      “disorder symptoms” require a “quantitative” calculation or use of an algorithm, we also disagree. See PO Resp. 14–16. First, nothing in the language of the claims themselves describes or requires a “quantitative” calculation or an algorithm. See generally Ex. 1001, 23:6–26:59. To be sure, the ’029 patent discloses embodiments that use known algorithms to “quantify the level of severity of the subject’s sleeping disorder or symptoms.” See, e.g., id. at 20:16–19. But the Specification does not require an algorithm. The Specification also indicates that quantification is merely “preferable” (i.e., not required), and is merely one embodiment. See, e.g., id. at 19:8–12 (“The signals from the one or more sensors used in various embodiments of the present invention are preferably analyzed using a processor and software that can quantitatively estimate or determine the severity of the subject’s sleeping disorder or symptoms.”) (emphasis added), 4:51–59 (“Finally, in still another embodiment, the present invention includes a sleeping disorder treatment system comprising a device for diagnosing and creating a quantitative output of a level of severity of a subject’s sleeping disorder or symptoms . . . .”) (emphasis added); see also Reply 5–6 (citing Ex. 1001, 4:3–59 and 19:8–12 and stating that the ’029 patent lists “numerous embodiments where only one of seven include a quantitative assessment”). Elsewhere, the Specification more generally states that signals from sensors are “analyzed to determine the level of severity of the symptoms,” without specifying that such analysis must be “quantitative” or performed by an algorithm. See Ex. 1001, 3:41–44. In view of these disclosures, Patent Owner does not persuade us to adopt its narrowing claim construction. Indeed, our reviewing court has “repeatedly warned against confining the claims” to specific embodiments disclosed in the Specification. Phillips, 415 F.3d at 1323. Patent Owner’s reliance on a prior Board decision in PGR2024- 00012, which related to the parent of the ’029 patent, is unavailing. See PO Resp. 15–16. We agree with Petitioner that in the cited case, “[t]he Board made no findings about the meaning of the term calculating ‘the data of a severity of the sleep disorder symptoms of the subject’ for claim construction.” Reply 8. Indeed, neither party offered any claim construction, and the Board determined that no claim construction was necessary for purposes of that decision. See ResMed Corp., PGR2024- 00012, Paper 7 at 8. The page of the decision Patent Owner cites addresses written description support in the specification for the claims challenged in that PGR, not claim construction. See id. at 16. In any event, the cited decision is a decision on institution. The Board’s statements there are, by nature, preliminary findings and conclusions based on a preliminary record, and are not binding here. For at least the above reasons, Patent Owner does not persuade us to adopt its narrowing claim construction and we find that the term “data of a severity” does not need construction because the words of the term are clear on their face.” slip op. at 31

      “skilled artisan would have incorporated only portions of Mumford’s algorithm into Truitt’s PAP (i.e., only those portions related to “the detection of sleep disordered events” and not the portions of the algorithm related to “determin[ing] sleep stage”) comes too late because this argument was not in the Petition. See, e.g., Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1286–87 (Fed. Cir. 2017) (rejecting petitioner’s “attempts to cure the petition’s deficiencies in its subsequent briefing to the Board”). The Petition does not discuss modifying Mumford’s sleep efficacy algorithm before incorporating it into Truitt’s PAP device or incorporating only certain features of the algorithm. Indeed, the Petition and Dr. Kirkness rely on Mumford’s ability to detect sleep arousals when mapping Mumford to the claimed “data of a severity” and “index.” See Pet. 69–70; Ex. 1003 (Kirkness Decl.) ¶¶ 323–325. Mumford discloses that the mask electrodes detect arousals. See Ex. 1009 (Mumford) 2:4–10, 11:39–48. The same lack of disclosure plagues Petitioner’s belated Reply argument that Truitt’s ports 74 and 76 can incorporate electric sensing elements that would have functioned similar to Mumford’s electrodes. See Reply 22. The Petition did not mention ports 74 and 76 or otherwise suggest that a skilled artisan would have added functionality similar to Mumford’s electrodes to Truitt’s PAP, and we find that it is too late on Reply for Petitioner to posit this modification.” slip op. at 40

