Since 2020, Patrick J. Kaatz has been working as a lawyer at TIGGES Rechtsanwälte, where he combines his two main areas of focus - intellectual property and antitrust law. He advises small and medium-sized enterprises as well as start-ups on all aspects of intellectual property rights, competition law, and antitrust compliance.
