SCO Group v. DaimlerChrysler was a lawsuit filed in the United States, in the state of Michigan. In December 2003, SCO sent a number of letters to Unix licensees. In these letters, SCO demanded that the licensees certify certain things regarding their usage of Linux. DaimlerChrysler, a former Unix user and current Linux user, did not respond to this letter. On March 3, 2004, SCO filed suit against DaimlerChrysler for violating their Unix license agreement, by failing to respond to the certification request made by SCO. The parties agreed to a stipulated dismissal order on December 21, 2004. The case was dismissed without prejudice, but if SCO wishes to pursue the timeliness claim again, it must pay DaimlerChrysler's legal fees since August 9. On December 29, 2004, SCO filed a claim of appeal notice. On January 31, 2005, the claim of appeal was dismissed.
