Fintiv at 6. The trial date (December 2025) for the parallel proceeding is considerably earlier than the projected statutory deadline (June 2026) for issuing a final written decision in this proceeding. Accordingly, Fintiv factor 2 weighs for discretionary denial. Under Fintiv factor 4, there is significant overlap between the invalidity challenges asserted in the two proceedings. Petitioner has proffered no stipulation to ameliorate concerns of duplicative efforts and conflicting decisions. Accordingly, this factor weighs for discretionary denial. Petitioner and the defendant in the parallel proceeding are the same, so Fintiv factor 5 weighs for discretionary denial.” slip op. at 15

    • BurdenInstituted

      “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).”).

      “2026. This date is nearly five months prior to the date on which the final written decision would be due if trial were instituted in this proceeding. And, even if we assume Petitioner’s alleged February–March 2026 trial date, this date too is several months prior to the projected final written decision deadline. As such, it is unlikely that a final written decision in this proceeding would issue before trial in the district court, unless the trial was delayed or rescheduled for a later time.

      “II. ANALYSIS A. Level of Ordinary Skill in the Art Relying on the Schubert Declaration, Petitioner proposes that a person of ordinary skill in the art “would have had a bachelor’s degree in electrical engineering, physics, materials science, or a related discipline, and 6 years of 1 The Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112–29, 125 Stat. 284 (Sept. 16, 2011), includes amendments to Section 103 that became effective on March 16, 2013. Because the challenged claims issued from an application filed before March 16, 2013, we apply pre-AIA law.

Pet. 2. 3 US 2012/0050606 A1, published March 1, 2012 (Ex. 1005, codes (10), (43)) (“Debevec”). Petitioner asserts that “[b]ecause Debevec was filed prior to the priority date of the ’546 patent, it qualifies as prior art at least under pre-AIA 35 U.S.C. § 102(e).” Pet. 2. 4 US 6,774,584 B2, issued August 10, 2004 (Ex. 1008, codes (10), (45)) (“Lys”).

      “The “context” is typically evaluated by reviewing the intrinsic record. See e.g., Regeneron, 130 F.4th at 1380–84. Here, as discussed above, the ’546 patent has multiple disclosures where a curtain lamp has a single light-emitting diode in one light-emitting diode string. See Ex. 1001, 1:33–36, 6:15–20, 6:27–40, 8:25–45. In particular, the ’546 patent similarly discloses a first curtain lamp with one LED in one light string, as well as a second curtain lamp, which provides further support for Petitioner’s proposed interpretation. Id. at 8:25–45. Although Patent Owner argues that Figures 7 and 8 disclose multiple LEDs and light strings in curtain lamps, other embodiments and claims explicitly indicate single components in a “curtain lamp.” “[T]here is a strong presumption against a claim construction that excludes a disclosed embodiment.” See In re Katz Interactive Call Processing Patent Litig., 639 F.3d 1303, 1324 (Fed. Cir. 2011). Given that certain embodiments and claim 8 disclose a curtain lamp with one light string with one LED, we decline to interpret the claim to prohibit Petitioner’s interpretation. Additionally, we do not find that Petitioner’s claim interpretation renders the claim terms nonsensical or illogical. See Becton, 616 F.3d at 1255. Patent Owner asserts otherwise, arguing that Petitioner’s interpretation is based upon a “nonsensical” or “absurd[]” argument, there is no reason to have both a master and slave control unit to operate a single LED, and the interpretation renders most of the components superfluous. See PO Sur-reply 12; PO Resp. Supp. Br. 5. As discussed above, however, although the ’546 patent does not appear to provide any explanation for why there are master and slave control units to operate a single LED, the patent nevertheless discloses that in embodiments. This situation is also distinguishable from Becton, where “unequivocal language” of the claim recited “spring means ‘connected to’ the hinged arm,” such that interpreting the spring means and the hinged arm as the same structure would have rendered the claim nonsensical. Becton, 616 F.3d at 1254–55. Becton further found that interpreting the spring means and hinged arm as the same structure would be inconsistent with descriptions of the elements in the specification. Id. Here, in contrast, the ’546 patent Specification is replete with disclosures of a curtain lamp having one light string with one LED, and claim 8 is directed to the same. Accordingly, we adopt Petitioner’s interpretation of these claim elements.” slip op. at 36

