“Petitioner argues that at the time of the ’909 patent (2004), a person of ordinary skill in the art would have had “a Ph.D. in electrical engineering, physics, materials science, or a related field, and at least one year of experience in the research, design, and/or development of magnetic/spintronic devices, or the equivalent,” or “a Master’s degree in electrical engineering, physics, materials science, or a related field, and four years of experience in the research, design, and/or development of magnetic/spintronic devices, or the equivalent,” where “[l]ess work experience may be compensated by a higher level of relevant education, and vice versa.” Pet. 18–19. In the Decision on Institution, we agreed with and applied Petitioner’s proposed definition. Dec. on Inst. 9. Patent Owner does not propose a different level of ordinary skill in the art in its Response. Both experts utilized Petitioner’s proposed definition. See Ex. 1024 ¶ 25; Ex. 2053 ¶¶ 29–30.

“B. Claim Interpretation We interpret the claims of the challenged patent using the same claim construction standard that would be used to construe the [claims] in a civil action under 35 U.S.C. 282(b), including construing the [claims] in accordance with the ordinary and customary meaning of such [claims] as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner argues that “the claim terms should be given their plain and ordinary meaning and no claim construction is necessary.” Pet. 15. We did not interpret any terms in the Decision on Institution. Dec. on Inst. 9–10. Patent Owner does not propose interpretations of any claim terms in its Response. We conclude, based on the full trial record, that no term requires express interpretation to determine whether Petitioner has met its burden to prove unpatentability of the challenged claims. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (emphasis added) (citation omitted)).” slip op. at 8

“Pursuant to 37 C.F.R. § 42.23(b), “[a] reply may only respond to arguments raised in the corresponding . . . patent owner response.” “‘Respond,’ in the context of 37 C.F.R. § 42.23(b), does not mean proceed in a new direction with a new approach as compared to the positions taken in a prior filing.” Patent Trial and Appeal Board Trial Practice Guide § II.I, available at https://www.uspto.gov/patents/ptab/trial-practice-guide (last updated Dec. 12, 2025). “While replies . . . can help crystalize issues for decision, a reply . . . that raises a new issue or belatedly presents evidence may not be considered.” Id. An indication that a new issue is improperly raised in a reply is where a petitioner submits “new evidence necessary to make out a prima facie case” of unpatentability, such as a “newly raised rationale to combine the prior art references that was not expressed in the petition.” Id. That is the case here. Petitioner’s rationale in the Petition for why a person of ordinary skill in the art would have been motivated to lower Bowen’s 0.9 eV barrier height to 0.33 eV based on Soukup was that such an artisan would have expected lowering the barrier height to increase TMR. See Pet. 34–36. Faced with Dr. Bokor’s testimony on cross-examination, Petitioner presents a new theory in its Reply that a person of ordinary skill in the art would not have known what impact lowering the barrier height would have (increase TMR, decrease it, or have no impact at all), but would have expected it to change in some “uncertain” way, which is a “legally sufficient motivation” in Petitioner’s view. See Reply 6–10, 13–16, 23–25. In other words, “[r]ather than explaining how its original” position that lowering barrier height would increase TMR “was correct,” Petitioner articulated “an entirely new theory . . . absent from the [P]etition” after Patent Owner cross-examined Dr. Bokor and “pointed out the flaws of [Petitioner’s] position” in its Response. See Wasica Finance GmbH v. Continental Auto. Sys., Inc., 853 F.3d 1272, 1286 (Fed.

“Ultimately, the cross-examination testimony above is inconsistent with Dr. Bokor’s opinions in his declaration that, for example, “[i]t was understood to one of skill that lowering the barrier height to increase tunneling would have increased the TMR,” and “[o]ne of skill would have been motivated to adjust oxygen vacancy defects to improve TMR by lowering the barrier height.” See Ex. 1024 ¶¶ 176, 277 (emphasis added); see also id. ¶ 172 (“[O]ne of skill in the art would have been motivated to use [Soukup’s 0.33 eV] or similar height in an MgO MTJ to improve tunneling and hence TMR in Bowen.”). Accordingly, we do not find Dr. Bokor’s declaration testimony regarding a motivation to lower Bowen’s barrier height credible. It is Petitioner’s burden to provide a reasoned, evidence-supported explanation for why a person of ordinary skill in the art would have been motivated to lower Bowen’s 0.9 eV barrier height to 0.33 eV as disclosed in Soukup. See NuVasive, 842 F.3d at 1383; Magnum Oil, 829 F.3d at 1380; TriVascular, 812 F.3d at 1066. Petitioner’s reasoning in the Petition that lowering the barrier height (by introducing oxygen defects) would increase TMR is unsupported by evidence.” slip op. at 31

Inst. Dec. 9–13 (referring to the ’854 patent Specification, the language of claim 1, and Dr. Shamos’s testimony). However, we did not determine whether an “OVER file” included “tokens” as a general matter, or further elaborate on what additional characteristics might be required to qualify as an “OVER file,” because it was not necessary for purposes of Institution.

