      “prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (holding that absent evidence to the contrary, “the prior art itself [may] reflect[] an appropriate level” of ordinary skill in the art). In general, we agree with the areas of agreement in the parties’ proposals. In particular, Patent Owner proposes “at least a Bachelors’ degree in a field of engineering or physics,” which includes “electrical engineering or a comparable field of study” as Petitioner proposes. Pet. 4 (emphasis added); PO Resp. 10. We agree with Petitioner that by defining the engineering field as “electrical” or “comparable,” we can exclude engineering fields “having nothing to do with displays, such as biomedical, civil, chemical or environmental engineering.” Pet. Reply 1. Petitioner also proposes approximately “one or more years of professional experience” which includes Patent Owner’s “at least two years of professional experience.” Pet. 4; PO Resp. 10. Furthermore, both parties agree that “[a]dditional graduate education could [reduce . . . the time requirement] for professional experience.” Id. Thus, we adopt both parties’ proposed POSITA of having a Bachelors’ degree in electrical engineering or a comparable field of study, plus at least two years of professional experience, wherein additional graduate education could reduce the time requirement for professional experience. Id. Such proposal comports with the level of ordinary skill in the art reflected in the prior art of record.” slip op. at 10

      “The plain language in claim 1 of “auxiliary electrode” does not preclude that the “electrode” may be a power line, bus line, or resistor. Ex. 1001, 8:47–52. Nothing in the Specification clearly precludes “auxiliary electrode” from being a “bus line” or “power line,” as Patent Owner proposes. PO Resp. 25–27. We are unpersuaded by Patent Owner’s contention that the Specification discloses that “the power line ‘PL’ is shown in Figure 1, but the power line PL is not an electrode that is shown in Figure 2.” Id. at 26–27. Here, Patent Owner points to no portions in the Specification that provide the requisite “reasonable clarity, deliberateness, and precision” to warrant interpreting the claim language at issue as supporting Patent Owner’s contention that an auxiliary electrode cannot be a power line, bus line, or resistor. Id.; In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1984). That is, although Patent Owner points to Figures 1 and 2 of the Specification for support of its contention, Figures 1 and 2 of the Specification merely show various examples of power line and an auxiliary electrode. PO Resp. 26–27. Thus, although the referenced portions of the Specification discuss various examples wherein an auxiliary electrode may be implemented, nothing in these referenced portions of the Specification clearly precludes the “auxiliary electrode” from being a power line or any electrode that is “the road to get to an end point,” as Patent Owner contends. Id. Patent Owner points to no special definition, implicit or explicit, for “auxiliary electrode” that is set forth in the Specification which supports Patent Owner’s construction with reasonable clarity, deliberateness, and precision.

      “We find Patent Owner’s arguments unavailing. In particular, we find unavailing Patent Owner’s contention that “‘bus line 430’ is not an ‘auxiliary electrode’” (PO Resp. 28–33), because Patent Owner is relying on a claim construction of “auxiliary electrode” as precluding “essential” elements and requiring “more than the end structure of a conductor” (id.), that is not adopted by our construction discussed above. Here, we are persuaded by Petitioner’s reliance on Weaver’s bus line 430 for providing the claimed “electrode,” that is “supplemental to other electrodes in the structure.” Pet. 18; see also Ex. 1004 ¶ 26, Fig. 4; Ex. 1003 ¶ 92. We find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that a POSITA would have understood that “anode 406 and bus line 430 are connected in parallel,” which means that “bus line 430 is a supplemental electrode that reduces the total resistance of the pixel structure.” Pet. 19; Ex. 1003 ¶ 94. Thus, we find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that Weaver’s bus line 430 is an electrode supplemental to other electrodes in the structure that is electrically insulated from transistor 410 by passivation layer 409, wherein OLED 400, which includes cathode 422, organic layer 424, and anode 406, is disposed above bus line 430, and wherein anode 406 of OLED 400 is electrically connected to bus line 430 by via 428. Pet. 16–19; Ex. 1003 ¶¶ 89–94. That is, we find availing Petitioner’s contention that, like the ’509 patent’s auxiliary electrode 120, bus line 430 is electrically insulated from transistor 410, wherein OLED 400 is disposed above bus line 430 and anode 406 electrically connected with bus line 430.

