      “inter partes review may not be instituted “unless . . . there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Under § 314, the Board may not institute review on fewer than all claims challenged in the petition.

If the Board institutes a review, it will institute “on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a). Upon consideration of the Petition, the Preliminary Response, and the evidence of record, for the reasons set forth below, we conclude the Petition demonstrates a reasonable likelihood that Petitioner would prevail in showing the unpatentability of at least one challenged claim in the ’294 patent. Accordingly, we institute an inter partes review of claims 1–20 of the ’294 patent.” slip op. at 2

      “II. ANALYSIS A. Level of Ordinary Skill in the Art Petitioner contends: A person of ordinary skill in the art at the time of the alleged invention of the ’294 Patent (“POSITA”) would have had a bachelor’s degree in Electrical Engineering, Computer Engineering, or in a similar discipline with at least two years of experience with wireless communication devices and networks. More education can substitute for practical experience and vice versa. Pet. 10 (citing Ex. 1004 ¶ 34). Patent Owner states that it “agrees with Petitioner on the level of ordinary skill in the art.” Prelim. Resp. 8 (citing Ex. 2001 ¶¶ 26–29).” slip op. at 9

      “Both parties rely on the language of claim 1 and the ’294 patent specification to support their respective constructions, and they emphasize that a user’s selective triggering of the control device does not issue different activation commands or control which data conveyance operation is used. Claim 1 recites an “invariable activation command” as a command that is “issued when said control device is selectively triggered by the user.” selectively trigger a control device “via one of a button, a keypad, a tactile screen, and a biometric parameter detector,” e.g., by entering a PIN that is authenticated, in order for an invariable activation command to be issued. Id. at 8:43–50, 10:26–29, 19:3–5. The claimed function of an invariable activation command is to “initiate[]” either a “first data conveyance operation” or a “second data conveyance operation” depending on whether “said switching element is in said first state” or “in said second state.” As explained above, the state of the switching element depends on whether or not an “activation cue” has been received by a “cue receiver.” The ’294 patent specification confirms the operation. Id. at 10:26–36, 15:14–28. The parties joust over the proper terminology for characterizing an “invariable” activation command, but they appear to agree on how the claimed cell phone and method work. The ’294 patent specification makes clear that the activation command is “invariable” in the sense that whenever a user selectively triggers the control device on the cell phone, for example by pressing a button on a keypad, the same command is issued to initiate a data conveyance operation regardless of the “state” of the “switching element” (i.e., in a “first state” or “second state”). The user cannot select or issue different activation commands. The selection of which of the two possible data conveyance operations will be initiated by selectively triggering the control device depends not on the activation command—it is always the same—but on whether the switching element has received an activation cue (“first state”) or not (“second state”). The ’294 patent neatly summarizes that “[t]he same invariable activation command will thus be issued upon [the] control device being triggered, and it is the state of [the]” slip op. at 12

      “The ’294 patent claims and specification make clear that the switching element switches between a “first state” and a “second state” depending on whether or not an activation cue is received. Ex. 1001, 9:28–41, 14:53–59. The state of the switch, in turn, “allow[s] data to be conveyed according to alternate data conveyance operations.” Id. (emphasis added). Thus, the claim limitation is recited as a “data conveyance switching element,” not a “data switch,” because the switching element allows the device to switch between alternate operations for conveying data from the cellular phone to an external data exchange device. Id. Patent Owner’s proposed construction “conflicts with the express disclosure of the ’294 Patent.” See Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed. Cir. 2005) (en banc) (The “specification ‘is always highly relevant to the claim construction analysis. Usually, it is dispositive; it is the single best guide to the meaning of a disputed term.’”) (citation omitted). On the present record, we determine that no further construction of claim terms is necessary to determine whether to institute a trial in this case. See, e.g., Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (“[C]laim terms need only be construed ‘to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. &” slip op. at 16

