Williams & Connolly LLP handles all aspects of antitrust investigations and litigation, from grand jury proceedings to civil shareholder litigation, and represents major corporations and individuals -- both as plaintiffs and defendants. The firm represented a large Midwestern agriculture corporation in global price-fixing litigation involving all aspects of criminal and civil antitrust representation: criminal grand jury proceedings and subsequent indictments, nationwide federal and state shareholder derivative litigation with associated class action certification proceedings, and other extensive, related civil litigation. The firm frequently represents both individuals and corporations in criminal antitrust investigations, including allegations of price fixing and bid rigging. The firm assisted a client in successfully avoiding indictment in the polyester staple price-fixing investigation. By their very nature, much of the firm's representations in criminal price-fixing and bid rigging cases and/or grand jury investigations never become public. Williams & Connolly LLP's experienced antitrust lawyers have represented senior executives and corporations in criminal grand jury investigations in the industries of defense contracting, plastics, investment banking, graphite electrodes, microprocessing chips and auction houses, among others.

Williams & Connolly lawyers also regularly represent clients in all aspects of civil antitrust litigation. The firm's civil clients include plaintiffs (including Bayer and formerly American Home Products) alleging antitrust violations in the vitamin industry, and major motion picture studios in federal and state civil antitrust investigations and private-party civil litigation. Williams & Connolly LLP represented state attorneys general at trial in their effort to seek more effective remedies in the landmark Microsoft monopoly litigation. The firm is currently defending a pharmaceutical company in civil antitrust class action lawsuits. The breadth of the firm's overall litigation practice and the fact that Williams & Connolly lawyers are multi-disciplinary litigators give the firm valuable capabilities in cases that overlap antitrust and other areas of the law, such as intellectual property, healthcare, biotechnology and sports law.
