    “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012). The Technical Data Sheets may support a finding that the Xirallic® products they describe existed as of the dates on the documents, but they do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.” slip op. at 20

    “witnesses. See Elbit Systems of Am., LLC v. Thales Visionix, Inc., 881 F.3d 1354, 1358 (Fed. Cir. 2018) (citing Trs. of Columbia Univ. v. Illumina, Inc., 620 F. App’x 916, 922 (Fed. Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

    “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

    “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. Pet. 25 (citing Ex. 1003 ¶ 81; Ex. 1007 ¶ 52, 66); see also Pet. 40, 45 (citing Ex. 1007 ¶ 52). Neither of these paragraphs provide sufficient motivation to a POSITA to remove the gate recess from Saxler Figure 1A. Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess.

    “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

    “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.

    “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

    “Ex. 1001, 6:28–38 (emphasis added). However, the language of claim 1 is very clear on the functionality of the “open tip,” expressly reciting that “the open tip cuts bone tissue away from the sacrum or the ilium.” Id. at 13:19– 20. Thus, the claim language itself provides the required functionality of the “open tip,” and we do not agree with Petitioner that additional functionality relating to where bone tissue might go once cut, as discussed in the Specification, should be read into the claims as a limitation. Patent Owner’s newly proposed interpretation is similar to Petitioner’s in that it requests addition of functionality discussed as an example in the Specification, but not recited in the claim’s expressly recited functional language relating to the “open tip.” We disagree with Patent Owner that the concept of dislodged tissue entering a void defined by the open tip is necessary to understanding the claim element. And, once more, Patent Owner reads too much structure from the written description into the claim language as a limitation because it is not apparent that the recited “open tip” language requires that we further clarify that any interior void defined by the open tip is on the interior of the abrading head, and behind the exterior abrading surfaces, or between interior surfaces of a first pair of opposing sides, as proposed by Patent Owner. “[W]hile it is true that claims are to be interpreted in light of the specification . . . , it does not follow that limitations from the specification may be read into the claims. . . .

    “A claim limitation is presumed to invoke 35 U.S.C. § 112(f) (or pre- AIA § 112 ¶ 6) if, as here, it explicitly uses the term “means” and includes functional language; this presumption is overcome if the limitation further includes the structure, material, or acts necessary to perform the recited function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc). Here, the word “means” is recited, followed by functional language, and the claim recites no structure associated with the means or function. Moreover, the parties agree that this is a means plus function limitation. See Pet. 19–20; Resp. 9. We find “releasing means” is a means plus function limitation and, based on the plain language of the claim, the recited “releasing means” is a part of the also recited “slide hammer assembly,” as the above-quoted claim language defines. Ex. 1001, 13:10–17. Construing a claim term under 35 U.S.C. § 112(f) involves two steps: (1) identifying the claimed function; and then (2) determining what structure, if any, disclosed in the Specification corresponds to the claimed function.

The combination of Lambert’s statement above with Poykko and other aspects of Lambert, potentially with allegedly obvious modifications of Lambert, may serve as the basis of Petitioner’s arguments for these later limitations involving “virtual bus stops,” but these later allegations do not reach back and redefine Petitioner’s more limited argument with respect to “virtual bus stops” in isolation.8 To the extent Petitioner argues in its Reply that a combination of Lambert and Poykko or other obviousness arguments 8 In our Institution Decision, we noted that Patent Owner, at that stage of the proceeding, failed to properly address Petitioner’s proposed combination of Lambert and Poykko for various “virtual bus stop” limitations. Inst. Dec. 22–23. That said, we do not view the Petition’s arguments and evidence as to “virtual bus stops” limitation in isolation, prior to addressing the “memory” limitation and adding Poykko and obviousness to the analysis, as relying on a combination of Lambert and Poykko or obviousness. See Pet. 25. satisfy the “virtual bus stops” limitation, we agree with Patent Owner that this introduces an improper new theory in the Reply. See PO Sur-reply 20– 22.” slip op. at 29

    “We are persuaded that Patent Owner’s proposal is more consistent with the problems and solutions in the ’583 patent and prior art of record. We agree that Petitioner’s proposal is overbroad in that it encompasses artisans without LED circuit design experience (“and two or more years of experience with LED devices and/or related circuit design . . .” (emphasis added)). Patent Owner’s definition, in contrast, requires “two or more years of experience with LED devices and related LED circuit design.” We therefore adopt Patent Owner’s definition of the level of skill, but we note that the outcome here would not have changed had we adopted Petitioner’s level of skill.” slip op. at 7

    “preliminarily agreed with Patent Owner that “substrate” may mean “a surface where ‘LEDs, capacitors and/or resistors are formed or mounted.’” Pet. 7; Dec. 19 (quoting Prelim. Resp. 22). We instructed the parties to address the meaning of “substrate” more fully at trial. Dec. 19–20 n.13. Post-institution, the parties propose the following competing constructions for the term “substrate”:” slip op. at 8

    “(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. See Sur-reply 6–7.” slip op. at 16

    “combination. The first is that the proposed combination is not at all clear. Although Petitioner need not propose a bodily incorporation of different embodiments, Petitioner must provide a “reasoned analysis” explaining what the combination is. See DSS Tech. Mgmt., Inc. v. Apple Inc., 885 F.3d 1367, 1377 (Fed. Cir. 2018); In re Keller, 642 F.2d 413, 425 (CCPA 1981); see also Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d 1342, 1368 (Fed. Cir. 2012) (“We must be careful not to allow hindsight reconstruction of references to reach the claimed invention without any explanation as to how or why the references would be combined to produce the claimed invention.”) (citation omitted). But the Petition never explains how or where Piepgras’s glass substrate would be combined with Piepgras’s alleged flexible substrate, the rope light of Figure 31. At most, Petitioner suggests incorporating the illumination device 500 of Figure 42 in the rope light of Figure 31. 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.”). As for the glass substrate, Petitioner merely states that “a POSITA would have found it predictable to configure the Shackle-Piepgras device to implement a flexible substrate mounted to the glass substrate, wherein at least one of the plurality of LED packages is mounted to the flexible substrate.” Id. (citing Ex. 1002 ¶ 150). This vague statement just parrots the claim language and does not explain anything about how the glass substrate would be included in the combination.” slip op. at 28
