The Prior-Use Defence in Indian Trademark Law: Section 34 Explained

Indian trademark law is broadly first-to-file. Section 28 of the Trade Marks Act, 1999 grants the registered proprietor the exclusive right to use the mark in relation to the goods or services covered by registration. But the Act has an important limit: Section 34 protects the prior user. A trader who has continuously used a mark in India before the registrant's date of first use cannot be stopped by the registration. The Supreme Court confirmed this in 2016 in S. Syed Mohideen v. P. Sulochana Bai, where a registered proprietor lost to a continuous prior user under Section 34.

This guide explains what Section 34 actually says, what the defence requires, what evidence makes it work, and where the prior-use principle has saved Indian businesses from later registrants.

The text of Section 34

Section 34 of the Trade Marks Act provides:

"Nothing in this Act shall entitle the proprietor or a registered user of a registered trade mark to interfere with or restrain the use by any person of a trade mark identical with or nearly resembling it in relation to goods or services in relation to which that person ... has continuously used that trade mark from a date prior to (a) the use of the first-mentioned trade mark in relation to those goods or services by the proprietor or a predecessor in title of his, or (b) the date of registration of the first-mentioned trade mark, whichever is the earlier..."

In one sentence: the registered proprietor cannot stop someone who got there first. The defence is statutory; it does not require independent passing-off proof; and it survives even against a registered mark that became "incontestable" through long registration.

First-to-file is the rule. Prior use is the exception. The exception is broad in India.

S. Syed Mohideen — what the Supreme Court held

The parties had been using the trade mark "Iruttu Kadai Halwa" for sweets in the town of Tirunelveli. The plaintiff (P. Sulochana Bai) had used the mark since 1900, in the same shop, in the same town. The defendant (S. Syed Mohideen) obtained a registration of an identical mark and sued the plaintiff for infringement. The Supreme Court (2016) held in favour of the unregistered prior user. The reasoning:

• Section 34 protects continuous use from a date prior to the registrant's first use or the registration date
• The prior user need not register; the protection is statutory and runs against the later registrant
• Goodwill built through continuous prior use is the property of the prior user, and Section 34 codifies that protection

S. Syed Mohideen v. P. Sulochana Bai, (2016) 2 SCC 683. The case is now the leading Supreme Court authority on Section 34 and the prior-use defence in India.

Earlier authority — Milmet Oftho

The 2004 decision Milmet Oftho Industries v. Allergan Inc. ((2004) 12 SCC 624) is the older authority frequently cited alongside Section 34 issues. The case turned on transborder reputation, but the underlying principle — that prior use of a mark anywhere matters in determining trademark rights — has fed into Section 34 interpretation. Milmet Oftho is the conceptual ancestor; Syed Mohideen is the operational rule.

What the defence requires

To make Section 34 work, the prior user must prove:

1. Continuous use — actual use of the mark, not just intent or a one-off transaction. Gaps in use, especially long ones, weaken the defence.
2. Use prior to the registrant's first use or registration date — whichever is earlier. The relevant comparison is to the earlier of those two dates.
3. Use in the relevant goods or services — Section 34 is class-specific. Prior use in shoes does not protect against a later registration in chocolates.
4. Use in the same geography or one that overlaps — limited regional prior use will protect within the region of use, and may not extend to areas the prior user never traded in

What the defence does not do

Section 34 is a defence, not a cause of action. It lets the prior user keep using the mark in the goods, services and geography of prior use. It does not:

• Cancel the registrant's registration (that requires a Section 47 / 57 rectification petition)
• Stop the registrant from using the mark in other classes or other markets
• Give the prior user the right to enforce the mark against third parties as an infringement claim (that requires registration or a passing-off case)

The clean strategy for an Indian prior user is to file for registration while invoking Section 34 if challenged in the interim, and to file a rectification petition against the conflicting registration.

The geography question

Section 34 does not explicitly limit prior-use protection geographically, but Indian courts have applied common-sense reasoning. A neighbourhood sweet shop's prior use will protect within its trading region; a national retailer's prior use will protect across India. The principle is functional: the protection extends as far as the goodwill extends. Beyond that, the prior user gains no rights, and the registrant retains the field.

The takeaway

India is a first-to-file jurisdiction with a meaningful prior-use safety net. Section 34 protects continuous honest use against later registrants — even against marks registered for years. The Supreme Court's Syed Mohideen decision is the practitioner's anchor citation. For owners of decades-old Indian businesses, the message is: file your trade mark anyway, but if you have not, your continuous use is not legally worthless. For investors and acquirers conducting IP due diligence on Indian targets, the message is also clear: a clean trademark register is not enough — the prior-use file matters too.
