Now that the Supreme Court has vacated and remanded both the Classen and Prometheus decisions, the Federal Circuit must revisit these issues. For Prometheus, the decision may be simpler, because the claims were already held to meet the machine-or-transformation test. Although the Supreme Court’s Bilski decision held that the M-or-T test was not the only test by which patent-eligibility can be determined, the Supreme Court seemed to have agreement from all nine Justices that the machine-or-transformation test was still a useful tool and valid option. See, e.g., Bilski, slip. op. at 2 of J. Breyer’s concurrence. Although a claim that does not meet the M-or-T test may still be patent-eligible under other theories, one can presume that the M-or-T test is still a “safe harbor” for claims that meet its provisions. The Federal Circuit’s re-visitation of Prometheus will be the first opportunity for this presumption to be tested.
