      “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13. And, for the reasons discussed herein, the charge cut-off voltage may be, but is not necessarily, the same as the applied voltage during charging. PO Resp. 20.” slip op. at 15

      “constructions. First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

      “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed. Cir. 2011) (noting that “a patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority . . . Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120”). Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28. In view of the foregoing, we are not persuaded that Patent Owner has demonstrated that the inventors of the priority applications were in possession of a magnesium cast composite that included less than 50 wt. % magnesium, or greater than 50 wt. % additives. As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

      “specification support its construction of “formed or mounted to” as encompassing indirect attachment to the substrate. Neither the plain claim language nor the specification requires the phosphor coating to be directly attached to the substrate. Limitation 1(c) recites, wherein the LED chips comprise a phosphor coating to produce a change in a color or a quality of light emitted from the LED chips, wherein the LED chips, the power connection leads, and the phosphor coating are formed or mounted to a flexible substrate that is sufficiently flexible to be formed into a cylindrical shape[.] Ex. 1001, 22:7–12 (emphasis added). The claim is inartfully written, as it requires the LEDs to comprise a phosphor coating but then separately recites that the LED chips and the phosphor coating are formed or mounted to the substrate. But Petitioner correctly explains that the plain meaning requires that “the LED chips comprise a phosphor coating” and that “the [same] phosphor coating” (included in the LED chips) is “formed or mounted to a flexible substrate.” Reply 2. In other words, the use of the term “the” before “phosphor coating” indicates reliance on the antecedent basis of “LED chips comprise a phosphor coating,” and thus the same coating of the LED chips is formed or mounted to the substrate. Logically, by including a phosphor coating with the LED chips, which are formed or mounted to the substrate, the coating of these chips is also indirectly formed or mounted to the substrate. Conversely, it would be illogical to conclude that the claim recites two phosphor coatings, one attached to the LED chips and another attached directly to the substrate, because the structure of the claim refers to a single phosphor coating of the LED chips. Even Patent Owner concedes that the claim encompasses the phosphor coating indirectly being mounted or attached to the substrate (in addition to being directly attached). PO Resp. 11 (“The ordinary English reading of the claim language does not encompass the phosphor coating only being indirectly attached to the substrate, instead, the language indicates that the coating is directly applied to the substrate.” (emphasis changed)), 13 (“the phosphor coating . . . is not merely attached to the substrate indirectly”).” slip op. at 10

      “After considering Patent Owner’s arguments, which we address below, we agree with Petitioner that the combination of Wojnarowski and Martin discloses this limitation and that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner. Briefly, we summarize our findings, and then we address the parties’ arguments in more detail. First, we agree with Petitioner, and Patent Owner does not dispute, that Wojnarowski’s AC input voltage would have been converted to DC voltage in light of the bridge rectifier and capacitor disclosed by Wojnarowski.

Second, we further agree with Petitioner, and Patent Owner does not dispute, that excessive current due to too few LEDs would have harmed Wojnarowski’s LEDs, and too small a current due to too many LEDs would be insufficient to power Wojnarowski’s LEDs. Pet. 26; Ex. 1002 ¶ 134; PO Resp. 48 (discussing, but not disputing, these assertions).13 Third, we agree that a POSITA would have recognized in view of Martin’s teachings and the knowledge of a skilled artisan that when configuring Wojnarowski’s device, the total forward voltage drop of the series-connected LEDs should approximately match the DC voltage output 13 Petitioner explains the relationship between voltage and current for the LEDs as follows: “the total voltage drop of the circuit would dictate the current drawn by the LED circuitry, which would have been known to be inversely proportional to the voltage.” Pet. 26 (citing Ex. 1002 ¶ 134). of Wojnarowski’s circuit.

For example, Martin teaches that “[t]he number of LEDs in the monolithic array may be selected to achieve a particular voltage drop across each device.” Ex. 1006 ¶ 22. Martin further explains, “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series,” and “[t]he number of LEDs is chosen such that the maximum voltage across each individual LED during the peak in the alternating current cycle is low enough so as not to damage the LEDs.” Id. The forward voltage drop across Martin’s 38 LEDs is about 171 V, which matches Martin’s AC input voltage peak of about 169.71 V. See id. (“At 120 RMS volts, the peak voltage will be about 180V [correction: 169.71 V],” and if the LEDs “can tolerate a maximum forward voltage of 4.5V, at least 38 LEDs connected in series are required.” (38 LEDs x 4.5 V = 171 V)); PO Resp. 41–42 (“While Martin references ‘about 180V,’ both parties agree that the correct value of the peak voltage Vp is 169.71 V.” (citing Ex. 1002 ¶ 127)).

