Novell is concerned that Microsoft could stop selling SUSE Linux coupons if the GPLv3 remains in its current form.
Its worries were aired in the delayed regulatory filing of its annual report for the fiscal year to October 31, 2006, on Friday.
The 144-page document posted to the Securities and Exchange Commission (SEC) Web site contained "redacted" (confidential information withheld) versions of Novell's business, patent and technology agreements with Microsoft, which it signed in November 2006.
