“construction of “feature flag” is inconsistent with the language of claim 8, which states that “the feature flag indicates that the running state of the second apparatus is the sleep state.” Petitioner also argues that Patent Owner’s proposal is not supported by claim 24, which depends from claim 23 and states that “the feature flag is located at a header of the sleep login packet.” Id. at 3. We agree with Petitioner. The plain language of claim 8 states what a feature flag indicates. Claim 24 recites where the feature flag is located.

“[A] prior art reference will anticipate if it ‘disclose[s] each and every element of the claimed invention . . . arranged or combined in the same way as in the claim.’” Blue Calypso, LLC v.

“B. Level of Ordinary Skill in the Art Petitioner, relying on the testimony of Dr. Zagal, argues that a person having ordinary skill in the art “would have had an undergraduate degree in game design or development, computer science, computer engineering, or a related field, with at least two years of experience working with computer gaming systems or software application development.” Pet. 2 (citing Ex. 1003 ¶¶ 62–66). Petitioner also contends that “[l]ess work experience may be compensated by a higher level of education or vice versa.” Pet. 2–3 (citing Ex. 1003 ¶¶ 62–66). Patent Owner, relying on the testimony of Dr. Akl, contends that a skilled artisan “would have a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with one to two years of experience developing or programming video games or video game systems, or similar types of computer systems,” but notes that a skilled artisan “may have additional education that might substitute for some of the experience, and additional substantial experience might substitute for some of the educational background.” PO Resp. 2–3 (citing Ex. 2004 ¶ 28). According to Patent Owner, Petitioner’s proposal does not require Owner states, “[t]his difference does not materially affect the analysis presented below.” PO Resp. 3. We see very little difference between the parties’ respective proposals. We adopt Patent Owner’s more specific proposal because it is consistent with the level of skill evidenced in the ’958 patent and the applied prior art, but we agree with Patent Owner that this does not affect our analysis; we would reach the same conclusions under Petitioner’s proposal.” slip op. at 5

“requirements for the language “for use in a video game,” including that the updated video-game content be an interactive object that is inserted into an existing game, or at least a new ad unit not already present in the game, and that the updated content alter the function of the game. PO Resp. 15–17. Patent Owner offers no persuasive support for these restrictions on the claim language. The claim language itself suggests no such restrictions. Rather, the claim language simply recites video-game content that is for use in the video game. The claim language does not specify who or what must use the content or how it must be used. Thus, the claim language itself is broad and includes none of the restrictions Patent Owner would place on it.” slip op. at 8

“Owner’s position to be that mere storage of content is not enough to show pre-selection of that content. For example, during oral argument, Patent Owner’s counsel argued as follows: I don’t think it’s just as simple as saying, well, anytime you store anything, it’s been pre-selected, because again, that kind of reads out pre-selection, as well. And the same thing with indexing. I think that’s simply too broad. There must be some pre-selection of, you know, kind of narrowed down content, if you will, but then when the request comes in, you choose among that pre-selected content for the final selection. Tr. 31:18–23; see also PO Resp. 11 (“[E]xtending the claim to content that is merely selected from storage and sent gives no meaning to pre-selected . . . .”), 12 (“[C]ontent is not shown to be pre-selected by selecting it from storage and sending.”); Tr. 31:2–5 (Patent Owner’s counsel’s argument that “there must be a pre-selection of certain content that will be available from which to select once the request is received, and then the checking step is performed in the various claims here”), 34:23–24 (Patent Owner’s counsel’s argument that “[t]here still must be a pre-selection, which we don’t think is simply, you know, the act of storing”). As explained below in Sections II.D.2.b and II.D.6, Petitioner’s contentions based on Hays show that Hays teaches pre-selected ads, as recited in claims 1 and 8, and a pre-selected message, as recited in claims 5 and 12, according to Patent Owner’s understanding of the term. Therefore, we apply Patent Owner’s interpretation in our patentability analysis, and we need not provide a full claim interpretation, nor do we need to resolve whether pre-selecting can be met by merely storing data.

“unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b). Patent Owner argues that “Hays is only a ‘printed publication’ under § 311(b) as of the date it became available to the public—i.e., after the June 26, 2007, priority date of the ’958 Patent,” and, therefore, that Hays is “ineligible to be prior art in an IPR.” PO Resp. 48–50. The Federal Circuit has rejected this argument, holding that a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date. Lynk Labs, Inc. v. Samsung Elecs. Co., 125 F.4th 1120, 1127 (Fed. Cir. 2025). Thus, Petitioner asserts a permissible ground of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–14 are unpatentable under 35 U.S.C. § 103(a) on the basis of Hays, which is a prior art printed publication.” slip op. at 15

