Mark Fiore has a diverse civil litigation practice, with a focus on business and consumer disputes, mass torts, class actions, and crisis management. An accomplished trial lawyer, he has experience with some of the largest and most complex civil cases in recent US history. He is well versed in a broad array of issues facing clients in the manufacturing, pharmaceutical, financial services, and healthcare industries, including fraud, false claims, public nuisance, products liability, consumer protection, unfair competition, tax, contract, insurance, and environmental-based claims.
Most recently, Mark served as litigation and trial counsel representing publicly traded pharmaceutical manufacturers in several high-profile trials brought by state attorneys general seeking billions of dollars in damages and abatement for public nuisance and consumer protection claims in connection with the nationwide opioid litigation. Mark was one of three trial lawyers leading the defense in a seven-month jury trial in New York state court, followed immediately by a two-month bench trial in West Virginia state court.
Mark was also a member of the trial team in a bench trial in Orange County, California, in which the team achieved the only complete defense verdict in the nationwide opioid litigation. In addition, Mark also served as lead litigation counsel for defense of claims for the Track 1 trial in the federal opioid multidistrict litigation (MDL) in the US District Court for the Northern District of Ohio and for claims brought in Oklahoma state court. The federal judge overseeing the opioid MDL called it “perhaps the most complex constellation of cases that have ever been filed” in the United States. Both of those cases were settled on the eve of multimonth trials.
Mark previously clerked with the Grand Jury and Major Crimes units of the Pennsylvania Office of Attorney General. While in law school, he won the Rutgers Law mock trial competition and served as a member of the Rutgers National Trial Advocacy Team. His pro bono practice focuses on assisting United States military veterans through the Military Assistance Project and representing indigent criminal defendants in state court proceedings.
