Rüdiger Lahme is the Managing Partner of our Hamburg office. He specialises in national and international civil litigation, often with an antitrust background.

Rüdiger has extensive experience in handling complex disputes at all levels of judicial proceedings, from pre-trial strategy advice to the highest instances. His broad courtroom expertise stems from his track record of appearances before almost all German district and appellate courts.

Rüdiger has been dealing with actions for damages with antitrust background for almost 20 years. Initially in the context of his dissertation on the suitability of German civil proceedings for private antitrust enforcement, which he authored as an assistant to Prof. Dr. Dr. h.c. Ulrich Immenga at the University of Göttingen. Ever since, he has remained engaged with the subject and has been involved in some of the largest proceedings in Germany. He regularly contributes to the relevant journals (NZKart, WuW and ZWeR), is co-author of the standard work "Kartellverfahren und Kartellprozess" from Beck Verlag (2017, new edition currently in progress) and editor and author of the procedural chapters of the practitioner's handbook "Kartellrechtliche Schadensersatzklagen" from Deutscher Fachverlag, Fachmedien Recht und Wirtschaft, 2nd edition (2022). Rüdiger is also the founding chairman of the Competition Litigation Forum (, the largest association in Germany dedicated solely to civil antitrust law. 

Rüdiger Lahme is regularly singled out in legal rankings. Germany's leading ranking, the JUVE Handbuch (Handbook), consistently ranks him as "often recommended" for conflict resolution, saying he is "one of Germany's best antitrust litigators" (Handbook 2021/2022), an "extremely clever strategist in antitrust litigation" (Handbook 2020/2021) and he and his team are praised as "exceptionally committed, hands-on and knowledgeable" (Handbook 2022/2023). The Handelsblatt Research Institute named him one of Germany's "most renowned" litigation lawyers in the Wirtschaftswoche Ranking 2022 after surveying more than 1650 lawyers from 146 law firms. In the Who's Who Legal Commercial Litigation Report 2022, Rüdiger Lahme is "singled out by peers as a "brilliant litigator" who "fights fierce and smart," particularly when it comes to antitrust cases." GCR has consistently recognized him and Who's Who Legal as a "Future Leader Competition" since 2018 and a "Leading Lawyer Competition" since 2022. In 2023, Who’s Who Legal ranked Rüdiger as a National Leader in Competition litigation in Germany.  Handelsblatt has consistently included him in its listing of Germany’s Best Lawyers for Antitrust and Competition Law, International Arbitration, and Dispute Resolution in Germany since 2019. Legal 500 summarises in its 2022 rankings for Germany: "Quinn Emanuel Urquhart & Sullivan, LLP's antitrust practice let by Rüdiger Lahme, demonstrates particularly strengths in major cartel proceedings, where it acts for both defendants and claimants."

Prior to joining Quinn Emanuel, Rüdiger was an attorney in the Hamburg and Brussels offices of Latham & Watkins LLP.

In addition to his work as a lawyer, Rüdiger Lahme is a Professor of Business Law at the Private University of Applied Sciences Göttingen (PFH) and a lecturer for the LL.M. Competition and Regulation at Leuphana University Lüneburg.
