    “Petitioner also focuses on Hanafusa’s teaching that all known methods can be used to make a rough surface low-profile, and Dobashi’s teaching that RSm can be used as an indicator for judgment of the surface, to support its contention that a POSITA would have been motivated to apply Dobashi’s RSm to further achieve Hanafusa’s purpose, without explaining how and why that would be the case. In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness and is rough when RSm is small.” Id. at 3:1–3, 6:27–29. Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66– 3:1.

    “Patent Owner’s proposal for the level of ordinary skill in the art differs from that of Petitioner, primarily because Patent Owner contends that such a person of ordinary skill would have a certain degree of experience relating specifically to skid steers, or similar machinery, and their hydraulic systems. See Prelim. Resp. 8–10 (citing Ex. 2001 ¶ 31). Insofar as we understand the significance of Patent Owner’s concerns about the differences between the parties’ proposals, these differences do not bear upon the issues addressed herein. Accordingly, for the purposes of the present Decision, we adopt Petitioner’s proposed definition of the relevant level of ordinary skill in the art.

    “We agree with Patent Owner. Petitioner argues that “Patent Owner made the deliberate choice to claim broadly,” eschewing “structural limitations that would have expressly or implicitly required the hydraulic of Element [1.4] to differ from the hydraulic of Element [1.5].” Reply 7. Further, Petitioner argues that “Patent Owner chose to generically recite ‘a hydraulic’ in each of Elements [1.4] and [1.5] without distinguishing labels, identifiers, or qualifiers.” Id. To the contrary, the two recited “hydraulic[s]” are distinguished by the language surrounding and modifying each instance in the method of claim 1. Indeed, the recitations of distinct operations performed by each “hydraulic,” in the claimed method, further support the understanding these are distinct and different structures. Additionally, as Patent Owner contends (see Prelim. Resp. 16), each instance of “hydraulic” is introduced with the indefinite article “a” — a signal that the two instances of “a hydraulic” do not refer to the same structure.

    “As Patent Owner argues, Petitioner’s proposed combination of Funk and Lewis “would interfere with the intended operation of the Funk control system to move the lift arms up and down in response to inter alia changes in the height signal.” Prelim. Resp. 20. This scenario is similar to that in Tec Air, 192 F.3d at 1356, which involved a claimed injection-molding technique that used screw-threaded adjustable plugs accessed from the inner, cavity-facing, side of the mold. The proposed combination included a prior art reference disclosing adjustment members accessed from the opposite, outer, side of the mold, and having a non-threaded smooth tip that extended through the mold and into the cavity. Id. at 1360. The Federal Circuit held that the prior art reference was properly determined to teach away from the claimed invention, because “no screw driver would be able to turn the smooth-headed screws from the cavity-side of the mold,” hence the proposed “combination would be inoperable for its intended purpose.” Id. Likewise, the proposed combination in the present matter teaches away from the subject matter of claim 1, because it would “immobilize [Funk’s] main arm,” and its associated hydraulic cylinder 18, “leaving just ‘one’ of Funk’s two adjustment mechanisms — blade tilt — available for grade control” (Pet. 10), thereby decreasing the system’s accuracy (see Ex. 2001 ¶¶ 113– 14) and negating the very technique that Funk relies upon to achieve its stated goal.

    “We now turn to the merits of Petitioner’s asserted Grounds of unpatentability. Analysis of Claims We focus our analysis on the term “release logic,” which appears in all the challenged claims. As we explained above, we determined that the term “release logic” along with its recited functions should be construed under Section 112 ¶ 6 to cover “corresponding structure, material, or acts described in the specification and equivalents thereof,” that perform the recited functions. Petitioner did not identify how the asserted prior art described those structures or their equivalents. Instead, as discussed above, Petitioner relied on Patent Owner’s preliminary construction in the District Court, which Patent Owner identified in wholly functional terms as a “specific sequence of actions.” Pet. 6 (citing Ex. 1010; Ex. 1002 ¶¶ 52–53); Prelim. CC Reply 1 (citing Ex. 1010, 5). Thus, Petitioner’s analysis fails to address how the prior art meets the limitations set forth in the claims as we have interpreted those claims. Accordingly, we find that Petitioner has failed to meet its burden to establish a reasonable likelihood that it would prevail with respect to at least one of the claims challenged in the petition. Thus we deny institution of an inter partes review. See Samsung Elecs. Am., Inc. v.

