“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. This definition is supported by the record and consistent with the disclosure in the ’178 patent and the references cited in the Petition.” slip op. at 10

“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

Patent Owner does not argue that we should exercise discretion under 35 U.S.C. § 314(a) because Petitioner uses more than one petition to challenge the ’731 patent. challenges the alleged priority date of the ’731 patent (IPR2024-01489) (‘First Petition’) and the second petition assumes that the Patent Owner’s claimed priority date is valid, and addresses prior art references predating that priority date (IPR2024-01490) (‘Second Petition’).” Ex. 1019, 1.

“Level of Ordinary Skill in the Art At this stage of the proceeding, there is no dispute about the level of ordinary skill in the art. Based on the testimony of Petitioner’s declarant, we determine that a person of ordinary skill in the art (“POSITA”) would have had a four-year degree in electrical engineering, mechanical engineering, biomedical engineering, optical engineering, or related field of study, and two years of experience in academia or industry studying or developing physiological monitoring devices such as non-invasive biosensors. A POSITA would have been familiar with sensor system design and signal experience, and vice versa. Ex. 1002 ¶ 21.

The ’723 patent also describes that “[a]ngular position transducer 78 is mounted inside . . . protective can 90 . . . which is bolted to hinge bracket 28 via an upright holding arm 92” and that “trigger pin 94 projects upwardly from the top surface of pivot shaft 24 and cooperates with angular position transducer 78 to generate an angular position signal.” Id. at 12:28–33, Fig. 5.

“We find Patent Owner’s arguments persuasive, and the above testimony of its technical expert, Mr. Alberth, even more so.

“In determining 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.

Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’302 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan, we apply the level of skill set forth above, which is consistent with the testimony of Dr. Buehrer (Ex. 1003 ¶ 23), except that we omit the two instances of “at least” to remove the unbounded nature of the definition.” slip op. at 13

Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987). Moreover, “[b]ecause the hallmark of anticipation is prior invention, the prior art reference—in order to anticipate under 35 U.S.C. § 102—must not only disclose all elements of the claim within the four corners of the document, but must also disclose those elements ‘arranged as in the claim.’” Net MoneyIN, Inc. v.

“Patent Owner disagrees with Petitioner’s articulation of the level of ordinary skill in the art, but does not offer a definition of its own. Prelim. Resp. 5. According to Patent Owner, “[t]his Petition and related declaration propose two alternative levels of ordinary skill in the art, where the second alternative does not require any formal education or any experience in the field of oil or gas production.” Id. While Patent Owner disagrees with Petitioner’s characterization of the level of ordinary skill in the art, Patent Owner does not explain how a different level of skill is likely to alter Petitioner’s analysis. Instead, Patent Owner contends that it “applied Petitioner’s articulation and confirmed the analysis detailed below would not change based on disagreements over the level of ordinary skill in the art.” Id. (citing Ex. 2101 ¶¶ 16–17). 8 To the extent necessary, and for purposes of this Decision, we accept Petitioner’s statement on the level of skill in the art. See Daiichi Sankyo Co. v.

The prior art itself may be sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima, 261 F.3d at 1355 (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus.

“To satisfy the definiteness requirement of § 112(b), a patent’s claims must, when “viewed in light of the specification and prosecution history, inform those skilled in the art about the scope of the invention with reasonable certainty.” Nautilus, 572 U.S. at 910. We are not persuaded that the Petition shows that it is more likely than not that Petitioner would prevail in demonstrating that the term “blockchain mining devices,” as recited by independent claims 1 and 24, is indefinite. As an initial matter, we agree with Patent Owner that “Petitioner’s indefiniteness theory is flawed because its ‘alternative interpretations’ are of its incorrect claim construction rather than the claim language in view of the specification as required by Nautilus.” Prelim. Resp. 13. We find the Specification informs, with reasonable certainty, those skilled in the art about the meaning of the term “blockchain mining devices.” The 18 Specification informs us that “each blockchain mining device 12 may be composed of suitable components. The blockchain mining device 12 may have a network interface, such as network equipment 88, and one or a plurality of mining processors 92 (92A-92E for example).” Ex. 1001, 15:21–25. And, claim 1 recites that the “blockchain mining devices [are] connected to the generator” and “each have a mining processor and are connected to a network interface.” Id. at 19:59–62. Thus, reading the term “blockchain mining devices” in light of the language of the claim and the Specification, an ordinarily skilled artisan would have understood “blockchain mining devices” to mean a device composed of, for example, a network interface and one or more processors.

Some of the exhibits, such as Exhibits 2027 and 2028 (the as-filed grandparent and parent applications), should have already been included in the record. Patent Owner also violates our Rule 42.6(d), which states that “[a] document already in the record of the proceeding must not be filed again, not even as an exhibit or an appendix, without express Board authorization.” If we granted Petitioner’s motion, then Patent Owner’s citations to some documents already of record, and filed by Petitioner, would become meaningless and would deprive us of the ability to analyze documents already properly filed in view of the parties’ arguments. For the reasons above and on the facts of this proceeding, Petitioner does not satisfy its “burden of proof to establish that it is entitled to the requested relief.” 37 C.F.R. § 42.20(c).

Petitioner contends, in the alternative, that the ordinarily skilled artisan would have had “five years or more of experience in mechanical product design,” but Patent Owner alternatively contends that the ordinarily skilled artisan has “a college degree in a non-technical field and at least 3 years of experience in product development.” Pet. 11; PO Resp. 14 requires more years of experience than Patent Owner’s alternate person of ordinary skill in the art. See Pet. 11; PO Resp. 14. In view of the above, we see no reason to disturb our preliminary determination regarding the level of ordinary skill in the art. Thus, we maintain and reaffirm that one of ordinary skill in the art “would have had either (1) five years or more of experience in mechanical product design, or (2) a bachelor’s degree in Mechanical Engineering and one year or more of experience in mechanical product design.” Pet. 11 (citing Ex. 1025 ¶¶ 25– 27).

“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.

“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.
