A Chennai-based spice brand discovered that a competitor had been selling a near-identical product under a phonetically similar name for fourteen months. The packaging was different, the price was lower, and the goods were reaching markets where the original brand had spent a decade building recognition. By the time the brand owner approached counsel, distributors were already receiving complaints from customers who had purchased the wrong product.
The question their lawyers had to answer first was not “did infringement occur” it almost certainly did. The question was: which court, which relief, and how fast?
Trademark infringement in India is not merely a legal concept. It is a commercial emergency for the business experiencing it, and it operates within a specific statutory and procedural framework that determines whether a brand owner can stop the damage within days or is trapped in years of litigation. This guide explains that framework starting with how infringement is legally defined and decided, moving through five landmark cases that shaped the law, and ending with the practical steps every brand owner needs to take when they discover their trademark is being used without authorisation.
The governing statute: Trademark rights and infringement in India are governed by the Trade Marks Act, 1999 and the Trade Marks Rules, 2017, administered by the Trade Marks Registry under the Office of the Controller General of Patents, Designs and Trade Marks. Infringement suits are filed in civil courts under the procedural framework of the Code of Civil Procedure, 1908, with additional jurisdiction provisions under the Trade Marks Act itself.
What Constitutes Trademark Infringement Under Indian Law?
How does Section 29 of the Trade Marks Act, 1999 define infringement?
Trademark infringement in India is defined under Section 29 of the Trade Marks Act, 1999. The provision covers several categories of infringement, which together address the full range of commercially harmful uses of another party’s mark.
Section 29(1) covers the most straightforward category: where a person uses a mark that is identical to a registered trademark in relation to identical goods or services. No proof of confusion is required; identity on both counts is itself presumed to cause confusion.
Section 29(2) covers the more common and commercially significant category: where a person uses a mark that is identical or similar to a registered trademark in relation to identical or similar goods or services, where such use results in a likelihood of confusion on the part of the public, including the likelihood of association with the registered mark. This is the provision most trademark infringement suits are fought under, and the battleground for the deceptive similarity test.
Section 29(4) extends protection to well-known marks beyond the registered class of goods or services. Where a registered mark is well-known, using an identical or similar mark in relation to any goods or services, even entirely different ones constitutes infringement if such use takes unfair advantage of, or is detrimental to, the distinctive character or repute of the well-known mark. This is the dilution provision.
Section 29(5) makes the use of a registered trademark as a trade name or company name an infringement where the goods or services deal with the registered goods or services.
Registered vs. unregistered marks: Section 29 applies only to registered trademarks. The owner of an unregistered mark has no statutory infringement remedy under the Trade Marks Act they must rely on the common law remedy of passing off, which requires proof of goodwill, misrepresentation, and damage. Registration under the Trade Marks Act converts the right from a common law remedy into a statutory one, shifting several burdens of proof in the registered owner’s favour.
Key Takeaway: Trademark infringement under Section 29 TMA 1999 is established by showing: (1) a registered trademark exists; (2) the defendant is using an identical or similar mark; (3) in relation to identical or similar goods or services; and (4) such use is likely to cause confusion in the minds of the relevant public. For well-known marks, the goods/services requirement falls away under Section 29(4). [INTERNAL LINK: Trademark Registration Services Unimarks Legal Solutions]
The Legal Test: How Indian Courts Decide Deceptive Similarity
What factors do Indian courts apply when assessing whether two marks are deceptively similar?
The central question in most trademark infringement cases is whether the defendant’s mark is deceptively similar to the plaintiff’s registered mark meaning whether it is likely to cause confusion or deception in the minds of consumers. The Supreme Court of India established the governing multi-factor test in a landmark 2001 judgment that remains the foundational authority for all subsequent deceptive similarity analysis.
Cadila Healthcare Ltd. v. Cadila Pharmaceuticals Ltd. (SC, 2001) — The Leading Authority
(2001) 5 SCC 73
This Supreme Court decision is the single most important Indian judgment on trademark deceptive similarity and is cited in virtually every infringement case involving similar marks. The dispute arose from two pharmaceutical companies, both members of the original Cadila family of companies, using the “Cadila” name after a corporate split. The case reached the Supreme Court on the question of whether the defendant’s use of “Cadila” in its corporate and product names was deceptively similar to the plaintiff’s registered marks.
