“Relying on the testimony of Patent Owner’s declarant Dr. Singhose, Petitioner argues that a person of ordinary skill in the art “would have known a central straight path has less airflow resistance than a circuitous one.” Reply 22–23 (citing Ex. 1035, 127:15–128:9). But the same witness also testified that higher airflow resistance might be desirable and explained that providing more resistance to airflow might result in improved mixing. Ex. 1035, 21:21–22:12, 127:20–24, 170:10–14. In addition, Dr. Singhose testifies that the complicated design of the airflow passageway in Xia “serves important functions,” including “allow[ing] large droplets to be reabsorbed by the liquid-guiding mechanism,” allowing “excessive liquid in the airflow [to] condense,” and “prevent[ing] the chemical liquid from being sucked into the mouth.” Ex. 2022 ¶ 183 (citing Ex. 1004, 11, 13–14, 16). Although Petitioner’s declarant Dr. Sturges testifies that a straight airflow passageway “would provide improved, smoother air flow,” he does not provide any evidence supporting the view that the air flow would be improved. Ex. 1007 ¶ 118. We credit the testimony of Dr. Singhose that using a straight passageway in Xia would have been detrimental rather than beneficial. Ex. 2022 ¶ 183. Petitioner also argues that the inventors’ use of a straight path is evidence that the use of a straight passageway was “merely common-sense obviousness.” Reply 22–23. This is hindsight. Otsuka Pharm. Co. v. Sandoz, Inc., 678 F.3d 1280, 1296 (Fed. Cir. 2012) (“The inventor’s own path itself never leads to a conclusion of obviousness; that is hindsight.”). Moreover, it does not address the testimony of Dr. Singhose that the use of a complicated passageway like that in Xia had benefits not present in a straight central passageway.” slip op. at 29

“Patent Owner argues, however, that this presumption is overcome in the present case, and we agree. PO Resp. 28–32. We note that, although the claims require the first aperture to be “on the first end,” the claims still require that the “housing hav[e] a first aperture.” Thus, the issue is whether the aperture must be on the housing itself or part of the housing, as well as whether the aperture is on the first end of the housing. Although “having” and “includes” are used with respect to the solution holding medium to refer to elements located inside the housing, the specification of the ’881 patent suggests that the ends of the housing are part of the housing itself, rather than located inside the housing. First, “the first end . . . can be integrated into a single assembly as part of the housing.” Ex. 1001, 6:16–17. Second, “the housing . . . may comprise the cylindrical wall and two end-caps,” or “the housing . . . may comprise the cartridge wall and a single end-cap.” Id. at 3:55–59. The only figures of the ’881 patent that depict first end 206 show it at the end of the housing rather than located within the interior of housing 202. Id. at Figs. 2, 3. Moreover, there is no requirement to construe a claim term uniformly across multiple uses in the claims when doing so would be nonsensical. Microprocessor Enhancement Corp. v. Texas Instruments, Inc., 520 F.3d 1367, 1375 (Fed. Cir. 2008). Here, construing a first element that is recited as “having” or “includ[ing]” a second element always as encompassing not only second elements that are part of the first element, but also second elements that are located within the interior of the first element, would lead to nonsensical results. Claim 2 recites an airflow passageway “having a length having a circular cross section.” Ex. 1001, 17:59–60. It would be nonsensical to interpret this claim as encompassing an airflow passageway of non-circular cross section that contains another object that has a circular cross section, and neither party argues in favor of such a reading. Similarly, claim 16 recites an “airflow passageway having an interior having a uniform cross-sectional area,” and there is no reason to interpret this claim as encompassing an airflow passageway of non-uniform cross-sectional area that contains another object that itself has uniform cross-sectional area. Id. at 19:47–48. Thus, the claims do not use “having” or “includes” consistently to refer to elements located within the interior of an object; instead, they sometimes use these terms to refer to elements that are a part of an object. See Epcon Gas Sys., Inc. v. Bauer Compressors, Inc., 279 F.3d 1022, 1030–31 (Fed. Cir. 2002) (terms should be construed based on the context of how the terms are used in the claims).” slip op. at 13

“We agree that Petitioner has not shown that a person having ordinary skill in the art at the critical time would have been motivated to replace the wordlines in the staircase region with dielectric material if the result is that one of the memory cell arrays becomes unavailable. Petitioner relies upon two usable arrays for its combination, emphasizing Thimmegowda as desirably enabling “a single conductive contact (e.g., 334a) to bidirectionally drive memory cells in the memory arrays on either side of the bridge”; i.e., both the left and right memory cell blocks.

