      “appointment of new counsel for Petitioner and a motion to stay pending IPR(s) was denied without prejudice to being refiled once new counsel has appeared for Petitioner. Ex. 2030. In the Nevada litigation, iProov moved to stay the case pending IPR(s) in February 2025, but the court has not decided whether to grant the stay. Prelim. Resp. 57. We decline to speculate about how the district court might rule on any refiled motion to stay in the California litigation (or the pending motion to stay in the Nevada litigation).

      “contends indicate that iProov is a real party in interest to this proceeding. For example, Patent Owner points to the overlap in prior art references asserted in this Petition and the prior art references relied upon in the California and Nevada litigations. Prelim. Resp. 14–15, 18. Patent Owner also points to indemnity obligations between iProov and Petitioner. Id. at 15–16. And finally, Patent Owner emphasizes the benefit that iProov would get from this Petition. Id. at 17–18. Having reviewed these arguments and evidence of record we determine that, even in light of the issues raised by Patent Owner, Petitioner was not acting at the behest of iProov in filing this Petition and that iProov did not direct, control, or fund this Petition. Ex. 1049 ¶ 4 (counsel for Petitioner attesting that “iProov did not direct, control, or fund the Petitions. iProov did not work on the Petitions nor was it involved with the Petitions in any way.

      “Second, the key differences between Petitioner’s and Patent Owner’s proposed qualifications for a person of ordinary skill in the art at the time of the invention is that Patent Owner asserts “experience in wireless telecommunications and cellular technology is necessary,” as well as a background in radio frequency communications and/or navigation system technology with two years of industry experience working in the same, would be required. PO Resp. 22–23 (citing Ex. 2018 ¶ 46); see also id. 44– 45. The ’104 patent is directed to locating a wireless mobile device in a geographic region. Ex. 1001, 1:13–20; PO Resp. 44.

      “In this case, Patent Owner attempts to make much of Dr. Sundaresan’s statement that he had been informed of the qualifications of a person of ordinary skill in the art. See PO Resp. 41–43. Dr. Sundaresan’s testimony, however, set forth this understanding of the requisite level of skill in the art (Ex. 1003 ¶ 8). In his supplemental declaration, Dr. Sundaresan further testifies that: I agreed with this POSITA definition when preparing the Declaration, and I continue to hold the opinion that the POSITA definition is both correct and appropriate based on the disclosures of the ’104 patent and the prior art analyzed in the Declaration. Ex. 1055 ¶ 17. Dr. Sundaresan further testifies that “[i]f I did not agree with the POSITA definition, then it would not have been included in paragraph 8 of the Declaration.” Id. ¶ 18. Dr. Sundaresan’s inclusion of the definition of the level of ordinary skill in his original declaration indicates that he agrees with the definition, as confirmed by his cited subsequent testimony. We note that, even with Patent Owner’s arguments, the record is clear that Patent Owner was on notice of Petitioner’s proposed definition of the level of ordinary skill at the time of the Petition.

      “explained below, we agree with Petitioner that Patent Owner’s additional requirement of evaluating the calibration data to determine the boundaries of the area represented by a grid point should not be included in the construction of either “grid point” or “non-uniform grid point.” Instead, based on the full record, we discern no reason to alter our prior construction of “grid point” as “a point associated with representative calibration data for an area” and maintain that construction for this Final Written Decision. The construction of “grid point” we adopt is supported by the Specification of the ’104 patent. Namely, the ’104 patent discloses that “[i]n general, a non-uniform grid point (NUG) may represent the signal characteristics and/or calibration data over a given region,” and “NUGs represent an area of collected calibration data.”18 Ex. 1001, 3:50–60. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 2018, 3:56–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 2012, 19 (emphasis added). We agree with the district court’s analysis. Although the ’104 patent does not explain how a generic “grid point” might differ from the described “nonuniform grid point,” we do not find this distinction pertinent to construing “grid point” in this case because neither party raises this issue. Also, based on the claim wording “non-uniform grid point,” a “non-uniform grid point” is a type of grid point. See Pet. Reply 3 (explaining why that plain meaning supports Petitioner’s proposed construction). Furthermore, the district court construed “grid point” only, not “non-uniform grid point.” Ex. 2012, 18–20.” slip op. at 27

      “Under our current guidance, the filing of a Sotera-type stipulation is not conclusive, but remains “highly relevant” and will be considered “as part of [our] holistic analysis” here. See Guidance Memo. Whether Petitioner has other bases for invalidating the ’457 patent, such as the CarnoJet prior art product identified in the district court, is not a consideration here if such bases could not be asserted in this proceeding (and are not being used to argue over the asserted prior art here as a loop hole from the stipulation, of which there is no evidence).” slip op. at 15

