The thing is, patents are supposed to be non-obvious to a reasonably skilled practitioner of the arts. People have been adding guis to things for years. Does that mean that adding a gui to sudo makes it patentable?
Note: I haven't read the patent. But if it's just adding a gui, IMO it should not be patentable; furthermore our sudo does have a gui, at least, in Linux I never use command-line sudo but rather the KDE graphical tool that elevates my privileges when I run a control panel applet or something similar.
