“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

“On this record, we preliminarily agree with Petitioner that the claim limitations amount to a combination of known elements that a POSITA could have combined to achieve predictable results. See Intel, 21 F.4th at 799–800 (determining that a showing of the obviousness in predictable use of prior art elements according to their established functions requires only a showing that the combination be a suitable option). Among other reasons, the preliminary record supports Petitioner’s arguments that combining the teachings of Blumenberg, Bhumkar, and Griffin amounts to applying known solutions in the field of computer interfaces with predictable outcomes. See Pet. 12–18. As noted above, we encourage the parties to address the scope and meaning of the “when” limitations as a matter of claim interpretation, but we do not currently understand the plain language of Limitation [1.o] to require that the “portion of the second web page” or “menu” is displayed only after expiration of the “second user-configurable predefined duration,” termed by Patent Owner the “Alternative Modification.” Again, we encourage the parties to fully address this issue as a matter of claim construction. We additionally note that, even if we were to interpret the claims to require that the recited functions of Limitation [1.o] occur only the “prerequisite elements” are satisfied, we are still preliminarily persuaded by Petitioner’s arguments that combined teachings of the prior art satisfy the claim elements as a mere combination of known elements combined according to their known functions with predictable results.” slip op. at 27

“scenarios. Pet. 1 (characterizing three claimed scenarios as (i) an “inadvertent” contact, (ii) a “tap” contact, and (iii) a “hold” contact), 4 (“Independent Claims 1 and 42 outline three scenarios regarding a user’s contact with a touch screen device”); Prelim. Resp. 3 (“With respect to claim 1, these three scenarios include: . . . .”); see Ex. 2001 ¶¶ 28 (“As recited in claim 1, the three different claimed functionalities are executed ‘when’ the prerequisite elements are met (described as three scenarios by Dr. Cockburn.”) (citing Ex. 1001, 102:50–103:55; Ex. 1003 ¶¶ 33–35), 29–32 (describing the first, second, and third scenarios). In substance, the parties’ dispute appears to concern whether the plain language of the claims requires that a recited function must be performed only after or in response to expiration of a threshold (and other prerequisites), as opposed to requiring a function that begins before and continues after expiration of a threshold. Notably, dependent claim 3 recites: “The electronic device of claim 1, wherein the electronic device is configured such that the first feedback that is perceptible by touch is output prior to the display of the menu.” Ex. 1001, 104:1–4 (emphasis added). Given that independent claim 1 is necessarily broad enough to include claim 3, it seems on this record that the functions recited in Limitation [1.o] necessarily can happen at different times, as opposed to, for example, only responses that are triggered by the so-called “prerequisite elements.” We encourage the parties to address this issue as a matter of claim interpretation in future briefing. Based on the current record, however, we determine that it is not necessary to provide an express interpretation of any claim terms at this stage of the proceeding. See Realtime Data, LLC v.

“Furthermore, we are not persuaded that modifying Aksu in view of Gonzalez in the manner proposed by Petitioner overcomes this problem. As noted above, Petitioner asserts that, in the proposed combination, one of ordinary skill in the art “would have understood that the Laplacian’s output would be compared directly to a threshold based on β—just like Aksu’s difference calculations—to determine how many pixels to filter.” Pet. 60 (citing Ex. 1019, 13:15–19; Ex. 1003 ¶¶ 406–410). We disagree with this assertion, however, because it relies on erroneously equating the output of calculations (i.e., |r1-rj| and |r1-ri+1|). In other words, Aksu’s difference calculations, although used in setting dr, are not the same as dr; and we are not persuaded that one of ordinary skill in the art would have considered comparing Gonzalez’s Laplacian output to threshold β because Aksu discloses comparing its difference calculations to β. As noted above, we are not directed to any disclosure in Aksu of comparing dr to β. In addition, Dr. Schonfeld’s testimony on this point is not persuasive. Specifically, Dr. Schonfeld testifies that “dr can simply be defined as the output of the Laplacian (dr=|r3-2r2+r1|), and dr could be directly compared to a threshold based on β.” Ex. 1003 ¶ 408 (underline emphasis added). This testimony, however, is entitled to little weight because Dr. Schonfeld fails to provide a sufficient underlying basis for his opinion. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Nobel Biocare Services AG v. Instradent USA, Inc., 903 F.3d 1365, 1382 (Fed. Cir. 2018) (explaining that the Board can reject arguments based on expert testimony that lacks specificity or detail). Moreover, opining that output of the Laplacian, dr, could be directly compared to β does not establish sufficiently that one of ordinary skill in the art would have been motivated to do so.

