About

Provided by McDermott Will & Emery LLP

McDermott's Chicago-based antitrust practice is a preferred choice for any major class action, cartel defense or private antitrust litigation.

We are one of the premier firms for price fixing/civil class action antitrust defense, and have worked on many cutting-edge cases. We take complex, high-stakes cases to trial, with a track record that is second to none. We’ve counseled numerous corporate and individual clients in various grand jury investigations of alleged price-fixing. We excel at narrowing classes or defeating class certification motions. A particular strength of McDermott’s antitrust team is private plaintiff disputes – cases that put a premium on proven trial skills.

Healthcare a real point of distinction from other Chicago-based antitrust practices. McDermott has been recognized for many years as the premier healthcare firm. When market-leading healthcare and antitrust teams are put together, the result is a winning combination for clients, whether defending against litigation or clearing transactions before the FTC.

A strong feature of our merger control practice is its “stand alone” quality: corporate clients often come to us directly for antitrust support, even though other law firms may be handling the M&A piece. We typically file around 50 Hart-Scott-Rodino notification requirements, annually – this refers to the requirement to file a notification with the FTC and the DoJ in advance of a company merger.
