      “at least a four-year degree in electrical engineering, mechanical engineering, biomedical engineering, optical engineering, or related field of study, or equivalent experience, and at least two years’ experience in academia or industry studying or developing physiological monitoring devices such as non-invasive biosensors. Pet. 8 (citing Ex. 1002 ¶ 29). Petitioner also contends that a person of ordinary skill would have been “familiar with, e.g., sensor system design, including inertial and other motion 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. 25. 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 ’124 patent and the references cited in the Petition.” slip op. at 10

      “We need not reach the issue of whether the preamble is limiting for purposes of determining patentability of the challenged claims. Even were we to agree with Patent Owner that the preamble is limiting and the claims are limited to a finger-worn ring wearable computer device, Petitioner has relied on Schröder in each ground to disclose a “wearable computing device configured to be worn around a finger of a wearer.” Pet. 22 (Ground 1), 45 (Ground 2, relying on Yuen for adding the functionality of light sources with a photodetector, temperature sensors, and varying the sampling frequency of sensor data acquisition), 56 (Ground 3).

      “We are not persuaded by Petitioner’s arguments and find that Patent Owner has the better position for several reasons. First, the record supports Patent Owner’s argument that Mestas’s batteries are much too large to fit within a ring form factor, and “would have to be reduced in size on the 6 There is no Exhibit 2022 in the record of this case. magnitude of 5-10x from its current size to fit in a ring of Schröder.” Resp. 38 (citing Dr. Anthony’s cross-examination testimony at Ex. 2021, 313:12). Second, Petitioner relies on evidence in the Reply that Petitioner failed to specifically identify in the Petition. Compare Reply 3–5 (citing Ex. 1369 ¶¶ 7–14; Ex. 1079 ¶¶ 47, 71; Ex. 2022, 138:7–143:1; Ex. 1002 ¶¶ 96, 337; Ex. 2021, 12–13, 307:7–17; Ex. 2020, 212:6–214:13; Ex. 1081, 130:18–131:14; Ex. 1010 ¶ 168), 9 (referring back to Section § II.B.2) with Pet. 25–26 (citing Ex. 1002 ¶¶ 193–99; Ex. 1010 ¶¶ 157, 163, 168, 201, Fig. 6). More specifically, while the portion of Dr. Anthony’s Declaration cited in the Petition (see Pet. 25–26 (citing Ex. 1002 ¶¶ 193–99)) mentions the Technology Background Section V of his Declaration (Ex. 1002 ¶¶ 42–147), neither Petitioner nor Dr. Anthony sufficiently explains what evidence supports his opinion that it was feasible to incorporate batteries or battery-like devices into finger-rings, or how a person of ordinary skill in the art would have miniaturized a curved battery for incorporation into Schröder’s ring. Ex. 1002 ¶ 196 (describing that rechargeable batteries powering wearable electronic devices were “well-known by 2013” and “had also undergone significant advances in terms of miniaturization and energy density [that] made it feasible to incorporate batteries or battery-like devices such as supercapacitors into smaller form factors, such as finger rings, without sacrificing functionality” such as “lithium-polymer (Li-Po) batteries and solid-state batteries.”). Moreover, some of Petitioner’s citations in the Reply appear to be incorrect as there is no Exhibit 2022 of record in this case, as noted above. These issues undermine the strength of Petitioner’s showing by making it difficult to follow its reasoning, much less identify where in the record that reasoning finds support. See DeSilva v. DiLeonardi, 181 F.3d 865, 866–67 (7th Cir. 1999) (“A brief must make all arguments accessible to the judges, rather than ask them to play archaeologist with the record.”); United States v.

      “We credit Dr. Mercier’s testimony over Dr. Anthony’s and agree that Dr. Anthony’s testimony fails to account for the constraints of a substantially smaller form factor in Schröder’s finger-ring as compared to Mestas’s wrist device. Ex. 2018 ¶ 140. 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 ’124 patent, we also have evidence that prior art “finger ring wearables up to the ’124 patent had used ‘coin’ type batteries.” Resp. 40 (citing Ex. 2018 ¶ 140). We credit Dr. Mercier’s testimony that a person having ordinary skill in the art would have looked to a coin type battery for the necessary power requirements of Schröder’s device. Ex. 2018 ¶ 141. 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 patent), Fig. 24; Ex. 2018 ¶¶ 74–84. 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 ¶ 85. We also agree with Dr. Mercier that Dr. Anthony’s testimony lacks evidence or a technical analysis of the power requirements for the various sensors he suggests including in a wearable device and the capacity of the proposed GMBPow battery. See, e.g., Ex. 1002 ¶¶ 94, 210, 214–17; Ex. 2018 ¶ 97. Moreover, Dr. Anthony does not address the issues with the batteries that are identified in the references he discusses. For example, Dr. Anthony does not address Lee’s disclosure that “direct coating of electrode slurry onto plain paper led to the occasional internal-shorting of the device due to the leakage of the electrode material through a large-sized hole in the paper.” Ex. 1019, 2415. In contrast, Dr. Mercier discusses the pitfalls the skilled artisan faced in developing finger-ring devices. See, e.g., Ex. 2018 ¶¶ 77–79 (discussing the issues Rhee’s and Asada’s large rings), 83 (identifying power requirements as a design constraint). For example, Dr. Mercier explains that “flexible or curved batteries include flexible packaging materials such as aluminum laminated films that house the electrodes and electrolyte” such that “once the battery packaging is added to a battery such as GMBPow and then placed within a housing (e.g., external housing shell and internal potting), the resulting device would have dimensions that are not suitable for a finger-worn ring.” Id. ¶ 96 (citing Ex. 2026).” slip op. at 34

Resp. 12 (citing Ex. 2035 ¶¶ 38–39). According to Patent Owner, a person of ordinary skill in the art “would have at least a bachelor’s degree in a discipline related to mechanical engineering, physics, structural design, or an equivalent discipline, and at least two years of experience designing or analyzing rail cars.” Id.

Weighing the parties’ arguments and evidence, we find Petitioner provides sufficient rational underpinning for its assertion that it would have been obvious in view of Wong to implement a cross-wise extending beam to reinforce the 1946 Cyclopedia’s NSC ore car’s end slope sheet. Pet. 52–53; Prelim. Resp. 28– 30. In response to Petitioner’s assertion that “[t]he upper, outboard end of [Wong’s slope sheet 26] is reinforced by a cross-wise, L-shaped beam positioned under the slope sheet,” Patent Owner argues that “Wong does not provide reinforcement, but simply shows two sheets being connected for lading containment and load transfer.” Pet. 52; Prelim. Resp. 29. At this stage, we find Petitioner has the better position. Although we agree with Patent Owner that Wong shows two sheets connected to one another, that does not negate Petitioner’s correct observation that Wong shows an upper end of its end slope sheet 26 resting on an L-shaped structure, which apparently would reinforce end slope sheet.

For example, Wong’s disclosure of “hopper railcar 10” (Ex. 1006, 3:6–9) and the 1946 Cyclopedia’s disclosure of “Freight Cars: Hopper Ore” (Ex. 1004, 27–28; Ex. 1054, 27–28) support Petitioner’s position that “Wong and the 1946 Cyclopedia are in the same field.” Pet. 52; see also id. at 76 (“Wong discloses a rail road hopper car (‘hopper railcar’ 10)”), 18–19 (“The ore-car section of the 1946 Cyclopedia—entitled ‘Freight Cars: Hopper Ore’— contains drawings and a photograph of an ore car manufactured by Patent Owner NSC.”); Ex. 1003 ¶ 56 (“Wong and the 1946 Cyclopedia are in the same field of hopper railcars”) (citing Ex. 1004, 27–28; Ex. 1006, code [57]).

Petitioner argues that one of ordinary skill in the art at the time of the ’721 patent “would have a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with two years of experience designing or developing wireless networks, including long-term evolution LTE/4G and 5G new radio (NR) cellular technology.” Pet. 4 (citing Ex. 1003 ¶ 32). Petitioner adds that “[a]dditional education might substitute for some of the experience, and additional substantial experience might substitute for some of the educational background.” Id. at 4–5. Patent Owner at this stage of the proceeding does not provide an alternative definition for a level of skill in the art that one would have had at the time of the ’721 patent or identify any shortcoming in Petitioner’s formulation. See Prelim. Resp. 2. For purposes of this Decision on Institution, we adopt Petitioner’s definition of the level of skill for one of ordinary skill in the art. Pet. 4–5. We view the definition for the level of ordinary skill as consistent with the ’721 patent and the asserted prior art, and we apply it in our analysis below.” slip op. at 6

      “IV. PRINCIPLES OF LAW A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art. KSR Int’l Co. v. Teleflex, Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of non-obviousness, if present.5 See Graham, 383 U.S. at 17–18. When evaluating a claim for obviousness, we also must “determine whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed.

      “We have authority under 35 U.S.C. § 314 to determine whether to institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 584 U.S. 357, 363–66 (2018). Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a) (2024); see also PGS Geophysical AS v.

    • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

      “On the current record, we find that Petitioner has shown sufficiently that Cirik teaches the claimed “configuration parameters comprising first random access parameters, for beam failure recovery.” See Pet. 13– 17. Patent Owner argues that Petitioner fails to address this limitation, but we disagree. Prelim. Resp. 3. As we have set out above, Petitioner has provided a detailed mapping of what disclosures of Cirik (and Cirik’s provisional) on which it relies. Based on the current record, we see nothing incorrect in Petitioner identifying multiple parameters as making up the “configuration parameters comprising first random access parameters, for beam failure recovery.” As the plain language of claim 1 makes clear, there are “parameters”—plural—not just one. We also find, on the current record, that those “parameters” are not limited by the claim to only “random access parameters.” The disputed claim limitation uses the transitional phrase “comprising” in reciting the “configuration parameters comprising first random access parameters, for beam failure recovery.” As courts have explained, “[i]n the parlance of patent law, the transition ‘comprising’ creates a presumption that the recited elements are only a part of the device, that the claim does not exclude additional, unrecited elements.” Crystal Semiconductor Corp. v. TriTech Microelectronics Int’l, Inc., 246 F.3d 1336, 1348 (Fed. Cir. 2001). Claim 1 recites “configuration parameters comprising first random access parameters, for beam failure recovery.” Thus, we agree with Petitioner that the “configuration parameters comprising first random access parameters, for beam failure recovery,” can—but are not required to—include additional parameters (i.e., in addition to the recited “first random access parameters”). Here, we find that, on the current record, Petitioner has shown sufficiently Cirik’s “configuration parameters [that] may indicate the maximum number of beam of beam failure counter” are such parameters for beam failure recovery. Ex. 1005 ¶ 307; Ex. 1003 ¶ 52. As the Petition’s citations suggest, these are substantially the same as examples identified in the ’615 patent. See Pet. 15–16 (citing Ex. 1001, 63:18–23, 41:65–67; Ex. 1003 ¶ 56). Petitioner has further sufficiently shown that Cirik also discloses that as part of its beam failure recovery process, Cirik initiates certain “random access (RA) procedures.” Id. at 16 (citing Ex. 1005 ¶ 152, 161–164, Figs. 13A–C). As part of these RA procedures, we agree that Cirik discloses sending a configuration message including “one or more random access channel (RACH) parameters.” Id. (citing Ex. 1005 ¶¶ 151–154, 156, 161; Ex. 1003 ¶ 57). As Petitioner explains, “[t]he RACH parameters included in a configuration message can include indications of ‘one or more Physical RACH (PRACH) occasions available for transmission’ of a random-access preamble message and information for determining the power level of the transmission.” Id. (citing Ex. 1005 ¶¶ 153, 154). Cirik explains this “contention-free random access procedure . . . may be initiated for beam failure recovery.” Ex. 1005 ¶ 162; see also Pet. 20–23 (discussing in detail in the context of limitation [1b] the RA procedures for beam failure recovery in Cirik). We note that nothing in the claim language requires that the configuration parameters must be received in a single message. Thus, there is nothing improper about the Petitioner identifying multiple messages as including the “configuration parameters, comprising first random access parameters, for beam failure recovery” (i.e., Cirik’s configuration parameters that indicate the maximum number of beam failures and Cirik’s configuration parameters for random access processes used in connection with beam failure recovery), as Patent Owner suggests. Prelim. Resp. 4 (“But at no point does Petitioner assert that the configuration message for first random access parameters is included within the ‘one or more configuration parameters [that] indicate the maximum number of beam failures’ that it identifies for the ‘configuration parameters’ limitation.”). Accordingly, for purposes of institution, we find that Petitioner has shown sufficiently that Cirik discloses this limitation.” slip op. at 16
