      “understanding of a person of ordinary skill in the art (“POSITA”). In assessing 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. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). “[O]ne or more factors may predominate.” Id. Based on the testimony of Mr. Crevelt, we determine that a person of ordinary skill in the art would have had at least a bachelor’s degree in computer science or computer engineering, with at least three years of experience in game development. Pet. 14 (citing Ex. 1003 ¶¶ 62–65). Additional experience could substitute for less education, and additional education could likewise substitute for less experience. Id. We determine that the level of ordinary skill in the art adopted above is consistent with the level of technical understanding and competence reflected in the ’336 patent Specification and the asserted prior art references, based on our review of the record. Patent Owner states that “[f]or the purposes of this response, Patent Owner does not dispute Petitioners’ proposed level of skill, and under any level of skill a POSITA would not understand the asserted Grounds to raise any unpatentability issue,” and “this POR and supporting declarations apply Petitioner’s proposed level of skill.” PO Resp. 8. Thus, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’336 patent and the asserted prior art, and we apply it in our obviousness analysis below.” slip op. at 11

      “The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).

    • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportPriority date awardedDecided for patent owner

      “b) Walker Priority Date Under Dynamic Drinkware, the Petitioner is required to show that “the provisional application provides support for the claims of the patent or published application.” In re Riggs, 131 F.4th 1377, 1384 (Fed. Cir. 2025). Thus, Petitioner must show that (1) at least one claim of Walker is supported by its provisional (U.S. Provisional Application No. 60/378,289 (the “’289PROV”) and (2) the specific subject matter relied upon as prior art is supported by the ’289PROV. Id. Petitioner does provide a detailed explanation about how the ’289PROV supports claim 1 of Walker. See Reply 6–12. However, as Patent Owner argues, Petitioner fails to show that the ’298PROV provides support for the specific subject matter relied on in Walker. See Sur-Reply 3–8. Petitioner only explains how the ’298PROV discloses “predetermined criteria” but does not provide any other explanation for how the other subject matter relied on in Walker is supported by the ’298PROV. Thus, we find that Petitioner has failed to show that Walker is entitled a priority date before May 1, 2003. See Riggs, 131 F.3d at 1384 (noting while “a prior art patent or published application cannot be accorded the benefit of its provisional application’s filing date absent a showing that the provisional application provides support for the claims of the patent or published application,” the challenger must also show that “the specific portions of the patent specification identified and relied on” to demonstrate purported invalidity have written description support).” slip op. at 24

      “We find that Petitioner has failed to show by a preponderance of the evidence that Kelly teaches limitation 1[f]. As Patent Owner persuasively argues, “the game play events” of limitation 1[f] refers to “game play events” in limitation 1[d], but Petitioner does not map “the game play events” identified in limitation 1[d] to limitation 1[f]. In its Reply, Petitioner does not dispute Patent Owner’s assertion, but merely reiterates its arguments from the Petition. See Reply 23–24, 26. However, none of these arguments or evidence demonstrates that the “game play events” in limitation 1[f] are same the “game play events” that are allegedly stored in limitation 1[d]. Even if we accept Petitioner’s contention that it was not identifying button presses, but rather includes “game states and game events in the game process,” Petitioner provides no evidence or even arguments that what it has identified here relates to what it has identified for limitation 1[f]. See Pet. 25–26 (citing Ex. 1005, 25:23–24, 32:27–33, 40:33–45, 56:49–51). For these reasons, Petitioner has failed to show by a preponderance of the evidence that Kelly teaches or suggests limitation 1[f]. Accordingly, we find that Petitioner has failed to show that claim 1 would have been obvious over Kelly. 2. Claims 3–5, 12, 13, 18–20, 22, 24–26, 29, 42, 44–47, and 50 Claims 3–5, 12, 13, 18–20, 22, 24–26, 29, 42, 44–47, and 50 all depend from claim 1. See PO Resp. 16 (explaining that the arguments for independent claim 1 also apply to the dependent claims inherent the deficiencies asserted with respect to the independent claims). We find Patent Owner’s arguments availing, as explained above. Accordingly, we find that Petitioner has failed to show by a preponderance of the evidence that claims 3–5, 12, 13, 18–20, 22, 24–26, 29, 42, 44–47, and 50 would have been obvious over Kelly.” slip op. at 40

