Legal Notice for Trademark Infringement in India: Format and Relief

A brand spends four years building a name, then finds the same name on a competitor's packaging two streets away. Or worse, on an online marketplace listing that undercuts its price and ships a product it never made. Customers call the real company's helpline to complain about the copy, and the goodwill that took years to build starts leaking away. A legal notice for trademark infringement is how that stops before it becomes irreversible.

The notice does two jobs. It creates a dated record that the proprietor objected as soon as it learned of the use, which matters for any later claim of acquiescence. And it gives the infringer a clear, final chance to stop, remove stock and change the name without litigation. Most infringers are small traders who did not search the register before adopting a name; a well-drafted notice resolves the matter in weeks. This guide sets out the format, the statutory provisions, the evidence to gather first, and the mistakes that weaken an otherwise strong case.

Legal notice for trademark infringement: what counts as infringement

Section 29 of the Trade Marks Act 1999 defines infringement. A registered proprietor's rights are infringed when another person uses, in the course of trade, an identical or deceptively similar mark in relation to the goods or services covered by the registration, without authority. The use must be in a manner that is likely to confuse the public or to take unfair advantage of the mark's reputation.

Infringement also arises where a similar mark is used for different goods where the registered mark has a reputation in India and the use takes unfair advantage of or is detrimental to its distinctive character. Separately, the common law remedy of passing off protects an unregistered mark where the proprietor can show goodwill, misrepresentation and damage. A proprietor without registration can still send a notice, but it must be framed as passing off, not infringement.

Section 30 lists the limits on the effect of registration. It permits bona fide use of a person's own name or address, use of descriptive terms, and use that does not confuse. These are the defences an infringer will raise, and the notice should address them in advance where the facts allow.

Checks to complete before the notice goes out

The single most common error in Indian trademark notices is sending one without checking the register. A public search on the Trade Marks Registry portal will show whether the defendant has filed or obtained a registration, the class, the goods or services, and the status of the application. If the defendant holds a registration, the proper course may be rectification proceedings rather than an infringement notice.

Confirm the class and the goods

Trademark rights are class-specific. A registration in Class 25 for clothing does not prevent a restaurant from using the same name in Class 43. The notice must state the class and the goods or services for which the mark is registered, and the defendant's goods must fall within that class or within the scope of the reputation-based provision. A notice that claims infringement across unrelated classes without justification invites a reply that destroys the claim's credibility.

Establish use and reputation

Registration gives the proprietor the right to sue, but use establishes the strength of the case. The notice should reference the date of first use, the annual sales figures, the advertising spend, the number of outlets or distributors, and any awards or press coverage. These facts support the claim for interim injunction, because courts weigh the balance of convenience and the irreparable harm to the proprietor's goodwill. For passing off, use and reputation are the entire case.

Evidence of actual confusion

Confusion need not be proved for infringement, but evidence of it strengthens the notice considerably. Customer complaints, misdirected emails, marketplace reviews referring to the wrong product, and invoices returned to the wrong address are all useful. The notice should annexe this evidence rather than assert confusion in general terms.

Essential contents of the notice

The notice should be drafted on the proprietor's advocate's letterhead and should read as a factual record with a legal conclusion. The following contents are standard.

• Proprietor's title. The registered mark, the registration number, the class, the goods or services, and the date of registration, with the certificate annexed.
• First use and reputation. The date of first commercial use, sales and advertising figures, and market presence, supported by documents.
• The infringing mark. A description of the defendant's mark, where and how it is used, and the date the use was discovered, with photographs or screenshots.
• Similarity analysis. A comparison of the marks phonetically, visually and conceptually, and the goods or services covered, showing likelihood of confusion.
• Absence of authority. A statement that no licence or consent was given, and that any claimed authorisation is denied.
• Demands. Immediate cessation of use, removal of listings and signage, withdrawal of stock, change of name or mark, and delivery up or destruction of infringing material.
• Accounts and damages. A demand for an account of profits or payment of damages, with the basis of computation.
• Deadline. Typically seven to fifteen days, given the ongoing harm.
• Consequence. A statement that a suit for infringement or passing off, with an application for interim injunction and costs, will be filed.
• Reservation of rights. A clause preserving the right to pursue criminal remedies under the Trade Marks Act 1999 for falsification and false application of trademarks.

