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.

“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.

The cited passages disclose foveal image sensors for acquiring both a wide and narrow field of view and having smaller pixel sizes arranged in the central foveal region and larger pixel sizes arranged in peripheral rings about the central region, resulting in sensors that have a high resolution only in the narrow field of view.

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.”). Thus, while we do not accept all of Petitioner’s reasoning, there is evidence to support Petitioner’s overall argument that the proposed combination discloses multiple search strings separated by a string separator character, as we have preliminarily construed the term.” slip op. at 28

“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

At this stage of the proceeding, however, we decline to read into the accepted District Court construction of “integration time” the additional negative limitation that Patent Owner proposes––i.e., the term “scene” excludes a photograph or still image. This is an issue that warrants a more fully developed record by both parties. For now, even without having the benefit of Petitioner’s position on this issue, we determine that there is a reasonable likelihood that Petitioner would be successful in refuting Patent Owner’s proposed negative limitation. This is because the ’158 patent makes clear that the invention is intended to address “a need for a digital camera in which the effective single-frame dynamic exposure range is expanded” to accommodate situations wherein a scene may include “an indoor room with a window view of the outdoors, an outdoor scene with mixed shadows and bright sunshine, and evening or night scenes combining artificial lighting and shadows.” Ex. 1001, 1:43–49, 2:28–42, 3:39–41. The ’158 patent explains that “[i]mage capture by the camera is performed using multiple camera channels, and each camera channel is controlled during a frame under an independent integration time.” Id. at 3:47–50 (emphasis added). The ’158 patent states further that its “digital camera systems, through the use of multiple integration times, enable formation of an image having a wide dynamic range by combining the data from all camera channels to form a composite single frame.” Id. at 3:28–61 (emphasis added). Still further, the ’158 patent states for one exemplary embodiment that “[t]he integration time of at least one channel is controlled relative to the integration time of at least one other channel so that an image formed by combining data of a frame received simultaneously from the channels has a relatively large dynamic range.” Id. at 5:6–11 (emphasis added). Rather than supporting Patent Owner’s contention that the meaning of the term “integration time” excludes a photograph or still image, the above illustrative teachings from the ’158 patent establish at least a reasonable likelihood that Petitioner would succeed in establishing that “integration time,” and the term “scene” more particularly, encompasses the time the image sensor collects and integrates signals for a photograph or still image. As Patent Owner appears to acknowledge, the ordinary meaning of “scene” encompasses a “shot,” as well as, a “frame” (Prelim. Resp. 27 (citing Ex. 2011, 267–269)) and, as such, it would be counterintuitive to adopt an interpretation of “integration time” that excludes the very parts that make up a scene. Additionally, dependent claim 2 suggests that “integration time” encompasses a frame of a scene because it recites, “[t]he device of claim 1,” slip op. at 12

“demonstrated sufficiently that there is a reasonable likelihood it would be successful in establishing Matsushima discloses or renders obvious limitation 1.3. Petitioner’s evidence shows that Matsushima discloses “two independent imaging systems” controlled by CPU 30 that each form an image on the light-receiving surfaces of CCD sensors 18A and 18B via their respective imaging optics 14A and 14B. Ex. 1007 ¶¶ 17, 28 (emphasis added). In that configuration, Matsushima teaches that CCD sensors 18A and 18B each has an associated CCD drive circuit 20A and 20B that apply CCD drive pulses to retrieve the accumulated signal charges of their respective CCD sensors. Id. ¶ 23. Additionally, Matsushima teaches that CCD sensors 18A and 18B each has an “electronic shutter function that controls the accumulation time (shutter speed) of the charge accumulated by each sensor via shutter gate pulses” and that the shutter speed is determined based on integration of the Red, Green, and Blue signals in a single frame by the integration circuit 60A and 60B. Id. ¶¶ 24, 31, 34–35. Patent Owner notably does not dispute Petitioner’s cited evidence shows Matsushima discloses a processing component configured to control the integration time for CCD sensors 18A and 18B. See Prelim. Resp. 34– 50. Instead, despite Matsushima’s teaching that its imaging systems are independent, Patent Owner argues that Matsushima does not disclose independently controlling the integration time for CCD sensors 18A and 18B. Id. This is so, according to Patent Owner, because Matsushima describes operating CCD drive circuits 20A and 20B synchronously and describes using a single, common shutter speed for each of CCD sensors 18A and 18B. Id. at 35–38 (citing Ex. 1007 ¶¶ 17, 23, 27, 31, 34–35; Ex. 2005 ¶¶ 88–92). At this stage of the proceeding, Patent Owner’s argument raises genuine issues of disputed fact that would be best resolved on a fully developed record, rather than undermining the reasonable likelihood of success of Petitioner’s contention. In particular, going forward, the record would benefit from the parties addressing the issue raised by Patent Owner regarding whether Matsushima discloses to a skilled artisan individually controlling the shutter speed of each CCD sensor 18A and 18B. For example, although Patent Owner notes that Matsushima suggests an embodiment that may use a single, common shutter speed value and an intention for each circuit to be driven synchronously, it is unclear why those facts demonstrate Matsushima fails to suggest individually controlling the integration time of the disclosed independent imaging systems. To the extent Patent Owner is suggesting that limitation 1.3 does not encompass individually controlling the integration time of CCDs sensor 18A and 18B to operate synchronously with a single, common shutter speed value, Patent Owner should explain how the intrinsic record of the ’158 patent and the understanding of a skilled artisan at the time of the invention supports that position. Nevertheless, at this time and on this record, we determine there is a reasonable likelihood of success that Matsushima renders unpatentable claims 1, 2, 5, 8, 9, 11, 13–16, and 19.” slip op. at 21

