Katrina Robson

O'Melveny & Myers LLP

Katrina M. Robson represents clients in complex, high-profile antitrust and competition litigation against both government agencies and private parties. Her work has made material differences in the business of some of the country’s most recognized companies.

Katrina held a pivotal role in the high-profile US Airways-American Airlines antitrust litigation that temporarily held up the groundbreaking US$17 billion merger and obtained early antitrust clearance for General Mills’ acquisition of organics icon Annie’s.

Katrina has extensive experience briefing and litigating disputes, having worked on appellate briefs, argued before the Ninth Circuit, and participated in multiple trials and evidentiary hearings.

She has achieved precedential decisions in antitrust litigation, including obtaining summary judgment on a motion for reconsideration for gaming technology company IGT, subsequently affirmed by the Federal Circuit, and dismissal of plaintiffs’ price-fixing claims against Marriott in MDL proceedings.

Katrina also counsels companies on complex antitrust issues.  Katrina has advised Fortune 500 companies on FRAND-related questions, antitrust guidelines and audits, consumer protection questions, and privacy policies and compliance.

Katrina dedicates extensive time to leadership in the legal community.  She is Vice-Chair of the Franchise and Distribution Committee in the ABA Antitrust Section, editor of the forthcoming Consumer Protection Legal Developments Treatise, and a driving member of O’Melveny’s Women’s Leadership Academy, a forum for discussing the leadership challenges confronting women in today’s business environment.
