Stephen Medlock, a senior associate, focuses his practice on antitrust litigation and criminal investigations, with an emphasis on the overlap between antitrust and intellectual property law and high-technology markets. He handles all substantive aspects of antitrust matters, including drafting dispositive motions, planning and executing discovery strategies, taking and defending depositions, working with expert witnesses, preparing witnesses to testify at trial and before grand juries, advocating before the US Department of Justice and Federal Trade Commission, and counseling clients concerning on-going antitrust risks. His depositions and briefs have been quoted in the Washington Post, the New York Times, The Atlantic, and the Baltimore Sun.

Antitrust-IP Litigation and Counseling. Stephen regularly represents clients in antitrust litigation that overlaps with the use and acquisition of intellectual property rights. These cases frequently involve claims that a dominant firm has denied a rival access to a portion of a proprietary system or that a company with a sizeable market share and strong intellectual property rights has engaged in monopolization. Stephen has litigated for both plaintiffs and defendants in these antitrust-IP cases. In addition, Stephen often counsels companies on the antitrust risks associated with licensing or refusing to license patents.

Antitrust Litigation. Stephen’s representations have included some of the largest antitrust and unfair competition cases filed by private plaintiffs and the class action bar. These matters have included a variety of legal theories including price-fixing, monopolization, exclusive dealing, tying, Robinson-Patman Act violations, patent misuse, and business torts. Recently, Stephen helped obtain summary judgment for Nestlé USA in In re Chocolate Confectionery Antitrust Litigation, one of the largest multi-district antitrust class actions to date. In 2015, Global Competition Review nominated In re Chocolate Confectionery Antitrust Litigation as “Litigation of the Year, Cartel Defense: Creative, Strategic, and Innovative Litigation on Behalf of a Defendant.”

Criminal Antitrust Investigations. Stephen regularly defends organizations and individuals facing criminal antitrust investigations. He assists in conducting sensitive internal investigations, counseling clients on potential criminal exposure, advocating for clients before the US Department of Justice, and preparing individuals to testify before grand juries. In addition, Stephen has authored multiple articles concerning how organizations should respond to search warrants executed in antitrust investigations. Many of these criminal matters have been resolved without indictment.

Stephen regularly participates in the American Bar Association’s Section of Antitrust Law where he is a Vice Chair of the Exemptions & Immunities Committee and the co-editor of the forthcoming third edition of the Noerr-Pennington Doctrine treatise.
