Amgen, Inc.. v. Hospira, Inc..

The Biologics Price Competition and Innovation Act, 42 U.S.C. 262, establishes a scheme for adjudicating claims of patent infringement in the FDA's approval of “biological products.” To obtain FDA approval, the sponsor of a new biological product must demonstrate that it is “safe, pure, and potent.” For a “biosimilar” product based on an approved “reference” product, a party may submit an abbreviated “subsection (k)” application that “piggybacks” on the showing made for an approved reference product but must provide the reference product's sponsor with its subsection (k) application and information that describes the manufacturing process. The parties then collaborate to identify patents for immediate litigation. The second phase is triggered by the applicant’s notice of commercial marketing and involves any patents that were included on the lists but not previously litigated. Hospira's subsection (k) application sought approval of a biosimilar of EPOGEN®, Amgen’s FDA-approved product, Although Amgen asserted that Hospira failed to disclose the composition of the cell-culture medium used during manufacturing, the parties began identifying patents. Amgen claimed that it could not assess the reasonableness of asserting infringement claims concerning other patents for culturing cells and moved to compel discovery on the composition of Hospira’s cell-culture medium in its suit on listed patents. The court denied Amgen’s motion, stating that the information had no relevance to the asserted patents. Amgen appealed that interlocutory order. The Federal Circuit dismissed, holding that it lacked jurisdiction under the collateral order doctrine and that Amgen failed to satisfy the prerequisites for mandamus. View "Amgen, Inc.. v.