Enclosures typically include the registration certificate, the first-use evidence, screenshots with timestamps, and a comparison chart of the two marks placed side by side.

Relief available and what to demand

Damages and account of profits are alternative remedies. The notice should elect one. Where the infringer is a large distributor with visible sales, an account of profits usually produces more; where the loss is a measurable drop in the proprietor's own sales, damages are more appropriate. The notice should state the figure claimed or the basis on which it will be computed.

Stamp duty, service and marketplace enforcement

Stamp duty on a trademark notice varies by state and is generally nominal. The current requirement should be confirmed with the sub-registrar or the local bar. Registration of the notice is never required. Serve the notice by registered post with acknowledgement due and by email to the official address of the infringing business. Where the business is a company or LLP, serve the registered office and the directors or partners named in the registry records.

For online listings, send a separate complaint to the marketplace's brand protection or grievance team, with the registration certificate, the infringing listing URL and the specific ground. Most major marketplaces act on a complete complaint within days. The legal notice and the platform complaint should be sent in parallel, because the platform action is faster while the notice creates the legal record.

If the infringement continues after the deadline, file the suit promptly. Delay is the enemy in trademark cases: courts weigh the plaintiff's conduct, and a proprietor who waits a year after discovering the infringement may be refused an interim injunction on the ground of acquiescence. Prepare the plaint and the injunction application before the deadline expires so that filing happens the next working day.

Common mistakes in trademark notices

The first is claiming rights over a descriptive word. If the mark is a common word used descriptively, the registration may be weak and the notice may provoke a rectification petition. The second is failing to plead the class. A notice that does not identify the registered class and the goods cannot establish infringement.

The third is threatening criminal action for an ordinary commercial dispute. Criminal remedies under the Trade Marks Act 1999 are meant for counterfeiting and deliberate piracy; using them as a bargaining tool in a legitimate parallel-use dispute is counterproductive. The fourth is sending the notice to the trading name rather than the legal entity. The fifth is demanding a settlement figure in the notice without any basis. The sixth is failing to preserve the evidence of the infringing use before it is taken down.

Frequently asked questions

Can I send a trademark notice without registration?

Yes, but the claim must be framed as passing off rather than infringement. You will need to prove goodwill in the mark, misrepresentation by the defendant and damage to your business. Registration makes the claim much simpler because infringement does not require proof of goodwill or confusion in the same way.

How long does a trademark registration last?

Ten years from the date of application, renewable indefinitely for further periods of ten years on payment of the renewal fee. If the renewal is not paid within the prescribed period, the registration can be removed from the register. Proprietors should diarise the renewal date and monitor the register for conflicting applications.

What if the infringer is using the mark in a different class?

Infringement may still arise under the reputation-based provision where your mark has a reputation in India and the use takes unfair advantage of it. Otherwise, the claim is passing off. The notice should set out the reputation evidence and explain why the defendant's goods are connected in the public mind to yours.

Does the notice have to give a specific number of days?

No statute fixes the period. Seven to fifteen days is standard, reflecting the ongoing harm. A longer period weakens the case for urgent interim relief, while a period that is too short may be treated as unreasonable. The deadline should be realistic but firm.

Can I stop an online seller using my brand name in listing keywords?

Yes. Using a registered mark as a keyword, in metadata or in a listing title to divert traffic is use in the course of trade and can amount to infringement. The notice should identify the specific listings and send a parallel complaint to the marketplace's brand protection team for removal.

What is the limitation period for a trademark suit?

Under the Limitation Act 1963, a suit for infringement or passing off is generally governed by the three-year period for suits relating to injury to property. Each infringing sale can give a fresh cause of action, but delay still affects the grant of interim relief. Send the notice as soon as the use is discovered.
