Pet. 27 (stating claims should receive their “plain and ordinary meaning”); PO Resp. 10 (stating that Petitioner’s challenges fail “under any reasonable construction”). In an inter partes review, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. [§] 282(b).” 37 C.F.R. § 42.100(b). Under this standard, the words of a claim generally are given their “ordinary and customary meaning,” which is the meaning the term would have to a person of ordinary skill at the time of the invention, in the context of the entire patent including the specification.

      “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

      “disorder symptoms” require a “quantitative” calculation or use of an algorithm, we also disagree. See PO Resp. 14–16. First, nothing in the language of the claims themselves describes or requires a “quantitative” calculation or an algorithm. See generally Ex. 1001, 23:6–26:59. To be sure, the ’029 patent discloses embodiments that use known algorithms to “quantify the level of severity of the subject’s sleeping disorder or symptoms.” See, e.g., id. at 20:16–19. But the Specification does not require an algorithm. The Specification also indicates that quantification is merely “preferable” (i.e., not required), and is merely one embodiment. See, e.g., id. at 19:8–12 (“The signals from the one or more sensors used in various embodiments of the present invention are preferably analyzed using a processor and software that can quantitatively estimate or determine the severity of the subject’s sleeping disorder or symptoms.”) (emphasis added), 4:51–59 (“Finally, in still another embodiment, the present invention includes a sleeping disorder treatment system comprising a device for diagnosing and creating a quantitative output of a level of severity of a subject’s sleeping disorder or symptoms . . . .”) (emphasis added); see also Reply 5–6 (citing Ex. 1001, 4:3–59 and 19:8–12 and stating that the ’029 patent lists “numerous embodiments where only one of seven include a quantitative assessment”). Elsewhere, the Specification more generally states that signals from sensors are “analyzed to determine the level of severity of the symptoms,” without specifying that such analysis must be “quantitative” or performed by an algorithm. See Ex. 1001, 3:41–44. In view of these disclosures, Patent Owner does not persuade us to adopt its narrowing claim construction. Indeed, our reviewing court has “repeatedly warned against confining the claims” to specific embodiments disclosed in the Specification. Phillips, 415 F.3d at 1323. Patent Owner’s reliance on a prior Board decision in PGR2024- 00012, which related to the parent of the ’029 patent, is unavailing. See PO Resp. 15–16. We agree with Petitioner that in the cited case, “[t]he Board made no findings about the meaning of the term calculating ‘the data of a severity of the sleep disorder symptoms of the subject’ for claim construction.” Reply 8. Indeed, neither party offered any claim construction, and the Board determined that no claim construction was necessary for purposes of that decision. See ResMed Corp., PGR2024- 00012, Paper 7 at 8. The page of the decision Patent Owner cites addresses written description support in the specification for the claims challenged in that PGR, not claim construction. See id. at 16. In any event, the cited decision is a decision on institution. The Board’s statements there are, by nature, preliminary findings and conclusions based on a preliminary record, and are not binding here. For at least the above reasons, Patent Owner does not persuade us to adopt its narrowing claim construction and we find that the term “data of a severity” does not need construction because the words of the term are clear on their face.” slip op. at 31

      “skilled artisan would have incorporated only portions of Mumford’s algorithm into Truitt’s PAP (i.e., only those portions related to “the detection of sleep disordered events” and not the portions of the algorithm related to “determin[ing] sleep stage”) comes too late because this argument was not in the Petition. See, e.g., Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1286–87 (Fed. Cir. 2017) (rejecting petitioner’s “attempts to cure the petition’s deficiencies in its subsequent briefing to the Board”). The Petition does not discuss modifying Mumford’s sleep efficacy algorithm before incorporating it into Truitt’s PAP device or incorporating only certain features of the algorithm. Indeed, the Petition and Dr. Kirkness rely on Mumford’s ability to detect sleep arousals when mapping Mumford to the claimed “data of a severity” and “index.” See Pet. 69–70; Ex. 1003 (Kirkness Decl.) ¶¶ 323–325. Mumford discloses that the mask electrodes detect arousals. See Ex. 1009 (Mumford) 2:4–10, 11:39–48. The same lack of disclosure plagues Petitioner’s belated Reply argument that Truitt’s ports 74 and 76 can incorporate electric sensing elements that would have functioned similar to Mumford’s electrodes. See Reply 22. The Petition did not mention ports 74 and 76 or otherwise suggest that a skilled artisan would have added functionality similar to Mumford’s electrodes to Truitt’s PAP, and we find that it is too late on Reply for Petitioner to posit this modification.” slip op. at 40

