Dr.-Ing. Stefan Neumann

Dr. Stefan Neumann has been a patent attorney trainee at the law firm Wallinger Ricker Schlotter Tostmann since December 2023. Before starting his career in the field of intellectual property, Dr. Neumann completed his doctorate in Freiberg with a focus on the characterization of various nanomaterials, in particular by means of transmission electron microscopy. Based on his experience gained in research, Dr. Neumann is particularly involved in drafting patent and utility model applications and conducting patent grant, opposition and utility model cancellation proceedings before the German and European Patent Office as well as conducting patent searches and monitoring third-party property rights.

Dr. Neumann completed his studies in materials science and materials technology at the TU Bergakademie Freiberg based on an interdisciplinary foundation course in general physics and chemistry, mechanics, electrical engineering and materials testing with a subsequent focus on solid state physics, crystallography and materials characterization. During his studies, Dr. Neumann spent a semester abroad at Akita University in Japan. From 2017 to 2023, Dr. Neumann worked as a research associate at the Institute of Materials Science at TU Bergakademie Freiberg, where he received his doctorate with “summa cum laude” for his thesis on the statistical quantification of atomic-scale properties of various nanomaterials based on correlative multiscale transmission electron microscopy.
