“336. The applicant explained that not all combinations of shrink films and light blocking materials are recyclable. Id. at 335. The applicant explained that films can be compatible with PET recycling in two ways, (1) the film can float in water and be separated from PET that sinks in water or (2) the PET films crystallize and “can be recovered with the PET stream.” Id. at 336 (citing “A Resource Document by the Association of Plastic Recyclers (APR)”) (found at Ex. 1002, 323–332) (emphasis omitted).

“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“a first current through one or more output ports of the at least one output port in a first operating mode,” and “is configured to output a second current capable of starting a vehicle engine through the pair of output terminals in a second operating mode.” Ex. 1001, 8:25–34. Claim 21 has similar first and second operating-mode limitations. Id. at 9:40–46. Patent Owner proposes that “[t]he proper construction for ‘first operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a first current through one or more output ports of the at least one output port, and outputting a second current capable of starting a vehicle engine through the pair of output terminals is inhibited.’” PO Resp. 25. Similarly, Patent Owner argues “[t]he proper construction for ‘second operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a second current capable of starting a vehicle engine through the pair of output terminals, and outputting a first current through one or more output ports of the at least one output port is inhibited.’” Id. at 27. Patent Owner asserts that claim differentiation supports its construction because dependent claim 3 recites “a third operating mode for outputting the first current and the second current simultaneously,” and “if the battery pack could output the first current and the second current simultaneously in the first operating mode, then there would be no difference between the claimed first operating mode and the claimed third operating mode.” Id. at 26. We disagree with Patent Owner’s constructions because, as Petitioner explains, they wrongly import current-inhibiting limitations beyond the plain language in the claim. Pet. Reply 1. Nothing in the at-issue language addresses inhibiting current. In addition, the claimed first and third operating modes are still distinct without importing additional limitations because outputting just the first current is sufficient for the first operating mode, but not for the third. In other words, whereas the third operating mode requires simultaneity, the first and second merely permit it. Thus, claim differentiation does not support Patent Owner’s construction. Last, although Patent Owner asserts that its construction “is consistent with the specification,” nothing in the cited passages describes inhibiting current. Prelim. Resp. 26 (citing Ex. 1001, 4:30–33, 5:30–33, 5:58–62). Instead, the specification characterizes the modes solely by what the portable charger “can output,” not what is inhibited. Ex. 1001, 4:30–33, 5:30–33, 5:58–62. Thus, we decline to read the first and second operating modes to require the current-inhibiting features that Patent Owner asserts.” slip op. at 6

“Patent Owner argues the two current paths are not different because Chen’s Figure 1 shows they overlap between the lithium battery and the output control circuit and “only diverge when making the connection to the output control circuit.” PO Resp. 32. We disagree. First, Patent Owner’s argument is based on a claim construction for “different” current paths that we do not adopt for the reasons above. In addition, we agree with Petitioner that Chen shows the claimed different current paths even under Patent Owner’s construction. Pet. Reply 8–12. Specifically, as Petitioner explains, a skilled artisan would recognize that Chen’s physical circuits are depicted in Figures 4–7, rather than in Chen’s Figure 1, which is merely a “block diagram of the principle of present invention.” Id. at 9; Ex. 1006 ¶ 15. Unlike Figure 1, Chen’s Figures 5, 6, and 7 show current paths between the battery and USB outputs, and between the battery and DC multi-gear output, that do not overlap with the high current path shown in Chen’s Figure 4. Pet. 9–12. Based on Petitioner’s analysis and for the reasons above, we agree with Petitioner that Chen teaches the claimed “pair of output terminals coupled to the battery pack and having a current path to the battery pack different from that of the at least one output port to the battery pack.”” slip op. at 10

“Patent Owner asserts one skilled in the art would not have added White’s fuse to Chen because doing so was “unnecessary” given Chen’s built-in relay K1 that already provides protection. PO Resp. 42–43. We disagree because, as Petitioner notes, “the Petition cited ample evidence that both layers of over current prevention provide improved safety and protection to the battery.” Pet. Reply 17 (citing Pet. 31–33); see also, e.g., Pet. 31 (describing “advantageously reduc[ing] the likelihood of damage”), id. at 32 (describing “the additional benefit of a safety fuse along a jumper cable to promptly cut off current in the event of a short circuit” and “more simplified maintenance and repair”). Given Petitioner’s unrebutted rationale, Petitioner has articulated sufficient reasoning with rational underpinning to support the legal conclusion that adding White’s fuse and polarity-protection connector to Chen’s power-supply system would have been obvious to one of ordinary skill in the art. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007). Other than the arguments addressed above, Patent Owner does not additionally challenge Petitioner’s obviousness showing based on Chen and White.

