Patent Eligibility Restoration Act of 2023

This bill clarifies patent eligibility by removing judicial exceptions that previously blocked many inventions from patent protection. It states that any useful process, machine, manufacture, or composition of matter (or improvement) is eligible for a patent, except for unmodified human genes, natural materials, mathematical formulas used alone, mental processes, or business methods not requiring a machine. Patent applicants will no longer face uncertainty about whether their invention qualifies under patent law's eligibility rules. The law aims to provide clear, consistent standards for determining patent eligibility across all courts.
