To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v.

Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1352 (Fed. Cir. 2010) (en banc) (“[I]t is the specification itself that must demonstrate possession.”). On the record before us, we do not agree that the ’171 Patent is entitled to a filing date earlier than Jan. 11, 2021. In particular, we do not agree that PCT ’199 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 4, 2016 filing date. The disclosures of PCT ’199 cited by Patent Owner to show written description support show: (1) transmission packets for multi-user uplink data, which includes padding such that multi-user upstream data transfers from each resource terminate at the same time (see Ex. 1012 ¶¶ 17–21); (2) performing padding on a trigger frame that triggers multi-user simultaneous transmission, where the trigger frame includes AID information of the performing preset padding before the FCS field of the trigger frame according to one embodiment (see Ex. 1012 ¶ 136, Fig. 20); and (4) inserting redundant AID information prior to the FCS field of the trigger frame, according to another embodiment (see Ex. 1012 ¶ 136, Fig. 20). PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a frame for allocating resource for uplink (UL) multi-user (MU) transmission to one or more terminals that includes the AID field set to a value related to a first padding field, when the padding field is included in the frame. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) an AID field for the MU UL resource allocation frame is set to a value, (2) that the AID field is set to a value related to the padding field, and (3) that the AID field is set to a value related to the padding field, and conditioned on the inclusion of the AID field in the frame. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20. PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment.” slip op. at 16

“At this juncture in the proceeding, and based on the current record, we do not agree with Patent Owner that “payout,” as claimed, should be limited to “the amount a player will win in relation to the amount wagered.” We recognize, as Patent Owner points out, that the examples provided in the Specification are listed in odds format. See id. at 2. The Specification, however, also states that “[a]ny suitable payouts can be used in some embodiments.” Ex. 1011, 5:18–21. This language suggests a broader interpretation of “payout” beyond just payout odds and we therefore decline to import the wager limitation into the claim term.

“Based on the evidence before us, we find persuasive Petitioner’s contention that Kido’s accumulated jackpot paid when landing on a star mark reads on the claimed “a first selected position . . . to have an increased payout . . . greater than a first non-selected payout.” See Pet. 25–27, 30, 35, 36. As explained above, the current record does not support limiting the term “payout” to just the amount a player will win in relation to the amount wagered. As Petitioner notes, a payout that receives Kido’s accumulated Prog bonus payout is necessarily higher than a payout that does not receive the Prog bonus. Pet. 35–36 (“had the first selected position not been randomly selected, the player would only be eligible for the basic payout”). Further, Kido even describes its bonus routines and jackpots as payouts. Kido describes, for example, that “[w]hen the privilege unit 113 obtains the win information from the special game value award mark win determining unit 112, it awards, as a payout, the game value stored in the accumulated game value memory 117” and it describes the “jackpot (JP) amount” as “a special payout.” Ex. 1007 ¶¶ 119, 129.” slip op. at 14

