    “B. Level of Ordinary Skill in the Art As noted above, resolving the question of obviousness requires determination of the level of ordinary skill in the art. Graham, 383 U.S. at 17–18. Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner. The absence of such assessment calls into question the fundamental adequacy of Petitioner in carrying its burden to show a reasonable likelihood of success of unpatentability of the challenged claims that necessarily must take into account the level of ordinary skill in the art.” slip op. at 10

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

    “Stated somewhat generally, the core question underlying Patent Owner’s challenge to Petitioner’s Fukui-based grounds is whether a conversion module (e.g., 20) that is formed by coupling together two unit modules establishes that conversion module as a new structure identifiable as a unitary cassette. We discern that Fukui uses the term “conversion module” to refer to component 10, and uses that same term, i.e., “conversion module” to refer to component 20. See, e.g., Ex. 1004, 6:33–35, 7:23–25. The components 10A and 10B that make-up conversion module 20 are characterized as each being a “unit module.” See, e.g., id. at 7:25–27. Thus, once unit modules 10A and 10B are coupled together to form the structure that is “conversion module 20,” the current record reasonably suggests that the conversion module 20 is a component analogous to conversion module 10, but with a larger width, i.e., two times the width. Further, Fukui also characterizes unit modules 10A and 10B as being “fixed” to one another via coupling member 21 (see, e.g., id. at 10:11–16) and forming “one body” (see, e.g., id. at 8:2–3). Further still, as described and shown in Fukui (e.g., Figure 5), conversion module 20 is structured to operate via a singular multicore optical connector 16 from which optical fibers F1 extend to all of the single-core optical connectors 17 of the conversion module. Id. at 7:52– 8:6. Thus, conversion module 20 is recognizable has having a singular system of fiber optic components within its body. At this time, we regard such characterization of the coupled unit modules 10A and 10B as reasonably giving rise to an understanding that the resulting conversion module 20 constitutes a unitary module or cassette component.” slip op. at 20

See Prelim. Resp. 31–37. Patent Owner, however, states the following: “Patent Owner recognizes that this argument only reaches Sauter-based grounds, not Fukui-based grounds.

  • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied

    “In Fintiv, the Board explained that “cases addressing earlier trial dates as a basis for denial under NHK Spring have sought to balance considerations such as system efficiency, fairness, and patent quality.” Fintiv, Paper 11 at 5. Fintiv sets forth six non-exclusive factors for determining “whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” Id. at 6. These factors consider the following: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits.

    “outset, we note that the language of claims 1 and 12 is clear in reciting the presence of two distinct signals, i.e., a control signal and a reference signal, and that it is the control signal that “triggers” transmission of the reference signal. See Ex. 1001, 14:5–6, 60–62. Patent Owner credibly argues that the “two-step embodiment” of Figure 10 of the ’402 patent, and in particular steps 1005 and 1010, describe the control and reference signal transmissions that are encompassed by claims 1 and 12. See Prelim. Resp 8–10. Patent Owner also credibly argues that the Figure 10 embodiment is distinct from other disclosed embodiments, including the “single-step embodiment” of Figure 8. See id. at 10–11. Patent Owner further explains reasonably that the content of column 6 of the ’402 patent on which Petitioner relies has a more “natural reading” in distinguishing between separate transmission of a “control signal” that “triggers” separate transmission of a “reference signal” as described in connection with Figure 10 as juxtaposed with transmission of a “control channel,” which is distinct from a control signal, and a “reference signal” that may constitute a single transmission, as is described in conjunction with Figure 8. See id. at 16–17. It logically follows that if, as Patent Owner credibly argues, the claims of the ’402 patent do encompass the latter transmission scheme, rather than the former, then Petitioner’s reliance on Moon, as presented in its Petition, is insufficient to account for those claims. On this record, we need not decide whether Petitioner would likely prevail on the above-noted issues as Patent Owner raises sufficiently substantial arguments that the preliminary evidence, if unrebutted in trial, does not plainly lead to a conclusion that claim 1 is unpatentable by a preponderance of the evidence. Because, as noted above, Patent Owner has identified potentially dispositive gaps or flaws in Petitioner’s apprehension as to what is adequate in Moon’s disclosure to account for the claims of the ’402 patent, Petitioner’s proposed grounds cannot be said to rise to the level of a “compelling” meritorious challenge.” slip op. at 22

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.

