      “Institution of an inter partes review is authorized by statute when “the information presented in the petition . . . and any response . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a) (2018). Upon consideration of the Petition, the Preliminary Response, the Petitioner Preliminary Reply, the Patent Owner Preliminary Sur-reply, and the evidence of record, we determine that Petitioner has not established a reasonable likelihood of prevailing with respect to the unpatentability of at least one claim of the ’264 patent. Accordingly, for the reasons that follow, we decline to institute inter partes review of claims 1, 3, 6, 11, 13, 15, 20, 21, 23, and 25–27 of the ’264 patent.” slip op. at 2

That is, Petitioner’s position appears to be that the recited limitation could be sufficiently disclosed or met by prior art if it instead meets the different requirement of “not dedicating a specific frequency channel for measuring path loss.” We do not agree.

Petitioner does not appear to dispute its required showing, that is, Petitioner does not argue that the absence of an element in the prior art is sufficient per se to satisfy a negative limitation. Rather, the Petition affirmatively asserts that Almgren discloses or teaches the limitation “without disabling any other communication.” Pet. 25–26.

At this time, Patent Owner does not dispute Petitioner’s proposed construction of “a support pattern, provided on the second surface.” See generally Prelim. Resp.

      “As discussed above in Section II.C, under the heading “SUMMARY OF THE INVENTION,” the ’013 patent states that “[t]he object of the present invention is to provide a wiring substrate, a semiconductor device, and a package stack semiconductor device, all with improved reliability of connection by suppressing occurrence of inadequate electrical connection.” Ex. 1001, 3:60–64 (emphases added). The ’013 patent further states that A wiring substrate of the present invention, in order to achieve the foregoing object, includes an insulating substrate, a terminal section for wire bonding or flip-chip connection and a support pattern, provided on a surface of the other side of the surface where the terminal section is provided, and on a position corresponding to the terminal section, for improving reliability of connection of wire bonding. Therefore, this structure can suppress deformation of the insulating substrate by the support pattern, even when the terminal section is pressed in wire bonding or other connection methods. As a result, reliability of connection in wire bonding or other connection methods, can be improved than conventionally. Id. at 3:65–4:11 (emphases added). In view of these disclosures in the Specification and the express recitation “for improving wire bonding connection” in the claim, we determine that the limitation reciting “support pattern . . . for improving wire bonding connection” requires the recited “support pattern” to be capable of “improving wire bonding connection.” See GPNE Corp. v. Apple Inc., 830 F.3d 1365, 1371 (Fed.

      “establishes that a POSITA would have been motivated to modify Brown in the manner proposed. Brown teaches that its battery casing with the stacking mechanism is used in both single and multi-cell batteries: A cell casing for a primary dry cell battery of the button type is disclosed which includes a case with a first elongated electrically conductive member affixed centrally to its exterior surface, and a cover with a second elongated electrically conductive hollow member affixed centrally to its interior surface in communication with an aperture. Both a single and a multi-cell battery are described which include the above battery casing. Ex. 1005, 1:11–18 (emphasis added). Consistent with this teaching, Brown’s Example I describes a cell casing “formed generally in accordance” with the casing depicted in Brown’s Figure that includes a stacking mechanism, in particular a screw (member 14) welded to the outside center of case 11. Id. at 2:58–81. In Example II, the “non-stacking variant” cited by Petitioner, Pet. 15, Brown teaches using the “cell casing of Example I,” which includes the stacking mechanism, in a single-cell battery. Ex. 1005, 3:1–18. Brown explicitly states that the aperture in the cover is sealed when the cell is used in a single cell battery, but provides for no other” slip op. at 12

      “In light of these disclosures in Brown, neither Petitioner nor Mr. Juzkow sufficiently explains why a POSITA would overlook Brown’s teaching that the casing includes the stacking mechanism regardless of the number of cells in the battery, in order to simplify the manufacturing process and produce a battery with a smooth cup surface that would reduce the space occupied by the battery when only a single cell is used. Pet. 15 (citing Ex. 1002 ¶ 54); see Ex. 1005, 1:11–18, 3:1–18. Notably, Mr. Juzkow’s testimony in this regard merely repeats the conclusory and unsupported assertions in the Petition, without citing to additional evidence or providing any reasoning to support his statement. Mr. Juzkow’s testimony thus adds little to Petitioner’s conclusory assertions regarding a POSITA’s motivation to modify Brown, and is entitled to little weight. Xerox Corp. v.