      “We also find unavailing Patent Owner’s contention that the proposed modifications to Weaver would involve changing the process. PO Resp. 33– 34. We agree with Petitioner, whose contentions are supported by Dr. Baker’s testimony, that “to provide additional components from the same layer is a layout change that a POSITA would have been able to perform without changing the process.” Pet. Reply 17–18 (citing Ex 1003 ¶ 157; Ex. 1020 ¶ 45). Further, contrary to Patent Owner’s contention that POSITA would not have combined Weaver with Lee ’053, Song, Lee ’149, or Bae without the use of hindsight (PO Resp. 33–45), as Petitioner points out, Lee ’149, for example, “explicitly teaches that ‘the electrode pattern 45 serves to lower the resistance of the first electrode 41.” Pet. Reply 58 (citing Ex. 1011 ¶ 38). Similarly, Bae “explicitly teaches that the “auxiliary electrodes 139 contact the first electrode 132 to commonly apply a voltage to the sub-pixels” and “reduces the resistance of the first electrode.” Id. at 66 (citing Ex. 1012 ¶¶ 37, 59). As such, Petitioner’s proposed combinations are supported by at least by Lee ’149’s and Bae’s teachings of applying a second electrode to lower the resistance and voltage drop between anode 406 and the VDD line of Weaver. See, e.g., Ex. 1011 ¶ 38; Ex. 1012 ¶¶ 37, 59. We are persuaded by Dr. Baker’s testimony that a POSITA would have understood that higher resistance between the power or ground line to the light emitting device would consume more power and require higher operating voltages, and thus, would have been motivated to implement the solutions of Lee ’053, Song, Lee ’149, or Bae to lower the resistance between anode 406 and voltage source VDD in Weaver. Ex. 1003 ¶¶ 145, 158, 184, 203. We agree with Petitioner, supported by Dr. Baker’s testimony, that a POSITA would have had a reasonable expectation of success the combining the references as suggested, wherein such modification “involves modifications of only routine skill in the art,” which “involve known method,” and “would have yielded predictable results. Pet. 42, 48–49, 59, 67–68; Ex. 1003 ¶¶ 145, 158, 184, 203. That is, we determine that Petitioner has set forth reasoning with rational underpinning explaining why it would have been obvious to combine the teachings with a reasonable expectation of success. Based on the complete record presented, we determine Petitioner has shown by a preponderance of the evidence that claims 6–8 would have been obvious over the combination of Weaver and Lee ’053 or alternatively over the combination of Weaver and Song, and that claims 10 and 11 would have been obvious over the combination of Weaver and Lee ’149 or alternatively over the combination of Weaver and Bae.” slip op. at 33

      “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra.

As Petitioner explains, these references are in same field of endeavor—tracking users for internet advertising, and Petitioner does not propose wholesale incorporation of the system of Van Boucq into Doughty—and therefore qualify as prior art to the ’947 patent and can be combined to show obviousness. See In re Clay, 966 F.2d 656, 658 (Fed. Cir. 1992). Petitioner proposes using certain teachings from Van Boucq’s system to improve certain aspects of Doughty.

      “1. Mesh Material In the Petition, Petitioner asks that “the term ‘mesh material’” be interpreted in accordance with “a plain and ordinary usage.” Pet. 25. Per Petitioner, the “plain and ordinary” meaning of the term “mesh material” is “a woven material of open texture with spaced holes therein.” Id.

The recited “said one or more panels” corresponds to the previously recited “one or more panels of mesh material,” not panels comprising a material that was only a “mesh” prior to printing/coating.

The ’535 Patent says that “panels” of this coated mesh material 26 “are used to form” a hunting blind. Id. at 3:22–26.

