Pet. 24 n.7. limitation [1.10].17 See Ex. 1061, 140–42. The Wilcox Search Bar similarly is limited to strings separated by a Boolean operator. See Ex. 1059, 160–62.

“extreme technical difficulties with even using incremental searches.” Prelim. Resp. 21, 25 (citing Ex. 1021, 126). Patent Owner argues that “[a] POSITA is not motivated to undertake a modification of the prior art with something that the art teaches would be difficult or impossible to do.” Id. at 21 (citing Natera, Inc. v. NeoGenomics Labs., Inc., 106 F.4th 1369, 1377–78 (Fed. Cir. 2024)). We do not interpret Raskin in this manner. Patent Owner points to a passage in Raskin stating, “almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches.” Ex. 1021, 126. There is a difference, however, between “difficult to implement” and “difficult to use.” For the end-user, Raskin concludes that “[f]rom the point of view of interface engineering, the advantages of incremental searching are so numerous and the advantages of delimited searches so few that I can see almost no occasions when a delimited search would be preferred.” Id. at 126 & n.7 (“A search is either incremental or excremental.”). It is reasonable to conclude that one of ordinary skill would have been motivated to choose a search method that offered numerous advantages to end-users. Finally, Patent Owner argues that “Raskin’s entire philosophy to user interfaces was incompatible with Lotus Notes.” Prelim. Resp. 22–25. According to Patent Owner, “Lotus Notes is all about centralized collaboration around documents, files, and file structures[,]” while Raskin “goes in a completely different direction, espousing the elimination of filenames and ‘hierarchical file structures’ including directories and folders.” Id. at 23 (citing Ex. 1021, 119). Patent Owner claims that modifying the Lotus Notes references with Raskin would “effectively render[] Lotus Notes’ functionality of hierarchical viewing of and responding to documents unusable.” Id. Petitioner, however, does not propose to incorporate Raskin’s views on hierarchical file structures into the combination of Wilcox and Londergan. It is not necessary for the entirety of Raskin’s teachings to be physically compatible with the Lotus Notes systems described in Wilcox and Londergan. Orthopedic Equip., 702 F.2d at 1013 (“Claims may be obvious in view of a combination of references, even if the features of one reference cannot be substituted physically into the structure of the other reference.”); In re Sneed, 710 F.2d at 1550. Raskin is cited for one purpose: its teachings regarding incremental search.

“The parties’ dispute on this issue turns on claim construction. Petitioner’s approach requires we read “accumulation” as updating transmission power for each received TPC command. That is consistent with some aspects of the ’153 patent’s description. See Ex. 1001, 9:29–42 (“[S]tep is the magnitude of the amount added to an accumulator upon receipt of each TPC command. . . . [T]he transmit power PTx(k) may be updated each time a new TPC command is received.”). Patent Owner’s approach requires only that TPC commands cumulatively affect transmission power. That also appears consistent with the ’153 patent’s description. See id. at 9:35–36 (“The transmit power PTx(k) may be updated for every frame period.”). Based on those disclosures, it appears that the Specification supports Patent Owner’s broader construction. We need not resolve the “accumulation” claim-construction dispute at this stage, because Petitioner’s Zeira-based ground justifies institution, as discussed below. The parties should address the proper construction for “TPC command accumulation” in the instituted trial.” slip op. at 8

“We do not agree with Patent Owner that the present record shows Andersson’s and Khan’s approaches couldn’t or wouldn’t be combined in the manner Petitioner asserts. Although shared-channel applications may have motivated Khan’s approach, it seems that scheduling grants applicable to a particular UE could be transmitted to that UE along with Andersson’s TPC commands. Thus, Patent Owner does not undermine Petitioner’s prior-art combination on the present record. The additional record developed through trial may ultimately support Patent Owner on this point, but at present, this argument does not justify denial of institution. Patent Owner additionally takes issue with Petitioner’s asserted benefits such as “allowing for a larger number of active wireless units,” reducing complexity, and reducing latency. Prelim.

