“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

“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.

On the record before us, we do not agree that the ’171 Patent is entitled to a filing date earlier than Jan. 11, 2021. In particular, we do not agree that PCT ’199 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the performing preset padding before the FCS field of the trigger frame according to one embodiment (see Ex. 1012 ¶ 136, Fig. 20); and (4) inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a frame for allocating resource for uplink (UL) multi-user (MU) transmission to one or more terminals that includes the AID field set to a value related to a first padding field, when the padding field is included in the frame. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) an AID field for the MU UL resource allocation frame is set to a value, (2) that the AID field is set to a value related to the padding field, and (3) that the AID field is set to a value related to the padding field, and conditioned on the inclusion of the AID field in the frame. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments.

“of an earlier application, the earlier application must provide written description support for the claimed subject matter. Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997); see also VasCath v. Mahurkar, 935 F.2d 1555, 1563–64 (Fed. Cir. 1991) (“[T]he applicant must [] convey with reasonable clarity to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention . . . now claimed.”), Ariad Pharm. Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). On the record before us, we do not agree that the ’186 Patent is entitled to a filing date earlier than April 8, 2019. In particular, we do not agree that PCT ’199 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support, show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the stations assigned to each channel (see Ex. 1012 ¶¶ 134–135, Fig. 20); (3) performing preset padding before the FCS field of the trigger frame inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20. PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment. On the record before us, we also do not agree that KR ’754 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 17, 2015 filing date of KR ’754. The disclosures of KR ’754 cited by Patent Owner to show written description support show: (1) multiplexed terminals over respective channels, (see Ex. 1008 ¶¶ 65–66, Fig. 10); (2) differing the number of AID values in the batch acknowledgment (BA) information field when the number of terminals assigned to each channel differs, setting the length of each multiplexed group ACK differently, and, if necessary, aligning the lengths of the multiplexed group ACKs based on the channel with the longest assigned BA information by adding zero padding or repeatedly inserting BA information (see Ex. 1008 ¶¶ 66–70, Fig. 11); and (3) applying the use of the AID field padding and the use of BA padding in a downlink OFDMA trigger process during multi-user downlink transmission to align the length of the trigger when the AP notifies the terminals assigned to each channel by inserting zero padding or repeating AIDs (see Ex. 1008 ¶¶ 71–72, Figs. 11–12). KR ’754 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we do not discern disclosure in KR ’754 that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. We find misplaced Patent Owner’s argument that “KR ’754’s discussion about Figure 10 and Figure 11 would have been understood [by a POSITA] as disclosing a padding method used to improve predictability and consistency trigger frame” (Prelim. Resp. 12) because: (1) it addresses uplink transmissions and not a trigger frame indicating uplink transmission to one or more terminals; (2) it does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) it is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. Argument of counsel cannot take the place of objective evidence. See Gemtron Corp. v. Saint-Gobain Corp., 572 F.3d 1371, 1380 (Fed. Cir. 2009). We also find misplaced Patent Owner’s argument that “the padding discussed by KR ’754 regarding its Figure 12 embodiment is not limited to downlink transmission and would have been understood by a POSITA as also being used to schedule uplink ones” (Prelim Resp. 14) because: (1) KR ’754 does not provide any suggestion that the same technique can be used for uplink transmission trigger frames; (2) Patent Owner’s argument does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) Patent Owner’s argument is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. See Gemtron, 572 F.3d at 1380. For the foregoing reasons and based on this record, for the purpose of institution, we find that the ’186 Patent is not entitled to an effective filing date earlier than April 8, 2019 and find that Kim is prior art. We note that the limitations at the heart of the written description dispute were added in an amendment filed August 9, 2020. See Ex. 1002, 214–21. In further briefing, the parties should address the respective burdens of production and persuasion for establishing that the ’186 Patent is entitled to an earlier” slip op. at 16

“We do not agree with Patent Owner’s arguments because they are premised on Choi’s teachings as limited to AIDs transmitted via a control frame broadcast as a TIM element. A prior art “reference must be considered for everything it teaches by way of technology and is not limited to the particular invention it is describing and attempting to protect.” EWP Corp. v.