“Petitioner asserts the term “lifter member” in the claims of the ’776 patent is “a means-plus-function term” because the claims “lack any ‘recital of structure, material, or acts in support thereof’ for the ‘lifter’ element.” Pet. 7 (citing 35 U.S.C. § 112(f)).

Patent Owner asserts that Petitioner: fails to comply with the requirement of 37 C.F.R. § 42.104(b)(3) to specifically identify the structure in the specification associated with that element. As ‘lifter’ is present in every challenged claim under all four grounds, Petitioner’s failure to provide a claim construction for ‘lifter’ is fatal to its Petition. Prelim. Resp. 13. We disagree. First, the claims in the ’776 patent do not use the single word “lifter” alone. The term used in some of the claims, see, e.g., independent claims 1 and 17, and the claims dependent from claims 1 or 17, is “lifter member.” We recognize that the written description in the ’776 patent states “the rotary-to-lifter 100 is also sometimes referred to herein as a ‘lifter member,’ or simply as a ‘lifter.’” Ex. 1001, 9:5–7. This suggests that that term “lifter” is intended to mean the “lifter member,” which makes the use of either term a distinction without a substantive difference. Moreover, neither independent claims 9 or 24, nor the claims dependent from claims 9 and 24, use the word “lifter” or “lifter member. Second, as stated in Petitioner’s Preliminary Reply, the Petition “identifies the portions of the specification that describe the corresponding structure for the ‘lifter’ when comparing its structure to that of the Lai prior art.” Prelim. Reply 1. The Petition provides a colored version of Figure 12 from the ’776 patent (reproduced below) and identifies the following corresponding structures from the Specification of the ’776 Patent: The “lifter member” of the ’776 patent includes a rotatable cam lifter 100 (yellow [ ]), with pin 104, 106, and 108 (green) on its face surface that engage protrusions 92 (blue) on the driver member 90 (orange). ’776 patent, 9:30–46, 16:34–48, Fig. 12.

That decision, however, construed claims in a related patent to “require two distinct structures: the main storage volume and a smaller “hollow cylinder” contained within the main storage volume. Based on the record before us, Petitioner’s proposed construction is consistent with the Federal Circuit’s construction, which states two structures can be distinct even if one distinct structure is “contained within” the other distinct structure. Although the parties dispute the construction of the “storage chamber” claim limitation, this dispute relates only to Grounds 2 and 4. See Prelim. Resp. 31. We need not resolve it to determine whether to institute review. The parties are welcome to develop their arguments regarding this claim limitation during trial. 3. Conclusion Regarding Claim Construction Our claim construction analyses in this decision to institute a trial do not preclude the parties from arguing their proposed constructions of the claims during trial. Indeed, the parties are hereby given notice that claim construction, in general, is an issue to be addressed at trial. Claim construction will be determined at the close of all the evidence and after any hearing. The parties are expected to assert all their claim construction arguments and evidence in the Petition, Patent Owner’s Response, Petitioner’s Reply, or otherwise during trial, as permitted by our rules.” slip op. at 19

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
