“parties on the present record, we are persuaded Petitioner sufficiently shows the combination of Bosnyak-392 and Son teaches or suggests all of the limitations of claim 1, and sufficiently explains how a person of ordinary skill in the art would have used Bosnyak-392’s teaching of using exfoliated, open-ended carbon nanotube fibers having two different aspect ratios in a composition with improved electrical and mechanical properties, with Son’s implementation of a specific bimodal distribution of aspect ratios, to arrive at the composition of claim 1 with a reasonable expectation of success. We do not find persuasive Patent Owner’s arguments that Bosnyak- 392 teaches away from using nanotubes with a lower aspect ratio, or that Bosnyak-392 has an objective of maintaining longer nanotubes.

“Thus, although both parties indicate that no claim construction is necessary at this stage of the proceeding, it is apparent that they disagree as to the meaning of “discrete carbon nanotubes.” While Petitioner appears to construe “discrete carbon nanotubes” as “nanotubes that are generally individually distinct” (Pet. 13), Patent Owner argues a more restricted construction requiring that “discrete carbon nanotubes” not be reacted with other components. Prelim. Resp. 3. The evidence relating to claim 10 In quotations from the Preliminary Response throughout this Decision, we have retained bolding and underlining added to the text by Patent Owner. construction that Patent Owner offers on the current record, however, does not address its proposed restriction. See id. at 9, n. 4, citing Ex. 1001, 3:9, 5:39–40 (“The ’649 Patent describes the ‘discrete carbon nanotubes’ as, for example, ‘individually dispersed’, ‘individualized carbon nanotubes’, ‘dispersed as individual nanotubes’, and ‘essentially discrete individual fibers, not entangled as a mass.’”). 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. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

If either party intends to argue a claim construction at trial, however, including what is the ordinary meaning of a term, they should do so in a clearly designated section of their briefing. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 21, 2019) (“CTPG”), 46, 49 (available at https://www.uspto.gov/TrialPracticeGuideConsolidated); O2 Micro Int’l Ltd. v.

“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

“To the extent Patent Owner is presenting a teaching away argument, these statements do not rise to the level of criticizing, discrediting, or discouraging investigation into the claimed invention. DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009). 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

“limitations that require specific connections between MIMO transceivers and arrays and a relationship between MIMO transceivers and beams.” Pet. 41. Petitioner contends that “Trigui teaches that each of the two modems (MIMO transceiver) would be connected to one of the two beams from each of the two arrays,” resulting in the interconnection requirements recited in the two “wherein” clauses of limitation [1b]. Id. at 41–42. Petitioner concludes that a person having ordinary skill in the art would have found the interconnection recitations of limitation [1b] obvious. Id. at 48–50; see id. at 48 (providing an annotated version of Trigui’s Figure 10 (modified to include two modems) and depicting the cross-connection of received signals). Petitioner contends that a person having ordinary skill in the art would have been motivated to cross-connect the MIMO transceivers and antenna arrays. Pet. 43; see id. at 42–43 (explaining direct and cross connection options); 44–48 (providing seven reasons why a person having ordinary skill example, Petitioner contends that a direct connection approach “does not take full advantage” of sharing antenna arrays. Id. at 44 (referencing Ex. 1004 ¶¶ 2, 62–63, 72, 79). As another example, Petitioner contends that cross-connecting minimizes the correlation of signals that reduces the capacity of a MIMO system. Id. (referencing Ex. 1006, 473–474; Ex. 1003 ¶¶ 239–240); see also Pet. 44–48 (providing other reasons).

Petitioner points out that Yeh “express disclos[es] that a ‘certain surrounding wall thickness is required’ ‘to stay within the burst, bending, and collapse ratings.” Id. at 42 (quoting Ex. 1005, 28:20–23; citing Ex. 1017, 24 (Equation (14) showing burst pressure roughly directly proportional to wall thickness), Ex. 1003 ¶ 295). Mr. Chambers provides support, explaining that Yeh “expressly taught that ‘to maintain the mechanical integrity (that is, to stay within the burst, bending, and collapse ratings) of the secondary flow paths, a certain surrounding wall thickness is required.’” Ex. 1003 ¶ 291 (quoting Ex. 1005, 28:20–24). According to Mr. Chambers, “a POSITA understood that containing internal pressure within tubing required a certain wall thickness, wall thickness being one of three parameters (wall thickness, tubing material, and tubing outside diameter) that could be adjusted to meet pressure containment requirements.” Id. “[A] POSITA would understand that the tubing wall thickness in the eccentric screens would be less than the tubing wall thickness in the concentric screens due to the lower pressure requirement.” Id. at ¶ 295.

