    “Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network. [0322] Having been routed over a communications network to the base unit 33, the incoming stream is read from the communications interface such as a WiFi access point 22, unpacked in an unpacker 25, decoded in a decoder 26 and then inserted into a suitable composition such as an OpenGL based composition in the compositor 29 for display on a central display device. Ex. 1005 ¶¶ 321–322 (emphasis added to portions quoted by Petitioner). Patent Owner notes that “[t]he Petition mistakenly cites to ¶ 322 of Beel but quotes ¶ 321.” PO Resp. 20 n.3. However, it appears that Petitioner has grafted together a portion of paragraph 321 that introduces peripheral device 32 with a portion of paragraph 322, which discusses features of base unit 33. However, this grafting has been done in such a way as to convey (incorrectly) that peripheral device 32, not base unit 33, includes unpacker 25, decoder 26, and compositor 29 that process the first processed video data received by the first peripheral device to generate second video data. Dr. Almeroth’s testimony, which copies Petitioner’s incorrectly altered quotation to paragraph 322 of Beel, is unreliable as to this claim limitation and is entitled to no weight.4 Thus, Petitioner has no expert testimony on which to rely for this claim limitation.” slip op. at 19

    “5 At the oral argument, when challenged on its reliance on paragraph 322, Petitioner argued that paragraph 321 of Beel teaches this limitation. Tr. 22:26–23:24. Petitioner did not make this argument in the Petition and, instead, raised it for the first time during oral argument; thus, it will not be considered. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364, 1369 (Fed.

Even if we were to consider this new argument, it would not be persuasive. As Patent Owner observes (PO Resp. 20), any processing performed by peripheral device 32 in paragraph 321 is on data received from the processing device and destined for the base station via the network, rather than data flowing in the direction of the first processed video data of claim 1.” slip op. at 22

    “that Boerjes alone teaches or suggests limitation 1(h) by a preponderance of the evidence. Although the Petition is persuasive that Boerjes allows a user to “identify areas that need replacing, such as ‘a margin line’ to be removed, ‘areas of poor margin preparation,’ and ‘holes or areas of incomplete scan[s],’” and that the user can identify regions of a prepared tooth surface requiring additional preparations and “supplemental scanning” (Pet. 32 (citing Ex. 1004 ¶¶ 189, 193, 196)), Boerjes is silent with respect to replacing at least a portion of the removed surface portion of the model using the received second scan data of the patient’s teeth, per claim 1. Boerjes certainly contemplates the re-scanning of the dentition, but does not assert partial insertion of new data into an existing 3D model. We acknowledge that Petitioner has argued (Pet. 43–44) that Boerjes’ Figure 4 and paragraph 144 of Boerjes teach partial replacement, but we are persuaded that those disclosures suggest total replacement and not partial replacement. The reference to “supplemented or replaced with new scan data” (Ex. 1004 ¶ 199) does not necessarily teach or suggest partial scanning, as Petitioner has argued. Additionally, Petitioner has argued (Pet. “combining historical three-dimensional data” (quoting Ex. 1004 ¶¶ 139, 144, 163), would have suggested to ordinarily skilled artisans that “Boerjes would be used to replace at least a portion of the model with the new scan data. Id. at 45 (citing Ex. 1003 ¶ 112). These disclosures are, however, applicable to scans that create complete replacement as well as partial replacement. We remain persuaded that Boerjes does not teach partial scans used to obtain partial replacement. Even under the “comprising” language of claim 1, for example, the complete replacement of a 3D model cannot teach or suggest “replacing at least a portion of the removed surface portion” without repudiating the language of the claim by making a portion be the entire model. Even if, as Petitioner asserts, “removing portions of a virtual model has been a well-known and routine technique in 3D modeling,” and the “process of replacing a user-identified portion would have been well within the skills of a POSITA” (Pet. 35), the disclosure of Boerjes does not teach or suggest such processes. Although Boerjes allows for the possibility that portions of a model can be identified as needing replacement or supplementation, it does not disclose the partial replacement required by the instant, independent claims. Boerjes’s actual disclosure details that supplemental scanning is used to compensate for an inadequate scan, but such supplemental scanning is not disclosed to be used to stitch together before-and-after models that have undergone an intervening physical change.” slip op. at 15

