“B. Patent Owner’s Disclaimer of Claims 17 and 20 As indicated above, Patent Owner filed a statutory disclaimer of claims 17 and 20 of the ’666 patent. See Ex. 2005. In view of Patent Owner’s statutory disclaimer, we treat claims 17 and 20 as having never been part of the ’666 patent. See Vectra Fitness, Inc. v. TNWK Corp., ‘considered as part of the original patent’ in [35 U.S.C.] § 253 to mean that the patent is treated as though the disclaimed claims never existed.”). Because inter partes review cannot be instituted based on disclaimed claims, we do not consider claims 17 and 20 to be within the scope of this proceeding. 37 C.F.R. § 42.107(e) (“No inter partes review will be instituted based on disclaimed claims.”); General Elec. Co. v. United Techs. Corp., IPR2017-00491, Paper 9 (PTAB July 6, 2017) (precedential) (denying institution in view of a statutory disclaimer of all the challenged claims).

“curved side surface” are premised on its proposed claim construction which, as set forth above, we decline to adopt. Instead, we determined that “curved side surface” as used in the challenged claim encompasses any outer surface of the structure with curvature, which does not need to be curved in any specific direction. See § II.B.1, supra. Kim states: Embodiments of the inventive concepts in which the protrusion pad PAD_P has a rectangular parallel[] shape is illustrated, but the protrusion pad PAD_P is not limited thereto and, in some embodiments, may have a shape including a curved surface based on a virtual rectangular parallel[] shape, a cylindrical shape, or any shape. Ex. 1005, 8:29–34 (emphases added). Dr. Lee testifies that “[a] POSITA would have recognized that this includes configurations where the sides of the protrusion pads are curved, particularly to optimize electrical connectivity and mitigate stress at material interfaces.” Ex. 1003 ¶ 201. Dr. Lee further testifies that a POSITA would have understood Kim’s disclosure “teaches a variety of different protrusion pad PAD_P shapes” including “pads with curved sides when viewed in cross-section or pads with curved sides when viewed from above.” Id. ¶ 202. Accordingly, we determine that Kim discloses a cylindrically-shaped PAD_P that has a “curved side surface” as required by the challenged claim. slip op. at 24

The package substrate 310 includes a package common ground rail 360, and the segmented SoC ground rails 350, 355 are independently connected to the package common ground rail 360 via separate connections 370, 375 respectively.”). As set forth above, Dr. Foty describes the three ground lines in Saint Figure 7-7 as “segmented rails” when discussing the combination of Saint and Haralabidis, thus equating the three ground lines in Saint Figure 7-7 with Haralabidis’ segmented ground rail. Ex. 1003 ¶ 368. Neither Petitioner nor Dr. Foty, however, adequately addresses how or why a POSITA would have understood that the three separate grounds lines in Saint Figure 7-7 were “segmented rails” like the segments of the single ground line described in Haralabidis. In contrast, Dr. Khatri credibly testifies: Haralabidis teaches the use of a “common ground rail” to connect “segmented ground rails.” Haralabidis, 3:9–22, 3:34– 40, 3:65–4:12. A POSITA would understand “segmented ground rails” to refer to a single ground signal that has been “segmented.” That is fundamentally different from the design of Saint’s Figure 7-7 that Dr. Foty relies on, which uses three different ground signals, GND1, GND2, and GND3—not a single ground signal that has been “segmented.” Because of that, a POSITA would not have been motivated to change the Figure 7-7 design completely to connect three separate signals (GND1, GND2, and GND3) together as Dr. Foty proposes. Ex. 1003 ¶ 368. Indeed, for these reasons, a POSITA would have understood Haralabidis’ teachings of a “common ground rail” are inapplicable to Saint’s Figure 7-7. Ex. 2010 ¶ 129. Petitioner’s arguments and Dr. Foty’s testimony with respect to the modification of Saint Figure 7-7 leave an analytical gap that does not apprise us of why a POSITA would have modified Saint Figure 7-7 to include a common ESD bus as described in Haralabidis.” slip op. at 37

