Infringement often turns on a single word — the “essential feature” of a mark. When “MAXCURE” hospitals collided with the “MAX” healthcare group, that dominant word decided it.
The dispute
Max Healthcare — part of the “MAX” group (Max Life, Max Bupa, Max Speciality Films) — holds six registered label marks bearing “MAX.” When a defendant began operating as MAXCURE / MAXKURE Hospitals, Max sued in the Delhi High Court on two questions:
- Did the defendant infringe?
- Is “MAX” an essential part of the plaintiff’s marks?
- Plaintiff: long, quality use built goodwill in MAX / MAX HEALTHCARE, creating an exclusive nexus with it.
- Defendant: no one can claim proprietorship over “MAX” alone.
What the court held
The court found “MAX” had been extensively adopted and used by the plaintiff and its group — functioning as both trademark and trade name across ventures. It concluded “MAX” was an essential feature of the plaintiff’s registered marks, and the defendant’s MAXCURE amounted to infringement.
The doctrine
- Marks are compared by their essential/dominant features — “by whatever name (label, device, composite, word) it is called.”
- When a word within a mark associates the goods with its owner, another trader adopting that word infringes.
- Deceptive similarity is assessed across visual, structural and phonetic dimensions, plus the nature of the goods/services and the purchasing public.
- The ultimate test is the likelihood of confusion in the mind of an average person — the impression the mark leaves, not a fragment-by-fragment comparison.
The takeaways
- Identify your essential feature — the word/element that carries source recognition — and register and police it. (Compare rights in the whole mark, not its parts.)
- A shared dominant word is dangerous — adopting a rival’s essential feature invites an infringement finding even if the rest differs.
- Group-wide use strengthens the claim — consistent use across ventures reinforces that the element identifies you.
Frequently asked questions
What is the “essential feature” of a trademark? The dominant, source-identifying element of a mark; courts compare marks by their essential features to decide confusion and infringement.
Can adopting one word from another’s mark infringe? Yes — where that word is the essential feature associating the goods with its owner, as “MAX” was for Max Healthcare.
How is deceptive similarity assessed? Across visual, structural and phonetic similarity, plus the nature of the goods/services and the purchasing public, judged by likely confusion.
Does registering a composite mark protect each word? No — you generally need the key word registered/used as an essential feature to enforce it, not just as part of a label.
