“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. Upon review of the full record, we see no reason to modify, and we thus maintain, the definition of a POSITA applied in our Decision on Institution.

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.

“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.

“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.

“summarized above, we find Patent Owner to have the better position. In particular, we agree with Patent Owner that the combination of Hsia and Black fail to teach or suggest simultaneously delivering non-overlapping beams. The combination also fails to teach or suggest producing beam patterns that include both overlapping and non-overlapping beams. PO Resp. 34. To begin, while we recognize that Hsia discloses overlapping and non-overlapping treatment patterns, those patterns are achieved by the sequential delivery of laser beams as a user physically moves a single handpiece that delivers a single beam across the skin of a patient. Ex. 1004 ¶ 68, Figs. 8 and 9; Ex. 2001 ¶¶ 73–74. Black does not cure that deficiency as Black does not disclose treatment with non-overlapping beams. Ex. 2001 ¶ 99. Black discloses using a “refractive optics, mirror-based optical delivery device” for the simultaneous delivery of multiple overlapping laser beams. Ex. 1006 ¶¶ 12– 13. The beams align on an optical path and, using different laser beam parameters, deliver treatment at various depths within a combined beam path. Id. ¶¶ 54, 58–59. Thus, while Black may be characterized as creating overlapping beams, we do not find sufficient support for a finding that Black teaches or suggests creating non-overlapping beams for simultaneous delivery, and the claims require both.

“(2) Our analysis We agree with Patent Owner. Patent Owner’s plain reading of limitation 1(c) is correct, and under this reading, the combination of Shackle and Birrell fails to disclose or suggest limitation 1(c). Limitation 1(c) states in part: “at least one LED circuit having any number of LEDs . . . needed to approximately match the forward voltage drop of a first input voltage to the LED driver.” Ex. 1001, 27:22–25 (emphasis added). We have omitted the language “connected in series or series parallel” to highlight the grammatical relationship between the noun phrase “any number of LEDs” and the verb phrase “needed to approximately match.” The plain reading of this limitation is that the at least one LED circuit has any number of LEDs needed to approximately match the forward voltage drop of the LED driver input. Petitioner’s reading, that “the at least one LED circuit,” rather than “any number of LEDs,” must approximately match the forward voltage drop of the LED driver input, is strained and not grammatically plausible. See Reply 1–3. Petitioner does not assert there is an express disclaimer or disavowal in the specification that supports its position; Petitioner instead relies on examples disclosed in the specification to support its faulty interpretation of limitation 1(c). See Reply 2–3. These arguments are unpersuasive. It is axiomatic that we must not “limit[] the claimed invention to preferred embodiments or specific examples in the specification.” Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1346–47 (Fed. Cir. 2015). Not only that, but Petitioner’s citations to the specification better support Patent Owner’s position. In Petitioner’s view, the specification requires other non- LED components to be combined with one or more LEDs to “appropriately match the voltage.” Reply 2. The main example Petitioner relies on describes 38 LEDs having a total voltage drop of 114 V in a circuit with a bridge rectifier having a 6 V voltage drop. Id. at 2–3 (citing Ex. 1001, 16:64–17:7). Yet the 114 V voltage drop of the LEDs alone “approximately matches” the input voltage of 120 V, without the contribution of the bridge rectifier (6 V). Id. Indeed, 114 V out of 120 V is a 95% match. Thus, this example supports Patent Owner’s view that it is the voltage drop of the LEDs themselves, not the LED circuit as a whole, that must approximately match the LED driver input.

Pet. 48 (“Piepgras provides for configurations where a reflective platform (reflective substrate) mounts lighting system 500 in a manner applicable generally to the inventions of Piepgras . . ., and thus including the rope lighting application discussed above.”).

