Pet. 4 (citing Ex. 1002 ¶¶ 40–42). Patent Owner adopts Petitioner’s definition of a person of ordinary skill in the art. PO Resp. 6. Considering the subject matter of the ’974 patent, the background technical field, and the asserted prior art, we agree with Petitioner’s proposed qualifications for the person of ordinary skill in the art, except we decline to adopt “at least,” as that language is vague and open-ended. Otherwise, Petitioner’s proposed definition is consistent with the level of skill reflected in the specification of the ’974 patent and the asserted prior art references. See Okajima v.

Pet. 11–12. First, the plain language of the claim does not require merely a “layer” having a plurality of vertically oriented semiconductor memory cells, but rather “a stackable add-on layer” having a plurality of vertically oriented semiconductor memory cells; that plurality is bonded to the dielectric layer. Ex. 1001, 12:29–32. A construction that gives meaning to all words of the claim is preferred. Merck & Co., Inc. v. Teva Pharm. USA, Inc., 395 F.3d 1364, 1372 (Fed.

      “We agree with Patent Owner that Petitioner has not demonstrated that Aspar would improve Lee, would solve a problem in Lee, and that Petitioner is proposing to use Aspar in a way that is not disclosed in the reference. PO Resp. 49–50 (citing Ex. 2029 ¶¶ 153–162); Tr. 57:24–58:12; Pet. 61; KSR, 550 U.S. at 417 (asking whether a technique “would improve similar devices in the same way”), 420 (asking whether there was a known problem in the art), 421 (asking whether one of ordinary skill in the art had reason to “pursue the known options”); Intel, 61 F.4th at 1381 (explaining that obviousness may be demonstrated by showing that there was a known problem in the art (“cache coherency in multiprocessor systems”) and that a person of ordinary skill in the art would recognize that that the prior art solution to this problem (“global segmented secondary cache”) would improve the system of another prior art reference). Petitioner does not persuasively show that there was any known problem in the art with respect to Lee or its monolithic method of constructing memory arrays. Nor does Petitioner provide persuasive argument or evidence that Aspar’s wafer bonding would improve Lee’s memory device.10 For example, Petitioner states in a conclusory fashion that Aspar would address the known problem of “fabricating 3D structures,” but does not explain what those problems were or why Lee fails to solve them. Pet. 61. Dr. Sechen’s testimony merely parrots the Petition, providing no further analysis or explanation of what problem might exist in Lee when fabricating its 3D structures. Ex. 1003 ¶ 212. The Petition notes that Aspar transfers “thin layers of very good thickness homogeneity and with a high crystalline quality,” but the Petition never asserts that Lee’s direct deposition method fails to provide these same or similar qualities.

      “As discussed above, we construe “stackable add-on layer” to not include memory cells that are formed by sequential deposition on or above a substrate without being added to a separately formed substrate. It is undisputed, and indeed it is Petitioner’s assertion, that Lee’s memory devices are formed by sequential deposition. See Pet. 52 (asserting that in Lee “the layers of the array are directly deposited on the layers of each underlying level, and the array is deposited on the interlayer insulating layer formed over a substrate”); see also id. at 70 (“Lee discloses forming vertical memory devices through layer-by-layer sequential deposition on the substrate . . . .”). Therefore, Petitioner does not show that Lee discloses every limitation of independent claim 13 under our claim construction. Thus, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious in view of Lee. 3. Claims 14 and 15 Claims 14 and 15 depend from claim 13. Ex. 1001, 12:35–42. Petitioner’s arguments for these claims do not remedy the deficiencies noted above with respect to independent claim 13. Pet. 54–59. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claims 14 and 15 would have been obvious in view of Lee alone. E. Claims 16 and 17 over Lee and Endoh Petitioner contends the subject matter of claims 16 and 17 would have been obvious over the combined disclosures of Lee and Endoh. Pet. 59–69. Petitioner’s arguments with respect to these claims, however, do not remedy the deficiencies noted above with respect to Lee and its monolithic, sequentially deposited memory array.