The Supreme Court used this case to comprehensively articulate the factors a court must assess when determining deceptive similarity in trademark disputes. The Court held that the following factors must be considered:
First, the nature of the marks — whether they are word marks, device marks, composite marks, or some combination. Word marks that sound alike (phonetic similarity) receive particular scrutiny.
Second, the degree of resemblance between the marks assessed on three dimensions simultaneously: visual appearance, phonetic sound, and meaning. All three must be considered; dominance in one dimension can establish deceptive similarity even where the other two differ.
Third, the nature of the goods or services — whether the goods are of a type that receive careful scrutiny by purchasers (such as pharmaceutical products) or goods purchased casually without detailed comparison. Courts apply stricter standards to pharmaceutical marks because of the risk of harm from confusion.
Fourth, the class of purchasers — their education, sophistication, and familiarity with the relevant market. A consumer of industrial chemicals is assessed differently from a consumer of over-the-counter medication or a daily consumer product.
Fifth, the mode of purchasing — whether goods are purchased by brand name request, by visual identification, over-the-counter, or through an intermediary. Goods sold by oral request to a shopkeeper are more susceptible to phonetic confusion than goods purchased online by visual selection.
Sixth, other surrounding circumstances — including the channels of trade, the geographic market, and any evidence of actual confusion already occurring in the market.
The Supreme Court explicitly held that in pharmaceutical trademark cases, the standard of care is higher because the consequences of confusion between two drug products can be life-threatening. Courts do not require the same degree of similarity to find infringement in pharmaceutical cases as they might in cases involving general consumer products.
Cadila is not just a pharmaceutical industry precedent, it is the general framework applied across all trademark infringement cases in India. Any infringement analysis that does not work through these factors is incomplete.
Key Takeaway: Indian courts assess deceptive similarity through the Cadila multi-factor framework, nature of marks, degree of resemblance (visual, phonetic, meaning), nature of goods, class of purchasers, mode of purchasing, and surrounding circumstances. No single factor is decisive; all must be weighed together. The stricter the consumer harm potential, the stricter the deceptive similarity standard applied.
Four More Landmark Decisions Every Brand Owner Must Know
Which other Indian cases have shaped trademark infringement law in practice?
Kaviraj Pandit Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories (SC, 1965)
AIR 1965 SC 980
This early Supreme Court judgment established the fundamental distinction between an action for trademark infringement and an action for passing off a distinction that remains essential to understanding Indian trademark litigation today.
The Court held that in an infringement action, the registration of the trademark is itself proof of the exclusive right to use the mark. The registered owner need not prove that goodwill or reputation registration confers statutory rights. In a passing off action, by contrast, the plaintiff must prove that they have acquired goodwill in the mark through actual use and public recognition, that the defendant has made a misrepresentation leading or likely to lead the public to believe the defendant’s goods are the plaintiff’s goods, and that actual or probable damage results.
The practical consequence: registration is power. An unregistered mark owner suing in passing off carries significantly heavier evidentiary burdens than a registered trademark owner bringing a Section 29 infringement claim.
Dhodha House v. S.K. Maingi (SC, 2006)
(2006) 9 SCC 41
This Supreme Court judgment is the foundational authority on territorial jurisdiction in trademark infringement cases, specifically, how Section 134 of the Trade Marks Act, 1999 interacts with the general jurisdictional provisions of the Code of Civil Procedure.
The Court held that Section 134(2) grants a trademark owner an additional, more convenient option: filing in the district court within whose jurisdiction the plaintiff resides or carries on business, even if neither the infringement nor the defendant is located in that jurisdiction. This is the “plaintiff’s jurisdiction” exception that significantly improves access to justice for registered trademark owners.
However, the Dhodha House decision also established limits: the plaintiff must genuinely reside or carry on business in the chosen jurisdiction. The additional jurisdiction cannot be fabricated to create a convenient forum.
