Indian trademark law rests on a compact set of Supreme Court and High Court decisions that give the Trade Marks Act, 1999 — and the common law of passing off it preserves — their working shape. Whether the question is deceptive similarity between rival marks, the rights of a prior user against a registrant, the protection available to foreign brands, or the status of domain names, one of the ten judgments below almost always supplies the controlling principle. For each case, this guide covers the background, the statutory provisions engaged, the court's reasoning, its treatment by later courts, and the practical takeaway for brand owners.

1. Kaviraj Pandit Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories, AIR 1965 SC 980
Background
Both parties sold Ayurvedic preparations under marks built around the word "Navaratna". The registered proprietor sued for infringement; the dispute forced the Court to articulate precisely how a statutory infringement claim differs from the common-law action for passing off.
Statutory provisions
Decided under the Trade Marks Act, 1940, the decision now maps onto Sections 28 and 29 of the Trade Marks Act, 1999 (rights conferred by registration and infringement) and Section 27(2) (preservation of passing off).
What the court held
In an infringement action the comparison is between the registered mark and the impugned mark: if the defendant has taken the essential features of the registered mark, infringement is made out, and neither the defendant's added distinguishing matter, honest intention, nor absence of actual confusion will ordinarily save it. In passing off, by contrast, the whole get-up, packaging, trade dress and manner of use are examined, and the plaintiff must establish likelihood of deception. The onus and the subject of comparison differ fundamentally between the two actions.
Subsequent treatment
The dichotomy has been followed without dissent for six decades — including by the Supreme Court itself in Cadila (2001) — and is quoted in virtually every combined infringement-and-passing-off suit filed in India today.
Practical impact
Registration materially strengthens enforcement: a registered proprietor need not prove reputation or actual confusion, only that the essential features of its mark have been taken. Unregistered brand owners can still sue in passing off, but they carry the heavier evidentiary burden of proving goodwill and misrepresentation. This is the core commercial case for timely trademark registration.
2. Amritdhara Pharmacy v. Satya Deo Gupta, AIR 1963 SC 449
Background
The proprietor of the mark AMRITDHARA for a medicinal preparation opposed registration of LAKSHMANDHARA for a similar product, contending the rival mark was deceptively similar.
Statutory provisions
Decided under the Trade Marks Act, 1940; the standard it articulates now governs deceptive similarity assessments under Sections 9(2)(a), 11 and 29 of the Trade Marks Act, 1999.
What the court held
Similarity is judged by the overall impression a mark leaves on a purchaser of average intelligence and imperfect recollection — not by a meticulous side-by-side comparison of syllables. The Court gave phonetic similarity independent weight, holding that to the ordinary Indian consumer the overall structural and phonetic resemblance between AMRITDHARA and LAKSHMANDHARA was likely to deceive.
Subsequent treatment
Continuously relied upon: the "imperfect recollection" standard is the lens through which every modern deceptive-similarity analysis is conducted, and it was expressly woven into the multi-factor framework in Cadila (2001) and applied in Nandhini Deluxe (2018). It has never been doubted.
Practical impact
Clearance searches and opposition strategy must account for phonetic and conceptual similarity as heard and remembered by ordinary consumers — including transliteration across Indian languages — not merely for visual differences a lawyer can point to in a side-by-side exhibit.
3. Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd., (2001) 5 SCC 73
Background
Two successor companies of the Cadila group sold anti-malarial drugs under the marks FALCIGO and FALCITAB. The dispute reached the Supreme Court from the interlocutory stage of what was, notably, a passing off action — the guidance the Court gave was framed for deciding deceptive similarity in unregistered-mark disputes, though it is now applied across infringement and opposition contexts as well.
Statutory provisions
The judgment construes the concept of deceptive similarity that runs through the Trade Marks Act — today Sections 2(1)(h), 9, 11 and 29 of the 1999 Act — while the action itself rested on the common law preserved by what is now Section 27(2).
