      “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

    • BurdenNot shown unpatentable

      “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. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein. Ex. 1007 ¶ 52. Petitioner’s expert, Dr. Shealy states that he understands paragraph 52 to mean that it is “fair game to pull the recess out of any of those figures [Figures 1A through 6].” Ex. 2004, 39:12–21.

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.

      “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.

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

      “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. Id. at 1591. According to Petitioner, “it is not obvious” to modify an OCT imaging system to achieve a depth and scanning range that is ten times larger than that disclosed in the art.

We further note that the prior art itself demonstrates the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)).” slip op. at 11

      “C. Claim Construction We construe claims 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. Therefore, we construe the challenged claims under the framework set forth in Phillips v. AWH Corp., 415 F.3d 1303, 1312–19 (Fed. Cir. 2005) (en banc). Under this framework, claim terms are given their ordinary and customary meaning, as would have been understood by a person of ordinary skill in the art (“POSA”), at the time of the invention, in light of the language of the claims, the specification, and the prosecution history of record. Id. Only those terms that are in controversy need be construed and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Matal, 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). We have considered Petitioner’s claim construction proposals (see Pet. 21–23), which are uncontested (see generally Resp., not addressing construction), and find that it is not necessary to expressly construe any claim term for purposes of rendering this Decision.” slip op. at 13

      “In the Patent Owner Response, Patent Owner acknowledged the Board’s characterization of the knowledge of an ordinarily skilled artisan as consistent with the proposals of both parties (PO Resp. 12–13), and neither party further addressed the proper level of ordinary skill in the art or disagreed with our characterization from the Institution Decision. See PO Resp., Reply. Our determination regarding the patentability of the challenged claims does not turn on the differences between the parties’ definitions. We adopt Petitioner’s assessment, but note that our conclusions would be the same under Patent Owner’s assessment. C. Testimony of Dr. Akhlaghi” slip op. at 9

      “We agree with Petitioner that Dr. Akhlaghi’s qualifications and deposition testimony, when read in context, indicate that Dr. Akhlaghi is sufficiently experienced to opine on the knowledge of one of skill in the art at the time of the ’866 patent. As noted in the August 13, 2018 update to our Trial Practice Guide: An expert witness must be qualified as an expert by knowledge, skill, experience, training, or education to testify in the form of an opinion. Fed. R. Evid. 702. There is, however, no requirement of a perfect match between the expert’s experience and the relevant field. SEB S.A. v. Montgomery Ward & Co., 594 F.3d 1360, 1373 (Fed. Cir. 2010). A person may not need to be a person of ordinary skill in the art in order to testify as an expert under Rule 702, but rather must be “qualified in the pertinent art.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64 (Fed. Cir. 2008). See Notice of Update to Office Patent Trial Practice Guide, 83 Fed. Reg. 156, (Aug. 13, 2018) (text of update available at https://www.uspto.gov/sites/default/files/documents/2018_Revised_Trial_Pr actice_Guide.pdf). In addition, we are well able to consider the value of an expert opinion and afford it appropriate weight. Perreira v. Secretary of the Dept. of HHS, 33 F.3d 1375, 1377 n.6 (Fed.

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionDecided for patent owner

      “Tmax” In our Institution Decision, we noted that the term “Tmax” appears in each of the challenged claims, and that both parties agreed that Tmax should be construed as stated in the Specification: “the time period which elapses after administration of the dosage form at which the plasma concentration of the drug attains the highest plasma concentration of drug attained within the dosing interval (i.e., about 24 hours).” Inst. Dec. 7 (citing Pet. 24; Prelim Resp. 18; Ex. 1001, col. 7, ll. 49–53). We concluded that the proposed definition was consistent with the Specification and defined the claim term with reasonable clarity, deliberateness, and precision, and we adopted the parties’ construction. Neither party addressed the issue of construction of Tmax in further briefing, but the parties disagree about how Dr. Akhlaghi applied the definition in her testimony. See, eg., Pet. Reply 9–10. For purposes of analyzing the patentability of the challenged claims, we continue to interpret the term as “the time period which elapses after administration of the dosage form at which the plasma concentration of the drug attains the highest plasma concentration of drug attained within the dosing interval (i.e., about 24 hours),” because that definition is consistent with the Specification, and because the parties themselves agreed to the definition of Tmax.
