Mr. Silver, a Fellow of both the American College of Trial Lawyers and the International Academy of Trial Lawyers, is best known as a go-to trial lawyer who can and will take any matter into a courtroom. In addition to handling his caseload, he is regularly asked to teach on trial-related issues. He is also widely known for his often-high-profile pro bono cases, which have included several capital and non-capital homicide cases.

Mr. Silver has tried to verdict a variety of cases; he concentrates on representing global manufacturers of products in litigation and product safety matters. He has litigated disputes about intellectual property, healthcare, securities, banking and insurance coverage and more. He has also litigated restrictive covenants and theft of trade secrets claims in the context of departing employees. He has extensive experience representing members of the equestrian sport in a wide variety of matters, including defending them against charges brought by the sport’s governing bodies.

Mr. Silver is committed to pro bono work and capital case representation in particular. His accomplishments include successful retrials of two separate death-condemned inmates before juries, both cases resulting in unanimous verdicts for the defense. In its piece on the Anthony Wright case, Rolling Stone called Sam a “powerhouse trial attorney.”

His work also includes serving as an adjunct faculty member of the University of Pennsylvania Law School, and teaching trial advocacy and other courses for the National Institute of Trial Advocacy (NITA).


Product Liability

Mr. Silver has litigated matters concerning products as diverse as heavy industrial machinery, pharmaceuticals and food supplements and also has tried multiple product liability cases and handled multiple nationwide recalls ranging from automotive parts to recreational products and toys. He has been involved extensively in mass tort product liability litigation.

Equine/Sports Law

He has represented serious equestrians in all manner of disputes concerning their sport and business. He also serves on the planning committee and is a frequent speaker at the National Conference on Equine Law.

  • He has defended several members of the profession in disciplinary hearings before the governing body of the equestrian sport in the United States, as well as before the international Court of Arbitration for Sport (CAS);
  • He defended an international horse trader against fraud and related claims associated with the purchase and sale of horses and the management of horse farm operations;
  • He has handled multiple matters (some in the courts, others before litigation ensued) stemming from disagreements over the terms and conditions of sales of valuable show horses;
  • He regularly advises equestrians concerning their business operations and contracts.

Intellectual Property

Mr. Silver has handled a broad array of intellectual property cases involving trademarks, trade secrets and claims of patent infringement. These cases have included:

  • A dispute between an internationally-known celebrity and her former business partners, whom Sam defended;
  • The defense of a university professor accused of misappropriating trade secrets from a private company; and
  • The prosecution of claims on behalf of a manufacturer of a product used by the military against an alleged infringer of that product.

Pro Bono & Civil Rights Matters

  • He defended Anthony Wright, the Innocence Project’s first client to be forced through a retrial despite having exonerating DNA evidence on his side. Mr. Wright is now a free man after spending 25 years in prison as a result of a wrongful conviction.
  • He successfully obtained a full acquittal on murder charges brought against the Firm’s pro bono client William J. Barnes. Barnes was charged with causing the death of Philadelphia Police Officer Walter T. Barclay in 2007, 41 years after Barnes had shot and partially paralyzed Barclay. Sam discussed the case on The Michael Smerconish Show, a nationally syndicated news and talk show on Philadelphia’s CBS Radio affiliate, 1210 AM WPHT.
  • He has challenged himself and others at our Firm by repeatedly leading teams of trial lawyers in successful attacks on death sentences. Twice, these teams have persuaded courts to vacate death sentences imposed by juries and to grant retrials, and in both cases, with Sam as lead trial counsel, these teams have obtained unanimous verdicts in favor of our clients when they have gone before new juries.
  • In addition, for more than a decade Mr. Silver has been a coordinator of the Prisoner Civil Rights Panel for the U.S. District Court for the Eastern District of Pennsylvania; and, at the request of the court, Sam participated in the Third Circuit’s Task Force on Counsel for Indigent Litigants in Civil Cases.
  • He discussed his experiences in capital cases on “One on One with Steve Adubato” on CN8, The Comcast Network.
