`
`
`
`
`1. My name is Dr. Thomas A. Albini. I have been retained by counsel for
`
`Mylan Pharmaceuticals Inc. (“Mylan” or “Petitioner”) to provide my opinion
`
`regarding U.S. Patent No. 9,254,338 (Ex.1001, the “’338 patent”), which I
`
`understand is assigned to Regeneron Pharmaceuticals, Inc. (“Regeneron”). I
`
`understand that Petitioner intends to petition for inter partes review of the ’338
`
`patent, and will request that the United States Patent and Trademark Office cancel
`
`certain claims of the ’338 patent as unpatentable. My opinions in this expert
`
`declaration support Petitioner’s request for inter partes review of the ’338 patent and
`
`the cancellation of claims 1, 3-11, 13-14, 16-24, and 26 (the “challenged claims”).
`
`I.
`
`QUALIFICATIONS AND BACKGROUND.
`
`A. Education and Experience.
`
`2.
`
` I received a Bachelor of Arts degree, Magna Cum Laude, from
`
`Princeton University in 1994. I obtained my M.D. from Johns Hopkins University
`
`School of Medicine in 1999. I completed an internal medicine internship at Jackson
`
`Memorial Hospital in Miami, Florida, and an ophthalmology residency at the
`
`Doheny Eye Institute of the University of Southern California.
`
`3.
`
`After my residency, I completed a uveitis and ocular pathology clinical
`
`and research fellowship at the Doheny Eye Institute followed by a vitreoretinal
`
`surgery fellowship at the Cullen Eye Institute of the Baylor College of Medicine.
`
`1
`
`
`
`
`
`4.
`
`I was an instructor in ocular inflammation, uveitis, and ophthalmic
`
`pathology at the Doheny Eye institute from 2003-2004. I joined the faculty at the
`
`Bascom Palmer Eye Institute of the University of Miami Miller School of Medicine
`
`as an Assistant Professor of Clinical Ophthalmology in 2006. I held the position of
`
`Associate Professor of Clinical Ophthalmology at the Bascom Palmer Eye Institute
`
`from 2012 to June 2018. Since July 2016, I have served as co-director of the
`
`vitreoretinal surgery fellowship. Since June 2018, I have been a Professor of Clinical
`
`Ophthalmology. In my current and prior positions, I have been involved in the
`
`teaching and training of medical students, fellows, and residents in the area of
`
`ophthalmological surgical techniques, specifically, injection protocols for the
`
`administration of therapeutics for the treatment of age-related macular degeneration
`
`(AMD) and other vitreoretinal eye disorders. Further, in 2006, I began my current
`
`roles as a staff ophthalmologist at both the Anne Bates Leach Eye Hospital of the
`
`Bascom Palmer Eye Institute as well as the Jackson Memorial Hospital.
`
`5.
`
`I was awarded the American Academy of Ophthalmology Achievement
`
`Award in 2011 and Senior Achievement Award in 2019. In 2012, I received the
`
`Service Award from the American Society of Retina Specialists for outstanding
`
`service to the Society’s scientific and educational programs. I also received the
`
`Senior Honor Award from the American Society of Retina Specialists in 2012.
`
`2
`
`
`
`
`
`6.
`
`I have served as an editor, co-editor, or on the editorial board of several
`
`publications, including Retina Today, the website for the American Society of
`
`Retina Specialists, New Retina MD, and the Journal of VitreoRetinal Diseases.
`
`7. My clinical practice is focused on the diagnosis and treatment of
`
`patients suffering from various macular diseases, such as macular degeneration,
`
`diabetic retinopathy and related disorders, as well as uveitis. I have experience with
`
`surgical interventions as well as the prescription and administration of various
`
`intravitreally-administered anti-angiogenesis agents.
`
`8.
