`Introduction
`On Ground 1, Samsung’s Reply only further exposes the fact that Samsung
`
`has failed to show a plurality of interconnections “formed to project from” a surface
`
`of the transistor array substrate.” In its first ground, Samsung relies solely on
`
`Kobayashi to satisfy this express claim requirement and all of 1[b], for that matter.
`
`But even a cursory glance at Kobayashi shows that Samsung’s theories must fail.
`
`That
`
`is because, whatever
`
`spatial
`
`relationships Kobayashi’s
`
`supposed
`
`interconnections have with the surface of the transistor array substrate, they
`
`demonstrably do not “project from” that surface. This claim requirement—"project
`
`from” has a meaning -Each word must means something. The element is not “formed
`
`to project upward, from a surface” or formed away from a surface” or “formed to
`
`project with respect to a surface” or something as broad as (d) above…”. Instead, it
`
`is formed “to project from a surface.”
`
`This is where Samsung’s problems become insurmountable, because its
`
`theories rest on an interpretation that is several steps broader and more dissimilar to
`
`the actual claim requirement than either (a) – (c) above. As Samsung’s expert
`
`admitted during deposition, to make Kobayashi satisfy the claim requirements,
`
`Samsung misinterpreted the actually claimed phrase, formed to “project from a
`
`surface” to merely require that the interconnections are (d) formed anywhere
`
`“above” a surface:

`
`That is not the only fatal problem under Ground 1. Applying the parties’
`
`
`
`agreed construction, Samsung’s Reply makes at least Samsung’s failure to show the
`
`(i) “arrayed along” claim requirement abundantly clear. Samsung admits that 117
`
`is not coplanar with 118. Indeed, 117 and 118 do not share any overlapping layers
`
`in the formation of the entire package. Reply at 20
`
`Samsung’s Ground 2 fares no better. Childs does not satisfy the “Lower”
`
`electrodes (green) are not “on the surface” of the transistor array substrate (orange).
`
`(Id.) Instead, large portions of the pixel electrodes are buried under and in the
`
`alleged substrate. (Id.) One look at the patent specification proves this beyond
`
`reasonable debate. While Samsung expressly relies in Figure 2, the reference makes
`
`clear that the lower electrode 21 is not on any surface of the substrate. Just the
`
`opposite is true. Childs clearly explains that The “Figures 2 and 3 illustrate a LED
`
`construction in which the lower electrode 21 is formed as a thin film in the circuit
`
`substrate 100. Indeed, it then states that “the subsequently-deposited organic
`
`semiconductor material 22 contacts this thin-film electrode layer 21 at a window 12a
`
`in a planar insulating layer 12 (for example
`
`And again, as with Ground 1, even if not in the same plane or layer, the
`
`separate “arrayed along” requirement must imply being adjacent to one another and
`
`some overlap in at least one of the interconnections. And in sharp contrast to the
`
`
`

`PATENT OWNER REPLY
`
`relationship between the electrodes and interconnections in the ’338 patent claims
`
`
`
`
`
`and specification, Childs simply does not meet this limitation.
`
`Samsung’s IPR fails in its entirety.

`
`Samsung’s Theories and Assertions Under Ground I-- Obviousness
`Over Kobayashi in View of Shirasaki—Fail as a Matter of Law
`A. Merely Showing Supposed Interconnections Formed Anywhere Above a
`Surface of A Substrate—as Samsung Admittedly Did—Does Not Show
`“Interconnections Formed to Project From” That Surface
`Samsung’s Reply only further exposes the fact that Samsung has failed to
`
`show a plurality of interconnections “formed to project from” a surface of the
`
`transistor array substrate.” In its first ground, Samsung relies solely on Kobayashi to
`
`satisfy this express claim requirement and all of 1[b], for that matter. But even a
`
`cursory glance at Kobayashi shows that Samsung’s theories must fail. That is
`
`because, whatever spatial relationships Kobayashi’s supposed interconnections have
`
`with the surface of the transistor array substrate, they demonstrably do not “project
`
`from” that surface. This claim requirement—"project from” has a meaning -Each
`
`word must means something. The element is not “formed to project upward, from a
`
`surface” or formed away from a surface” or “formed to project with respect to a
`
`surface” or something as broad as (d) above…”. Instead, it is formed “to project
`
`from a surface.”