Indian Performing Rights Society Ltd. v. Sanjay Dalia (SC, 2015)
(2015) 10 SCC 161
This Supreme Court decision refined the Dhodha House jurisdiction framework by addressing the question of abuse. The Court held that where a plaintiff has its principal place of business in one city but seeks to file a suit based on a subordinate office in another city (to gain access to a more plaintiff-friendly court), this constitutes an abuse of the additional jurisdiction granted by Section 134.
The plaintiff must ordinarily file in the court where the principal place of business is located, not in a jurisdiction where only a nominal or secondary office exists. Section 134’s additional jurisdiction provision was designed to provide genuine convenience not to enable forum shopping.
The combined Dhodha House / Sanjay Dalia rule: You may file where you genuinely reside or carry on business as your principal place of business. You may not manufacture jurisdiction by establishing a token office in a preferred court’s territory.
Laxmikant V. Patel v. Chetanbhat Shah (SC, 2002)
AIR 2002 SC 275
This Supreme Court decision is the principal authority on ex parte interim injunctions in trademark and passing off cases the emergency relief mechanism that allows a court to immediately restrain infringement without first hearing the defendant.
The Court held that where a plaintiff establishes a prima facie case of infringement or passing off and demonstrates that the balance of convenience favours restraint and that irreparable harm will result if the injunction is not granted, a court may grant an interim injunction, including on an ex parte basis, without notice to the defendant to preserve the status quo. The Court further held that passing off is a continuous tort, and the plaintiff need not wait for actual harm to accumulate before seeking relief.
This judgment is the legal basis for the rapid-response injunctions that experienced IP practitioners use to stop infringement within hours or days of discovering it rather than waiting months for a hearing on notice.
Key Takeaway: These four cases collectively establish that: registration is the foundation of infringement rights (Durga Dutt Sharma); plaintiffs may file in their home jurisdiction under Section 134 (Dhodha House) but cannot abuse this to forum-shop (Sanjay Dalia); and urgent ex parte injunctions are available where the infringement causes irreparable harm and the balance of convenience favours the plaintiff (Laxmikant Patel).

Where to File: Jurisdiction in Trademark Infringement Suits
Which court has jurisdiction to hear a trademark infringement case in India?
Section 134 of the Trade Marks Act, 1999, governs jurisdiction in trademark infringement suits and grants trademark owners a choice of forums that is more plaintiff-friendly than the general CPC rules.
A trademark infringement suit may be filed in the District Court (or the High Court exercising original civil jurisdiction) within whose local limits:
The defendant resides, carries on business, or personally works for gain, the standard CPC rule; or the plaintiff resides or carries on business, the additional jurisdiction granted specifically for trademark infringement suits under Section 134(2).
High Courts with original civil jurisdiction, the Madras High Court, Delhi High Court, Bombay High Court, and Calcutta High Court, can directly hear trademark infringement cases of sufficient value without the matter passing through lower courts first. These courts also have specialised IP benches with judges who handle trademark matters regularly. The Madras High Court’s IP Division, in particular, has developed a substantial body of trademark jurisprudence covering deceptive similarity, well-known marks, trade dress, and interim relief.
Commercial Courts established under the Commercial Courts Act, 2015, have jurisdiction over high-value intellectual property disputes. These courts follow accelerated timelines under the Commercial Courts Act and are generally more efficient for complex trademark litigation than ordinary civil courts.
Limitation period: Trademark infringement suits must be filed within three years of the date on which the infringement became known to the plaintiff, under the applicable provisions of the Limitation Act, 1963. Missing this window can result in the suit being barred, and while courts have discretion in appropriate cases, relying on limitation extension arguments is strategically risky.
What Remedies Can You Claim? Section 135 TMA 1999
What relief do Indian courts grant in trademark infringement cases?
Section 135 of the Trade Marks Act, 1999 prescribes the reliefs available to a successful plaintiff in a trademark infringement suit. These are the remedies the court may grant, and understanding them matters both for plaintiffs structuring their claim and defendants assessing their exposure.
Injunctions are the primary and most immediately effective remedy. A court may grant a permanent injunction restraining the defendant from further use of the infringing mark. More importantly for commercial purposes, an interim injunction available under Order XXXIX, Rules 1 and 2 of the CPC can be obtained early in proceedings, often within days of filing, to stop the infringement while the case is being decided on the merits. An ex parte interim injunction (without notice to the defendant) is available in urgent cases.
