      “Dr. Kanellakopoulos’s explanation that angular momentum is not inherent to an object, and its computation requires an arbitrary choice of a point of origin that has no physical meaning in the context of vehicle motion, also supports Patent Owner’s position. Id. ¶ 71 (citing Ex. 2004, 262). Accordingly, Patent Owner’s argument, that angular momentum cannot be used to detect a vehicle turning, is persuasive. Id. We also find persuasive, as Dr. Kanellakopoulos explains, that Petitioner’s argument regarding the figure on Kleppner 234 is based on misinterpretation of the vectors in that figure.

See Pet. Reply 11. This argument does not satisfy Petitioner’s burden to provide articulated reasoning with some rational underpinning to support the conclusion of obviousness. See KSR, 550 U.S. at 419 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Petitioner does not explain which teaching of Kleppner a person of ordinary skill would have selected and combined with their knowledge of a rotation vector to yield the method of claim 1, or explain why a person of ordinary skill would have recognized based on Kleppner that estimating the angle between a rotation vector and gravity vector could be used to detect a vehicle turning. Nor does Petitioner respond to Patent Owner’s assertion that Kleppner provides no rationale for estimating an angle of alignment between a rotation vector and gravity vector as a way of detecting a vehicle turning.

Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004).

      “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.

Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C.

Appendix A. Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

The Petition contains only a single sentence addressing the issue, without any citation to record evidence or declaration support. See Pet. 46. In addition, the assertion merely states the conclusion that a “PHOSITA would understand that there is a rational underpinning to combine the teachings of Goss and House as required under patent law because both are related to cat litter having similar characteristics.” Id. This assertion, at most, addresses the fact that Goss and House are in the same field or that they are analogous art, but does not explain why a PHOSITA would have been motivated to combine Goss and House. See id. In addition, the Petition lacks sufficient explanation of how Petitioner proposes to combine Goss and House. See Pet. 46–53. Instead, when Petitioner relies on House in this challenge, it appears to be a back-up argument in the event that we find Goss fails to disclose the limitation. Merely stating that Goss and House both disclose a limitation does not explain which aspects of House Petitioner proposes adding to Goss or what the resulting litter composition would look like. See id. The details of the resulting litter based on the combination of Goss and House matter here because it could impact whether all limitations of a given claim are satisfied by the combination. For example, Petitioner relies exclusively on specific examples from Goss for the 47% surface area limitation, but adding some aspects of House’s litter components to meet other limitations could undermine Petitioner’s reliance on Goss’s specific examples. The failure of the Petition to set forth a specific combination elides these issues. See Pet. 46–51. Petitioner’s Reply arguably addresses some of these concerns by providing a more fulsome motivation section, backed by new expert testimony, and specific litter examples based on Goss and various cellulose filler materials allegedly disclosed by House. See Pet. Reply 24–25 (citing Ex. 1013 ¶ 7); see also PO Sur-reply 18–22 (arguing that Petitioner’s Reply still fails to articulate an adequate motivation to combine).

      “Patent Owner makes a number of arguments, but we do not find them persuasive enough to undermine Petitioner’s showing based on Ms. Borgese’s analysis. Patent Owner’s primary argument stems from its assertion that the bulk densities vary depending on a number of variables and that Ms. Borgese bases her ranges on documents, the technical data sheets for FS-40 and the ’397 patent for BL(2), that have bulk densities that are not the “same” as the bulk densities for FS-40 and BL(2) in Goss due to the passage of time, differences in where the clay was mined, how the clay was processed, and how the bulk density was measured. See PO Resp. 18– 19, 21–33; PO Sur-reply 2, 5–9. We do not view Petitioner’s challenge as based on the premise that the FS-40 clay referenced in the technical data sheets and Blue Mountain clay in the ’397 patent are the exact same as the FS-40 and BL(2) clays in Goss, but instead the clays and their bulk densities are similar enough that they will fall within the bulk density ranges Petitioner uses in its calculations. See Pet. 21–23, 68; Pet. Reply 6–7, 10. As a result, Patent Owner’s repeated assertions that the clays or their properties are not the “same” or processed “exactly the same” fail to engage 5 Patent Owner suggests that Petitioner fails to meet the inherency standard because Ms. Borgese uses the term “potential” when describing the bulk density range of BL(2). See PO Resp. 32 (citing Ex. 1003 ¶ 117). We do not read Ms. Borgese’s opinion in the same manner. Instead, we read the reference to “the potential bulk density range of BL(2), 35–47 lbs/ft3” as referring to any bulk density within that range, not that there is only the mere potential that the bulk density may fall within that range. See Ex. 1003 ¶ 117. Petitioner’s argument that the bulk densities were at least similar, such that that they fall within the ranges Petitioner uses. See, e.g., PO Resp. 4, 21–24, 30–31; Ex. 2009 ¶¶ 97–98 (Dr. Johnston limiting opinion to whether the clays are the “same”). As an example, when asked about the potential differences in bulk density between Goss’s filing date in 1997 and the 1999 technical data sheet, Ms. Borgese states that “[b]entonite clays have not changed significantly in a period of two years.” Ex. 2008, 24:7–15; see also Ex. 1003 ¶¶ 202–203 (opining that “modest difference in particle-size distribution between FS-40 disclosed in Goss [and] . . . the FS-40 Information Sheet ’99 only minimally impacts the bulk density”). Given Ms. Borgese’s personal experience making animal litters and using bentonites, we view her testimony as credible absent some evidence that any differences in bulk density would fall outside the ranges she uses. Patent Owner provides no such evidence. Nearly all of Patent Owner’s evidence goes to whether the clays and bulk densities would be the exactly the “same” in Goss as in the sources that Ms. Borgese relies on, and do not address how similar the bulk densities would be and do not attempt to establish that there are bulk densities for Goss’s FS- 40 and BL(2) clays that would fall outside the ranges Ms. Borgese uses. In the rare instances where Patent Owner does argue that the bulk densities would not be similar, or would not fall within Dr. Borgese’s ranges, Patent Owner fails to cite any evidence to support the assertion.

