`DECISION
`Denying Petitioner’s Request for Rehearing
`37 C.F.R. § 42.71
`
`I.
`INTRODUCTION
`Micron Technology, Inc. (“Petitioner”) filed a Request for Rehearing
`(Paper 9, “Req. Reh’g”) of the Decision Denying Institution of Inter Partes
`Review of U.S. Patent No. 5,894,441 (Ex. 1001, “the ’441 patent”) (Paper 8,
`“Dec.”). Petitioner requests reconsideration of the denial of institution and
`contends that we misapprehended and overlooked teachings of McAdams
`
`
`
`IPR2016-00094
`Patent 5,894,441
`
`and Minami, as well as the specific rationale for combining these teachings.
`Req. Reh’g 1.
`
`II.
`STANDARD OF REVIEW
`Under 37 C.F.R. § 42.71(c), “[w]hen rehearing a decision on petition,
`a panel will review the decision for an abuse of discretion.” An abuse of
`discretion occurs when a “decision was based on an erroneous conclusion of
`law or clearly erroneous factual findings, or . . . a clear error of judgment.”
`PPG Indus., Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1567
`(Fed. Cir. 1988) (citations omitted). The request must identify, specifically,
`all matters the party believes the Board misapprehended or overlooked, and
`the place where each matter was addressed previously in a motion,
`opposition, or reply. 37 C.F.R. § 42.71(d).
`
`III. DISCUSSION
`In our Decision Denying Institution, we determined that Petitioner had
`not shown sufficiently that the combination of McAdams and Minami
`teaches “a column redundancy decoder activating said redundant column
`selection line in response to said first column address when said second
`word line is activated” (“the column redundancy decoder limitation”), as
`recited in claim 6. Dec. 13. We further determined that Petitioner did not
`provide sufficiently an articulated reasoning with some rational
`underpinning to support the legal conclusion of obviousness. Id. at 16.
`In its Request for Rehearing, Petitioner contends that we overlooked
`or misapprehended “the complete teachings of and contentions regarding
`McAdams” and “instead incorrectly relied on passages from McAdams
`‘alone’ and ‘by itself.’” Req. Reh’g 1. The Petition presented certain
`
`
`
`2
`
`
`
`IPR2016-00094
`Patent 5,894,441
`
`contentions regarding what McAdams discloses. Pet. 42–44. In our
`Decision Denying Institution, we explained why we were not persuaded by
`those contentions. Dec. 9–11. Petitioner acknowledged deficiency in the
`disclosure of McAdams, contending “[w]hat McAdams does not explicitly
`disclose is whether activating the column redundancy decoder occurs when a
`word line is activated.” Pet. 44. With respect to the column redundancy
`decoder limitation, however, the Petition did not provide a specific proposed
`modification of the teachings of McAdams alone or in combination with
`Minami. Instead, the Petition purported to remedy this deficiency by
`referencing back to a different claim limitation. Id. In the Decision, we
`explained why the contentions referencing back to the other limitation are
`deficient. Dec. 11.
`In addition, in its Request for Rehearing, Petitioner purports to
`identify specific contentions that we misapprehended and overlooked. Req.
`Reh’g at 4–14. For example, Petitioner contends:
`[T]he Board overlooked passages in the Petition that explain how
`McAdams’ redundant decoder is programmable with any
`address, including the first column address and second word line
`address. Immediately preceding this contention, the Petition
`describes how the programmed “column and row address” of
`McAdams would have been understood in this context:
`“Specifically, [clause 1] while the first column address and first
`word line activates the normal selection line, [clause 2] the same
`first column address and second word line activates the
`redundant column selection line.” Pet. 42.
`Req. Reh’g 7.
`Below is the description in the Petition that Petitioner asserts was
`overlooked.
`
`10.2.7. [6.6] “a column redundancy decoder
`activating
`said
`redundant
`column
`
`
`
`3
`
`
`
`IPR2016-00094
`Patent 5,894,441
`
`
`selection line in response to said first
`column address when said second word
`line is activated.”
`
`
`This limitation simply covers the concept of using a
`redundant bit line to replace only part of a column (a segment).
`Specifically, while the first column address and first word line
`activates the normal selection line, the same first column address
`and second word line activates the redundant column selection
`line. MICRON-1003, Baker Decl., Appx. A at claim [6.6].
`Pet. 42. Contrary to Petitioner’s assertion, the immediately preceding
`description in the Petition pertains to the challenged claim, not McAdams.
`Furthermore, Petitioner’s Request for Rehearing does not identify specific
`contentions in the Petition pertaining to how McAdams’ redundant decoder
`is programmable with any address that we overlooked or misapprehended.
`Upon review of the Request for Rehearing, we are not persuaded by
`Petitioner that we misapprehended or overlooked contentions in the Petition
`that were provided with sufficient specificity with respect to the column
`redundancy decoder limitation. In our Decision Denying Institution, we
`explained that a deficiency with the Petition and supporting Declaration is
`excessive referencing back to contentions regarding other claim limitations
`without specifying sufficiently which of the other contentions relate to the
`column redundancy decoder limitation and how they relate. Dec. 11–13.
`We cannot have overlooked or misapprehended contentions that were not
`specified sufficiently in the Petition as relating to the column redundancy
`decoder limitation.
`Petitioner contends that we did not consider the rationale for
`combining McAdams and Minami for claim 6 provided in the Petition. Req.
`Reh’g 13. We considered Petitioner’s contentions regarding reasons to
`
`
`
`4
`
`
`
`IPR2016-00094
`Patent 5,894,441
`
`combine presented prior to the element-by-element analysis (Pet. 26–29),
`and other contentions relating to claim 6 (id. at 32–44), to the extent that the
`contentions were provided with sufficient specificity. Dec. 13–16.
`For the foregoing reasons, we determine that our Decision Denying
`Institution was not “based on an erroneous conclusion of law or clearly
`erroneous factual findings, or . . . a clear error of judgment.” PPG Indus.,
`Inc., 840 F.2d at 1567 (citations omitted).
`
`IV. ORDER
`For the foregoing reasons, it is:
`ORDERED that Petitioner’s Request for Rehearing (Paper 9) is
`denied.
