Introduced on January 31, 2025 by Patrick Ryan
This bill aims to stop “double patenting” on medicines so cheaper generics and biosimilars can reach patients sooner. If a drug company lists more than one patent for the same drug, it must prove in certain court or FDA‑related challenges that each patent covers a truly different invention. If it can’t, protection from the extra patents ends when the first patent runs out, rather than stretching exclusivity longer through overlapping patents .
It also tells the U.S. Patent and Trademark Office to review how it examines drug and biologic patents, make improvements to avoid granting multiple patents on the same product unless they are distinct inventions, and report recommendations to Congress within one year of the law taking effect .
