A claim should fail 101 if it claims something that isn't one of the above. The were not claiming to invent a machine (the computer) They were not claiming to invent the process (hedging) They were not claiming to invent a specific improvement to a computer. (software added to the computer) Instead their claim was using a machine to solve a problem. That doesn't fall under 101 unless it falls under a patentable process. SCOTUS said that the 2 step process of (take exising process) and (apply it on a computer) is just a drafting trick to get a patent on old things. If you remove the drafting trick then you have a process with no steps. So they rejected it under 101.
