Court of Justice of the European Communities, C-533/06
1. Article 5(1) and (2) of First Council Directive 89/104/EEC of 21 December 1988 to approximate the laws of the Member States relating to trade marks and Article 3a(1) of Council Directive 84/450/EEC of 10 September 1984 concerning misleading and comparative advertising, as amended by Directive 97/55/EC of the European Parliament and of the Council of 6 October 1997, must be interpreted to the effect that the proprietor of a registered trade mark is not entitled to prevent the use by a third party of a sign identical with, or similar to, his mark, in a comparative advertisement which satisfies all the conditions, laid down in Article 3a(1) of Directive 84/450, under which comparative advertising is permitted.
However, where the conditions required in Article 5(1)(b) of Directive 89/104 to prevent the use of a sign identical with, or similar to, a registered trade mark are met, a comparative advertisement in which that sign is used cannot satisfy the condition, laid down in Article 3a(1)(d) of Directive 84/450, as amended by Directive 97/55, under which comparative advertising is permitted.
2. Article 5(1)(b) of Directive 89/104 is to be interpreted as meaning that the proprietor of a registered trade mark is not entitled to prevent the use by a third party, in a comparative advertisement, of a sign similar to that mark in relation to goods or services identical with, or similar to, those for which that mark was registered where such use does not give rise to a likelihood of confusion on the part of the public, and that is so irrespective of whether or not the comparative advertisement satisfies all the conditions laid down in Article 3a of Directive 84/450, as amended by Directive 97/55, under which comparative advertising is permitted.
