Delhi High Court Declares 'CALPOL' as a Well-Known Trademark

The Delhi High Court officially recognized GlaxoSmithKline’s pain and fever medicine brand, CALPOL, as a well-known trademark under the Trade Marks Act, 1999.

Justice Jyoti Singh passed the order in an infringement suit against Walter Healthcare, which was using the deceptively similar name "WALPOL".

Although the parties settled the main dispute, the Court independently evaluated the trademark’s status.

Citing CALPOL’s continuous commercial presence for over 35 years and sales surpassing ₹300 crore in 2024 alone, the Bench ruled that the brand has achieved immense reputation and distinctiveness, granting it high-level statutory protection against prospective market copycats.
