    “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)). Thus, we are not persuaded, on this record, that the combined disclosures of Kim and Griesi teach all of the elements of limitation [1g].” slip op. at 23

Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A.

Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein. Ex. 1007 ¶ 52. Petitioner’s expert, Dr. Shealy states that he understands paragraph 52 to mean that it is “fair game to pull the recess out of any of those figures [Figures 1A through 6].” Ex. 2004, 39:12–21. Dr. Shealy, however, also clarifies that “[a]s I said before, I think you could take all the embodiments and bring in which ones you want, depending on what you’re trying to accomplish.” Ex. 2004, 40:24–41:1. During the hearing, Petitioner admitted that Dr. Shealy’s “statement to modify the reference depending on what you're trying to accomplish” means that “a POSITA may modify with reason to do so. A POSITA would have removed Saxler’s recess to obtain the benefits of enhancement-mode.” Tr. 19:19–25. Again, the Petition does not provide a reason why a POSITA would have removed Saxler’s gate recess.” slip op. at 28

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for petitioner

    “In the Institution Decision, we declined to adopt Petitioner’s proposed construction of the “side surfaces” limitation and determined that it was not necessary to further construe this term because “[t]he parties do not dispute that the language ‘side surfaces extending horizontally’ encompasses a gate material with sloped side surfaces as depicted in Figure 5 of the ’335 patent.” Inst. Dec. 11–16 (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). We invited the parties to address this limitation further during the course of this trial, but neither party provided additional evidence or argument regarding the “side surfaces” limitation. Inst. Dec. 16; see generally PO Resp.; Reply; Sur-reply. Accordingly, we maintain our determination from the Institution Decision that we do not need to construe the “side surfaces” limitation. Inst. Dec. 15– 16.” slip op. at 14

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

    “This evidence, particularly the language in the ’335 patent itself, undermines Patent Owner’s argument that “[t]he process for forming gate ledges using separate masks instead of the self-aligned process disclosed in the ’335 patent cannot produce ledges that are ‘substantially symmetric.’” PO Resp. 39 (emphasis added); see also PO Resp. 42–43 (arguing that a gate structure with ledges having substantially equal widths is “not achievable” without using a single photo-mask process). We have considered the evidence presented by Patent Owner and Dr. Schubert in support of Patent Owner’s arguments. PO Resp. 38–43; Ex. 2005 ¶¶ 49–51. We, however, are unable to discern sufficient evidence supporting a conclusion that using separate masks cannot produce ledges that are substantially symmetric, particularly when the ’335 patent suggests otherwise. See Ex. 1001, 4:60– 63 (referring only to the “possibility of misalignment”). Even if, as Patent Owner and Dr. Schubert contend, misalignment “naturally” occurs when using a two-mask process, that does not foreclose the possibility that the” slip op. at 18

    “and Trademark Office under 37 C.F.R. § 42.4(a), we may only institute an inter partes review when “the information presented in the petition . . . and any response . . . 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(a); see also 37 C.F.R. § 42.108(c). However, institution of inter partes review is discretionary. See Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed.

  • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Institution denied fintivDenied

    “A holistic balancing of the Fintiv factors weighs in favor of discretionary denial of the Petition. As discussed above, factor 2 weighs heavily in favor of discretionary denial because the district court is likely to address patentability issues at trial before we would issue a final written decision. Factor 4 weighs in favor of discretionary denial, as does Factor 5 at least to some degree. Factors 1 and 6 are neutral. 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

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.

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Other

    “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
