no longer facing action from the Federal Communications Commission, the company had become emboldened to "dominate the data compression market". In 1994, a California jury ruled the infringement by Microsoft was not willful, but awarded Stac $120 million in compensatory damages, coming to about $5.50 per copy of MS-DOS 6.0 that had been sold. The jury also agreed with a Microsoft counterclaim that Stac had misappropriated the Microsoft trade secret of a pre-loading feature that was included in Stacker 3.1, and simultaneously awarded Microsoft $13.6 million on the counterclaim. While Microsoft prepared an appeal, Stac obtained a preliminary injunction from the court stopping the sales of all MS-DOS products that included DoubleSpace; by this time Microsoft had already started shipping an "upgrade" of MS-DOS to its OEM customers that removed DoubleSpace. By the end of 1994, Microsoft and Stac settled all pending litigation by agreeing that Microsoft would make a $39.9 million investment in Stac Electronics, and additionally pay Stac about $43 million in royalties on their patents.
