Katrina Robson is a partner in Willkie’s Antitrust & Competition Group. She is based in the Firm's Washington, DC office. 

A globally recognized antitrust litigator, Katrina has tried some of the most significant antitrust disputes in recent years, including historic cases related to clearance for multi-billion dollar mergers. She represents clients in complex, high-profile antitrust and competition litigation against both government agencies and private parties. Her representations include merger, single-firm conduct and restraint of trade cases, agency investigations, and private and government litigation. She also counsels clients on a variety of issues, including monopolization, vertical restraints and integration, merger advocacy and clearance, general antitrust compliance and global litigation strategy.

Katrina defended AT&T and Time Warner’s $100 billion telecommunications-media merger against a challenge by the Department of Justice in the “antitrust trial of the century”, one of only three trial attorneys representing both clients. She obtained a cutting-edge monopolization verdict on behalf of US Airways in its antitrust action against Sabre, a two-sided technology platform company. Katrina also obtained clearance for Schwab’s $26 billion acquisition of TD Ameritrade, US Airways’ $11 billion merger with American Airlines, and General Mills’ acquisition of organics icon Annie’s.

Katrina has been recognized by leading publications including Chambers & Partners (as a “sought-after antitrust litigator” with “great trial experience”), Legal 500 US (for both antitrust and general commercial disputes) and Global Competition Review (on its international list of “Women in Antitrust”). A leader in the legal community, Katrina serves as Vice Chair of the Insurance and Financial Services Committee in the ABA’s Antitrust Section, is a regular contributor to antitrust law publications, and led a pro bono team to win a “monumental” trial decision declaring the educational funding system in Pennsylvania unconstitutional.