Moreover, Petitioner’s asserted reason to combine the references is supported by the references’ disclosures: Best-2008 suggests filtration of its coolant is desirable, but provides no specific means for doing so; Osada teaches a way of filtering fluid from an open-top tank, similar to Best-2008’s.” slip op. at 42

      “A POSITA[12]in the field of the ’457 patent at the time of the earliest possible effective filing date (December 14, 2012) would have had Bachelor of Science degree in mechanical or chemical engineering and at least two years of experience relating to the design and/or implementation of fluid circulation systems involving application of fluid dynamics and heat transfer principles. Additional education may serve as a substitute for a lack of experience and vice versa. (Ex-1003- Dahm at ¶¶36-41, 63-70.) Pet. 18–19. Patent Owner applies this same definition. Prelim. Resp. 6–7. At this stage of the proceeding, we accept and use Petitioner’s proposed and unopposed definition of the ordinarily skilled artisan.

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

      “We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification describes only fingerprint creation outside the virtual machine monitor because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. See Sur-reply 1– 2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter. Last, Petitioner’s characterization of Patent Owner’s infringement allegations in the related district-court proceedings, even if correct, do not undermine the claim’s plain language.” slip op. at 9

Petitioner argues that the intrinsic record supports its position because “[n]owhere in the ’697 Patent is there any teaching or suggestion that a [virtual machine monitor] creates a fingerprint/signature indicative of attack activity,” and instead, “[t]he ’697 Patent teaches that its signature generation engine is separate from the [virtual machine monitor].” Reply 2 (citing Ex. 1001, 8:12–19).

      “The evidence supports that Petitioner has sufficiently demonstrated that Bhattacharya and Yost teach limitation [1b]. Bhattacharya discloses that empirical measurement of signal strengths are used to generate “expected signal-strength functions E(1,x,y,t), E(2,x,y,t), and E(3,x,y,t),” with a grid overlaid onto a geographic region where the center of each square represents a location. Ex. 1004 ¶¶ 106, 115–117; see also Pet. 35. Petitioner asserts, and we agree, that Bhattacharya discloses associating the expected signal-strength function with locations in a region, and that data is stored in the “Expected Signal-Strength Database.” Pet. 35–36 (citing Ex. 1004 ¶ 85). We also agree that this association of location (point) with calibration data (signal strength) is sufficient for the teaching of a “grid point,” which is disclosed by Bhattacharya.

We also agree that Bhattacharya teaches the generation of “grid points” by, at least, populating the Expected Signal-Strength Database with locations and expected signal strength data, which includes interpolating the locations between sampled locations. Ex. 1004 ¶¶ 85, 119, 120, 123; Ex. 1003 ¶¶ 77– 78; Ex. 1027 ¶ 45; see also Pet. 35–36; Pet. Reply 15–16.

Pet. 37 (citing Sections V.2–3; Ex. 1008, 7:28–44; Ex. 1003 ¶ 79). Further, because it is supported by the teachings of Bhattacharya and Yost, we credit Dr. Sundaresan’s testimony that a person of ordinary skill in the art would have found that Yost’s small areas of predetermined size are similar to the grids and grid points in Bhattacharya. Ex. 1003 ¶ 79; Ex. 1008, 7:50–51; Ex. 1004 ¶ 106, Fig. 6. Yost discloses that by averaging the empirical signal strengths the effects of fast fading can be removed (Ex. 1008, 7:50–56), so we also credit Dr. Sundaresan’s testimony in this regard on the advantages of averaging the multiple empirical measurements in a grid square (Ex. 1003 ¶ 80). Petitioner further asserts, and we agree, that a person of ordinary skill in the art would have found it obvious that expected signal-strength functions of {E(1,x,y,t), E(2,x,y,t), and E(3,x,y,t)} for a given grid point of Bhattacharya “may represent an average of calibration data from multiple locations within the grid square, and not simply represent the storage of the calibration data itself” in view of Yost because Petitioner’s assertion is supported by the evidence. Pet. 37–38 (citing Ex. 1008, 7:50–56; Ex. 1003 ¶ 80). Accordingly, we agree with Petitioner that the combination of Bhattacharya and Yost teaches that the average of the calibration data is “representative calibration data for an area.” See Pet. 37–38; Ex. 1003 ¶¶ 79–80; Pet. Reply 16; Ex. 1027 ¶ 46. Thus, we agree with Petitioner that the evidence of record supports that Bhattacharya and Yost teach generating sets of grid points for the calibration data, where the grid points are points associated with representative calibration data for an area.” slip op. at 40

