Patent Eligibility Restoration Act of 2025

HR 3152, the Patent Eligibility Restoration Act of 2025, clarifies which inventions can receive patent protection under U.S. law. It eliminates judicial exceptions that previously made many inventions ineligible, stating that any useful process, machine, manufacture, or composition of matter is eligible unless it falls into specific excluded categories. These exclusions include mathematical formulas not tied to an invention, mental processes, unmodified human genes (whether in the body or isolated), unmodified natural materials, and purely economic or business methods (though methods requiring a machine, like a computer, remain eligible). The bill directly affects inventors, patent attorneys, and companies seeking patents, particularly in biotechnology, software, and business-related fields. It aims to reduce legal confusion by making patent eligibility rules more consistent and predictable.
