See PO Resp. 13 (“[T]he claimed DOCSIS controller must control DOCSIS functions. This does not mean that it must control all DOCSIS functions or all DOCSIS functions identified in the specification.”); Sur-reply 1 (“Under its plain meaning, a ‘DOCSIS controller’ must control or implement one or more DOCSIS functions.”); Tr. 66:19–21 ([Q]: “And as long the controller performs one of those functions that of, for DOCSIS, it qualifies as a DOCSIS – [Petitioner’s Counsel]: “It’s a DOCSIS function [sic, controller] in our point of view.”).

“We do not agree with Petitioner’s obvious to try theory because Petitioner does not show that the “few finite options” were known in the prior art. However, we nevertheless agree with Petitioner that it would have been obvious for the cable modem engine to have been configured to enable upgrades to its software in a manner that is independent of upgrades to the software of the data networking engine. This is primarily because this limitation appears to require little more than that a software update could change the cable modem functionality (e.g., the PacketCable or DOCSIS functionality) without changing the data networking engine functionality (e.g., the CableHome functionality). See Ex. 1001, 3:49–62. Gaspar, for example, shows that one of ordinary skill would recognize that the evolution of standards in this field requires controller upgrades, and a software update addressing only a change in the PacketCable standard (because only that standard had changed, for example) would be an upgrade to the cable modem software that would be independent of any upgrades to data networking engine software. We credit Dr. Kiaei’s testimony that one of ordinary skill “would have understood that two different engines performing two different functions and using two different protocols (DOCSIS and PNA) should be separately upgradeable to address protocol changes independently.” Ex. 1002 ¶ 123.” slip op. at 27

“We agree with Petitioner that use of these ARM processors would have been an obvious design choice, given that they were known to be useful in applications “that demand the highest levels of performance with small size, low cost, and low power consumption.” Ex. 1016 ¶ 8. 5 Put another way, we conclude that claims limiting an otherwise obvious system to off-the-shelf hardware of the type generally suitable for the purpose does not make the subject matter non-obvious. Regarding whether Klein and Kim ʼ678 are analogous art, we find that they are pertinent to the problem confronting the ’775 patent inventors who would have been looking for processors suitable for implementation of the invention, and Klein and Kim ʼ678 indicate that these processors would be suitable in applications that, though different, also implicated similar size, cost, and power consumption considerations. For these reasons, having carefully considered the fully developed record, we conclude that the Petition has established that the combination of Rabenko, Klein, and Kim ʼ678 teaches or suggests use of the claimed ARM processors.” slip op. at 31

Therefore, at this stage of the proceeding, we need not reach Patent Owner’s assertions as to the third alternative argument and evidence Petitioner provides, namely the combination of examples 2), 3), and 4). For completeness, however, we acknowledge that Bucknell does not expressly combine examples 2), 3), and 4), mainly because example 4) only refers back to example 2). However, we note that from a plain reading of Bucknell’s written description it may not be a significant leap to understand that the disclosed combination of examples 2) and 4), with first and second portions 90 and 95 populated in reverse order as taught in example 4), that this combination could be subsequently modified by example 3) to provide a “second iteration . . . based on buffered data.” Ex. 1006 ¶¶ 26–27. In other words, on the current record it is not clear why “the unused resource” of Bucknell’s second portion 95 cannot also “be made available,” to the first portion 90 if the order was simply reversed per the combination of examples 2) and 4). 3. Conclusion as to Claim 1 In summary, we find Petitioner’s arguments and evidence sufficient to show a reasonable likelihood that claim 1 is unpatentable over Eckert in view of Bucknell and Lohr-1. On the current record, we find that Bucknell discloses “a first iteration” based on receiving the priority values for logical channels associated with the MAC-d flows. Ex. 1006 ¶ 26. And, as discussed above, Bucknell’s described “priorities,” are plural, just like the claimed “received parameters.” Ex. 1001, 14:11; Ex. 1006 ¶ 26. In on a priority.” See Ex. 1001, 13:57–14:16.

“We do not agree with Patent Owner that “fixed” or “configurable” requires more than what is agreed to by the parties––i.e., the characteristics and operational parameters of the endpoint are either set prior to operation or can be set during operation. We disagree that the ’972 patent defines “fixed or a configurable endpoint” as “a number of descriptive fields of the endpoint.” Rather column 8, lines 5–6, of the ’972 patent states that “[a]n endpoint is defined by a number of descriptive fields,” which speaks more about the mechanism used to establish the characteristics and operational parameters of the endpoint than it does about how “fixed” or “configurable” would be understood by a skilled artisan. And the fact that an endpoint may be defined by descriptive fields does not inform a skilled artisan that “fixed” or “configurable” requires the endpoint to allow the processing device to correctly interpret and utilize the data from the endpoint. Correctly interpreting and utilizing data may be the goal, but that goal is not turned into a requirement of the claims because the recited endpoint is fixed or configurable. Similarly, there is no basis for making that goal a requirement simply because a fixed endpoint is described as providing basic functionality and a configurable endpoint is described as being configurable by the base unit either while pairing or via the processing device. As a result, we find little merit in Patent Owner’s contention that the language “fixed or a configurable” requires a process for setting up the characteristics and operational parameters of an endpoint within a device so that the processing device can correctly interpret and utilize the data of this endpoint. Patent Owner, however, will have an opportunity during trial to further develop this contention.” slip op. at 11