      “significant than the intrinsic record in determining ‘the legally operative meaning of claim language.’” Phillips v. AWH Corp., 415 F.3d 1303, 1317 (Fed. Cir. 2005). This is especially applicable to Dr. Jafari’s opinions. His declaration was not prepared for this proceeding and thus Dr. Jafari was not subject to cross examination in this proceeding. See Reply 6 n.3. Moreover, Dr. Jafari was not opining on claim construction; rather, he was addressing the alleged indefiniteness. See Ex. 2020 (Jafari Decl.) 12 (heading addressing definiteness), ¶¶ 41–42, 46. Additionally, paragraphs 41–42 of Dr. Jafari’s declaration discuss claim terms phrases in a different patent (US 11,375,921), which explicitly include the terms “quantified” and “quantitative.” See Reply 6–7; Ex. 2020 (Jafari Decl.) ¶ 34. For at least these reasons, Patent Owner has not persuaded us that Dr. Jafari’s testimony is applicable here. Further, regarding the portion of Patent Owner’s proposed construction reciting “the degree of deviation from the baseline characteristics of a patient without sleep disorder symptoms,” Dr. Borkholder does not do his own analysis, but instead simply states that he “agree[s] with the litigation claim construction opinions of Dr. Jafari.” Ex. 2019 (Borkholder Decl.) ¶ 53. This is insufficient, and thus we do not credit Dr. Borkholder’s testimony regarding claim construction. We instead credit Dr. Kirkness’s statement that “[s]everity data is frequently calculated as the deviation from baseline characteristics of the patient himself, not a generic person ‘without sleep disorder symptoms.’” Ex. 1071 (Kirkness Reply Decl.) ¶ 13; Reply 9. As Dr. Kirkness explains, and Patent Owner does not dispute (see generally Sur-reply), “[t]he ‘baseline characteristics of a [generic] patient without sleep disorder symptoms’ would be irrelevant to any particular patient with their own unique breathing patterns and sleep disorder symptoms.” Ex. 1071 (Kirkness Reply Decl.) ¶ 13 (second alteration in original). For at least these reasons, we reject Patent Owner’s proposed claim construction.” slip op. at 30

    • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

      “May” expresses a possibility. The Specification reflects this interpretation of “may” when it states that “[i]n one embodiment, the organic material is not lyotropic. Thus, the organic material may not be a phospholipid.” Ex. 1001, 8:27–28 (emphasis added). One of ordinary skill would understand from this that the organic material “may not be” a phospholipid if the organic material is not lyotropic. It follows that if the organic material is lyotropic, then the organic material may be a phospholipid. Reading the statement “[t]he organic material may not be . . . a phospholipid” (id. at 8:59–63) in light of the earlier stated possibility that the organic material may be a phospholipid if the organic material is lyotropic, one of ordinary skill in the art would interpret “may not be” as excluding phospholipids under some conditions, not under all conditions. Taking the Specification’s discussion about phospholipids as exemplifying the permissive nature of the word “may,” we are unpersuaded that in stating that “[t]he organic material may not be [PMMA], a polyvinylidene difluoride-containing polymer, such as [PVDF] or PVDF- TrFE-CTFE, or a phospholipid, such as [DHPE]’” (Ex. 1001, 8:59–63), the specification “contains a clear and unmistakable disavowal of the compounds PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE” and “disclaims the listed compounds” from the “organic material” of the claims under all conditions, as Patent Owner argues. Prelim. Resp. 6–7. Moreover, the claims themselves limit the “organic material” only to the extent that it is “barocaloric cooling or heating agent” and can perform in the manner claimed. See Ex. 1001, claim 1, supra. As broadly worded, the claims do not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE per se from the group of organic materials employed by the claimed method. Adopting Patent Owner’s construction would impermissibly import a limitation (i.e., not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE) into the claims. For the reasons stated, at this stage of the proceeding, we agree with Petitioner’s broad construction of “organic material.” We do not adopt Patent Owner’s proposed construction whereby PMMA, PVDF, PVDF- TrFE-CTFE, and DHPE are excluded from the scope of the claim term “organic material.” The parties are invited to address this issue further during trial, if desired. slip op. at 11

      “invention. Graham, 383 U.S. at 17–18.

