Questão jurídica principal
Whether trademark CH P-512 831 was used in a manner preserving rights under Art. 11 MSchG
Decisão extraída
No. The use of M-WATCH alone and the version with the Swiss cross materially altered the mark's distinctive character; the mark was not used in a rights-preserving form.
Fundamentação extraída
The circle element was essential to the combined mark because the word elements were weakly distinctive. Replacing it with a hyphen or with a Swiss cross changed the overall impression; the Swiss cross was not a mere decoration.
