Jonathan S. Tam is experienced litigator and trusted advisor who has represented major pharmaceutical companies, medical device companies, and consumer electronic companies in some of the most complex mass tort product liability litigations, consumer fraud actions, and class actions in the country, including cases filed by State Attorneys General.

He has led, managed, and handled various aspects of complex, nationwide litigations in state and federal courts, including motions to dismiss, expert discovery, summary judgment, trials, and appeals.  In particular, he has extensive experience drafting briefs concerning the admissibility of expert testimony under Daubert. He was a key member of teams that secured the dismissal of plaintiffs’ general causation testimony under Daubert and the entry of summary judgment for a pharmaceutical manufacturer in two major mass torts, and also helped draft the briefs that ultimately cemented those victories in the federal appellate courts.

Litig., 858 F.3d 787 (3d Cir. 2017). These Daubert decisions are routinely cited by courts and parties around the country

His publications include "Jury Selection in Federal Court" in Practical Law Journal and "Liability for Failure to Warn Under New York Law" in Products Liability in New York: Strategy And Practice.
