`
`
`
`INTRODUCTION
`
`Patent Owner Preliminary Response
`
`
`United Therapeutics Corporation (“UT”) requests that the Board deny the
`
`Petition, filed by Liquidia Technologies, Inc. (“Liquidia”), for inter partes review
`
`of claims 1-10 (“Challenged Claims”) of U.S. Patent No. 9,593,066 (“the ’066
`
`patent”) for two primary reasons.
`
`First, the Board should exercise its discretion under §325(d) to deny
`
`institution because Liquidia relies on the identical art considered in detail during
`
`examination and nearly identical arguments already considered by the examiner.
`
`Liquidia offers no explanation of Office error, beyond more disagreement with the
`
`Office’s prior reasoning and conclusions regarding this art and arguments.
`
`Second, Liquidia’s arguments ignore different claim limitations and rely on
`
`technical inaccuracies in an effort to leverage the cancelation of the claims of the
`
`parent patent. Thus, the Petition fails to establish a reasonable likelihood that
`
`Liquidia would prevail and should be denied. While UT has no burden to establish
`
`patentability, the testimony of its expert, Dr. Rodolfo Pinal (Ex. 2002, ¶¶1-314),
`
`and supporting Exs. 2003-2006, 2008-2012, and 2016, as discussed below provide
`
`additional evidence against Liquidia’s arguments.

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
` THE ’066 PATENT
`
`Patent Owner Preliminary Response
`
`
`Each of the claims in the ’066 patent defines a pharmaceutical composition
`
`or process of preparing pharmaceutical products containing treprostinil or a
`
`pharmaceutically acceptable salt thereof. Ex. 1001, 12; Ex. 2002, ¶¶46-53.
`
`Treprostinil is the active ingredient in three Food and Drug Administration-
`
`approved drugs: Remodulin® (treprostinil) Injection, Tyvaso® (treprostinil)
`
`Inhalation Solution, and Orenitram® (treprostinil) Extended-Release Tablets.
`
`The ’066 patent includes two independent claims. Claim 1 defines a
`
`pharmaceutical composition comprising treprostinil or a pharmaceutically
`
`acceptable salt prepared by a defined process from a starting batch of treprostinil
`
`having one or more impurities resulting from prior alkylation of benzindene triol
`
`and hydrolysis steps. Claim 1 has purity requirements relative to the starting batch.
`
`Ex. 2002, ¶¶46, 49, 51. Claims 2-7 depend from claim 1. Ex. 2002, ¶47. Claim 8
`
`defines a process of preparing a pharmaceutical product comprising treprostinil or
`
`a pharmaceutically acceptable salt thereof, comprising five steps including:
`
`(1) alkylating, (2) hydrolyzing, (3) forming, (4) storing, and (5) subsequently
`
`preparing the pharmaceutical product. Ex. 2002, ¶¶48-49, 52. Claims 9 and 10
`
`depend from claim 8. Id., ¶53.

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`Despite Dr. Winkler’s assertion that claim 8 is simply the process of
`
`preparing the pharmaceutical composition of claim 1, Ex. 1002, ¶¶26-27, this
`
`assertion is plainly wrong. Claim 1 defines a pharmaceutical composition prepared
`
`by a process with limitations specifying the impurity of a starting batch, isolation
`
`of a treprostinil salt, and the resulting purer product. By contrast, claim 8 defines a
`
`process for preparing a pharmaceutical product with temperature and storage
`
`limitations. Ex. 2002, ¶¶48-52. Although the claims have some limitations in
`
`common, Liquidia fails to account for key differences, a failing repeated in the
`
`obviousness analysis.
`
`Similarly, Dr. Winkler asserts that the challenged claims are “substantially
`
`similar” to the claims of the parent patent, U.S. Patent No. 8,497,393 (“’393
`
`patent”), but this assertion is also facially wrong. Ex. 1002, ¶¶36-37; Ex. 2002,
`
`¶¶72-83. The ’393 patent presented claims generally directed to the total synthesis
`
`of treprostinil and “[a] product comprising” treprostinil. Ex. 1004, 17:52-21:16.
`
`The ’066 patent claims define pharmaceutical compositions and pharmaceutical
`
`products with specific limitations regarding stability, storage, and purity. Ex. 1001,
`
`17:51-63; see also id., 18:34-35, 18:38-61 (claims 6 and 8, with limitations related
`
`to API storage), 18:36-37 (claim 7, reciting a “pharmaceutical solution”), 18:38-66
`
`(claims 8-10, reciting a “pharmaceutical product”); Ex. 2002, ¶¶74-79.

