“Patent Owner asserts that the preamble of independent claim 1 reciting “a deodorant stick” is limiting” as it provides antecedent basis for certain other claim elements, specifically, for the recitation of “said stick being free of an aluminum salt” and “said stick” having a particular hardness range. PO Resp. 8–9. We agree. Petitioner does not provide argument to the contrary. See, e.g., Pet. 30 (arguing that Lesniak discloses a deodorant stick in the form of an antiperspirant stick).

“We have considered Patent Owner’s arguments but find, on this record, Petitioner to have the better position. In particular, we are persuaded that a POSA would have been motivated to add magnesium hydroxide to Lesniak’s compositions because Phinney teaches that: (i) zinc oxide has “low activity” as a “deodorant agent”; (ii) magnesium hydroxide is “an effective synergistic effects, hence motivating a POSA to add magnesium hydroxide to Lesniak’s zinc oxide deodorants. Ex. 1004, 1:13- 3:16, 5:61-67. Reply 10; see also PO Resp. 25–26 (arguing that a POSA would have found it obvious to add magnesium hydroxide to the composition of Lesniak because zinc oxide is not a particularly efficacious antimicrobial in deodorants when used alone, whereas magnesium hydroxide is an effective deodorant). We acknowledge that Phinney suggests mixing zinc oxide with water in order to convert zinc oxide to zinc hydroxide. See, e.g., Ex. 1004, 1:17– 19 (“It was also found that a mixture of the hydroxides of zinc and magnesium could provide long lasting protection against odour due to perspiration.”). The evidence of record, however, shows that both magnesium hydroxide and zinc oxide were known options for deodorant antimicrobials, and claim 1 does not require a minimal level of effectiveness such that the combination of magnesium hydroxide and zinc oxide would need to outperform any other combination including the mixture of zinc and magnesium hydroxides. See In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (“Our case law does not require that a particular combination must be the preferred, or the most desirable, combination[.]”). Here, we also credit the testimony of Dr. Michniak-Kohn that “POSA would understand that the water-based vs. anhydrous distinction is not relevant, as a POSA would understand that magnesium hydroxide would still function as an antimicrobial in anhydrous compositions such as those disclosed by Lesniak.” Ex. 1086 ¶ 9 (citing Ex. 1072, 1-2, 5 (disclosing deodorants without added water and with zinc oxide and/or magnesium hydroxide)).

“teaches baking soda as an effective ingredient in a deodorant. Ex. 1005, 131–33. Baking soda is also known to cause irritation that may motivate some to remove it from deodorants. See Ex. 2011 ¶ 109–110. Thus, the specific set of advantages and disadvantages for using baking soda in a deodorant was known to a person of skill in the art. On this record, the inclusion or exclusion of baking soda presents no unexpected result and the evidence of record establishes that it would have been an obvious matter of design choice within the skill of the art to balance the advantages and disadvantages associated therewith. See Medichem, S. A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed.

“(TACs) extending vertically through the dielectric structure” recited in claim element [8.G] encompasses multiple TACs, each extending through a separate, different dielectric structure, while Patent Owner argues that the phrase requires that the plurality of TACs (i.e., at least two TACs) must extend through the same dielectric structure. See, e.g., Pet. 49–50; PO Resp. 18–21; Reply 2–4. In our Decision on Institution, we preliminarily construed this phrase to require that more than one (i.e., a plurality) TAC in the TAC region extends vertically through a single dielectric structure. See Inst. Dec. 17. Based upon a full record, we construe this term of claim element [8.G.iii] (i.e., “ . . . a through array contact (TAC) region formed between the first and second channel regions, wherein the TAC region comprises a plurality of through array contacts (TACs) extending vertically through the dielectric structure”) according to its plain language to require that a plurality (i.e., more than one) of TACs must extend vertically through a (i.e., at least one) dielectric structure. Under this construction, the plurality of TACs may extend through more than one dielectric structure, but the plurality of TACs must extend through at least one dielectric structure. The plain language of the claim is not satisfied if each TAC extends through a separate dielectric structure because, in this scenario, there is not a plurality of TACs that extend through a dielectric structure.” slip op. at 10

