`
`
`
`
`Petitioner Amneal Pharmaceuticals LLC ("Amneal") submits this Reply to
`
`Patent Owner Supernus Pharmaceuticals, Inc.’s ("Supernus") Response to the
`
`Petition filed by Amneal concerning claims 1, 2, 5-15 and 19-22 of U.S. Patent
`
`No. 8,206,740 ("the '740 patent"). As set forth in detail below, Supernus has failed
`
`to rebut Amneal's showing that the foregoing claims of the '740 patent would have
`
`been obvious in view of (1) International Publication No. WO 02/080932 ("Ashley
`
`'932")[ Ex. 1002] (incorporating by reference U.S. Provisional Patent Application
`
`No. 60/281,854 ("Ashley '854") [Ex. 1003]) combined with (2) U.S. Patent
`
`No. 5,348,748 ("Sheth") [Ex. 1005].
`
`I.
`
`
`
`SUPERNUS HAS NOT REBUTTED AMNEAL'S SHOWING OF
`OBVIOUSNESS
`
`A. Ashley '932 Teaches IR/DR Formulations of Doxycycline
`
` The Petition demonstrated that Ashley '932 teaches an IR/DR formulation.
`
`Paper 2 at 8-13. Ashley '932, by its incorporation of the Ashley '854, teaches
`
`formulations comprising "a controlled release agent selected from the group
`
`consisting of an instantaneous release agent, a sustained-release agent, a delayed-
`
`release agent, and combinations thereof." Ex. 1003 at 5:24-26. The Board cited this
`
`language in holding that Ashley '854 discloses an IR/DR-only formulation (among
`
`others). Paper 8 at 8.
`
`Supernus and its expert, Dr. Edward Rudnic, insist that Ashley '854 requires
`
`a sustained-release agent in all embodiments. Paper 39 at 11-12. During his
`
`- 1 -
`
`
`
`
`
`deposition, Dr. Rudnic criticized the Board's "very narrow interpretation" of the
`
`Ashley '854 reference based on its recitation of an IR/DR only formulation as one
`
`of seven possible combinations; but then Dr. Rudnic inexplicably insisted that the
`
`Ashley reference does not disclose an IR/DR combination. Ex. 1052 at 102:10-22;
`
`97:23-99:3. When pressed to explain his rationale, Dr. Rudnic repeatedly asserted
`
`that the "central theme" or "central focus" is a substantially constant rate of release.
`
`Id. at 79:7-81:15.
`
`But that is not the law. It is well settled that "[a] reference may be read for
`
`all that it teaches, including uses beyond its primary purpose" and not just its
`
`"central focus" or "central theme" as Supernus and Dr. Rudnic insist. In re Mouttet,
`
`686 F.3d 1322, 1331 (Fed. Cir. 2012). As the Board previously noted, "[t]hat
`
`Ashley '854 devotes more attention to formulations including sustained-release
`
`agents than to others is irrelevant." Paper 8 at 12. Dr. Rudnic also emphasizes the
`
`absence of working examples of formulations in Ashley '854. See, e.g., Ex. 2016 at
`
`¶ 126. But the law does not require working examples; prior art "is relevant for all
`
`it contains." In re Heck, 699 F.2d 1331, 1332-33 (Fed. Cir. 1983).
`
`B. Galderma — A Real Party In Interest — Adopted Petitioner's
`View of the Disclosure of the Ashley '854 Application
`
`Supernus' insistence that Ashley '854 must always include an SR component
`
`
`
`is directly refuted by statements made by Galderma—a real party in interest in this
`
`proceeding—during prosecution of U.S. Application No. 10/474,240 (which
`
`- 2 -
`
`
`
`
`
`claims priority to Ashley '854 and has a nearly identical specification). During the
`
`'240 application's prosecution, Galderma argued that the very language cited by the
`
`Petitioner and Board, i.e. "a controlled release agent… consisting of an
`
`instantaneous release agent, sustained-release agent, a delayed-release agent and
`
`combinations thereof" supported a claim for an IR/DR only dosage form. Ex. 1020
`
`at 3-4, citing Ex. 1092 at 9-10. Indeed, it insisted that the Ashley invention
`
`"cannot include a prolonged release agent." Id. at 4 (emphasis in original).
