Hon. Gregory M. Sleet (Ret.) joined JAMS after serving 20 years on the bench of the United States District Court for the District of Delaware, including seven years as Chief Judge. During his tenure on the District Court, he gained deep experience in a number of areas of complex commercial litigation, especially patent litigation involving pharmaceuticals and a wide variety of other technologies. Judge Sleet presided over and resolved by pretrial ruling, trial, or settlement thousands of cases involving a wide variety of subject matters, including those in the intellectual property, antitrust, bankruptcy, class action, business/commercial, pharmaceuticals/medical devices, products liability, securities and tax realms. 

Judge Sleet focuses his national practice on arbitrations, mediations, and neutral analyses (case evaluations and mock trials).

Before taking the federal bench in 1998, Judge Sleet acquired varied experience in civil and criminal litigation and corporate legal work. He served as the United States Attorney for the District of Delaware, as in-house counsel in the legal department of Hercules Incorporated, and as Deputy Attorney General handling major civil cases for the State of Delaware. Prior to that, he practiced law in Philadelphia for fourteen years, six of those as an Assistant Public Defender with the Defender Association of Philadelphia.

Judge Sleet is a frequent speaker on patent litigation. Select examples of his speaking engagements include: the Harvard Law School Conference on Intellectual Property, the Stanford University Conference on IP Law and Biosciences, the Rocky Mountain Intellectual Property and Technology Institute, the Sedona Conference, the USC Gould School of Law, the New York Intellectual Property Law Association’s (NYIPLA) symposium on patent litigation, the Practising Law Institute (PLI), and the American Conference Institute (ACI).