    “image capture device” refers to an imaging-based barcode reader and not a laser-based barcode scanner because we are persuaded that claim language and Specification support that interpretation and also because Patent Owner persuasively shows that a person of ordinary skill in the art would have understood the term as such. Claim 1 recites an “image capture device configured to capture an image.” Ex. 1001, 16:24–25. The plain meaning of the claim term requires that the image be captured, not just scanned. The claim further requires “generating an output based on the information embedded in the image,” requiring that information is retrieved from the captured image. Id. at 16:32–33. A device that does not capture an image is not an “image capture device” under the plain language of the claim. A laser-based barcode scanner employs light reflected from a laser beam to “generate an electrical signal that corresponds to the bars and spaces in the barcode being scanned.” See Ex. 2029 ¶¶ 42–43 (explaining in detail how laser-based barcode self-emitting a laser light across a code to be scanned, with a sensor tuned to capture the reflected light from the laser.”).

Ex. 1004 ¶ 115. In this context, Wang discloses By entering the UPC code or barcode using keypad on the PEAD or scanning in the UPC code or barcode using the input device built into the PEAD such as a barcode scanner or OCR reader, the PEAD can generate the receipt with the list of item prices through the wireless network and Internet by querying the item price using the barcode as the index for price lookup table which is Stored in a Server System. Id. (emphasis added). As discussed above (Section III.C.1), we are persuaded by Patent Owner’s arguments that the claimed “image capture device” refers to an imaging-based device and not a laser-based barcode scanner. Petitioner does not contend that Wang’s disclosure of the barcode scanner necessarily refers to an imaging-based device, but argues that Wang’s disclosure is sufficient because “both imaging-based barcode scanners and laser-based barcode scanners constitute image capture devices.” Reply 11.

Drummond Drummond is a patent titled “Automated Banking Machine System and Method,” and “relates to an automated banking machine apparatus and system that are capable of use in a wide area network, and which provides a user with a remote electronic receipt or other record related to a transaction performed at the machine.” Ex. 1008, code (54), ¶ 2.

And, by doing so, the applicant narrowed the scope of what would otherwise be encompassed in the meaning of “pre-printed lottery ticket” and therefore what would otherwise be encompassed in the scope of the Challenged Claims—a lottery ticket which has lottery numbers associated with it at the time of customer purchase.” slip op. at 27

    “We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (quoting 35 U.S.C. § 316(e)); see 37 C.F.R. § 42.1(d) (2024). This burden never shifts to Patent Owner.

Petitioner must explain with particularity how the prior art would have rendered the Challenged Claims unpatentable. 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104(b)(4) (“The petition must specify where each element of the claim is found in the prior art patents or printed publications relied upon.”). IV. PATENTABILITY ANALYSIS A. Legal Standards A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said (2007). The obviousness inquiry requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed.

    “construction of “threat,” which we find in the context of the ’366 patent does not encompass “risk.” See supra § III.D.3.a.1 (discussing “‘Threats’ versus ‘Risks’”). We agree with Patent Owner that Petitioner’s premise that “risk” includes “threats” or knowing risk allows for determination of threats is false, and belied by the parties’ experts who do not disagree on this distinction, namely that “risk” is not a “threat,” but rather represents the likelihood of a threat occurring compounded by the impact of such a threat on a given system (discussed above). See Ex. 2002, 24:3–25:5, 31:5–33:2 (Petitioner’s expert, Mr. Hurlbut, agreeing that “Risk = Likelihood x Impact”); Ex. 2009 ¶ 80; PO Sur-reply 9–10. Thus, we find unavailing Petitioner’s attempt to walk backwards from Keenan’s explicit disclosure of “risk” modeling into an anticipatory (explicit) disclosure of stored “threats” that may give rise to such risk. Viewing Keenan in the light agreed upon by the parties’ experts, where “risk” is a product of the “likelihood” of a threat occurring and the “impact” of such a threat on a given system, persuades us that although Keenan discloses “risk,” “types of risk,” and “risk ranking” (see, e.g., Ex. 1004, 16:21–63), Keenan uses such “risk” as a given value without explicitly disclosing any underlying stored threats or use thereof. See Ex. 2009 ¶ 112 (“Keenan does not disclose a system for measuring risk. The risk for objects is determined before the objects are imported into the [Integrated Object Environment]. Keenan does not make that measurement.”). Indeed, in order to “store” “threats” in “one or more databases” as recited in claim 1, such “threats” must be identified (i.e., known) at some level of specificity to the system. Petitioner does not direct us to any persuasive evidence that Keenan explicitly discloses using “threats” or “storing” an identified “threat,” let alone storing such “threat” in a database along with its association with a particular threat model component, and even more so with a threat model component that itself is correlated with a third-party diagram component as recited in claim 1.” slip op. at 32