`
`As a real party in interest, Galderma's representations concerning Ashley
`
`'854's disclosure are relevant evidence of the prior art and a POSA's understanding
`
`thereof. See Abbott Labs. v Andrx Pharm., Inc., 452 F.3d 1331,1341 (Fed. Cir.
`
`2006). Dr. Rudnic testified that he did not consider this Galderma admission in
`
`forming his opinions. Ex. 1052 at 77:12-15. Supernus now argues to the Board that
`
`Ashley '854 must include a sustained release agent in any combination; but the real
`
`party in interest, Galderma, argued the exact opposite to the Patent Office.
`
`C. A Skilled Artisan Would Have Combined the Teachings of the
`Prior Art at Issue
`
`As the Board correctly noted, "Amneal relies on Sheth merely for its
`
`
`
`disclosure concerning the ratio of immediate release pellets to delayed release
`
`pellets." Paper 8 at 12. As an initial matter, Supernus has not rebutted—and cannot
`
`rebut—the disclosure in Sheth that includes the claimed ratio of 30 mg IR to 10 mg
`
`DR. Dr. Rudnic criticizes the combination of Ashley '932 and Sheth on the basis
`
`- 3 -
`
`
`
`
`
`that such a combination would not "necessarily be successful." Ex. 2016, ¶¶ 56, 58.
`
`But obviousness requires only a reasonable expectation of success, not certainty or
`
`necessary success. Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir.
`
`2007). Dr. Rudnic admitted that he did not know if the "necessarily successful"
`
`standard he relied on in his declaration was the correct standard for obviousness.
`
`Ex. 2016, ¶56, 58; Ex. 1052, 47:12-16.
`
`Supernus argues that a POSA would not combine Ashley and Sheth because
`
`Ashley teaches low plasma levels of doxycycline and Sheth teaches antimicrobial
`
`levels of minocycline. Paper 39 at 25-26. As set forth in the Petition (at 23-27),
`
`however, a POSA would have looked to a reference such as Sheth if a POSA
`
`needed further guidance regarding IR/DR ratios to develop a formulation achieving
`
`the plasma concentrations taught by Ashley '932. In its Decision (at 12), the Board
`
`accepted Petitioner's argument, "that the otherwise close relatedness of these two
`
`drugs [i.e. doxycycline and minocycline] in structure and function makes
`
`information about formulation of one relevant to formulation of the other."
`
`Doxycycline and minocycline are closely-related in terms of chemical
`
`structure, pharmacokinetics, and therapeutic properties as Dr. Glenn Van Buskirk,
`
`Amneal's pharmaceutical formulation expert, explains in his declaration. Ex. 1022,
`
`¶185. While some differences exist, they are not so great that a POSA would
`
`ignore minocycline art as guidance on doxycycline. Ex. 1066, ¶¶ 56-62.
`
`- 4 -
`
`
`
`
`
`In fact, Ashley '932 itself expressly states that doxycycline and minocycline
`
`are useful for treating rosacea, providing another reason for a POSA to combine
`
`Ashley with Sheth. Ex. 1002 at 7:24-25. And Sheth is concerned with achieving a
`
`once-daily administration of minocycline, a further reason to combine Sheth with
`
`Ashley. Moreover, Dr. Rudnic's own patent, which published as US 2002/0136766
`
`A1 prior to the '740 patent filing date, teaches tetracycline IR/DR formulations that
`
`would be suitable for both doxycycline and minocycline. Accordingly, the Board
`
`should give little weight to his testimony that minocycline formulations are
`
`irrelevant. Compare Ex. 2016, ¶ 137-41 with Ex. 1089, Ex. 1032, claims 1 & 2,
`
`and Ex. 1052 at 143:21-25.
`
`Armed with what was known about the absorption properties of
`
`doxycycline, a POSA would have at least a reasonable expectation of success that
`
`an IR/DR formulation would be a successful strategy to achieve once-daily dosing
`
`of doxycycline. See Ex. 1066, ¶68; Ex. 2016, ¶50. This expectation is supported by
`
`the teachings of Sheth, which showed that an IR/DR combination is useful for
`
`once-daily dosing of minocycline which, like doxycycline, was known to be
`
`absorbed in the upper gastrointestinal tract. Ex. 1066, ¶¶51, 68. And it is further
`
`supported by the knowledge in the art that both IR and DR doxycycline products
`
`were in use. Id., ¶75; Ex. 1068, 95:2. Whether a POSA would be aware that
`
`doxycycline may have lower absorption below the duodenum is of no moment
`
`- 5 -
`
`
`
`
`
`because a POSA would know that doxycycline is absorbed in the duodenum, and
`
`could therefore reasonably expect to formulate successful IR/DR dosages. Ex.
