Even if it looks like a Kit Kat, it might not be.
The European Court of Justice has thrown out an appeal by the chocolate bar’s maker, Nestlé, which argued that it owns the shape of the teatime treat.
Nestlé has spent more than a decade fighting to trademark the four-fingered wafer shape – something that rival Cadbury had fought hard against.
But Wednesday’s judgement found that a previous court had been right to annul the decision by Europe’s trademark group.
That could bring an end to the snack’s protected European status – and a saga that has proved expensive for both sides.
It also takes the pressure off identical treats like Norway’s Kvikk Lunsj – pronounced “quick lunch” and which has been around for 80 years – and opens the door to own-brand imitations at your local supermarket.
