      “We agree with Patent Owner that Petitioner’s contentions in this ground do not cure the issues for limitations 1D and 1E. Petitioner’s contentions in this ground involve combining Khan and Ali’s teachings of identifying a horizon line and lane lines with Choe. For example, Petitioner argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have combined known elements according to known methods to yield predictable results” and that “[i]mplementing these known mathematical models in Choe’s calibration system, according to their known functions, would have yielded predictable results.” Pet. 39. Petitioner further argues that “[u]sing predictive models for Choe’s lane and horizon prediction would have used a known technique (predictive models) to improve similar devices in the same way” and that “[u]sing predictive models for Choe’s lane and horizon prediction would have also applied a known technique (predictive models) to a known device (a manual annotator device) ready for improvement.” Pet. 40. Petitioner’s proposed combination, therefore, still relies on Choe’s teachings of transmitting an overlaid image to an annotator device. We note that Petitioner asserts that, “[o]nce Khan in view of Ali identifies the horizon and lane lines, it overlays the horizon line and/or lane lines on the video, as shown in the screenshots below.” Pet. 41–42. Although Petitioner mentions Khan and Ali’s teachings with respect to video here, Petitioner does not adequately explain how the teaching of an overlaid video would be combined with Choe’s single image annotator teachings. As discussed above, Choe discloses transmitting a single overlaid image to the annotator” slip op. at 23

      “Thus, Petitioner has not provided sufficient evidence and argument to explain how the additional teachings of Khan and Ali teach limitations 1D and 1E in combination with Choe. Petitioner, therefore, has not demonstrated unpatentability of claims 1–5 by a preponderance of the evidence. F. Obviousness over Choe and Workman (Claims 1–4) Petitioner asserts that claims 1–4 would have been obvious over the combined teachings of Choe and Workman. Pet. 47–52; Pet. Reply 26–30. Petitioner asserts that, “if [Patent Owner] alleges that Choe does not explicitly disclose which predictive models it uses or whether it uses predictive models to identify the horizon line, a [person of ordinary skill in the art] would have searched for references that use predictive models and how such models were used,” which “would have led to Workman, which discloses predictive models to identify the horizon line.” Pet. 47. According to Petitioner, “[u]sing Workman’s predictive model to identify the horizon line would also have merely been combining known elements ([convolutional neural networks (CNNs)] and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way.” Pet. 48–49. Thus, Petitioner relies on Workman to teach a predictive model to identify a horizon line. See Pet. 47–49. Choe with respect to limitations 1D and 1E. Indeed, Workman involves horizon line estimation in single images. See Ex. 1011, 10 (§ 5) (“We introduced Horizon Lines in the Wild (HLW), a new dataset for single image horizon line estimation, to address the limitations of existing horizon line detection datasets.”). Petitioner, therefore, has not demonstrated unpatentability of claims 1–4 by a preponderance of the evidence.” slip op. at 24

      “We do not agree with Patent Owner’s argument because it advocates for the importation of functional limitations from the ’794 Patent Specification into the claims––namely the disclosure that the bypass circuit continues to conduct electricity, and keeps the remaining lights lit, even when one or more individual lighting elements in the series are burned out, missing, or defective. See PO Resp. 7–9. It is well settled that it is improper to read an extraneous limitation into a claim from the specification. See e.g., Commark Comm’s Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998); E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1433 (Fed. Cir. 1988). An extraneous limitation is “a limitation read into a claim from the specification wholly apart from any need to interpret what the patentee meant by particular words or phrases in the claim.” E.I. du Pont de Nemours, 849 F.2d at 1433. Moreover, the language that Patent Owner wishes to import into the claim from the Specification is functional language that describes the function of the resistor bypass circuit. As explained below in the section addressing the subsequent claim recitation “conducting current at all times across the light sources when current is flowing through the circuit regardless of whether the LED light source are conducting current therethrough,” functional language is evaluated in view of the applied prior art to determine whether it imparts additional structure to distinguish the claimed invention over the prior art. Accordingly, to the extent the preamble recitation is limiting, we need not provide an express construction for “[a] resistor bypass circuit for a series lighting circuit.”” slip op. at 7

Patent Owner does not dispute Petitioner’s proposed definition of a person of ordinary skill in the art for the purpose of institution. See PO Resp. 2.

