In December 2010, the Federal Circuit issued its new ruling on the case. The Federal Circuit essentially re-iterated the arguments it had made the first time. Its decision acknowledged the Supreme Court's Bilski decision, but still found the first two steps were transformative and that the claim as a whole was patentable. The Federal Circuit went into more depth on the third step, the "mental step", noting that:a subsequent mental step does not, by itself, negate the transformative nature of prior steps. Thus, when viewed in the proper context, the final step of providing a warning based on the results of the prior steps does not detract from the patentability of Prometheus's claimed methods as a whole.
