Before STOLL, SCHALL, and CUNNINGHAM, Circuit Judges. CUNNINGHAM, Circuit Judge. I. BOARD DECISION The Patent Trial and Appeal Board issued a final writ- ten decision in an inter partes review determining that American National Manufacturing, Inc. (“ANM”) failed to demonstrate that claims 2, 4, 6, 12, 20, 22, and 24 of U.S. Patent No. 5,904,172 (“the ’172 patent”) are unpatentable but succeeded in demonstrating that claim 16 is unpatent- able as anticipated under 35 U.S.C. § 102(b). Am. Nat’l Mfg., Inc. v. Sleep No. Corp., No. IPR2019-00514, 2020 WL 4492370 (P.T.A.B. Aug. 4, 2020) (“Final Written Decision”). ANM appealed and the patent owner, Sleep Number Cor- poration (“SNC”), cross-appealed. We have jurisdiction un- der 28 U.S.C. § 1295(a)(4)(A). For the reasons below, we affirm. II. DISCUSSION After careful consideration, we are unpersuaded by ANM’s claim construction arguments. The Board did not Case: 21-1030 Document: 70 Page: 3 Filed: 07/25/2022

AMERICAN NATIONAL v. SLEEP NUMBER CORPORATION 3

err by construing “substantially fluidly sealed” to mean “largely but not wholly sealed.” Final Written Decision, 2020 WL 4492370, at *12. We agree with the Board that the constructions proposed by the parties introduced limi- tations—“deliver[ing] compressed air when operating” and “allow[ing] for monitoring the pressure in the bladder via the pressure in the enclosure,” respectively—that are un- supported by the intrinsic record. Id. at *11; see J.A. 64, 72 (’172 patent Abstract, col. 2 ll. 64–66). We also reject ANM’s argument that the Board’s construction of “guides” as “structures that position a component, prior to fas- tening, by directing the component into place,” (Final Writ- ten Decision, 2020 WL 4492370, at *13), and “stops” as “structures that position a component, prior to fastening, by arresting travel into the enclosure,” (id.), improperly in- troduced a temporal limitation or enforced an “order of steps.” Appellant’s Br. 3, 65–67. The Board’s construction appropriately distinguishes “guides and stops” from com- ponents used for fastening, which is consistent with the specification and the patentee’s representations to the Pa- tent Office during reexamination. J.A. 74 (’172 patent col. 6 ll. 39–45), 264–65. Further, the Board’s patentability determinations are supported by substantial evidence, and we reject ANM and SNC’s arguments to the contrary. See Appellant’s Br. 48–56, 69–73; Cross-Appellant’s Br. 62–65. ANM argues the Board erred by concluding Shafer’s 1 “air distribution unit” is not “substantially fluidly sealed” because the ’172 patent discusses using the same kind of “unsealed” pump as in Shafer. Appellant’s Br. 48, 52. Even accepting that the ’172 patent can use the same pump, it also teaches the use of a “substantially fluidly sealed” air chamber, (col. 2 ll. 64–66), and changes to the valves and ports depending

on whether the pump is or is not sealed, (col. 4 ll. 45–50, col. 7 ll. 32–62). J.A. 72–73, 75. ANM’s arguments focus on the ’172 patent and do not adequately explain what seal- ing exists within Shafer to challenge the Board’s finding that “Shafer is silent as to any seal of housing 300 of air distribution unit 206.” Appellant’s Br. 48–56; Final Writ- ten Decision, 2020 WL 4492370, at *15. Thus, ANM does not adequately explain how the Board’s conclusions as to Shafer are not supported by substantial evidence. As to Vrzalik, 2 ANM argues “supports 142” and the “interior sur- face” of the air box act as “guides and stops,” respectively. Appellant’s Br. 72. After reviewing Vrzalik’s limited dis- cussion of “supports 142”—J.A. 1204–05 (Vrzalik col. 8 ll. 33–38, col. 10 ll. 9–15)—a reasonable fact finder could have arrived at the Board’s conclusion that Vrzalik fails to meet this limitation. See In re Gartside, 203 F.3d 1305, 1312 (Fed. Cir. 2000); Final Written Decision, 2020 WL 4492370, at *18 (“Vrzalik is silent regarding supports 142 and the interior of the air box 124 positioning motor 138 and plug 140, respectively.”). Similarly, we reject SNC’s argument that Vrzalik fails to disclose a “substantially flu- idly sealed air chamber,” (Cross-Appellant’s Br. 62–65), be- cause Vrzalik teaches its air box is “airtight.” J.A. 1204 (Vrzalik col. 8 ll. 12–14); see Final Written Decision, 2020 WL 4492370, at *16–17. Finally, we decline to reach SNC’s argument that the Board erred in construing “pressure monitor means . . . for monitoring” in claims 12 and 16. Cross-Appellant’s Br. 65–66. SNC concedes it “did not argue below for pa- tentability of claim 16” based on its own construction and that it is the “prevailing party” for claim 12. Id. at 66. Thus, review of this issue is not proper on appeal. See SkyHawke Techs., LLC v. Deca Int’l Corp., 828 F.3d 1373, 1375–76 (Fed. Cir. 2016) (employing prudential rule

declining review for “prevailing party in a lower tribunal” despite concern district court would “rely on the Board’s claim construction”). The preclusive effect, if any, of the Board’s construction would need to be decided in a subse- quent action. In re Katz Interactive Call Processing Pat. Litig., 639 F.3d 1303, 1310 n.5 (Fed. Cir. 2011) (“[T]he pre- cise effect of the judgments in this case will necessarily have to be decided in any such later actions that may be brought.”); see also Apple Inc. v. Voip-Pal.com, Inc., 976 F.3d 1316, 1322 (Fed. Cir. 2020). We have considered the parties’ other arguments and find them unpersuasive. For the above reasons, we affirm. AFFIRMED COSTS
