His commercial litigation experience encompasses business disputes, false advertising, consumer protection and fraud, FCA, and extensive class action defense work; antitrust and unfair competition matters; and intellectual property litigation, such as trademarks, patents, and trade secrets.
Jon served as the Nation’s lead environmental civil and criminal enforcement official and litigator, as Acting Assistant Attorney General for the Environment & Natural Resources Division (“ENRD”) of the U.S. Department of Justice (DOJ). Jon led ENRD’s 425 lawyers, overseeing 6,500 active matters and managing an annual budget of more than $150 million.