    “sophistication of the technology; and (5) educational level of active workers in the field.” Id. ¶ 30. Dr. Hull fails to state whether these factors were relied upon in forming his opinion, and if so, he also fails to state the underlying facts or data relating to these factors on which the opinion is based. There is no evidence to support why an “advanced degree” in mechanical engineering and five years of relevant experience is required. His opinion is supported only by his statement that he is “familiar with the technology at issue here and the state of the art at the time the application leading to the ’953 patent was filed.” Ex. 1002 ¶ 31. Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight. 37 C.F.R. § 42.65(a). Here, based on Dr. Hull’s extensive experience, we give his testimony some, but little, weight. Patent Owner states that “for purposes of this Preliminary Response only, VSD does not now dispute the definition of the POSITA as set forth by Dr. Hull.” Prelim. Resp. 7. We note that Patent Owner’s position is based on Dr. Hull’s full testimony, not the excerpt asserted by Petitioner. Accordingly, for purposes of this Decision, and based on the limited record before us, we determine, based on Dr. Hull’s testimony, the cited prior art, and Patent Owner’s qualified agreement with Dr. Hull’s testimony, that a person of ordinary skill in the relevant technology would have had an advanced degree in mechanical engineering or a related discipline and five years of experience in either ski binding design, manufacture, or testing; research concerning ski bindings and related equipment; or the development of standards concerning ski bindings or related equipment.

    “Claim 1 describes gel spinning as the manner by which the filaments comprised in the claimed colored multi-filament yarn are obtained. This, on its face, is a product-by-process claim element because it describes the filament structure being obtained in a particular way, i.e., by gel spinning. See Kamstrup A/S v.

Hoffman-La Roche Ltd, 580 F.3d 1340, 1365–67 (Fed. Cir. 2009). Patent Owner argues persuasively that gel spinning imparts structural and functional differences to the claimed product because the process “creates overlap between polyethylene molecules within the UHMWPE filaments that maximizes the intermolecular Van der Waals interactions, resulting in highly crystalline filaments with high tensile strength.” Prelim.

    “The express language of the claim, however, does not support using the “central axis” as the measuring point for determining if one object is laterally offset from another. For example, the term “central axis” is not used in the relevant claim phrase and the dictionary definitions of “lateral” relied upon by Petitioner and Mr. Jobin to show the ordinary meaning of the claim term do not suggest that the “central axis” is the reference point for determining whether a first object is “laterally offset” from a second object.

Prelim. Resp. 54. We must also resolve whether the entire groove is required to be laterally offset from the chamfered mandrel, or only a portion of it.

    “evidence. The challenged claims require that a sacrificial anode be placed within a certain distance—10 inches—of the hot liquid inlet, and, because the inlet has some non-zero size, it might be possible for an anode to be within that distance from some parts, but not from all parts, of the inlet. Accordingly, specifying the center axis of the inlet as the point from which to measure the distance to the anode improves on the plain words of the claim in terms of achieving the claim’s objective of placing the anode within a specified distance of the inlet. Moreover, when discussing the distance from the inlet to the anode, the specification of the ’494 patent uses the language “within 10 inches in any direction of the center axis of the inlet connection.” Ex. 1001, 7:61–64. Thus, the intrinsic evidence supports adopting Petitioner’s claim construction. Petitioner’s declarant, Dr. Medlin, relies on Petitioner’s proposed construction. See, e.g., Ex. 1004 ¶¶ 20 (noting that the construction “within 10 inches of the center axis of [a] hot liquid inlet” “ha[s] been adopted by Petitioner”), 96 (“the sacrificial anodes contained in each of the turbulators 2 would be placed within 10 inches of a center axis of a hot liquid inlet to the radiator of Tomosada”), 144 (“A POSITA would understand from Figure 1 that the sacrificial anode 14 is within 10 inches of a center axis of a hot liquid inlet”), 267 (“These teachings would further motivate a POSITA to located the sacrificial anode 12 within 10 inches of a center axis of the hot liquid inlet.”). This support for Petitioner’s proposed construction provides further reason for us to adopt it. Because it is supported by the intrinsic evidence of record, because Patent Owner proposes no alternative construction, and because Petitioner’s expert supports it, we adopt the construction of “within 10 inches of a hot liquid inlet to the radiator” that Petitioner proposes. Thus, we construe this term as “within 10 inches of the center axis of a hot liquid inlet to the radiator.” In other words, when discussing the distance between a hot liquid inlet and a sacrificial anode, we interpret “hot liquid inlet” as “center axis of the hot liquid inlet.”” slip op. at 5

In both cases, however, “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” Therasense, Inc. v. Becton, Dickinson & Co., 593 F.3d 1325, 1332 (Fed.

