“It appears from the CJEU’s judgment in Holterhoff v Freiesleben (2/00) [2002] E.C.R. I-4210, particularly when read in the light of its decision in Arsenal Football Club v Reed (C-206/01) [2002] E.C.R. I-10273, that purely descriptive use of a sign does not amount to use of a sign “in relation to” goods or services. On the other hand, it is clear from the decision of the CJEU in Gerolsteiner Brunnen GmbH & Co v Putsch GmbH (C-100/02) [2004] E.C.R. I-691that a sign may be used in relation to goods or services even though it is an indication concerning a characteristic of the goods or services (in that case, their geographical origin). In other words, it is possible in some circumstances for a sign both to be descriptive and to function as a trade mark.”
“… The comparison here is between the sign and the mark. The court must identify the sign which the defendant has actually used and the context in which he has used it; and this must be compared to a notional and fair use of the mark in relation to all of the goods and services in respect of which it is registered. The mark may or may not have been used; it may have been used in relation to some but not all of the goods or services for which it is registered; and any use may have been on a small or a large scale. But the question in every case remains the same, namely whether, having regard to a notional and fair use of the mark in relation to all of the goods or services for which it is registered and the actual use of the sign, there is a risk that the average consumer might think that the goods or services come from the same undertaking or economically linked undertakings, and that is all.”
“111. …. (i) the registered trade mark must have a reputation in the relevant territory; … (vii) it must give rise to a link between the sign and the trade mark in the mind of the average consumer; (viii) it must give rise to one of three types of injury, that is to say, (a) detriment to the distinctive character of the trade mark, (b) detriment to the repute of the trade mark, or (c) unfair advantage being taken of the distinctive character or repute of the trade mark; and (ix) it must be without due cause.”
“In summary, it is not necessary for the earlier mark to be unique, although the more “unique” it appears, the greater the likelihood that a later identical or similar mark will be detrimental to its distinctive character; secondly, the use of an identical or similar mark may suffice, in some circumstances, to cause actual and present detriment to the distinctive character of the earlier mark or to give rise to a serious likelihood that such detriment will occur in the future; and thirdly, detriment to the distinctive character of the earlier mark is caused when that marks ability to identify the goods or services for which it is registered and used as coming from the proprietor of that mark is weakened. There followed at para.[77] [of Intel] this important explanation of what is needed by way of proof: “77. It follows that proof that the use of the later mark is or would be detrimental to the distinctive character of the earlier mark requires evidence of a change in the economic behaviour of the average consumer of the goods or services for which the earlier mark was registered consequent on the use of the later mark, or a serious likelihood that such a change will occur in the future.”
