“Pursuant to 35 U.S.C. § 324(a), the Director may not authorize a post-grant review unless the information in the petition, if unrebutted, “would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” See 37 C.F.R. § 42.4(a) (“The Board institutes the trial on behalf of the Director.”). For the reasons that follow, we institute a post-grant review as to claims 1–20 of the ’423 patent on all grounds of unpatentability asserted in the Petition.” slip op. at 2

Patent Owner does not address the level of ordinary skill in the art in its Preliminary Response. Based on the record presented, including our review of the ’423 patent and the types of problems and solutions described in the ’423 patent and cited 2 Petitioner states that it “takes no position on the proper priority date for the [c]hallenged [c]laims” and “uses the earliest possible priority date claimed, December 18, 2013,” for purposes of its asserted grounds.

“B. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.200(b). Petitioner states that, “for purposes of [its] Petition, the Board need not construe any claim terms to resolve the parties’ disputes, and the claims should be given their ordinary and customary meaning.” Pet. 20. Patent Owner agrees that “[n]o constructions are necessary” to decide the issues disputed by the parties. Prelim. Resp. 2–3. We conclude that no express interpretation of any claim term is necessary to determine whether to institute a post-grant review in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted) (emphasis added)).” slip op. at 8

“For the reasons explained below, we conclude, on the merits and based on the current record, that Petitioner has shown that it is more likely than not that claim 1 is unpatentable as claiming patent-ineligible subject matter under 35 U.S.C. § 101. See Pet. 77–84. Accordingly, we need not determine at this time whether collateral estoppel applies based on the Board’s decision in PGR2021-00093. The parties, however, should address the issue in their papers during trial, with citations to relevant authority. In particular, the parties are encouraged to address (1) how the collateral estoppel requirement that the issue be “identical to one decided in the first action” applies in the context of an asserted ground under 35 U.S.C. § 101, and (2) the parties’ apparent disagreement as to whether collateral estoppel may be applied in such circumstances on a “limitation-by-limitation basis.” See Pet. 72, 75 (quoting Google LLC v. Hammond Dev. Int’l, Inc., 54 F.4th 1377, 1381 (Fed. Cir. 2022)); Prelim. Resp. 20–21; see also Kroy IP Holdings, LLC v. Groupon, Inc., – F.4th –, No. 2023-1359, 2025 WL 2178321, at *4 (Fed. Cir. Aug. 1, 2025) (Dyk, J., dissenting) (“In subsequent Board proceedings, it is well established that collateral estoppel applies to claims adjudicated by the Board to be unpatentable and also to ‘related claims that present identical issues of patentability,’ i.e., patentably indistinct claims. . . . ‘It is well established that patent claims need not be identical for collateral estoppel to apply.’” (citing MaxLinear, Inc. v.

