Nestle v Mondelez
A rivalry between two confectionery groups that tested how far a product shape can be owned as a trademark.
The parties and the question
Nestle and Mondelez compete in the same chocolate categories. The dispute asked whether a familiar bar shape could serve as a badge of origin rather than a practical feature of the product.
How the dispute unfolded
The case moved through several stages, each narrowing the argument.
- Step 01
Registration claim
One party held a registration for the three-dimensional shape and relied on it to stop sales of look-alike products.
- Step 02
Opposition and counter-claim
The other party argued the shape was technical, common in the market, and therefore not distinctive enough to monopolise.
- Step 03
Evidence on perception
Surveys, sales data and advertising history were used to show how buyers actually recognise the product.
- Step 04
Practical outcome
The result showed that a shape mark stands or falls on its own evidence, and that a famous product does not automatically earn broad protection.
Key points from the case
- Distinctiveness is judged against the way consumers see the product in the market.
- Shapes that give a technical advantage can be excluded from registration.
- Sales history and advertising can support a claim of acquired distinctiveness.
- Rival traders may still use descriptive or functional elements that are not exclusively owned.
What the parties learned
Both sides gained a clearer view of their evidence needs. Brand owners now plan shape filings with use records and consumer research prepared in advance.
Why it still matters
The dispute shows that a shape can be a valuable asset, but only when the owner can prove it identifies a single source.
