The European Court of Justice (”ECJ”) ruled in Praktiker Bau- und Heimwerkermärkte (C 418/02) that a trade mark that is now in use by a company on its goods can be extended to cover the services provided by this company.

A DIY retailer Praktiker Märkte, filed for registration with the Deutsches Patent und Markenamt (the German Patent and Trade Mark Office) of the mark PRAKTIKER in respect of the slogan ‘retail trade in building, home improvement and gardening goods for the do-it-yourself sector.’ However the German Patent Office refused registration of this slogan on the grounds that the concept of ‘retail trade’ did not denote independent services having autonomous economic significance.
