“We agree with Patent Owner and find that “computer network protocols” is correct in light of the ’072 patent’s disclosure and claim 1. In particular, the ’072 patent teaches that it “generally relates to [USB] connectivity between, for example, mobile consumer devices and vehicle electronic systems.” Ex. 1009, 1:21–23. And the ’072 patent’s teachings focus on common network components (e.g., hub, bridge, ports) and common networking concepts (e.g., master/slave network architecture and bridging) which are used in the USB context, rather than detailed aspects (e.g., signal timing, signal levels, power levels) of the USB protocol. See generally Ex. 1009; see also Ex. 1084, 103:21–104:2, 104:24–105:4; Pet. Reply 4 (citing Ex. 1084,7 100:17–101:12 (acknowledging that Dr. Houh testifies that one of ordinary skill in the art “would know basic USB concepts like bridging, master/slave architecture, etc.”), 102:3–8, 103:21– 104:2, 104:24–105:4). Likewise, claim 1 repeatedly recites “USB,” but does so to identify that all of the components of the data system (i.e., USB ports, USB hub, USB bridge, USB host, USB multiplexing switches) employ the USB protocol. Ex. 1009, 9:15–10:18. As the ’072 patent teaches, “USB 7 Houh Deposition Tr. (2024/12/18, Day 1). technology . . . [wa]s commonly available, familiar to the end user, cost effective and ubiquitous.” Id. at 1:35–37. Thus, although the ’072 patent is taught in the USB context, “computer network protocols” concepts are the focus. For these same reasons, we find unavailing Petitioner’s argument that one of ordinary skill in the art “would have been well-versed in USB standards (including the USB 2.0 and 3.0 Specifications and the OTG Supplement) and the design/deployment of USB hosts, USB devices, and USB hubs, including suitable environments for USB systems.” Pet. 26.” slip op. at 11

In other words, “[a] presumption of nexus requires both that the product embodies the invention and is coextensive with it.” Id. at 1211 (citing Brown, 229 F.3d at 1130). Patent Owner fails to show either of these requirements. First, Patent Owner argues that in his Supplemental Declaration, Dr. Houh “provides on a per limitation basis how [Patent Owner]’s dual role hub meets all limitations of claim 1.” PO Resp. 73 (citing Ex. 2019 ¶ 136).

“c) Summary For the reasons discussed above, Petitioner has made sufficient showings at this stage of the proceeding that the Wilcox-Londergan-Raskin- Wu combination teaches or suggests every limitation in claims 1, 23, and 27 of the ’139 patent, that one of ordinary skill in the art would have had reason to combine those teachings and suggestions to arrive at the inventions recited in claims 1, 23, and 27, and that one of ordinary skill in the art would have had a reasonable expectation of success. Accordingly, Petitioner has demonstrated a reasonable likelihood of prevailing on its challenges to claims 1, 23, and 27 based on the combination of Wilcox, Londergan, Raskin, and Wu.

“one of ordinary skill in the art would have considered “reverting some of the changes that had been made to Lotus Notes R5’s ‘Search Builder’ to make it more similar to Lotus Notes earlier 3.0’s ‘Query Builder.’” Prelim. Resp. 16. The issue, however, is not whether “over the years Lotus Notes moved away from a unified search field[,]” as Patent Owner suggests. Id. at 14. The issue is what “inferences and creative steps” a person of ordinary skill in the art would have employed, based on Wilcox and Londergan, when designing a new method and system for search indexing. KSR, 550 U.S. at 418. Petitioner’s argument is that one of ordinary skill in the art would have been motivated to consider Wilcox and Londergan together in order to “obtain a more complete and comprehensive understanding of the Lotus Notes system,” which in turn would have inspired certain inferences and creative steps that would have resulted in the portions of the claimed invention allegedly disclosed in Wilcox and/or Londergan.

“art. Prelim. Resp. 30–34. Limitation [1.10] reads, “wherein the first and second partial search strings are separated by a string separator character in the first search field.” Ex. 1001, 30:8–10.

We are not fully persuaded by Petitioner’s argument. In particular, the evidence does not support Petitioner’s argument that a Boolean operator such as “AND” is a string separator character. Patent Owner has pointed to intrinsic and extrinsic evidence demonstrating that a string separator character consists of just one character.16 Consequently, based on the current record, for the purposes of this Decision we preliminarily construe the term “string separator character” to mean “a single-character string separator.” The parties are invited to address the appropriateness of this construction in future briefing. If Boolean modifiers are excluded from the definition of a “string separator character,” then the Londergan Search Bar and Search Builder features, which accept only Boolean operators, do not teach or suggest 16 As Patent Owner argues, the intrinsic evidence does not support this interpretation of the claim language. Prelim. Resp. 31–32. “First, the ’490 patent distinguishes between string separator characters (such as space, comma, etc.) and ‘modifiers’ (such as AND, OR, NOT, etc.).” Id. at 32; compare Ex. 1001, 31:14–17 (claim 12, “string separator character”), with id. at 32:19–23 (claim 20, Boolean “modifiers”).