“Having considered the arguments and evidence presented by both parties at this stage of the proceeding, we are persuaded that there is a reasonable likelihood Petitioners would prevail in showing that Beel discloses or suggests to a skilled artisan a base unit having a transmitter and a first peripheral device having a receiver and at least one fixed or a configurable endpoint, where the at least one fixed or a configurable endpoint is a data source or a data sink which is able to store or emit data, of the functional device exposed or made available on the first peripheral device. Petitioners’ offers evidence, supported by its expert declarant, that the endpoints disclosed in Beel are either fixed, such as a mass storage unit with predefined characteristics, or configurable, such as a virtual audio interface that may change configuration based on driver instructions or use context. Pet. 32–33. As Petitioners point out, the ’972 patent itself acknowledges that Beel’s Figure 11 illustrates a system comprising a combination of vendor-specific and standard endpoints, and further interprets these endpoints to correspond to drivers and host applications used for functionality like screen sharing and audio streaming, which demonstrates a direct conceptual and structural alignment between the ’972 patent and Beel. Id. Furthermore, Petitioner’s evidence demonstrates sufficiently that Beel describes a peripheral device acting as a virtual composite device capable of emulating different functions—such as a USB audio speaker—while rerouting the data stream (e.g., RTP audio stream) over the network. Id. For instance, Petitioners’ evidence demonstrates sufficiently Beel discloses or suggests that audio data can be captured by a virtual sound card interface implemented within the peripheral device, re-encoded, and transmitted to the base unit for playback or synchronization with video content. Id. In addition, Petitioners have demonstrated sufficiently that Beel’s architecture supports the requirement that the endpoint of the functional device—whether it is a camera, microphone, or speaker—is made available through or exposed on the peripheral device. Id. The functional device’s capabilities are effectively rendered accessible to the processing device by way of the peripheral device, which acts as an intermediary. Id. Petitioners’ evidence demonstrates sufficiently that this exposure can occur via logical interfaces, such as USB Audio Class (UAC) virtual drivers, that allow the processing device to recognize and interact with these endpoints using standard protocols. Id. Furthermore, Petitioners show sufficiently Beel discloses that the peripheral device may include software that facilitates communication with and presentation of media content on the processing device, further demonstrating that the endpoints are not only present but also actively used for data transmission. Id. Patent Owner’s arguments, at least at this stage of the proceeding, fail to undermine Petitioners’ showing because they are largely just that–– attorney arguments––without sufficient evidentiary backing and because they lack sufficient clarity regarding how the recited claim language distinguishes Beel’s disclosed system. First, Patent Owner makes several representations that Petitioners misplace its reliance on certain teachings or suggests found in Beel and that Beel does not support the contention Petitioners make, but Petitioners’ positions are backed the testimony of Dr. Almeroth and Patent Owner offers no contradictory evidence for why a skilled artisan would understand Beel differently. And, suffice it to say that, when the declaration of Dr. Almeroth is considered in juxtaposition with the cited evidence from Beel, we have found declarant Dr. Almeroth sufficiently persuasive to demonstrate Petitioner is reasonably likely to prevail on the point. For example, Patent Owner simply argues that “there is no indication in Beel of using any fixed or a configurable endpoint of the functional device exposed or made available on the first peripheral device” (Prelim. Resp. 31), but declarant Dr. Almeroth states that “Beel discloses that a peripheral device can act as a ‘virtual audio device’ using a USB Audio Class (UAC) interface,” which “indicates that endpoints of the functional device are ‘exposed or made available on the first peripheral device’” (Ex. 1002 ¶ 130 (emphasis added); see also id. ¶¶ 128–129). Patent Owner’s argument, without any evidentiary support, does little to undermine the opinion testimony from Dr. Almeroth about what Beel’s teachings would indicate to a skilled artisan.

