      “question, based on factual findings. VidStream, 981 F.3d at 1063–64. Moreover, public accessibility is the touchstone in determining whether a reference is a printed publication and such depends on whether the reference was available to interested, ordinarily skilled persons exercising reasonable diligence, which is determined on a case-by-case basis. Id. at 1065. Particularly pertinent here is that “[w]hen there is an established publisher there is a presumption of public accessibility as of the publication date.” Id. Hulu (which cites VidStream on this issue) concerned, inter alia, whether certain asserted references were shown to be publicly available and could be considered as prior art. Hulu, 2021 WL 487622. Hulu holds that, although testimonial evidence is one way to prove public accessibility, there are also a variety of hallmarks of publication and other evidence that may be considered as a totality of the evidence to determine if an asserted reference was publicly accessible and prior art. Id. at *10–13, 21. Facts to be considered in analyzing the issue, other than testimonial evidence, include, for example, whether there is an established publisher, a copyright date/notice, other publication-related dates (impression, printing, etc.), an ISBN number, citations to the reference before (and to a lesser degree, after) the priority date at issue corroborating its availability and/or that the publisher was established, and whether the reference’s “purpose of publishing . . . was ‘dialogue with an intended audience.’” Id. at *10–21 (citing Valve Corp. v.

      “These two proposed definitions of the ordinarily skilled artisan share many consistencies, for example, the types of degrees and experience such a person would have had, but differ in the number of years of experience. Petitioner proposes the ordinarily skilled artisan would have had at least five years of experience and Patent Owner proposes at least three years (which would necessarily include five years, too). Patent Owner also proposes that the ordinarily skilled artisan would have consulted a dentist, oral surgeon, prosthodontist, or periodontist with experience in dental implants and prosthetics. At this point, we find little meaningful difference between the two proposed definitions.

    • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateNot entitled to earlier dateDecided for petitioner

      “Here, the first claim limitation at issue is broad, i.e., different thread pattern/profile between a definite and a temporary screw, and the Specification’s and priority applications’ disclosure is narrow and specific, asymmetric buttress style threads in a temporary screw and symmetrical threads in a definite screw (are different). Any apparent predictability in or maturity of the relevant field here must be contrasted with the fact that the Specification, considering the ’992 patent itself or any of the identified priority applications, never once even discusses the (claimed) concept of specifically differing the thread style between a temporary and a definitive screw. Any differences in thread style are not called out by the disclosure, but are described and can be discerned only in relation to the respective threads’ functionality, i.e., Fig. 75’s temporary screw 190 has buttress-style threading so it can be pulled out rather than unscrewed from the abutment; Fig. 9’s definitive screw 75 has male threads that fill the female threads of the abutment 8 for a secure permanent engagement. Ex. 1001, 15:23–30, 21:25–44, 23:3–36; Ex. 1012, 97–98, Figs. 9, 75. And, although it is possible for a single disclosed species to provide written description support for a claimed genus, “a sufficient description of a genus . . . requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can ‘visualize or recognize’ the members of the genus.” Ariad, 598 F.3d at 1350; see also Synthes USA, LLC v. Spinal Kinetics, Inc., 734 F.3d 1332, 1344 (Fed. Cir. 2013). That does not appear to be the case here—the present record does not support that the described asymmetrical buttress, serrated style of different temporary screw threading (relative to that of the definitive screw and regardless of the direction of the threads for rotation) is sufficiently representative of the genus’s “different” thread patterns/profiles. See, e.g., Ex. 1006 (a buttress style thread does not function the same as a buttress reverse or 75º joint profile or rounded, or trapezoidal thread).” slip op. at 30

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “As Petitioner points out, the cited disclosure in the ’935 provisional does not “mention[] positions 364 and 368 together as a pair of positions for potential mutations on two chains.” Pet. 28 (citing Ex. 1002 ¶¶ 109–19). Although Patent Owner is correct that examples or actual reduction to practice are not required for adequate written description and “[a] specification may . . . contain a written description of a broadly claimed 34 invention without describing all species that [the] claim encompasses,” Prelim. Resp. 15 (quoting Ariad Pharms., 598 F.3d at 1352 and Cordis Corp. v. Medtronic AVE Inc., 339 F.3d 1352, 1365 (Fed. Cir. 2003)), the ’935 provisional must still “reasonably convey[] to those skilled in the art that the inventor[s] had possession of the claimed subject matter” as of the relevant date. 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. In this regard, we also note that “a description that merely renders the invention obvious does not satisfy the [written description] requirement.” Ariad, 598 F.3d at 1352.” slip op. at 34

Having considered the evidence of record at this preliminary stage of the proceeding, and for the reasons set forth below, we are persuaded that Petitioner has shown sufficiently, for purposes of institution, that the ’935 provisional does not provide adequate written description support for claim 1 of the ’859 patent and that, accordingly, Desjarlais and Moore qualify as prior art to that claim. As Petitioner points out, the cited disclosure in the ’935 provisional does not “mention[] positions 364 and 368 together as a pair of positions for potential mutations on two chains.” Pet. 28 (citing Ex. 1002 ¶¶ 109–19).

