What is the appropriate standard for determining patent-eligibility under 35 USC 101?

QUESTIONS PRESENTED The questions presented are the same as those presented in the petition for a writ of certiorari filed in connection with American Axle & Manufacturing, Inc. v. Neapco Holdings, LLC, No. 20-891: 1. What is the appropriate standard for determining whether a patent claim is “directed to” a patent-ineligible concept under step 1 of the Court’s two-step framework for determining whether an invention is eligible for patenting under 35 U.S.C. § 101? 2. Is patent eligibility (at each step of the Court’s two-step framework) a question of law for the court based on the scope of the claims or a question of fact for the jury based on the state of art at the time of the patent?