Resp. 14– 15.8 However, for reasons similar to those discussed in the final written decision in IPR2022-01086, Paper 37 at 15–19, we determine that the “content-related” data segments do not support Patent Owner’s proposal, 7 The ellipses represents omission of the phrase “within the respective data file” because, as discussed above, we need not decide if the preamble (which introduces the data files) is limiting with respect to requiring data files. As discussed below, Petitioner’s showing includes relying on separate data files in Comps. 8 We also recognize that whether two segments have “syntactical meaning” between them may be somewhat subjective as discussed in the analysis of Petitioner’s challenges below. namely “data segments ordered in a file such that they will present the file’s contents in their intended presentation order when rendered sequentially.” See Prelim. Resp. 14; IPR2022-01086, Paper 37 at 15–18. Contrary to Patent Owner’s arguments, the “syntactical meaning” as disclosed in the specification does not require “a sequential, chronological nature” specified by the content relationship, because claims 1 and 9 separately recite that feature by requiring “outputting . . . the content-related first data segments and the content-related second data segments according to their chronological sequence.” See Prelim. Resp. 17 (agreeing that “[i]ndependent claims 1 and 9 require outputting the data segments “sequentially” and “according to their chronological sequence.”).

“VII. ANALYSIS A. Legal Standards “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)); see also 37 C.F.R. § 42.104(b) (2019) (requiring a petition for inter partes review to identify how the challenged claim is to be construed and where each element of the claim is found in the prior art patents or printed publications relied upon). A claim is unpatentable under 35 U.S.C. § 103(a) if “the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) when in evidence, objective evidence of obviousness or nonobviousness, i.e., secondary considerations.5 See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). An obviousness analysis “need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.” KSR, 550 U.S. at 418. Additionally, the obviousness inquiry typically requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2016) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Furthermore, Petitioner does not satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed.

“To resolve this controversy, we turn to the decision in Hulu, LLC, v. Sound View Innovations, LLC, IPR2018-01039, Paper 29 (PTAB Dec. 20, 2019). In Hulu, the Board issued a decision denying institution of an inter parties review because the Board found that a petitioner failed to sufficiently show that a reference qualified as a printed publication. Id. at 2. The Board’s Precedential Opinion Panel (POP) ordered a review on rehearing to address the issue of what is required for a petitioner to establish that an asserted reference qualifies as a “printed publication” at the institution stage. Id. The POP determined that the statutory “reasonable likelihood” standard for institution applies to the issue of whether a reference is a printed publication. Id. at 13. The POP “explained that it is a higher standard than mere notice pleading, but, . . . it is lower than the ‘preponderance’ standard to prevail in a final written decision.” Id. In Hulu, Patent Owner argued that “the reasonable likelihood standard is satisfied only when a petitioner presents its ‘case in chief’ in the petition, including all evidence that will be used in any instituted review, with a few limited exceptions.” Id. at 11. The POP, however, determined that “[w]hile the petitioner must submit evidence sufficient to meet the reasonable likelihood standard, some limited opportunities exist for the petitioner to present new evidence later, including: (1) in a reply to a patent owner preliminary response; (2) in a reply to the patent owner response; and (3) in a motion to file supplemental information.” Id. at 14. The POP explained that, for example, “if the patent owner challenges a reference’s status as a printed publication, a petitioner may submit a supporting declaration with its reply to further support its argument that a reference qualifies as a printed publication.” Id. at 15. The POP also explained that, if a patent owner does not challenge the reference’s status as a printed publication, the petitioner may move to submit the declaration through the supplemental information process.

“Patent Owner contends that Basturk teaches away from providing authentication as an application protocol on an application layer because Basturk discloses that the presence of application level security features does not necessarily imply the security of delivery, which shows the need for security at the transport layer. Prelim. Resp. 43–53. However, Basturk discloses that application level security features are provided by application level security. Ex. 1006, 3. For example, Basturk discloses guaranteeing integrity by signing the data before passing it to the transport level. Id. at 3– 4. Basturk further discloses “a method to transform any transport protocol into a ‘secure’ version, equipped not only with the new security features discussed above, but providing, at least as options, the standard application level security features.” Id. at 5. At this stage, we are sufficiently persuaded that Basturk teaches providing standard application level security features such as authentication. Patent Owner contends that on-the-fly processing as taught by Basturk is not enabled by the use of a trailer. Prelim. Resp. 52–55. Basturk discloses computing signatures as data transmission proceeds, to achieve the goals of avoiding slowing down the regular flow of data, and allowing the possible off-load of signature computations. Ex. 1006, 7, 12. Basturk discloses that the signature of an outgoing packet is computed after data encryption, which complies with the requirement that the signature is computed “on-the-fly.” Id. at 14. Dr. Houh testifies that computing the signature “on-the-fly,” as data is being transmitted, provides the benefits of faster data transmission, reduced jitter, and reductions in computing power. Ex. 1003 ¶ 64. Dr. Houh testifies that calculating the signature of Handley’s RTP packet “on-the-fly” and placing the signature at the end of the packet as taught by Basturk yields the benefit of transmitting data while computing the signature, which minimizes latency as taught by Basturk. Id. ¶ 85. At this stage, we are sufficiently persuaded that a person of ordinary skill would have placed the authentication information of Handley’s RTP packet at the end of the packet as taught by Basturk to yield the benefits of faster data transmission, reduced jitter, and reductions in computing power. Accordingly, for purposes of this Decision, we are persuaded that Petitioner cites sufficient evidence to support its contention that a person of ordinary skill would have had reason to combine the teachings of Handley and Basturk.” slip op. at 20

