Aaron H. Marks is an accomplished trial lawyer focusing on complex commercial litigation.  He is widely recognized as one of the top litigators in the country, including in the most recent editions of Chambers USA: America’s Leading Lawyers for Business ("brilliant and analytical - a real star at the firm," "excellent tactician," "very effective and well prepared," "very understanding and sensitive to the needs of in-house counsel"); Legal 500 (recognized as one of the 45 Leading Trial Lawyers in the U.S.; a leading Trade Secrets attorney);  Euromoney, Benchmark Litigation: The Definitive Guide to America’s Leading Firms and Attorneys; and New York Super Lawyers 2008-2016.  Aaron was profiled as one of the nation’s most accomplished litigators under the age of 45 by The American Lawyer magazine (see related “Fab Fifty” article).  He was also one of the firm’s attorneys featured in The American Lawyer cover story chronicling the firm’s “Fast Rise to the Top.”

Aaron's practice focuses on disputes relating to securities, financial products, real estate, entertainment, mass torts and trade secrets.  He represents corporations, private equity and other investment firms, multi-national financial institutions and individuals in state and federal courts throughout the country, before arbitration panels, and in proceedings involving the Securities and Exchange Commission, the U.S. Department of Justice and various states’ attorneys general.

Aaron has extensive trial experience, including having served as first chair representing companies in several significant cases.  For example, he led cigarette manufacturer Liggett Group's defense of the nine-month trial of the Department of Justice's RICO lawsuit against the tobacco industry.  Federal District Judge Kessler issued a lengthy decision awarding judgment in favor of Liggett (whereas substantial relief was ordered against all of the other major cigarette manufacturers).  Aaron, together with other firm partners, also defended The Port Authority of New York and New Jersey in the trial concerning the Port Authority's liability for the 1993 World Trade Center bombing.
