“Paper 34, 1 (requesting “Director Review of the Director’s August 22, 2025 Decision Referring the Petition to the Board (‘Referral Decision’)”). Patent Owner argued that institution of IPR2025-00687 and IPR2025-00688 “should be discretionarily denied.” Id. at 5. Petitioner opposed. Paper 37. The Director granted review and found that “granting institution of two petitions that each challenge the same claims of the ’370 patent and ’218 patent 2” was an “abuse[] of discretion.” Paper 40, 1. The Director remanded the cases “to the Board panel to determine which of the two petitions challenging each of the ’370 and ’218 patents to institute.” Id. at 3. Pursuant to the Director’s instruction that we choose only one of the two petitions challenging the ’370 patent to institute, and for the reasons set forth below, we choose to institute review of the ’370 patent in this Petition, and not in IPR2025-00688.” slip op. at 3

“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). In particular, Petitioner directs us to Sudre’s teaching of “a method for manufacturing PMC,” to Sudre’s lack of teaching of “specific parameters, such as warp thread size and spacing” to satisfy the “particular requirements” of its fabric. Pet. 79 (citing Ex. 1003 ¶¶ 248–250; Ex. 1004, 1:2–5, 6:14–17).

“336. The applicant explained that not all combinations of shrink films and light blocking materials are recyclable. Id. at 335. The applicant explained that films can be compatible with PET recycling in two ways, (1) the film can float in water and be separated from PET that sinks in water or (2) the PET films crystallize and “can be recovered with the PET stream.” Id. at 336 (citing “A Resource Document by the Association of Plastic Recyclers (APR)”) (found at Ex. 1002, 323–332) (emphasis omitted). The applicant explained that “removing the label before or during the recycling process is not evidence of the recyclability of the label” and that “[r]emoving the label during the recycling process is not equivalent to actually recycling the label.” Id. at 335. As such, a POSITA reading the prosecution history would understand that a label is not recyclable with a PET container, as recited by the independent claims, by removing the label from the PET recycle stream before or during the recycling process.” slip op. at 10

“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“(c) Analysis We have reviewed and considered both parties’ arguments and evidence and determine that Petitioner has sufficiently shown that Kim discloses or suggests the limitations of claim 1. We disagree with Patent an “island” shaped landing pad that is surrounded on all four sides by auxiliary layer 122. Based on the present record, we do not understand the Petition to rely solely on the “island” landing pad embodiment of Kim because the Petition also refers to an embodiment in Kim that is not island shaped. See, e.g., Pet. 34–35 (citing, inter alia, Ex. 1005, Fig. 5). In this embodiment, the sides of protrusion pad PAD_P are “coplanar” with 2 of the edges of PAD_B (i.e., E3, E4). See, e.g., Ex. 1005, Fig. 5. We understand that, in this embodiment, PAD_P is not an “island” landing pad because the auxiliary layer would not surround the landing pad on the sides of the landing pad coplanar to edges E3 and E4. See, e.g., Ex. 1005, Fig. 5. Thus, in this embodiment, the asserted first material layer (i.e., insulating layer 110 and the portion of the auxiliary layer to the left of the landing pad) would not form one structure all the way around PAD_P, as contended by Patent Owner. Prelim. Resp. 21 (citing Ex. 2006 ¶ 61). Rather, the asserted first material layer would end as depicted by Petitioner. See, e.g., Pet. 34–35 (citing Ex. 1005, Fig. 4B).” slip op. at 18

“B. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art (“POSITA”) at the critical time “would have had a bachelor of science degree in electrical engineering or a similar discipline, along with 2-3 years of professional experience working with (e.g., researching, designing, or teaching) monolithic 3D structures and NAND flash memory devices, or an equivalent level of skill, knowledge, and experience (e.g., an advanced degree may replace some of the professional experience).” Pet. 26 (citing Ex. 1003 ¶42).

“Patent Owner argues that Kim’s Figure 22A shows “[a gate stack] 161 to 168 (tan) disposed below a dielectric layer 111-118 (light purple)” rather than “disposing a sacrificial layer over a dielectric layer” as claimed. Prelim. Resp. 12. Petitioner’s assertions are supported by its assertions based upon Kim’s alternate embodiment, in which the bottom-most step has a lower dielectric layer 111 on which the gate stack 161 is disposed. Compare Ex. 1005, Fig. 22A (representing the embodiment of the dielectric layer at the top surface) with Pet. 37 (Petitioner’s altered Figure 17A representing the embodiment in which the dielectric layer is at the top surface). It is true that the gate stack 161 may also be below dielectric layer 112; however, Patent Owner’s alternate manner of viewing the arrangement of layers does not contradict Petitioner’s equally valid description based upon Kim’s dual embodiments. Petitioner sufficiently shows that Kim’s lower steps (or even a single step) teaches deposition of a sacrificial layer (e.g., SC1) over a dielectric layer (e.g., 111). Pet. 36–37. Consequently, we agree that Petitioner has sufficiently shown Kim to teach or suggest limitations [1.PRE]9 and [1.A].10” slip op. at 9