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “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

      “insufficient to support the concept of alerting a user that the user is leaving a virtual environment. In so deciding, we need not address the parties’ contentions about boilerplate. Regardless of whether the sentence at 168:15–16 of the ’140 application is boilerplate, we agree with Petitioner that “there is no suggestion of the specific claimed combination.” Reply 22 (citing Ex. 1146 ¶ 82). That is, if one views the “[e]xamples herein” from Figure 6 as taking place “in computer rendered spaces (VR)” or “in partially computer rendered spaces (AR),” there is still no disclosure of alerting a user that a user is leaving a virtual environment. See Ex. 1028, 168:15–16. For instance, if Alice in the Figure 6 example mentioned above is entering a virtual car instead of a real car, Alice is still in a virtual environment. See id. at 120:13–27. Thus, relying on Figure 6 to take place “in computer rendered spaces (VR)” does not support alerting that a user is leaving those virtual spaces. See id. at 168:15–16. Petitioner also correctly identifies a problem with analogizing the Alice example to a virtual environment—namely, it would no longer make sense to give Alice an audible warning. See Reply 22 (citing Ex. 1146 ¶ 82). In the example, Alice’s earphones switch from binaural sound to mono sound when Alice enters a real car because “[t]he state where Alice is located . . . prohibits drivers from localizing sound while driving a motorized vehicle.” Ex. 1028, 120:15–18. But it would not make sense (nor does the ’140 application disclose) for a state to prohibit Alice to localize sound while driving a virtual vehicle. We therefore find compelling Petitioner’s argument, supported by the testimony of Dr. Roginska, which we credit, that there is no “disclosure that 3D audio would not be permitted in a 3D virtual space.” Reply 22 (citing Ex. 1146 ¶ 82).

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “One benefit Petitioner proposes to support a rationale to combine is that a POSITA “would have implemented this feature to help protect the users from injury by bumping, hitting, tripping over, etc., real-world objects when moving around while viewing the virtual environment in the HMD (i.e., a type of head-mounted WED).” Id. at 43–44 (citing, e.g., Ex. 1003 ¶¶ 90, 251–254). Petitioner provides additional argument and evidence supporting a motivation to combine, with a reasonable expectation of success. See id. at 42–46. We agree that, in the combination, a POSITA would have implemented Lyren’s audible alerts to alert the user that the user is leaving Reif’s safe zone (and thus the virtual environment) to help keep users safe. Id. at 52 (citing Ex. 1003 ¶¶ 250–268). We also agree with Petitioner’s articulated benefit that the combination would “help protect the users from injury by bumping, hitting, tripping over, etc., real-world objects when moving around while viewing the virtual environment in the HMD (i.e., a type of head-mounted WED).” Id. at 43–44. Accordingly, we agree with Petitioner that the combination of Lyren and Reif discloses each limitation of claim 14, as well as similar limitations of claims 1 and 7, and that one of ordinary skill in the art would have combined Lyren and Reif in the manner proposed, with a reasonable expectation of success.” slip op. at 24

We conclude that no claim of the ’179 patent is entitled to priority to the ’140 application.” slip op. at 22

      “We agree that, in the combination, a POSITA would have implemented Lyren’s audible alerts to alert the user that the user is leaving Reif’s safe zone (and thus the virtual environment) to help keep users safe. Id. at 51 (citing Ex. 1003 ¶¶ 250–263). We also agree with Petitioner’s articulated benefit that the combination would “help protect the users from injury by bumping, hitting, tripping over, etc., real-world objects when moving around while viewing the virtual environment in the HMD (i.e., a type of head-mounted WED).” Id. at 43. Accordingly, we agree with Petitioner that the combination of Lyren and Reif discloses each limitation of claim 14, as well as similar limitations of claims 1 and 7, and that one of ordinary skill in the art would have combined Lyren and Reif in the manner proposed, with a reasonable expectation of success.” slip op. at 26

