Court: U.S. Court of Appeals for the Federal Circuit

Docket: 24-1177 

Opinion Date: August 11, 2025

The dispute centers on a patent for a system that automates the adjustment of selectorized dumbbells using an electric motor. The patent describes a dumbbell with stacks of weight plates on each side, a handle, and a movable selector that, when positioned, couples different numbers of plates to the handle. The innovation lies in using an electric motor, operatively connected to the selector, to move it into the desired position based on user input, thereby automating the weight selection process and addressing safety and convenience issues present in prior manual systems.

The United States District Court for the District of Utah reviewed the case after the defendant moved to dismiss the complaint, arguing that the asserted patent claims were ineligible under 35 U.S.C. § 101. The district court applied the Supreme Court’s two-step framework for patent eligibility and determined that all but one claim (claim 19) were directed to an abstract idea and implemented using generic components, thus failing the eligibility test. The court granted the motion to dismiss as to claims 1–18 and 20, but denied it for claim 19, finding that the parties had not sufficiently addressed its eligibility.

On appeal, the United States Court of Appeals for the Federal Circuit reviewed the district court’s decision de novo. The Federal Circuit held that the relevant claims were not directed to an abstract idea but instead to a specific mechanical improvement in selectorized dumbbells. The court found that the claims recited a sufficiently specific structure and method, including the use of an electric motor to automate weight selection, and thus did not preempt all forms of automated weight adjustment. The Federal Circuit reversed the district court’s dismissal of claims 1–18 and 20 and remanded the case for further proceedings.