`
`I was and currently am a member in several Professional and Academic
`
`Societies, including American Academy of Ophthalmology, Association for
`
`Research in Vision and Ophthalmology, American Society of Retina Specialists,
`
`Miami Ophthalmological Society, Vitrectomy Buckle Society, American Uveitis
`
`Society, The Macula Society, Pan American Association of Ophthalmology, and
`
`The Retina Society, among others.
`
`9.
`
`I have authored or co-authored over two hundred and fifty (250)
`
`publications, including book chapters, peer-reviewed scientific papers, abstracts,
`
`and other published works. Several of these publications pertain to AMD, retinal
`
`detachment, retinal and choroidal diseases, or diabetic macular edema (DME),
`
`among other disorders of the eye.
`
`3
`
`
`
`
`
`10.
`
`In all, I have over fifteen (15) years of hands-on clinical and research
`
`experience specializing in treating vitreoretinal disorders and the prescription, and
`
`intravitreal administration, of VEGF antagonists. I have included a copy of my
`
`curriculum vitae in support of my opinions. (Ex.1038, Albini CV).
`
`B.
`
`Bases for Opinions and Materials Considered.
`
`11.
`
`In addition to my education, knowledge of the relevant published art,
`
`training, and experience, in forming the opinions I provide in this declaration, I have
`
`also considered the exhibits cited herein.
`
`C.
`
`Scope of Work.
`
`12.
`
`I have been retained by Petitioner as an expert in this matter to provide
`
`my various opinions regarding the ’338 patent. I receive $500 per hour for my
`
`services. No part of my compensation is dependent upon my opinions given or the
`
`outcome of this case. I do not have any current or past affiliation with Regeneron,
`
`or any of the named inventors on the ’338 patent.
`
`II. LEGAL STANDARDS.
`
`13. For my opinions in this declaration, I understand that it requires
`
`applying various legal principles. As I am not an attorney, I have been informed
`
`about various legal principles that govern my analysis. I have used my
`
`understanding of those principles in forming my opinions. I summarize my
`
`understanding of those legal principles as follows:
`
`4
`
`
`
`
`
`14. Burden of Proof. I understand that Petitioner bears the burden of
`
`proving unpatentability in this proceeding by a preponderance of the evidence. I am
`
`informed that this preponderance of the evidence standard means that Petitioner
`
`must show that unpatentability is more probable than not.
`
`15. Claim Construction. I have also been told that when I review and
`
`consider the claims, the claim term(s) should be analyzed under their ordinary and
`
`customary meaning as understood from the perspective of one of ordinary skill in
`
`the art, taking into account the claim language itself, specification, and prosecution
`
`history pertaining to the patent, as well as relevant extrinsic evidence. I have applied
`
`this standard in formulating my opinions, and set forth my understanding of the
`
`scope of particular claim terms discussed below.
`
`16. Anticipation. I have been asked to consider the question of
`
`anticipation, namely, whether the claims cover something that is new, or novel. I
`
`am told that the concept of anticipation requires that each and every element of a
`
`challenged claim is present in or otherwise taught by a single reference. I also
`
`understand that an anticipatory reference does not need to explicitly describe each
`
`element because anticipation can occur when a claimed limitation is necessarily
`
`inherent or otherwise implicit in the relevant reference.
`
`17. Obviousness. I have been asked to consider the question of
`
`obviousness/non-obviousness. Again, I am told that this analysis must be from the
`
`5
`
`
`
`
`perspective of the person of ordinary skill in the art, and whether such person would
`
`consider any differences between the prior art and what is claimed to have been
`
`obvious. To make this assessment, I have been informed that the concept of patent
`
`obviousness involves four factual inquiries:
`
`•
`
`the scope and content of the prior art;
`
`•
`
`the differences between the claimed invention and the prior art;
`
`•
`
`the level of ordinary skill in the art; and
`
`• so-called secondary considerations of non-obviousness.
`
`18.