“In its Response, Patent Owner stated that it “agrees in substance with the Board’s construction” of this term, and clarified its understanding of that construction as requiring that “the issuing agency has verified the ‘virtual representation’ (and not the ‘credential’) to be ‘a first official representation of the original credential.’” PO Resp. 11–12. In its Reply, Petitioner points to Patent Owner’s reliance on an example in the ’854 patent Specification involving the checking of a driver’s license identification number against a DMV database to show verification of information in an OVER File generation request. Reply 2 (citing PO Resp. 14–16; Ex. 1002, 6:35–39, 6:54–65).

“Although we agree with Petitioner that Oborne teaches that “‘device fingerprinting may be utilized’ to provide ‘additional security’ for use of Oborne’s tokens,” Pet. 34 (citing Ex. 1011 ¶ 26 (emphasis added)), we do not agree with Petitioner’s arguments related to “device fingerprinting.” Petitioner also relies on testimony from Dr. Shamos to support its position. However, Dr. Shamos’s cited testimony in paragraph 239 merely repeats what is stated in the Petition, does not provide citation to any other evidence of record, and does not provide any further explanation as to why one of ordinary skill would have been motivated to use device fingerprinting to tie a given token to a given device such that the token for the second device would be invalid in the first device. Ex. 1005 ¶ 239. Dr. Shamos refers to Oborne’s disclosures on “digital fingerprinting” and a client’s MAC address in the token data structure. Id. (citing Ex. 1011 ¶¶ 26, 47). We have considered Petitioner’s arguments in light of Oborne’s disclosure, but find Dr. Malek’s responsive testimony to be more persuasive. We agree with Dr. Malek that, in Oborne, “device fingerprinting simply refers to identifying a device and the user associated with that device.” Ex. 2009 ¶ 111. Specifically, paragraph 26 of Oborne (quoted above) discloses authentication of a user, where “device fingerprinting” is utilized to verify a user’s identity where a user exclusively uses a client device such as a smartphone or laptop computer. Ex. 1011 ¶ 26 (emphasis added). The use of the device fingering for determining the device identity in order to authenticate a user is corroborated by the disclosures in paragraph 47 of Oborne which refer, in part, to the “<client_details” which can include a “<client_type>smartphone” and “client_fingerprint>font list, MAC address, memory size, memory.” Id. ¶ 47 (emphasis added). So, contrary to Petitioner’s arguments, we do not discern any disclosure in Oborne that “device fingerprinting” ties a token to a particular device. See Ex. 1011 ¶¶ 26, 47. Rather, Oborne’s disclosures support Dr. Malek’s testimony that “device fingerprinting could be used to limit a token to a set of fingerprinted devices, such as each device belonging to the user.” Ex. 2009 ¶ 113. Moreover, Petitioner (and Dr. Shamos’s) statement that “the first device’s fingerprint would not match” the fingerprint for the second device merely provides a possible outcome of device fingerprinting, but does not explain why one of ordinary skill would be motivated to use device fingerprinting to make the “second device’s token . . . invalid in the first device,” or make the “token for a second device . . . a new credential,” or point to disclosures in Oborne that would support such a motivation. Id. Thus, we find that Petitioner’s contentions as to this limitation lack sufficient specificity to explain how Oborne teaches the limitation. See Netflix, Inc. v. DivX, LLC, 84 F.4th 1371, 1377 (Fed. Cir. 2023) (“Ultimately, it is the petitioner’s burden to present a clear argument.”); Intelligent Bio-Sys., 821 F.3d at 1369 (“It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’ ” (quoting 35 U.S.C. § 312(a)(3))).