A “polled web site” page cannot be ranked in the Burrows system because the Burrows ranking is performed only after a user query is performed. Only at that time can the Burrows system provide a ranked list (of qualified webpages) for presentation to the user. As Burrows discloses, the Automated Web Browser is robotic in nature and not associated with the queries of users. Ex. 2009 ¶ 181. Mr. Occhiogrosso’s testimony on this point is consistent with Burrows’ description, credible, and entitled to substantial weight. We have considered Mr. Lipoff’s testimony that a skilled artisan “would have understood that combining Burrows’s polling mechanism receiving no response into Kovatch would decrease the entries’ ranking or placement in Kovatch’s destination tree in order to further limit the pages that may not be of interest to the user.” Ex. 1002 ¶ 172 (citing Ex. 1006, 1:38–46). That testimony, however, is conclusory and lacks persuasive reasoning. Moreover, the passage in Burrows to which it cites (Ex. 1006, 1:38–46) does not teach or suggest decreasing the ranking of webpages.

Pet. 38 (citing Ex. 1004, 8–64); see id. at 31–44. We agree with Patent Owner that the Petition does not explain how Jiang’s pruning would be implemented in Chen’s multiple clusters of processors to generate an initial score for an audio sample, and to use the initial score “to determine whether to continue processing” as required by limitations 1(d) and 1(e). In contending that Jiang alone teaches limitations 1(d) and 1(e), the Petition quotes from Jiang’s description of its pruning technique: scores assigned to that node with the largest score on any of the other nodes corresponding to the frame being considered. If the score at a particular node is sufficiently low compared to the maximum score for other corresponding nodes in tree 77, it is assumed that the branches leading to the node under consideration (the node with the lower score) will not likely be part of the completed most likely phoneme sequence (i.e., the phonemes in that sequence will not likely be part of the final word recognized by the system). Thus, that branch is dropped (or pruned) from tree 77 and is no longer considered in further processing. Pet. 38–39 (quoting Ex. 1004, 8:52–64) (emphasis in original).

That is, the Petition does not explain how each of the processors in the four clusters of Chen, after generating a score for one of the initial nodes, would compare the score with the maximum score of all corresponding initial nodes in tree 77.

So when each of the processors has performed its task on its set of trees, it can produce a set of numbers, and looking at the numbers across all of the processors, across all of the results, we can choose a pruning threshold just like Jiang chooses a pruning threshold after it performs all these operations in serial as opposed to parallel. inconsistent with Jiang’s teaching that pruning is performed by comparing a score at a particular node to the maximum score for other corresponding nodes in the prefix tree. Ex. 1004, 8:55–64. We rely on Dr. Anderson’s testimony, that a parallel implementation of Jiang’s algorithm “requires extensive communication between computational components” and that “all four memories 104(a)-(d) would contain necessary information” to perform limitations 1(d) and 1(e), in finding that performing Jiang’s algorithm using Chen’s clusters of processors would have required the processors to access data in all of the cluster memories 104a-d in order to determine the scores of the corresponding nodes of the tree.

Reply 20–21. We disagree, and find that Dr. Anderson’s testimony is sufficiently supported by evidence, including Jiang, Chen, and Mr. Schmandt’s Declaration. For example, Dr. Anderson testifies that the Viterbi algorithm compares most likely outcomes from the previous frame. Ex. 2020 ¶ 29 (citing Ex. 1004, 1:19–39, 2:1–26). Dr. Anderson testifies that to perform these comparisons requires extensive communication between computational components that can have a drastic impact on system performance. Id. ¶¶ 29, 43. Dr. Anderson testifies that as a result, performing Viterbi decoding when the information needed may be in a cluster that is not directly accessible, as in Chen, is not likely to be successful in a practical speech recognition system. Id. (citing Ex. 1003 ¶ 95; Ex. 1005, 9:10–39); see id. ¶ 43. Thus, Dr. Anderson further supports his testimony with citations to Jiang, Chen, and Mr. Schmandt’s Declaration. In addition, Mr. Schmandt does not support with objective evidence his testimony that using Chen’s clusters of processors would have increased the computing power for implementing Jiang’s speech recognition techniques to desirably result in improved processing speed and power.