“Patent Owner submits that the asserted combination is unworkable and that skilled artisans would not have made it because Andersson’s DPCCH is a dedicated channel sent to a single UE, whereas Khan’s TPC commands and scheduling grants are sent using a shared channel—“a channel that is shared by the UEs attached to a particular base station.” Prelim. Resp. 20. Because Khan’s TPC commands and scheduling grants “are intended for different UEs that share the channel,” unlike Andersson’s TPC commands in a dedicated channel, Patent Owner asserts, “the two frame structures cannot be combined in the manner Petitioner suggests.” Id. at 20–21. Although Andersson describes “other bits” in its data structure, Patent Owner asserts that those “would necessarily be intended for the UE that the DPCCH is dedicated for” and would not work for Khan’s scheduling grants.

“B. Level of Ordinary Skill in the Art Petitioner argues that at the time of the ’088 patent (January 2006), a person of ordinary skill in the art would have had “a bachelor’s degree in computer science, computer engineering, electrical engineering, or equivalent training, and approximately four years of experience working in the field of network communications, including experience with [Multiprotocol Label Switching (MPLS)] tunnels and bandwidth allocation,” where “[a]dditional work experience can substitute for specific educational background, and vice versa.” Pet. 12 (citing Ex. 1003 ¶¶ 20–21). Petitioner further contends that a person of ordinary skill in the art would have been knowledgeable and familiar with the network communications technologies discussed in [the Specification of the ’088 patent], including bandwidth reservations, quality of service techniques, routing protocols (including Open Shortest Path First (OSPF)), tunneling protocols (including [MPLS]), resource reservations (including Resource ReSerVation Protocol (RSVP)), traffic engineering (including relevant extensions to OSPF, IS-IS, and RSVP), and ring networking standards (e.g., Synchronous Optical Network (SONET) and resilient packet ring (RPR) defined by IEEE 802.17). Id. Patent Owner states that “Petitioner’s definition . . . is acceptable for” purposes of its Preliminary Response. Prelim. Resp. 8 n.3. Based on the record presented, including our review of the ’088 patent and the types of problems and solutions described in the ’088 patent and cited prior art, we agree with Petitioner’s proposed definition of the level of ordinary skill in the art and apply it for purposes of this Decision.” slip op. at 9

We conclude 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) (emphasis added)).” slip op. at 10

“Patent Owner, however, does not explain sufficiently why any of these issues demonstrate a failure to teach limitation [1.1]. We understand Petitioner’s position to be that Dziong identifies “two or more candidate routes” (i.e., A-B-C-D and A-C-D) for a “new connection” (i.e., a new recovery path to protect primary path SRLG 4 in the event of failure) with a “requested bandwidth” (i.e., 15 units) sufficient to protect against failure. See Pet. 27–31 (citing Ex. 1005 ¶¶ 36, 70, 89, 90, 104, 105). The 15 units are the “units of demand” on SRLG 4 that must be protected. Ex. 1005 ¶¶ 89 (“[E]ach solid line represents all of the demands that have the same link-detour path, which is represented by a corresponding broken line. For example, solid line 606 in SRLG 4 corresponds to one or more demands totaling 15 units of bandwidth between nodes A and D.”), 90. A link in a potential recovery path for that demand on SRLG 4, therefore, would need to have “sufficient recovery bandwidth” to protect against failure (i.e., at least 15 units). Id. ¶¶ 36, 104. That is reflected in the “SRLG 4 failure” column of Figure 6(b) for link A-B (part of the A-B-C-D recovery path shown in blue in Figure 6(a) above). On this record, we do not see why the fact that link A-B also protects against failures of SRLG 3 and 5 and has its own 12 units of demand, or the fact that SRLG 4 also has another 24 units of demand (which link A-B does not protect against), contradicts Petitioner’s position regarding Dziong and limitation [1.1]. See id. ¶¶ 89–90 (“link A-B is not part of the link-detour path for the other 24 XC units of demand on SRLG 4”). At this stage, we find that Petitioner has made a sufficient showing that Dziong teaches limitation [1.1]. Therefore, we need not evaluate any additional arguments regarding Sathyanath at this time. See Pet. 31–32; Prelim. Resp. 14–16.” slip op. at 23

