We need not resolve the precise meaning of “charge cut-off voltage” because there is no dispute that Yamaki discloses this limitation under either party’s interpretation of the claim term.

      “Patent Owner’s arguments do not persuasively undermine Petitioner’s position. Sakamoto expressly discloses setting the ratio of negative to positive electrode active material in the range of 1.05 to 1.30. Ex. 1005 ¶ 8. Sakamoto also explains why this range is preferable, i.e., if the ratio is roughly equal “the charge-discharge cycle performance is insufficient due to significant deterioration from charging and discharging,” and if the ratio is 10 Citations to the prosecution history of Yamaki are to the page numbers added to the lower right corner of the document. too high “too much of the compound does not participate in charging and discharging.” Id. ¶¶ 6, 8. These disclosures are sufficient to explain why one of ordinary skill in the art would have found it obvious to select the ratios disclosed in Sakamoto in Yamaki. Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Rather, Sakamoto warns against setting the reversible capacities of the positive and negative electrode substantially equal as this may result in excess lithium plating on the surface of the electrode. Ex. 1005 ¶¶ 6, 8. We agree with Petitioner that this disclosure would lead one of ordinary skill in the art to design a battery with a higher capacity in the negative electrode active material than the positive electrode active material.

      “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.

      “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.

      “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.

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

      “Dr. Ducharme’s testimony that “the spacing of the chips in Zhang would not likely be so close as to create overheating issues” (Ex. 2002 ¶ 111) is unsupported by any disclosure of the actual spacing of Zhang’s chips. Consequently, his testimony that there would be no overheating concerns in Zhang due to the spacing of the chips is entitled to little, if any, weight. Dr. Ducharme further testifies that the components of Zhang’s driver “could easily increase the temperature of the LED 19 chips on the circuit board, which can cause LEDs to generate less illumination, burn out and otherwise adversely affect their performance.” Ex. 2002 ¶ 126. Dr. Ducharme further testifies that “[i]t is well-known that excessive operational temperatures can reduce the illumination provided by the LEDs, can decrease the operational lifetime of the LEDs, and if the temperature is sufficiently high, it can cause LED junction failure and a burnt-out LED.” Id. We agree with this testimony, which as discussed below, is consistent with Salam. Dr. Ducharme’s testimony concerning overheating issues caused by the driver components contradicts Patent Owner’s ’s contention that there would not be “an overheating issue with Zhang’s LED exit sign circuit in Figure 2.1.” PO Resp. 30. Regardless of whether Zhang’s LEDs in Figure 2.1 have a heat problem or not, Salam teaches the advantages of using a heat sink. Salam teaches that a heat sink will result in a higher efficiency of the LEDs and improved life. Ex. 1006, 16:38–43. The Federal Circuit, in DyStar Textilfarben GmBH & Co v. C.H.

In its analysis, Patent Owner parses “heat sinking reflective material” out of context by omitting the italicized language “the package is” preceding “heat sinking reflective material.” PO Resp. 29. The deposition testimony of Dr. Lebby and Dr. Ducharme’s declaration testimony cited by Patent Owner are also out of context.

Because heat sink and reflective material are listed separately in the Specification, this disclosure suggests that, at least in certain embodiments, a package with a heat sink separate from a reflective material would fall within the scope of limitation 1.c.

      “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).

      “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. Pet. 25; Ex. 1002 ¶¶ 119– 20 (citing, e.g., Ex. 1005, 7:59–62, Fig. 24); PO Resp. 35–36 (acknowledging Wojnarowski discloses converting an AC input to a DC voltage). 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. 26–27 (citing Ex. 1002 ¶¶ 132–38; Ex. 1008, Abstract (LED voltage “must be matched to the input source voltage”), ¶ 60 (“For AC or any other regularly varying input voltage, there is an additional requirement to direct drive voltage matching”)). 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)).

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).

      “We decline to adopt Patent Owner’s construction because it improperly reads into claim 5 a requirement that the specification and claim language do not support. The specification passages relied on by Patent Owner do not expressly state that a vehicle independent state must be determined while the device is inside a vehicle, and contrary to Patent Owner’s argument, they also do not necessarily imply that. For example, the descriptions of “vehicle independent movement” and “vehicle independent event” in the specification (see Ex. 1001, 1:16, 42) refer to “phone falling to the ground.” “Falling to the ground” implies that the phone may be outside a vehicle, not inside. Further, the specification’s reference to detecting a vehicle dependent state “while also” recognizing a vehicle independent event does not necessarily imply that the vehicle dependent state and vehicle independent event are being detected simultaneously, as Patent Owner argues. In the language of claim 5, a “vehicle independent state” is recited in the determining step (step c), and the requirement that the portable device is located “inside a vehicle” relates to creation of an operation indicator, as part of the detecting step (step b). Patent Owner does not dispute this, and agrees that a portable device “not in the vehicle” can satisfy the determining step (step c). Tr. 73:5–8. Patent Owner, however, argues step c’s recitation that a “vehicle independent state” is based on step b’s “predetermined criteria” creates a link between “vehicle independent state” and step b, and thus an “express requirement” in step c that the device is located inside the vehicle. See Tr. 73:8–26, 76:1–3. We decline to read this requirement into the claim language. Although the claim language states that determining a “vehicle independent state” is based on “predetermined criteria,” and step b describes comparing “predetermined criteria” to an “operation indicator” that is created when the device is inside a vehicle, it does not limit the step of determining a vehicle independent state to a time when the portable device is inside a vehicle.

