Marc A. Marinaccio

Marc Marinaccio focuses on complex civil litigation, commercial litigation and products liability, with particular emphasis on the life sciences industry. Marc handles all phases of high-stakes litigation, from formulating initial litigation strategy, to managing discovery and drafting motions, to trial preparation and post-trial appellate proceedings.

Marc also represents clients in arbitration and mediation, and is frequently called upon to help clients understand and manage their risks before litigation arises.

Marc has a deep understanding of the life sciences industry, including the regulatory systems that impact all phases of a client's development and operation, supply chain structures and common business relationships in the industry, and complicated pricing, marketing and reimbursement issues relating to government healthcare programs.
