“We agree that Petitioner has not shown that a person having ordinary skill in the art at the critical time would have been motivated to replace the wordlines in the staircase region with dielectric material if the result is that one of the memory cell arrays becomes unavailable. Petitioner relies upon two usable arrays for its combination, emphasizing Thimmegowda as desirably enabling “a single conductive contact (e.g., 334a) to bidirectionally drive memory cells in the memory arrays on either side of the bridge”; i.e., both the left and right memory cell blocks.

However, such advantage is premised on retaining both arrays, and neither Petitioner nor Dr. Banerjee explains how the advantages of reducing punch-through should be weighed against a disadvantage of losing access to one of the two arrays. Nor do Petitioner and Dr. Banerjee discuss how the advantages of metal gate replacement should be weighed against losing access to one of the two arrays.4 Patent Owner’s declarant, Dr. Giapis, attests to the undesirability of such a combination, in which one array 4 Additionally, the claims of the ’604 patent do not require a metal conductor portion; Petitioner does not explain why gate replacement to a metal conductor from a polysilicon conductor, described as used in Lee’s “memory device at large,” (Pet. 40) is a benefit associated with Lee’s finger teaching relevant to the claims. Ex. 2007 ¶¶ 50–54.

“2. Conclusion Regarding the Merits The discussion above identifies weaknesses in the Petition that we have considered in our evaluation of Fintiv factors. While we do not make a determination regarding whether the Petition shows that there is a reasonable likelihood of prevailing were we to institute, for the reasons given, we determine that this Petition does not present particularly strong merits.

We take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv at 6. Because of the Sotera stipulation, factor 4 weighs strongly in favor of not exercising discretion. However, two other factors weigh in favor of exercising discretion, especially the trial date factor. The merits of Petitioner’s challenge are not particularly strong. A balanced assessment of the factors leads us to exercise discretion to deny the Petition.

“partes review “allays concerns about inefficiency and duplication of efforts,” and strongly weighs against exercising our authority to deny institution. Fintiv, Paper 11 at 6. Of the three district court proceedings, the Lenovo Group case, pending in the Eastern District of Texas, is the most significant to our analysis here. In the Lenovo Group case, Lenovo Group has not requested a stay. Prelim. Resp. 16. Patent Owner argues that the Lenovo Group case is not likely to be stayed based on that court’s low grant rate in other cases and the progress of that case in particular. Id. at 17. The district court in the HP case denied a stay without prejudice and stated that a stay could be reconsidered in the future depending on the outcome at the PTAB. Prelim. Reply 3. The Dell case has been stayed. Id. On this record, we decline to speculate as to how any of the involved district courts where no stay is pending might rule on any future motion to stay. Thus, we determine that, while one stay has been granted, the lack of a stay in the other underlying district court cases, especially the Lenovo Group case, is not sufficiently persuasive to weigh this factor against exercising discretion. Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 15 at 12 (PTAB May 13, 2020) (informative), cautions against speculating whether the district court would grant a stay if one were requested. Therefore, this factor has a neutral effect on the overall balancing of the Fintiv factors. B. Proximity of Trial Date to Projected Statutory Deadline (Factor 2) The scheduled trial date for the Lenovo Group case is November 3, 2025, which is about six months prior to the expected date for the final written decision here (i.e., late April 2026). See Prelim. Resp. 20; IPR2024- 01429, Ex. 2002 (Lenovo Group case Docket Control Order), 1. Petitioner argues this trial date is uncertain. Prelim. Reply 3. Further, Petitioner focuses its argument on what it terms a “growing backlog” in the Eastern District of Texas and “associated scheduling uncertainty.” Id. at 4. Petitioner refers to the status of the HP case, which is currently set for trial on September 21, 2026, and the stay in the Dell case. Id. Patent Owner responds that “[b]oth the scheduled trial date and the date of trial [in the Lenovo Group case] based on median time-to-trial statistics occur months before a final written decision would be expected here.” Prelim. Sur-reply 4. Patent Owner asserts that the time-to-trial statistics for the Eastern District of Texas project a median time-to-trial of 21.9 months. Prelim. Resp. 20–21 (citing Ex. 2007, U.S. District Courts Federal Court Management Statistics–Profiles—September 30, 2024). This projection yields a trial date that is prior to the expected final written decision date of April 2026. Prelim. Sur-reply 4. As with the previous factor, the status of the Lenovo Group case is our focus here. As stated, that trial is set to occur about six months before a final written decision would issue in this proceeding. The district court has stated that this trial date setting “cannot be changed without an acceptable showing of good cause.” Prelim. Resp. 20. We are not persuaded by Petitioner’s unsupported argument that the trial date is uncertain. We also consider the fact that the median time-to-trial statistic discussed by both parties projects a trial date earlier than the actual date set by the district court. Ex. 2007; Prelim. Sur-reply 1.

