A July E.U. court ruling sanctioning the re-sale of software licenses could damage the European sales of enterprise software vendors such as Microsoft (MSFT), Oracle (ORCL), and SAP, as cost-sensitive companies opt for second-hand "copies" selling at a 30%-70% discount. Germany's UsedSoft, the winning party in the E.U. ruling, says it has seen demand triple since the decision was made. Most U.S. software contracts forbid the re-sale of licenses.
