“Petitioner contends that one of ordinary skill in the art “would have had at least a Bachelor’s degree in electrical engineering, material science, chemical engineering, or an equivalent field, as well as at least 2 to 3 years of academic or industry experience in the recycling or processing of lithiumion batteries. Additional formal education focusing on processing of lithium batteries may substitute for practical experience and additional practical experience can substitute for less education.” Pet. 10–11. Patent Owner does not contest this definition of a person of skill in the art. See Prelim. Resp. 11. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as, on the present record, it appears consistent with the ’463 patent and the asserted prior art.

“distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony. Weighing this evidence all together, we find that Petitioner has failed to show that it is more likely than not that Tomioka’s teaches the claimed comminution under Petitioner’s first theory.” slip op. at 15

“obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off. Thus, we find that Petitioner has failed to show that it is more likely than not that Tomioka accounts for the claimed “comminuting.”” slip op. at 15

“We are persuaded by Patent Owner that the term “automatically” in “to automatically disengage the first and second catch structures” means that it is not just the force applied by the user that disengages the first and second catch structures, but also the bias of the mouthpiece that helps to disengage the first and second catch structures. In the first instance, we agree with Patent Owner that the claim itself recites that, upon actuation, the mouthpiece assembly is “release[d]” to “move via its bias from the stowed configuration to the dispensing configuration.” See Ex. 1001, 21:59–64. This meaning is supported by the Specification which states: “In some examples, the mouthpiece assembly is biased toward the dispensing configuration and thus moves automatically under its bias upon release by the user-release mechanism.” Ex. 1001, 1:64–67. We further agree with Patent Owner that the plain and ordinary meaning of “automatic” is that the user operation alone is not responsible for the action. For example, in one dictionary cited by Petitioner, “automatic” is defined as “2: having a self-acting or self-regulating mechanism.” See Ex. 2007, 1.11 The district court construction is consistent therewith. The district court identified two functions, the first of which is the same as that of the ’028 patent, i.e., “Automatically disengaging the first and second catch structures upon actuation of the user release mechanism and thereby releasing the mouthpiece assembly to move via its bias from the stowed configuration to the dispensing configuration.” See Section II.C.1, supra. In discussing that function, the district court states: “While a user may impart force upon user engagement portion 260 to release the mouthpiece, the bias of the mouthpiece towards the dispensing configuration causes the mouthpiece to move automatically, satisfying the requirements of Claim 1.” Ex. 2002, 16.

“First, Petitioner’s reason to modify Kiyota “to provide the advantage of a bite actuated mouthpiece” (Pet. 42) does not explain why one would use Choi’s mount 100.

This description suggests that mount 100 is not a required component for a bite-actuated mouthpiece. Our understanding is supported by Patent Owner’s expert, who testified that using Choi’s mount as a “rigid collar member” in Kiyota’s mouthpiece assembly does not require combining its bite-actuated valve because “the bite-actuated portion has nothing to do with the alleged rigid collar member portion.” Ex. 2001 ¶ 119 (citing Ex. 1005 ¶ 46); see also Prelim.

