Petitioner presents a similar formulation. Pet. 10. Although we do not discern any meaningful distinction between the parties’ formulations, we adopt Patent Owner’s description of a person of ordinary skill as it is consistent with the prior art and challenged patent’s specification.

“a first current through one or more output ports of the at least one output port in a first operating mode,” and “is configured to output a second current capable of starting a vehicle engine through the pair of output terminals in a second operating mode.” Ex. 1001, 8:25–34. Claim 21 has similar first and second operating-mode limitations. Id. at 9:40–46. Patent Owner proposes that “[t]he proper construction for ‘first operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a first current through one or more output ports of the at least one output port, and outputting a second current capable of starting a vehicle engine through the pair of output terminals is inhibited.’” PO Resp. 25. Similarly, Patent Owner argues “[t]he proper construction for ‘second operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a second current capable of starting a vehicle engine through the pair of output terminals, and outputting a first current through one or more output ports of the at least one output port is inhibited.’” Id. at 27. Patent Owner asserts that claim differentiation supports its construction because dependent claim 3 recites “a third operating mode for outputting the first current and the second current simultaneously,” and “if the battery pack could output the first current and the second current simultaneously in the first operating mode, then there would be no difference between the claimed first operating mode and the claimed third operating mode.” Id. at 26. We disagree with Patent Owner’s constructions because, as Petitioner explains, they wrongly import current-inhibiting limitations beyond the plain language in the claim. Pet. Reply 1. Nothing in the at-issue language addresses inhibiting current. In addition, the claimed first and third operating modes are still distinct without importing additional limitations because outputting just the first current is sufficient for the first operating mode, but not for the third. In other words, whereas the third operating mode requires simultaneity, the first and second merely permit it. Thus, claim differentiation does not support Patent Owner’s construction. Last, although Patent Owner asserts that its construction “is consistent with the specification,” nothing in the cited passages describes inhibiting current. Prelim. Resp. 26 (citing Ex. 1001, 4:30–33, 5:30–33, 5:58–62). Instead, the specification characterizes the modes solely by what the portable charger “can output,” not what is inhibited. Ex. 1001, 4:30–33, 5:30–33, 5:58–62. Thus, we decline to read the first and second operating modes to require the current-inhibiting features that Patent Owner asserts.” slip op. at 6

“Patent Owner argues the two current paths are not different because Chen’s Figure 1 shows they overlap between the lithium battery and the output control circuit and “only diverge when making the connection to the output control circuit.” PO Resp. 32. We disagree. First, Patent Owner’s argument is based on a claim construction for “different” current paths that we do not adopt for the reasons above. In addition, we agree with Petitioner that Chen shows the claimed different current paths even under Patent Owner’s construction. Pet. Reply 8–12. Specifically, as Petitioner explains, a skilled artisan would recognize that Chen’s physical circuits are depicted in Figures 4–7, rather than in Chen’s Figure 1, which is merely a “block diagram of the principle of present invention.” Id. at 9; Ex. 1006 ¶ 15. Unlike Figure 1, Chen’s Figures 5, 6, and 7 show current paths between the battery and USB outputs, and between the battery and DC multi-gear output, that do not overlap with the high current path shown in Chen’s Figure 4. Pet. 9–12. Based on Petitioner’s analysis and for the reasons above, we agree with Petitioner that Chen teaches the claimed “pair of output terminals coupled to the battery pack and having a current path to the battery pack different from that of the at least one output port to the battery pack.”” slip op. at 10

“Patent Owner asserts one skilled in the art would not have added White’s fuse to Chen because doing so was “unnecessary” given Chen’s built-in relay K1 that already provides protection. PO Resp. 42–43. We disagree because, as Petitioner notes, “the Petition cited ample evidence that both layers of over current prevention provide improved safety and protection to the battery.” Pet. Reply 17 (citing Pet. 31–33); see also, e.g., Pet. 31 (describing “advantageously reduc[ing] the likelihood of damage”), id. at 32 (describing “the additional benefit of a safety fuse along a jumper cable to promptly cut off current in the event of a short circuit” and “more simplified maintenance and repair”). Given Petitioner’s unrebutted rationale, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that adding White’s fuse and polarity-protection connector to Chen’s power-supply system would have been obvious to one of ordinary skill in the art. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Other than the arguments addressed above, Patent Owner does not additionally challenge Petitioner’s obviousness showing based on Chen and White. We have reviewed Petitioner’s arguments and evidence and, based on that analysis, we find Petitioner has shown by a preponderance of the evidence that claims 1, 2, 6–9, 11–14, 16–22, 25–28, and 30–33 would have been obvious over Chen and White.” slip op. at 15

“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding.

