 2026
Neutral Citation: 2026:DHC:5074
High Court: Delhi High Court
Hon'ble Judge: Tushar Rao Gedela
In a trademark rectification dispute, the Delhi High Court allowed petitions filed by Panasonic Holdings Corporation and its affiliate seeking cancellation of the registered word mark “PONTA” and device mark registered in Class 9 for electrical goods. The petitioners contended that “PONTA” was deceptively similar to their long-standing and registered trademark “PENTA”, which has been in use since 1989 and enjoys substantial goodwill in the market for electrical switches, sockets and related products.
Justice Tushar Rao Gedela observed that the marks “PENTA” and “PONTA” were visually, structurally and phonetically similar, with the mere substitution of the letter “E” by “O” being insufficient to distinguish the two marks. The Court noted that both parties dealt in identical goods through common trade channels and that the respondent had failed to provide any satisfactory explanation before the Trade Marks Registry for adopting the impugned mark despite objections based on the petitioner’s prior trademark. The Court also rejected the respondent’s subsequent explanation linking the mark to “Paonta Sahib”, holding it to be an afterthought.
Holding that the registration of “PONTA” was made without sufficient cause and was wrongly remaining on the Register, the Court exercised powers under Section 57 of the Trade Marks Act, 1999 and directed the Registrar of Trade Marks to remove and rectify both the word mark “PONTA” and the associated device mark from the Register within four weeks.

PENTA vs PONTA: When Faith Meets Fraud — Delhi High Court Cancels Trademark Registration of Deceptively Similar Mark in Electrical Products Dispute
Introduction
In the world of intellectual property law, few questions are as practically significant as this: can a trademark that differs from an established brand by just one vowel survive legal scrutiny? This case, decided by the High Court of Delhi on 5 June 2026, answers that question with a resounding no. The dispute pits one of the world's most recognised electronics corporations, Panasonic Holdings Corporation of Japan, against an individual entrepreneur who had registered the marks PONTA and its stylised device version in India for electrical goods — products that are strikingly similar to those sold under Panasonic's long-established PENTA brand.
What makes this case particularly interesting — and instructive — is not just the similarity of the marks themselves but the manner in which the defence was constructed. The respondent, when confronted with the cancellation petition, offered a story rooted in religious faith and linguistic diversity that he had never thought to mention before the Trade Marks Registry at the time of registration. The court's treatment of this afterthought defence raises important questions about the integrity of explanations offered belatedly in legal proceedings, the evidentiary value of research generated by Artificial Intelligence tools, and the standards that must be met for a mark to survive a cancellation petition under the Trade Marks Act, 1999. This is also a case that settles, with clarity, how the court applies Section 57(2) of the Trade Marks Act, 1999 when a mark has been registered despite a clear objection raised by the Trade Marks Registry's own Examination Report.
Factual and Procedural Background
Panasonic Holdings Corporation is a Japanese company incorporated in the year 1918, engaged in the manufacture, marketing and sale of electrical products across multiple business segments. It entered India in the year 1972 and subsequently expanded its operations in India through subsidiaries and associated companies, aided by liberalisation of Foreign Direct Investment policies. The second petitioner is its associated Indian entity through which the PENTA brand is operated in India.
A significant chapter in the petitioner's Indian business history occurred in 2007 when it acquired the business of the "Shah Family Group" — a well-known Indian group — along with its goodwill and trademarks, including the brand PENTA, for a consideration of Rs. 110 crores. The trademark PENTA in Class-9 (which covers electrical and electronic goods) had originally been applied for registration on 18 September 1989 by the predecessor-in-title. Since then, the petitioner has used the mark PENTA continuously and uninterruptedly for a wide range of electrical products including switches, sockets, regulators, plugs, conduit pipes, and allied goods.
The petitioner holds multiple registrations for the mark PENTA and its variants in Class-9. The original registration bearing number 516905, applied for on 18 September 1989, has been renewed and remains valid until 18 September 2026. A second registration bearing number 1054399 was applied for on 25 October 2001 and is valid until 25 October 2031. Several other registrations for variants such as PENTA PC, PENTA Urea, PENTA MODULAR, and PENTA MODULAR EXIMA were obtained in subsequent years. The products bearing the PENTA trademark are sold through a countrywide network of authorised distributors, stockists, dealers and retailers extending across states such as Maharashtra, Gujarat and Rajasthan, and are also available on major e-commerce platforms including Flipkart and Amazon. Promotional activities cover print media — both national and regional — television, websites, and social media platforms such as Facebook, YouTube, Instagram, and X (formerly Twitter). The sales turnover of the petitioner under the marks PENTA and PENTA MODULAR grew from approximately Rs. 3,26,02,33,791 in the financial year 2013-14 to Rs. 6,31,60,38,458 in the financial year 2024-25 up to November 2024.
