Areas of practice

Dr Helmut Janssen specialises in antitrust law and public subsidies/state aid law. His advisory services in antitrust include, in particular, providing preventive advice (e.g. on compliance systems) and defending his clients against antitrust infringement allegations, reviewing and structuring distribution systems and cooperation agreements between competitors, and assisting with foreign and domestic merger control proceedings. In subsidies and state aid law Helmut Janssen advises on a wide range of preventive measures in public grant cases, such as drafting of entrustment acts, and defends subsidies in proceedings before German courts, the European Commission and the European Court of Justice. He advises clients in proceedings before the European Commission under the Foreign Subsidies Regulation (FSR). A further area of expertise is international trade law (WTO and EU anti-subsidy/antidumping law). Helmut Janssen has more than 20 years of experience dealing with EU institutions. Furthermore, he has authored a reference textbook on antitrust law (6th edition 2023) and numerous specialist and academic publications on antitrust and state aid/subsidies law. He is a member of the antitrust sections of the International Bar Association, the American Bar Association and of the leading German antitrust and state aid associations.

Court-approved antitrust mediator

Dr Helmut Janssen is an antitrust mediator approved by the competent German Court of Appeal. As a mediator, he specialises in the out-of-court settlement of claims arising under antitrust law, e.g. for damages, supply and injunctive relief. A procedure before an antitrust mediator offers several advantages. An agreement concluded by the parties in front of a court-approved mediator has the same effect as a state court judgment.
