      “Petitioner filed a Petition (Paper 2, “Pet.”) requesting institution of an inter partes review of claims 1–15 of the ’698 patent. Discretionary denial of institution was determined to be not appropriate in this proceeding, and the proceeding was referred to the Board. Paper 10.

      “Following the Institution Decision, both parties submitted proposed claim constructions in the district court stating that the preamble is limiting. 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. Reply 5. At the oral hearing, Petitioner acknowledged that it does not dispute that the entire preamble of claims 1 and 6 is limiting. Tr. 20:25–21:17, 23:15–17. Because the parties agreed in district court that the entire preamble of claims 1 and 6 is limiting, and also agree in this proceeding, we find that the preambles of claims 1 and 6 are limiting for purposes of this Decision. We will discuss the meaning of the preamble further in the sections below applying the prior art to the claims. See §§ III.A..4(a), III.A.7, III.C.1(a), III.C.7, infra.” slip op. at 15

      “Based on the full trial record, we find that Petitioner has failed to meet its burden to show that Bernstein recites a “service auto-configuration” method as recited in the preamble of claim 1. 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. Dec. 32. Instead, the Petition merely explains how Bernstein teaches “a DOCSIS Provisioning of EPON (DPoE) system,” without explaining how it teaches a “service auto-configuration method.” Pet. 24 (citing Ex. 1005 ¶ 59). By failing to offer a construction of “service auto-configuration method” or explain how this limitation is met by the prior art, the Petition fails to show by a preponderance of the evidence that the prior art discloses or suggests this limitation.” slip op. at 34

      “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. Cir. 2000) (“In the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings.”). Holding otherwise would fail to give any effect to the word “direct” as it appears in claims 1, 6, and 10. See Stumbo v. Eastman Outdoors, Inc., 508 F.3d 1358, 1362 (Fed.

Dr. Litvin concedes, for Patent Owner, that “there is no conceivable way the [ITU] did not consider the proposed transition” between the ONU’s two low-power states when drafting G.987.3, although he contends the standards body prohibited such direct transitions as “a conscious and reasoned design choice.” Ex. 2007 ¶ 108; see also id. ¶ 109 (opining that there were only four possible choices for transitions in the ONU, and the ITU “undoubtedly considered all of them, including the direct transition from . . .

Additionally, Dr. Prucnal’s definitions have shifted, and his latest definition purports to be based on Dr. Tentzeris’s characterization of the level of ordinary skill, but changes “experience designing integrated circuits or inductors for semiconductors” to “experience designing integrated circuits and inductors for semiconductors” without sufficient explanation of the reasons for the change. Supp. Prucnal Decl. ¶ 8; Reply Tentzeris Decl. ¶ 56. However, our Decision in this case would not change under Patent Owner’s revised articulation. See Reply Tentzeris Decl. ¶ 57 (stating that his opinion would not change under Patent Owner’s revised definition of the level of ordinary skill).” slip op. at 9

    • 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. Bush Hog, LLC, 703 F.3d 1349, 1357–58 (Fed. Cir. 2012); PO Resp. 7–8.” slip op. at 12

    • 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
