“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. In fact, neither does Patent Owner’s witness, Mr. Leinsing, who states that his “opinions would not change under either definition.” Ex. 2011 ¶ 40. Thus, at this stage, we accept and use Petitioner’s proposed definition of the ordinarily skilled artisan, which, unlike Patent Owner’s, does not implicate reliance on the knowledge of people other than the individual ordinarily skilled artisan. Petitioner’s definition appears to comport with the level of skill in the art reflected in the prior art of record and the ’992 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (“the prior art itself [may] reflect[] an appropriate level” of the ordinary level of skill in the art) (quoting Litton Indus. Prods., Inc. v. Solid State Sys.

“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

Patent Owner concludes that “the Petition fails to adequately map the references to the claim elements with particularity.” Id. We disagree. Using claims 1 and 10 as an example, Petitioner asserts: Claim 10 recites a “system for automatically processing 3D images” that is substantively identical to the “method for automatically processing 3D images” recited in claim 1, addressed above. Whereas claim 1 (the method claim) recites a series of steps, each performed “by a processor,” claim 10 (the system claim) recites a “processor” with stored instructions that perform the same steps recited in claim 1. Similarly, dependent claims 11–14, 16, and 26 are substantively identical to dependent claims 2–5, 7, and 19. Pet. 41–42. Claims 1 and 10 contain similar elements and limitations.

“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.

“At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code.

“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.

“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).
