    The Board denied institution of IPR challenging claims 2, 27–30, 32–36, 38, 40, 42–44, 46, 47, 52, 54, 57, and 59, exercising discretion because this was the fourth-ranked parallel petition.

      “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

      “We agree with Patent Owner that Petitioner fails to explain why the Leaning grounds in IPR2024-00940 are not sufficient for challenging claims 1–20 of the ’234 patent. Indeed, “both petitions contain strong invalidating prior art” by Petitioner’s own reckoning (Pet. Ranking 2), and Petitioner characterizes Leaning as “undoubtably very strong invalidating prior art” (id. at 4). We further note that both petitions challenge all 20 claims of the ’234 patent, so the scope of the challenges is exactly the same in both cases. As a result, we are not persuaded that the differences between the petitions militate in favor of instituting both proceedings.” slip op. at 10

      “Our intent in formulating the factors was to take undue inequities and prejudices to Patent Owner into account. Thus, factor 3 is directed to Petitioner’s potential benefit from receiving and having the opportunity to study Patent Owner’s Preliminary Response, as well as our institution decisions on the first-filed petitions, prior to its filing of follow-on petitions. As discussed in our Decisions Denying Institution, we are concerned here by the shifts in the prior art asserted and the related arguments in follow-on petitions. See Dec. 11. Multiple, staggered petitions challenging the same patent and same claims raise the potential for abuse. The absence of any restrictions on follow-on petitions would allow petitioners the opportunity to strategically stage their prior art and arguments in multiple petitions, using our decisions as a roadmap, until a ground is found that results in the grant of review.14 All other factors aside, this is unfair to patent 14 The Board has addressed efficiency and potential prejudice induced by multiple petitions in multiple cases.

Considering other factors (i.e., factors 2, 4, and 5) allows us to assess and weigh whether a petitioner should have or could have raised the new challenges earlier. We recognize that there may be circumstances where multiple petitions by the same petitioner against the same claims of a patent should be permitted, and that such a determination is dependent on the facts at issue in the case. The factors set forth above, in our view, represent a formulation of relevant considerations that permit the Board to assess the potential impacts on both the efficiency of the inter partes review process and the fundamental fairness of the process for all parties. We recognize, also, that additional factors may arise in other cases for consideration, where appropriate. However, the factors set forth above, at the very least, serve to act as a baseline of factors to be considered in our future evaluation of follow-on petitions.” slip op. at 17

      “panels to authorize, an expanded panel. See generally 35 U.S.C. § 6; 37 C.F.R. §§ 41.1–42.412; see also AOL Inc. v.

Our standard operating procedures, however, provide the Chief Judge with discretion to expand a panel to include more than three judges. PTAB SOP 1, 1–3 (§§ II, III) (Rev. 14); see id. at 1 (introductory language explaining that the Director has delegated to the Chief Judge the authority to designate panels under 35 U.S.C. § 6); see also In re Alappat, 33 F.3d 1526, 1532 (Fed. Cir. 1994) (providing that Congress “expressly granted the Commissioner the authority to designate expanded Board panels made up of more than three Board members.”). The Chief Judge may consider panel expansions upon a “suggestion” from a judge, panel, or party in a post-grant review. Id. at 3–4; see also Apple Inc. v. Rensselaer Polytechnic Inst., Case IPR2014-00319, slip op. at 2 n.1 (PTAB Dec. 12, 2014) (Paper 20) (expanded panel) (per curiam). The standard operating procedure exemplifies some of the reasons for which the Chief Judge may expand a panel. PTAB SOP 1, 3 (§ III.A). For example, an expanded panel may be appropriate when “[t]he proceeding or AIA Review involves an issue of exceptional importance.” Id. (§ III.A.1). In these cases, the Chief Judge has considered whether expansion is warranted, and has decided to expand the panel due to the exceptional nature of the issues presented.4 As we discuss further below, follow-on petitions have been at issue in multiple cases before the Board. The Chief Judge has determined that an expanded panel is warranted to provide a discussion of factors that are considered in the exercise of the Board’s discretion under 35 U.S.C. § 314(a) and 37 C.F.R. § 42.108(a).” slip op. at 4

      “These explanations, without more, do not justify permitting Petitioner to wait to file its Second Petition until after it has had the advantage of seeing our Decision on Institution in the First Petition. Contrary to Petitioner’s suggestion, the decision to file two separate petitions to challenge the claims asserted in the related ITC and the district court would not appear to conserve either the Board’s or the parties’ resources. Rather, it would appear to expend more resources than challenging all of the claims in one Petition. Indeed, it would appear Petitioner could have simultaneously challenged all of the claims asserted in the related ITC and district court proceedings, as the prior Petition demonstrates Petitioner knew of both the ITC and the district court actions when the prior Petition was filed. See Case IPR2016-01381, Paper 1, 1–2. Consequently, this factor also weighs against institution. Weighing the Factors for Discretionary Non-Institution Under § 314(a) We view Petitioner’s strategy in this particular case as burdensome to Patent Owner and the Board with no persuasive explanation of why it should be allowed. Petitioner does not even attempt to assert that it could not have raised the challenges in the Second Petition simultaneously with the challenges raised in the prior Petition. And we find Petitioner’s explanation of why it chose to delay filing the Second Petition unpersuasive. We do not take lightly denying a petition on grounds unrelated to its substantive patentability challenges. Nor do we hold that multiple petitions against the same claims of the same patent are never permitted. Here, however, we view the prejudice to Patent Owner to be greater than that to Petitioner. We, therefore, decline to institute inter partes review under 35 U.S.C. § 314(a).” slip op. at 12

See Ex. 1103, 41. Petitioner produces no evidence of any kind to support its belief that the Examiner misapprehended Suzuki. In the absence of such evidence, we are unwilling to assume that, after having uncovered a very limited amount of relevant art, the Examiner failed to consider at least that art, either alone or in combination, with respect to the filed claims.
