“The Board has recently clarified that “[s]imply noting that the petitioner is adopting a patent owner’s claim construction proposals from district court . . . is not a sufficient reason for advancing different positions in the two forums.” Revvo Techs., Inc. v. Cerebrum Sensor Techs, Inc., IPR2025-00632, Paper 20, 5 (PTAB Nov. 3, 2025) (precedential). In Revvo, as in this case, the petitioner did not propose its own constructions for claim terms in the Petition, but instead accepted the patent owner’s proposed constructions from the related district court litigation. Id. at 2. Although the petitioner had proposed different constructions for the claim terms in district court, it did not explain why it was taking a different position before the Board. Id. The Board’s trial rules “do not necessarily prohibit petitioners from taking inconsistent claim construction positions before the Board and a explain why alternative positions are warranted.” Revvo, Paper 20, 3–4 (quoting Cambridge Mobile Telematics, Inc. v. Sfara, Inc., IPR2024-00952, Paper 12 at 8–9 (PTAB Dec. 13, 2024) (informative)). Petitioner has not sufficiently done so here. Moreover, the fact that Petitioner cannot raise its indefiniteness challenge in an inter partes review is not a sufficient reason to allow Petitioner to take inconsistent claim construction positions before the Board and the district court. Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025- 00340, Paper 18, 3 (Nov. 5, 2025) (informative). As explained in the Board’s Tesla decision: Petitioner’s statement that it cannot raise indefiniteness challenges in an inter partes review is not a sufficient explanation. Indeed, the statement amounts to an assertion that a petitioner should be permitted to raise inconsistent invalidity challenges in the two forums. Petitioner’s explanation may have risen to a sufficient level, for example, if Petitioner had shown that, notwithstanding the alleged indefiniteness of the claim term, an ordinarily skilled artisan would understand that the asserted art satisfies the claim limitation (such as if the limitation prescribed a range and only the outer bounds of the range were unclear). Instead, Petitioner argued indefiniteness in the district court and then adopted Patent Owner’s plain and ordinary meaning construction from the district court litigation in its Petition.

“We determine that Petitioner cannot credibly certify that the ’418 patent is available for inter partes review, based on a claim of priority on the face of the ’418 patent to the ’939 provisional application filed prior to the effective date of the AIA, where, as here, Petitioner contradictorily contends in the Petition that the ’939 provisional application “does not support all claim limitations” of the ’418 patent.4 Id. If Petitioner’s allegation that claims of the ’418 patent are not supported by the ’939 provisional application is correct, then the ’418 patent would be a post- AIA patent for which a petition may not be filed earlier than 9 months after the ’418 patent issued. See 35 U.S.C. § 311(c). Thus, based on the arguments and evidence presented by Petitioner, Petitioner fails to show that the ’418 patent is eligible for inter partes review when Petitioner filed the Petition less than two months after the ’418 patent issued. 35 U.S.C. § 311(c), 37 C.F.R. § 42.102(a)(1).

Based on the current record, we determine that no claim term requires an explicit construction to decide whether Petitioner satisfies the “more likely than not” standard for instituting a post-grant review. As Petitioner recognizes, the ’149 patent defines many of the claim terms Petitioner discusses in the “Claim Interpretation” section of the Petition. See Pet. 14–16. For instance, the patent defines “antenna rectangle” as “the orthogonal projection of the antenna box along the normal to the face with largest area of the antenna box.” Ex. 1005, 14:21–24. Further, the patent defines “complexity factor F21” and “complexity factor F32” consistent with the independent claims.

“Petitioner does not explain why an ordinarily skilled artisan who used Ciais-Quadband’s antenna for Dou’s two antennas 206 and 208 would have departed from the commonly accepted rule of thumb and Dou’s preference for at least a quarter-wavelength spacing between antennas at the lowest frequency to the extent needed to implement the proposed combination, i.e., with only about 55% of the preferred spacing between antennas. See Pet. 60–69; Ex. 1007 ¶¶ 172–187. Hence, based on the current record, Petitioner does not establish sufficiently for purposes of institution that an ordinarily skilled artisan would have been motivated to combine Ciais-Quadband’s teachings with Dou’s teachings in the way Petitioner proposes.

“generally known in the art, and that this is acknowledged by the ’853 patent. Pet. 40–41 (citing, e.g., Ex. 1001, 15:40–44). Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks. In either event, Petitioner has not sufficiently established that the proposed combination satisfies the “fractal includes a representation of the object based on landmarks” limitation of claim 1.” slip op. at 11

“Claim 1 explicitly recites “partially,” not “fully” or “completely.” On its face, “partially” appears to have its plain and ordinary meaning, i.e., not completely. The use of “partially” in the subject limitation shows or at least strongly suggests that the claimed invention contemplates at least some frequency gap to remain between the first channel and the second channel. In addition, as argued persuasively by Patent Owner, this interpretation is further supported by claim 1’s requirement of “transmitting data subcarriers occupying the first channel, the second channel, and the frequency gap in parallel to a receiver”: [T]he “transmitting” step in claim 1 requires that the frequency gap be included in the transmitted signal. Inclusion of the frequency gap in the transmitted signal necessarily requires that the frequency gap be only partially filled -- but not fully filled -- with added data subcarriers at the time of transmission, because if the frequency gap were fully filled it would no longer exist at the time of signal transmission.

