      “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.

      “The basis of disagreement boils down to an evaluation of a skilled artisan’s experience. In that respect, Petitioner urges that the artisan generally has “substantial experience in the structural design of flexible elements and plastic polymers,” whereas Patent Owner characterizes the experience as directed to “biomechanical systems.” The ’079 patent is clearly directed to matters of shoe construction, and takes note, for instance, of the desirability of “cushioning and biomechanically supporting the foot.” Ex. 1001, 1:27–29. It is also apparent that an overarching focus of the ’079 patent is concern with “balance” and “support” of a “foot against misorientations such as pronation and supination (i.e. a tilting movement of the forefoot part to the medial and the lateral side, respectively).” Id. at 2:34–39. Such concerns, in our view, go beyond general experience in the design of flexible elements and plastic polymers. In that regard, we credit the testimony of Patent Owner’s declarant, Dr. Hinrichs, that a person of ordinary skill in the art would have experience with biomechanical systems, such as shoes. See Ex. 2001 ¶¶ 14–15. We have considered the respective opinions of the parties when it comes to the level of ordinary skill in the art. In reaching our decision as to the merits of this proceeding, for the reasons discussed above, we are persuaded by Patent Owner’s evidence as to the ordinary skill of an artisan.” slip op. at 12

Yet, in our view, neither Mr. Ganaja nor Petitioner explains adequately how the teachings of the prior art would have led one down the path that they advocate. For instance, it is decidedly unclear from the record that any “longitudinal groove” as advanced in Petitioner’s annotated illustrations of Luthi ’202’s Figure 17 reproduced herein exists in the configuration proposed by Petitioner. Although Petitioner and Mr. Ganaja postulate that it does exist, Luthi ’202’s teachings are less than determinative in that respect.

      “We observe that Patent Owner relies on content of the ’079 patent at column 11, lines 31–34 to support the meaning of “leaf spring[s]” and “leaf spring element[s]” that it advances. That portion of the ’079 patent describes embodiments of the invention appearing in Figures 19 to 25. Referencing particular leaf spring elements 22 and 23 of those embodiments, the ’079 patent states that “[t]ypically the restoring force exerts a force that has a component orthogonal to the sole plate (e.g., for cushioning) and a component parallel to the sole in the rearward direction (e.g., for acceleration).” Ex. 1001, 11:31–34. While that language mirrors the meaning of “leaf spring[s]” and “leaf spring element[s]” proposed by Patent Owner, we discern that the noted clause also begins with the term “[t]ypically.” That leaf spring elements may “typically” include a component parallel to the sole in the rearward direction does not lend itself to the conclusion that a “leaf spring” necessarily includes such a component. Rather, it conveys the opposite. In that respect, the plain understanding of the pertinent content of the ’079 patent is that, while, perhaps, not typical, the ’079 patent contemplates other component arrangements, logically including those in which the parallel component is not in the rearward direction.” slip op. at 7

Moreover, even if such groove does exist, neither Petitioner nor Mr. Ganaja adequately explains why the presence of such groove would create at least two leaf springs or leaf spring elements that are “integrally joined to form a single end not directly connected to the sole plate,” as required by all the claims involved in this proceeding. We agree with, and credit, the testimony of Dr. Hinrichs that “Luthi ’202 consistently discloses that the strut elements run the entire width of the shoe.” Ex. 2001 ¶ 32 (citing Ex. 1005, 3:47–50 (“the strut elements 22 extend substantially from the medial edge of the lateral edge of lower plate 26 . . .”)). In extending the entire width of the shoe, strut elements 22 (and 222) are more appropriately viewed as a single element (e.g., a spring element) rather than multiple spring elements that come together integrally. Petitioner and Mr. Ganaja also inadequately explain why combination of Luthi ’202’s teachings with those of either Luthi ’800 or Chan would result in the above-noted “central cavity” as a part of the directional element of Luthi ’202’s Figure 17. Although Luthi ’800 and Chan may show spaces or cavities in components of their shoes, there appear substantial differences in the designs of those shoes, and in particular the cushioning aspects, as compared with Luthi ’202’s Figure 17. We credit Dr. Hinrichs’s and Dr. Luthi’s testimony that the presence of such a cavity as shown in Luthi ’800 and Chan would prove detrimental to the medial-lateral stability of Luthi ’202’s shoe, and specifically the directional element of such a shoe that is depicted in Luthi ’202’s Figure 17. See Ex. 2001 ¶ 42; Ex. 2005 ¶¶ 11–13. To that end, we also find inadequate Petitioner’s general position that combining the teachings of Luthi ’202, Luthi ’800, and Chan would result simply in a “combination of familiar elements according to known methods that would yield predictable results,” and “well within the knowledge and skill of persons of ordinary skill in the art . . .” Pet. 35. We are not persuaded that any such combination would yield the “predictable results” advanced by Petitioner, or that “well within the knowledge and skill” of an artisan cited by Petitioner constitutes rational underpinning to support an obviousness conclusion. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (An assertion of unpatentability based on “obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”)” slip op. at 22

Rather, it conveys the opposite. In that respect, the plain understanding of the pertinent content of the ’285 patent is that, while, perhaps, not typical, the ’285 patent contemplates other component arrangements, logically including those in which the parallel component is not in the rearward direction. Indeed, our above-noted understanding is also consistent with other embodiments described in the ’285 patent. For instance, embodiments depicted in Figures 13–16 show elements 23 extending in a forward direction with respect to the sole. The elements 23 of those figures are described as “leaf spring elements.” Id. at 10:15–50. Moreover, the ‘285 patent makes explicit that those leaf spring elements “are either forwardly or rearwardly directed.” Id. at 10:49–50. Patent Owner’s position that the claimed “leaf springs” or “leaf spring elements” require a parallel component extending in the rearward direction is inconsistent with these particular figures and the accompanying description in the ’285 patent. To that end, Patent Owner does not explain persuasively why the meaning of the term “leaf spring” encompasses only a parallel component in the rearward direction, yet the ’285 patent clearly provides that leaf springs may also have components that extend in the forward direction. Accordingly, for the foregoing reasons, we again conclude that “leaf spring[s]” and “leaf spring element[s]” mean “a flexible member that deflects and provides a restoring force with an orthogonal and a parallel component in response to a load applied to the sole.” We discern that it is unnecessary to construe expressly any other claim term of the ’285 patent.
