FTC v. Microsoft Corporation

Plain English (For Everyone)

A federal court decided that the FTC likely won't win its case to stop Microsoft from buying Activision Blizzard, the company behind games like Call of Duty. The court found the FTC's concerns about Microsoft harming competition by making games exclusive were too uncertain. This means the deal can move forward for now.

For Legal Practitioners

The Ninth Circuit affirmed the denial of a preliminary injunction, holding the FTC failed to demonstrate a likelihood of success on the merits or irreparable harm. The court found the FTC's theories regarding anticompetitive effects in the console gaming market, particularly concerning game exclusivity, were too speculative. This decision significantly impacts the FTC's ability to block mergers based on future, unproven harms.

For Law Students

This case illustrates the high bar for obtaining a preliminary injunction in antitrust litigation. The Ninth Circuit applied de novo review to the legal merits, finding the FTC's speculative claims about Microsoft potentially withholding Activision games from rivals insufficient to show a likelihood of success or irreparable harm, thus affirming the denial of the injunction.

Newsroom Summary

A federal appeals court has allowed Microsoft's acquisition of Activision Blizzard to proceed, rejecting the FTC's attempt to block the deal temporarily. The court found the FTC's arguments that Microsoft would harm competition by making popular games exclusive were too speculative.

Standard of Review

De novo review for legal conclusions, abuse of discretion for preliminary injunction decisions. The Ninth Circuit reviewed the district court's denial of a preliminary injunction de novo as to the legal conclusions regarding the likelihood of success on the merits, and for abuse of discretion regarding the overall decision to deny the injunction.

Procedural Posture

The Federal Trade Commission (FTC) sought a preliminary injunction to block Microsoft Corporation's acquisition of Activision Blizzard. The district court denied the injunction, and the FTC appealed to the Ninth Circuit.

Burden of Proof

The FTC, as the moving party seeking a preliminary injunction, bore the burden of demonstrating a likelihood of success on the merits of its antitrust claims and a likelihood of suffering irreparable harm if the injunction was not granted. The standard required a clear showing of probable success.

Judges

• Kimberly J. Mueller

Scenario: A gamer is worried that if Microsoft buys Activision Blizzard, games like Call of Duty will only be available on Xbox.

Your Rights: Consumers have the right to a competitive market that prevents monopolies from unfairly restricting access to popular products. However, courts require concrete evidence of harm, not just speculation, to block a merger.

What To Do: Continue to monitor news and official statements from the FTC and the companies involved. If anticompetitive practices are suspected, consumers can report concerns to the FTC.

Scenario: A small game developer is concerned that a major acquisition by a tech giant will lead to less competition and fewer opportunities for independent studios.

Your Rights: Antitrust laws aim to protect competition, which benefits smaller businesses. However, proving that a specific merger will harm competition requires demonstrating substantial anticompetitive effects, which can be difficult.

What To Do: Document any instances where the acquiring company's practices appear to stifle competition or disadvantage smaller developers. Report these concerns to antitrust enforcement agencies like the FTC or DOJ.

Is it legal for Microsoft to buy Activision Blizzard?

Depends. While the Ninth Circuit allowed the acquisition to proceed by denying a preliminary injunction, the underlying antitrust review by the FTC and potentially other regulatory bodies is ongoing. The legality hinges on whether the acquisition substantially lessens competition, which is a complex legal question still being litigated.

This ruling is specific to the Ninth Circuit's review of the preliminary injunction. Other jurisdictions or ongoing investigations may reach different conclusions.

For Gamers

The ruling means that popular Activision Blizzard games are less likely to become exclusive to Microsoft's platforms in the immediate future, as the FTC's attempt to block the deal on these grounds was unsuccessful at the preliminary injunction stage. However, the long-term availability and platform strategy remain subject to ongoing review and Microsoft's business decisions.

For Competitors (e.g., Sony)

Competitors like Sony may see this as a temporary reprieve, as the FTC failed to block the merger preliminarily. However, the core antitrust concerns about market concentration and potential exclusionary conduct remain relevant in the broader regulatory and legal landscape.

For Microsoft

This ruling is a significant step forward for Microsoft's acquisition of Activision Blizzard, removing a major immediate legal hurdle. It allows the company to proceed with integrating Activision's assets, although the underlying antitrust scrutiny continues.

For The FTC

The FTC suffered a setback in its attempt to block the merger at the preliminary injunction stage. This ruling highlights the difficulty the agency faces in proving speculative future harms in court, potentially requiring stronger evidence in future merger challenges.
