Final Written Decisions

In the chemical and biological arts, it is common for patent challengers to allege obviousness based upon prior art disclosures of ranges combined with “routine optimization” by one skilled in the art.  In E.I. du Pont de Nemours & Co. v. Synvina C.V., No. 17-1977 (Fed. Cir. Sept. 17, 2018), the Federal Circuit reversed the PTAB’s (“Board”) final written decision upholding Synvina’s U.S. Patent No. 8,865,921 (“’921 patent”) as non-obvious, in response to du Pont’s inter partes review (“IPR”) challenge on such grounds.  In particular, in E.I. du Pont, the Court found that the patentee failed to demonstrate that 1) the claimed range produced a new and unexpected result, different in kind and not merely in degree from the prior art, 2) the optimized parameter was not recognized as a result-effective variable, 3) the disclosure of broad ranges did not invite more than routine optimization, or 4) that the prior art taught away from the range.

The Federal Circuit recently held that a product catalog distributed at a trade show was “publicly accessible,” and therefore qualified as prior art. In Nobel Biocare Services AG, v. Instradent USA, Inc., decided on September 13, 2018, the Federal Circuit affirmed the Patent Trial and Appeal Board’s (“PTAB”) finding that a catalog distributed at the International Dental Show (“IDS”) Conference in Cologne, Germany was publicly accessible. The court’s decision in Nobel hinged largely on the testimony of two declarants, one who went to the conference (Zvi Chakir), and another who Chakir gave the catalog to upon his return (Yechiam Hantman).

During the week of August 6, the Board issued nine decisions in Technology Center 1600, two denying institution of IPR, two Final Written Decisions finding the challenged claims not unpatentable, two Final Written Decisions finding the challenged claims unpatentable, and two terminating inter partes review (“IPR”) proceedings, in whole or in part.  The decisions follow.

On July 13, 2018, in Jazz Pharms., Inc. v. Amneal Pharms., LLC, (Case Nos. 2017-1617, -1673, -1674, -1675, -1676, -1677, -2075), the Federal Circuit affirmed the Patent Trial and Appeal Board’s (“PTAB”) holding that certain FDA advisory meeting minutes, transcripts, and slides were publicly available such that the materials constituted prior art.  We have previously discussed the PTAB’s public availability jurisprudence in Coalition for Affordable Drugs VIII, LLC v. The Trustees of the University of Pennsylvania, IPR2015-01835 where the PTAB held a presentation given to investors was not prior art.

During the week of July 9, the Board issued four decisions in Technology Center 1600, three decisions denying institution of inter partes review and one Final Decision finding the challenged claims patentable. In addition to these four decisions the Board, in ABS Global, Inc. v. XY, LLC, No. IPR2017-02184, also granted Patent Owner’s request for an adverse judgement. The four decisions are as follows:

Drug product labels (also known as prescribing information) are often asserted as prior art by patent challengers, both in front of the PTAB and in district court ANDA litigation.  Before the PTAB, using such prior art requires showing that it qualifies as a “printed publication” under 35 U.S.C. §§ 102 and 311(b).  Recently, the PTAB appears to be applying greater scrutiny to the use of such prior art when cited in invalidity grounds.  The Board’s analysis in such situations “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.”  Sandoz Inc. v. AbbVie Biotechnology Ltd., IPR2018-00156, Paper 11 at *9 (June 5, 2018) (citing In re Klopfenstein, 380 F.3d 1345, 1350 (Fed. Cir. 2004)).  A pair of recent rulings identify some of the evidentiary issues catching the eyes of PTAB panels as they consider invalidity arguments that rely on product-label prior art.
