As it said it would, Novell (NOVL) filed a federal lawsuit in Utah alleging that Microsoft (MSFT) - Get Report tried to eliminate competition in the office productivity applications market when Novell owned the WordPerfect word processing and Quattro Pro spreadsheet applications.

The lawsuit comes just days after Novell collected a $536 million payment from the software giant in another antitrust dispute.

Novell said its latest suit will draw on the U.S. antitrust settlement with Microsoft, in which the company was found to have monopolized operating systems by driving out competition in related markets.

Novell acquired the WordPerfect word processing program when Novell and WordPerfect merged in June 1994. In a related transaction during the same time period, Novell purchased Quattro Pro, a spreadsheet product, from Borland International. The combined value of WordPerfect and Quattro Pro at the time of the transactions was over $1 billion. Both WordPerfect and Quattro Pro were sold to Corel Corporation in March 1996.

On Monday, Microsoft

agreed to pay $536 million to settle a dispute over Novell's NetWare operating system, which competes with Windows on server computers. In exchange, Novell agreed to pull out of a European Union lawsuit against Microsoft. However, the two companies were unable to resolve their dispute over WordPerfect and Quattro Pro.

Microsoft said Monday that it believed Novell's suit has no merit and has passed the statute of limitations.
