Success can kill a trademark. When the public starts using your brand name for the product itself rather than as a badge of origin, the mark can become generic — and lose protection. That is genericide.
What genericide is
A trademark distinguishes one source’s goods from another’s. Genericide happens when consumers begin to associate the mark with the product category rather than its source — at which point it stops functioning as a trademark. Famous casualties: Cellophane, Escalator, Thermos and Aspirin, all once-registered marks that became everyday words.
What causes it
- Public use of the mark as the product name rather than the maker’s brand.
- First-mover products with no competitors, so the brand becomes the only word for the thing.
- Products better known by the trademark than any generic name — think Dumpster or Velcro.
How brand owners fight back
Trademark owners actively police their marks to prevent genericide:
- Pair the mark with the generic term — “Q-Tip cotton swabs,” not just “Q-Tips.”
- Use the mark as an adjective, never a noun or verb — “search on Google,” not “google it.”
- Show notices — the ® (registered) or ™ symbols.
- Send cease-and-desist notices for misuse.
- Run public campaigns — Velcro’s well-known “Don’t Say Velcro” video.
- Style the mark distinctively — a particular typeface or capitalisation.
Google, Xerox and Adobe all run programmes exactly like this.
The Indian position
Genericide is not automatic — a court must declare a mark generic. In B.V. Ilango Himachalapathy v. Rank Xerox Ltd. (2012), active policing was held to prevent a genericide declaration. In other words, an owner who visibly protects the mark can keep it, even when it is wildly popular.
Practical guidance
- Write a brand-usage guideline and enforce it internally and with partners.
- Correct third-party misuse promptly — silence is what feeds a genericide argument.
- Always give the public a generic word to use alongside your mark.
Frequently asked questions
What is trademark genericide? When a mark becomes the common name for the product itself, rather than an indicator of source, and loses trademark protection as a result.
What are examples of genericide? Escalator, Thermos, Cellophane and Aspirin — trademarks that became generic terms.
How do brand owners prevent it? By pairing the mark with a generic noun, using it as an adjective, showing ® / ™, policing misuse, and educating the public.
Does a mark become generic automatically in India? No. A court must declare it generic, and active policing (as in Ilango v. Rank Xerox) helps defeat such a claim.
