United States v. Microsoft Corp. — Study Notes

253 F.3d 34 (D.C. Cir. 2001)

Study notes for United States v. Microsoft Corp.: professor notes, cold call prep, exam angles, and memory aids.

Microsoft's actions constituted illegal maintenance of monopoly power under Section 2 of the Sherman Act, but the tying claim under Section 1 was overturned due to improper analysis.
Professor Notes

In this landmark antitrust case, the D.C. Circuit addressed the competitive practices of Microsoft during its peak industry dominance in the mid-1990s. The court emphasized the importance of maintaining a competitive market, noting that monopoly power itself is not inherently illegal, but the conduct used to maintain that power can be actionable under Section 2 of the Sherman Act. This case illustrates how the law balances innovation and competition, prompting discussions about whether certain aggressive business strategies stifle competition or foster technological advancement.

Additionally, the court's distinction between the monopolization charge and the tying claim showcases the complexities of antitrust litigation. While the court found that Microsoft illegally maintained its monopoly power, it overturned the tying claim due to inadequate legal reasoning at the district level. This supports the lesson that judicial scrutiny must be rigorous, particularly concerning claims of anticompetitive practices involving product bundles.
