Examples of such portable devices are provided as wireless telephones, PDAs, laptops; handheld devices, and music players. Ex. 1009 ¶ 22; See Ex. 1001, 4:22−28 (describing a visor as a portable gaming system); 7:21−27 (listing additionally Blackberries, Personal Electronic Devices, IPODs and any other portable electronic device, to be configured as a gaming system). Taking these disclosures together, the ’243 patent does not define the degree of the “portability” of the claimed device to require that the “portable device” must be completely “free of encumbering external connections.” If “portability” can include integrating a component of the “portable device” into a “non-portable device,” then there is support for holding that the recited “portable device” could be tethered to a non-portable device.” slip op. at 8

“rotation sensors are found not to be positioned on Levesque’s display, it would have been obvious to do so in light of Ronzani because Ronzani teaches equipping the head-mounted device with external and internal sensors). Petitioner’s arguments and evidence regarding motivation to combine amount to showing that “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007).

“A reference that is in the same field of endeavor as the claimed invention is analogous art,5 and such a qualification means that one of ordinary skill in the art is presumed to have been aware of the reference and thus the refence properly may be considered if it predates the claimed invention. See Circuit Check Inc. v. QXQ Inc., 795 F.3d 1331, 1335 (Fed. Cir. 2015). Petitioner contends that the field of endeavor of the claims of the ’243 patent is “the field of portable user-worn devices for providing location based-entertainment.” Pet. 19−20. According to that description of the relevant field of endeavor, Petitioner argues that both Levesque and Ronzani are analogous to the ’243 patent. Id. Patent Owner appears to argue that the field of endeavor is “video games.” Prelim. Resp. 29−30. This is not the correct field of endeavor because although the claim recites a location based game system, the claims considerably focus on the head-mounted device. Indeed, for claim 1 all the structural elements claimed involve or are placed in the head-mounted device. Thus, “video games” generally is not an appropriate field of endeavor, as it is too broad and ignores the significant focus of the claims of the ’243 patent. Petitioner’s statement of the field of endeavor is, therefore, more indicative of the correct field of endeavor involved here. And as such, it is unpersuasive to argue that Ronzani does not belong to the field merely because it is not solely focused on video” slip op. at 18

“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 Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted 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. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator.

“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[6] 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).” slip op. at 4

“At this point in the proceeding, we do not agree with Patent Owner that the recited survey module must be autonomous, self-contained, or a web-container package. As discussed above, we preliminarily interpret this term to mean software code for displaying a survey question. We find no support in the current record to add to this definition any additional requirements related to autonomy, self-containment, or a web-based context for the survey module. The Petition (at 19) points to Douglas as teaching the claimed survey module, i.e., in Douglas, software sent to the customer for taking a product survey on the display of the customer’s computer device. Douglas teaches, in response to a customer providing a survey trigger (e.g., purchase data signals), a survey generator creates a transaction-specific survey (e.g., “Was the item you found too expensive?”) and transmits it to the customer’s device (e.g., a mobile phone with a touchscreen); the survey is interactive; and the customer touches or clicks their device’s screen to respond to the survey questions.

Moreover, Douglas also discloses that its survey “interact[s] with the customer using one or more software applications on customer device 106,” which may be, e.g., a computer or mobile phone, further, “[t]he one or more software applications may be provided by survey system 101, or merchant 107, or a third party,” and finally, “[t]he one or more software applications may be web-based applications and/or native mobile applications installed on the customer device 106.” Id. ¶¶ 18–20; see also Prelim.

Id. Petitioner responds “(1) Fogarty did not indicate the catheter’s size; (2) Fogarty catheters smaller than 6 Fr were known and disclosed in Chengod (and Deaton); and (3) sizing Fogarty’s catheter less than 6 Fr would work (i.e., reasonable expectation of success) because it did work.” Pet.

Regeneron Pharms., Inc. v. Mylan Pharms. Inc., 127 F.4th 896, 914 (Fed. Cir. 2025); Ariad, 598 F.3d at 1351. In this case, Table A of the ’935 provisional discloses a list of CH3 domain interface residues and identifies, for each interface residue in heavy chain A, the contacting residue in the corresponding chain B. Ex. 1030, 17, Table A. Table A does not, however, describe any particular substitutions or pairs of substitutions that should be made to the CH3 domains. See, e.g., Pet. 28 (citing Ex. 1002 ¶¶ 109–119). Table 7 of the ’935 provisional does identify specific amino acid substitutions in CH3 domains, including substitutions resulting in a positively charged residue at position 364 (e.g., S364K) and a negatively charged residue (e.g., L368D) at position 368. Ex. 1030, 52, Table 7. Patent Owner argues that this table “discloses specific positions for ‘identification of novel charge pair mutants.’” Prelim. Resp. 13 (citing Ex. 2010 ¶ 48). As Petitioner points out, however, while Example 13 of the ’935 provisional relates to identification of novel charge pair mutants, Table 7 itself was only a “first step” in this identification process. Ex. 1030, 51:6–17. In this step, “many interface contact residues in the IgG CH3 domain were scanned one by one or in groups for substitutions that would result in repulsion of 35 identical heavy chains” so that identified substitutions can then be used to generate antibodies “by engineering matched pairs of CH3 residues in one or more IgG heavy chains – CH3 regions” in follow up experiments. Id. Accordingly, Table 7 does not appear to describe heterodimer combinations, such as those that would result from a pairing of chains with different substitutions. Pet. 29–30 (citing, e.g., Ex. 1002 ¶¶ 111–118). As Petitioner further points out, the follow up experiments testing the matched pairs of CH3 residues did not include paired substitutions at positions 364 and 368. Id. at 29–31. Patent Owner points to disclosure in the ’935 provisional describing, as a distinguishing feature of its invention, the substitution of non-charged or neutral amino acids in wildtype CH3 with charged residues, which according to the ’935 provisional has the “advantage that at least one additional charge-charge interaction in the CH3 interface is created.” Prelim. Resp. 12 (citing, e.g., Ex. 2010 ¶¶ 42–48). For the same reasons discussed above, Petitioner has sufficiently established, for purposes of institution, that such disclosure would not reasonably convey to an ordinarily skilled artisan that the inventors had possession of the entire genus of heterodimeric antibodies comprising CH3 domains wherein a non-charged amino acid is replaced with a charged residue so as to create an additional charge-charge interaction in the CH3 interface.