      “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 to Dr. Jafari’s opinions. His declaration was not prepared for this proceeding and thus Dr. Jafari was not subject to cross examination in this proceeding. See Reply 6 n.3. Moreover, Dr. Jafari was not opining on claim construction; rather, he was addressing the alleged indefiniteness. See Ex. 2020 (Jafari Decl.) 12 (heading addressing definiteness), ¶¶ 41–42, 46. Additionally, paragraphs 41–42 of Dr. Jafari’s declaration discuss claim terms phrases in a different patent (US 11,375,921), which explicitly include the terms “quantified” and “quantitative.” See Reply 6–7; Ex. 2020 (Jafari Decl.) ¶ 34. For at least these reasons, Patent Owner has not persuaded us that Dr. Jafari’s testimony is applicable here. Further, regarding the portion of Patent Owner’s proposed construction reciting “the degree of deviation from the baseline characteristics of a patient without sleep disorder symptoms,” Dr. Borkholder does not do his own analysis, but instead simply states that he “agree[s] with the litigation claim construction opinions of Dr. Jafari.” Ex. 2019 (Borkholder Decl.) ¶ 53. This is insufficient, and thus we do not credit Dr. Borkholder’s testimony regarding claim construction. We instead credit Dr. Kirkness’s statement that “[s]everity data is frequently calculated as the deviation from baseline characteristics of the patient himself, not a generic person ‘without sleep disorder symptoms.’” Ex. 1071 (Kirkness Reply Decl.) ¶ 13; Reply 9. As Dr. Kirkness explains, and Patent Owner does not dispute (see generally Sur-reply), “[t]he ‘baseline characteristics of a [generic] patient without sleep disorder symptoms’ would be irrelevant to any particular patient with their own unique breathing patterns and sleep disorder symptoms.” Ex. 1071 (Kirkness Reply Decl.) ¶ 13 (second alteration in original). For at least these reasons, we reject Patent Owner’s proposed claim construction.” slip op. at 30

      “C. Claim Construction We interpret claim terms using “the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). Under the principles set forth by the Federal Circuit, the “words of a claim ‘are generally given their ordinary and customary meaning,’” as would be understood by a person of ordinary skill in the art at the time of the invention.

      “images are three dimensional—let alone a technique that captures two images at different distances, compares the images for certain differences, and verifies three dimensionality based on those differences, as recited by the claim. Instead, Tanii describes a system that “corrects warp in which the perspective is exaggerated when an image is captured with the user’s face at close range.” Ex. 1007, code (57). In particular, Tanii recognizes the physical phenomenon of perspective distortion (fish-eye distortion) where “[i]f the image of the face of a person or the like is captured from a point that is relatively nearby, an image is obtained in which the perspective appears exaggerated,” i.e., the user image is warped or distorted.

      “distance from the user. Derakhshani teaches two different approaches: (1) focus-distance approach and (2) parallax approach. Petitioner acknowledges that the focus-distance approach does not expressly disclose capturing a second image at a second distance. Pet. 12 (distinguishing “focus distances” from “actual distances.”). This is because focus-distance, by definition, is not actual distance. Ex. 1005, 16:47–48 (“Focus distance is the distance from a sensor to a point in its field of view that is perfectly in focus.”) In Derakhshani’s focus-distance approach the camera stays the same distance from its subject—only the focus distance changes. Id. at 16:66–17:2 (“By comparing degree of focus for a landmark in images with different focus distances, the distance from the sensor to the landmark may be estimated.”) Derakhshani’s parallax approach also does not expressly disclose capturing a second image at a second distance. In the parallax approach the camera is rotated or slid about the user to create images with different perspectives. Derakhshani, 17:59–64 (“In some implementations, the sensor is moved about the subject during image capture to collect image data from different orientations relative to the subject. For example, a single camera may be rotated or slid slightly or multiple cameras at different positions may be used for image capture.”). Rotating a camera around a user does not change the distance of the camera from the user. At the hearing Petitioner, instead, focused specifically on the use of the word “slid” in Derakhshani as indicating that Derakhshani takes a second image at a second distance. Tr. 16:9–12 (“[Petitioner’s Counsel: . . . Dr. Daft is talking about some of the terms that Derakhshani is using. For example, the term slid and shown in the images, he talks about how slid refers to the different distances between the sensor and the user.”). We determine that it is more likely that the word “slid,” as used in the relevant portion of Derakhshani, further describes the rotation of the camera about the user. Derakhshani indicates as much by describing that both rotating and sliding the camera are examples of how the camera sensor is “moved about the subject during image capture.” Derakhshani, 17:60–61. Thus, sliding the camera does not necessarily disclose moving the camera to a second distance from the subject.” slip op. at 27
