  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

    “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

See, e.g., Ex. 2028 ¶ 171 (citing Ex. 1005 ¶ 20; Ex. 1009 ¶¶ 52–54).

    “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

    “In this case, Mr. McAlexander meets both Petitioner’s and Patent Owner’s proposed level of skill in the art. As a result, we are persuaded Mr. McAlexander has the requisite skill and relevant expertise to offer testimony in this matter. For example, Mr. McAlexander has a Bachelor’s Degree in Electrical Engineering and far more than 2 years of experience in the electrical engineering field. Ex. 1027, 3–6, 7. In addition, Mr. McAlexander has provided expert consulting services in a wide range of technology areas involving the process and design of electro-mechanical consumer products. Ex. 1003 ¶ 5. Through one of Mr. McAlexander’s business ventures, his laboratory has “performed detailed airflow analyses, designing and constructing specialized apparatuses to emulate human breath, allowing for precise activation testing of ENDS devices.” Ex. 1043 ¶ 16.

    “Petitioner’s arguments are not persuasive. Mr. Cornelison’s testimony that a POSITA would understand that the tape shown in Figure 13C “has three layers aligned along the side edges” is not credible. See, e.g., Ex. 1006 ¶ 138. Mr. Cornelison’s testimony that Figure 13C is only “intended to identify and illustrate the three different layers of the multi-layer tape,” not to show the relative positions of the layers relative to each other (id. ¶ 137), is belied by his own testimony, in which he states that Figure 13C shows “metallic layer 133 extends to the front edges of dielectric layers 135 and 137 (id. ¶ 136). Additionally, neither Petitioner nor Mr. Cornelison provide persuasive evidence to support the contention that it would take “much more time and be more complex to make all three layers” in Figure 13C offset from each other or that it would be more costly to make than using the customary slitting processes. See Ex. 1006 ¶ 138. Although Mr. Cornelison provides evidence as to how the slitting process can be used to manufacture barrier tape, he does not provide any evidence to support his contention that the proposed slitting processes is in fact less expensive or complex than other methods. See Ex. 1006 ¶ 138. Indeed, Mr. Cornelison does not address the particular methods disclosed in Glew to manufacture the disclosed multi-layer tapes nor persuasively explain why these disclosed methods would be more costly or complex as compared to the “slitting” process. Ex. 1008 ¶¶ 199–201 (stating the multi-layer tapes can be manufactured in a “variety of ways” including bonding the various layers using adhesive or other bonding agents,” mechanically affixing or bonding the layers, needlepunching, thermal bonding, ultrasonic welding, or calendar bonding). We determine that this portion of Mr. Cornelison’s testimony is conclusory and unsupported and is entitled to little weight. Accordingly, Petitioner has not sufficiently shown that Glew discloses conductive material that extends to the lateral edges of the dielectric material as required by claims 1 and 18. As such, Petitioner has not shown a by a preponderance of the evidence that Glew anticipates independent claims 1 or 18 or the challenged claims that depend therefrom.” slip op. at 42

    “Thus, although the Specification does not use the term “lateral edge,” the Specification and figures of the ’030 patent make clear, that in the embodiments having a conductive layer that extends to the edges of the dielectric layers of the tape, the referred to “edge” is the edge of the “long side” of the tape that extends in the longitudinal direction. See, e.g., Ex. 1001, 7:49–51 (stating in some embodiments conductive layer 302 may not extend to the edge of tape 110), 8:1–25 (stating, inter alia, pairs 102 could electrically couple to the corresponding edge 306 resulting in increased ANEXT), 8:41–46, 10:30–36 (stating that the tape edge lies over a pair of conducts and the pair generates more ANEXT). Our construction of term “lateral edge” is supported by Roberts, which also refers to the edges of the long side of the tape extending in the longitudinal direction as the “lateral edges.” See, e.g., Ex. 1009, 2:20–24 (“a shield made from a plurality of tapes helically disposed, the lateral edges of which overlap adjacently lying tapes”), 2:42–46 (“a shield composed of a plurality of …, the lateral edges of which overlap adjacently disposed tapes”), 4:27–33 (“the plastic-coated metal foil shield (15) [FIG. 2] has lateral edges that overlap,” “the lateral edges of the shield overlapping one another”), 4:34–40 (“The lateral edges of the helically disposed tapes [of FIG. 3] overlap adjacently lying tapes.”), 5:65-75 (“the shield (15) [of FIG. 10] is made up of a plurality of tapes, the lateral edges of which overlap adjacently disposed like tapes”), Figs. 2, 3, 10. We credit Dr. Eldering’s testimony that these disclosures of Roberts shows that a POSITA would understand that a tape’s “lateral edges” are the edges running along the sides of the tape parallel to the longitudinal direction.

See, e.g., Ex. 2007 at 111:3–25. The same is true of Petitioner’s Reply, which reiterates Mr. Andrews’s deposition testimony, but still fails to provide any reason as to why Coffee’s charts or Mr. Andrews’ testimony necessarily means that Coffee copies a portion of the header from the received message to the response message. See Continental Can Co. U.S.A., Inc. v. Monsanto Co., 948 F.2d 1264, 1269 (Fed. Cir. 1991) (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”). And, despite Petitioner’s identification of a “Header” listed in Tables 58 and 63, Coffee does not expressly describe the header or part of the header as being copied from the received message to the response message. The Petition and Mr. Andrews also state that “if Coffee did not employ such copying, the response message would not automatically include information extracted from the received message.” Pet. 38 (citing Ex. 1003 ¶ 118). But, Coffee does not expressly describe the header as being “extracted from the received message” or describe automatically including the header in a response message to make the leap argued by Petitioner and Mr. Andrews. Accordingly, on the full record before us, we find that Petitioner has not established that Coffee explicitly or inherently discloses copying the header or header information and we do not credit Mr. Andrews’ testimony, discussed above, because he fails to provide the underlying factual basis for the opinions offered.” slip op. at 43

