The main purpose of the Patent Eligibility Restoration Act of 2025 is to clarify and modify the rules surrounding what inventions can be patented under U.S. law. The current legal framework has led to confusion and inconsistency in patent eligibility, making it difficult for inventors and patent practitioners to understand what can be patented. This legislation aims to restore broader patent eligibility by eliminating certain judicial exceptions that have limited the scope of patentable inventions.
