Can Someone Register a Trademark Similar to Yours in India? Here's What the Law Actually Says

The short answer is: they’re not supposed to, but it happens more often than most brand owners expect. The Trade Marks Registry is required to check every new application against existing marks before allowing it to proceed, but this system isn’t foolproof. Similar marks slip through in different classes, examiners occasionally miss a conflicting citation, and once a mark is published, brand owners who aren’t actively monitoring the Trade Marks Journal frequently miss the narrow, non-extendable window to object before it registers. At Sharma Kemp Chambers, this is one of the most common calls I get: a brand owner has just discovered, sometimes years after the fact, that a confusingly similar mark is sitting on the Register, or worse, is actively being used in the market, and wants to know what can still be done.

This guide sets out how Indian law actually decides whether two marks are “too similar” to coexist, why similar marks sometimes do get through the Registry despite the safeguards in place, and the tools available to a brand owner at every stage, before registration, after registration, and once a similar mark is being used in the market.

Quick Answer: Is the Similar Mark a Genuine Problem?

Before the detail, here is the framework I use with clients who’ve just discovered a similar mark:

• Similarity alone is not automatically fatal. The legal question is whether the mark, considered alongside the goods or services it covers, creates a likelihood of confusion or association with your mark in the mind of an ordinary consumer, not whether the two names simply share some resemblance.
• The class matters, unless your mark is well-known. A similar mark in an entirely unrelated class of goods or services generally faces a lower barrier to registration, unless your mark qualifies for the broader, cross-class protection given to well-known marks.
• Timing determines which tool is available to you. A mark that has just been published in the Trade Marks Journal can be stopped through opposition; a mark that has already registered needs rectification; a mark that is actually being used in the market, regardless of its registration status, can be addressed through an infringement or passing-off suit.
• The Registry’s own screening isn’t a guarantee. Marks in different classes, marks examined by different officers with different views on similarity, and marks that simply weren’t flagged during examination do get through, which is precisely why brand owners need their own monitoring in place rather than relying on the Registry to catch every conflict.
• “Similar enough to confuse” is a fact-specific legal test, not a gut feeling. Indian courts apply a well-established multi-factor test, developed specifically to separate genuine confusion risk from coincidental resemblance that causes no real harm.

The Legal Framework: What Makes Two Marks “Too Similar”

Section 9 vs Section 11: Two Different Questions

The Trade Marks Act, 1999 asks two distinct questions before allowing a mark to register. Section 9 asks whether the mark, on its own, is distinctive enough to register at all, regardless of any other existing mark. Section 11 asks the separate question relevant to this guide: whether the mark conflicts with an earlier mark. Under Section 11(1), a mark is refused where it is identical or similar to an earlier Trade mark, covers identical or similar goods or services, and there exists a likelihood of confusion on the part of the public, which expressly includes the likelihood of the public assuming some association between the two marks, even without a full mistaken belief that the goods come from the same source.

The Test for Deceptive Similarity

The leading Indian authority on how courts actually assess similarity is the Supreme Court’s decision in Cadila Health Care Ltd v Cadila Pharmaceuticals Ltd (2001) 5 SCC 73, which laid down a now-standard seven-factor test applied across Trade mark disputes, not just the pharmaceutical context in which the case arose:

1. The nature of the marks, whether they are word marks, label marks, or composite marks combining words and design.

2. The degree of resemblance between the marks, phonetically, visually, and conceptually.

3. The nature of the goods or services in respect of which the marks are used.

4. The similarity in the nature, character, and performance of the rival goods or services.

5. The class of purchasers likely to buy the goods, including their education, intelligence, and the degree of care they are likely to exercise.

6. The mode of purchasing the goods, or placing orders for them.

7. Any other surrounding circumstances relevant to the specific case.

The Court also made a point directly relevant to how strictly this test is applied: these factors don’t carry equal weight in every case, and a stricter standard applies where confusion could have serious real-world consequences, most notably in pharmaceutical products, where the Court held a lesser degree of proof of confusing similarity suffices given the potential health risks of a mistaken purchase. This underlying principle, that the standard of scrutiny should scale with the potential harm from confusion, has informed how courts approach similarity questions well beyond the pharmaceutical sector.

A separate, older but still frequently cited formulation comes from Amritdhara Pharmacy v Satya Deo Gupta (1963) AIR SC 449, where the Supreme Court articulated the relevant perspective as that of “a man of average intelligence and imperfect recollection,” meaning the comparison is not a side-by-side, careful examination of two marks, but a test of what an ordinary consumer, recalling one mark from memory while encountering the other, is likely to be confused by.