Petitioner’s expert testified that it was his “understanding that Strength is silent” on “whether or not there are holes.” Ex. 2038, 44. Petitioner contends that Strength’s silence about the presence/ absence of holes hinders Patent Owner from proving that Strength’s camouflage material 10 does not have holes. See Pet. Reply 8. We agree. But this same silence likewise hinders Petitioner from proving that Strength’s camouflage material 10 does have holes.” slip op. at 35

Moreover, Petitioner’s asserted reason to combine the references is supported by the references’ disclosures: Best-2008 suggests filtration of its coolant is desirable, but provides no specific means for doing so; Osada teaches a way of filtering fluid from an open-top tank, similar to Best-2008’s.” slip op. at 42

      “We are not persuaded that this assertion supports the argument for a second petition. As argued by Patent Owner, Petitioner’s alleged need is undermined by the distribution of its arguments across the 110 IPR and this proceeding. As discussed above, for the “at least one thigh support adjusters” in the 110 IPR, Petitioner relies on one prior art structure from the first category and two prior art structures from the second category; and for the “at least one thigh support adjusters” in this proceeding, Petitioner relies on two prior art structures from the first category and one prior art structure from the second category.

In contrast, in the SolarEdge decision cited by Petitioner, the first-ranked petition presented one approach as to the prior art and the second-ranked petition was permitted because it presented a different approach, such that the two petitions “do not overlap in any meaningful way.” SolarEdge v. SMA Solar Techs., IPR2019-01224, Paper 10 at 10 (PTAB Jan. 23, 2020), cited at Expl. 4.

Looking at the distributions of the constructions presented, however, the same reasoning above applies as Petitioner relied on each construction at least twice to address the “one thigh support adjuster” in each proceeding. See 110 Petition 27 (relying on both constructions for Ground 1), 53–57 (relying on only a § 112(f) construction for Ground 2), 86–90 (relying on both constructions for Ground 3); Pet. 29–34 (relying on only a § 112(f) construction for Ground 4), 61–63 (relying on both constructions for Ground 5), 88–90 (relying on both constructions for Ground 6). description support for the ‘at least one thigh support adjuster’ limitation” (Ex. 1029 at 5) does not warrant a second petition here. The challenged patent was clearly available to Petitioner, and Petitioner was—even with Patent Owner’s non-substantive answer to the interrogatory (id. at 6)—able to propose a construction of “at least one thigh support adjuster” under § 112(f). See Pet. 7–12. For these reasons, the two different constructions presented do not warrant a second petition in this proceeding.” slip op. at 12

We do not address the anticipation challenge at this time. “Petitioner does not offer any showing on any motivation to modify Figure 9 of Haddad138 to change the configuration from a FSI to BSI architecture.” Id. at 8. On this record, Patent Owner’s argument does not undermine Petitioner’s persuasive showing. As Petitioner argues (Pet. 29), Haddad138 teaches that its “present disclosure” (which would include the Figure 9 disclosure) can be adapted for a front side illumination (FSI) or back side illumination (BSI) configuration. Ex. 1012 ¶ 48. The express teaching of Haddad138 provides motivation to modify Figure 9 of Haddad138. Patent Owner also argues that Petitioner “offers no showing that a POSITA would be able to modify the embodiment of Figure 9 to be back side illuminated with a reasonable expectation of success.” Prelim. Resp. 9. Patent Owner’s argument again does not undermine Petitioner’s persuasive showing. Petitioner cites Haddad138 expressly teaching a FSI or BSI configuration. Pet. 29 (citing Ex. 1012 ¶ 48).

Here, Fintiv factors one and five are neutral, factors two and three favor discretionary denial, factor four strongly weighs against discretionary denial, and favor six weighs against discretionary denial. The integrity of the system will benefit from institution because of the strong merits the Petition presents (factor six), and the ITC Investigation will not resolve these merits (factor four). This outweighs any potential inefficiency as indicated by factors two and three. We further note that any inefficiency in resolving the grounds the Petition presents is mitigated by the stay of the district court action (factor one).

      “After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims. As we explain in Section III(G), infra, Petitioner’s challenges to the ’227 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak. Given the strength of Petitioner’s challenges on the present record, this is not a situation where we would say that “reasonable minds can disagree regarding the purported treatment of the art,” and we therefore determine that the Examiner erred by not considering the art in substantially the combination Petitioner proposes. Where Patent Owner states that “evidence that the Examiner did not consider these references in combination” is lacking (PO Sur-Reply 5), we disagree. If the Examiner considered these references in combination, the Examiner would have, given the apparent strength of Petitioner’s position on the merits on this record, issued a rejection. The lack of a rejection based on the combination proposed in the Petition provides some evidence that the Examiner did not consider these references in combination (because the lack of such a rejection raises the likelihood that the Examiner did not make such a consideration). 3.
