    “comprises the recited metals and has the recited thickness, which forms an electrical contact for use on a semiconductor device generally or a group III- V semiconductor in particular. This is consistent with our determination that “electrode stack” is a conductor that provides a path for current entering or leaving a medium such as a semiconductor device We disagree with Patent Owner that “electrode stack” as used in the challenged claims should be limited to the specific electrodes shown in the embodiments described in the Specification. See PO Resp. 4–9. Although the Specification describes embodiments using source, drain, and Schottky gate electrodes as electrical contacts, we see no reason to construe the term “electrode stack” itself to be limited to these components as Patent Owner proposes. Claims 1 and 13 expressly recite that electrode stacks comprise the claimed “electrical contact,” without expressly including or precluding any specific type of electrode. Ex. 1001, 5:54–63, 6:37–47. The Federal Circuit advises that the Specification “is not a substitute for, nor can it be used to rewrite, the chosen claim language. ‘Specifications teach. Claims claim.’” SuperGuide, 358 F.3d at 875 (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 n.14 (Fed. Cir. 1985) (en banc)). The Specification does teach electrical contacts that include source, drain, and Schottky gate electrodes, but claims 1 and 13 are directed to electrical contacts that are not expressly so limited. Patent Owner’s proposed construction would effectively rewrite the claim by adding limitations, which we decline to do under the guise of claim construction. See id. (“Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import into a claim limitations that are not a part of the claim.”). In view of the foregoing, we construe the claim term “electrode stack” to mean “a conductor that provides a path for current entering or leaving a medium such as a semiconductor device.”” slip op. at 17

    “that the identified layers in Usui’s interconnect metallurgy structure form an “electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1. See Pet. 11–12 (citing Ex. 1002 ¶¶ 89–91). Neither Petitioner nor Dr. Zhao, however, provide adequate explanation or evidence as to why Usui’s interconnect metallurgy structure forms an “electrode stack,” i.e., a conductor that provides a path for current entering or leaving a medium such as a semiconductor device. Dr. Zhao’s testimony merely repeats the disclosures in Usui and concludes, without further technical detail, explanation, or reference to objective evidence, that Usui’s Figure 8 discloses an electrode stack. Ex. 1002 ¶¶ 89–91. Dr. Zhao’s testimony sets forth Petitioner’s conclusory assertions as though they are facts, rather than setting forth facts and evidence in support of those assertions. Compare id. with Pet. 11–12. Absent underlying facts or evidence to support Dr. Zhao’s opinion, the cited testimony “adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In contrast, Patent Owner’s declarant Dr. Piner testifies, with evidentiary support, that interconnects (such as Usui’s interconnect metallurgy structure) and electrical contacts (such as that claimed in the ’562 patent) are not the same thing. See Ex. 2024 ¶¶ 63–70. For example, Dr. Piner explains: In other words, not all metals in a semiconductor device have the same purpose and could not be said to be interchangeable. By August 2009 it was well known to a POSA how to discern if a metal component in a transistor is an interconnect or serves as an electrical contact such as a gate contact or ohmic contact, based on the structure and functionality of the metal component. For example, interconnects are made up of metal strips and are deposited on insulators. EX-1011 (Mishra) at 216. Interconnects are low resistance conductors that can carry very high current densities. Id., 216, 217. Unlike Schottky contacts and ohmic contacts, interconnects do not provide non-linear IV response like Schottky contacts nor inject electrons and holes into semiconductors like ohmic contacts. Id., 218. As many of the references cited by Dr. Zhao illustrate, electrical contacts had their own highly complex design challenges. EX-1008 (Pearton), 41-59 (Pages 53-71 of 383) (discussing electrical contacts); EX-1017 (Kramer), 11-126 (Pages 18-130 of 151) (same). And while Dr. Zhao cites these as supporting a POSA’s knowledge of an electrical contact, none of these references describe electrical contacts as interconnects. Id. ¶ 71. Dr. Piner further testifies that Usui’s interconnect metallurgy structure is an interconnect, and not an electrical contact, because “Usui states that ‘[t]he structures fabricated by the process of the present invention are especially useful for forming electrical connections or wiring such as between active and/or passive devices of an integrated circuit structure.’” Id. ¶ 148 (citing Ex. 1004, 1:11–14) (alteration in original); see also id. ¶¶ 150– 151 (Dr. Piner testifying that Usui’s interconnect metallization structure is not an “electrode stack” under a broad definition of electrode).

