      “generally known in the art, and that this is acknowledged by the ’853 patent. Pet. 40–41 (citing, e.g., Ex. 1001, 15:40–44). Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks. In either event, Petitioner has not sufficiently established that the proposed combination satisfies the “fractal includes a representation of the object based on landmarks” limitation of claim 1.” slip op. at 11

      “We agree with Patent Owner that the “master timecode generator” produces a signal that “controls” another timecode generator. See Prelim. Resp. 19 (citing a dictionary definition of “master” as “[one] that has control over another or others,” Ex. 2019, 3). We see no basis, however, to limit the claim term to a particular type of control. Patent Owner points to Figure 6 of the ’444 patent where “the master timecode generator creates master timecodes that are used to control the speed of the local timecode generator to ensure the two timecode generators are synchronized.” See Prelim. Resp. 19‒20 (citing Ex. 1001, col. 17, ll. 9‒16, Fig. 6). But Figure 6 merely depicts an exemplary “process for recording audio and for replaying and re-recording segments of missed audio in accordance with one embodiment of the present invention.” See Ex. 1001, col. 3, ll. 15‒17. Further, the Specification describes the exemplary embodiment of Figure 6 as a master unit providing master timecodes to a local audio device, which “synchronizes (e.g., jam syncs) its respective on board local timecode generator with the master timecodes,” but does not specify exactly how the master unit exercises control. Id. at col. 17, ll. 9‒17. Thus, we do not include any particular control mechanism (e.g., changing the speed of the local timecode generator) in our interpretation at this time. Based on the record presented, we interpret “master timecode generator” as “a producer of a master time reference signal that controls at least one other timecode generator” and “master timecode” as “a time reference signal used to synchronize at least one device.”” slip op. at 12

      “We agree with Patent Owner that Petitioner has not sufficiently shown that Strub teaches or suggests limitation 1[A]. Petitioner relies on Strub’s disclosure of a “master” recording unit as the claimed “remote receiver.” Pet. 34 (citing Ex. 1003, col. 38, ll. 29‒39). The cited portion of Strub is reproduced below: Data other than recording data can also be exchanged between recording units. For example, it may be desirable to coordinate the recordings obtained by recording units so that frames of visual recording data obtained by different recording units are temporally synchronized (e.g., so that a frame begins at the same time for each recording unit). This can be done by transmitting a synchronization pulse from a “master” recording unit to each of the other recording units (“slave” recording units). (Synchronizing analog visual data acquisition devices in this way is referred to as “genlocking.”) Ex. 1003, col. 38, ll. 29‒39. As argued by Patent Owner (see Prelim. Resp. 36), the cited procedure involves synchronizing frames of visual recording data, not audio recording data. Petitioner has not disputed Patent Owner’s assertions that the described “genlocking” technique is a video synchronization technique that does not apply to or affect the synchronization of system clocks or audio timestamps and has no bearing on audio synchronization. Nor does Petitioner explain in the Petition or the Preliminary Reply how or why an ordinarily skilled artisan would have applied this teaching to audio data recorded by an audio device. Petitioner cites this visual recording data synchronization passage as a solution to a problem that Strub identifies in clocks not being adequately synchronized to enable use of time-stamps associated with recordings to be used to synchronize the recordings. See Prelim. Reply 1‒2 (citing Ex. 1003, col. 38, ll. 29‒37, col. 79, l. 63‒col. 80, l. 2). However, immediately following the cited portion that identifies this problem, Strub further explains that “[i]f recording units according to the invention each include a GPS receiver, such mis-synchronization will only exist to an appreciable degree if one or more recording units are shielded from a GPS transmitter system for an extended period of time, e.g., several hours.” Ex. 1003, col. 80, ll. 2–27. Thus, Strub suggests that the solution to this problem is for the recording units to receive their timecodes not from a master recording unit, as argued by Petitioner, but from a GPS satellite.4 Petitioner does not address this teaching.” slip op. at 22

