Who's Who Legal Litigation: Lawyers

A senior partner in the litigation department, Les Fagen has litigated on behalf of both plaintiffs and defendants for more than 35 years, handling his clients' most complex civil litigation matters.

Mr Fagen has a strong track record of wins and favourable settlements at the trial and appellate levels in federal and state courts in multiple jurisdictions, and in alternative dispute resolution proceedings. Some of his illustrative case work includes: representation of major private equity companies and hedge funds in substantial commercial disputes concerning transactional matters and securities litigation and regulation; representation of major public company defendants in significant securities litigations, antitrust and transactional matters and internal investigations; representation of clients in major international and domestic arbitrations, including his role as lead trial counsel for Citigroup defending a US$7.5 billion claim brought by the Abu Dhabi Investment Authority in which an arbitration panel ruled in Citigroup's favour; and representation of clients in the media, fashion and information services fields in intellectual property matters including trademark, copyright and licensing disputes.

Les's major client representations have included Citigroup Inc, JPMorgan Chase & Co, UBS, Viacom, Inc, CBS Corporation, Paramount Pictures Corporation, Metropolitan Transportation Authority, Showtime Networks Inc, Calvin Klein Inc, Michael Kors Holdings and Polo Ralph Lauren.

Les's work on behalf of ACNielsen & Co and other clients was profiled in an American Lawyer cover story, "The Lifesavers", in which Paul Weiss was selected as the best litigation firm in the United States. He is noted as a leading practitioner in commercial litigation by Chambers USA and Who's Who Legal. He has been named by his peers in The Best Lawyers in America as a leader in the fields of commercial and intellectual property litigation. He has been recognised as an "excellent trial lawyer and general counsellor" in The Legal 500 and a leading attorney in the competition and product liability litigation fields in Lawdragon 500.

Les is a fellow of the American College of Trial Lawyers.

He has served on the firm's management committee. He is a former chairman of the firm’s partnership committee and served as co-chair of the firm's litigation department.

Les is an adjunct lecturer in law at Columbia Law School, where he teaches trial advocacy, and an adjunct professor of law at Brooklyn Law School, where he teaches an intellectual property litigation course. Les is also an associate fellow at Berkeley College, Yale University.

He is a member of the Association of the Bar of the City of New York, and has served on several bar committees, including committees on the judiciary, state legislation and transportation.

Les is a director of the Lawyers' Committee for Civil Rights Under Law. He has served as president and vice chairman of the Educational Alliance, Inc, a multidisciplinary social service agency, and as a member of the board of trustees of the Maimonides Medical Center. He has been a David Rockefeller fellow at the partnership for New York City.

Les is the author of numerous publications on arbitration, intellectual property and product liability.

WWL says: Leslie Gordon Fagen is a "fantastic lawyer" and has over 35 years of experience litigating for clients, including both plaintiffs and defendants, in significant civil cases.