The Petition is unclear as to which McGregor device is being referenced, e.g., the smart card of Figure 2, the wallet embodiment of Figure 4, or some combination of embodiments disclosed in McGregor and Palmer. Id. Regardless, the proposed modification of McGregor in view of Palmer, as we understand it, is based on conclusory reasoning and appears to be motivated by hindsight rather than the teachings of the applied references. Prelim. Resp. 38–40 (citing Ex. 2001 ¶¶ 97–102). 7 Ground 2 challenges independent claim 11 for asserted obviousness over McGregor, Palmer, and Tuttle. The Petition’s reliance on Tuttle for its teaching of distinct data transmitter, data receiver, and cue receiver ports does not alter our analysis for claim 11. Pet. 55–62. POSITA would have understood that a series of instructions would be programmed into McGregor’s microprocessor to function as a switching element (pursuant to Palmer’s teachings), and as described.in the ’333 Patent. See Claim [1(b)]; see ’333 Patent, 6:9-14. Accordingly, McGregor’s microprocessor is a switching element (1) that is placed into an activated state after receiving a handshake signal (an activation cue) that establishes a communication during the handshake process and (2) that remains in an inactivated state if no reader/writer device is detected (no activation cue). Ex. 1003 ¶ 127 (emphases added). Dr. Buehrer’s citation to the ’333 patent, without explaining his mapping of limitation [1(e)] onto McGregor-Palmer beyond a general reference to 10-plus pages of limitation [1(b)] “control device” analysis, suggests hindsight reasoning. Id; see also Pet. 42 (generally referring to limitation [1(b)]). The Petition’s analysis, moreover, does not address why or how McGregor’s microprocessor would “accordingly” act as a data conveyance switching element or why a POSITA would want to program McGregor’s microprocessor to execute such a switching function in view of Palmer. We find the Petition and Dr. Buehrer’s testimony lacking in articulated reasoning supported by rational underpinnings sufficient to support the conclusion that limitation [1(e)] reads on the proposed McGregor-Palmer combination.

Ex. 1004, 181.8 In making the amendment, Applicant stated that the language added by amendment was intended to distinguish the pending claims over Uniyal,9 which Applicant characterized as disclosing a “time series” of ultrasound data. Uniyal relies on a time series of ultrasound data. In order to distinguish Uniyal, the claims have been amended to recite a single static set of ultrasound RF data in a single frame of the tissue area. As explained in the Interview, the claims rely on a signle [sic, single] “snapshot” frame of the ultrasound RF data rather than a time series or [sic, of] RF data as disclosed in Uniyal. Applicant respectfully submits the amended claims are allowable over all of the cited reference. Id. at 186–187; see also id. at 185 (Applicant’s remarks accompanying amendment, stating: “As explained in the Interview, a static set of raw ultrasound RF signals is collected for an area.

      “Based on the arguments and evidence, we disagree with Petitioner’s proposed construction requiring the corners to be rounded via a particular process, because doing so would improperly import a process of manufacture from the Specification into apparatus claims. See Cont’l Circuits LLC v. Intel Corp., 915 F.3d 788, 799 (Fed. Cir. 2019) (explaining that, generally, a novel product that meets the criteria of patentability is not limited to the process by which it was made, however, process steps can be treated as part of a product claim if the patentee has made clear that the process steps are an essential part of the claimed invention). Here, the portions of the Specification relied on by Petitioner (Ex. 1001, 2:10–20, 4:53–64) disclose a process for manufacturing but do not make clear that the process is an essential part of the claimed invention. We also disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from Pfirsch’s rounded corners, which, presumably, are formed as an incidental result of lithography. On the contrary, the Examiner found (and Patent Owner acknowledged) that Pfirsch has rounded corners. Ex. 1002, 276, 295, 302. As Patent Owner correctly points out, the claims were amended during prosecution to include a “circular” contact to distinguish over Pfirsch’s square contact. See id.

      “is ‘known’ is not sufficient for a motivation to combine.” PO Resp. 47. However, the motivation-to-combine analysis is a flexible one, and the “known-technique” rationale is adequate to show a motivation to combine. For example, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417; see also Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380 (Fed. Cir. 2023) (quoting Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 799–800 (Fed.

