“based on Petitioner’s first stipulation filed on December 18, 2024.15 Prelim. Resp. 13–15. Patent Owner does not address Petitioner’s updated second stipulation filed on April 8, 2025. This updated second stipulation mitigates any concerns of duplicative efforts between the district court and the Board, as well as concerns of any potentially conflicting decisions. See Sand at 12. We therefore find that this factor weighs against exercising discretion to deny institution. See id., n.5. 5.

“c) Conclusion Regarding Claim 1 Based on the current record, we determine that there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 1 is unpatentable as obvious over the combination of Mazumder and Mori. Accordingly, we institute inter partes review with respect to all claims and all grounds asserted in the Petition. 5. Claims 3, 5–7, 9, 10, and 19–22 Because Petitioner demonstrates a reasonable likelihood of success in proving that at least one claim of the ’324 patent is unpatentable, we institute on all grounds and all claims raised in the Petition. See 37 C.F.R. § 42.108(a). Therefore, at this stage of the proceeding, it is not necessary for us to provide an assessment of every challenge raised by Petitioner, especially, as in this case, when Patent Owner does not separately argue those claims. See Prelim. Resp. 28–46. Those challenges, in our view, are best left for trial after full development of the record.” slip op. at 27

Patent Owner argues that “it is hindsight to use ‘the invention to define the problem the invention solves.’” Prelim. Resp. 43 (quoting Mintz v. Dietz & Watson, Inc., 679 F.3d 1372, 1377 (Fed. Cir. 2012); citing AT&T Services Inc. et. al. v. Innovative Sonic Ltd., IPR2024-001143 (PTAB Feb. 11, 2025)). According to Patent Owner, because neither Mazumder nor Mori teaches visual comparison of image types, the idea to improve the Mazumder-Mori combination by simultaneously displaying different image types and thus permitting visual comparison must be driven by hindsight. Id. at 44–45. But Petitioner cites evidence other than the ’324 patent to support the person of ordinary skill in the art having a desire to visually compare the different images presented in the Mazumder-Mori combination. Pet. 23–24 (citing Ex. 1003 ¶ 113). Specifically, Dr. Wolfe testifies that “the presentation of the actual images captured by the camera and the virtual images simultaneously within the user interface would have beneficially aided the remote user to more easily visually compare the actual image and virtual image to quickly identify any defects or problems with the fabrication process” and that a person of ordinary skill in the art would have recognized this. Ex. 1003 ¶ 113. Thus, Petitioner has shown sufficiently for the purpose of the present decision that Mori teaches or suggests the disputed limitation of claim 1.

“In this case, Mr. McAlexander meets both Petitioner’s and Patent Owner’s proposed level of skill in the art. As a result, we are persuaded Mr. McAlexander has the requisite skill and relevant expertise to offer testimony in this matter. For example, Mr. McAlexander has a Bachelor’s Degree in Electrical Engineering and far more than 2 years of experience in the electrical engineering field. Ex. 1027, 3–6, 7. In addition, Mr. McAlexander has provided expert consulting services in a wide range of technology areas involving the process and design of electro-mechanical consumer products. Ex. 1003 ¶ 5. Through one of Mr. McAlexander’s business ventures, his laboratory has “performed detailed airflow analyses, designing and constructing specialized apparatuses to emulate human breath, allowing for precise activation testing of ENDS devices.” Ex. 1043 ¶ 16. That said, a declarant’s expertise, even clothed as a skilled artisan, does not entitle a naked opinion persuasive weight. Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985). Here, Patent Owner had the opportunity to, and in fact did, thoroughly cross examine Mr. McAlexander about the purported deficiencies in his testimony. See, e.g., Exs. 2052, 2054; Daubert v.

“We are persuaded by Petitioner’s arguments and evidence. Fuloria teaches “a mechanism for user to promote social networking objects to other users.” Ex. 1004 ¶ 1. Fuloria displays a news feed containing social media content items. Id. at code (57), ¶¶ 6, 27. Users in Fuloria may like a piece of content or “for a given price” the user may turn their like into a “super-like.” Id. ¶ 37. “The ‘super-liked’ story is priced and directed toward users in a similar manner as a social ad. In particular embodiments, sponsored story system 304 may also add a weight to the story to alter its direction toward users.” Id. ¶ 39. Petitioner argues that “[t]his functionality represents uncapped engagement . . . because Fuloria places no limitation on how many times a user can super-like a piece of content.” Pet. 24–25. Dr. Bederson supports Petitioner by noting that Fuloria does not “place any limitation on how many credits a user can spend to increase the reach of the content.” Ex. 1002 ¶ 76. Further, Dr. Bederson states that “[m]ultiple different users can also promote the same content item. By allowing users to promote or ‘super-like’ content which also increases engagement with that content by other users, Fuloria’s system also facilitat[es] uncapped engagement with that content.” Id. ¶77. We find these arguments to be persuasive. The ’687 patent states that “[s]o long as the user has sufficient resources, the user may promote herself or others with uncapped (i.e., unlimited) engagements, which may facilitate getting noticed by other users, whether with respect to a social media content item.” Ex. 1001, 2:6–10. Similarly, Fuloria allows users to expend their resources and to have the super-like displayed according to the amount paid for the super-like. Ex. 1004 ¶ 57 (“In particular embodiments, the advertisement system adjusts the display of the ‘super-liked’ story based upon social factors as well as the real-world value of the credits paid.”); see also id. ¶ 38 (“[T]he social networking system may deduct the credits based on a cost per impression (CPM), effective cost per impression (eCPM), cost per click (CPC), or cost per action (CPA) pricing model”). Fuloria teaches likes from any number of users which is argued to disclose the multiple users recited in the claim. See Ex. 1002 ¶ 82 (discussing Fuloria’s display of engagement by a user and pointing out that Figure 9A shows 1,884 likes); see also id. ¶ 87 (“Fuloria teaches that ‘super-likes’ are available to users in general (and thus to first, second, third, etc. users).”).