What the court held
The Court laid down the now-canonical factors: the nature of the marks (word, label, composite); the degree of phonetic and visual resemblance and similarity in idea; the nature of the goods; the similarity in the nature, character and performance of rival goods; the class of purchasers, their education and intelligence, and the care they exercise; the mode of purchase; and any other relevant surrounding circumstances. Critically for the pharmaceutical sector, it mandated a stricter approach for medicinal products, since confusion between drugs can have life-threatening consequences.
Subsequent treatment
This is the single most-cited Indian trademark judgment. The Supreme Court applied it in Nandhini Deluxe (2018), and every High Court applies its framework in similarity disputes; it has never been overruled or doubted.
Practical impact
Brand adoption in regulated sectors — above all pharma — must be conservative: even marks derived from a common ingredient or ailment name can be enjoined if the overall impression overlaps. The factor-based structure also means evidence strategy (consumer profile, trade channels, purchase conditions) can be decisive at the injunction stage.
4. N.R. Dongre v. Whirlpool Corporation, (1996) 5 SCC 714
Background
Whirlpool's Indian registration for WHIRLPOOL had lapsed, and a local trader obtained registration and began selling washing machines under the mark. Whirlpool sued in passing off, relying on its international reputation and its limited prior sales (including to the US Embassy) and advertising reach in India.
Statutory provisions
The action was in passing off, preserved by what is now Section 27(2) of the Trade Marks Act, 1999; the case also illustrates that registration under the Act (now Section 28) confers no immunity against a prior-reputation passing off claim.
What the court held
The Supreme Court affirmed the Delhi High Court's interim injunction, recognising that reputation can travel ahead of trade: through international advertising and spillover circulation, WHIRLPOOL had acquired protectable goodwill in India despite negligible local sales, and the local registrant's use amounted to passing off.
Subsequent treatment
Followed for two decades as the leading trans-border reputation authority, its breadth was recalibrated by Toyota v. Prius (2017), which requires proof that goodwill actually subsists within India. Dongre remains good law for the proposition that reputation may precede sales, but the territorial evidentiary threshold is now set by Toyota.
Practical impact
Foreign brands entering India late are not remediless against squatters — but since Toyota, they must assemble concrete India-facing evidence (media reach, enquiries, sales channels, internet presence directed at India) rather than relying on global renown alone. Defensive registration ahead of market entry remains far cheaper than litigation.
5. Toyota Jidosha Kabushiki Kaisha v. Prius Auto Industries Ltd., (2018) 2 SCC 1
Background
Toyota sued Indian auto-parts makers who had registered and used PRIUS since 2001 — years before Toyota's hybrid car of that name was sold in India (2010). Toyota's passing off claim rested on the mark's international fame at the time the defendants adopted it.
Statutory provisions
Passing off under the common law preserved by Section 27(2) of the Trade Marks Act, 1999; the judgment is also the Supreme Court's fullest engagement with the goodwill element of the classical trinity (goodwill, misrepresentation, damage).
What the court held
The Court adopted the territoriality principle over the universality doctrine: a claimant must prove that its reputation and goodwill existed within India at the date the defendant adopted the mark. On the evidence — limited Indian media penetration of the Prius launch in the late 1990s and no Indian sales until 2010 — Toyota failed to establish Indian goodwill at the relevant date, and its claim was dismissed.
Subsequent treatment
Toyota is now the controlling authority on territoriality and is applied by High Courts in every passing off dispute involving foreign or pre-entry marks. It recalibrated rather than overruled Dongre, and it expressly relied on Syed Mohideen for the primacy of common-law rights.
Practical impact
Timing is everything: the goodwill inquiry is anchored to the date of the defendant's adoption, so foreign brand owners should preserve dated evidence of Indian-directed reputation — and file early. For Indian businesses, honest adoption before a foreign mark's reputation reaches India is a genuine defence.
6. S. Syed Mohideen v. P. Sulochana Bai, (2016) 2 SCC 683
Background
Both parties held registrations containing "Iruttukadai Halwa" for halwa shops in Tirunelveli; the respondent's family had used the name since 1900, the appellant registered and used it much later. The question was whose rights prevail when both are registered.