Against this backdrop, the respondent no.1, Mr. Siddharth Vij, applied on 30 March 2019 for registration of the word mark PONTA bearing application number 4134589 in Class-9, in respect of electric sockets, electric plugs, electric switches, and multi-plugs. On the same date, he also applied for registration of a stylised device mark — the word PONTA rendered with a distinctive design element in the letter "O" — bearing application number 4885149, also in Class-9. Crucially, both applications were filed on a "proposed to be used" basis, meaning the respondent had not used either mark in commerce at the time of filing.
The Trade Marks Registry issued an Examination Report dated 21 May 2019 raising an objection under Section 11(1) of the Trade Marks Act, 1999, specifically citing the petitioner's registered marks PENTA bearing registration numbers 516905 and 1054399 as conflicting marks. The Report clearly flagged that the proposed mark PONTA was identical with or similar to the existing marks on the register in respect of identical or similar goods, thereby creating a likelihood of confusion among the public. In response to this Examination Report, the respondent filed a reply on 25 May 2019 — a reply that consisted of merely two short paragraphs — baldly asserting that the marks PENTA and PONTA are different and requesting that the objection under Section 11 be waived. No reason, explanation, or justification for the adoption of the mark was offered; no linguistic analysis, no explanation of inspiration, no story about religious faith — nothing. Despite this wholly inadequate reply, the Trade Marks Registry proceeded to register the word mark PONTA on 22 February 2021 and the device mark on 9 August 2021. The respondent also executed Memoranda of Understanding dated 10 August 2020 and 3 March 2021 licensing both marks in favour of his mother, Ms. Karishma Vig, proprietor of M/s India Electrical Industries, for manufacturing, marketing and selling electrical goods under the PONTA mark.
Aggrieved by these registrations, the petitioner filed two cancellation petitions before the High Court of Delhi — C.O.(COMM.IPD-TM) 171/2025 challenging the device mark registration no. 4885149, and C.O.(COMM.IPD-TM) 172/2025 challenging the word mark registration no. 4134589 — under Sections 47 and 57 of the Trade Marks Act, 1999. With the consent of the parties, both petitions were heard and decided together by a common judgment. The judgment was reserved on 10 April 2026 and delivered on 5 June 2026.
The Dispute
The core of the petitioner's case was straightforward: the mark PONTA is deceptively similar to the well-established registered mark PENTA, the goods are identical, the trade channels are common, and the adoption was dishonest. The petitioner emphasised that by the time the respondent entered the market in 2019-20, the PENTA brand had already clocked an annual turnover of approximately Rs. 7,88,18,59,411, making it a dominant force in the electrical products market. The petitioner also pointed to the fact that the respondent's own reply to the Examination Report was conspicuously silent on any explanation for the adoption of PONTA, yet the Trade Marks Registry still granted registration — an act the petitioner characterised as a clear procedural deficiency and error under Section 9 and Section 18 read with Section 11 of the Trade Marks Act, 1999. The petitioner sought cancellation under Sections 47 and 57 of the Act, arguing that the registration was granted without sufficient cause.
The respondent defended the registrations on multiple grounds. First and most notably, it was claimed for the very first time before the court — not before the Trade Marks Registry — that the respondent is a devout follower of the Sikh faith and was inspired to adopt the name PONTA by the sacred Gurudwara Shri Paonta Sahib. This religious faith, it was claimed, made the adoption genuine and honest, entitling the respondent to protection under Section 12 of the Trade Marks Act, which provides for registration of a mark notwithstanding a prior conflicting mark where there is honest and concurrent use. Second, the respondent argued that the word PONTA carries diverse meanings in various languages around the world, and therefore its adoption was arbitrary and bore no relation to the products manufactured. Third, the respondent claimed that by the time of the present proceedings, it had built its own goodwill under the PONTA mark, with turnover growing from Rs. 87,08,350 in the financial year 2020-21 to Rs. 3,06,56,040 in the financial year 2024-25, supported by BSI certifications and MSME registration. Finally, the respondent characterised the petitioner's action as an attempt by a large corporate entity to harass and intimidate a small business owner.
Reasoning and Analysis of the Court
The court examined the facts with considerable care, beginning by acknowledging the overwhelming documentary evidence of the petitioner's long and extensive use of the PENTA mark. The sales figures extending from FY 2013-14 to FY 2024-25, supported by a Chartered Accountant's certificate, invoices dating from 2005, brochures and price lists from 2008, newspaper advertisements from 2002, and consistent online promotional activity — all of this, considered together, led the court to conclude firmly that the petitioner had garnered substantial goodwill and immense reputation in respect of PENTA for electrical goods in Class-9.
