Trademark Infringement vs Passing Off in India, Explained

In 2016, the Supreme Court settled a fight between two halwa sellers from Tirunelveli. One side held a registered trademark for the name. The other held something older: decades of goodwill in ‘Iruttukadai Halwa’, built by a shop famous for opening only after dark.

The unregistered side won. In S. Syed Mohideen v. P. Sulochana Bai, the Court held that a prior user’s passing-off rights sit above a later registration. A certificate lost to a reputation.

That result confuses founders because Indian law runs two parallel systems. Trademark infringement is a statutory action under Section 29 of the Trade Marks Act, 1999, reserved for registered proprietors. Passing off is a common-law action that protects goodwill whether you registered or not, and Section 27(2) expressly preserves it. By the end of this guide you will know what each action demands, when an unregistered brand can still sue, and how the remedies compare.

Two rights, one brand: how the actions split

Registration creates a property right in the mark itself. Once your mark is on the register, Section 28 gives you the exclusive right to use it for the goods and services it covers, and Section 29 lets you sue anyone who crosses that line.

Passing off protects something different: not the mark, but the goodwill your business has earned under it. The action existed long before the statute, and Parliament deliberately left it untouched. Section 27(2) says nothing in the Act affects your right to sue anyone for passing off goods or services as yours.

So a registered owner sues for infringement. An unregistered brand sues for passing off. And a registered owner with real market goodwill can, and usually should, plead both in the same suit.

Registration gives you a sword the statute made. Goodwill gives you a shield the market made. Strong brands carry both.

Section 29: what statutory infringement covers

Section 29 is a checklist, and it reaches further than most founders expect. The core case is simple: someone uses a mark identical or deceptively similar to your registered mark, for goods or services the registration covers, in a way likely to confuse buyers.

But the section does not stop at lookalike labels. It covers use of your mark inside a company or trading name. It covers advertising that takes unfair advantage of your mark’s repute. And where your mark has a reputation in India, it can even cover use on completely unrelated goods — the anti-dilution rule that protects famous names.

• Identical mark, identical goods. The clearest case. Courts presume confusion and move fastest here.
• Similar mark or similar goods. You must show a likelihood of confusion among ordinary buyers with imperfect memory — the standard Indian courts apply to real shoppers, not lawyers with both labels side by side.
• Dissimilar goods. Available where your registered mark has a reputation in India and the use takes unfair advantage of it or damages it.
• Trade names and advertising. Using your mark as a business name, or in comparative advertising that rides on your reputation, can also infringe.

Your biggest procedural advantage is the certificate itself. Section 31 treats registration as prima facie evidence of the mark’s validity, so you start the suit with the presumption on your side instead of spending months proving reputation. That head start is exactly why trademark registration in India pays for itself the first time trouble arrives.

Passing off: the classical trinity

Passing off has no checklist in the Act. Courts apply the ‘classical trinity’ distilled in the English Jif Lemon case, Reckitt & Colman v. Borden, and adopted across Indian decisions: goodwill, misrepresentation, and damage. Miss any one, and the action fails. We unpacked the case itself in our Jif Lemon passing-off deep-dive.

1. Goodwill

You must show the market connects the name, packaging, or get-up with your business. That means paper: sales figures, invoices going back years, advertising spend, distributor lists, press coverage. Goodwill is proved with documents, not adjectives.

2. Misrepresentation

The defendant’s use must be likely to deceive buyers into believing their goods are yours or connected to you. Intent helps your case but is not required; even an innocent misrepresentation can support the action if buyers are actually likely to be misled.

3. Damage

Actual or probable damage: diverted sales, lost licensing income, or injury to reputation when the copier’s quality is poor. Courts accept a likelihood of damage — you do not need to wait for the wound to bleed before filing.

Infringement compares two marks. Passing off compares two businesses in the mind of a buyer.

When an unregistered brand can still sue

Founders often assume no registration means no rights. Indian courts have rejected that idea repeatedly, and two cases show how far passing off stretches.

In N.R. Dongre v. Whirlpool Corporation, Whirlpool had no live Indian registration at the time, yet it restrained a Delhi company from selling ‘Whirlpool’ washing machines. The courts accepted transborder reputation: goodwill had reached Indian consumers through advertising and word of mouth even before large-scale local sales.

Iruttukadai Halwa proved the sharper point: prior use beats later registration. The Act itself agrees. Section 34 protects a prior user against a registered proprietor, which is why examiners and judges keep returning to the same question — who used the mark first in the market?

The catch is the burden. An unregistered plaintiff must build goodwill invoice by invoice. A registered plaintiff walks in with a certificate. If you are still unregistered, start preserving proof of use today, and run a trademark search before someone files your name out from under you.

India is first-to-file, but the courtroom still respects who came first in the market. Prove it with paper.

Infringement vs passing off: the head-to-head

• Source of the right. Infringement: Section 29 of the Trade Marks Act. Passing off: common law, expressly preserved by Section 27(2).
• Who can sue. Infringement: the registered proprietor and permitted users. Passing off: anyone with goodwill, registered or not.
• What you prove. Infringement: registration plus deceptive similarity; confusion is presumed when both mark and goods are identical. Passing off: the full trinity, every single time.
• Evidence load. Infringement is certificate-led. Passing off is evidence-heavy — sales records, advertising, packaging history, trade declarations.
• Forum advantage. Section 134 lets a registered proprietor sue where the plaintiff resides or carries on business. A pure passing-off plaintiff generally follows the defendant under the ordinary civil procedure rules.
• Defences you will face. Infringement suits attract validity attacks and prior-use defences. Passing-off suits fight over whether goodwill and deception exist at all.

Remedies: what the court can actually give

Section 135 lists the reliefs for both infringement and passing off, and the menu is nearly identical. Injunction first, money second.

1. Injunction. Interim and permanent orders restraining use of the mark. This is the real prize — most Indian trademark suits are effectively decided at the interim stage, years before any trial.
2. Damages or account of profits. You elect one, not both. Damages compensate your loss; an account of profits strips the infringer’s gain.
3. Delivery-up. Infringing labels, packaging, and goods surrendered for destruction so they cannot re-enter the market.

In practice, the injunction does almost all the work. A copier restrained from using the name loses the commercial reason to fight, which is why enforcement moves fast through an experienced IP litigation team rather than slowly toward a trial that may never happen.

One practical difference: courts grant interim relief more readily in infringement, because the certificate settles the threshold question of your right. A passing-off plaintiff must win the goodwill argument before the injunction question even opens.

What this means for your filing strategy

Passing off is a safety net, not a strategy. It rescues brands that built real goodwill, but it is slower, costlier, and evidence-hungry compared to walking in with a certificate under your arm.

The playbook is short. File early — government fees start at ₹4,500 per class for individuals, startups, and MSMEs. Search before you file so you are not the defendant in someone else’s suit. And preserve use evidence continuously, because even registered owners lean on it when a prior-use defence surfaces.

The halwa shop won without a certificate. It also spent years in court proving what a ₹4,500 filing presumes on day one.

Register the brand, keep the goodwill file current, and when a copier appears, plead both actions and move for an interim injunction quickly. The law hands you two weapons. Use them together.