`PATENT OWNER REPLY
`
`Like all words and phrases, “formed to project from” has a meaning—and that
`
`
`
`meaning has its limits. Notably, the patentee did not employ the phrases (a) “formed
`
`to project upward” or (b) “formed to project above a surface;” or “formed to project
`
`with respect to a surface.” None of these phrases mean the same thing as the actual
`
`claim requirement, "formed to project from a surface.”
`
`This is where Samsung’s problems become insurmountable, because its
`
`theories rest on an interpretation that is several steps broader and more dissimilar to
`
`the actual claim requirement than either (a) – (c) above. As Samsung’s expert
`
`admitted during deposition, to make Kobayashi satisfy the claim requirements,
`
`Samsung misinterpreted the actually claimed phrase, formed to “project from a
`
`surface” to merely require that the interconnections are (d) formed anywhere
`
`“above” a surface:

`PATENT OWNER REPLY
`
`While the parties agree that being formed above a surface is necessary to being
`
`
`
`formed to project from that surface, it is not sufficient to project from that surface.
`
`Stated differently, an interconnection that projects from a surface must be formed
`
`above that surface, but not all interconnections formed above a surface will also
`
`project from it.
`
`Thus, the claim term “from” introduces an obvious additional spatial
`
`requirement beyond just being located above a surface. Specifically, the surface
`
`must also be a “starting point” from which the interconnection projects. See, e.g.,
`
`https://www.merriam-webster.com/dictionary/from (“a function word to indicate a
`
`starting point of a physical movement or a starting point in measuring or reckoning
`
`or
`
`in

`statement
`
`of
`
`limits”);
`
`https://dictionary.cambridge.org/us/dictionary/english/from (“used to show the
`
`place where someone or something starts) (emphasis added).
`
`But Samsung’s theory entirely ignores out the notion of projecting from a
`
`starting point in space—in this case, the surface of the transistor array substrate. That
`
`fails as a matter of law, because “[e]ach element contained in a patent claim is
`
`deemed material to defining the scope of the patented invention.” Warner-Jenkinson

`
`A look at Samsung’s visual demonstrative of its claim interpretation and claim
`
`
`
`mapping does not pass the eyeball test. According to Samsung, the uppermost layer
`
`of the “transistor array substrate” in Kobayashi is “insulating layer 116,” and the
`
`interconnections are the “auxiliary wiring elements 118.” (Petition at 44–46.) Using
`
`Samsung’s own annotated figure, the “transistor array substrate” under petitioner’s
`
`theory is highlighted in orange, and the “interconnections” are highlighted in red.
`
`
`
`
`
`
`This picture alone tells the full story. It is true that the red-annotated “auxiliary
`
`wiring elements 118” are formed above the orange-annotated substrate. But the
`
`wiring elements 118 are not “projecting from” it, as expressly required by the
`
`claim. Samsung’s theory must fail.

`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`
`To illustrate this point further, under Samsung’s merely “above” the surface
`
`application of the claims, other parts of Figure 7 would also “project from” the
`
`surface of the transistor array substrate. For instance, 122 would also “project”
`
`from the substrate, by virtue of being in the same device and merely “above” it.
`
`
`
`But this obviously fails—and only proves that Samsung is ignoring requirements of
`
`
`
`the claim.
`
`
`
`To be sure, the district court’s claim construction does not change this failure
`
`one bit. The dispute between the parties did not concern the term “from” and its
`
`spatial requirements, which the district court certainly did not purport to eliminate
`
`from the claim. Instead, the dispute went to whether the claimed “surface” had to be
`
`“the upper surface” of the transistor array substrate or any “exterior surface.”