Pet. 4–5; PO Resp. 14. That definition presumes “experience in animal litter process development” and “familiarity with the composition and chemistry of various clays used in animal litter (including sodium bentonite).” Pet. 4–5. We find Ms. Borgese’s education and first-hand experience in animal litter process development, including experience with bentonite, sufficient to testify credibly as to the known bulk densities of the bentonite clays at issue in the case. As to Goss’s FS-40 sodium bentonite clay made by Wyo-Ben, Ms. Borgese opines that the range of bulk density for the material in Goss is between 58–64 lb/ft3 based on Wyo-Ben’s own technical data sheets from 1999 and 2002, which “describe the same (or similar) FS-40 (‘sodium bentonite’) composition.” Ex. 1003 ¶¶ 82–83, 106, 117; Pet. 21–22, 35. Then, in an effort “to be conservative in [her] analysis,” Ms. Borgese uses a broader range of 55–65 lb/ft3 for Goss’s FS-40 in her calculations. Ex. 1003 ¶ 117. Even when pushing her assumptions in directions that would result in the lowest possible external surface area percent for sodium bentonite, all of the calculations across the full range of potential bulk densities still meet the 47% surface area limitation. Id. ¶¶ 117–122; Pet. 43–46. Based on our review of the arguments and evidence, we find Ms. Borgese’s testimony as to the range of Goss’s FS-40 bulk density credible and persuasive.” slip op. at 25

      “Although the Petition does state that a person of ordinary skill in the art “would understand the plain and ordinary meaning of a ‘recess’ to include ‘an indentation in a line or surface (as an alcove in a room),’” the Petition does not specify what else is “include[d]” in this term, nor does it specify that the plain and ordinary meaning of “recess” includes the entire interior of a housing. The Petition also does not invoke the Specification as demonstrating that the plain and ordinary meaning of “recess” includes the entire housing.13 Pet. 64 (emphasis added). Petitioner’s belated proposal also conflicts with the language of the claims themselves. Independent claim 1 recites “a rotor disposed within the inserter housing.” Ex. 1001, 43:42. Dependent claim 7 narrows claim 1 by reciting that “the housing comprises a recess in which the rotor is received.” Id. at 44:11–12. If the interior of the inserter housing and the recess could be one and the same as Petitioner proposes, there would be no need for claim 7, because it would not further limit claim 1. See 35 U.S.C. § 112(d) (“a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed”); see also Nazomi Commc’ns, Inc. v. Arm Holdings, PLC, 403 F.3d 1364, 1370 (Fed.

Accordingly, we decline Petitioner’s belated request to construe “recess” to include “an entire cavity of a housing or a cylinder.” 13 We acknowledge that Petitioner argued that the entire interior of Gravesen’s housing maps to the claimed “recess,” but this was in the context of comparing the prior art to the claim as construed. Indeed, Petitioner asserted that “the space within [Gravesen’s] housing is an alcove.” Pet. 64– 65 (emphasis added). In sum, Petitioner did not timely argue that the plain and ordinary meaning of the term “recess” includes an entire cavity of a housing or a cylinder.