The parties disagree about whether the references on which Petitioner relies teach or suggest this limitation. Pet. 28–32, 64–66; Prelim. Resp. 53–61. As discussed more completely below, we are able to determine whether to institute trial without deciding precisely what the ’835 patent means when it describes two parts as “held together by a force-fitting connection.” Accordingly, we need not, and do not, construe this term expressly. See Nidec, 868 F.3d at 1017 (quoting Vivid Techs., 200 F.3d at 803). Although we need not decide the precise meaning of “held together by a force-fitting connection” in order to decide whether to institute trial, we note (1) that, without some evidence to the contrary, a battery casing whose half-parts are “held together by” a particular condition must be a battery casing whose half-parts would no longer be held together if the condition were not present, and (2) that neither party has directed us to any evidence to the contrary. Accordingly, whatever a “force-fitting connection” is, a battery made in accordance with the teachings of the prior art is not a battery that is “held together by a force-fitting connection” unless that battery would cease to be held together in the absence of the “force-fitting connection.”” slip op. at 11

      “In fact, Petitioner’s argument appears to support the opposite conclusion. According to Petitioner, “barb fittings are known by POSAs to be particularly poorly suited to sterile and aseptic processing because they incorporate pockets where bacteria and contaminants may reside.” Id. at 46–47 (citing Ex. 1003 ¶ 96). This statement appears consistent with Maurer’s teaching. Indeed, Maurer teaches “it is advantageous if the design avoids the creation of cavities or pockets in which contaminated material can collect.” Ex. 1005, 14:16–18. This is especially important because, as Petitioner points out, Maurer envisions using its device “in pressure measurement in kidney dialysis machines.” Pet. 30 (citing Ex. 1005, Abstract, 14:6–20). Given Maurer’s goal to avoid contamination (see Ex. 1005, 1:24–31, 8:33–36, 9:50–56), and Petitioner’s acknowledgement that barb fittings are “particularly poorly suited to sterile and aseptic processing because they incorporate pockets where bacteria and contaminants may reside” (Pet. 46–47), we find Petitioner has not explained sufficiently why an ordinarily skilled artisan would have incorporated hose barbs into Maurer’s device.

      “it is used consistently throughout. First, in describing related prior art, the ’903 patent states that “[t]he through plug is constituted of an insulating material covering a sidewall of a through hole and a low electrical resistance metal material . . . in a columnar shape that is positioned so as to be surrounded by the insulating material and that serves as a conductive member.” Ex. 1001, 1:35–40. In describing its own drawings, reference numeral 15 consistently is used to refer to the “through plug.” Id. at 2:37– 52. Figures 1A and 1B “are views schematically showing the structure of a semiconductor device (semiconductor chip) according to an embodiment of the present invention.” Id. at 5:46–48, Figs. 1A, 1B. In these figures, reference numeral 15 refers to “[a] through plug.” Id. at 6:16. This through plug “is constituted of a columnar electric conductor 15a . . . and an insulation layer 15b . . . surrounding the electric conductor 15a.” Id. at 6:21–25. Similarly, reference numeral 15 refers to the “through plug” in Figures 1C, 2A, 2B, 3, 4, 5, 6, 7A, and 7B. Id. at 6:35–40, 7:10–38, 8:10– 17, 8:32–38, 8:65–9:43. Where it is referred to in these same parts of the ’903 patent, the conductive core is discussed as merely a portion of the through plug and is referred to by the reference numeral 15a. Id. Thus, the ’903 patent consistently defines the through plug as having two portions: both a conductive core and a surrounding insulation layer. This is true whether the patent is referring to either of its disclosed embodiments or the prior art. Based on this unambiguous usage, we determine that the ’903 patent defines the term “through plug” as including both a conductive core and a surrounding insulating layer. See Phillips, 415 F.3d at 1320–21 (“the specification ‘acts as a dictionary when it expressly defines terms used in the claims or when it defines terms by implication’” (quoting Vitronics Corp. v.

      “We are not persuaded that the Petition adequately identifies how Christensen teaches or suggests a through plug as that term is used in the ’903 patent. As noted above, the ’903 patent requires a through plug to have both a conductive core and a surrounding insulating layer. It is clear on the current record that Christensen’s “conductive stud” could correspond to the conductive portion of such a through plug. Ex. 1033, 4:66–5:1 (“the stud 34 may comprise any number of conductive materials”). But Petitioner does not show sufficiently that Christensen teaches or suggests the surrounding insulating layer necessary to turn the conductive core into a through plug. First, Petitioner does not allege that Christensen teaches or suggests such a layer. Pet. 33–34. Second, Christensen discloses the use of “conductive materials” and “material[s] which promote[] adhesion to the surrounding oxide such as titanium or titanium nitride.” Ex. 1033, 4:66–5:1, 5:15–20. None of these materials are identified by Christensen as insulators. Id. Accordingly, we are not persuaded on the current record that Petitioner has shown sufficiently that Christensen alone teaches or suggests the through plug of the challenged claims. b.

