      “III. ANALYSIS A. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art: would have been someone knowledgeable in wireless networks, cellular radio systems, mobile communication devices and radio navigation systems. That person would have at least a bachelor’s degree in electrical engineering, with a background in radio frequency communications and/or navigation system technology as well as approximately two years of industry experience working on radio communication and/or navigation systems. Pet. 18 (citing Ex. 1008 ¶ 44). Patent Owner adopts Petitioner’s asserted level of ordinary skill in the art. PO Resp. 13. 1 The Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112-29, 125 Stat. 284, 287–88 (2011), amended 35 U.S.C. §§ 102, 103, effective March 16, 2013. Because the application and provisional application for the ’753 patent were filed before this date, the pre-AIA version of §§ 102, 103 apply. See Ex. 1001, codes (22), (60). Petitioner does not dispute that the filing date of the provisional application filing date applies. See Pet. 6; see generally Pet. Reply. 2 US 2003/0064735 A1, published April 3, 2003 (Ex. 1006). 3 Ankur Agiwal, LOCATOR – Location Estimation System For Wireless LANs, WMASH 2004: Proceedings of the Second ACM International Workshop on Wireless Mobile Applications and Services on WLAN Hotspots, 102–109 (2004) (Ex. 1005). For the purposes of this Decision, we adopt the assessment offered by Petitioner as it is consistent with the ’753 patent and the prior art before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 7

      “The evidence supports that Petitioner has sufficiently demonstrated that Spain teaches “generating one or more sets of grid points for said calibration data,” as recited in limitation [1.2]. Spain states that: In another embodiment, the database is built by taking fingerprint measurements at predetermined locations and using intelligent algorithms that interpolate the fingerprints at all locations in between the sampled locations. Ex. 1006 ¶ 101. Relevant to this disclosure, Mr. Williams testifies that “Spain discloses generation of sets of grid points wherein each set includes newly interpolated grid points” because “the two grid points used to interpolate an additional grid point or points and the generated additional grid point or points are collectively a generated ‘set’ of grid points (i.e., a ‘set’ which includes the two calibrated grid points and the associated interpolated grid points).” Ex. 1008 ¶¶ 76–77 (citing Ex. 1006 ¶¶ 54, 55, 101). It is not disputed that Spain’s “fingerprints” are calibration data having characterizing parameters, such as observed signal strength, observed at calibration points. See Ex. 1006 ¶ 35. We find that this evidence demonstrates that Spain discloses generating one or more grid points, where the grid points are associated with calibration data.10 Accordingly, the evidence provides support that Spain’s interpolation of fingerprints at different locations discloses generation of one or more sets of grid points, where the grid points are associated with calibration data. Spain also discloses that: . . . the fingerprint corresponds not to one exact spot on the surface of the earth, but instead to a small area. The Lat and Long fields in this embodiment indicate a position inside the area, preferably the center point.” slip op. at 33

      “2. Discussion Petitioner refers to Agiwal to note that, like Spain, “Agiwal discloses an initial approximate location-based search of its database using live measurement data transmitted from a mobile device.” Pet. 18. Petitioner, however, relies only on Spain for its obviousness assertions. Id. at 22–38. The above discussion and Petitioner’s showing related to anticipation by Spain also equally apply to the obviousness showing over Spain as presented by Petitioner. See Connell v. Sears, Roebuck & Co., 722 F.2d 1542, 1548 (Fed. Cir. 1983). Patent Owner presents no additional arguments specifically directed to Petitioner’s showing as to obviousness under Spain that we have not already addressed. See generally PO Resp. Patent Owner also presents no evidence of objective indicia of nonobviousness. See generally PO Resp. Weighing the record as a whole in view of the findings and analysis above, we conclude that Petitioner has met its burden to show, by a preponderance of the evidence, that claims 1, 7, 9, 32, 38, and 40 would have been obvious over Spain as evidenced by Agiwal.” slip op. at 43

      “Here, Petitioner presents substantively identical challenges to claims 1–20 in the ’336 patent based on the same prior art, the same evidence, and the same unpatentability theories as Luminex presents in the Luminex IPR. Compare Pet. 15–89, with IPR2024-00101, Paper 1 (“Luminex Pet.”) at 15–89. According to Petitioner, the Petition differs from Luminex’s petition only because of different party names and updated sections concerning standing, related matters, real parties in interest, and counsel. Mot. 4. Because Petitioner presents substantively identical challenges to claims 1–20 in the ’336 patent based on the same prior art, the same evidence, and the same unpatentability theories as Luminex presents in the Luminex IPR, Petitioner satisfies the “reasonable likelihood” standard for instituting trial for the same reasons Luminex satisfied the “reasonable likelihood” standard for instituting trial.

    • Prior constructionPrior construction adoptedDecided for petitioner

      “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 ’494 patent. Namely, the ’494 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.”9 Ex. 1001, 3:58–4:2. The district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 1018, 3:50–60) as “provid[ing] a clear indication of the meaning of ‘grid point.’” Ex. 1028, 19 (emphasis added). We agree with the district court’s analysis. Although the ’494 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 words “non-uniform grid point,” a “non-uniform grid point” is a type of grid point. Furthermore, the district court construed “grid point” only, not “non-uniform grid point.” Id. at 18–20.” slip op. at 19

