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

      “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.

The key difference between Petitioner’s and Patent Owner’s proposed qualifications for a person of ordinary skill at the time of the invention is that Patent Owner asserts that experience in “wireless networks, cellular radio systems, mobile communication devices and radio navigation systems,” 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.

      “We agree with Petitioner that Patent Owner’s proposed additional requirements of determining the boundaries of the area from an evaluation of calibration data should not be imported into the construction of “grid point.” See Pet. Reply 1, 5. The construction of “grid point” we adopt is supported by the disclosures of the ’753 patent. Patent Owner’s support and arguments for its proposed construction rely, in large part, on specific example methods of generating non-unform grid points (NUGs). See PO Resp. 27–32. We agree with Petitioner, however, that the intrinsic record supports that the term “grid point” encompasses both uniform and non-uniform grid points. See Pet. 8–13. The ’753 patent Specification identifies “grid points” as “NUGs or UGs” and further indicates that a “NUG” is a type of a grid point. Ex. 1001, 25:31–34, 26:32–35, 13:7–8 (“a grid point, such as a NUG”).

      “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. Pet. 35–36; Ex. 1004 ¶¶ 85, 105–117, 120, 123; Ex. 1003 ¶ 77; Pet. Reply 14–15; Ex. 1027 ¶¶ 44– 45. 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. Petitioner further asserts, and we agree, that Yost teaches collecting empirical measurements within the grid square surrounding the geographic point and averaging these measurements. 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.

      “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.

On this record, Patent Owner’s argument does not undermine Petitioner’s persuasive showing.
