    “understanding of a person of ordinary skill in the art (“POSITA”). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). “[O]ne or more factors may predominate.” Id. Based on the testimony of Mr. Crevelt, we determine that a person of ordinary skill in the art would have had at least a bachelor’s degree in computer science or computer engineering, with at least three years of experience in game development. Pet. 14 (citing Ex. 1003 ¶¶ 62–65). Additional experience could substitute for less education, and additional education could likewise substitute for less experience. Id. We determine that the level of ordinary skill in the art adopted above is consistent with the level of technical understanding and competence reflected in the ’336 patent Specification and the asserted prior art references, based on our review of the record. Patent Owner states that “[f]or the purposes of this response, Patent Owner does not dispute Petitioners’ proposed level of skill, and under any level of skill a POSITA would not understand the asserted Grounds to raise any unpatentability issue,” and “this POR and supporting declarations apply Petitioner’s proposed level of skill.” PO Resp. 8. Thus, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’336 patent and the asserted prior art, and we apply it in our obviousness analysis below.” slip op. at 11

    “b) Walker Priority Date Under Dynamic Drinkware, the Petitioner is required to show that “the provisional application provides support for the claims of the patent or published application.” In re Riggs, 131 F.4th 1377, 1384 (Fed. Cir. 2025). Thus, Petitioner must show that (1) at least one claim of Walker is supported by its provisional (U.S. Provisional Application No. 60/378,289 (the “’289PROV”) and (2) the specific subject matter relied upon as prior art is supported by the ’289PROV. Id. Petitioner does provide a detailed explanation about how the ’289PROV supports claim 1 of Walker. See Reply 6–12. However, as Patent Owner argues, Petitioner fails to show that the ’298PROV provides support for the specific subject matter relied on in Walker. See Sur-Reply 3–8. Petitioner only explains how the ’298PROV discloses “predetermined criteria” but does not provide any other explanation for how the other subject matter relied on in Walker is supported by the ’298PROV. Thus, we find that Petitioner has failed to show that Walker is entitled a priority date before May 1, 2003. See Riggs, 131 F.3d at 1384 (noting while “a prior art patent or published application cannot be accorded the benefit of its provisional application’s filing date absent a showing that the provisional application provides support for the claims of the patent or published application,” the challenger must also show that “the specific portions of the patent specification identified and relied on” to demonstrate purported invalidity have written description support).” slip op. at 24

    “We find that Petitioner has failed to show by a preponderance of the evidence that Kelly teaches limitation 1[f]. As Patent Owner persuasively argues, “the game play events” of limitation 1[f] refers to “game play events” in limitation 1[d], but Petitioner does not map “the game play events” identified in limitation 1[d] to limitation 1[f]. In its Reply, Petitioner does not dispute Patent Owner’s assertion, but merely reiterates its arguments from the Petition. See Reply 23–24, 26. However, none of these arguments or evidence demonstrates that the “game play events” in limitation 1[f] are same the “game play events” that are allegedly stored in limitation 1[d]. Even if we accept Petitioner’s contention that it was not identifying button presses, but rather includes “game states and game events in the game process,” Petitioner provides no evidence or even arguments that what it has identified here relates to what it has identified for limitation 1[f]. See Pet. 25–26 (citing Ex. 1005, 25:23–24, 32:27–33, 40:33–45, 56:49–51).

    “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. . . .

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.)

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.

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). Patent Owner has shown it proposes a reasonable number of substitute claims by proposing a single substitute claim for each of challenged claims 1–4, 8–11, and 13–20. 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. See generally MTA Opp. We determine that Patent Owner meets this requirement. 4. No Introduction of New Matter An amendment may not introduce new matter. 35 U.S.C. § 316(d)(3);” slip op. at 22

    “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.

