“review of claims 1–17, 20, 21, 24–26, and 29–34 of the ’682 patent. Paper 2 (“Pet.”), 1, 3. Patent Owner, Hangzhou DAC Biotech Co., Ltd., filed a Preliminary Response (Paper 9, “Prelim. Resp.”). We initially determined that the information presented in the Petition did not establish a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims, and did not institute inter partes review. Paper 17. Petitioner requested Director review of our decision denying institution (Paper 18 (“Request”)). The Director delegated review of the decision to a Delegated Rehearing Panel (“DRP”). Paper 19. Patent Owner was granted the option to file a response to Petitioner’s Request (Paper 22 (“Request Resp.”)). The Delegated Review Panel vacated our decision and remanded the case to this panel with a revised claim construction for claim 1. Paper 23 (“DRP Dec.”).

“Accordingly, in the context of Chang, a POSITA would have been motivated to implement dual-role ports by including a switch (e.g., multiplexer or crossbar) that connects the dual-role port(s) directly to the hub’s upstream port (when the consumer product is configured as a device, i.e., path 48) or to the hub through the bridge (when the consumer product is configured as host, i.e., path 54. Id. at 40–41 (citing Ex. 1013 ¶¶ 182–187). Petitioner’s argument that a skilled artisan would have been motivated to modify Chang to include switching functionality as taught by Chang II and supported by other substantial evidence appears well-reasoned and well-supported. Petitioner argues that “[a] POSITA would have been further motivated to improve Chang in view of Chang II, because Chang II expressly states its relevance to USB hubs.” Pet. 41 (citing Ex. 1013 ¶ 181; Ex. 1015 ¶¶ 27, 40). And, Petitioner argues that “while Chang discloses little regarding its bridge (EX1014, [0020]), Chang II details various aspects of its bridge (EX1015, Title, Figs. 1-2 and 5).” Id. In support of this argument, the Petition provides: Importantly, Chang II further details exemplary switching for either a host- or device-product: “the main feature is the provision of two different transmission paths, so that by automatically detecting the type of device connected (host or slave) the present invention can switch to the proper transmission path.” EX1015, [0021]. In other words, Chang II describes “switch[ing]” to connect a “bridge” transmission path (when the product is host) or “bypass” path (when the product is device). Id., Figs. 1, 5, [0013]. And Chang II further discloses “detection unit 134” for detecting whether the consumer product is host or device. Id., [0038]. Id. (bracketed material in original, footnote omitted). Petitioner contends that “[a]ccordingly, a POSITA would have been motivated, with a high expectation of success, to route the dual-role ports (and products attached thereto) to the appropriate path using a switch.” Id. at 41–42.

“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

“that the asserted objective evidence is tied to a specific product that ‘embodies the claimed features, and is coextensive with them.’” Id. (quoting Brown & Williamson Tobacco Corp. v. Philip Morris, Inc., 229 F.3d 1120, 1130 (Fed. Cir. 2000)). 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). Notably, Patent Owner cites to a single paragraph in this declaration, without providing any specific arguments in its Response that its product practices claim 1. Id. Rather, Patent Owner incorporates its arguments by reference, which is not permitted. See 37 C.F.R. § 42.6(a)(3) (“Arguments must not be incorporated by reference from one document into another document.”).

“claims a method of treating a human patient with colorectal cancer having certain characteristics using pembrolizumab and the main prior art reference cited by Petitioner discloses testing pembrolizumab to treat human patients. (See Ex. 1001, 25:40–50, Ex. 1005; see Decision 8–9.) Accordingly, the relevant field of Patent Owner’s claims is treating human patients, as well as testing existing compounds. Neither party directs us to evidence of the level of skill in the art beyond what we considered for institution of trial. In the Decision to institute trial, we determined that the level of skill in the art relevant to the claims of the ’393 patent is not limited to knowledge of and experience with conducting research relating to oncology or developing and conducting clinical trials. (See Dec. 8–9.) We determined that the level of skill also includes knowledge of and experience with treating colorectal cancer patients with immunotherapy compounds, identifying the conditions these patients may have, and understanding the literature regarding clinical trials for such colorectal cancers and the associated conditions and immunotherapy.

“1 requires a causal relationship wherein the patient must be tested for MSI-H and, if he or she is determined to be MSI-H or dMMR, then the patient is treated with 10 mg/kg of pembrolizumab every 14 days. We further agree that this relationship is different than the use of the term “after” in claims 7, 20, and 27, wherein patients must be treated with a different cancer therapy, and wherein the cancer must have later progressed for the treatment to be within the scope of these claims. (Ex. 1001, 25:66–7, 26:44–46, 26:63–64.) In claim 1, a biological sample from the patient must be tested to determine if the cancer is MSI-H and, if so, the patient is treated with a therapeutically effective amount of pembrolizumab. For this reason, if the prior art teaches the limitations of 1) testing a biological sample obtained from a patient having colorectal cancer to determine that the patient’s colorectal cancer is microsatellite instability high or mismatch repair deficient, and 2) treating the patient with a therapeutically effective amount of pembrolizumab if the patient’s colorectal cancer is determined to be microsatellite instability high or DNA mismatch repair deficient, the art anticipates claim 1.

