Antitrust and Trade Regulation

Robins Kaplan’s Antitrust and Trade Regulation Group is one of the nation’s premier antitrust practices. We are one of the few national practices to have obtained landmark successes on behalf of both plaintiffs and defendants in major antitrust litigation and at trial, including in several of the most significant antitrust cases ever litigated. 

With nearly $10 billion in recoveries for antitrust plaintiffs in the past several years alone and a long history of successfully defending Fortune 100 companies in antitrust disputes, Robins Kaplan regularly ranks as one of the top firms in the United States for antitrust litigation. In acknowledgement of the firm’s successes, Chambers noted that the group is “forward-thinking, creative, and very effective,” and conducts “brilliant plaintiff and defense work.” According to Law360, the firm has a “tried and true formula of grit and economy while taking on some of the largest firms and the biggest companies in the world.”

Our broad range of experience is reflected in the diverse backgrounds of our legal professionals: Our antitrust team includes former trial attorneys from the Antitrust Division of the U.S. Department of Justice, the former co-chair of the antitrust practice of a nationally recognized AmLaw 100 firm, two former U.S. Attorneys, and the current vice-president of the International Academy of Trial Lawyers.


On the plaintiffs’ side, we represent businesses and individuals in classes and direct actions in courts throughout the country, where we have achieved historic recoveries in some of the largest antitrust cases in U.S. history. Some of these include:

  • In re Air Cargo Shipping Services Antitrust LitigationAs court-appointed co-lead counsel, we obtained over $1.2 billion in settlements for air cargo shipping customers who paid allegedly price-fixed surcharge fees.

  • In re Automotive Parts Antitrust Litigation: We have recovered over $1.2 billion to date on behalf of automobile purchasers and lessees in what is presently the second largest indirect purchaser recovery in U.S. history.

  • In re Payment Card Interchange Fee and Merchant Discount Litigation: Our attorneys pioneered this groundbreaking class action, which challenges an alleged conspiracy among credit card companies to price-fix credit card interchange fees. The firm reached a $6.25 billion settlement for the class, which received final approval from the court in December 2019. The settlement, which is subject to possible reduction in the event opt-outs exceed a certain threshold, is believed to be the largest-ever antitrust class action settlement.

On the other side of the "v," Robins Kaplan has a proven track record of successfully defending clients in high stakes antitrust cases and government investigations. Among other notable defenses, we successfully represented UnitedHealth Group and PacifiCare in an antitrust lawsuit alleging price-fixing and fraud related to prescription drug reimbursement, with claimed damages in excess of $1 billion.

Our attorneys also provide antitrust risk assessments for mergers, acquisitions, and joint ventures, as well as antitrust counseling related to sales and marketing practices, distribution agreements, licensing decisions, and compliance training. Disciplined and creative, we know the substantive law and critical strategies required for success in class action litigation in the United States and abroad.