`
`1066, ¶¶ 51, 66-71. Supernus suggests that it would require too much trial and
`
`error for a POSA to achieve a successful doxycycline formulation based on Ashley
`
`'932 and Sheth. Paper 39 at 38-40. But preparing prototype formulations and
`
`conducting routine testing to evaluate those formulations would be well within the
`
`skill and ability of a POSA. Ex. 1022, ¶¶ 177, 184; Ex. 1066 at Table 3 at 14.
`
`
`
`D. The Art as a Whole Does Not "Teach Away"
`
`Supernus argues that Ashley '932 and Sheth "teach away" from the IR/DR
`
`formulations claimed by the '740 patent. Paper 39 at 21-23. For art to "teach
`
`away," it must "criticize, discredit, or otherwise discourage the solution claimed."
`
`In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). But there are no teachings in
`
`any of the art of record that remotely criticize, discredit, or discourage IR/DR
`
`formulations. The mere fact that Ashley '932 identifies another embodiment as
`
`preferred is not a "clear discouragement." Santarus, Inc. v. Par Pharm., Inc., 694
`
`F.3d 1344, 1356 (Fed. Cir. 2012). Moreover, Dr. Rudnic offered no evidence that
`
`the art as a whole teaches away; indeed his own prior art patent application recited
`
`the use of IR/DR formulations to deliver doxycycline. Ex. 1089. Dr. Rudnic's
`
`"teaching away" allegations are, ironically, contradicted by his own prior art.
`
`As set forth in the Petition (at 25), Sheth discloses a formulation with two
`
`- 6 -
`
`
`
`
`
`pulses: an IR pulse provided by an initial loading portion and a DR pulse provided
`
`by a secondary loading portion. Sheth teaches that the "second pulse provides a
`
`delayed release and a controlled release of [drug], preferably in the duodenum."
`
`Ex. 1005, 7:34-36 (emphasis added); Ex. 1066, ¶51. The second pulse has a "rapid
`
`and substantially complete release" in a buffer "having a pH of from about 4.5 to
`
`6.5" Id., 8:40-47.
`
`Dr. Rudnic conceded that there would be a "lag" associated with the initial
`
`release of drug from the Sheth secondary loading component. Ex. 1052 at 247:20-
`
`248:5. But he disputes that this is delayed release because it releases "a small
`
`amount of drug in the stomach" before a complete release "in the human upper
`
`intestinal tract and particularly in the duodenum." Ex. 1005, 7:14-21. This attempt
`
`to mischaracterize Sheth's express language reciting a delayed release portion as a
`
`"modified release or a short sustained release" system also fails. Ex. 2016, ¶180.
`
`Nowhere do the Sheth inventors describe their embodiments using this
`
`terminology. Ex. 1066, ¶¶39-40; 52-55.
`
`Even if Supernus' unduly narrow construction of delayed release is credited,
`
`the combination of Ashley '932 and Sheth still teaches a delayed release portion.
`
`Indeed, Supernus admits that "delayed-release agents" are disclosed by Ashley
`
`'854. See Paper 39 at 13. Consequently, there is no dispute that the art of record
`
`discloses DR dosage forms. Ex. 1022, ¶227.
`
`- 7 -
`
`
`
`
`
`E.
`
`The Claimed IR/DR Ratio Is Not Critical
`
`Supernus argues that its claimed ratio of 30 mg IR to 10 mg DR is critical.
`
`Paper 39 at 43. Here again, Supernus misapplies the law. "Only if the results of
`
`optimizing a variable are unexpectedly good can a patent be obtained for the
`
`claimed critical range." In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997).
`
`Supernus has not shown that its alleged "critical" ratio yields unexpectedly good
`
`results. Supernus merely alleges that the claimed ratio "best stays within the steady
`
`state blood levels . . . for as many patients as possible. . . ." Paper 39 at 43.
