      “1. “closed loop” The term “closed loop” is recited in each independent claim. Petitioner asserts that in the Delaware action , the district court construed “closed loop” as “gas pathway within a display housing containing gas that is essentially isolated from external air.” Pet. 11 (citing Ex. 1026, 1). Petitioner asserts that the district court’s construction is the proper construction, in light of the specification and the prosecution history of the ’740 patent. Id. at 11–12. Petitioner explains: The ’740 patent refers to the gas/air, circulating through a closed loop as the circulating gas/air and also as the “isolated gas.” (Ex. 1001, 9:64–10:3, 10:7–9, 10:56–58, 11:30–12:6 (claims reciting circulating gas/air), 3:30–[39], 3:50–52 (specification referring to gas in the closed loop as “circulating gas” and “isolated gas”), FIG. 1.) Moreover, as noted above, the Applicant distinguished the claims from the Thielemans prior art based on the argument that the closed loop must be separate from and in addition to the open loop. (Ex. [1031], pp. 44-45, 160 (Responses filed on 01/07/2019 and 08/15/2019).) The Court’s “closed loop” construction should apply here, though Applicant notes that this claim construction does not affect the applicability of the prior art in this Petition because the art teaches the separate loops. Id. at 12. Petitioner’s characterization of the prosecution history with respect to the Thielemans reference is inaccurate. Our review of the cited portions of the prosecution history reveals that the Applicants did not argue to the Examiner that the closed loop and the open loop must be isolated from each other and cannot mix. Rather, the Applicants argued that Thielemans discloses having an open loop or a closed loop, not both an open loop and a closed loop. Ex. 1031, 44–45, 160. The Applicants also argued that Thielemans’s closed loop is not “about” and is not “encircling” the electronic image assembly. Id. at 160. The cited prosecution history does not support Petitioner’s assertion. Patent Owner explains that the ITC in the related investigation” slip op. at 16

      “appear nowhere outside of the claims in the ’595 patent. This fact alone tends to undermine Patent Owner’s suggestion that the “posterior surface” must be distinct from the “rear side.” In addition, Patent Owner’s cited portions of the Specification merely refer to the “posterior surface” as being the surface opposite that on which the LEDs are mounted to which heat from the LEDs is transferred. See Ex. 1001, 4:53–55, 4:57–60. They are inconclusive as to whether the “posterior surface” must be distinct from the “rear side.” Further, Mr. Gershowitz’s testimony in support of a “distinct” construction is based on his interpretation of the words “on the” in claim 4’s recited “posterior surface on the rear side of the PCB.” Ex. 2006 ¶ 128. Specifically, he testifies that “[i]f the posterior surface was the rear side of the PCB, the claim would have said so.” Id. He does not cite any support in the Specification of the ’595 patent for his interpretation. See id. Given that his testimony amounts to speculation divorced from the context of the Specification, Mr. Gershowitz’s testimony is entitled to little weight. We also have considered Mr. Smith-Gillespie’s testimony in support of Petitioner’s contention that an ordinarily skilled artisan “would have understood that the rear outermost surface of the PCB is the recited ‘posterior surface.’” Pet. Reply 20 (citing Pet. 83; Ex. 1002 ¶ 243). He cites a passage in the Specification of the ’595 patent that states: “The PCB may comprise a metal core PCB and the posterior surface of the PCB may be metallic so that air within the constricted convection channel may cool the metallic posterior surface (and subsequently the backlight assembly) more easily and efficiently.” Ex. 1002 ¶ 243 (emphasis omitted) (quoting Ex. 1001, 4:60–65). We accord Mr. Smith-Gillespie’s testimony more weight than Mr. Gershowitz’s testimony given that Mr. Smith-Gillespie’s testimony is rooted in disclosures about metal core PCBs in the ’595 patent.

      “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).

      “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

Patent Owner, however, provides an express construction for limitation [1.d] of independent claim 1 and the similar limitation of independent claim 13, namely limitation [13.c].

