Doherty, however, disagreed, saying RealNetworks is at an unfair disadvantage to Microsoft.
"We have PCs here, where installing Windows Media 9, not the Windows Media that ships with Windows, derails other multimedia programs, including Real," Doherty said. "Can Microsoft fix that? Yes, they have the resources to fix it. Have they chosen to? No."
As to whether Microsoft is obligated to make the technical changes needed in this example is a question that would need to be settled in court. "That's what Rob (Glaser, chief executive of RealNetworks) wants. He wants that day in court," Doherty said.
RealNetworks argues that despite the innovation of its product line that has helped placed the company on track for its sixth straight quarter of revenue growth, the company's business would be substantially larger if Microsoft played by the rules and did not unfairly leverage its Windows monopoly.
Microsoft conduct that RealNetworks claims is illegal includes failure to disclose interface information for Windows and imposing restrictions on PC makers. Both are the same actions that were found illegal in the federal government's suit against Microsoft. In that suit, a federal court found that Microsoft unfairly used its Windows monopoly during its browser war against Netscape Communications Inc. in the late 1990s.
