He has represented companies and individuals in investigations led by the U.S. Department of Justice, the SEC, and the CFTC, and in complex civil and antitrust litigation in federal and state courts in California.

During his time at the EDNY, Patrick investigated, prosecuted, and tried a wide range of high-profile white collar criminal matters, including the FIFA corruption case, FCPA cases, and securities fraud cases.

Before joining the EDNY, Patrick clerked for U.S. District Judge J. Frederick Motz of the District of Maryland and practiced at another global law firm in San Francisco.
