“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

The Board denied institution because the Kim and Vayanos combination did not show that each individual bit indicates a separate time interval, as required by claims 1–12.
RulingsInstitution decision- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“limitation 1.2 because it is more consistent with the claim language and the specification of the ’416 patent. The language “each of the plurality of bits” clearly individualizes the “plurality of bits” and the language “indicates a respective time interval that physical shared channel resources are utilized to signal channels” clearly ascribes to each individual bit the function of identifying a time interval that is separate from the time interval(s) that the other individual bit(s) identify. Petitioner’s claim constriction argument largely ignores the words used in limitation 1.2. Petitioner fails to provide anything to explain how or why the plain meaning of “each” and “respective” in the context of limitation 1.2 could be understood by a skilled artisan to connote something other than the plurality of bits individually identifying a separate and distinct time interval (i.e., a “one-to-one correspondence”). Petitioner similarly does not identify anything from the specification of the ’416 patent that would support deviating from the plain meaning of limitation 1.2. And Petitioner’s reliance on 3M Innovative Properties appears to miss the mark. Pet. Reply 7. In that case, the Federal Circuit held that, when a claim term has an “ascertainable definition in the body of the claim,” their “cases do not support prescribing a more particularized meaning unless a narrower construction is required by the specification or prosecution history.” 3M Innovative Properties Co., 725 F.3d at 1329. Here, however, Patent Owner is not attempting to import a more particularized meaning into limitation 1.2, but to demonstrate that the ’416 specification is consistent with the ascertainable definition of “each” and “respective” within the context of limitation 1.2. In particular, Patent Owner highlights that the ’416 specification describes the resource allocation technique as using an indicator bit, within a plurality of indicator bits, that has a one-to-one correspondence to a specific time window established for a Forward Access Channel (FACH). See Ex. 1001, 13:63–14:25, 14:44–53, Figs. 7, 9; PO Resp. 11–14, 19–20; PO Sur-reply 2–3; Ex. 2001 ¶¶ 36–40, 49. And we agree that the ’416 specification informs, and is consistent with, the plain reading of limitation 1.2. See Ex. 1001, 13:63–14:25, 14:44–53, Figs. 7, 9. Therefore, we determine that the plain and ordinary meaning of limitation 1.2 requires all the plurality of bits to individually identify a separate and distinct time interval that physical shared channel resources are utilized to signal channels.” slip op. at 12

