The software maker faces new cases alleging that it suppresses competition in operating systems and applications.
One of the class actions--brought
in the same Washington federal court where the Justice Department (DOJ)and 19 states are prosecuting Microsoft in a high-profile antitrust suit--also names Compaq Computer, Dell Computer, and Packard Bell NEC for allegedly conspiring with the Redmond, Washington, company to profit from its alleged
monopoly.
Filed Tuesday, the suit was brought on behalf of Gravity, a Fort Worth, Texas, maker of document management software. It accuses Microsoft and the three PC makers of limiting buyers' choice of operating systems and applications and keeping prices for those products artificially high.
In a separate lawsuit filed yesterday in San Francisco Superior Court, a San Jose, California, man who purchased an Intel-based computer last year is accusing Microsoft of blocking superior operating systems from hitting the market and of charging monopoly prices, in violation of California antitrust law. The suit does not name any other party as a defendant.
A Microsoft spokesman denied the allegations.
The two new lawsuits are nearly identical. Both draw liberally from evidence and charges already heard at Microsoft's antitrust trial. Both actions allege a broad series of illegal conduct, including attempts to crush Netscape Communications' Navigator browser and Sun Microsystems' Java programming language.
Representatives from Compaq, Dell, and Packard-Bell were not immediately available for comment.
This week's class actions mean Microsoft is now fighting antitrust charges on at least five different fronts. In addition to the antitrust trial pending in Washington, the software giant is also defending suits filed by Caldera and Bristol Technology. Two other companies, Sun and Blue Mountain Arts accuse Microsoft in court of unfair business practices.
