Patrick has more than a decade of experience representing U.S.-based and international corporations, audit committees, banks, individuals, and the government in corporate criminal investigations. His practice is focused on white collar criminal defense, internal investigations, and risk assessment in the anti-corruption and sanctions spaces.

Patrick regularly leads internal investigations for multinational corporations in Asia. Much of his work has focused on the unique challenges facing multinational corporations with operations in China and Southeast Asia in the context of FCPA, OFAC, AML and BIS compliance.

Patrick has also represented a number of individuals based in Asia who were the subject of inquiries from United States Attorneys’ Offices, the SEC, CFTC and other regulators in the United States. 

Patrick served as a federal prosecutor in the U.S. Attorney’s Office for the Eastern District of New York from 2007 to August 2014, and was appointed Deputy Chief of the General Crimes Section in 2013. In that role, he supervised prosecutors conducting investigations, hearings, trials and appeals, and served as lead prosecutor in a case convicting a CEO with commercial bribery, FCPA violations and tax evasion. As an Assistant U.S. Attorney for the Eastern District from 2007 through 2012, Patrick investigated and prosecuted individuals and organizations in connection with the 2008 economic collapse. He handled numerous cases involving the FCPA, OFAC regulations, the mail, wire and securities fraud statutes, the Travel Act, money laundering statutes, the Lacey Act, and the Bank Secrecy Act. In recognition of his achievements at the U.S. Attorney’s Office, Patrick received the U.S. Attorney’s Excellence in Criminal Litigation Award, as well as commendations from the SEC, FBI and U.S. Treasury.
