“We conclude that interpretation of the term “wearable” is necessary to resolve the parties’ dispute. Patent Owner argues that the ’443 patent describes wearability of local audio devices and requires the local audio device to include an audio input device, such as a microphone, that is worn by the performer and connects to the performer’s local audio device to capture the performer’s isolated audio track. Prelim. Resp. 24 (citing Ex. 1001, code (57), col. 7, l. 65‒col. 8, l. 4, col. 8, ll. 59‒62, col. 21, ll. 60‒61).

Id. at 25 (citing Ex. 2017). We agree with Patent Owner’s analysis to the extent it specifies that the audio device is “suitable to be worn,” but do not include “performer” in the interpretation, as claim 1 recites an audio device wearable by a “creator of said locally generated audio.” See Prelim.

“As we explained in our Institution Decision, we disagreed then, and still disagree, “that the second pressure must be detected after the first pressure is detected (or that the third pressure must be detected after the first pressure is detected) simply because the second pressure is greater than the first pressure (and the third pressure is greater than the second pressure).” Dec. 27. As we explained there, “[t]he claimed relative magnitudes of the first, second, and third pressures do not define any temporal relationships regarding the detection of the pressures.” Id. We agree with Petitioner that claim 1 recites quantitative relationships for the pressures, not temporal relationships. Reply 4. For example, claim 1 requires “the second pressure greater than the first pressure” but says nothing about when the second pressure must be greater than the first pressure. A key misconception undergirding Patent Owner’s argument is its statement that “a ‘first pressure’ must first exist before the invention can detect that the ‘second pressure’ is greater.” PO Resp. 27 (emphasis added). The claim does not require detecting that the second pressure is greater than the first pressure. Limitation [1c] simply says, “detect a second pressure on the first input device, the second pressure greater than the first pressure.” In other words, all the detection that this limitation requires is detecting a second pressure. The claim then observes that the second pressure is greater than the first pressure but does not require detecting this. Limitation [1e] similarly detects pressure but not the comparison: “detect a third pressure on the first input device, the third pressure greater than the second pressure.” Thus, it does not follow that “a ‘first pressure’ must first exist before the invention can detect that the ‘second pressure’ is greater.” See id.

As Patent Owner’s argument relies on a claim construction we have not adopted, Patent Owner fails to undermine Petitioner’s persuasive showing.7 To the extent, as we note above, that the claims may require a partial ordering (i.e., limitation [1a] preceding limitation [1b] and limitation [1c] preceding limitation [1d], see supra Section I.A.1.a), Petitioner has persuasively shown that Komata discloses such ordering. a.

“We disagree with Patent Owner’s argument that the ordinary and customary meaning of “magnetic field sensor” refers to a device that measures only external magnetic fields. There is nothing in the claim language to suggest such a limitation: the plain language simply refers to a “magnetic field sensor,” without regard to how the sensor works or where it senses magnetic fields from. Ex. 1001, 12:16. In fact, the claim does not explicitly require sensing anything at all using the magnetic field sensor, merely reciting a “foreign object debris detection system” comprising the sensor and that the “foreign object debris detection system is configured to verify” the presence of FOD. The very general nature of how the magnetic field sensor is recited, without any explicit recitation of how its output may be used, undermines Patent Owner’s overly restrictive interpretation. Although the ’184 patent specification includes examples of measuring external magnetic fields to detect FOD, Patent Owner has not pointed to anything in the specification indicating an intent to restrict the term “magnetic field sensor” to only those sensors that measure external magnetic fields. Nor is there intrinsic evidence that an “eddy-current sensor” would not also be a magnetic field sensor, given that it senses magnetic fields. Indeed, as Petitioner persuasively argues, an eddy-current sensor still measures external magnetic fields—albeit magnetic fields generated within FOD through interaction with a powered sensor.

“Petitioner asserts that a person of ordinary skill in the art (“POSITA”), “at the filing date of the ’409 [p]atent[,] would have a master’s degree in electrical engineering, and at least two years of relevant work experience in the field of integrated circuit design and manufacturing.” Pet. 13 (citing Ex. 1003 ¶ 52). Patent Owner does not dispute Petitioner’s proffered level of ordinary skill in the art. PO Resp. 9 (citing Ex. 2021 ¶ 55). We adopt Petitioner’s proffered level of ordinary skill in the art, which is supported by unopposed declaration testimony and consistent with the ’409 patent and prior art of record. See, e.g., Ex. 1001, 1:6–3:8 (describing the invention and related art in terms of integrated circuit design and fabrication). Neither party, moreover, indicates the overall result would change based on a different definition.” slip op. at 10

“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.