Here, as discussed above, the record shows that top view rounding was a known technique to eliminate corners, and that corners were a known problem (e.g., corners tend to reach undesirable higher peak electric field leading to premature breakdown voltage). See, e.g., Ex. 1003 ¶¶ 37, 39, 42– 44, 55–57, 122, 133, 135–141; Ex. 1005, 7:57–8:4; Ex. 1006, 1:18–21, 2:19–39, 5:3–17, Figs. 6A–8B; Ex. 1011, 1:29–41; Ex. 1012; PO Resp. 13, 46 (citing Ex. 1011, 1:34–40); Ex. 2021 ¶ 87. Furthermore, there is no dispute that modifying Kobayashi to eliminate corners via top view rounding was anything more than a “minor and commonplace modification” of cell shape within the skill of an ordinary artisan, or that top view rounding would change Kobayashi’s established function.

      “We agree that Kobayashi’ s Figure 5A solely cannot be relied upon as disclosing the claimed diameter. See Hockerson-Halbertstadt, Inc. v. Avia Group Int'l, 222 F.3d 951, 956 (Fed. Cir. 2000) (patent drawings not designated as being drawn to scale cannot be relied upon to define precise proportions of elements if the specification is completely silent on the issue). However, we do not agree that Petitioner failed to show Kobayashi suggests the recited diameter. We disagree with Patent Owner’s assertion that Dr. Liu’s “vague, purported ‘design considerations’” are “unsupported.” PO Resp. 43. Although Kobayashi is silent on the width/diameter of the trench contact in Figure 5A, Kobayashi discloses trenched gates having dimensions below 0.5 μm, which demonstrates that it was known in the art, and required no more than an exercise of ordinary skill in the art, to create trenched features of widths well below 1 μm. Kobayashi also discloses that the width of each trench, and the distance between the adjacent trenches (which includes the trench contact), must be selected to optimum sizes . . . [and] these sizes . . . have some degrees of freedom.” Ex. 1005, 7:42–48. This demonstrates a POSITA would seek to optimize trench contact width or diameter. Dr. Liu’s testimony regarding design considerations suggests the desirability of a reduced diameter trench contact, e.g., to minimize the width of the trench contact for purposes of easier filling, to minimize the total width of the unit cell, and to minimize manufacturing time by reducing etch back time. See Ex. 1003 ¶¶ 111–114. As Patent Owner acknowledges, “there is always a motivation to speed up the fabrication process or shrink feature sizes of semiconductors.” PO Resp. 43 (citing 2021 ¶ 131). However, contrary to Patent Owner’s arguments, these are not generic motivations “untethered” from Kobayashi. Id. Indeed, Kobayashi directly addresses the fabrication process (including new techniques to obtain trench widths under 0.5 μm) and the need to optimize the size of trench gates and the space in between (which includes the trench contact). Ex. 1005, 7:43–54, 7:19–9:53. Patent Owner also argues that Petitioner presents no evidence that modifying Kobayashi to have a diameter smaller than 1 μm is predictable. PO Resp. 44. We disagree. As discussed above, Petitioner points to Kobayashi’s teachings that the sizes are to be optimized and that the trench gate width is smaller than 0.5 μm, which suggests making other trench features of that width was within ordinary skill. Ex. 1003 ¶ 112. Furthermore, Kobayashi’s silence as to the dimensions of the trench contact suggests that the trench contact diameter dimension is likely in the ballpark of the other explicitly disclosed trenched feature dimensions and is a matter of routine optimization. In addition, Patent Owner advances no persuasive evidence that the claimed diameter produces unexpected results or is otherwise critical. Patent Owner also argues that reducing trench contact diameter has downsides (i.e., reduced ease of filling for metal plugs and reduced current carrying capacity) not addressed by Petitioner; however, Petitioner is not required to address those tradeoffs in its Petition, and we do not see how those tradeoffs would prevent the proposed combination. PO Resp. 44; see 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.”); Winner Int'l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.”). Here, Dr. Liu listed numerous benefits of having a reduced diameter, which weigh against the potential downsides raised by Patent Owner. Ex. 1003 ¶¶ 111–114. Moreover, we do not see how the downsides/tradeoffs prevent modifying Kobayashi in the manner suggested when the same tradeoffs appear to be applicable to the ’409 patent.

