Other key members of the team include Gregg LoCascio and Richard Cunningham, both of whom are based in Washington DC – LoCascio is recognized for his IP work, in which he is regularly involved in trial cases and preliminary injunctions, while Cunningham concentrates on antitrust and consumer protection law, often securing clearance for deals from the FTC and DOJ.