      “¶ 39). Petitioner further relies on Stokes to teach an average particle size that preferentially scatter blue . . . LED light as compared to yellow . . . light from the luminescent material.” Id. at 26–27 (citing Ex. 1108, 7:1–4). Petitioner argues that “a POSA would have been motivated to apply this principle to Krummacher, because it would increase the conversion of blue light to yellow light and improve the uniformity of the light source.” Id. at 27 (citing Ex. 1102 ¶ 237). Petitioner notes that “[c]onversion of blue light to yellow light is improved by maximizing the scattering of blue light.” Id. In addition, Petitioner asserts that “[u]niformity is improved by preferentially scattering the concentrated light from the blue-light LED chip instead of the disperse light emitted by the phosphor.” Id. at 28 (citing Ex. 1102 ¶ 237). Petitioner contends that “[a] POSA would have had a reasonable expectation of success applying this principle to Krummacher, because the relevant particle size range includes the range disclosed by Krummacher.” Id. Petitioner argues that “[a] POSA would have recognized selecting an average particle size as a design decision to be made based on a number of factors, including the light scattering properties of the particles, and well within the skill of the art.” Id. (citing Ex. 1102 ¶ 238). We find this explanation and the supporting testimony of Dr. Doolittle well-reasoned and supported and entitled to significant weight. Thus, we find that Petitioner has shown by a preponderance of the evidence that the combination of Krummacher and Stokes teaches limitation 1[c], and that a person of ordinary skill in the art would have been motivated to combine the references in the manner proposed.” slip op. at 40

      “Finally, we do not agree with Patent Owner that “quantum efficiency” would have dissuaded a person of ordinary skill from making the combination. PO Resp. 36–38. To begin with, “[i]t’s not necessary to show that a combination is the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021). Here, as demonstrated by, at least, Shimizu and Stokes, blue LEDs in this wavelength range were known to work as light sources for white-light LEDs. See Pet. 30–31. Additionally, we find persuasive Petitioner’s evidence that a person of ordinary skill in the art would not have been concerned solely with quantum efficiency, but also with overall luminous efficacy of a complete white LED package. Reply 9. As Dr. Schubert’s textbook explains, A fundamental drawback of UV pumped white LEDs is the energy loss (Stoke’s shift). The potential luminous efficacy of UV pumped white LED lamps is, therefore, markedly lower than that of white sources based on a blue LED exciting a yellow phosphor. Ex. 2014, 358–59; see also Ex. 1148, 87:5–88:4 (acknowledging Stokes shift). Thus, the evidence shows that, whatever gain in quantum efficiency a lower wavelength might offer, there were other drawbacks that a person of ordinary skill would have to balance. But “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.” Medichem, 437 F.3d at 1165. Indeed, Petitioner has shown several references—including, Shimizu and Stokes—that made this tradeoff. Moreover, “[o]bviousness does not require absolute predictability of success. . . . [A]ll that is required is a reasonable expectation of success.” In re O’Farrell, 853 F.2d 894, 903–04 (Fed. Cir. 1988). We find that the prior art of record demonstrates that a person of ordinary skill in the art at the time of the invention would have such an expectation in making the combination of Krummacher, Stokes, and Shimizu. Accordingly, we find that Petitioner has shown by a preponderance of the evidence that there would have been motivation to combine Krummacher, Stokes, and Shimizu with a reasonable expectation of success.” slip op. at 43

Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions.

      “E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight.

      “III. ANALYSIS LEVEL OF ORDINARY SKILL A. Petitioner explains the applicable level of skill in the art as follows: As of June 24, 2010, a person of ordinary skill in the art (POSITA) would be a person having a bachelor’s degree in computer science, computer engineering, or an equivalent, as well as two years of industry experience and who would have had a working knowledge of software security analysis, and dynamic malware analysis. Additional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education. Pet. 8 (Ex. 1003 ¶¶ 30–31). Patent Owner does not dispute Petitioner’s explanation of the level of skill in the art. See Ex. 2031 ¶¶ 15–16. We adopt Petitioner’s uncontested proposed level of ordinary skill in the art, which we find consistent with the level of ordinary skill in the art reflected by the ’872 patent and the prior art of record.

      “We begin with the claim language in view of the Specification, which weighs heavily against Patent Owner’s position that we should rewrite “computer system” as narrowly referring to a “computing device.” PO Resp. 24. As Petitioner notes, the ’872 patent’s Specification uses “computer system” to refer to a wide range of equipment, from a component of a computing device, to a whole computing device, to a collection of computing devices. Reply 9–10 (citing Ex. 1001, 4:5–8, 11:15–18, 16:50–55). In one example, the Specification refers to “one or more other computer systems (e.g., protected network devices 136).” Ex. 1001, 18:52–53. Thus, the Specification lists “protected network devices 136” as only an example of “other computer systems,” demonstrating that “computer systems” refers to things other than protected network devices. Although Patent Owner may be correct that this passage more than a single computing device,” we find that other disclosures in the ’872 patent do. Specifically, the Specification uses the language “distributed computer system” when referring to numerous components, including “protected network devices” and an “IDS/IPS system.” Ex. 1001, 3:26–28; Reply 10. In addition to showing that a “computer system” is not limited to a single computing device, this conveys that a “computer system” according to the ’872 patent can include an IDS/IPS.” slip op. at 14

