    “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

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.

    “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.

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.

In addition, we disagree with Patent Owner that “Petitioner provides no reason why a POSITA would have extended Hasei’s method for producing its OLED to a capacitor.” PO Resp. 36; see PO Sur-reply 17 (asserting “pure conjecture”). To the contrary, as noted above, Petitioner explains, with relevant support from Hasei, that its structured application method reduced electrode-material waste and shortened manufacturing times as compared to photolithography. Pet. 25 (citing Ex. 1007 ¶¶ 5, 7). Given those benefits, Petitioner has articulated sufficient reasoning with rational underpinning to support that its proffered combination would have been obvious.

    “Petitioner contends: A person of ordinary skill in the art (“POSA”) at the time of the alleged invention of the ’223 patent would have had a university degree in chemistry and additional expertise or a second university degree in the field of electrical engineering, particularly optoelectronics, or alternatively a university degree in electrical engineering and additional expertise or a second university degree in the field of chemistry. The person of ordinary skill in the art has spent several years studying the structure and function of organic optoelectronic components, in particular OLEDs, and has detailed knowledge of the chemical structure of light-emitting organic layers and the transport of charge carriers to these layers. In this respect, the person of ordinary skill in the art works at the interface between electrical engineering/physics (charge carrier transport and light emission processes in optoelectronic components) and chemistry, in particular organic chemistry (materials and layer stack combinations suitable). Pet. 14 (citing Ex. 1003 ¶¶ 46–47). Patent Owner does not dispute Petitioner’s contention. See generally Resp. Neither party indicates that the result would change depending on the definition selected.

Under that standard, claim terms generally are given their plain and ordinary meaning as would have been understood by the ordinarily skilled artisan at the time of the invention and within the context of the entire patent disclosure. See Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). We construe claim terms only as relevant to the parties’ contentions and only to the extent necessary to resolve the issues in dispute. See Vivid Techs., Inc. v. Am.

    “Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22. Petitioner also argues that an ordinarily skilled artisan would have recognized “that vaporizing materials together would best achieve Ma’s objective of assessing the current density using different Liq doping percentages.” Reply 22 (citing Ex. 1007, 811; Ex. 1020 ¶ 51). Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id. For the above reasons, we determine that Petitioner demonstrates by a preponderance of the evidence that Ma discloses joint vaporization as required by the challenged claims.” slip op. at 15

    “Patent Owner asserts that in Petitioner’s analysis of claim 16, “Petitioner reads out any distinctions between ‘at least a subset’ and ‘a subset.’” PO Resp. 45. Petitioner responds that “[t]he Board should reject Patent Owner’s argument that ‘the subset’ must be a ‘proper subset,’ i.e., a set that is less than the full set of outgoing data.” Pet. Reply 5. Petitioner cites dictionary definitions and other additional authorities to support this conclusion. Pet. Reply 5–6 (citing, e.g., Exs. 1022, 1023, 1024). For example, A Dictionary of Computing defines “subset” as “[a] set T whose members are all members of S,” and contrasts this with a “proper subset.” Ex. 1023, 3. Petitioner further points out that the antecedent basis of “at least a subset” for “the subset” in claim 16 supports its construction. Pet. Reply 6. In our Final Written Decision, after considering Petitioner’s evidence and the language of the claim, we found that the references to “subset” in claim 16 should be construed broadly enough to read on providing any portion of the outgoing data, up to and including all the data, and not a proper subset. FWD 24–25.

We agree with Petitioner that Patent Owner’s argument is not convincing.

    “Rather, as explained above, Petitioner relies on the top portion of Torii’s electrode 13 as the claimed source electrode, and the bottom portions as the claimed conductive portions. That is, even if Patent Owner is correct that the claimed source electrode and conductive portions must be distinct structures, that does not undermine Torii’s disclosure because Petitioner relies on distinct portions of Torii’s larger, single-hashed element labeled electrode 13. Because Petitioner does not rely on the same structure, i.e., the entire electrode 13 of Torii, for each of two distinct claim elements, our conclusion does not conflict with the Federal Circuit’s holding in Becton. See Becton, 616 F.3d at 1254 (holding that a single hinge structure could not be both the claimed spring means and the claimed separate hinged arm); id. at 1255 (noting that “[i]f the hinged arm and the spring means are one and the same, then the hinged arm must be ‘connected to’ itself,” which is “a physical impossibility”) (emphasis added). Instead, we agree with Petitioner that this case is more analogous to Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1231–32 (Fed. Cir. 2011), where the court held the front half of a cutting box satisfied a “cutting box” limitation, and its rear half satisfied a separate “dust collection structure” limitation. See id.; Pet. Reply 3. Like Powell, which “divided the cutting box” into two portions that each met a single claim limitation, Petitioner argues that one portion of Torii’s electrode 13 (the top portion, colored red by Petitioner) discloses the source electrode, and the remaining portions of Torii’s electrode 13 (the bottom portions, colored pink by Petitioner) discloses the conductive portions. See Powell, 663 F.3d at 1231. In Powell, the claim required “[the] cutting box interior [to be] in fluid communication with [the] dust collection structure,” and the court found that this requirement did not require that the two elements “be wholly separate structures.” Id. at 1229, 1231–32. Similarly, we determine that the requirement that the source electrode and conductive portions are electrically connected does not require that these be wholly separate structures. For these reasons, we agree with Petitioner that together, the top portion of Torii’s electrode 13 discloses the source electrode and the bottom portions of Torii’s electrode 13 disclose the conductive portions recited in claim 4.” slip op. at 14

    “We agree with Petitioner that Hebinuma teaches the oval trenches recited in claim 6. See Ex. 1027, Fig. 9. In addition, we agree that Petitioner’s proposed combination would have been obvious because it amounts to no more than a simple substitution of one known element for another, i.e., Hebinuma’s elliptical trenches for Torii’s rectangular ones. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). Thus, with the analysis outlined above, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that its proffered combination would have been obvious to one skilled in the art. See id. at 418. Patent Owner raises several arguments in contesting Petitioner’s obviousness challenge, none of which we find persuasive. For example, we disagree with Patent Owner that Torii and Hebinuma are not analogous art because a skilled artisan “would not have looked to Hebinuma to improve on Torii.” PO Resp. 72–76. The ’867 patent, Torii, and Hebinuma are all in the same field of “power semiconductor device[s] having a trench gate structure.” Ex. 1001, 1:5–8; Ex. 1027 ¶¶ 1–3; Ex. 1030 ¶¶ 1–4. Thus, Torii and Hebinuma are analogous to the ’867 patent. See In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004). We also disagree with Patent Owner’s argument that one skilled in the art would not have had a reasonable expectation of success because Hebinuma’s oval-shaped trenches were “substantially more challenging” than Torii’s “well-known and well-studied” rectangular-trench solution. PO Resp. 77 (citing Ex. 2013 ¶¶ 128–130). Instead, we agree with Petitioner that one skilled in the art could reasonably expect success because the change “requires only minor changes to the photolithography mask” (Pet. 72; see Ex. 1002 ¶ 364), and because both Torii and Hebinuma expressly teach different trench shapes (see Ex. 1030 ¶ 116 (teaching that “the corner portion of the aperture . . . may be rounded”); Ex. 1027 ¶ 49 (teaching that “the contact trench Tc can be formed under similar conditions . . . with the exception of changing the patterning shape”)).” slip op. at 17
