This week, the full House is poised to take its first action on drug pricing, voting on a pair of bills that would improve access to drug patents. The first bill is H.R. 1520, the Purple Book Continuity Act of 2019, which would codify the publication of patents of approved biological products in the Purple Book, which is a list of approved or licensed biological products. The second bill is H.R. 1503, the Orange Book Transparency Act of 2019, would ensure that relevant patent information in the Orange Book is updated timely and accurately. The Orange Book is a list of approved drug products and therapeutic equivalents. The House is also expected to vote on the Protecting Americans with Preexisting Conditions Act.