    “proceeding and on the full record before us, we do not find that Coffee’s silence is sufficient to support Petitioner’s argument. See Campbell Soup Co. v. Gamon Plus, Inc., 787 Fed. Appx. 731, 739 (Fed. Cir. 2019) (“We do not find any error in the Board changing its understanding of the teachings of [a prior art reference] from the institution decision to the final written decision. ‘The Board is not bound by any findings made in its Institution Decision. At that point, the Board is considering the matter preliminarily without the benefit of a full record. The Board is free to change its view of the merits after further development of the record, and should do so if convinced that its inclinations were wrong.’” (quoting Trivascular, Inc. v. Samuels, 812 F.3d 1056, 1068 (Fed. Cir. 2016))). Coffee does not explain the process by which the IOD of the received message is included in the response message; rather, Coffee just states that the response message “contains the IOD of the message being answered.” See, e.g., Ex. 1005, 56:63–67 (see full text quoted above). In particular, although Coffee attributes certain actions to the operator, the lack of attribution to the operator does not necessitate that the only viable possibility remaining is that Coffee copies the IOD from the received message to the response message. Even if it may be said that Coffee probably (or possibly) copies the IOD, that probability is not sufficient to find that Coffee necessarily copies the IOD. See Continental Can, 948 F.2d at 1269 (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”).7 Additionally, on the full record before us, we determine that Mr. Andrews’s testimony, as with his testimony as to copying of the header and selected response, fails to provide any factual or underlying support for his opinions expressed therein. See Ex. 1003 ¶¶ 100–102. In particular, the leap occurs in paragraph 102, where Mr. Andrews takes the fact that some information (at least the IOD) from the received formatted message is included with the response message to opine that this means the information is “copied over.” Id. ¶ 102. But, again, Coffee is silent. And because Mr. Andrews did not provide any underlying factual basis for his opinion, we do not credit his testimony as to copying the IOD. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 48

    “generally, including the alleged benefits of such and reasons why one of ordinary skill in the art would have been prompted to include field-mapping information in Coffee’s MDT. See id. at 62–70. None of Petitioner’s discussion, however, explains how the combination of Coffee and Heijden remedies the deficiencies that we identified regarding Petitioner’s challenge based on Coffee. In particular, Petitioner does not assert or explain how the teachings of Heijden would be applied to Coffee such that Coffee would then copy or fill in the specific information from Coffee’s received message to Coffee’s response message, particularly as pertains to the header, Response, and IOD fields (which Petitioner relied on in the first ground), or any other information field from Coffee. The same is true of Mr. Andrews’s testimony. See Ex. 1003 ¶¶ 214–231. Additionally, it appears that Petitioner’s analysis of the combination of Heijden and Coffee maintains the position that Coffee copies information fields. See Pet. 70 (“Given that Coffee’s system already implements field mapping to copy information fields . . . .”). And, Mr. Andrews’s testimony similarly maintains that Coffee copies information fields. See Ex. 1003 ¶ 229 (“Coffee also discloses (at least inherently) field mapping by describing that data is copied from fields in request messages into corresponding fields in response message.”). But, as we explain in detail in the context of Petitioner’s challenge based on Coffee, Petitioner has not shown sufficiently that Coffee copies or fills in information from a received message to a response message. Thus, we do not find and Petitioner does not allege that Ground “1B” fills the gaps identified in Petitioner’s Ground “1A.”10 Accordingly, we determine that Petitioner has not established, by a preponderance of the evidence, that the combination of Coffee and Heijden would have rendered the subject matter of claims 1–4, 7–9, and 12 unpatentable.” slip op. at 60

    “frequency response and that a POSITA would have understood that Hirose’s filter is “tuned to reject a narrow band of frequency,” which operates “like a narrow band-rejection filter (aka notch filter).” Pet. 28–29. Petitioner’s argument that Hirose discloses or suggests a narrow band-rejection filter is contained in this short portion of the Petition and relies on an inference that a V-shaped curve necessarily signifies a narrow band-rejection filter. Any such inference that a V-shaped curve is sufficient to characterize a filter as a narrow band-rejection filter, however, is belied by Dr. Subramanian’s own testimony. Indeed, Dr. Subramanian explains that the shape of a curve alone, including the shape of the curves of Figures 2–9(G) and (H) of Gibilisco, is not sufficient on its own to determine whether a filter corresponding to that curve is a narrow band-rejection filter or a broad bandrejection filter. See, e.g., Ex. 2030, 69:13–18 (stating, just looking Figure 2– 9(H), he could not tell if the figure corresponds to a narrow band-rejection filter because “I don’t have enough information”). Dr. Subramanian further testified that additional information beyond the mere shape of the curve is required to determine if the curve represents a narrow band-rejection filter; for example, Dr. Subramanian states that it was Gibilisco’s characterization of Figure 2–9(G) as having a sharp band rejection response that led him to conclude it was a narrow band-rejection filter. See Ex. 2030, 68:20–69:4 (Dr. Subramanian testifying that he would not “characterize the figure depicted in G as a narrow band” based just on the figures, but “on all the information that’s given,” which includes “this reference specifically [stating] at G, ‘sharp band rejection response’”); see also id. at 60:24–61:23, 62:7–63:11.