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

“1[e], together with limitation 1[f], and note that we are not performing claim construction of a specific claim term or phrase per se. Claim 1 of the ’608 patent recites that “each respective buffer circuit including a data path corresponding to each data signal line in the respective set of data/strobe signal lines” [limitation 1[e]] and “wherein the data path corresponding to the each data signal line includes” . . . “a delay circuit configured to delay a signal through the data path by an amount . . . ” [limitation 1[f]]. Ex. 1001, 19:36–55 (emphasis added). The operative issue is the identification of the “data path” that is claimed in claim 1. The claim differentiates between data signal lines and strobe signal lines. Limitation 1[e] identifies that “a data path” corresponds to the data signal line in the set of data/strobe signal lines; that is, it is a data path that is in the data signal line. The data path claimed, therefore, is not in a strobe signal line of the set of data/strobe signal lines. Limitation 1[f] confirms this understanding, reciting “the data path,” (with the antecedent of “a data path” of limitation 1[e]), that corresponds to each data signal line, and which includes a delay circuit that delays a signal through the data path. Patent Owner refers to Figures 3, 4A, and 4B of the ’608 patent, which confirms this understanding of the language of claim 1 in that it provides written description support for the reading of the explicit language of claim 1. See PO Sur-reply 1–2. These figures, as well as their associated descriptions, support that there are different transmission lines (data paths) with a separate signal transmission line for transmitting/receiving data signals and a separate strobe line for transmitting/transmitting strobe signals. See Ex. 1001, 10:31–11:8, 11:20– 45, Figs. 3, 4A–4B, see also id. code (57) (identifying that the “data path” corresponds with the data signal line in the set of data/strobe signal lines).” slip op. at 16

Google LLC, 54 F.4th at 1381 (citing In re Freeman, 30 F.3d 1459, 1465 (Fed. Cir. 1994) (emphasis added)). The issues in this proceeding and those at issue in the -00236 IPR are not identical. The claims of the ’035 patent and the instant ’608 patent are different. Claim 1 of the ’035 patent recites “each respective buffer circuit including data paths for transmitting respective data and strobe signals associated with the first memory operation and logic configured to respond to the module control signals by enabling the data paths,” “wherein the logic is further configured to obtain timing information based on one or more signals . . . to control timing of the respective data and strobe signals on the data paths.” Ex. 1031, 19:35– 45. Claim 1 of the ’035 patent explicitly recites that the data paths have data and strobe signals transmitted on them. That is unlike claim 1 of the ’608 patent at issue here—claim 1 of the ’035 patent does not recite that the “data path” is “corresponding to each data signal line in the respective set of data/strobe signal lines,” as claim 1 of the ’608 patent does.” slip op. at 20

“threshold values” includes GPS signal level thresholds, we start with the words of claim 8. Claim 8 recites a “battery power level monitor” that (1) “measures a power level of the charging unit” and (2) “adjusts a power level applied to location tracking circuitry responsive to one or more signal levels.” Claim 8 further recites that “the power level compris[es] a multitude of threshold values determined by a user or system administrator.” The remainder of claim 8 states the purpose of the “multitude of threshold values,” which is “to intermittently activate or deactivate the location tracking circuitry to conserve power of the charging unit in response to the estimated charge level of the charging unit.” The natural reading of these recitations is that the “power level” associated with the “multitude of threshold values” is the battery power level that is (1) measured by the battery power level monitor and (2) adjusted by the battery power level monitor and applied to location tracking circuitry. We also note that the claim language already incorporates a limitation directed to “signal levels” insofar as the battery power level monitor “adjusts a power level applied to location tracking circuitry responsive to one or more signal levels” (emphasis added). As such, the limitation “one or more signal levels” is recited separately from the limitation “the power level comprising a multitude of threshold values.” Given “[t]he general presumption that different terms have different meanings,” Chicago Bd. Options Exch., Inc. v. Int’l Sec. Exch., LLC, 677 F.3d 1361, 1369 (Fed. Cir. 2012), we ascribe different meanings to the recited “signal levels” and “power level.”” slip op. at 15

Reply 16–18. As discussed above, however, “the power level comprising a multitude of threshold values” refers to battery power level thresholds. See supra § II.C.2. We also determine above that signal level threshold values are not within the scope of “the power level comprising a multitude of threshold values.” See id. Accordingly, we are not persuaded that Sakamoto’s GPS signal level thresholds K1 and K2 teach the recited power level threshold values. Although Petitioner is correct that “Sakamoto uses the same modes with both sets of thresholds” and that both sets of thresholds might ultimately relate to conserving battery power (see Pet. Reply 17 (citing Ex. 1003 ¶ 58; Ex. 1004 ¶¶ 27–29)), we are not persuaded that these different types of thresholds are interchangeable within the scope of “the power level comprising a multitude of threshold values.” This is particularly true given that Petitioner already relies on Sakamoto’s GPS signal level thresholds K1 and K2 for teaching another aspect of claim 8, i.e., “responsive to one or more signal levels.” See Pet. 49–50. For these reasons, Petitioner has only established that Sakamoto teaches two battery power level thresholds within the scope of “the power level comprising a multitude of threshold values.” Because two threshold values are not a “multitude” (see supra § II.C.1), we find that Petitioner has not established that Sakamoto teaches “the power level comprising a multitude of threshold values,” as recited in claim 8. Thus, we determine Petitioner has not shown by a preponderance of the evidence that the subject matter of claim 8 would have been obvious over Sakamoto. 3. Claims 10, 13, and 15 Claims 10, 13, and 15 each depend from claim 8. Ex. 1001, 17:4–10, 17:23–25, 17:29–33. Petitioner’s analysis for these claims does not cure the deficiencies discussed above with respect to claim 8. See Pet. 54–55.