“PICH, which is communicated to Kim’s receiver, has a plurality of bits, the evidence fails to demonstrate sufficiently that each of those bits indicates a respective time interval that physical shared channel resources are utilized to signal channels, as limitation 1.2 recites. As Patent Owner correctly argues, the Vayanos paging indicators use multiple bits to indicate information about a single time interval in a frame, rather having several bits that individually identify a separate and distinct time interval. PO Resp. 39–41 (citing Ex. 2001 ¶¶ 67, 74–75). Vayanos teaches that “[t]he number of paging indicators (Np) in each PICH frame is configurable by the system and can take on a value of 18, 36, 72 or 144,” and that “[e]ach paging indicator is sent in 288/Np consecutive bits in the PICH frame, where 288/Np can take on a value of 16, 8, 4 or 2.” Ex. 1006, 3:26–34. As a result, if there are 18 (Np = 18) paging indicators, 288/NP = 288/18 = 16 (meaning that each paging indicator is 16 bits long), if there are 36 (Np = 36) paging indicators, 288/Np = 288/36 = 8 (meaning that each paging indicator is 8 bits long), if there are 72 (Np=72) paging indicators, 288/Np = 288/72= 4 (meaning that each paging indicator is 4 bits long), and if there are 144 (Np=144) paging indicators, 288/Np = 288/144 = 2 (meaning that each paging indicator is 2 bits long). Ex. 2001 ¶ 66. Each paging indicator (singular) taught by Vayanos includes multiple bits––each paging indicator (singular) has either 16, 8, 4 or 2 bits–– and Vayanos does not disclose or suggest a paging indicator that indicates a time interval with only a single bit. Id. And Petitioner does not cite Kim to show the number of bits used to indicate a time interval; only to show that a UE would receive broadcast information with paging information including paging indicators that identify a time interval in which physical shared channel resources are utilized to signal channels. See Pet. 40–49. Even accepting that the Kim/Vayanos combination discloses a UE receiving a paging indicator that is indicative of a time interval in which a Paging Channel PCH may be found or indicative of whether a frame will include a signaling channel (e.g., PCH) at a specific TTI within that frame, the combination does not disclose or suggest using a paging indicator that is a single bit indicating either of those time intervals. On the contrary, as noted above, Vayanos teaches that all paging indicators consist of multiple bits and, thus, the Kim/Vayanos combination discloses a UE that only receives and uses a plurality of bits to indicate a time interval that physical shared channel resources are utilized to signal channels. This is insufficient to show a reasonable likelihood that Petitioner will be able to establish that the Kim/Vayanos combination discloses or suggests receiving a plurality of bits wherein the individual bits each identify a separate and distinct time interval. Therefore, Petitioner has not shown sufficiently that the Kim/Vayanos combination discloses or suggests the subject matter limitation 1.2 recites. For the above reasons, we are not persuaded that Petitioner has shown sufficiently that the combination of Kim and Vayanos disclose or suggest broadcast information that includes a plurality of bits, wherein each of the plurality of bits indicates a respective time interval that physical shared channel resources are utilized to signal channels. This failing undermines Petitioner’s showing as to independent claims 1 and 7 (in the asserted Grounds 1 and 2) and, as a result, the same deficiency extends through to all of the dependent claims challenged in all of the grounds.4” slip op. at 18

Factor 3 weighs against discretionary denial, but this factor does not outweigh the other factors under the circumstances of this case. Thus, the evidence of record favors exercising our discretion to deny institution of an inter partes review.” slip op. at 19

“patent. See Pet. 1; PO Resp. 43; Pet. Reply 4–5; Pet. Sur-reply 3–4. Patent Owner argues that Petitioner failed to justify the filing of two petitions challenging the same patent, and has not provided a ranking of the petitions or explained the differences between the two petitions. Prelim. Resp. 43 (citing Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019), https://www.uspto.gov/TrialPracticeGuideConsolidated (“Trial Practice Guide”)). Because Petitioner has subsequently ranked this Petition as the first among the two (Pet. Reply 4–5), and because we deny institution based on the Fintiv factors as discussed above, we need not decide whether it was appropriate for Petitioner to file two petitions challenging the ’552 patent.” slip op. at 19

“Based on the preliminary evidence, Petitioner has not shown that Vardi’s radio resource database from the server, which includes unauthenticated third-party information, teaches the claimed “authenticated access point list” transmitted by or received from the server. Petitioner has not cited to any evidence that a list including previously connected access points and unauthenticated third-party data constitutes the ordinary and customary meaning of the term “authenticated access point list.” To the extent that Petitioner is arguing that the term should be construed in a way that departs from its ordinary and customary meaning, Petitioner has not pointed to evidence for such a departure in the intrinsic record, and we are aware of no such evidence. We note that the ’522 patent states, “[b]y way of example, but not limitation,” that an “authenticated access point may include . . . an access point previously connected with [the] end device.” Ex. 1001, 4:33–36. But this does not appear to suggest that a prior connection is sufficient to authenticate the access point in the context of the ’552 patent.” slip op. at 18

“whether to institute an inter partes review. Applying the standard set forth in 35 U.S.C. § 314(a), we may not institute an inter partes review (also “IPR”) 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.” However, institution of inter partes review is discretionary. See Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he PTO is permitted, but never compelled, to institute an IPR proceeding.”). For the reasons stated below, we exercise our discretion not to institute an inter partes review.” slip op. at 2
