Tips for Businesses
Audit your trade mark portfolio and remove or replace any dairy terms used as product descriptors. File new trade marks using invented or benefit-driven words. Monitor opposition proceedings and engage with industry bodies shaping voluntary compliance standards.
The ‘Post Milk Generation’ trade mark is a branding dispute that clarifies the scope of dairy terminology restrictions under UK law. The UK Supreme Court’s February 2026 ruling against Oatly confirms that regulations reserving terms such as ‘milk’ for animal-derived products, retained from EU law post-Brexit and enforced by the Food Standards Agency, extend beyond product labels to trade marks and marketing materials. Dairy UK, the industry body that brought the challenge, has demonstrated that intellectual property law is now an active enforcement tool in this space. Plant-based businesses operating in the UK must review their branding, advertising and trade mark portfolios in light of this ruling.
What Should Plant-Based Businesses Do?
Businesses that manufacture or sell plant-based alternatives should review their branding, packaging, advertising and trade mark portfolios. They should ensure these materials comply with restrictions on protected dairy terminology. Marketing should clearly communicate that products are plant-based without relying on reserved terms such as ‘milk’ as product descriptors. Before using dairy terminology in branding, businesses should consider trade mark advice. Dairy industry organisations may oppose trade mark applications that reference protected dairy terms.
The UK Supreme Court’s February 2026 ruling against Oatly has sent ripples through the plant-based food and drink sector. The decision may seem narrow because it prevents one company from using a specific trade mark. However, its implications extend well beyond one brand. For plant-based businesses, this ruling clarifies the limits of acceptable marketing language. It also signals potential challenges ahead.
Understanding the Legal Landscape
The court’s decision reinforces long-standing regulations that reserve the term “milk” exclusively for dairy products derived from animals. These rules, inherited from EU law and retained post-Brexit, aim to prevent consumer confusion by maintaining clear distinctions between traditional dairy and plant-based alternatives.
However, the ruling goes beyond simple product labelling. By blocking the “Post Milk Generation” trade mark, the court has indicated that dairy terminology restrictions apply equally to marketing slogans, brand identities and advertising campaigns, and not just ingredient lists or product names.

Immediate Implications for Plant-Based Brands
Plant-based food and drink manufacturers should now scrutinise their entire marketing ecosystem. This includes:
- Trade mark portfolios: Existing and pending trade mark applications containing dairy terms may face opposition from dairy industry groups emboldened by this ruling. Brands should review their registrations and carefully consider any ongoing use of potentially risky marks.
- Advertising campaigns: Marketing materials that play on dairy terminology – even in creative or ironic contexts – may attract regulatory scrutiny or legal challenges. The Oatly ruling suggests that intent and context matter less than the literal use of protected terms.
- Packaging design: Whilst plant-based products have long navigated labelling requirements, this decision emphasises the need for clear, prominent plant-based qualifiers. Ambiguous or subtle distinctions may no longer suffice.
- Social media and digital content: Online marketing often adopts a more playful tone than traditional advertising. However, brands cannot assume that informal channels offer greater flexibility with protected terminology.
The Competitive Landscape
Dairy UK’s successful challenge demonstrates the dairy industry’s willingness to use intellectual property law as a competitive tool. Plant-based brands should anticipate further opposition proceedings and legal challenges, particularly as the alternative protein market continues to grow.
Strategic Considerations for Businesses
Forward-thinking plant-based brands should view this ruling as an opportunity to differentiate rather than simply comply. Consider:
- Distinctive branding: Rather than approximating dairy terminology, develop a unique brand language that emphasises the plant-based nature and benefits of your products. This approach avoids legal risk whilst building a distinct market identity.
- Consumer education: Invest in marketing that educates consumers about your products’ characteristics, uses and nutritional profiles. Research suggests consumers are not genuinely confused by plant-based alternatives – they simply need clear information.
- Trade mark strategy: When filing new trade mark applications, the lowest risk approach is to avoid dairy terminology entirely. Focus on invented words, plant-specific terms or benefit-driven language that cannot be challenged on these grounds.
- Industry collaboration: Engage with trade bodies and industry groups developing voluntary codes of practice. Proactive participation in standard-setting may help shape more balanced regulations.

Frequently Asked Questions
What did the UK Supreme Court rule in the Oatly case?
The court ruled against Oatly’s ‘Post Milk Generation’ trade mark, confirming that regulations reserving terms such as ‘milk’ for animal-derived products extend beyond product labels to trade marks, marketing slogans, and advertising campaigns.
Can I still use ‘milk’ anywhere on my plant-based product packaging?
You can use ‘milk’ in limited contexts, such as ‘milk-free’ or within ingredient lists to indicate the absence of dairy. However, you cannot use it as a product descriptor or in a way that suggests the product is a milk equivalent. Always pair any reference with clear plant-based qualifiers prominently displayed.
Can I use dairy terms if I clearly state the product is plant-based in the same sentence?
Generally, no. Even with qualifiers like ‘plant-based’ or ‘vegan’, using protected dairy terms as product descriptors violates the regulations. For example, ‘plant-based milk’ is not permitted, whereas ‘oat drink’ or ‘almond beverage’ is acceptable.
What trade mark strategy should plant-based businesses adopt following this ruling?
When filing new trade mark applications, avoid dairy terminology entirely. Focus on invented words, plant-specific terms, or benefit-driven language that cannot be challenged on these grounds. Existing and pending applications containing dairy terms should be reviewed for opposition risk.
