The claims are not personally signed and transfer the right to be paid to Lindows.com, which the settlement does not allow, Microsoft said in its court filing.Anyone who has filed a claim through the Lindows.com service should be sent an official claim form by the claims administrator, Microsoft said.The filing in San Francisco Superior Court last week comes after Microsoft in late September sent Lindows.com a notice demanding it take down the MSfreePC site. The site is still up and running.Lindows.com launched MSfreePC.com in September as a way for California software buyers to get a piece of the settlement. The site offers Lindows software and Sun's StarOffice suite in exchange for a claim and the vouchers certain software buyers are entitled to under the settlement.Under the\u00a0settlement agreement, consumers with valid claims can use their proceeds to buy a wide range of hardware or software, including the Lindows operating system, Microsoft spokeswoman Stacy Drake said Monday. "We are concerned, however, that the Lindows Web site misuses the court-approved California settlement as a marketing tool for their products."Lindows.com calls Microsoft's attempt to shutter its site a "transparent attempt" to reduce the amount of money it has to pay out, the company said in a statement Monday. Two-thirds of any unclaimed settlement vouchers will be donated to the neediest California public schools, one-third defaults back to Microsoft.Under the settlement announced in January, those who bought Microsoft's operating system or productivity software for use in California between Feb. 18, 1995, and Dec. 15, 2001, can get vouchers worth between $5 and $29 depending on the product bought.The class-action lawsuit accused Microsoft of overcharging for its software. The company has settled 10 suits like it for a total of approximately $1.55 billion. Last week Microsoft announced preliminary court approval of a settlement in North Carolina.
