      “Relying on the testimony of Patent Owner’s declarant Dr. Singhose, Petitioner argues that a person of ordinary skill in the art “would have known a central straight path has less airflow resistance than a circuitous one.” Reply 22–23 (citing Ex. 1035, 127:15–128:9). But the same witness also testified that higher airflow resistance might be desirable and explained that providing more resistance to airflow might result in improved mixing. Ex. 1035, 21:21–22:12, 127:20–24, 170:10–14. In addition, Dr. Singhose testifies that the complicated design of the airflow passageway in Xia “serves important functions,” including “allow[ing] large droplets to be reabsorbed by the liquid-guiding mechanism,” allowing “excessive liquid in the airflow [to] condense,” and “prevent[ing] the chemical liquid from being sucked into the mouth.” Ex. 2022 ¶ 183 (citing Ex. 1004, 11, 13–14, 16). Although Petitioner’s declarant Dr. Sturges testifies that a straight airflow passageway “would provide improved, smoother air flow,” he does not provide any evidence supporting the view that the air flow would be improved. Ex. 1007 ¶ 118. We credit the testimony of Dr. Singhose that using a straight passageway in Xia would have been detrimental rather than beneficial. Ex. 2022 ¶ 183. Petitioner also argues that the inventors’ use of a straight path is evidence that the use of a straight passageway was “merely common-sense obviousness.” Reply 22–23. This is hindsight. Otsuka Pharm. Co. v. Sandoz, Inc., 678 F.3d 1280, 1296 (Fed. Cir. 2012) (“The inventor’s own path itself never leads to a conclusion of obviousness; that is hindsight.”). Moreover, it does not address the testimony of Dr. Singhose that the use of a complicated passageway like that in Xia had benefits not present in a straight central passageway.” slip op. at 29

      “B. Level of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art (“POSITA”) “would have had a mechanical or electrical engineering degree, industrial design degree, or a similar technical degree, or equivalent work experience, and 5 to 10 years of experience in electromechanical devices.” Pet. 10 (citing Ex. 1007 ¶ 16). Prior to institution, Patent Owner stated that, for “the limited purpose of this Preliminary Response,” it “does not challenge the definition of a POSITA set forth in the Petition.” Prelim. Resp. 9. We adopted Petitioner’s proposed definition in our Decision granting institution. During trial, neither party disputed this definition. Upon a complete record, we see no reason to change the adopted definition.” slip op. at 9

      “Patent Owner argues, however, that this presumption is overcome in the present case, and we agree. PO Resp. 28–32. We note that, although the claims require the first aperture to be “on the first end,” the claims still require that the “housing hav[e] a first aperture.” Thus, the issue is whether the aperture must be on the housing itself or part of the housing, as well as whether the aperture is on the first end of the housing. Although “having” and “includes” are used with respect to the solution holding medium to refer to elements located inside the housing, the specification of the ’881 patent suggests that the ends of the housing are part of the housing itself, rather than located inside the housing. First, “the first end . . . can be integrated into a single assembly as part of the housing.” Ex. 1001, 6:16–17. Second, “the housing . . . may comprise the cylindrical wall and two end-caps,” or “the housing . . . may comprise the cartridge wall and a single end-cap.” Id. at 3:55–59. The only figures of the ’881 patent that depict first end 206 show it at the end of the housing rather than located within the interior of housing 202. Id. at Figs. 2, 3. Moreover, there is no requirement to construe a claim term uniformly across multiple uses in the claims when doing so would be nonsensical. Microprocessor Enhancement Corp. v. Texas Instruments, Inc., 520 F.3d 1367, 1375 (Fed. Cir. 2008). Here, construing a first element that is recited as “having” or “includ[ing]” a second element always as encompassing not only second elements that are part of the first element, but also second elements that are located within the interior of the first element, would lead to nonsensical results. Claim 2 recites an airflow passageway “having a length having a circular cross section.” Ex. 1001, 17:59–60. It would be nonsensical to interpret this claim as encompassing an airflow passageway of non-circular cross section that contains another object that has a circular cross section, and neither party argues in favor of such a reading. Similarly, claim 16 recites an “airflow passageway having an interior having a uniform cross-sectional area,” and there is no reason to interpret this claim as encompassing an airflow passageway of non-uniform cross-sectional area that contains another object that itself has uniform cross-sectional area. Id. at 19:47–48. Thus, the claims do not use “having” or “includes” consistently to refer to elements located within the interior of an object; instead, they sometimes use these terms to refer to elements that are a part of an object. See Epcon Gas Sys., Inc. v. Bauer Compressors, Inc., 279 F.3d 1022, 1030–31 (Fed. Cir. 2002) (terms should be construed based on the context of how the terms are used in the claims).” slip op. at 13

      “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 ’358 patent. Namely, the ’358 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 district court identified the second quoted passage, which is identically recited in the ’104 patent (see Ex. 2018, 3:50–60) 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 ’358 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 4 (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 26

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.

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.

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.

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.

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.

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.

      “prosecution history of the ’698 patent for understanding the phrase “at least one number based on,” recited in claim 1. Pet. 6 (citing Ex. 1004, 166). Petitioner proposes that the plain meaning of this phrase was expressly described during prosecution of the application that became the ’698 patent, where the Applicant argued that [a]s the specification explains, the “number based on []” is intended to refer to the output of any “formula,” including but not limited to a difference formula, that serves as a comparison “metric” (including “logical comparisons, arithmetically threshold (rounded) logical comparisons, arithmetic, probabilistic, fuzzy logic, neural network enabled, [or] heuristic” [¶00561], or “determinations that are based on derivatives, mathematical normalizations, correlation functions, functions” [¶0139]).

Apart from this, where neither party proposes any particular construction or indicates disagreement as to the meaning of any claim language, we need not explicitly construe any claim terms at this stage of the proceeding.
