    “We do not credit Dr. Anthony’s testimony, which is based on the arbitrary shading in Figure 7 (see Ex. 1002 ¶ 174), that Schröder teaches or suggests limitation 1[d] because it (1) is inconsistent with Petitioner’s reasoning for limitation 1[c], and (2) it is based on an admitted misreading of the embodiment of Schröder’s Figure 5 (see Ex. 1002 ¶ 175). As to the first item, Dr. Anthony states that “a POSITA would have been motivated to place a battery in a part of the cavity that is far from a PCB holding other electrical components because that configuration allows for better thermal management.” Ex. 1002, para. 175. The problem with this statement is that Petitioner relies on Schröder’s teaching that inlay 12, i.e., the alleged PCB, could include “other electrical components,” such as a battery to support its position that Schröder suggests placing a battery between the ring halves. See, e.g., Pet. Reply 2 (pointing to Dr. Mercier’s depo testimony that inlay 12 with “other components” is inserted between ring halves); id. at 3 (relying on Schröder’s teaching about placing components in depressions on inlay 12). So, Petitioner earlier asserts for the battery limitation 1[c] that Schröder teaches or suggests putting a battery on inlay 12 inside the ring halves, but then for limitation 1[d], Dr. Anthony testifies that a POSITA would place the battery “far” away from the inlay 12 (i.e., the alleged PCB). These positions are inconsistent.” slip op. at 25

Pet. 8 (citing Ex. 1002 ¶¶ 18–22). Petitioner also contends that a person of ordinary skill would have been “familiar with, for example, sensor system design and signal processing” and that “[a] higher level of education or skill might make up for less experience, and vice versa.” Id. Patent Owner agrees with Petitioner’s proposed definition of a person of ordinary skill in the art. Resp. 26. We adopt this uncontested definition of the level of ordinary skill in the art.

    “Patent Owner indicates that in the related ITC proceeding involving the ’178 patent, the Administrative Law Judge (ALJ) adopted three constructions agreed-upon by the parties in that proceeding8 and also construed two disputed terms.9 Resp. 26–27 (citing Ex. 2016, 5, 6, 14). Patent Owner agrees with Petitioner, however, that no terms need to be construed to decide the issues raised in the Petition. Id. at 27. We reviewed the constructions adopted by the ITC. Ex. 2016, 5, 6, 14. 8 In the ITC proceeding, the ALJ adopted the parties’ agreed-upon constructions that: (1) the preamble of claim 1 [a finger-worn wearable ring device] is limiting; (2) [positioned/configured to fit] within a “cavity” is [positioned/configured to fit] within a “hollow space”; and (3) [the internal housing component] “coupled with” [the external housing component] is [the internal housing component] “connected with” [the external housing component]. Ex. 2016, 5. 9 In the ITC proceeding, the ALJ construed the claims such that: (1) the internal and external housing components of claims 1, 12, and 17 enclose space and do not necessarily exclude potting material; and (2) “circumferential,” as recited in claims 1, 17, and 18, does not require a closed shape. Ex. 2016, 14, 17. These constructions are not germane to the issues we need to decide to resolve this proceeding. Thus, we agree that no explicit claim construction is necessary for this decision. To the extent the parties’ arguments raise any implicit issues of claim construction, we address those issues within the context in which they are raised in our analysis below.” slip op. at 11

    “The record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor, and “Mestas’s batteries, layout, and other components . . . would have to be scaled down 5 to 10 times to be appropriately sized for a finger worn ring.” Resp. 64 (internal quotation marks omitted) (citing Dr. Anthony’s cross-examination testimony at Ex. 2021, 313:12). Moreover, we do not credit Dr. Anthony’s testimony that miniaturization of the battery would have been “trivial to implement.” Ex. 1002 ¶ 242. Dr. Anthony admitted on cross-examination that it would not have been within the level of skill of a person having ordinary skill in the art to design a smaller version of Mestas’s battery, and that such a person would need to procure a battery of the appropriate size and specifications for implementation in a finger-ring from a battery manufacturer. Ex. 2021, 315:9–318:9. Yet Dr. Anthony had not ascertained, for purposes of his testimony, whether there was a battery available in 2013 that was appropriate to fit within the inlay space of the modified version of Schröder’s finger-ring that he and Petitioner allege would have been obvious to one of skill in the art at that time. Id. at 321:5–10. Further, we credit Dr. Mercier’s testimony that Dr. Anthony’s testimony fails to consider the differences in power requirements between Mestas and Schröder or to account for the constraints of such a substantially smaller form factor in Schröder’s finger-ring as compared to Mestas’s wrist device. Ex. 2018 ¶¶ 159–160. Although large curved batteries suitable for use in a wrist band or other larger wearable device, such as shown in Mestas, were known at the time of the ’178 patent, we also have evidence that prior art “finger ring wearables up to the ’178 patent had used ‘coin’ type batteries.” Id. at 66 (citing Ex. 2018 ¶ 161). We credit Dr. Mercier’s testimony that a person having ordinary skill in the art would look to a coin type battery for the necessary power requirements of Schröder’s device. Ex. 2018 ¶ 161. Indeed, this testimony is consistent with the other art of record that consistently shows the use of flat batteries in finger-ring devices, often stacked above and protruding from the general ring shape of the device. See, e.g., Ex. 1005 (Niwa), Figs. 22, 28; Ex. 2025 (Asada ’701 patent), Fig. 4; Ex. 1035 (Rhee), Figs. 7-1, 8-1, 8-2; Ex. 1037 (Asada article), Fig. 9; Ex. 1034 (Asada ’199 patent), Fig. 2; Ex. 1028 (Kimura), Fig. 24; Ex. 2018 ¶¶ 61–70. In fact, Oura’s first-generation ring design, released in 2015, used a Superbowl ring-type design, with the battery and other components mounted on top of the ring. Ex. 2034; Ex. 2018 ¶ 71. Based on these findings, Petitioner has not met its burden to show by a preponderance of the evidence that a person having ordinary skill in the art would have been led to modify Schröder’s finger-ring to place a curved battery between the internal and external housing components in light of the teachings in Mestas. Thus, Petitioner has not met its burden to show by a preponderance of the evidence that dependent claim 3 of the ’178 patent is unpatentable over Schröder and Mestas.” slip op. at 38

