Background

About Mark Seiden

I have successfully represented clients in product liability, commercial litigation, and complex civil litigation in courts throughout the United States. Since 2010, I have served as trial counsel in more than a dozen jury trials. My representation of R.J. Reynolds Tobacco Company spans more than a decade and includes a wide variety of cases including putative class actions, third-party payor lawsuits, individual product liability cases, marketing and unfair practices claims, and alleged international money laundering. On behalf of Macy's, I led a Jones Day team that successfully opposed — both at the trial and appellate courts — a request for certification of a nationwide class of vendors pressing claims under UCC Article 2. On behalf of IBM, I successfully argued before the New York Court of Appeals that alleged soil and groundwater contamination did not constitute a material breach of a commercial lease. I have also represented IBM on a number of insurance coverage matters. In addition, I have significant experience representing asset-based lenders, including factors and A/R financiers. I am deeply committed to working on pro bono matters and serve as the New York Office's pro bono coordinator. I have developed deep experience in international child abduction matters, representing parents in Europe, South America, Mexico, and the Caribbean. I have served as practice coordinator for the office's New Lawyers Group for more than half a decade. I am an adjunct professor of law, teaching a pretrial practice seminar at Cardozo Law School.
