Trademark Infringement vs. Passing Off: What Every Brand Owner Must Understand

Two businesses. Similar products. Confusingly similar names. One has a registered trademark. The other has been trading under its name for eight years without ever filing an application.

Both walk into a lawyer’s office with the same complaint. Someone is copying our brand. Both leave with completely different advice. The registered brand owner files an infringement action. The unregistered one relies on passing off. Same commercial harm on the surface. Underneath it, different legal frameworks, different evidence requirements, different timelines, and a burden of proof that sits on opposite ends of the scale.

Trademark infringement vs passing off is the distinction that determines which route goes to court, how quickly interim relief can be obtained, and whether the case is built on a certificate or on eight years of sales records. Getting this wrong at the start of a dispute is expensive.

What Is Trademark Infringement?

Trademark infringement is a statutory remedy under Section 29 of the Trade Marks Act 1999. It applies when an unauthorised party uses a mark identical or deceptively similar to a registered trademark for identical or similar goods or services in a way that creates a likelihood of confusion among consumers. Registration is the prerequisite. Without it, Section 29 is not available as a cause of action regardless of how obvious the copying is or how well-known the brand has become.

The statutory framework does significant work for the registered trademark owner. Once registration is established and the similar mark is shown, the court presumes exclusivity and likelihood of consumer confusion. The defendant must rebut that presumption rather than the claimant building the entire case from scratch. That presumption is what makes infringement proceedings faster and procedurally cleaner than passing off.

What triggers infringement under Section 29:

• Using a mark identical to the registered mark for identical goods or services
• Using a mark deceptively similar to the registered mark for identical or similar goods or services where consumer confusion is likely
• Using a mark that takes unfair advantage of the registered mark’s reputation even for dissimilar goods, where the registered mark has a reputation in India

The identical mark on identical goods case is the clearest. The deceptively similar mark on similar goods case is where most commercial disputes sit, and where the quality of the registered mark’s legal counsel determines how the similarity argument is framed.

What Is Passing Off?

Passing off is a common law tort recognised under Section 27 of the Trade Marks Act 1999. It protects the goodwill and reputation associated with both registered and unregistered marks when one party misrepresents its goods or services as those of another. No registration is required. What is required instead is proof of three things: goodwill built through use in the market, a misrepresentation by the defendant, and damage caused or likely to be caused by that misrepresentation.

The Supreme Court in Cadila Healthcare Ltd. v. Cadila Pharmaceuticals Ltd. reaffirmed the principles governing passing-off actions and emphasised that the court must assess the likelihood of deception or confusion by considering the overall circumstances of the case. A passing-off action is generally understood through the classical trinity of goodwill or reputation, misrepresentation, and damage or likelihood of damage

Goodwill is the accumulated reputation the brand has built through actual trading. It is proven through sales figures, advertising spend, duration of use, geographic spread, press coverage, retailer relationships, and evidence that consumers associate the mark with the claimant’s goods or services. A brand used exclusively in one city has goodwill there and not elsewhere. A brand distributed nationally has national goodwill. The geographic scope of the goodwill determines where the passing off claim can be brought and where it cannot.

Misrepresentation is the false impression the defendant’s conduct creates in the minds of consumers that its goods or services are those of, or are associated with, the claimant. Intent is completely irrelevant here. A new entrant that independently arrives at a confusingly similar name without any knowledge of the claimant’s existence is still misrepresenting in law. The test is the effect on consumers, not the defendant’s state of mind. Deliberate copying strengthens the case on damages. It is not required to establish liability.

Damage is the harm caused or likely to be caused by the misrepresentation. Lost sales, diverted custom, reputational harm where the defendant’s inferior goods reach customers who believe they are buying from the claimant, or probable damage that the court accepts as the natural consequence of the confusion continuing. In pharmaceutical passing off cases, the damage element is rarely contested because the potential harm from patients receiving the wrong medication is self-evident.

What Are the Key Differences Between Trademark Infringement vs Passing Off?

The differences shape every strategic decision from the moment the dispute begins.

The burden of proof difference is the one that matters most in practice. An infringement claimant shows the registration certificate and the similar mark and asks the court to apply the statutory presumption. A passing off claimant assembles a bundle of sales records, advertising invoices, customer testimonials, press coverage, retailer affidavits, and market survey evidence before the hearing begins. Both can win. One starts from a significantly stronger procedural position.

What Is a Real Example of Passing Off Trademark?

A regional food brand has been selling packaged snacks under a distinctive name for six years across three southern states. Genuine market presence. Regular distribution. Recognisable packaging. No trademark registration because the founders intended to file and never prioritised it.

A large national FMCG company launches a similar snack product in the same three states under a confusingly similar name with packaging that uses similar colours and design elements. The regional brand’s sales drop in the specific districts where the national product is available. Retailers report consumer confusion.

