Leon Stambler v. Mastercard International Inc.

Whether covered business method review, an adversarial process used by the Patent and Trademark Office to analyze the validity of existing patents, violates the Constitution by extinguishing private property rights through a non-Article III forum without a jury.

Whether the Federal Circuit’s issuance of Rule 36 judgments without opinions for the disposition of appeals from the Patent and Trademark Office violates 35 U.S.C. § 144’s requirement that the Federal Circuit “shall issue” its “mandate and opinion” for such appeals. The first question is substantially similar to that presented in Oil States Energy Servs., LLC v. Greene’s Energy Grp., LLC, No. 16-712, 2017 U.S. LEXIS 3727, at *1 (June 12, 2017), which has been argued and is awaiting decision by the Court. The second question is identical to that presented by the Petition for writ of certiorari in Celgard, LLC v. Matal (No. 16-1526) (question #2, petition pending).