Petitioner also argues element 1.e is taught by Ideses’s “approaches to pruning insignificant features,” which Petitioner argues are “to selectively includ[e]/exclud[e] features based on whether a feature coefficient ‘is within a predetermined range’ as required” by element 1.e. Id. at 34 (citing, e.g., Ex. 1005 ¶¶ 107, 109–110). But all of the selection and pruning described in Ideses concerns the” slip op. at 22

    “Reading the ’791 provisional’s description of the hydraulic link in conjunction with Figure 2, one skilled in the art reasonably would have surmised that, in order for the trapped fluid within the cavity to act as a solid and transmit force, its thickness must remain unchanged, or, in the words of claim 1, be “substantially constant.” Indeed, according to the ’791 provisional, the fluid acts as a solid because O-ring seals and extremely small clearances between needle piston 72 and chamber cap 86 prevent the trapped fluid from flowing around the piston upon actuation of the force, which clearly supports that the thickness of the fluid must remain substantially constant. Those disclosures reasonably convey to one skilled in the art that the inventor had possession of the hydraulic link limitation of claim 1, including it having a substantially constant thickness, as of the ’791 provisional’s filing date. Likewise, we observe that claim 41 recites that the “hydraulic fluid acts as an incompressible solid so that movement caused by the actuation of said dimensionally responsive member is transmitted through said fluid layer.” Ex. 1001, 20:53–56 (emphases added).

We find, based on this description of the hydraulic link, with Figure 2, one skilled in the art reasonably would have surmised that, in order for the trapped fluid within the cavity to act as a solid and transmit force, it would act as an incompressible solid. Petitioner does not further dispute that the ’791 provisional discloses the remaining limitations of the challenged claims.

    “The hydraulic link 22 consists of a hydraulic cavity 84 formed by hydraulic chamber 28 and hydraulic chamber cap 86. The cavity 84 is filled with viscous fluid. Within the chamber 28 is located the hydraulic piston part 72 of the needle valve 15. The chamber 28 is fitted around the hydraulic piston 72. O-ring seals 90 are located in the hydraulic chamber cap 86 and in the bottom of the hydraulic chamber 28 to prevent the fluid from leaking out of the cavity 84. The diametrical clearance between the outside diameter of the hydraulic piston 72 and the inside diameter of the hydraulic chamber 28 is extremely small (on the order of 50 to 250 microns). The exact clearance is dependent on the viscosity of the chosen fluid. The hydraulic flow in this clearance . . . is very small. The hydraulic fluid . . . acts as a solid during fast motions, because there is little flow going around the needle piston. Because the actuation occurs suddenly (on the order of 200 μs), the hydraulic fluid between the hydraulic chamber 28 and the needle valve piston 72 does not have the time to flow around the piston 72. Instead, the trapped fluid acts as a solid and transmits the movement of the magnetostrictive material 40 to the needle valve 14, causing it to lift against the needle spring 16.

Summary Regarding Obviousness Challenge Because Patent Owner’s arguments and evidence persuasively rebut Petitioner’s assertion that the Ancestral Applications do not provide written description support for the challenged claims, Petitioner has not shown adequately that Babayoff ’529 is prior art to the challenged claims.

    “In response, Patent Owner objects that “Petitioners’ interpretation of the claims as requiring the use of unfiltered white light to determine depth data is plainly at odds with the claims themselves.” Prelim. Resp. 4. Patent Owner argues that “[t]his interpretation leads to a contradiction between the independent and dependent claims: the same light illuminating the intraoral structure would have to be simultaneously filtered (as recited in the dependent claims) and unfiltered (as Petitioners presume to be required by the independent claims).” Id. Patent Owner also suggests the possibility that the Petition’s arguments mean “the independent claims encompass using unfiltered white light to obtain depth data.” Id. at 7. We do understand the Petition’s arguments to mean that the independent claims encompass using unfiltered white light to illuminate an intraoral structure, not that the independent claims require using white light to illuminate an intraoral structure. And we agree with that understanding of the independent claims’ scope. Consistent with Patent Owner’s explanation, if we construed the independent claims to require using unfiltered white light to illuminate an intraoral structure, that would conflict directly with the dependent claims’ express requirement to use colored filters.” slip op. at 15