“For these reasons, we find that Yoshinaga’s statement that “[r]eference potential pads are not shown to simplify the drawing” indicates that reference potential pads are not depicted in Yoshinaga Figure 6, and determine that Yoshinaga Figure 6 does not disclose “a plurality of pad groups, adjacent and connected to the plurality of ESD buses” as recited in claim 6. Petitioner also argues that a POSITA would have understood that power supply pads 3, 4, and 58 in Yoshinaga “could just as readily be used as reference pads” and it would have been obvious “to use the pads immediately next to the saved areas as reference pads (e.g., pads 5 and 6) as pad assignments were left to the designer’s discretion.” Pet. 31 (citing Ex. 1003 ¶¶ 137–139). Petitioner asserts that “selecting which pads to use for ground, power signals, etc. is a design choice that depends on factors like chip size, the number of I/O signals, and the number of pads available.” Pet. 31 (citing Ex. 1003 ¶ 137–139). Petitioner states that such discretion would be to preserve Yoshinaga’s saved area for other circuitry as taught by Saint. Pet. 31–32 (citing Ex. 1003 ¶¶ 137–139; Pet. 19–23 (§ IX.A)). Neither Petitioner nor Dr. Foty adequately explain, however, why a POSITA would have made this specific design choice, namely, replacing power supply pads 3, 4, and 58 with reference pads. Pet. 31; Ex. 1003 ¶¶ 137–139; see also Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1069 n.4 (Fed.

Cir. 2016))). Petitioner offers the general proposition that pad assignments are left to the designer’s discretion, but this does not provide a reason why a POSITA would have been motivated to modify Yoshinaga Figure 6 as proposed. Pet. 31; Ex. 1003 ¶¶ 137–139. We have determined that Yoshinaga does not show (rather than does not label) reference pads. Because all of Yoshinaga’s illustrated pads are power supply pads, Petitioner’s proposed reassignment of pads would not be a simple matter of rearrangement of an existing mixture of power supply and reference pads, but require that reference pads be imported from elsewhere, and power supply pads be moved to some unspecified location. Petitioner’s arguments and Dr. Foty’s testimony with respect to the modification of Yoshinaga Figure 6 leave an analytical gap that does not apprise us of why a POSITA would have modified Yoshinaga Figure 6 to include reference pads in the place of power supply pads 3, 4, and 58.

“Based on the record before us, we agree with Petitioner that “on a surface” should be interpreted in line with the definition of “on” set forth in the ’711 patent. Ex. 1001, 4:1–6. We particularly note that the ’711 patent states that “‘on’ . . . should be interpreted in the broadest manner” and that “on” is not limited to “directly on.” Id. Instead, the ’711 patent states that “‘on’ also includes the meaning of ‘on’ something with an intermediate feature or layer therebetween.” Id. Patent Owner agrees that this definition controls the “standalone ‘on’” term such that A may be on B even if there is an intervening layer between them. Tr. 55:8–11 (“The standalone ‘on,’ we agree in the context of the patent, you can have intervening layers. I think the patent is clear about that.”). Claim 14 recites that the etch-stop layer is “on” something; i.e., “on a side surface and a top surface of each step.” Ex. 1001, 16:20–22. Patent Owner agrees that a surface is a “something.” Tr. 56:5–8 (“surface obviously is a something”). Substituting the “a “‘on’ something with an intermediate feature or layer therebetween” results in claim 14 reading as, “on a surface with an intermediate feature or layer therebetween.” Unlike “directly on,” which specifies the relation between two things, “a surface” may merely indicate the thing that something is “on,” particularly when “on” is “interpreted in the broadest manner” as expressly required by the ’711 patent.” slip op. at 7

“Although Dr. Campbell testified in his deposition in response to Petitioner’s counsel that “on the surface” requires direct contact with the surface, his interpretation was based on “embodiments of” the patent rather than a general understanding of a person skilled in the art confronted with that term. Ex. 1027, 122:6–25, 124:6–23 (“I’m not sure if there are other sources for that, but it was on the ’711, so I’ve taken it there.”). Dr. Campbell, upon questioning from Patent Owner’s counsel, later stated that “an expert in semiconductor fabrication” would understand “on the surface” to mean “contact between one layer and another . . . with nothing in between.” Id. at 146:25–147:6. However, Dr. Campbell did not explain why such an interpretation is particular to the semiconductor fabrication art, or provide other explanation or support for this statement, which is in tension with the definition of “on” in the ’711 patent. Accordingly, we significantly discount the weight accorded to that statement. Phillips, 415 F.3d at 1318 (stating, “conclusory, unsupported assertions by experts as to the definition of a claim term are not useful to a court. Similarly, a court should discount any expert testimony ‘that is clearly at odds with the claim construction mandated by the claims themselves, the written description, and patent.’”). On balance, Dr. Campbell’s testimony is best understood as a description of certain Figures of the ’711 patent rather than a representation of an ordinarily skilled person’s understanding of the term “on the surface.” See Ex. 2009 ¶ 47 (describing Figs. 1, 3, and 4 as depicting layers in contact with the underlying layer or substrate). For example, Dr. Campbell describes Figure 9A as having a barrier layer “on and directly contacting the top and side surfaces of each step.” Id. ¶ 28 (emphasis added) (citing inter alia Ex. 1001, 7:6–67). Dr. Campbell does not explain why, beyond the fact that many Figures show layers as adjacent and in contact, a person of ordinary skill in the relevant art would understand those Figures to limit the claim language rather than illustrating particular embodiments that fall within a broader scope of claims 14 and 15. See Hill-Rom Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed.