Petitioner and Dr. Banerjee rely upon the motivation of reducing punch-through, because punch-through causes “yield loss”; i.e., loss of the usability of the wordlines connected by the punch-through. Ex. 1003 ¶ 103; Pet. 35. However, such advantage is premised on retaining both arrays, and neither Petitioner nor Dr. Banerjee explains how the advantages of reducing punch-through should be weighed against a disadvantage of losing access to one of the two arrays. Nor do Petitioner and Dr. Banerjee discuss how the advantages of metal gate replacement should be weighed against losing access to one of the two arrays.4 Patent Owner’s declarant, Dr. Giapis, attests to the undesirability of such a combination, in which one array 4 Additionally, the claims of the ’604 patent do not require a metal conductor portion; Petitioner does not explain why gate replacement to a metal conductor from a polysilicon conductor, described as used in Lee’s “memory device at large,” (Pet. 40) is a benefit associated with Lee’s finger teaching relevant to the claims. Ex. 2007 ¶¶ 50–54. We agree with Patent Owner that the advantage of preventing individual wordlines from becoming unusable because of punchthrough would be outweighed by the loss of half of the wordlines if one of the memory arrays were to become unavailable because its connections were removed.” slip op. at 15

“trial allays concerns about inefficiency and duplication of efforts.” Fintiv, 6. However, when there is a parallel district court litigation and an ITC investigation, “district court litigation is often stayed under 28 U.S.C. § 1659 pending resolution of the ITC investigation.” Id. at 7.

“determined that the combinations of Seo or Nam with Choi were not persuasive. Dec. 14–15, 19–20. For example, we determined that “Dr. Liu’s statement that ‘[a] POSITA would have recognized that the lateral-electrical-field-inducing voltage differential, as Seo discloses, is what Choi describes as driving the lateral fast-charge loss,’ is not supported by objective evidence or sufficient explanation as to why a POSITA would have come to that understanding” and was therefore insufficient to support Petitioner’s asserted motivation to combine Seo with Choi. Id. at 14–15. In particular, we were not persuaded that “Seo creates a large lateral electric field like the one described in Choi,” and, in any case, we disagreed that “Choi teaches that a large lateral electric field removes fast charges.” Id. at 15. Accordingly, regardless of the duration of the voltage application described in Seo, Petitioner failed to show that the combination of Seo and Choi would result in removal of fast charges. We further determined that Petitioner’s combination of Nam with Choi was problematic for similar reasons, given Petitioner’s reliance on similar arguments. See id. at 20.” slip op. at 10

“the knowledge of one of ordinary skill in the art relating to charge-trap memory devices demonstrates fast charge removal. See Pet. 36, 81–82. And although Petitioner cites its declarant, Dr. Liu, for the proposition that “Seo discloses, and would have been understood to disclose, performing its read operation on charge-trap memories, which removes fast charges,” Dr. Liu does not cite objective evidence to support this assertion, aside from the ’342 patent itself. Id. at 36 (citing Ex. 1003 ¶ 136). Moreover, Dr. Liu’s testimony simply circles back to logic similar to that relied on with respect to the inherency theory, namely that, given certain similarities between Seo and the ’342 patent, Seo removes fast charges because the ’342 patent teaches removing fast charges, even though Seo does not explicitly teach doing so. See Ex. 1003 ¶ 136 (“[A] POSITA would have immediately understood from reading Seo that Seo is disclosing its read operation as applicable to Flash memories, including Flash charge-trap memories. And as the ’342 states, Seo’s operation would remove fast charges in a charge-trap memory.” (citing Ex. 1001, Abstract)). As already discussed, we disagree with this logic based on the lack of sufficient evidence to support its conclusion. See Dec. 13 (“Petitioner and Dr. Liu do not provide any objective evidence or explanation as to how or why a POSITA would have understood that Seo’s voltage amounts applied during Seo’s time periods operate the same way [as in the ’342 patent] on Seo’s memory device to generate fields with sufficient magnitude and duration to remove fast charges.”). Petitioner’s assertions regarding Nam suffer from the same shortcomings. See Dec. 19–20; Pet 82 (“[A] POSITA would have found that Nam’s teachings are applicable to charge-trap devices”); Ex. 1003 ¶¶ 293–298.” slip op. at 8

