Ex. 1010, 17:31–33. Baby Jogger improperly reads “seats” out of the claim and substitutes the seat’s “mounting points” on the frame. A proper reading of the claim language focuses on what happens when both seats are connected to the frame, not where they are so connected. In other words, “when connected to the frame” simply emphasizes that both seats must be connected to the frame to form the inline descending configuration, as opposed to the single stroller embodiment of Figure 1, where there cannot be an inline descending configuration because only one seat is connected to the frame and the other seat is removed, i.e., not connected to the frame.

    “Instead, Evenflo’s argument rests on isolating the statement—“A similar sub-frame arrangement is disclosed in [Offord ’797]”—from the remainder of the passage in which that statement appears in order to arrive at a reason to incorporate the reversibility teaching of Offord ’797. However, when that statement is read in the context of the full passage in which it appears, nowhere does that passage suggest reversibility as the reason for referencing Offord ’797. More accurately, it suggests a different reason that relates to a curved lug 108 by which sub-frame 100 rests on the stroller’s main frame 4 to carry the weight of the stroller’s two occupants— When the interface components 100 are attached to the frame assembly 4 they form a sub-frame of the frame assembly 4, and when the child-carrying units are mounted thereon, one behind the other, they are in a compact echelon formation, one of the connector sockets 106 of each component 100 being at a higher level in relation to the ground than the other connector sockets 106. The higher connector socket 106 and further connecting leg 102 are both connected to the respective opposite ends of an upper mounting piece 107. In addition, on the inner side of the lower connector sockets 106 there is a downwardly curved lug 108 which serves to rest upon a part of the basket frame 44, such that the weight of two infants is fully supported by the frame assembly 4. A similar sub-frame arrangement is disclosed in [Offord ’797]. Ex. 1051, 9:23–36 (emphasis added). That passage shows that, rather than reversibility of the sub-frame, the reference to Offord ’797 is more aptly directing the reader to the arrangement and details of a similarly curved lug structure in the stroller sub-frame of Offord ’797. Indeed, Figures 5 and 6 of Offord ’797, reproduced below, disclose just such a curved lug in the context of “corner pieces 20” having “channel 21.” Ex. 1054, 4:10–23.” slip op. at 53

    “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 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

  • 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.

As such, substituting the knowledge that perspective distortion exists and techniques to correct it does not correspond 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 16

    “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

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.

    “Patent Owner has demonstrated a nexus by showing that certain objective indicia, discussed below, are the direct result of the unique characteristics of the claimed invention. 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). Patent Owner’s assertion is further supported by a “FaceTec Software Explanation” stating that its software uses “near & far image data . . . to determine if the expected differences in perspective distortion are present in the image data” and, from that, “decides if there is sufficient evidence in the image data to conclude with a high degree [of] confidence that the image data contains first-generation biometric data captured in real-time from a live, physically present user.” Ex. 2067; see PO Resp. 25–26.

    “layer pierced through with holes or apertures,” we are persuaded that Petitioner meets its burden as to this limitation. Petitioner argues that under our construction, Bergstrom’s express disclosure of forming element 60, and Bergstrom’s explanation of the properties of forming element 60, meets the claimed “perforated polymeric layer” limitation. Pet. 38–41 (citing Ex. 1002 ¶¶ 114–117). Even under Patent Owner’s proposed construction, Petitioner argues, forming element 60 would also allow free flow of liquid bodily waste. Pet. Reply 3– 4 (citing Ex. 1021 ¶¶ 20–23). Importantly, Bergstrom expressly discloses: “suitable materials for the forming element 60 are plastic films, perforated plastic films and reinforced tissue or reinforced nonwoven materials.” Ex. 1004, 10:1–4. This express disclosure is clear. Even though the forming element 60 in Bergstrom might be “typically” liquid-impermeable (Ex. 1004, 9:24–30), that does not preclude a layer that is perforated, particularly where Bergstrom expressly discloses a perforated plastic film as one of the possibilities for forming element 60. Ex. 1004, 10:1–4. Additionally, although Patent Owner focuses on Bergstrom’s disclosure that forming element 60 is “typically liquid-impermeable” (PO Resp. 58–60; Ex. 1004, 9:24–30), we do not view Bergstrom’s use of the word “typically” as mandating that the forming element always be liquid impermeable. We agree that the word “typically” does not mean “always” and that such a reading would render “typically” superfluous. Pet. Reply. 5. We do not find any ambiguity in Bergstrom’s disclosure regarding possible use of perforated plastic films for its forming element 60; whether or not the forming element 60 provides other functions (like stiffness) does not dictate whether it may also be perforated, or be part of a fluid flow control structure. On this point, we credit Petitioner’s arguments and explanation, as supported by Dr. Pourdeyhimi’s testimony. Pet.

