`
`
`PRELIMINARY STATEMENT
`Petitioner Tianma Microelectronics Co., Ltd. requests inter partes review of
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`I.
`
`claims 1–2 of U.S. Patent No. 10,330,989 (Ex. 1001), assigned to Patent Owner
`
`Japan Display, Inc. (“JDI”). Claim 1 is directed to a liquid crystal display (“LCD”)
`
`device. The LCD device includes a “counter electrode” having a “planer shape”
`
`that is “connected to [a] common layer via a through hole in [an] organic insulation
`
`layer.” ’989 patent, 52:8–34. And the LCD device also includes a “pixel electrode”
`
`having a “slit” with a “first portion [that] is not parallel with [a] gate line and [a]
`
`drain line” of the device. Id., 52:25–27. But none of this was new.
`
`Planar counter electrodes were known before the earliest priority date of the
`
`’989 patent, as demonstrated by Yuh, as were pixel electrodes having slits not
`
`parallel with gate lines and drain lines in LCD devices, as demonstrated by Abe
`
`and Kurahashi. The connection of a counter electrode to a common layer via a
`
`through hole in an organic insulation layer was likewise known, as demonstrated
`
`by Ohta and Kurahashi. Claim 2 adds that a “common layer” of the device “is a
`
`planer shape,” ’989 patent, 52:35–37, but planar common layers were also known,
`
`as demonstrated by Kim.
`
`As described below, Yuh, in combination with Abe, Ohta, Kurahashi and/or
`
`Kim, renders obvious claims 1–2 of the ’989 patent.
`
`
`

`
`
`
`II. THE ’989 PATENT
`The ’989 patent describes “[a] liquid crystal display device” that includes “a
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`first substrate,” “a second substrate,” and a “liquid crystal layer between the first
`
`substrate and the second substrate, containing liquid crystal molecules.”
`
`’989 patent (Ex. 1001), 1:55–61, 52:8–12. As shown in Figure 61, formed on the
`
`first substrate are each of: “a common layer,” “an organic insulation layer,” “a
`
`counter electrode,” “a gate insulation layer,” “a pixel electrode,” and “a drain line.”
`
`Id., 52:13–29. “[T]he counter electrode is connected to the common layer via a
`
`through hole within the organic insulation layer.” Id., 52:32-34.
`
`
`
`’989 patent, Figure 1 (annotated, Flasck (Ex. 1003), ¶33).
`
`Figure 60 illustrates a plan view of the device shown in Figure 61. As
`
`shown, the device further includes “a gate line.” ’989 patent, 52:13. “[T]he counter
`2
`
`
`
`
`
`electrode is a planer shape, and the pixel electrode comprises a slit having a first
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`portion, and the first portion is not parallel with the gate line and the drain line.”
`
`Id., 52:24–27. Additionally, “the common layer is a planer shape” and “faces
`
`plural of the pixel electrode.” Id., 52:35–37.

