Trade Marks Act 1999 Section 29: Infringement of Registered Trade Marks (2026)

Explainer · Trade Marks Law

Updated for 2026 · Claw Editorial

Section 29 of the Trade Marks Act, 1999 is the infringement provision. It tells you when someone has infringed a registered trade mark, which is the first thing you must show to win an infringement suit. In short, Section 29 covers a person who is not the registered owner or a permitted user and who, in the course of trade, uses a mark that is identical or deceptively similar to a registered mark in a way that is likely to confuse the public. It also protects marks with a reputation against use that rides on that reputation, even on different goods. This explainer sets out what each part of Section 29 covers, the defences, and what the courts have said. Last verified October 2026.

01What Section 29 says

Section 29 applies only to registered trade marks. If a mark is not registered, the owner has to sue for passing off instead, which is a different and harder case. For a registered mark, Section 29 gives the owner a statutory right to stop others from using a confusingly similar mark.

Only a registered mark unlocks Section 29. To register, see the trade mark registration process in India. To understand well-known marks, which get extra protection under Section 29(4), see well-known trade marks in India.

02The main kinds of infringement

Section 29 is built in layers. The common threads are that the person is not the owner or permitted user, the use is in the course of trade, and it is used as a trade mark.

So infringement is not only putting a copied logo on a product. It can be using the mark in a business name, in advertising, or even as a spoken word in trade.

03When confusion is presumed

Usually the owner must show that the public is likely to be confused. But Section 29(3) gives a shortcut. Where the rival mark is identical to the registered mark and is used on identical goods or services, the court shall presume that confusion is likely.

This is a strong help to the owner in clear copying cases. The burden shifts, and the rival has to displace the presumption rather than the owner having to prove confusion from scratch. Where the marks or goods are only similar, not identical, confusion has to be shown, judged through the eyes of an average consumer with imperfect recollection.

04Marks with a reputation

Section 29(4) protects famous marks beyond their own category. Normally infringement needs similar goods, because confusion is the test. But a well-known mark can be harmed even where the goods are completely different, for example a famous soft-drink name used on shoes.

Section 29(4) applies where the registered mark has a reputation in India, the rival mark is identical or similar, the goods are different, and the use without due cause takes unfair advantage of, or is harmful to, the distinctive character or repute of the mark. This is the dilution idea: the law stops others from cashing in on a reputation that the owner built.

05Defences under Section 30

Section 29 does not stand alone. Section 30 lists uses that are not infringement, and any infringement case must be read together with it. Common defences include:

• Honest descriptive use of a word to describe the kind, quality or purpose of goods, rather than as a trade mark.
• Use to show the purpose of goods, such as spare parts or accessories, where it is reasonably necessary.
• Genuine goods put on the market by the owner, which the owner cannot then control on resale.

So a defendant will often argue that the word was used honestly and descriptively, not as a brand. Whether that succeeds depends on how the word was actually used.

06What the courts have said

The Supreme Court in Renaissance Hotel Holdings Inc. v. B. Vijaya Sai stressed that Section 29 must be read as a whole, and warned against reading one sub-section in isolation to defeat a clear case of infringement. The Court looked at identical marks used in the same field and held that the statutory scheme must be given full effect.

High Courts regularly grant interim injunctions where a mark identical to a registered mark is used on identical goods, treating the Section 29(3) presumption as a strong factor. On the reputation limb, courts have protected well-known marks against use on unrelated goods where the reputation was clearly made out. The practical point is that identity plus same goods is the strongest case, while similarity needs careful proof of confusion.

07A practical note

If you own a registered mark, Section 29 is your main weapon, but it works best when you act early and keep proof. Watch the market and the trade marks journal for similar marks, keep evidence of your sales and advertising to show reputation, and send a cease and desist before going to court where that makes sense.

Catching infringement early is far easier than unwinding it later. For an ongoing watch on copycats, see tracking trade mark infringement cases in Indian courts, and for defending and policing your brand, see trade mark opposition and brand protection.