      “combined Lee and Watanabe to achieve improved integration density. Pet. 71. Petitioner concedes, however, that the benefits of Lee’s design related to 3-D integration and improved integration density would be obtained if Lee’s memory structures are formed using either Lee’s monolithic construction method or Watanabe’s alternative stacking method. Pet. Reply 13–14 (citing Ex. 1041 ¶ 34). Thus, we are not persuaded that improved integration density provides a sufficient rationale for Petitioner’s combination of Lee’s memory device and Watanabe’s stacking method. Petitioner argues that Watanabe’s stacking method “improves the accuracy of the wiring” because the wiring is made “for each planar member.” Pet. 72 (citing Ex. 1005, 6:1–3). Watanabe also states that its disclosed methods provide “a low interconnection wire resistance.” Ex. 1005, 6:20–23. Petitioner does not, however, explain sufficiently how Watanabe’s stacking method would improve Lee’s device. For example, Petitioner does not address whether the alleged wiring benefit already existed in Lee’s monolithic array or explain how this benefit would also apply to Lee’s particular memory array, which differs in construction and elements from Watanabe’s device. This diminishes Petitioner’s benefits-based motivation to combine arguments. In general, a petitioner need not demonstrate that a particular alternate method would improve a prior art device in order to show a motivation to combine. Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023); see Pet. Reply 20 (citing Intel). But here, Petitioner affirmatively invokes improvement of Lee’s device as a reason for the combination, and we must evaluate Petitioner’s contention. Moreover, any relative lack of improvement or benefits must be weighed against any problems the alternative method would introduce. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 795–96 (Fed. Cir. 2021) (noting that simultaneous advantages and disadvantages to a proposed combination must be analyzed to determine whether the disadvantages “outweighed any reason to combine”). Here, as discussed above in more detail with respect to the ground based on Watanabe, the evidence shows that one of ordinary skill in the art would have expected Watanabe’s bonding temperature of 900– 1000° C to damage the electronic devices in an underlying substrate. Ex. 2029 ¶¶ 75–76; Ex. 2028, 123:13–124:7; Ex. 2027, 715. The expected damage to Lee’s device, when balanced against the limited evidence of a benefit to the combination,7 outweighs the reason to combine Lee and Watanabe set forth in the Petition. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious over Lee and Watanabe. 2. Analysis – Claims 14 and 15 Claims 14 and 15 both depend directly from independent claim 13. Ex. 1001, 12:35–42. Petitioner’s arguments with respect to claims 14 and 15 do not remedy the deficiencies noted above with respect to independent claim 13. Pet. 73. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that these claims would have been obvious over Lee and Watanabe.” slip op. at 40

      “We credit the testimony of Dr. Przybylski that one of ordinary skill in the art would have understood that Watanabe’s stacked structure would be severely impacted if bonded at a temperature above 900° C, as disclosed in Watanabe. Ex. 2029 ¶¶ 76–77. Dr. Przybylski’s opinion is supported by Dr. Lee’s testimony (Ex. 2028, 123:13–124:7, 125:6–126:7), as well as Watanabe (Ex. 1005, 6:6–14) and Batude (Ex. 2027, 715). As further discussed below, we find that Petitioner has not rebutted Patent Owner’s showing of nonenablement, and Patent Owner has carried its burden to demonstrate that Watanabe was not enabled for bonding temperatures of 900–1000° C, as of the 2004 filing date of the ’702 patent.” slip op. at 32

      “Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). In response, Patent Owner argues that Petitioner’s obviousness analysis is flawed because “there is no articulated reasoning regarding what specific element of claim 45 Buibas . . . does not disclose.” Prelim. Resp. 19–20. In other words, according to Patent Owner, Petitioner “failed to perform a proper obviousness analysis because Petitioner has failed to identify anything in the claims that Buibas lacks disclosure of for Ground 1A.” Id. at 20. Based on the present record, we determine that Petitioner has set forth sufficient reasoning to support a motivation to combine Buibas and Sinyavskiy for purposes of institution, as well as sufficient reasoning to support the conclusion that one of ordinary skill would have had a reasonable expectation of success in making the combination. We do not agree with Patent Owner’s argument that Petitioner’s obviousness analysis is flawed because it fails to identify what is lacking in Buibas’s disclosure. To the contrary, Petitioner explains that Buibas “broadly suggests” that its spiking neural networks “can be partitioned into modules for different tasks or behaviors” but “discloses little detail about the partitioning,” and that Sinyavskiy’s more detailed disclosure of partitioning spiking neural networks would fill in these details. See Pet. 12–13, 14–15, 24. Petitioner also relies on Sinyavskiy’s more detailed disclosures concerning partitioning the network to satisfy limitations [45.1] and [45.6]. Id. at 23–27, 35. Thus, Petitioner has sufficiently identified what is missing in Buibas (a detailed disclosure of partitioning spiking neural networks) and how that missing information is provided by Sinyavskiy (by disclosure of specific techniques for partitioning spiking networks).” slip op. at 13

