      “F.3d at 1279–80, we begin our analysis with the Specification of the ’711 Patent. The Specification indicates when a UAV (such as the recited “reference aerial vehicle”) navigates autonomously, it flies without manual control, and can, for example, track and fly to a target using information captured onboard the vehicle itself. See Ex. 1001, 3:24–28 (“[I]t may not be desirable to manually control the interceptor aerial vehicle to follow the target UAV. In some embodiments, the interceptor aerial vehicle is able to autonomously track and fly to the target UAV using machine vision based on images captured by a camera of the interceptor aerial vehicle.”). The Specification also indicates that “autonomous” means more than just “automatic flight,” and clarifies that autonomous navigation occurs when a UAV that previously received a target location from an external source subsequently turns and flies itself towards the received location. See, e.g., id. at 4:15–17 (disclosing that the detected location of a target may be provided to an interceptor “to allow it to automatically and autonomously fly toward the direction of the detected location”); 15:64–16:3 (automatic and autonomous navigation occurs when an interceptor’s navigation component and/or flight controller receive the location of a target, and adjust the interceptor “to turn and fly towards the received location . . . based on the received location”); 16:49–60 (“For example, a flight direction and/or speed of an interceptor aerial vehicle are automatically and autonomously adjusted based on a location and size of the target within the captured image. . . . This allows the flight path of the interceptor aerial vehicle to be dynamically adjusted to track and follow a moving target.”).” slip op. at 11

      “have had reason to combine Beard and Laufer in the manner proposed by Petitioner, the combination would not satisfy the Autonomous Navigation limitation required by claim 12 because Laufer’s autopilot commands are generated by and transmitted from a remote command center (i.e., Laufer’s central controller 115). PO Resp. 15–16. In its Reply, Petitioner does not dispute that Laufer’s autopilot commands are generated by Laufer’s central controller 115, which is remote from the aircraft being controlled. See Reply 13–17. Petitioner asserts, however, that the combination still satisfies the Autonomous Navigation limitation because these autopilot commands are generated without human input. See id. Based on the complete trial record, Patent Owner’s arguments are persuasive. See PO Resp. 15–16; PO Sur-reply 42, 1–6; Ex. 2025 ¶¶ 84–87. The flight of Beard’s UAV 100 under the control of Laufer’s autopilot commands does not satisfy the Autonomous Navigation limitation of claim 12, as we have construed that limitation, because Laufer’s autopilot commands are generated at a location that is remote from UAV 100 (Laufer’s central controller 115.) See, e.g., Ex. 1010 ¶ 40 (“Central controller 115 uses autopilot command module 440 to generate autopilot aircraft commands”), ¶¶ 26, 30 (clarifying that central controller 115 and the controlled interceptor aircraft are separate devices that may communicate through a “wireless connection”), Fig. 4 (depicting “aircraft control commands 475” being generated externally from the depicted “Interceptor Aircraft”); see also Ex. 2025 ¶¶ 95–95. Petitioner never disputes that, in the proposed combination, Laufer’s central controller 115 would remain external to Beard’s UAV 100. See Reply 13–17. Instead, Petitioner relies on its proposed construction of the Autonomous Navigation limitation, which would have encompassed such an arrangement. See id. Our construction of the Autonomous Navigation limitation, which did not adopt Petitioner’s claim construction position, is dispositive of Petitioner’s argument. We thus determine that Petitioner has not shown by a preponderance of the evidence that claim 12 would have been obvious over Beard and Laufer.” slip op. at 15

For the reasons that follow, we determine that Patent Owner has satisfied this burden. 1. Proposal of a Reasonable Number of Substitute Claims A motion to amend must “propose a reasonable number of substitute claims.” 35 U.S.C. § 316(d)(1)(B); see also 37 C.F.R. § 42.121(a)(3) (“A motion to amend may cancel a challenged claim or propose a reasonable number of substitute claims.”). “There is a rebuttable presumption that a reasonable number of substitute claims per challenged claim is one (1) substitute claim.” Lectrosonics, IPR2018-01129, Paper 15 at 4; see also 37 C.F.R. § 42.121(a)(3).

