Key legal question
Whether 'Champ' is barred by the Treaty on the protection of 'Champagne' as an absolute protected geographical indication.
Extracted holding
Yes. 'Champagne' enjoys absolute protection as the name of a historical French province, and 'Champ' is confusingly similar in French-speaking consumer perception.
Extracted reasoning
The treaty grants absolute protection to the protected name for all goods; 'Champ' is commonly understood as an abbreviation of 'Champagne' in French-speaking Switzerland, so the sign conflicts with the treaty and thus with applicable law.
