Our Services

Katten's Antitrust and Competition attorneys handle the full range of antitrust engagements. We advise clients on issues arising from relations with competitors, pricing, product distribution, monopolization, tying, group boycotts, price discrimination and intellectual property matters. Our antitrust litigation work includes representation of clients in government and private suits (including class actions), competitive tort situations, civil and criminal investigations (such as grand juries), and competition claims arising out of intellectual property matters. Katten's antitrust litigators include former Assistant US Attorneys and Department of Justice attorneys.

We also possess deep experience with mergers and acquisitions and the design and operation of joint ventures and other competitor collaborations. We have obtained antitrust merger clearances for hundreds of transactions, both under the Hart-Scott-Rodino Act and foreign merger control regimes. On transactions that raise substantive competition concerns, Katten’s Antitrust and Competition team gets involved in the matter early to minimize substantive antitrust risk and position the deal for quick antitrust clearance. Where transactions are investigated by the Federal Trade Commission, the Department of Justice, or state attorneys general, we appear before the investigating agency and defend the deal. Where transactions are investigated by foreign competition regulators, we work with local counsel to obtain antitrust clearance.

The Antitrust and Competition practice additionally has extensive experience with foreign antitrust investigations, cross-border transactions and international business operations. We have strong relationships with foreign competition lawyers who can be retained quickly when the need for overseas counsel arises, enabling us to work with foreign counsel seamlessly.

Katten's philosophy is to learn how our clients' businesses work, understand their business objectives and help them navigate through an increasingly complex antitrust and regulatory environment. We work with our clients closely to help them achieve their business objectives.

Plaintiff, Speedo's primary competitor in the sale of competitive racing swimsuits, sued Speedo in the US District Court for the Central District of California for false leading advertising, Lanham Act violations, monopolization, exclusive dealing and other alleged torts. Plaintiff claimed that Speedo misrepresented the test results of swim time improvements achieved using the LZR Racer. Plaintiff also claimed that Speedo's sponsorship of USA Swimming—the national governing body for amateur swimming in the United States—and its head coach gave Speedo an unfair advantage in marketing its suits to elite swimmers and other swimmers who race. After a motion to dismiss, in which some of plaintiff's claims were dismissed, the parties engaged in extensive discovery. After two motions for summary judgment, plaintiff's remaining claims were dismissed. Plaintiff did not appeal.