A pivotal analytical moment in the judgment came when the court pointed to the comparative position of the two parties at the time the respondent entered the market. In FY 2019-20, when the respondent's business effectively commenced, the petitioner had already achieved a combined PENTA and PENTA MODULAR turnover of approximately Rs. 7,88,18,59,411. The court observed that this enormous and established commercial presence of the petitioner at that very point of time would, in its view, provide a clear motivation for the respondent to adopt a mark similar to PENTA — an observation that is at once pragmatic and damning.
On the critical question of the similarity between the marks, the court conducted a visual comparison. Looking at PENTA and PONTA as plain word marks, the court found the resemblance to be glaring — almost identical. The mere substitution of the letter "E" with "O" creates no meaningful distinction. Even more remarkably, the court observed that in the stylised device mark of the respondent — where the letter "O" is rendered with a distinctive design element built into it — the visual effect is such that the "O" actually appears to look like an "E" at first glance. This meant that even the artistic design choice made by the respondent, far from differentiating the mark from PENTA, paradoxically made it look even more like PENTA. The court found no dissimilarity whatsoever — the mark PONTA was held to be visually, structurally, and conceptually, if not identical, then clearly deceptively similar to PENTA.
Applying the well-established test of the unwary consumer with average intelligence and imperfect recollection — a consumer who does not sit down with both marks side by side and examine them minutely — the court held that such a consumer is likely to be confused or deceived into buying the respondent's goods believing them to be those of the petitioner. The court also noted the practical reality of who buys these products: electricians, petty contractors, and ordinary members of the public. These are not sophisticated purchasers who conduct diligent brand verification. They buy by name and by memory. Accordingly, the triple identity test — identical marks (or deceptively similar), identical goods, and identical trade channels — was held to be amply satisfied.
The court then turned to the religious inspiration defence, which it characterised in terms that are unusually candid for judicial writing. The explanation of deriving inspiration from Gurudwara Shri Paonta Sahib was described as a "brilliant and most innovative storyline" and "though seemingly attractive" was found to be "unpersuasive and unmerited." The reason is important: this explanation had never been placed before the Trade Marks Registry at the time of responding to the Examination Report on 25 May 2019. The two-paragraph reply of May 2019 said nothing about religious faith, nothing about Gurudwara Paonta Sahib, and nothing about the linguistic meaning of PONTA in foreign languages. Since the Registry never had the opportunity to consider and evaluate this story, the court held that it could not and would not accept this explanation as a reason to sustain the registration. The court went further, stating plainly that it appeared the respondent had "cooked up a story" to align with a mala fide adoption of the mark — a remarkably direct judicial assessment of the respondent's credibility.
On the linguistic diversity argument — that PONTA means various things in various languages globally — the court noted that the respondent had relied on research generated entirely by Artificial Intelligence tools, without any independent authentication or corroborative evidence of the actual existence of such words or meanings in the claimed foreign languages. The court declined to place any reliance on such unauthenticated and unverified material. This is a significant judicial statement about the limitations of AI-generated content as legal evidence, and one that practitioners and litigants would do well to heed.
The court also addressed the protection claimed under Section 12 of the Trade Marks Act, 1999, which permits registration of a mark even where a prior conflicting mark exists, provided the use is honest and concurrent. The court rejected this argument on two independent grounds. First, the adoption cannot be said to be honest given that no genuine reason was ever offered to the Trade Marks Registry despite the Registry's own specific objection. Second, there can be no concurrent use because the respondent had not used the mark at all when it applied for registration — both applications were on a "proposed to be used" basis — and by the time actual use commenced, the petitioner was already an overwhelmingly dominant commercial presence in the same market.
On the question of which provision of law would best govern the cancellation, the court drew a distinction between Sections 47 and 57 of the Trade Marks Act, 1999. Section 47(1)(a) requires proof of two conditions: that the mark was registered without bonafide intention to use it, and that there has been no bonafide use for three months before the date of application. The court found Section 47 inapplicable here because the respondent had applied on a "proposed to be used" basis (so the three-month use condition before filing is necessarily absent) and had since placed invoices showing some commercial use (making the bonafide intention issue less clear). However, Section 57(2) of the Act, which empowers the court to expunge or vary a registration where an entry has been made "without sufficient cause" or an entry "wrongly remains" on the register, was found to be squarely applicable. Since the mark PONTA was deceptively similar to the petitioner's mark PENTA, since the Registry had raised a specific objection under Section 11(1) which was not adequately answered, and since no valid justification for adoption existed, the registration was entered without sufficient cause and the respondent's mark had no lawful basis to remain on the Trade Marks Register.