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`Liquidia fails to identify a ’393 patent claim with limitations like those of
`
`challenged claim 1 requiring a pharmaceutical composition comprising a
`
`treprostinil active pharmaceutical ingredient (API) that is purer than a starting
`
`batch of treprostinil. The person of ordinary skill in the art (“POSA”) would have
`
`understood that the ’066 patent is focused on the production of pharmaceutical
`
`compositions and products on a batch-size scale, not merely synthesizing
`
`treprostinil. Ex. 2002, ¶¶87-89, 91, 136-140.
`
` CLAIM CONSTRUCTION
`
`Claim construction requires assigning a meaning that the term would have
`
`had to the POSA at the time of the invention (here, December 17, 2007). 37 C.F.R.
`
`§42.100(b); Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en
`
`banc); Ex. 2002, ¶¶45, 102-03. A claim must be construed in light of the
`
`specification, including the disclosed purpose of the invention. United States v.
`
`Adams, 383 U.S. 39, 48-49 (1966) (error to interpret claims apart from disclosed
`
`purpose). Though its own expert offers none (see Ex. 1002, ¶35), Liquidia offers
`
`several claim constructions that fail to meet this standard. Pet.18-19; Ex. 2002,
`
`¶¶104-105.

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`A. “Pharmaceutical Product”
`
`Patent Owner Preliminary Response
`
`
`Liquidia improperly construes “pharmaceutical product” to exclude
`
`“pharmaceutical.” Pet.17 (proposing a construction of “chemical composition” for
`
`both “product” and “pharmaceutical product”). Claim 8 is directed to a “process of
`
`preparing a pharmaceutical product….” Yet Liquidia asserts that “pharmaceutical
`
`product” meant “a chemical composition” broadly, without regard to impurities or
`
`other components within the composition or the requisites for a useful
`
`“pharmaceutical” product. Ex. 2002, ¶106; see also Ex. 1005, 16-17 (noting, in
`
`contrast, that the ’393 patent claims did not “disavow the full scope of the term
`
`‘product’). Liquidia offers conclusory statements rather than intrinsic evidence to
`
`avoid applying the plain and ordinary meaning. The POSA would have understood
`
`“pharmaceutical product” to mean a chemical composition suitable for
`
`pharmaceutical use. Ex. 2002, ¶¶107-09, citing Ex. 1001, 5:13-17 (defining
`
`“pharmaceutically acceptable”), 5:18-20 (defining “pharmaceutically acceptable
`
`salts”), & Ex. 2004, 133 (defining “drug product”).
`
`B. “A Pharmaceutical Composition Comprising Treprostinil or a
`Pharmaceutically Acceptable Salt Thereof”
`
`Liquidia next exploits its overbroad definition of “product” to argue that the
`
`claims include a “compound of treprostinil or a pharmaceutically acceptable salt
`
`
`
`4818-3909-1139.1
`
`5
`
`

`

`Case IPR2020-00769

`
`Patent Owner Preliminary Response
`
`
`thereof, and that may also include other non-mentioned substances (including
`
`impurities), additives, or carriers, without limitation as to the types or relative
`
`amounts thereof.” Pet.18; Ex. 2002, ¶110. Again, Liquidia’s construction ignores
`
`the pharmaceutical limitation in “pharmaceutical composition,” effectively
`
`rendering the term meaningless.
`
`Although the transitional phrase “comprising” is open, it is not without
`
`limitation because the resulting composition must be pharmaceutically acceptable.
`
`Ex. 2002, ¶¶110-112. Griffin v. Bertina, 285 F.3d 1029, 1033 (Fed. Cir. 2002)
`
`(affirming Board construction requiring steps relate to diagnosis as provided in
`
`preamble). The POSA would have understood the plain and ordinary meaning of
`
`“a pharmaceutical composition comprising treprostinil or a pharmaceutically
`
`acceptable salt thereof” to be a composition comprising treprostinil or a
`
`pharmaceutically acceptable salt thereof that is suitable for pharmaceutical use.
`
`Similarly, the use of “comprising” with the process limitations is not
`
`“without limitation,” Pet.18, because the claims include further limitations
`
`requiring the resulting product be pharmaceutically acceptable. Ex. 2002, ¶¶113-
`
`116, citing Ex. 1005, 19 (noting Liquidia’s proposed “without limitation”
`
`construction is even broader than that found for a “process comprising” claim
`
`limitation in the ’393 IPR under BRI).

