`I.
`
`INTRODUCTION
`Pursuant to 35 U.S.C. §§ 311–319 and 37 C.F.R. § 42, Dr. Reddy’s
`
`Laboratories, Inc. (“Petitioner”) petitions for Inter Partes Review (“IPR”) of claims
`
`1–6, 11–12, 14–34 of U.S. Patent No. 7,189,740 (“the ’740 patent”) (Ex. 1001),
`
`currently assigned to Celgene Corporation (“Patent Owner”) and seeks a
`
`determination that these claims of the ’740 patent be cancelled as unpatentable.
`
`This Petition is filed in accordance with 37 C.F.R. § 42.106(a). Concurrently
`
`filed herewith is a Power of Attorney and exhibit list pursuant to 37 C.F.R.
`
`§ 42.10(b) and §42.63(e). Pursuant to 37 C.F.R. § 42.103, the fee set forth in
`
`§ 42.15(a) accompanies this Petition.
`
`This Petition demonstrates that a preponderance of the evidence shows a
`
`reasonable likelihood that ’740 patent claims 1–6, 11–12, and 14–34 are
`
`unpatentable over the prior art. Specifically, the ’740 patent claims the use of about
`
`5–50 mg/day of
`
`lenalidomide (trade names Revlimid/Revimid)
`
`to
`
`treat
`
`myelodysplastic syndromes (MDS).
`
`II. GROUNDS FOR STANDING
`Petitioner certifies that the ’740 patent is available for inter partes review and
`
`that the Petitioner is not barred or estopped from requesting inter partes review on
`
`the grounds identified herein.

`III.
`
`IDENTIFICATION OF CHALLENGE AND STATEMENT OF THE
`PRECISE RELIEF REQUESTED (37 C.F.R. §42.22(a) and 37 C.F.R.
`§42.104(b))
`Petitioner requests inter partes review and cancellation of claims 1–6, 11–12,
`
`14–34 of the ’740 patent on the grounds set forth below.
`
`
`
`Petitioner challenges claims 1–6, 11–12, 14–34 of the ’740 patent as
`
`unpatentable as follows:
`
`Ground 1: Claims 1–6, 11–12, and 14–34 were unpatentable as obvious over
`
`List 2001 in view of the ’230 patent and Celgene Press Releases 5/8/2001 and
`
`8/28/2001.
`
`Ground 2: Claims 1–6, 11–12, and 14–34 were obvious over Thomas 2000a
`
`in view of the ’230 patent and Celgene Press Releases 5/8/2001 and 8/28/2001.
`
`The ’740 patent is to be reviewed under pre-AIA § 103. Petitioner’s detailed
`
`statement of the reasons for the relief requested is set forth below. In support,
`
`Petitioner submits the expert declaration of Dr. Levin (Ex. 1003) and also relies on
`
`Exhibits set forth in the concurrently filed Listing of Exhibits, per 37 C.F.R.
`
`§ 42.6(c).
`
`IV. THRESHOLD REQUIREMENT FOR INTER PARTES REVIEW
`A petition for inter partes review must demonstrate “a reasonable likelihood
`
`that the petitioner would prevail with respect to at least 1 of the claims challenged
`
`in the petition.” 35 U.S.C. § 314(a). This Petition meets this threshold.

`

`V.
`
`STATEMENT OF REASONS FOR THE RELIEF REQUESTED
`A.
`Summary of the Argument
`Prior to the priority date, a skilled artisan was aware of at least the following:
`
`lenalidomide and its position as the “next generation,” more potent thalidomide
`
`analog; lenalidomide’s and thalidomide’s successful clinical administrations in
`
`myelodysplastic syndromes (MDS) as well as other cancers including multiple
`
`myeloma (MM); and lenalidomide’s repeated, successful clinical administrations at
`
`5–50 mg/day.
`
`Lenalidomide was known, as was its clinical use. Both lenalidomide and its
`
`structural analog and precursor, thalidomide, acted on similar therapeutic targets
`
`(notably, a protein involved in cell signaling called tumor necrosis factor alpha, or
`
`TNFα), a target that is shared among multiple cancers (including MDS and multiple
`
`myeloma (MM)). However, lenalidomide’s anti-TNFα potency over thalidomide—
`
`its position to be the “next generation” for thalidomide—was well-established in the
`
`art. A skilled artisan was aware that lenalidomide’s successes had motivated
`
`searches for additional therapeutic applications.
`
`The most obvious places to begin were conditions for which thalidomide had
`
`already shown positive results. Thalidomide had shown promise in multiple cancers,
`
`including MDS, MM, and solid tumors. But thalidomide suffered from recognized
`
`drawbacks, including its toxicity profile and known teratogenicity. Lenalidomide,
`
`3
`
`

`

`with increased potency, decreased toxicity/side effects, and action on the same
`
`therapeutic target, helped remedy thalidomide’s known drawbacks.
`
`Clinical trials of lenalidomide in MM showed that doses of 5–50 mg/day were
`
`safe, well-tolerated, and showed efficacy (including by reduction in a validated
`
`clinical marker). A study of lenalidomide in solid tumors likewise showed the safety
`
`and toleration of 5–50 mg/day and sufficient promise to expand for a clinical trial.
`
`And additional clinical trials for MM—and for MDS—were underway.
`
`Whether a skilled artisan was searching for new anti-TNFα applications of the
`
`promising drug lenalidomide, or was searching for improved treatments for MDS
`
`patients over thalidomide and the other known therapies, lenalidomide was an
`
`obvious choice for administering to an MDS patient.
`
`By 2001, the skilled artisan would have understood lenalidomide to be the
`
`improved, “next generation” of thalidomide, that first thalidomide and then
`
`lenalidomide had already been used to clinically treat MDS, and that 5–50 mg/day
`
`of lenalidomide was a repeatedly recognized safe and well-tolerated dosage to use
`
`as a starting point for treating other cancers. The skilled artisan would apply this
`
`rationale to MDS with lenalidomide as claimed in the ’740 patent, with a reasonable
`
`expectation of success. Simply put, there were no scientific hurdles to clear and the
`
`claims of the ’740 patent were obvious.

`B.
`
`The ’740 Patent and Its Prosecution
`1.
`The ’740 Patent
`
`The ’740 patent was filed on April 11, 2003, claiming priority to provisional
`
`application No. 60/418,468 filed October 15, 2002. The ’740 patent names Jerome
`
`B. Zeldis as inventor and Celgene Corporation as assignee.
`
`The ’740 patent issued with 34 claims on March 13, 2007. Claim 1, the
`
`independent claim, relates to a method of treating MDS by administering about 5 to
`
`50 mg per day of lenalidomide (3-(4-amino-l-oxo-1,3-dihydro-isoindol-2-yl)-
`
`piperidine-2,6-dione) or
`
`) or a “pharmaceutically
`
`acceptable