“E. Conclusion Regarding the Merits Petitioner does not present particularly strong merits. Petitioner’s arguments on the “bus limitation,” to succeed at trial, would require addressing a claim construction issue that was never addressed in the Petition and is arguably contradicted by the ’520 patent, which discloses transmitting packets representing a plurality of different control signals on a single bus. See Prelim. Sur-reply 2 (citing Ex. 1001, 7:34–38, 9:23–25, 9:50–54).

See Pet. 9–10. We determine this level of skill comports with the qualifications a person would have needed to understand and implement the teachings of the ʼ473 patent and the prior art of record.

“Petitioner’s representation of the problem as merely converting Petrauskaite’s disclosed mol% of triglycerides into wt% of triglycerides with simple calculations represents a form of prohibited reliance on hindsight. See Mintz v. Dietz & Watson, Inc., 679 F.3d 1372, 1377 (Fed. Cir. 2012) (hindsight to use the invention to define the problem the invention solves); see also Ecolochem, Inc. v. Southern Cal. Edison Co., 227 F.3d 1361, 1372 (Fed. Cir. 2000) (”Defining the problem in terms of its solution reveals improper hindsight in the selection of the prior art relevant to obviousness.”). “[W]hen someone is presented with the identical problem and told to make the patented invention, it often becomes virtually certain that the artisan will succeed in making the invention.” Mintz, 679 F.3d at 1377. Here, Petitioner urges that one of ordinary skill in the art need merely convert mol% of triglycerides in a specific fat blend into wt% of triglycerides in the specific fat blend. See Pet. 14–15 (“[T]he wt% of Petrauskaite’s fat blends can easily be calculated based on the generally available prior art knowledge of fatty acid compositions of palm stearin and soybean oil.”). Petitioner’s reasoning says no more than that a skilled artisan, once presented with Petrauskaite and prior art knowledge, “would have understood that they could be combined, but that is not enough.” PersonalWeb Techs., LLC, v. Apple, Inc., 848 F.3d 987, 993 (Fed. Cir. 2017) (that two references could be combined does not imply a motivation to pick out those two references and combine them to arrive at the claimed invention). Our reviewing court instructs that indicating that a skilled artisan could have made modifications to arrive at the claimed invention does not establish that a person of ordinary skill would have made such modifications. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“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.” (citing InTouch Technologies, Inc. v. VGO Communications, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014)). Petitioner attempts to check the “would have been motivated to modify Petrauskaite” box with testimony from its declarant, Dr. Maragoni. See Pet. 37–38. Such testimony includes [C]ombining such prior art elements according to known methods would have yielded nothing more than predictable results. A POSITA would naturally have turned to these references to understand Petrauskaite’s references better. Ex. 1003 ¶ 178. [T]he corresponding wt% of Petrauskaite’s fat blends] was readily-available and well-known in the art. Id. at ¶ 181. [T]he available information [on characterizations of oils and fats] is voluminous. Id. at ¶ 182. See Pet. 38. We find that such testimony fails to explain why the skilled artisan would have been motivated, without hindsight, to take the steps to reproduce the claimed invention, and to be conclusory, at best. On this record, we detect the taint of impermissible hindsight bias in” slip op. at 14

“Based on the preliminary record, we can reasonably expect trial in the parallel district court proceedings to begin four to five months prior to the deadline for our final written decision, based on the scheduled trial date and the median time-to-trial statistics. See Fintiv Memo 8–9 & n.12 (approving the use of median time-to-trial statistics). Even if the proceedings are staggered, at least one of the proceedings would likely begin and conclude well before our decision, making it highly likely that there will be duplicate efforts in evaluating the challenged claims based on the prior art.
