There is a likelihood of confusion between the word mark “KNEIPP” and the contested mark “Internationale Kneipp-Aktionstage”. The finding that a name is used as a synonym for a certain method and has developed into a generic term is subject to strict requirements. As long as a relevant public still adheres to the meaning of the word as an indication of the origin of the goods or services from a particular business, such a development cannot be assumed. If a sign identical to an earlier trademark is incorporated into a later combination sign, the increased distinctiveness of the earlier trademark due to use can be taken into account when determining the distinctive elements of a later sign (BGH, decision of February 14, 2019, case reference: I ZB 34/17).