This statute provides that “[a] petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” § 311(b) (emphasis added). Patent Owner contends that Martin is not available as prior art under 35 U.S.C. § 311(b) because it is not a patent or printed publication and is only prior art under 35 U.S.C. § 102(e). PO Resp. 22. Patent Owner argues that documents are “printed publications” as of the date they become available to the public, and Martin became public on its publication date of October 21, 2004, after the February 25, 2004 priority date of the ’979 patent. Id. at 23. Patent Owner raises a similar argument for the Soules-II reference in Ground 6. Id. at 25– 26. Petitioner responds that the AIA framework permits the use of § 102(e) prior art in IPR proceedings, unlike formerly available covered business method review (CBM) proceedings, which restricted challenges to § 102(a) prior art. Reply 29. We agree. The statute governing the formerlyavailable CBM proceeding explicitly limits challenges based on “prior art that is described by section 102(a).” AIA § 18(a)(1)(C). In contrast, § 311(b) more broadly permits challenges “on the basis of prior art consisting of patents or printed publications.” The broader language in § 311(b) implies that unlike CBMs, IPRs are not limited to challenges solely under § 102(a) prior art. The parties cite to no Federal Circuit decisions that squarely address this issue. However, the Federal Circuit has applied § 102(e) patent application publication prior art in appeals from IPR proceedings. See, e.g., Purdue Pharma L.P. v. Iancu, 767 Fed. App’x 918, 920–21, 926 (Fed. Cir. 2019) (nonprecedential) (determining that a § 102(e) patent application publication was available as prior art in an IPR). The Board has also long permitted challenges based on patent application publications under § 102(e). See, e.g., Idle Free Sys., Inc. v. Bergstrom, Inc., IPR2012-00027, Paper 14 at 27 (PTAB Jan. 31, 2013) (instituting trial over § 102(e) ground based on a patent application publication). We therefore find Patent Owner’s § 311(b) argument unpersuasive.” slip op. at 34

We turn to Linden’s disclosure relied on by Petitioner. Linden discloses that “[t]he similar items table 60 could also reflect non-collaborative type item similarities including content-based similarities derived by comparing item contents or descriptions.” Ex. 1003, 9:12–15 (emphasis added).

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

      “Generally, a preamble is not limiting.” Summit 6, LLC v. Samsung Elecs. Co., 802 F.3d 1283, 1292 (Fed. Cir. 2015). Whether a preamble is limiting is “determined on the facts of each case in light of the overall form of the claim, and the invention as described in the specification and illuminated in the prosecution history.” Applied Materials, Inc. v. Advanced Semiconductor Materials Am., Inc., 98 F.3d 1563, 1572–73 (Fed. Cir. 1996). A preamble limits the claimed invention if it recites essential structure or steps, or if it is “necessary to give life, meaning, and vitality” to the claim. Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1305 (Fed. Cir. 1999). A preamble is not limiting, for example, if the patentee “defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.” Catalina Mktg. Int'l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002). And, a preamble is generally not limiting unless there is “clear reliance on the preamble during prosecution to distinguish the claimed invention from the prior art.” Id. A preamble can be limiting if it recites “additional structure or steps underscored as important by the specification,” is “essential to understand limitations or terms in the claim body,” or provides necessary structure absent from the claim body. Id. at 808–09. We agree with Petitioner that the preamble is not a limitation. The term “swaddling suit” is merely a descriptive name for the apparatus that is covered by the claims. IMS Tech, Inc. v. Haas Automation, Inc., 206 F.3d 1422, 1434 (Fed. Cir. 2000) (Terms in the preamble are not limiting if they “merely give[] a descriptive name to the set of limitations in the body of the claim that completely set forth the invention.”). It is well-established that “[a]pparatus claims cover what a device is, not what a device does.” Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1468 (Fed. Cir 1990). For example, in Cochlear Bone Anchored Solutions AB v. Oticon Med. AB, the Federal Circuit held that a statement of intended purpose in the preamble—“for rehabilitation of unilateral hearing loss”—was not limiting, because the claimed apparatus was fully structurally claimed in the body of the claim, and its structure would allow it to function identically whether or not used for its stated intended purpose. See 958 F.3d 1348, 1355 (Fed. Cir. 2020). We find that this is the case here. The bodies of claims 1 and 2 recite structurally complete inventions, which would function identically whether or not they are used for its stated intended purpose. Indeed, if the term “swaddling suit” were replaced by the word “garment,” it would not change the nature of the claim. This interpretation is consistent with the Specification that The invention has been developed primarily for use as a means for swaddling infants for safe sleeping. However, it will be appreciated that the invention is not restricted to this particular use.

