`Petition for Inter Partes Review of U.S. Patent No. 9,561,177
`INTRODUCTION
`
`I.
`
`Nalox-1 Pharmaceuticals, LLC (“Petitioner”) respectfully requests inter
`
`partes Review (“IPR”) of claims 1–30 (the “Challenged Claims”) of U.S. Patent No.
`
`9,561,177 (“the ’177 patent”), purportedly owned by Adapt Pharma Limited and
`
`Opiant Pharmaceuticals, Inc. (“Patent Owners”). For the reasons addressed below,
`
`the Challenged Claims should be found unpatentable and canceled.
`
`The ‘177 patent is listed in the FDA’s Approved Drug Products with
`
`Therapeutic Equivalence Evaluations (a.k.a. “The Orange Book”) as covering
`
`intranasal naloxone sold under the Narcan® name. Naloxone rapidly reverses opioid
`
`overdose -- it is an opioid antagonist and acts to restore normal respiration to a person
`
`whose breathing is impaired from opioid overdose. Naloxone has been available
`
`since 1971 as an injection, and its intranasal administration has been known in the
`
`community since at least 1994 as a safe and effective opiate overdose treatment.
`
`Loimer (Nalox1060) at 819. Narcan® is currently the only FDA-approved single-
`
`use nasal spray indicated for the emergency treatment of known or suspected opioid
`
`overdose. Because of the Patent Owners’ listing of patents in The Orange Book,
`
`there are currently no generic versions of intranasal Narcan® on the market. Patent
`
`Owners’ disingenuous use and abuse of the patent system here is contrary to the
`
`Constitution’s requirement to “promote the progress of science and useful arts” by
`
`1
`
`
`
`IPR2019-00693
`Petition for Inter Partes Review of U.S. Patent No. 9,561,177
`wrongfully monopolizing access to life-saving medicine until 2035, based on
`
`generations-old science and the most obvious applications in this art.
`
`The United States is in the throes of an opioid epidemic. According to the
`
`Centers for Disease Control and Prevention, on average, 130 Americans die each
`
`day from an opioid overdose, and in 2017, the number of overdose deaths involving
`
`opioids was six times higher than in 1999. There is a critical and urgent need in
`
`America for intranasal naloxone products intended for community use and which
`
`can be deployed in life-threatening circumstances -- often by people who are not
`
`medically trained. America cannot afford to wait another day for affordable, safe
`
`and effective intranasal naloxone. The ’177 patent is a barrier wrongfully and
`
`shamefully preventing broader accessibility to this critically needed naloxone
`

`Petition for Inter Partes Review of U.S. Patent No. 9,561,177
`Statement of Non-Redundancy
`
`2.
`
`This is Petitioner’s first challenge relating to the ’177 patent before the Board.
`
`Petitioner submits the grounds provided in this Petition are not redundant nor
`
`duplicative of the grounds previously presented to the Office during the examination
`
`of the ’177 patent.
`
`Petitioner respectfully submits new evidence and arguments provided here are
`
`not “the same or substantially the same” previously considered by the Office. When
`
`evaluating whether previously presented prior art or arguments are “the same or
`
`substantially the same,” the Board examines several non-exclusive factors to guide
`
`its decision under 35 U.S.C. §325(d). The non-exclusive factors, also referred to as
`
`the “Becton Dickinson factors” are:
`
`(a) the similarities and material differences between the
`asserted art and the prior art involved during examination;
`(b) the cumulative nature of the asserted art and the prior
`art evaluated during examination;
`(c) the extent to which the asserted art was evaluated
`during examination, including whether the prior art was
`the basis for rejection;
`(d) the extent of the overlap between the arguments made
`during examination and the manner in which Petitioner
`relies on the prior art or Patent Owner distinguishes the
`prior art;
`(e) whether Petitioner has pointed out sufficiently how the
`Examiner erred in its evaluation of the asserted prior art;
`and
`
`4
`
`
`
`IPR2019-00693
`Petition for Inter Partes Review of U.S. Patent No. 9,561,177
`(f) the extent to which additional evidence and facts
`presented in the Petition warrant reconsideration of the
`prior art or arguments.
`Becton, Dickinson & Co. v. B. Braun Melsungen AG, IPR2017-01586, Paper 8 at
`
`17–18 (PTAB Dec. 15, 2017).
`
`Becton Dickinson factors (a), (b), and (c), which analyze the cumulative or
`
`overlapping nature of the proceedings, support institution here. While primary
`
`reference Wyse (in combination with a secondary reference, Djupesland1) was cited
`
`by the Examiner in a rejection of certain claims during the prosecution of the ’177
`
`patent, HPE was not a reference of record.2 Thus, the Petition’s combination of
`
`Wyse and HPE, which together, or in combination with certain additional references,
`
`renders obvious the challenged claims, was never evaluated during examination.
`
`This Petition thus presents non-cumulative grounds and arguments not presented
`
`during prosecution.
`
`Remaining Becton Dickinson factors (d), (e), and (f) also strongly support
`
`institution. Those factors analyze whether the Petitioner has sufficiently made a case
`
`for reconsidering the prior art. Where the Petition “sufficiently shows that the
`
`Examiner’s decision not to reject the claims” was “based on an erroneous finding by
`
`
`
` 1
`
` The Djupesland reference cited during prosecution is the same reference included
`in Grounds 3 and 6-10 of this Petition.
`2 HPE is not cumulative to any reference cited during the prosecution of the ’177
`patent.

`
`
`
`IPR2019-00693
`Petition for Inter Partes Review of U.S. Patent No. 9,561,177
`the Examiner,” particularly regarding the prior art’s disclosure, institution is
`
`warranted. See Black & Decker (U.S.) Inc. v. Christy, Inc., IPR2015-00468, Paper
`
`13 at 13 (PTAB June 24, 2015). Further, where the Petition is supported by evidence
`
`that was not available in prosecution that further elucidates what a POSA would
`
`have understood from a reference’s disclosure, Becton-Dickinson factors (d)–(f)
`
`support institution. See Parsons XTreme Golf v. Taylor Made Golf Co., PGR2018-
`
`00074, Paper No. 7 at 43 (PTAB, Jan. 24, 2019). Here, the Examiner erred in finding
`
`Wyse teaches away from the use of one of the claimed ingredients, benzalkonium
`
`chloride (BAC). See Notice of Allowance, (Nalox1006) at 8). As Petitioner shows
`
`in this Petition, and as supported by the Declarations of Dr. Donovan and Dr.
`
`Hochhaus, HPE would have motivated a POSA to use BAC, and a POSA would not
`
`have considered Wyse to teach away from its use in the claimed naloxone solution.
`
`Thus, this Petition presents new evidence and testimony not previously available to
`
`the Examiner during prosecution. In view of the above, Petitioner respectfully
`
`requests the Board decline to use its discretion under 35 U.S.C. §325(d).

`
`Relief Requested
`
`
`
`Petitioner requests the Board cancel the Challenged Claims as being
