Two ayurvedic medicines. One sold as AMRITDHARA since the early 1900s, the other as LAKSHMANDHARA since 1923. In 1963, the Supreme Court had to decide whether an ordinary Indian buyer would mix them up.
The answer produced the most quoted standard in Indian trademark law: marks must be judged through the eyes of a purchaser of average intelligence and imperfect recollection. Six decades later, that single idea still decides most Section 11 objections, oppositions, and infringement suits in India.
This is the story of Amritdhara Pharmacy v Satya Deo Gupta — what was argued, what the Court held, and how the test it laid down will be applied to your brand name the day you file.
The dispute: two tonics, one suffix
Amritdhara Pharmacy had sold a medicinal preparation under the name AMRITDHARA since the beginning of the twentieth century. The product was a household ayurvedic remedy, advertised widely and sold across India.
Satya Deo Gupta applied to register LAKSHMANDHARA for a similar ayurvedic preparation, claiming use since 1923, with sales concentrated in Uttar Pradesh. Amritdhara Pharmacy opposed the application, arguing the name was deceptively similar to its own.
The case was fought under the Trade Marks Act 1940, the law that governed before today’s Trade Marks Act 1999. The statute has changed. The question — will buyers confuse these two names? — has not.
Registrar, High Court, Supreme Court: three answers
The Registrar found the two names deceptively similar. But he still allowed LAKSHMANDHARA onto the register, confined to Uttar Pradesh, because Amritdhara Pharmacy had known about the rival product for years and done nothing — a finding of honest concurrent use and acquiescence.
On appeal, the Allahabad High Court took the opposite view on similarity. It broke the words into parts — AMRIT and DHARA, LAKSHMAN and DHARA — and reasoned that the distinct first halves made confusion unlikely.
The Supreme Court rejected that dissection. It held the two names, taken as whole words, were similar enough to deceive or cause confusion. Yet it restored the Registrar’s order on acquiescence, so the Uttar Pradesh registration survived. Both sides walked away with half a victory.
Buyers remember impressions, not spellings.
The average buyer test, in plain words
The Court asked a deceptively simple question: who actually buys this product, and how do they buy it? The answer was ordinary Indians — including villagers — picking up an everyday ayurvedic remedy, often asking for it by name at a shop counter.
Such a buyer is not a lawyer with both labels side by side. The Court described a purchaser of average intelligence and imperfect recollection — someone who carries a general impression of a name, not a letter-by-letter memory of it.
Measured that way, AMRITDHARA and LAKSHMANDHARA are dangerously close. Both are long composite Hindi words. Both end in DHARA. Both name a medicine for similar everyday ailments. The overall structural and phonetic similarity mattered more than the different opening syllables.
Why the Court refused to split the words
The High Court’s mistake was etymology. It treated the buyer as someone who parses Sanskrit roots — AMRIT as nectar, LAKSHMAN as the name from the Ramayana — and concludes the products come from different houses.
The Supreme Court said real buyers do no such analysis. A word mark is remembered as a whole, by its look and its sound together. The Court drew on the settled English approach — the Pianotist line of cases — which weighs the look of the marks, their sound, the goods they cover, and the customers who buy them.
- Compare wholes, not fragments. Neither side’s mark gets chopped into prefix and suffix for the comparison.
- Sound carries weight. Medicines asked for verbally across a counter are judged heavily on phonetics.
- Context matters. The nature of the goods and the sophistication of the buyer set the strictness of the test.
- First impression decides. The test is the buyer’s recollection at the moment of purchase, not a studied side-by-side review.
No customer reads your trademark the way your lawyer does.
The twist: Lakshmandhara still kept its registration
Here is the part founders skip. Having found the marks confusingly similar, the Supreme Court still let LAKSHMANDHARA stay registered for Uttar Pradesh. Why? Because Amritdhara Pharmacy had watched the rival product being sold and advertised for years without objecting.
That silence amounted to acquiescence. The law protects vigilant owners, not sleeping ones. A brand owner who tolerates a lookalike for a decade cannot suddenly demand its erasure.
The modern lesson is direct: watch the market and the Trade Marks Journal continuously. India gives you a 4-month window to oppose a published application — a deadline explained in our guide to the trademark opposition process in India. Miss enough windows for long enough, and Amritdhara says you may forfeit the right to complain. A professional trademark watch service exists precisely so this never happens to you.
A right you never enforce slowly stops being a right.

Under Section 11 of the Trade Marks Act 1999 (the relative-grounds provision), an examiner must refuse a mark that is confusingly similar to an earlier mark for similar goods. In practice, examiners and courts run the Amritdhara test: whole-mark comparison, phonetic weight, imperfect recollection.
That has three practical consequences before you spend a rupee on branding. First, a spelling tweak does not create a new trademark — AMRUTDHARA would have lost just as badly. Second, phonetic clearance matters as much as visual clearance, which is why a proper knock-out check follows the method in our guide on how to do a trademark search in India. Third, similarity is judged against your actual buyer — a ₹150 balm faces a stricter test than enterprise software bought after three demos.
If your search comes back clean, file quickly. India is first-to-file, and trademark registration costs ₹4,500 per class in government fees for individuals, startups, and MSMEs. If an examiner objects anyway, a well-built objection reply filed within the 30-day deadline resolves most Section 11 citations.
Amritdhara’s long shadow
Later benchmarks stand on this case. The Supreme Court’s pharmaceutical-marks decision in Cadila Health Care v Cadila Pharmaceuticals (2001) built its factor list on the same foundation: overall similarity, buyer profile, imperfect recollection. Passing-off cases run the same comparison when testing misrepresentation — see our breakdown of passing off in India.
When you brief any Indian trademark lawyer on a similarity fight, Amritdhara is the first case pulled up. It is cited in examination replies, opposition pleadings, and injunction hearings with equal force.
Amritdhara is not history. It is the lens every examiner reads your brand through.
Before you commit to a name, test it the way the Supreme Court would: say both marks aloud to someone who has never seen them written, a day apart, and ask what they remember. If the impressions blur, pick another name — or be ready to defend this one.
