Petitioner discusses the terms a “data line having a broad-width portion” and a “scanning line having a broad-width portion” recited in claim 1, as well as a “data line having a broad portion” and a “scanning line having a broad-width portion” recited in claim 2. Petitioner cites the ’079 patent for “offering a lexicographic definition of the term ‘broad width’” to support the plain meaning interpretation of the terms “‘broad-width portion’ and ‘broad portion’ as a portion that is broader than another portion of the subject element.” Pet. 16. Patent Owner does not provide arguments directed specifically to Petitioner’s proposed claim constructions. See Prelim. Resp. 10–11. Taking account of the information presented, we determine that no claim term requires express construction for purposes of deciding whether to institute review. Compare Pet. 16 (addressing issues of claim construction, citing the ’079 patent for supporting the plain and ordinary meaning of “broad-width portion” and “broad portion” without demonstrating that an express construction is necessary to resolve whether to institute review), with Prelim.

“Id. (emphasis added). Sato ¶ 26 is entirely silent on scan lines and clearly links the cited benefits to “this arrangement” of “data lines composed of an Al film.” Id. Importantly, Petitioner does not connect Sato’s disclosure, relating to benefits associated with a data line arrangement, to any particular arrangement of scan lines. Sato ¶ 28 is equally deficient. Sato ¶ 28 also discusses benefits of utilizing a specific “arrangement,” namely, “capacitance lines formed of [a] metal film.” Id. ¶ 28. [0028] With this arrangement, the provision of the function as the shading layer with the capacitance lines formed of the metal film, the polysilicon film, or the like, in addition to the function as the wiring, as well as the provision of the function as the light absorption layer with the capacitance electrodes formed of the polysilicon film, or the like, in addition to the function as electrodes, prevents the laminated structure from becoming complex by additionally forming a dedicated shading layer and a dedicated light absorption layer. Accordingly, this arrangement is very advantageous by simply arranging the electro-optical device, and simplifies a manufacturing process thereof. Id. (emphasis added). Here again, Sato ¶ 28 is entirely silent on scan lines and clearly links the cited benefits to “this arrangement” of “capacitance lines formed of metal film.” Id. Petitioner does not bridge the gap in its rationale to combine by attempting to explain why an ordinarily skilled artisan would have extrapolated benefits, pertaining to an arrangement of capacitance lines, to a similar arrangement of scan lines. Petitioner’s witness, Dr. Flasck, provides no further insight as to how or why Sato ¶¶ 26 and 28 would have been understood to apply to scan lines. Dr. Flasck’s comments on Sato ¶¶ 26 and 28 merely repeat, nearly verbatim, the Petition’s conclusory contentions.

The dispute between the parties on this issue is largely one of claim construction: should the term “wiring line” in claim 7 be construed broadly enough to encompass a collection of lines separated by a sample hold circuit? In order to determine that Fujikawa discloses or teaches the recited wiring lines, we would need to answer this question in the affirmative. Yet, as discussed above, neither party proposes construing “wiring line,” or any other term used in the claims of the ’606 patent. Pet. 18; Prelim. Resp. 7. The failure to argue for and sufficiently support a broad construction of the term “wiring line” means that Petitioner does not show sufficiently, for purposes of supporting institution of review, that Fujikawa discloses or teaches the “wiring line” limitation of claim 7. b) Conclusion Regarding Claim 7 Based on the record presented, we determine that Petitioner has not shown that there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 7 is unpatentable as anticipated by or obvious in view of Fujikawa.” slip op. at 11