      “meaning. But we further agree with Patent Owner that the plain and ordinary meaning for that term is simply “to hold or to keep.” See Ex. 2022. Petitioner’s argument that the Specification uses “retain” to mean that the wing portions are closed, as opposed to having open ends like sleeves reads retain out of context. The portion of the Specification identified by Petitioner states The ends of the wing portions 140 may be open, allowing the hands to extend through the opening end as shown in FIG. 5E. Alternatively, the ends of the wing portions 140 may be closed so that the hands are retained within the wing portions 140 as shown in FIGs. 5C and D. Ex. 1001, 10:3–7 (emphasis added). We do not read this passage as creating a special meaning for “retained,” as Petitioner suggests. Reply 7–8. Petitioner focuses on the portion of this statement that “the ends of the wing portions . . . may be closed so that the hands are retained. . .” to argue that the Specification uses the term “retained” to mean “closed.” However, this argument ignores the end of the sentence that “the ends of the wing portions . . . may be closed so that the hands are retained within the wing portions.” When considered in its full context, we agree with Patent Owner that this passage is consistent with Patent Owner’s construction. See Sur-Reply 11. Indeed, the passage simply uses “retained” in its ordinary sense—i.e., “the ends of the wing portions 140 are closed so that the hands are [held or kept] within the wing portions.” Accordingly, we determine that “retain” has its plain and ordinary meaning, i.e., “to hold or retain.”” slip op. at 14

      “7. Our Analysis of Claim 1 As we analyze the evidence, Mattaboni’s Figure 4 does not relate to any characteristic of its memories that limits the frequency range of recorded seismic data. Rather, Mattaboni’s Figure 4 is “the product of the manufacturer’s specified response curve for the geophone and the measured transfer function of the preamp and filter blocks of Figure 3.” Ex. 1006, Fig. 4 (caption). Mattaboni discloses that its memories are capable of recording data at 120 times per second, or 60 Hertz, and thus above the 50 Hertz that Patent Owner contends is necessary to record “seismic data.” Regarding Patent Owner’s statements (1) and (2) above, Patent Owner’s declarant does not disclose the underlying facts or data on which these opinions are based, and they are thus entitled to little or no weight. 37 C.F.R. § 42.65(a). Regarding Patent Owner’s statement (3), Mattaboni states that the displacement response peak of its instrument is between 25 and 35 Hertz, which is the most important range for microearthquakes. Ex. 1006, 5. Mattaboni, however, also states the effective frequency band of the disclosed instrument is “from about 2 Hz to somewhat over 50 Hz (Figure 4).” Id. at 5. Thus, Mattaboni’s instrument records signals “somewhat over 50 Hz” which is “at least above 50 Hz” and in the frequency range which Patent Owner’s declarant contends is needed to record “seismic data.” Ex. 2051 ¶ 35; Ex. 1104, 301:5–302:1 (testifying that 8–50 Hz range is minimum for “seismic data” under Patent Owner’s construction).” slip op. at 28

Claim terms must be construed, however, in light of the specification. See In re Translogic Tech., Inc., 504 F.3d at 1257. In the Specification, the 761 Patent describes “seismic data” as resulting from an acoustic signal from a seismic energy source that propagates into the earth and is partially reflected at subsurface lithologic or fluid boundaries and is detected and recorded as seismic energy data by seismic receivers. Ex. 1030, 1:12–23. Petitioner argues that this passage of the 761 Patent does not mention “seismic data.” We note, however, that this passage does mention “seismic energy data” which is shortened to “seismic data” when mentioned later in the 761 Patent. See, e.g., Ex. 1030, 2:48–51, 3:17–19, 3:26–30, 3:35–40, 3:61–63, 9:41–63.