“Resp. 31–33. Patent Owner persuasively explains, with supporting testimony by Dr. Yang, that these regions containing the interconnects and peripheral circuitry would prevent repeating the layout in the hd1 direction because the interconnects and peripheral circuitry would be located in the same region that Petitioner proposes adding the additional memory plane. Id. (citing Ex. 2004 ¶ 72). Patent Owner further persuasively explains that Toyama teaches repeating the layout in the hd2 direction, not the hd1 direction, because of the location of its interconnects and peripheral circuitry, which prevents repeating the structure in the hd1 direction. See id. at 34 (citing Ex. 1005, Figures 17E, 17F). Patent Owner persuasively explains that Toyama Figure 17F (which is an alternate view of the structure shown in Figure 17E) shows that the memory array has interconnects and driver circuits on at least the left side, which means that in a modification adding additional planes, each plane would necessarily include these interconnects and driver circuitry on the left side. Id. at 35 (citing Ex. 2004 ¶ 75).

“We are persuaded by Petitioner that the lower volume of Toyama’s dielectric fill portion teaches the isolation structure and the upper volume of Toyama’s dielectric fill portion teaches the dielectric structure. First, the structure may be the same material; i.e., SiO2. Ex. 1001, 10:37–40 (isolation structure 233 filled with SiO2), 10:46–47 (dielectric structure can include SiO2, and can include the same material as dielectric layer 230), 10:12–14 (dielectric layer 230 is formed of SiO2). Second, the ’378 patent indicates that the dielectric structure may be “aligned to” and “in contact with” the isolation structure. Id. at 10:30–36. Thus, the two structures of the ’378 patent may appear as two aligned and contacting structures; e.g., a single column of the same material. Third, the ’378 patent specification describes that the dielectric structure and a top portion of the isolation structure may be formed in the same deposition step. When etching the opening 600 that is to be filled with dielectric structure 232, “opening 600 may extend partially into STI structure 233;” i.e., “the etch process used to form opening 600 may also remove (recess) portion of the top surface of STI structure 233.” Id. at 15:12–20; Fig. 6. Then, “opening 600 can be filled with a dielectric layer 702,” which may be the same SiO2 material as the isolation structure, and “[a]s a result, dielectric structure 232 is formed.” Id. at 15:42–54. Thus, the ’378 patent describes a dielectric structure that partially replaces or re-forms, with the same material, its isolation structure. The ’378 patent does not mention whether this results in a dielectric structure that extends into the isolation structure or an isolation structure re-filled to its original height, and it would not appear to matter because both structures may be composed of the same material. The ’378 patent’s indifference to the exact boundary between dielectric structure 232 and isolation structure 233 during formation from the same material indicates that these structures need not be taught by distinct elements. applicable only if the ’378 patent describes that the isolation region and dielectric structure were formed as a single unitary structure.

This passage suggests that [the structures] could be formed as an integral structure in the first instance”). Retractable Techs. looks to whether the specification suggests that the claim terms require separate structures. Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1232 (Fed. Cir. 2011). Patent Owner’s focus on whether the claimed structures were disclosed as being separately formed disregards the issue of whether the separately claimed structures require specific methods of forming those structures. Here, as in Retractable Techs. and Powell, the Specification does not indicate any particular structure or function for the structures that results from their separate steps of deposition. Thus, as held in Retractable Techs. and Powell, the two portions of Toyama “need not be two separate parts” to teach two separate claim limitations. Retractable Techs., 635 F.3d at 1303–04. Consequently, we determine that the claim language does not support a requirement that these structures be separate and distinct. Patent Owner’s further arguments are not availing.

