Key legal question
Whether the non-use grace period under Art. 12(1) MSchG was suspended by foreign opposition proceedings against the base mark.
Extracted holding
Foreign opposition proceedings comparable to the Swiss opposition procedure can constitute a important reason for non-use, but the grace period does not generally wait for foreign proceedings merely because they concern the base mark.
Extracted reasoning
The court held that Art. 12(1) MSchG refers to the Swiss opposition procedure; however, serious foreign legal attacks on the base mark may temporarily make use unreasonable and thus qualify as an important reason for non-use during the period of genuine pendency.