Thus, we deny the Petition and do not institute an inter partes review of claims 1, 2, 5, 6, 8, 9, 15, 16, and 21 of the ’028 patent.” slip op. at 2
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Patent Owner argues that a POSITA would have “a bachelor’s degree in mechanical engineering or the equivalent coursework and approximately one year of experience with liquid-containing devices, with more work experience substituting for less education and vice versa.” Prelim. Resp. 23 (citing Ex. 2001 ¶¶ 56–65). Patent Owner also states that it “discerns no material difference between the definitions provided by the parties for purposes the Board’s decision on whether to institute this proceeding.” Id. We agree that there appears to be no material difference in the parties’ definitions of the level of ordinary skill in the art. For the purposes of this Decision, we apply Petitioner’s definition of the level of ordinary skill in the art. We determine that this definition is consistent with the prior art of record and the skill reflected in the Specification of the ’028 patent, based on our review of the limited record. Moreover, the prior art itself may be sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not” slip op. at 11
- Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for petitioner
“as a means-plus-function limitation under 35 U.S.C. § 112, sixth paragraph, because “mechanism” is a nonce word for performing the claimed function without reciting structure for performing that function, and a POSITA would not have understood the term to have “a sufficiently definite meaning as the name for a structure that performs the claimed function.” Pet. 16–17 (citing Ex. 1003 ¶ 39). For claim 1, Petitioner identifies two distinct structures described in the ’028 patent that correspond to the claimed “user release mechanism” for performing the claimed functions. Id. at 34. Specifically, Petitioner asserts that the ’028 patent describes a first embodiment in which the corresponding structure includes sliding member 238, and its component parts. Id. at 34– 35 (citing Ex. 1001, 12:50–13:25, 13:29–33). In the second embodiment, the corresponding structure includes user engagement portion 260 on rigid collar 170. Id. at 35–36 (citing Ex. 1001, 13:40–54). Petitioner does not separately address the structure corresponding to the “user release mechanism” as recited in claim 21. Id. at 53‒54 (relying on the same arguments presented for unpatentability of claim 1). court issued a claim construction order in the parallel litigation construing the term “user release mechanism” as a means-plus-function limitation under § 112, sixth paragraph. Prelim. Resp. 23 (citing Ex. 2002, 12–15). The district court ruled that the corresponding structure for claim 1 includes “[s]liding member 238, including its component parts,” or “[u]ser engagement portion 260.” Ex. 2002, 15. For claim 21, the district court ruled that the corresponding structure includes “[s]liding member 238, including its component parts” or “[u]ser engagement pad 240, planar portion 242, tabs 244, collar engagement portion 254, depression 256.” Id. at 17. Patent Owner indicates that, “[f]or purposes of this proceeding only,” it does not dispute that the claimed user release mechanisms are means-plusfunction limitations, and it does not dispute the corresponding structure identified by Petitioner, even though the district court did not specifically identify engagement portion 260 as corresponding structure for claim 21. Prelim. Resp. 25 (citing Ex. 2002, 15–19). Although Patent Owner does not dispute Petitioner’s proposed interpretation of the “user release mechanism,” because claim interpretation is a matter of law and the dispositive issue in this Decision turns on the interpretation of this claim limitation, we address it in this Decision. We agree with the parties that the “user release mechanism” elements recited in claims 1 and 21 are means-plus-function limitations governed by § 112, sixth paragraph. See 35 U.S.C. § 112 ¶ 6 (“An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.”). “means,” it uses the nonce word “mechanism” without reciting structure for performing the functions recited in the claims. See Williamson v. CitrixOnline, LLC, 792 F.3d 1339, 1350 (Fed. Cir. 2015) (“Generic terms such as ‘mechanism,’ ‘element,’ ‘device,’ and other nonce words that reflect nothing more than verbal constructs may be used in a claim in a manner that is tantamount to using the word “means” because they ‘typically do not connote sufficiently definite structure’ and therefore may invoke § 112, para. 6.”).” slip op. at 13

“[U]nder § 112, ¶ 6 equivalence, functional identity is required” and “[s]tructural equivalence under § 112, ¶ 6 is met only if the differences are insubstantial, that is, if the assertedly equivalent structure performs the claimed function in substantially the same way to achieve substantially the same result as the corresponding structure described in the specification.” (citing Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308 (Fed. Cir. 1998)). Here, Petitioner states that Kiyota’s lock release buttons 40 “perform the claimed function in the same way to achieve the same result” as the ’028 patent’s sliding member 238, and its component parts (Pet. 37) without providing sufficient supporting explanation or evidence. Petitioner explains only that the two structures operate in “substantially the same way” by a user pressing an element that that slides towards the mouthpiece assembly to disengage the catch structures. Id. at 37–38 (citing Ex. 1003 ¶ 89). The Petition does not discuss any of the differences between Kiyota’s structure and the ’028 patent’s structure or provide an explanation of why these differences are insubstantial. Indeed, as Patent Owner persuasively explains, there are notable differences in the “way” the two structures perform the claimed function and the “result” they achieve. See Prelim. Resp. 39–40 (discussing the ’028 patent’s one-finger operation and indirect catch disengagement, versus Kiyota’s two-finger operation and direct catch disengagement). Moreover, the analysis in Dr. Vallee’s declaration substantially parallels the discussion in the Petition and does not provide any additional explanation or evidence to show that the differences between the “way” the two structures operate or the “result” they achieve are insubstantial. Compare Ex. 1003 ¶¶ 85–91, with Pet. 34–38. For these reasons, Petitioner fails to show sufficiently that Kiyota discloses an equivalent structure to the structure described in the ’028 patent corresponding to the “user release mechanism” recited in claim 1. Accordingly, Petitioner has not met its burden to show a reasonable likelihood that claim 1 is unpatentable as obvious over Kiyota. slip op. at 23

Inter partes review may not be instituted “unless . . . the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314. Upon consideration of the evidence and arguments in the record, for the reasons below, we determine that the information presented does not show a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims.

