Unboxing Tetra Pak: General Court Declares Iconic Carton Shape Invalid

Key Takeaways

• General Court invalidated Tetra's 3‑D trademark for functional carton shape
• Shape's reduced material and improved handling deemed technical results under Art. 7(1)(e)(ii)
• Technical benefits to intermediaries and consumers suffice; innovation not required
• Marketing claims of lighter weight reinforced functional nature, harming trademark protection

Pulse Analysis

The European Union’s trade‑mark framework has long distinguished between brand identifiers and functional product features. Article 7(1)(e)(ii) of the EU Trade‑Mark Regulation expressly bars registration of signs that give a product a technical result, preventing trademark law from encroaching on the domain of patents and design rights. The General Court’s recent ruling provides a concrete test: identify the essential characteristics of the mark and assess whether each delivers a technical function, regardless of novelty.

In the Tetra Laval case, the octagonal carton’s four essential features—truncated angles, narrowed walls, a sealing fin and corner flaps—were shown to lower material consumption, improve stability and facilitate handling. The court held that these benefits, highlighted in Tetra’s own marketing, are technical results that directly affect the product’s performance for food‑stuff intermediaries and end‑users. By rejecting the Board of Appeal’s view that such advantages were merely commercial, the judgment affirms that functional efficiency, even when widely known, triggers the functionality bar.

Practically, the decision forces packaging innovators to reassess their IP strategy. Companies can no longer rely on trademark protection for shape‑based advantages; they must secure patents for novel technical solutions or register designs that lack functional effect. Moreover, marketing language that foregrounds technical benefits may be used as evidence of functionality, jeopardizing trademark claims. As EU courts continue to refine the functional‑feature doctrine, businesses should conduct early IP audits to separate brand elements from product engineering, ensuring robust protection without overstepping legal limits.