MTA 1–2, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 2. Amendments Respond to a Ground of Unpatentability “A motion to amend may be denied where … [t]he amendment does not respond to a ground of unpatentability involved in the trial.” 37 C.F.R. § 42.121(a)(2)(i). Patent Owner has responded to the grounds of unpatentability involved in this proceeding by amending the claims in response to the Petition’s asserted prior art. See MTA 2, 25, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 3. No Enlargement of the Scope of the Claims An amendment may not seek to enlarge the scope of the claims of the patent. 35 U.S.C. § 316(d)(3); 37 C.F.R. §§ 42.121(b)(1)–(b)(2). Patent Owner asserts that the amendments in the Motion do not enlarge the scope of the claims of the patent because each proposed substitute claim “retains all of the limitations of the corresponding challenged claim, and each proposed independent substitute claim adds further limitations.” See MTA 2, Claims App. Petitioner does not argue otherwise.

    • 112 supportDecided for patent owner

      “Having considered the evidence and argument cited by both parties, we determine there is sufficient written description support for the disputed portions of limitations [37.e1], [37.e3,] and [37.e4]. The ’452 application discloses selecting between groups of processing schemes (e.g., algorithms) depending on a confidence level, where the groups are, for example: high cost, high robustness algorithms; medium cost, medium robustness algorithms; and low cost, low robustness algorithms. See Ex. 2019 ¶¶ 146–147. These schemes or algorithms may be neural networks. See, e.g., id. ¶ 50 (including neural network as a type of algorithm); see also id. ¶¶ 109–110); see generally MTA Opp 1 (not disputing that schemes may be neural networks). Specifically, the ’452 application describes “algorithms that process video frames of one or more video data streams,” and “produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Id. ¶ 141. The ’452 application also discloses the concept of switching between neural networks based on confidence levels. In particular, the ’452 application discloses that a “process cycles through the processing schemes to produce a detection of an object,” for example, where “if the confidence number is higher than an activation number, an action is performed to stop or change a running group (i) and select or switch to group (ii).” Id. ¶ 146. More particularly, “a processing scheme from the group of (i) High cost (low refresh rate), high robustness algorithm[s] can select a cheaper processing scheme from the group of (ii) Medium cost, medium robustness algorithms.” Id. The ’452 application additionally discloses that schemes or algorithms (e.g., neural networks) are applied to individual video frames, and that the confidence levels that determine which neural network will be applied in the future are also derived from individual video frames. For example, as discussed above, the ’452 application describes that “[t]he processing schemes produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Ex. 2019 ¶ 141 (emphases added). The ’452 application also describes selecting and applying an individual neural network, rather than only selecting and applying a group of processing schemes. For example, as highlighted above, the ’452 application describes that “a processing scheme from the” “High” group “can select a cheaper processing scheme from the” “Medium” group. Id. ¶ 146 (emphases added). In our view, these disclosures, read together, would reasonably convey to one skilled in the art that the inventor had possession of the disputed subject matter described above.

      “First, Patent Owner has not shown possession of the disputed feature of a “radio communication module [that] is configured to utilize a secure identifier, the secure identifier comprising a specified excitation.” In the ’406 application, the term “excitation” is used exclusively to refer to a light beam signal. See Ex. 2015, 7:8–13, 9:8–10, 23:9.2 The ’406 application discloses that an identification box on an aircraft may include both an RF module and a separate light sensor. See Ex. 2015, 7:3–11. But nowhere does the ’406 application describe receiving a light beam (e.g., an excitation) with the RF module of the identification box (as opposed to the light sensor), so as to provide support for proposed substitute claim 22’s recitation of a “radio communication module” configured to utilize “a secure identifier . . . comprising a specified excitation.” We disagree with Patent Owner that it suffices that one of ordinary skill in the art “would recognize that these disclosures are equally applicable to the RF-only embodiments” (Reply 5). “It is not sufficient for purposes of the written description requirement . . . that the disclosure, when combined with the knowledge in the art, would lead one to speculate as to modifications that the inventor might have envisioned, but failed to disclose.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). On this record, and having reviewed the ’959 Patent, the ’153 provisional, and the ’406 application, we find no evidence in those documents that the named inventor was in possession of the concept of a radio communications module “configured to utilize a secure identifier” where “the secure identifier compris[es] a specified excitation.” Second, setting aside the “radio communication module” in proposed substitute claim 22, Patent Owner also has not shown that the named inventor was in possession of the feature of a “secure identifier comprising a specified excitation.” Patent Owner’s argument that the ’406 application describes a light beam directed to a particular aircraft (see Reply 4–5) is 2 The same is true of the ’153 provisional. See Ex. 2016 ¶¶ 29, 34. unavailing. The fact that the properties of a particular light beam indicate that the light beam is intended for a particular aircraft does not demonstrate that the light beam is a “secure identifier,” as we have construed that term. Patent Owner has not identified any disclosure in the ’406 application of a “secure identifier” comprising a light beam, let alone that such light beam can be utilized by a “radio communication module.” The only references to “secure” identifiers in the ’406 application describe radio frequency signals. See Ex. 2015, 2:4–6, 15:21–17:12.3 Having reviewed the ’959 Patent, the ’153 provisional, and the ’406 application, we find no evidence in those documents that the named inventor was in possession of the concept of a “secure identifier comprising a specified excitation.”” slip op. at 15

