“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. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13. And, for the reasons discussed herein, the charge cut-off voltage may be, but is not necessarily, the same as the applied voltage during charging. PO Resp. 20.” slip op. at 15

“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. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

“We find the ’212 Patent is directed to data for a particular user (see, e.g., ’212 Patent, Abstract). This conclusion is supported by the Specification. Indeed, all discussion in the ’212 patent is directed to a pedometer for use by and relying on data obtained from an individual user. Thus, the Specification suggests that the term “calibration” should be construed as a process that correlates a user’s stride rate and stride length. The Oral hearing confirms this conclusion. In the Oral Hearing, Petitioner’s counsel, Mr. Doshi, responded to a request to identify the calibration and the plurality of calibrations as follows: JUDGE STEPHENS: So what are you pointing at in the 212 patent as being [a] calibration and the plurality of calibrations? MR. DOSHI: That’s in column 5. So at column 5 it says that after a proper warm up the user completes a sample run or walk on the track at normal pace, et cetera, et cetera. So it's saying that here’s S1 and following completion of the first run, so here it’s saying you’re doing different walks at different speeds . . .where you're having the user walk at different walking speeds and measuring their step size as you do that (Trans. 21:1–10; see also Tr. 19:4–7) JUDGE ZADO: Okay. And then so taking that further then, I understand your argument to be that in the 212 patent the runner for the first sample S1 will run at one pace and that’s, according to Petitioner, that's one calibration and then the runner will run at a second pace for the S2 sample and that’s the second calibration, and then the runner will run at a third pace and then that's the S3 sample and then that's a third calibration? Is that Petitioner's argument? MR. DOSHI: Yes 13 (Tr. 22:4–11). Therefore, based on Petitioner’s statements at the Oral Hearing, the term “calibration” should be construed as the process of taking a sample that correlates step rate and step length for an individual.” slip op. at 13

“Patent Owner does not dispute the educational level or experiential aspects of Petitioner’s definition in its Response (see generally PO Resp.), 18 despite Patent Owner’s declarant, Dr. Caloyannides, opining that the level of ordinary skill would not be so limited as proposed by Mr. Blackadar: I note that although the qualifications Mr. Blackadar describes would qualify one as a PHOSITA in this case, I do not believe the definition of a PHOSITA here would be so limited. The technology of the ‘212 Patent implicates other fields, such as Sports Medicine, Exercise Science, and Physiology. I believe that a bachelor’s degree in one of these fields, or a similar field, with at least two years of practical experience working with pedometers and/or health or fitness trackers or sensors, or an advanced degree in one of these areas, could qualify one as a PHOSITA in this case (Ex. 2001 ¶ 26). Petitioner argues that Patent Owner’s definition of a person of ordinary skill in the art would mean a “[person having ordinary skill in the art] under Patent Owner’s definition would be more well-informed than Patent Owner’s own expert” (Pet. Reply. 2); however, we do not read Patent Owner’s assertion or Dr. Caloyannides’ testimony as suggested by Petitioner. Rather, we read Dr. Caloyannides’ testimony as expanding the fields of expertise. We do not observe a meaningful difference between the parties’ assessments of a person of ordinary skill in the art. We further note that either assessment appears consistent with the level of ordinary skill in the art at the time of the invention as reflected in the prior art in the instant proceeding (see Okajima, 261 F.3d at 1355). Our analysis in this Decision is supported by either assessment.

“Two separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved (In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004)). Here, Petitioner has persuaded us that Levi is from the same field of endeavor as the ’212 Patent –– pedometers that count the number of steps taken to calculate distance traveled (see Pet. 20). Specifically, although Levi adds a navigation feature, Levi is directed to a pedometer that, in pertinent part, adjusts step size according to step frequency in order to estimate distance traveled by a user (Levi, 6:6–43). Levi states “[t]he present invention for a ground speed/distance sensor is an improvement over a common hiker’s pedometer” and “[t]he present invention analyzes the frequency of a user’s footsteps to aid in the detection of future footsteps, and further to aid in determining the size of footsteps taken by the user” (Levi, Abstract, 2:57–60, 2:65–67). Similarly, the ’212 Patent is directed to a pedometer and specifically, a pedometer that calculates actual stride lengths of a user based on relative stride rates (’212 Patent, Abstract). Thus, both the ’212 Patent and Levi are from the same field of endeavor –– pedometers or devices that include or rely on pedometers. Furthermore, both Levi and the ’212 Patent are pertinent to the particular problem with which the inventor is involved –– accurate distance identification. 44 Patent Owner additionally argues “[t]he different problems addressed” slip op. at 44
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“A holding of obviousness can be based on a showing that “there was an apparent reason to combine the known elements in the fashion claimed” (KSR Int’l v. Teleflex, Inc., 550 U.S. 398, 418 (2007)). Such a showing requires some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness. . . . [H]owever, the analysis need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ. (id. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)) (internal quotation marks omitted)). As admitted by Patent Owner, an ordinarily skilled artisan would have known a user’s stride length could vary with stride rate at the time of invention (see PO Resp. 52). As noted by Petitioner, Levi discloses using a dynamic step size algorithm that “improve[s] the accuracy of distance 49 measurements of a human footstep sensor” (Pet. Reply 25 (citing Levi, 6:17–21)). We further credit Mr. Blackadar’s testimony that an ordinarily skilled artisan would have been motivated to improve Jimenez using Levi’s dynamic step size algorithm, to improve the calculated distances (Ex. 1005 ¶¶ 92). Indeed, we find that an ordinarily skilled artisan would have been motivated to combine the teachings of Jimenez and Levi to “monitor [ ] the distance traveled more accurately than prior pedometers that calculated distance based on average stride length” (Pet. 31 (citing Ex. 1005 ¶ 90), 32 (citing Ex. 1005 ¶ 92)). In particular, we find that, given it was known a user’s stride length could vary with stride rate, as admitted by Patent Owner (PO Resp. 52), an ordinarily skilled artisan would have been motivated to implement a data processor that accounted for this relationship, such as that described in Levi (Pet. 32–33 (citing Ex. 1005 ¶¶ 93–94)).” slip op. at 49