      “We agree with Patent Owner that the Petition does not rely on Woo as teaching or suggesting limitation 1[A]; Petitioner relies solely on the teachings of Strub. See Pet. 33–35 (arguing that “Strub teaches this element”). Petitioner references Strub’s teachings as being “consistent with and reinforced by the Woo reference” in the Preliminary Reply (Prelim. Reply 2), but this is not sufficient to rely on Woo, alone or in combination with Strub, as teaching this limitation. We also agree that the Lectrosonics IPRs’ findings regarding Woo teaching the “master timecode generator” limitation recited in those challenged claims are inapplicable here, where claim 1 recites additional limitations not present in those challenged claims. Compare Ex. 1001, col. 43, ll. 26‒27 (claim 1 of the ’444 patent: “a remote receiver, the remote receiver configured to create at least one master timecode and to receive audio data”) with Ex. 1028, col. 23, ll. 20‒21 (claim 1 of the ’814 patent: “at least one master timecode generator for generating a plurality of master timecodes”) and Ex. 1030, col. 23, ll. 38‒39 (claim 1 of the ’902 patent: “at least one master timecode generator for generating a plurality of master timecodes”). Based on the record before us, Petitioner has not shown sufficiently that Strub teaches or suggests “a remote receiver, the remote receiver configured to create at least one master timecode and to receive audio data,” as recited in claim 1. Accordingly, Petitioner has not shown a reasonable likelihood of prevailing on its assertion that claim 1 is unpatentable over Strub and Woo.” slip op. at 26

      “Regarding the alleged anticipation by Okaya, Petitioner has not adequately shown that Okaya discloses that the audio and video outputs of carousel 10 connect to a communication network without the intervening use of a computer or video conferencing system to which the carousel is connected. Okaya specifically describes that “the multimedia carousel 10 includes several input and output terminals for integrating with a multimedia computer or video conferencing system.” Ex. 1006, 3:1–4.

      “For reasons discussed below, we find Petitioner’s reasoning to be insufficient for one of ordinary skill in the art to add two cameras to Nagasawa’s case body 1, one on each side of case body 1. Petitioner does not adequately address the issue of sufficient spacing on Nagasawa’s case body 1, which includes two back-to-back mounted displays 4 and 8 (Figure 1A), to include two additional cameras, one facing inward and the other facing outward, particularly as one side of case body 1 is used for gaming (Fig. 1B, Ex. 1007, 3:53–65). In Nagasawa’s fifth embodiment, which includes a camera for video conferencing, the camera is placed in the hinge connecting case bodies 1 and 2, and not within case body 1. That is an indication that there is not enough room in Nagasawa’s case body 1 to incorporate a camera, much less two cameras as Petitioner has proposed to meet limitations [18c] and [18d]. Nagasawa’s Figure 12B is reproduced below: Figure 12B is a front view of a fifth embodiment of Nagasawa’s foldable phone in the unfolded position. Ex. 1007, 3:24–26. Nagasawa describes: “Video conference display may be provided where the photo sticker 51 is to be affixed in order to provide folding portable apparatus equipped with a small-sized TV camera 53 at the hinge.” Id. at 7:36–39. Nagasawa’s design already dictates where a camera would be mounted, and omits discussion of any other locations of that camera, much less a placement of it on the phone case body.

      “Additionally, Dr. Theogarajan testifies: “A person using [Nagasawa’s] pocket game would cover any camera placed on the outer surface of the first case body. Any camera placed in such a position would be abused with dirt and oil from a game player’s hand.” Ex. 2001 ¶ 145. We credit the testimony. It further undermines Petitioner’s proposed addition of two cameras to Nagasawa’s case body 1. Also, Nagasawa’s fifth embodiment already includes a video conferencing camera facing the user, mounted in the hinge connecting case bodies 1 and 2. In light of that teaching, there is little reason to add a camera to the inward facing side of Nagasawa’s case body 1.” slip op. at 24

While we do not make a determination regarding whether the Petition shows that there is a reasonable likelihood of prevailing were we to institute, for the reasons given, we determine that this Petition does not present particularly strong merits.

We take “a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv at 6. Because of the Sotera stipulation, factor 4 weighs strongly in favor of not exercising discretion. However, two other factors weigh in favor of exercising discretion, especially the trial date factor. The merits of Petitioner’s challenge are not particularly strong. A balanced assessment of the factors leads us to exercise discretion to deny the Petition. Therefore, we conclude that the evidence of record favors exercising our discretion under 35 U.S.C. § 314(a) to deny institution of an inter partes review.” slip op. at 22

