Key legal question
Whether 'GIPFELTREFFEN' is descriptive and lacking distinctiveness for 'organization and arrangement of assemblies, congresses'.
Extracted holding
Yes. For those services the sign is immediately understood as a meeting of responsible persons and directly describes the nature of the services.
Extracted reasoning
The relevant public would perceive no ambiguity or fanciful meaning. Additional possible meanings do not remove the descriptive character when the primary descriptive sense is obvious.
