In particular, Patent Owner argues that a person of ordinary skill in the art “would not have been motivated to look into Penven to modify the teachings of Lee because Lee and Penven disclose substantially different structures.” Id. at 60–61. This argument does not address Petitioner’s proposed reason to combine, which looks to Lee and Penven each to modify Sudre, not to Penven to modify Lee. See Pet. 79–81. In addition, “[c]ombining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). In other words, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425–26 (CCPA 1981). Petitioner provides “some articulated reasoning with some rational underpinning” to combine the teachings of Sudre with those of Lee and Penven. KSR Int’l Co. v.

“protective layers have “a coat weight of from 5 to 30 lbs/3000 ft2,” Clearwater submits the declaration of its expert, who explains that, because Nakagawa identifies the specific polymers and the thickness of the coat used for the plastic layers and one skilled in the art “would recognize that the disclosed polymers have a given density,” then “[w]ith these known parameters, the coat weight is easily calculated to be 23.04 lbs./ 3000 ft2 — falling squarely within the claimed range.” Pet. 53–54 (citing Ex. 1003 ¶¶ 132–133; Ex. 1008 ¶ 24; Ex. 1024, at 4). At this stage, we find that testimony credible and supported by the evidence presently of record. After reviewing the preliminary record (including Clearwater’s contentions, the cited portions of Nakagawa, and the testimony of Clearwater’s expert), we find, preliminarily, that Nakagawa discloses or otherwise suggests each claim element in the manner recited by claim 1. Thus, on the current record, Clearwater demonstrates a reasonable likelihood that challenged claim 1 is unpatentable as obvious over Nakagawa. We need not decide Clearwater’s challenge of the dependent claims based on Nakagawa alone nor its challenge of claims 1–3 based on Nakagawa and Tanner.

“On this record, we are persuaded that Petitioner adequately establishes that Usui discloses all of the limitations of claim 1. Usui discloses that aluminum or aluminum alloy layer 15 is in electrical contact with titanium underlayer 13, and titanium nitride layer 14 is located “intermediate the [titanium underlayer] 13 and the aluminum or aluminum alloy layer 15” to prevent “reaction between the aluminum layer 15 and underlayer 13.” Ex. 1004, 3:27–29, 3:38–41, 3:58–63. Usui further discloses that “a capping layer is provided above layer 15,” and that “[p]referred capping layers are titanium nitride and combinations of as layer 18 of a group IVA metal, preferably titanium with a titanium nitride layer 19.” Id. at 3:67–4:6. Usui teaches that titanium nitride layer 19 is about 150 to 800 Å thick, and that the thickness of titanium underlayer 13 is between about 90 to 110 Å. Id. at 3:31–33, 4:6–8. Usui also teaches that the interconnect metallurgy structures described therein “exhibit[] enhanced electromigration characteristics” and “are especially useful for forming electrical connections or wiring such as between active and/or passive devices of an integrated circuit structure.” Id. at 1:8–14. Usui’s description of a plurality of metal layers (layers 13–18) and a capping layer formed over the plurality of metal layers (layer 19), along with its description of the structure’s usefulness for forming electrical connections in an integrated circuit structure, is sufficient, on this record, to establish that Usui discloses “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. Usui’s teaching that the capping layer is a refractory metal nitride (titanium nitride) that has a thickness (150–800 Å) greater than the bottommost layer of the plurality of metal layers (layer 13, 90–110 Å), sufficiently establishes, on this record, that Usui discloses the “said capping layer consisting only of a refractory metal nitride, said refractory metal nitride forming a top of said electrical contact and having a thickness greater than that of a bottommost layer of said plurality of metal layers” limitation of claim 1.” slip op. at 11