PCT ’199 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we discern no disclosure that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. Moreover, to the extent that Patent Owner’s assertions are premised on the PCT ’199’s disclosure of a preset padding being performed before the FCS field of the trigger frame and the disclosure of inserting redundant AID information prior to the FCS field of the trigger frame, we note that these disclosures are directed to two embodiments. See Ex. 1012 ¶ 136, Fig. 20. PCT ’199 does not provide any suggestion that the two embodiments are used together, or that the redundant AID information of one embodiment can serve as a preset padding of the other embodiment. On the record before us, we also do not agree that KR ’754 describes the invention in enough detail such that a person of ordinary skill in the art could conclude that the inventor was in possession of the invention as of the March 17, 2015 filing date of KR ’754. The disclosures of KR ’754 cited by Patent Owner to show written description support show: (1) multiplexed terminals over respective channels, (see Ex. 1008 ¶¶ 65–66, Fig. 10); (2) differing the number of AID values in the batch acknowledgment (BA) information field when the number of terminals assigned to each channel differs, setting the length of each multiplexed group ACK differently, and, if necessary, aligning the lengths of the multiplexed group ACKs based on the channel with the longest assigned BA information by adding zero padding or repeatedly inserting BA information (see Ex. 1008 ¶¶ 66–70, Fig. 11); and (3) applying the use of the AID field padding and the use of BA padding in a downlink OFDMA trigger process during multi-user downlink transmission to align the length of the trigger when the AP notifies the terminals assigned to each channel by inserting zero padding or repeating AIDs (see Ex. 1008 ¶¶ 71–72, Figs. 11–12). KR ’754 does not describe the invention in enough detail to enable a person of ordinary skill in the art to conclude that the inventor possessed a trigger frame indicating uplink transmission for one or more terminals that includes an AID field used to identify whether the trigger frame includes a padding field, and the trigger frame including the padding field when the AID field is set to a specific value. In particular, we do not discern disclosure in KR ’754 that conveys that the inventor possessed the following: (1) a trigger frame indicating uplink transmission to one or more terminals and including an AID field used to identify whether the trigger frame includes a padding field; (2) the AID field for the trigger frame is set to a specific value, and (3) that trigger frame includes the padding field when the AID field is set to a specific value. We find misplaced Patent Owner’s argument that “KR ’754’s discussion about Figure 10 and Figure 11 would have been understood [by a POSITA] as disclosing a padding method used to improve predictability and consistency trigger frame” (Prelim. Resp. 12) because: (1) it addresses uplink transmissions and not a trigger frame indicating uplink transmission to one or more terminals; (2) it does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) it is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. Argument of counsel cannot take the place of objective evidence. See Gemtron Corp. v. Saint-Gobain Corp., 572 F.3d 1371, 1380 (Fed. Cir. 2009). We also find misplaced Patent Owner’s argument that “the padding discussed by KR ’754 regarding its Figure 12 embodiment is not limited to downlink transmission and would have been understood by a POSITA as also being used to schedule uplink ones” (Prelim Resp. 14) because: (1) KR ’754 does not provide any suggestion that the same technique can be used for uplink transmission trigger frames; (2) Patent Owner’s argument does not address that the padding field is included in the trigger frame when the AID field is set to a specific value; and (3) Patent Owner’s argument is unsupported attorney argument regarding the understanding of a person of ordinary skill in the art. See Gemtron, 572 F.3d at 1380. For the foregoing reasons and based on this record, for the purpose of institution, we find that the ’186 Patent is not entitled to an effective filing date earlier than April 8, 2019 and find that Kim is prior art. We note that the limitations at the heart of the written description dispute were added in an amendment filed August 9, 2020. See Ex. 1002, 214–21.

“We do not agree with Patent Owner’s arguments because they are premised on Choi’s teachings as limited to AIDs transmitted via a control frame broadcast as a TIM element.

Chu, Choi, and the testimony of Dr. Ding (Ex. 1003), we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to combine Chu’s teachings with Choi’s use of specific AID or ΔAID values as indicators of the end of meaningful data and the beginning of padding that would allow client stations to reliably determine where the useful content of the trigger frame ends and where optional padding begins, with the benefits of improved parsing efficiency, enhanced synchronization, and reduced likelihood of misinterpreting padding as data as padding.

Patent Owner next contends that Kido does not disclose a first payout that is “for the spin of the roulette wheel.” Prelim. Resp. 29. Patent Owner’s argument is premised on the cumulative nature of Kido’s Prog bonus – it builds with every spin of the roulette wheel until won. Id. (“Each time the wheel is spun, 0.5% of the amount wagered is added to the progressive jackpot, and thus, the jackpot’s value reflects multiple spins of the roulette wheel.”). Thus, according to Patent Owner, the value of the jackpot is determined using multiple spins of the roulette wheel and is not “for a spin of the roulette wheel” as claimed.” Id. at 30. The claims, however, only require a first payout that is higher than a second payout. Nothing prohibits the higher payout from accumulating from prior spins of the roulette wheel because, when it is actually won, it will be for that last spin of the roulette wheel. Ex. 1005, 8:35–36 (“indicating that the first player is to be paid at the first payout for the spin of the roulette wheel”). Regardless of how Kido’s Prog bonus accumulated, it is paid for a spin of the roulette wheel – at that juncture Kido discloses each claim element. Anticipation occurs when a prior art reference discloses every element of a patent claim at a point in time, as Kido does with a single spin of the roulette wheel that pays the Prog bonus. As persuasively explained by Petitioner, “the steps of Figure 12 (including A13) occur within a single round of roulette, for a single spin of the roulette wheel, until the routine ‘returns to the step of A1 and is transited to a next game.’” Pet. 39 (quoting Ex. 1007 ¶ 233).” slip op. at 13

“The ’655 patent Specification states that: The topology data table 21 of the online server 20 is mainly recorded with a link data 49 between each of the P2P devices 41– 46 within the P2P device community. The link data 49 refers to the connection relationship between the P2P devices 41–46, which includes, but is not limited to, the connection structure, connection data and/or locations of connection. Ex. 1001, 4:51–57. On this preliminary record, we agree with Petitioner that the term “link data” is a “connection relationship between the P2P devices.” This meaning is consistent with the ordinary meaning of the term within the context of the claim, that is, “link data” means data on the links (connections) between each of the P2P devices, where the Specification provides a more fulsome meaning that the term includes, at least, “the connection structure, connection data and/or locations of connection.” See id. at 4:55–57.

