`
`INTRODUCTION
`I have been retained by the law firm Quinn Emanuel Urquhart &
`
`Sullivan on behalf of Samsung Bioepis Co., Ltd., (hereinafter, “Petitioner”) to
`
`provide expert opinions concerning antagonists of Vascular Endothelial Growth
`
`Factor (“VEGF”) used as intravitreal injection for the treatment of angiogenic
`
`disorders such as age related macular degeneration, diabetic retinopathy, diabetic
`
`macular edema, central retinal vein occlusion (CRVO), branch retinal vein occlusion,
`
`and corneal neovascularization.
`
`Specifically, I have been asked to provide my opinions related to U.S.
`
`Patent No. 11,253,572 (“the ’572 patent”) (Ex. 1001) and the scientific and technical
`
`knowledge regarding the subject matter of the ’572 patent before and for a period
`
`following the earliest priority date of the application that led to the ’572 patent. For
`
`purposes of this expert declaration, I have been asked to assume that the earliest
`
`priority date of the ’572 patent is January 13, 2011 for all claims other than claim
`
`25.
`
`My opinions in this declaration are based on the documents I cite along
`
`with my professional training, experience and knowledge that I have acquired
`
`working in the field of ophthalmology over the past 30 years. I am being
`
`compensated for my services as an expert at my standard consulting rate of $1500
`
`1
`
`Samsung Bioepis Exhibit 1002
`Page 12
`
`
`
`per hour. My compensation is in no way contingent on the substance of my opinions
`
`or the outcome of this case.
`
`My opinions and their underlying reasoning are explained in detail
`
`below.
`
`II.
`
`BACKGROUND AND QUALIFICATIONS
`I am an ophthalmologist with over 30 years of experience in the
`

`
`INFORMATION RELIED UPON
`In addition to my general knowledge gained as a result of my education
`
`and experience as an ophthalmologist, I have reviewed and considered, among other
`
`things, the ’572 patent, the prosecution history of the ’572 patent, and the prior art
`
`of record discussed herein.
`
`I also considered the Final Written Decision (“FWD”) issued by the
`
`Patent Trial and Appeal Board (“Board”) in IPR2021-00881 (“the ’338 IPR”)
`
`5
`
`Samsung Bioepis Exhibit 1002
`Page 16
`
`
`
`concerning U.S. Patent No. 9,254,338 (“’338 Patent”), finding all challenged claims
`
`there unpatentable. See Ex. 1011, ’338 FWD. I understand the ’338 and ’572 patents
`
`are in the same patent family and share the same specification. I have formed an
`
`opinion regarding the ’572 claims here independent of the ’338 FWD, but I found
`
`the ’338 FWD to be, in my judgment, consistent with my independent opinion
`
`expressed herein.
`
`I further considered the Institution Decision in IPR2022-01226 (“’601
`
`IPR”). I understand the ’601 IPR was instituted on January 11, 2023. Ex. 1013, ’601
`
`ID. I have formed an opinion regarding the ’572 claims here independent of the ’601
`
`ID, but I found the ’601 ID to be, in my judgment, consistent with my independent
`
`opinion expressed herein.
`
`The full list of information, in addition to my professional, academic
`
`and clinical experience, that I have relied upon in forming my opinions for this report
`
`is set forth throughout the report and in the Table of Exhibits.
`
`Where my conclusions are based on certain assumptions that I have
`
`adopted, I have stated such assumptions in this Declaration.
`
`IV. RELEVANT LEGAL STANDARD
`In forming my opinions and considering the patentability of the claims
`
`of the ’572 patent, I am relying upon certain legal principles that counsel for
`
`Petitioner have explained to me, as listed below.
`
`6
`
`Samsung Bioepis Exhibit 1002
`Page 17
`
`
`
`I understand that for an invention claimed in a patent to be found
`
`patentable, it must be, among other things, new and not obvious in light of what
`
`came before it. Patents and publications which predated the invention are generally
`
`referred to as “prior art.”
`
`For patent invalidity under an inter partes review, I understand the
`
`burden is on the party asserting unpatentability to prove it by a preponderance of the
`
`evidence. I understand that “a preponderance of the evidence” is evidence sufficient
`
`to show that a fact is more likely than not.
`
`A.
`
`Person of Ordinary Skill in the Art
`I have been informed that the claims of a patent are judged from the
`
`perspective of a hypothetical construct involving “a person of ordinary skill in the
`
`art” (“POSA”). The “art” is the field of technology to which the patent is related. I
`
`understand that the purpose of using a POSA’s viewpoint is objectivity. Thus, I
`
`understand that the question of validity is viewed from the perspective of a POSA,
`
`and not from the perspective of (a) the inventor, (b) a layperson, or (c) a person of
`
`extraordinary skill in the art. I have been informed that the claims of the ’572 patent
`
`are interpreted as a POSA would have understood them at the relevant time period
`
`(i.e., when the patent application was filed or the earliest effective filing date).
`
`I have been informed that in the ’338 IPR, the petitioner proposed – and
`
`the Board adopted – the following definition for the relevant POSA:
`
`7
`
`Samsung Bioepis Exhibit 1002
`Page 18
`
`
`
`A person of ordinary skill in the art at the time of the
`invention would have had (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.
`Ex. 1011, ’338 FWD, 9-11.
`
`I understand that in the ’338 FWD, the Board found that petitioner’s
`
`definition was “reasonable and consistent with the ’338 Patent and the prior art or
`
`record.” Ex. 1011, ’338 FWD, 10.
`
`Based on my review of the patent and prior art, I agree with the Board’s
`
`definition of a POSA adopted in the ’338 FWD, and in my opinion it should be
`
`adopted here consistent with the relevant art before the earliest priority of the ’572
`
`patent.

`
`Claim Construction
`I understand the first step in determining whether a patent claim is valid
`
`is to properly construe the claims. I understand that each claim of a patent subject
`
`to inter partes review is to be interpreted in light of the language of the claim, the
`
`written description, the figures, and the prosecution history of the patent.
`
`I further understand that in the absence of a specific definition within
`
`the specification or the reliance on a specific meaning in the prosecution history, the
`
`terms as used in the challenged claims of the ’572 patent are to be afforded their
`
`plain and ordinary meaning at the time of the invention.
`
`I understand that the “plain and ordinary meaning” of a term means the
`
`ordinary and customary meaning given to the term by those of ordinary skill in the
`
`art at the time of the invention and that the ordinary and customary meaning of a
`
`term may be evidenced by a variety of sources, including the words of the claims,
`
`the specification, drawings, and prior art.
`
`I understand that in construing claims all words in a claim must be
`
`considered in judging the patentability of that claim against the prior art.
`
`I understand that extrinsic evidence may be consulted for the meaning
`
`of a claim term as long as it is not used to contradict claim meaning that is
`
`unambiguous in light of the