`
`Supernus has made no showing that there is anything critical about the 30:10
`
`IR/DR ratio; nor can it, because claim 3 of the '740 patent recites a much broader
`
`ratio of IR to DR "from 99:1 to 70:30" to achieve the same steady-state levels
`
`between 0.1 μg/ml and 1.0 μg/ml. Ex. 1001, claim 3. And the '740 patent also
`
`states these blood levels "can be accomplished with a single daily dose of an
`
`immediate release formulation." Id., col. 3:62-65; Ex. 1066, ¶¶72-76.
`
`F. Objective Indicia Do Not Support Patentability
`
`
`
`Supernus' objective indicia arguments lack merit and fail to support a
`
`conclusion of nonobviousness. Ex. 1066, Section X; Ex. 1056; Ex. 1071.
`
`There was no long-felt need. A showing of a long felt need requires that the
`
`need must have been a persistent one that was recognized by a POSA. In re
`
`Gershon, 372 F.2d 535, 539 (CCPA 1967). Supernus argues that a long-felt need
`
`- 8 -
`
`
`
`
`
`existed for a once-daily oral formulation of doxycycline to treat rosacea, without
`
`the undesired antibiotic side effects. Paper 39 at 45. But absent from the record is
`
`evidence "of an articulated identified problem and evidence of efforts to solve that
`
`problem." Texas Instr. Inc. v. U.S. Intern. Trade Com'n, 988 F.2d 1165, 1178 (Fed.
`
`Cir. 1993) (emphasis added). There is also no evidence of a persistent need
`
`recognized by a POSA. Gershon, 372 F.2d at 539.
`
`Supernus offers only the unsupported testimony of a dermatologist, Dr. Guy
`
`Webster, who admitted that he knew of no literature discussing a long-felt need for
`
`the claimed invention. Ex. 1054 at 113:2-11. An expert's bare assertion is not
`
`probative of a long-felt need. Perfect Web Tech., Inc. v. InfoUSA, Inc., 587 F.3d
`
`1324, 1333 (Fed. Cir. 2009). Dr. Webster alleged a "need" for a once-daily version
`
`of Periostat®, due to alleged patient compliance problems with twice-daily dosing.
`
`Ex. 2018, ¶26. But the record contains no documented evidence of such alleged
`
`problems or even a reliable head-to-head comparison of compliance rates. Ex.
`
`1054, 84:25-85:17.
`
`Dr. Elaine Gilmore, a practicing dermatologist who filed a declaration in
`
`support of Amneal's reply, explains that from a clinical perspective there is no
`
`evidence of a long-felt need for a once-daily oral rosacea treatment that avoided
`
`side effects associated with higher antibiotic doses. Ex. 1056, ¶¶25-30. Dr.
`
`Gilmore further explains that, contrary to Dr. Webster's assertions, there is no
`
`- 9 -
`
`
`
`
`
`reliable evidence that the claimed invention's side-effect profile is an improvement
`
`over 50 mg or 100 mg of doxycycline administered once-daily. Id., ¶¶ 27-29. She
`
`also explains that there is no evidence that twice-daily dosing created compliance
`
`concerns with patients, or that once-daily dosing achieves a better therapeutic
`
`outcome in rosacea patients. Id., ¶¶ 44-51. Dr. Webster further admitted that his
`
`opinions are unsupported by any controlled studies. Ex. 1054, 55:17-23, 76:11-21.
`
`There is no evidence of "failure of others." Supernus argues that a single
`
`biostudy of the "Faulding formulations" demonstrates a "failure of others." But that
`
`study showed at least one formulation could achieve steady-state blood levels
`
`within the range claimed by the '740 patent using once-daily dosing. Ex. 1066,
`
`¶78-80. And Supernus' arguments regarding Faulding's bioavailability levels are
`
`irrelevant because the '740 patent claims do not require any particular level of
`
`bioavailability. Ex. 1001, claims; Ex. 1066, ¶80. Moreover, the fact that
`
`Galderma/CollaGenex apparently elected not to pursue the Faulding formulation is
`
`of little probative value where there is no direct evidence of why
`
`Galderma/CollaGenex made that decision. See DyStar v. C.H. Patrick Co.,464
`
`F.3d 1356, 1371-72 (Fed. Cir. 2006).
`
`There is no commercial success. Supernus and its declarant, Dr.
