Patents protect innovations in the technical field, and as our technical capabilities continue to evolve, patent law becomes increasingly relevant. Originally designed for traditional areas of engineering, it now extends into modern biotechnology and the patent protection of software. This book aims to present patent and utility model law in an accessible way for non-experts. It is intended for students who are studying law as a minor, as well as for business practitioners and anyone interested in patent law. The goal of this book is to illustrate patent law, accompanied by a potentially critical discussion of invention protection in its current form. The volume also includes tips for examining patent law aspects.
