“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.

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.

“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.

“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.

This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery.

Claim 1 recites “a driver, wherein the driver includes at least one transistor and at least one capacitor” and “the driver is configured to receive an AC voltage from a mains power source and provide a voltage and current to the at least one LED circuit.” Ex. 1001, 23:16–17, 26:22–24. Dr. Ducharme testifies that power is determined by multiplying voltage and current. Ex. 2008 ¶ 63.

The Specification provides “the driver providing an AC voltage and current to one or more LED circuits.” Ex. 1001, 3:65–67.

“We begin with the claim language itself which is “the package is a heat sinking reflective material.” Ex. 1001, 23:18–19 (emphasis added).

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). 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

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)).

“35 U.S.C. § 311(b). PO Resp. 22–25. 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

“lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient.” In our institution decision, we determined that this claim language “refer[s] to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” Dec. 10–12. Neither party disputes this interpretation. See PO Resp. 19; Pet. Reply 5–6. Consistent with claim 63’s express comparison between the immunogenicity of the claimed humanized antibody and that of its non-human parent, the Specification states that one object of the invention is to “to provide methods for the preparation of antibodies which are less antigenic in humans than non-human antibodies but have desired antigen binding and other characteristics and activities.” Ex. 1001, 4:24–28. The Specification similarly states that embodiments within the scope of the claims have “low immunogenicity,” or are designed to “minimize the potential immunogenicity of the resulting humanized antibody in the clinic.” Id. at 52:54–58, 61:56–61. Moreover, with reference to claim 63 in particular, Patent Owner points to the ’272 application as “explain[ing] that the purpose of humanizing antibodies using its consensus sequence approach is to reduce immunogenicity versus the non-human parent antibody.

Indeed, we have been directed to no persuasive evidence that a mixture of CO2 and a fluoroalkene of claim 1 has ever been used commercially, or that such a mixture was considered by those of ordinary skill in the art to have met a long felt but previously unresolved need.9, 10 See Tr. 51:24–52:7; Pet. Reply 9 (asserting that Patent Owner “has provided no evidence, post- or pre- issuance of the ’808 patent, of the commercial advantages or uses of the claimed compositions”). With respect to Petitioner’s prior patent applications, although Patent Owner initially characterizes these applications as relating to CO2 and partially fluorinated hydrocarbons, Patent Owner later notes that these patents are directed to blends of HFO-1234yf, CO2, and R-134a. PO Resp. 44; Ex. 2024, 12 (arguing in support of patentability that “[t]he specific 9 To be relevant, Patent Owner must show that the asserted secondary considerations are attributable to “the merits of the claimed invention beyond what was readily available in the prior art.” Asyst Techs. v. Emtrak, Inc., 544 F.3d 1310, 1316 (Fed. Cir. 2008). Here, Inagaki discloses using compounds within the scope of claim 1 of the ’808 patent as refrigerants. Patent Owner presents no persuasive evidence that the addition of CO2 to the compounds of Inagaki, or the particular ranges recited in claim 1, resulted in a product that met a long felt but unresolved need or resulted in a commercially successful product beyond what was provided in Inagaki. Thus, we are also not persuaded that there is any nexus between the asserted secondary considerations and the features of claim 1 that are not disclosed in Inagaki. 10 As Patent Owner has not demonstrated any commercial use of the claim 1 compounds for any purpose, or provided evidence that those of skill in the art considered the claimed compounds to have met an unresolved need in the art, this analysis applies equally to the dependent claims of the ’808 patent, which each depend, directly or indirectly, from claim 1. combination of trans-R1234ze and R134a and CO2 simply is not suggested in Singh, let alone in the amounts defined in claim 1”). Patent Owner does not explain sufficiently why Petitioner’s arguments directed to the patentability of a blend of three compounds, utilized in specific proportions, are necessarily applicable to the combination of Kruse, Inagaki, and Butler proposed by Petitioner, or why these arguments are otherwise strong evidence of the nonobviousness of claim 1 of the ’808 patent. Based on the foregoing, and upon review of Patent Owner’s arguments as a whole, we are not persuaded that Patent Owner’s proffered objective evidence of nonobviousness is strong or tends to refute Petitioner’s arguments and evidence with respect to the obviousness of claim 1 of the ’808 patent.” slip op. at 25
