Joseph G. Petrosinelli

Joseph G. Petrosinelli is a distinguished litigation partner and the Chairman of Williams & Connolly LLP, where he also serves on the firm's Executive Committee and co-chairs its Products Liability practice group. While his broader practice encompasses civil and criminal litigation, including products liability, mass tort/class action, and complex commercial disputes, he also handles patent litigation matters. He has been with Williams & Connolly since 1991.

In patent litigation, Mr. Petrosinelli primarily represents plaintiffs, as evidenced by his role as lead counsel for Motive Technologies, Inc. in its dispute with Samsara, Inc. This case involves technology patents related to connected fleet management solutions, including AI dashcams, machine vision, and event detection systems.

A notable outcome in the Motive Technologies, Inc. v. Samsara, Inc. litigation includes a victory for Motive in an investigation by the U.S. International Trade Commission (ITC), where Motive was cleared of infringing Samsara's patents concerning in-cab technology. Motive is also pursuing its own intellectual property theft and false advertising claims against Samsara in U.S. District Court for the Northern District of California. While he is active in federal and state courts, publicly available information does not readily indicate regular appearances in PTAB or IPR proceedings.

Mr. Petrosinelli earned his A.B. from Brown University and his J.D., magna cum laude, from Georgetown University Law Center in 1991. He has been licensed in Washington D.C. since 1992.