“a first current through one or more output ports of the at least one output port in a first operating mode,” and “is configured to output a second current capable of starting a vehicle engine through the pair of output terminals in a second operating mode.” Ex. 1001, 8:25–34. Claim 21 has similar first and second operating-mode limitations. Id. at 9:40–46. Patent Owner proposes that “[t]he proper construction for ‘first operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a first current through one or more output ports of the at least one output port, and outputting a second current capable of starting a vehicle engine through the pair of output terminals is inhibited.’” PO Resp. 25. Similarly, Patent Owner argues “[t]he proper construction for ‘second operating mode’ is ‘an operating mode of the portable backup charger wherein the battery pack is configured to output a second current capable of starting a vehicle engine through the pair of output terminals, and outputting a first current through one or more output ports of the at least one output port is inhibited.’” Id. at 27. Patent Owner asserts that claim differentiation supports its construction because dependent claim 3 recites “a third operating mode for outputting the first current and the second current simultaneously,” and “if the battery pack could output the first current and the second current simultaneously in the first operating mode, then there would be no difference between the claimed first operating mode and the claimed third operating mode.” Id. at 26. We disagree with Patent Owner’s constructions because, as Petitioner explains, they wrongly import current-inhibiting limitations beyond the plain language in the claim. Pet. Reply 1. Nothing in the at-issue language addresses inhibiting current. In addition, the claimed first and third operating modes are still distinct without importing additional limitations because outputting just the first current is sufficient for the first operating mode, but not for the third. In other words, whereas the third operating mode requires simultaneity, the first and second merely permit it. Thus, claim differentiation does not support Patent Owner’s construction. Last, although Patent Owner asserts that its construction “is consistent with the specification,” nothing in the cited passages describes inhibiting current. Prelim. Resp. 26 (citing Ex. 1001, 4:30–33, 5:30–33, 5:58–62). Instead, the specification characterizes the modes solely by what the portable charger “can output,” not what is inhibited. Ex. 1001, 4:30–33, 5:30–33, 5:58–62. Thus, we decline to read the first and second operating modes to require the current-inhibiting features that Patent Owner asserts.” slip op. at 6

In addition, we agree with Petitioner that Chen shows the claimed different current paths even under Patent Owner’s construction. Pet. Reply 8–12.

Id. at 23 (citing, e.g., Ex. 1016 ¶ 36 (Takagi referring to “form[ing]” its products shape); Ex. 1014, 9–11 (Cornette referring to “hot stamping”); Ex. 1003 ¶ 48. Petitioner argues that Takagi teaches a strip of base steel having a first and second side. Id. at 23–24 (citing, e.g., Ex. 1003 ¶ 49; Ex. 1016 ¶¶ 13, 36. Petitioner argues that Takagi teaches a coating that is a “diffusion layer” having five phases as depicted by Takagi Figure 2A and explained by Takagi Table 1 (Takagi Fig. 4). Id. at 24–30 (citing, e.g., Ex. 1003 ¶¶ 50–59; Ex. 1016 ¶ 20, Fig. 2A). Petitioner argues that Takagi alone or as modified by Cornette teaches a coating thickness greater than than 30 µm. Id. at 30–31; Ex. 1014, 9; Ex. 1016 ¶ 35; Ex. 1003 ¶¶ 60–61. Petitioner explains why a person having ordinary skill in the art would have had reason to combine teachings of Takagi and Cornette with a reasonable expectation of success. Pet. 11–20 (citing, e.g., Ex. 1003 ¶¶ 31–47; Ex. 1016 ¶¶ 19–37, 47; Ex. 1014, 9; Ex. 1025, 5:17–20; Ex. 1026, 7; Ex. 1034 ¶ 13; Ex. 1055 ¶¶ 2, 7, 14–15, 18, Fig. 3). Based on our review and consideration of the current record, we determine that the information presented sufficiently supports, for purposes of institution, Petitioner’s assertions that Takagi and Cornette teach or suggest each limitation of claim 1. See Pet. 6–31. We therefore determine Petitioner has met its burden to show a reasonable likelihood it would prevail in demonstrating that claim 1 would have been obvious over Takagi and Cornette.” slip op. at 12

“unless the information presented in the petition “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 following findings of fact and conclusions of law are not final, but are made for the sole purpose of determining whether Petitioner meets the threshold for initiating review. Any final decision shall be based on the full trial record, including any response timely filed by Patent Owner. Any arguments not raised by Patent Owner in a timely-filed response may be deemed waived. For the reasons stated below, we determine that Petitioner has established a reasonable likelihood that it would prevail with respect to at least one claim. We hereby institute an inter partes review as to claims 1–30 of the ’602 patent based upon Petitioner’s asserted grounds of unpatentability.” slip op. at 2

“We instituted review of claims 1–4 and 7–18 of the ’483 patent in IPR2024- 01013 after a review of all arguments and evidence presented by the parties, including Patent Owner’s arguments in its preliminary response. For the reasons discussed in the Institution Decision in IPR2024-01013, we determine that Petitioner demonstrates a reasonable likelihood of showing at least one claim of the ’483 patent is unpatentable. Thus, we find that the Petition warrants institution of inter partes review on all claims and grounds set forth in the Petition.” slip op. at 8

“Upon consideration of Petitioner’s arguments, we are persuaded that it is appropriate under these circumstances to join Petitioner to the proceeding in IPR2024-01013. Petitioner’s agreement to accept an “understudy” role and to not actively participate in IPR2024-01013 unless the current petitioner ceases to participate will limit any potential impact on the trial schedule and will avoid increasing the costs or complexity of the proceeding. Therefore, joinder of Petitioner to IPR2025-00359 will further the goals of a just, speedy, and inexpensive resolution of Petitioner’s challenge. 37 C.F.R. § 42.1(b).” slip op. at 10