      “On this record, we determine that the recitation “to achieve continuous presentation” is limiting and requires an amount of continuous (uninterrupted) playback/presentation after an upshift or downshift. The specification describes agent controller 702 determining whether to upshift based on a trigger threshold Θup, which itself is based on various factors including a current read ahead margin and a minimum safety margin. See Ex. 1001, 17:44–58. If agent controller 702 can sustain upshift quality, then it will upshift and request higher quality streams. See id. at 17:58–61. Conversely, when an upshift is not possible, agent controller 702 determines whether to downshift based a different threshold Θdown, which itself is based on the same sort of factors. See id. at 18:4–7. When the stream quality is not adequate, it downshifts. See id. at 18:7–14. These disclosures are similar to the language of claim 12, which recites “repeatedly generating a factor indicative of a current ability to receive the digital content at a rate sufficient for presenting the digital content as the digital content is received, . . . wherein the factor relates to a performance of the network” and “making the successive determinations whether to change the requested bit rate based on the factor to achieve continuous presentation of the digital content using the individually-requestable portions of the highest bit rate one of the copies determined receivable at that time.” Ex. 1001, 20:5–16 (emphasis added). That is, claim 12 refers to “achiev[ing] continuous presentation” based on what is “sufficient for presenting the digital content,” trading quality to ensure continuous playback.” slip op. at 14

      “server comprises at least two servers and wherein at least one streamlet is requested from a first of the at least one server and at least one other streamlet is requested from a second server of the at least one server other than the first server.” Ex. 1001, 19:7–12. Petitioner references its mapping of the “at least one server” in claim 1 to Leaning’s server 1. Pet. 20 (citing Ex. 1004, 2:15–16, 2:18–22, 2:31–32, 5:8–14, Fig. 1), 23 (citing Ex. 1004, 6:13–26, 9:3–7, 16:6–12), 37; see supra §§ II.D.2.b–c. Petitioner contends that, “[t]o the extent Leaning does not disclose at least two servers wherein one sub-file (streamlet) is requested from a first server and another sub-file (streamlet) is requested from a second server such an arrangement would have been obvious in view of the knowledge of a [an ordinarily skilled artisan].” Id. at 37. Citing the common nature of such an arrangement, Petitioner contends that an ordinarily skilled artisan would have been motivated to provide multiple web servers containing the same sets of sub-files for streams in order to have redundancy in the system and allow for clients to establish connections with multiple servers and request a first sub-file from a first web server and, if the connection between the first web server becomes congested or the first web server otherwise fails or becomes unavailable, request a subsequent sub-file from the second web server. Id. at 37–38 (citing Ex. 1003 ¶ 85; Ex. 1012, 108,5 Fig. 4-11). Patent Owner does not dispute Petitioner’s analysis for claim 3. We are persuaded that it would have been obvious to implement Leaning’s server 1 as two servers that store different streamlets based on Dr. Houh’s uncontested testimony about system redundancy. See Ex. 1003 ¶ 85. His testimony is backed by a contemporaneous reference about HTTP that shows requests for different objects from different servers over parallel TCP connections. See, e.g., Ex. 1012, 108–09, Fig. 4-11. Thus, we determine that Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 3 would have been obvious over Leaning.” slip op. at 34

For example, limitation 1D of claim 1 recites “adapting the successive determinations to shift the playback quality based on the factor to achieve continuous playback of the video using the streamlets of the highest quality copy of the video that is determined to be sustainable at that time.” Claim 13 recites a similar limitation. Petitioner contends “[t]he claims’ plain language only requires that the shift in playback quality is made ‘to achieve continuous playback.’” Pet. Reply 1 (citing claim 1).

      “and digital selector 240 disclosed by Zhang is “digital circuitry,” which is configured to receive a plurality of frequencies comprising a plurality of desired/undesired television channels from ADC 220 and to output the desired television channels to demodulators 250 as a digital datastream. Tr. 71:14–17 (PO Counsel: “There is no dispute that in both Zhang and the patent, an RF signal that has both desired and undesired channel comes in and what’s sent to demodulators are desired channels. Nobody is disputing that.”), 134:3–5 (PO Counsel: “The issue is not whether the black box 230- plus-240 is the digital circuitry. It is. The issue is not whether or not that overall circuitry selects channels. At some level, it does.”). In other words, Zhang teaches digital circuitry that is (1) capable of receiving a plurality of frequencies including desired/undesired television channels and (2) capable of distinguishing between the desired/undesired channels to output the desired television channels to a demodulator. We find these uncontested facts to be highly probative of Petitioner’s contention that, to a skilled artisan, Zhang suggests that its digital circuitry is capable of selecting the desired television channels from a digitized plurality of frequencies that include both desired/undesired television channels. This is because Zhang’s digital circuitry is able to take what is input originally as a digitized plurality of frequencies having both desired/undesired television channels and, using those frequencies, pick out the desired television channels that are subsequently output to a demodulator. Zhang teaches that “because only the selected channels are later demodulated” the disclosed digital circuitry is “much faster than traditional analog channel switching through RF tuners” and it “dissipates less heat because fewer resources are required when demodulating only the selected RF channels.” Ex. 1013 ¶ 28 (emphasis added).” slip op. at 22

But Petitioner does not argue or suggest that “digital circuitry” should be construed as a means-plus-function term; nor does Petitioner make an argument to overcome the presumption that 35 U.S.C. § 112, paragraph 6, does not apply. See id. Patent Owner does not address claim construction. See generally PO Resp.

