We discern no meaningful difference between the definitions proffered by Petitioner or its Declarant. Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’844 patent, the background technical field, the prior art, and Dr. Zadok’s unopposed definition of the ordinarily skilled artisan (Ex. 1003 ¶ 35), which is adopted by Dr. Newman (Ex. 2014 ¶ 13) and is consistent with the asserted prior art references, we apply the level of skill set forth by Dr. Zadok.” slip op. at 13

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.

      “To establish a motivation to combine multiple prior art references, it is not necessary to identify some deficiency in the primary reference that can only be remedied by combining that reference with another. The proposed the primary reference. See, e.g., Honeywell Int’l Inc. v. 3G Licensing, S.A., 124 F.4th 1345, 1355–56 (Fed. Cir. 2025) (Obviousness “does not require that a particular combination must be the preferred, or the most desirable, combination described in the prior art in order to provide motivation for the current invention.”); see also KSR, 550 U.S. at 420 (“[T]he problem motivating the patentee may be only one of many addressed by the patent’s subject matter.”). The relevant question is not whether the proposed combination is the most desirable combination available. Rather, it is “whether there is something in the prior art as a whole to suggest the desirability, and thus the obviousness, of the claimed invention.” Honeywell, 124 F.4th at 1355 (citations omitted). Here, Petitioner has identified reasons why it would have been desirable to modify the system of Brooks to include the texted URL link of SARLOC: the caller would not need any special technical skills or equipment; existing smartphone functionality would be capable of collecting the location information; and SARLOC simply represents a specific example of a general concept taught in Brooks, that of exchanging location information through text messages. Pet. at 38–39. Because the claimed modification need only be a suitable option, rather than the “best” or “preferred” approach, Patent Owner’s argument is unpersuasive.” slip op. at 14

      “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.

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.

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.”).

      “both parties have asserted in the Apple Litigation that the “control component” requirement is a means-plus-function limitation subject to 35 U.S.C. §112(f), despite the fact that the control component limitation does not recite “means for.” Pet. 3 (citing Ex. 1012, 3–8; Ex. 1013, 13); PO Resp. 6–7. Indeed, the court in the Apple Litigation has concluded that the control component requirement is subject to 35 U.S.C. § 112(f), and has construed that requirement accordingly: Function: receiving control signals input to the oscillating resonant module; receiving outputs from the one or more sensors; controlling oscillation of the mass to produce a vibration response according to the received control signals by generating, using one or more of the received sensor outputs, control outputs to an actuator that drives the mass to oscillate. Structure: a microcontroller, a processor, a microprocessor, or a CPU that performs the algorithm shown in Figure 45 or the algorithm described in the corresponding text. See, e.g., 31:19–32:13, and equivalents thereof. Ex. 2001, 10; Ex. 2002, 40.

      “(1) Analogous Art Our reviewing court has stated that “[t]wo separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations and internal quotes omitted). While these two criteria are helpful in many instances, we must not lose sight of the key question at hand: what is “prior art” as that term is used in 35 U.S.C. § 103(a)? References that are “too remote to be treated as ‘prior art’” are excluded from the obviousness analysis. In re Sovish, 769 F.2d 738, 741, 226 (Fed. Cir. 1985). The non-analogous art test provides helpful insight on the underlying question of what is “prior art” within the meaning of the statute; we should not, however, be blind to the reality of the circumstances of the case before us. In re Wood, 599 F.2d 1032, 1036 (CCPA (1979). Nor should we adhere to rigid and mandatory formulas that overly limit the inquiry. KSR Int’l Co., 550 U.S. at 419.” slip op. at 22

      “In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Neither party argues that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’722 patent, the background technical field, the prior art, and Petitioner’s proposed definition of the skilled artisan, which is supported with testimony of Dr. Easttom (Ex. 1003 ¶¶ 22–23), we apply the level of skill set forth above.” slip op. at 13

      “generic “reasons” to combine the alleged teachings of Lawson and Choquier lack rational underpinning, particularly for the specific and substantial modifications of Lawson necessary to reach the subject Mapping Limitation, and are beset with impermissible hindsight. The Board must “recognize that we cannot allow hindsight bias to be the thread that stitches together prior art patches into something that is the claimed invention.” Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017) (“Without any explanation as to how or why the references would be combined to arrive at the claimed invention, we are left with only hindsight bias that KSR warns against.”); see KSR, 550 U.S. at 421 (2007) (“A factfinder should be aware, of course, of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning.”). “Any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning, but so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure, such a reconstruction is proper.” In re McLaughlin, 443 F.2d 1392, 1313–14 (CCPA 1971). In this case, Petitioner does not show sufficiently how or why an alleged desire to “increase efficiency, redundancy, and scalability of Lawson’s routing network” would have led the ordinarily skilled artisan specifically to the subject Mapping Limitation, but for using claim 1 as a roadmap. Indeed, as Patent Owner persuasively argues: The Petition fails to tie these generic design goals to the specific functionality that the Petition seeks to cherry-pick from Choquier and import into Lawson. Put another way, the Petition does not explain what about Choquier’s scalability, load balancing and redundancy techniques would have motivated [the skilled artisan] to have configured Lawson’s servers to “determine which server groups (node types) should receive an event update based on this server groups to event producer mapping.” Prelim. Resp. 26–27. Petitioner never identifies how Lawson’s registries of servers/consumers become the claimed gateway-kept category→node-type mapping (EX1005, 10:63–67; 12:36–43). Nor does Petitioner show that Choquier’s service map—not keyed by message category and used for CPU-based server selection—somehow supplies the missing category→node-type routing rule that controls update-message traffic through routing nodes (EX1007, 11:2–22; 12:33–36; 12:56–61). To the contrary, Choquier’s update path increases processing by replicating each update to every server in the service group (EX1007, 21:27–50), which is the opposite of the claim’s mapping-based control that limits which nodes must process a given update. Id. at 30–31. We find this context shows that Petitioner’s reasons for combining Lawson and Choquier (and Tsutsumitake) to achieve the subject Mapping Limitation lack rational underpinning, and that Petitioner’s proposed combination of teachings is based on impermissible hindsight.” slip op. at 27
