“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

At this time, Patent Owner does not dispute Petitioner’s proposed construction of “electrode section.” See generally Prelim. Resp.

“adhesion layer” is recited only in the challenged independent claims and in no other claims of the ’879 patent. See Ex. 1001, 13:45–16:65. And each of the independent claims recites “forming” an “adhesion layer” “on a back surface” of a “wafer.” Id. at 13:47–49, 13:54–56, 15:4–6, 15:45–47, 16:48– 50, 16:56–58. In view of this claim language, we construe the relevant claim language “forming an adhesion layer on a back surface of a wafer” as a whole, not just a single term “adhesion layer” in isolation from the rest of the claim language. See Anchor Wall Sys., Inc. v. Rockwood Retaining Walls, Inc., 340 F.3d 1298, 1311 (Fed. Cir. 2003) (“[T]he claim limitation, as a whole, [] must be considered in claim construction.”); United States v. Telectronics, Inc., 857 F.2d 778, 781 (Fed. Cir. 1988) (holding that district court’s interpretation of the term “avoid” without regard to the rest of the limitation was error); see also Lexion Med., LLC v. Northgate Techs., Inc., 641 F.3d 1352, 1356 (Fed. Cir. 2011) (“[T]he context of the surrounding words of the claim also must be considered in determining the ordinary and customary meaning of those terms.”); IGT v. Bally Gaming Int’l, Inc., 659 F.3d 1109, 1117 (Fed. Cir. 2011) (“We caution that claim language must be construed in the context of the claim in which it appears. Extracting a single word from a claim divorced from the surrounding limitations can lead construction astray.” (emphasis added)); Hockerson-Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed. Cir. 1999) (“Proper claim construction . . . demands interpretation of the entire claim in context, not a single element in isolation.”). Considering the claim language, the Oxford English Dictionary defines “form” as “[t]o construct, frame; to make, bring into existence, produce.”4 Thus, the plain meaning of the claim term to “form[] an adhesion layer on a back surface of a wafer” is “to construct or make an adhesion layer on a back surface of a wafer.” At this time, we do not perceive anything in the claim language that requires any specific method to construct an adhesion layer on a wafer surface. Thus, at least based on the claim language, we are not persuaded at this time that the challenged claims require adhering a pre-formed adhesion layer to a surface of a wafer, as Patent Owner contends. Citing the Specification of the ’879 patent, Patent Owner contends that the recited “adhesion layer” is “a pre-formed layer that is adhered” to the back surface of a wafer because the ’879 patent describes that the “[second semiconductor’s] back surface is adhered to the thermo-compression sheet 6.” Prelim. Resp. 12 (citing Ex. 1001, 6:48–52). The language cited by Patent Owner comes from the ’879 patent’s description of Figure 1, which shows “a semiconductor device in accordance with the first embodiment” of the ’879 patent. Ex. 1001, 5:34–36 (emphasis added), 6:37– 52. A particular embodiment appearing in the written description is generally not incorporated into a claim if the claim language is broader than the embodiment. SuperGuide Corp. v.

