Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator.

    “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[6] 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).” slip op. at 4

    “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.

    “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)).

Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (noting that the prior art itself may reflect an appropriate level of skill in the art). We note, however, that the open-ended language “at least” expands the range of education and experience indefinitely with no upper bound. Therefore, we do not adopt this aspect of Petitioner’s formulation.” slip op. at 8

    “Based on the record before us, we do not find it necessary to expressly construe any claim terms or phrases to reach our decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (per curiam) (claim terms need to be construed “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.

    “First, even under Petitioner’s assertion that “controller RG . . . performs the functions of an error amplifier and amplifier output stage” (id. at 37), Petitioner has not adequately shown that controller RG meets all three of “an error amplifier,” “a control voltage,” and “an amplifier output stage.” Petitioner’s assertions that those elements are “interior to” or “include[d]” in controller RG are conclusory and unsupported. Petitioner summarizes and reproduces portions of Sudhaus regarding the output currents of controller RG, but has not explained the relevance of its summary and reproduction with respect to each recited claim element. See id. at 37–38 (citing Ex. 1005, 2:32–33, 4:25–28, 4:46–50, 8:47–55), 40– 41. Nor has Petitioner explained why or how the summarized or reproduced portions of Sudhaus show that those claim elements are interior or included in controller RG. See id. Further, Petitioner also fails to show how Sudhaus teaches the claimed interactions and relations between the error amplifier, control voltage, and amplifier output stage. The claim recites the error amplifier compares voltages to “generate a control voltage” and the amplifier output stage controls output current “based on the control voltage.” Petitioner has not explained what specific signal controller RG generates that teaches a “control voltage” used to control output current. Nor has Petitioner stated, let alone explained how, controller RG generates a control voltage in the claimed manner and controls output current based on that control voltage. Simply because controller RG produces outputs that are allegedly similar to the claimed outputs does not by itself show that controller RG produces the claimed outputs using the claimed elements in the claimed manner.” slip op. at 16

Notably absent, however, from the above-identified portions of the Petition and testimony of Dr. Bookstein is any reference to material that is “trimmed away” or why any such material is regarded as surrounding a textile element, or any other component of Clark. In a later portion of the Petition addressing the second clause of limitation 1a, Petitioner makes reference to Clark’s column 4, lines 61 through 66, as disclosing a “trimming process.” Pet. 23–24 (citing Ex, 1003 ¶ 128). That portion of Clark generally expresses that “the exposed edge of the upper may be trimmed in any desired outline . . . and the trimmed edge may be bound or finished as desired.” E. 1004, 4:61–66. We agree with Patent Owner that, to the extent Petitioner and Dr. Brookstein rely on that portion of Clark to account for the first clause of limitation 1a, Petitioner does not meaningfully explain why Clark’s disclosure of “the potential trimming of an ‘exposed edge’ (singular)” of any textile element means that the textile element is regarded as “hav[ing] been knitted with a surrounding textile structure.” See Prelim. Resp. 15–16 (citing Ex. 2003 ¶ 38). We credit Dr. Pastore’s testimony to that end, over that of Dr. Brookstein (see, e.g., Ex. 1003 ¶ 128), as we find that Dr. Pastore’s testimony is more consistent with Clark’s actual disclosure and what it would have conveyed to one of ordinary skill in the art.” slip op. at 19

    “B. Level of Ordinary Skill in the Art In determining the level of skill in the art, we consider the type of problems encountered in the art, the prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field. Custom Accessories, Inc. v. Jeffrey-Allan Indus. Inc., 807 F.2d 955, 962 (Fed. Cir. 1986); Orthopedic Equip. Co. v. U.S., 702 F.2d 1005, 1011 (Fed. Cir. 1983). Petitioner contends the following assessment in connection with a person of ordinary skill in the art: The Challenged Claims pertain to a method of recovering geothermal heat. However, “[m]any of the techniques are derived from oil and gas industry.” EX1001 at 4:23-24. Accordingly, here, a person of ordinary skill in the art (“POSITA”) is a person with a Bachelor’s degree, Master’s degree, and/or Ph.D. in Chemical Engineering, Petroleum Engineering, Energy Resource Engineering, or the like, or at least five years of experience engineering, drilling, and constructing wells. Furthermore, a person with less formal education but more experience, or more formal education but less experience, could also have met the relevant standard for a POSITA. Pet. 16–17 (citing Ex. 1004 ¶¶ 34–36). Patent Owner does not offer its own assessment of a POSITA. For purpose of this Decision, we adopt Petitioner’s assessment.” slip op. at 9

Resp. 17 (citing Samsung Electronics Co., Ltd. v. Power2B Inc., IPR2022-01378, Paper 12 at 11 (PTAB Mar. 15, 2023) (citing Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed.

Patent Owner further submits that “[u]nder Rule 104(b)(3),[14] Petitioner had an obligation to provide a construction of claim element 9c that includes both the claimed function and the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.” Id. We agree with Patent Owner that the term “means for” when appearing in a claim triggers a rebuttable presumption that treatment under § 112 applies. On the record before us, however, Petitioner has not explained why the noted presumption has been rebutted or does not apply, and has not provided a construction of the pertinent “means for” term in the Petition in contradiction to the requirements of 37 C.F.R. § 104(b)(3).” slip op. at 10

  • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightNot shown unpatentableNot shown unpatentable

    “While it is certainly the case that “a prior art reference is relevant for all that it teaches to those of ordinary skill in the art,” see In re Fritch, 972 F.2d 1260, 1264-65 (Fed. Cir. 1992), it is incumbent on a petitioner, in advancing a permissible theory of obviousness, to explain why a skilled artisan would recognize to pick and choose certain aspects of a reference and combine them with other aspects of the reference, particularly so where the reference itself does not suggest such combination. See In re Hedges, 783 F.2d 1038, 1041 (Fed. Cir. 1986) (“It is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position, to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests” ) (citation and inner quotes omitted). Here, Petitioner’s oscillation between different embodiments of Rinaldi in an attempt to reach the requirements of claim 1 is not adequately explained, and more closely resembles impermissible hindsight. See Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017). (“[W]e cannot allow hindsight bias to be the thread that stitches together prior art patches into something that is the claimed invention.”). In sum, we determine that Petitioner has not shown a reasonable likelihood of prevailing in its assertion that claim 1 is unpatentable as a part of Petitioner’s proposed Ground 1.” slip op. at 18