Patent Owner relies on multiple embodiments, only one of which describes a substrate “with” an isolation structure. PO Resp. 21 (citing Ex. 1001, 22:27–28). For example, one of Patent Owner’s cited embodiments recites “on” an isolation region, but Patent Owner specifically argues that the “on” embodiment does not apply to the claimed “with” embodiment. Id. at 22 (denying that “the ‘with’ relationship encompasse[s] the ‘on’ relationship”). Only one of the embodiments cited is clearly within the scope of the “with” claim language, and that embodiment describes no more than the claim language itself. Ex. 1001, 22:27–28. Moreover, Figure 2, cited by Patent Owner, is an illustration “according to some embodiments,” but is not described as depicting all embodiments. Ex. 1001, 3:35–36. These other embodiments need not be included in claim 15’s “with” language because other claims (not at issue in this proceeding) specifically recite language from other embodiments. Ex. 1001, 23:20–21 (“a dielectric structure on an isolation region of the substrate”), 23:58 (“forming an isolation structure on a substrate”). Thus, the specification of the ’378 patent does not limit “a substrate with an isolation structure” in claim 15 to “part of” an isolation structure, such as in a shallow region or other partial-depth portion of the substrate.

We do not agree with Patent Owner that Retractable Techs. is applicable only if the ’378 patent describes that the isolation region and dielectric structure were formed as a single unitary structure. PO Resp. 50; PO Sur-reply 9. Retractable Techs. focuses on whether the two elements at issue “could be formed as an integral structure in the first instance,” not whether they were formed integrally. Retractable Techs., 653 F.3d at 1304. (“The specifications further disclose a method to couple the two structures . . . to allow some diffusion or insipient melting to occur where they touch . . . . This passage suggests that [the structures] could be formed as an integral structure in the first instance”). Retractable Techs. looks to whether the specification suggests that the claim terms require separate structures. Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1232 (Fed. Cir. 2011). Patent Owner’s focus on whether the claimed structures were disclosed as being separately formed disregards the issue of whether the separately claimed structures require specific methods of forming those structures. Here, as in Retractable Techs. and Powell, the Specification does not indicate any particular structure or function for the structures that results from their separate steps of deposition. Thus, as held in Retractable Techs. and Powell, the two portions of Toyama “need not be two separate parts” to teach two separate claim limitations. Retractable Techs., 635 F.3d at 1303– 04. Consequently, we determine that the claim language does not support a requirement that these structures be separate and distinct.” slip op. at 32

“Dr. Papanikolopoulos’s testimony that Kuwata teaches away from modifying its camera 22 to access an external server (such as Fisher’s Internet-enabled external data source) by stressing advantages of a self-contained camera-printer pair without external dependencies. See PO Resp. 15–16, 26–28 (citing Ex. 1005 ¶¶ 75, 77); Ex. 2001 ¶¶ 61–64. The cited disclosures in Kuwata simply do not discuss any advantages arising from a self-contained camera-printer pair without external dependencies, or any disadvantages arising from connecting camera 22 to an Internet server. See Ex. 1005 ¶¶ 75, 77. The cited disclosures instead tout the advantages arising from a camera manufacturer (rather than an end user photographer) specifying the image output control information CI for a specific camera-printer pairing, to reduce differences between an image as confirmed by the end user on the camera’s display and the image outputted by the printer. See id. That advantage, however, has nothing to do with whether camera 22 may or may not communicate with an Internet server. Indeed, rather than being self-contained as Patent Owner and Dr. Papanikolopoulos would have it, we find Kuwata’s camera 22 includes an I/O port for wired or wireless communication to transmit the camera’s image files GF / 10 to various printers 24 and various personal computers (PCs). See Ex. 1005, Fig. 4, ¶¶ 81, 85; Ex. 1003 ¶ 84; Pet. 14. Thus, Kuwata allows for and does not discourage communication between camera 22 and an Internet server such as Fisher’s external data source. In particular, Kuwata does not detract from the benefits of updating image output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Moreover, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶¶ 42, 55. That teaching in Fisher dovetails with Kuwata’s disclosure concerning camera manufacturers optimizing their cameras with various different printers, supporting Petitioner’s combination.

“articulated a reason why a person of ordinary skill in the art would have combined the teachings of Sudre, Lee, and Penven. Prelim. Resp. 60–63. 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. Teleflex Inc., 550 U.S. 398, 418 (2007).

“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.
