Ex. 2009, 3–4 (Petitioner’s Preliminary Claim Construction Chart); Ex. 2010, 7 (Patent Owner’s Preliminary Claim Construction Chart). Patent Owner states in the Patent Owner Response that “[t]he parties now agree that the entire preambles of both claims 1 and 6 are limiting.” PO Resp. 17. In its Reply, Petitioner states that “whether the Board finds the phrase ‘service auto-configuration’” in the preamble to be limiting is “immaterial” because it “does not affect the analysis of whether the prior art cited in the petition invalidates [the challenged] claims.” Pet.

As discussed above, the parties agree that the preamble of claim 1, including the “service auto-configuration method” language, is limiting. See § II.B, supra. As we explained in the Institution Decision, the Petition does not set forth a construction of “service auto-configuration method” or explain how the prior art discloses a “service auto-configuration method.” Pet. 11, 24; Inst.

    “We agree with Petitioner. The evidence of record, including the ’892 patent and its prosecution history,9 indicates that the ordinary and customary meaning of “transitioning . . . from . . . to” encompasses both direct and indirect transitions. Looking first to the claim language itself, the word “directly” appears in claims 1, 6, and 10, but not claim 14, presumptively suggesting that claim 14 was intended to more broadly capture systems with either direct or indirect transitions. See CAE Screenplates Inc. v. Heinrich Fiedler GmbH, 224 F.3d 1308, 1317 (Fed.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble not limitingDecided for petitioner

    “After considering the full trial record, we agree with Petitioner that the phrase “on a semiconductor die” in the preamble of claim 11 is not limiting. First, we determine that the phrase “on a semiconductor die” in claim 11 does not provide antecedent basis for terms in the body of the claim. The body of claim 11 does not refer to “the semiconductor die” or even mention the “semiconductor die” at all, and neither do any of the claims that depend from claim 11. We disagree with Patent Owner’s argument that the phrase “on a semiconductor die” in the preamble of claim 11 provides antecedent basis for the term “the first inductor” in the body of the claim, because the “first inductor” language in the preamble provides antecedent basis for “the first inductor” language in the claim’s body. The “on a semiconductor die” language in the preamble is presented separately and can be easily parsed from the preamble’s language reciting a “first inductor” without impacting the understandability or grammatical completeness of claim 11. Therefore, the “on a semiconductor die” language in claim 11’s preamble is not necessary to provide antecedent basis for the phrase “the first inductor” in the body of claim 11. This use of language in claim 11 is distinguishable from the Federal Circuit’s opinion in Deere v. Bush Hog, cited by Patent Owner, where the preamble term “rotary cutter deck” provided antecedent basis for the term “said deck” recited in the claim body, because in Deere, the words “rotary cutter” appeared directly before, directly modified, and were not easily parsed from the term “deck.” See Deere & Co. v.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner

    “We agree with Petitioner that claims 1 and 11 do not require that the first and second inductor be laterally spaced, but instead merely require that the second inductor be positioned at a “predetermined distance” from the first inductor. Nothing in the claim language restricts this “predetermined distance” from being in the X, Y, or Z direction, or requires that the inductors be laterally spaced in the same plane. Moreover, the fact that the ’430 patent Specification describes embodiments where the inductors are laterally spaced in the same plane does not limit the claims to those embodiments. As explained previously, our reviewing court “has expressly rejected the contention that if a patent describes only a single embodiment, the claims of the patent must be construed as being limited to that embodiment.” Liebel-Flarsheim, 358 F.3d at 906. “Even when the specification describes only a single embodiment, the claims of the patent will not be read restrictively unless the patentee has demonstrated a clear intention to limit the claim scope using ‘words or expressions of manifest exclusion or restriction.’” Id. We see no such “words or expressions of manifest exclusion or restriction” here. Accordingly, we give the term “predetermined distance” its ordinary meaning, which includes a distance in any direction. The parties do not dispute that Taniguchi’s inductors are spaced apart with an insulation layer in between. Therefore, under the ordinary meaning of the claim language, Taniguchi’s second inductor is “positioned at a predetermined distance from the first inductor.”” slip op. at 26

    “We agree with and adopt the ITC’s construction of “closely spaced,” which is “two terminals in proximity to each other (such that the electromagnetic field at a certain distance from the first inductor (where the second inductor is positioned) is reduced.” Ex. 1020, 12. We find that this construction is supported by the intrinsic record, including the Specification of the ’430 patent, which shows terminals being “closely spaced” compared to the dimensions of the inductor itself, and explains that the purpose of the close spacing is to make the field contributions from the two parts of the inductor identical. See Ex. 1005, Figs. 1–2, 4:28–32. Claims 1 and 11 of the ’430 patent lack specific dimensions for either the inductor or the spacing between the terminals, and indicate that the purpose of the close spacing is to “minimiz[e] magnetic field contributions from the terminals.” Ex. 1001, 10:22–25, 11:7–10. Dr. Prucnal’s ITC declaration, although not intrinsic evidence, further supports our conclusion. Although Patent Owner does not propose a construction for “closely spaced terminals,” it appears to argue that this term must be interpreted based on the dimensions of the semiconductor chip described in the ’430 patent. PO Resp. 43. We do not see any basis in the intrinsic or extrinsic evidence to impart such a narrow reading to the claim language, particularly because the ’430 patent Specification does not define the “closely spaced terminals” in relation to a semiconductor chip, and claim 1 is not limited to inductors on a semiconductor chip.” slip op. at 40

At that juncture, after a user selects the content source and it is highlighted, the content source is then associated with the first content information, “801 – CNXN,” which is displayed on the right panel of Figure 15B. See id. We do not understand the ’040 patent as requiring the display “801 – CNXN” to cause the corresponding highlighting of Live TV 1504A as suggested by Multimedia. The claim language requires the two elements “being associated with”5 one another, but it does not require that one element’s display (first content information) causes the highlighting of the other element (content source). Our view is supported by the only description of highlighting a content source found in the specification of the ’040 patent. In regard to Figure 15B, the specification describes that “global panel 1404 may include one or more sources represented by icons and text, or shortcuts, 1504A-E.” Ex. 1001, 30:27–28. The specification describes how highlighting the source is user directed: Global panel 1404 may additionally indicate a source that is selected or highlight [sic] using indicator 1512; for example, indicator 1512 may comprise a box positioned around Live TV 5 As the Federal Circuit has explained, “the plain meaning of associating relates to a mere commonality.” Apple Inc. v.