      “Alternatively, even if we set aside that timing issue, Dr. Liu’s bare opinion, advanced for the first time during cross-examination, that an epitaxial layer is “obvious” from Hirler’s disclosure is inadequate to support the challenges. Id. at 24–25. We accord little weight to Dr. Liu’s opinion because it is conclusory. See Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In any event, Petitioner does not meet, on this record, the “high standard” required to establish an inherent disclosure of an epitaxial layer in Hirler. PO Resp. 24.6 Dr. Liu opined for the first time during cross-examination “that it would have been impossible to create Hirler’s more lightly doped n- drift zone layer on top of its more heavily doped n+ substrate layer other than via epitaxy.” Id. at 25 (citing Ex. 2014, 164:16– 165:20). But Patent Owner effectively refutes that proposition with evidence that such a layer “could be created by counter-doping,” even if, as Dr. Liu contends, counter-doping may have been less ideal due to “disadvantageous mobility.” Id.

      “Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Resp. 4). In determining at this stage of the proceeding that Petitioner has demonstrated a reasonable likelihood of establishing unpatentability of at least one challenged claim (namely dependent claim 11 in this case), we need not and do not construe expressly any claim terms. Nevertheless, we encourage the parties to submit proposed constructions for the limitation “determining a UE [i.e., User Equipment] environment information,” as recited in dependent claim 11. See Ex. 1001, 49:12–15, 1:40–42 (emphasis added). To the extent that a party proposes that this limitation should have its ordinary and customary meaning, the party should submit and explicitly identify such meaning. O2 Micro Int’l Ltd. v.

For example, the parties should discuss (a) the meaning and scope of “determining” as used in the subject limitation; (b) the meaning and scope of “environment information” as used in the subject limitation; (c) any relationship or overlap between “environment information” and “link quality positioning information,” as recited in dependent claims 7 and 11 (see Ex. 1001, 48:62–65, 49:12–15); and (d) whether UE “environment information” includes location or orientation of the UE.” slip op. at 10

      “Petitioner contends the skilled artisan would have had rational reasons to combine the teachings of Jarvinen and Fox to arrive at the invention of dependent claim 11 (which includes the features of independent claim 1 and dependent claim 7) and would have had a reasonable expectation of success in doing so. Pet. 37–41; see, e.g., id. at 38 (“[The skilled artisan] faced with the problem of estimating a UE’s future link quality at a location would have looked to Fox because Fox solves the problem of estimating future link quality with the exact same information available to Jarvinen.”); Ex. 1012 ¶ 70 (Dr. McClellan testifying that “[a]ll of the data upon which Fox relies is already disclosed and linked together in Jarvinen’s database, and it would have been obvious for [the skilled artisan] to combine Fox’s method of looking up previous link quality to estimate future link quality with Jarvinen’s teachings.”); ¶ 72 (Dr. McClellan testifying that “modifying Jarvinen to perform Fox’s link quality estimation would have constituted a simple substitution of a known element to yield predictable results.”). Patent Owner does not dispute such reasons or expectations at this stage of the proceeding. For the reasons and evidence set forth in pages 37–41 of the Petition, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox to arrive at the invention of claim 11, and to do so with a reasonable expectation of success. c) Summary At this stage of the proceeding and based on the record before us, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox with a reasonable expectation of success, and sufficiently supports Petitioner’s contention that dependent claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox. Thus, for the foregoing reasons and those stated in Petitioner’s preliminary briefing (Pet. 17–47, 50–51, 54), we determine that Petitioner has established a reasonable likelihood that it would prevail in showing that claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox.” slip op. at 18
