“understanding that the claim term “from bottom to top” refers to the vertical arrangement of word lines in the memory portions from bottom to top and not from source end to drain end, as asserted by Petitioner. Inst. Dec. 17. In other words, the claim terms describing the first and second portions having word lines “from top to bottom” refer to the relative vertical location of the word lines within the memory portions and not to location of the word lines relative to the source or drain. Our construction is based on the plain and ordinary meaning of the express language of the independent claims, which states that the second memory portion is formed either above or below the first memory portion. The forming of one memory portion above or below another portion establishes a top and bottom in relation to those portions. For example, claim 5 is directed to a “program method of memory” that requires a second portion formed above the first portion. A second memory portion that is formed above a first memory portion is on top relative to the first portion. Similarly, claims 1 and 1 and 11, which recite a memory having a second portion formed below a first portion, establish that the second portion is on the bottom relative to the first portion. Thus, the claim language itself establishes the vertical locations of the memory portions relative to each other (e.g., a second memory portion that is above the first portion is on top, relative to the first portion). It follows that claim terms referring to the top and bottom of word lines within the memory portions also refer to relative vertical locations of the word lines within the memory portions. Thus, we understand the plain and ordinary meaning of claim” slip op. at 13

“We disagree and find that Dong’s Figure 5a does not depict wordlines in a physical vertical orientation, but rather depicts voltage diagrams. We agree with Patent Owner’s argument, supported by persuasive testimony by Dr. Khatri, that a POSITA would have understood that Dong’s voltage charts (e.g., Fig. 5a) simply represent which voltages are applied to which word lines and do not depict the physical orientation of the wordlines. See, e.g., Ex. 2028 ¶ 171 (citing Ex. 1005 ¶ 20; Ex. 1009 ¶¶ 52–54).

“defined stoichiometry” (Ex. 2037, 527) but the word may also be a “generic term for phases . . . which may have a narrow or extended compositional stability range” (id.). The first glossary meaning is consistent with Patent Owner’s position. The second, broader, glossary meaning is consistent with Petitioner’s position. Some of the extrinsic sources before us support the broad definition, and some support the narrow definition. See PO Sur-Reply 3–4 (arguing that Dr. Miles admitted that various treatises distinguish intermetallic compounds from alloys and solid solutions). Thus, neither Dr. Miles or Dr. Raabe is “wrong scientifically” in how they use the term “intermetallic” in this proceeding. Id. at 2 (noting that Dr. Miles agreed that Dr. Raabe’s construction is not wrong scientifically). As explained below, however, only one of these meanings is appropriate here. To decide which possible meaning applies to the ’227 patent, we focus on the patent claims and specification. Claim 1 indicates that the intermetallic layer has a “mean composition” (emphasis added). Ex. 1001, 15:1–10. This indicates, albeit weakly, that iron composition across the layer may vary rather than having ordered stoichiometry—consistent with Petitioner’s position. The specification also indicates that “intermetallic alloying” is a possibility—again, consistent with Petitioner’s position. Ex. 1001, 2:47–50. Meanwhile, nothing in the ’227 specification explicitly (or implicitly) suggests that “intermetallic layer” must be limited to elements atomically joined with defined stoichiometry in an ordered crystal structure. We also find that Dr. Miles’s testimony regarding the meaning of “intermetallic” is more credible than Dr. Rabbe’s testimony. Dr. Rabbe, in deposition, stated that Figure 2 of the challenged patent “does not show a layer that meets [his] construction of intermetallic.” Ex. 1078, 129:21–24. The ’227 patent, however, states that Figure 2 includes an “Al-rich Intermetallic layer.” Ex. 1001, Fig. 2, 3:60–64 (“FIG 2. Illustrates a coating … which does not correspond to the invention. This succession of layers (interdiffusion layer and intermetallic layer) yields inferior results in resistance spot welding.”). Also, Dr. Raabe previously referred to a layer of Takagi as having “intermetallic phase layering and structure.” Pet. Reply 4 (citing Ex. 1076 ¶ 166; Ex ¶ 1075, 17) (emphasis omitted). Thus, Dr. Raabe’s construction of “intermetallic” for this proceeding does not fully account for the ’227 patent usage of the word “intermetallic” and does not fully account for Dr. Raabe’s prior usage of the word “intermetallic.” Patent Owner argues that Petitioner’s construction “erases the meaningful distinction” between the claimed layers. PO Resp. 11. Patent Owner further argues that Petitioner’s construction renders the word “intermetallic” superfluous because allowing the intermetallic layer to be “merely a multi-element alloy erases the meaningful distinction among these layers.” Id. We disagree. The word intermetallic serves to require that the layer be composed of two or more metals or a metal and a metalloid. The word intermetallic also serves as a label to differentiate each of the four claimed layers. For example, in claim 1, the word “intermetallic” is used much like the words “interdiffusion” and “intermediate” to give each of the four layers (each having differently mean compositions) different labels.” slip op. at 16