Why Classes Matter, and Where the Exception Lies

Because the Nice Classification system divides goods and services into 45 separate classes, a mark registered in one class doesn’t automatically block a similar mark in an unrelated class, since the core concern, likelihood of confusion, is generally lower where the goods or services genuinely don’t overlap or compete in the same market. This is precisely why the same or similar word can coexist as a registered Trade mark for entirely different products in unrelated industries, provided there is no realistic likelihood of the public assuming a common source or association.

The significant exception is Section 11(2), which extends protection to well-known Trade marks against use on dissimilar goods or services where such use, without due cause, would take unfair advantage of, or be detrimental to, the distinctive character or reputation of the well-known mark. This is why an attempt to register a mark identical or very similar to a globally recognised brand, even for entirely unrelated goods, routinely fails: the well-known mark’s protection isn’t confined to its registered classes in the same way an ordinary mark’s protection is.

Honest Concurrent Use: A Narrow Coexistence Route

Section 12 of the Trade Marks Act, 1999 allows the Registrar, in cases of honest concurrent use or other special circumstances, to permit the registration of identical or similar marks by different proprietors for the same or similar goods or services, on such conditions as the Registrar considers proper. This is a narrow, fact-specific route, generally requiring genuine, independent, and long-standing use by both parties without any dishonest intent to trade on the other’s goodwill, and is not a general escape route from Section 11 objections.

How Similar Marks Still Get Through the Registry

Given the framework above, it’s worth understanding concretely why confusingly similar marks do sometimes end up registered despite the system built to prevent this:

• Different classes with genuinely overlapping commercial reality. A mark might be technically filed in a different class from yours, while still competing for the same customers in practice, a gap the Registry’s class-based examination doesn’t always catch, particularly for businesses that operate across adjacent categories (for instance, food products and food delivery services, or apparel and accessories).
• Examiner discretion and inconsistency. Similarity assessments involve genuine judgment calls, and different examiners can reasonably reach different conclusions on borderline cases, particularly for marks that are similar but not identical.
• The four-month opposition window is genuinely easy to miss. If you’re not actively monitoring the Trade Marks Journal for new filings similar to your own mark, a conflicting mark can clear the entire opposition period and proceed to registration without you ever being aware it existed until it’s already registered.
• International and Madrid Protocol filings can move through a separate track, and brand owners who monitor only domestic filings sometimes miss marks entering India through an international registration designating India.

Remedies at Each Stage

Before Registration: Opposition

Once a Trade mark application is examined and accepted, it is advertised in the Trade Marks Journal, opening a strict four-month window (governed by Section 21 of the Trade Marks Act, 1999, read with the Trade Marks Rules, 2017) during which any person, not just a prior registered proprietor, can file a notice of opposition in Form TM-O. This window is non-extendable under any circumstances, a deliberate change made by the 2017 Rules, which removed the Registrar’s earlier discretion to grant a one-month extension. If the applicant fails to file a counter-statement within two months of being served with the opposition, the application is treated as abandoned. This is, in almost every case, the cheapest and fastest point at which to stop a conflicting mark, which is precisely why active monitoring for new filings similar to your own mark is so valuable.

After Registration: Rectification

Once a similar mark has cleared the opposition window and registered, opposition is no longer available, but rectification of the Register under Section 57 of the Trade Marks Act, 1999 remains open, on grounds including that the entry was made without sufficient cause, or wrongly remains on the Register given a genuinely conflicting earlier mark. This route, its procedure, and the practical considerations involved are covered in detail in our companion guide on Trade mark cancellation in India, and remains available to a “person aggrieved” regardless of how long the conflicting mark has already been registered, subject to considerations of delay and acquiescence that can weaken a long-dormant challenge.

Where the Mark Is Actually Being Used: Infringement or Passing Off

Where a similar mark is not just registered but actually being used in the market in a way that is causing, or likely to cause, real confusion, an infringement action under Sections 29 and 134–135 of the Trade Marks Act, 1999 (if your own mark is registered), or a passing-off action under common law (whether or not it is), becomes available independently of any Registry-level opposition or rectification proceeding. This route, including jurisdiction, interim injunctions, and the current position on pre-institution mediation, is covered in detail in our companion guide on filing a Trade mark infringement suit in India.