Damages or account of profits — the plaintiff may claim either actual damages suffered as a result of the infringement, or an account of the profits the defendant made through the infringing use. The plaintiff chooses between these two they cannot claim both in the same suit. Where the defendant’s profits are higher than the plaintiff’s provable losses (common in large-scale counterfeiting), account of profits is often the more valuable remedy.
Delivery up — the court may order the delivery up of all infringing goods, labels, packaging, and materials used in the infringement, for destruction or erasure. This prevents the defendant from quietly liquidating infringing stock after an injunction is granted.
Costs — in appropriate cases, courts may award legal costs against an infringer, particularly where the infringement was deliberate or the defendant’s conduct in the litigation was unreasonable.
John Doe / Ashok Kumar orders: For online or counterfeit goods infringement involving unknown defendants, Indian courts including the Delhi High Court and Madras High Court routinely grant John Doe orders (also called Ashok Kumar orders after an early precedent). These are injunctions directed against unnamed defendants “all persons acting in concert with the defendant” which can be served on e-commerce platforms, marketplace operators, customs authorities, and logistics providers to intercept infringing goods without requiring the identity of every infringer to be established in advance.
Key Takeaway: The Section 135 remedies toolkit injunctions (including ex parte interim), damages or account of profits, delivery up, and costs is specifically designed to provide prompt and complete relief to trademark owners. The choice between damages and account of profits is strategic and should be assessed early in the litigation with experienced IP counsel.
Practical Roadmap: Eight Steps When You Discover Trademark Infringement
- Document everything immediately — screenshot the infringing use with timestamps, purchase infringing products if available, record URLs, and note the first date of discovery. This evidence establishes both the fact of infringement and the start of the limitation period.
- Verify your registration is current — confirm the trademark registration is active, the renewal is not overdue, and the mark is registered in the relevant class covering the infringing goods or services. An expired registration cannot ground a Section 29 infringement claim.
- Engage IP counsel before sending any communication — an improperly drafted cease-and-desist letter can prejudice your litigation position. Counsel will assess whether a Section 29 infringement claim or a passing off action (or both) is appropriate, and whether an immediate injunction application is advisable.
- Choose your jurisdiction strategically — under Section 134(2), you may file in your home jurisdiction (principal place of business). Assess the caseload, IP bench availability, and track record of the available courts before filing.
- Consider an immediate interim injunction application — in cases of clear, ongoing infringement causing commercial harm, an application for an ex parte or urgent interim injunction under Order XXXIX CPC can stop the infringement within days. The Laxmikant Patel standard (prima facie case + balance of convenience + irreparable harm) frames the application.
- Choose between damages and account of profits early — you must elect one before the suit concludes. If the defendant’s scale of infringing activity is large and profitable, account of profits may significantly exceed your provable losses. Your counsel should begin gathering intelligence on the defendant’s sales volumes early.
- File within three years — the limitation period under the Limitation Act, 1963 runs from the date infringement became known to you. Do not delay in the hope that the infringement will stop; each passing month of known, unaddressed infringement strengthens the defendant’s limitation defence.
- Consider parallel administrative action — a trademark infringement suit in court can run alongside a non-use cancellation application (Section 47 TMA) against a defendant’s conflicting registration, or an opposition to any pending application they have filed. Coordinating these tracks can significantly improve your overall position.
Conclusion: Registration Is the Foundation; Speed Is the Strategy
The five cases reviewed in this guide, Cadila Healthcare, Durga Dutt Sharma, Dhodha House, IPRS v. Sanjay Dalia, and Laxmikant Patel collectively illustrate a single consistent theme in Indian trademark law: courts take infringement seriously, provide powerful and rapid remedies, and expect registered trademark owners to act promptly and strategically.
Registration converts a trademark from a common law asset requiring expensive proof of goodwill into a statutory right that can be enforced with Section 29 and remedied under Section 135. For any business that has built brand equity in India, registration is not optional; it is the foundation on which all enforcement depends.
