    “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).

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

    “specification is the ‘single best guide to the meaning of a disputed term,’ . . . and ‘is, thus, the primary basis for construing the claims.’” Trs. of Columbia Univ. in City of New York v. Symantec Corp., 811 F.3d 1359, 1362 (Fed. Cir. 2016) (citations omitted). Although Patent Owner contends that the Specification disparages systems that impose significant restrictions on the possible choices of frequencies (PO Resp. 21), we find availing Petitioner’s contention that “[s]upport for Patent Owner’s construction is absent from the specification.” Pet. Reply 10. As Petitioner points out, Patent Owner’s claim construction “appears to be based on a single paragraph of the ’443 patent referring to preexisting ‘synchronization schemes [that] restrict the phase relationship and relative frequencies of the clocks.” Id. That is, the only reference by Patent Owner to the Specification is that the Specification states that “Some synchronization schemes restrict the . . . relative frequencies of the clocks, thereby eliminating the need for hardware arbitration [27]. Unfortunately, these schemes impose significant restrictions on the possible choices of frequences.” PO Resp. 26 (citing Ex. 1001, 6:32–36). We agree with Petitioner that such disclosure in the Specification “does not describe how these synchronization schemes ‘restrict the phase relationship and relative frequencies’ with any specificity.’” Pet. the Specification that some schemes impose restrictions on the possible choices of frequency is not a disparagement of any system that has limited choices of frequency or would preclude the claims from covering such prior art techniques. Instead, as Petitioner points out, the Specification of the ’443 patent states “[t]he preferred embodiment uses four domains […] so that domains may vary somewhat in size and still be covered by a single clock.” Id. (citing Ex. 1001, 5:57–59). As Dr. Baker testified in support of Petitioner’s contention, “the preferred embodiment of the ’443 patent relies on a single external master clock that distributes a signal to the local PLL of each domain.” See Ex. 1032 ¶ 9. Thus, although Patent Owner contends that clock signals generated based on a master clock cannot be interpreted to be generated independently of the clock signals generated for others of the plurality of domains (PO Resp. 49), we agree with Petitioner that such claim construction would “exclude[] the preferred embodiment of the ’443 patent,” which is disfavored. Pet. Reply 11. For the reasons discussed above, we conclude that “changeable independently” of the other domains does not require that the separate clocks in the plurality of domains be globally-asynchronous.” slip op. at 12

We find the testimony of Dr. Baker insufficient to support Petitioner’s position. Ex. 1002 ¶¶ 53–56, 213, 215–219.

Without evidentiary support, we are left with speculation and impermissible hindsight. See in Re Wagner, 379 F.2d 1011, 1017 (CCPA 1967). We decline to engage in speculation.

Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing PO Resp. 47–48 (citing Ex. 2022, 27:5–10, 27:21–28:1; Ex. 2021 ¶ 96)).

So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don’t know that the real world is necessarily cut and dry.

Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2021 ¶¶ 82–88.

    “We agree with Patent Owner. Petitioner’s argument appears to be purely hindsight analysis based on the teachings of the ’659 patent and the limitations of challenged claim 6 because there is insufficient evidence or teachings in the cited prior art to suggest the sharing of virtual keys. Petitioner’s argument that having “rental microbusiness” implemented as a “smart phone application” that enables sharing virtual keys is insufficient to show obviousness, because, as noted by Patent Owner, certain embodiments in Kleve appear to discourage or even hinder the sharing of virtual keys. These embodiments require the use of credentials associated with the virtual key, where the credentials can be “facial recognition, voice print recognition, matrix barcode (ex. two-dimensional code), code word or phrase for speech recognition, temporary mobile web login IDs and password, or other types service.” See Ex. 1005 ¶ 37. Dr. Almeroth testifies that multiple people could be authorized on the same vehicle if they collectively rent a vehicle and that a person of ordinary skill in the art would “have been motivated to enable each user to share the virtual key with other authorized users associated with the same rental request.” Ex. 1004 ¶ 55. But given Kleve’s disclosure that the system handles key generation and distribution (Ex. 1005 ¶ 39), the evidence does not show that a person of ordinary skill in the art would have wanted to give this control to each authorized user who has received an e-key. “It is impermissible to use the claimed invention as an instruction manual or ‘template’ to piece together the teachings of the prior art so that the claimed invention is rendered obvious.” Fritch, 972 F.2d 1260, 1266 (Fed.

