      “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 does not demonstrate a reasonable likelihood that Petitioner would prevail in showing the unpatentability of at least one challenged claim 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).

      “area” in the challenged claims was added by amendment. 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. This is a snapshot of the tissue area as opposed to taking a time series of RF signals”), 191 (Examiner interview summary, stating: “Inventor noted that Uniyal uses a time series US [ultrasound] data whereas the invention uses images that are non-coherent in time (e.g., a static frame)”).” slip op. at 9

But Petitioner does not explain why Hope-Simpson’s “localized data sets” equate with a single frame of a tissue area rather than, for example, a time series of frames taken at the same location. Pet. 22. Petitioner cites the testimony of Dr. Papanicolau, but Dr. Papanicolau’s testimony lacks both technical reasoning and evidentiary support; it simply mirrors the statement in Petition.

      “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. Petitioner does not otherwise point to evidence that Patent Owner clearly and unmistakably limited the claim scope to rounded corners formed by a particular process.” slip op. at 12

      “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. Cir. 2021) (“If there’s a known technique to address a known problem using ‘prior art elements according to their established functions,’ then there is a motivation to combine.”). 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.

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.

      “Petitioner argues that limitation 1c is taught by the combination of Zhang with Fillebrown. Pet. 18.

Pet. 16–18 (citing Ex. 1004, 3:25– 60, 4:1–8, 4:32–50, 7:1–14, 8:13–22; Ex. 1003 ¶¶ 103, 104, 114–118).

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “We preliminarily disagree with Patent Owner. Although the claim lists step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Nothing in the express claim language precludes performing step 1d before step 1b, as in Zhang. For example, the claim does not contain temporal terms, like “then” or “next,” nor does the claim otherwise specify that step 1b must precede step 1d. Although Patent Owner points out that a term of step 1d (i.e., the one more available devices) derives antecedent basis from text in step 1b (i.e., one more available devices), this alone does not directly or implicitly require performing step 1b before step 1d. Prelim Resp. 6–7 (citing Ex. 1002, 240, ’648 patent prosecution history). Nor does the Specification require performing the step of identifying devices as available before the step of wirelessly signaling those devices or even that the steps be mutually exclusive. For example, there are no statements that this step order is important, nor disclaimer of any other order, nor any prosecution history indicating a surrender of any other order. Moreover, according to the Specification, announcer 30, which is the component that identifies devices as available prior to the wirelessly signaling, is only “preferably provided.” Ex. 1001, 7:28–31. Even assuming Patent Owner were correct that step 1b must precede step 1d, Patent Owner’s position that device(s) must be identified as available does not appear to be commensurate with the claims. According to its plain meaning, limitation 1b does not appear to require identifying devices as available; the claim merely requires identifying “available devices.” See In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (rejecting arguments “not based on limitations appearing in the claims”). In other words, the claim does not appear to require identifying (i.e., determining) whether devices are available but merely requires identifying devices that happen to be available. According to our preliminary understanding, Zhang’s mobile device 1) discovers (identifies) connected available and unavailable helper servers, and then 2) sends (wirelessly signals) service requests to compatible available and unavailable helper servers. Ex. 1004, 3:44–4:8, 6:51–7:13. Thus, Zhang identifies and then wirelessly signals available devices (Zhang also identifies and then wirelessly signals unavailable devices). As such, we preliminary determine that Zhang meets the claim language “identifying one or more available devices” and “wirelessly signaling the one or more available devices.”” slip op. at 18

Patent Owner’s definition of a person of ordinary skill in the art is similar to Petitioner’s definition with some variation in the amount of education and specificity as to the experience required. As Petitioner’s description of a person of ordinary skill appears commensurate with the subject matter before us, we apply Petitioner’s definition for purposes of this Decision.

Patent Owner also does not propose construction of any claim term. See generally, Prelim. Resp. Based on the record before us, we see no need for express construction of any term for the purposes of this Decision. Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “feature of scanning a wireless communication network by the mobile device receiving the streaming data for re-routing, to identify devices connected to the wireless network, are identified as capable to handle the routed media content.” Prelim. Resp. 5–6 (emphasis added) (citing Ex. 1002, 237–238). Thus, we understand the recited language to require scanning to find devices that have been identified as compatible, not just scanning to find devices and later determining which of those devices, if any, are compatible. Zhang, on the other hand, scans to find devices in the network, but that scan does not seek out devices identified as compatible. Specifically, Zhang scans to find its “helper environment” which is composed of “devices around them.” Ex. 1004, code (57); see also id. 2:16–20. The first step of Zhang’s process is to find “a local device [that] offers helper service.” Id. at 3:62–63. In the next step, Zhang then interrogates the device it scanned for in order to find out whether that device offers the necessary service. Id. at 3:63–4:5. In other words, Zhang is not scanning for compatible devices, but rather it is scanning for any device around it and then asking whether the device provides the necessary service. We find this to be insufficient because the claim is not merely seeking to identify a compatible device, but rather it is scanning “to identify a plurality of devices, identified as compatible to handle said media content.” Thus, for these claims it is not enough that the network be scanned for devices; instead, the network must be scanned for devices “identified as compatible.” The inclusion of Rofheart does not address this issue. Rofheart is relied upon to teach “that a local device identifies and connects with a plurality of remote devices.” Pet. 29. According to Petitioner, one of ordinary skill in the art would have used Rofheart’s teaching to improve Zhang by adding “the benefit of providing users control to select one or more of a plurality of devices, rather than always connecting to the first identified available compatible device, as taught by Zhang.” Id. As such, neither of the cited references addresses the recited scanning for devices identified as compatible.” slip op. at 21