“Petitioner contends “no formal claim construction is necessary in this proceeding.” Pet. 10; Reply 1, 4. Patent Owner contends the terms “mesh layer” and “coefficient of friction” require construction. Prelim. Resp. 14–16; Sur-reply 2–5. We have considered the parties’ arguments and discuss them below with regard to each of the terms Patent Owner contends should be construed. Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

As we explain in Section III(G), infra, Petitioner’s challenges to the ’227 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak. Given the strength of Petitioner’s challenges on the present record, this is not a situation where we would say that “reasonable minds can disagree regarding the purported treatment of the art,” and we therefore determine that the Examiner erred by not considering the art in substantially the combination Petitioner proposes.

“At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments. Patent Owner does not cite to evidence, such as expert testimony, to support its implied argument that Olson’s measured current is “fundamentally different” from the current received by the primary coil. See Prelim. Resp. 31–32. Petitioner’s declarant, Dr. Woods, on the other hand, testifies, inter alia, that “[t]he ‘[c]urrent measured by current measure block 226 is used in the calculation of power, which as depicted in FIG. 14, measures the ‘power in’ provided to transmit block 214/primary coil 54.” Ex. 1003 ¶ 37 (citing Ex. 1004 ¶¶ 74–75, Fig. 14) (first alteration added); see also, e.g., id. ¶ 42 (Dr. Woods testifying that the measured current to the power supply “is the current driving the external antenna 52, via the transmit block 214 and to the primary coil 54.” (citing Ex. 1004 ¶¶ 74–75, 112, Fig. 14)). Paragraph 75 of Olson, cited in support of that testimony, provides: “The power in is gauged by the power generated by charging unit 50 and is determined by multiplying the voltage of the internal voltage of charging unit 50, e.g., the voltage of a battery or batteries internal to charging unit 50, by the current driving external antenna 52.” Ex. 1004 ¶ 75 (emphasis added). We note that external antenna 52 includes primary coil 54. See, e.g., Fig. 14. Dr. Woods’ testimony is, at this stage, unrebutted. Patent Owner also argues that “Petitioner fails to provide any evidence regarding the function of Olson’s microprocessor 212 in relation to measuring input power,” and that, “[w]hile Olson describes a power calculation in paragraph [0075], Olson does not describe this power calculation as performed by microprocessor 212.” Prelim.

“Upon consideration of the parties’ arguments and for the reasons 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 for the following reasons. First, the construction of “grid point” we adopt here 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 represent an area of collected calibration data.”9 Ex. 1001, 3:57–67. 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 ’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.

“We agree with Petitioner. The pertinent disclosure from Shkedi reads: Simply stated, if a mobile telephone (at a user selected location) measures a plurality of service antenna signals and stores these with their respective service antenna identifications, then that mobile telephone (or an equivalent unit) upon observing an respective signal strengths—can reasonably conclude that it is within a predetermined proximity of the original user selected location. Ex. 1006, 8:41–48. Here, we find that the language “within a predetermined proximity of the original user selected location” refers to an area around the original user selected location. In other words, “within a predetermined proximity of the original user selected location” discloses that, instead of being exactly at the original user selected location, the mobile telephone only need be in the area or vicinity of the original user selected location. Indeed, in acknowledging “that Shkedi assumes the user is within some ‘predetermined’ distance of [the original user selected] location” (PO Resp. 33), Patent Owner effectively confirms this interpretation of Shkedi’s disclosure. That is, being within some predetermined distance of the original user selected location is equivalent to being within a circle centered on the original user selected location and having a radius equal to the predetermined distance. That Shkedi allegedly only “assumes” that the user is within the predetermined distance of the original user selected location does not detract from the fact that Shkedi’s disclosure of “within a predetermined proximity of the original user selected location” describes an area around the original user selected location.” slip op. at 34

“contention that, because the district court referred to the data points within an area being statistically similar as the defining characteristic of a NUG region, the claimed grid points cannot exist until after the calibration data is gathered and analyzed. See PO Resp. 18–19. This contention, even if correct, is not persuasive because it is generally improper to read limitations from specific embodiments into the claims. See Cadence Pharms. Inc. v.

Patent Owner’s assertion that the ’379 provisional application and the ’784 patent both describe evaluating the statistical similarities of calibration data (PO Resp. 10, 20) also fails to provide a sufficient reason to import a requirement to evaluate the calibration data into the construction of “grid point” or “non-uniform grid point.” Similarly, Patent Owner’s assertion that is “of great importance” because it is fundamental to generating the grid points is unpersuasive. See PO Resp. 27. Even describing evaluation as being “of great importance” is an insufficient basis for importing a requirement for evaluation. See Texas Instruments, Inc. v.

“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.

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.

“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

“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.

“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
