80First, as regards the surveys relied on by the applicant, it must be held that the Board of Appeal was correct to find, in paragraph 51 of the contested decision, that those surveys were not capable of proving that the mark applied for had acquired distinctive character throughout the European Union in respect of a significant part of the relevant public. The surveys were conducted in 10 EU Member States, namely Denmark, Germany, Estonia, Greece, Spain, France, Italy, Poland, Portugal and the United Kingdom, even though the European Union had 27 Member States at the date on which the application for registration was lodged. It is true that the surveys in question concluded that the mark applied for had acquired a distinctive character in the 10 Member States where they were carried out, with the recognition rate being between 48% (Poland) and 79% (Spain); however, they did not establish that that was also the case in the other 17 Member States. The results of those surveys cannot be extrapolated to the 17 Member States in which no surveys were conducted. In that regard, it must be pointed out that, particularly in respect of the countries that became members of the European Union after 2004, the surveys provide almost no information regarding the perception of the relevant public in those Member States. Even though surveys were conducted in Poland and Estonia, there is no justification for extrapolating the conclusions relating to those two countries to the other states which became members of the European Union after 2004. Furthermore, the applicant has not demonstrated that certain Member State markets covered by the surveys are comparable to others and that the results of those surveys could be extrapolated to them. It is not for the Court to make assumptions in that regard.