      “The ’494 patent is directed to locating a wireless mobile device in a geographic region. Ex. 1001, 1:20–27; PO Resp. 45. Bhattacharya is directed to estimating the geographic location of a wireless terminal. Ex. 1005, code (57), ¶¶ 1, 13; PO Resp. 44–45. Spain is directed to a method for locating the concentration of mobile radio traffic in a coverage area. Ex. 1006, code (54), ¶¶ 1, 11; PO Resp. 45. We find that there is support in the ’494 patent and prior art consistent with Patent Owner’s assertion that the qualifications of a person of skill would include knowledge of radio navigation and mobile communications technology. Accordingly, we adopt Patent Owner’s proposed qualifications for a person of ordinary skill.” slip op. at 9

    • BurdenDecided for petitioner

      “Patent Owner, however, has not identified any language in the Petition that explicitly incorporates by reference Dr. Sundaresan’s testimony. See generally PO Resp.; PO Sur-Reply. Nevertheless, to the extent that the Petition purportedly incorporates by reference Dr. Sundaresan’s testimony, we do not find such incorporation sufficiently extensive to merit disregarding the testimony. Typically, an incorporation by reference is deemed improper in instances in which large portions of a declaration are incorporated—particularly where the incorporation serves to circumvent a word-count limit. See, e.g., Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 10 (PTAB Aug. 29, 2014) (informative). In this case, however, Dr. Sundaresan’s testimony describing the level of ordinary skill in the art is short. Ex. 1003 ¶ 8. The amount of testimony is not extensive and, thus, its purported incorporation into the Petition presents little or no imposition on Patent Owner or the Board.” slip op. at 12

      “In reply, Petitioner argues that “under any reasonable read of the Sundaresan Declaration, Dr. Sundaresan implied agreement with the POSITA definition based on its inclusion in a signed declaration.” Pet. Reply 15. We agree with Petitioner. Although Dr. Sundaresan does not state explicitly that the proposed definition of the ordinary skill in the art is his opinion, we are persuaded that the manner in which the definition is set forth in his declaration indicates that he agrees with the definition. Patent Owner attempts to make much of Dr. Sundaresan’s statement that he had been informed of the qualifications of a person of ordinary skill in the art. See PO Resp. 41–43. Dr. Sundaresan’s testimony, however, set forth this understanding of the requisite level of skill in the art (Ex. 1003 9 Dr. Sundaresan has a doctoral degree in electrical and computer engineering and has extensive experience in wireless communications. Ex. 1003 ¶¶ 75–78. Dr. Sundaresan also has experience with navigation and geolocation systems such as development of wireless tracking systems, as evidenced by his experience in companies such as NavigateIO Inc. Id. at ¶¶ 77–78. Patent Owner does not argue that Dr. Sundaresan fails to meet requirements for the level of qualifications of one of ordinary skill in the art under its proposed qualifications, which we adopt here. See generally PO Resp.; PO Sur-reply. Based on a review of his qualifications, we determine that Dr. Sundaresan qualifies as a person of ordinary skill at the time of the invention. ¶ 8). In his supplemental declaration, Dr. Sundaresan testifies: I agreed with this POSITA definition when preparing the Declaration, and I continue to hold the opinion that the POSITA definition is both correct and appropriate based on the disclosures of the ’358 patent and the prior art analyzed in the Declaration. Ex. 1055 ¶ 17. Dr. Sundaresan further testifies that “[i]f I did not agree with the POSITA definition, then it would not have been included [] in paragraph 8 of the Declaration.” Id. ¶ 18. Dr. Sundaresan’s inclusion of the definition of the level of ordinary skill in his original declaration indicates that he agrees with the definition, as confirmed by his cited subsequent testimony. We note that, even with Patent Owner’s arguments, the record is clear that Patent Owner was on notice of Petitioner’s proposed definition of the level of ordinary skill at the time of the Petition. Pet. 6; cf. Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1006 (Fed.

      “We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. Sur-reply 1–2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter. Sur-reply 1–2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Last, Petitioner’s characterization of Patent Owner’s infringement allegations in the related district-court proceedings, even if correct, do not undermine the claim’s plain language.” slip op. at 9

Patent Owner contends that Petitioner could have addressed all of the challenged claims in one petition. Id.

Considering the facts holistically, we determine the totality of the circumstances here supports Petitioner’s position that two petitions are warranted.

And the task of challenging those claims is complicated by the potential for Patent Owner to argue for a narrow construction of “association” in limitation 1(b).