    “from the start” (PO Resp. 29), and that “using all or part of [Glaug’s] fluid-acquisition system in place of [Nakazawa’s] diffusion sheet would be antithetical to the teachings of both references” (id. at 35), we agree that the proposed combination of Nakazawa’s structure with the layers of Glaug is sufficiently motivated and reasonably expected to result in a successful article, for the reasons articulated by Petitioner. See, e.g., Pet. 59–65; Ex. 1002 ¶¶ 176–192. Namely, although fluid may flow in both Z directions in Nakazawa (PO Resp. 30), that does not foreclose the combination with Glaug in the manner proposed by Petitioner. See generally Ex. 1002 ¶¶ 176–192; see id. ¶ 184 (detailing the mechanics of the proposed combinations), ¶¶ 188–191 (discussing motivation to combine), ¶ 192 (discussing reasonable expectation of success). The combination can be achieved “either by adding the lower acquisition layer 64 [of Glaug] to diffusion sheet 63 [of Nakazawa], or by replacing diffusion sheet 63 [of Nakazawa] with the two-layer fluid acquisition system 34 [of Glaug],” and as persuasively explained by Dr. Pourdeyhimi, the arrangement constitutes a “fluid flow control structure.” See Ex. 1021 ¶¶ 45–47. Additionally, the diffusion sheet in Nakazawa can be made from the same material as used in Glaug, namely, AquiDry™. Id. ¶¶ 53–55; see also Tr. 17:25–18:3 (“although Glaug does not specify the name AquiDry in its disclosure, Patent Owner’s expert testified that it’s his understanding that Glaug is discussing the AquiDry material, the same material that is in Nakazawa . . . . they disclose using the same material, and Nakazawa says this material work[s]”). When asked if Patent Owner’s expert had any concerns that AquiDry was not the same as between Nakazawa and Glaug, Patent Owner’s counsel replied “They are the same, Your Honor. And we embrace that.” Tr. 46:8–12; see also id. at 58:19 (Petitioner’s counsel commenting about Patent Owner’s counsel: “they agree, AquiDry is used in both Nakazawa and Glaug”). Thus, Patent Owner’s argument that Nakazawa’s diffusion sheet and Glaug’s fluid acquisition layer have different purposes because Nakazawa’s diffusion sheet allegedly must promote fluid flow in the Z-directions, both toward and away from the body (PO Resp. 29–37; Ex. 2004 ¶¶ 26–28, 30– 35)) is not clearly supported by Nakazawa, and is also contravened by the shared disclosure of Nakazawa and Glaug as to the composition of the disputed layer. We have reviewed the complete record, including Patent Owner’s and Mr. Sheldon’s assertions that Nakazawa requires promoting fluid flow in both Z-directions (see id.), but find that Petitioner carries its burden to demonstrate that one of ordinary skill in the art would have been motivated to combine Nakazawa and Glaug with a reasonable expectation of success. On this complete record, Petitioner explains sufficiently why and how a person of ordinary skill would modify Nakazawa’s diffusion sheet, i.e., to use Glaug’s fluid acquisition system, or the lower non-perforated layer of its fluid acquisition system, in Nakazawa, and Petitioner provides well-supported reasons for doing so.” slip op. at 36
