Yes. The Swiss Trademark Act provides that trademark protection shall not be available to signs contrary to applicable law (art. 2 [d]). Art. 2 of the Swiss Unfair Competition Act provides that “[A]ny behaviour or business practice that is deceptive or that in any other way infringes the principle of good faith and which affects the relationship between competitors or between suppliers and customers shall be deemed unfair and unlawful”. Depending on the case at hand, other provisions of the Swiss Unfair Competition Act may also be relevant.