Instead, “the limitation at issue necessarily must be present, or the natural result of the combination of elements expressly disclosed by the prior art.” Par Pharma., 773 F.3d at 1195–96. Here, Petitioner has not shown sufficiently that, in Godefroy, the sacrificial anode necessarily is placed within 10 inches of the center axis of the hot liquid inlet. Dr. Medlin testifies that Figure 1 of Godefroy shows that “an entirety . . . or at least a significant portion of the sacrificial anode 14, is within 10 inches of a center axis of the inlet.” Ex. 1004 ¶ 144. But we cannot say that Figure 1 of Godefroy is clear on its face, or reasonably suggests, that this is necessarily the case. There are no dimensions shown on Figure 1, so it is unclear from the figure what the diameter of pipe 12 is. If that diameter is larger than 20 inches, then it simply is untrue that “sacrificial anode 14 is . . . necessarily placed within 10 inches of a center axis of a hot liquid inlet to the radiator,” as Dr. Medlin testifies. Id. ¶ 361. As noted above, neither Petitioner nor Dr. Medlin relies on the hot liquid inlet of Godefroy having any particular diameter, and Godefroy is silent as to the diameter of its inlet. Pet. 69–70; Ex. 1004 ¶¶ 144, 359–361, 381–382, 406–408; Ex. 1008, 1–15. Moreover, as Patent Owner notes, there is a wide range of sizes of radiators, including automobile radiators, available. Prelim. Resp. 3–5; Exs. 2001–2003. In the absence of any testimony or other evidence that tends to show that radiator inlet pipes necessarily have diameters less than 20 inches, Petitioner has not shown sufficiently that the diameter of Godefroy’s inlet pipe is small enough to ensure that any portion of the anode necessarily is within 10 inches of the center axis of the inlet.” slip op. at 11

    “‘[a]djusting assembly’ is not a recognized term of art in the field of the ’498 Patent” and “[a]s used in the claims of the ’498 Patent, it should be construed as a means-plus-function (‘MPF’) claim element under 35 U.S.C. § 112(f).” Pet. 9 (citing Ex. 1108 ¶ 47). Petitioner bases this assertion on its expert’s opinions that “claim 1 does not recite sufficient structure for performing th[e] function” recited in the “adjusting assembly” limitation and that a person of ordinary skill in the art “would not consider ‘adjusting assembly’ to refer to any specific structure.” Id. (citing Ex. 1108 ¶ 52); see also id. at 10 (citing Ex. 1108 ¶¶ 54–59) (“Nor do the claims otherwise recite sufficient structure for providing the claimed function.”) Further, Petitioner contends that “[c]laim 1 uses ‘adjusting assembly’ as a ‘nonce’ term that operates as a substitute for ‘means’ to claim a function.” Id. at 10 (citing MTD Prods. Inc. v. Iancu, 933 F.3d 1336, 1341–45 (Fed. Cir. 2019) (holding “mechanical control assembly” operated as nonce term)). For its part, “Patent Owner agrees that means-plus-function treatment is appropriate for the ‘adjusting assembly,’” although taking this position “[f]or purposes of this proceeding only.” Prelim. Resp. 8 n.5. Based on the current record, we agree with the parties’ positions that the “adjusting assembly” limitation of the ’498 patent should be construed according to 35 U.S.C. § 112(f). Although the word “means” does not appear in the limitation, the claim language itself does not recite structure that, per the recited function, “cooperat[es] between the first component and the at least second component” and “changes [the] magnitude” of “the force required to be applied in the second manner to reconfigure the apparatus and move the second component relative to the first component,” “as an incident of the force being applied in the first manner changing in magnitude.” In other words, claim 1 appears to lack sufficient structure for performing the stated function of the “adjusting assembly.” See Williamson, 792 F.3d at 1348. Mr. Koepke’s opinion, which is unrebutted at this point, that the term “adjusting assembly” would not connote any specific structure, to a person of ordinary skill in the art, at the relevant time (see Ex. 1108 ¶ 52), supports our conclusion that 35 U.S.C. § 112(f) applies to the “adjusting assembly” limitation. slip op. at 19

    “on incorrect aspects of Petitioner’s proposed construction because Petitioner’s faulty construction fatally undermines Petitioner’s anticipation challenges. We agree with Patent Owner that Petitioner’s construction fails to give adequate weight, or any weight, to the “plurality of gears” aspect of the “adjusting assembly” limitation. Petitioner acknowledges the “plurality of gears” language when arguing that the presence of this structure in the claim does not prevent that the “adjusting assembly” limitation from being construed as a means-plus-function limitation, but Petitioner does not include the functional requirements of the gears in its identification of the claimed function or identify the gears as part of the structure in the Specification that performs the claimed function. See Pet. 13–17. Both of these approaches are erroneous and lead to an incorrect construction of the “adjusting assembly” limitation. The adjusting assembly limitation requires “an adjusting assembly comprising a plurality of gears that cooperate and move relative to each other as an incident of the seat moving from the first position into the loaded position configured to thereby increase a resistance to changing of the angular orientation of the back rest from the starting angular position.” Ex. 1001, claim 1 (emphasis added). Accordingly, the plain language of the claim requires an adjusting assembly that includes gears that perform a certain function (“cooperate and move relative to each other . . .”).