    “connections or multiple, parallel/simultaneous TCP connections are critical, unclaimed features of the ’564 patent. Indeed, Petitioner does not argue as much, and claims 2, 9, and 11 all at least recite multiple TCP connections. Notwithstanding, I would reach the same conclusion as my colleagues that Patent Owner is not entitled to a presumption of nexus. I am persuaded by Petitioner’s argument (Pet. Reply 22–23) that Patent Owner cannot credibly maintain that it is entitled to a presumption of nexus to the same products— the MOVE Media Player and “Sling TV”—across nine patents and 120 claims having different scope while citing to substantially the same alleged evidence of secondary considerations. The MOVE Media Player and “Sling TV” cannot be coextensive with the challenged claims here under these circumstances. In addition, Patent Owner’s own cited evidence suggests that MOVE’s plug-in is a “key” feature of its technology, particularly to ensure “fluidity of playback” (PO Resp. 50 (quoting Ex. 2048) (emphasis omitted)), but the claims do not recite a plug-in. This also undermines Patent Owner’s assertions of coextensiveness for claims that all recite “continuous playback.” Otherwise, I agree with my colleagues’ finding that Patent Owner has not adduced significant evidence of direct nexus. Accordingly, I join in my colleagues’ finding that Patent Owner has failed to establish a nexus between the asserted evidence of secondary considerations and the challenged claims. I also agree that Patent Owner’s evidence of secondary considerations is entitled to insignificant weight, or little to no weight, and that it does not outweigh Petitioner’s persuasive obviousness showing under the other Graham factors.

    “1. “continuous playback” This term appears in independent claims 1 and 13. 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). According to Petitioner, “shifting quality ‘to achieve continuous playback’ is aspirational, not limiting, language.” Id. (citing Bristol-Myers Squibb Co. v. Ben Venue Labs., 246 F.3d 1368 (Fed.

  • Skill levelSkill level board ownDecided for petitioner

    “B. Level of Ordinary Skill in the Art Petitioner proposes that the level of ordinary skill in the art is an artisan with a working knowledge of POS activation systems and lottery systems that was gained through a mixture of training and work experience in the relevant field such as (i) having a Bachelor’s degree in computer science, computer communications, electrical engineering, or equivalent degree, coupled with at least three years of work experience; (ii) having a Master’s degree in computer science, computer communications, or electrical engineering, but having less work experience; or (iii) having no formal degree, but having experience in the relevant field of at least six years of work experience. Pet. 2–3 (citing Ex. 1003 ¶¶ 13–14).9 Patent Owner states that, “[f]or the purpose of this proceeding, Patent Owner adopts the Petition’s proposed definition of the level of ordinary skill in the art.” PO Resp. 19 (citing Pet. 2–3). We find that the parties’ agreed-upon level of ordinary skill in the art is consistent with the level of ordinary skill in the art reflected by the ’451 patent and the prior art of record. See Inst. Dec. 14; see Okajima v. 9 Petitioner proposes the same level of ordinary skill in the art that the Board adopted in PGR2020-00084 (Pet. 2–3 (citing Ex. 1008, 11)), and IPR2023- 01235 (see IPR2023-01235, Paper 34 at 12–13).

    “On balance, we find that even with the alleged disadvantages identified by Patent Owner, one of ordinary skill in the art would have been motivated to modify Szrek with Llach’s third-party transaction processor because the advantage of having a “centralized intermediary” allows Szrek’s system to support different game providers, such as different lottery companies, which would reduce some implementation costs and allow the system to be more easily and cheaply extended. Pet. 47 (citing Ex. 1003 ¶ 181); see Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine”) (citing Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000)); see also Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 795 (Fed. Cir. 2021) (stating the same). We acknowledge that the combination comes with some disadvantages, including “add[ed] delay, reduce[d] efficiency, and . . . implementation complexities by converting a simple, direct communication exchange into an exchange that traverses multiple systems.” PO Resp. 52 (citing Ex. 2052 ¶ 163). But, “[t]he fact that the motivating benefit comes at the expense of another benefit, however, should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.” Winner, 202 F.3d at 1349 n.8. Here, Szrek expressly teaches indirect communication as a possible implementation of its system and Petitioner’s combination—employing Llach’s third-party transaction processor as part of the indirect communication channel—offers the attractive benefit of allowing Szrek’s system to support different game providers, which would reduce some implementation costs even if it might increase other costs, e.g., by having to program certain components (e.g., the cash registers) differently. Specifically, we find that the ability to expand Szrek’s system to support different game providers provides advantages that outweigh the disadvantages discussed above in the circumstance where one desires a more robust and comprehensive system. See Pet. Reply 23 (noting three advantages of the combination— (1) “allow[ing] Szrek’s system to use ‘a centralized system for activating lottery tickets from different retailers and different locations,’” (2) “allow[ing] support for different game providers, such as different lottery companies,” “reduc[ing] implementation costs,” and (3) “allow[ing] Szrek’s system to ‘communicate with individual card” slip op. at 37

    “This disclosure is inconsistent with any suggestion that the Fangman system, when routing a telephone call to its destination, identifies the private IP address of the destination telephone by determining the port range to which the port number of the destination telephone belongs. When Fangman describes the NAPPT process, it does not indicate that port ranges are used, but rather repeatedly states that port numbers are used: The [service gateway] receives a data packet from the IP device, including a public destination IP address . . . a destination port number . . . and source information, NAPPTs the data packet, using the [public destination IP address] and the [destination port number] to identify the [IP telephone] . . . .
