Julian F. Wienand
Dr. rer. nat., M.Sc. (Physics)
Julian brings his scientific expertise in physics, deep tech, and IT to complex patent prosecution, opposition, nullity, and patent infringement proceedings. Since 2025, he has been supporting clients in strategic patent enforcement and defense across national and European jurisdictions – working with multinational corporations and SMEs as well as startups in Europe and beyond.
Julian is a quantum physicist and published author in leading scientific journals. After having conducted research at Stanford University, he completed his doctorate at the Max Planck Institute for Quantum Optics and LMU Munich, specializing in analog quantum computing with ultracold atoms. As an experienced lecturer and speaker – including to non-technical audiences – he is specialized in distilling complex technical concepts into clear, persuasive arguments.
Through his work at the European Commission in Luxembourg, Julian also gained deep insights into the European innovation ecosystem, which greatly enhance his strategic approach to intellectual property protection.

Conducting an orchestra has taught me to listen carefully to every voice in the ensemble while keeping sight of the composition as a whole. In patent work, I apply the same approach – hearing every technical nuance while developing coherent strategies that resonate with patent offices and courts.