`
`
`
`III. LEVEL OF ORDINARY SKILL IN THE ART
`A person of ordinary skill in the art (“POSA”) would have had at least a
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`four-year undergraduate degree in electrical engineering or physics or a closely
`
`related field and four years of experience in the design and implementation of flat
`
`panel display devices or components thereof. Flasck, ¶38. Additional education
`
`could substitute for professional experience and vice versa. Id.
`
`IV. THE BOARD SHOULD NOT EXERCISE ITS DISCRETION TO
`DENY INSTITUTION
`A. The Board Should Not Deny Institution Under 35 U.S.C. § 314
`The ’989 patent was asserted against Tianma in Japan Display Inc. f/k/a
`
`Hitachi Electronic Devices (USA), Inc. et al. v. Tianma Microelectronics Co. Ltd.,
`
`No. 2:20-cv-00283 (E.D. Tex.) (the “related district court litigation”). See infra
`
`Section VIII.B. The -00283 case is only one of three cases filed against Petitioner
`
`by Patent Owner on the same day. Ex. 1011. Patent Owner has asserted fifteen
`
`patents across the three now-consolidated cases. Ex. 1011; Ex. 1014.
`
`The most relevant Fintiv factors demonstrate that the Board should not deny
`
`institution under 35 U.S.C. § 314(a) and Apple Inc. v. Fintiv, Inc., IPR2020-00019,
`
`Paper 11 (PTAB Mar. 20, 2020) (precedential) (“Fintiv”). The current docket control
`
`order in the related district court litigation sets trial in February 2022 (Ex. 1015 at
`
`1), before the statutory deadline for Final Written Decision, but this is not
`
`
`
`5
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`determinative. Taken as a whole, Factors 4 (lack of overlap) and 6 (strong merits)
`
`outweigh the other relevant factors, and the Board should therefore institute.
`
`Regarding Factor 1, where, as here, a stay has been neither requested nor
`
`granted, “[t]his factor does not weigh for or against discretionary denial.” Apple Inc.
`
`v. Fintiv, Inc., IPR2020-00019, Paper 15 at 12 (PTAB May 13, 2020). Nor should
`
`the Board, in the absence of specific evidence, speculate how the district court will
`
`proceed with respect to any motion. See, e.g., Sand Revolution II, LLC v. Cont’l
`
`Intermodal Grp.-Trucking LLC, IPR2019-01393, Paper 24 at 7 (PTAB June 16,
`
`2020) (“In the absence of specific evidence, [the Board] will not attempt to predict
`
`how the district court in [a] related district court litigation will proceed . . . .”); Dolby
`
`Lab’ys, Inc. v. Intertrust Techs. Corp., IPR2020-00664, Paper 10 at 10-11 (PTAB
`
`Dec. 8, 2020) (declining to speculate whether the district court may or may not grant
`
`any motion to stay). Moreover, it remains uncertain when and where the related
`
`district court litigation will even be tried because Petitioner has moved to transfer
`
`the litigation. Ex. 1016. See, e.g., Quantile Techs. Ltd. v. TriOptima AB, CBM2020-
`
`00012, Paper 11 at 17 (PTAB Oct. 5, 2020) (petitioner’s pending motion to change
`
`venue in related district court litigation relevant to weighing factor 1 neutrally).
`
`Thus, Factor 1 is, at best, neutral.
`
`Regarding Factor 2, the current docket control order in the related district
`
`court litigation sets trial in February 2022 (Ex. 1015 at 1), and thus before the
`6
`
`
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`Board’s anticipated statutory deadline for a final written decision. Given Petitioner’s
`
`motion to transfer, however, that trial date is speculative. See, e.g., Quantile Techs.,
`
`Paper 11 at 18 (Petitioner’s pending motion to change venue in a related district
`
`court litigation relevant to weighing factor 2); Dish Network L.L.C. v. Broadband
`
`iTV, Inc., IPR2020-01359, Paper 15 at 13-16 (PTAB Feb. 12, 2021) (petitioner’s
`
`pending motion to transfer in a related district court litigation relevant to weighing
`
`factor 2). Moreover, in light of the Board’s holistic analysis balancing all the Fintiv
`
`factors, the trial date of the related district court litigation is not determinative but
`
`weighed in concert with the other relevant factors. See, e.g., Samsung Elecs. Co. v.
`
`Acorn Semi, LLC, IPR2020-01183, Paper 17 at 38-39, 47 (PTAB Feb. 10, 2021)
`
`(instituting review when related district court litigation trial date more than ten
`
`months before final written decision date); Consentino S.A.U. v. Cambria Co.,
`
`PGR2021-00010, Paper 11 at 10-11, 16 (PTAB May 18, 2021) (same by seven
`
`months); Medtronic CoreValve LLC v. Colibri Heart Valve LLC, IPR2020-01454,
`
`Paper 11 at 12-13, 18-19 (PTAB Mar. 10, 2021) (same by six months); Lego Sys.,
`
`Inc. v. MQ Gaming LLC, IPR2020-01443, Paper 12 at 7-8, 16-17 (PTAB Feb. 17,
`
`2021) (same by five months).
`
`Regarding Factor 3, although there has been some investment by the parties
`
`in the related district court litigation, based on the current docket control order
`
`(Ex. 1015), a substantial portion of work and trial is yet to come after institution. By
`7
`
`
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`institution, the primary investment by the district court will be through any claim
`
`construction ruling, but any such ruling will have no overlap with the present IPR as
`
`none of the disputed terms are from this patent (Ex. 1013). See, e.g., Lego Sys., Paper
`
`12 at 10-11 (finding the lack of any proposed claim terms for construction in the
`
`district court litigation relevant to weighing Factor 3).
`
`Moreover, Petitioner moved with speed and diligence in bringing this
`
`challenge—the Petition is being filed five months after Patent Owner served its
`
`infringement contentions—mitigating against the investment of the parties. See, e.g.,
`
`Dolby Lab’ys, Paper 10 at 17-18 (finding petitioner acted diligently in filing petition
`
`about three months after patent owner served its infringement contentions
`
`identifying the asserted claims); Fintiv, Paper 11 at 11 (“If the evidence shows that
`
`the petitioner filed the petition expeditiously, such as promptly after becoming aware
`