Patent Owner “does not contest Petitioner’s definition of a person of ordinary skill in the art, but it reserves the right to do so in the event that trial is instituted.” Prelim. Resp. 7.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

      “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

      “least in part on a second message including at least one command in a second format.’” Pet. 4 (citing Ex. 1104, 168–173). The cited portion of the prosecution history shows that the applicant distinguished its claims from the prior art based on different first and second formats. The applicant argued in particular, Applicant submits that [the prior art] is completely silent with regard to “receiving, from the remote server device, a first message that includes at least one command in a first format, wherein the first message is received based at least in part on a second message including at least one command in a second format having been sent from the associated remote computing device.” In fact, [the prior art] never describes commands in different formats. . . . Ex. 1104, 170. Based on the applicant’s argument in this regard, we find that the prosecution history limits the scope of claim 1 to different first and second formats. In other words, the applicant’s argument during prosecution distinguishing its claims from the prior art based on different first and second formats overcomes the presumption based on claim differentiation that claim 1 encompasses first and second formats that are the same. See Fenner Invs., Ltd. v. Cellco P’Ship, 778 F.3d 1320, 1327 (Fed. Cir. 2015) (“Although claim differentiation is a useful analytic tool, it cannot . . . relieve any claim of limitations imposed by the prosecution history.”). Accordingly, claim 1 is limited to different first and second formats.” slip op. at 10

      “argument and evidence. As discussed above in the claim construction section, the recited first and second formats are limited to different formats. See supra Part IV.A. To satisfy this aspect of limitation 1D under its theory, Petitioner needs to show that in Danciu the format of the control information sent from the remote control to the server is different from the format of the control information sent from the server to the controlled device. The cited disclosures in Danciu, however, do not teach or suggest that these formats are different. Nor does Petitioner explain adequately how Danciu’s disclosures teach or suggest the two formats are different. We recognize that the control information in Danciu may be “processed” or “repackaged,” as Petitioner asserts, but it is not clear that the control information is processed or repackaged such that the format of the control information sent from the remote control to the server and the format of the control information sent from the server to the controlled device are different. Petitioner does not rely on Mahajan to teach or suggest the recited first and second formats but relies on Mahajan instead as providing “implementation details for transmission of commands for controlling a client.” Pet. 27. Petitioner contends that its proposed combination of Danciu and Mahajan would have provided a system where “Danciu’s remote control would translate commands associated with a first type of media playing application to a generic format, transmit them to the controlled device, which would translate them to a command associated with a second type of media playing application for execution.” Id. at 31. In other words, the controlled device would receive the generic commands sent from the remote control and then translate the generic commands. It is not clear how the proposed combination in this way teaches or suggests the format of a command sent from the remote control to a server is different from the format of a command sent from the server to the controlled device.” slip op. at 17

      “Aldrey and Mahajan meets limitation 1D under Petitioner’s second theory. Petitioner only alleges that it would have been obvious to an ordinarily skilled artisan that Mahajan’s RTS Media Abstraction Module could operate at a server like Aldrey’s service provider network 103. Pet. 65. The Federal Circuit has explained that “obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). Petitioner does not adequately explain why an ordinarily skilled artisan would have considered locating Mahajan’s abstraction module at a server, even if the abstraction module could operate at the server. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[T]here must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”). We note Petitioner further argues that combining Mahajan and Aldrey would have provided a system where “Aldrey’s end terminal would translate commands associated with a first type of media playing application to a command associated with a second type of media playing application on a STB.” Pet. 66–67; see also id. at 66 (“Mahajan’s server-command teachings could be implemented on Aldrey’s end terminal remote control.”). Arguing that Aldrey’s end terminal would translate commands seems inconsistent with Petitioner’s earlier argument for locating Mahajan’s abstraction module (which translates commands) at Aldrey’s network service provider. See id. at 65–67. Moreover, it is not readily apparent how command translation by Aldrey’s end terminal––rather than Aldrey’s network service provider–– teaches or suggests the format of a command sent from the end terminal to the network service provider is different from the format of a command sent from the network service provider to the STB. Petitioner does not close these logical gaps.” slip op. at 23

As we noted in our Rehearing Decision, however, the Federal Circuit has explained that “[t]he prosecution history modifies the scope of a claim term if ‘the patentee distinguished that term from prior art on the basis of a particular embodiment, expressly disclaimed subject matter, or described a particular embodiment as important to the invention.” Reh’g Dec. 8 (quoting Sentry Protection Prods., Inc. v.