To resolve the controversy before us, we determine that these limitations require express construction. 1. “the glass element is configured to propagate and modify a stress wave to the coating/substrate interface to generate a tensile stress between the substrate and the coating” (limitation [1.d]) and “propagating and modifying a stress wave through the glass element to the coating/substrate interface to generate a tensile force between the substrate and the coating” (limitation [13.c]) Patent Owner argues these limitations mean “changing the profile of the laser generated compressive wave and propagating the wave profile as modified to the free surface of the coating, which upon reflection from the free surface as a tension wave generates a tensile stress at the coating/substrate interface.” PO Resp. 20 (citing Ex. 2011 ¶ 25).

      “a shock in the compression wave in the fused silica substrate. Even if we were to agree with Petitioner that Wang-Dissertation’s fused silica substrate modifies the compression waveform, we would not be persuaded that the fused silica substrate propagates the modified wave to the free surface of the coating, which upon reflection from the free surface as a tension wave generates a tensile stress at the coating/substrate interface, as limitation [1.d] requires. In view of the presence of tension-wave-1 in Wang-Dissertation’s experiments, we find Petitioner has not demonstrated persuasively that the fused silica substrate propagates a modified stress wave to the free surface of the coating to generate a tensile stress at the coating/substrate interface. Also, we find credible Dr. Gupta’s unrebutted testimony that any modified compression wave would attenuate in the substrate and not propagate to the free surface coating or generate a tensile stress at the coating/substrate interface. Ex. 2011 ¶¶ 93–98. Petitioner does not dispute that the experiments in Wang-Dissertation include tension-wave-1. See Ex. 1005, 65 (“The experimental picture is complicated somewhat by the presence of a tensile wave, reflected from the back of the confining layer.”). Nor does Petitioner dispute that Wang-Dissertation discloses that the tension-wave-1 propagates faster than the compression-wave-1 and eventually overtakes compression-wave-1. See id. at 65–66 (“Being tensile, it propagates faster that the peak compressive stress, and faster than the low stress tail of the main pulse. It eventually overtakes the compressive pulse and linear dissipative mechanisms govern the final thickness of the shock.”). Rather, Petitioner relies on Dr. Wang’s testimony regarding the timing of the waves through the sample and argues that tension-wave-1 does not overtake compression-wave-1 in the fused silica substrate. Pet. Reply 17 (citing Ex. 1038 ¶ 5). Dr. Wang testifies that the peak stress from tension-wave-1 is about 2 ns behind the peak of compression-wave-1 and will not reach the interface before the reflected tensile peak of compression-wave-1 reaches the interface in 0.3 ns. Ex. 1038 ¶ 5. However, as Dr. Gupta persuasively explains, the delay between tension-wave-1 and compression-wave-1 depends on the properties of the confining layer, and Wang-Dissertation acknowledges that these properties are not well controlled.

      “ordinary skill in the art (“POSA”) “would have had at least a bachelor’s degree, or equivalent, in electrical engineering, computer engineering, computer science, or a related field or an equivalent number of years of working experience, and one to two years of experience in networking environments, including at least some experience with live-streaming network architecture.” Pet. 16–17 (citing Ex. 1001 ¶¶ 78–82). Patent Owner contends that an ordinarily skilled artisan “would have [had] a bachelor’s degree in electrical engineering, computer engineering, computer science, or equivalent degree and, in addition, approximately two years of work experience with Internet video streaming, Internet communication, and related protocols.” Prelim. Resp. 20–21 (citing Ex. 2001 § IV.C). The differences between the parties’ definitions are minor, as recognized by Dr. Rubin (see Ex. 2001 ¶ 104), and we do not discern any meaningful differences based on the preliminary record. Accordingly, for purposes of this Decision, we adopt Patent Owner’s definition of the level of ordinary skill in the art. On the present record, we are satisfied that this definition of the level of skill is consistent with the teachings of the ’088 patent and the asserted prior art. Notwithstanding, we would reach the same determination under Petitioner’s formulation of the level of skill.” slip op. at 10