    “conductor that provides a path for current entering or leaving a medium such as a semiconductor device.” Thus, Petitioner must show that Usui’s layers 13–15, 18, and 19 provide a path for current entering or leaving a medium such as a semiconductor device. After reviewing the complete trial record, we are not persuaded that Petitioner has done so. Petitioner relies on the testimony of Dr. Zhao to support its contention that the identified layers in Usui’s interconnect metallurgy structure form an “electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1. See Pet. 11–12 (citing Ex. 1002 ¶¶ 89–91).

    “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

  • BurdenNot shown unpatentable

    “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

    “Petitioner’s arguments are not persuasive. Mr. Cornelison’s testimony that a POSITA would understand that the tape shown in Figure 13C “has three layers aligned along the side edges” is not credible. See, e.g., Ex. 1006 ¶ 138. Mr. Cornelison’s testimony that Figure 13C is only “intended to identify and illustrate the three different layers of the multi-layer tape,” not to show the relative positions of the layers relative to each other (id. ¶ 137), is belied by his own testimony, in which he states that Figure 13C shows “metallic layer 133 extends to the front edges of dielectric layers 135 and 137 (id. ¶ 136). Additionally, neither Petitioner nor Mr. Cornelison provide persuasive evidence to support the contention that it would take “much more time and be more complex to make all three layers” in Figure 13C offset from each other or that it would be more costly to make than using the customary slitting processes. See Ex. 1006 ¶ 138. Although Mr. Cornelison provides evidence as to how the slitting process can be used to manufacture barrier tape, he does not provide any evidence to support his contention that the proposed slitting processes is in fact less expensive or complex than other methods. See Ex. 1006 ¶ 138. Indeed, Mr. Cornelison does not address the particular methods disclosed in Glew to manufacture the disclosed multi-layer tapes nor persuasively explain why these disclosed methods would be more costly or complex as compared to the “slitting” process. Ex. 1008 ¶¶ 199–201 (stating the multi-layer tapes can be manufactured in a “variety of ways” including bonding the various layers using adhesive or other bonding agents,” mechanically affixing or bonding the layers, needlepunching, thermal bonding, ultrasonic welding, or calendar bonding). We determine that this portion of Mr. Cornelison’s testimony is conclusory and unsupported and is entitled to little weight. Accordingly, Petitioner has not sufficiently shown that Glew discloses conductive material that extends to the lateral edges of the dielectric material as required by claims 1 and 18. As such, Petitioner has not shown a by a preponderance of the evidence that Glew anticipates independent claims 1 or 18 or the challenged claims that depend therefrom.” slip op. at 42

    “Thus, although the Specification does not use the term “lateral edge,” the Specification and figures of the ’030 patent make clear, that in the embodiments having a conductive layer that extends to the edges of the dielectric layers of the tape, the referred to “edge” is the edge of the “long side” of the tape that extends in the longitudinal direction. See, e.g., Ex. 1001, 7:49–51 (stating in some embodiments conductive layer 302 may not extend to the edge of tape 110), 8:1–25 (stating, inter alia, pairs 102 could electrically couple to the corresponding edge 306 resulting in increased ANEXT), 8:41–46, 10:30–36 (stating that the tape edge lies over a pair of conducts and the pair generates more ANEXT). Our construction of term “lateral edge” is supported by Roberts, which also refers to the edges of the long side of the tape extending in the longitudinal direction as the “lateral edges.” See, e.g., Ex. 1009, 2:20–24 (“a shield made from a plurality of tapes helically disposed, the lateral edges of which overlap adjacently lying tapes”), 2:42–46 (“a shield composed of a plurality of …, the lateral edges of which overlap adjacently disposed tapes”), 4:27–33 (“the plastic-coated metal foil shield (15) [FIG. 2] has lateral edges that overlap,” “the lateral edges of the shield overlapping one another”), 4:34–40 (“The lateral edges of the helically disposed tapes [of FIG. 3] overlap adjacently lying tapes.”), 5:65-75 (“the shield (15) [of FIG. 10] is made up of a plurality of tapes, the lateral edges of which overlap adjacently disposed like tapes”), Figs. 2, 3, 10. We credit Dr. Eldering’s testimony that these disclosures of Roberts shows that a POSITA would understand that a tape’s “lateral edges” are the edges running along the sides of the tape parallel to the longitudinal direction.