`PATENT OWNER REPLY
`
`Markman Order at 15. The district court ruled that the claimed surface had to be “an
`
`
`
`
`
`outer surface”—id. at 18—but that ruling is irrelevant to Samsung’s failure to show
`
`projecting “from” as expressly required by the claims.
`
`And at any rate, merely being formed above the surface of the substrate plainly
`
`does not meet any reasonable application of the district court’s construction, which
`
`requires “extending beyond an outer surface” of the substrate.
`
`Unable to deal with this failure directly, Samsung’s Reply injects a second red
`
`herring based on other district court rulings. In particular, Samsung suggests that the
`
`district court “struck” expert testimony making the argument that Kobayashi did not
`
`satisfy limitation 1[b] because the auxiliary wiring elements of Kobayashi are not in
`
`physical contact or near the transistor array substrate. Reply at 15. This argument
`
`both mischaracterizes the district court’s order and overlooks the fact that the district
`
`court actually allowed almost precisely the opinion Samsung says was excluded.
`
`Mr. Credelle’s expert report in district court devotes seven paragraphs to
`
`Kobayashi and limitation 1[b], Ex. 1024, ¶¶ 219–225. Of these paragraphs, two of
`
`them provide his opinions about why the specific disclosure of Kobayashi does not
`
`satisfy limitation 1[b]. Ex. 1024, ¶¶ 222, 225. The district court did not strike either
`
`of these paragraphs. In particular, the district court did not strike any of paragraph
`
`222 of Mr. Credelle’s report, where he opines that the auxiliary wiring elements of
`
`Kobayashi do not satisfy the limitation because “[t]hey do not contact the surface of
`
`
`
`8
`
`
`
`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`the transistor array substrate and are not even close to doing so.” Ex. 1024, ¶ 222.
`
`
`
`
`
`This is, in substance, the argument that Samsung argues was stricken, but under the
`
`district court’s orders Mr. Credelle will be permitted to make exactly this argument
`
`to the jury at trial, along with the other arguments in the six paragraphs concerning
`
`Kobayashi and limitation 1[b] that were not stricken.
`
`The sole paragraph of Mr. Credelle’s Kobayashi opinions that the district
`
`court excluded was paragraph 221, which never mentions Kobayashi at all and does
`
`not directly argue it is missing any claim limitation. Rather, the paragraph contains
`
`Mr. Credelle’s opinions concerning the correct construction of the term—a term that
`
`the district court had already construed. The district court explained that it was
`
`excluding the testimony precisely because it was claim construction testimony,
`
`intruding on the district court’s role to construe the claims, not because it was
`
`substantively wrong. (Ex. 1026 at 88:11–16 (“However, with regard to the claim
`
`construction testimony of Mr. Credelle, particularly as located in Paragraph 221 of
`
`his report, I find that that is improper. It’s an attempt to impose what he considers
`
`the plain and ordinary meaning to the Court's adopted construction.”); Ex. 1027 at 9
`
`(“the Court GRANTED the Motion as it related to Mr. Credelle’s opinions on claim
`
`construction and the Court struck ¶ 221 of Mr. Credelle’s report”); see also Ex. 1020
`
`(“Likewise, the parties are ordered to refrain from mentioning any portion of this
`
`
`
`9
`
`
`
`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`[claim construction order], other than the actual definitions adopted by the Court, in
`
`
`
`
`
`the presence of the jury.”)).
`
`Because the district court did not strike the substance of Mr. Credelle’s
`
`opinions concerning Kobayashi and indeed permitted Mr. Credelle to make the
`
`substantive argument that Samsung complains about, the Board should likewise
`
`consider the argument and reject Samsung’s petition.
`
`
`
`Continuing its trend of distracting from the claim language, Samsung also
`
`suggests it can ignore the “from” requirement because “Solas’s argument is
`
`contradicted by the ’338 patent disclosures; including the specification’s preferred
`
`embodiment.” Reply at 17. Not so. Because the claims at issue use the “comprising”
`
`transition, there is no reason that every “interconnection” in a preferred embodiment
`
`would need to satisfy the term “project from a surface of the transistor array
`
`substrate.”
`
`But even if we assume that interconnection 91 must satisfy this claim
`
`limitation, it does not follow that the auxiliary wiring elements 118 of Kobayashi do
`
`as well. (Ex. 2005, ¶ 98.) We can see the significant difference between the two
`
`structures by comparing the following highlighted portions of the ’338 patent (left)
`
`and Kobayashi (right) figures from the Petition:

`

`PATENT OWNER REPLY
`
`
`
`
`The common interconnections 91 could reasonably be understood by a POSITA to
`
`“project from a surface” of the yellow transistor array substrate. (Ex. 2005, ¶ 99.)
`
`They begin near that surface and extend a significant distance away from the surface,
`
`both relative to their distance from the surface and relative to their overall
`
`dimensions. (Id.) The auxiliary wiring elements 118 in Kobayashi, on the other hand,
`
`do not “project from a surface” of the yellow layers. (Id.) They are far above the
`
`surface, relative to their own dimensions, and their extent in the vertical direction
`
`(the direction they would need to be “projecting” or “protruding” is small relative to
`
`the other relevant dimensions. (Id.)
`
`For these reasons, a POSITA would understand that the “auxiliary wiring
`
`elements 118” of Kobayashi do not satisfy the “project from a surface” requirement,
`
`under its plain meaning or as construed by the district court. (Ex. 2005, ¶ 101.)