“U.S.C. § 314(a) due to the advanced state of the parallel district court action, and, in doing so, relies heavily on the district court’s scheduled trial date of September 22, 2025. See Prelim. Resp. 51, 54. While the district court’s scheduled trial date may be earlier than the Board’s projected deadline for a final written decision here, CamelBak’s reliance on that date is misplaced. The Office takes the position that a district court’s scheduled trial dates are “unreliable and often change” and that a more reliable indicator is the district court’s “median time-to-trial for civil actions,” which, in this case, would place the district court’s trial date after the projected deadline of any final written decision here. See Director Memorandum, Interim Procedure for Discretionary Denials in AIA-Post Grant Proceedings With Parallel District Court Litigation, U.S. PATENT AND TRADEMARK OFFICE (June 21, 2022) (“Director’s Interim Procedure”), at 8–9. Thus, CamelBak’s reliance 5 US D586,184 S, issued Feb. 10, 2009 (Ex. 1006, “Miller”). on the district court’s scheduled trial date has no bearing on whether we should discretionarily deny institution. Of greater relevance is Trove’s express stipulation not to pursue the same grounds in the district court action as advanced in the petition or any ground that relies on the prior art references cited in the petition. See Pet. 100. Although not exactly a Sotera stipulation, the Office nonetheless recognizes that such stipulations further mitigate concerns of potentially conflicting decisions and duplicative efforts between us and the district court. See Director’s Interim Procedure, at 7–8.

Indeed, at this stage, CamelBak chooses not to address Trove’s showing in this regard, instead arguing that “the construction of ‘closure retention mechanism’ is irrelevant because [Trove] fails to show lug members 15 and 16 are configured to meet other limitations of claims 5 and 19.” Prelim.

“We decline to adopt Patent Owner’s implicit construction that would require “selecting an entity pair from” all of the entity pairs of “said plurality of transport entities.” Contrary to Patent Owner’s arguments addressing the claim language, the plain language of claim 1 does not require the selection to be from all of the entity pairs of the plurality of transport entities for which an overall cost has been determined. The plain language of claim 1 also does not preclude the selection to be from a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined. Rather, dependent claim 9, through its dependence on claims 1 and 4, explicitly allows for the selection to be from a subset of the entity pairs of the plurality of transport entities. Patent Owner’s arguments advocate for the importation of limitations from the ’821 Patent Specification into the claim––namely the disclosure that all entity pairs of transport entities examined in step 220 of Figure 2 are input to the entity pair selection step 230. See PO Sur-reply 4. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.2d 1182, 1186 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). An extraneous limitation is “a limitation read into a claim from the specification wholly apart from any need to interpret what the patentee meant by particular words or phrases in the claim.” E.I. du Pont de Nemours, 849 F.2d at 1433. Accordingly, we construe “selecting an entity pair from said plurality of transport entities based at least upon said overall cost” according to its plain meaning, the scope of which includes selecting an entity pair from all or a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined.” slip op. at 11

“Based on the entire record and after having considered Petitioner’s citations to Doshi, Guichard, and Dr. Houh’s testimony (Ex. 1003) as well as Patent Owner’s citations to Doshi, Guichard and Mr. Gomez’s testimony, we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to combine the teachings of Doshi with Guichard’s teachings of reoptimization of a LSP path triggered by an network change. See Pet. 20–22, 40–45; KSR, 550 U.S. at 418.

In support, Petitioner contends that “the combination would be within a POSITA’s skillset since Doshi already sets forth the calculation and selection techniques that would be utilized during the reoptimization evaluation.” Id.

According to Petitioner, “since Doshi is already ‘monitoring and updating . . . network topology’ . . . event-based reoptimization evaluation per Guichard, would be directly applicable.” Id.

“require “selecting an entity pair from” all of the entity pairs of “said plurality of transport entities.” Contrary to Patent Owner’s arguments addressing the claim language, the plain language of claim 1 does not require the selection to be from all of the entity pairs of the plurality of transport entities for which an overall cost has been determined. The plain language of claim 1 also does not preclude the selection to be from a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined. Rather, dependent claim 9, through its dependence on claims 1 and 4, explicitly allows for the selection to be from a subset of the entity pairs of the plurality of transport entities. Patent Owner’s arguments advocate for the importation of limitations from the ’821 Patent Specification into the claim––namely the disclosure that all entity pairs of transport entities examined in step 220 of Figure 2 are input to the entity pair selection step 230. See PO Sur-reply 4. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.2d 1182, 1186 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). An extraneous limitation is “a limitation read into a claim from the specification wholly apart from any need to interpret what the patentee meant by particular words or phrases in the claim.” E.I. du Pont de Nemours, 849 F.2d at 1433. Accordingly, we construe “selecting an entity pair from said plurality of transport entities based at least upon said overall cost” according to its plain meaning, the scope of which includes selecting an entity pair from all or a subset of the entity pairs of the plurality of transport entities for which an overall cost has been determined.” slip op. at 11

