In one of the most significant rulings in recent years, providing definitive clarity regarding the protection of dairy terms in the United Kingdom, the Supreme Court dismissed the appeal brought by Swedish oat drink manufacturer, Oatly AB. This ruling upholds the invalidation of the trademark for the phrase “Post Milk Generation.” The decision, made on February 11, 2026, represents a major victory for the trade association representing the British dairy industry – Dairy UK. This organization successfully argued before the court that the term “milk” is legally reserved exclusively for products of animal origin. The trademark dispute involving Oatly clearly demonstrates how strictly regulatory bodies are currently approaching official naming conventions in the food market.
The entire legal case was based on the provisions of the British Trade Marks Act of 1994. According to its provisions, the registration of a trademark is prohibited if its use is inconsistent with any applicable law. At the heart of this dispute was an EU regulation, which after Brexit was directly incorporated into British law. This act strictly protects dairy terms, such as milk, cheese, or yogurt. According to these regulations, the term “milk” is reserved exclusively for the secretion of the mammary glands of animals. The lawyers of both sides fought before the judges over the interpretation of the word “designation.” Oatly sought a very narrow interpretation, arguing that the restriction should apply only to the specific name of a food or beverage. The Swedish plant-based beverage brand argued that since the disputed phrase is only a slogan and not the name of the product itself, it should not be subject to this prohibition.
The Supreme Court unanimously rejected the Swedish company’s viewpoint, opting for a much broader interpretation of the term “designation.” The judges ruled that the prohibition applies whenever protected dairy terms are used in relation to products that do not fall within the definition of dairy, regardless of whether they serve as an official product name. This means that the word “milk” cannot be included in trademarks for any non-animal product. With the main argument falling apart, Oatly presented a secondary argument. It claimed that the phrase fell under a statutory exception that allows the use of protected terms if they clearly describe a characteristic feature of the product. The manufacturer argued that the disputed trademark was a clear indication of the milk-free nature of the oat-based beverage. This argument was also quickly dismissed.
Legal experts and patent attorneys note that this decision was driven more by strict regulatory policy than by standard trademark law principles. The ruling did not directly rely on protecting consumers from being misled, but rather on establishing fair competitive conditions through strict protection of dairy-related terms. This ruling creates a clear disconnect between intellectual property law and modern consumer behavior. The consequences for Oatly and the broader plant-based product sector are significant:
– The Swedish company must completely cease using this phrase in commerce.
– The restriction applies not only to the trademark register itself but also to labels, advertising materials, and public relations.
– The dairy industry has gained a powerful tool to block future trademarks in the plant-based sector.