Chu, Choi, and the testimony of Dr. Ding (Ex. 1003), we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to combine Chu’s teachings with Choi’s use of specific AID or ΔAID values as indicators of the end of meaningful data and the beginning of padding that would allow client stations to reliably determine where the useful content of the trigger frame ends and where optional padding begins, with the benefits of improved parsing efficiency, enhanced synchronization, and reduced likelihood of misinterpreting padding as data as padding.

“But the Detecting Limitations of claims 1, 19, and 20, merely require that a target be “detected.” The Detecting Limitations do not require that target detection be performed “aboard the reference UAV,” and claim 19 does not recite or require “machine learning.” Moreover, the Specification makes clear that the claims should not be limited to aspects of the disclosed embodiments, as Patent Owner proposes to do here. See, e.g., Ex. 1001, 2:56–59 (“The invention is described in connection with such embodiments, but the invention is not limited to any embodiment.

“But before describing the embodiments cited by Patent Owner, the Specification plainly states: “Any terms not expressly defined herein have their conventional meaning as commonly understood by those having skill in the relevant art(s).” Ex. 1001, 4:64–67. Thus, the Specification itself cautions against construing the claim terms such as “secure identifier” as limited to the scope of the disclosed embodiments. Here, Patent Owner has not cited any express definition of “secure identifier,” or identified any explicit disclaimer of claim scope that might justify narrowing the scope of this claim term to specific embodiments disclosed in the Specification. In the absence of such a definition or disclaimer, we are not persuaded that the scope of the claim term “secure identifier” should be limited to specific aspects of the preferred embodiments cited by Patent Owner. See Prelim. Resp. 7–14.

“’071 Application lack adequate written description support for the “secure identifier” claim limitation. For a patent claim to be entitled to the priority date of an earlier-filed application, the earlier application must provide complete written description support for the claim as required by 35 U.S.C. § 112(a). L.A. Biomedical Rsch. Inst. at Harbor-UCLA Med. Ctr. v. Eli Lilly & Co., 849 F.3d 1049, 1057 (Fed. Cir. 2017) (“L.A. Biomed”). To satisfy this requirement, the written description must “reasonably convey” to a person of ordinary skill in the art that the inventor had possession on the claimed priority date of each limitation of the later-claimed subject matter. L.A. Biomed, 849 F.3d at 1057. It is not enough that an earlier application’s disclosure “renders the later-claimed invention obvious;” as “the disclosure must describe the claimed invention with all its limitations.” L.A. Biomed, 849 F.3d at 1057. On this record, we agree with Petitioner that the ’153 Provisional and ’071 Application lack adequate written description support for the “secure identifier” limitation of claim 21. We have preliminarily construed “secure identifier” as “a credential that can be used to securely verify the identity of a device, such as an airborne object or ground-based transmitter.” See supra § II.B. As discussed above, the Specification of the ’959 Patent does not use the term “secure identifier,” but the Specification contains extensive discussion of the need for an identification credential that is secure (e.g., difficult for a bad actor to clone or impersonate). See, e.g., Ex. 1001, 1:56– 65 (discussing the need for a system that is difficult to “clone”), 10:20–49 (discussing the need “trust” between a drone and ground-based equipment, and the need for a way to verifying the drone’s credentials), 11:5–12:62 (disclosing the use of encryption and a rotating SSID to generate a secure identifier for a drone). None of the portions of the Specification cited above is present in the ’153 Provisional or the ’071 Application. See generally Ex. 1006, 1007. The ’153 Provisional and ’071 Application discuss the need for identifiers for low-altitude aircraft (see, e.g., Ex. 1006, 2; Ex. 1007, 9), but there is no discussion of any need for an identification credential to be secure or resistant to cloning or impersonation. See generally Ex. 1006, 1007. The ’153 Provisional and ’071 Application do not disclose the use of encryption, SSIDs (much less rotating SSIDs), or any other technologies for the purpose of verifying the authenticity of an identification credential. See generally id. Based on our review of the ’153 Provisional and ’071 Application, we preliminarily conclude that neither of these applications would have reasonably conveyed to a person of ordinary skill in the art that the inventor then had possession of the concept of the “secure identifier” that was later claimed in the ’959 Patent.” slip op. at 12

