      “In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. 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. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

      “II. STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may be determined “if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors.” Arnold Partnership v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004) (citing In re 1 US 2013/0108922 A1, published May 2, 2013 (Ex. 1004, “Shinozaki”). 2 G. Khatibi, Temperature Dependent Elastic and Thermal Properties of Thin Copper Foils, Copper; Proceedings of the International Conference Copper ’06 (2006) (Ex. 1006, “Khatibi”). 3 Korean Patent Pub. No. 10-2012-0003485, published Jan. 10, 2012 (Ex. 1013; Ex. 1014 (English translation), “Toshio”). 4 US 2013/0108887 A1, published May 2, 2013 (Ex. 1012, “Kim”). 5 Griesi, M.B., Characterization of Electrodeposited Copper Foil Surface Roughness for Accurate Conductor Power Loss Modeling (2014) (Master’s Thesis, University of South Carolina) (Ex. 1015, “Griesi”). rehearing has the burden to show that the decision should be modified. 37 C.F.R. § 42.71(d). Additionally, the request for rehearing “must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed in a motion, an opposition, or a reply.” Id.” slip op. at 2

      “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

      “Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”). It was Petitioner’s burden to establish that the combined teachings Kim and Griesi disclose limitation [1g] as proposed. We are not persuaded that we misapprehended Petitioner’s argument when we determined that Petitioner did not meet that burden.” slip op. at 8

      “connotes interactivity, and does not explain why a “Data Animation Effect” would be interactive.6 These aspects of Figure 53 do not appear to show interactivity. Thus, the issue is whether selecting a choice other than “Hide” for “Scroll buttons” in box 710 of Figure 53 adds to chart 840, once published, a feature that allows a user to interact with that chart via scrolling, or whether “Scroll buttons” refers to some other feature of the configuration process (such as the scroll buttons shown in Figure 53 for scrolling through the various charts in the layout). Both experts provide conclusory testimony stating how they view Figure 53. Ex. 1003 ¶ 181 (“For example, Figure 53 of Rostoker shows the ‘Configure Chart View’ toolbar, which includes multiple ‘interactive’ features, such as making the chart ‘Selectable’ (suggesting interactivity using an input device such as a mouse), including ‘Scroll buttons’ to scroll the chart, and adding ‘Data Animation[s].’”); Ex. 2001 ¶ 141 (“Schmandt relies on the ‘Configure Chart View’ toolbar of FIG. 53 of Rostoker, but he is confusing the configuration step 330 of Rostoker with the end result.”).

      “We agree with Patent Owner. At most, Jou teaches that it was known to interact with charts in a Windows environment or a browser window. Ex. 1007 ¶ 34. But Rostoker already teaches that a user could interact with a chart, via a graphical user interface in a web browser, while configuring the chart. Ex. 1005 ¶¶ 67–75. Petitioner does not explain persuasively why a skilled artisan, per the teachings of Jou, would have made Rostoker’s published charts interactive. Mr. Schmandt’s testimony that a skilled artisan “would have been motivated to incorporate Jou’s additional ‘interactive’ features into Rostoker’s system to enable users to better visualize and explore business data,” is not supported by his citations to Jou, at least as to whether a skilled artisan would have modified Rostoker’s published charts. Ex. 1003 ¶ 259 (citing Ex. 1007 ¶¶ 8, 9). Petitioner’s argument that Flash and Java could enable interactive features, at most, show that a skilled artisan could have implemented interactive features with Rostoker’s a reason why a skilled artisan would have made these modifications.

      “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. Bytemark, Inc., IPR2022-00624, Paper 12 at 5 (PTAB Feb. 10, 2023) (finding that “the Board was correct in giving little weight to Petitioner’s expert because the expert declaration merely offered conclusory assertions without underlying factual support”); Upjohn Co. v. Mova Pharm. Corp., 225 F.3d 1306, 1311 (Fed. Cir. 2000) (“Lack of factual support for expert opinion to factual determinations, however, may render the testimony of little probative value in a validity determination.” (quoting Ashland Oil, Inc. v. Delta Resins and Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985))); see also In re Ethicon, Inc., 844 F.3d 1344, 1348, 1352 (Fed. Cir. 2017) (concluding that the Board properly gave “little weight” to conclusory expert testimony of objective indicia). Because Petitioner offers Dr. Randall’s testimony to supply a limitation missing from the prior art, namely, the CTE measurement method, and we give Dr. Randall’s unsupported and conclusory testimony little weight, we are not persuaded that Petitioner establishes a reasonable likelihood of showing that Khatibi discloses limitation [1d].” slip op. at 17

      “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

Petitioner further argues that “[a]dditonal experience can substitute for the level of education, and vice-versa.” Id. (citing Ex. 1003 ¶¶ 60–63). Petitioner also identifies knowledge that a person having ordinary skill in the art would have. Id. at 25–26 (citing Ex. 1003 ¶ 64). Patent Owner states that it “has applied Petitioner’s [person having ordinary skill in the art] for the sake of this Response.” Prelim. Resp. 21. Because Petitioner’s proposed level of ordinary skill in the art is consistent with the field of the invention of the ’991 patent and not disputed by Patent Owner, we adopt Petitioner’s formulation of the person having ordinary skill in the art.” slip op. at 8

