`U.S. Patent No. 11,253,572 – 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 1-30 (the “Challenged Claims”) of U.S. Patent No. 11,253,572
`
`(“’572 patent”) (Ex.1001), assigned to Patent Owner, Regeneron Pharmaceuticals,
`
`Inc.
`
`The Challenged Claims are directed to treating angiogenic eye disorders,
`
`including diabetic macular edema (“DME”) and age-related macular degeneration
`
`(“AMD”), 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—claims 15-25—is directed to a dosing
`
`regimen for DME with two or more monthly loading doses followed by maintenance
`
`doses administered every two months (the “DME Claims”). Those claims were not
`
`challenged in Apotex’s prior ’572 IPR Petition (IPR2002-01524 (“Apotex
`
`Petition”)), which addressed the non-DME claims of the ’572 patent. Ex.1008.
`
`Unlike the other ’572 claims previously addressed by the Patent Trial and
`
`Appeal Board (“Board”), independent claim 15 and dependent claim 24 recite only
`
`DME dosing regimens and nothing more. They do not contain what the Board
`
`previously referred to as a “results limitation”—i.e. maintaining or gaining visual
`
`acuity. Ex.1004, 15. Instead, claim 15 recites treating DME by administering a
`
`1
`
`Biocon Exhibit 1070 Page 14
`
`

`

`U.S. Patent No. 11,253,572 – Petition for Inter Partes Review
`
`single initial dose of aflibercept, followed by “one or more” monthly secondary
`
`doses (the “loading” phase), and then maintenance doses every two months. Claim
`
`24 depends from claim 15 and recites that “only two secondary doses” are
`
`administered, meaning only three monthly doses are given before 8-week dosing.
`
`Thus, claims 15 and 24 are anticipated by any aflibercept DME prior art
`
`disclosing three monthly loading doses followed by 8-week maintenance dosing. A
`
`Regeneron press release from September 14, 2009 (“2009 Press Release”) discloses
`
`exactly that. It describes administering 2 mg aflibercept to treat DME using a dosing
`
`regimen of three monthly loading doses that include an initial and two “secondary”
`
`doses, followed by maintenance doses at 8-week intervals. Ex.1005. Another press
`
`release from December 20, 2010 (“December 2010 Press Release”) discloses the
`
`same DME regimen. Ex.1006. Thus, as shown in Ground I, each of the 2009 Press
`
`Release and December 2010 Press Release anticipates claims 15 and 24.
`
`A second subset of Challenged Claims—1-5, 8-11, 16-17, 20-21, and 26-30—
`
`recite a loading/maintenance regimen for generic angiogenic eye disorders, DME,
`
`or AMD, and also include certain “results limitations” reciting either a general result
`
`within a specific time frame (e.g., “wherein the patient achieves a gain in visual
`
`acuity within 52 [or 24] weeks”) or a specific visual acuity gain (e.g., “wherein the
`
`patient gains at least 7 [or 8 or 9] letters” in the standard ETDRS letter score for
`
`
`
`2
`
`Biocon Exhibit 1070 Page 15
`
`

`

`U.S. Patent No. 11,253,572 – Petition for Inter Partes Review
`
`visual acuity, or wherein the regimen is “as effective” as ranibizumab). These claims
`
`are collectively referred to as the “Results Claims” herein.
`
`Results Claims 1-5, 8-11, 16-17, and 20-21 recite treating either a generic
`
`angiogenic eye disorder or DME specifically (the “Generic Results Claims”/“DME
`
`Results Claims”). As shown in Ground II, the December 2010 Press Release
`
`anticipates the Generic/DME Results Claims. The December 2010 Press Release
`
`discloses the same dosing regimens for DME as the 2009 Press Release, but further
`
`reports the visual acuity results from DME clinical trials in which these regimens
`
`were applied. The December 2010 Press Release explicitly discloses that DME
`
`patients both achieved the results recited within the recited 24 or 52 week time
`
`frames, and that they achieved the specific visual acuity gains recited (e.g., a gain of
`
`at least 7, 8, or 9 letters).
`
`Similarly, Results Claims 26-30 recite a method for treating AMD via a
`
`loading/maintenance regimen (the “AMD Results Claims”), and further recite that
`
`the method is “as effective” as monthly ranibizumab at week 52. As shown in
`
`Ground III, the AMD Results Claims are anticipated by a November 22, 2010 Press
`
`Release (“November 2010 Press Release”), which discloses the same dosing
`
`regimen as the other press releases, but for treatment of AMD. Ex.1007. That Press
`
`Release further explicitly discloses the ranibizumab comparison results recited by
`
`the claim. Id.

`
`The Results Claims are also rendered obvious by the 2009 Press Release or
`
`separately by Dixon’s disclosure of the claimed dosing regimen for AMD. Notably,
`
`in the Apotex Petition, Apotex argued that the “results limitations” only were
`
`inherent or not entitl