Even Petitioner acknowledges in a footnote that it may not be appropriate to include the Boolean AND operator in the definition of “string separator character.” Petitioner argues: To the extent Patent Owner argues the Boolean AND operator is not a string separator character (which Petitioner does not acquiesce is appropriate), it would have been obvious to a POSITA when implementing Raskin’s teachings to perform the search incrementally to use a single-character string separator character, such as a plus sign, as was known in the art (e.g., EX1057, 60, 109, 129, 151), or a comma, as described by the Lotus Notes references (EX1059, 159-165), at least because a POSITA knew that a goal of the incremental search is to minimize the number of characters the user has to enter before obtaining the desired search results. 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. The Wilcox Query Builder, however, does teach multiple search strings separated by a string separator character, specifically a comma. Id. at 163 (“If you want to search for documents that contain all of several words, type them in this box, separated by commas.”).

“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. On the current record, we find Petitioner has demonstrated that one of ordinary skill would have been motivated to modify the combination of Lotus Notes references according to those teachings in Raskin. slip op. at 23

“Ex. 1001, 4:46–50. This passage indicates that the interconnect can be a network on a chip and the network on a chip can include wires and buses. That does not necessarily mean that the interconnect can be just wires or buses; rather, it discloses that the interconnect can include wires and buses. In context, the disclosure regarding wires and buses does not support construing the corresponding structure broadly enough to encompass just wires and buses. The networks that constitute the corresponding structure, however, could include networks with wires and buses. Therefore, we agree with Patent Owner that the corresponding structure for the interconnect means should not include a mere bus, switch, and point-to-point wire and instead find that the corresponding structure under 35 U.S.C. § 112 ¶ 6 is a network, which the ’052 patent describes as a multi-hop interconnection between modules separated by one or more network nodes. See Ex. 1001, 2:33–37. Because this structure corresponds to the construction of “interconnect means” proposed by Patent Owner and adopted by the district courts in the TI and Qualcomm litigations (see supra Section III.C.3.b), and we do not rely in our analysis below on a recourse to “equivalents thereto” as permitted by § 112 ¶ 6, we note that our ultimate conclusions on the unpatentability of the challenged claims would be the same if § 112 ¶ 6 did not apply. iii.

Patent Owner, however, did not raise with the Board, prior to filing its Preliminary Response, any concern with the manner in which Petitioner formatted its Petition. As a result, Patent Owner did not avail itself of the opportunity to seek relief to address any alleged undue prejudice short of denying the Petition through, for example, an increase in the word count for its own brief.

“In sum, Petitioner maintains a narrower construction of “magneto coupling” is correct, and alleges grounds of unpatentability based on both its narrower proposed construction (a construction encompassed by the broader construction), as well as based on the broader construction that Patent Owner does not dispute. We, therefore, find no merit to Patent Owner’s argument that Petitioner’s contention “contradicts itself” or fails to present a “prima facie obviousness position.” See Prelim. Resp. 3. Patent Owner does not dispute the broader construction applied by Petitioner, which encompasses the narrower construction Petitioner proposes. For purposes of this Decision, we apply the broader construction of “magneto coupling,” which encompasses generating a rotating field either by rotating magnets or by an electromagnet / stator.” slip op. at 26