Statutory provisions
Sections 27(2), 28(3) and 34 of the Trade Marks Act, 1999 — the preservation of passing off, the position between rival registrants, and the saving of vested rights of prior users.
What the court held
The rights of a prior user are superior to those of a subsequent registrant. Registration is not the source of trademark rights but statutory recognition of rights that arise from use; the scheme of the 1999 Act itself (Sections 27(2), 28(3), 34) shows that common-law rights ride above registration. A passing off action therefore lies even against a registered proprietor.
Subsequent treatment
Expressly relied upon by the Supreme Court in Toyota v. Prius and now standard authority in every prior-user-versus-registrant dispute; also invoked by the Delhi High Court's 2025 Division Bench in the Crocs trade-dress litigation for the independence of common-law remedies.
Practical impact
A registration certificate is not a shield against a genuine senior user. Due diligence before adoption must go beyond the Register to marketplace use — and businesses with long-standing unregistered marks retain powerful enforcement rights, though registration remains the prudent course for evidentiary and remedial advantages.
7. Nandhini Deluxe v. Karnataka Co-operative Milk Producers Federation Ltd., (2018) 9 SCC 183
Background
NANDHINI DELUXE restaurants (in use since 1989) sought registration in various food classes; the dairy cooperative behind the well-known NANDINI milk brand (in use since 1985) opposed, asserting deceptive similarity and reputation.
Statutory provisions
Sections 9, 11 and the class-based registration scheme of the Trade Marks Act, 1999, applied through the Cadila framework.
What the court held
Applying the Cadila factors, the Court held the marks could coexist: the goods and services, trade channels and consumption contexts differed (restaurant services versus dairy products), the visual presentation of the marks differed, NANDINI/NANDHINI is a common personal name of limited inherent distinctiveness, and a proprietor of a mark for particular goods does not thereby monopolise the name across an entire class or all classes.
Subsequent treatment
Frequently cited in cross-class and cross-channel disputes as authority that mark similarity alone is not determinative; treated as a faithful application of Cadila, not a departure from it.
Practical impact
Opposition outcomes turn on the full commercial matrix — realistic overlap of goods, channels and consumers — not on mark resemblance in the abstract. Brand owners should nonetheless note the decision's limits: for well-known marks with proven spillover reputation, cross-class protection under Section 11(2) remains available on proper evidence.
8. Laxmikant V. Patel v. Chetanbhai Shah, (2002) 3 SCC 65
Background
The plaintiff had run a photo studio under the name "Muktajivan Colour Lab" for years; the defendant commenced an identical business under a deceptively similar name in the same city. The lower courts refused interim relief for want of proof of actual damage.
Statutory provisions
Passing off preserved by Section 27(2) of the Trade Marks Act, 1999 (the judgment was among the first to note the 1999 Act's expanded definitions embracing trade names), with interim relief governed by Order XXXIX CPC.
What the court held
A trading name or business name, even unregistered, is protectable goodwill; likelihood of injury suffices, and a plaintiff need not wait for actual damage to accrue. In clear cases of a probability of deception, an injunction should follow promptly — dishonest intention is not a prerequisite.
Subsequent treatment
Undisturbed and widely applied for trade-name protection and the prompt-injunction principle; it was among the authorities the Delhi High Court's Division Bench drew on in the 2025 Crocs litigation for the breadth of the passing off remedy.
Practical impact
Service businesses and proprietorships trading under unregistered names have real, enforceable rights — and can obtain interim relief quickly on showing probable deception. Conversely, adopting a name similar to an established local business invites early injunction even absent proof of lost sales.
9. Yahoo! Inc. v. Akash Arora, 1999 (19) PTC 201 (Del)
Background
The defendants registered "yahooindia.com" and offered internet services similar to those of Yahoo! Inc., which held the yahoo.com domain and trademark registrations in numerous jurisdictions (though not, at the time, in India).
Statutory provisions
The action lay in passing off (now preserved by Section 27(2) of the Trade Marks Act, 1999), since Indian statute law did not — and still does not — separately regulate domain names.