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “at the time the application was filed, we consider the level of ordinary skill in the pertinent art at the critical time. Graham, 383 U.S. at 17. The resolution of this question is important because it allows us to “maintain[] objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu–Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). In assessing 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) (quotation omitted). Generally, it is easier to establish obviousness under a higher level of ordinary skill in the art. Innovention Toys, LLC v. MGA Entm’t, Inc., 637 F.3d 1314, 1323 (Fed. Cir. 2011) (“A less sophisticated level of skill generally favors a determination of nonobviousness . . . while a higher level of skill favors the reverse.”). Petitioner contends that a person of ordinary skill in the art (POSITA) would have been someone knowledgeable in wireless networks, cellular radio systems, mobile communication devices and radio navigation systems, having at least a bachelor’s degree in electrical engineering, with a background in radio frequency communications and/or navigation system technology as well as approximately two years of industry experience working on radio communication and/or navigation systems. Pet. 13 (citing Ex. 1012 ¶ 30). Patent Owner does not dispute the level of ordinary skill in the art. PO Resp. 11–12. We adopt Petitioner’s proposal as reasonable and consistent with the ’494 patent specification and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “We also credit Mr. Williams’s testimony that determining which calibration data is representative of an area “would not require analysis” because “[i]t could be just the actual measurement,” and “analysis could be part of it, but it doesn’t have to be.” Ex. 2023, 37:10–22. Patent Owner’s argument that this testimony is not instructive because Mr. Williams limited his responses to the construction of calibration data and avoided responding to the question asked is not persuasive. See Sur-reply 8–9. Although Mr. Williams did refer to “the calibration data construction” in his response, we disagree that he avoided responding to the question asked. He was asked: “To determine which of that calibration data is representative of an area would require analyzing that set of collected calibration data, right?” and directly responded: “It would not require analysis. It could be just the actual measurement.” Ex. 2023, 37:10–16. This testimony responded to the question asked. He then stated: “I believe that is an issue as part of the calibration data construction,” before concluding: “So analysis could be part of it, but it doesn’t have to be.” Ex. 2023, 37:17–22. Merely expressing a belief that the issue or question asked relates to the calibration data construction does not equate to his response being limited to the calibration data construction.” slip op. at 23

      “Thus, “grid points” and “calibration points” in the ’494 patent are distinct elements that can overlap. Specifically, a “grid point” is a point associated with representative calibration data for an area, and a “calibration point” is a point at which calibration data is collected. These points can occupy the same physical location (i.e., the same longitude/latitude coordinates) but still be a “grid point” and a “calibration point.” For these reasons, we are not persuaded that the overlap between “grid points” and “calibration points” in Shkedi undermines Petitioner’s position and evidentiary showing. Petitioner, thus, has established by a preponderance of the evidence that Shkedi teaches each element of claim 4 including non-uniform grid points. We determine that the preponderance of the evidence establishes that claim 4 is anticipated by Shkedi.” slip op. at 42

PO Resp. passim. We note that, the District Court held, in a non-final order, that claims 1 and 12 were indefinite because of the term “in proximity.” Ex. 1028, 24– 28. The District Court, however, did not issue a final ruling with respect to claims 1 and 12 because the parties narrowed the dispute concerning the ’784 Patent to only claim 11. Ex. 2018, ¶ 3. We also note that we do not need to assess whether or not the term “in proximity” renders claims 1 and 12 indefinite to assess the Petition. Rather, we agree with Petitioner that the “in proximity” language is at least broad enough to “encompass” the matter set forth in Petitioner’s claim construction. See Pet. 17, 37–41. This is sufficient definition to make it logically possible to reach the merits of Petitioner’s challenge. See Intel Corp. v. Qualcomm Inc., 21 F.4th 801, 813 (Fed.

      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage.

      “constructions. First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery.

Ex. 2006 ¶ 119. In particular, Dr. Yao persuasively testifies that one of ordinary skill in the art would have believed that the charge cut-off voltage was no more than 4.2 V, and most likely equal to “about 4 V.” Id. ¶¶ 119–122. Petitioner argues that because the battery of Uemura is charged “to” a maximum voltage of 4.3 V, Uemura discloses the claimed charge cut-off voltage under either Petitioner’s or Patent Owner’s construction of the term. Pet. Reply 11–12 (citing Ex. 1009 ¶ 81; Ex. 1044 ¶¶ 56–59). This argument is not persuasive because Mr. Juzkow unambiguously testified that charging in Uemura stopped when the applied voltage reached 4.3 V, and Uemura discloses that the battery was charged “at” a voltage ranging from 4.3 V to 2.0 V, not “to” such a voltage.

See Pet. 40–42. In particular, Petitioner states that additing a foamed polymer tape to Yanagita’s separtor core material 2 would have been expected to improve the electrical perforamce of the cable by reducing the capitance between twisted pairs on one side of Yanagita’s separator and twisted pairs on the other side, thus reducing current leakage between them and reducing the transmission loss due to such leakage. Pet. 42 (citing Ex. 1007 ¶¶ 45, 139). Petitioner asserts that a POSITA would have been motivated to add a foamed polymer tape, such as Jachimowicz’s foamed polyethlyene tape to Yangida’s core, because it would have been expected to beneficially lower the dielectic contsant of the material between twisted pairs on either side of the separator due to the addition of low-dielectric constant foamed material.

      “To the extent Petitioner argues that Dr. Eldering does not meet the minimum qualifications of a POSITA, we disagree. First, our definition of a POSITA requires 3–4 years of industry experience for those holding only a bachelor’s degree and that less years of industry experience is required for those with additional education. Inst. Dec. 8–9. Dr. Eldering holds a Ph.D. in electrical industry and, thus, less than 3–4 years of industry experience is required. Moreover, Dr. Eldering’s declaration, testimony, and CV demonstrate that Dr. Eldering has many years of industry experience with twisted pair data cables.
