    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “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. See Okajima v.” slip op. at 12

      “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

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “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

    • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for patent owner

      “arguments and evidence, we determine that Patent Owner fails to sufficiently show a nexus between any of its objective indicia evidence and the claimed invention. See Fox Factory, Inc. v. 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. In particular, Patent Owner has not sufficiently addressed limitation 1(d) with the following argument: “1[D] The Falcon Platform transmitted to other computer systems” slip op. at 37

      “We are not persuaded by Petitioner’s arguments and find that Patent Owner has the better position for several reasons.

Second, Petitioner relies on evidence in the Reply that Petitioner failed to specifically identify in the Petition.

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.

      “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

      “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.

      “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).

      “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. 13 (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. Ex. 1005, 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, 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.” Ex. 1005, 17:60–61. Thus, sliding the camera does not necessarily disclose moving the camera to a second distance from the subject. Zhang also does not expressly disclose capturing a second image at a second distance. Petitioner acknowledges as much stating “[a]lthough Zhang does not expressly say that the second image is captured at a second distance different from the distance of the first image, this would have been obvious to a POSITA.” Pet. 61 (citing Ex. 1003 ¶ 1046). Because Zhang does not expressly disclose capturing a second image at a second distance, Petitioner once again relies on expert testimony to argue that the multiple images disclosed in Zhang would have been taken at different perspectives resulting from rotating or translating the position of the camera and that taking images at different distances would have enhanced Zhang’s homography-transformation procedure. Pet. 61–62 (citing Ex. 1003 ¶ 1046). From here Petitioner repeats many of the same arguments it made regarding the parallax approach from Derakhshani, except that these arguments are on even weaker footing because Zhang does not mention taking images by translating the position of the camera, nor even that the multiple images taken should be from different perspectives. Each of these assertions are made solely on the basis of Petitioner’s expert testimony, and as such are not persuasive. Pet. 61–62 (citing Ex. 1003 ¶¶ 1046). Petitioner’s argument that Zhang teaches capturing a second image at a second distance simply lacks sufficient support from Zhang’s disclosure.” slip op. at 25

As discussed above in our summary of the ’606 Patent and reflected in our discussion of Petitioner’s obviousness challenges (see §§ I.F, II.E.1, II.E.2, II.E.3), the unique characteristics of the claim relate to verification of three dimensionality by comparing two images taken at different distances for perspective distortion. Indeed, those features are what distinguish over the prior art. See id. Furthermore, Patent Owner, supported by testimony from its Chief Technology Officer, Mr. Rose, asserts the unique characteristics claimed are reflected in the “3D liveness checks” its ZoOm software product provides because ZoOm “confirms that a user is 3D by comparing images taken at different distances for expected differences in biometric data, such as the presence of appropriate perspective distortion and differences.” PO Resp. 25 (citing Ex. 2059 ¶ 49).

      “We find that these reasons would not have adequately motivated a person having ordinary skill in the art to combine and modify the references in Petitioner’s asserted manner to reach the claimed features. Petitioner’s motivations—“substitution,” “obvious alternative . . . approaches,” “use of a known technique,” and “complimentary” techniques—are all similarly based on swapping or adding techniques for verifying three dimensionality. See Pet. 12–16; Pet. Reply 6–7. These motivations might have been suitable had Tanii described techniques for verifying three dimensionality, but Petitioner has not shown that Tanii describes any technique to verify three dimensionality. See Pet. 13–17, 25–28. Instead, as discussed above, Tanii describes the existence of the perspective distortion phenomenon and a technique for correcting it. As such, substituting the knowledge that perspective distortion exists and techniques to correct it does not correspond with approaches for verifying three-dimensionality, and so does not adequately motivate Petitioner’s combination. Put another way, because Tanii does not teach an approach for verifying three-dimensionality, Tanii’s techniques cannot be used as a substitute for approaches that do verify three dimensionality simply because Tanii discloses the concept of perspective distortion.” slip op. at 18

      “none of the relied upon references teach capturing two images at two different distances, as required by limitations 1[d3] and 1[d4]. These limitations recite “moving the camera from a first location to a second location, the second location being a second distance from the user” and “capturing at least one second image of the user taken with the camera of the computing device at the second distance from the user, the second distance being different than the first distance.” Derakhshani does not teach capturing a second image at a second 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. 13 (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. Ex. 1005, 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

      “summarized above, we determine that a person of ordinary skill in the art would not have implemented Toge’s physician-side computer as a web server using a “localhost” architecture as proposed by Petitioner because such a configuration cannot communicate with external devices over the public internet, a deficiency that directly contradicts Petitioner’s stated motivations for the combination of permitting broad data access. Petitioner’s expert, Dr. Chatterjee, expressly acknowledged in his Reply Declaration that when a client and server reside on the same machine, the communications between them do not traverse the internet. Ex. 1069 ¶ 8. Specifically, Dr. Chatterjee cited the Microsoft Computer Dictionary’s definition of “localhost” as “[t]he name that is used to represent the same computer on which a TCP/IP message originates,” noting that “[a]n IP packet sent to localhost has the IP address 127.0.0.1 and does not actually go out to the Internet.” Id. (citing Ex. 1070, 316). Accordingly, Petitioner’s proposed configuration of placing both the client and web server on Toge’s physician-side computer would create a closed loop of communication that does not reach the broader network. Id. As noted by Patent Owner, “[i]f ‘the physician-side computer and the web server are on one machine,’ the local web server would not communicate with other devices via the Internet.” Sur-Reply, 3–4 (comparing Ex. 1069 ¶ 19 with id. at ¶ 8). Thus, the consequence of Petitioner’s proposed Toge-Kumar configuration is that other devices in the system, such as the PAP device that generates the treatment data and any remote client devices that might need to access that data, would be unable to send data to or retrieve data from the localhost web server. Patent Owner persuasively argues, supported by evidence of record, that under Petitioner’s proposed configuration, “the PAP device could not send data thereto nor could other clients receive data therefrom, as only the local client browser can exchange data.” Id. (citing Ex. 1069 ¶ 8); see Ex. 2003, 4 (one-tier architecture “is not suitable for a web application” because “it can only access data available in a single computer or server” and therefore “is not suitable for a web application.”); Ex. 2022, 3 (Unlike more advanced multi-tier systems, a one-tier architecture “cannot transmit information from one client machine to another.”); Ex. 2020, 4 (While “the client process and server process can be on the same computer,” this architecture “is rarely used today” precisely because it cannot “take advantage of the distributed computing environment.”).” slip op. at 29
