This textbook provides the reader with an overview of the most important intellectual property rights and presents individual topics such as creation, transferability, enforcement, etc., for all rights collectively. This approach enhances the understanding of overarching principles and the perspective on the overall system. Since, in practice, products are often protected by multiple rights simultaneously, this representation increases practical applicability. Sönke Ahrens offers guidance for protecting one's own intellectual achievements and conveys the necessary awareness to avoid infringing on third-party rights. This is achieved not by presenting as many details as possible, but by conveying the fundamentals, legislative intentions, and legal structures, illustrated with selected practical cases.