“We agree with Petitioner that Kim’s first and second section are described as compatible, not mutually exclusive, embodiments.

Ex. 1005 ¶ 184 (emphasis added). Patent Owner argues that only the embodiments in Figures 17A–22B describe an etch-stop layer and a barrier layer (as claimed), and that the language cited for a gate-stack-on-top configuration (e.g., Ex. 1005 ¶¶ 90, 91, and 240) is “conspicuously absent from the description of Figures 17A–22B.” PO Resp. 20 (citing Ex. 2009 ¶ 36). However, Figures 17A–22B do not further address the underlying staircase structure that was detailed in the descriptions of the Figures 4 through 15 embodiments. While Figures 17A–22B show a gate-stack-on-bottom configuration, this merely continues the gate-stack-on-bottom illustrations that were used in all of the previous Figures, even for those in which it is undisputed that a gate-stack-on-top configuration is a described alternative.

The plain language of claim 1 does not address additional properties of the perforated polymeric layer; the language of the dependent claims, however, imposes additional limitations on the properties of the perforated polymeric layer such as a particular basis weight (claim 2), a particular makeup (claim 3), a particular aperture size (claim 7), a particular open area (claim 8), and that it “is a three-dimensionally formed layer having penetrating apertures extending from a first surface of the first perforated polymeric layer towards a second surface of the first perforated polymeric layer and forming protrusions on said second surface” (claim 4).

“layer pierced through with holes or apertures,” we are persuaded that Petitioner meets its burden as to this limitation. Petitioner argues that under our construction, Bergstrom’s express disclosure of forming element 60, and Bergstrom’s explanation of the properties of forming element 60, meets the claimed “perforated polymeric layer” limitation. Pet. 38–41 (citing Ex. 1002 ¶¶ 114–117). Even under Patent Owner’s proposed construction, Petitioner argues, forming element 60 would also allow free flow of liquid bodily waste. Pet. Reply 3– 4 (citing Ex. 1021 ¶¶ 20–23). Importantly, Bergstrom expressly discloses: “suitable materials for the forming element 60 are plastic films, perforated plastic films and reinforced tissue or reinforced nonwoven materials.” Ex. 1004, 10:1–4. This express disclosure is clear. Even though the forming element 60 in Bergstrom might be “typically” liquid-impermeable (Ex. 1004, 9:24–30), that does not preclude a layer that is perforated, particularly where Bergstrom expressly discloses a perforated plastic film as one of the possibilities for forming element 60. Ex. 1004, 10:1–4. Additionally, although Patent Owner focuses on Bergstrom’s disclosure that forming element 60 is “typically liquid-impermeable” (PO Resp. 58–60; Ex. 1004, 9:24–30), we do not view Bergstrom’s use of the word “typically” as mandating that the forming element always be liquid impermeable. We agree that the word “typically” does not mean “always” and that such a reading would render “typically” superfluous. Pet. Reply. 5. We do not find any ambiguity in Bergstrom’s disclosure regarding possible use of perforated plastic films for its forming element 60; whether or not the forming element 60 provides other functions (like stiffness) does not dictate whether it may also be perforated, or be part of a fluid flow control structure. On this point, we credit Petitioner’s arguments and explanation, as supported by Dr. Pourdeyhimi’s testimony. Pet.