      “partes review “allays concerns about inefficiency and duplication of efforts,” and strongly weighs against exercising our authority to deny institution. Fintiv, Paper 11 at 6. Of the three district court proceedings, the Lenovo Group case, pending in the Eastern District of Texas, is the most significant to our analysis here. In the Lenovo Group case, Lenovo Group has not requested a stay. Prelim. Resp. 16. Patent Owner argues that the Lenovo Group case is not likely to be stayed based on that court’s low grant rate in other cases and the progress of that case in particular. Id. at 17. The district court in the HP case denied a stay without prejudice and stated that a stay could be reconsidered in the future depending on the outcome at the PTAB. Prelim. Reply 3. The Dell case has been stayed. Id. On this record, we decline to speculate as to how any of the involved district courts where no stay is pending might rule on any future motion to stay. Thus, we determine that, while one stay has been granted, the lack of a stay in the other underlying district court cases, especially the Lenovo Group case, is not sufficiently persuasive to weigh this factor against exercising discretion. Apple Inc. v. Fintiv, Inc., IPR2020-00019, Paper 15 at 12 (PTAB May 13, 2020) (informative), cautions against speculating whether the district court would grant a stay if one were requested. Therefore, this factor has a neutral effect on the overall balancing of the Fintiv factors. B. Proximity of Trial Date to Projected Statutory Deadline (Factor 2) The scheduled trial date for the Lenovo Group case is November 3, 2025, which is about six months prior to the expected date for the final written decision here (i.e., late April 2026). See Prelim. Resp. 20; IPR2024- 01429, Ex. 2002 (Lenovo Group case Docket Control Order), 1. Petitioner argues this trial date is uncertain. Prelim. Reply 3. Further, Petitioner focuses its argument on what it terms a “growing backlog” in the Eastern District of Texas and “associated scheduling uncertainty.” Id. at 4. Petitioner refers to the status of the HP case, which is currently set for trial on September 21, 2026, and the stay in the Dell case. Id. Patent Owner responds that “[b]oth the scheduled trial date and the date of trial [in the Lenovo Group case] based on median time-to-trial statistics occur months before a final written decision would be expected here.” Prelim. Sur-reply 4. Patent Owner asserts that the time-to-trial statistics for the Eastern District of Texas project a median time-to-trial of 21.9 months. Prelim. Resp. 20–21 (citing Ex. 2007, U.S. District Courts Federal Court Management Statistics–Profiles—September 30, 2024). This projection yields a trial date that is prior to the expected final written decision date of April 2026. Prelim. Sur-reply 4. As with the previous factor, the status of the Lenovo Group case is our focus here. As stated, that trial is set to occur about six months before a final written decision would issue in this proceeding. The district court has stated that this trial date setting “cannot be changed without an acceptable showing of good cause.” Prelim. Resp. 20. We are not persuaded by Petitioner’s unsupported argument that the trial date is uncertain. We also consider the fact that the median time-to-trial statistic discussed by both parties projects a trial date earlier than the actual date set by the district court. Ex. 2007; Prelim. Sur-reply 1.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “E. Conclusion Regarding the Merits Petitioner does not present particularly strong merits. Petitioner’s arguments on the “bus limitation,” to succeed at trial, would require addressing a claim construction issue that was never addressed in the Petition and is arguably contradicted by the ’520 patent, which discloses transmitting packets representing a plurality of different control signals on a single bus. See Prelim. Sur-reply 2 (citing Ex. 1001, 7:34–38, 9:23–25, 9:50–54). Similarly, prevailing on the “modified protocol” issue would require proving that the HDMI–C protocol, which uses the same separate channel arrangement for CEC and DDC as standard HDMI, is sufficiently “modified” to meet the claim. Taking into account Patent Owner’s persuasive arguments supra in response, and for the reasons given, we do not find the merits of Petitioner’s position on either of these dispositive issues to be particularly strong.” slip op. at 20

