European Union Microsoft antitrust case

''Microsoft Corp. v. Commission'' (2007
T-201/04
is a case brought by the European Commission of the European Union (EU) against Microsoft for abuse of its dominant position in the market (according to competition law). It started as a complaint from Sun Microsystems over Microsoft's licensing practices in 1993, and eventually resulted in the EU ordering Microsoft to divulge certain information about its server products and release a version of Microsoft Windows without Windows Media Player. The European Commission especially focused on the interoperability issue.

Facts

In 1993, the American software company Novell claimed that Microsoft was blocking its competitors out of the market through anti-competitive practices. The complaint centered on the license practices at the time which required royalties from each computer sold by a supplier of Microsoft's operating system, whether or not the unit actually contained the Windows operating system. Microsoft reached a settlement in 1994, ending some of its license practices, specifically "charging royalties on a 'per processor' basis", which allowed Microsoft to be paid without providing a product and caused systems bundling other software (such as Novell's DOS 7.0) to be more expensive due to the alternative system software incurring an extra cost on top of the Microsoft licensing fee. Additionally, Microsoft agreed to stop requiring that software developers sign non-disclosure agreements preventing them from developing applications simultaneously for Microsoft and non-Microsoft platforms.

In 1998, Sun Microsystems raised a complaint about the lack of disclosure of some of the interfaces to Windows NT. The case widened when the EU examined how streaming media technologies were integrated with Windows.

Judgment

Citing ongoing abuse by Microsoft, the EU reached a preliminary decision in the case in 2003 and ordered the company to offer both a version of Windows without Windows Media Player and the information necessary for competing networking software to interact fully with Windows desktops and servers. In March 2004, the EU ordered Microsoft to pay €497 million ( $794 million or £381 million), the largest fine ever handed out by the EU at the time, in addition to the previous penalties, which included 120 days to divulge the server information and 90 days to produce a version of Windows without Windows Media Player.

The next month Microsoft released a paper containing scathing commentary on the ruling including: "The commission is seeking to make new law that will have an adverse impact on intellectual property rights and the ability of dominant firms to innovate." Microsoft paid the fine in full in July 2004.

In 2004, Neelie Kroes was appointed the European Commissioner for Competition; one of her first tasks was to oversee the fining brought onto Microsoft. Kroes has stated she believes open standards and open source are preferable to anything proprietary
