Microsoft has filed another batch of technical information with the European Commission, in an effort to avoid an increase in fines resulting from a 2004 antitrust ruling against the company, a commission spokeswoman said Monday.On July 12, the commission fined Microsoft 280.5 million euros\u00a0(US$358 million) for not supplying the technical information about the communications protocols used by its workgroup server software requested in the antitrust ruling. The commission calculated the fine at 1.5 million euros\u00a0per day for the period from Dec. 16, 2005, to June 20, and warned the company that the daily fine could increase if it did not supply all the requested documentation by July 31.Since that warning, the company has supplied further documentation on the protocols, and the commission is analyzing it to determine whether it is complete, said the spokeswoman. "I don\u2019t know when the analysis will be finished," she said."From today, they could face a larger fine of up to 3 million [euros]\u00a0a day" if the commission finds the documentation lacking, said the spokeswoman.In its March 2004 antitrust ruling, the commission ruled that Microsoft had abused its monopoly in desktop PC operating systems to gain advantage in the markets for workgroup server operating systems and media player software. It ordered Microsoft to pay a 497 million euro\u00a0fine, to offer a version of its desktop operating system Windows XP without a built-in media player, and to document the communications protocols used by Windows workgroup server products so that others could build competing products.Numerous deadlines for the supply of the documentation have come and gone. The commission initially gave Microsoft 120 days to provide the information, and threatened further fines in March and June last year. On Nov. 10, the commission told Microsoft that it would face fines of up to 2 million euros\u00a0a day if it did not comply by Dec. 15, and finally imposed the 280.5 million fine on July 12.