“axially adjacent.” In particular, Petitioner argues in connection with mapping cited art to challenged claims for the Wampler and Akamatsu asserted grounds that “a magnetic element sealed within a rotor is . . . ‘axially adjacent.’” Pet. 20 n.6. Petitioner fails to point to any intrinsic evidence to support this construction. Rather, Petitioner alleges that Patent Owner took this position in the parallel litigation in a chart mapping claim 1 to accused products. Id. (citing Ex. 1019,6 5–7). Petitioner does not explain how Patent Owner’s chart supports Petitioner’s construction here. See id. at 6 Petitioner identifies this exhibit as “Exhibit 13 of Complaint, dated November 27, 2023,” which comprises a claim chart mapping accused products to claim 1. when “a magnetic element [is] sealed within a rotor,” it necessarily means being “axially adjacent,” as Petitioner alleges. See Ex. 1019. Rather, we agree with Patent Owner that this chart instead labels product components that are adjacent to one another as measured along a central axis. Prelim. Resp. 21 (citing Ex. 1019, 6–7). In addition, we agree with Patent Owner that “[t]his [mapping] is in accordance with the plain and ordinary meaning of the claim terms and does not suggest that any component ‘sealed within’ another component would categorically be axially adjacent thereto.” Id. We note that Petitioner applies the plain and ordinary meaning of “axially adjacent” for other asserted grounds, arguing that components which are adjacent to one another along a central axis are “axially adjacent.” E.g., Pet. 55–57. Accordingly, we find, for purposes of this Decision, that the plain and ordinary meaning of “axially adjacent” is being adjacent to one another as measured along a central axis, and does not mean a magnetic element sealed within a rotor.

“would have found it obvious to include Wampler’s “techniques related to its axially aligned inflow tube” in the HeartMateIII device taught by Bourque. Pet. 81–88. Petitioner argues that Wampler teaches an arrangement for which “[g]ood anatomic compatibility is possible . . . fitting well between the apex of the heart and the adjacent diaphragm.” Id. at 83 (quoting Ex. 1008 ¶ 76) (alterations in original). Petitioner reasons that applying Wampler’s arrangement to Bourque combines old elements performing known functions yielding expected results. Id. at 83–84. According to Petitioner, a person of ordinary skill in the art would have known from Wampler that an axial inflow, as taught by Wampler, would have improved blood flow for the device of Bourque by eliminating the flow restrictive elbow in Bourque. Id. at 84 (citing Ex. 1003 ¶¶ 648–649; Ex. 1007, 2; Ex. 1008 ¶¶ 75–76). Petitioner contends that Bourque recognized certain components, including inflow components, were the cause of clinical troubles, and that Wampler “taught how to eliminate these components that caused clinical troubles–using the inlet to also ‘serve[] as the inflow canula.’” Id. at 85–86 (citing Ex. 1003 ¶¶ 741–747; Ex. 1007, 1, 5; Ex. 1008 ¶¶ 75–76). Petitioner also argues that a person of ordinary skill in the art would have understood Wampler’s arrangement would have reduced “rates of infection” by avoiding placement of the pump in a preperitoneal pocket person of ordinary skill in the art “would have adhered to the express teachings of [Wampler], which focused on ‘[g]ood anatomic compatibility’ so that the device ‘fit[s] well between the apex of the heart and the adjacent diaphragm,’ eliminating the need for a peritoneal pocket dissection associated with increased rates of infection.” Id. at 86–87 (citing Ex. 1003 ¶¶ 651–654; Ex. 1008 ¶ 76) (second and third alterations in original). Petitioner reasons that a person of ordinary skill in the art would have had a reasonable expectation of success because the asserted combination of Bourque and Wampler “would ‘fit[] well between the apex of the heart and the adjacent diaphragm’ due to the pump’s ‘development as a compact’ device and the existence of several similar LVADs that fit well at that position.” Id. at 87 (citing Ex. 1003 ¶¶ 652–655; Ex. 1007, 5). Lastly, Petitioner argues that the asserted combination would have been obvious to try, because “there were a finite number (i.e., two) [of] options for LVAD implantation: the device would be implanted at a preperitoneal pocket, or at the cardiac apex.” Id. at 87–88 (citing Ex. 1003 ¶ 656). At this stage, we find Petitioner’s arguments persuasive, and find that Petitioner has provided sufficiently articulated reasoning with rational underpinning to support combining Wampler and Bourque’s teachings in the manner Petitioner does.” slip op. at 20

“Magnetic Device” and “Magnetically Driven Rotor” along a “Central Axis”. Ex. 1019, 6. We find nothing in Exhibit 1019 that defines “axially adjacent” to mean “a magnetic element sealed within a rotor,” as Petitioner alleges. In this regard, Patent Owner argues as follows: Exhibit 1019 contains no mention of “a magnetic element sealed within a rotor” or a contention that such a configuration would represent an “axially adjacent” orientation of such components. Instead, [in Exhibit 1019], Patent Owner illustrates a Petitioner product and labels components identified as the claimed magnetically driven rotor and first magnetic device that are adjacent to one another as measured along a central axis. [See Ex. 1019 at 5]. This is in accordance with the plain and ordinary meaning of the claim terms and does not suggest that any component “sealed within” another component would categorically be axially adjacent thereto.” slip op. at 29
