      “understanding of a person of ordinary skill in the art at the time the invention was made.10 See Graham, 383 U.S. at 17–18. The parties agree that a person of ordinary skill in the art (sometimes referred to herein as “POSITA”) would have had: at least a bachelor’s degree in mechanical engineering, electrical engineering, computer science, biomedical engineering, or a similar technical field, with at least two years of relevant product design experience working with diagnostic sensor systems and network data systems, such as networked PAP machines. Additional experience could substitute for less education, and additional education could likewise substitute for less experience. Pet. 3–4 (citing Ex. 1003 (Kirkness Decl.) ¶ 44); PO Resp. 4. 9 Patent Owner does not assert any objective indicia of nonobviousness. See generally PO Resp. 10 For purposes of this Decision, we apply a priority date of November 4, 2005. See supra n.4. Because the proposed level of ordinary skill in the art is consistent with the cited prior art and is undisputed on this record, we adopt it for purposes of this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (indicating that the prior art itself may reflect an appropriate skill level).” slip op. at 9

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

      “Patent Owner does not persuade us to construe the term as “a value [or calculated value] that indicates how dire a patient’s symptoms are.” Patent Owner points to nothing in the intrinsic record that purportedly supports this construction, and we agree with Petitioner that “the patent specification’s disclosures regarding determining a level of symptom severity are broad, establishing that it can generally be derived from any sensor data and/or breathing events.” Pet. Reply 3–4; see also Ex. 1001, 3:44–46 (“Signals from the[] sensors are then analyzed to determine the level of severity of the symptoms of the subject’s sleep disorder.”). Patent Owner relies only on expert declarations to support its construction. But as indicated by the Federal Circuit, extrinsic evidence is “less 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 here, where neither Dr. D’Ambrosio’s nor Dr. Schwartz’s declaration was prepared for this proceeding, and neither declarant was subject to cross examination on their opinions. Moreover, neither of the declarants was opining on claim construction; rather, they were addressing indefiniteness and/or written description issues. See Ex. 1058 at 7 (heading addressing definiteness); Ex. 2026 at 18 (heading addressing written description). Further, Dr. Schwartz appears to have been making an argument about certain patent claims (not the challenged ’333 patent) based on Patent Owner’s own statements made during prosecution of a separate patent application. See Ex. 2026 ¶ 47 (“[T]he similar term used in the ’284 patent claims (‘data of severity of sleep disorder symptoms’) does not find written description support in the specification by a disclosure of the same statistics disclosed in Wright, because CleveMed argued those statistics are not related to severity of sleep disorder symptoms.” (emphasis added)). Patent Owner has not persuaded us that Dr. Schwartz’s testimony has direct applicability to the claim term at issue here. Dr. Borkholder’s testimony is likewise unpersuasive. Aside from citing Dr. D’Ambrosio’s and Dr. Schwartz’s declarations, Dr. Borkholder cites Exhibits 2027 and 2016. These exhibits discuss indices such as AHI and RDI that are used to assess the severity of a patient’s symptoms, but Patent Owner has not adequately explained how they bear on construction of the claim term at issue here, which is not addressed in these exhibits. Ex. 2022 ¶¶ 32–33. Accordingly, we accord Dr. Borkholder’s claim construction opinions little weight, because they are unsupported by reference to objective, corroborating evidence of record. See, e.g., Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations . . . may render the testimony of little probative value in a validity determination.”); Xerox Corp. v. Bytemark, IPR2022-00624, Paper 9, 15 (PTAB 2023) (precedential) (explaining that declaration testimony that “is conclusory and unsupported” and which “adds little to the conclusory assertion for which it is offered to support . . . is entitled to little weight”).” slip op. at 23