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundDecided for patent owner

      “obviousness contentions based on Ellis and Spivey rely expressly on the use of a “known webserver” to perform the “transmitting first instructions” limitations excerpted above. See Pet. 28–34. Yet Petitioner does not specify how such a webserver would be integrated with the other elements from Ellis and Spivey cited by Petitioner. At best, Petitioner provides a background section on the known use of webservers (see id. at 11 (citing Ex. 1001 ¶¶ 49–53, 127–134)), but this does not provide a rationale for integrating a webserver in the Ellis–Spivey combination. We also have considered Petitioner’s cited testimony from Dr. Wicker supporting this background section. The first cited portion, which is located at paragraphs 49–53 of Dr. Wicker’s declaration, supports the premises in the background section, but does not include a rationale for adding a webserver to the Ellis– Spivey combination. See Ex. 1001 ¶¶ 49–53. The second cited portion, which is located at paragraphs 127–134 of Dr. Wicker’s declaration, includes a rationale for modifying the Ellis–Spivey combination to include a webserver.3 See Ex. 1001 ¶¶ 127–134. But that rationale is completely 3 The cited rationale in Dr. Wicker’s declaration appears to be tailored to support Petitioner’s obviousness contentions in IPR2025-00251, where unaddressed in the Petition. We decline to assume that Petitioner adopts Dr. Wicker’s testimony about the rationale as its position, because that would amount to improper incorporation by reference under 37 C.F.R. § 42.6(a)(3).

      “c. Analysis We are not persuaded by Petitioner’s rationale for adding a facilitator- type webserver to the Ellis–Spivey combination based on “POSA’s Knowledge.” First, Petitioner’s combination of Spivey with Ellis is already allegedly based on improving latency issues via the incorporation of Spivey’s LDSD and MQSD in Ellis’s system. See Pet. 22–24. Petitioner touts that this modification would result in reduced latency to a time period “at least two orders of magnitude shorter than conventional time periods of legacy devices.” Id. at 23 (citing Ex. 1017 ¶ 96). But the Petition does not establish whether this latency improvement would or could be maintained when adding a separate webserver, as it has proposed. And Dr. Rubin testifies that the inclusion of an additional webserver—an additional component—is likely to create latency insofar as it must receive, process, and/or handle data. Ex. 2001 ¶ 305. We are persuaded by Dr. Rubin’s testimony, and we find that adding a webserver to Petitioner’s existing Ellis– Spivey combination tends to undermine Petitioner’s foundational rationale for combining these references, which is the reduction of latency. See Pet. 23.” slip op. at 22

      “Third, we agree with Patent Owner (Prelim. Resp. 49) that Petitioner does not explain sufficiently why an ordinarily skilled artisan would have added a facilitator-type webserver to the Ellis–Spivey combination when neither reference teaches or suggests a webserver for facilitating communication between a client and a socket server. Dr. Wicker’s supporting testimony stresses that “webservers were well-known components in streaming systems that were useful for facilitating communication between client devices and socket servers, and client devices and media sources.” Ex. 1001 ¶¶ 128–132. But “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 fails to provide any persuasive reason with a rational underpinning why an ordinarily skilled artisan would have been motivated to add a webserver to the existing Ellis–Spivey combination.” slip op. at 24

      “Petitioner contends that all claim terms should be given their plain and ordinary meaning. Pet. 8. Petitioner also argues that an ordinarily skilled artisan would have known that a “socket” is “a uniquely addressable communication endpoint on a server where first event information is provided to a VCD [viewer client device].” Id. at 34 (citing Ex. 1001 ¶ 163). Thus, Petitioner argues that a “first event socket corresponding to the first event information” is “a socket where information about one sporting event is provided to VCDs.” Id. Patent Owner states that “[e]xcept for the ‘socket’ term for which Patent Owner applies Petitioner’s construction . . . for purposes of [its] preliminary response, Patent Owner agrees that no terms require construction and construes all other terms consistent with their plain and ordinary meaning.” Prelim.
