Hon. Mitchell S. Goldberg. Hon. Judge Goldberg was appointed to the United States District Court for the Eastern District of Pennsylvania on October 31, 2008.

Pa.) to assist the court with its heavy patent/IP caseload. Since that appointment, Judge Goldberg has handled approximately 100 such cases. Judge Goldberg’s career as a practicing attorney started at the Philadelphia District Attorney’s Office where he worked in both the trial and appellate divisions. He later joined and became a partner at the law firm of Cozen O’Connor, where his practice focused on commercial litigation. Judge Goldberg returned to the public sector in 1997, serving as an Assistant United States Attorney for the Eastern District of Pennsylvania where he handled mostly white collar crime cases. Judge Goldberg is a graduate of Temple Law School.