A person could also have qualified as a POSITA with some combination of more formal education (e.g., an M.D.) and less technical experience or less formal education and more technical or professional experience in the foregoing fields, and would have had further appreciation of various technical concepts in this field.

To the extent Mr. Culbert testifies otherwise, we do not find such testimony persuasive. Indeed, Olmos itself further supports Mr. Drewry’s testimony that a POSITA would have known how to modify dimensions to fit specific needs and make changes necessary to adapt features from one embodiment to fit another.

Sur-reply 7–9. This generic objection to the entire Reply fails to provide adequate notice regarding which of Petitioner’s theories and arguments Patent Owner contends are allegedly new and improper. See, e.g., Rembrandt Diagnostics, LP v. Alere, Inc., 76 F.4th 1376, 1383 (Fed.

      “improperly incorporates-by-reference 12 pages of expert testimony via a single sentence.” PO Sur-reply 16 n.2 (citing Pet. Reply 17, which in turn cites Ex. 1026 (Hatch Decl.) ¶¶ 49–66). We find that many of the paragraphs within the cited range (i.e., Hatch Declaration paragraphs 49–66) appear to have a tenuous connection to the proposition for which Petitioner cites these paragraphs. See Pet. Reply 17. That said, we find that paragraphs 53–55 directly relate to Petitioner’s proposition in the Reply, i.e., that “Petitioner’s experts explain why a [person of ordinary skill in the art] would rely on a cross-sectional view over a perspective view for making the determination in question, because only the cross-sections provide the needed side view directly orthogonal to the positions of the yellow expansion portion and the end of the dovetail.” Id. Accordingly, we find that paragraphs 53–55—the only paragraphs we cite from Petitioner’s range in reaching our conclusion—are not improperly incorporated by reference into Petitioner’s Reply.” slip op. at 66

      “provide Petitioner an opportunity to respond under the new construction, and decline to strike Petitioner’s relevant argument and evidence. Cf. Axonics, 75 F.4th at 1383 (“[W]hen the Board adopts a new claim construction following institution, an IPR petitioner must have adequate notice and an opportunity to respond under the new construction.”). Like in Axonics, in its new arguments on Reply, Petitioner here relies on the same embodiment from the same prior art reference that it relies on in the Petition to support the same legal argument, i.e., that Olmos’s Figure 16 embodiment discloses the “complementary with one another” limitation of challenged claims 10– 14. See Axonics, 75 F.4th at 1384; see also Apple Inc. v. Andrea Elecs. Corp., 949 F.3d 697, 706 (Fed. Cir. 2020) (permitting petitioner to elaborate in reply on an unpatentability theory presented in the petition). Moreover, we permitted Patent Owner to file (and it indeed did file) a sur-reply brief and expert declaration that addressed Petitioner’s new obviousness theories. Accordingly, both parties had adequate notice of our preliminary construction and an opportunity to respond under that new construction. For these reasons, we deny Patent Owner’s motion to strike.” slip op. at 124

      “from the expansion portion. We agree with Patent Owner that the wording of this limitation as a whole requires that the “extension necessarily must protrude beyond a longitudinal end of the expansion portion.” Id. at 11. We also agree with Patent Owner that “[u]nder Petitioner’s tenuous theory, an extension in any direction except 90 or 180 degrees would satisfy the claim language since any such direction has a so-called ‘longitudinal component.’” Id. at 13. For these reasons, we disagree with Petitioner’s argument that the purported “longitudinal component” of Chung’s extension satisfies limitation 1[h].” slip op. at 55

      “would have been motivated to add an extension to the Figure 16 embodiment because “an integrally-formed extension advantageously requires fewer parts, which facilitates both manufacturing and use.” Pet. 118. We agree with Patent Owner that this argument is unavailing. PO Resp. 50. Petitioner’s combination entails adding an extension (from Figure 8) to an embodiment lacking one (Figure 16). We agree with Patent Owner that adding a new component (whether separately or integrally) can in some instances complicate manufacturing/assembly and increase costs. See id. (citing Ex. 2013 (Culbert Decl.) ¶ 115). Petitioner has not sufficiently demonstrated that the proposed combination in this instance would reduce complexity or facilitate the manufacturing process. Accordingly, we do not rely on this argument offered by Petitioner.” slip op. at 106

