In re Microsoft Corp. Antitrust Litigation, 333 F.3d 517 (4th Cir. 2003)

In Brief

The Microsoft Antitrust Litigation stands as one of the most significant legal battles in the realm of technology and intellectual property. Filed by the United States Department of Justice and associated state attorneys general in 1998, it charged Microsoft Corporation with engaging in anti-competitive practices designed to preserve its monopoly in the market for Intel-compatible personal computer operating systems.

Key Issue

Did Microsoft's conduct constitute monopolistic practices in violation of the Sherman Antitrust Act, specifically sections 1 and 2, by unlawfully maintaining its monopoly power and engaging in exclusionary practices?

The Rule

Under the Sherman Antitrust Act, section 1 prohibits concerted actions that restrain trade unreasonably, while section 2 prohibits monopolization, attempts to monopolize, or conspiracies to monopolize any part of interstate commerce.

Bottom Line

The court held that Microsoft had indeed maintained its monopoly through anti-competitive means, violating section 2 of the Sherman Antitrust Act. The court found that Microsoft unlawfully tied its browser to its operating system and utilized exclusionary tactics that harmed competition.

Why It Matters