Step-by-Step: What to Do If You Discover a Similar Mark

Step 1: Determine Exactly What Stage the Similar Mark Is At

Check whether the mark is merely applied for and pending examination, has been advertised and is within its four-month opposition window, has already registered, or is being actively used in the market, since each stage points to a different remedy with a very different cost and timeline.

Step 2: Assess Genuine Similarity Against the Cadila Factors

Before committing to any action, honestly assess the marks against the seven-factor test: how visually, phonetically, and conceptually similar are they, how related are the actual goods or services, and who are the realistic purchasers likely to encounter both marks. Not every superficially similar mark presents a genuine legal risk, and understanding this early avoids pursuing action with a weak underlying case.

Step 3: Check Whether Your Own Mark’s Status Affects Your Options

Confirm whether your own mark is registered (opening the infringement route), well-known (potentially extending your protection across otherwise unrelated classes), or unregistered (limiting you to the passing-off route, which requires you to independently establish goodwill and reputation).

Step 4: Act Within the Opposition Window If the Mark Hasn’t Registered Yet

If the conflicting mark is still within its four-month opposition window, file promptly, since this deadline is strictly enforced with no possibility of extension, and missing it forecloses the opposition route entirely, leaving only the more expensive rectification route once registration completes.

Step 5: Pursue Rectification or Infringement as Appropriate If Registration Has Already Occurred

If the opposition window has passed, assess whether rectification, an infringement or passing-off suit, or both in parallel, is the more appropriate route, based on whether the conflicting mark is currently being used in the market and how urgently that use needs to be stopped.

Step 6: Build a Monitoring System to Catch Future Conflicts Earlier

Whatever the outcome of the current conflict, put a Trade mark watch service in place (commercial watch services exist specifically for this purpose, monitoring new filings similar to your registered marks) so future similar applications are flagged during the opposition window, rather than discovered only after registration.

Practical Checklist

• Register in every class genuinely relevant to your business, not just your primary category, since gaps in your own class coverage are exactly where confusingly similar marks tend to slip through unchallenged.
• Set up an ongoing Trade mark watch, rather than relying on periodic manual searches, since the four-month opposition window is unforgiving and a missed filing can mean the difference between a straightforward opposition and a costly rectification proceeding later.
• Document your mark’s reputation and market recognition on an ongoing basis, since this evidence becomes essential if you ever need to argue for well-known mark status to protect against a similar mark in an unrelated class.
• Don’t assume a different class means no risk. Assess genuine commercial overlap and consumer perception, not just the formal Nice Classification, when deciding whether a similar mark in an adjacent category is worth challenging.
• Move quickly once you spot a genuine conflict. Every stage of this process, opposition, rectification, and infringement, rewards early action and becomes more expensive and less certain the longer a conflicting mark is left unchallenged.

Two Hypothetical Scenarios

Scenario 1: Caught in Time Through Opposition

A specialty coffee brand has a registered mark in Class 30 for coffee products. Through a routine Trade mark watch, it discovers a newly advertised application for a phonetically near-identical mark, filed in Class 43 for café and restaurant services. Recognising the genuine commercial overlap, since coffee brands and coffee shops routinely operate under the same name and target the same consumers regardless of the formal class distinction, the brand files a notice of opposition well within the four-month window, supported by evidence of its own registration, market presence, and the phonetic and conceptual similarity between the marks under the Cadila framework. The opposition succeeds, and the conflicting application is refused before ever reaching registration.

Scenario 2: Missed Opposition, Pursued Through Rectification and Infringement

A regional fashion label discovers, eighteen months after the fact, that a near-identical mark registered in the same class for competing apparel, having cleared the opposition window entirely unnoticed since the label had no monitoring system in place at the time. By now, the conflicting mark is being actively used to sell competing products in overlapping retail channels. The label’s counsel pursues two parallel tracks: a rectification petition under Section 57 challenging the registration itself, and, given the active, ongoing use causing real market confusion, an infringement suit seeking an interim injunction to stop the sales immediately rather than waiting for the rectification proceeding to conclude.

Conclusion

Someone can register a Trade mark similar to yours, and the Registry’s own screening process, while genuinely designed to prevent this, is not infallible: different classes, examiner judgment calls, and a strict, easily missed opposition window all create real gaps. What determines the outcome is less about whether a conflicting mark technically exists, and more about how quickly you catch it, and which of the three available tools, opposition, rectification, or an infringement or passing-off action, fits the stage the conflict is actually at. The businesses that protect their brands most effectively are, almost without exception, the ones running active Trade mark monitoring rather than discovering a conflict only after a customer, a distributor, or a due diligence process points it out.
