An Early Holiday Present for Generics? Legislation Requiring Greater Disclosure by Brands Passes the Senate

Earlier this month, two bills intended to promote generic competitiveness by presenting a clearer idea of the patent landscape covering reference products passed the full Senate, albeit with amendments. These laws, if enacted, will require brand pharmaceutical companies to submit more information about their innovator products. Potential Changes to Orange Book Listing Requirements for Non-Biologics Drugs As part of its current obligations, an innovator product manufacturer must submit to the FDA the patent number and expiration date of any patents that claim the drug or a method of using the drug.

Venue in Hatch-Waxman Cases Limited to District Where ANDA Is Submitted

The US Court of Appeals for the Federal Circuit found that in cases brought under the Hatch-Waxman Act, for purposes of determining venue, infringement occurs only in districts where actions related to the submission of an abbreviated new drug application (ANDA) occur, and not in all locations where future distribution of the generic products specified in the ANDA is contemplated.

Inherent Claim Limitation Necessarily Present in the Prior Art Invalidates Patent

Addressing the issue of obviousness, the US Court of Appeals for the Federal Circuit affirmed the district court’s finding that a patent was invalid based on inherency because the claim limitation was necessarily present in the prior art. Hospira, Inc. v. Fresenius Kabi USA, LLC, Case Nos. 19-1329, -1367 (Fed. Cir. Jan. 9, 2020) (Lourie, J). The patent at-issue is directed to premixed pharmaceutical compositions of dexmedetomidine that do not require reconstitution or dilution prior to administration and remains stable and active after prolonged storage. Hospira makes and sells dexmedetomidine products, including a ready-to-use product called Precedex Premix covered by the patent at-issue. Fresenius filed an Abbreviated New Drug Application (ANDA) seeking approval by the Food and Drug Administration (FDA) to market a generic ready-to-use dexmedetomidine product. Hospira brought suit alleging infringement under the Hatch-Waxman Act. After a five-day bench...
