`Second Declaration of Glenn A. Van Bnskirk, Ph.D. (Exhibit 1066)
`
`I.
`
`Overview
`
`1.
`
`I am over the age of eighteen (18) and otherwise competent to make
`
`this declaration.
`
`2.
`
`I have been retained as an expert witness on behalf of AMNEAL
`
`PHARMACEUTICALS, L.L.C and AMNEAL PHARMACEUTICALS COMPANY PVT. LTD.
`
`(together “AMNEAL“) for the above—captioned inter partes review (IPR). 1 am being
`
`compensated for my time in connection with this IPR at my standard consulting
`
`rate, which is $400 per hour.
`
`I understand that the petition for inter partes review
`
`involves U.S. Patent No- 8,394,405 ("the '405 patent"), Exhibit 1007, which
`
`resulted from U.S. Application No. 12/926,932 ("the '932 application"), filed on
`
`December 17, 2010, naming Rong-Kun Chang, Arash Raoufinia, and Niraj Shah as
`
`inventors. The '405 patent issued on March 12, 2013, from the '932 application. I
`
`further understand that, according to the USPTO records,
`
`the '405 patent
`
`is
`
`currently assigned to Supemus Pharmaceuticals, Inc.
`
`I understand that the earliest
`
`possible priority date for the ‘405 patent is April 7, 2003.
`
`3.
`
`I provided a previous declaration in this proceeding (Exl022). My
`
`first declaration in this proceeding set forth my opinions on the disclosures in the
`
`prior art and the understanding of a person of ordinary skill in the alt reading the

`
`disclosures in the prior art- I maintain the same opinions today that were set forth
`
`in my first declaration. [Exl022; see also, Ex20l5, 268:l3-21.]l
`
`4.
`
`I am submitting this second declaration in reply to Supernus' Patent
`
`Owner Reply (Case IPR20l3-00368, Paper 39;
`
`IPR20l3-00371, Paper 40;
`
`IPR20l3—00372, Paper 38) and declarations of Supemus witnesses that were
`
`submitted with the Patent Owner Reply (Ex20l6 and Ex2146).
`
`5.
`
`I understand that certain documents associated with this inter partes
`
`review proceeding are considered confidential. I reviewed the Proposed Protective
`
`Order (Exhibit 2171) and signed the corresponding acknowledgement form.
`
`11.
`
`Summary of opinions
`
`6.
`
`I have been asked by Counsel for Amneal to consider and respond to
`
`declaration testimony of Supernus declarants submitted with the Patent Owner
`
`Reply (Case IPR20I3—00368, Paper 39;
`
`IPR20l3—0O37I, Paper 40;
`
`IPR20l3—
`
`00372, Paper 38). In particular, this declaration is submitted in response to the

`
`Sec0ndDeciarut1'r)n of Glenn A. Van Bnskirk, PILD. (Exhibit 1066)
`
`Declaration of Dr. Edward Rudnic, Ex20l6. I have also considered and responded
`
`to the Declaration of Dr. Jones Biyan (EXZI46).
`
`7.
`
`I disagree with Dr. Rudnic’s assertion that my opinions set forth in my
`
`first declaration, EXIO22, rely on hindsight analysis of the prior art. As I stated in
`
`my first declaration and reiterate in this second declaration, a person of ordinary
`
`skill in the art would have been motivated to combine the Ashley ‘932 publication,
`
`which incorporates by reference the ‘854 application, with the Sheth ‘748 patent
`
`because a viable once-daily formulation of a tetracycline drug with improved
`
`controlled release (as disclosed in the ‘748 patent)
`
`is a desirable feature for
`
`compositions of doxycycline for the treatment of rosacea (as disclosed in the
`
`Ashley ‘932 publication). Furthermore, a person of ordinary skill in the art reading
`
`the ‘932 publication and ‘748 patent would have immediately envisaged at least
`
`the common incremental range of IR/DR ratios from 50:50 to 80:20 because this
`
`range is disclosed in the art. See, e.g., E41022, 111] 171-179.
`
`8.
`
`I disagree with Dr. Rudnic’s analysis of the prior art. Dr. Rudnic
`
`considers each prior art reference individually, rather than considering the prior art
`
`as a whole. Even when considering a single prior art reference, Dr. Rudnic focuses
`
`his analysis on a single embodiment of the disclosure rather than the teachings of
`
`the reference as a whole. Furthermore, Dr. Rudnic’s analysis implies that a person
`
`Ex. 1114 is a redacted version of Ex. 1066

