Microsoft Windows Antitrust Class Action Litigation (Ohio and Kentucky Cases)

We served as counsel for Microsoft Corporation in Ohio and Kentucky class action antitrust cases involving the Windows operating system. We obtained dismissal of the Kentucky class action suit against Microsoft (Jefferson Circuit Court, July 21, 2000), which was affirmed by the Kentucky Court of Appeals in the first Windows antitrust case to be decided by a state appellate court, Arnold v. Microsoft Corp. (Kentucky Court of Appeals, November 21, 2001), and the Kentucky Supreme Court declined to hear a further appeal. We obtained dismissal of a similar Ohio state court suit (Hamilton County Court of Common Pleas, August 6, 2002), which was affirmed by the First District Court of Appeals, Johnson v. Microsoft Corp., 155 Ohio App. 3d 626 (2004), and by the Ohio Supreme Court, 106 Ohio St. 3d 278 (2005).
