“Such an approach is inconsistent with the Supreme Court’s statements that in an inter partes review, “the petitioner is master of its complaint,” and “the petition [is] the centerpiece of the proceeding.” SAS Inst., Inc. v. Iancu, 584 U.S. 357, 363, 369 (2020). “It is of the utmost importance that petitioners in IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed. Cir. 2016) (quoting 35 U.S.C. § 312(a)(3)). In contravention of these principles, Petitioner’s approach improperly shifts the onus to Patent Owner or the Board to identify and parse out erroneous, and purportedly non-essential, citations to Saxonov and piece together an argument based on the remaining citations. As we stated in the Decision, we decline to assume this task. See Dec. 20. Finally, in the Request, Petitioner attempts to “show[] how Ground 6 is fully supported by undisputed prior art material.” Req. 6. This attempt is improper. Petitioner cannot use the Request as a means to supplement the Petition to identify purportedly essential citations and disavow erroneous or non-essential citations.” slip op. at 6

“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.

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.

“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.

“Accordingly, we find that on the current record Petitioner has not shown that it has a reasonable likelihood that it would prevail on these obviousness grounds. XII. DISCRETIONARY DENIAL – 35 U.S.C. § 325(d) In view of our determination that the Petitioner does not meet the threshold for instituting review on the merits, we need not address the parties’ dispute about whether the Board should exercise its discretion to deny institution under 35 U.S.C. § 325(d). Pet. 74–75; Prelim. Resp. 38–54; Pet. Reply 1–5; PO Sur-Reply 1–5. XIII. CONCLUSION After reviewing the information presented in the Petition and the Preliminary Response, we determine that, based on the evidence of record, Petitioner has not established a reasonable likelihood that claims 1–10 of the ’841 patent are unpatentable. XIV. ORDER Accordingly, it is ORDERED that, pursuant to 35 U.S.C. § 314(a), institution of an inter partes review of all challenged claims on all grounds presented in the Petition is denied.” slip op. at 35

“However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent. Therefore, the evidence of record does not show that the S2 generation of potato lines in Jong necessarily satisfies the homozygosity recitation in claim 1 of the ’841 patent, and so cannot establish on the record before us that Jong inherently teaches this limitation.” slip op. at 15

“Owner is telling. Petitioner does not refute Patent Owner’s evidence of objective indicia. On the current record, the objective indicia evidence is compelling. As to long felt need, Patent Owner cited evidence on record before the Examiner that showed a persistent need recognized by ordinarily skilled artisans. In re Gershon, 372 F.2d 535, 538 (CCPA 1967). For example, Dr. Huang states “This research is the breakthrough we have been waiting for since nearly a century . . . This is crucial for the potato breeding worldwide.” Ex. 2009, 687. There is no evidence that this long-felt need was satisfied by another before Appellant’s invention. See Newell Companies, Inc. v. Kenney Mfg. Co., 864 F.2d 757, 768 (Fed. Cir. 1988) (“[O]nce another supplied the key element, there was no long-felt need or, indeed, a problem to be solved . . . .”). Lastly, Dr. Lindhout explains that this invention satisfies the long-felt need, stating “I have discovered, and disclosed in the present application for patent, how a fertile homozygote in” slip op. at 33

The Board denied Cargill’s rehearing request, leaving institution denied for claims 1, 6–9, and 11–24 because the petition did not show a reason to combine the selected prior-art data without hindsight.

“Upon request for rehearing, we assess a decision on institution “for an abuse of discretion” (37 C.F.R. § 42.71(c) (2020)), which occurs when a “decision was based on an erroneous conclusion of law,” “clearly erroneous factual findings,” or “a clear error of judgment.” PPG Indus. Inc. v. Celanese Polymer Specialties Co., 840 F.2d 1565, 1567 (Fed. Cir. 1988) (citations omitted). The burden of showing a decision should be modified lies with the party challenging the decision. 37 C.F.R. § 42.71(c) (2020). The request 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. Thus, a request for rehearing is not an opportunity merely to disagree with the Board’s assessment of the arguments or weighing of the evidence, or to present new arguments or evidence. We have reviewed Petitioner’s Rehearing Request and carefully considered all the arguments presented. For the following reasons, we are not persuaded that we misapprehended or overlooked any arguments or evidence.” slip op. at 2

“As discussed in the Decision, “obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (citing InTouch Technologies, Inc. v. VGO Communications, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014)). No matter the result of combining the allegedly “readily available and well-known” information taken from particular examples from the “documentary evidence” with Petrauskaite’s disclosure, a POSITA had to have been motivated to do so at the time the invention was made.1 What is missing from the Petition is the “why.” The only motivating force in this case appears to be hindsight spurring Petitioner on to choose particular examples of palm stearin disclosed in Deffense and the soybean oil in Neff in order to justify its assertion that Petrauskaite discloses the claimed wt% ranges of triglyceride classes.” slip op. at 4

“Petitioner’s. We find no instance in the Petition in which “motivation” and “iodine value” are discussed together or linked in any way. The same can be said of Dr. Marangoni’s declaration. And, as noted in the Decision, it was not until the Preliminary Reply that Petitioner argued that specific data on fatty acid wt% used for the conversion calculations were selected to represent “knowledge generally available to one of ordinary skill in the art” due to similarity of the iodine value (“IV”) of the palm stearin (and soybean oil) disclosed in Petrauskaite. See Prelim. Reply 2–3. New evidence or argument in the Preliminary Reply that could have presented earlier is not permitted. On this record, we find Petitioner relies its Rehearing Request on arguments about a motivation to combine, stemming from the significance of iodine values, that were not raised in the Petition. Accordingly, Petitioner fails to support that the Decision misapprehended or overlooked arguments in the Petition about the significance of iodine values.” slip op. at 8
