      “E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight. Instead, we assess Dr. Doolittle’s testimony on a case-by-case basis as discussed below.” slip op. at 21

      “The ’286 patent uses the term “heavy chain” or “heavy chains” repeatedly; however, we find no express definition of the term. See generally Ex. 1001. Rather, the ’286 patent uses the term “heavy chain” in relation to antibody structure in a way that suggests the term is standard and well known in the art. See, e.g., id. at 3:19–59 (Background). The parties’ briefing on the technology reinforces this fact. See Pet. 5–14 (“The basic structure of natural IgG comprises four protein chains—two identical heavy chains (shown in red) and two identical light chains (shown in blue)—which are arranged in a Y-shaped configuration: . . . (EX1013, 112-13; EX1002, ¶¶23-30.)”); Prelim. Resp. 3–4 (“Natural or wild type Igs have a particular structure made of two identical light (L) chains and two identical heavy (H) chains. See EX2008 at ¶ 23. Each Ig heavy chain consists of three constant domains (CH1, CH2, and CH3) and one variable domain (VH), which is also isotypes, or a functional derivative and/or fragment of these. In a preferred embodiment, Ig-like molecules are produced that are antibodies of the IgG isotype because IgG antibodies e.g. have a longer half life as compared to antibodies of other isotypes. Ex. 1001, 11:9–21. As noted above (see supra Section I.C), IgG antibodies’ heavy chains have three constant domains, but IgE and IgM have four. Thus, Patent Owner’s argument that heavy chain means one variable and three constant domains, and two differently-binding Fab arms, ignores embodiments of the invention. consistent with the definition of heavy chain in the ’286 Patent. See EX2008 at ¶ 24; EX1001 at 11:58–66.”). This is also how the ’286 patent generally uses the term. See Ex. 1001, 11:58–12:1. But, the Specification does not limit its embodiments to only IgG antibodies because it also describes that the invention may be “IgG1, IgG2, IgG3, IgG4, IgA, IgE, and IgM” type antibodies, and fragments. Ex. 1001, 11:9–21; see also supra n.10 (quoting the ’286 patent’s definition of antibody). Other embodiments would not necessarily have the heavy chains as argued by Patent Owner. There is no evidence of record that the ’286 patent’s claims or the Specification generally use or limit the term “heavy chains” (or “heavy chain”) in any way deviating from its ordinary and customary meaning in the art. Therefore, at this stage of the proceeding, we decline to expressly interpret this claim language. 2. Summary on Claim Construction At this stage of the proceeding, we expressly construe no claim terms and give each claim term the ordinary and customary meaning it would have had to the person of ordinary skill in the art as of the invention date. See Nidec Motor Corp., 868 F.3d at 1017. If either party intends to further argue claim construction at trial, they should do so in a clearly designated section of their briefing so as to expressly identify such arguments. See, e.g., 37 C.F.R. § 42.104(b)(3) (content of petition); see also Board’s Consolidated Trial Practice Guide (CTPG) at 46, 48–45 (Nov. 2019).12 Claim construction arguments should not be relegated to patentability arguments on the facts.” slip op. at 16

      “In brief summary, these limitations require one CH3 heavy chain to have a positive amino acid substituted in place of a neutral one, the other CH3 heavy chain to have a negative amino acid substituted in place of a neutral one, and that when the heavy chains are expressed by culturing the host cell these positive and negative amino acids interact and the antibody produced is a heterodimeric antibody. Petitioner asserts that Lazar expressly teaches engineering two CH3 domains so that, when expressed, they interact and form a heterodimeric CH3 interface by making neutral-to-positive and neutral-to-negative amino acid substitutions at known interacting residues on each CH3 domain, e.g., S364E (changing neutral serine to negative glutamic acid at residue 364) on one CH3 domain, and L368K (changing neutral leucine to positive lysine at residue 368) on the other CH3 domain; or T366D (swapping neutral threonine for negative aspartic acid at residue 366) on one CH3 domain and L351K (swapping neutral leucine for positive lysine at residue 351) on the other CH3 domain; that these residues were known in the art to be respective interfacing contact residues; that these modifications favor Fc heterodimerization; and that they result in a heterodimeric antibody (proof-of-concept shown by synthesizing and screening).