`of the claims being asserted, this fact has weighed against exercising the authority
`
`to deny institution under NHK.”). To be sure, “preparing a petition for inter partes
`
`review requires substantial effort even after the references and basic theories have
`
`been identified.” Lego Sys., Paper 12 at 11. And this is particularly true in view of
`
`the large number of patents and claims challenged in this and Petitioner’s other
`
`related (see infra Section VIII.B) and upcoming petitions for IPR. See Lego Sys.,
`
`Paper 12 at 11-12; Sotera Wireless, Inc. v. Masimo Corp., IPR2020-01019, Paper 12
`
`at 17 (PTAB Dec. 1, 2020) (“[W]e find that Petitioner’s explanation for the timing
`8
`
`
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`of the Petition is reasonable, notwithstanding the closeness to the statutory deadline,
`
`particularly in view of the large number of patents and claims challenged in this and
`
`Petitioner’s other related petitions for inter partes review.”).
`
`Moreover, in its complaints, Patent Owner asserted “at least claim 1” from
`
`each of fifteen asserted patents, totaling over 170 claims, against five products.
`
`Ex. 1011. And Patent Owner refused to narrow the number of claims and issues until
`
`service of its infringement contentions (Ex. 1012). And then, when Patent Owner
`
`did identify the full set of asserted claims in its contentions, it alleged infringement
`
`of over 2,400 products, imposing a vastly greater burden on Petitioner to assess the
`
`dispute and evaluate on which patents to request IPR. Ex. 1012. See, e.g., Fintiv,
`
`Paper 11 at 11 (“[I]t is often reasonable for a petitioner to wait to file its petition
`
`until it learns which claims are being asserted against it in the parallel proceeding.”);
`
`Samsung Elecs., Paper 17 at 40 (“We recognize that much work has been done by
`
`the parties in the District Court. However, we also find, as a countervailing
`
`consideration, that Petitioner acted diligently in filing this and the other IPRs. The
`
`record reflects that Patent Owner did not identify the full set of claims being asserted
`
`in the District Court until March 9, 2020, and that Petitioner filed this Petition, and
`
`nine others, in less than four months.” (citation omitted)); Dish Network, Paper 15
`
`at 19-20 (petitioner filing petition within three months after receiving patent owner’s
`
`infringement positions for all asserted claims (including those not specifically
`9
`
`
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`identified originally in the complaint) and prior to completion of Markman briefing);
`
`Lego Sys., Paper 12 at 11-12. “Because Petitioner acted diligently and without much
`
`delay, this mitigates against the investment of the parties.” Dolby Lab’ys, Paper 10
`
`at 17 (citing Apple Inc. v. Seven Networks, LLC, IPR2020-00156, Paper 10 at 11-12
`
`(PTAB June 15, 2020)).
`
`Regarding Factor 4, Petitioner stipulates that, if this IPR is instituted, it will
`
`not pursue in the related district court litigation any ground that it raised or
`
`reasonably could have raised in this Petition. Thus, there will not be any overlap
`
`between this Petition and potential invalidity grounds in the related district court
`
`litigation, strongly weighing in favor of institution. See Sotera Wireless, Paper 12 at
`
`18-19 (precedential as to Section II.A) (finding that because the stipulation
`
`“mitigates any concerns of duplicative efforts” and “potentially conflicting
`
`decisions,” this factor strongly favors institution); see also Consentino, Paper 11 at
`
`13-15 (“Considering that Petitioner has agreed to be bound by a stipulation that is
`
`substantively the same as the stipulation addressed in Sotera, we follow the Sotera
`
`precedent in finding that this factor weighs strongly against exercising discretion to
`
`deny.”); Bos. Sci. Corp. v. Nevro Corp., IPR2020-01562, Paper 14 at 24 (PTAB Mar.
`
`16, 2021); Medtronic CoreValve, Paper 11 at 17; Lego Sys., Paper 12 at 12-15.
`
`Factor 6 favors institution because the merits of this Petition are strong. The
`
`Petition relies upon materially different and noncumulative references not applied
`10
`
`
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`during prosecution that teach the very features that Patent Owner argued and the
`
`examiner found missing, and which led to the allowance of the claims—i.e.,
`
`“wherein the counter electrode is connected to the common layer via a through hole
`
`within the organic insulation layer.” See infra Section IV.B. This is also Petitioner’s
`
`only challenge to the ’989 patent that has ever been or is currently before the Board,
`
`making considerations related to follow-on petitions moot.
`
`At bottom, this first and only IPR challenge on the ’989 patent raises
`
`different issues than the related district court litigation (Factor 4) and the petition is
`
`strong on the merits (Factor 6), which outweighs other applicable factors, including
`
`the current trial date in the related district court litigation. Moreover, Petitioner
`
`expeditiously filed this IPR Petition—and other related and upcoming petitions—
`
`five months after Patent Owner’s infringement contentions. The Board should
`
`therefore institute this IPR. See Samsung Elecs., Paper 17 at 47 (“We determine
`
`that Petitioner’s stipulation has minimized any overlap with the parallel district
`
`court litigation such that both the duplication of efforts and the potential for
`
`conflicting decisions are minimized. Although the parties have invested in the
`
`litigation, Petitioner filed this proceeding on a timely basis after learning which of
`
`the eighty-four claims were being asserted. Accordingly, we conclude that the
`
`minimization of overlap and the strength of the merits of the first challenge
`
`outweigh the upcoming trial date. As such, we decline to exercise discretion to
`11
`
`
`
`
`
`deny inter partes review.”); see also Lego Sys., Paper 12 at 16-17; Bos. Sci., Paper
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989