`
`Sec0ndDeciarut1'r)n of Glenn A. Van Bnskirk, PILD. (Exhibit 1066)
`
`of ordinary skill
`
`in the art would have required explication in every reference,
`
`ignoring a skilled a1tisan’s recourse to logic, judgment, and common sense.
`
`9.
`
`I disagree with Dr. Rudnic’s opinions that the Ashley ‘932 publication
`
`and ‘S54 application “teach away” from doxycycline formulations containing only
`
`an IR and DR portion. Dr. Rudnic provides no actual evidence that the Ashley’932
`
`publication and ‘S54 application criticize, discredit, or otherwise discourage
`
`developing a doxycycline formulation containing only IR and DR portions. Dr.
`
`Rudnic- also ignores disclosures in the Ashley ‘854 application that are contrary to
`
`his opinions. For example, the Ashley ‘854 application expressly states that the
`
`formulations can contain an “instantaneous-release agent, a sustained-release
`
`agent, a delayed—release agent, and combinations thereof." [Ex1003, 5124-26.] The
`
`Ashley ‘854 application also states that the amount of drug released from the
`
`formulations can Vary. [Exl003, 5:15-20.] Furthermore, Dr. Rudnic focuses his
`
`analysis on a single preferred embodiment disclosed in the Ashley ‘854
`
`application, rather than considering the prior art (which includes the Sheth ‘748
`
`patent) as a whole.
`
`10.
`
`I also disagree with Dr. Rudnic’s opinions that the Sheth ‘748 patent
`
`“teaches away’
`
`from doxycycline formulations due to differences between
`
`J
`
`minocycline and doxycycline. As above, Dr. Rudnic provides no actual evidence
`
`that
`
`the Sheth ‘748 patent criticizes, discredits, or otherwise discourages

`
`Second Declaration of Glenn A. Van Bnskirk, PILD. (Exhibit I066)
`
`developing a once—daily, controlled—release doxycycline formulation. Furthermore,
`
`Dr. Rudnic overstates the differences between minocycline and doxycycline. As
`
`the Patent Trial and Appeal Board stated, with which I agree, “the otherwise close
`
`relatedness of these two drugs in structure and fiinction makes information about
`
`formulation of one relevant to formulation of the other.” [Case IPR20l3—00368,
`
`Paper 3 at 12; IPR20l3—0037l, Paper 11 at 12; IPR2013—00372, Paper 8 at 13.]
`
`11.
`
`I also disagree with Dr. Rudnic’s opinions that the “blended polymer”
`
`formulations of the Sheth ‘748 patent are not IR/DR formulations. Dr. Rudnic
`
`imputes a “rapid release” limitation to the DR portion of the '405 patent that is not
`
`recited or required by the claims of the '405 patent. Discussed below,
`
`the
`
`secondary—loading portions of the formulations disclosed in the Sheth ‘748 patent
`
`are consistent with a POSA’s understanding of the term, “delayed release.”
`
`12.
`
`I disagree with Dr. Rudnic’s opinions that secondary considerations
`
`support the nonobviousness of the invention as claimed in the ‘405 patent. Dr.
`
`Rudnic fails to provide actual evidence of secondary considerations and sets forth
`
`unsubstantiated opinions- Dr. Rudnic also fails to consider the purported evidence
`
`in view of the claims.
`
`Instead, Dr. Rudnic imputes
`
`limitations
`
`such as
`
`bioavailability that are not recited or required by the claims of the '405 patent.
`
`13.
`
`I disagree with Supernus' argument that the '932 publication does not
`
`identify the Ashley '854 application with sufficient particularity. The '932

`
`publication identifies the '85-4 application by title, filing date, and assignee. A
`
`POSA would have understood that the title and filing date are identical to those of
`
`the '854 application. A POSA would have also understood that the ‘854 application
`
`is directed to controlled release tetracycline formulations — the same subject matter
`
`recited in the title of the application incorporated by reference in the '932
`
`publication.

