Science and
legal practice
I have studied law in Munich, Geneva and Austin (Texas). The University of Texas has awarded me the degree of Master of Comparative Jurisprudence. I have received a doctorate from the Ludwig-Maximilians-Universität in Munich for a dissertation on international antitrust law.
My career started as an attorney-at-law in New York. Subsequently, I worked as a German Rechtsanwalt in corporate law firms in Munich and Hamburg where I focused on litigation, in particular in the field of intellectual property, and on antitrust law. Before I was elevated to the Supreme Court bar I was a partner in a leading international law firm for 13 years, and head of their Hamburg office and member of the German management.
I have been admitted to the Supreme Court bar since 2014. In addition to my appellate work before the Supreme Court I also serve as a legal expert witness and as arbitrator.
During my whole career I have also been active in academic research and teaching. I have published numerous articles and books and was one of the editors of the leading work on the German Trademark Act. I have been a lecturer in law at the Friedrich-Schiller-University in Jena and the Technical University Hamburg-Harburg that has made me an adjunct professor for patent law in 2003. In addition, I have lectured in numerous courses and seminars.
Selected
Reference cases
Judgment of Max 25, 2025 – XII ZB 395/24
The Federal Supreme Court upholds the decison of the Court of Appeals that I defended. He decides on the permissible content of nuptial agreements involving business owners, in particular with respect to the exclusion or limitation of the spouse's rights.
Judgment of March 13, 2025 – IX ZR 201/23
The Federal Supreme Court ruled on significant issues concerning claims for damages resulting from preliminary injuctions that were later revoked, especially with regard to the calculation of such damages. The judgment followed the arguments I submitted on behalf of the defendant in substanital parts.
Order of September 27, 2022 – KZB 75/21
In this groundbreaking order the Federal Supreme Court decides that arbitral awards are subject to unlimited judicial control as far as they are based on antitrust law. The arbitral award that had been unfavorable to my client is therefore mostly vacated.
Competence and cooperation
My approach is informed by my long experience as a trial attorney and my academic rigor. It is focused on the specific case and my client's objectives. I consider details, engage with academic controversies and take no shortcuts. I look for the decisive point and a creative solution.
Successful litigation is based on teamwork. I cooperate closely with the client's external and in-house attorneys and other team members. Of course, I am open to discussing my draft briefs and am happy to participate in meetings. If the client desires, I will also advise on litigation pending in the lower courts or in anticipation of impending cases.
At every stage of the case I provide clear assessments and recommendations. The necessary steps result from this analysis. Decisions are made jointly but the ultimate responsibility for the conduct of the litigation always rests with me.