`Patent Owner Preliminary Response
`
`
`C. Additional terms require construction
`
`1. Starting Batch
`
`Claim 1 includes the term “starting batch.” Ex. 1001, 17:51-63 (claim 1); see
`
`also id., 17:64-18:37 (claims 2-7). This starting batch is further processed into the
`
`pharmaceutical composition of claim 1. Id.; Ex. 2002, ¶117. The term “starting
`
`batch” limits claim 1 to a specific material, used in the production of the claimed
`
`pharmaceutical composition. Ex. 2002, ¶¶118-119, citing 21 C.F.R. §210.3 (April
`
`1, 2007 ed.) (Ex. 2004), 133 (defining an in-process material as “any material
`
`fabricated, compounded, blended, or derived by chemical reaction that is produced
`
`for, and used in, the preparation of the drug product”).
`
`FDA defines “batch” in a pharmaceutical-process context as meaning “a
`
`specific quantity of a drug or other material that is intended to have uniform
`
`character and quality, within specified limits, and is produced according to a single
`
`manufacturing order during the same cycle of manufacture.” Ex. 2004, 133 and
`
`also 134 (defining the word “lot” to mean “a batch, or a specific identified portion
`
`of a batch, having uniform character and quality within specified limits”); Ex.
`
`2002, ¶120.
`
`The POSA viewing the ’066 patent claims in light of the ’066 patent
`
`specification would have understood claim 1’s “starting batch” to be a specific
`
`
`
`4818-3909-1139.1

`
`

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`quantity of treprostinil that is intended to have uniform character and quality,
`
`within specified limits, and is produced according to a single manufacturing order
`
`during the same cycle of manufacture, wherein the uniform character and quality is
`
`such that the starting batch comprises a level of impurities that is higher than the
`
`final batch of treprostinil API used in the formulation of the claimed
`
`pharmaceutical composition. Ex. 2002, ¶¶121. Neither Phares nor Moriarty teaches
`
`this limitation. Ex. 2002, ¶122.
`
`2. Stored, Storing, Storage
`
`Dependent claim 6 recites the “pharmaceutical composition of claim 1,
`
`wherein the isolated salt is stored at ambient temperature.” Ex. 1001, 18:35-36.
`
`Process claim 8 requires “storing” and “storage” of the produced treprostinil salt.
`
`See Ex. 1001, 18:38-61 (claim 8); see also id., 18:62-66 (dependent claims 9-10).
`
`The POSA would have understood these terms to require stability of the material
`
`being stored. Ex. 2002, ¶¶123-24. As the ’066 patent specification explains,
`
`“stable” compounds are those “which possess stability sufficient to allow
`
`manufacture and which maintain the integrity of the compound for a sufficient
`
`period of time to be useful for the purposes detailed herein.” Ex. 1001, 4:57-63.
`
`Thus, claims 8-10 require the treprostinil salt to be “stable at ambient

`
`
`temperature,” and claims 6 and 8-10 further require that the material being stored
`
`be stable upon storage such that the stored material maintains integrity for a
`
`sufficient period of time to be useful for the claimed “pharmaceutical” purposes.
`
`This required stability is formulation-specific and not a trivial matter—
`
`especially when working with polymorphic salts. Ex. 2002, ¶126. The POSA
`
`viewing the ’066 patent claims in light of the ’066 patent specification would have
`
`understood “stored,” “storage,” and “storing” to require that the stored material
`
`possesses stability sufficient to allow manufacture and which maintains integrity
`
`for a sufficient period of time to be useful for the preparation of a pharmaceutical
`
`composition or a pharmaceutical product. Ex. 2002, ¶126.
`
` THE BOARD SHOULD DENY INSTITUTION UNDER § 325(d)
`
`The Office considered prior art identical to Liquidia’s—and arguments
`
`nearly identical to Liquidia’s—during the ’066 patent’s examination. Indeed,
`
`Liquidia leans hard on an IPR against U.S. Patent No. 8,497,393 (IPR2016-00006;
`
`hereinafter “’393 IPR”) resulting in cancelation of the parent ’393 patent claims.
`
`Liquidia uses the same art, arguments, and even the same expert expressing the
`
`same opinions. E.g., Pet.19 (“[S]ince the claim limitations of the ’066 patent are
`
`substantively similar to the invalidated ’393 patent, the ’066 patent should be
`
`
`
`4818-3909-1139.1
`
`9
`
`

