But the things that worry me most of the Fed Cir opinion was how easily and casually they wiped away both Supreme Court and Fed Cir precedent to reach the rule applied to the claims. Without having followed up on all the briefs (did you see how many there were?!?!) and much other than the grant of cert, I still expect prior alternative tests for Section 101 (particularly useful results) to be reinstated.
Jim, I'm not sure I follow you here (though I never read the full CAFC decision, just summaries). Can you elaborate?
I'll have a lot more to say about the oral arguments in a day or two when I'm less busy with work.
