Deceptive Similarity Test Cases
1. Introduction
Deceptive similarity is a core concept in trademark law in India, governed by the Trade Marks Act, 1999 (as amended).
Definition:
A mark is deceptively similar to another if it is likely to cause confusion among the public regarding the origin of goods/services.
Section 2(1)(zb) of the Trade Marks Act, 1999 defines a “deceptively similar” mark:
A mark shall be deemed to be deceptively similar to another if it so nearly resembles that other mark as to be likely to deceive or cause confusion.
Key Principles:
Global/overall impression test – the mark should be considered as a whole.
Similarity in sound, spelling, appearance – relevant factors.
Nature of goods/services – similarity in goods/services increases likelihood of confusion.
Class of consumers – sophistication of the buyer matters.
Prior use and reputation – earlier mark with reputation has wider protection.
2. Factors Considered in Deceptive Similarity
Visual similarity: Spelling, letters, logos, packaging.
Phonetic similarity: How the mark sounds when spoken.
Conceptual similarity: Meaning or idea conveyed by the mark.
Nature of goods/services: Whether they are related or identical.
Market conditions and class of buyers: Ordinary public vs. skilled buyers.
Test used by courts:
“Whether an ordinary consumer, with imperfect recollection, is likely to be misled into believing that the goods/services originate from the same source.”
3. Key Indian Case Laws on Deceptive Similarity
Case 1: Cadila Health Care Ltd v. Cadila Pharmaceuticals Ltd (2001) – Supreme Court
Facts:
Two pharmaceutical companies using the mark “CADILA”.
Plaintiff alleged the defendant’s mark was deceptively similar, confusing customers.
Court’s Analysis:
Considered overall impression, pronunciation, visual similarity.
Noted that in pharma, buyers are often sophisticated but pharmacy assistants or doctors may rely on memory.
Even minor differences cannot remove deceptive similarity if overall impression is the same.
Held:
The defendant’s mark was deceptively similar.
Deception is judged from perspective of ordinary consumer with imperfect recollection.
Principle Established:
Visual and phonetic similarity, plus nature of goods, can constitute deceptive similarity.
Case 2: Tata Sons Ltd v. Manu Kosuri (2007) – Delhi High Court
Facts:
Alleged infringing use of TATA in business name “TATA Motors Auto Services”.
Plaintiff argued deceptive similarity and passing off.
Court’s Analysis:
Examined reputation of TATA (famous mark).
Considered phonetic similarity and impact on ordinary consumers.
Emphasized distinctiveness and brand recognition.
Held:
Likelihood of confusion existed; defendant restrained from using the mark.
Principle Established:
Famous marks enjoy broader protection; even partial similarity can mislead consumers.
Case 3: ITC Ltd v. Blue Moon Food Products (2002) – Delhi High Court
Facts:
ITC’s “SUNFEAST” biscuits alleged infringement by “SUNMOON”.
Court’s Analysis:
Compared spelling, sound, and concept of marks.
Nature of goods identical (biscuits).
Considered ordinary consumers with imperfect recollection.
Held:
Defendant’s mark was deceptively similar.
Injunction granted.
Principle Established:
Combination of visual and phonetic similarity, plus same class of goods, satisfies the deceptive similarity test.
Case 4: Amritdhara Pharmacy v. Satya Deo Gupta (1963) – Supreme Court
Facts:
Famous mark: “AMRITDHARA” for hair oil
Defendant used “AMRITDHAARA”
Court’s Analysis:
Difference of one letter is immaterial if overall impression is same.

Defendant’s mark deceptively similar; injunction granted.
Principle Established:
Overall impression outweighs minor differences in spelling.
Case 5: Reckitt & Colman of India Ltd v. F.Hoffmann-La Roche Ltd (1993) – Delhi High Court
Facts:
Trademark dispute over similar packaging and mark for pharmaceutical product.

Looked at get-up, packaging, spelling, pronunciation.
Ordinary purchaser may confuse products based on overall presentation, not exact spelling.
Held:
Defendant restrained; deceptive similarity established.
Principle Established:
Deceptive similarity can include trade dress and packaging, not just the mark itself.
Case 6: Nestlé India Ltd v. Mondelez India Foods Pvt Ltd (2019) – Delhi High Court
Facts:
“KitKat” chocolate bar vs. “Kitkatty” bar.
Court’s Analysis:
Marks visually similar; pronunciation similar.
Products identical in nature.
Considered ordinary consumer with imperfect recollection.
Held:
Defendant’s mark deceptively similar; injunction granted.
Principle Established:
Conceptual similarity + phonetic similarity + identical goods = strong case for deceptive similarity.
Case 7: Bata India Ltd v. Paragon Footwear Pvt Ltd (2007) – Delhi High Court
Facts:
Bata’s footwear vs. similar sounding mark “BATAA” by another company.
Court’s Analysis:
Considered reputation of Bata.
Minor variations do not prevent deception if ordinary consumers can be misled.
Held:
Deceptive similarity established; defendant restrained.
Principle Established:
Deceptive similarity focuses on likelihood of confusion, not exact replication.
4. Tests Summarized by Courts
Ordinary Consumer Test: Would an ordinary buyer be misled?
Imperfect Memory Test: Consumers rarely recall every detail.
Overall Impression Test: Minor differences ignored if overall impression same.
Nature of Goods Test: Similar goods increase probability of confusion.
Famous Marks Test: Well-known marks get broader protection.
5. Key Takeaways
Deceptive similarity is factual, not purely legal. Courts examine sound, look, meaning, and context.
Minor spelling or pronunciation differences do not protect infringers.
Reputation of the mark strengthens protection.
Identical or similar goods/services make deception more likely.
Packaging, branding, and get-up can also contribute to deceptive similarity.
