Bill MacLeod chairs the firm’s Antitrust and Competition practice group. A former bureau director at the U.S. Federal Trade Commission (FTC), Mr. MacLeod offers his clients decades of experience in competition law, trade regulation, advertising, privacy and security issues, from both an agency and business perspective. Mr. MacLeod represents some of the most prominent organizations driving business and industry today. He resolves serious, complicated problems with stakes reaching into the billions of dollars for multi-national corporations, domestic and international privately-owned companies and rapid-growth ventures.

Mr. MacLeod guides major U.S. and global corporations through investigations, approvals and the sophisticated challenges associated with mergers and acquisitions. He has obtained FTC and Antitrust Division clearance of numerous acquisitions and joint ventures in a range of industries, including medical devices, grocery products, defense contracting and steel manufacturing. Mr. MacLeod also has assisted clients with protecting their interests threatened by consolidation in industries that range from accounting to travel services.

Mr. MacLeod has been involved in the resolution of major initiatives with notable and high-profile results. He served as special counsel for a government investigation of one of the world’s largest and most complex manufacturing industry mergers. He obtained one of the largest judgments ever awarded in an advertising and antitrust case, and successfully defended a major marketer in the FTC’s first trial under the modern unfairness doctrine. Mr. MacLeod was involved in settling the FTC’s first preliminary injunction action in an ad-substantiation case. He has also handled large-scale investigations of privacy and data security practices, litigated a multi-district Sherman Act case over online pricing, and resolved a myriad of price discrimination claims.

In addition, Mr. MacLeod counsels and defends companies and trade associations on pricing, advertising, distribution, intellectual property licensing and competitor relations. In his work with trade associations and their members, he has resolutely fought onerous regulations and advocated sensible, viable policies on competition, biotechnology, health and privacy. In his work on privacy and security, Mr. MacLeod defended the practices of major household-name retailers, manufacturers and financial services companies. He also represents companies in advertising, antitrust and intellectual property disputes before the state and federal courts, the FTC and the National Advertising Division of the Council of Better Business Bureaus.  

Mr. MacLeod currently serves as chair of the American Bar Association’s Antitrust Section. Over the last years, he was named the Washington, D.C. Advertising “Lawyer of the Year” by Best Lawyers®, and has been included in The Best Lawyers in America©, the The Legal 500 U.S., and among Washington, D.C.’s Super Lawyers. Mr. MacLeod’s clients appreciate his demonstrated skill in translating legal esoterica into functional and useful business advice. He is highly valued for his perseverance and ability to produce tangible results and first-rate work product. Mr. MacLeod consistently delivers the requisite experience and intellect needed to assist his clients in achieving their goals. Clients and colleagues alike appreciate his encyclopedic knowledge of antitrust and consumer protection law.

Mr. MacLeod previously served as director of the FTC’s Bureau of Consumer Protection, which is the chief federal prosecutor of unfair and deceptive advertising. In this position, he served as the U.S. delegate to a committee of the Organization for Economic Cooperation and Development, where agency heads of Europe, Australia and Japan develop policies for financial regulations, product safety and international advertising. Mr. MacLeod also held such positions as advisor to the assistant attorney general of the U.S. Department of Justice’s Antitrust Division; director of the FTC’s Chicago regional office; and attorney advisor to the FTC chairman.
