The Patent Eligibility Restoration Act of 2025 (PERA 2025), co-sponsored by Senators Blackburn, Hirono, Tillis, and Coons, is intended to amend U.S. patent eligibility law by removing judicial exceptions. Introduced in both houses of Congress, PERA 2025 clarifies that unmodified human genes are not patentable, while also redefining what constitutes a modification. This revision omits the term 'isolated,' allowing for human genes to be considered modified if purified, enriched, or altered through human activity. The bill represents ongoing efforts to reshape patent litigation and innovation in the U.S.
PERA 2025 maintains that unmodified human genes in the human body are not patent eligible, but changes the previous definition of gene modification.
The bill aims to eliminate all judicial exceptions to the U.S. patent eligibility law, with language updates concerning human gene modification.
