    “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. Based on the full record developed during trial, including our review of the ’909 patent and the types of problems and solutions described in the ’909 patent and cited prior art, we maintain the previously adopted definition of the level of ordinary skill in the art and apply it for purposes of this Decision.” slip op. at 8

    “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. Cir. 2017). “Shifting arguments in this fashion is foreclosed by statute, [Federal Circuit] precedent, and Board guidelines.” Id.” slip op. at 20

    “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

    “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure.

    “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

    “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

    “Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light). See Tr. 42:10–18 (Patent Owner’s counsel stating that “high-pass” means “there’s a bias or preference for high frequencies”); Ex. 2020, 93:23– 94:15 (Petitioner’s declarant, Dr. Katsaggelos, agreeing that a high-pass system attenuates the low frequency of a signal). Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function.

    “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

    “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.

  • Skill levelSkill level petitioner adoptedDecided for patent owner

    “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. Cir. 1995) (citation omitted). The level of ordinary skill in the art is also reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). For purposes of this Decision and with the exception of the qualifier “at least” with respect to experience which renders the level of ordinary skill in the art ambiguous and may encompass levels beyond ordinary, we adopt the assessment offered by Petitioner as it is consistent with the ’608 patent and the asserted prior art.” slip op. at 9

    “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

    “(1) the issue is identical to one decided in the first action; (2) the issue was actually litigated in the first action; (3) resolution of the issue was essential to a final judgment in the first action; and (4) [the party against whom collateral estoppel is being asserted] had a full and fair opportunity to litigate the issue in the first action. 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

    “II. ANALYSIS A. LEVEL OF ORDINARY SKILL Petitioner defines the person of ordinary skill in the art as follows: As of February 2006, a person of ordinary skill in the art (“POSITA”) would have been a person with a degree in 1 The Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), amended 35 U.S.C. § 103. Because the challenged claims of the ’414 patent have an effective filing date before the effective date of the applicable AIA amendments, we refer to the pre-AIA version of 35 U.S.C. § 103 throughout this Decision. 2 Mauer et al., U.S. Patent No. 7,395,085 B1, issued July 1, 2008 (Ex. 1005, “Mauer”). 3 Waylett et al., U.S. Patent No. 8,184,603 B2, issued May 22, 2012 (Ex. 1006, “Waylett”). computer science, electrical or computer engineering, physics, or a similar discipline . . . [and] would also have at least two years of relevant experience including, for example, work related to telecommunications networks. Pet. 3 (citing Ex. 1003 ¶ 54). The institution decision adopted Petitioner’s definition of a person having ordinary skill in the art. Dec. on Inst. 11–12. Patent Owner applied this definition for its response. Resp. 19. Petitioner’s undisputed definition of a person of ordinary skill in the art is reasonable and consistent with the prior art and ’414 patent specification. Based on the record before us, we adopt Petitioner’s undisputed proposal. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

But we do not need to construe “distributed mobile architecture (DMA)” to resolve this inter partes review. We thus do not construe this claim term. We also do not discern a need to construe explicitly any other claim language because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

    “a) Combination of Mauer and Waylett In support of both Ground 1 and Ground 2, Petitioner argues that a person of ordinary skill in the art would have been motivated to combine Mauer’s and Waylett’s disclosures, “using Waylett’s Network-in-a-box 224 in each of Mauer’s WWAN 14 and WLAN 12, resulting in at least two DMA systems.” Pet. 11–13. Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id. Citing similarities in Mauer’s and Waylett’s systems, Petitioner argues that “a POSITA would have been able to modify Mauer’s WWAN 14 and WLAN 12 networks so that each network uses Waylett’s NIB 224.” Id. at 14. According to Petitioner, the combination would have included a number of beneficial features from Mauer. Id. at 14–15. Petitioner further advances three reasons that a person of ordinary skill would have had to combine the references’ teaching. Id. at 15–16. First, asserting that Waylett discloses cost benefits and Mauer discloses “an improved method and system for notifying mobile stations,” Petitioner contends the “references each provide reasoning” to combine their disclosures. Id. at 15. Second, Petitioner argues that a person of ordinary skill in the art would have been motivated to “improve Mauer’s distributed wireless network system by consolidating it into a single box, making it compact in design allowing for faster deployment.” Id. at 16. “Third, Waylett’s NIB would help mitigate the shared concern of Mauer—that is, reaching a mobile station as it roams or moves outside of the service or coverage area.” Id.” slip op. at 24

    “Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56. In particular, as we explain above, claim 1 requires making use of the DPR after first determining the second mobile subscriber is not located within a first wireless coverage area based on HLR and VLR information and also determining that the second mobile subscriber is not located within a second wireless coverage area based on certain CLR information. The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information). See PO Sur-Reply 8–9; Ex. 2001 ¶¶ 111–113. For the reasons above, Petitioner does not establish by a preponderance of the evidence that the combined art teaches or suggests the final “when” recitation of claim 1.” slip op. at 29

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningTerm construed patent owner constructionDecided for patent owner

    “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

    “the battery power thresholds between (1) high and normal sensitivity positioning modes and (2) normal sensitivity positioning mode and turning off power to the GPS receiver) and Sakamoto’s two GPS signal level thresholds (i.e., K1 and K2) for teaching “the power level comprising a multitude of threshold values.” Pet. 50–51; Pet. 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. Thus, we determine Petitioner has not shown by a preponderance of the evidence that the subject matter of claims 10, 13, and 15 would have been obvious over Sakamoto.” slip op. at 31

    “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.

As discussed by Patent Owner, Dr. Subramanian conceded that there were multiple ways a person of ordinary skill in the art could add selftesting to Ellsberry. See PO Resp. 57 (citing Ex. 2004 ¶¶ 46, 47, 128, 129, 146; Ex. 2005, 121–125).

See Ex. 2004 ¶ 129; Ex. 2005, 121–125, 184–185. Dr. Brogioli credibly testifies that these alternative designs would have been more similar to what was seen in the prior art. Ex. 2004 ¶¶ 46, 47, 128, 129, 146.

    “combination, but Dr. Subramanian’s testimony is unavailing because it essentially repeats what is stated in the Petition, and states that Ellsberry and Jeddeloh “employ known signaling and testing techniques found in many prior art systems,” and combining Ellsberry and Jeddeloh “would therefore have been well within a Skilled Artisans’s abilities, would not have resulted in any unpredictable results and could have been readily accomplished without undue experimentation and with a reasonable expectation of success.” Pet. 32 (citing Ex. 1003 ¶¶ 146–147). We find this testimony to be conclusory, at a minimum, particularly in light of the relatively low level of skill in the art advanced by Petitioner. Further, as discussed below, Dr. Subramanian’s testimony is misguided. We find more persuasive Patent Owner’s contentions that “[p]ortions of Jeddeloh’s self-test module cannot be disassembled and distributed across Ellsberry’s memory module as proposed by Petitioner without creating new pathways or changing how existing components work, which creates timing issues and issues synchronizing the various signals sent to and received from the memory devices.” PO Resp. 62–63 (citing Ex. 2004 ¶ 83). For example, Dr. Brogioli explains that “two new circuits have been created using components disclosed in Jeddeloh and deployed to a distributed, and markedly different architecture than Jeddeloh. Not only are new pathways required within Ellsberry’s architecture that are not contemplated by Jeddeloh, but these pathways in some instances require being bidirectional.” Ex. 2004 ¶ 83.
