39The applicant claims that the Board of Appeal made an error of assessment, in the contested decision, in concluding that, as a result of the element ‘mac’ in the contested mark, the relevant public could associate that trade mark with the ‘Mc’ family of trade marks, from the McDONALD’S trade mark. It considers, in that regard, that the case-law concerning the family of marks must be strictly interpreted, as it derogates from the general principle that any trade mark must be assessed globally. According to the applicant, the documents placed by the intervener on the case-file relating to the proceedings before EUIPO, namely menus from the intervener’s fast-food restaurants, an independent survey carried out in 1991 and in 1992 and the decisions of courts of the Member States, were insufficient to conclude that the prefix ‘mc’ was associated, on the part of the relevant public, with foodstuffs and beverages. Except for a document referring to the McDONALD’s trade mark, those documents all dated from 2010 and, therefore, after 13 October 2008, the date on which the application for registration of the contested trade mark was filed. Furthermore, it is claimed, the part of the independent survey carried out in 1991 reveals only that the persons surveyed would associate the prefix ‘mc’ with the McDONALD’S trade mark, while the part of that survey carried out in 1992, the results of which could have been distorted by a biased drafting of the question posed, only makes it possible to conclude that most of the persons surveyed knew that the prefix ‘mc’, combined with other words, was used in relation to fast-food or self-service restaurant services. According to the applicant, the Board of Appeal was not justified in suggesting that the conclusions of the independent survey continued to be relevant more than 16 years later, and that they were even more relevant. Lastly, the decisions of courts of the Member States examined by the Board of Appeal are not, it is claimed, convincing, since they are not binding on EUIPO and relate to specific situations. The applicant states that it is clear, by implication, from the case-law and from Part C, Section 2, Chapter 7, paragraph 2, p. 4 of the directives concerning proceedings before EUIPO (‘the EUIPO directives’) that the concept of a family of trade marks is not applicable in the present case, in so far as the element ‘mac’ in the contested trade mark is not identical to the element ‘mc’, common to the ‘Mc’ family of trade marks. The element ‘coffee’ in the contested trade mark and which refers to the name of a beverage, differentiates that trade mark from the intervener’s earlier trade marks combining the prefix ‘mc’ with the name of a menu item or a foodstuff, written principally in lower-case letters. The applicant relies on the fact that, within the European Union, the intervener does not sell beverages under a trade mark including the prefix ‘mc’. According to the applicant, the differences which exist between the contested trade mark and the intervener’s earlier trade marks are sufficiently significant to be perceived by the relevant public.
60As the Board of Appeal rightly pointed out in paragraph 59 of the contested decision, the findings thus made by the national courts were, furthermore, supported by the independent survey carried out in 1991 and 1992, from which it is apparent that, in the mind of the relevant public, the prefix ‘mc’ was largely associated with the sign McDONALD’S and that that prefix, combined with another word, was widely associated with fast-food establishments belonging to the same group. According to the case-law cited in paragraph 55 above, those elements, prior to the relevant periods, could be used by the Board of Appeal. As regards the questions raised in the independent survey, it should be noted, contrary to what the applicant claims, that their formulation made it possible to verify, objectively, to what extent, in the mind of the relevant public, namely the German consumer of fast-food services, the prefix ‘mc’ was associated, on the one hand, with the sign McDONALD’S and, on the other, with fast-food restaurant services belonging to the same group. As regards the specific time frame of those results, it must be held that they do not make it possible to make links between the use of the McDONALD’S trade mark and the earlier marks McMUFFIN, McRIB, McFLURRY, CHICKEN McNUGGETS, McCHICKEN and EGG McMUFFIN, the actual use of which was found in paragraph 58 above. Those marks were, moreover, all registered after the period covered by the independent survey. However, those results support the fact that, at the time when those marks were used, the prefix ‘mc’, combined with another word, had already acquired its own distinctive character in relation to fast-food restaurant services. As EUIPO rightly observed, there is no reason to conclude, in the circumstances of this case, that the findings made in the context of the independent survey had been subsequently invalidated, since, as the Board of Appeal noted in paragraph 86 of the contested decision, the evidence produced by the intervener demonstrates that, during the relevant periods, the intervener continued to register trade marks combining the prefix ‘mc’ with another word and that the McDONALD’S trade mark has remained one of the most important trade marks in the world. That proves that the intervener continued to invest to preserve the reputation of that mark for fast-food restaurant services.