“from the start” (PO Resp. 29), and that “using all or part of [Glaug’s] fluid-acquisition system in place of [Nakazawa’s] diffusion sheet would be antithetical to the teachings of both references” (id. at 35), we agree that the proposed combination of Nakazawa’s structure with the layers of Glaug is sufficiently motivated and reasonably expected to result in a successful article, for the reasons articulated by Petitioner. See, e.g., Pet. 59–65; Ex. 1002 ¶¶ 176–192. Namely, although fluid may flow in both Z directions in Nakazawa (PO Resp. 30), that does not foreclose the combination with Glaug in the manner proposed by Petitioner. See generally Ex. 1002 ¶¶ 176–192; see id. ¶ 184 (detailing the mechanics of the proposed combinations), ¶¶ 188–191 (discussing motivation to combine), ¶ 192 (discussing reasonable expectation of success). The combination can be achieved “either by adding the lower acquisition layer 64 [of Glaug] to diffusion sheet 63 [of Nakazawa], or by replacing diffusion sheet 63 [of Nakazawa] with the two-layer fluid acquisition system 34 [of Glaug],” and as persuasively explained by Dr. Pourdeyhimi, the arrangement constitutes a “fluid flow control structure.” See Ex. 1021 ¶¶ 45–47. Additionally, the diffusion sheet in Nakazawa can be made from the same material as used in Glaug, namely, AquiDry™. Id. ¶¶ 53–55; see also Tr. 17:25–18:3 (“although Glaug does not specify the name AquiDry in its disclosure, Patent Owner’s expert testified that it’s his understanding that Glaug is discussing the AquiDry material, the same material that is in Nakazawa . . . . they disclose using the same material, and Nakazawa says this material work[s]”). When asked if Patent Owner’s expert had any concerns that AquiDry was not the same as between Nakazawa and Glaug, Patent Owner’s counsel replied “They are the same, Your Honor. And we embrace that.” Tr. 46:8–12; see also id. at 58:19 (Petitioner’s counsel commenting about Patent Owner’s counsel: “they agree, AquiDry is used in both Nakazawa and Glaug”). Thus, Patent Owner’s argument that Nakazawa’s diffusion sheet and Glaug’s fluid acquisition layer have different purposes because Nakazawa’s diffusion sheet allegedly must promote fluid flow in the Z-directions, both toward and away from the body (PO Resp. 29–37; Ex. 2004 ¶¶ 26–28, 30– 35)) is not clearly supported by Nakazawa, and is also contravened by the shared disclosure of Nakazawa and Glaug as to the composition of the disputed layer. We have reviewed the complete record, including Patent Owner’s and Mr. Sheldon’s assertions that Nakazawa requires promoting fluid flow in both Z-directions (see id.), but find that Petitioner carries its burden to demonstrate that one of ordinary skill in the art would have been motivated to combine Nakazawa and Glaug with a reasonable expectation of success. On this complete record, Petitioner explains sufficiently why and how a person of ordinary skill would modify Nakazawa’s diffusion sheet, i.e., to use Glaug’s fluid acquisition system, or the lower non-perforated layer of its fluid acquisition system, in Nakazawa, and Petitioner provides well-supported reasons for doing so.” slip op. at 36

Accordingly, we determine that the ordinary and customary meaning of “movement vector” is “a vector indicating movement of an object.” 3) “operation indicator” Petitioner” slip op. at 20

“Dr. Kanellakopoulos’s explanation that angular momentum is not inherent to an object, and its computation requires an arbitrary choice of a point of origin that has no physical meaning in the context of vehicle motion, also supports Patent Owner’s position. Id. ¶ 71 (citing Ex. 2004, 262). Accordingly, Patent Owner’s argument, that angular momentum cannot be used to detect a vehicle turning, is persuasive. Id. We also find persuasive, as Dr. Kanellakopoulos explains, that Petitioner’s argument regarding the figure on Kleppner 234 is based on misinterpretation of the vectors in that figure. Id. ¶ 67 (explaining that Kleppner 233–234 does not depict a gravity vector).” slip op. at 35

“Kleppner does not disclose a rotation vector, a person of ordinary skill would have used the knowledge of a rotation vector (because it is a term of art) alongside Kleppner’s teaching, to arrive at claim 1. See Pet. Reply 11. This argument does not satisfy Petitioner’s burden to provide articulated reasoning with some rational underpinning to support the conclusion of obviousness. See KSR, 550 U.S. at 419 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Petitioner does not explain which teaching of Kleppner a person of ordinary skill would have selected and combined with their knowledge of a rotation vector to yield the method of claim 1, or explain why a person of ordinary skill would have recognized based on Kleppner that estimating the angle between a rotation vector and gravity vector could be used to detect a vehicle turning. Nor does Petitioner respond to Patent Owner’s assertion that Kleppner provides no rationale for estimating an angle of alignment between a rotation vector and gravity vector as a way of detecting a vehicle turning. See Ex. 2001 ¶ 65.” slip op. at 35

“A party may request judgment against itself at any time during a proceeding. 37 C.F.R. § 42.73(b). Under the Rules, actions construed as a request for entry of adverse judgment include “[c]ancellation or disclaimer of a claim such that the party has no remaining claim in the trial.” 37 C.F.R. § 42.73(b)(2). Here, Patent Owner has disclaimed, under 37 C.F.R. § 1.321, claims 1–42 of the ’407 patent, which constitute all challenged claims involved in this trial. See Ex. 2031. We thus construe the statutory disclaimer as a request for entry of adverse judgment. Having reviewed the statutory disclaimer, we determine that adverse judgment against Patent Owner with respect to claims 1–42 of the ’407 patent is appropriate.” slip op. at 2
