The Supreme Court on Nov. 26 refused, without comment, to consider an appeal by a software company that alleged MTV Networks Co. and its parent, Viacom Inc., infringed on its trademark.

M2 Software Inc., which develops royalty-tracking and other software for the music industry, sued Viacom and MTV Networks in 1998 for allegedly infringing on its “M2″ trademark by calling its second music television channel “M2: Music Television.”
