Dr. Andreas Groehn’s practice focuses on antitrust and intellectual property, as well as strategy issues in network industries.

Dr. Groehn provides strategic advice and expert analysis in legal proceedings. He often combines client data with public statistics and data collected through surveys to answer pressing business questions. Dr. Groehn has assessed economic damages in class actions and collective action cases in the United States, Canada, Australia, and the United Kingdom. He regularly conducts conjoint analyses in false advertising, product-defect, and intellectual property litigation. Much of his academic research focuses on network industries and two-sided markets and the economic rationale for bundling, foreclosure, and predation.

In the field of antitrust, Dr. Groehn regularly advises governmental and corporate clients in merger, abuse of dominance, state aid, and cartel cases before the Federal Trade Commission (FTC), Department of Justice, European Commission (EC), and other national antitrust authorities, as well as parties in private litigation. He has advised clients in major cartel investigations and follow-on litigation cases in Europe and class-action cases in the United States, including air cargo, financial services, hydrogen peroxide, retail, synthetic rubber, and plasterboard; and has been appointed as expert in court proceedings related to follow-on claims in the United Kingdom. He regularly estimates damages in the context of antitrust litigations, antidumping litigation, intellectual property litigation, and other commercial disputes.

Dr. Groehn has monitored compliance with structural and behavioral commitments in the chemical, medical devices, and consumer retail industries as trustee/monitor on behalf of the EC and FTC and has published on antitrust and intangible property issues. In addition, he advises clients in proceedings before the International Trade Commission and national courts in Europe and the United States and in the regulatory approval process before the US Food and Drug Administration. He regularly conducts economic and environmental impact assessments of policy measures and investment projects.

Dr. Groehn has worked out of Brussels, Frankfurt, London, and Washington, DC and has advised clients in North America, Europe, the Middle East, Africa, and Australia.