Id. at 30:41–49 (emphasis added). Highlighting, as the specification describes, occurs when a user selects a source using indicator 1512 and that source is boxed or differentiated by color or shading. Id. The specification, in relation to Figure 15C, further describes a user moving indicator 1512 to another source such that the “the content or a preview of the content may be displayed in active content area 1408.” Id. at 32:9–17 (“For example, FIG. 15C illustrates an image or video associated with Skyfalls being displayed in content area 1408.”).

See Cont’l Circuits LLC v. Intel Corp., 915 F.3d 788, 799 (Fed.

Here, the portions of the Specification relied on by Petitioner (Ex. 1001, 2:10–20, 4:53–64) disclose a process for manufacturing but do not make clear that the process is an essential part of the claimed invention. We also disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from Pfirsch’s rounded corners, which, presumably, are formed as an incidental result of lithography. On the contrary, the Examiner found (and Patent Owner acknowledged) that Pfirsch has rounded corners. Ex. 1002, 276, 295, 302.

    “is ‘known’ is not sufficient for a motivation to combine.” PO Resp. 47. However, the motivation-to-combine analysis is a flexible one, and the “known-technique” rationale is adequate to show a motivation to combine. For example, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417; see also Intel Corp. v.

Here, as discussed above, the record shows that top view rounding was a known technique to eliminate corners, and that corners were a known problem (e.g., corners tend to reach undesirable higher peak electric field leading to premature breakdown voltage). See, e.g., Ex. 1003 ¶¶ 37, 39, 42– 44, 55–57, 122, 133, 135–141; Ex. 1005, 7:57–8:4; Ex. 1006, 1:18–21, 2:19–39, 5:3–17, Figs. 6A–8B; Ex. 1011, 1:29–41; Ex. 1012; PO Resp. 13, 46 (citing Ex. 1011, 1:34–40); Ex. 2021 ¶ 87.

Cir. 2000) (patent drawings not designated as being drawn to scale cannot be relied upon to define precise proportions of elements if the specification is completely silent on the issue). However, we do not agree that Petitioner failed to show Kobayashi suggests the recited diameter. We disagree with Patent Owner’s assertion that Dr. Liu’s “vague, purported ‘design considerations’” are “unsupported.” PO Resp. 43. Although Kobayashi is silent on the width/diameter of the trench contact in Figure 5A, Kobayashi discloses trenched gates having dimensions below 0.5 μm, which demonstrates that it was known in the art, and required no more than an exercise of ordinary skill in the art, to create trenched features of widths well below 1 μm. Kobayashi also discloses that the width of each trench, and the distance between the adjacent trenches (which includes the trench contact), must be selected to optimum sizes . . . [and] these sizes . . . have some degrees of freedom.” Ex. 1005, 7:42–48. This demonstrates a POSITA would seek to optimize trench contact width or diameter. Dr. Liu’s testimony regarding design considerations suggests the desirability of a reduced diameter trench contact, e.g., to minimize the width of the trench contact for purposes of easier filling, to minimize the total width of the unit cell, and to minimize manufacturing time by reducing etch back time. See Ex. 1003 ¶¶ 111–114. As Patent Owner acknowledges, “there is always a motivation to speed up the fabrication process or shrink feature sizes of semiconductors.” PO Resp. 43 (citing 2021 ¶ 131). However, contrary to Patent Owner’s arguments, these are not generic motivations “untethered” from Kobayashi. Id. Indeed, Kobayashi directly addresses the fabrication process (including new techniques to obtain trench widths under 0.5 μm) and the need to optimize the size of trench gates and the space in between (which includes the trench contact). Ex. 1005, 7:43–54, 7:19–9:53. Patent Owner also argues that Petitioner presents no evidence that modifying Kobayashi to have a diameter smaller than 1 μm is predictable. PO Resp. 44. We disagree. As discussed above, Petitioner points to Kobayashi’s teachings that the sizes are to be optimized and that the trench gate width is smaller than 0.5 μm, which suggests making other trench features of that width was within ordinary skill. Ex. 1003 ¶ 112. Furthermore, Kobayashi’s silence as to the dimensions of the trench contact suggests that the trench contact diameter dimension is likely in the ballpark of the other explicitly disclosed trenched feature dimensions and is a matter of routine optimization. In addition, Patent Owner advances no persuasive evidence that the claimed diameter produces unexpected results or is otherwise critical. Patent Owner also argues that reducing trench contact diameter has downsides (i.e., reduced ease of filling for metal plugs and reduced current carrying capacity) not addressed by Petitioner; however, Petitioner is not required to address those tradeoffs in its Petition, and we do not see how those tradeoffs would prevent the proposed combination. PO Resp. 44; see Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.”); Winner Int'l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.”). Here, Dr. Liu listed numerous benefits of having a reduced diameter, which weigh against the potential downsides raised by Patent Owner. Ex. 1003 ¶¶ 111–114. Moreover, we do not see how the downsides/tradeoffs prevent modifying Kobayashi in the manner suggested when the same tradeoffs appear to be applicable to the ’409 patent.
