Deceptive similarity under Section 2(1)(h) of the Trade Marks Act, 1999 means a mark so nearly resembling another that it is likely to deceive or cause confusion among consumers. Indian courts apply a test focused on the overall impression a mark creates on a person of average intelligence and imperfect recollection — comparing phonetic sound, visual appearance, and structural similarity, rather than a side-by-side technical comparison. With 23+ years of IP litigation experience, we help clients both assert and defend against deceptive similarity claims.
What is Deceptive Similarity?
Deceptive similarity is defined in Section 2(1)(h) of the Trade Marks Act, 1999 as a mark that so nearly resembles another mark that it is likely to deceive or cause confusion. It is one of the most frequently litigated concepts in Indian trademark law — the outcome of opposition proceedings, infringement suits, and rectification petitions very often turns entirely on whether two marks are found to be deceptively similar.

The Legal Test Courts Apply
Indian courts do not compare two marks side by side, letter by letter, the way a linguist might. Instead, they apply the "person of average intelligence and imperfect recollection" standard — asking whether an ordinary customer, who does not have both marks in front of them at the same time and is relying on a general, imperfect memory of the earlier mark, would likely be confused or deceived by the later mark.
This test deliberately favours the earlier trademark owner in borderline cases, on the reasoning that it is better to err on the side of preventing consumer confusion than to allow a close imitation on a technicality.
Key Factors Courts Consider
- Overall structural similarityHow the marks look and read as a whole, not just individual letters or words
- Nature and class of goodsWhether the goods are of the same description and sold through similar trade channels
- Class of purchasersThe likely level of care and attention of the typical buyer of those goods
- Mode of purchaseWhether the goods are ordered by name (increasing reliance on imperfect recollection) or examined closely before purchase
- Distinctiveness of the earlier markHighly distinctive, coined or arbitrary marks receive a wider scope of protection than descriptive ones
Phonetic, Visual and Structural Similarity
Courts typically assess similarity across three dimensions, and a mark can be found deceptively similar even if it fails on some of these while passing others:
| Type | What It Examines |
|---|---|
| Phonetic similarity | How the marks sound when spoken aloud — often the most important factor, since many customers ask for products by name verbally |
| Visual similarity | How the marks appear on packaging, signage or in print — font, layout, colour scheme and overall visual impression |
| Structural/conceptual similarity | Whether the marks share a similar underlying idea, root word, or structural pattern, even with different spellings |
Why the Class of Goods Matters
For an ordinary registered trademark, deceptive similarity is generally assessed only in relation to the same or similar goods or services. However, for a mark that qualifies as well-known, Section 11(2) extends this protection across entirely dissimilar goods, if the use would take unfair advantage of, or be detrimental to, the earlier mark's distinctive character.
How This Plays Out in Real Cases
See it in real cases: In Toyota vs Tech Square Engineering, the Delhi High Court examined whether ALPHARD, used on unrelated goods, could still cause confusion given Toyota's global reputation. In Columbia Pictures vs Registrar, the near-identical marks GHOSTBUSTERS and GHOST BUSTER were compared not just on spelling, but on phonetic and structural resemblance and the likelihood that consumers would assume a connection between the two.

Frequently Asked Questions
Do two trademarks need to be identical to be considered deceptively similar?
No. Deceptive similarity does not require identical marks — it only requires that the marks so nearly resemble each other that an ordinary customer with an imperfect recollection of the earlier mark would likely be confused or deceived by the later one.
What is the "person of average intelligence and imperfect recollection" test?
This is the legal standard Indian courts use to assess similarity — rather than comparing two marks side by side in detail, courts ask whether an ordinary customer, relying on a general and imperfect memory of the earlier mark, would likely be deceived or confused by the later mark.
Is phonetic similarity enough to prove deceptive similarity?
Phonetic similarity is a significant factor and can be sufficient on its own in many cases, particularly for goods commonly ordered verbally, but courts typically also weigh visual and structural similarity together with the nature of the goods and class of purchasers before reaching a conclusion.
Can a mark be deceptively similar even for completely different goods?
Generally, deceptive similarity is assessed for the same or similar goods. However, if the earlier mark qualifies as well-known under Section 11(2) of the Trade Marks Act, protection can extend to entirely dissimilar goods if the later use would take unfair advantage of or harm the earlier mark's reputation.
Who decides whether two marks are deceptively similar?
During the application process, the Trade Marks Registrar assesses similarity during examination and opposition proceedings. If the matter proceeds to litigation — such as an infringement suit or a rectification petition — the relevant court makes the final determination based on evidence and legal argument.
