Supreme Court Invalidates Post Milk Generation Mark

The UK Supreme Court has upheld the invalidity of a trade mark registration for “POST MILK GENERATION” in relation to oat-based food and drink products. The ruling confirms that the mark cannot stand because its use for such goods is prohibited by law in the United Kingdom. The decision arose in the context of broader scrutiny of marks suggesting dairy alternatives, with the court focusing on statutory restrictions rather than traditional grounds such as descriptiveness or confusion. This follows earlier proceedings before the UK Intellectual Property Office and aligns with established principles that registrations must comply with all applicable legal prohibitions on use. The outcome reinforces the registry’s approach to examining marks that risk breaching food-labelling or composition rules. While the precise timing of the Supreme Court hearing fell within the first quarter of 2026, the March 2026 IP brief highlights it as a key development for brand owners in the plant-based sector.

Small-business owners should conduct thorough legal checks on proposed marks against all relevant UK statutes before filing, to avoid later invalidity findings.
