Caldera vs. Microsoft: Case No. 2:96-cv-645 B. This case mirrored the much larger anti-trust case against Microsoft in Washington D.C. Utah based Caldera, Inc. brought the anti-trust suit against Microsoft for the anti-competitive practice of encoding Microsoft Windows 95 to only run properly if MS-DOS, a Microsoft product, was being used. Caldera's claim was that this practice unfairly inhibited the competition by eliminating DR-DOS as an alternative. Judge Benson denied 4 Motions for Summary Judgment by Microsoft to have the case dismissed. The case was eventually settled by the parties.