      “The definition of a person having ordinary skill in the art that we adopted in the Institution Decision is supported by the testimony of Dr. Akl. Ex. 1003 ¶ 22. Patent Owner states that it agrees with that definition, while also proposing a broader definition that includes those with other qualifications. PO Resp. 2. Although Patent Owner argues that “the supporting evidence [for its addition] is broadly present in the case, namely, in the Patent-in-Suit and the associated intrinsic evidence” (PO Sur-reply 3 n.6), Patent Owner does not direct us to any specific portion of the record. See United States v. Dunkel, 927 F.2d 955, 956 (7th Cir. 1991) (“Judges are not like pigs, hunting for truffles buried in briefs.”); DeSilva v.

Patent Owner’s use of its definition does not describe the conclusions of one “educated in general physics” differently to one of ordinary skill as defined by Petitioner. PO Sur-reply 6. Patent Owner does not present declarant testimony regarding knowledge of one of ordinary skill in the art under any definition.3 For these reasons, we maintain the definition of a person having ordinary skill in the art we adopted in the Decision on Institution: a person having ordinary skill in the art would have had experience in the hardware and software used in the field of securely transmitting and processing authorization requests over wired and wireless networks, such as requests for the processing of financial transactions, and a bachelor’s degree in computer science, computer engineering, electrical engineering, or a related study, and would have one or two years of experience with wired and wireless 3 See infra footnote 5. as financial transactions.

      “Having analyzed the arguments and the evidence cited by Patent Owner, we do not agree. We begin with the claim language, which does not further describe the two transmission channels, let alone contradict the plain meaning. Ex. 1001, 6:5–19. Dependent claims also shed no additional light. Certain claims further specify transmission-channel-related requirements: that the first transmission channel be “selected from the group consisting of wireless and landline channels” (claim 7); that the request received via the first transmission channel be “provided via the Internet” (claim 5); or that the notifying step (via a second transmission channel) comprise “sending an SMS message to the customer (claim 2). Id. at 6:20–21, 6:28–29, 6:33–35. No claims further restrict claim 1 by describing both transmission channels. Id. Claim 9 requires that the notification be “substantially concurrent,” but nothing in the record establishes that substantially concurrent authorization and notification would require non-overlapping transmission channels, or that an overlap in the transmission channels, even if it did “encumber” the authorization process with the notification process, would prevent the processes from being “substantially concurrent.” While Patent Owner presents arguments about “the gist” of the invention (PO Resp. 4) and describes “an immediate separation of the two processes” as being disclosed by Figures 1 and 2 of the ’564 patent’s specification, we do not see in the specification an indication of a special disavowal of a broader scope. See Phillips, 415 F.3d at 1316–1317; PO Resp. 13 (“The specification of the ‘564 Patent does not express any intent to impart a novel meaning to the term distinct.”). Although we agree with Patent Owner that Figure 1 illustrates transmission channels that are separate and non-overlapping, we do not see any indication that this is more than a description of preferred embodiments or that there was a limitation of the invention to these embodiments, and our reviewing court “has repeatedly ‘cautioned against limiting the claimed invention to preferred embodiments or specific examples in the specification.’” Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1346–47 (Fed. Cir. 2015) (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1328 (Fed. Cir. 2002)).