“We agree with Patent Owner that Petitioner fails to offer sufficient explanation as to why a person of ordinary skill in the art would have combined the teachings of Sapuntzakis and Holzmann. Rather, Petitioner appears to argue that, based on the advantages described by Holzmann (Ex. 1007 ¶ 33), and using well-known techniques with unspecified predictable results, a person of ordinary skill in the art would have had sufficient reason to combine these disparate elements taught in the prior art references to render the challenged claims obvious. Pet. 23–24, 33. Yet, other than Petitioner’s cursory assertion of advantageously incorporating the memory module from Holzmann to provide a caching mechanism (Pet. 33), which cites equally cursory and unsupported testimony by Dr. Zadok (Ex. 1003 ¶¶ 329, 333, 336–355), Petitioner fails to identify what particular advantages or efficiencies would have prompted a person of ordinary skill in the art to combine Holzmann’s memory module with Sapuntzakis’s system.” slip op. at 29

“We find Patent Owner’s argument to be persuasive. Petitioner does not explain adequately how Bruner discloses the positional requirement of a subscriber access unit being coupled between the satellite dish and the router. Accordingly, Petitioner has not shown sufficiently for purposes of institution that Bruner anticipates independent claim 24. Although, for the obviousness challenge, Petitioner contends that Clark discloses a wireless router (for limitation 24c), Petitioner relies solely on Bruner for the “between” limitation. See Pet. 17 (“Bruner and/or Bruner in view of Clark both disclose each limitation of claim 24c, including a router (e.g., Bruner’s ‘ADS’ and Clark’s ‘wireless router’)”); id. at 18–19 (the discussion of the “between” limitation 24d asserting that “Bruner discloses claim 24d,” with no mention of Clark). Furthermore, Petitioner merely asserts that both Bruner and Clark disclose a router. See id. at 17–18. Petitioner, however, does not indicate clearly which is used in the proposed combination, does not describe the configuration of a proposed combination or a proposed modification of Bruner’s system, and fails to set forth an adequate and persuasive reason with rational underpinning as to why a person of ordinary skill in the art would have modified Bruner’s system to arrive at the positional requirement of the subscription access unit being coupled between the satellite dish and a router. See id. at 13–14 (motivation section for this ground); id. at 18–19 (addressing the “between” limitation 24d).

“Petitioner contends that: A person of ordinary skill in the art (“POSITA”) relevant to this patent at the time of its invention would’ve had a bachelor’s degree in computer science, computer engineering, or a related technical field, combined with approximately two years of practical experience in fields of networking such as network virtualization, security, or management. Additional professional experience might substitute for less education and vice versa. Pet. 10–11 (citing Ex. 1011 ¶¶ 33–35). Patent Owner, at this stage, does not disagree or propose a different definition of the person of ordinary skill in the art. However, Patent Owner’s proffered declarant, Dr. Noubir, opines that “a person of ordinary skill in the art in March 2003 would have a bachelor’s degree in computer science or electrical engineering, and would have one or two years of experience in computer networking or equivalent educational and professional experience.” Ex. 2008 ¶ 53. We discern no material difference between the two definitions. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art).

“name.” See Pet. 11–16 (claim construction section). Patent Owner asserts that “a person of ordinary skill would read ‘a domain name’ in its ordinary networking sense: an ASCII string label used with the Domain Name System (DNS) to resolve to an IP address.” Prelim. Resp. 16 (citing Ex. 1001, 1:47–48; Ex. 2008 ¶ 37). This is consistent with the Specification, which explains: Users and software applications do not always refer to hosts or other resources by their numerical IP address. Instead of using numbers, they use ASCII strings called domain names. The Internet uses a Domain Name System (DNS) to convert a domain name to an IP address. Ex. 1001, 1:45–50. According to the Patent Owner, the network in the Specification of the ’785 patent is defined by the domain name X.VCN. Id. at 33 (citing Ex. 1001, 9:18–19, 9:28–31). Patent Owner further contends that “[t]he use of a domain name to define the virtual network in the ‘785 Patent’s claims provides more than an identifier of the virtual network or even a plain language identification of an IP address – it signifies a hierarchical structure for the virtual network that enables [certain functions].” Prelim.

“We agree with Patent Owner, however, that Petitioner has not explained adequately why a person of ordinary skill in the art would have further modified the Caronni-I/Caronni-II combination to have DNS capability or why a person of ordinary skill in the art would have combined the three references to have a system that returned the three specific addresses recited in the challenged independent claims. Rather than explaining the “why,” the Petition’s motivation argument focuses on the purported capabilities of the resulting combination and implying, but not explicitly stating, that the combination results in the claimed subject matter; this indicates impermissible hindsight. See, e.g., id. at 29 (“This integration would leverage Hipp’s DNS capability for virtual hostnames to return multiple address records from a single query, aligning with the dual addressing requirements of hybrid virtual/physical networks. The combination creates a cohesive system where DNS resolution triggers context-aware routing decisions—using virtual addresses for internal Supernet traffic and NAT-translated addresses for cross-boundary communication.”). We determine that Petitioner has failed to set forth an adequate and persuasive reason with rational underpinning as to why a person of ordinary skill in the art would have combined the three references’ teachings to arrive at the claimed subject matter where the three recited addresses are returned in response to a DNS request.” slip op. at 21