“dummy source structure might not even be an inoperable structure,” and therefore “the ’872 Patent does not use ‘dummy’ to exclude the dummy source structure from being an operable, functioning element.” Ex. 1003 ¶ 85 (citing Ex. 1001, 5:41–43, 16:63–66). In support of his testimony, Dr. Banerjee points to the Specification’s teaching that “[i]n some embodiments, one or more dummy source structures are in contact with the substrate and may provide interconnect between the 3D memory device and peripheral devices” (Ex. 1001, 5:41–43), and “[w]hen conductive materials are used to fill dummy source hole 212 (e.g., contact 224), the dummy source structure 246 may function as an interconnect to connect 3D memory device 100 with other peripheral devices” (id. at 16:63–66), which we considered and relied upon in construing “dummy source structure” in the Decision. Dec. 11–13. None of the functions identified by Dr. Banerjee, however, relate to whether the dummy source structure would function as a source to the memory cells. Specification consistently describes that function as an interconnect with other peripheral devices, and does not teach or suggest that the dummy source structure may function to provide source to the memory cells. See Ex. 1001, 5:40–43 (“In some embodiments, one or more dummy source structures are in contact with the substrate and may provide interconnect between the 3D memory device and peripheral devices.”), 11:46–48 (“In some embodiments, dummy source structures 178 may function as interconnects to connect 3D memory device 100 with other peripheral devices.”), 16:63–66 (“When conductive materials are used to fill dummy source hole 212 (e.g., contact 244), the dummy source structure 246 may function as an interconnect to connect 3D memory device 100 with other peripheral devices.”). Our construction of “dummy source structure” is consistent with the Specification, and does not foreclose the dummy source structure from being operational, for example, as an interconnect to peripheral devices. Nor is it inconsistent with the Specification’s teaching that “[i]n some embodiments, dummy source structure 246 may not connect to channel structures in the inner region.” See Req. 11 (citing Ex. 1001, 16:38–44). In the case where the dummy source structure connects with the channel structures, the other end may connect with peripheral devices, or may be a dead end. Thus, even if the dummy source structure is operable as an interconnect to connect the 3D memory device with other peripheral devices, it does not follow that a dummy source structure would function as an interconnect to a supply that provides source to the memory cells. For these reasons, we are not persuaded that we abused our discretion in our construction of the term “dummy source structure.”” slip op. at 5

“These deficiencies in analysis raise the question of whether the Petition adequately identifies the number of actual challenges, and evidence supporting each, with the degree of particularity required of petitions in our forum. The Petition does not explain why so many grounds are necessary under the circumstances or why the Board should impose on Patent Owner the burden of defending against so many challenges. See generally Pet. An inter partes review based on 24 distinct grounds raised against a single claim, supported by analysis lacking in particularity, potentially burdens Patent Owner unduly and makes inefficient use of the Board’s resources.

“A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A. Thus, for these additional reasons, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over Saxler, Beach, and Shenoy.” slip op. at 34

“remove the recess in Saxler Figure 1A to arrive at the allegedly enhancement mode transistor of Modified Figure 1A. Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68. Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A. Pet. 25, 40, 45. For example, Petitioner asserts that Saxler’s gate contact may be “recessed or non-recessed” and that when the gate recess shown in Figure 1A is not utilized, Saxler would have the structure of Saxler Modified Figure 1A.
