“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

“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.

“that either the ’303 application or the ’838 provisional contain adequate written description support for the disputed feature of limitation [10.d]. Though the disclosures cited by Patent Owner indicate that a secondary identifier can be used to aid in verification of a UAV, these disclosures also make clear that both first and second identifiers are transmitted by and received from the UAV. See, e.g., Ex. 2002, 4:15–17, 30:24–31:6; Ex. 2003 ¶¶ 14, 66. Patent Owner’s reliance on disclosure characterized as transmitting an identifier from a remote computing system “through the UAV” (Reply 2) is not persuasive. The cited disclosures from the ’303 application and ’838 provisional generally disclose that the identifiers transmitted by a UAV can be “generated remotely,” such as by a “remote computing system.” Ex. 2002, 14:23–15:2; Ex. 2003 ¶ 45. But Patent Owner has not identified disclosure indicating that a remote computing system may transmit an identifier to the identification receiver. In the ’303 application and ’838 provisional, only the UAV (which is part of the discrimination system, and thus not “remote”) actually transmits identifiers to the identification receiver. Patent Owner is correct in its assertion that an “aerial system identifier can be generated on-board the aerial system” or “generated remotely . . . at a remote computing system.” Mot. 7 (citing Ex. 2002, 14:23–15:2; Ex. 2003 ¶ 45). But even if a UAV’s identifier was at some time in the past generated by a remote computing system, the subsequent transmission of that identifier from the UAV to the identification receiver would not satisfy the plain language of limitation [10.d]. The claim language “receive … a second identifier from a computing system that is remote to the discrimination system” requires the receipt of a transmission of the second identifier from a remote computing system. This claim language limits the source of the received transmission (i.e., where the particular transmission is “receive[d] … from”). Thus, the relevant issue is from where was the recited second identifier received. The relevant is not where the second identifier was originally generated.” slip op. at 12

“We determine that the disputed language in limitation [10.d] is not indefinite. There is no recitation in proposed substitute claim 10 that the second identifier is transmitted solely from the identifier transmission system. Thus, the alleged irreconcilable contradiction cited by Petitioner is not recited in the claims. Petitioner’s position appears to rest on the fact that the ’303 application and ’838 provisional do not disclose receiving the second identifier from a remote computing system. See Sur-reply 6 (“To manufacture written description support, [Patent Owner] argues the claim encompasses identifiers routed ‘through the UAV.’”). Though we agree that limitation [10.d] lacks adequate written description support, this defect does not render the claim indefinite because the scope of limitation [10.d] is otherwise reasonably certain based on its plain language.

“In contrast, the ’393 provisional never discloses that the described drone defense system may use the identity of a detected drone to develop a particular countermeasure. The disclosed RTSS certainly uses identity information to determine whether a drone is a threat. And if a threat is identified, the RTSS immediately starts “a series of processes … to determine what rule of engagement will be applied on the intruding drone.” Ex. 1006 ¶ 10. The ’393 provisional discloses that the system may select a particular countermeasure based on (i) the particular zone within a protected area within which a drone is located, (ii) “the behavior of the hostile drone,” or (iii) “other instructions.” Id. ¶¶ 9, 10. But the ’393 provisional never discloses that these “other instructions” may include the identity of the drone. The system disclosed in the ’393 provisional uses the identity of a drone to determine whether to activate the countermeasure system. See id. ¶¶ 16–18. But there is no disclosure in the ’393 provisional that the countermeasure system, once activated, uses the identity of the drone to develop the particular countermeasure to be employed. See generally Ex. 1006. Thus, though the Whitmarsh reference itself contains ample written description support for limitation [19e], the earlier-filed ’393 provisional does not. On this record, and having reviewed the ’393 provisional in its entirety, we determine that the ’393 provisional does not “reasonably convey[] to those skilled in the art that the inventor had possession of” the subject matter of limitation [19e] of Whitmarsh’s claim 19 “as of the filing date” of the ’393 provisional.

“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

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).

As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them.

“We find insufficient support in the specification or prosecution history to narrow the term “haptic effect” to only one that has not been modified or combined with another haptic effect. The ’738 patent still refers to combined or modified haptic effects as a “haptic effect.” Ex. 1001, 11:35–38 (“a haptic effect may further be modified or combined with another haptic effect” and “the haptic effect can include one or more haptic effects”). We also find no support for importing into the construction of “haptic effect” the ’738 patent’s example in which a haptic effect can be “based on the proximity signal and the touch sensor signal.” That is already an explicit claim limitation. Id. at 14:19–20 (“generate a haptic output signal based at least in part on the first [proximity] and second [touch] sensor signals”). Including that limitation as part of the construction of “haptic effect” would render the limitation superfluous. See Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1237 (Fed. Cir. 2016) (“The Board was correct to not include in its construction of ‘menu’ features of menus that are expressly recited in the claims . . . . Construing a claim term to include features of that term already recited in the claims would make those expressly recited features redundant.”). We also disagree with Patent Owner that the ’738 patent’s references to haptic effects modified or combined with other haptic effects are unclaimed embodiments. The ’738 patent discloses that a proximity-based haptic effect may be combined with a touch-based haptic effect, such as when “a particular haptic effect associated with a particular control on a user interface element [is] further . . . modified or combined with another haptic effect based on the proximity sensor signal,” or when “the haptic effect [to be output by the processor] . . . include[s] a haptic effect meant to confirm ‘pushing’ on a virtual button.” Ex. 1001, 11:32–40. These examples are consistent with the claim language and we find no credible evidence in the record that these embodiments are intended to be excluded from the claimed invention. Thus, we agree with Petitioner that it would be incorrect to construe the term “haptic effect” to include the extraneous limitations Patent Owner proposes. We also agree with Petitioner that a person of ordinary skill in the art reading the ’738 patent disclosure would have understood that a combined or modified haptic effect is still a haptic effect.” slip op. at 11

