  PTAB · Apr 11, 2022 · IPR2021-00080 · APJ Patrick R Scanlon · IPR · Final written decision

  Claims 1–9 were not shown unpatentable because Metzger lacked the claimed fluid passage, and Wu was not prior art based on the claims’ earlier reduction to practice.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Relying on the testimony of Mr. Kuchel, Petitioner submits that a person of ordinary skill in the art “would have either (i) a bachelor’s degree in mechanical engineering, or an equivalent field, or (ii) would have an associate degree in mechanical engineering, or an equivalent field, and two years of practical experience in inflatable product design.” Pet. 16 (citing Ex. 1002 ¶ 26). In the Decision on Institution, we adopted Petitioner’s proposed level of ordinary skill in the art, stating it was “consistent with the evidence of record, including the asserted prior art.” Dec. Inst. 9. In its Response, Patent Owner makes arguments that rely on Petitioner’s proposed level of ordinary skill in the art, but does not dispute Petitioner’s definition. See PO Resp. 35, 39–53 (citing Ex. 2014 ¶ 66). Based on our review of the complete record, we continue to apply the level of ordinary skill in the art adopted in the Decision on Institution.” slip op. at 10

    “Petitioner proposes claim constructions for the terms “substantially below” and “substantially inwardly” recited in claims 1 and 6. Pet. 40–41. In the Decision on Institution, we determined that it was not necessary to construe the terms at that stage of the proceeding. Dec. Inst. 9–10 (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017)). Patent Owner contends “the claim terms ‘substantially below’ and ‘substantially inwardly’ are sufficiently clear on their face to preclude any need for claim construction,” but proposes claim constructions that differ somewhat from Petitioner’s proposed constructions in the event the Board determines that these terms require claim construction. PO Resp. 13, 15–16. Patent Owner also proposes a claim construction for the term “upper tubular periphery” recited in claims 1 and 6 that Petitioner opposes. Id. at 17–19; Pet. Reply 7–10. Only terms that are in controversy need to be construed, and then only to the extent necessary to resolve the controversy. Nidec, 868 F.3d at 1017. Because the outcome of our decision does not depend on either parties’ construction of the terms “substantially below,” “substantially inwardly,” or “upper tubular periphery,” we need not construe these terms to resolve the issues in dispute in this proceeding.” slip op. at 11

    “We agree with Patent Owner that Metzger’s gaps define fluid passages located between adjacent side support beams 25 (i.e., “internal walls”) and are not formed in any of the side support beams. We are not directed to any written description in Metzger indicating that the gaps are formed in a side support beam.7 Instead, Figures 5 and 6 of Metzger depict the gaps as being defined between four distinct side support beams 25. Furthermore, as Patent Owner points out, Mr. Kuchel appears to agree that there are no passages formed through the side support beams 25 of Figures 5 and 6. Ex. 2003, 107:12–108:9, 108:17–108:21. For these reasons, we determine that Metzger’s gaps are not formed through an internal wall, as required by claim 1. In the Reply, Petitioner asserts that, even if Metzger discloses four discrete, spaced-apart beams or walls, “the gaps or slices between walls are apertures in a structure through which air can pass.” Pet. Reply 15 (emphasis added). This argument is not persuasive because claim 1 recites that the fluid passage is formed through the internal wall (which Petitioner asserts is met by Metzger’s side support beam 25), not just any structure. Petitioner’s general assertion that air passes through “a structure” fails to establish that the gaps are formed in a side support beam.” slip op. at 16

    “Specifically, Petitioner argues that one of ordinary skill in the art would have understood from Metzger “that an air passage would be necessary to bypass the side support beam 25 and inflate the upper tubular periphery for the air mattress to function as intended.” Id. (citing Ex. 1002 ¶ 200). According to Petitioner, because Metzger discloses only a single air inlet valve, an ordinarily skilled artisan would have understood that providing openings, or fluid passages, through the side support beam 25, in lieu of or in addition to the gaps between the side support beam 25, would have been a simple solution to adequately inflate the peripheral frame of the mattress defined by the side support beam(s) 25. Id. at 74–75 (citing Ex. 1002 ¶ 200). Petitioner thus presents two alternate theories for modifying Metzger: (1) providing fluid passages in at least one side support beam 25 in addition to the gaps, and (2) providing fluid passages in lieu of the gaps. In support of the first theory, Petitioner only argues that providing fluid passages in the side support beams, in addition to the gaps between the ends of the side support beams, would have allowed the peripheral frame to inflate more freely. Id. at 75 (citing Ex. 1002 ¶ 201). In its Response, Patent Owner contends that “Petitioner is just wrong.” PO Resp. 45 (citing Ex. 2001 ¶¶ 146–149). Dr. Letton testifies that pumps used to inflate air mattresses are low flow and low pressure and generally inflate an air mattress to a maximum pressure of around 1 psi. Ex. 2001 ¶ 147. Dr. Letton further testifies that, with Metzger’s design, the” slip op. at 28