Specifically, Petitioner argues that “[t]o the extent [it is determined] that Christensen alone is not sufficient because the conductive stud 34 does not extend all the way through wafer 12, Christensen in view of Lin renders obvious a ‘through plug.’” Id. at 34. According to this argument, “Lin teaches a backside process for forming ‘a conductive plug through a silicon’ wafer and an insulation layer,” and it would have been obvious to form such a plug “from the backside of the wafer 12 below [Christensen’s] conductive stud 34,” such that the combination of the two structures would form a conductive path all the way through the structure of Christensen’s Figures 8B and 9. Id. at 34–35 (emphasis omitted). As with the argument based on Christensen alone, however, this argument does not show sufficiently that the combination of Christensen and Lin teaches or suggests a through plug that has both a conductive core and a surrounding insulating layer. Lin describes its structure as a “conductive plug” and does not describe any insulation surrounding that structure. Ex. 1054, 1:60–64, 3:2– 34, 4:23–32, Fig. 7. “The conductive plugs” of Lin “typically compris[e] metal,” which Lin does not describe as an insulator. Id. at 3:21–25. Nor does Petitioner allege the presence of a conductive core surrounded by insulation either in Lin itself or in the combination of Lin and Christensen. Pet. 34–36. Accordingly, we are not persuaded on the current record that Petitioner has shown sufficiently that the combination of Christensen and Lin teaches or suggests the through plug of the challenged claims.” slip op. at 9

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not found

      “An invention is not obvious just ‘because all of the elements that comprise the invention were known in the prior art.’” Broadcom Corp. v. Emulex Corp., 732 F.3d 1325, 1335 (Fed. Cir. 2013) (quoting Power-One, Inc. v. Artesyn Techs., Inc., 599 F.3d 1343, 1351 (Fed. Cir. 2010)). Instead, “a finding of obviousness at the time of invention requires a ‘plausible rational[e] as to why the prior art references would have worked together.’” Id. (quoting Power-One, 599 F.3d at 1352). This rationale requires “some articulated reasoning with some rational underpinning” to combine the known elements in the manner required in the claim at issue. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). “[I]t can be important to” include within this reasoning “a reason that would have prompted a person of ordinary skill in the relevant field to combine the elements in the way the claimed new invention does.” Id. Here, Petitioner offers two reasons to combine the teachings of Shim and Shirakawa. First, Petitioner argues that “Shim’s diffusion teachings would facilitate the formation of” Shirakawa’s collector layer. Pet. 65–66. On the present record, we do not find this reason sufficiently persuasive. Even though Shim does teach a way to make the n-GaAs that Shirakawa uses, Shirakawa teaches a different way to make the same material, and other prior-art references agree with Shirakawa. Ex. 1022, 1:34–40 (“silicon ions of a silicon layer formed on a GaAs substrate are diffused by means of ion-implantation method using little energy and annealing treatment”); Ex. 1005, 9:36–42 (first embodiment “collector layer” is “laminated on top of a semi-insulating GaAs substrate . . . by epitaxial growth process”), 12:47–48 (fourth embodiment made in same way as first embodiment); Ex. 1016, 8:7–19 (“a highly doped n type GaAs subcollector layer . . . [and other layers] are made to grow above a semiinsulating GaAs substrate . . . by a metal organic vapor phase epitaxial growth method”); Ex. 1025, 4:40–45 (teaching “[f]orming two flat epitaxial layers of gallium arsenide to obtain [a] collector,” including “a layer . . . of the n+ conductivity type and a layer . . . of the n -conductivity type” by “epitaxial growth . . . from the vapour phase or from the liquid phase”). The mere fact that Shim offers an alternative process does not, in the absence of a reason to adopt that alternative process, provide a reason for a person of ordinary skill in the art to make Shirakawa’s n-GaAs via Shim’s method rather than via Shirakawa’s own method. In addition, Patent Owner’s declarant, Dr. Peter Elenius, testifies that the ion implantation involved in Shim’s diffusion process would damage Shirakawa’s gallium arsenide in a way that would dissuade a person of ordinary skill in the art from using that process to produce the HBT of Shirakawa. Ex. 2001 ¶¶ 52–57. The other reason that Petitioner provides to combine the teachings of Shim and Shirakawa is that Shim’s diffusion “method us[es] little energy and annealing treatment.” Pet. 66 (quoting Ex. 1022, 1:34–40). Shim’s method is described as “diffus[ion] by means of ion-implantation method using little energy and annealing treatment,” which Shim distinguishes from earlier methods “widely used in the art,” which involved “ion-implantation . . . using high energy.” Ex. 1022, 1:12–40. Shim teaches that its lower-energy ion implantation does not suffer from the “problem” of the earlier method, “damaging of ohmic contacts of metal electrodes” due to the injection of “lots of impurity ions.” Id. at 1:17–22; see id. at 3:37–40 (“the manufacturing method of the present invention can prevent damage to be generated in ohmic contacts of source/drain electrodes due to ion-injecting of high density”). Thus, the lower energy of Shim’s process is a benefit of that process over earlier ion implantation processes, which use higher energy. Shim does not teach that its use of lower-energy ion implantation is an improvement over other processes, such as the epitaxial growth taught by Shirakawa and the other references cited by Petitioner. Thus, Petitioner does not explain sufficiently why lower energy would be a benefit of the Shim- Shirakawa combination over Shirakawa alone. Accordingly, we are not persuaded on the current record that Petitioner has shown sufficiently that a person of ordinary skill in the art would have had a reason to combine the teachings of Shirakawa and Shim to arrive at a combination that teaches or suggests the “diffusion layer patterns” of the challenged claims. slip op. at 15