“have had reason to combine teachings of Takagi and Cornette with a reasonable expectation of success.

In particular, Petitioner argues that Takagi discloses a pre-coating thickness of 10–20 µm but does not explicitly disclose a post hot-stamping coating thickness corresponding to the pre-coating thickness. Pet. 11. Cornette teaches that the hot-stamping thickness causes coating expansion from 25 µm to about 40 µm, an increase of 60%. Id. (citations omitted). Petitioner and Dr. Miles reason that, when hot stamping Takagi’s product, the thickness would be 32 µm. Id. (citing Ex. 1003 ¶ 32); see also Pet. Reply 20–21. Thus, Patent Owner argues that Cornette evidences Takagi’s finally coating thickness without requiring modification of Takagi. Petitioner further argues that Takagi and Cornette teach that post hot- stamping thickness could be varied and optimized as a result effective variable. Id. at 12–13; see also Pet. Reply 17–18. Cornette teaches, for example, that “[t]he average [pre-coating] layer thickness showing the best compromise between corrosion protection and weldability is 25 µm” and links this pre-coating thickness to a final thickness of “about 40 µm at the steel surface.” Ex. 1014, 9. Petitioner also argues that it would have been obvious to fill in other details of Takagi including, for example, selecting USIBOR 1500 steel, based on the teachings of Cornette. Pet. 14. Patent Owner argues that there is no reason to combine Takagi with the teachings of Cornette. PO Resp. 26. Patent Owner makes seven related arguments. Patent Owner first argues that the Petitioner’s position is speculative and lacks basis. Id. at 26–27. We disagree. Cornette evidences a final coating thickness for Takagi, and the references also suggest that final coating thickness is result effective. Second, Patent Owner argues that there would have been no incentive to seek a motivation to seek a thicker coating post-hot stamping. Id. at 28– 35. This argument does not undermine Petitioner’s position that Takagi, by itself, would have reached a thicker coating after stamping as evidenced by Cornette. Pet. 11–12. Petitioner takes the position, with evidence, that practice of Takagi alone would reach the recited thickness. No motivation to modify Takagi is required under this position.” slip op. at 25

Prelim Resp. 21. While it may be relevant, the testimony is not persuasive in light of the Specification. We find the uncontested fact that several of the B moieties alone—without the A moiety or L linker—specifically identified in the ’233 patent fall outside of Patent Owner’s proposed definition persuasive, as we normally do not interpret claim terms in a way that excludes examples disclosed in the specification. See, e.g., Verizon Servs. Corp. v. Vonage Holdings Corp., 503 F.3d 1295, 1305 (Fed. Cir. 2007) (rejecting proposed claim interpretation that would exclude disclosed examples in the specification). The cases cited by Patent Owner supporting that a claim term may be construed to exclude embodiments where the prosecution history supports such construction are factually distinguishable from the instant case as they regard instances of specific prosecution history disclaimer, clear prosecution disavowal, or relate to a specific definition of the terms in the Specification for the term being construed. Here, “low molecular weight” is not defined in the Specification, but, as Petitioner argues (see Pet. 21–25) is characterized as “demonstrat[ing] faster pharmacokinetics and a higher specific signal within clinically convenient times after administration” and that it “can be synthesized in radiolabeled form more easily.” Ex.1001, 13:33–50, 14:56– 16:14, 17:9–20.