“Patent Owner argues, and Petitioner does not dispute, that an aperture is a “hole” or an “opening.” See, e.g., id. at 21; see generally Reply. Patent Owner asserts that, in the proper context, the plain and ordinary meaning of a housing having an aperture is that the aperture is a hole, or an opening, on the housing structure itself. Id. at 21–22. We agree. In order for an object to have an “aperture” or an “opening,” the aperture or opening must be on the structure itself and not on a separate object that is located in the structure. This construction is in accord with the Specification of the ’864 patent, which refers to apertures in context of the structure on which they are located. See, e.g., Ex. 1001, 6:12–18 (referring to a first end comprising a first aperture), 7:11–12, 7:65–67 (stating that the wall of an airflow passageway may have apertures).” slip op. at 18

“large obstructions that force the air flow to near the peripheral surface of the housing, render the passageway non-central. During prosecution of the ’864 patent, the Examiner rejected certain claims (i.e., dependent claims 49, 63, and 75) over Han. To overcome this rejection, the applicant argued that Han cannot meet the limitation “wherein the airflow passageway extends centrally and axially from the first aperture to the second aperture.” Ex. 1002, 273. The applicant explained that Han does not meet this limitation because Han’s shell (b) does not include a central airflow passageway and instead places the perforated component for liquid storage (9) in the middle of shell (b), thereby forcing the airflow around the peripheral surface of the perforated component for liquid storage (9). Id. at 273–274. The examiner relied on this argument in determining that the applicant had overcome an earlier rejection. Id. at 195. Thus, some obstructions of a passageway render the passageway non-central; in particular those obstructions that force air to flow near the peripheral surface of the housing are large enough to render the passageway non-central.” slip op. at 22

“Patent Owner argues, however, that this presumption is overcome in the present case, and we agree. PO Resp. 28–32. We note that, although the claims require the first aperture to be “on the first end,” the claims still require that the “housing hav[e] a first aperture.” Thus, the issue is whether the aperture must be on the housing itself or part of the housing, as well as whether the aperture is on the first end of the housing. Although “having” and “includes” are used with respect to the solution holding medium to refer to elements located inside the housing, the specification of the ’881 patent suggests that the ends of the housing are part of the housing itself, rather than located inside the housing. First, “the first end . . . can be integrated into a single assembly as part of the housing.” Ex. 1001, 6:16–17. Second, “the housing . . . may comprise the cylindrical wall and two end-caps,” or “the housing . . . may comprise the cartridge wall and a single end-cap.” Id. at 3:55–59. The only figures of the ’881 patent that depict first end 206 show it at the end of the housing rather than located within the interior of housing 202. Id. at Figs. 2, 3. Moreover, there is no requirement to construe a claim term uniformly across multiple uses in the claims when doing so would be nonsensical. Microprocessor Enhancement Corp. v. Texas Instruments, Inc., 520 F.3d 1367, 1375 (Fed. Cir. 2008). Here, construing a first element that is recited as “having” or “includ[ing]” a second element always as encompassing not only second elements that are part of the first element, but also second elements that are located within the interior of the first element, would lead to nonsensical results. Claim 2 recites an airflow passageway “having a length having a circular cross section.” Ex. 1001, 17:59–60. It would be nonsensical to interpret this claim as encompassing an airflow passageway of non-circular cross section that contains another object that has a circular cross section, and neither party argues in favor of such a reading. Similarly, claim 16 recites an “airflow passageway having an interior having a uniform cross-sectional area,” and there is no reason to interpret this claim as encompassing an airflow passageway of non-uniform cross-sectional area that contains another object that itself has uniform cross-sectional area. Id. at 19:47–48. Thus, the claims do not use “having” or “includes” consistently to refer to elements located within the interior of an object; instead, they sometimes use these terms to refer to elements that are a part of an object. See Epcon Gas Sys., Inc. v. Bauer Compressors, Inc., 279 F.3d 1022, 1030–31 (Fed. Cir. 2002) (terms should be construed based on the context of how the terms are used in the claims).” slip op. at 13

