“In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

“II. STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c).

“For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field.

“petition is warranted given the number of claims at issue. See Trial Practice Guide 59 (identifying situations where “two petitions . . . may be needed”). Patent Owner has asserted 166 claims in the co-pending district court litigation, and Petitioner challenges 91 unique claims in these petitions. See Ranking Notice 2; Ranking Response 2. Also, the vast majority of the challenged claims are asserted in litigation. See Ranking Response 2; Ex. 2004, 3. As a result, we agree that this is the type of “rare” situation where multiple parallel petitions are necessary. Petitioner’s primary argument is that seven petitions were required because the common sections needed to be repeated in each petition, which left few words for arguments directed to new claims (given word count limits). See Ranking Notice 2–3. But this argument is premised on an assumption that these common sections “require[d] approximately 8,350 words” (id. at 3), and Petitioner has not persuasively shown that so many words were actually required for these sections. Petitioner includes no explanation or justification of the length of the sections, but instead, it simply assumes that the words used were required. Having reviewed the analysis in those sections, we do not agree. In other words, although we agree that the common sections needed to be repeated in each petition (and that this reduced the number of words available for other analysis), we are not persuaded that the common sections required approximately 8,350 words. A petitioner is certainly entitled to allocate its words as it sees fit, and we typically have no reason to evaluate those strategic decisions; however, we agree with Patent Owner (see Ranking Response 3) that Petitioner cannot justify a large number of petitions by claiming that it needed additional words for its analysis (given the Board’s word count limits) unless Petitioner’s analysis was concise. 10 A petitioner is not entitled to an unlimited number of petitions (see Trial Practice Guide 59–61); instead, we determine whether the circumstances justify additional petitions (see id. at 59–60). This approach conforms with the rationale behind imposing a word count limit on petitions. See id. at 39 (discussing the reasons for establishing word count limits and urging parties to present “concise, well-organized, easy-to-follow arguments supported by readily identifiable evidence of record.”). i.e., the analysis of claim 2, the summary of the ’754 patent and prior art, the articulation of the level of skill in the art and claim construction, and the other preliminary comments—and we are not persuaded that they are sufficiently concise to support Petitioner’s argument. Claim 2 is only fifteen lines long, and its technology is relatively simple, yet Petitioner’s analysis of this claim stretches for seventeen pages. See Pet. 24–41. Petitioner provides no general information about the technology and submits that no claims need to be construed (id. at 7), yet Petitioner provides a five-page summary of the ’754 patent and its prosecution history (see id. at 2–6). Also, Petitioner provides a twelve-page summary of Ahn and Chaudhri (see id. at 7–19), despite the fact that neither reference is particularly long. Indeed, as Patent Owner notes, Petitioner was able to remove nearly 1,000 words from these common sections in at least one of the petitions. See Ranking Response 3–4. Because Petitioner’s analysis in the common sections does not appear to be concise, we are not persuaded that Petitioner’s use of approximately 8,350 words in those sections justifies the large number of petitions.” slip op. at 11

As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision.

“Contrary to Patent Owner’s arguments, the law on overlapping ranges in obviousness challenges is clear. See In re Peterson, 315 F.3d 1325, 1329 (Fed. Cir. 2003) (“A prima facie case of obviousness typically exists when the ranges of a claimed composition overlap the ranges disclosed in the prior art.”). Here, Petitioner directs us to evidence of an overlapping range, which is not meaningfully disputed by Patent Owner. As to Patent Owner’s arguments regarding the lower end of the claimed range of aspect ratios and Ohata’s warning about aspect ratios below 100, we note that Ohata states that its carbon nanotubes “preferably have an aspect ratio . . . of not less than 100,” and expressly includes examples with an aspect ratio of 50. Ex. 1004 ¶ 20 (emphasis added), Table 2 (Examples 12 and 14). Patent Owner also criticizes Petitioner for relying on oxidizing Ohata’s nanotubes in view of Kavan (discussed in more detail below). Prelim. Resp. 6. According to Patent Owner, oxidation is known to shorten the length of nanotubes, which would impact the aspect ratio of the nanotubes in the proposed combination. Prelim. Resp. 6. Specifically, Patent Owner contends that oxidizing Ohata’s nanotubes will reduce the aspect ratio below 100, and argues that “Petitioner has not explained why a [person of ordinary skill in the art] would ignore Ohata’s warning nor has Petitioner provided evidence that the resulting combination will perform as Petitioner alleges.” Prelim. Resp. 7; see also Prelim. Resp. 8 (arguing Petitioner has not explained why a person of ordinary skill in the art would try to retain Ohata’s aspect ratio and expect success when Ohata is altered in view of Kavan). Even giving Patent Owner’s arguments their full weight, there is no evidence on the present record as to how much the aspect ratio of Ohata’s nanotubes would be reduced as a result of oxidation. Rather, based on the present record, namely, the broad range of aspect ratios disclosed in Ohata (preferably 100–1000), it seems reasonably likely that the aspect ratio of at least some of the oxidized nanotubes in the proposed composition would remain within the range disclosed in Ohata and overlap the claimed range, as Petitioner asserts. Nevertheless, the parties may address during trial the expected level of carbon nanotube shortening in the proposed combination of Ohata and Kavan.” slip op. at 21