      “According to the Specification, “the present invention . . . relates to a multimeric chromatography ligand (also denoted a ‘multimer’) comprised of at least two Domain C units, or a functional fragments or variants thereof.” Ex. 1001, 7:27–30. The Specification additionally recites that a multimer containing only domain C units can, however, include linkers. Id. 7:39–41. In addition, the Specification describes that “the multimer comprises one or more additional units, which are different from Domain C.” Id. 7: 44–45. Based on these disclosures in the Specification, a multimer is composed of at least two or more monomers. Because Petitioner’s construction is consistent with the ’142 patent’s express construction of the term, and because Patent Owner agrees with Petitioner’s construction, we apply it here.” slip op. at 14

      “knowledge that any one of the five SPA IgG binding domains are known to bind IgG and can function as a ligand for the purification of antibodies. Linhult and Abrahmsén both expressly suggest that the glycine codon at position 29 can be mutated for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Ex. 1004, 2; Ex. 1005, 2:32–37. Here, the SPA IgG binding domains comprise a short list of 5 members: E, D, A, B, or C. Of these 5 members, the glycine at position 29 in domain B has already been mutated to an alanine to create a domain Z which has been shown to retain IgG binding activity. Ex. 1004, 6 (Fig. 3). Figure 1A of Linhult is reproduced below. Linhult’s Figure 1A, reproduced above, shows the amino acid alignments of the Z, Z(F30A) and the five homologous domains (E, D, A, B, and C). The three boxes show the α-helices. Ex. 1004, 2; Ex. 1005, Fig. 2. Here, Linhult and Abrahmsén show that the IgG binding domains of SPA – E, D, A, B, and C share many structural similarities. See Ex. 1004, 2 (Fig. 1(a) (reproduced above)); Ex. 1005, 3:25–35. As discussed in our Institution Decision (Dec. 30–31), there are a finite number—five (5)—SPA IgG binding domains and each possesses the dipeptide sequence Asp-Gly known to a be a target for alkaline protein degradation. Therefore, the solution of mutating the glycine at position 29 for an alanine to remove the alkaline sensitive sequence is not a product of innovation, but of ordinary skill and common sense. See Wm. Wrigley Jr. Co. v. Cadbury Adams USA LLC, 683 F.3d 1356, 1364-65 (Fed. Cir. 2012) (quoting KSR, 550 U.S. at 421). It is well established that” slip op. at 37

      “Here, the teachings of Linhult, Abrahmsén, and Hober suggest mutating the glycine at position 29 for an alanine in any one of the IgG binding domains of E, D, A, B, or C of SPA in order to avoid protein degradation. Ex. 1004, 2; Ex. 1005, 5:4–9. We, therefore, agree with Petitioner that the art expressly suggests that the glycine codon can be mutated for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Pet. 23 (citing Ex. 1002 ¶¶ 99–111). Attaching any one of SPA mutated IgG binding domains E D A B or C to a matrix using “known ligand-construction methods to yield a predictable result[] (e.g., the claimed affinity chromatography matrix)” would have been obvious. Pet. 25 (citing Ex. 1002 ¶ 130). As the Federal Circuit has explained, “[w]here a skilled artisan merely pursues ‘known options’ from ‘a finite number of identified, predictable solutions,’ the resulting invention is obvious under Section 103.” In re Cyclobenzaprine Hydrochloride Extended-Release Capsule Patent Litig., 676 F.3d 1063, 1070 (Fed. Cir. 2012) (quoting KSR, 550 U.S. at 421). Accordingly, we agree with Petitioner that the combination of Linhult Abrahmsén, and Hober expressly suggests mutating the glycine codon for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Pet. 23 (citing Ex. 1002 ¶¶ 99–111). We also agree that the cited art teaches using these mutant SPA domains in column chromatography for the isolation of antibodies.” slip op. at 36