“Lee discloses that the P2P overlay is generated with the overlay generation unit 220 that generates the P2P overlay by analyzing information regarding “the corresponding application service, the peer, and the network,” where the network information “may include a network topology, a maximum bandwidth, a current network usage, [and] a transmission delay time, and the like.” Ex. 1005 ¶ 54. We determine that this disclosure provides support for Mr. Lett’s testimony that “Lee describes techniques for changing an overlay in response to changing network characteristics,” which could be beneficial. Ex. 1003 ¶ 48. Accordingly, on this preliminary record, we find this evidence is sufficient to support a rationale to combine Schwan and Lee.

“To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. Osseo Imaging, LLC v.

“C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v.

“Additionally, we credit the testimony of Dr. Almeroth, who opines that Kleve discloses that certain restrictions are sent with the request to generate a virtual key. Ex. 1003 ¶¶ 118–123. Specifically, Dr. Almeroth testifies that Kleve discloses that the virtual key “enable[s] the keyless drive system for the appropriate Temporary User during a given rental period.” Id. According to Dr. Almeroth, this “indicates that rental agreement restrictions were sent with the request so that the virtual key could be associated with said restrictions.” Id. (citing Ex. 1004 ¶¶ 39, 68 (“Once the rental period has expired the virtual key may be reset and cleared from the VCS.”)). Dr. Almeroth further testifies that the virtual key in Kleve is always generated after the rental agreement. Id. (citing Ex. 1004 ¶¶ 39 (“[O]nce the Temporary User selects the vehicle, pays the appropriate amount and signs a consent agreement, th[e]n the system may generate a virtual key to distribute to the Temporary User and VCS.”), 68). We do not agree with Patent Owner’s argument that Dr. Almeroth’s declaration testimony contradicts Kleve. See PO Resp. 27–29. Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing Ex. 2030, 27:5–10, 27:21–28:1). In a particular embodiment to which Dr. Almeroth was citing, he noted that the e-key is always generated after the rental agreement. See Ex. 2030, 26:14–20. Then the following exchange occurs: Q. So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don't know that the real world is necessarily cut and dry. So reading -- a person reading Kleve would understand it’s describing embodiments where it’s always the case. That might be a pretty common scenario, but I don't know that it would necessarily be a hard and fast rule in every embodiment or in the understanding a person of skill in the art would have. Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2001 ¶¶ 56–57. Therefore, we do not credit or agree with Dr. Malek’s testimony that Kleve teaches away from the concept of a virtual key created with the agreed-upon rental period as a restriction.

“On the current record, we determine that the “modified embedded resource” may be a “link.” Both Petitioner and Patent Owner point to claim 13, which explicitly states that a modified embedded resource is a link. Because claim 13 depends from claim 1, claim 1 must be broad enough to encompass a modified embedded resource that is a link. Patent Owner also points to a statement in the ’322 patent that “[t]he embedded resource is a link.” Prelim. Resp. 18 (citing Ex. 1001, 4:26–31). Patent Owner argues that every embodiment of the ’322 patent “involves embedding the ‘modified embedded resource’ in another resource when it is returned to the client.” Paper 16, 2–3. Patent Owner cites to description in the ’322 patent of a “document” or a “page” returned to the requesting client. Id. (citing Ex. 1001, 4:42–48, 7:48–55). However, claim 15 does not return the modified embedded resource to the client, only the origin system. Claim 1 recites only that the “modified embedded resource” is returned to the client device with the content resource. Neither claim 1 nor claim 15 recite returning a document or a page containing the modified embedded resource, only the modified embedded resource itself. We acknowledge some tension with the adjective “embedded,” which Patent Owner argues requires that the embedded resource be embedded in something. Paper 16, 1–3.

Kenner describes that content coordinate data is maintained on a database of each IM, which includes the Internet address of all other connected IMs and content coordinate data describing the type of files stored by the SRUs of each IM. Ex. 1005, 41:1–6. That content coordinate data, stored in each video ID and each IM, teaches the claimed association of alias with repeater server.
