“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

“understanding of a person of ordinary skill in the art (sometimes abbreviated herein as “POSITA”). Graham, , 383 U.S. at 17–18. Petitioner argued that a person of ordinary skill in the art would have had a “at least a four-year degree in electrical engineering, chemical engineering, physics, or material science or a closely related field and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies. Additional education could substitute for professional experience and vice versa.” Pet. 11 (citing Ex 1003 ¶ 69). Patent Owner did not dispute this proposed definition prior to institution. See generally Prelim. Resp. In our Decision on Institution, we adopted Petitioner’s proposal. After institution, Patent Owner asserted a slightly different definition of a POSITA, namely someone who “would have possessed at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” Resp. 17. Relevant graduate education could substitute for the professional work experience. Id.

“Thus, although both parties indicate that no claim construction is necessary at this stage of the proceeding, it is apparent that they disagree as to the meaning of “discrete carbon nanotubes.” While Petitioner appears to construe “discrete carbon nanotubes” as “nanotubes that are generally individually distinct” (Pet. 13), Patent Owner argues a more restricted construction requiring that “discrete carbon nanotubes” not be reacted with other components. Prelim. Resp. 3. The evidence relating to claim 10 In quotations from the Preliminary Response throughout this Decision, we have retained bolding and underlining added to the text by Patent Owner. construction that Patent Owner offers on the current record, however, does not address its proposed restriction.

As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“draws a distinction between foreground and background objects. Specifically, the prosecution history makes it clear that foreground objects are “in the forefront of the game play as primary objects to be manipulated or used during game play” and that background objects are “outside the primary focus of game play and as unexpectedly interactive components.” Ex. 1002, 85. However, whether an object is “outside the primary focus of game play and as unexpectedly interactive components” is based solely on the subjective perspective of the user. That is, what one user may consider a primary focus or expected object, another might consider outside the primary focus and unexpected. As the Director made clear in the Remand Decision, it is “improper[]” to have a claim construction “based on the subjective perspective of a user.” Remand Dec. 7; see also Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1353 (Fed. Cir. 2001) (“We are not prepared to assign a meaning to a patent claim that depends on the state of mind of the accused infringer.”). Accordingly, we cannot and do not adopt that as our construction of the term background. Not finding a construction of “background” based on the intrinsic evidence, we turn to the extrinsic evidence. See Remand Dec. 7 (“[T]he Board should resolve the proper meaning of that term by first assessing the intrinsic evidence, and then consulting extrinsic evidence if necessary.” (emphasis added)). Specifically, as part of the Decision Denying Institution, we considered various dictionary definitions of the word “background.” According to those definitions, “background” refers to “[t]he part of a pictorial representation that appears to be in the distance and that provides relief for the principal objects in the foreground.” Ex. 3002 (AMERICAN HERITAGE DICTIONARY); see also Ex. 3003 (“the scenery or ground behind something,” “the part of a painting representing what lies behind objects in the foreground”) (MERRIAM-WEBSTER DICTIONARY). Consistent with those dictionary definitions, we construe the term “background” to mean the part of a pictorial representation that is not in the foreground. The prosecution history provides more useful guidance as to what a “non-promotional” object is. As the applicant argued in the Amendment discussed above, a non-promotional object is one “which does not have an ‘area’ in which advertisements directly appear, but instead represents a ‘hot spot’ that, upon activation, causes ‘hidden promotional content’ to then appear.” Ex. 1002, 85–86. In other words, a non-promotional object does not display a promotional message unless the hotspot is activated. This understanding of the meaning of non-promotional is consistent with an earlier argument (Ex. 1002, 113–25) the applicant made during the prosecution of the ’089 patent.12 At that time, the applicant argued: In an exemplary embodiment, the location in-game may be represented by a non-promotional object, such as a blank chalk board depicted in the background of the gaming environment. See Applicant’s Specification at ¶ [0045]. Upon activating the hot spot (e.g., by throwing a dart at the chalk board), a promotional message may be drawn on the chalk board and displayed to the user. See id. In other words, Applicant’s amended claims 15 and 22, inter alia, may present promotional content once the game user activates, unknowingly, a “hot spot” associated with a non-promotional object—the non-promotional object is not an ordinary or visible place for advertisement, the 12 This argument was made on December 2, 2011, which is prior to the amendment adding the term background on July 15, 2013. Compare Ex. 1002, 117 (then pending claim 15 without the word “background”) with id. at 80 (amendment adding “background” to claim 15). user does not know that the object has a hidden hot spot, and the user does not know that activating the hidden “hot spot” will display promotional content.

