The American University Law Review recently published a very timely and compelling article on the intersection between the Hatch-Waxman Act and the BPCIA, on the one hand, and post-grant proceedings at the PATB, on the other.  The article, which is titled, Ships in the Night: Resolving Administrative Conflict Between FDA- and Patent-Related Legislation, American Univ. Law Review [Vol. 68:1111], (hereinafter, “Garcia & Stroud”), is authored by Carlos A. Garcia, Patent Counsel, Eli Lilly & Company, and Jonathan Stroud, Chief IP Counsel, Unified Patents Inc.  The article is a comprehensive and thorough overview of how petitions for inter partes review and other post-grant proceedings may be impacting efficient resolution of patent issues for generic drugs.

In an earlier post, we discussed the pending IPRs filed by Coherus Biosciences against Amgen’s two patents covering its Enbrel® protein (entanercept).  Whereas our earlier post summarized Coherus’s argument for why the fusion protein claimed in Amgen’s ‘182 and ‘522 patents should be found obvious by the PTAB, this post will summarize Amgen’s preliminary response.