`
`The Board Should Not Deny Institution Under 35 U.S.C. § 325(d)
`B.
`Denial of institution would also be improper based on a weighing of the
`
`factors in Becton, Dickinson & Co. v. B. Braun Melsungen AG, IPR2017-01586,
`
`Paper 8 at 17-18 (PTAB Dec. 15, 2017),which include (a) the similarities and
`
`material differences between the asserted art and the prior art involved during
`
`examination; (b) the cumulative nature of the asserted art and the prior art
`
`evaluated during examination; (c) the extent to which the asserted art was
`
`evaluated during examination, including whether the prior art was the basis for
`
`rejection; (d) the extent of the overlap between the arguments made during
`
`examination and the manner in which Petitioner relies on the prior art; (e) whether
`
`Petitioner has pointed out sufficiently how the Examiner erred in his evaluation of
`
`the asserted prior art; and (f) the extent to which additional evidence and facts
`
`presented in the Petition warrant reconsideration of the prior art or arguments. See
`
`also Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH,
`
`IPR2019-01469, Paper 6 (PTAB Feb. 13, 2020) (precedential).
`
`Regarding factors (a) and (b), only Kim and Kurahashi were cited during
`
`prosecution, and neither was considered substantively by the examiner, let alone in
`
`
`
`12
`
`
`
`combination with any of Yuh, Ohta, or Abe. As Becton recognizes, it is not
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`assumed that a reference was substantively evaluated when “the prior art was
`
`simply listed in an IDS during prosecution.” Becton, Paper 8, 23. The proposed
`
`combinations based on Yuh are materially different from and not cumulative the
`
`Min, Lyu, and Kaneko references used to reject claims during prosecution at least
`
`because these combinations teach “wherein the counter electrode is connected to
`
`the common layer via a through hole within the organic insulation layer,”
`
`something the Examiner determined was missing from Min, Lyu, and Kaneko and
`
`was added to secure a Notice of Allowance. Ex. 1002, 209–214, 239, 247–48.