The regional brand cannot file an infringement action. No registration means no Section 29 remedy. What it has is a passing off claim built on six years of sales records establishing goodwill in those three states, market survey evidence showing consumer confusion between the two products, and documented evidence of sales decline in districts where the national product is available. The geographic scope of the goodwill matters: if the national company had also launched in states where the regional brand has no presence, the passing off claim would fail in those states entirely because there is no goodwill there to protect.

A second scenario that comes up regularly: a technology startup trades under a distinctive name for four years. A larger competitor files for and receives trademark registration for the same name. The startup now faces an infringement claim from the registered trademark owner. But the startup’s four years of prior use is simultaneously a defence to the infringement claim and the foundation of a passing off counterclaim against the registered trademark owner. Prior use before the registration date defeats the infringement action and supports an application to cancel the registration. What looked like a straightforward infringement matter becomes a two-sided dispute the moment the prior use evidence is assembled.

What Are the Remedies and Defences for Infringement and Passing Off?

Civil remedies are available in both trademark infringement and passing off: interim and permanent injunctions, monetary damages, account of profits, and delivery up or destruction of infringing goods and materials. Criminal remedies under Sections 103 to 105 of the Trade Marks Act apply to infringement cases and carry imprisonment and significant fines. The defences available differ materially between the two causes of action.

Civil Remedies

Injunctions are the immediate priority in most brand disputes. An interim injunction stops the defendant’s conduct while the full case is decided. For infringement, the registered mark establishes the prima facie right to protection and interim injunctions are obtained relatively quickly. For passing off, the interim injunction application requires producing evidence of goodwill and misrepresentation at the early hearing stage. Cases where the passing off claimant arrives in court without assembled evidence lose the interim application regardless of how clear the copying is.

Monetary damages are calculated on actual loss: lost sales, diverted custom, reputational harm from inferior quality goods sold under a similar name. Expert witnesses on brand valuation and market impact are standard in significant cases.

Account of profits requires the defendant to hand over what it earned from the infringing or passing off conduct. This is most useful where the defendant has been commercially active at scale and its profits from the conduct exceed what the claimant can demonstrate as its own losses.

Delivery up and destruction of infringing goods, packaging, labels, and related materials accompanies most successful orders in both types of proceedings.

Criminal Remedies

Sections 103 to 105 of the Trade Marks Act provide for criminal prosecution for deliberate trademark infringement. First offences carry imprisonment of six months to three years and fines of Rs. 50,000 to Rs. 2 lakh. Repeat offences carry higher ranges on both counts. Criminal prosecution is standard in counterfeiting cases. In commercial disputes between legitimate competing businesses, civil proceedings are the norm.

Defences to Infringement

Fair use: The defendant uses the mark descriptively, not as a brand identifier, and without creating consumer confusion. A business describing a product’s characteristics using a word that happens to be another party’s registered trademark in an entirely different context may invoke this.

Prior use: The defendant used the mark before the claimant’s registration date. This defeats the infringement claim on the existing use and supports a cancellation application against the registered mark.

Honest concurrent use: Both parties independently developed similar marks without knowledge of each other. Courts may permit both to continue with geographic or product category limitations attached to the order.

Non-confusing use: The similar mark operates for such different goods, in such a different market segment, or with such different trade dress that no likelihood of consumer confusion actually arises.

Defences to Passing Off

No goodwill: The claimant has no established reputation in the relevant territory. A brand operating only in the north cannot claim passing off protection from a copycat operating in the south where it has no sales, no distribution, and no customer recognition.

No misrepresentation: The marks are different enough, or the goods are in categories far enough apart, that no consumer would form a false impression that the goods come from or are associated with the claimant.

Independent creation: The defendant developed its mark without any knowledge of the claimant. This does not defeat the claim since passing off requires no intent, but it bears on the quantum of damages.

No damage: No actual or probable harm has resulted or is likely to result. Difficult to sustain convincingly where the marks are genuinely confusingly similar in the same market sector.

Why the Distinction Matters Commercially

The trademark infringement vs passing off choice at the start of a dispute affects timeline, cost, the probability of obtaining interim relief early, and ultimately the commercial outcome.

Registered trademark owners move faster. The certificate does the work at the interim stage. The presumption of exclusivity applies. The defendant challenges rather than the claimant proves.

Unregistered brand owners carry the full evidentiary burden and must assemble the case before filing rather than during proceedings. The evidence bundle for a passing off claim takes time to build properly. Sales records going back multiple years, advertising invoices, retailer affidavits, customer evidence, market surveys. A passing off claim filed without this assembled and organised tends to fail at the interim stage even where the copying is commercially obvious.

The registration fee is a fraction of the cost of building a passing off case during a live dispute under time pressure. Every business trading under a distinctive name without a trademark registration is accepting a litigation risk that one application to the Trade Marks Registry substantially reduces.

Conclusion

Trademark infringement vs passing off is a distinction that matters from the moment a dispute is identified, not from when it reaches a courtroom. The wrong choice of remedy, or the absence of registration that forces the passing off route when an infringement action would have been cleaner and faster, costs money and time that most businesses would rather not spend.