“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

Claim 1 recites a particle that comprises (1) a plurality of crystallites comprising (a) a first composition (i) having a layered α- NaFeO2-type structure and (ii) comprising lithium, nickel, and oxygen; and (2) a grain boundary between adjacent crystallites of the plurality of crystallites and comprising (a) a second composition (i) having the layered α-NaFeO2-type structure, a cubic structure, or a combination thereof, and (ii) a concentration of cobalt in the grain boundary greater than a concentration of cobalt in the crystallites. The plain language of claim 1 thus indicates that the grain boundary has a composition (i.e., a “second composition”) distinct from that of the adjacent crystallites (i.e., a “first composition”), and that the grain boundary may have the same structure (i.e., a layered α-NaFeO2-type structure) or a different structure (i.e., a cubic structure, or a combination of a cubic structure and a layered α-NaFeO2-type structure) than the adjacent crystallites. The plain language of claim 1 thus structurally distinguishes the grain boundary from the adjacent crystallites by specifying that the grain boundary has a concentration of cobalt greater than that of the concentration of cobalt in the crystallites.” slip op. at 9

“Petitioner, however, does not provide any evidence to establish that any such identity of empirical formulas means that Lampe-Onnerud’s cathode material necessarily has the same microstructure as the particle of claim 1. In particular, even if the empirical formula of Lampe-Onnerud’s core material is the same as that of the ’317 patent’s first composition, Petitioner does not provide evidence establishing that it necessarily follows that Lampe-Onnerud’s core is a polycrystalline material having a plurality of crystallites separated by grain boundaries between adjacent crystallites. Nor does Petitioner provide evidence establishing that it necessarily follows from any identity between the empirical formula of Lampe-Onnerud’s coating material and the ’317 patent’s second composition that Lampe-Onnerud’s coating material necessarily is present in grain boundaries at a higher concentration than in crystallites, assuming that Lampe-Onnerud’s material is comprised of a plurality of crystallites having grain boundaries between adjacent crystallites. Furthermore, although Petitioner’s declarant, Dr. Aurbach, indicates that Lampe-Onnerud’s process “begins with a conventional lithium nickel oxide-base material . . . known to be comprised of secondary articles having agglomerated primary particles and grain boundaries,” Dr. Aurbach does not provide any objective evidence to substantiate this asserted knowledge in the art. Ex. 1002 ¶ 110. We, therefore, accord little weight to Dr. Aurbach’s opinion on this issue. 37 C.F.R. § 42.65(a) (opinion testimony that does not disclose underlying facts or data “is entitled to little or no weight”); Velander v.

“Further, we interpret claim 14, for purposes of this Decision, as contemplated by Petitioner such that the first and second types of signals may be the same type of signal. Pet. 26. In other words, the first and second type of signal may both be ground or power. This construction appears to have support within the ’885 patent. For example, the ’885 patent describes an embodiment where “at least two conductive portions . . . of the guide 40 are electrically connected to each other by means of a conductive track 39 in the guide, so as to be able to electrically connect to each other groups of contact elements apt to carry a same type of signal.” Ex. 1001, 16:49–59. This construction also appears consistent with parent claim 1, which recites “the first and second types of signals chosen between ground signals and power signals.” The parties are invited to address any claim construction issues during the course of trial.” slip op. at 9

“In an inter partes review, we apply the same claim construction standard as would be used by a district court to construe a claim in a civil action involving the validity or infringement of a patent. 37 C.F.R. § 42.100(b). Under that standard, claim terms are given their ordinary and customary meaning, as would have been understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history of record.

Ltd., 851 F.3d 1270, 1274 (Fed. Cir. 2017). Petitioner invites the same error the Federal Circuit identified in Nidec, where the Board erred by holding that “anticipation can be found even when a prior art reference fails to disclose a claim element so long as a skilled artisan reading the reference would ‘at once envisage’ the claimed arrangement.” Id. (citing Kennametal, Inc. v. Ingersoll Cutting Tool Co., 780 F.3d 1376, 1381 (Fed. Cir. 2015)).

“Petitioner’s obviousness challenge relies on the same argument and evidence that it presents for anticipation of claim 1. Pet. 26 (section VII.A.1.iv addressing anticipation and the micro-controller limitation of claim 1); Pet. 50, 60, 71 (cross-referencing section VII.A.1.iv for obviousness challenge to independent claims 1, 10, and 18). The Petition presents reasons to combine Mieth and Balogh. Pet. 51–55. But Petitioner’s obviousness rationale does not modify Mieth’s load 20, which remains Pet. 52 (relying on “load 20 of Mieth” as part of the combination with Balogh). The Petition presents no rationale for modifying or replacing Mieth’s load 20 and presents no argument or evidence that it would have been obvious to modify Mieth’s circuit by adding or substituting a micro-controller. In short, the Petition and Holberg Declaration assert that the micro- controller limitation is expressly disclosed in Mieth and do not present or support any obviousness rationale for that limitation. Pet. 26, 50–55; Ex. 1007 ¶ 105. Petitioner presents a new theory of unpatentability in the Reply, arguing that “the differences between Mieth’s ‘load 20’ and the claimed micro-controller are such that the subject matter as a whole would have been obvious to a [POSITA].” Pet. Reply 11–19 (reformatted). More particularly, Petitioner argues that “a [POSITA] understands that a micro-controller is a typical type of load that could be substituted into and replace whatever type of load is being employed by Mieth.” Id. at 17 (citing Exs. 1012, 1014, 1022).