`B.
`
`Samsung Also Fails to Show the Supposed Pixel Electrodes
`“Arrayed Along” Any Interconnections—and Samsung’s
`Theories Render That Separate Claim Requirement Meaningless
`Samsung also fails to show that Kobayashi in view of Shirasaki renders
`
`limitation 1[c] obvious. Samsung’s Petition relies solely on Kobayashi to satisfy
`
`1[c]. (Petition at 46–48.) But notwithstanding Samsung’s hand-waiving and other
`
`distractions, Kobayashi does not teach all three separate requirements of 1[c]. And
`
`Samsung’s theories otherwise merely render one, if not two, of these requirements
`
`superfluous and meaningless.
`
`According to the Petition and Samsung’s Reply, the pixel electrodes are the
`
`“first electrodes 117,” and the interconnections are the “auxiliary wiring elements
`
`118.” (Petition at 46–48.)

`PATENT OWNER REPLY
`
`As shown in Samsung’s annotated figure, its alleged “pixel electrodes” are
`
`
`
`
`
`highlighted in green, and alleged “interconnections” are highlighted in red.
`
`On this issue, both sides agree on the relevant claim construction for claim
`
`requirement 1[c]. That construction undoubtedly has three separate requirements,
`
`which are highlighted below:
`
`
`
`Applying this construction, it cannot reasonably be disputed that Kobayashi’s first
`
`electrode 117 must meet three separate requirements. 117 must be (i) arrayed along
`
`auxiliary wiring elements 118; and (ii) located between the auxiliary auxiliary
`
`wiring elements 118; and (iii) on the surface of the transistor array substrate.
`
`But as explained in Solas’s POR and its supporting materials, the first
`
`electrode 117 in Kobayashi are not (i) “arrayed along” or (ii) “located between” the
`
`auxiliary wiring elements 118, as those terms would be understood by a POSITA.
`
`(Ex. 2005, ¶ 104.)
`
`Samsung’s Reply makes at least Samsung’s failure to show the (i) “arrayed
`
`along” claim requirement abundantly clear. Samsung admits that 117 is not coplanar
`
`
`
`13
`
`
`
`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`with 118. Indeed, 117 and 118 do not share any overlapping layers in the formation
`
`
`
`
`
`of the entire package. Reply at 20. This point is confirmed with one look at
`
`Samsung’s demonstrative:
`
`
`
`Even if we were to just accept—despite what our eyes can see—Samsung’s
`
`assertion that 117 and is (ii) located between 118; and (iii) on the surface of
`
`substrate—that would still leave one question unresolved for any POSITA. That is:
`
`how can any POSITA view 117 as being (i) “arrayed along” 118? As explained by
`
`Mr. Flask—in an declaration that Samsung did not respond to—the answer is
`
`obvious to the naked eye: A POSITA cannot, and would not, view it this way.

`
`Co., 520 U.S. 17, 29, 117 S.Ct. 1040, 137 L.Ed.2d 146 (1997). And here, “arrayed
`
`along” has to mean and require something beyond the other requirements of 1[c].
`
`As the record in this proceeding has now established, any POSITA would understand
`
`this plain requirement of being arrayed “along” to demand a showing that the
`
`electrode is arrayed “in an line matching the length or direction of” the
`
`interconnections. https://www.merriam-webster.com/dictionary/along) see also
`
`https://dictionary.cambridge.org/us/dictionary/english/along (in a line next to
`
`something long) (emphasis added).The patent specification demands this as well.
`
`That intrinsic record describes the process of elements of the preferred embodiments
`
`being formed or arrayed alongside others. Ex. 1001 at 2:45–47; 5:61–6:2; 7:44–8:15;
`
`10:48–11:65; 12:30–13:17; Figs. 1, 3–6
`
`
`
`This applies equally in the context and description of pixel electrodes being
`
`arrayed alongside the claimed plurality of interconnections—as shown by
`
`Samsung’s own demonstrative:

`
`
`
`
`But Samsung’s petition does not show this 117 and 118 being . To the
`
`contrary, by design, elements 117 is several horizontal layers below from elements
`
`118. Indeed, the plain language of the ’338 patent claims—and even the description
`
`of the embodiments in the patent—stands in stark contrast with Samsung’s claim
`
`mapping with Kobayashi:

