Biologics is part of our work in Life Sciences.
Introduced nearly ten years ago, the Biologics Price Competition and Innovation Act (BPCIA) opened the door for companies to seek U.S. Food and Drug Administration (FDA) approval to manufacture and sell biosimilar or interchangeable versions of brand name biological products. The BPCIA provides reference product sponsors with 12 years of market exclusivity. It also provides a statutory basis for patent litigation between the reference product sponsor and the biosimilar, as patents can provide additional exclusivity for the branded product. Unlike the Hatch-Waxman Act, the BPCIA does not require reference product sponsors to list patents in an Orange Book equivalent. Instead, it defines specific pre-litigation procedures, sometimes called the “patent dance,” that requires identification of relevant patents and each party’s basis for infringement and validity.