      “We find that Petitioner has the better argument. Tidal volume refers to “the volume of air that is inspired or expired during a respiratory cycle.” Ex. 2028, 13–14; PO Resp. 10. “[H]ypopnea events are defined as a reduction of ≥50 % or 74 % in tidal volume from baseline and apnea events as absence of tidal volume for at least 10s.” Ex. 2028, 13–14 (emphasis omitted). Toge teaches that a control unit analyzes collected data (e.g., the flow rate) and calculates tidal volume. Ex. 1044 (Toge) ¶¶ 34–38. The calculated tidal volume is “a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy” because it represents, e.g., the “level of airway obstruction the patient experiences during the sleep apnea treatment using the PAP device.” Pet. 15. As Dr. Chatterjee explains: Toge discloses that tidal volume Fp is a quantified level of data because Toge discloses that Fp is monitored with respect to threshold values (id., [0051]) and because Fp is a function of Ft, Fa, and Fb, which are quantitative values. Toge discloses that tidal volume Fp is severity data because Toge discloses that tidal volume is indicative of whether the patient’s breathing warrants “emergency measures” (id., [0039]) and whether to “send an alert” in “an emergency where the patient’s breathing has drastically weakened” (id., [0055]). . . . . Because Toge discloses determining tidal volume (determine a quantified level of severity data) based on Ft, Fa, and Fb (id., [0035]), which corresponds to the subject’s condition (subject’s sleep apnea symptoms) while using the device (during the therapy) (id., [0036], [0037]), Toge discloses determin[ing] a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy. Ex. 1005 (Chatterjee Decl.) ¶¶ 122–125. Patent Owner’s attempt to dismiss tidal volume as a mere “breathing metric” is unavailing. First, Petitioner correctly “notes that in the paragraph PO cites to in Dr. Schwartz’s declaration, he indicates that breathing metrics are a level of severity data.” Pet. Reply 8 (citing Ex. 2026 ¶ 46 (“standard sleep disordered breathing metrics” [ ] were well validated indicators of the type and severity of sleep disordered breathing”)). Second, Dr. Kirkness explains that tidal volume represents the level of airway obstruction, e.g., apnea “is the most severe form of reduction in airflow [and] the absence of airflow results in quantified tidal volume of zero milliliters per breath.” Ex. 1003 (Kirkness Decl.) ¶¶ 157, 159; see also PO Resp. 10–11 (Patent Owner recognizing that an apnea is defined as absence of tidal volume for at least 10 seconds). The calculated tidal volume thus indicates severity because it is used to adjust the PAP system, e.g., in the case of decreasing tidal volume, a medical professional can change the airflow settings “to counter/treat the more severe level of airway obstruction observed from the decreasing tidal volume.” Ex. 1003 (Kirkness Decl.) ¶ 158; Pet. 15–16; Ex. 1044 (Toge) ¶ 39.” slip op. at 26

      “We agree with Patent Owner that Petitioner has not shown sufficiently that Squatch is a printed publication. As described above, Petitioner relies on Squatch as a “website excerpt” placed on its site at the relevant time, but has not produced a screen shot of the website to show that it ever existed. See Ex. 1059. Petitioner provides internal documents that purport to describe what would have been on Dr. Squatch’s website at the relevant time, but falls short of establishing what was on the website for the interested consumer to view.

In particular, Petitioner proposes that “drill guide” means “drill guide made from metal or metallic alloy without traditional plastic or acrylic,” and that “fixation base” means “fixation base made from metal, metallic alloy or other strong material without traditional plastic or acrylic.” Id.

According to Petitioner, its proposed constructions should be adopted “based on disclaimer of claim scope in the provisional application incorporated into the [’209] patent specification.” Id. at 14–24.

      “substitution of the word ‘enclose’ for the term ‘surround.’” Sur-reply 6. We noted in the Institution Decision that “construing the claim term ‘surround’ to mean ‘enclose’ does not further inform or clarify to a person of ordinary skill in the art what is encompassed by the claim limitation.” Dec. 15. We reach the same conclusion here on the full record and find no basis to rewrite the Challenged Claims to replace “surround” with “enclose.” To the extent Patent Owner can be understood to suggest that we import additional limitations into the claims based on the exemplary figures in the ’209 patent, we decline to do so. Regardless, given the recognition by the Parties that “surround” and “enclose” are synonymous, our determinations in this Decision would have been the same had we adopted Patent Owner’s proposed definition of “surround” to mean “enclose.” Further, with regard to the claim language “configured and dimensioned to surround at least a portion of the teeth of the patient,” Patent Owner proposes construing “a portion of the teeth” as “at least some teeth.” Resp. 9 (citing Ex. 2007 ¶ 44). Patent Owner, however, offers no sufficient explanation in its Response to explain how why a “portion of the teeth” means “at least some teeth.” The Specification does not provide an explicit definition of “a portion of the teeth” and does not suggest an intention to use a meaning of the term “a portion of the teeth” that is particular to the ’209 patent. To the extent Patent Owner can be understood to imply that we should import additional limitations into the Challenged Claims based on the exemplary figures in the ’209 patent, we decline to do so.