      “example, claim 11 recites “receiving a synchronization symbol by a receiver indicating a packet type, each packet type having a different synchronization symbol.” Ex. 1001, 37:53–55. The other independent claims challenged in the Petition are similar in their recitation of a “synchronization symbol.” See id. at 37:9 (claim 1), 38:26–27 (claim 19). Petitioner argues this limitation is disclosed by Auld in view of MPEG-2 Part. 1. Pet. 15–16. Citing Figure 5 of Auld, reproduced in Section IV.C.1, supra, Petitioner asserts that “[t]he ‘sync codes’ in Auld consist of sequences of symbols that are used for synchronization, and therefore qualify as synchronization symbols.” Id. at 17. Patent Owner responds that “what the Petitioners identified as a ‘synchronization symbol’ [in Auld] is in what they have identified as a ‘packet of (or having) symbols.’” Prelim. Resp. 1. In contrast, “[i]n the specification and claims of the ’798 Patent, the claimed ‘synchronization symbol’ is separate from, and precedes, the claimed ‘packet of (or having) symbols.’” Prelim. Resp. 1. In disputing Petitioner’s identification in Auld of a synchronization symbol as claimed, Patent Owner points to Figure 9A of the ’798 patent (reproduced in Section II.C, supra), showing synchronization primitives 901 and 905 as separate from and transmitted before packets 902 and 907, respectively. Id. at 4. Patent Owner also relies on the description of the Figure 9A embodiment in the ’798 patent specification. Id. at 3–5. That description places transmission of the synchronization primitive encoded with the patent type before the control packet in the transmission sequence:” slip op. at 18

      “is our focus here. As stated, that trial is set to occur about six months before a final written decision would issue in this proceeding. The District Court has stated that this trial date setting “cannot be changed without an acceptable showing of good cause.” Prelim. Resp. 17. We are not persuaded by Petitioner’s unsupported argument that the trial date is speculative. We also consider the fact that the median time-to-trial statistic projects a trial date of July 2025, earlier than the actual date set by the District Court. Ex. 2002; Ex. 2008; Prelim. Resp. 17–18. The fact that the time-to-trial statistic is earlier than the trial date set by Judge Gilstrap confirms that the schedule set by the District Court is credible and should be given weight. From this evidence, we are persuaded that we should rely on the trial date in the Lenovo Group litigation as the main indicator of a trial court reaching the merits of the invalidity of the patent-at-issue before we issue a final written decision.

      “integrity of the system are best served by denying or instituting review” when evaluating these factors. Fintiv at 6. Because of the Sotera stipulation, factor 4 weighs strongly in favor of not exercising discretion. However, two other factors weigh in favor of exercising discretion, especially the trial date factor. The merits of Petitioner’s challenge are not particularly strong. A balanced assessment of the factors leads us to exercise discretion to deny the Petition. Therefore, we conclude that the evidence of record favors exercising our discretion under 35 U.S.C. § 314(a) to deny institution of an inter partes review challenging claims 1, 2, 6, 7, 23, 25, 31, 53, 68, 70–72, 74, and 75.

      “The parties each raise facially valid points based on the claim language. Petitioner has the burden to show “[h]ow the challenged claim is to be construed.” 37 C.F.R. § 42.104 b(3). Petitioner does not explain how, under its broad construction, the decoder “decodes the encoded data to recover application and control bits in accordance with a line code.” That is, if the encoding does not encode both “application and control bits,” then how can decoding “recover” both under Petitioner’s claim construction? It is not clear on this preliminary record whether the specification supports Petitioner’s broad claim construction. For this reason, Petitioner’s showing based upon the broad claim construction outlined above is not “particularly strong.” See Fintiv at 14–15. As discussed further below, Petitioner also presents a showing under Patent Owner’s more narrow construction. 3.” slip op. at 15

      “Finally, Petitioner argues obviousness over each of Banes and Calvignac. These assertions of obviousness rely on testimony on the understanding of a person of ordinary skill in the art of the “spare” code and flags as “out-of-band symbols.” Pet. 20−21. Petitioner also argues that it was “well-known” to include in-band symbols in data packets and to include out-of-band symbols in control indicators to obtain the benefit of allowing data payload information to be readily distinguished from control information. Pet. 63−64. The testimony cited in support relies on the disclosure of Shin ’464 for this statement.5 Ex. 1003 ¶ 225. The exact same disclosure of an 8-bit encoding technique that uses in-band and out-of-band symbols within a transmission is found in another Shin patent that is incorporated by reference in the ’905 patent and has overlapping inventors. Ex. 1006, 9:60−10:8, Ex. 1008, 5:15−28, Ex. 1001, 24:50−55. In other words, the alleged benefit may be better characterized as part of the inventor team’s work rather than a technique “well-known” in the art. And for this reason, Petitioner’s obviousness contentions are less persuasive. 5 U.S. Patent No. 5,974,464, filed September 30, 1996. (Ex. 1006, “Shin ’464”).” slip op. at 15
