      “During the reissue proceedings that led to the ’016 Patent, Patent Owner represented that “the ’016 patent claim limitations requiring a ‘call reception module,’ ‘presentation module,’ ‘outgoing message module,’ and ‘transmission module’ are not means-plus-function limitations and instead require only “computer program modules that are executed by processors, rather than a generic description for software or hardware.” Ex. 1003, 156– 169; see Pet. 14. For the purposes of these proceedings only, Petitioner accepts these representations and asserts that “[n]o terms require further construction and all terms can be afforded their plain and ordinary meaning.” Id. at 14–15.

      “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’s counsel during the hearing or any of Petitioner’s arguments and evidence. As confirmed by Petitioner’s counsel, Petitioner relies solely on Newstrom’s disclosure of loading its spatial database 20 into solid state memory via a “wireless connection to [a] server” in asserting that the database “may be hosted on a server that is remote from a vehicle.” Pet. 83 (citing Ex. 1012, 8:26–38; Ex. 1003 ¶ 197). Column 8, lines 27–29 is the only disclosure in Newstrom of a “wireless connection.” Although Petitioner argues that Newstrom’s system communicates wirelessly with the geospatial database while the vehicle is being driven (see Dec. 38 (citing Pet. 83); Tr. 19:20–22), Petitioner relies solely on the single instance of “wireless” in Newstrom’s disclosure to satisfy the recitation that the database (which Petitioner maps to Newstrom’s geospatial database 20) is “remote.” In the Decision, we explained that Petitioner’s reliance on Newstrom’s “wireless connection” and its assertion that the geospatial database may be hosted on a remote server were not persuasive to satisfy Petitioner’s burden to prove the unpatentability of claims 8 and 18 by a preponderance of the evidence, especially given Newstrom’s express disclosure that the geospatial database is located on the vehicle. Dec. 40–42. For example, we stated: Petitioner does not explain adequately why Newstrom’s disclosure that, when first initializing the database manager, the geospatial database is loaded into solid state memory by, for example, wirelessly transferring data from a server means that the geospatial database is remote from the vehicle. Similarly, Petitioner does not explain adequately why Newstrom’s disclosure that the database manager can load new portions of the data into solid state memory as the vehicle location changes means that the geospatial database is remote from the vehicle. Nor does Petitioner’s conclusory contention that “the geospatial database 20 may be hosted on a server that is remote from a vehicle” (Pet. 83 (emphasis added)) apprise us of disclosure that Newstrom’s geospatial database is remote from the vehicle. Dr. Morellas’ testimony is substantially identical to the Petition (see Ex. 1003 ¶197) and, thus, also fails to provide adequate support for Petitioner’s assertions. During the hearing, counsel for Petitioner confirmed that it relied solely on Newstrom’s disclose of the database using a “wireless connection” by which the database manager communicates with the database in arguing that Newstrom’s geospatial database 20 is remote from vehicle 12. Tr. 19:14–24; see also Ex. 1012, 8:27–29.

First, the parties do not necessarily disagree as to the meaning of the term “mode.” Patent Owner asserts that a person of ordinary skill in the art “would understand ‘mode’ to mean “an operational state that a system has been switched to.” PO Resp. 13. Petitioner “do[es] not necessarily object to the concept of a ‘mode’ as an operational state,” but does object to how Patent Owner applies the term. Pet. Reply 1. Petitioner objects to Patent Owner’s “application of its construction,” which, Petitioner argues, “is far narrower than the words alone suggest.” Id. Second, the intrinsic evidence, including the claims and the ’848 specification, makes it readily apparent what the ordinary and customary meaning of the term “mode” would be to one of ordinary skill in the art at the time of the invention. Based upon our consideration of the claims and the ’848 specification, we find that the term “mode,” as it is used by the ’848 patent, means a “state,” “condition,” or “operational state” of a recording device, such as a video camera, that is selected by a user and may include a selection function using threshold values.” slip op. at 19

Additional professional experience might substitute for less education and vice versa. Pet. 10–11 (citing Ex. 1011 ¶¶ 33–35).

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.

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. Resp. 33–34 (citing Ex. 2008 ¶¶ 83–84; Ex. 1001, 14:29–38).” slip op. at 12

      “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