      “3. Analysis At this stage of the proceeding, we determine that Patent Owner’s statements made during prosecution of the ’195 patent appear to contradict its arguments in the present proceeding. See generally Prelim. Resp. Based on the present record, Patent Owner’s statements during prosecution support Petitioner’s argument tthat a graded dopant concentration is enough to teach aiding carrier movement in a particular direction. Patent Owner does not dispute that Kawagoe has a graded dopant concentration in the active region at this stage of the proceeding. Id. Patent Owner also does not dispute that Kawagoe’s transistor has carriers in the active region or that the graded dopant concentration of Kawagoe is lowered from the surface to the bottom substrate (Ex. 1007, Fig. 17). Id. At this stage of the proceeding, the evidence of record supports Petitioner’s position sufficiently to meet the reasonable likelihood threshold for institution. We decline to make further determinations, on this preliminary record, regarding the dispute surrounding this limitation, because the trial in the 00001IPR is the better proceeding in which to do so. Specifically, as compared to the preliminary phase of this case, the instituted trial in the 10 The examined claims of the ’195 patent generally recited “a unidirectional drift field drawing all minority carriers from said surface layer to said substrate.” Ex. 1016, 286. Patent Owner amended the claims of the ’195 patent to recite “maintain[ing] a single static unidirectional electric drift field to aid the movement of minority carriers from said surface layer to said substrate.” Id. 00001IPR affords the parties a better opportunity to fully and fairly brief, argue, and develop evidence in support of their positions.

We decline to resolve the material issue of fact surrounding this limitation on this preliminary record, because the trial in the Cirrus IPR is the better proceeding in which to do so. Specifically, as compared to the preliminary phase of this case, the instituted trial in the Cirrus IPR affords the parties a better opportunity to fully and fairly brief, argue, and develop evidence in support of their positions, and, in particular, to address Cirrus Logic’s alleged admission that the existence of a gradient alone is insufficient to disclose the “aid carrier movement” limitations of independent claims 1 and 21. We observe only that, on this record, the disputed issue of material fact is not sufficient to undermine the sufficiency of Petitioner’s evidence supporting institution of review.” slip op. at 16

      “instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities.

      “Regarding the “first static unidirectional electric drift field to aid the movement of minority carriers” limitation, Petitioner relies on the parent file history and cited references, arguing that “Payne’s downward-sloping graded-dopant concentration aids the movement of minority carriers from the surface layer to the substrate to the same extent to which Applicant relied on the prior art and admitted to the Patent Office that such carrier movement would occur under the same scenario.” Pet. 23. Petitioner also asserts that the direction in which carriers are forced with the concentration profile disclosed in Payne is downward, toward the substrate and away from the surface. Pet. 23–28 (quoting and citing Ex. 1046, 237–238, 253–254, 289– 290; citing Ex. 1003 ¶¶ 95–106; Ex. 1005, 5:7–17, 5:44–55; Ex. 1009, 2:11– 16, 2:67–3:18, Fig. 2; Ex. 1010, 2:27–32, 5:14–22; Ex. 1013, 431; Ex. 1030, 24).

      “5. “Aid the Movement of Minority Carriers” Patent Owner argues that the Petition fails to show that the applied prior art references disclose the claim limitations “requiring ‘aid the movement of minority carriers,’” as twice recited in claim 1. Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely.

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

      “Claim Construction In an inter partes review, we construe a claim term “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b).” 37 C.F.R. § 42.100(b) (2020). Under that standard, the words of a claim “are generally given their ordinary and customary meaning,” which is “the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention, i.e., as of the effective filing date of the patent application.” Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en banc). The parties agree that, for purposes of this Decision, no claim term needs specific construction beyond its plain and ordinary meaning. Pet. 14; PO Resp. 10. Claim terms need only be construed to the extent necessary to resolve the controversy. Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011). On this record and for purposes of this Decision, we see no need to expressly construe any claim term.” slip op. at 8

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Here, Petitioner argues that a person of ordinary skill in the art (“POSITA”) would have had “at least a Bachelor of Science degree in electrical engineering, or a closely related field, along with at least two years of experience in the design of entertaining lighting systems, and the design and use of LEDs.” Pet. 14 (citing Ex. 1003 ¶ 32). Patent Owner argues that a POSITA would have had “2 to 4 years’ experience in electrical engineering/design of film and television lighting systems, including the design and use of LED lights, combined with two to three years of work experience as a set lighting technician in television and/or motion picture industry.” PO Resp. 9 (citing Ex. 2047 ¶¶ 16–17; Ex. 2100 ¶¶ 156–161). Patent Owner does not identify any specific instance in which the differences between the parties’ respective descriptions of the level of ordinary skill in the art impacts the analysis or conclusions of either party, or either party’s declarant, in this case. In fact, Patent Owner acknowledges that any differences between the parties’ respective descriptions do not impact the conclusions in this case. Id. (“Regardless of which definition of a POSITA is applied, the conclusion(s) would be the same.”). For purposes of this Decision, and to the extent necessary, we adopt Petitioner’s definition of a POSITA because it is consistent with the prior art’s demonstration of the skill level at the time of the invention.” slip op. at 9