      “We have considered Patent Owner’s arguments but find, on this record, Petitioner to have the better position. In particular, we are persuaded that a POSA would have been motivated to add magnesium hydroxide to Lesniak’s compositions because Phinney teaches that: (i) zinc oxide has “low activity” as a “deodorant agent”; (ii) magnesium hydroxide is “an effective synergistic effects, hence motivating a POSA to add magnesium hydroxide to Lesniak’s zinc oxide deodorants. Ex. 1004, 1:13- 3:16, 5:61-67. Reply 10; see also PO Resp. 25–26 (arguing that a POSA would have found it obvious to add magnesium hydroxide to the composition of Lesniak because zinc oxide is not a particularly efficacious antimicrobial in deodorants when used alone, whereas magnesium hydroxide is an effective deodorant). We acknowledge that Phinney suggests mixing zinc oxide with water in order to convert zinc oxide to zinc hydroxide. See, e.g., Ex. 1004, 1:17– 19 (“It was also found that a mixture of the hydroxides of zinc and magnesium could provide long lasting protection against odour due to perspiration.”). The evidence of record, however, shows that both magnesium hydroxide and zinc oxide were known options for deodorant antimicrobials, and claim 1 does not require a minimal level of effectiveness such that the combination of magnesium hydroxide and zinc oxide would need to outperform any other combination including the mixture of zinc and magnesium hydroxides. See In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (“Our case law does not require that a particular combination must be the preferred, or the most desirable, combination[.]”). Here, we also credit the testimony of Dr. Michniak-Kohn that “POSA would understand that the water-based vs. anhydrous distinction is not relevant, as a POSA would understand that magnesium hydroxide would still function as an antimicrobial in anhydrous compositions such as those disclosed by Lesniak.” Ex. 1086 ¶ 9 (citing Ex. 1072, 1-2, 5 (disclosing deodorants without added water and with zinc oxide and/or magnesium hydroxide)).

See Ex. 2011 ¶ 109–110. Thus, the specific set of advantages and disadvantages for using baking soda in a deodorant was known to a person of skill in the art. On this record, the inclusion or exclusion of baking soda presents no unexpected result and the evidence of record establishes that it would have been an obvious matter of design choice within the skill of the art to balance the advantages and disadvantages associated therewith. See Medichem, S. A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed.

Specifically, claims 1 and 2 recite electrostatically attracting the particulate matter, holding the matter in place, and inactivating the matter.

This is done by varying the concentration of ingredients . . .[,] thereby adjusting the adhesion and cohesion of the thin film.” Pet. Reply 3 (quoting Ex. 1010, 17). Furthermore, as stated in our Institution Decision, along with that term, the claim language explains that the thin film is meant to stick to the skin or tissue and to hold the particulate matter in place. Inst. Dec. 9–10. The claim language also explains that the cohesion of the formulation is adjusted to provide adequate impermeability to the thin film. Thus, it is reasonable to consider the recited impermeability is a function of the cohesive properties of the thin film, and that such impermeability refers to a property of the thin film, i.e., inhibiting the penetration or passage of matter through it onto the skin or tissue at the application site.” slip op. at 10

In claim 1, a biological sample from the patient must be tested to determine if the cancer is MSI-H and, if so, the patient is treated with a therapeutically effective amount of pembrolizumab.

      “record, we are persuaded that the results recited in claim 1 would follow from the steps taught in the MSR, for the reasons and based on the evidence Petitioner cites above. For these same reasons, we are unpersuaded by Patent Owner’s argument that it was unknown whether the amount of pembrolizumab recited in claim 1 would be effective in producing an improved outcome compared to a reference patient without a tumor that was not MSI-H or dMMR, and Patent Owner does not dispute that the amount of pembrolizumab disclosed in the MSR (10 mg/kg every 14 days; see Ex. 1005, 4) is the same as the amount provided in the ’975 patent as being effective (10 mg/kg every 14 days; Ex. 1001, 8:48–52, 13:50–52). Regardless of the inventors’ intent in publishing the MSR as a Stage II clinical trial on the www.clinicaltrials.gov website, as discussed above, we determine that the MSR teaches selecting a patient with a metastatic MSI-H or dMMR tumor and administering an amount of pembrolizumab that would be effective. See, e.g., Ex. 1005, 4 (Arms and Interventions). The result of drug treatment inherently follows its administration. The MSR does not merely suggest that pembrolizumab may be useful in some unidentified subset of patients or suggest that some unidentified drug may be useful for MSI-H cancer patients. Instead, the MSR discloses selecting a patient with a condition recited in claim 1 and treating with the drug at the amount recited in claim 1. Contra Metabolite Labs. Inc. v. Lab. Corp. of Am. Holdings, 370 F.3d 1354, 1367 (Fed.

Patent Owner attempts to distinguish the size and apparent surety of the study in Montgomery from the MSR. PO Resp. 15. But because we find that the MSR teaches performing the steps recited in claim 1 for the purpose of determining and treating MSI-H cancer, we are persuaded that the MSR inherently discloses the results of selection of patients and administration of the drug treatment recited in those steps. See Bristol-Myers, 246 F.3d at 1376. Whether or not the MSR could have provided results or was sufficient for full regulatory approval does not change that the MSR teaches Patent Owner’s claimed steps. We have no reason to doubt that the disclosure in the MSR of the steps recited in claim 1 produces the efficacy element required in claim 1, whether or not this efficacy was disclosed in the MSR or was known when it was published.