“Based on the entire record and after having considered Petitioner’s citations to Doshi, Guichard, and Dr. Houh’s testimony (Ex. 1003) as well as Patent Owner’s citations to Doshi, Guichard and Mr. Gomez’s testimony, we are persuaded Petitioner sets forth sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to one of ordinary skill in the art to combine the teachings of Doshi with Guichard’s teachings of reoptimization of a LSP path triggered by an network change. See Pet. 20–22, 40–45; KSR, 550 U.S. at 418. Petitioner asserts that “[t]he results of the combination would have been predictable and there would have been a reasonable expectation of success since Doshi and Guichard both address the same technology.” Pet. 22 (citing Ex. 1003 ¶¶ 63–65). According to Petitioner, “a POSITA would have had a reasonable expectation of success in reoptimizing Doshi’s LSP pair selection because Guichard provides significant implementation details, including when to trigger reoptimization evaluations and how to ‘avoid network instabilities.’” Pet. 22–23 (citing Ex. 1003 ¶¶ 63–65; Ex. 1006, 5).

“We do not agree with Patent Owner’s arguments that the ’740 Patent Specification disavows “any configurations where the user port is fixedly assigned to a specific backplane trace” from the full scope of the claim. Patent Owner’s citations to disclosures in the ’740 Patent Specification do not disparage the prior art, but merely contrast the configurations of the user ports and backplane traces disclosed in the ’740 Patent to “some known network element configurations” and “some conventional network elements.” See Ex. 1001, 1:66–2:4, 5:13–21.

KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) if in evidence, so-called secondary considerations.

“We also do not agree with Patent Owner’s substantive arguments. We agree with Petitioner that, in the flow of data from the core network to the network nodes 24, 26, 28 in Bruckman, there is a selection of a trace 52 out of the group of four traces 52 in order to send data to the appropriate line card 34, link 30, and node 24, 26, 28. We have reviewed Petitioner’s analysis addressing dependent claim 11 (see Pet. 58–63) and find that this selecting a trace 52 out of the group traces 52. For these same reasons, we also do not agree with Patent Owner’s argument that “given that Bruckman discloses a system in which the trace is ‘determined’—and not selected—by the selection of a link 30, a POSITA would understand that Bruckman does not disclose the claimed selections in ‘a single computation.’” PO Resp. 53. More particularly, the analysis addressing claim 11, cited by Petitioner, provides additional explanation that Bruckman’s equipment 22 is a two-level demultiplexer structure with concentrators 50 acting as a first level demultiplexer to select one of four links 30 and switching core 40 acting as a second-level demultiplexer by distributing data frames from the input channel among four separate traces 52. See Pet. 58–59 (reproducing Ex. 1005, Fig. 2 (with Petitioner’s added annotations); citing Ex. 1003 ¶ 137; Pet. 23–27). The cited analysis further explains that Bruckman’s equipment 22 shown in Figure 2 includes a control line from controller 42 to the switching core 40 and control lines to each of the concentrators 50. See Pet. 59–60 (reproducing Ex. 1005, Fig. 2 (with Petitioner’s added annotations); citing Ex. 1003 ¶ 138). According to Petitioner, “[g]iven this well-known, two-level structure, a POSITA would have found it obvious for Bruckman’s [e]quipment 22 to be controlled in a manner consistent with well-known two-level demultiplexer control techniques.” Pet. 59 (citing Ex. 1003 ¶ 138). The cited analysis further explains that “[b]ecause each of the demultiplexing devices (switching core 40 and concentrators 50) in [Bruckman’s] Fig. 2 has one input and four outputs, a POSITA would have found it obvious to control each with a two-bit command signal.” Pet. 60 (citing Ex. 1003 ¶ 139). According to Petitioner, switching core (second-level demultiplexer) to select a trace 52. A different two-bit signal would be used to control the concentrators (first-level demultiplexers) to select a link 30, consistent with known techniques for controlling two-level demultiplexers. Such techniques . . . would have been in the background knowledge of a POSITA. Pet. 61 (citing Ex. 1003 ¶ 139; Pet. 33); see Pet. 62–63 (reproducing Ex. 1007, Fig. 5.17(a) (with Petitioner’s annotations added); citing Ex. 1003 ¶¶ 139–141).” slip op. at 34
