While Mayo and Alice presented a two-part “framework” to address when a particular claimed invention preempts a “fundamental principle,” neither case purported to have that framework replace a preemption inquiry nor authorize a court to ignore the ultimate question, i.e., does the claim preempt a fundamental principle instead of merely claim a practical application of such a principle? The failure to consider preemption has resulted in courts and the PTO over-using §101 in a gatekeeper or threshold fashion for which it was never intended to be used, either as enacted by Congress or as interpreted by the Supreme Court.