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “Based on the ordinary meaning of the phrases, “spatial samples” and “spatial information” must refer to different information. Because the “spatial samples [are] decoded into spatial information,” the decoded “spatial information” must be different than the coded “spatial samples.” If “spatial information” were the same as “spatial samples,” then there would be nothing to decode. That construction is consistent with the claim construction rule that different terms are presumed to have different meanings. See MicroStrategy Inc. v. Bus. Objects Ams., 238 F. App’x 605, 609 (Fed. Cir. 2007) (citing CAE Screenplates Inc. v. Heinrich Fiedler GmbH & Co. KG, 224 F3d 1308, 1317 (Fed. Cir. 2000) (“In the absence of any evidence to the contrary, we must presume that the use of these different terms in the claims connotes different meanings.”); Applied Med. Res. Corp. v. U.S. Surgical Corp., 448 F.3d 1324, 1333 n.3 (Fed. Cir. 2006) (“[T]he use of two terms in a claim requires that they connote different meanings . . . .”)). Here, we see no evidence that the claim phrases have the same meaning. To the contrary, the ’991 patent uses the term spatial samples to refer to the image’s pixel values. See, e.g., Ex. 1001, 2:65–67 (“the prediction error signal for a single image block is constructed using both transform basis functions and spatial samples (i.e., pixel values)”) (emphasis added); id. at 4:21–26 (same). The spatial information, however, refers to the result of decoding. See, e.g., id. at 3:29–30 (“the plurality of spatial samples are decoded into decoded spatial information”) (emphasis added); id. at 6:53–55 (“the decoded spatial information and reconstructed prediction of the image block are added together to form the decoded representation of the image block”) (emphasis added); id., Fig. 5, 520 (showing “Decoded Spatial Info”). This is consistent with the claim’s plain language. See id. at 10:1–2 (claim 22 reciting “decoding, by a processor, the plurality of spatial samples into decoded spatial information”) (emphasis added). Accordingly, “spatial samples” and “spatial information” do not refer to the same thing.” slip op. at 9

      “We are not persuaded by Petitioner’s argument. Petitioner maps both spatial samples and spatial information to the residual of the prediction error. Compare Pet. 37 (referring to spatial samples as the residual of the prediction error), with id. at 44 (referring to spatial information as the residual of the prediction error). However, because spatial samples and spatial information cannot refer to the same thing, they cannot both be the residual of the prediction error. See Section II.C.1 supra. Accordingly, Petitioner has not sufficiently shown that claim 22, along with dependent claims 23, 24, 26, and 30 would have been obvious over Koga. See In re Fritch, 972 F.2d 1260, 1266 (Fed. Cir. 1992) (“[D]ependent claims are nonobvious if the independent claims from which they depend are nonobvious.”); Pet. 47–63 (relying on the analysis of claim 22 for the spatial samples and spatial information limitations). With regard to independent claim 31, along with dependent claims 32, 33, and 35, Petitioner relies on the same arguments discussed above for limitation 22a and 22c to show that Koga teaches commensurate limitations 31c and 31d. See Pet. 54 (“As explained above, Koga teaches the shared substantive limitations of [22a]–[22d] (supra §§VI.A.1) that correspond to limitations [31b]–[31e].”). Accordingly, for the same reasons discussed above for claim 22, we are not sufficiently persuaded by Petitioner’s arguments that independent claim 31, along with dependent claims 32, 33, and 35 would have been obvious in view of Koga.” slip op. at 16

      “only to the extent necessary to resolve the controversy. Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). In Patent Owner’s view, “the claims require sharing ESD charge from one pad with a different I/O pad.” Prelim. Resp. 27. Patent Owner argues that charge sharing is the only way that charging the pad capacitance can reduce a maximum voltage, as recited. Id. at 24–25. Apart from the charge sharing, Patent Owner argues that the recited enable or control circuitry is not located in the circuit where the ESD event occurs. Id. at 27–33. Patent Owner argues that Petitioner disagrees with this interpretation. Id. Petitioner, though, argues that it would have been obvious to duplicate Verhaege’s and Ker’s protection circuits. See, e.g., id. at 18 (discussing claim 1 and Verhaege), 48 (discussing the Verhaege-Miller combination), 66 (discussing claim 1 and Kerr). For example, Petitioner argues that “a POSITA would have been motivated to use the improved protection circuit of Verhaege, apply it at every I/O pad, and share the ESD energy across multiple pad circuits as taught by Miller.” See id. at 48 (emphasis added). From statements like these, Patent Owner draws the conclusion that Petitioner must also be interpreting the claims to require charge sharing. Prelim. Resp. 25–27. For the reasons discussed in Section II.C below, Petitioner has not shown a reasonable likelihood of showing that any claims are unpatentable even under the implied claim construction used in its obviousness rationale. The Board need not expressly construe any claims in reaching that conclusion.” slip op. at 6

      “Petitioner argues, “It would have been obvious to a POSITA that, because an ESD event could occur at any I/O pad, the Verhaege invention should be repeated at every I/O pad.” Pet. 18 (citing Ex. 1002 ¶ 67); id at 30–32 (claim 6); id. at 43 (claim 14). Yet Petitioner acknowledges that “there were many obvious ways to activate multiple circuits during an ESD event.” Id. at 51. The Petition does not sufficiently explain why it would have been obvious to have chosen the way that is claimed. See id. at 18, 30– 32, 43. Rather, Petitioner’s obviousness rationale appears to be based on impermissible hindsight gleaned entirely from the challenged patent’s 1327, 1351 (Fed. Cir. 2014) (“It appears that [the expert] relied on the . . . patent itself as her roadmap for putting what she referred to as pieces of a ‘jigsaw puzzle’ together.”).
