Plenty At Stake In EU’s Microsoft Ruling Monday

When Europe’s second-highest court rules Monday on Microsoft Corp.’s appeal of its landmark antitrust conviction, more will be at stake for regulators than just the behavior of the world’s largest software company.

Experts say an affirmation of the European Commission’s 2004 order and record 497 million euro ($613 million) fine could embolden regulators as they pursue probes of Intel Corp., Rambus Inc. and Qualcomm Inc., among others.

But a major victory for Microsoft could turn the regulatory landscape upside down, curbing the ambitions of European officials who have recently taken a more aggressive stance against alleged monopolists than regulators in the United States.

The 13 judges on the Luxembourg-based Court have been considering Microsoft’s appeal for 15 months. Judge Bo Vesterdorf — on his last day on the job — will read the order that could change how the world’s most powerful corporations are regulated by Europe.

The case started in the 1990s with complaints from Microsoft rivals about how the software giant used its presence on most desktop computers to elbow into new markets and block competitors. It’s also always been about something more — nothing less than the role of Europeans in the regulation of U.S. companies.

If the Commission’s tougher approach is upheld, that means U.S. companies with a global presence will have to conform to Europe’s rules, said Keith Hylton, a professor at Boston University School of Law.

”The end result is, the EU ends up being the global regulator of dominant firms,” he said.
