A group of state plaintiffs in the Microsoft antitrust case will ask for a five-year extension of a large portion of the 2002 judgment against the company, the group's lawyer said Tuesday.

California, Connecticut, Iowa, Kansas, Minnesota, Massachusetts and the District of Columbia -- known as the "California group" -- want an extension of most of the middleware portions of the judgment, said Stephen Houck, a lawyer for the group. Microsoft still retains a huge lead in the operating system and Web browser markets, he said.

"Microsoft continues to have a stranglehold over the two products . . . that nearly all consumers use," Houck said during an antitrust compliance hearing in U.S. District Court for the District of Columbia. "Very little has happened in five years . . . in those markets."

The California group of states -- the larger of two groups of states that sued Microsoft for antitrust violations -- will ask for an extension of all the middleware portions of the antitrust judgment, except for a section that governs the royalties Microsoft can charge PC manufacturers for the Windows operating system. Most of the antitrust judgment was scheduled to expire in November.

Microsoft lawyer Rick Rule said the company would need time to respond to Houck's proposal. Microsoft first heard of the plan to ask for an extension on Friday, he said, and the California group plans to file a formal extension request with the court in mid-October.

Rule seemed to suggest Microsoft would fight the five-year extension. U.S. District Court Judge Colleen Kollar-Kotelly declined to impose a 10-year judgment in 2002, he said. "We think the picture of the computer industry is much rosier," Rule added. "We think it's clear that the decree has done its job."

Microsoft spokesman Jack Evans said the company will respond in more detail after it has seen the extension request. "We're a bit surprised that a few states are now requesting an extension of the consent decree, since they indicated just last month that they're not too fond of it," Evans said.

In August 2006, Microsoft already agreed to an extension of the section of the judgment requiring it to make its communications protocols available to other software vendors. Microsoft's efforts to fix technical documentation for the protocols have run into several delays. Houck on Tuesday asked Kollar-Kotelly to extend the communications protocol section of the judgment until 2012.