The judgments cited by the petitioner in support of its case included Kamani Oil Industries Pvt. Ltd. v. Bhuwaneshwar Refineries Pvt. Ltd., 2014 SCC OnLine Bom 595; Aktiebolaget Volvo of Sweden v. Volvo Steels Ltd. of Gujarat (India), 1997 SCC OnLine Bom 578; Federal Express Corporation v. Fedex Securities Pvt. Ltd. & Ors., 2025 SCC OnLine Bom 5056; Mallcom (India) Ltd. v. Shanti Udyog Weldsafe Pvt. Ltd. & Ors., 2024 SCC OnLine Del 2751; and Mallcom (India) Ltd. & Anr. v. Rakesh Kumar & Ors., 2019 SCC OnLine 7646. These authorities were cited in the context of deceptive similarity and the legal standards for comparing competing marks, reinforcing the proposition that single-vowel differences in five-letter words used for identical goods do not create sufficient distinction to avoid confusion.
Final Decision of the Court
The court allowed both petitions and directed the Registrar of Trade Marks — respondent no. 2 — to remove and rectify the Register of Trade Marks by cancelling the word mark PONTA bearing application number 4134589, registered on 22 February 2021, and the device mark bearing application number 4885149 in Class-9, registered on 9 August 2021, both registered in the name of the respondent no.1. The Registrar was directed to carry out this exercise within four weeks from the date of receipt of the order. No costs were awarded to either party.
Points of Law Settled in the Case
This judgment makes several contributions to the development of Indian trademark law. It holds unequivocally that Section 57(2) of the Trade Marks Act, 1999 is the appropriate provision to seek cancellation of a mark that was registered "without sufficient cause" — particularly where the Trade Marks Registry had raised its own objection in the Examination Report, that objection was never adequately addressed, and yet registration was wrongly granted. The court clarifies the distinction between Section 47 and Section 57, noting that Section 47 presupposes use-related analysis which may not always apply to marks filed on a "proposed to be used" basis.
The judgment settles that explanations for the adoption of a mark, if not placed before the Trade Marks Registry at the earliest opportunity — specifically in response to the Examination Report — cannot be introduced for the first time before the court in cancellation proceedings. A party that chooses to remain silent before the Registry cannot construct a fresh narrative in litigation and expect the court to treat it as credible. This is a procedural discipline of significant importance.
The judgment is also noteworthy for its treatment of AI-generated evidence. It expressly holds that research produced through Artificial Intelligence tools, without independent authentication or corroborating material, is unauthenticated and unverified and cannot be relied upon in court proceedings. This is one of the early and clear judicial statements in Indian intellectual property law on the evidentiary limitations of AI-generated content.
On deceptive similarity, the court confirms that a single-vowel substitution in a five-letter word used for identical goods in the same class does not create any meaningful distinction. The standard of comparison is the ordinary consumer — an electrician, a petty contractor, a householder — who buys by memory, not by careful examination. The visual and phonetic proximity of PENTA and PONTA satisfies the deceptive similarity test comprehensively.
Finally, the court reaffirms that the protection of honest concurrent use under Section 12 of the Trade Marks Act, 1999 is not available to a party whose adoption cannot be characterised as honest — particularly where that party had not used the mark at all at the time of registration, and where the mark is deceptively similar to a massively popular prior-registered mark in the same field.

Head Note
Facts: Panasonic Holdings Corporation, owner of the well-established trademark PENTA registered in Class-9 since 1989 for electrical goods with annual turnover exceeding Rs. 788 crore by FY 2019-20, filed cancellation petitions against the registered word mark PONTA (registration no. 4134589, registered 22 February 2021) and device mark PONTA (registration no. 4885149, registered 9 August 2021) in Class-9, both registered in favour of the respondent. The respondent had applied on a "proposed to be used" basis on 30 March 2019, and despite the Trade Marks Registry's own Examination Report dated 21 May 2019 specifically citing PENTA as a conflicting mark under Section 11(1), the Registry had granted registration on the basis of an inadequate two-paragraph reply. The respondent, for the first time before the court, claimed inspiration from Gurudwara Shri Paonta Sahib and relied on AI-generated linguistic research to justify adoption of PONTA.
Decision: The Delhi High Court allowed the cancellation petitions under Section 57(2) of the Trade Marks Act, 1999, held PONTA deceptively similar to PENTA in visual, structural, and conceptual terms, rejected the belated religious inspiration defence as an afterthought not placed before the Registry, declined to rely on unauthenticated AI-generated linguistic evidence, held that Section 12 protection for honest concurrent use was unavailable given the mala fide nature of adoption, and directed the Registrar of Trade Marks to remove both the word mark and device mark PONTA from the Register of Trade Marks within four weeks.
