Our People

Maucher Jenkins has built a team of outstanding professionals, recognised experts in intellectual property law, science and technology, working across multiple industry sectors and legal jurisdictions.

Dr. Katharina Brassat

Associate - Patents

German Patent Attorney

PhD in Physics, Paderborn University,
M.Sc. in Chemistry, Paderborn University



Katharina joined Maucher Jenkins in 2021 and qualified as German patent attorney in 2024. She is also working towards qualification as  European patent attorney. She holds a PhD in physics and a M.Sc. in Chemistry. Her technical fields of expertise are nanotechnology, chemistry, physics, life sciences and biotechnology.


At Maucher Jenkins, Katharina is, among other things, the contact person for partnerships with various start-up centres and accelerator programs, where she offers advice and regularly gives workshops and lectures on start-up-relevant topics relating to IP.


Currently, Katharina is a member of Women in IP which seeks to support women in intellectual property through networking events and informative seminars.


Prior to this, Katharina worked as materials scientist at Paderborn University, where she was responsible for several research projects in the areas of nanotechnology, polymer chemistry and analytical surface science. Katharina cooperated with national and international partners on interdisciplinary applied research in bionanotechnology (protein coatings, DNA origamis), semiconductor physics (nanolithography), opto-electronics (structured electrodes, quantum dots) and mechanical engineering (additive manufacturing).


Katharina actively contributed to the international research community by taking part in and organizing conferences and publishing articles in peer-reviewed journals. She led an international group of bachelor and master students and gave higher education lectures, tutorials and was distinguished for training sessions she gave on communication. She was a board member in various academic administrative units and was engaged in promoting diversity in the STEM fields. 


Interests outside work:


Katharina spends her free time with her cocker spaniel. She also enjoys visiting art museums and going to the theatre.
