Kernrechtsfrage
Whether the refusal to grant Swiss trademark protection for 'BahnCard' was lawful because the sign belonged to the public domain.
Extrahierter Entscheid
Yes. 'BahnCard' directly evokes a customer or credit card of a railway company and lacks distinctive character for the claimed services.
Extrahierte Begründung
The combined German-English term is immediately understood as a railway company's card. For financial services and transport services it merely describes a customer/card-based means of access or payment and does not identify a specific undertaking.