“Moreover, even if we did consider only the specific references addressed in the Preliminary Response, we would not reach a different outcome. Patent Owner focuses on a high-level comparison of the references. See Prelim. Resp. 13–19. Such high-levels of similarity are to be expected as all of the references involve advertising in computer game programs. But such high-level similarity is not sufficient. See Juniper Networks, Inc. v. Swarm Tech.

Nor were any of Petitioner’s Reply arguments improper. We expressly authorized Petitioner to respond to Patent Owner’s arguments that the prior art relied on in the Petition was substantially the same as prior art that was considered. Ex. 3005 (Email from the Board to the parties) (“Petitioner is authorized to file a preliminary reply brief addressing 1) Patent Owner’s arguments under 35 U.S.C. 325(d). . . .”). Moreover, given the facts of this proceeding, it is not reasonable to require Petitioner to anticipate “substantially the same prior art” arguments and address them in the Petition. Accordingly, Petitioner’s argument is a proper reply argument. 3. Conclusion Based on our consideration of Becton Dickinson factors (a), (b), and (d), we find that the same or substantially the same art or arguments were not previously presented to the Office. Thus, our analysis ends at this point, and we need not proceed to part two of the Advanced Bionics framework. See Advanced Bionics, IPR2019-01469, Paper 6 at 8.

“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.

“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.

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.

“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

“Later, when considering what would ultimately become claim 1 of the ’809 patent, the Examiner did not explicitly address whether the ’985 provisional application supported the applicant’s newly introduced reference to two distinct buffers (i.e., a E-DCH buffer and a HARQ buffer). See Ex. 1002, 152–59, 365–83; see also Pet. 15 (“While Wager was discussed during the ’104’s prosecution . . . , it was not substantively addressed for the ’809; . . . the Claims recite, e.g., ‘HARQ buffer’ elements that are not in the ’104’s claims.” (bolding omitted)). For reasons we discuss more fully below, see infra Section IV.C, we determine that the Examiner erred by failing to revisit, in light of the added reference to a HARQ buffer, whether the ’985 provisional application supported the claims that issued in the ’809 patent. This error was material to the patentability of the challenged claims because the applicant’s arguments responding to the Examiner’s Wager rejections depend on Wager not being prior art. See Ex. 1027, 387–88, 560–62, 754; see also Pet. 15–16 (“The Examiner . . . erred by not rejecting the ’809 Claims over Wager.”).

“the “focus” of factor (c) and “informs” the petitioner’s showing under factors (e) and (f). As to factor (c), Petitioner asserts, and the record shows, Han, Cao, Shin, and Zhao were only listed or cited to in IDSs and were not addressed in any Office Actions. See Ex. 1032. Further, as Petitioner notes, there were 810 total references, and these references were cited in a single IDS containing 129 additional references. Id. at 76–82; Ex. 1031, code (56). Petitioner further points out that the record reflects that the Examiner only initialed the IDSs, which contained these many references, and did not issue Office Actions, which is sufficient to demonstrate that there is no evidence that the asserted art was substantively evaluated during examination. See Pet. Prelim Reply 3–5. As Advanced Bionics recognizes, a showing of material error varies depending on the degree to which the previously-presented art was substantively addressed by the Office. Advanced Bionics at 10–11. Turning to factor (e), as Petitioner notes, the record is silent as to how the Examiner viewed the prior art listed in IDSs which is asserted here. We recognize that it is difficult to characterize error in a silent record. In this light, we find that Petitioner’s assertion that the Examiner failed to adequately consider the references, which should have resulted in an Office Action because the references clearly disclose the ’335 patent claimed subject matter, serves as sufficient identification of error under factor (e). Pet. Prelim. Reply 5. Moreover, as discussed above and relevant to factor (f), the evidence presented in the Petition is meritorious, which further demonstrates that the combination of the cited prior art was overlooked during prosecution.
