- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted
“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

“3. Analysis At this stage of the proceeding, we determine that Patent Owner’s statements made during prosecution of the ’195 patent appear to contradict its arguments in the present proceeding. See generally Prelim. Resp. Based on the present record, Patent Owner’s statements during prosecution support Petitioner’s argument tthat a graded dopant concentration is enough to teach aiding carrier movement in a particular direction. Patent Owner does not dispute that Kawagoe has a graded dopant concentration in the active region at this stage of the proceeding. Id. Patent Owner also does not dispute that Kawagoe’s transistor has carriers in the active region or that the graded dopant concentration of Kawagoe is lowered from the surface to the bottom substrate (Ex. 1007, Fig. 17). Id. At this stage of the proceeding, the evidence of record supports Petitioner’s position sufficiently to meet the reasonable likelihood threshold for institution. We decline to make further determinations, on this preliminary record, regarding the dispute surrounding this limitation, because the trial in the 00001IPR is the better proceeding in which to do so. Specifically, as compared to the preliminary phase of this case, the instituted trial in the 10 The examined claims of the ’195 patent generally recited “a unidirectional drift field drawing all minority carriers from said surface layer to said substrate.” Ex. 1016, 286.

“Pursuant to 35 U.S.C. § 314(a), the Director may not authorize an inter partes review unless the information in the petition and any preliminary response “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” See 37 C.F.R. § 42.4(a) (2024) (“The Board institutes the trial on behalf of the Director.”).

Lack of professional experience can be substituted by additional education, and vice versa. Pet. 12 (citing Ex. 1002 ¶¶ 62–63). Patent Owner does not dispute this assertion or present its own contention regarding the level of ordinary skill in the art. Based on the record presented, including our review of the ’394 patent and the types of problems and solutions described in the ’394 patent and cited prior art, we agree with Petitioner’s proposed definition of the level of ordinary skill for purposes of this Decision.” slip op. at 12

“C. Claim Construction We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner asserts that no claim requires express construction for the grounds presented in the Petition. Pet. 12. Patent Owner states that it applies the ordinary and customary meaning to the ’394 patent’s claim terms but does not propose any express interpretations. Prelim. Resp. 4. In view of these positions, we find that no express interpretation of any claim term is necessary to determine whether to institute an inter partes review in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted and emphasis added)).” slip op. at 13

“Based on the current record, we are persuaded that a POSITA would have been motivated to combine Weyman and Li as proposed by Petitioner. Pet. 21–25; Ex. 1002 ¶¶ 84–103; Ex. 1005 ¶¶ 4–5, 76, 98, 104–105, 119, 137–139, 162; Ex. 1007, 5:5–23, 1:17–19, 33:16–35:23. Patent Owner does not dispute that a POSITA would have been motivated to combine Weyman with Li’s channel joining processing unit. Furthermore, both references relate to similar subject matter, processing multicast stream requests, and Li’s channel joining processing unit addresses the problem of potentially overloading a port when doing so. See, e.g., Ex. 1005 ¶¶ 4–5 (“[A] primary object of the present invention is to provide a switching fabric, and units . . . [to] provide distributed multicast routing . . . . [and] to minimi[z]e the usage of bandwidth on links between the units of such a fabric.”); Ex. 1007, 1:17– 19 (“The present invention relates to the field of data communication, and, in particular, to a method, system, and access device for processing multicast service.”), 5:5–23 (“the maximum number of multicast channels that can be selected of a service port needs to be controlled”); see Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023) (“That [two prior art references] address the same problem and that [one of the references] was a known way to address that problem is precisely the reason that there’s a motivation to combine under KSR and our precedent.”). As pointed out by Petitioner, there is no apparent reason why these two concepts could not be combined together in a straightforward manner at the port level, so a POSITA would have had a reasonable expectation of success in doing so. Pet. 21; Ex. 1002 ¶¶ 93–94; see Elekta Ltd. v. Zap Surgical Sys., Inc., 81 F.4th 1368, 1377 (Fed. Cir. 2023) (“Evidence of reasonable expectation of success, just like evidence of a motivation to combine, ‘may flow from the prior art references themselves, the knowledge of one of ordinary skill in the art, or in some cases, from the nature of the problem to be solved.’”) (quoting Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1125 (Fed. Cir. 2000)). Furthermore, we are also persuaded on this record that the same benefits would have existed and motivated a POSITA to combine Li’s channel joining processing unit with Weyman’s aggregated high-capacity ports. See Pet. 21; Ex. 1002 ¶¶ 93–94.” slip op. at 25

“If a petitioner believes that a claim term requires an express construction, the petitioner must include a statement identifying a proposed construction of the particular term and where the intrinsic and/or extrinsic evidence supports that meaning.” PTAB Consolidated Trial Practice Guide at 44 (Nov. 2019) (“CTPG”).3 “On the other hand, a petitioner may include a statement that the claim terms require no express construction.” Id. In the petition in the Samsung IPR, Samsung contended that “the Board does not need to construe any claim term for purposes of evaluating the prior art,” i.e., that “the claim terms require no express construction.” Samsung Pet. 15.

Bright Data Ltd., IPR2022-00861, Paper 18 at 5 (Vidal Aug. 23, 2022) (Director decision) (precedential) (“Code200”); see Expedia, IPR2022-00785, Paper 16 at 9. Here, Petitioner presents substantively identical challenges to claims 2, 6, and 9–16 in the ’449 patent based on the same prior art and the same unpatentability theories as Samsung presents in the Samsung IPR. Compare Pet. 16–71, with Samsung Pet. 15–68; see Mot. Resp. 1. And as discussed above, copying a previously instituted petition is “common in the joinder context” and “an accepted approach.” Expedia, IPR2022-00785, Paper 16 at 7–9; see supra § III.C.1. Further, any differences between the Petition and Samsung’s petition did not result from roadmapping to correct a deficiency in Samsung’s petition because the Board instituted review in the Samsung IPR.

RulingsInstitution decision- Parallel petitionsDecided for petitioner
“On the present record, we agree with Petitioner that the two petitions filed to challenge the claims of the ’222 patent will not substantially burden the Board or the parties. The petitions in IPR2024-00673 and IPR2024- 00674 challenge different claims, and those claims appear on the present record to have different claim scope, as Petitioner argues. Paper 3, 3–4 (arguing that claim 44, challenged in IPR2024-00674, recites “a ‘surface layer,’ a ‘single drift layer,’ and ‘at least one well region disposed in the single drift layer,’ which are not” recited in the claims challenged in IPR2024-00673); Ex. 1001, 4:39–8:39. In addition, there is little overlap between the prior art asserted in the two petitions, and what overlap there is—the use of Kawagoe in both petitions—is used in different prior-art combinations in each petition. Compare IPR2024-00673, Paper 4, 5 (asserting Kawagoe alone and in combination with Gupta or Silverbrook), with IPR2024-00674, Paper 4, 5 (asserting Kawagoe in combination with Sakai). Accordingly, we do not exercise our discretion to deny either of the petitions challenging the ’222 patent for being parallel petitions.” slip op. at 5

“instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 16– 37. However, 35 U.S.C. § 315(b) also provides that the one year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b). Since the Petition is accompanied by a timely request for joinder (Paper 2) to the instituted proceeding (IPR2023-01244), which we grant as further discussed below (see infra § V), Patent Owner’s argument that the Petition is time-barred under 35 U.S.C. § 315(b) is moot, regardless of whether Petitioner is in privity with time-barred entities.” slip op. at 5
