      “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. 13–17; Pet. Reply 16–17. Those motivations might have been suitable had Tanii described techniques to verify 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 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

      “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.

      “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. As such, the 3D liveness checks provided by Patent Owner’s software are indicative of the unique characteristics of the claimed invention and, as we discuss below, certain objective indicia of nonobviousness have a direct nexus to the 3D liveness checks of its software.” slip op. at 30

With respect to Petitioner’s appeals, the Federal Circuit addressed the “dictionary routine” claims (claims 14–19 and 33–40) and the “normalization” claims (claims 43–46). Appeal Dec. 7–14. For the “dictionary routine” claims, the Federal Circuit vacated and remanded, stating that In sum, as Google contends and we now hold, the “dictionary routine” claims can be practiced by use of an already-created dictionary, and do not also require the automatic creation of a dictionary. The Board needs to consider Google’s evidence and argument by applying this construction of the automatically classifying and storing limitation, and using this understanding to determine whether Conlon may, in fact, render the “dictionary routine” claims obvious (and, relatedly, whether its prior distinctions of Conlon may be immaterial). Appeal Dec. 10–11. For the “normalization” claims, the Federal Circuit also vacated and remanded, stating that our “decision to exclude Google’s rebuttal argument and supplemental declaration is based on a clear factual error,” so on remand we “must include evaluation of the evidence and argument Google provided in reply.” Id. at 13–14.

      “The Federal Circuit concluded that Petitioner’s construction of “automatically classifying and storing” (as recited in limitation [14.3]), is correct. Appeal Dec. 8. That is, “the ‘dictionary routine’ claims can be practiced by [the] use of an already-created dictionary, and do not also require the automatic creation of a dictionary.” Id. at 10; see also Reply 7 (the limitation is “directed to the use of a dictionary function to automatically look up words and their syntax”); Appeal Dec. 8 (“nothing about the term . . . would inform a person of ordinary skill in the art that automatic ‘creation’ of a database, in addition to the ‘use’ of an already-created database, is a requirement of the dictionary routine claims”); id. (“the plain and ordinary meaning of the claim language is broad enough to include ‘use’”); id. (agreeing with Petitioner that “the specification describes the ‘dictionary routine’ as the act of looking up words already in the database”); id. at 9 (stating that “[i]t is notable, as well, that the specification nowhere describes automatically creating a dictionary; all instances of creating dictionary entries rely, at least in part, on manual data entry by users”). As directed by the Federal Circuit, we will apply this construction in our analysis.8 Id. 8 Patent Owner argues that the Federal Circuit “cherry-picks” and misinterprets the patents’ specifications, and “ignores the clearly contrary specification language.” PO Remand Br. 4–5, 10; id. at 8 (arguing that that the specification clearly set forth the definition of the claim term, and “the Board must accept term definitions . . . above all external definitions”).

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successUnpatentableMotivation foundUnpatentable

