Areas of Focus

Overview

Ryan W. Marth advises U.S. and international clients on all aspects of their businesses, including contractual relations, distribution, pricing, protection of intellectual property, and compliance with U.S. and foreign antitrust and competition laws. He has been nationally ranked by Chambers USA in Antitrust in Minnesota since 2016.

Ryan has deep experience in complex antitrust and commercial cases. He uses that experience to help clients anticipate business challenges, spot problems before they arise, and avoid conflict and litigation—and, when conflicts do arise, to obtain favorable results. Most notably, Ryan was among the lead lawyers for a class of merchants that obtained a $5.6 billion settlement in an antitrust class action against Visa, Mastercard, and their member banks—the largest such settlement in the history of the antitrust laws.

Ryan's practice includes advising businesses that are victims of cartel or dominant-firm behavior on their remedies under U.S. and foreign competition laws, representing these businesses before state and federal courts and regulatory bodies, and collaborating with non-U.S. counsel when appropriate to help them obtain relief abroad. He also defends businesses against investigations and litigation involving accusations of anticompetitive conduct, including securing a sub-cost-of-defense settlement for a Norwegian salmon sales company accused of price fixing in nationwide class actions.

Before attending law school, Ryan lived in Norway for two years, including one year as a Fulbright Scholar at the University of Oslo studying Norway's relationship to the European Union, and he regularly uses his knowledge of Scandinavian business and government to identify and address the challenges that Nordic businesses may encounter when operating in or expanding to the United States.
