SP Technologies has sued Apple for infringement on a patent that SP filed in August 2000. SP Technologies, a Florida company, is seeking a permanent injunction against the Mac-maker. SP also seeks damages and attorney fees. SP’s patent, which was awarded in August 2004, is for a “method and medium for computer readable keyboard display incapable of user termination.” The document describes software that allows users to input directions on a virtual keyboard that cannot be minimized or closed.