“claim 1 would have been obvious over the combined teachings of Hongtao and Yu by a preponderance of the evidence. 35 U.S.C. § 316(e) (2018); see also Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). After considering the parties’ arguments and evidence of record, and weighing the testimony of Dr. Liu and Dr. Przybylski, we are not persuaded that Petitioner meets its burden of establishing, by a preponderance of the evidence, that Hongtao teaches or suggests applying a second bias voltage that is smaller than the first bias voltage in the verify stage as recited in limitation [1.d]. Hongtao is silent with respect to the magnitudes of the pre-conduction and conduction voltages. Hongtao teaches that “a pre-conduction voltage is applied to both the unselected word line and the selected word line to turn on the channels of the selected string and the unselected string.” Ex. 1005 ¶ 23. Hongtao then teaches that, in the reading phase, “[t]he gates of the unselected memory cells on the selected string are applied with a conduction voltage through the unselected word lines.” Id. ¶ 25. Hongtao, however, describes the magnitudes of the pre-conduction and conduction relative to each other. See id. ¶¶ 21–26. Petitioner and Dr. Liu point to Hongtao’s statement that “the greater the conduction voltage, the greater the read disturbance” to support its contention that the conduction voltage is smaller than the pre-conduction voltage, but that statement refers to the relationship between conduction voltage and the read interference it causes and does not compare the conduction voltage to the pre-conduction voltage. See Pet. 40 (citing Ex. 1005 ¶ 26); Ex. 1003 ¶ 120 (citing Ex. 1005 ¶ 26). We also find credible Dr. Przybylski’s testimony that Hongtao lacks the details needed to determine how the gate voltages develop over time, in particular the length of the pre-conduction period. See Ex. 2003 ¶ 96. Dr. Przybylski’s testimony is consistent with the ’957 patent’s teaching that when the pre-pulse time is long enough that the bias voltages are fully developed before the TSG transistor is switched off at the unselected memory cell string, hot carrier injection “may not be generated from the selected memory cell to the upper adjacent memory cell of the selected memory cell in the selected memory cell.” Ex. 1001, 11:60–12:1. In contrast, when the pre-pulse time is insufficient for the bias voltages to fully develop, hot carrier injection may be generated. Id. at 12:1–9. And we are not persuaded that Petitioner and Dr. Liu sufficiently rebut Dr. Przybylski’s persuasive testimony that casts doubt on Petitioner’s contention that Hongtao teaches a second bias voltage that is smaller than a first bias voltage as recited in limitation [1.d]. For example, Dr. Liu’s testimony that Hongtao teaches applying voltages on gate terminals does not adequately address Patent Owner’s argument and Dr. Przybylski’s testimony that Hongtao depicts target values for the word line voltages instead of the See Ex. 1027 ¶¶ 16–40. Neither Petitioner nor Dr. Liu adequately establish that Hongtao’s applied voltages are sufficiently developed such that the preconduction voltage actually is bigger than the conduction voltage. Petitioner’s argument that Hongtao teaches or discloses a second bias voltage that is smaller than the first bias voltage hinges on a POSITA’s interpretation of Hongtao’s Figure 2. In light of Hongtao’s dearth of details regarding the absolute or relative magnitudes of the pre-conduction and conduction voltages, and Dr. Przybylski’s unrebutted testimony that Hongtao does not provide sufficient information to ascertain the actual bias voltages that will be applied on the gate terminals of the memory cells over time, we are not persuaded that Petitioner carries its burden of establishing that Hongtao discloses limitation [1.d]. For these reasons, we determine that Petitioner does not establish by a preponderance of the evidence, that independent claim 1, and claims 2–6 that depend, directly or indirectly, therefrom, would have been obvious over the combined teachings of Hongtao and Yu.” slip op. at 15

“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
