A former federal prosecutor and experienced trial lawyer, Patrick focuses on representing corporations, financial institutions, board members, and executives in civil and criminal regulatory matters, internal investigations, and litigation in federal and state courts.

Patrick has extensive experience investigating and litigating matters involving allegations of corruption, including FCPA violations; financial fraud, including securities fraud, insider trading, and cryptocurrency fraud; and anticompetitive conduct, including price fixing and monopolization. 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. Patrick has also advised boards of directors and special committees overseeing government and internal investigations, as well as on governance and compliance.

Prior to returning to private practice in San Francisco, Patrick served for eight years as an Assistant U.S. Attorney in the Eastern District of New York, including most recently as Deputy Chief of the Business and Securities Fraud Section and as a senior member of the Department of Justice’s FIFA Corruption Task Force. 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.