      “We agree with Petitioner that claim 43 is obvious over the combination of Conlon, Miller, and Fong. The Federal Circuit stated, “[i]n this context, ‘normalization’ generally refers to de-duplicating and simplifying database entries (for instance, combining entries for ‘car’ and ‘automobile’).” Appeal Dec. 4 (cited at Pet. Response Br. 5). This is consistent with the disclosure in the ’433 patent. E.g., Ex. 1001, 16:55– 17:24 (discussing, for example, “recogniz[ing] that the differently named data elements in different structures are actually the same data element . . . is referred to as normalizing the names of the same data elements,” “recogniz[ing] that the same named data elements in different structures are actually different data elements . . . is referred to as normalizing the names of the different data elements,” and “normalizing multiple single data elements”). This is also consistent with how Fong describes “normalization.” Ex. 1029, 76 (The “Function” of “Normaliz[ing] the collection of entities” is to “[r]emove redundancies and detect errors”); see also Ex. 1057 ¶ 226. Patent Owner’s arguments that Fong’s normalization is “different” from the normalization described in the ’433 patent does not persuasively rebut Petitioner’s arguments. As Petitioner points out, Patent Owner does not provide a construction for “normalization,” despite claiming that the term is “defined” in the ’433 patent. Pet. Remand Resp. Br. 6; PO Remand Br. 13. Moreover, although Patent Owner purports to identify differences between the ’433 patent and Fong, the “normalization” applied is expressly recited in limitations [43.1.1], [43.1.2], and [43.2], and the subsequent actions taken on those normalized databases (i.e., comparing and recording) are recited in limitations [43.3]–[43.5]. That is, the “normalization” required by the claim is reflected in the claim language itself, and is broader than argued by Patent Owner. See In re Baxter Travenol Labs., 952 F.2d 388, 391 (Fed. Cir. 1991) (“It is not the function of this court to examine the claims in greater detail than argued by an appellant, looking for nonobvious distinctions over the prior art”). Patent Owner does not explain how these purported “differences” (e.g., that Fong may require the use of “database keys,” “identifiers,” “entities,” or determining ‘non-key attributes’ from key attributes) impacts the claim language, or Petitioner’s showing. See EWP Corp. v. Reliance Universal Inc., 755 F.2d 898, 907 (Fed. Cir. 1985) (A prior art reference “must be considered for everything it teaches by way of technology and is not limited to the particular invention it is describing and attempting to protect”). For the same reasons, as well as those set forth by Petitioner, we are also not persuaded by Patent Owner’s arguments that each DBMS requires a normalization process that is customized for it. Pet. Remand Resp. Br. 6–7. These arguments by Patent Owner also are not commensurate with the scope of the claim language, which does not recite a DBMS, and generally recites “normalizing” or “normalized” without regard to the DBMS. Id. Dr. Jansen provides an example of a database in unnormalized form that is converted into a normalized form, based on Fong’s four conditions, as applied to the claim language. See Reply 31–35; Ex. 1057 ¶¶ 226–261. Therefore, we are not persuaded by Patent Owner’s arguments that Petitioner has not explained how the example maps onto the limitations. PO Remand Resp. Br. 6–12. Patent Owner’s complaint that Dr. Jansen created the graphic in the example does not undermine Petitioner’s showing. E.g., Trial Practice Guide,14 I.G., (“Experts may testify about the teachings of the prior art and how they relate to the patentability of the challenged claims.”). We find Dr. Jansen’s testimony credible and persuasive in explaining why the combination of Conlon and Fong teaches the claim limitations. After considering the properly presented evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that the combination of Conlon, Miller, and Fong teaches the limitations in claim 43, that one of ordinary skill in the art would have been motivated to combine the teachings of Conlon, Miller, and Fong, and that claim 44 would have been obvious over Conlon, Miller, and Fong. 2. Analysis of Dependent Claims 44–46 Claims 44–46 depend, directly or indirectly, from claim 41. We, likewise, determine whether the combination renders obvious claims 44–46, taking into account the arguments made in Petitioner’s Reply Briefs and Dr. Jansen’s Supplemental Rebuttal Declarations. Petitioner contends that dependent claims 44–46, would have been obvious over Conlon, Miller, and Fong, and provides explanation as to how the prior art teaches each claim limitation. Pet. 84–86; Reply 35–39; Pet. Remand Br. 13–14.

      “Patent Owner’s arguments do not undermine Petitioner’s showing. Patent Owner did not specifically challenge Petitioner’s contentions as to the sufficiency of Conlon’s disclosure for claim 1410 in the Patent Owner Response. In the Sur-replies, Patent Owner argues that the claim requires that at least some relationships are created “automatically,” and “these automatic embodiments . . . are represented in this group of claims.” Sur-reply 9. Along these lines, in the additional briefing Patent Owner argues that Conlon does not teach “automatic,” but merely teaches “semi-automatic.” PO Remand Br. 9–10. The crux of Patent Owner’s argument, however, is that the Federal Circuit did not properly construe the limitation, and ignored certain disclosures in the ’433 (and ’680) patent. Id. at 10–11; see Pet. Remand Resp. Br. 1–4; PO Remand Resp. Br. 4–5. The Federal Circuit held that “the dictionary routine claims can be satisfied by mere use of a lexical database, and do not also require the automatic creation of additional definitions.” Appeal Dec. 10. Moreover, the statements from Conlon that Patent Owner relies upon relate to creating a database, not using the database. See id. As discussed above, on remand we are directed to apply the Federal Circuit’s construction. Patent Owner does not explain 10 As discussed in the original Final Written Decisions, Patent Owner raised several arguments that generally applied to all the claims, challenging, for example, the level of ordinary skill in the art, whether Conlon, Miller, and Beckwith were analogous art, and several general arguments relating to Conlon and the motivation to combine Conlon with a DBMS. See Final Dec. 14–23, 25–27. We were not persuaded by Patent Owner’s arguments; the Federal Circuit affirmed, determining that our findings were supported by substantial evidence. Appeal Dec. 14–16. why Petitioner’s contentions are not persuasive in light of the Federal Circuit’s construction of this limitation. In addition, Patent Owner argues in the Sur-replies that “[c]laims 14– 19 are not disclosed by the proffered prior art” and cites to paragraphs 78–83 of the Ranka Rebuttal Declarations. Sur-reply 10. As discussed in the original Final Written Decisions, Patent Owner’s reliance on six paragraphs of Dr. Ranka’s Rebuttal Declarations is an improper incorporation by reference, as Patent Owner did not discuss that testimony or further elaborate on these arguments in the Sur-replies. 37 C.F.R. § 42.6(a)(3); Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 9–10 (PTAB Aug. 29, 2014) (informative); see, e.g., Final Dec. 37–39, 45, 48–50, 52. Therefore, we will not consider arguments that are not made in the Sur-replies, but are instead improperly incorporated by reference to the cited paragraphs in Dr. Ranka’s Rebuttal Declarations. Accordingly, after considering the evidence and arguments of the complete record, we determine that Petitioner has shown, by a preponderance of the evidence, that Conlon teaches limitation [14.3], and that claim 14 would have been obvious over Conlon.” slip op. at 21