What the court held
A domain name performs the same source-identifying function as a trademark and deserves equal protection. "Yahooindia" was deceptively similar to YAHOO!, the disclaimer offered by the defendants was insufficient, and internet users' likelihood of confusion justified an injunction.
Subsequent treatment
Though a Single Judge decision, it has been consistently followed in Indian cybersquatting cases, and its reasoning was carried to apex level in Satyam Infoway v. Sifynet Solutions (2004). It is regarded as settled law.
Practical impact
Domain names are enforceable brand assets in India, and cybersquatting is actionable in passing off in addition to UDRP/INDRP administrative remedies. Businesses should register key domains and variants defensively as part of brand clearance.
10. Satyam Infoway Ltd. v. Sifynet Solutions Pvt. Ltd., (2004) 6 SCC 145
Background
Satyam Infoway, proprietor of the "Sify" brand and domains, sued a later adopter of "siffynet" domains. The jurisdictional question for the Supreme Court was whether internet domain names are subject to the legal norms applicable to trademarks at all.
Statutory provisions
Passing off under the common law preserved by Section 27(2) of the Trade Marks Act, 1999; the Court noted the absence of any India-specific domain-name legislation, making common-law protection the operative regime.
What the court held
A domain name is a business identifier capable of distinguishing goods and services, and as such can enjoy protection equivalent to a trademark; the law of passing off applies to domain-name disputes. On the facts, "Sify" had acquired distinctiveness and the rival domains were confusingly similar, warranting relief.
Subsequent treatment
The definitive apex-court authority on domain-name protection, cited in virtually every subsequent cybersquatting dispute; no contrary authority has emerged.
Practical impact
Online-first businesses can enforce their brands against confusing domains through the civil courts with the full range of injunctive and monetary remedies — an important complement to registrar-level dispute policies, which offer transfer or cancellation but not damages.

Frequently Asked Questions
What is the test for deceptive similarity of trademarks in India?
The governing framework comes from Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd. (2001) 5 SCC 73, which requires courts to weigh the nature of the marks, their degree of resemblance (phonetic, visual and in idea), the nature of the goods, the class of purchasers, the mode of purchase and surrounding circumstances — judged through the eyes of a person of average intelligence and imperfect recollection, a standard drawn from Amritdhara Pharmacy v. Satya Deo Gupta (1963). Pharmaceutical marks attract stricter scrutiny because confusion can endanger health.
What is the difference between trademark infringement and passing off in India?
As settled in Kaviraj Pandit Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories (AIR 1965 SC 980), infringement is a statutory action protecting a registered mark — the comparison is with the registered mark itself, and if the essential features are taken, added matter and even absence of intent are largely irrelevant. Passing off is a common-law action protecting goodwill: the plaintiff must prove reputation, misrepresentation judged on the whole get-up and trade dress, and likelihood of damage.
Can a foreign brand not sold in India stop a local business from using its mark?
Only if it proves goodwill within India. N.R. Dongre v. Whirlpool Corporation (1996) recognised trans-border reputation flowing through advertising spillover, but Toyota Jidosha Kabushiki Kaisha v. Prius Auto Industries (2018) 2 SCC 1 reaffirmed the territoriality principle: international reputation alone is insufficient — the claimant must establish that its reputation and goodwill had crossed into the Indian market at the relevant date.
Does prior use of a trademark defeat a later registration in India?
Yes. In S. Syed Mohideen v. P. Sulochana Bai (2016) 2 SCC 683, the Supreme Court held that the rights of a prior user are superior to those of a subsequent registrant, because registration merely recognises pre-existing common-law rights. Sections 27(2) and 34 of the Trade Marks Act, 1999 preserve the prior user's position, and a passing off action lies even against a registered proprietor.
Are domain names protected as trademarks in India?
Yes. Satyam Infoway Ltd. v. Sifynet Solutions Pvt. Ltd. (2004) 6 SCC 145 confirmed at Supreme Court level — building on Yahoo! Inc. v. Akash Arora (1999, Delhi High Court) — that a domain name functions as a source identifier and is protectable under the law of passing off, since India has no separate domain-name statute.