`
`Grabowski, have shown only that a commercial embodiment of the claimed
`
`invention might enjoy healthy sales. But Supernus has not shown a nexus between
`
`- 10 -
`
`
`
`
`
`the allegedly novel elements of the challenged claims and any marketplace
`
`performance. See Ormco Corp. v. Align Tech., Inc., 463 F.3d 1299, 1312 (Fed. Cir.
`
`2006). Instead, the record confirms that Oracea® sales are driven by commercial
`
`factors as explained by Mr. Philip Green, an expert on economic issues involving
`
`intellectual property. Ex. 1071, ¶¶ 54-75.
`
`Mr. Green explains that the only arguably distinguishing features of
`
`Oracea®, the commercial embodiment of the claimed invention, that are
`
`potentially probative of commercial success are its once-daily dosing regimen and
`
`its 30:10 (IR/DR ) ratio. Id., ¶¶ 28-31, 36-40. But there is no evidence that these
`
`claimed features drive sales. Id., ¶41-49. In fact, Dr. Grabowski repeatedly insisted
`
`that all of Oracea®'s features drive sales. Ex. 1055 at 86:8-14, 87:10-88:2, 93:8-18,
`
`93:19-94:8. And Dr. Grabowski repeatedly emphasized Oracea®'s status as the
`
`only FDA-approved oral treatment for rosacea. Ex. 1071, ¶¶ 50-53. But any
`
`success due to such an "unclaimed feature" is irrelevant. Ormco Corp., 463 F.3d at
`
`1312. Moreover, it is well-settled that "if the feature that creates the commercial
`
`success was known in the prior art, the success is not pertinent." Id.; see also Tokai
`
`Corp v. Easton Enter., Inc., 632 F.3d 1358, 1369-70 (Fed. Cir. 2011). Dr.
`
`Grabowski did not consider the prior art. Ex. 1071, ¶¶ 32, 39-40, 47. As Dr.
`
`Grabowski did not properly analyze commercial success in this case, his opinions
`
`should be disregarded.
`
`- 11 -
`
`
`
`
`
`Supernus fails to establish copying. Supernus asserts that copying supports
`
`the nonobviousness of the '740 patent claims (see Paper 39 at 49), but "copying
`
`requires evidence of efforts to replicate a specific product." Wyers, 616 F.3d at
`
`1246. Supernus only relies on Dr. Rudnic's observation that various generic
`
`companies filed ANDAs seeking to market bioequivalent versions of Oracea. Upon
`
`cross-examination, Dr. Rudnic admitted that he relied only an excerpt from one
`
`page of the Amneal Paragraph IV Notice Letter (Ex. 2053) to speculate that
`
`Amneal's product meets all the limitations of all the '740 patent claims. Apart from
`
`Amneal's recitation of the word "bioequivalent," Dr. Rudnic could point to no
`
`other evidence of alleged "copying." Ex. 1052 at 326:11-14. Thus, there is no
`
`factual evidence of copying. Moreover, as the Federal Circuit has repeatedly held,
`
`"evidence of copying in the ANDA context is not probative of nonobviousness
`
`because a showing of bioequivalence is required for FDA approval." Bayer
`
`Healthcare Pharm., Inc. v. Watson Pharm., Inc., 713 F.3d 1369, 1377.
`
`II.
`
`SUPERNUS' ATTEMPTS TO SIDESTEP THE PRIOR ART FAIL
`
`A. Ashley '932 Properly Incorporated the '854 Application
`
`Ashley '932 identifies the '854 application with sufficient particularity, as
`
`viewed from the vantage point of a POSA, to incorporate it by reference in its
`
`entirety. Ex. 1002, 15:26-30; Ex. 1049, ¶¶22, 28-31; Ex. 1066, ¶¶13,107-08.
`
`Supernus' contrary arguments must fail, as Supernus' declarant Stephen Kunin
`
`- 12 -
`
`
`
`
`
`admittedly cannot offer the views of a POSA or speak to this question of law. Ex.
`
`1051 at 31:12-32:3; Hollmer v. Harari, 681 F.3d 1351 (Fed. Cir. 2012); See
`
`Advanced Display Sys., Inc. v. Kent State Univ., 212 F. 3d 1272, 1283 (Fed. Cir.