      “understanding of a person of ordinary skill in the art at the time of the invention. Graham v. John Deere Co., 383 U.S. 1, 17 (1966). For purposes of this proceeding, Petitioner argues a person of ordinary skill in the art at the time of the invention would have had “a bachelor’s degree in computer science, computer engineering, or equivalent with one to two years of experience in the field of mobile transactions.” Pet. 8 (citing Bederson Decl. ¶¶ 35–37). Petitioner adds that “[a]dditional education or experience might substitute for the above requirements.” Id. To the extent necessary, and for purposes of this Decision, we accept this assessment offered by Petitioner, as it is supported by Dr. Bederson’s testimony and appears consistent with the ’578 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “scanner, reader, or camera” that is aimed at a barcode or special code of a product, the price of which is then added to the retail bill. Pet. 10–11 (quoting Ex. 1001, 7:45–49, 9:5–11). According to Petitioner, the Specification does not elaborate further on the meaning of the term “information concerning prices of goods.” Id. at 11. Petitioner, thus, interprets the term to encompass scenarios in which price information is received directly or indirectly. Id. Petitioner notes that during prosecution of the ’578 patent, the Examiner rejected this limitation over prior art, stating that prior art “sends the scanned bar code information to the server,” which “then preferably returns a description of the item and information,” and “[t]his item description and price information is displayed on the telephone’s display.” Id. at 12 (quoting Ex. 1002, 231). According to Petitioner, this is an example of indirectly receiving information concerning the prices of goods as it comes from a queried server, not from the item itself. Id. Petitioner notes that Patent Owner never disputed, and in fact, made statements supporting that these actions were encompassed by the claim limitation. Id. (citing Ex. 1002, 214). We agree with Petitioner that nothing in the claim language or the Specification requires that the claimed optical input receive information concerning the prices of goods directly from the goods themselves. Thus, on this record, we preliminarily construe the term “receiving information concerning the prices of goods” to encompass receiving pricing information from a server.” slip op. at 9

With respect to entitlement to any earlier effective filing date, however, a patent owner is not presumed to be entitled to the earlier filing dates of ancestral applications that do not share the same disclosure, such as in a continuation-in-part situation.

      “Under 35 U.S.C. § 324(a), a post-grant review may be instituted only if “the information presented in the petition . . . demonstrate[s] that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” Post-grant review is available for patents that issue from applications that at one point contained at least one claim with an effective filing date on or after March 16, 2013. See Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), §§ 3(n)(1), 6(f)(2)(A). After considering the briefing and the evidence of record, for the reasons set forth below, we determine that Petitioner has shown that the ’947 patent is eligible for post-grant review, and has shown it is more likely than not that at least one challenged claim of the ’947 patent is unpatentable under § 324(a). Accordingly, we institute a post-grant review of the challenged claims of the ’947 patent.” slip op. at 2

      “Petitioner contends that a person of ordinary skill in the art “would have a B.S. degree in Electrical Engineering, Physics, Chemistry, or an equivalent field, and at least 2-3 years of academic or industry experience in engineering related to optical sorting systems.” Pet. 17 (citing Ex. 1009 ¶ 21). Patent Owner did not file a Preliminary Response to the Petition and, therefore, at this point, does not contest Petitioner’s definition for one of ordinary skill in the art. Petitioner’s proposed definition appears to be consistent with the disclosure of the ’947 patent, and we adopt it for purposes of this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Having considered the record, we determine that no express claim construction is necessary for any claim terms for the purposes of rendering a decision to institute trial. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (holding that only claim terms in controversy need to be construed, and only to the extent necessary to resolve the controversy (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). At this stage, we find it unnecessary to resolve whether “electronic control unit” and “processing module” should be construed as mean plus function limitations under § 112(f), because it is possible to address the obviousness grounds presented whether or not these limitations are so construed, and even if the claims were indefinite in the manner Petitioner contends. See Intel Corp. v. Qualcomm Inc., 21 F.4th 801, 813 (Fed. Cir. 2021) (noting indefiniteness of a means-plus-function limitation does not always render it impossible to adjudicate a prior-art challenge).

      “(3) Conclusion – Written Description In view of the above, we find that either disclosure in Barsoum identified by Patent Owner satisfies the written description requirement. 2. 35 U.S.C. § 103 As noted previously, Petitioner argues that dependent claims 5, 15, and 25 are obvious over the combination of Barsoum and ATSC327. Pet. 67–79. Having determined the Barsoum provides written description support for claims 5, 15, and 25, Barsoum cannot be prior art under 35 U.S.C. §102(a)(1) as asserted by Petitioner. Pet. 2; 35 U.S.C. § 102(a)(1) (requiring that “the claimed invention was patented . . . before the effective filing date of the claimed invention). Furthermore, having determined that the ’700 patent is entitled to an effective filing date of Barsoum ’777, which is June 5, 2008, the asserted March 2019 date of ATSC327 does not qualify it as prior art to the ’700 patent. Thus, the Petition does not establish by a preponderance of the evidence that claims 5, 15, and 25 are obvious over the combination of Barsoum and ATSC327.” slip op. at 22
