Mr. Winthrop was honored with the Artistic Freedom Award by the ACLU of Southern California for his and his colleagues' successful representation of artist Thomas Forsythe against claims of trademark and copyright infringement brought by Mattel, Inc. (Mattel, Inc. v. Walking Mountain Prods., 353 F.3d 792 (9th Cir. 2003)).

Mr. Winthrop served as law clerk to Associate Justice John Paul Stevens of the United States Supreme Court, 1992–1993, and to Judge Patricia M. Wald of the United States Court of Appeals for the District of Columbia Circuit, 1991–1992.