`
`2000) (holding that "[w]hether and to what extent material has been incorporated
`
`by reference into a host document is a question of law" to be determined using "the
`
`standard of one reasonably skilled in the art.") And a simple keyword search using
`
`the application's title unambiguously leads to a single application having the
`
`referenced April 5, 2001 filing date, as explained by Amneal's declarant Mr. John
`
`Doll. Ex. 1049, ¶¶29-40; Ex. 1066, ¶¶107-108. Thus, Ashley '854 is deemed as
`
`matter of law part of the Ashley '932 disclosure published on October 17, 2002. Id.
`
`Supernus attempts to distract from this straightforward legal question by
`
`offering irrelevant speculation as to how quickly a member of the public could
`
`have actually obtained a copy of Ashley '854. Paper 39 at 55-56. But the prior art
`
`date of a reference cannot turn on the speed at which the PTO's administrative
`
`machinery might move. Ex. 1049, ¶¶42-48. And, in any event, an interested POSA
`
`could have actually obtained a copy of the '854 application long before the April 7,
`
`2003 asserted priority date of the '740 patent. Id., ¶¶ 49-57.
`
`
`
`B.
`
`Supernus Fails to Antedate the Ashley References
`
`Even if the Board accepted all of Supernus' statements in its attempt to
`
`antedate Ashley '932, their argument still fails. First, Supernus does not assert that
`
`- 13 -
`
`
`
`
`
`the inventors made an embodiment of the claimed invention and demonstrated that
`
`it works for its intended purpose, as required for an actual reduction to practice.
`
`Instead, Supernus argues that "the inventors of the Chang '740 patent expressly
`
`contemplated conducting 'in silico modeling . . . .'" Paper 39 at 58. But
`
`contemplating in silico modeling is not an ARTP of the claimed invention. Ex.
`
`1066, ¶102. Second, Supernus failed to offer any inventor testimony or explain
`
`why such evidence is not provided. Borror v. Herz, 666 F.2d 569, 573 (CCPA
`
`1981). Third, the sole proffered witness on this issue, Dr. Jones Bryan, is a non-
`
`inventor who lacks personal knowledge of an ARTP and relies on hearsay in
`
`documents he did not prepare. Ex. 1053 at 62:9-25. Fourth, Dr. Bryan admitted
`
`that the in vivo study he relied on did not use an IR/DR formulation nor disclose
`
`steady-state blood level values for any formulation. Id. at 124:19-24; 126:1-7. So,
`
`Supernus cannot show that it had an ARTP of the claimed invention, and it cannot
`
`even show that it invented as much as Ashley '932 teaches, as Ashley '932 teaches
`
`steady state blood levels and IR/DR formulations. Ex. 1002, 11:1-3; Ex. 1003 at
`
`5:24-26.
`
`Moreover, Supernus offers no credible evidence of conception and diligence,
`
`as Dr. Bryan had no personal knowledge of the facts and events. And he did not
`
`explain the many substantial gaps in activity during the critical period. Ex. 1053 at
`
`62:9-64:20 & 72:24-73:5; see e.g. Ex. 2147 at 2, ll. 70-71 (more than a month of
`
`- 14 -
`
`
`
`
`
`inactivity); see Bosies v. Benedict, 27 F.3d 539, 542 (Fed. Cir. 1994); In re
`
`McIntosh, 230 F.2d 615, 619 (CCPA 1956). Supernus has not met its burden of
`
`persuasion that the Ashley references are antedated.
`
`C.
`
`Supernus' Attempt to Invoke the CREATE Act Must Also Fail
`
` Even if Supernus properly substantiated its CREATE Act claim, Supernus'
`
`attempt to invoke the CREATE Act here should be rejected. Under 35 U.S.C.
`
`§255, Supernus' Certificate of Correction cannot be used to amend the
`
`specification, because such an amendment would raise issues that necessitate
`
`further re-examination. For example, if the CREATE Act is used to disqualify
`
`subject matter as prior art, the '740 patent should be assessed for obviousness-type
`
`double patenting over patents arising from Ashley '932, e.g., USPNs 7,211,267;
`
`7,232,572; and 8,603,506. Supernus' CREATE Act claim must fail.
`
`III. CONCLUSION
`
`
`Nothing Supernus argued should alter the Board's initial views regarding
`
`unpatentability. Amneal has demonstrated by at least a preponderance of the
`
`evidence that claims 1, 2, 5-15, and 19-22 would have been obvious.