“We conclude the preliminary record supports, sufficiently to justify institution, Petitioner’s contention that a person of ordinary skill in the art would have been motivated to configure Reiner’s gate/scanning driver 63 to include the ESD protection network structure illustrated in Figure 5. First, we agree with Petitioner’s position that Reiner discloses both of its display drivers 61 and 63 would benefit from ESD protection. That is, Reiner describes display drivers 61 and 63 as “typical example[s]” of integrated circuit devices that can benefit from utilizing Reiner’s bump bridge technology for providing ESD protection, due to the large number of parallel output lines that must cross power supply lines. See Ex. 1005, 4:15–16, 9:11–20 (describing Fig. 4), 12:4–5. Thus, based on this preliminary record, we disagree with Patent Owner’s position that Petitioner mischaracterizes Reiner’s teachings in this regard. Second, based on the preliminary record, Dr. Murphy’s testimony that the ESD protection network structure of Reiner’s Figure 5 would be suitable for implementing in Reiner’s gate/scanning driver 63 due to similarities between the two drivers is supported by the evidence sufficiently to justify institution. See Ex. 1003 ¶¶ 104–105, 111–120. A first similarity is Reiner’s indication that both display drivers 61 and 63 “have areas where the output or input metal lines have to cross power supply lines” Vdd and Vss. Ex. 1005, 9:11–20, 12:4–5, Fig. 3 (illustrating exemplary integrated circuit device 30 powered by supply voltages Vdd and Vss). A second similarity is Dr. Murphy’s testimony that, at least in some embodiments of Reiner’s gate/scanning driver 63, “each of the [scan] lines being driven will have its own semiconductor units . . . [that] drive that particular line,” akin to the individual output devices 70 and source lines 67 of Figure 5. Ex. 1003 ¶¶ 113, 117; see also Prelim. Resp. 21–22 (arguing “Reiner [discloses] that the gate driver integrated circuit comprises individual gate drivers” and “a POSITA would understand that individual gate/scan line drivers are coupled to one another”). These similarities between Reiner’s display drivers 61 and 63 support Dr. Murphy’s conclusion that Reiner’s bump bridge technology for providing ESD protection could and would have been implemented in Reiner’s gate/scanning driver 63 in the same fashion as illustrated in Figure 5 for Reiner’s source/data driver module 61. We appreciate, as Dr. Schubert testifies, that the individual circuits in gate/scanning driver 63 will drive their respective gate/scan lines 68 in different ways than the individual output devices 70 in source/data driver module 61 will drive their respective source/data lines 67. See Ex. 2001 ¶¶ 55–59. Nonetheless, based on the present record, we conclude such differences in the signal outputs of Reiner’s display drivers 61 and 63 have little to do with the benefits of configuring the power inputs of the display drivers to protect the individual circuits from electrostatic discharge events, or how to do so.” slip op. at 35

“‘run[ning] generally parallel to the lateral extent of a semiconductor material or semiconductor carrier’” and that “[t]he ’481 patent . . . describes a device that ‘has a lateral drift path.’” Pet. 24 (quoting Ex. 1001, 3:14–18, 4:37–38). Patent Owner directs us to a statement in the prosecution history that “[a] lateral transistor is a transistor in which current flows across ‘in the direction parallel to’ the device surface,” as opposed to “a vertical transistor,” in which “[c]urrent ‘flows in the direction normal to’ the device surface.” Prelim. Resp. 8 (quoting Ex. 1002, 33–34). Thus, the parties generally agree that a lateral transistor is a transistor in which current flows in a direction parallel to the surface of the transistor. Petitioner argues that Nega teaches or suggests a transistor in which current flows parallel to the surface because Nega’s source, gate, and drain electrodes “are spread laterally in a lateral drift path, instead of vertically stacked.” Pet. 24–25 (citing Ex. 1005, Fig. 2). Patent Owner argues to the contrary that the placement of source, gate, and drain electrodes in the same lateral plane, rather than in a vertical stack, does not necessarily indicate that the current flow within the transistor is parallel to the surface. Prelim. Resp. 47–48 (citing Ex. 2002, 7–8, Figs. 1.7a, 1.7c). According to Patent Owner, transistors with electrodes in the same horizontal plane can have either lateral or vertical current flow. Id. Thus, Patent Owner argues, the lateral placement of the source, gate, and drain electrodes in Nega does not mean that Nega teaches or suggests a lateral transistor. On the present record, we agree with Patent Owner that Petitioner has not shown sufficiently that Nega teaches a transistor in which current flows in a direction parallel to the surface, rather than in a direction normal to the surface. Transistors with current flow in either direction can have electrodes located on a common horizontal plane, with the direction of the current flow depending on the configuration of doped semiconductor regions located below the electrodes. Ex. 2002, Figs. 1.7a, 1.7c.

Based on the current record, we are not persuaded that Petitioner sufficiently shows that Park teaches the claimed “dummy source structure.” Petitioner’s reasoning with respect to common source lines 144 is based on Petitioner’s proposed claim construction, which we do not adopt for purposes of this Decision. See Pet. 54–60. Park distinguishes common source lines 144 that are included on the memory cell structure with first and second channel structures 120a and 120b, and gate lines 134 from dummy source lines 146 that are included on the dummy region with second structure 140 and third channel structure 120c that “may not serve as a channel of the memory cell, and may merely serve as a supporting pillar of the second structure 140.” Ex. 1005, 6:9–11, 8:1–2, 8:57–60. That common source lines 144 are disposed on the cell region of the substrate while dummy source lines 146 are disposed on the dummy region alone at least indicates that the common source lines 144 and dummy source lines 146 may not operate in the same way or serve the same purpose.

