I see that Microsoft has patented the "sudo" command:

Microsoft has been granted a patent for the sudo command, because apparently you can patent a command that goes back to the mainframe days as long as you explain that it's a "personalized version" with a GUI.

You could say that the patent office was asleep for this one, but seriously - they seem to be asleep for all of them. Software patents just need to die. Copyright should be enough - let innovation happen without the value subtraction of the trollls - or, in this case by MS, the defensive patent to be used against trolls...
