Questão jurídica principal
Whether the defendant's Swiss S100 mark was unprotectable under Art. 4 MSchG as an agent/authorized-user registration
Decisão extraída
Art. 4 MSchG did not apply because the parties' contractual relationship concerned only the US and Canadian market; no contractual authorization for Switzerland was established.
Fundamentação extraída
The special rule requires a contract or authorization covering the relevant territory and a duty to protect the principal's interests. Knowledge or tolerance of Swiss sales without a contractual basis was insufficient.