See, e.g., Ex. 1001, 3:65–67 (“a layer can be located between any pair of horizontal planes between, or at, a top surface and a bottom surface of the continuous structure”), 4:56–57 (“dummy channel holes are formed between adjacent GLSs”), 7:12–15 (“one or more dummy channel structures may be located between two dummy source structures, and vice versa”), 7:16–17 (“at least one dummy source structure may be located between two staircase contacts”), 9:63–64 (“an insulation layer (not shown) is formed between substrate 102 and memory stack 160), 17:42–44 (“at least one dummy source structure is located between the first and second staircase contacts”). In contrast, the Specification uses “surrounding” to indicate an object in the middle of more than two structures. See, e.g., id. at 6:38–41 (“multiple dummy source structures, such as the four dummy source structures indicated by a diamond shape 146, may surround a staircase contact, such as staircase contact 122”), 6:60–63 (“A plurality of dummy channel structures, such as the four dummy channel structures indicated by square shape 148, may surround a staircase contact.”), 7:31–34 (“four dummy channel structures indicated by dashed-line square shape 142 are surrounded by eight dummy source structures indicated by an octagon 144”), 7:38–40 (“one dummy channel structure indicated by dashed-line square 147 is surrounded by four dummy source structures indicated by a diamond 149”), 17:61–62 (“at least one dummy channel structure is surrounded by at least four dummy source structures”), 17:63–64 (“at least two dummy channel structures are surrounded by at least six dummy source structures”), 17:65–67 (“at least four dummy channel structures are surrounded by at least eight dummy source structures”). That claim 15 recites “wherein at least one dummy channel structure is surrounded by at least four dummy source structures” and claim 14, from which claim 15 depends, recites “wherein a subset of the dummy channel structures is surrounded by the plurality of dummy source structures,” does not require a different result. While we agree with Petitioner that the doctrine of claim differentiation may “impl[y] that ‘surrounded’ in independent claim 14 covers implementations in which fewer than four dummy source structures surround a single dummy channel structure,” that does not require that “surround” encompasses a dummy channel structure between two dummy source structures. Pet. 33 (citing Ex. 1001, claim 15 (21:9–11)). For example, three dummy source structures surrounding one dummy source structure could satisfy claim 14 but not claim 15 (“at least four dummy source structures”). Accordingly, we determine that “surrounding” in claim 1 of the ’872 patent does not encompass structures on only two sides of an object. We need not provide an explicit construction of “surrounding,” as terms in controversy need to be construed only to the extent necessary to resolve the controversy.

“the proceeding that a POSITA would have modified Toyama to provide a multi-plane flash memory device that could issue a read command on multiple planes simultaneously, thereby improving the throughput of program operations and the performance of NAND based systems. Id. at 68–75 (citing, inter alia, Ex. 1023, 144; Ex. 1014, 308, 313–314). Petitioner also provides sufficient arguments and evidence that this solution was quite common because power issues related to this kind of solution are still manageable inside the chip and optimized versus two separate NAND devices active at the same time. Id. at 75 (citing Ex. 1025, 44–45, 171; Ex. 1003 ¶¶ 141–147); see also Ex. 1003 ¶¶ 141–147 (citing, inter alia, Ex. 1023, 144, 247, Fig. 6.1; Ex. 1024, 13:37–44; Ex. 1014, 308, 313–314; Ex. 1025, 42, 44–45, 171). POSITA would have had a reasonable expectation of success in implementing multiple planes of Toyama’s First Exemplary Structure in the hd1 direction because NAND devices having multiple planes existed for many years before the priority date of the ’806 patent and that implementation of such a structure would have been straightforward as it merely applies a known technique (implementing multiple planes of NAND flash memory array) to a known device (Toyama’s first exemplary structure) to yield predictable results (a NAND flash device with improved performance).

Accordingly, at this stage of the proceeding, Petitioner sufficiently shows that a POSITA would have had reason to modify Toyama’s First Exemplary Structure to repeat portions of the device in the hd1 direction in order, inter alia, to improve performance of the device and would have done so with a reasonable expectation of success, and that such a modification results in a TAC region formed between first and second channel regions as required by claim element [8.G], notwithstanding Patent Owner’s arguments to the contrary, which raise issues best resolved on a full record.” slip op. at 28