    • ScopeDecided for patent owner

      “not impermissibly broaden the scope of the claims of the ’959 Patent. As Patent Owner suggests, there were no limitations in original claim 21 on the type of radio signal the radio communication module could receive, and so it follows that proposed substitute claim 22 does not now encompass receiving a broader set of radio signals. We see no basis for Petitioner’s argument that the past tense verb “received” limited original claim 21 to “signals of a compatible ‘type’ and ‘range.’” Opp. 7. Moreover, the claim language (with the proposed deletion shown double brackets) provides that “the radio communication module is configured to receive a [[received]] radio signal.” Any radio signal that the radio communications module receives would necessarily be a “received” radio signal. Thus, deleting the redundant word “received” does not enlarge the scope of this claim limitation. We also are not persuaded by Petitioner’s suggestion that removing the term “received” broadens original claim 21 by deleting a requirement that the radio signal have already been previously received by the claimed device. See Sur-reply 9. Original claim 21 simply recited, using redundant language, that “the radio communication module is configured to receive a received radio signal.” Ex. 1001, 18:5–7. The most natural reading of this language is that the phrase “received radio signal” is just a description of a radio signal that is received by the recited radio communications module. Petitioner has cited no persuasive evidence that one of ordinary skill in the art would have counterintuitively interpreted this language to impose an additional requirement that the “received radio signal” must have been received twice—a first time by some other component of the device, and a second time by the recited radio communication module. Accordingly, we determine that the proposed amendment does not improperly broaden claim scope.” slip op. at 10

    • Disclosure Requirements (§112) › Definiteness (Nautilus)IndefiniteNot shown unpatentable

      “572 U.S. 898 (2014). See Memorandum: Approach to Indefiniteness Under 35 U.S.C. § 112 in AIA Post-Grant Proceedings (Jan. 6, 2021).4 Under Nautilus, a claim is indefinite if fails to “inform those skilled in the art about the scope of the invention with reasonable certainty.” 572 U.S. at 910. We agree with Patent Owner that neither of the identified terms are indefinite. Regarding the term “low-altitude aircraft,” we determine the Specification provides a sufficient basis for understanding the scope and meaning of this term with reasonable certainty. The U.S. Court of Appeals for Federal Circuit has explained that, when a term of degree is recited in a claim, it is necessary “to determine whether the patent’s specification provides some standard for measuring that degree.” See Seattle Box Co. v. Indus. Crating & Packing, Inc., 731 F.2d 818, 826 (Fed. Cir. 1984); see also Datamize, LLC v. Plumtree Software, Inc., 417 F.3d 1342, 1350 (Fed. Cir. 2005) (“Some objective standard must be provided in order to allow the public to determine the scope of the claimed invention.”). Here, the Specification describes the related art as including “small UASs (e.g., aircrafts up to 25 pounds flying up to 500 ft of the low altitude airspace).” Ex. 1001, 1:50–52. One of ordinary skill in the art would understand from the Specification that the cited disclosure provides an objective standard for determining the scope of a low-altitude aircraft as one that is designed to fly up to a maximum altitude of about 500 feet.” slip op. at 20

      “We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12

      “The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration.