`
`the petition “present[ed] evidence that the asserted prior art [taught] the claim
`

`
`Regarding factors (c) and (d), because none of Yuh, Ohta, Abe, Kim, or

`
`A. Ground 1: Claims 1–2 Would Have Been Obvious Based on Yuh,
`Ohta, and Abe
`1. Overview of the Prior Art
`Yuh, Ohta, and Abe are analogous art to the ’989 patent. Each “is from the
`
`same field of endeavor,” LCD devices. Unwired Planet, LLC v. Google Inc., 841
`
`F.3d 995, 1000–01 (Fed. Cir. 2016) (citation omitted). Moreover, each is
`
`reasonably pertinent to “one of the particular problems dealt with by the inventor,”
`
`such as improving a holding capacity of an LCD device while maintaining aperture
`
`ratio, ’989 patent, 3:14–26, Yuh (Ex. 1005), 2:39–43 3:42–46, Ohta (Ex. 1006),
`
`16:17–64, and achieving a multi-domain effect in an LCD device, ’989 patent,
`
`41:35–57, Abe (Ex. 1007), 36:31–67. Flasck, ¶44.
`
`Yuh
`a.
`Yuh, U.S. Patent No. 6,577,368, was filed November 3, 1998, and
`
`constitutes prior art under at least pre-AIA 35 U.S.C. § 102(e).
`
`Yuh describes an LCD device, shown in Figure 2, that includes a lower
`
`substrate, an upper substrate, and a liquid crystal layer therebetween. Yuh, 7:1–3.
`
`Yuh’s device further includes a linear electrode (also called a pixel electrode) and a
`
`planar electrode (also called a common electrode), as well as an insulating film.
`
`

`
`
`Yuh, Figure 2 (annotated, Flasck, ¶46).
`
`A layout view of Yuh’s device is shown in Figure 35A. Yuh, 5:29–30. As
`
`shown, the pixel electrodes include slits, and the device also includes a gate line
`
`and a data line.

`
`
`
`
`

`
`
`
`Ohta describes an LCD device that, similar to Yuh’s, includes a pixel
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`electrode, a counter electrode, and a “liquid crystal composition formed between a
`
`lower-side substrate and an upper-side substrate.” Ohta, [0048]–[0049], [0057],
`
`[0092], [0095]. Ohta’s device also includes an insulating film and an organic
`
`passivation layer, as shown. Id., [0068], [0085].
`
`Ohta, Figure 2 (annotated, Flasck, ¶51).
`

`
`
`
`
`
`In Ohta, the voltage is applied to the counter electrode via a counter line
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`formed of a “conductive film,” such as a “chrome-molybdenum alloy.” Ohta,
`
`[0066]. Ohta’s counter line is illustrated in Figure 4. Id. As shown, the counter
`
`electrode is connected to the counter line via a through hole in the organic
`
`passivation layer. Id., [0092].
`
`
`
`Ohta, Figure 4 (annotated, Flasck, ¶52).
`
`Abe
`c.
`Abe, U.S. Patent No. 6,507,383, is a national stage of a PCT application
`
`having a § 102(e) date of June 29, 2001, and constitutes prior art at least under pre-
`
`AIA 35 U.S.C. § 102(e).
`
`
`
`19
`
`
`
`Abe describes an LCD device that, similar to Yuh’s, includes a pixel
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`electrode and a common signal electrode. Abe, Abstract, 19:37–54. Abe’s common
`
`signal electrode is planar, and Abe’s pixel electrode includes a slit. Abe, 19:8–17.
`
`In Abe, the “slit [has] a first portion ... not parallel with the gate line and the drain
`
`line,” as shown in Figure 29. According to Abe, this provides “a so-called multi
`
`domain system liquid crystal display unit” that prevents a “difference in
`
`coloration” that is “produced when a display area” not employing the multi-domain
`
`system “is viewed from right and left.” Id., 36:31–42.