`PATENT OWNER REPLY
`
`
`
`
`Even if we can look past Samsung’s hand-waiving on the requirement that
`
`elements 117 be located between elements 118, that does not also separately get them
`
`elements 117 being “arrayed along” elements 118. Even if not in the same plane or
`
`layer, the separate “arrayed along” requirement must imply being adjacent to one
`
`another and some overlap in at least one of the interconnections. And in sharp
`
`contrast to the relationship between the electrodes and interconnections in the ’338
`
`patent claims and specification, Kobayashi’s elements 117 are not along or even
`
`adjacent to elements118.
`
`Thus, Samsung’s claim mapping entirely reads out this separate requirements.
`
`That fails. Indeed, any applications of the claims that “that render some portion of

`
`
`
`
`Put differently, Samsung’s interpretation—which requires only that the electrodes
`
`elements 117 be at a lower layer, even those not adjacent to or not overlapping with
`
`any layer shared by any wiring elements 118—would indistinguishably render 104,
`
`105, and 114 all “arrayed along” 118. That just does not fly.
`
`For its part, Samsung’s Reply presents only a single argument in a single
`
`paragraph on this point. Reply at 20-21. In that paragraph,. Samsung builds a
`
`strawman and misunderstands Solas’s plain meaning interpretation as requiring
`
`electrodes and interconnections be “coplanar.” Based on this strawman, Samsung
`
`again contends that Solas’s arguments are contradicted by the disclosures of the ’338
`
`patent. Id.

`
`But the specification does nothing to support this contention. Samsung claims
`
`
`
`that a sentence in the disclosure proves that pixel electrodes do not need to be
`
`adjacent to or share any overlapping horizontal portions with any interconnections.
`
`But the sentence Samsung quotes is directed to a single embodiment and, incredibly,
`
`does not even mention the phrase “arrayed along.” Reply at 21. In any event, that
`
`embodiment, in Figure 6, clearly does not support Samsung’s argument—it shows
`
`the green pixel electrodes sharing overlapping horizontal portions with a plurality of
`
`interconnections 90 and 89—and even shows it right adjacent to the third
`
`interconnection 91:
`
`Moreover, the sentence to which Samsing cites refers to Figure 2 in any event.
`
`Accordingly, Samsung’s petition must fail—as a matter of law—for this
`
`second independent reason.

`III. Samsung’s Theories and Assertions Under Ground II-- Obviousness
`Over Childs in View of Shirasaki—Fail For Similar Reasons
`Samsung Plainly Does Not and Cannot Show “a plurality of pixel
`electrodes “on the surface of the transistor array substrate”
`Samsung has not established that Childs in view of Shirasaki renders
`
`A.
`
`limitation 1[c] obvious.1 (Petition at 69–75.) The Petition does not argue that
`
`Shirasaki teaches this limitation. (Petition at 69–75.). Under Samsung’s theory, the
`
`transistor array substrate is all layers of Childs up to the “planar insulating layer 12,”
`
`the interconnections are the “conductive barrier[s] 240,” and the pixel electrodes are
`
`the “lower electrode[s] 21” (Petition at 64, 68–70.)