      “Based on our review of the complete record, we find Petitioner’s arguments and evidence to be more persuasive. Patent Owner does not dispute Petitioner’s argument and evidence that capturing detailed information like Goel’s activity sources, activity targets, and association was recognized as enhancing threat analysis. Pet. 44 (citing Ex. 1003 ¶ 79); see PO Resp. 55–59; Sur-Reply 15–17. Additionally, contrary to Patent Owner’s suggestion, we find that the Petition does not propose incorporating Goel’s kernel hooks into Capalik’s system. See Pet. 41–46. Patent Owner contends that the Petition’s reference to modifying Capalik by “adding lines of code” suggests implementing the code disclosed in Goel include kernel hooks. Id. Notwithstanding Patent Owner’s assertion otherwise, this is an unpersuasive bodily incorporation argument, as the Petition never says an ordinarily skilled artisan would have used the exact lines of code from Goel in Capalik. Rather, the Petition says that an ordinarily skilled artisan would have had sufficient skill to implement straightforward code modifications to identify activity sources, targets, and associations: a [person of ordinary skill in the art] would have understood that modifying Capalik’s system (e.g., Linux-based) to additionally monitor, identify, and store each individual activity of an attack including “activity sources, activity targets, and associations” would have required straightforward modifications to programs/code instructions, which would have been well-within the skillset of a [person of ordinary skill in the art]. Pet. 46. Patent Owner argues that Petitioner does not explain how an ordinarily skilled artisan would have modified Capalik without using kernel hooks. Sur-Reply 17. But Patent Owner does not cite any evidence to counter Dr. Jakobsson’s testimony that an ordinarily skilled artisan would have had the skill to apply Goel’s general teaching of identifying sources, targets, and associations to Capalik’s system. Ex. 1003 ¶ 182. On the whole, the evidence does not support Patent Owner’s position that the combination would have required substantially increased detection risk. Moreover, even if the combination would have somewhat increased detection risk, Petitioner persuades us that an ordinarily skilled artisan still would have had reason to combine the references teachings. Patent Owner’s allegations of increased detection risk do not negate the undisputed evidence that the combination would have provided the advantage of improved threat analysis. Pet. 44 (citing Ex. 1003 ¶¶ 175–182). Ultimately, Patent Owner’s that activity logging be undetectable.” PO Resp. 56 (emphasis added) (citing Ex. 1004 ¶ 6). This exaggerates Capalik’s disclosure. Although the cited paragraph suggests that certain systems unfortunately may be detectable by some users, it does not convey that it is a requirement for the system to be categorically undetectable. See Ex. 1004 ¶ 6.8 In sum, Petitioner persuades us by a preponderance of the evidence that it would have been obvious to modify Capalik “to identify and store unauthorized activities including the activity source, activity target, and association of each activity.” Pet. 41–46; PO Resp. 55–59; Reply 20–22; Sur-Reply 15–17.” slip op. at 47

SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (“The patentee bears the burden of showing that a nexus exists”). A showing of sufficient nexus is required to establish that the evidence relied upon traces its basis to a novel element in the claim, not to something in the prior art. Institut Pasteur & Universite Pierre Et Marie Curie v. Focarino, 738 F.3d 1337, 1347 (Fed. Cir. 2013). Objective evidence that results from something that is not “both claimed and novel in the claim” lacks a nexus to the merits of the invention. In re Kao, 639 F.3d 1057, 1068 (Fed. Cir. 2011) (emphasis omitted). Thus, establishing nexus involves a showing that novel elements in the claim, not prior-art elements, account for the objective evidence of nonobviousness. Id. As discussed above, Petitioner shows that Capalik teaches all limitations of claim 1. Petitioner persuades us that none of claim 1’s elements individually nor any combination thereof is novel over Capalik’s disclosure. Accordingly, claim 1 is not novel over Capalik, which disproves Patent Owner’s assertion of nexus. PO Resp. 73–76. Moreover, even if claim 1 were novel, Patent Owner otherwise fails to show nexus for its commercial success, praise, or copying assertions. Patent Owner’s evidence does not show that Petitioner’s commercial product embodies claim 1. For example, we agree with Petitioner that Patent Owner “failed to analyze any meaningful detail regarding” how the Falcon Platform allegedly meets limitation 1(d). Reply 28–29.

      “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.

      “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

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.

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.

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

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