Indeed, in addition to its statement regarding oxidation not being necessary for anchoring to TiO2, Kavan also states that oxidation of carbon nanotubes “was sometimes mentioned to improve anchoring of TiO2.” Ex. 1005, 2. Moreover, the full statement from Kavan regarding storage capacity reads: “The Li-storage capacity of TiO2 is not enhanced in the composite, but the rate of electrochemical charge transfer is higher due to nanotube networking.” Ex. 1005, 9. Thus, in its entirety, this statement supports Petitioner’s argument that there are advantages to using oxidized nanotubes, and, in turn, provides a reason why a person of ordinary skill in the art would have used oxidized nanotubes. Moreover, the evidence Petitioner presents regarding the use of oxidized nanotubes in combination with TiO2, coupled with Ohata’s statement that the electrode active material to be used can vary depending on the battery type (Ex. 1004 ¶¶ 26–27), undermines Patent Owner’s criticism that Petitioner’s arguments are circular.” slip op. at 24

“Although the parties appear to agree that this factor is neutral, we note that a district court denial of a motion to stay without prejudice, accompanied by an indication that the district court would consider a renewed motion, “suggests the district court may be willing to avoid duplicative efforts and await the PTAB’s final resolution of the patentability issues raised in the petition before proceeding with the parallel litigation.” Fintiv at 6–7. “This fact has usually weighed against exercising authority to deny institution.” Id. (also noting that factors 2 and 3 are relevant to how much weight to give to the court’s willingness to reconsider a stay); see also T-Mobile, Paper 16 at 12 (noting that a stay was unlikely in that case given the proximity of the trial date to the entry of the institution decision). In view of the forgoing, we determine that Fintiv factor 1 weighs against exercising our authority to deny institution.” slip op. at 37

“On this record, we are preliminarily persuaded that Leaning teaches that each copy of the video is divided into sub-files that correspond to different temporal portions of the video. See, e.g., Ex. 1004, Abstr., 1:20– 28, 3:5–18, p.7 (table). We are also preliminarily persuaded Leaning teaches that each sub-file represents the same fixed time period (e.g., four seconds), and that each of Leaning’s sub-files has a corresponding sub-file in the other copies. See, e.g., Ex. 1004, Abstr., 6:21–7:2 (including table), 12:8–20. Moreover, we are preliminarily persuaded that Leaning’s sub-files each have a time index because the sub-file names are sequentially numbered. See, e.g., Ex. 1007, 7:1–2, 12:16–20, p. 7 (table); Ex. 1003 ¶¶ 71, 73.

To evaluate whether such a denial is appropriate, the Board determines: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of first part of the framework is satisfied, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims. Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH, IPR2019-01469, Paper 6 at 8 (PTAB Feb. 13, 2020) (precedential). In applying this two-part Advanced Bionics framework, we evaluate several non-exclusive factors, including: 13 Like the parties, we focus our analysis on Leaning. See Pet. 67–69; Prelim.

We are persuaded that Petitioner’s Leaning-only ground meets the standard for institution, and we do not reach Petitioner’s alternative ground based on Leaning and Gamble. See supra §§ II.E–F. Moreover, the statutory purpose of Section 325(d) would not be undermined by instituting on both challenges given Gamble’s limited role in Petitioner’s ground (see Pet. 58–60) and during prosecution (see, e.g., Ex. 1002, 208). art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which petitioner relies on the prior art or patent owner distinguishes the prior art; (e) whether petitioner has pointed out sufficiently how the examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the petition warrant reconsideration of the prior art or arguments.

Advanced Bionics, Paper 6 at 10. “If a condition in the first part of the framework is satisfied and the petitioner fails to make a showing of material error, the Director generally will exercise discretion not to institute inter partes review.” Id. at 8–9. “[T]his framework reflects a commitment to defer to previous Office evaluations of the evidence of record unless material error is shown.” Id. at 9.
