What Counts as Trademark Infringement in India? Passing Off and Deceptive Similarity Explained
Deceptively similar names, passing off, and registered infringement are three different things with three different tests. What each one actually means for a brand being monitored, not litigated.

Key takeaways
- Trademark infringement in India is the unauthorised use of a mark identical or deceptively similar to a registered trademark, on the same or related goods or services, under the Trade Marks Act, 1999.
- Passing off is misrepresenting your goods or services as someone else's, damaging their goodwill - it protects unregistered marks too.
- Registered trademark infringement and passing off are different legal grounds - one needs a registration, the other doesn't.
- 'Deceptively similar' is the actual test used, not 'identical' - closeness of overall impression is what matters.
- A trademark legal notice is a formal step with real consequences, not a first move to send casually.
- Monitoring for early-stage misuse is what keeps this a documentation problem instead of a costly dispute later.
Search interest around trademark infringement clusters around a handful of specific, practical questions: what actually counts as infringement, how passing off differs from it, what 'deceptively similar' means in practice, and what a legal notice actually does. Each has a precise answer that gets lost in generic explainers.
This isn't legal advice, and DiReFTY isn't a law firm - what follows is the practical shape of the problem, useful for recognising it early and understanding what a monitoring and documentation function is actually building toward.
Registered infringement vs. passing off
Registered trademark infringement applies when a mark is registered and someone else uses an identical or deceptively similar mark on the same or related goods or services, without permission. The registration itself is the evidentiary anchor - it establishes ownership and scope up front.
Passing off is the older, common-law route, and it doesn't require a registration at all. It protects the goodwill built up in a mark through use, and the test is whether the other party's conduct misrepresents its goods or services as connected to yours, causing damage. An unregistered brand with real market recognition isn't unprotected - it just has to establish reputation and misrepresentation instead of pointing to a certificate.
In practice, a brand often has both routes available at once, and a well-documented case builds evidence usable for either.
What 'deceptively similar' actually means
The test isn't identical marks - it's whether an average consumer, with imperfect recollection, would be confused into thinking the two are connected. Courts look at overall visual, phonetic, and structural similarity, not a side-by-side letter comparison.
A name that changes one letter, a logo with a near-identical layout in a different colour, or a product name that sounds the same when spoken aloud can all clear this test even though they aren't literally identical to the original mark.
Domain names and the same underlying problem
A domain incorporating a registered or well-known mark, registered by someone with no legitimate connection to it, raises the same passing-off and infringement questions as a physical product or listing does - the venue is different, the underlying misrepresentation is the same.
This is why domain monitoring and trademark monitoring tend to sit together operationally: the same brand-name misuse shows up across both surfaces, often from the same source.
What a trademark legal notice actually does
A legal notice is a formal written communication asserting rights and demanding specific action - typically cessation of use, sometimes damages or an account of profits. It's a documented step that can matter later if the dispute escalates, which is exactly why it shouldn't be sent casually or without the underlying evidence already in order.
A notice sent without a properly documented basis - clear evidence of the infringing use, the rights being asserted, and the specific harm - is weaker than one built on a monitoring record showing when the use started, how it evolved, and what confusion it's already caused.
Where DiReFTY sits in this
DiReFTY monitors for brand-name and mark misuse across search, marketplaces, domains, and social platforms, and documents what it finds - timestamps, screenshots, and the pattern of use - to the standard that supports a later enforcement step, whichever route a brand and its legal counsel decide fits: registered infringement, passing off, or both.
The coordination work - flagging the misuse early, building the evidence file, and handing off a documented case rather than a vague complaint - is what keeps enforcement coordination distinct from legal representation, which DiReFTY does not provide.
Frequently asked questions
Do I need a registered trademark to take action against a copycat?
Not necessarily. Passing off protects a brand's built-up goodwill even without registration, though a registration generally makes the case more straightforward to establish and enforce.
What is a deceptively similar trademark?
A deceptively similar trademark is one that so nearly resembles another mark that it is likely to deceive or cause confusion - the phrase used in India's Trade Marks Act, 1999. The test is the overall visual, phonetic, and structural impression on an average consumer with imperfect recollection, not a letter-by-letter comparison.
What is passing off in trademark law?
Passing off is a common-law action against someone who misrepresents their goods or services as connected to yours, damaging the goodwill you have built. It does not need a registered trademark, but you must show reputation, misrepresentation, and damage.
Is a similar-sounding name automatically infringement?
Not automatically - it depends on how similar it is, whether it's used on the same or related goods or services, and whether it's likely to confuse an average consumer. 'Deceptively similar' is the real test, not identical.
What's the difference between trademark infringement and passing off?
Infringement is a statutory right tied to a registration. Passing off is a common-law claim protecting goodwill, available even without one. A brand can often rely on both at once.
Should I send a legal notice as soon as I spot a similar brand name?
A notice is a formal step with consequences, best sent once the use and its impact are properly documented, rather than as an immediate reaction to first noticing it.
Does DiReFTY handle the legal notice or litigation itself?
No - DiReFTY monitors, documents, and coordinates enforcement steps; it is not a law firm and does not provide legal representation. Legal notices and litigation sit with a brand's own legal counsel, working from the documentation DiReFTY provides.