“We disagree based on the current record. Dziong refers to both “link-based” and “path-based” recovery. Ex. 1005 ¶¶ 6–8. And the two methods are similar in various ways, as Dziong recognizes. See, e.g., id. ¶¶ 69 (“While some of the algorithms utilized in a link-based scheme are related to path-based recovery algorithms, there are significant modifications and special considerations that are made in the case of link-based recovery.”), 103 (“In some areas, the issues associated with recovery path calculation for link-based recovery [are] analogous to recovery path calculations for path-based restoration . . . .”). Dziong also purports to incorporate Sathyanath’s application by reference. Id. ¶ 1. And, as Petitioner points out, the references have similar disclosures and similar discussions of bandwidth sharing. See Pet. 1, 20–22; Ex. 1005 ¶¶ 10–12, 36–39, 60, 65, 88; Ex. 1006 ¶¶ 4, 12–13, 41–45, 200. Thus, on this record, we disagree with Patent Owner that a person of ordinary skill in the art would not consider combining the teachings of Dziong and Sathyanath. See In re Applied Materials, Inc., 692 F.3d 1289, 1298 (Fed. Cir. 2012) (“A reference must be considered for everything that it teaches, not simply the described invention or a preferred embodiment.”); In re Hyon, 679 F.3d 1363, 1366 (Fed. Cir. 2012) (affirming an obviousness determination where two “references both teach processes directed to making the same class of products” and minor differences between the disclosures did not “negate the motivation to combine”). Second, Patent Owner argues that Petitioner “fails to identify specific teachings in Sathyanath that a [person of ordinary skill in the art] would have been motivated to implement in Dziong with a reasonable expectation of success” and “does not explain how the features would have been combined or why there would have been a reasonable expectation of success in doing so.” Prelim. Resp. 11. Patent Owner, however, only mentions Petitioner’s introductory statement regarding reasons to combine and does not address the substance of Petitioner’s arguments for claim 1, where Petitioner explains how it is relying on Sathyanath as a secondary reference. See Prelim. Resp. 10–11 (citing Pet. 22–23). For example, regarding the “sharing definition” of limitation [1.2], Petitioner argues that because Dziong only gives “limited details about the data format used for sharing” reserved bandwidth information, “it would have been obvious to consider . . . Sathyanath’s examples,” relying on two particular alleged “sharing definition[s]” in Sathyanath (i.e., the “aggregate node-link vector” and “TE/Share database”). Pet. 36–39. Based on the current record, we preliminarily find that Petitioner has made a sufficient showing, supported by the testimony of Dr. Mir, that a person of ordinary skill in the art would have been motivated to use such data formats to share reserved bandwidth information in the system of Dziong, with a reasonable expectation of success. See id.; Ex. 1003 ¶¶ 38–39, 72–79.” slip op. at 38

“to combine Johnson and Moss is inadequate. See Prelim. Resp. 20–24. We tend to agree. In the “Motivation to Combine Johnson and Moss” section, the Petition first asserts that “Johnson and Moss are in the same field of endeavor,” which is insufficient without more to provide a motivation. See, e.g., Sisvel Int’l S.A. v. Sierra Wireless, Inc., 82 F.4th 1355, 1364 (Fed. Cir. 2023). The Petition then asserts that “[t]o provide enhanced flexibility, [one of ordinary skill in the art] in possession of Johnson would look to Moss to incorporate a plurality of delay elements to the data strobe signal.” Pet. 22. This is not persuasive because (a) Petitioner argues that Johnson already provides a plurality of delay elements, (b) Petitioner fails to explain where or how additional delay elements from Moss would be added to Johnson, and (c) Petitioner fails to explain how or why the modification would “provide enhanced flexibility,” or even what “enhanced flexibility” might mean in 9 “a first sampling circuit to sample the first delayed data signal based on the strobe signal” 10 “a second sampling circuit to sample the second delayed data signal based on the received strobe signal” this context. Petitioner also argues that “Moss further discloses that the size of the data path – i.e. the number of data pins in each data path – is a design choice well within the knowledge and ability of a POSITA, and expressly recites examples of 4, 8, and 16-bit wide data paths.” Pet. 23. We agree that varying the width of the data path would have been within level of ordinary skill and would have depended on the particular application, but the Petition fails to explain how or why that would have made it obvious to incorporate various elements of Moss into Johnson.” slip op. at 19
