    “constructions. First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

Ex. 2006 ¶ 119.

Prelim. Resp. 3.

As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision.

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted

    “Contrary to Patent Owner’s arguments, the law on overlapping ranges in obviousness challenges is clear. See In re Peterson, 315 F.3d 1325, 1329 (Fed. Cir. 2003) (“A prima facie case of obviousness typically exists when the ranges of a claimed composition overlap the ranges disclosed in the prior art.”). Here, Petitioner directs us to evidence of an overlapping range, which is not meaningfully disputed by Patent Owner. As to Patent Owner’s arguments regarding the lower end of the claimed range of aspect ratios and Ohata’s warning about aspect ratios below 100, we note that Ohata states that its carbon nanotubes “preferably have an aspect ratio . . . of not less than 100,” and expressly includes examples with an aspect ratio of 50. Ex. 1004 ¶ 20 (emphasis added), Table 2 (Examples 12 and 14). Patent Owner also criticizes Petitioner for relying on oxidizing Ohata’s nanotubes in view of Kavan (discussed in more detail below). Prelim. Resp. 6. According to Patent Owner, oxidation is known to shorten the length of nanotubes, which would impact the aspect ratio of the nanotubes in the proposed combination. Prelim. Resp. 6. Specifically, Patent Owner contends that oxidizing Ohata’s nanotubes will reduce the aspect ratio below 100, and argues that “Petitioner has not explained why a [person of ordinary skill in the art] would ignore Ohata’s warning nor has Petitioner provided evidence that the resulting combination will perform as Petitioner alleges.” Prelim. Resp. 7; see also Prelim. Resp. 8 (arguing Petitioner has not explained why a person of ordinary skill in the art would try to retain Ohata’s aspect ratio and expect success when Ohata is altered in view of Kavan). Even giving Patent Owner’s arguments their full weight, there is no evidence on the present record as to how much the aspect ratio of Ohata’s nanotubes would be reduced as a result of oxidation. Rather, based on the present record, namely, the broad range of aspect ratios disclosed in Ohata (preferably 100–1000), it seems reasonably likely that the aspect ratio of at least some of the oxidized nanotubes in the proposed composition would remain within the range disclosed in Ohata and overlap the claimed range, as Petitioner asserts. Nevertheless, the parties may address during trial the expected level of carbon nanotube shortening in the proposed combination of Ohata and Kavan.” slip op. at 21

    “To the extent Patent Owner is presenting a teaching away argument, these statements do not rise to the level of criticizing, discrediting, or discouraging investigation into the claimed invention. DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009). Indeed, in addition to its statement regarding oxidation not being necessary for anchoring to TiO2, Kavan also states that oxidation of carbon nanotubes “was sometimes mentioned to improve anchoring of TiO2.” Ex. 1005, 2. Moreover, the full statement from Kavan regarding storage capacity reads: “The Li-storage capacity of TiO2 is not enhanced in the composite, but the rate of electrochemical charge transfer is higher due to nanotube networking.” Ex. 1005, 9. Thus, in its entirety, this statement supports Petitioner’s argument that there are advantages to using oxidized nanotubes, and, in turn, provides a reason why a person of ordinary skill in the art would have used oxidized nanotubes. Moreover, the evidence Petitioner presents regarding the use of oxidized nanotubes in combination with TiO2, coupled with Ohata’s statement that the electrode active material to be used can vary depending on the battery type (Ex. 1004 ¶¶ 26–27), undermines Patent Owner’s criticism that Petitioner’s arguments are circular.” slip op. at 24

