"He handles matters really professionally and the quality of the output is extremely high. His work ethic is incredible!”

IAM Patent 1000, 2016/2017

Alexander Klicznik is a patent litigator with a focus on infringement actions, oppositions and nullity actions. Being qualified both as lawyer and European Patent Attorney, Alexander focuses on matters of high technical complexity in the areas of telecommunications, mobile communications (also relating to LTE, UMTS, GSM/GPRS), data compression, pharmaceuticals, chemistry, biotech, solid state physics, computer hard and software, optical devices, and general mechanics.

Having focused on patents since 1999 Alexander had exposure to numerous cases and regularly represents clients before patent infringement venues in Dusseldorf, Munich and Mannheim, before the Federal Patent Court, the European Patent Office and the Federal Supreme Court. Alexander is one of the few double-qualified attorneys/patent attorneys in Germany who is recommended for both infringement actions and nullity actions (IAM Patent 1000 2018/2019). In addition to litigation, Alexander handles FTO reports and analyzes patent portfolios also encompassing several jurisdictions.

Furthermore, Alexander is a lecturer at the LL.M. program of the University of Dusseldorf (nullity and opposition, also proceedings at the future Unified Patent Court). Prior to joining Hogan Lovells, Alexander worked for the Max Planck Institute for Intellectual Property in Munich. For his Ph.D. thesis, Alexander was awarded the prize of the faculty of law of Ludwig Maximilians University Munich. Before his admission to the bar in 2004, Alexander trained with the Federal Patent Court and the patent infringement chamber of the Munich District court. 

During his physics studies, Alexander dealt with magnetic scanning microscopy on thin films, NMR spectroscopy and the programming of software for analyzing a large amount of data in the context of an experiment aimed at determining the magnetic form factor of the neutron.