`
`Person of ordin ary skill in the art
`
`15.
`
`I understand that a person of ordinary skill in the art ("POSA") is a
`
`hypothetical person who is presumed to be aware of all pertinent art, thinks along
`
`conventional wisdom in the art, and is a person of ordinary creativity. A POSA
`
`would have had education and experience in drug delivery and formulation as of
`
`2003. The education and experience levels may vary between persons of ordinary
`
`skill, with some persons holding a Bachelor's degree with many years of
`
`experience and others holding higher degrees but having less work experience. A
`
`POSA would have knowledge and skill
`
`relating to the use,
`
`function, and

`
`formulation of pharmaceutical excipients; knowledge and training regarding the
`
`equipment, processes and techniques used to analyze and test
`
`formulation
`
`materials; and an understanding of pharmacokinetic principles and how they relate
`
`to drug development. Such a person would have specific experience with modified
`
`release drug systems.
`
`16.
`
`A person of ordinary skill
`
`typically would work as part of a
`
`multidisciplinary team and draw upon not only his or her own skills, but also take
`
`advantage of c-ertain specialized skills of others in the team,
`
`to solve a given
`
`problem. For example, a clinician may be part of the team.
`
`17.
`
`I understand that when considering the prior art, a POSA can rely on
`
`disclosures in the prior art as well as recourse to logic, judgment, and common
`
`sense. I understand that a POSA does not necessarily require explicit explication in
`
`any reference to understand the teachings therein.
`
`VI. Disclosures in the '405 patent regarding "delayed release"
`
`18.
`
`According to Dr. Rudnic, the term "delayed release" (DR) as recited
`
`in the claims of the '405 patent should be construed to mean a DR portion that
`
`releases "substantially no drug in the stomach, and delays release of substantially
`
`all drug until a later point in the GI tract." [Ex20l6, 1] 176.]
`
`I disagree with Dr.
`
`Rudnic‘s construction of "delayed release" in the context of the ‘405 patent.

`
`Second Declaration of Glenn A. Von Bnskirk, Ph.D. (Exhibit I066)
`
`19.
`
`A POSA reading the '405 patent would understand that the term, DR,
`
`encompasses a broad range of formulations. For example, the '405 patent refers to
`
`"a composition having a substantially immediate release dose of doxycyc-line,
`
`followed by at least one additional dose at a predetermined time,
`
`in a unit
`
`dosage." [Exl007, 5:33-36 (emphasis added).] The '405 patent also states that the
`
`doxycycline from the DR portion "becomes available when the pH—sensitive layer
`
`dissolves at the greater pH of the small intestine; after a certain delayed time; or
`
`after the unit passes through the stomach." [Exl007, 7:58-61 (emphasis
`
`added).] The '-405 patent also states that one embodiment of the DR portion
`
`"contains layers of the doxycycline, separated by protective layers, and finally an
`
`enteric coating, resulting in a ‘repeat-action‘ dosage delivery." [Exl007, 7:63-66
`
`(emphasis added).] The '405 patent also states that the DR portion "can be coated
`
`granular, coated beadlet, coated tablet, or uncoated matrix tablet." [Ex 1 007, 5:38-
`
`40 (emphasis added).]
`
`20.
`
`In view of the variety of DR formulations described in the '405 patent,
`
`a POSA would have interpreted the term "delayed release" to mean release of a
`
`drug at a time "other than immediately following oral administration." [Ex2058,
`
`30.]
`
`VII.
`
`I disagree with Dr. Rudnic"s opinions regarding disclosures in the prior
`art