“person having ordinary skill in the art “would have had at least a four-year degree in a design-based field, which may include fashion design, industrial design, mechanical engineering, or another technical field, or equivalent experience, and familiarity working with child products and/or adjustable products.” Pet. 6–7 (citing Smith Decl. ¶¶ 32–38). Patent Owner does not address Petitioner’s proposed definition, which appears consistent with the record in this proceeding, including the prior art. See GPAC Inc., 57 F.3d at 1579. Furthermore, Patent Owner does not argue that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would understand either the challenged patent or the prior art. For purposes of this Decision, we adopt the definition of the level of ordinary skill in the art proposed by Petitioner.” slip op. at 9

“Based on the current record, we need not construe explicitly the term “at least one thigh support adjuster” because doing so would not change the outcome of the analysis below. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). More particularly, and as discussed below, Petitioner does not show sufficiently how the prior art teaches the structure identified as corresponding to the alleged claimed function. Further, because we deny on the merits (as discussed below), we do not address Patent Owner’s alternative argument that we should deny institution because “Petitioner fails to construe th[is] limitation and otherwise argues for an advisory opinion from the Board on indefiniteness.” Prelim. Resp. 1; see id. at 1–6 (entire argument). 2. “defined by” Limitations 1j and 11l each recite “a first setting, a second setting, and a third setting defined by the adjustable child carrier.” Ex. 1001, 17:38–39 (emphasis added), 19:43–44 (emphasis added). Limitation 6k recites “a first position, a second position, and a third position defined by the adjustable child carrier.” Id. at 18:36–37 (emphasis added). Patent Owner proposes a construction for “defined by” in these limitations. See Prelim. Resp. 12–15.

“Public accessibility “has been called the touchstone in determining whether a reference constitutes a ‘printed publication’ . . . .” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1348 (Fed. Cir. 2016) (quoting In re Hall, 781 F.2d 897, 898–99 (Fed. Cir. 1986)). In Hulu, the Precedential Opinion Panel (“POP”) rejected a petitioner’s argument that a reference necessarily meets “the reasonable likelihood standard for institution where the reference bears conventional markers of publication, such as a copyright date, edition identifiers, publication by a commercial publisher, and the assignment of an ISBN number.” Hulu, Paper 29 at 17. The POP stated: “We do not hold that any particular indicia per se is sufficient at the institution stage. Rather, the indicia on the face of a reference, such as printed dates and stamps, are considered as part of the totality of the evidence.” Id. at 17–18 (citing Nobel Biocare Servs. AG v. Instradent USA, Inc., 903 F.3d 1365, 1377 (Fed. Cir. 2018)). Here, Petitioner provides no citation, no discussion, and no support for its assertion that the Synergy Manual was “published” in “2007.” See Pet. 2. Instead, we are left to assume that Petitioner relies on the text “© BabyBjörn AB, Stockholm, 2007” at the bottom of page 6 of the Synergy Manual. More to the point, Petitioner does not discuss in the Petition any evidence supporting the implicit position that the Synergy Manual was publicly accessible prior to the critical date of the claimed invention.” slip op. at 13

“We agree with Autoscribe’s argument that PayPal Express Checkout does not teach the “providing” steps of independent claim 1 and 25 and the “receiving” step of independent claim 15 for two reasons. First, as we explain in our claim construction analysis above, we decline to adopt M&A Ventures’s proposed construction of the “providing” and “receiving” steps as being limited temporally such that not providing the data token to the payer only occurs “during execution of the token retrieval function.” Instead, we construe the “providing” and “receiving” steps in accordance with their plain and ordinary meanings, which includes giving the negative limitation recited therein (i.e., not providing the data token to the payer) patentable weight, without limiting the occurrence of this negative limitation during execution of the token retrieval function. See supra Section II.A.1. With this construction in mind, step 4 of the PayPal Express Checkout flow run in the sandbox environment plainly sends the Payer ID, which M&A Ventures maps to the claimed “data token,” to the buyer. Ex. 1006, 17, 25–26; see also Pet. 64 (arguing PayPal’s Payer ID teaches the “non-sensitive electronic data token” (emphasis omitted)), 67 (arguing the same). Because PayPal sends the Payer ID to the buyer during the PayPal Express Checkout flow, PayPal provides the data token to the payer and, therefore, violates the negative limitation required by the “providing” and “receiving” steps.” slip op. at 31