“using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same.” The Federal Circuit has held that “[t]he written description requirement is met when the disclosure relied on for support ‘reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.’” RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1088 (Fed. Cir. 2024) (quoting Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc) (citation omitted)). The written description inquiry is a question of fact, is context specific, and must be determined on a case-by-case basis. Ariad, 598 F.3d at 1351 (citing Ralston Purina Co. v. Far-Mar-Co, Inc., 772 F.2d 1570, 1575 (Fed. Cir. 1985); Capon v. Eshhar, 418 F.3d 1349, 1357–58 (Fed. Cir. 2005)). “[T]he level of detail required to satisfy the written description requirement varies depending on the nature and scope of the claims and on the complexity and predictability of the relevant technology.” Id. (citing Capon, 418 F.3d at 1357–58). Factors used to evaluate the sufficiency of a disclosure include: 1) “the existing knowledge in the particular field”; 2) “the extent and content of the prior art”; 3) “the maturity of the science or technology”; and 4) “the predictability of the aspect at issue.” Id. (citing Capon, 418 F.3d at 1359). As support for the term “memory space,” the ’612 patent explains that because “the SLC NAND flash is used to boost the lifetime (endurance) of the storage system, it can be considerably lesser in amount than the MLC NAND flash.” Ex. 1001, 5:20–23; see Ex. 2001 ¶ 51. As an example, the ’612 specification states that “a system may set SLC NAND flash equal to 12.5% or 25% of MLC NAND flash (total non-volatile memory storage space=MLC+SLC).” Ex. 1001, 5:23–25; see Ex. 2001 ¶¶ 51, 62. In addition, we find persuasive Dr. Khatri’s testimony that one of ordinary skill in the art would have understood that “there are two spaces—MLC and SLC—where data is stored, and the total memory space is the combination of the two.” Ex. 2001 ¶ 51. Further, the ’612 patent’s Figure 1 depicts “memory space,” e.g., dynamic random-access memory (DRAM) 20, one or more disks 24, MLC NAND flash memory module 26, and SLC NAND flash memory module 28. Ex. 1001, 5:37–45, Fig. 1; see Ex. 2001 ¶ 64. The ’612 patent’s Figure 4 also depicts “memory space,” e.g., NAND flash memory bank 56 comprising “a plurality of MLC NAND flash memory modules 60a and a plurality of SLC NAND flash memory modules 62a” and NAND flash memory bank 58 comprising “a plurality of MLC NAND flash memory modules 60b and a plurality of SLC NAND flash memory modules 62b.” Ex. 1001, 7:8–14, Fig. 4; see Ex. 2001 ¶ 64. On the record before us, we find the above noted disclosures to be sufficient to support the disputed claim language. For these reasons, the ’612 patent’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” See Ariad, 598 F.3d at 1351.” slip op. at 15

The Board instituted IPR on claims 1–8 on all asserted grounds, finding a reasonable likelihood that at least one claim would have been obvious over DiPerna964 and Strack.