`
`I have further been instructed that one cannot use the challenged patent
`
`itself (here, the ’338 patent) as a guide from which to select prior art elements, or
`
`otherwise engage in hindsight. Rather, the better approach is to consider what the
`
`person of ordinary skill in the art knew, and what the art taught; suggested; or
`
`motivated the person of ordinary skill in the art to further pursue; and to differentiate
`
`between steps that were routinely done (such as in response to known problems,
`
`steps, or obstacles), and those which, for example, may have represented a different
`
`way of solving existing or known problems.
`
`19.
`
`I am also informed that when there is some recognized reason to solve
`
`a problem, and there are a finite number of identified, predictable, and known
`
`solutions, a person of ordinary skill in the art has good reason to pursue the known
`
`options within his or her technical grasp. If such an approach leads to the expected
`
`6
`
`
`
`
`success, it is likely not the product of innovation but of ordinary skill and common
`
`sense. In addition, when a patent simply arranges old elements with each performing
`
`its known function and yields no more than what one would expect from such an
`
`arrangement, the combination is obvious.
`
`20.
`
`I understand that before reaching any final conclusion on obviousness,
`
`the obviousness analysis requires consideration of objective indicia of non-
`
`obviousness, if offered. These must be considered to ensure that, for example, there
`
`were not some unanticipated problems, obstacles, or hurdles that may seem easy to
`
`overcome in hindsight, but which were not readily overcome prior to the relevant
`
`invention date of the patents/claims at issue here. I understand that these objective
`
`indicia are also known as “secondary considerations of non-obviousness,” and may
`
`include long-felt but unmet need and unexpected results, among others. I also
`
`understand, however, that any offered evidence of secondary considerations of non-
`
`obviousness must be comparable with the scope of the challenged claims. This
`
`means that for any offered evidence of secondary considerations of non-obviousness
`
`to be given substantial weight, I understand the proponent of that evidence must
`
`establish a “nexus” or a sufficient connection or tie between that evidence and the
`
`merits of the claimed invention, which I understand specifically incorporates any
`
`novel element(s) of the claimed invention. If the secondary considerations evidence
`
`offered actually results from something other than the merits of the claim, then I
`
`7
`
`
`
`
`understand that there is no nexus or tie to the claimed invention. I also understand
`
`it is the patentee that has the burden of proving that a nexus exists.
`
`21. With respect to long-felt need, I understand that the evidence must
`
`show that a particular problem existed for a long period of time. More specifically,
`
`I understand that for a “need” to be long-felt and unmet, (i) the need must be
`
`persistent and recognized by those of ordinary skill in the art; (ii) the need must not
`
`be satisfied by another before the alleged invention; and (iii) the claimed invention
`
`itself must satisfy the alleged need. I also understand that long-felt need is analyzed
`
`as of the date that the problem is identified. Furthermore, I understand that long-felt
`
`need should be based upon alleged inadequacies in the technical knowledge of those
`
`skilled in the art, not due to business-driven market forces.
`
`22.
`
`I further understand that, absent a showing of a long-felt, unmet need,
`
`the mere passage of time without the claimed invention is not evidence of non-
`
`obviousness.
`
`23. With respect to unexpected results, I understand that any results upon
`
`which a patentee wishes to rely as an indicator of non-obviousness must be based on
`
`a comparison of the purported inventions with the closest prior art.
`
`24. However, I understand that secondary considerations will not overcome
`
`a strong showing of obviousness.
`
`8
`
`
`
`
`
`25. Public Availability. I have also been asked to consider whether there
`
`is a reasonable likelihood that some of the references discussed herein would have
`
`been publicly accessible before the priority date of the ’338 patent. I have been
`
`informed that a reference is “publicly accessible” if the document has been
`
`disseminated or otherwise made available to the extent that persons interested and
`
`ordinarily skilled in the subject matter or art exercising reasonable diligence, can
`
`locate it.
`
`III. PERSON OF ORDINARY SKILL IN THE ART.