“IBM200 and Kuhno would have made it obvious for a POSITA to commission RFID tags with unique serial numbers partitioned into MSBs and bits of lesser significance. See Pet. 34–39; Ex. 1005 ¶¶ 167–176. However, on this record, Petitioner has not sufficiently shown that the POSITA, having read IBM200 and Kuhno, would have been led to create a serial number space in which the limited number of “most significant bits” uniquely corresponds to those bits assigned to an allocated block of serial numbers, as recited in limitation [f].” slip op. at 25

The Board denied institution of IPR on all challenged claims, exercising § 314(a) discretion under Fintiv because the parallel litigation was advanced and trial would precede a final written decision.

“Under the latest applicable guidance, Petitioner’s Sotera stipulation “is highly relevant, but [is] not . . . dispositive by itself.” CAPJ Memo at 2– 3. Accordingly, we consider Petitioner’s stipulation “as part of [our] holistic analysis under Fintiv.” Id. at 2. In theory, Petitioner’s stipulation could “mitigate[] any concerns of duplicative efforts between the district court and the Board, as well as concerns of potentially conflicting decisions” regarding unpatentability/ invalidity. Sotera, Paper 12 at 19. We note that Petitioner’s initial invalidity contentions included the two asserted references here, Bennett and Nashida. Although Petitioner served those contentions before the filing of the instant Petition—in which it proffered its stipulation—we cannot discern from the instant record whether Petitioner’s present invalidity positions in the underlying litigation incorporate any aspects of its grounds here based on Bennett and Nashida. Still, we view Petitioner’s stipulation as significantly mitigating potential conflict given the likelihood that the court would hold Petitioner (and its privies) to Petitioner’s representations made here.5” slip op. at 18

Under 35 U.S.C. § 314(a), we may not authorize an inter partes review unless the information in the petition and the 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.” The Board, however, has discretion to deny a petition even when a petitioner meets that threshold. Id.; see, e.g., Cuozzo Speed Techs., LLC v. Lee, 136 S.

“controller” that “receive[s] an identifier for identifying a second video content from [an] external mobile terminal” and “acquire[s] the second video content via the internet using said identifier.” Ex. 1001, 20:29–31, 20:46–47, 20:52–55 (alterations and emphasis added). In the Bennett obviousness ground, Petitioner cites Bennett’s control signal that directs display of a video stream on a television screen for teaching the recited “identifier.” Pet. 32 (citing Ex. 1004 ¶ 32). Petitioner further cites Bennett’s teaching of an Internet server as a media source for teaching the “acquire[s]” limitation. Id. at 34 (citing Ex. 1004 ¶ 55). Petitioner alternatively cites its declarant’s testimony and contends that it would have been obvious “to use an identifier such as URL in Bennett’s system to retrieve video content from the Internet.” Id. at 35 (citing Ex. 1003 ¶ 87). Yet Patent Owner’s arguments (see Prelim. Resp. 59–64) call into question whether Bennett teaches or suggests the use of either Bennett’s control signal or a URL to “acquire the second video content via the internet.” In addition, we preliminarily agree with Patent Owner that Petitioner’s arguments regarding the URL “focus on justifying an example of what an identifier could be, and fail[] to address a scenario that would justify the receipt of a URL from a phone/remote” in Bennett’s system. Id. at 63. Petitioner’s further contentions for these limitations in the Bennett– Nashida obviousness ground (see Pet. 73–75) do not necessarily cure the deficiencies mentioned by Patent Owner. Petitioner contends that “Nashida discloses the use of identifiers, such as URLs, for retrieving internet content” and cites Nashida’s teaching of “‘controller 1010 transmit[ting] a command of requesting a transmission of a URL’ for retrieving and displaying web content on a display apparatus.” Id. at 73 (quoting Ex. 1005 ¶ 120). Yet, according to Patent Owner, Nashida appears to show the URL moving in the opposite direction of Petitioner’s intended mapping: “It is therefore the image display apparatus (the alleged ‘display apparatus’) that sends the URL to the remote controller . . . , and not the other way around, as claimed by Petitioner.” Prelim. Resp. 67 (citing Ex. 1005 ¶ 1216). At the very least, these issues preclude a finding of “particularly” slip op. at 20

“September 22, 2025, which is less than four months after the statutory deadline for this Decision and “almost eight months before the projected statutory deadline for a final written decision.” Prelim. Resp. 25 (citing Ex. 2004). Accordingly, the trial is currently set to occur several months before any Final Written Decision in this case will issue. Although trial delays are a possibility, there is no evidence before us that would indicate the likelihood of a trial postponement.

“transmits, over the USB cable, a first signal to the digital camera for causing the digital camera to output compressed first image information.” Petitioner addresses that requirement by asserting Lawther’s interface circuit “can also be adapted to enable exchange data with a connected external device.” Pet. 39 (quoting Ex. 1004 ¶ 50). Although Lawther may “exchange data,” supporting that signals may be sent to a connected camera, Petitioner does not establish that such a signal would have been used as claimed. It may be that such a signal is inherently present in the interactions Lawther describes, but Petitioner does not assert or establish so, only that Lawther has the capability to “exchange data” with a connected camera. Because of this potential weakness in Petitioner’s showing, we cannot conclude that the Petition presents a particularly strong challenge.” slip op. at 9

Petitioner stipulates not to pursue in the Texas litigation “the same grounds or any grounds that could have reasonably been raised before the PTAB.” Pet. 68.