“We find Petitioner’s arguments persuasive and disagree with Patent Owner’s arguments to the contrary. Ku discloses summing two overlapping vibration signals, one “based at least in part on” data from a proximity sensor and another “based at least in part on” data from a touch sensor. Ex. 1008, Fig. 12 (items 705, 710, and 715). The summed signal 715 is the basis for generating what the user would perceive as a single haptic effect. See Ex. 1004 ¶ 210–212. This meets limitation 1F. We agree with Petitioner’s argument as to why there would have been a motivation to modify Pratt to include Ku’s teachings. Petitioner’s argument is not merely that Pratt was ready for improvement; Petitioner persuasively argues that a person of ordinary skill in the art would have had reason to add Ku’s method for confirming that the user has touched the intended icon to Pratt’s system. Both Pratt and Ku already disclose using both proximity and touch data in generating a haptic effect, and based on the evidence of record, we are of the view that combining the two teachings would not have been uniquely challenging or otherwise beyond the level of ordinary skill in the art.

“We begin with “the context in which a term is used in the asserted claim,” which can be “highly instructive.” Phillips, 415 F.3d at 1314. In this case, claim 1 recites that the claimed assay is “capable of unambiguously detecting the presence or absence of each of said at least M analytes, in any combination of presence or absence, in a single sample volume, . . . wherein the analytes are amplified in the single sample 15 In this regard, we note that Petitioner’s claim construction position is not predicated on the collection of droplets being reconstituted into its original, pre-partition form prior to amplification; rather, the droplets remain compartmentalized from each other in the PCR thermal cycling tube. Tr. 65:21–66:9 (Petitioner’s counsel explaining that the droplets do not combine in the PCR thermal cycling tube but, rather, are “suspended in an immiscible fluid and analyzed en masse”). indicates that the first instance of single sample volume, i.e., the single sample volume in which the presence or absence of each M analytes are to be detected, is the antecedent basis for the second instance of “single sample volume,” i.e., the single sample volume in which the analytes are amplified. Thus, as the parties appear to agree, the single sample volume in which amplification takes places must be the same single sample volume in which the presence or absence of analytes are to be detected. We are not persuaded that, when accorded its plain and ordinary meaning, a single sample volume divided into a collection of droplets would be considered the “same” single sample volume prior to its partition.” slip op. at 17

“With respect to the limitation, “wherein the analytes are amplified in the single sample volume,” Petitioner asserts that “Larson discloses PCR assays that amplify target polynucleotide in a single sample volume, specifically a portion of the reaction mixture that is subsequently partitioned into droplets.” Pet. 31 (emphasis added).

Larson ¶¶ 6–7 (explaining that “[d]igital PCR (dPCR) is an alternative quantitation method in which dilute sample are divided into many separate reactions” and that “[t]he template is amplified in the droplet for detection”) (emphasis added). Because the claims require that amplification of the analytes be in the same sample volume in which the at least M analytes, in any combination of presence or absence, is unambiguously detected, and because the pre-partition single sample volume is not the same single sample volume as the collection of droplets after partition under our claim construction set forth above, we find Petitioner has not shown, by a preponderance of evidence, that claims 1–10 and 13–19 are anticipated by Larson.17 Tr. 68:12–69:14 (Petitioner’s counsel” slip op. at 27

Thus, Petitioner’s proposed combinations “substitute one known n-dopant for another to further the same goal of improving ETL conductivity.” Pet. Reply 10. Next, Patent Owner faults Petitioner for failing to show that using Ma’s Liq dopant in Diekmann’s/Suzuki’s ETL would result in lower diffusion or higher efficiencies as compared to Diekmann’s/Suzuki’s preferred n-dopants, which included cesium, barium, or lithium fluoride. PO Resp. 31–35; see PO Sur-reply 4–5. We disagree with Patent Owner’s argument because Petitioner does not need to show that Ma’s Liq n-dopant “was an improvement in a categorical sense” over Diekmann’s/Suzuki’s n-dopants, so long as Ma’s n-dopant was known and one skilled in the art would understand that implementing it had advantages. See Intel Corp. v. Pact XPP Schweiz AG, 61 F.4th 1373, 1381 (Fed. Cir. 2023) (quotation marks omitted); In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (“[O]ur case law does not require that a particular combination must be the preferred, or the most desirable, combination described in the prior art.”). Petitioner does not assert skilled artisans would have used Liq because it was a superior to Diekmann’s/Suzuki’s preferred dopants, but because doping ETLs with Liq had known benefits including lower driving voltage and enhanced power efficiency from enhanced carrier injection increased transport conductivity, as compared to an undoped device. Pet. 37 (citing Ex. 1010, 813). That other potentially suitable or even superior n-dopants were also known does not make Liq nonobvious. Given Liq’s benefits outlined above, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that its proffered combination of Ma’s known dopant in Diekmann’s/Suzuki’s device would have been obvious to one skilled in the art.

They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