Nor has Petitioner shown that Dimov inherently discloses selectively recovering any particular cell that has been cultured and monitored, because, as Dr. Gale persuasively testifies, Dimov’s removal techniques could, as far as a person of ordinary skill in the art would have known based on Dimov’s disclosure, be merely for “removing . . . unwanted particles out of the capture chamber/trench.” Ex. 2012 ¶ 64; see also id. ¶ 63 (“Dimov . . . may suggest removing cellular materials (rather than intact cells) after capture . . . .”). In other words, given Dimov’s general focus on performing experiments within the trenches and the lack of any specific disclosure about how or why to remove cells, Petitioner has not met its burden to show that Dimov’s potential cell-removal techniques would have necessarily been based on a response of a specific cell being cultured and monitored in limitation 1D. We also agree with Patent Owner that Dimov does not disclose any specifics about how to carry out a selective cell removal based on one of Dimov’s listed techniques, such as laser tweezers. See PO Resp. 8–9. Nor does Petitioner meet its burden of showing that such a technique would have been within the ordinary skill in the art at the time of the claimed invention. “In order to anticipate, a prior art disclosure must also be enabling, such that one of ordinary skill in the art could practice the invention without undue experimentation.” Novo Nordisk Pharms., Inc. v.

Id. However, Petitioner’s expert acknowledged that he did not do any testing that would determine whether nanobubbles were formed. Id. at 7 (citing Ex. 2172, 70:1–4). Petitioner’s reliance on milkiness and supersaturation to demonstrate the presence of nanobubbles is also unsupported.

PO Resp. 25–26; Sur-Reply 6–7; see also Tr. 13:24–26 (Petitioner’s counsel agreeing that “you can have supersaturation without milkiness”).

    “suggested formula” assigned to them is “based on a calculation that relied on the average of a wide distribution of particle sizes reported in the literature by Hutchison.” Ex. 2030 ¶ 103(citing Ex. 2017, 12891). We assign persuasive weight to her testimony because it is based upon the disclosures in Hutchison, which Banin explicitly identifies as the published procedures by which it synthesized its clusters. In particular, Dr. Cossairt’s testimony is supported by the following discussion in Hutchison: To calculate an average molecular formula for 1 it is necessary to know the number of gold atoms in the metal core. Given the average particle size (1.5 nm) this number is estimated to be ~101 by the method of Whetten et al. and leads to an estimated formula of Au101(PPh3)21Cl5. Ex. 2017, 12891. In other words, Hutchison explains that it calculated an average molecular formula for its synthesized nanoparticles by estimating the number of gold atoms in the metal core based upon the average particle size of 1.5 nm. Id. Indeed, as Dr. Cossairt has recognized, Banin’s “suggested formula” is exactly the same molecular formula that Hutchison discloses as the “average molecular formula” for its nanoparticles. Thus, we determine that the record as a whole supports finding that a person of ordinary skill in the art would have understood that Banin’s “suggested formula” represents an average molecular formula for a disperse mixture of gold clusters that are not identical and do not have sufficiently well-defined chemical structure such that all molecules of the cluster compound possess the same relative molecular formula, as required for MCCs. slip op. at 23

Ex. 1001, 5:3–9. We note that the District Court determined that “the term ‘molecular formula’ as opposed to ‘molecular mass’ is most appropriate. By necessity, a compound with the same molecular formula will necessarily have the same molecular mass.” Ex. 1091, 16. The District Court explained also, “it appears that the difference between a molecular formula and a molecular mass, at least for purposes of this claim construction, in inconsequential.” Id.

    “We agree with Patent Owner. As set forth above, we interpreted “controlled environment” to mean “an air environment in which one or more conditions are controlled.” See supra Section II.B. Ren discloses controlling the conditions of an isolated, inert gas environment. See, e.g., Ex. 1003, 2:48–54 (“The isolated environment generally comprises . . . means for supplying inert gas into the enclosure and desiccating agents disposed between the inert gas supply means and the enclosure, along with desiccating agents within the enclosure.”), 7:53–57 (“Pumping an inert gas, such as nitrogen, into a sealed environment is an effective means for reducing the oxygen content from in [sic] the surrounding environment, but this does not reduce or eliminate H2O from the surrounding environmental humidity.”), 9:16–20 (“After placing the individually-wrapped packages of magnetic powder into the isolated environment, a flow of inert gas” into the isolated environment is activated, and “[t]he inert gas purges humidity and/or oxygen from the isolated environment.”). Consequently, we are not persuaded that Petitioner has established that Ren teaches “providing a controlled environment having a temperature ranging from 5° C. to 30° C. and a relative humidity ranging from 40% to 65%” as recited in independent claims 1 and 2. Therefore, based on our review of the record, we find that Petitioner has not established by a preponderance of the evidence that claims 1 and 2, and claims 6 and 8 that depend directly therefrom, are anticipated by Ren.
