“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).

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

“In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29.

“For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

“and digital selector 240 disclosed by Zhang is “digital circuitry,” which is configured to receive a plurality of frequencies comprising a plurality of desired/undesired television channels from ADC 220 and to output the desired television channels to demodulators 250 as a digital datastream. Tr. 71:14–17 (PO Counsel: “There is no dispute that in both Zhang and the patent, an RF signal that has both desired and undesired channel comes in and what’s sent to demodulators are desired channels. Nobody is disputing that.”), 134:3–5 (PO Counsel: “The issue is not whether the black box 230- plus-240 is the digital circuitry. It is. The issue is not whether or not that overall circuitry selects channels. At some level, it does.”). In other words, Zhang teaches digital circuitry that is (1) capable of receiving a plurality of frequencies including desired/undesired television channels and (2) capable of distinguishing between the desired/undesired channels to output the desired television channels to a demodulator. We find these uncontested facts to be highly probative of Petitioner’s contention that, to a skilled artisan, Zhang suggests that its digital circuitry is capable of selecting the desired television channels from a digitized plurality of frequencies that include both desired/undesired television channels. This is because Zhang’s digital circuitry is able to take what is input originally as a digitized plurality of frequencies having both desired/undesired television channels and, using those frequencies, pick out the desired television channels that are subsequently output to a demodulator. Zhang teaches that “because only the selected channels are later demodulated” the disclosed digital circuitry is “much faster than traditional analog channel switching through RF tuners” and it “dissipates less heat because fewer resources are required when demodulating only the selected RF channels.” Ex. 1013 ¶ 28 (emphasis added).” slip op. at 22

“ordinary and customary meaning to a POSITA.” Pet. 21. Although Petitioner proposes corresponding structure for the term “digital circuitry” recited in claim 1, it does so only “[t]o the extent” that term “is construed to be a means-plus-function term under 35 U.S.C. 112, paragraph 6.” Id. at 22. But Petitioner does not argue or suggest that “digital circuitry” should be construed as a means-plus-function term; nor does Petitioner make an argument to overcome the presumption that 35 U.S.C. § 112, paragraph 6, does not apply. See id. Patent Owner does not address claim construction. See generally PO Resp. Because neither party actually argues “digital circuitry” is a means-plus-function term, the presumption holds and we determine that no claim term requires express interpretation to resolve any controversy in this proceeding. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999).” slip op. at 8

Pet. 19–45. Petitioner also asserts that these claims would have been obvious over Zhang. Id. Patent Owner disputes certain aspects of Petitioner’s analysis. PO Resp. 3–50.

“system may include a digital video recorder (DVR).” Id. at 45–46 (citing Ex. 1052 ¶¶ 5, 43, 48, 60, 73, 98, 112, 118, 191, 197, 212, 281–285, 296, 546). According to Petitioner, “[a] POSITA would have been motivated to include Reisman’s DVR in Zhang’s STB to provide a more feature-filled and individualized user experience, which in the proposed combination still includes Zhang’s wideband front-end receiver components cited for performing Elements [25A]–[25E].” Id. at 46. Petitioner explains that “Reisman’s DVR improves user experience and flexibility by allowing timeshifted and on-demand viewing, and enabling replay and trick-play (fast forwarding, rewinding, and pausing) of live programming.” Id. (citing Ex. 1052 ¶¶ 191, 197, 212, 284); see also id. at 46–47 (asserting that “[a]dding Reisman’s DVR to Zhang’s system would have been nothing more [than] applying a known technique of integrating a DVR into a set-top box . . . to a known STB . . . that was ready for improvement to yield a predictable result” and that “[a] POSITA would have had a reasonable expectation of success”). Patent Owner does not specifically dispute Petitioner’s contentions in this regard. See PO Resp. Based on Petitioner’s argument and evidence (see Pet. 45–47), we find Petitioner’s proposed combination of Zhang and Reisman teaches all the limitations of claims 25 and 38. We also find that Petitioner’s proffered reasoning for combining Zhang and Reisman supports a legal conclusion of obviousness. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[T]here must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”).” slip op. at 40

“On July 16, 2025, the Acting Director issued her decision, which denied Patent Owner’s request for discretionary denial and referred this case to the Board. Paper 9, 3. The Decision stated “Petitioner provides persuasive reasoning, supported by evidence, that the Office erred in a manner material to the patentability of the challenged patents during patent examination, and, accordingly, discretionary denial under 35 U.S.C. § 325(d) is not appropriate.” Id. The Decision also stated “it is an appropriate use of Office resources to review the potential error.” Id. As stated in the Acting Director’s decision, “the Petitions [in IPR2025-00559; 00636] are referred to the Board to handle the cases in the normal course, including by issuing a decision on institution addressing the merits and other nondiscretionary considerations, as appropriate.” Id. (emphasis added). Thus, the scope of our delegated authority only extends to “the merits and other nondiscretionary considerations.” Accordingly, we do not address the discretionary denial issue raised in the Petition and in the Patent Owner’s Preliminary Response.” slip op. at 6

“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Ltd., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). We do not perceive the need to construe any claim limitation at this time. Our conclusion concerning instituting an inter partes review would be unaffected by a determination that the preambles of the claims are limiting. Accordingly, for this initial Decision to institute an inter partes review, the words “display” or “frame,” and the term “display case” will be given their ordinary and customary meaning as would have been understood by a person of ordinary skill in the art at the time of the invention and in the context of the entire patent disclosure. slip op. at 15
