The European Court of Justice today dismissed the appeal by Nestlé in its long-running battle with Cadbury over the shape of its KitKat chocolate bar.

The Court upheld the General Court's judgment that the acquisition of distinctive character by a mark that was initially devoid of inherent distinctive character must be shown throughout the EU, and not only in a substantial part of the territory of the EU.
