“50 […]Article 5(2) of Directive 89/104 must be interpreted as meaning that the taking of unfair advantage of the distinctive character or the repute of a mark, within the meaning of that provision, does not require that there be a likelihood of confusion or a likelihood of detriment to the distinctive character or the repute of the mark or, more generally, to its proprietor. The advantage arising from the use by a third party of a sign similar to a mark with a reputation is an advantage taken unfairly by that third party of the distinctive character or the repute of the mark where that party seeks by that use to ride on the coat-tails of the mark with a reputation in order to benefit from the power of attraction, the reputation and the prestige of that mark and to exploit, without paying any financial compensation, the marketing effort expended by the proprietor of the mark in order to create and maintain the mark’s image.”