Cir. 2023) (“Reasonable expectation of success refers to the likelihood of success in combining references to meet the limitations of the claimed invention.”). Patent Owner would require a successful outcome to be “quick and efficient wireless charging.” See PO Resp. 34–35. In making these arguments, Patent Owner is improperly superimposing the purported goals and purpose of Honda, the secondary reference, onto the ordinary artisan. See, e.g., id. at 41–45. However, the intended purpose of a prior art reference does not control the obviousness inquiry. Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021). Our reviewing court recently explained: The [motivation-to-combine] inquiry is not whether a relevant artisan would combine a first reference’s feature with a second reference’s feature to meet requirements of the first reference that are not requirements of the claims at issue. A contrary view would run counter to established principles, including that the claim defines the invention whose obviousness is being assessed and that a skilled artisan may be motivated to combine particular features of different references, e.g., to secure some benefits at the expense of others, even when bodily incorporation would be impossible or inadvisable. Axonics, Inc. v. Medtronic, Inc., 73 F.4th 950, 957 (Fed. Cir. 2023). Petitioner’s combination yields the benefit of the addition of wireless charging capability to a biosensor device. A person of ordinary skill in the art would find that benefit to be a motivating reason to make the combination. See, e.g., Ex. 1003 ¶ 176 (Dr. Duckworth’s motivation opinion based, in part, on “Kotanagi’s own statement that its rechargeable battery can be recharged ‘in a contactless state.’”); id. ¶ 149 (Dr. Duckworth describing a motivating factor in “Honda’s teaching of a wireless receive coil near a rear opening similar to that taught in Kotanagi (where both Honda’s and Kotanagi’s openings have a cover glass)” and opining that, in the proposed modifications, “the resulting magnetic flux would pass through the cover glass, as taught by Honda”); see also Ex. 1052, 45:16–46:2 (Dr. Anthony, on cross-examination and after being asked whether wireless charging is an improvement over wired charging for a consumer watch, responding that “in some instances it could be, and in others it may not be.”). And, as to a reasonable expectation of success, Patent Owner admits that “Petitioner has presented a device configuration in which a wireless charging coil could be provided in Kotanagi’s through hole 22.” PO Resp. 54; see also id. at 3 (Patent Owner arguing that “the size of coil that could be provided in this allegedly available space would be small and would significantly limit the amount of wireless power signal transmission,” but not arguing that even Patent Owner’s purported size-limited configuration would be inoperative); see, e.g., Ex. 1003 ¶¶ 155–156 (Dr. Duckworth credibly testifying that a person of ordinary skill in the art would have had a reasonable expectation of success in combining the teachings of Kotanagi and Honda).” slip op. at 27

    “would limit the size and positioning of a charging coil, and that the purported combination, as characterized by Patent Owner, would result in a “significantly degrad[ed] wireless charging efficiency” of Honda’s coil. PO Resp. 41–42; see id. at 36–45, id. at 55 (Patent Owner arguing that, “given the size restrictions imposed by Kotanagi,” the housing and cover glass cannot be expanded to allow for a larger coil). Patent Owner further argues that the combination would have to be configured a certain way and that the resulting configuration would “would frustrate Honda’s goals and intended purpose.” Id. at 37–38, 40–41; see also, e.g., id. at 43–44 (Patent Owner arguing that the combination, as characterized by Patent Owner, would inject noise and interference that are contrary to Honda’s goals of quick and efficient power transmission). We do not agree with this line of argument. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references.” In re Keller, 642 F.2d 413, 425 (CCPA 1981). The person of ordinary skill in the art is not compelled to blindly follow the teaching of one prior art reference over the other without the exercise of independent judgment. See Lear Siegler, Inc. v. Aeroquip Corp., 733 F.2d 881, 889 (Fed. Cir. 1984). As the Supreme Court recognized in KSR, “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton.” 550 U.S. at 421. Dr. Duckworth persuasively testifies that, “if, under the relevant engineering trade-offs, a POSITA wanted to increase charging speed, consistent with Honda’s teachings, Honda would have provided the motivation and information to either re-size or reshape Kotanagi’s protrusion and/or cover glass to provide for a larger coil.” Ex. 1060 ¶ 346; see also Ex. 1003 ¶¶ 157–159 (“[I]t would have been feasible to make the second modification option discussed above: to enlarge Kotanagi’s opening and cover glass to make room for a coil behind the cover glass, surrounding the LED and PD.”); Ex. 2039, 47:5–10 (“[A] POSITA would view Honda’s teachings to either modify Kotanagi to position wireless charging coil behind Kotanagi’s cover glass or enlarge the Kotanagi’s opening and cover glass to make room for a coil behind the cover glass.”); PO Resp. 44 (Patent Owner admitting that Honda teaches that metal is inferior for power transmission and “[t]his is precisely why Honda seeks to provide glass for its rear cover.”). And, although the references express certain goals, Patent Owner does not adequately identify any disclosure in either reference that disparages Petitioner’s articulated combination. See DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009) (“A reference does not teach away, however, if it merely expresses a general preference for an alternative invention but does not ‘criticize, discredit, or otherwise discourage’ investigation into the invention claimed.”). Even if, as Patent Owner argues, the proposed combination would not quickly charge the device, this is not dispositive. Dr. Anthony agrees that “[d]evices, depending on their use and their function, can benefit from either fast charge or trickle charge or a little bit of charge.” Ex. 1052, 19:3–6. “It’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.’” Intel Corp., 21 F.4th at 800 (quoting PAR Pharm., Inc. v. TWI Pharms., Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)); see also In re Mouttet, 686 F.3d 1322, 1334 (Fed. Cir. 2012) (“[J]ust because better alternatives exist in the prior art does not mean that an inferior combination is inapt for obviousness purposes.”); Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“[A] given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.”). Based upon the final record before us, we find that a person of ordinary skill in the art would consider even a slow charging configuration to be a suitable option.” slip op. at 29

    “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.

