April 20, 2011 — Microsoft will not be able to keep patents it proposed to buy from Novell under an agreement with the U.S. Department of Justice announced Wednesday. Novell, distributor of the SUSE Linux OS, has agreed to change its proposed deal to sell patents to CPTN Holdings, a Microsoft-organized consortium of companies, in order to satisfy DOJ concerns about the impact on open-source software, the DOJ said.
