“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.

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.

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.

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.

- 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

“According to Petitioner, a person of ordinary skill in the relevant art (“POSA”) “would have had at least a bachelor’s degree in agronomy, agricultural sciences, or a related field and at least 3-5 years of experience in the application of pesticides, including experience conducting weed science research, such as field trials to determine herbicide efficacy and safety.” Pet. 25 (citing Ex. 1002 ¶ 10). Patent Owner responds that it does not challenge Petitioner’s definition of a POSA at this stage of the proceeding. Prelim. Resp. 15. Because Petitioner’s definition of a person of skill in the art appears commensurate with the level of skill reflected in the asserted art in this case, as well as the ’463 patent itself, we apply Petitioner’s proposed level of ordinary skill in the art to determine whether it is more likely than not that Petitioner would prevail with respect to at least one of the claims challenged in the Petition.

- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction needed
“When claim 1 is read in light of the Specification of the ’463 patent, we find that Petitioner’s construction is too expansive and not commensurate with the appropriate scope of claim 1 when the Specification of the ’463 patent is considered. As the Specification of the ’463 patent makes clear, indaziflam has been in use as an herbicide and is well-characterized. See Ex. 1001, 3:17–6:6. The Specification of the ’463 patent incorporates by reference U.S. Patent No. 8,114,991, which describes indaziflam, and the Specification of the ’463 patent also describes several commercially available herbicides incorporating indaziflam as their active ingredient. See id. at 3:22–27, 4:15–41. The Specification of the ’463 patent sets forth embodiments with specific ranges for the amount of indaziflam. See id. at 5:45–6:6. Finally, the Specification of the ’463 patent states: A person having ordinary skill in the art would understand how to adjust dosages and concentrations depending on whether the composition is to be applied to a desirable plant or seed, part or habitat thereof, or directly to a site in which no desirable plants are present or growing (e.g., a monoculture of unwanted annual grass).” slip op. at 11
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITANo construction needed
“We find that Petitioner’s expansive construction of the claim phrase “a composition comprising a cellulose biosynthesis inhibitor” to be inconsistent with the meaning of the transitional phrase “comprising” within the context of the claim as a whole and also inconsistent with the teachings set forth in the Specification of the ’463 patent. The transitional phrase “comprising” is inclusive or open-ended and should be read to not exclude additional, unrecited elements or method steps. See, e.g., Invitrogen Corp. v. Biocrest Mfg., L.P., 327 F.3d 1364, 1368 (Fed. Cir. 2003) (“The transition ‘comprising’ in a method claim indicates that the claim is open-ended and allows for additional steps.”); Genentech, Inc. v. Chiron Corp., 112 F.3d 495, 501 (Fed. Cir. 1997) (“Comprising” is a term of art used in claim language which means that the named elements are essential, but other elements may be added and still form a construct within the scope of the claim.”) (citing In re Baxter, 656 F.2d 679, 686 (CCPA 1981). Therefore, although the term “comprising” does not exclude additional steps or elements, that does not mean that any other step or element may or should be added, such as any other chemical, as Petitioner asserts. The Specification of the ’463 patent contemplates using indaziflam as the herbicidally active ingredient, but also contemplates the addition of other active ingredients in the composition. Ex. 1001, 5:59–65; 6:7–11. The Specification of the ’463 patent also contemplates the addition of other ingredients in the composition as well. Specifically, the Specification states: These formulations are produced in any desired or known manner, for example by mixing the active compounds with extenders, such as liquid solvents, pressurized liquefied gases and/or solid carriers, optionally with the use of surface-active agents, such as emulsifiers and/or dispersants and/or foam formers. Id. at 17:6–11. This and the remainder of the Specification does not suggest the expansive interpretation of the claim limitation argued by Petitioner. For example, the Specification explains that the point of the invention is to treat vegetation that is or will be consumed by livestock animals, and, more specifically, that such animals will provide food (e.g., milk or meat) for others (e.g., people or pets) further up the food chain. Id. at 2:31–35, 2:39– 59. Reason and the evidence of record support that such goals are not commensurate with co-applying any chemical in any amount to the same area.

“argument, Petitioner has not shown that such a disclaimer exists in the prosecution history. The purported disavowal of claim scope with respect to the plain meaning of a claim term must be unambiguous, clear, and unmistakable to one of ordinary skill in the art. Elbex Video, Ltd. v. Sensormatic Elecs. Corp., 508 F.3d 1366, 1371 (Fed. Cir. 2007) (citations omitted). Petitioner has not made such a showing. Rather, Petitioner points to language that was added to the claim during prosecution, namely, “performing arithmetic coding on a first bit of the binary data corresponding to each absolute value of the coefficients,” and concludes that this language requires coding a first bit separately from the remaining bits, using separate probability tables. Pet. Reply 10 (citing Ex. 1012, 656). We agree with Patent Owner, that the plain meaning of this claim language does not require coding a first bit separately from the remaining bits, using separate probability tables. Prelim. Resp. 57–58. Turning to the prosecution history, Petitioner does not explain how the applicant’s remarks to the Examiner in the prosecution history show a clear and unmistakable disavowal of claim scope. See Pet. Reply 9–10. Further, the applicant did not state to the Examiner that the claim requires coding a first bit separately from the remaining bits, using separate probability tables. See Ex. 1012, 662–664. On this limited record, it is not clear how the applicant’s arguments in the prosecution history persuasively show that the applicant made a clear and unmistakable disavowal of claim scope. Therefore, we construe the claim according to its plain and ordinary meaning, which does not require coding a first bit separately from the remaining bits using separate probability tables as alleged by Petitioner.” slip op. at 25
- Strike new argumentNew argument disregardedDecided for patent owner
“We agree with Patent Owner. Petitioner’s claim construction regarding prosecution history disclaimer does not address “unanticipated and incorrect statements” made by Patent Owner “regarding the law with respect to written description and the disclosure of the subject patent and priority applications, to which Petitioners need to respond.” Ex. 1041. Specifically, Petitioner does not allege an incorrect statement in Patent Owner’s contention that “Petitioner admits that JP029 discloses performing the encoding on all bits of binary data, including the ‘first bit’ of data.” Prelim. Resp. 55 (citing Pet. 29). Nor does Petitioner allege an incorrect statement in Patent Owner’s contention that “Petitioner’s expert opines – with no explanation or citation – that the claims require ‘separately arithmetically encoding/decoding a first bit of binary data using a separate probability table from the probability table (or tables) used to encode/decode the remaining bits of binary data.’ Nothing in the claims require this.” Id. at 57 (citing Ex. 1003 ¶ 52). Instead, Petitioner, for the first time in its Reply, proposes construing the claim beyond its plain and ordinary meaning in order to rebut Patent Owner’s contention that the plain and ordinary meaning of the claim does not require coding a first bit separately from the remaining bits, using separate probability tables. Petitioner has not explained how Patent Owner made an incorrect statement, nor has Petitioner explained why Patent Owner’s construction of the claim based on the claim’s plain and ordinary meaning was unanticipated. See Pet. 7 (“[T]he Petition does not present any controversy over claim meaning and the Board need not construe any terms.”); see id. at 8 (“Petitioner maintains that the Challenged Claims would have been obvious under any reasonable construction.”).
