Kernrechtsfrage
Whether stars used for classifying accommodation facilities are protectable as trademarks
Extrahierter Entscheid
The stars belong to the public domain in this context and are excluded from trademark protection.
Extrahierte Begründung
In the hotel-classification context, stars are immediately understood as descriptive quality indicators. Because they are widely used by market participants and no equally effective alternative symbols are available, there is an absolute need to keep them free.
