Court of Justice of the European Communities, C-371/06
The third indent of Article 3(1)(e) of First Council Directive 89/104/EEC of 21 December 1988 to approximate the laws of the Member States relating to trade marks is to be interpreted as meaning that the shape of a product which gives substantial value to that product cannot constitute a trade mark under Article 3(3) of that directive where, prior to the application for registration, it acquired attractiveness as a result of its recognition as a distinctive sign following advertising campaigns presenting the specific characteristics of the product in question.
