Key legal question
Whether the refusal of protection for the international trademark 'Micropor' was lawful because the sign is descriptive/common property under Art. 2 lit. a MSchG.
Extracted holding
Yes. 'Micropor' is understood in Switzerland as referring to small/fine pores and thus directly describes a characteristic of the goods.
Extracted reasoning
The word is split into 'micro' and 'por'; for filters and vacuum bags, pore structure is an immediate descriptive reference without special imaginative effort. The missing 'e' in 'pore' does not materially change the overall impression, and foreign registrations are not decisive for Swiss perception.