`Yuh teaches “[a] liquid crystal display.” Yuh, 6:29–35.
`
`
`

`
`
`
`1(a). “a first substrate;”
`b.
`Yuh teaches “a first substrate.” Flasck, ¶¶73–74. Yuh describes a “lower

`
`
`substrate 100,” shown in Figure 2. Yuh, 6:29–35.
`
`Yuh, Figure 2 (annotated, Flasck, ¶73).
`

`c.
`Yuh teaches “a second substrate.” Flasck, ¶¶75–76. Yuh describes an “upper
`
`
`
`substrate 200,” shown in Figure 2. Yuh, 6:62–65.

`
`d.
`
`1(c). “a liquid crystal layer between the first substrate
`and the second substrate, containing liquid crystal
`molecules;”
`Yuh teaches “a liquid crystal layer between the first substrate and the second
`
`substrate, containing liquid crystal molecules.” Flasck, ¶¶77–79. Yuh describes “a
`
`liquid crystal layer 500 ... interposed between ... the substrates 100 and 200,” as
`
`shown in Figure 2. Yuh, 7:1–3. Yuh teaches that the liquid crystal layer “contain[s]
`
`
`
`23
`
`
`
`liquid crystal molecules.” Id., 7:66–8:3 (“When viewed on a plane parallel to the
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`
`substrates 100 and 200, the liquid crystal molecules ...”); Flasck, ¶77.
`
`
`
`Yuh, Figure 2 (annotated, Flasck, ¶78).
`
`1(d). “a gate line and a drain line;”
`e.
`Yuh teaches “a gate line and a drain line.” Flasck, ¶¶80–82. In Yuh, “a gate
`
`line 10 is formed on the substrate 100 and extends in the transverse direction,” and
`
`“[a] data line extending in the longitudinal direction is also formed,” as shown in
`
`Figure 35A. Yuh, 21:39–41, 22:4–6. A POSA would have understood the “data

`24
`
`
`
`IPR2021-01060 Petition
`U.S. Patent No. 10,330,989
`
`line 70” in Yuh to be a “drain line” because these terms were used interchangeably,
`
`as the ’989 patent itself recognizes. Flasck, ¶81; ’989 patent, 23:29–30 (“DL
`
`indicates drain lines (video signal lines or data lines)”).

`
`
`f.
`
`1(e). “a pixel electrode and a counter electrode
`disposed between the first substrate and the liquid
`crystal layer;”
`Yuh teaches “a pixel electrode and a counter electrode disposed between the
`
`first substrate and the liquid crystal layer.” Flasck, ¶¶83–88.
`
`Yuh describes a “pixel electrode,” which Yuh also calls a “linear electrode.”
`
`In Figure 2, for example, Yuh illustrates “a plurality of narrow linear electrodes 1.”
`
`Yuh, 6:50–54. Figure 35A depicts “linear pixel electrodes 75,” as shown. Id.,
`
`22:15–17.

`
`
`Yuh, Figure 35A (annotated, Flasck, ¶84).
`
`Yuh also describes a “counter electrode,” which Yuh calls a “planar
`
`electrode,” “common electrode,” or “planar common electrode.” In Figure 2, for
`
`example, Yuh illustrates “[a] planar electrode 2 ... formed on the ... lower substrate
`
`100,” as shown. Figures 35A and 35B (which is a cross-section of Figure 35A)
`
`
`

`
`
`
`shows a “planar common electrode” similarly “formed on a ... substrate 100,” as

`
`Yuh, Figure 35B (annotated, Flasck, ¶85).
`
`A POSA would have understood Yuh’s planar electrode (also called a
`
`common electrode or planar common electrode, hereinafter “planar electrode”) to
`
`be a “counter electrode,” as claimed. Flasck, ¶86. As shown in Yuh’s Figures 2 and
`
`35B and the ’989 patent’s Figure 61 below, just as the claimed “counter electrode”
`
`and “pixel electrode” are formed on the first substrate and separated by an gate
`
`insulation layer in the ’989 patent, Figure 61, 39:47–55, Yuh’s planar electrode and
`
`pixel electrode are formed on the
