European Commission Publishes IT Milestones: Browser Choice Commitment and Interoperability Undertaking in the Microsoft Case

December 16, 2009

On December 16, 2009, the European Commission announced concessions by Microsoft Corporation in two investigations relating to abuses of Microsoft’s dominant position in PC operating systems that excluded competing products in web browsers, server software, and productivity applications. More specifically, the Commission has today published the final text of:

  • a Commitment Decision requiring Microsoft to provide all Windows users with real choice in web browsers
  • a Public Undertaking requiring Microsoft to make interoperability information available for a range of server products (including email and collaboration servers), for Office, and for .Net, as well as to comply with certain obligations with respect to Open Standards.

Cleary Gottlieb has been successfully advising and representing IT companies and trade associations in both aspects of this case. Previous milestones, in which Cleary Gottlieb was also involved, were the 2004 Commission Decision requiring disclosures of work-group server interoperability information and unbundling Windows Media Player, and the 2007 judgment of the European Court of First Instance upholding those decisions and establishing the precedent.