“We determine below that Fintiv factors 1–5 do not favor discretionary denial. Thus, we do not reach the issue of whether the merits are compelling. CommScope Techs. LLC v. Dali Wireless, Inc., IPR2022- 01242, Paper 23 at 4–5 (PTAB Feb. 27, 2023) (precedential) (Board must first address Fintiv factors 1–5, and should engage the compelling merits question only if that analysis favors discretionary denial) (“CommScope”). 7. Balancing the Fintiv Factors Weighing against exercising our discretion to deny institution is factor 3 involving the parties’ limited investment and lack of substantive orders in the District Court litigation. Factor 4 concerning the limited overlap of the issues in the two cases also weighs against discretionary denial. Only factor 5, that Petitioner and the defendant in the District Court litigation are the same party, weighs in favor of discretionary denial. Factor 1 concerning the absence of a stay in the District Court litigation, and factor 2 concerning the close proximity between the start of trial in the District Court litigation and the estimated deadline for the final written decision, are neutral on the facts of this case. We therefore determine that the balance of factors 1–5 weighs against discretionary denial. Accordingly, we do not consider the issue of whether compelling merits have been shown under factor 6.

“Pet. 9 (citing Ex. 1006, 23) (emphasis added). From this passage, we understand the “safety” switch to be “separate” from the panic button, not a part of it. This understanding is reinforced by claim 7 which depends from claim 1 and recites that the mobile device “further compris[es] a safety switch,” meaning it is a separate element from the panic button. Ex. 1001, 9:3–4. Thus, moving the safety switch into position readies the panic button, which is not the same as the panic button readying itself to perform functions in claims 1–8 of the ’404 patent. Patent Owner does not sufficiently address this issue in its assertions. See Prelim. Resp. 5–7. Patent Owner’s reliance on disclosures elsewhere in the ’404 patent is likewise not persuasive. Prelim. Resp. 5–6. For example, the ’353 application mentions “ready” in relation to using a self-defense mechanism such as pepper spray, which has not been shown to be related to the panic button. Ex. 1006, 5, 9–10. Although Patent Owner relies on the ’353 application’s description of voice activation using a codeword, voice activation does not ready the panic button for activation to perform functions, but actually activates the panic button to perform those functions. Prelim. Resp. 6 (citing Ex. 1006, 17). Petitioner thus met its burden here to demonstrate that claims 1–8 of the ’404 patent lack written description support for a panic button adapted to “ready itself” to perform the recited functions because the limitation is not present in the ’353 application to which the ’404 patent claims priority. Pet. 8–10. The burden of production thus shifted to Patent Owner to demonstrate that the ’353 application has written description support for this limitation, which it has not done on this record. Prelim. Resp. 5–7.” slip op. at 17

“of the proceeding, we are persuaded that Petitioner has demonstrated a reasonable likelihood of prevailing on its assertions that at least one of claims 1–8 of the ’404 patent would have been obvious under 35 U.S.C. § 103 based on the ground set forth in the Petition. Accordingly, we institute trial for all challenged claims on all grounds asserted by Petitioner. See SAS Institute Inc. v. Iancu, 138 S. Ct. 1348 (2018). Our factual findings, conclusions of law, and determinations at this stage of the proceeding are preliminary, and based on the evidentiary record developed thus far. At this stage of the proceeding, we have not made a final determination with respect to the patentability of the challenged claims or to the construction of any claim term. V. ORDER For the foregoing reasons, it is ORDERED that, pursuant to 35 U.S.C. § 314(a), an inter partes review of claims 1–8 of the ’404 patent is hereby instituted on all challenges to patentability set forth in the Petition; and” slip op. at 31

“Petitioner has shown sufficiently that a POSITA would have combined DiPerna964 and Strack with a reasonable expectation of success. Pet. 16–18. DiPerna964 and Strack are directed to similar mobile devices for use in security and emergency situations. Id. at 16–17. Petitioner demonstrates sufficiently that a POSITA would have regarded Strack’s arming and timer technique as an improvement that would have been useful with DiPerna964’s mobile device (at least in some circumstances) to provide the user with additional time to evaluate whether triggering the 911 call is warranted. Id. at 17–18. This amounts to the use of a known technique to improve similar devices in the same way, which is a recognized rationale for combining prior art references. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 401, 417 (2007). Accordingly, on this record, Petitioner has presented a reasonable likelihood that a POSITA would have combined DiPerna964 and Strack with a reasonable expectation of success.