As we discussed in our institution decision, nothing in the ’185 patent indicates that the definition of bio oil is so limited. And we note that certain dependent claims of the ’185 patent, for example claim 21, specifically recite a pre-treatment step, leading to the conclusion that the bio oils of the independent claims are not limited to only pretreated bio oils. Neste’s new evidence introduced during trial is extrinsic to the patent, based on the testimony of Dr. Klein regarding the criticality of the iron content range. See PO Resp. 3 (citing Ex. 2029 ¶¶ 35–36, 38). In any event, we fail to see how the criticality of the claimed range mandates that the bio oil be pretreated prior to undergoing the claimed process. While Dr. Klein testifies that it is “clear from the ‘185 patent [that] a bio oil feed must be pretreated to render it suitable for commercial hydrotreatment” (Ex. 2029 ¶ 35), the portion of the patent he cites for this proposition states only that “bio-based feedstock (glyceride oil) to be used as feed material for hydrotreatment reaction can be purified to iron content of less than 1 to 0.2 w-ppm.” Ex. 1001, 4:50–55 (emphasis added). But this statement does not address the use of a bio oil that already contains an iron content within the claimed range, which therefore would not need purification. Indeed, the ’185 patent discusses “experiments with palm oil having very low level of impurities.” Ex. 1001, 4:45–46. Based on the foregoing, we maintain our view that the claim term requires no construction beyond its express language. The bio oil to be used in the method of claim 1 may be pretreated to achieve the claimed iron content, but pretreatment is not required by the claim.” slip op. at 11

      “The intrinsic record of the ’185 patent contains no indication that bio oil intermediate was a new term coined to signify a specific class of bio oils, as Neste contends. The written description contains a section devoted to providing specific definitions for terminology, including “bio oil,” “glyceride oil,” and “hydrotreatment.” Ex. 1001, 3:28–4:7. There is no mention of a bio oil intermediate, which would be expected if the inventors had intended to coin a new term. The only use of “intermediate” in the entire written description is as follows: “disclosed is a glyceride oil intermediate, which intermediate consists of glyceride oil from at least one renewable source and the iron content of said glyceride oil is less than 1 w-ppm.” Id. at 4:64–67. The sentence preceding that one states only that the “purification result can be obtained (depending on used feedstock) using pretreatment methods.” Id. at 4:61–62 (emphasis added). As can be seen, there is no mention in this passage that the “glyceride oil intermediate” must be pretreated, and no indication it is a novel term coined by the inventors. In any event, Neste has not given us reason to depart from the general presumption that a claim preamble is not limiting. The body of claim 6 recites a structurally complete invention, defining the bio oil intermediate according to its iron content. There is no reason to rely on the preamble of the claim for any structure, or for antecedent basis for any claim term. Therefore, we conclude that the preamble does not “breathe life and meaning” into the claim, but rather recites an intended use for the structurally complete invention recited in the body of the claim. As such, we decline to adopt Neste’s modified construction of the claim term, and maintain our prior construction of claim 6’s preamble.” slip op. at 14

      “Upon evaluation of the record as a whole, we believe Neste has the better argument, and conclude that the iron content of the bio oil in claim 1 should be determined when the feed is introduced to the catalyst bed. This interpretation is, most importantly, reflected in the structure of the claim. Claim 1 contains a single process step, of “subjecting a bio oil . . . to a hydrotreatment process.” Immediately following this process step is a wherein clause that requires the iron content of “said bio oil” to be within a certain range. The necessary implication of this claim structure is that “said bio oil” is referring to the substance that is being subjected to the hydrotreatment process, meaning the iron content that is relevant to the claim is the iron content at the time of hydrotreatment with a catalyst. The claim, as a comprising claim, does not exclude the presence of other treatment steps such as purification or dilution, but the structure of the claim does imply that these additional steps should be performed prior to determining whether the iron content of the feed is within the claimed range.” slip op. at 20