    • Strike new argumentNew argument consideredDecided for petitioner

      “Although Patent Owner argues that Petitioner’s arguments in the Reply on “light strings” and “curtain lamp” as they relate to a single LED are improper, we do not agree. As Patent Owner acknowledges, the Petition and Dr. Schubert’s original declaration stated that a “curtain lamp” is “commonly understood to be one or more light strings.” See PO Sur-reply 12; see also Pet. 8; Ex. 1003 ¶ 37. Patent Owner did not contest Petitioner’s interpretation in its Response. See PO Resp. 15. Patent Owner did, however, argue that Kuang did not teach or suggest “light strings” in any form and therefore did not teach a “curtain lamp” under Petitioner’s definition of the same. PO Resp. 15–17. A petitioner reply may respond to arguments raised in a patent owner’s response under 35 U.S.C. § 42.23(b), and here Petitioner’s argument that a light string may have a single LED is properly presented in its Reply in response to Patent Owner’s arguments. Further, Patent Owner was not only aware that Petitioner had taken the position that a “curtain lamp” could be a single “light string,” but Patent Owner also did not dispute Petitioner’s interpretation.8 Our view, therefore, is that Petitioner’s argument that a curtain lamp may be a single LED is proper because it is corollary to Petitioner’s reply arguments on light strings. That is, Petitioner’s assertion follows from the reply arguments on light strings and the unopposed interpretation of curtain lamp as a single light string. Additionally, to the extent there could be any prejudice to Patent Owner by these light string and curtain lamp arguments, Patent Owner has had opportunities to address them by supplemental briefing.” slip op. at 32

Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts.

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.

      “This disclosure is inconsistent with any suggestion that the Fangman system, when routing a telephone call to its destination, identifies the private IP address of the destination telephone by determining the port range to which the port number of the destination telephone belongs. When Fangman describes the NAPPT process, it does not indicate that port ranges are used, but rather repeatedly states that port numbers are used: The [service gateway] receives a data packet from the IP device, including a public destination IP address . . . a destination port number . . . and source information, NAPPTs the data packet, using the [public destination IP address] and the [destination port number] to identify the [IP telephone] . . . . Ex. 1024, code (57). Performing NAPPT on the data packet received from the destination may include using the public destination IP address and the destination port number to uniquely identify the IP telephone, and changing the public destination IP address to a private source IP address of the IP telephone while leaving the destination port number unchanged. Ex. 1024, 4:28–33. The SG 170 may maintain a table of semi-permanent mappings of the external IP address and ports to the internal hosts and ports. Ex. 1024, 8:49–51.” slip op. at 33

      “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. Because Petitioner ranks the instant Petition higher than the ’68 Petition, we decline to discretionarily deny this Petition due to Petitioner’s filing of the ’68 Petition.” slip op. at 10

      “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.

      “Patent Owner argued that we should not institute both petitions. Paper 8, 1–5. Patent Owner argued that the challenged claims are not long and Petitioner’s concerns about the construction of “association” in limitation 1(b) are “contrived.” Id. at 1. Patent Owner contends that Petitioner could have addressed all of the challenged claims in one petition. Id. Noting that both the ’70 petition and the instant Petition challenge all claims of the ’872 patent, Patent Owner argued that the number of claims challenged does not necessitate multiple petitions. Id. at 2–3. Patent Owner also argued that Petitioner could have waited until closer to the statutory due the claim language “association” in the related district court proceeding. Id. at 4–5. Considering the facts holistically, we determine the totality of the circumstances here supports Petitioner’s position that two petitions are warranted. Petitioner has challenged a large number of claims directed to complex subject matter. And the task of challenging those claims is complicated by the potential for Patent Owner to argue for a narrow construction of “association” in limitation 1(b). Patent Owner’s suggestion that Petitioner would not have needed to file multiple petitions if it had waited longer to file a petition is not persuasive. Paper 8, 4–5. Patent Owner does not explain why a petitioner should be encouraged to delay the filing of its petition. See id. And the parties appear to agree that Patent Owner has not weighed in on whether “association” should be interpreted narrowly or broadly. Prelim. Reply. 8; Prelim. Sur-Reply 8. The present circumstances, considered as a whole, warrant two petitions challenging the claims of the ’872 patent.” slip op. at 10