Reply. 10 (citing Exs. 1112– 1114, 1121). Patent Owner argues that its constructions are consistent with, and supported by, other publications from the oil and gas industry. PO Resp. 33 (citing Ex. 2003; Ex. 2004, 213–232). Collectively, these publications establish that the term “seismic data” is used differently in different fields, but the best source for determining the meaning of a claim term is the patent’s Specification. See, e.g., In re Abbott Diabetes Care Inc., 696 F.3d 1142, 1149–50 (Fed. Cir. 2012); In re Suitco Surface, Inc., 603 F.3d 1255, 1260–61 (Fed. Cir. 2010); Vitronics Corp. v. Conceptronic Inc., 90 F.3d 1576, 1583 (Fed. Cir. 1996). As the 761 Patent uses the term “seismic data” consistent with the meaning proposed by Patent Owner, and not the more expansive definition proposed by Petitioner, we adopt Patent Owner’s proposed construction as the correct one to use for our analysis in this decision. The plain meanings of claim terms are construed not in a vacuum, but in the context of the entire patent disclosure. See In re Translogic Tech., Inc., 504 F.3d at 1257.

For the purposes of the Decision on Institution, we determined that, based on the record at that time, no claim term required express construction (Dec. on Inst. 7), and we see no reason to modify that determination in light of the record developed during trial.

      “considerably greater than Ishikawa’s stylus load of 50–300 μN (Ex. 1015 ¶ 45). The Talke Declaration does not address this discrepancy, and Dr. Talke stated during his deposition that reducing the stylus load would reduce scratching of the magnetic tape surface. Ex. 1030, 108:14–19 (“Q: Would reducing the contact pressure for the stylus instrument reduce the scratching of the magnetic tape surface by the stylus? A: Yes, it would, but you have to remember the other problem is the diameter and size of the stylus.”). Moreover, Petitioner provides evidence that it was not uncommon to use stylus-type profilometers to measure the properties of magnetic tape, even after Bhushan was published in 1996. See Reply 6. In particular, Petitioner points to Saliba,6 which describes using a stylus-type profilometer, under identical conditions to those used in Ishikawa, to measure the surface characteristics (including peak-to-valley roughness) of the backcoating of magnetic tape. Ex. 1027, 7:28–40, 57–60. Petitioner further points to Ohno,7 which also describes using “a stylus type 3D profilometer in accordance with JIS B0601” to measure the surface roughness characteristics of magnetic tape. Ex. 1028 ¶ 36; see also Ex. 1015 ¶ 45 (Ishikawa explaining that surface roughness characteristics were measured “in accordance with JIS-B0601-1994”); Ex. 1027, 7:28–39 (Saliba explaining that surface roughness characteristics where measured “in accordance with JIS-B0601-1994”). Accordingly, we are persuaded that the 6 US Patent No. 6,558,774 B1, issued May 6, 2003 (Ex. 1027). 7 U.S. Patent App. Pub. No. US 2005/0175866 A1, published Aug. 11, 2005 (Ex. 1028). evidence establishes that a stylus-type profilometer is a suitable device for measuring the surface characteristics of magnetic tape.” slip op. at 19

      “We agree with Petitioner that Ishikawa teaches “peak-to-valley roughness less than about 325 nm” as recited in claim 15. Pet. 24–25; Reply 5–8; Ex. 1003 ¶ 216. In particular, Ishikawa teaches a backcoating layer of a magnetic tape that has a peak-to-valley roughness “Rz of 40 to 250 nm, particularly 50 to 200 nm.” Ex. 1015 ¶ 44. Ishikawa provides five example embodiments of its magnetic tape, and reports the measurements of a number of characteristics of the backcoat layer for each example, including peak-to-valley roughness Rz. Id. ¶¶ 120–134, Table 1. Ishikawa discloses that peak-to-valley roughness Rz was measured using a stylus-type profilometer under the following conditions: Stylus: diameter: 1.5 to 2.5 μm; curvature: 60º Contact pressure: 50 to 300 μN Cut-off length: 80 μm Sampling length: 80 μm Assessment length: 400 μm Id. ¶¶ 45, 49. The reported peak-to-valley roughness Rz values for the five examples ranged from 58 to 87 nm, as shown in the annotated portion of Ishikawa Table 1 from the Petition, reproduced below: Pet. 24 (citing Ex. 1015, Table 1). The annotated portion of Ishikawa Table 1 shows the results for the measured characteristics of the backcoat layer of Examples 1–5, with the peak-to-valley roughness Rz values highlighted by a red box. Id. Because Ishikawa teaches that the backcoating layer of its magnetic tape should have a peak-to-valley roughness “Rz of 40 to 250 nm, particularly 50 to 200 nm,” and because Ishikawa presents examples of magnetic tape with backside surfaces having a peak-to-valley roughness of 87 nm or less, Ishikawa discloses “a peak-to-valley roughness less than about 325 nm” as recited in claim 15.” slip op. at 16