    “The plain language of claim element [1.A] recites “wherein the first material layer is disposed over a first portion of the second material layer;” and claim element [1.B] recites “a landing pad disposed over a second portion of the second material layer.” Thus, the plain language of the claim merely recites that the first material layer is disposed over a first potion of the second material layer and the landing pad is disposed over a second portion of the second material layer. The plain language does not define what constitutes the first or second portions of the second material layer or define the first or second portions of the material layer by what is disposed above the layers. We agree with Petitioner that the term “portion” has a straightforward plain and ordinary meaning: a “part” of a larger whole. Pet. 5 (citing Ex. 1077, 406 (defining “portion” as “a part of a whole”)). The ’838 patent itself repeatedly uses the term “portion” this way. Ex. 1001, 5:40–43 (discussing both “an upper portion” and “lower portion” of a “staircase”), 5:66–6:1 (referencing “a portion of a top surface of a layer”); see also 4:39– 40, 7:15–17, 8:20–33, 8:34–65, 11:60–64, 12:38–59.

    “understanding that the claim term “from bottom to top” refers to the vertical arrangement of word lines in the memory portions from bottom to top and not from source end to drain end, as asserted by Petitioner. Inst. Dec. 17. In other words, the claim terms describing the first and second portions having word lines “from top to bottom” refer to the relative vertical location of the word lines within the memory portions and not to location of the word lines relative to the source or drain. Our construction is based on the plain and ordinary meaning of the express language of the independent claims, which states that the second memory portion is formed either above or below the first memory portion. The forming of one memory portion above or below another portion establishes a top and bottom in relation to those portions. For example, claim 5 is directed to a “program method of memory” that requires a second portion formed above the first portion. A second memory portion that is formed above a first memory portion is on top relative to the first portion. Similarly, claims 1 and 1 and 11, which recite a memory having a second portion formed below a first portion, establish that the second portion is on the bottom relative to the first portion. Thus, the claim language itself establishes the vertical locations of the memory portions relative to each other (e.g., a second memory portion that is above the first portion is on top, relative to the first portion). It follows that claim terms referring to the top and bottom of word lines within the memory portions also refer to relative vertical locations of the word lines within the memory portions. Thus, we understand the plain and ordinary meaning of claim” slip op. at 13

We agree with Patent Owner’s argument, supported by persuasive testimony by Dr. Khatri, that a POSITA would have understood that Dong’s voltage charts (e.g., Fig. 5a) simply represent which voltages are applied to which word lines and do not depict the physical orientation of the wordlines.

Kim’s Figures 17A–22B do not further address the underlying staircase structure that was detailed in the descriptions of the Figures 4–15 embodiments. Thus, it would similarly be a “reasonable inference” that aspects of the stack structure would be understood to apply to the same stack in the embodiments of Figures 17A–22B, which rely upon, in unaltered form, the earlier-described elements of the stack. stack on bottom, they “replace” and “exclude” any prior description of a gate-stack-on-top.

However, as admitted by Patent Owner, all of Kim’s Figures show only a gate-stack-on-bottom structure. Tr. 41:6–7 (“For the first embodiment, it is true that figures show the gate stack on bottom.”). The fact that Kim’s Figures 17A–22B, which add etch-stop and barrier layers to the gate stack, are shown only as gate stack on bottom is merely consistent with the uniform use of gate-stack-on-bottom in Kim’s Figures, which show the layer-by-layer construction of its device. Like Figures 4–15, Figures 17A–22B exemplify rather than limit the description of the previously described memory stack, and do not exclude the gate-stack-onbottom description of the memory stack. Kim can be used for all it realistically teaches, including descriptions in its disclosure that are not represented by specific Figures. See In re Chapman, 357 F.2d 418, 424 (C.C.P.A. 1966) (stating that a reference “is not limited to the disclosures in its specific illustrative examples.”). Accordingly, the record supports Petitioner’s assertion that Kim’s teaching of a gate-stack-on-top alternative for the memory stack would be understood by a POSITA as a memory stack option applicable to its other embodiments having that same memory stack.” slip op. at 11