“Dr. Houh further testifies that, given the remaining choices of placing the authentication data at the beginning or the end of the payload data, a person of ordinary skill would have recognized that placing the authentication data at the end of the payload data would reduce latency because this allows the packet to be transmitted while the authentication data is calculated. Ex. 1003 ¶ 178. To support this testimony, Dr. Houh relies on other protocols that use integrity checks, such as the Frame Check Sequence located at the end of an Ethernet Frame. Id. (citing Ex. 1014). We are sufficiently persuaded at this stage, based on Dr. Houh’s testimony and supporting evidence, that a person of ordinary skill would have placed the authentication data at the end of the whole RTP packet payload as claimed. Further, on this record, given the choice between placing authentication data at the beginning, middle, or end of the packet, we are sufficiently persuaded that it would have been obvious to place the authentication data at the end. See KSR, 550 U.S. at 421 (“When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp.

“we consider whether that construction was intended to encompass varying durations during the creating step or the displaying step. In its opinion, the Microsoft court observed that the defendants in that case argued that “before created,” and that “the ‘duration information’ is a parameter that the user can then interact with in order to vary the display of each resource.” Ex. 1014, 22. Patent Owner, the court continued, argued that “all that is required is for the user to maintain control over the actual presentation of the resource during the ‘displaying’ step, and that no duration information need be provided during the ‘creating a show structure of nodes’ step.” Id. at 22–23. The Microsoft court “agree[d] with [Patent Owner] that the user should be able to vary the duration of the content during show structure playback. This is the ‘interactive’ component of the claim.” Id. at 23; see also Prelim. Resp. 29 (arguing that this reasoning supports Patent Owner’s position that “the claim language expressly requires that the end user be able to ‘vary said duration’ for how long resource content currently ‘is being displayed’ to the user in ‘accordance with said show structure’ to which the resource belongs”). Here, the Microsoft court expressly states that the duration is varied during show structure playback, which is a clear reference to claim 1’s step of “displaying a content corresponding to each of said resources automatically in accordance with said show structure.” The Microsoft court “also finds that some duration information must be provided when the show structure of nodes is created,” that “‘parameter’ is a helpful concept for construction,” and that “the ‘duration information’ may be understood to be synonymous with a ‘parameter,’ as that timing information is the variable that will specify how long a particular content will be displayed.” Ex. 1014, 23.

“As noted above, the Microsoft court construed “interactively variable duration information” to mean “a parameter specifying how long a content is to be displayed by default before a subsequent content is displayed, where the viewer of the content can change the parameter.” Ex. 1014, 22. The construction itself suggests that the duration information is varied during display, because it is in the context of resources being displayed sequentially and “the viewer of the content can change the parameter.” As to Escobar, Petitioner contends that “[w]hen playing decision lists/timelines in the authoring tool using Button 174 (invoking subroutine E), the user is the viewer of the content.” Pet. 49 (citing Ex. 1004, 6:40–45). Thus, Petitioner appears to contend that, during the process of creating a show structure, the creator is a viewer if the creator can view the edited content corresponding to a node as the show structure is being created. Here, Petitioner would satisfy the “viewer” aspect of the Microsoft court’s construction by pointing to a creator viewing a piece of the show structure during the creating step, although Escobar does not teach that the creator can vary the duration of content while viewing it or that durations can be varied while a show structure (as opposed to a node being created) is being displayed in the displaying step, as discussed in more detail below.” slip op. at 13

“We agree with Patent Owner and find Petitioner’s arguments unpersuasive. In particular, we find Petitioner does not show sufficiently, let alone with particularity, how or why 802.11ac allegedly discloses (explicitly or inherently) the combined features of “determining” that the number of elements in the set of STA Info fields “is one,” and “in response to” that determination, transmitting first CSI feedback in response to receiving the NDP. Instead, as noted by Patent Owner (Prelim. Resp. 32), Petitioner merely contends that, because 802.11ac’s VHT SU beamforming can be performed with a single station, 802.11ac allegedly discloses sending feedback in response to determining that the number of the one or more STA Info fields in the NDPA is one. We find Petitioner’s reasoning here unpersuasive, and agree with Patent Owner and its expert that Petitioner does not explain, sufficiently and with particularity, how any disclosure in 802.11ac describes channel sounding feedback being sent or received in response to determining the number of STA Info fields. See Prelim. Resp. 31–33; Ex. 2003 ¶¶ 104–109; see also Prelim. Resp. 28–31.
