When Linspire 6.0 is released next month, it will include the fruits of the recently announced marriage between Linspire and Microsoft. Linspire CEO Kevin Carmony says he has been in talks with Microsoft for about a year and a half before reaching an agreement.

The no-lawsuit agreement reached in June between Linspire and Microsoft earlier this year is almost useless to Linspire customers because of tight restrictions on what the deal covers, according to a high-profile open source legal commentator.

LINUX DISTRIBUTOR Linspire has shown what it is costing it to sign a deal with Microsoft over patents.

This morning a press release winged its way from Linspire which said the outfit was "joining the current efforts to improve the ability of OpenOffice.org users to work with the Office Open XML format by increasing the interoperability between ODF and Open XML".

On July 5, Microsoft quietly released a "Covenant to Customers" to clear up how it is handling its patent deal with Linux distributor Linspire. Instead, it did little but puzzle and annoy members of the Linux community.

Microsoft says software that's licensed under GPLv3 isn't covered by the patent protection deal it recently signed with desktop Linux distributor Linspire.

Microsoft's partnership with Novell got a lot of people in the open-source community fired up. Since then, Microsoft's Linux deals with Linspire and Xandros have just thrown gasoline on the fire. Now, it appears that Red Hat, the leading Linux company and the most vocal opponent to Microsoft wheeling and dealing, tried to make its own deal with Microsoft before the Novell one was released.

Over two years ago, Microsoft and Novell signed an interoperability deal. Part of this agreement was a patent deal that suggested that Linux infringed on Microsoft's IP. Since then, Microsoft has signed a number more of these deals with various companies, but the Novell one is still the most famous.

Linspire is entangled by difficulties after engaging in Microsoft's patent farce

Red Hat, the largest Linux vendor, and Ubuntu-maker Canonical have both rejected calls from Microsoft to forge a deal similar to the one the Redmond giant signed with Linux distributors Novell, Xandros, and Linspire.
