- Expert testimonyPetitioner expert discountedDecided for patent owner
“We are not persuaded, on this record, that Petitioner adequately establishes that Khatibi discloses a CTE in the claimed range of 16 to 22 µm/(m·°C.). Petitioner’s argument that Khatibi’s reported values meet this claim limitation are based solely on Dr. Randall’s testimony that Khatibi’s measurement method would produce results that would not significantly differ from results determined using the claimed method. See Pet. 16–18 (citing Ex. 1003 ¶¶ 56–60). Dr. Randall’s testimony, however, is largely conclusory and unsupported by adequate explanation and/or objective evidence. For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added). to little weight. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Xerox Corp. v.

Mova Pharm. Corp., 225 F.3d 1306, 1311 (Fed.

“second surfaces of the electrolytic copper foil ranges from 3 to 92.” Ex. 1001, 13:62–63. Petitioner contends that “Kim teaches that the electrolytic copper foil (e.g., untreated or treated copper foil) having Rz less than 2 µm is advantageous toward battery efficiency and performance,” and, similarly, Griesi describes the use of untreated electrolytic copper foil with an Rz value less than 2 µm in printed circuit boards that are compatible with secondary batteries. Pet. 58–59 (citing Ex. 1012, claim 2, ¶¶ 13, 25, 27; Ex. 1003 ¶ 157). In particular, Petitioner notes that Griesi’s Figure 3.16 describes an “Rz value of 1.2 µm.” Id. at 59 (citing Ex. 1015, 53–54; Ex. 1003 ¶ 158). Petitioner asserts that “Dr. Randall explains that a POSITA would have also recognized another surface roughness-related parameter, Rpc, in Griesi as a potentially useful parameter that can be optimized to further enhance uniformity or generally improve Kim’s copper foil surface, for example, to prevent wrinkles or achieve other advantageous effects.” Id. (citing Ex. 1003 ¶ 159). Although Dr. Randall demonstrates that Griesi’s Pc (or Rpc) value is 19.2 over a 4 mm sampling length (Ex. 1003 ¶ 155), Petitioner does not contend that Griesi addresses this value, or indicates any benefit that might be derived from its use. Instead, Griesi’s Pc value appears to be an incidental finding, which is not discussed or analyzed in the reference. See incidental, unexamined finding would lead a POSITA to import Griesi’s Pc value into Kim’s copper foil, absent a hindsight desire to reconstruct the claimed invention. As such, Petitioner’s arguments with respect to Kim and Griesi are not persuasive. See Cheese Sys. Inc. v. Tetra Pak Cheese and Powder Sys., Inc., 725 F.3d 1341, 1352 (Fed. Cir. 2013) (“Obviousness cannot be based on the hindsight combination of components selectively culled from the prior art to fit the parameters of the patented invention.” (internal quotations marks omitted)).

“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

“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. 42 (citing Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019), https://www.uspto.gov/TrialPracticeGuideConsolidated (“Trial Practice Guide”)). Petitioner responds that its “ranking and explanation was at least implicitly included in the Petition.” Prelim. Reply 4. According to Petitioner, the IPR2024-01369 petition “covers all of the claims identified in Patent Owner’s Infringement Contentions” in the parallel district court proceeding. Id. at 4–5. Thus, the present Petition “ranks second, because it covers claims that have not been asserted against Petitioner in the [parallel district court proceeding].” Id. at 5. Petitioner also notes that the claims asserted in this proceeding “focus on the perspective of a server or access point,” whereas the claims in IPR2024-01369 are from the perspective of an end device.

“Based on the preliminary record, it is highly likely that issues bearing on the patentability of the challenged claims will be considered and resolved before we would issue a final written decision. Thus, we determine that the second factor weighs heavily in favor of discretionary denial of the Petition.” slip op. at 12

The Board denied institution of IPR challenging claims 1–17, exercising § 314(a) discretion under Fintiv, chiefly because trial would precede the Board’s final decision and issues substantially overlapped.

“the Fintiv factors. We take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv, Paper 11 at 6. As discussed above, only Factor 3 weighs against discretionary denial, Factor 1 is neutral, and Factors 2, 4, and 5 weigh in favor of discretionary denial of institution, with Factor 2 weighing heavily in favor. Moreover, Petitioner has not persuasively shown, on this record, that its submitted “Sand” stipulation does much to guard against overlap with its district court invalidity arguments under Factor 4, and likewise, the Petition does not show that the merits of its patentability challenges are particularly strong under Factor 6. Accordingly, we determine that the evidence of record favors exercising our discretion under 35 U.S.C. § 314(a) to deny institution of an inter partes review.” slip op. at 18