“patent describes that “angular position transducer 78 is placed on top of swing leg pivot shaft 24” and that “pivot shaft 24 is rotationally fixed to the connector plate and duplicates the angular movements of swing leg 20 about the pivot shaft.” Ex. 1001, 12:15–16, 12:20–22, Figs. 5, 7. The ’723 patent also describes that “[a]ngular position transducer 78 is mounted inside . . . protective can 90 . . . which is bolted to hinge bracket 28 via an upright holding arm 92” and that “trigger pin 94 projects upwardly from the top surface of pivot shaft 24 and cooperates with angular position transducer 78 to generate an angular position signal.” Id. at 12:28–33, Fig. 5. These descriptions expressly convey that angular position transducer 78 is on pivot shaft 24 and mounted inside protective can 90 that is bolted to hinge bracket 28. Id. at 12:15–16, 12:20–22, 12:28–30, Figs. 5, 7; see also Prelim. Resp. 17 (describing the same embodiment shown in Figs. 5 and 7). According to Petitioner, the ’723 patent describes the pivot shaft as part of the hinge bracket, not the modular frame or swing leg. Pet. 109–110 (citing Ex. 1001, 7:42–46, 12:17–22). On the preliminary record, we agree because the cited portions of the Specification describe that a “hinge bracket is interposed between each swing leg and an associated surface of the bolsters and includes a fixed, upright pivot shaft that pivotally engages the swing leg for pivotal movements” and “pivot shaft 24 is rotationally fixed to the connector plate.” Ex. 1001, 7:42–45, 12:20–21. We also agree that “even if one were to find that the hinge bracket is part of either the modular frame or swing leg (contrary to the claims and specification treating these all as separate components), the specification would only provide written description for one of the claimed alternatives.” Pet. 110 (citing Ex. 1002 ¶ 199).” slip op. at 19

“Advanced Bionics stated that: If, after review of factors (a), (b), and (d), it is determined that the same or substantially the same art or arguments previously were presented to the Office, then factors (c), (e), and (f) relate to whether the petitioner has demonstrated a material error by the Office. Factor (c) focuses on the record developed by the Office in previously reviewing the art or arguments. It informs, therefore, the petitioner’s showing under factors (e) and (f), which focus on the petitioner’s evidence of previous Office error regardless of the context in which the same or substantially the same art or arguments were previously presented. For example, if the record of the Office’s previous consideration of the art is not well developed or silent, then a petitioner may show the Office erred by overlooking something persuasive under factors (e) and (f). On the other hand, if the alleged error is a disagreement with a specific finding of record by the Office, then ordinarily the petitioner’s required showing of material error must overcome persuasively that specific finding of record. That is, although Becton, Dickinson factor (c) evaluates “the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection,” the focus should be on the record when determining whether the Office erred in evaluating such art or arguments.” slip op. at 10

“track” that “is configured to rotate . . . relative to the jacking column,” Petitioner proposes modifying CIII in view of Rio “by positioning Rio’s rotary actuator 44 between the jacking column and crawler track, and using that rotary actuator to rotate CIII’s crawler track relative to the entire jacking column, rather than just its outer cylinder.” Pet. 45 (citing Ex. 1002 ¶ 89) (emphasis added); see also id. at 47 (citing Ex. 1002 ¶ 92; Ex. 1006, 5:8–11, 6:2–6). Petitioner argues such a modification would have been a design choice, one of a finite number of alternatives, obvious to try, and a known design that provides maneuverability. Id. at 29–31 (citing Ex. 1002 ¶¶ 61–67; Ex. 1006, 5:8–11; Ex. 1007, 5:14–59, Figs. 4–5; Ex. 1008, 7:35– 53, Figs. 7, 20; Ex. 1009 ¶¶ 5, 19–20, Fig. 2; Ex. 1011, 4:7–16, Fig. 3; Ex. 1013 ¶¶ 41, 44–45). At this stage, Petitioner’s arguments and cited evidence sufficiently support for institution that the modification would have been made so that the proposed combination would have had “a crawler track” that “is configured to rotate . . . relative to the jacking column.” Regarding claim 1’s “slew drive,” as discussed above, Petitioner proposes modifying CIII so that rotary actuator 44, the asserted slew drive, would be between the jacking column and crawler track. See Pet. 29–31. Petitioner also argues that, in the proposed combination, “actuating the rotary actuator causes the crawler track to rotate relative to the entire jacking column.” Id. at 47 (citing Ex. 1002 ¶ 92). The present record supports Petitioner’s argument that Rio’s worm gear actuator would have been understood to disclose a slew drive with support from the ’318 patent itself, the opinion of its declarant, and deposition testimony of Patent Owner’s expert in related litigation. Id. at 46–47 (citing Ex. 1001, 11:40–61; Ex. 1002 ¶ 91; Ex. 1006, 4:61–5:3; Ex. 1032, 84:12–86:17).
