“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. For the purposes of its Preliminary Response, Patent Owner agrees with Petitioner. Prelim. Resp. 5. After reviewing the parties’ arguments and evidence, we determine that no express constructions of any terms are needed for us to render our Decision on Institution. See, e.g., Nidec Motor Corp. v.

“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. 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). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary 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

“and quotes various passages in Chow. Pet. 13–14. For example, Petitioner identifies that, under “Description of the Related Art,” Chow states: “Typically, workload is apportioned by somehow logically dividing the data to be processed. For example, a block of data might be divided evenly into a number of parts equal to the number of available threads, so that each thread can independently process a separate portion of the data. This is called ‘static’ or ‘a priori’ partitioning.” Pet. 13 (citing Ex. 1003, 1:38–42; Ex. 1022 ¶ 144). Petitioner also identifies that Chow describes “aggregate tasks” divisible into “multiple sub-tasks,” and “multiple task execution units are independently operated on-demand to sequentially self-allocate and execute sub-tasks of the aggregate task.” Pet. 13–14 (citing Ex. 1003, 1:66–2:15). After presenting such quoted passages from Chow, Petitioner proffers the conclusion that Chow discloses the Partitioning Limitation, but does so without sufficiently explaining why such passages allegedly teach or suggest the features of the Partitioning Limitation not only within the context of claim 1 as a whole, but given that Chow itself disparages such “static” or “a priori” partitioning as posing “a significant problem” (Ex. 1003, 1:52–58).

Whereas claim 1 (the method claim) recites a series of steps, each performed “by a processor,” claim 10 (the system claim) recites a “processor” with stored instructions that perform the same steps recited in claim 1.

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

Patent Owner argues that Petitioner has not shown that this limitation disclosed or rendered obvious by the relied-on references. See Prelim. Resp. 29.

Petitioner further contends that “[a] POSITA would have also recognized that the initial position setting provides a location reference for gameplay.” Id. at 63. For this Ground 2, Patent Owner incorporates by reference its arguments regarding Ground 1 based on Cheok, Nakamura, and Foxlin077. See Prelim. Resp. 29. Patent Owner argues that “Nakamura’s position icon 113 [displayed at a virtual location appropriate for the initial position] represents a virtual character’s virtual location in the virtual world, rather than a user’s physical location, and has no relationship to the physical location.” Prelim.

“We are not persuaded by Patent Owner’s arguments. As stated in our summary of Petitioner’s contentions, Petitioner relies on what would have been obvious to a person of ordinary skill in the art given Levine’s programming architecture and providing a button or other interface for the avatar to perform an action in that game. It seems reasonable, at this juncture, that Levine’s teachings of various actions that characters of a game can take (picking up a sword, for example), combined with the teaching that a user can press *9999 to “kill” a monster, reasonably support that a person of ordinary skill in the art would use Levine’s teachings of a client interacting with a game object (by clicking a mouse, angling the joystick or pressing a trigger button) to provide a button to “shoot” the sniper’s rifle as argued by Petitioner. Ex. 1003 ¶¶ 211, 528, 659. Furthermore, we are not persuaded by Patent Owner’s characterization of Levine as having no need for manual control of the “sniper” rifle. None of the passages of Levine that Patent Owner points to state that the actions by an avatar are automated. And even if some automation of actions were implemented in a game, Levine leaves it to the game designer to implement the set of rules on how the user’s actions would affect the state of the objects in the game. See id. ¶ 351. Accordingly, given the latitude of design options that Levine describes to interact with an avatar, Petitioner’s contention of using Levine’s interface space with buttons appears to be a reasonable and suitable option for playing Levine’s “sniper” game, and require the manual interaction with such a button to “shoot” the rifle.” slip op. at 23

“We are persuaded by Petitioner’s showing at this juncture, that Levine teaches the “location-based game” by describing the use of Locales in the grid system to show the “virtual playfield” in which the games are played, and that the “first character” in Levine is an “avatar” controlled by a user as described by Petitioner and summarized above. We are also persuaded by Petitioner’s showing at this juncture (and as summarized above) that Levine teaches a “first character in said virtual playfield is displayed on a display” because in the example described as the “sniper” game, Levine renders a graphical representation (depicted in Figure 47) of the Locale in which the “sniper” is located and the relative position of other game characters in nearby areas. In addition, it is reasonable to conclude, based on the argument and evidence in the present record, that it would have been obvious to show the required location in the “monster” game given that the users roam around Wall Street with the objective of finding “monsters” to “kill” and as such, it would have been obvious to display, on whichever device users are using to play, the location of the “avatar” and the “monsters.” And currently there is no evidence in the record showing that displaying locations of the “avatars,” “monsters,” or any other character’s locations would have been uniquely challenging or difficult for one of ordinary skill in the art.
