Marc E. Isserles |

Marc Isserles is an experienced litigator whose practice focuses on appellate advocacy, intellectual property litigation, complex commercial litigation, and strategic counseling.

Marc has successfully represented corporations and individuals in a wide variety of substantive areas, including copyright, trademark, right of publicity, false advertising, breach of contract, fraud, fiduciary duty, and constitutional law. Marc also regularly advises major corporations on complex civil litigation issues in the pre-litigation context, helping them evaluate their rights and/or potential legal exposure before a formal dispute has arisen, and assisting them in adopting and implementing business strategies in light of that legal analysis.

Marc is also a commercial mediator, with a particular emphasis on mediating intellectual property licensing disputes. As an advocate for clients in numerous commercial mediations, Marc came to understand that mediation, in the right case, can be a superior alternative to the traditional litigation process. Marc brings to his mediation practice a natural affinity for facilitation, compromise, and moderation, as well as the analytical and evaluative skills of an experienced civil litigator. Marc completed his basic mediation training at the New York City Bar, and commercial mediation training at the New York State Bar Association. He serves as a mediator on the mediation panels of the United States District Court for the Southern District of New York, and the Supreme Court, Commercial Division for New York County, Kings County, Westchester County, and Nassau County; and the Civil Court of New Jersey. Marc is a member of the ADR Committee of the New York City Bar Association, and a member of the New York State Bar Association’s Dispute Resolution Section.

Prior to co-founding Shapiro, Arato & Isserles LLP, Marc was a partner at a leading litigation boutique in New York City, and prior to that was an appellate and intellectual property litigator at top firms of national reputation, including Parcher Hayes & Snyder P.C. Marc is also the author of an article on “facial challenges” in constitutional adjudication that has been widely cited by courts and commentators.