“We disagree with Petitioner’s interpretation. Taking Petitioner’s point that “‘specified data rate’ means only that the data rate is specified in some way” (Pet. Reply 4), we do not see how, once the rate is specified, claim 1’s later recitations of “the specified data rate” could refer to any other rate, as Petitioner’s arguments suggest. Petitioner argues that “it is clear that the ‘specified data rate’ that provides antecedent basis for later recitations of that term is merely the data rate specified for ‘communicat[ing] data’ between the ‘memory module’ and the external ‘memory controller of the computer (alteration by Petitioner). We agree with this statement, and later recitations of “the specified data rate,” therefore, refer to the data rate that is so specified.

“PO Resp. 19; see also Ex. 2003 ¶¶ 68–72 (Dr. Przybylski’s testimony explaining this annotated figure). Halbert’s Figure 5 is a timing diagram for two consecutive read operations (Ex. 1005 ¶¶ 16, 37), and Patent Owner includes annotations to show each of ranks 140 and 142 outputting data onto their respective data busses at half the rate that data are output from data interface circuit 120 on the DQ data line. In particular, Halbert explains that each of ranks 140 and 142 is “capable of performing m-bit-wide data transfers.” Ex. 1005 ¶ 30. On a read command, rank 140 sends m-bit-wide data to bi-directional data register 126 on line RDQ0 at the same time that rank 142 sends m-bit-wide data to bi-directional data register 128 on line RDQ1, as shown in Figure 5 between T7n and T8n. Ex. 1005 ¶¶ 31–32, 39. Halbert discloses that register 126 or from register 128 to output to buffer 122, which are then output on line DQ. Ex. 1005 ¶ 33. Halbert explains that “[d]ata is serialized from the data registers onto the memory data bus by reading 2m bits into the data registers during one memory device read cycle, and then driving these bits, m at a time, through MUX 124.” Ex. 1005 ¶ 33. As shown in Halbert’s Figure 5, over one clock cycle (T7n–T8n), each of ranks 140 and 142 outputs one piece of m-bit-wide data, and over one clock cycle (T8–T9), those two pieces of m-bit-wide data are output on line DQ to the system memory data bus. Halbert explains that the second read operation proceeds in the same fashion as the first and that “[t]he net result is that the memory data bus transfers 4m bits of data in two memory bus clock cycles (four mbit transfers), with only two data accesses performed at each memory device on the module.” Ex. 1005 ¶ 42.

“We find that paragraph 75 of Dr. Bederson’s original Declaration that his testimony “show[s] how Keely’s touch-sensitive plane can be used as Geva’s planar element” (Ex. 1002 ¶ 75 (emphasis added)) is consistent with Patent Owner’s position that the proposed combination in the Petition does not include Geva’s planar element 14. We find that Dr. Bederson’s testimony that “[p]erhaps I could have been more precise by using the word ‘with’ in place of ‘as’ in this sentence, since that is what Geva itself teaches and what I relied on in forming my opinions” (Ex. 1044 ¶ 13) is not a clarification of his initial testimony, but, instead, is a clear revision of his testimony and his opinion. Dr. Bederson’s testimony regarding “using the word ‘with’ in place of ‘as’” (id.) is improper new testimony in his Reply Declaration. Furthermore, Dr. Bederson’s testimony that his new opinion is supported by “what Geva itself teaches” (id.) is not consistent with Geva’s teachings. Geva does not refer to Keely’s LCD or any LCD similar to that in Keely with a digitizer grid, but instead, Geva describes “[a]dvantageously, the position-determining input device does not require a specific, active board with in-built sensors for determining positions.” Ex. 1011, 3:7–9. which the opinion is based is entitled to little or no weight.” 37 C.F.R. § 42.65(a).