`
`26. As I mentioned above, I have been informed by counsel that my
`
`analysis is to be conducted from the perspective of a person of ordinary skill in the
`
`art at the time of the invention. I also understand that the person of ordinary skill in
`
`the art is assumed to know, understand, and be familiar with all of the relevant prior
`
`art, and that such person is not an automaton, but rather a person of ordinary
`
`creativity.
`
`27.
`
`I have also been informed by counsel that in defining a person of
`
`ordinary skill in the art, the following factors may be considered: (1) the educational
`
`level of the inventor; (2) the type of problems encountered in the art; (3) prior art
`
`solutions to those problems; (4) rapidity with which innovations are made; and (5)
`
`sophistication of the technology and educational level of active workers in the field.
`
`9
`
`
`
`
`
`28. After considering the above-mentioned factors, it is my opinion that a
`
`person of ordinary skill in the art would have: (1) knowledge regarding the diagnosis
`
`and treatment of angiogenic eye disorders, including the administration of therapies
`
`to treat said disorders; and (2) the ability to understand results and findings presented
`
`or published by others in the field, including the publications discussed herein.
`
`Typically, such a person would have an advanced degree, such as an M.D. or Ph.D.
`
`(or equivalent, or less education but considerable professional experience in the
`
`medical, biotechnological, or pharmaceutical field), with practical academic or
`
`medical experience in: (i) developing treatments for angiogenic eye disorders, such
`
`as AMD, including through the use of VEGF antagonists, or (ii) treating of same,
`
`including through the use of VEGF antagonists.
`
`IV. SUMMARY OF OPINIONS.
`
`29.
`
`It is my opinion that Dixon anticipates the challenged claims of the ’338
`
`patent through Dixon’s disclosure of the dosing regimen used by Regeneron in their
`
`Phase 3 VIEW1 and VIEW2 AMD trials (3 monthly doses of 2 mg, followed by 2
`
`mg every eight weeks).
`
`30.
`
`It is my opinion that Adis anticipates the challenged claims of the ’338
`
`patent through Adis’ disclosure of the dosing regimen used by Regeneron in their
`
`Phase 3 VIEW1 and VIEW2 AMD trials (3 monthly doses of 2 mg, followed by 2
`
`mg every eight weeks).
`
`10
`
`
`
`
`
`31.
`
`It is my opinion that Regeneron’s May 2008 Press Release (“Regeneron
`
`(8-May-2008)”) anticipates the challenged claims of the ’338 patent through the
`
`disclosure of the dosing regimen used by Regeneron in their Phase 3 VIEW2 AMD
`
`trial (3 monthly doses of 2 mg, followed by 2 mg every eight weeks).
`
`32.
`
`It is my opinion that Regeneron’s publicly accessible clinicaltrials.gov
`
`submissions (NCT-795 and NCT-377) also anticipate the challenged claims of the
`
`’338 patent through their disclosure of the dosing regimen used by Regeneron in
`
`their Phase 3 VIEW1 and VIEW2 AMD trials (3 monthly doses of 2 mg, followed
`
`by 2 mg every eight weeks).
`
`33.
`
`It is my opinion that the public disclosures of Regeneron’s
`
`VIEW1/VIEW2 trials make the challenged claims obvious, because they disclose all
`
`aspects of the claimed dosing regimen, and because combined with the skilled
`
`person’s knowledge regarding the VEGF Trap-Eye/aflibercept sequence and
`
`structure (as disclosed in the ’758 patent and Dix), as well as the motivation in the
`
`art to reduce injection frequency, and the positive results observed in the Phase 2
`
`CLEAR-IT clinical trials, persons of ordinary skill in the art would have had a
`
`reasonable expectation of success in using the VIEW1/VIEW2 regimens.
`
`34.
`
`It is also my opinion that there are no “secondary considerations” that
`
`would support the patentability of the claims of the ’338 patent. First, it is my
`
`understanding that secondary considerations are not relevant in the context of
`
`11
`
`
`
`
`anticipation and it is my opinion that each of the VIEW1/VIEW2 disclosures
`
`mentioned above anticipate the ’338 patent claims. Second, in the context of
`
`obviousness, it is my opinion that the arguments presented by Regeneron to the U.S.