“Considering the claim language of claim 3 as a whole, see Hockerson- Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed. Cir. 1999) (“Proper claim construction . . . demands interpretation of the entire claim in context, not a single element in isolation.”), we agree with Petitioner that claim 3 does not recite when or how the “adhesion layer” is “adhered to [the first semiconductor chip’s] back surface.” Patent Owner appears to argue that the “first semiconductor chip” with “an adhesion layer adhered to its back surface,” as recited in claim 3, must have been created “in advance,” e.g., by a wafer-level fabrication process, before the chip is mounted in the recited semiconductor device. Patent Owner argues that the patentee recognized that applying a paste or thermo-compression sheet on individual chips during packaging (i.e., mounting of the chips during packaging) caused the “overflow” and “gap” problems. Sur-reply 2 (citing Ex. 1001, 2:16–24, 2:44–46). According to Patent Owner, “the patentee further recognized that merely switching to a pre-formed solid sheet alone would not solve the problem” because using a thermo-compression sheet on an individual chip for mounting during packaging “results in the same problem as using an adhesive due to the inability to place the chip accurately on the thermo-compression sheet.” Id. at 2–3 (citing Ex. 1001, 2:49–56). Thus, Patent Owner argues the ’806 patent proposes a two-fold solution: “Use a preformed solid sheet and attach that sheet to the back surface of the wafer first” during the wafer fabrication process “before cutting and placing the chip” in a multichip package. Id. at 3 (underlined emphases added). Patent Owner asserts, therefore, “a first semiconductor chip having . . . an adhesion layer adhered to its back surface,” as recited in claim 3, must have a pre-formed adhesion layer adhered to its back surface “in advance” before mounting in a multichip package, such as a solid thermo-compression sheet applied to the backside of a wafer during wafer-level fabrication processing before the chips are produced by dicing. Prelim. Resp. 13–14; Sur-reply 2–3. We note, however, that claim 3 does not recite a “wafer,” placing “an adhesion layer on a back surface of a wafer,” or producing semiconductor chips by dicing or cutting the wafer. See Ex. 1001, 14:14–32. Nor does the claim recite any limitation indicating when or how an “adhesion layer” is “adhered to [the first semiconductor chip’s] back surface.” Thus, at least based on the claim language, claim 3 does not require the recited semiconductor chips with an adhesion layer to have been produced “in advance” before being used for mounting in the recited semiconductor device.

“We agree with Patent Owner that separate structures are required. The strongest evidence for this requirement is the claim language itself, which plainly recites two different elements: “a pressurization unit” for inside air and “a compressor” for outside air. The separate naming of two elements in the claim strongly implies that they are not one and the same structure. Becton, Dickinson & Co. v. Tyco Healthcare Group, LP, 616 F.3d 1249, 1254 (Fed. Cir. 2010) (“Where a claim lists elements separately, the clear implication of the claim language is that those elements are distinct components of the patented invention.” (punctuation omitted) (quoting Gaus v.

“At most, the similarities between each pair of references establish, as a threshold matter, that they would have been considered by a POSITA. See K-Tec, Inc. v. Vita-Mix, Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either in the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). But the asserted similarities alone are not sufficient to show that a POSITA would have had a reason to combine the teachings in the manner described in the challenged claims. Personal Web Techs., LLC v. Apple, Inc., 848 F.3d 987, 994 (Fed. Cir. 2017) (It is not enough that a skilled artisan, once presented with two references, would have understood that they could be combined; Petitioner needs to establish a motivation to pick out the two references and combine them to arrive at the claimed invention.). Next, Petitioner asserts that a POSITA would have been motivated to modify the glass tempering furnace of each base reference “to temper low-E glass more quickly and efficiently.” Pet. 24, 27, 30 (citing Ex. 1003 ¶¶ 82, 90, 98). As discussed below, Petitioner fails to show a sufficient logical connection between the asserted motivation and the proposed modification(s) of the base references. Stated differently, Petitioner fails to show a sufficient reason why a POSITA would have made the modifications necessary to bridge the gap between the prior art and the claimed subject matter. We discuss each pair of references more specifically below.” slip op. at 18

For purposes of the Preliminary Response, Patent Owner does not dispute Petitioner’s definition of a POSITA. Prelim. Resp. 27. For purposes of this Decision, we apply Petitioner’s definition of a POSITA, which is consistent with the scope and content of the ’911 Patent and the asserted prior art.” slip op. at 7

Pet. 9–10 (citing Ex. 1002 ¶ 36). Patent Owner states that it “does not agree that Petitioner’s proposed level of skill in the art accurately reflects the level of ordinary skill in the art as of the priority date . . . . But regardless of what level of skill is applied, the Petition does not show a reasonable likelihood to prevail.” Prelim. Resp. 10.

Petitioner’s argument appears to be premised on the understanding that any point at which the path contacts a “surface suitable for anchoring the part” is the claimed “anchor point.” The ’543 patent, however, describes an “anchor point” as something more than just any point to which a part of the path is affixed.” slip op. at 11