    “Given this, to show that Blangero’s disclosure of MgO or LiF in its coating teaches or suggests a rock-salt crystal structure, Petitioner needs to explain why a person of ordinary skill in the art either would have understood the compounds to have a rock-salt crystal structure when manufactured according to the disclosure of Blangero or would have chosen to use MgO or LiF in a rock-salt crystal structure rather than in another available form. On the first point, Petitioner argues that “‘the stable phase at room temperature and pressure conditions’ of MgO is ‘a rocksalt cubic structure of NaCl (space group Fm-3m).’” Pet. 28 (quoting Ex. 1030, 16; citing Ex. 1003 ¶ 142). But, as Petitioner’s declarant, Dr. Hayes, points out, Blangero does not teach forming MgO in a room-temperature process. Ex. 1003 ¶ 142 (Blangero’s “second firing step” occurs at “925 °C for 12 hours”); see Ex. 1005 ¶ 110 (teaching the firing step to which Dr. Hayes refers). Thus, the significance of rock-salt-type MgO being “the stable phase at room temperature and pressure conditions” is unclear. To the extent that Dr. Hayes explains why MgO, which “is well known to crystallize even at substantially lower temperatures,” such as “room temperature and pressure conditions,” would “do so more readily at [a higher temperature of] 925 °C,” this argument is not discussed, nor even cited, in the Petition. Ex. 1003 ¶¶ 90–94; see Pet. 28. Accordingly, any reliance on this argument by Petitioner constitutes improper incorporation by reference. 37 C.F.R. § 42.6(a)(3). Thus, Petitioner does not show sufficiently that a person of ordinary skill in the art either would have understood MgO to have a rock-salt crystal structure when manufactured according to the disclosure of Blangero or would have chosen to use MgO in a rock-salt crystal structure rather than in another available form. Similarly, with respect to LiF, neither Petitioner nor Dr. Hayes sufficiently explains the choice of rock-salt-type material over other options. Pet. 29 (arguing only that Ex. 1013 shows that “LiF has rock salt structure”); Ex. 1003 ¶ 143 (same). Thus, Petitioner does not show sufficiently that Blangero teaches or suggests a rock-salt crystal structure by virtue of its teaching that either MgO or LiF is present.” slip op. at 12

    “The 2012 study on which Petitioner relies did not find “superior structural stability” over other lithium-titanium-oxygen compounds, as Petitioner argues. Instead, the study noted that the structure of “LiTiO2 prepared by high-temperature sintering TiO2 with lithium salt . . . impl[ies] LiTiO2 has superior structural stability in organic electrolyte as compared to other Li-Ti-O oxides.” Ex. 1029, 1. Thus, the structural stability was implied from the chemical structure of the material rather than found through study of the material. Moreover, the implied structural stability was only for LiTiO2 that was prepared in a particular way, by high-temperature sintering of TiO2 with lithium salt, and Petitioner does not allege that a person of ordinary skill in the art would have prepared the LiTiO2 they substituted for Blangero’s Li2TiO3 using this method. As for Petitioner’s argument that the study found that LiTiO2 outperformed Li2TiO3, we are not persuaded. The study compared particles with an LiTiO2 coating to uncoated particles, not to particles coated with Li2TiO3. Ex. 1029, 4, Figs. 4(c), 4(d). Although the study notes that particles coated with “[m]onoclinic Li2TiO3 and spinel Li4Ti5O12” exhibit “a noticeable capacity decay . . . when charged at high operating voltage and cycled above room temperature,” it concludes only that particles coated with LiTiO2 “exhibited inspiring high-voltage cycling capability as well as thermal stability than the pristine counterpart.” Id. at 1, 4. In addition, the pristine particles used in the study were made from “Li[NixCoyMnz]O2 (0≤x,y,z<1) (called as LNCM),” and the particles in Blangero do not contain either nickel or manganese in their cores. Ex. 1005 ¶¶ 9–40 (particles contain lithium, oxygen, cobalt, and metals chosen from the group consisting of aluminum, gallium, boron, magnesium, titanium, iron, copper, calcium, barium, yttrium, tin, antimony, sodium, zinc, zirconium, silicon); Ex. 1029, 1. Petitioner does not explain why a person of ordinary skill in the art would expect the study’s results to extend to Blangero’s particles made from a different material. Pet. 29–30. Because Petitioner has not shown sufficiently that Blangero teaches or suggests a second region comprising a rock-salt crystal structure or that a person of ordinary skill in the art would have had a reason to substitute rocksalt-type LiTiO2 for the materials disclosed in Blangero, Petitioner has not shown a reasonable likelihood that it would prevail on claim 1 on its Blangero-based grounds.” slip op. at 15