      “would have been obvious to combine the cited teachings of Kit and Katzir. Petitioner argues that “Katzir further discloses daylight and tungsten temperature ranges within the claimed temperature ranges.” Pet. 24 (citing Ex. 1006 ¶¶ 53, 54, Figs. 5A, 5B). Petitioner relies on the Holmes Declaration to show that “[a] POSITA would have been motivated to look to Katzir to design an LED array to be retrofit in a fluorescent tube.” Id. at 19 (citing Ex. 1003 ¶ 102). Mr. Holmes testifies that [b]oth Kit and Katzir teach using LEDs of various colors in a fluorescent tube form factor, like a T8 or T12 fluorescent tube. Katzir also discloses various LED array layouts that a POSITA would have a looked to when designing an LED tube lighting like that disclosed in Kit. A POSITA would have had strong motivation to look to Katzir to design an LED array to be retrofit in a fluorescent tube form factor. Ex. 1003 ¶ 102 (internal citations omitted). As discussed above, however, the cited passages of Kit describe a light with LEDs that produces a single, consistent temperature of warm white, commercial white, or cool white. Ex. 1004, 3:28–36, 22:9–25. Neither Petitioner nor Mr. Holmes sufficiently explains why a POSITA would have modified Kit to include Katzir’s particular layout that includes both cool white LEDs and warm white LEDs. See Pet. 19, 24; Ex. 1003 ¶ 102; In re Nuvasive, Inc., 842 F.3d 1376, 1382 (Fed. Cir. 2016) (instructing that we must articulate a reason why a POSITA would combine the prior art references). We identified the aforementioned deficiencies for this asserted challenge in the Decision on Institution. DI 21–23. Petitioner did not address those deficiencies in the Reply. See generally Reply; Tr. 6:16–7:10. Thus, based on the entire record developed at trial, and for the foregoing reasons, Petitioner has not shown that claim 1 would have been obvious over Kit, Ianiro, Ducharme, and Katzir.” slip op. at 13

    • Expert testimonyPetitioner expert discountedOther

      “Petitioner asserts that Mr. Holmes cited Hasnain’s heat dissipation techniques. Reply 10 (citing Ex. 1003 ¶ 490; Ex. 1049 ¶¶ 41–49). Paragraph 490 of Exhibit 1003 relates to Ducharme, not Hasnain, and thus, does not support Petitioner’s argument. Although paragraphs 41 to 49 of Exhibit 1049 span more than seven pages, other than the single citation in the Reply, Petitioner does not discuss any of the testimony presented therein. We, thus, do not consider this portion of the Holmes Supplemental Declaration. See 37 C.F.R. §§ 42.6(a)(3). Furthermore, we would not be persuaded by Mr. Holmes’ testimony even if we considered it. For example, Mr. Holmes testifies that Hasnain’s heat-dissipating structure “a variety of heat dissipating techniques are disclosed by Hasnain, any one of which could readily be used in a T12 form factor LED light, as expressly recognized by Hasnain.” Ex. 1049 ¶ 46. We disagree with Mr. Holmes that Hasnain teaches enclosing its heat-dissipating structure in a fluorescent light tube. Hasnain teaches “a replacement LED light source for fluorescent tube 22 [that] plug[s] into the same connectors and operate[s] from the voltage patterns generated by the ballasts.” Ex. 1008, 3:23–26. Hasnain also teaches that “the replacement LED light source has a plurality of LEDs mounted on a heat-dissipating substrate that has a width that is less than or equal to the diameter of the fluorescent tube that the light source is designed to replace.” Id. at 5:52–56. Thus, Hasnain teaches that its LED light fits into, and connects with, an existing structure that previously held a fluorescent light tube. Id. at 2:50–56, 3:23–26, 4:58–64, 5:52–56, Figs. 1A, 4. As discussed above, however, Hasnain’s heat-dissipating structure is not enclosed in a tubular housing in order to dissipate heat to the surrounding air or via thermal contact with the existing structure that a fluorescent light tube is inserted into. Id. at 2:50–56, 4:23–28, 4:51–64, Figs. 1A, 3, 4.” slip op. at 22
