That would be a compelling story, except that the CAFC and Supreme Court came to the same conclusion on this case, both on the judgement (that the patent was invalid), and largely on the rationale (the plurality of 5 out of 10 judges in the en banc rehearing found that all the claims were patent-ineligible as the Supreme Court found, and a majority of 7 found that at least some of the claims were patent-ineligible.)
