`U.S. Patent No. 10,888,601– Petition for Inter Partes Review
`
`I.
`
`
`INTRODUCTION
`Samsung Bioepis Co., Ltd. (“Petitioner”) petitions for inter partes review
`
`(“IPR”) under 35 U.S.C. §§ 311-319 and 37 C.F.R. §§ 42 et seq., seeking
`
`cancellation of claims 10-33 and 46-47 (the “Challenged Claims”) of U.S. Patent No.
`
`10,888,601 (“’601 patent”) (Ex.1001), assigned to Patent Owner, Regeneron
`
`Pharmaceuticals, Inc.
`
`
`
`The Challenged Claims are directed to treating diabetic macular edema
`
`(“DME”), diabetic retinopathy (“DR”), or DR in a patient with DME by
`
`administering aflibercept via a number of initial monthly loading doses, followed by
`
`maintenance doses administered every two months. One subset of the Challenged
`
`Claims is directed to a dosing regimen with two or more monthly loading doses
`
`followed by maintenance doses administered every two months. The other subset
`
`of Challenged Claims specify a dosing schedule of five monthly loading doses
`
`followed by maintenance doses administered every two months.
`
`
`
`The concept of treating DR/DME by administering a number of monthly
`
`loading doses followed by less frequent maintenance doses was well-known in the
`
`prior art. See, e.g. Ex.1005, Heier 2011; Ex.1006, Elman 2010; Ex.1002, Chaum
`
`Declaration, ¶¶43-61. During the loading phase, an initial dose followed by
`
`sequential monthly doses were given. The purpose of the “initial intensive monthly
`
`loading dose phase” was to gain “control of neovascular leakage” by stopping the
`
`
`

`
`growth of new, leaky blood vessels that cause angiogenic eye disorders. Ex.1005,
`
`Heier 2011, 1099, 1104. Thus, for most patients, the bulk of improvement generally
`
`occurred during this phase. The purpose of the subsequent maintenance phase was
`
`to maintain the improved condition while administering fewer doses, thereby
`
`reducing “risks of cataract, intraocular inflammation, retinal detachment and
`
`endophthalmitis,” as well as the “significant time and financial burden” on patients.
`
`Ex.1008, Dixon, 1577; see generally Ex.1002, ¶¶58-61.
`
`
`
`For example, a Regeneron press release from September 14, 2009 (“2009
`
`Press Release”) explicitly teaches dividing the treatment period into a “loading”
`
`phase and “maintenance” phase. Ex.1009, 2009 Press Release. Specifically, the
`
`2009 Press Release describes administering 2 mg aflibercept to treat DR/DME using
`
`a number of different dosing regimens, including one consisting of three monthly
`
`loading doses followed by maintenance doses at 8-week intervals. Ex.1009.
`
`
`
`As shown in Ground I, the 2009 Press Release thus anticipates Challenged
`
`Claims 46 and 47, which recite the general use of loading and maintenance dosing
`
`to treat DR/DME, specifying at least two initial monthly loading doses followed by
`
`any number of maintenance doses at 8-week intervals. The 2002 Press Release
`
`explicitly teaches such a regimen to treat DR/DME.
`
`
`
`Additionally, as set out in Ground II, the 2009 Press Release alone or in
`
`combination with Shams renders obvious the Challenged Claims that require five
`
`
`

`
`specific loading doses, including independent claims 10, 18, and 26. There is no
`
`special benefit taught in the ’601 patent to using five loading doses as opposed to
`
`two, three, four, six, or more loading doses. The ’601 patent states that “[t]he
`
`methods of the invention may comprise administering to the patient any number of
`
`secondary and/or tertiary doses of a VEGF antagonist” including “e.g. 2, 3, 4, 5, 6,
`
`7, 8, or more.” Ex.1001, 4:13-22. The patent does not contain any data for the use
`
`of only five monthly loading doses for any indication, let alone DR/DME; instead,
`
`the only discussion of five doses is part of a list of twenty other loading/maintenance
`
`dosing regimens it discloses for DR/DME, none of which are supported by
`
`additional data. Id., 15:35-17:28.
`
`
`
`Five loading doses is simply the number that works for some patients, and,
`
`importantly, the claims do not require the dosing regimen to apply to all patient
`
`populations in a one-size-fits-all approach. Nor could they, as there is no data in the
`
`patent supporting such a conclusion. Thus, the claims are directed to a “method for
`
`treating diabetic macular edema in a patient in need thereof,” not an entire patient
`
`population or a percentage thereof, because that is all the specification describes.
`
`There is thus no requirement that a POSA would have been motivated to adopt five
`
`initial loading doses for all patients.
`
`
`
`As set out above, the 2009 Press Release describes using three monthly
`
`loading doses followed by 8-week maintenance doses, among other regimens.

`
`Ex.1009. The only difference between this disclosure and the dosing regimen of
`
`claims 10, 18, and 26 of the ’601 patent is the number of initial monthly doses.
`
`While three might be appropriate for some patients, a POSA would have understood
`
`that other patients would benefit from additional loading doses, including five
`
`monthly loading doses. Indeed, one of the other regimen