“The evidence of record demonstrates, however, that modifying an existing corneal surgery system to image and perform surgery on the lens was not the simple task asserted by Petitioner. For example, in a patent application filed in November 2009, Petitioner asserted that due to the different depth ranges for the laser’s focus, “laser systems designed for corneal procedures do not offer solution[s] for the considerable challenges of performing surgery on the lens of the eye.” Ex. 2007, 4:65–67, 5:30–36, code (22). Similarly, in a different patent filed in December 2008, Petitioner outlined the various challenges in developing laser surgery systems for creating incisions in the lens, including the difficulty in focusing a laser beam that propagates through regions of the eye with different optical properties and different curvatures. Ex. 2014, 15:51–16:18, code (22). This patent then states: Because of all the described hard challenges, corneal surgical laser systems are qualitatively simpler than lens surgical lasers. This is well supported by the fact that even though corneal surgical systems were suggested about 40 years ago, none have been adapted successfully for lens surgery to date. Id. at 16:13–18. During prosecution of another patent filed in 2008, and in responses to office actions filed in 2012 and 2013, Petitioner argued that a corneal OCT system “simply will not work” on the lens and that it would not have been obvious to modify such an OCT system to image the lens. Ex. 2015, 898, 1591, 1788. This was because OCT systems designed to image the lens would be required to deliver and scan an imaging beam “to a depth ten times bigger and a depth range ten times bigger” than an OCT system designed to image the cornea.

“Turning to the disputed term “automatically” in this context, we agree with Patent Owner that the plain meaning of the term “automatically” is that the “control system” can, on its own and without human intervention, perform the subsequently recited step. Resp. 11–15; see also Pet. 10 (Petitioner agreeing this is the plain meaning). This is supported by the Specification, which states, inter alia, that “the entire system is controlled by the controller CPU” and describes alternative embodiments where (1) the system is fully in control and where (2) user input identifies targets. Ex. 1027, 12:23–25, 13:25–44, Figs. 14, 15. However, we also agree with Petitioner that just because the claimed “control system” is configured/programmed to perform (i.e., capable of performing) some tasks “automatically” (i.e., entirely on its own), this does not mean user input (e.g., from a surgeon) must be altogether excluded. Pet. 10–11. In fact, user input must be possible and is within the scope of the independent claim. “By definition, an independent claim is broader than a claim that depends from it, so if a dependent claim reads on a particular embodiment of the claimed invention, the corresponding independent claim must cover that embodiment as well.” Littelfuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed. Cir. 2022). Here claim 2, requiring automatic target identification, and claim 5, requiring user input on target identification, each depends from claim 1 and illuminates its scope, which must be broad enough to encompass both. Thus, although requiring (in claim 1) that a “control system” can perform certain recited functions, and that some are performed (according to claim 2) “automatically,” that same “control system” must also be capable of allowing a user input on the locations of targets for laser treatment (according to claim 5). Such optional user input required by dependent claim 5 is described in the Specification, which includes embodiments where a surgeon can adjust the size, location, and shape of the treatment pattern, can determine the optimal cutting contours in patients, and can provide “user input” to define targets or adjust computer-defined parameters as necessary. Ex. 1027, 10:55–45; 10:67–11:2, 13:25–55, 13:63–14:2. Regardless, the configuration of independent claim 1’s “control system,” which must be programmed to and capable of performing its own recited steps/functions, is not diminished by the requirements of either dependent claim.

Ex. 1030, 17:30–51 (claim 1). We address Patent Owner’s respective arguments and our analysis below. “The presence or absence of a reasonable expectation of success is . . . a question of fact.” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1366 (Fed. Cir. 2016). “The reasonable expectation of success requirement refers to the likelihood of success in combining references to meet the limitations of the claimed invention.” Id. at 1367. The evidence of record suggests that the ordinarily skilled artisan would not have had a reasonable expectation of success in achieving the claimed invention based on Swinger’s, Baikoff’s, and Li’s teachings. Further, as our reviewing court has explained, “references to ‘common sense’—” or an ordinarily skilled artisan’s ordinary creativity, “whether to supply a motivation to combine or a missing limitation—cannot be used as a wholesale substitute for reasoned analysis and evidentiary support, especially when dealing with a limitation missing from the prior art references specified.” DSS Tech. Mgm’t, Inc. v. Apple Inc., 855 F.3d 1367, 1374 (Fed. Cir. 2018) (quoting Perfect Web Techs. Inc. v. InfoUSA, Inc., 587 F.3d 1324, 1326 (Fed. Cir. 2009)). Although here Petitioner has not wholly omitted any reasoned analysis or evidence regarding the claimed computer control system programmed to automatically plan a cutting region based on image data and then perform that planned laser-cutting of the lens capsule (and, for some claims, also the lens), this subject matter is not disclosed in any cited art and we find Petitioner’s evidence and reasoning as to why it would have been obvious without such disclosure to be largely conclusory and unpersuasive.” slip op. at 40