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`similarly declared invalid.”). Yet UT submitted the ’393 IPR art and arguments to
`
`the examiner, who considered them yet allowed the ’066 patent in view of the
`
`different claim limitations.
`
`Liquidia clearly disagrees with the Office’s prior weighing and consideration
`
`of that evidence and argument, but Liquidia fails to identify any error the Office
`
`committed beyond merely disagreeing with the result. Indeed, Liquidia’s
`
`arguments assume a false equivalency between the Challenged Claims and the
`
`’393 patent claims. The examiner instead carefully considered the evidence and
`
`arguments in light of the claim limitations—many of which Liquidia ignores or
`
`grossly distorts—and issued the challenged claims over Liquidia’s prior art and
`
`arguments. Thus, the Board should exercise its discretion under 35 U.S.C. § 325(d)
`
`to deny institution against the ’066 patent.
`
`A. The Advanced Bionics Two-Part Framework
`
`Under Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte
`
`GmbH, the Board applies a two-part framework when evaluating whether to
`
`exercise its discretion under § 325(d). IPR2019-01469, Paper 6 (Feb. 13, 2020)
`
`(precedential)(hereinafter “Advanced Bionics”). In applying this framework, the
`
`Board considers: (1) whether the same or substantially the same art previously was
`
`
`
`4818-3909-1139.1
`
`10
`
`

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`presented to the Patent Office or whether the same or substantially the same
`
`arguments previously were presented to the Office; and (2) if either condition of
`
`first part of the framework is satisfied, whether the petitioner has demonstrated that
`
`the Office erred in a manner material to the patentability of challenged claims. Id.
`
`“If a condition in the first part of the framework is satisfied and the petitioner fails
`
`to make a showing of material error, the Director generally will exercise discretion
`
`not to institute inter partes review.” Id. at 8-9 emphasis added). The Becton,
`
`Dickinson factors “provide useful insight into how to apply the framework under
`
`35 U.S.C. § 325(d).” Id. at 9-11.
`
`Prior consideration of the same or substantially the same prior art or
`
`arguments is sufficient for the Office to exercise its discretion to decline review.
`
`Id.; §325(d)(written in the disjunctive); Puma v. Nike, IPR2019-01042, Paper 10
`
`(informative) (denying institution under § 325(d) where petition relied upon same
`
`combination of art that Examiner applied in original prosecution even though
`
`petitioner “provide[d] new evidence and argument”) (hereinafter “Puma”). Thus,
`
`evaluation of step 2 is appropriate based on sufficiently similar prior art or
`
`arguments.

`
`

`

`Case IPR2020-00769
`Patent 9,593,066

`
`
`“If reasonable minds can disagree regarding the purported treatment of the
`
`art or arguments, it cannot be said that the Office erred in a manner material to
`
`patentability.” Id. at 9.
`
`B. Liquidia Relies on the Same Art (Becton Factors (a) & (b))
`
`The Office already considered Liquidia’s prior art during examination of the
`
`application that issued as the ’066 patent. Ex. 2002, ¶¶57-62, 250. Liquidia asserts
`
`only two references: Moriarty and Phares. Pet.3. The prosecution history explicitly
`
`shows these references were considered, as the following table illustrates:

`

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`This reliance on the same prior art is enough to meet the first prong under
`
`the Advanced Bionics framework. Advanced Bionics at 9; Puma v. Nike, IPR2019-
`
`01042, Paper 10 (informative) (denying institution where petition relied upon the
`
`art combination applied in original examination even though petitioner “provide[d]
`
`new evidence and argument”) (“Puma”).
`
`Surprisingly, Liquidia asserts that “[t]his Petition does not present a scenario
`
`in which ‘the same or substantially the same prior art or arguments previously were
`
`presented to the Office.’” Pet.3. Yet the examiner explicitly applied—then
`
`withdrew—these very references, as Liquidia admits. Id. at 4 (“the Examiner
`
`considered both Moriarty (Ex. 1009) and Phares (Ex. 1008) and relied upon these
`
`two prior art references in issuing a rejection of all claims of the ’066 patent under
`
`35 U.S.C. § 103(a)”).
`
`Liquidia disparages the examiner’s understanding of these references. Pet.4.
`
`Yet these are references that Liquidia states a chemistry sophomore would
`
`understand. Id. 36, 64; cf. American Hoist & Derrick Co. v. Sowa & Sons, 725 F.2d
`
`1350, 1359 (Fed. Cir. 1984) (examiner presumed to have properly examined). UT
`
`even referenced the competing experts’ views of the references in responding to a
`
`rejection based on Moriarty and Phares. Ex. 2006, 3788-3794. Thus, the examiner
`
`knew of, considered, and even applied the very information from the ’393 IPR that
`
`13
`
`4818-3909-1139.1
`
`

`

`Case IPR2020-00769
`Patent 9,593,066
`
`
`
`Patent Owner Preliminary Response
`
`
`Liquidia asserts is dispositive here. Ex. 2002, ¶¶68-83. The purported
`
`misunderstanding is simply Liquidia’s disagreement with the examiner’s
`
`conclusion.
`
`Moreover, the Office also previously considered the same or substantially
`
`the same evidence beyond Moriarty and Phares that Liquidia relies on here as
`
`shown in Table 2:
