    “Patent Owner does not persuade us to construe the term as “a value [or calculated value] that indicates how dire a patient’s symptoms are.” Patent Owner points to nothing in the intrinsic record that purportedly supports this construction, and we agree with Petitioner that “the patent specification’s disclosures regarding determining a level of symptom severity are broad, establishing that it can generally be derived from any sensor data and/or breathing events.” Pet. Reply 3–4; see also Ex. 1001, 3:44–46 (“Signals from the[] sensors are then analyzed to determine the level of severity of the symptoms of the subject’s sleep disorder.”). Patent Owner relies only on expert declarations to support its construction. But as indicated by the Federal Circuit, extrinsic evidence is “less significant than the intrinsic record in determining ‘the legally operative meaning of claim language.’” Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed. Cir. 2005). This is especially applicable here, where neither Dr. D’Ambrosio’s nor Dr. Schwartz’s declaration was prepared for this proceeding, and neither declarant was subject to cross examination on their opinions. Moreover, neither of the declarants was opining on claim construction; rather, they were addressing indefiniteness and/or written description issues. See Ex. 1058 at 7 (heading addressing definiteness); Ex. 2026 at 18 (heading addressing written description). Further, Dr. Schwartz appears to have been making an argument about certain patent claims (not the challenged ’333 patent) based on Patent Owner’s own statements made during prosecution of a separate patent application. See Ex. 2026 ¶ 47 (“[T]he similar term used in the ’284 patent claims (‘data of severity of sleep disorder symptoms’) does not find written description support in the specification by a disclosure of the same statistics disclosed in Wright, because CleveMed argued those statistics are not related to severity of sleep disorder symptoms.” (emphasis added)). Patent Owner has not persuaded us that Dr. Schwartz’s testimony has direct applicability to the claim term at issue here. Dr. Borkholder’s testimony is likewise unpersuasive. Aside from citing Dr. D’Ambrosio’s and Dr. Schwartz’s declarations, Dr. Borkholder cites Exhibits 2027 and 2016. These exhibits discuss indices such as AHI and RDI that are used to assess the severity of a patient’s symptoms, but Patent Owner has not adequately explained how they bear on construction of the claim term at issue here, which is not addressed in these exhibits. Ex. 2022 ¶¶ 32–33. Accordingly, we accord Dr. Borkholder’s claim construction opinions little weight, because they are unsupported by reference to objective, corroborating evidence of record. See, e.g., Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations . . . may render the testimony of little probative value in a validity determination.”); Xerox Corp. v. Bytemark, IPR2022-00624, Paper 9, 15 (PTAB 2023) (precedential) (explaining that declaration testimony that “is conclusory and unsupported” and which “adds little to the conclusory assertion for which it is offered to support . . . is entitled to little weight”).” slip op. at 23

    “We find that Petitioner has the better argument. Tidal volume refers to “the volume of air that is inspired or expired during a respiratory cycle.” Ex. 2028, 13–14; PO Resp. 10. “[H]ypopnea events are defined as a reduction of ≥50 % or 74 % in tidal volume from baseline and apnea events as absence of tidal volume for at least 10s.” Ex. 2028, 13–14 (emphasis omitted). Toge teaches that a control unit analyzes collected data (e.g., the flow rate) and calculates tidal volume. Ex. 1044 (Toge) ¶¶ 34–38. The calculated tidal volume is “a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy” because it represents, e.g., the “level of airway obstruction the patient experiences during the sleep apnea treatment using the PAP device.” Pet. 15. As Dr. Chatterjee explains: Toge discloses that tidal volume Fp is a quantified level of data because Toge discloses that Fp is monitored with respect to threshold values (id., [0051]) and because Fp is a function of Ft, Fa, and Fb, which are quantitative values. Toge discloses that tidal volume Fp is severity data because Toge discloses that tidal volume is indicative of whether the patient’s breathing warrants “emergency measures” (id., [0039]) and whether to “send an alert” in “an emergency where the patient’s breathing has drastically weakened” (id., [0055]). . . . . Because Toge discloses determining tidal volume (determine a quantified level of severity data) based on Ft, Fa, and Fb (id., [0035]), which corresponds to the subject’s condition (subject’s sleep apnea symptoms) while using the device (during the therapy) (id., [0036], [0037]), Toge discloses determin[ing] a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy. Ex. 1005 (Chatterjee Decl.) ¶¶ 122–125. Patent Owner’s attempt to dismiss tidal volume as a mere “breathing metric” is unavailing. First, Petitioner correctly “notes that in the paragraph PO cites to in Dr. Schwartz’s declaration, he indicates that breathing metrics are a level of severity data.” Pet. Reply 8 (citing Ex. 2026 ¶ 46 (“standard sleep disordered breathing metrics” [ ] were well validated indicators of the type and severity of sleep disordered breathing”)). Second, Dr. Kirkness explains that tidal volume represents the level of airway obstruction, e.g., apnea “is the most severe form of reduction in airflow [and] the absence of airflow results in quantified tidal volume of zero milliliters per breath.” Ex. 1003 (Kirkness Decl.) ¶¶ 157, 159; see also PO Resp. 10–11 (Patent Owner recognizing that an apnea is defined as absence of tidal volume for at least 10 seconds). The calculated tidal volume thus indicates severity because it is used to adjust the PAP system, e.g., in the case of decreasing tidal volume, a medical professional can change the airflow settings “to counter/treat the more severe level of airway obstruction observed from the decreasing tidal volume.” Ex. 1003 (Kirkness Decl.) ¶ 158; Pet. 15–16; Ex. 1044 (Toge) ¶ 39.” slip op. at 26

    “1. “drill guide” and “fixation base” Petitioner contends that the claim terms “drill guide” and “fixation base” require construction “to resolve certain of the unpatentability grounds presented.” Pet. 13–14. In particular, Petitioner proposes that “drill guide” means “drill guide made from metal or metallic alloy without traditional plastic or acrylic,” and that “fixation base” means “fixation base made from metal, metallic alloy or other strong material without traditional plastic or acrylic.” Id. According to Petitioner, the Specification “teaches that the composition of the drill guide is ‘a metal or metallic alloy,’” and provides no other alternatives. Id. at 14 (citing Ex. 1001, 5:35–36). Petitioner similarly alleges that “fixation base” is described as “being fabricated from a metal, metal alloy, or other strong material,” and that “traditional plastic or acrylic” is excluded in light of disclosures in a provisional application. Id. at 21–24. According to Petitioner, its proposed constructions should be adopted “based on disclaimer of claim scope in the provisional application incorporated into the [’209] patent specification.” Id. at 14–24. Patent Owner contends that we need not address the constructions proposed by Petitioner because the issues addressed by Petitioner’s proposed constructions only concern allegations of unpatentability directed to claims 11 and 13, which Patent Owner disclaimed. Resp. 4–5; Disclaimer 1. In Reply, Petitioner argues that its proposed constructions are relevant to Patent Owner’s evidence of objective indicia of non-obviousness, including the alleged nexus. Reply 18–19 n.3. In light of our analysis below, because no determination in this Decision turns on whether we adopt Petitioner’s proposed constructions of “drill guide” and “fixation base,” we find that no express construction of these terms is required.

    “substitution of the word ‘enclose’ for the term ‘surround.’” Sur-reply 6. We noted in the Institution Decision that “construing the claim term ‘surround’ to mean ‘enclose’ does not further inform or clarify to a person of ordinary skill in the art what is encompassed by the claim limitation.” Dec. 15. We reach the same conclusion here on the full record and find no basis to rewrite the Challenged Claims to replace “surround” with “enclose.” To the extent Patent Owner can be understood to suggest that we import additional limitations into the claims based on the exemplary figures in the ’209 patent, we decline to do so. Regardless, given the recognition by the Parties that “surround” and “enclose” are synonymous, our determinations in this Decision would have been the same had we adopted Patent Owner’s proposed definition of “surround” to mean “enclose.” Further, with regard to the claim language “configured and dimensioned to surround at least a portion of the teeth of the patient,” Patent Owner proposes construing “a portion of the teeth” as “at least some teeth.” Resp. 9 (citing Ex. 2007 ¶ 44). Patent Owner, however, offers no sufficient explanation in its Response to explain how why a “portion of the teeth” means “at least some teeth.” The Specification does not provide an explicit definition of “a portion of the teeth” and does not suggest an intention to use a meaning of the term “a portion of the teeth” that is particular to the ’209 patent. To the extent Patent Owner can be understood to imply that we should import additional limitations into the Challenged Claims based on the exemplary figures in the ’209 patent, we decline to do so. For that reason, alone, we decline to adopt Patent Owner’s proposed construction.” slip op. at 17

In particular, Petitioner posits that a POSITA would have sought references for improving upon “Burfeind’s burdensome and imprecise manual participant selection process,” wherein Crowley is such a reference. Pet. 17–18 (citing Ex. 1005, Abstract, ¶¶ 4, 7–8, 45; Ex. 1003 ¶¶ 81–82). Petitioner contends that Crowley’s system provides numerous advantages, such as “enabling ‘spontaneous socializing’ and ‘convenient communication among friends,’” and “help[s] avoid the problem of friends who were out near each other, but never realized it until later.” Id. at 18–19 (citing Ex. 1005 ¶¶ 6, 35). According to Petitioner, “Crowley thus provides express motivation for implementing its location-based features in Burfeind.” Id. at 19 (citing Ex. 1003 ¶¶ 84–86). Petitioner further contends that a POSITA would have a reasonable expectation of success in implementing the features of Crowley in Burfeind. Pet. 19 (citing Ex. 1003 ¶ 89–92). In particular, a POSITA would have readily been able to adapt Crowley’s location-tracking features “to identify user locations for the purpose of inviting individuals who are located near the event location.” Id.

According to Petitioner, Burfeind and Crowley disclose similar systems for organizing meetings between individuals (id. at 22 (citing Ex. 1004, Abstract; Ex. 1005 ¶ 5)), and because Burfeind “already contemplates techniques for grouping individuals in order to more conveniently select those individuals,” a POSITA “would have thus readily been able to modify Burfeind to determine the event organizer’s contacts that are located proximate to selected event venue.” Id. at 21–22 (citing Ex. 1003 ¶¶ 89–92). Thus, according to Petitioner, the POSITA: would have understood that implementing Crowley’s techniques in Burfeind would merely amount to the use of a known technique (Crowley’s location-based messaging) to improve similar systems in the same way (enabling the system to automatically send messages/invitations to nearby individuals), as well as applying a known technique to a known system ready for improvement to yield predictable results.

    “iv. Claim 1 Conclusion Based on the complete record presented, Petitioner has shown that Gage teaches all limitations of claim 1. Thus, we determine that Petitioner has shown by a preponderance of the evidence that the subject matter of claim 1 would have been obvious over Gage. v. Independent claim 8 Independent claim 8 recites a method of “providing situation related information to a situation authority via a situational network,” wherein the method comprises “receiving, by a participant device, a roll call query soliciting a reply related to a status of a participant based on the participant being determined, by the situation authority, to be geographically proximate to the situation,” “receiving, by the participant device, a selection of a status response from the participant,” and “sending the status response to the central authority, wherein the status response is included in a roll call list.” Ex. 1001, 34:46–57. Petitioner generally refers to its contentions with respect to claim 1. Pet. 34–36. In particular, Petitioner contends that Gage teaches a subscriber device that communicates a status indicator to the disaster response system through a subscriber status reporting system that implements a “situational network” configured for use during disasters. Id. at 34 (citing Ex. 1005 ¶¶ 19, 25). Petitioner additionally contends that Gage’s “disaster response system” is a “situation authority” because the disaster response system detects an occurrence of a disaster affecting a region, receives and aggregates information related to the disaster, and then provides the information to various participants in the network. Id. (citing Ex. 1005 ¶¶ 8–9, 21, 36, 45; Ex. 1003 ¶ 104). With respect to the “situational network” limitation, Patent Owner” slip op. at 39

Mr. Reid further explains that “the skilled person would have known that adding currency exchange to a trading system would be a desired improvement.” Id. After reviewing the record, we determine that Petitioner has set forth a sufficient rationale for combining Sellberg’s teachings with Calo’s system. Sellberg discloses a trading system that utilizes an updated exchange rate that is repeatedly and automatically received from the currency market or the market maker, “and the last received updated exchange rate between the different currency and the specified currency at the time of receiving the order is used as the received current exchange rate.” Ex. 1019 ¶ 24. Mr. Reid has explained, with sufficient reasoning and citation to the record, how and why a POSITA would have added Sellberg’s currency exchange features to Calo’s trading system. Ex. 1002 ¶ 182.

    “Petitioner asserts that for the term “prevailing exchange rate,” as recited in claims 1, 2, 6, 9, and 10, “[t]he term prevailing commonly means ‘current.’” Pet. 28–29. According to Petitioner, this is consistent with the ’107 patent. Id. Petitioner asserts that “[t]he only rates the Specification describes using are a ‘forward’ rate or a ‘spot’ rate – in other words, a selected current exchange rate.” Id. at 29 (citing Ex. 1002 ¶ 34). Petitioner thus asserts that “‘prevailing exchange rate’ means ‘a selected current exchange rate that is not an FOREX average exchange rate.’” Id. Petitioner further contends that the term “prevailing currency exchange rate,” as recited in claims 2 and 9–11, “is the same as the prevailing exchange rate but limited specifically to currencies.” Id.

    “Rule 104(b) provides, in relevant part, that the Petition must contain an “[i]dentification of challenge” and “[p]rovide a statement of the precise relief requested for each claim challenged” that includes: (4) How the construed claim is unpatentable under the statutory grounds identified in paragraph (b)(2) of this section. The petition must specify where each element of the claim is found in the prior art patents or printed publications relied upon; and (5) The exhibit number of the supporting evidence relied upon to support the challenge and the relevance of the evidence to the challenge raised, including identifying specific portions of the evidence that support the challenge. The Board may exclude or give no weight to the evidence where a party has failed to state its relevance or to identify specific portions of the evidence that support the challenge. 37 C.F.R. § 42.104(b)(4)–(5) (2023) (emphasis added). Rule 22(a)(2) requires a petition to include “[a] full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence including material facts, and the governing law, rules, and precedent.” 37 C.F.R. § 42.22(a)(2) (2023). Based on the complete record, we determine that the Petition satisfies our rules and do not agree with Patent Owner that the Petition is deficient in this regard. For example, with respect to the obviousness challenge based on Calo, Rude, and Sellberg, the Petition provides a discussion on pages 41–43 with accompanying claim charts identifying where the prior art references disclose each limitation of the challenged claims (Pet. 51–75), and further cites to the supporting testimony of Mr. Reid for the motivation to combine the references (see, e.g., Ex. 1002 ¶ 338).
