In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26.

    “Hays discloses that an advertiser can target particular ads at particular times, such as “air[ing] the Domino’s ad campaign” after a “game has been played for 45 minutes.” Ex. 1005 ¶ 22. Thus, an advertiser selects ads to run, and those ads become part of the pool from which the advertising matching and weighting system selects ads. See Ex. 1005 ¶ 22 (“Based on information associated with each of the available ad units (e.g., current game environment, game title genre, predicted player demographic information for current available ad unit, player geography, time of day, etc.), the advertisement server may then (through matching and optimization) distribute and deliver targeted advertisements to players’ gaming devices, where the advertisements may be integrated into the relevant game areas in real time.” (emphasis added)). Thus, we agree with Petitioner that the ad targeting described in Hays’s paragraph 22 happens before the matching and weighting system determines which ads to serve. Pet. Reply 3–4 (referring to Hays’s paragraph 22 and arguing that the “pre-selection plainly happens serve to a particular mobile device”). In other words, ads are pre-selected before they are ultimately selected by the matching and weighting system. Petitioner’s contentions and Hays’s disclosures are consistent with the ’056 patent’s written description, which states the following: The pre-selected content may be stored on a storage medium accessible by the server. Updated content may be chosen from pre-selected content based on at least one of the factors including a type of the mobile communication device, a telecommunication service, a subscription associated with the mobile communication device, and a service provider of the telecommunication service. Ex. 1001, 11:34–40. Thus, the ’056 patent discloses that content is selected from pre-selected content. Claim 9 similarly requires identifying “what preselected in-game video game content to send,” meaning that content is selected from pre-selected content. See 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”), 31:21–23 (Patent Owner’s counsel’s argument that “[t]here 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”). On this record, we find that Petitioner’s contentions and Hays’s disclosure of selecting ads to serve from a pool of ads that are selected ahead of time are consistent with the written description of the ’056 patent and show how Hays teaches the pertinent claim limitations.” slip op. at 22

In this example, “several items 210, 220, 225, 230, and 235 are shown within scene 200,” and virtually any of these items may be changed by receiving updated content on the mobile communication device. For instance, the shirt 230 might be updated to include a logo associated with third party X (as shown). The poster 225 might advertise an upcoming movie for third party Y, and chalk board 220 may contain a handwritten advertisement for third party Z (as shown). Ex. 1001, 6:42–50. When an advertising contract changes, “the mobile communication device may thereafter download updated content reflecting a new graphic, shirt, or entirely new object, to place at 230.” Id. at 6:55–57. These are examples of updated video-game content (updated advertisements on posters, T-shirts, and chalk boards) that are usable (e.g., by the game or mobile communication device executing the game) in a video game that already exists on the mobile communication device. These are also examples of what Patent Owner argues are “skins” that correspond to existing ad units and that do not alter any function of the game. Patent Owner’s construction, then, would exclude the ’202 patent’s preferred embodiment. “Such an interpretation is rarely, if ever, correct and would require highly persuasive evidentiary support, which is wholly absent in this” slip op. at 12

    “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 “[e]ach of Hays and Choi 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 ’202 Patent.” PO Resp. 56. Patent Owner argues that a prior art reference under pre-AIA 35 U.S.C. § 102(e) is a printed publication under Section 311(b) only as of its publication date and not as of its filing date. Id. at 56–58. 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. And, by virtue of § 102(e)(1), 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 permissible grounds of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–9 are unpatentable under 35 U.S.C. § 103(a) on the basis of Hays or Hays and Choi, which are prior art printed publications.” slip op. at 16

In the soft drink example, “the advertisement management service system may send bots or electronic agents into the game as advertising units or real characters in the game.” Ex. 1005 ¶ 79. Thus, the service system inserts more than a skin; it inserts a bot or agent that was not part of the game before its insertion. Because Dr. Akl’s testimony (Ex. 2004 ¶¶ 63–64, 72–73) is inconsistent with Hays’s disclosure, we do not credit it. See Homeland Housewares, LLC v. Whirlpool Corp., 865 F.3d 1372, 1378 (Fed.

    “We are not persuaded, on this record, that Petitioner adequately establishes that Khatibi discloses a CTE in the claimed range of 16 to 22 µm/(m·°C.). Petitioner’s argument that Khatibi’s reported values meet this claim limitation are based solely on Dr. Randall’s testimony that Khatibi’s measurement method would produce results that would not significantly differ from results determined using the claimed method. See Pet. 16–18 (citing Ex. 1003 ¶¶ 56–60). Dr. Randall’s testimony, however, is largely conclusory and unsupported by adequate explanation and/or objective evidence. For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added). to little weight.

    “second surfaces of the electrolytic copper foil ranges from 3 to 92.” Ex. 1001, 13:62–63. Petitioner contends that “Kim teaches that the electrolytic copper foil (e.g., untreated or treated copper foil) having Rz less than 2 µm is advantageous toward battery efficiency and performance,” and, similarly, Griesi describes the use of untreated electrolytic copper foil with an Rz value less than 2 µm in printed circuit boards that are compatible with secondary batteries. Pet. 58–59 (citing Ex. 1012, claim 2, ¶¶ 13, 25, 27; Ex. 1003 ¶ 157). In particular, Petitioner notes that Griesi’s Figure 3.16 describes an “Rz value of 1.2 µm.” Id. at 59 (citing Ex. 1015, 53–54; Ex. 1003 ¶ 158). Petitioner asserts that “Dr. Randall explains that a POSITA would have also recognized another surface roughness-related parameter, Rpc, in Griesi as a potentially useful parameter that can be optimized to further enhance uniformity or generally improve Kim’s copper foil surface, for example, to prevent wrinkles or achieve other advantageous effects.” Id. (citing Ex. 1003 ¶ 159). Although Dr. Randall demonstrates that Griesi’s Pc (or Rpc) value is 19.2 over a 4 mm sampling length (Ex. 1003 ¶ 155), Petitioner does not contend that Griesi addresses this value, or indicates any benefit that might be derived from its use. Instead, Griesi’s Pc value appears to be an incidental finding, which is not discussed or analyzed in the reference. See incidental, unexamined finding would lead a POSITA to import Griesi’s Pc value into Kim’s copper foil, absent a hindsight desire to reconstruct the claimed invention. As such, Petitioner’s arguments with respect to Kim and Griesi are not persuasive. See Cheese Sys. Inc. v. Tetra Pak Cheese and Powder Sys., Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013) (“Obviousness cannot be based on the hindsight combination of components selectively culled from the prior art to fit the parameters of the patented invention.” (internal quotations marks omitted)).

    “A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A.