      “Patent Owner further argues Nakazawa teaches away from Petitioner’s asserted modification in which Glaug’s lower non-perforated layer is added to Nakazawa’s diffusion sheet. Prelim. Resp. 42. Specifically, Patent Owner argues Nakazawa teaches that its embodiment in which the second absorbent material is wrapped in a hydrophilic sheet has the advantage of preventing leakage of super absorbent polymer (“SAP”) from the second absorbent material without impeding permeation of excretory fluid through the hydrophilic sheet. Id. at 43 (citing Ex. 1008 ¶ 85, Fig. 15). Patent Owner further relies on Petitioner’s argument that Nakazawa’s hydrophilic layer is analogous to the lower non-perforated layer in Glaug. Id. (citing Pet. 93–94). Therefore, Patent Owner argues, Nakazawa teaches that Glaug’s fluid acquisition system would impede permeation of fluid rather than promote it. Id. Patent Owner’s teaching away argument is unavailing based on the current record. Patent Owner improperly relies on Petitioner’s contention in its anticipation challenge based on Nakazawa, and characterizes it as an argument about Glaug. As further discussed in Section II.G below, Petitioner’s anticipation challenge is based on analogizing Nakazawa’s hydrophilic sheet to a core wrap feature identified in Patent Owner’s infringement contention in parallel district court litigation. See Pet. 92–93. Contrary to Patent Owner’s argument, Petitioner’s obviousness contention does not argue Nakazawa’s hydrophilic layer is analogous to Glaug’s nonperforated fibrous layer. Because Patent Owner is not properly characterizing Petitioner’s obviousness contention, Patent Owner’s teaching away argument is not persuasive.” slip op. at 24

Neither party argues, at least at this stage of the proceeding, that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art.

      “Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Resp. 4). In determining at this stage of the proceeding that Petitioner has demonstrated a reasonable likelihood of establishing unpatentability of at least one challenged claim (namely dependent claim 11 in this case), we need not and do not construe expressly any claim terms. Nevertheless, we encourage the parties to submit proposed constructions for the limitation “determining a UE [i.e., User Equipment] environment information,” as recited in dependent claim 11. See Ex. 1001, 49:12–15, 1:40–42 (emphasis added). To the extent that a party proposes that this limitation should have its ordinary and customary meaning, the party should submit and explicitly identify such meaning. O2 Micro Int’l Ltd. v.

For example, the parties should discuss (a) the meaning and scope of “determining” as used in the subject limitation; (b) the meaning and scope of “environment information” as used in the subject limitation; (c) any relationship or overlap between “environment information” and “link quality positioning information,” as recited in dependent claims 7 and 11 (see Ex. 1001, 48:62–65, 49:12–15); and (d) whether UE “environment information” includes location or orientation of the UE.” slip op. at 10

      “Petitioner contends the skilled artisan would have had rational reasons to combine the teachings of Jarvinen and Fox to arrive at the invention of dependent claim 11 (which includes the features of independent claim 1 and dependent claim 7) and would have had a reasonable expectation of success in doing so. Pet. 37–41; see, e.g., id. at 38 (“[The skilled artisan] faced with the problem of estimating a UE’s future link quality at a location would have looked to Fox because Fox solves the problem of estimating future link quality with the exact same information available to Jarvinen.”); Ex. 1012 ¶ 70 (Dr. McClellan testifying that “[a]ll of the data upon which Fox relies is already disclosed and linked together in Jarvinen’s database, and it would have been obvious for [the skilled artisan] to combine Fox’s method of looking up previous link quality to estimate future link quality with Jarvinen’s teachings.”); ¶ 72 (Dr. McClellan testifying that “modifying Jarvinen to perform Fox’s link quality estimation would have constituted a simple substitution of a known element to yield predictable results.”). Patent Owner does not dispute such reasons or expectations at this stage of the proceeding. For the reasons and evidence set forth in pages 37–41 of the Petition, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox to arrive at the invention of claim 11, and to do so with a reasonable expectation of success. c) Summary At this stage of the proceeding and based on the record before us, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox with a reasonable expectation of success, and sufficiently supports Petitioner’s contention that dependent claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox. Thus, for the foregoing reasons and those stated in Petitioner’s preliminary briefing (Pet. 17–47, 50–51, 54), we determine that Petitioner has established a reasonable likelihood that it would prevail in showing that claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox.” slip op. at 18

If a different level of skill would affect the outcome in this case, the parties must brief that issue as well. The failure of Patent Owner to describe how a different level of skill in the art is determinative will be a forfeiture of that argument.

      “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

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.

    • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

      “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
