On May 18, 1998, following an extensive investigation, Attorneys General from 20 states and the District of Columbia filed this civil action against the Microsoft Corporation alleging the company had abused its monopoly position in the desktop computer operating system market to destroy and prevent competition. The states and the Department of Justice asserted that Microsoft had used a variety of unlawful tactics in order to maintain its monopoly.
Liability Phase
On October 19, 1998, trial commenced in the District Court. Based upon the evidence presented, the trial court issued extensive findings of fact and conclusions of law, holding that Microsoft had engaged in a broad pattern of anticompetitive conduct to eradicate developing threats to its monopoly. Among other things, the court determined that such conduct violated Section 2 of the Sherman Act and various state law counterparts.