`
`Second Declaration of Glenn A. Van Buskirk, Ph.D. (Exhibit 1066)
`
`A.
`
`Dr. Rudnic does not consider the prior art as a whole
`
`21.
`
`As I state above in 1] 15, I understand that a POSA is a hypothetical
`
`person presumed to be aware of all pertinent ait. Accordingly, a POSA would have
`
`read a prior art reference such as the Ashley '932 publication not in a vacuum, but
`
`with a collective awareness of all the perrinem‘ am‘. Moreover, a POSA can rely on
`
`recourse to logic, judgment, and common sense; and does not necessarily require
`
`explication in any reference.
`
`22.
`
`I disagree with Dr- Rudnic's opinions regarding disclosures in the
`
`Ashley references and the Sheth '748 patent because Dr. Rudnic does not consider
`
`the prior art as a who{e. Dr. Rudnic mentions considering the Ashley ‘854
`
`application — i.e., a single reference — "as a whole"2 (Ex20l6, 1]
`
`1 16), yet fails to
`
`consider the prior art as a whole. For example, Dr. Rudnic states:
`
`2
`
`While Dr. Rudnic states that
`
`the Ashley '854 application must be
`
`considered "as a whole" (Ex20l6, 1] 116), I note that Dr. Rudnic's opinions on the
`
`teachings of the '854 application are narrowly based on a single embodiment of the
`
`'85-4
`
`application that discloses
`
`a doxycycline
`
`formulation comprising an
`
`instantaneous release agent, a delayed release agent, and a sustained release agent.
`
`[E1-(2016, 1] 109.]

`Chse1TH?20I3-00371
`
`Second Declaration of Glenn A. Van Bnskirk, 1311.”. (Exhibit I066)
`
`[N]othing in the Ashley '932 publication discloses that 40
`
`mg once—daily administration or obtaining such target
`
`senim levels can be achieved with any formulation
`
`containing solely IR and DR components, let alone a 40
`
`mg doxycycline formulation with IR/DR ratios of 70:30-
`
`80:20 (or 75:25) as claimed in the Chang '405 patent.
`
`[Ex20l6, 1[89 (emphasis in original).]
`
`23.
`
`Such statements show that Dr. Rudnic focuses only on limited
`
`language in the Ashley '932 publication and fails to consider the disclosures in the
`
`Ashley '85-4 application, which is incorporated by reference in the '932 publication,
`
`as well as the disclosures in the Sheth '748 patent.
`
`24.
`
`Similarly, Dr. Rudnic also Views the Sheth '748 patent in isolation:
`
`In sum, there is no teaching, suggestion or motivation to
`
`Lise the Sheth '748 patent
`
`to formulate a once-daily
`
`formulation of doxycycline, and does not provide a
`
`skilled artisan with a reasonable expectation of success in
`
`doing so.
`
`[EX20l6, 11181.]
`
`25.
`
`Again, Dr. Rudnic focuses only on disclosures in the ‘748 patent and
`
`excludes from his analysis a POSA's understanding of the teachings in the Ashley
`
`‘932 publication and the ‘S54 application, which is incorporated by reference-
`
`-15-

`
`Second Declaration of Glenn A. Van Bnskirk, Ph.D. (Exhibit I066)
`
`26.
`
`Thus, Dr. Rudnic's analysis of the disclosures in the prior art differs
`
`from my own. Furthermore, Dr. Rudnic's analysis of the disclosures in the Ashley
`
`references and the Sheth '748 patent ignores a POSA's recourse to logic, judgment,
`
`and common sense. Instead, Dr. Rudnic's analysis implies that a POSA would have
`
`needed explication in every reference to understand the teachings therein.
`
`Therefore, I disagree with Dr. Rudnic’s opinions on the disclosures and teachings
`
`in the prior art references.
`
`B.
`
`The Ashley references and Sheth '748 patent do not "teach away"
`from the claimed invention
`
`27.
`
`Dr. Rudnic states that the Ashley '932 publication and ‘S54 application
`
`"teach away" from formulations having only IR and DR components. [Ex2016, fifil
`
`100, 119.] Dr. Rudnic also states that the Sheth '748 patent "teaches away" from
`
`formulations having a DR portion. [Ex20l6, 1] 180.] I disagree with Dr. Rudnic that
`
`any of the aforementioned prior art references teaches away from the invention as
`
`claimed in the '4
