Trademark law is primarily regulated in the Trademark Act, but also in the BGB and UWG, among others. At the EU level, the Trademark Directive (89/104/EEC) is particularly worth mentioning in trademark law, as is the Madrid Trademark Agreement (MMA) at the international level.
Trademark law includes the commercial protection of brands, but also, among other things, the protection of company symbols (branding), geographical indications of origin, Internet domains or names.