`
`
`
`
`As discussed above, in the parallel district court case, the parties agreed to
`
`construe the phrase “the pixel electrodes being arrayed along the interconnections
`
`between the interconnections on the surface of the transistor array substrate” as “the
`
`pixel electrodes are (i) arrayed along the interconnections and (ii) located between
`
`the interconnections, and (iii) the pixel electrodes are on the surface of the transistor
`
`array substrate.” (Ex. 1020 at 8.)
`
`But Childs does not satisfy this limitation under this agreed construction. (Ex.
`
`2005, ¶ 133.)) “Lower” electrodes (green) are not “on the surface” of the transistor
`
`array substrate (orange). (Id.) Instead, large portions of the pixel electrodes are
`
`buried under and in the alleged substrate. (Id.)
`
`One look at the patent specification proves this beyond reasonable debate.
`
`While Samsung expressly relies in Figure 2, the reference makes clear that the lower
`
`
`
`22
`
`
`
`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`electrode 21 is not on any surface of the substrate. Just the opposite is true. Childs
`
`
`
`
`
`clearly explains that The “Figures 2 and 3 illustrate a LED construction in which the
`
`lower electrode 21 is formed as a thin film in the circuit substrate 100. Indeed, it
`
`then states that “the subsequently-deposited organic semiconductor material 22
`
`contacts this thin-film electrode layer 21 at a window 12a in a planar insulating layer
`
`12 (for example of silicon nitride) that extends over the thin-film structure of the
`
`substrate 100.”
`
` Recognizing this fatal problem, Petition proposes modifying Childs by
`
`placing the lower electrodes 21 on top of another insulating layer, either an added
`
`
`
`
`
`23
`
`
`
`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`layer not already in Childs or on top of upper planar insulating layer 12. The
`
`
`
`
`
`petitioner and/or Dr. Fontecchio propose combining Childs with one of Kobayashi,
`
`Nakamura, or Park to add this insulating layer. (Petition at 72–75.) But neither any
`
`of these references nor the Fontecchio declaration identify any benefit to adding this
`
`insulating layer to Childs’s existing design. (Ex. 2005, ¶ 134.) Adding this layer will
`
`require further deposition and photolithography steps and will increase the cost of
`
`the device. (Id.) In addition, in Kobayashi at least, the additional insulating layers
`
`are made from silicon nitride. Dr. Fontecchio opines that silicon nitride is opaque
`
`and therefore, it would block the light 250 emitted from the EL element. (Ex. 1018,
`
`¶ 187; Ex. 2007 at 72:12–14 (“Q. And is silicon nitride an opaque material that
`
`would block visible light? A. It is.”), at 127:14–23 (“Q. Why do you think that Childs
`
`identifies silicon nitride as the first choice to use for that material -- for that layer
`
`rather? A. Oh, to block light. I think it’s probably the most likely reason. Q. And
`
`why would the designer Childs want layer 12 to block light? A. So that you don't
`
`get extra light onto the transistor elements and probably parts. Also so you just
`
`have control over it.”).)
`
`No reason for incurring these costs and disadvantages is provided other than
`
`to follow the approach claimed in the ’338 patent. (Ex. 2005, ¶ 135.) Dr. Fontecchio
`
`argues that other references like Inukai and Arai teach that it is important to have a
`
`level insulator surface on which to deposit the pixel electrodes. (Id.) But a POSITA
`
`
`
`24
`
`
`
`IPR2020-00320 (’338 Patent)
`PATENT OWNER REPLY
`
`would not see this as a reason to modify Childs, because the surface of Childs that
`
`
`
`
`
`the pixel electrodes are deposited on is insulating layer 8, which is already flat in the
`
`areas where the pixel electrodes are deposited, as shown in Childs Figure 2. (Id.)
`
`B.
`
`Samsung Again Also Fails to Show the Supposed Pixel Electrodes
`“Arrayed Along” Any Interconnections—and Petitioner’s
`Theories Render That Separate Claim Requirement Meaningless
`In addition, the pixel electrodes (green) are not “arrayed along” or “located
`
`between” the interconnections (pink). (Id.) In fact, parts of the pixel electrodes are
`
`almost directly beneath the interconnections. (Id.) Thus, even if a POSITA were
`
`motivated to add an additional insulating layer to Childs, it would not satisfy this
`
`limitation, because the resulting pixel electrodes (green) would not be “arrayed
`
`along” or “located between” the interconnections (pink). (Ex. 2005, ¶ 136.) For
`
`example, the Kobayashi combining reference does not have electrodes “along” and
`
`“between” the interconnections, as discussed above. (Id.) Neither the Petition nor
`
`Dr. Fontecchio has identified interconnections in any of Nakamura, Park, Inukai, or
`
`Arai or explained how combining with them would produce electrodes “along” and
`
`“between” the interconnections. (Id.)
`
`Again, as with Ground 1, even if not in the same plane or layer, the separate
`
`“arrayed along” requirement must imply being adjacent to one another and some
`
`overlap in at least one of the interconnections. And in sharp contrast to the
`
`

`PATENT OWNER REPLY
`
`relationship between the electrodes and interconnections in the ’338 patent claims
`
`
`
`
`
`and specification, Childs simply does not meet this limitation.
`
`Thus, Samsung’s claim mapping entirely reads out this separate requirements.
`
`That fails. Indeed, any applications of the claims that “that render some portion of
`
`the claim language superfluous are disfavored.” Power Mosfet Techs. LLC, v.