“The ’859 patent does not provide an explicit definition of “immunoglobulin class.” Nevertheless, we do not construe that term to require “two heavy chains with four domains, VH, CH1, CH2, and CH3, and two Fab arms.” As an initial matter, the Specification teaches that antibodies include, 16 e.g., IgE and IgM — which have an additional CH4 domain in their heavy chains — as well as functional derivatives and/or fragments of known antibody isotypes. Ex. 1001, 11:44–48. Patent Owner’s proposed construction, which limits antibodies to those having two Fab arms and “two heavy chains with four domains, VH, CH1, CH2, and CH3,” excludes these embodiments and cannot be correct. Moreover, the ’859 patent defines antibody as containing “one or more domains” that bind an epitope on an antigen. Ex. 1001, 11:39–44. Thus, an antibody does not require two Fab arms as in a native immunoglobulin molecule.12 The ’859 patent also describes a preferred embodiment as “Ig-like molecules.” Id. at 11:49–52. Thus, we look to the definition of “Ig-like molecule” in the ’859 patent, i.e., “a proteinaceous molecule that possesses at least one immunoglobulin (Ig) domain,” to inform our understanding of the phrase “immunoglobulin class of proteins.” Ex. 1001, 11:4–6. Accordingly, we further construe “immunoglobulin class of proteins” to mean proteinaceous molecules comprising at least one domain that is derived from or shares sequence homology with an immunoglobulin domain.” slip op. at 16

“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).

Petitioner’s argument and evidence, at this juncture, reasonably explain the reasons to combine under precedent that there is a motivation to combine when “a known technique ‘has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way.’” See Intel Corp. v.

“At this stage, we do not find Patent Owner’s proposed construction persuasive for several reasons. The claim does not recite “a defined physical playfield.” Rather, the claim recites “a physical playfield.” The Paper 10 in the 740 IPR; and Patent Owner filed a Preliminary Sur-reply, filed as Paper 11 in the 740 IPR. Specification’s discussions of “playfield” cited by Patent Owner use non-limiting language such as “for example” and “may” in describing the playfield. Ex. 1001, 2:38−40, 2:63–3:2, 3:23–25, 6:11−13, 6:46−48, 8:48– 62, 9:23–28, 20:28−58, 22:1−4. The disclosed examples of “a physical playfield” include “the physical world, a physical environment, or a defined physical playfield” (740 Ex. 1001, 1:58−60), which indicates that applicant intended “a physical playfield” as claimed to encompass more than a defined, or “bounded” physical playfield. This indication is consistent with the Specification’s disclosure that “the game world corresponds to an actual area of the physical world (such as the planet Earth or New York City).” 740 Ex. 1001, 11:12−14. Thus, in one disclosed embodiment, the physical playfield is the entire (unbounded) world. We are persuaded that the Specification’s descriptions of various embodiments with defined playfields and undefined playfields support construing the scope of a “physical playfield” as encompassing a physical playfield with defined boundaries, or a “bounded” playfield, as well as a physical playfield with undefined boundaries, or an “unbounded” playfield. Limiting the claim term to only “bounded” play spaces would read out broader embodiments from the claim scope. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed. Cir. 1996) (holding that interpreting a claim to exclude an embodiment disclosed in the written description “is rarely, if ever, correct and would require highly persuasive evidentiary support, which is wholly absent in this case.”).

“physical playfield” as properly construed. Prelim. Resp. 30. As discussed in our claim construction above, we are not persuaded that the claim term “physical playfield” is limited to a bounded physical play space. However, even under the Patent Owner’s proposed narrower construction, we are sufficiently persuaded that the combination teaches a bounded physical play space. Jaszlics discloses that its system creates virtual elements in theme parks and entertainment-oriented environments. Ex. 1003, 2:14–16, 2:67– 3:1; see id. at 18:48–55. We are sufficiently persuaded that a theme park is a bounded physical play space. In addition, Jaszlics discloses training armored vehicle crews by using both virtual vehicles and actual vehicles moving over real terrain. Ex. 1003, 1:38–60. We are sufficiently persuaded that a skilled artisan would have envisioned that such training occurs on a military base, which is bounded.8 Jaszlics further discloses that its training field includes boundary markers. Ex. 1003, Fig. 15, 10:1–9. We are sufficiently persuaded that the tank training field of Jaszlics, which has boundary markers and is located on a military base, is a bounded physical play space. Therefore, even under Patent Owner’s narrower construction, we are sufficiently persuaded that a person of ordinary skill would have recognized that a user would have played at least some of the video games provided by the combined system of Jaszlics and Piekarski in a bounded physical play space such as a theme park or a military base. slip op. at 9