“2. Factor 2: ITC Final Determination Date Fintiv provides that an ITC trial date that is earlier than the Board’s projected statutory deadline for a final written decision may favor discretionary denial if the ITC is going to decide the same or substantially similar issues to those presented in the petition. Fintiv, Paper 11 at 8. The Guidance Memo further provides that “the Board is more likely to deny institution where the ITC’s projected final determination date is earlier than the Board’s deadline to issue a final written decision.” Guidance Memo 2. Here, the ITC has set the target date for its final determination to March 2, 2026. Ex. 2010, 3 (ITC Order Amending the Procedural Schedule).

“Under 35 U.S.C. § 314, 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.” Upon consideration of the Petition in view of the present record and for the reasons explained below, we determine that Petitioner has not shown a reasonable likelihood of prevailing with respect to at least one of the challenged claims. Accordingly, we do not institute an inter partes review on the grounds set forth in the Petition. See 37 C.F.R. § 42.108(a).” slip op. at 2

“We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification describes only fingerprint creation outside the virtual machine monitor because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. See Sur-reply 1– 2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter. Last, Petitioner’s characterization of Patent Owner’s infringement allegations in the related district-court proceedings, even if correct, do not undermine the claim’s plain language.” slip op. at 9

“Petitioner does not contest that Capalik’s fingerprint generation occurs outside the components that Petitioner identifies as the claimed virtual machine monitor. Reply 1–3; see Pet. 18–23 (mapping Capalik’s hypervisor kernel 516 to the claimed virtual machine monitor); id. at 30–31 (mapping Capalik’s processing module 508 and signature generation engine 530 to the claimed fingerprint creation); see also Prelim. Resp. 21–23 (explaining Petitioner’s mapping). Instead, Petitioner asserts that the at-issue claim language—“at the virtual machine monitor”—does not require “that each of the subsequently recited steps must be performed by or in the [virtual machine monitor],” but instead only requires “that the fingerprint is generated by the same decoy system that contains the [virtual machine monitor].” Reply 2. Petitioner argues that the intrinsic record supports its position because “[n]owhere in the ’697 Patent is there any teaching or suggestion that a [virtual machine monitor] creates a fingerprint/signature indicative of attack activity,” and instead, “[t]he ’697 Patent teaches that its signature generation engine is separate from the [virtual machine monitor].” Reply 2 (citing Ex. 1001, 8:12–19).

“Given the deficiencies outlined above, Petitioner has not shown that the prior art teaches or suggests creating a fingerprint at the virtual machine monitor as the challenged claims require. Thus, Petitioner has not shown a reasonable likelihood of prevailing with respect to at least one of the challenged claims. III. CONCLUSION After considering the evidence and arguments presented in the current record, we determine that Petitioner has not demonstrated a reasonable likelihood of success in proving that at least one of the challenged claims of the ’697 patent is unpatentable. We therefore do not institute trial on any challenged claims or grounds raised in the Petition.” slip op. at 10

“MULTIPLE PETITIONS CHALLENGING THE ’872 PATENT In addition to challenging the claims of the ’872 patent with the instant Petition, Petitioner filed a petition in IPR2025-00068, which also challenged claims of the ’872 patent. IPR2025-00068, Paper 1 (“the ’68 Petition”). Petitioner ranked the instant Petition first and the ’68 Petition second. Paper 3, 5. Arguing that the circumstances here do not warrant two petitions, Patent Owner suggests that we discretionarily deny the instant Petition, stating that “[i]f the Board is inclined to institute either of [Petitioner’s] Petitions, [Patent Owner] respectfully submits the Board should institute IPR2025-00068.” Paper 8, 5.

“We first look to the claim language itself. It recites “transmitting to one or more computer systems,” not transmitting to “devices.” Ex. 1001, 19:53. Although the claim language “one or more computer systems” may encompass “protected network devices,” we do not see a reason that its plain meaning would be limited to network devices, much less protected network devices. Nor do we see a reason that the plain meaning of “one or more computer systems” is limited to protected network devices to the exclusion of a network that includes protected network devices and one or more other components. In support of its suggestion that the claim language “one or more computer systems” excludes a combination of protected network devices and one or more other components, Patent Owner cites the claim language “for preventing future attacks, to the one or more computer systems.” Prelim. Resp. 20–24; Prelim. Sur-Reply 1–2. But Patent Owner does not provide reasoning or evidence persuading us to read the claim language more narrowly than its plain meaning, which encompasses preventing future attacks to a computer system that includes both protected network devices and one or more other components.” slip op. at 13
