An inter partes review may be instituted if “the information presented in the petition filed under section 311 and any response filed under section 313 shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a).

Patent Owner at this stage of the proceeding does not provide an alternative definition for a level of skill in the art that one would have had at the time of the invention of the ’527 patent or identify any shortcoming in Petitioner’s formulation. See Prelim. Resp. 3–4. For purposes of this Decision on Institution, we adopt Petitioner’s definition of the level of skill for one of ordinary skill in the art. Pet. 12. We view the definition for the level of ordinary skill is consistent with the ’527 patent and the asserted prior art, and we apply it in our analysis below.” slip op. at 6

Petitioner identifies where the combination of Kim, Dahlman, and Kim966 teaches these limitations, supported with testimony from Dr. Mandayam, which Patent Owner does not specifically rebut at this stage. We determine, on this record, that the combination of Kim, Dahlman, and Kim966 teaches the preamble (whether or not limiting) and the remaining undisputed limitations of claim 1. See LG Elecs., Inc. v. Conversant Wireless Licensing S.A.R.L., 759 F. App’x 917, 925 (Fed.

We also find that Petitioner has provided sufficiently articulated reasoning, which Patent Owner does not specifically address at this stage, to support combining Kim, Dahlman, and Kim966’s teachings in the manner Petitioner does. Pet. 21–38. 3. Summary In summary, based on the current record, we determine that Petitioner shows a reasonable likelihood that the combination of Kim, Dahlman, and Kim966 renders claim 1 obvious.” slip op. at 16

      “institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355–56 (2018). Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented demonstrates a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’110 patent.

      “measurement value, as Jover teaches.” Id. (citing Ex. 1005 ¶¶ 39–40; Ex. 1003 ¶¶ 115–30). Among other reasons, Petitioner contends that a POSITA would have been motivated to combine “to improve the accuracy and reliability of the beam failure determination.” Id. at 37 (citing Ex. 1003 ¶¶ 115–30). Petitioner further contends that a POSITA would have had a reasonable expectation of success because “it would have been straightforward for a POSITA to implement Jover’s triggering condition in Xia’s method.” Id. at 38 (citing Ex. 1003 ¶¶ 115–30). After considering Patent Owner’s arguments, which we address below, we agree with Petitioner at this stage that the combination of Xia and Jover renders obvious limitation [1e]. Patent Owner first argues that Jover “does not cure the deficiencies of Xia because Jover’s threshold condition for an increase in BER is not used for triggering a transmission of the first and second radio signal.” Prelim. Resp. 20. Just like Xia, Patent Owner contends, Jover discloses no “causality between the threshold being exceeded and transmitting the first and second radio signal.” Id. at 21. This argument does not undermine Petitioner’s showing at this stage because Petitioner relies on Xia, not Jover, for the claimed “triggering the transmission,” or “causality,” as Patent Owner calls it. See Pet. 36–38. That is, Petitioner relies on Jover for the triggering condition and on Xia for the actual triggering. See id. Patent Owner’s argument attacking the references individually is unpersuasive. See In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of refences.”). Patent Owner next contends that one of ordinary skill in the art would not have combined Xia and Jover “since Jover is directed to the opposite objective of the ’113 Patent or Xia.” Prelim. Resp. 21. That is, Patent Owner asserts, Jover teaches away from the disclosed methods. Id. at 22. Patent Owner explains, “Jover provides no attempt to improve the beam strength, but rather ignores it through beam sweeping or nullif[ies] it, in contrast to the purpose of the ’113 Patent.” Id. at 22–23. At this stage, Patent Owner’s argument is insufficient to undermine” slip op. at 15

First, Patent Owner contends that “indexes of antenna port groups with RSRP measurement values higher than a certain threshold are not a sequence of ratios,” but rather, just an identification of antenna port groups. Id. (emphasis added). We disagree, on this record. The flaw in this reasoning is that the claim does not require the first proportional sequence to be a sequence of ratios. Rather, the claimed “first proportional sequence” merely “corresponds to . . . ratios.” Thus, Patent Owner’s argument that the indexes “are not a sequence of ratios” is not commensurate with the scope of the claim.

      “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. The scope of the invention is limited only by the claims . . . .”) Patent Owner additionally fails to cite any lexicographic definition or clear and unambiguous disclaimer of claim scope sufficient to limit the claims in the manner it proposes. We, thus, are not persuaded that the Detecting Limitations require “applying aboard the reference UAV a machine learning model to the capture image for: (i) identifying a target in the captured image.”” slip op. at 8

      “permission module,” as used in claim 1, has “a well understood structural meaning in the computer technology field.” 792 F.3d at 1350. Rather, the limitation in question is “drafted in the same format as a traditional means-plus-function limitation, and merely replaces the term ‘means’ with ‘nonce’ word ‘module,’ thereby connoting a generic ‘black box’ for performing the recited computer-implemented functions.” Id. And, while claim 1 recites the “outputs” of the permission module (i.e., a determination regarding the permissions of an aerial system), “the claim does not describe how the [permission module] interacts with other components in the [discrimination system] in a way that might inform the structural character of the limitation- in-question or otherwise impart structure to the [permission module] as recited in the claim.” Id. at 1351. We also reviewed the Specification, and we agree with Petitioner that the Specification identifies the following structure as corresponding to the claimed permission module: “storage on-board the disruption module 105, storage on-board the identification receiver 102, a remote computing system connected to the disruption module…, or [] any other suitable computing system.” See Pet. 12; Ex. 1001, 9:64–10:4. slip op. at 7

      “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. On this record, and at this stage of the proceeding, we decline to adopt Patent Owner’s proposed construction and preliminarily construe “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.”8” slip op. at 10

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateDecided for petitioner

      “’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