      “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

      “Finally, Petitioner explains in detail why and how a person of ordinary skill in the art would have had reason to combine the teachings of Carmel and Mattavelli, with a reasonable expectation of success. See Pet. 50–55. Specifically, an ordinarily skilled artisan would have modified Carmel’s system to use “Mattavelli’s CGD techniques to optimize the decoding of in more efficient network bandwidth usage and improved playback of multimedia data streams. Id. at 50, 52–53, 55. Petitioner contends that Carmel and Mattavelli are both directed to processing multimedia data playback “for the appreciation of a user,” while providing the highest perceived audio and video output quality possible in view of system constraints to ensure playback continuity. Id. at 50–51 (citing Ex. 1003, 7:35–49, 10:48–54, 11:9–18, Figs. 3D, 6B; Ex. 1004, 2309–10). Petitioner argues that Carmel and Mattavelli both pertain to compression of multimedia data using well-known coding and compression standards for video streaming. Id. at 51 (citing Ex. 1003, 7:25–26, 11:24–52; Ex. 1004, 2309–11). Petitioner further asserts that a person of ordinary skill in the art would have appreciated that Carmel and Mattavelli “complement[]” each other because Carmel addresses constraints on available network bandwidth and Mattavelli addresses limits on available processing resources at the client/multimedia player. Pet. 52 (citing Ex. 1003, code (57), 7:36–41; Ex. 1004, 2309–2312). According to Petitioner, an ordinarily skilled artisan would have been motivated to combine the complementary teachings in Carmel and Mattavelli to create a more robust streaming system that addresses both bandwidth constraints and client processing limits to provide the best possible playback experience. Id. (citing Ex. 1002 ¶¶ 212–215). Petitioner also contends that Mattavelli teaches that merely optimizing transmission bandwidth is not sufficient and is potentially harmful, which provides an express motivation to combine Carmel’s and Mattavelli’s complementary teachings to ensure that different, related links in the streaming playback chain are optimized together. Id. at 53 (citing Ex. 1002 express disclosure that would have motivated a person of ordinary skill in the art to incorporate Mattavelli’s complementary teachings regarding decoding because Carmel states that multimedia playback is achieved “preferably with only a minimal necessary transmission and decoding delay.” Id. at 53–54 (quoting Ex. 1003, 10:50–54; citing Ex. 1002 ¶ 218). Patent Owner in its Response does not dispute that Carmel and Mattavelli teach the preamble and limitations 1[a.i]–1[c.i], or that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner.6 Nonetheless, the burden remains on Petitioner to demonstrate unpatentability.

      “In response, we conclude that the most natural reading of limitation [l] results from examination of the entire limitation: “locating encryption information that identifies encrypted portions of frames of video within the requested portions of the selected stream of protected video.” Ex. 1001, 27:54–57. The “within” most naturally connotes where the encrypted portions of frames of video occur, as opposed to determining where the encryption information may be located. Patent Owner’s interpretation is not wrong, i.e., the limitation could be read as Patent Owner suggests, leading to a narrower construction, but we are not persuaded that the construction of limitation [l] must be so limited, on the basis of the words themselves. We continue to reject Patent Owner’s interpretation that limitation [l] requires locating encryption information within the requested portions of the selected stream of protected video. See Inst. Dec. 27–30; 1st Final Dec. 8. Although it is apparent that encryption information can be found within the requested portions, we are not persuaded that the claim language or ’588 Patent implicitly or explicitly requires such a relationship. Likewise, although embodiments disclosed in the Specification of the ’588 Patent are consistent with Patent Owner’s more restrictive construction, the Specification also is consistent with the more grammatically correct construction as well. Thus, we construe limitation [l] as requiring that the encrypted portions of frames of video be within the requested portions of the selected stream of protected video, but we do not construe limitation [l] as requiring that the encryption information be within the requested portions of the selected stream of protected video.” slip op. at 15

      “1. “closed loop” The term “closed loop” is recited in each independent claim. Petitioner asserts that in the Delaware action , the district court construed “closed loop” as “gas pathway within a display housing containing gas that is essentially isolated from external air.” Pet. 11 (citing Ex. 1026, 1). Petitioner asserts that the district court’s construction is the proper construction, in light of the specification and the prosecution history of the ’740 patent. Id. at 11–12. Petitioner explains: The ’740 patent refers to the gas/air, circulating through a closed loop as the circulating gas/air and also as the “isolated gas.” (Ex. 1001, 9:64–10:3, 10:7–9, 10:56–58, 11:30–12:6 (claims reciting circulating gas/air), 3:30–[39], 3:50–52 (specification referring to gas in the closed loop as “circulating gas” and “isolated gas”), FIG. 1.) Moreover, as noted above, the Applicant distinguished the claims from the Thielemans prior art based on the argument that the closed loop must be separate from and in addition to the open loop. (Ex.

The Court’s “closed loop” construction should apply here, though Applicant notes that this claim construction does not affect the applicability of the prior art in this Petition because the art teaches the separate loops. Id. at 12. Petitioner’s characterization of the prosecution history with respect to the Thielemans reference is inaccurate. Our review of the cited portions of the prosecution history reveals that the Applicants did not argue to the Examiner that the closed loop and the open loop must be isolated from each other and cannot mix. Rather, the Applicants argued that Thielemans discloses having an open loop or a closed loop, not both an open loop and a closed loop. Ex. 1031, 44–45, 160. The Applicants also argued that Thielemans’s closed loop is not “about” and is not “encircling” the electronic image assembly. Id. at 160.
