The subject of trademarks is a distinct discipline within brand management, owing to its legislative foundations and strong academic grounding in legal studies. Accordingly, the aim of this chapter is not to provide an exhaustive treatment of trademarks from a legal perspective (as, for instance, offered by Sosnitza, 2023). Instead, it is intended to equip readers with essential knowledge of the principal aspects of trademark registration and management. The legal framework presented here is rooted in the German market but extends to encompass the European Union and the WIPO while not addressing the specifics of other national systems.