    “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.”).

    “Chae’s annotated Figure 6(b) “illustrates unlocking the second SIM (SIM2) according to the method for operating a mobile terminal.” Ex. 1005 ¶ 19. Ex. 1005, Fig. 6(b). Although Figure 6(b) “displays different items” (Ex. 1005 ¶ 109) such as the depictions of people (Lauran and Chris) and partly cloudy weather, Chae does not suggest that selecting these graphics causes display of an application. See PO Resp. 21. Petitioner contends that an ordinary artisan would have understood that selecting one of Chae’s graphics items must cause display of an application (see Pet. 55; Pet. Reply 11), but Chae does not teach or suggest this feature. As Dr. Cockburn persuasively testifies, “nothing in Chae indicates that the icons displayed in Figure 6(b) are dynamic or change in any way in response to content in the corresponding applications, and that the icons when selected causes display of the corresponding applications.” Ex. 2003 ¶ 46. The mere possibility that Chae’s generic graphical objects could perform a function is speculation because nothing in Chae teaches that selecting that graphical object would display a corresponding application. See id. The display of icons in Figure 6(b) does not inform the person of ordinary skill in the art whether the item has to indicate or contain content from an underlying application, and also whether it is selectable to get to that corresponding application as required by the claims. See Tr. 32:21–33:3. Petitioner’s reliance of the testimony of Dr. Rosenberg (see Ex. 1003 ¶ 91) is unpersuasive because Dr. Rosenberg merely restates the Petitioner’s assertions without reliance on persuasive evidence of record. See Xerox Corp. v. Bytemark, Inc., IPR2022-00624, at 5 (Feb 10, 2023) (Vidal, Dir.) (“[T]he Board was correct in giving little weight to Petitioner’s expert because the expert declaration merely offered conclusory assertions without underlying factual support and repeated, verbatim, Petitioner’s conclusory arguments.”). When addressing Chae’s three graphics in Figure 6(b) during cross-examination, Dr. Rosenberg testifies that “[t]hey’re not a numbered element, so they’re not spoken about specifically those three ones”). Ex. 2005, 56:9–14, 54:21–22 (“Chae doesn’t talk about the weather icon”). Further, the final record does not support Dr. Rosenberg’s testimony that a person of ordinary skill in the art would have understood that “part of the well-known functionality of widgets was that selecting a widget would cause ‘display of an application corresponding to the respective user interface object.’” Ex. 1003 ¶ 91. None of the references relied upon by Petitioner discloses this alleged “well-known functionality of widgets,” nor does the evidence of record support any industry standard usage of the term widget in the appropriate timeframe. See Ex. 2003 ¶¶ 46–48. Petitioner has also not persuasively shown that selections of Chae’s SIM card icons result in the display of an application as claimed. See Ex. 1005 ¶¶ 152–154, Fig. 22; see also Tr. 43:14–17 (“the claimed interface object causes display of the corresponding application, but selection of this paragraph 152, Figure 22 widget causes selection of something different, a sim environment.”). We find Patent Owner’s position more persuasive, when Chae uses the word widget, it is not using that word to refer to something that launches into an application, but instead Chae’s widgets show use-state information related to a SIM environment. See Ex. 1005 ¶¶ 152–154; Tr. 33:3–12. Specifically, Chae discloses “widgets that show use-state information of the first and second SIMs (SIM1 and SIM2),” and “when a user selects one of [the] widgets,” it “unlocks the SIM corresponding to the dragged widget.” Ex. 1005 ¶¶ 152, 153, Fig. 3 (unlocking SIM displays home screen customized to unlocked SIM). Chae does not support that these widgets relate to the graphic items in its Figure 6(b), nor does Chae explain how its widgets could be understood as the claimed “user interface objects” of the widget screen user interface. As explained persuasively by Dr. Cockburn, “the only widgets that are described in Chae are widgets relating to the use state of the multiple SIM cards,” and “[t]hese widgets described in Chae do not correspond to applications and thus do not cause display of applications when the widgets are selected.” Ex. 2003 ¶ 46 (quoting Ex. 1005 ¶ 152).” slip op. at 25