“The district court considered the issue of whether a client device, for instance, should be construed in a role-based or structural manner, and the evaluation included whether a device could sometimes be operated as a client and at other times could operate as something else. Ex. 1018, 48–51. In support, the district pointed the patent disclosure that: Any network element in the system may be a dedicated device that assumes only a single role, and thus being only a client (using tunnels), a tunnel, a client (using agents/ peers), an agent, or a peer device. Alternatively or in addition, a network element may be capable of assuming two or more roles, either at different times or simultaneously, from the list of roles including a client (using tunnels), a tunnel, a client (using agents/peers), an agent, or a peer device. Alternatively or in addition, a device may be capable of assuming all of the above roles. Ex. 1018, 50 (quoting ’866 patent at 125:33–42, with identical disclosure in ’034 patent (Ex. 1001, 125:24–33)).” slip op. at 10
- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted
“At this stage of the proceedings, we do not agree that Mithyantha’s second appliance 200’/200b cannot be considered the claimed “second client device” and its first appliance 200/200a cannot be considered the claimed “third server.” As discussed supra Section II.C, we have adopted the district court’s constructions of claim terms. More specifically, the district court determined, and we concur based on the present record, that “client device” is “a device that is operating in the role of a client by requesting services, functionalities, or resources from other devices” and a “first server” functions as “a server that is not the client device.” On this record, Petitioner has demonstrated that Mithyantha’s second appliance 200’/200b functions as the claimed “second client device,” as it operates as a client by requesting services, functionalities, or resources from other devices, that is, it transmits HTTP web requests over the network to a server. See Pet. 44– 45. Mithyantha also discloses that its first appliance 200/200a functions in a server role, with appliance 200/200a sending back responses to client 102a, that is, content from the web server, and it is a separate element from a client device. See id. at 41–42. Moreover, as discussed above, Petitioner’s assertions are consistent with the role-based nature of the elements as disclosed in the ’034 patent. Further, we do not find that Petitioner’s applications of the claim elements to Mithyantha are arbitrary because they are consistent with the district court’s claim construction of the respective claimed elements and the elements’ functions and roles, as discussed. Moreover, Mithyantha discloses that its appliances can provide different functions (see e.g. Ex. 1009, 5:31–33, 8:65–67, 9:8–21, 9:53–55; 23:58–64), and may be implemented in many forms. That is, the implementation of appliance 200 is generally described as being on any form of computing device such as “computing device 100,” and “computing device 100 can be any workstation, desktop computer, laptop or notebook computer, server, handheld computer, mobile telephone.” See id. at 13:65– 142, 16:58–64. We do not agree with Patent Owner’s allegations regarding a required architecture. Patent Owner does not explain how these requirements are recited in the limitations of claims. Instead, at this juncture, it appears that the arguments are an attempt to impermissibly introduce limitations into the claim that are not recited. Similarly, we do not agree with Patent Owner’s arguments on required anonymity because this requirement is not recited in the claims.” slip op. at 18

We discern no reason, at this stage of the proceeding, to question Petitioner’s proposed level of ordinary skill, which is supported by the prior art. See Okajima v.

“Section 42.6(a)(3) states that “[a]rguments must not be incorporated by reference from one document into another document.” The purpose of this rule to prevent a party from circumventing page limits and to conserve Board resources. See Cisco, 10 (“incorporation by reference of numerous arguments from Dr. Roy’s 250-page Declaration into the Petition serves to circumvent the page limits imposed on petitions for inter partes review, while imposing on our time by asking us to sift through over 250 pages of Dr. Roy’s Declaration . . . to locate the specific arguments corresponding to the numerous paragraphs cited to support Petitioner’s assertions.”). Patent Owner does not identify specific arguments in Mr. Plunkett’s declaration that are not in the Petition, or specific conclusory statements within the Petition that are overly reliant on the Plunkett Declaration. Nor have we found any improper incorporation in the course of our own review. Accordingly, we are not persuaded that we should ignore any portion of the Plunkett Declaration on this basis.” slip op. at 28
- Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) does not applyDecided for petitioner
“Claim terms using the word “means” are presumed to invoke § 112(f), and terms without the word “means” are presumed not to invoke this subsection. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015). Because “server gateway” does not include the word “means,” it is presumed not to be a means-plus-function claim term under § 112(f). This presumption can be rebutted, however, by demonstrating that the term fails to “recite sufficiently definite structure,” or recites “function without reciting sufficient structure for performing that function.” Id. at 1349 (internal quotation marks omitted). It is Patent Owner’s burden to produce sufficient evidence to overcome this presumption. See Dyfan, LLC v. Target Corp., 28 F.4th 1360, 1367 (Fed. Cir. 2022) (“From a procedural standpoint, this presumption imposes on the party challenging the presumption the burden of going forward with evidence . . . that a person of ordinary skill in the art believes the term does not recite sufficiently definite structure.”) (internal citation, quotation marks, and alterations omitted). There does not appear to be a dispute, at this stage of the proceeding, that “server gateway” denotes at least some structure to persons of ordinary skill: a server connecting a game user computational device and a blockchain. Thus, we are not persuaded, on the current record, that “server gateway” is a “generic term[] or black box recitation[] of structure or abstractions.” MTD Prods. v. Iancu, 933 F.3d 1336, 1341 (Fed. Cir. 2019). Patent Owner nonetheless argues that although the term may recite some structure, the recited structure is insufficient to perform “the recited functions,” which Patent Owner asserts are: (1) “operating a blockchain” slip op. at 14
