SAN FRANCISCO — Microsoft­ Corp. won dismissal of Novell Inc.’s antitrust lawsuit over the WordPerfect computer program.

US District Judge J. Frederick Motz granted Microsoft’s request to close the case in an order issued Monday. A mistrial was declared in December after jurors in Salt Lake City said they were unable to reach a unanimous verdict.

Novell “did not present evidence sufficient for a jury to find that Microsoft committed any acts that violated” federal antitrust laws “in maintaining its monopoly in the operating systems market,” Motz wrote in his ruling.

Novell sought as much as $1.3 billion in damages over allegations that Microsoft, while developing the Windows 95 operating system in 1994, blocked an element of the software to thwart Novell’s WordPerfect and Quattro Pro programs.

Novell “still believes in the strength of its claim and we do intend to pursue an appeal,” Jim Lundberg, vice president of the company’s legal department, said in a statement.
