Greg's practice focuses on complex commercial litigation and arbitration and the Foreign Corrupt Practices Act (FCPA). His diverse experience includes significant commercial litigation involving contractual, business tort, and product liability claims; False Claims Act (FCA) matters; Administrative Procedure Act (APA) issues; intellectual property disputes; international arbitrations; and anti-corruption matters.
Among other high-profile matters, Greg represents a defense contractor in an international dispute with the Republic of Korea stemming from a terminated Foreign Military Sales transaction, in which he obtained a declaration, affirmed by the Fourth Circuit, that Korea’s claims against the contractor were improper under federal common law; represents the same contractor in a multi-million-dollar breach of contract, indemnity, and business tort dispute with its subcontractor, in which the court dismissed all but two of the subcontractor’s multiple claims; represents FastShip, the inventor of a revolutionary hull design, in a misappropriation of trade secrets and breach of contract case against Lockheed Martin Corporation; represented a patent holder in a successfully settled, multi-party infringement litigation concerning wireless e-mail products and systems; represented a New York Stock Exchange (NYSE)-listed French multinational in a $4 billion securities class action suit (settled for less than $7 million, or less than 1 percent of the original claims); represented several oil companies in a breach of contract claim against the United States resulting in a $1.8 billion award; represented a South American pharmaceutical company in an International Chamber of Commerce (ICC) arbitration involving contractual and patent claims, successfully negating a non-compete provision in an agreement concluded by two sophisticated companies; and represented a European satellite operating company in an ICC arbitration involving multiple contractual and business tort claims and counterclaims, resulting in a large, favorable award for his client.
Greg's FCPA experience runs the gamut, including managing world-wide internal investigations; conducting due diligence on international agents, joint venture partners, and other third parties; and designing corporate anti-corruption compliance and training programs.