`
`Patent and Trademark Office do not support a finding of surprising or unexpected
`
`results, especially given the positive and promising results reported for the Phase 2
`
`trial and public disclosure of the Phase 3 dosing regimen.
`
`V. THE ’338 PATENT (Ex.1001).
`
`35.
`
`I have read the ’338 patent, which is titled “Use of a VEGF Antagonist
`
`to Treat Angiogenic Eye Disorders,” as well as the issued claims. I am very familiar
`
`with the state of the art at the time this patent was first filed, which I have been asked
`
`to assume is January 13, 2011.1 The ’338 patent lists George D. Yancopoulos as the
`
`sole inventor.
`
`
`1 I understand the following from the cover page of the ’338 patent: (i) Application
`
`No. 13/940,370 (“the ’370 application”) issued as the ’338 patent on or about
`
`February 9, 2016; (ii) the ’370 application was filed July 12, 2013; (iii) as a
`
`“continuation-in-part” of application No. PCT/US2012/020855, which was filed on
`
`January 11, 2012; and (iv) the ’338 patent lists three “provisional” applications filed,
`
`respectively, on (a) January 13, 2011; (b) January 21, 2011; and (c) November 21,
`
`
`
`12
`
`
`
`36.
`
`Ihave reviewed the ’338 patent claims from the perspective of a person
`
`of ordinary skill in the art and applied each claim’s ordinary and customary meaning
`
`in light of the claims, the specification, and the prosecution history, as well as any
`
`relevant extrinsic evidence. I understandthat Petitioner is challenging claims1, 3-
`
`11, 13-14, 16-24, and 26.
`
`37.
`
`Claims| and 14 are the only independent claims and read as follows:
`
`1. A method for treating an angiogenic eye disorder in a
`patient, said method comprising sequentially administering
`to the patient a single initial dose of a VEGF antagonist,
`followed by one or more secondary doses of the VEGF 5
`antagonist, followed by one or more tertiary doses of the
`VEGFantagonist;
`wherein each secondary doseis administered 2 to 4 weeks
`after the immediately preceding dose; and
`wherein each tertiary dose is administered at least 8 weeks 1°
`after the immediately preceding dose;
`wherein the VEGF antagonist is a VEGF receptor-based
`chimeric molecule comprising (1) a VEGFR1 compo-
`nent comprising aminoacids 27 to 129 of SEQ ID NO:2;
`(2) a VEGFR2 component comprising amino acids 130-
`231 of SEQ ID NO:2; and (3) a multimerization com-
`ponent comprising amino acids 232-457of SEQ ID
`NO:2.

`
`
`
`2011, as “Related U.S. Application Data.” (See Ex.1001, ’338 patent at Cover).
`
`I
`
`have been asked to assume that the priority date of the ’338 patent is January 13,
`
`2011.
`
`I have formed no opinion regarding the merit of the °338 patent’s claim to
`
`that date.

`
`A.
`
`Claim Construction.
`
`40.
`
`In myopinion, a person of ordinary skill in the art would reachat least
`
`the following conclusions regarding the claim language:
`
`41.
`
`First, although the terms “initial dose,” “secondary dose,” and “tertiary
`
`dose”are not typically used in practice, a person of ordinary skill in the art would
`
`understand the terms to have the meaning expressly given to them in the ’338 patent
`
`specification:
`
`
`
`oe 8
`“secondary doses,” and “tertiary
`The terms “initial dose,”
`doses,” refer to the temporal sequenceofadministration ofthe
`VEGFantagonist. Thus,the “initial dose” is the dose whichis
`administered at the beginning of the treatment regimen(also
`referred to as the “baseline dose”); the “secondary doses” are 35
`the doses which are administered after the initial dose; and the
`