    “combined Lee and Watanabe to achieve improved integration density. Pet. 71. Petitioner concedes, however, that the benefits of Lee’s design related to 3-D integration and improved integration density would be obtained if Lee’s memory structures are formed using either Lee’s monolithic construction method or Watanabe’s alternative stacking method. Pet. Reply 13–14 (citing Ex. 1041 ¶ 34). Thus, we are not persuaded that improved integration density provides a sufficient rationale for Petitioner’s combination of Lee’s memory device and Watanabe’s stacking method. Petitioner argues that Watanabe’s stacking method “improves the accuracy of the wiring” because the wiring is made “for each planar member.” Pet. 72 (citing Ex. 1005, 6:1–3). Watanabe also states that its disclosed methods provide “a low interconnection wire resistance.” Ex. 1005, 6:20–23. Petitioner does not, however, explain sufficiently how Watanabe’s stacking method would improve Lee’s device. For example, Petitioner does not address whether the alleged wiring benefit already existed in Lee’s monolithic array or explain how this benefit would also apply to Lee’s particular memory array, which differs in construction and elements from Watanabe’s device. This diminishes Petitioner’s benefits-based motivation to combine arguments. In general, a petitioner need not demonstrate that a particular alternate method would improve a prior art device in order to show a motivation to combine. Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023); see Pet. Reply 20 (citing Intel). But here, Petitioner affirmatively invokes improvement of Lee’s device as a reason for the combination, and we must evaluate Petitioner’s contention. Moreover, any relative lack of improvement or benefits must be weighed against any problems the alternative method would introduce. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 795–96 (Fed. Cir. 2021) (noting that simultaneous advantages and disadvantages to a proposed combination must be analyzed to determine whether the disadvantages “outweighed any reason to combine”). Here, as discussed above in more detail with respect to the ground based on Watanabe, the evidence shows that one of ordinary skill in the art would have expected Watanabe’s bonding temperature of 900– 1000° C to damage the electronic devices in an underlying substrate. Ex. 2029 ¶¶ 75–76; Ex. 2028, 123:13–124:7; Ex. 2027, 715.

    “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

Indeed, the Specification describes this term, as follows: Gel spinning is understood to include at least the steps of spinning filaments from a solution of ultra-high molecular weight polyethylene in a spin solvent; cooling the filament obtained to form a gel filament removing at least partly the spin solvent from the gel filament; removing at least partly the spin solvent from the gel filament; and drawing the filament in at least one drawing step before during or after removing spin solvent.

    “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. Axioma Metering UAB, 43 F.4th 1374, 1382 (Fed. Cir. 2022) (agreeing with the Board that “cast in one piece” is a product-by-process claim element as it describes the structure being cast “in a particular way”). For this element to be limiting, it must impart “structural and functional differences” that distinguish the claimed product from the prior art. See Amgen Inc. v. F. 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. Resp. 38, 22 (citing Ex. 1014, 62–66).

    “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. As such, we determine that the claim language supports Patent Owner’s construction requiring that the “groove” be “off to the side” of the entire mandrel, and not merely the “central axis” of the mandrel. 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. On this point, the claims do not use the term “portion,” but rather specify that the “groove” is “laterally offset from the chamfered mandrel.” Ex. 1001, 14:4– 5, 15:19–20.

    “That argument, however, does not explain why it would have been obvious to laterally offset the groove of Yoakim from the chamfered mandrel. Rather, as demonstrated by Mr. Jobin’s testimony, this argument relates to the general use of a sealing member in a groove, to the extent it was ultimately determined that such a configuration is not expressly disclosed in Yoakim. Id.; Ex. 1003 ¶ 296 (“It would have been obvious to one skilled in the art to position a sealing member in a groove to solidify the between counter-force portion 161 and engaging portion 157 in Figure 35 of Yoakim is more appropriately identified as the claimed “groove.” Prelim.

We need not resolve this issue, however, as Petitioner does not persuasively demonstrate that either potential “groove” is “laterally offset” from the chamfered mandrel. placement of the seal and improve its sealing stability and strength. Furthermore, it would have been obvious to one skilled in the art to utilize a groove and seal configuration in the brewing head . . . .”) (emphasis added). Even if we interpret the recited portion of the Petition as an argument for placing the groove entirely to the side of the mandrel in Yoakim, the Petition does not persuasively explain why one of ordinary skill in the art would have sought to do so. In Figure 35 of Yoakim, the seal and groove, as well as an elastic loading means, act as a valve means to control the level of pressure exerted in the capsule and “optimize interaction of water and the ground coffee particles to obtain a good extraction of the coffee and aroma compounds.” Ex. 1004 ¶¶ 370–372, 382, 396–398, 434–436, 445; Ex. 1003 ¶¶ 286–290; Pet. 63.

    “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

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.