“Patent Owner argues that Petitioner does not show sufficiently that a person of ordinary skill in the art would have had a reason to modify Bonn to remove local oscillator 55. Prelim. Resp. 13–15. We disagree. Petitioner argues that, “[i]n addition to using Figure 7’s ‘dual gate FET structure in high frequency signal mixing’ applications . . . , Bonn discloses using this dual gate FET in ‘other applications such as high frequency signal amplification.’” Pet. 22 (quoting Ex. 1006, 11:26–37). Indeed, Bonn does suggest using its structure for signal amplification. Ex. 1006, 11:26–37 (“the dual gate FET structure of the present invention can be tailored to provide superior performance . . . in . . . other applications such as high frequency signal amplification”). On the present record, this appears to have provided the motivation for a person of ordinary skill in the art to use Bonn for amplification instead of for signal mixing. Petitioner relies on the testimony of Dr. Bernstein to show the modifications that a person of ordinary skill in the art would have considered necessary in order to convert Bonn’s structure for signal-amplification use. Pet. 23–25 (citing Ex. 1003 ¶¶ 98–109). In particular, Petitioner cites Dr. Bernstein’s testimony that a person of ordinary skill in the art “would have found it obvious to remove Figure 1’s LO (local oscillator) port 55 and its associated impedance matching components because the LO signal is no longer being mixed.” Ex. 1003 ¶ 98; see Pet. 23. Dr. Bernstein supports this testimony with citations to Bonn and with reasoning regarding why a person of ordinary skill in the art would have made this modification. Ex. 1003 ¶ 98 (citing Ex. 1006, 1:20–23, 3:19–21, 3:30–41). Accordingly, on the present record, we are persuaded that Petitioner has shown sufficiently that a person of ordinary skill in the art would have had reason to modify Bonn’s structure to remove the connection between a local oscillator and the gate of the second transistor. Finally, Patent Owner argues that Petitioner’s proposed modification would have rendered Bonn inoperable for its intended purpose because the modification would eliminate the ability of Bonn’s structure to conduct high frequency signal mixing. Prelim. Resp. 26–27. As Patent Owner notes, one purpose of Bonn is to mix high-frequency signals. Ex. 1006, 11:33–36. But Bonn itself teaches using its structure for “other applications,” including “high frequency signal amplification.” Id. at 11:33–37. Thus, on the present record, we are persuaded that Petitioner’s proposed modification does not render Bonn inoperable for its intended purpose so much as it acknowledges the modifications necessary to convert Bonn from one of its intended purposes to another. Thus, Petitioner has shown sufficiently for the purpose of the present Decision that a person of ordinary skill in the art would have had reason to combine Bonn and Mizuta and that the combination of Bonn and Mizuta teaches or suggests the disputed limitation of claim 1.

“Owner’s challenge to Petitioner’s Fukui-based grounds is whether, in Fukui, a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette.11 We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) forming “one body” (see, e.g., id. at 8:2–3). Further still, as described and shown in Fukui (e.g., Figure 5), conversion module 20 is structured to operate via a singular multicore optical connector 16 from which optical fibers F1 extend to all of the single-core optical connectors 17 of the conversion module. Id. at 7:52– 11 There is no dispute on this record that the term “module” as used in Fukui is analogous to the term “cassette” as used in the ’423 patent. 8:6.

“At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments. Patent Owner does not cite to evidence, such as expert testimony, to support its implied argument that Olson’s measured current is “fundamentally different” from the current received by the primary coil. See Prelim. Resp. 31–32. Petitioner’s declarant, Dr. Woods, on the other hand, testifies, inter alia, that “[t]he ‘[c]urrent measured by current measure block 226 is used in the calculation of power, which as depicted in FIG. 14, measures the ‘power in’ provided to transmit block 214/primary coil 54.” Ex. 1003 ¶ 37 (citing Ex. 1004 ¶¶ 74–75, Fig. 14) (first alteration added); see also, e.g., id. ¶ 42 (Dr. Woods testifying that the measured current to the power supply “is the current driving the external antenna 52, via the transmit block 214 and to the primary coil 54.” (citing Ex. 1004 ¶¶ 74–75, 112, Fig. 14)). Paragraph 75 of Olson, cited in support of that testimony, provides: “The power in is gauged by the power generated by charging unit 50 and is determined by multiplying the voltage of the internal voltage of charging unit 50, e.g., the voltage of a battery or batteries internal to charging unit 50, by the current driving external antenna 52.” Ex. 1004 ¶ 75 (emphasis added). We note that external antenna 52 includes primary coil 54. See, e.g., Fig. 14. Dr. Woods’ testimony is, at this stage, unrebutted. Patent Owner also argues that “Petitioner fails to provide any evidence regarding the function of Olson’s microprocessor 212 in relation to measuring input power,” and that, “[w]hile Olson describes a power calculation in paragraph [0075], Olson does not describe this power calculation as performed by microprocessor 212.” Prelim.

Although Patent Owner does not bear the burden to show patentability, we observe that Patent Owner does not suggest that there is another component in Olson’s external charging device that might perform the admittedly-disclosed power calculation. See Prelim. Resp. 32–33. Dr. Woods testifies that microprocessor 212 receives the measured current and the input voltage of the charging device, and, from those values, calculates power in. See Ex. 1003 ¶¶ 43–44 (citing, inter alia, Ex. 1004 ¶¶ 71–78, Fig. 14); see also Ex. 1004 ¶ 74, Fig. 14 (Olson stating that “[c]urrent measured by current measure block 226 is used in the calculation of power in along with the voltage of batteries 160,” and Figure 14 depicting the signal from measure block 226 as an input to microprocessor 212).
