      “We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses element [1.2] because the evidence cited does not disclose a “first computer system being configured to provide remote control of the first pump or first valve” (i.e., a fluid-handling device). Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but Petitioner has not identified any disclosure of the capability to remotely control fluid-handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, Kahn’s disclosures that Petitioner relies on for allegedly teaching remote control are deficient. We discuss each. First, Petitioner points to the following, “[f]or instance, as illustrated in FIG. 1C, a fluid control device such as a valve 15A is located on the input side of a sen[s]or unit 110.” Ex. 1005, 8:19–21, cited in Pet. 13. This portion of Kahn, however, does not disclose remote control. Second, Petitioner cites to the following: Finally, or in addition to, the communication unit 112B can include on-site alerts such as optical (indicator lights), audible alerts (e.g., alarm sounds), tactile (e.g., vibration of the unit) or can be interfaced to an appropriate control valve for simply shutting off the supply of fluid upon the detection of emergency events, for instance.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “target value” is part of a command that is sent from a computing device to a server and then to a controller. The controller then receives a measurement of the fluid by a sensor and determines whether the measurement satisfies the “target value.” If the measurement does not satisfy the “target value,” further operations are undertaken. The recited operation sequence makes clear that the plain and ordinary meaning of “target value” is not as Dr. Wooley opines because the particular operating condition that a device is in at a particular time is represented by the measurement taken by the sensor, 11 Some claim language less relevant to construing “target value” was omitted for ease of reference. which the controller then uses to determine whether the measurement satisfies the “target value.” Additionally, claim 1 recites that the “target value” is sent as part of a command to the controller. The “target value” is not sent to the controller from the sensor, as might be expected if the plain and ordinary meaning of “target value” were as Dr. Wooley opines. Petitioner and Dr. Wooley’s construction would also result in “target value” meaning effectively the same thing as the measurement of the fluid by the sensor, a concept that is separately recited in claim 1 and to which the “target value” is compared. The Specification of the ’680 patent does not support Petitioner’s understanding of the plain and ordinary meaning of “target value.” Although the Specification does not recite “target value,” it recites “target state,” and describes “target state” sufficiently to understand the plain and ordinary meaning of “target” as used in “target value” and “target state.” In particular, the ’680 patent explains that “[i]n some embodiments, the process 104 includes receiving, via a network interface, from a remote user device, (e.g., via a command-center server) a command to change a state of a fluid-handling device to a target state.” Ex. 1001, 11:48–51. This portion reflects that the command is seeking to change a state of a fluid-handling device to a target state. In other words, the “target value” or “target state” is not generally “the particular operating condition that a device is in at a particular time”; rather, it is a value or state that the fluid-handling device is desired to be in, as Patent Owner and Dr. Durham explain. Additionally, just as claim 1 recites a directional component for the “target value” to be sent to the controller in a command, so too does the Specification describe a “target state” as being sent in a command from a remote user device. Thus, the Specification clearly supports the plain and ordinary meaning proposed by Patent Owner and Dr. Durham and not the plain and ordinary meaning proposed by Petitioner and Dr. Wooley. slip op. at 14

      “time-stamped process data, report exception therein to the remote host, and extract and transmit time-stamped process data to the remote host.” Ex. 1005, Abst. (emphases added). Almadi explains that its remote field systems must include a plurality of controller units “to issue commands to, and gather and process data from a plurality of field devices, including remote systems and instruments, . . . [and] a database server for the storage of process data retrieved from the remote subsystems and instruments.” Id. at 2:22–30 (emphases added). Based on these disclosures, we agree with Patent Owner that Petitioner has not established that Almadi discloses element [1.4]. Specifically, the teachings from Almadi identified by Petitioner refer to process data, which is data retrieved from the remote subsystems/field devices. Thus, we understand that Almadi’s teaching—of using an Ethernet switch to transmit “process data”—describes transmitting data from the remote subsystems/field devices. See Ex. 1005, 3:13–17, cited in Pet. 15. But claim 1 and particularly element [1.4], recites “sending, with the server, the target value to the network address [which identifies a controller of the fluid-handling device13] via the network,” which is different than sending process data from the field devices to the remote host or database server for storage.” slip op. at 19

We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient.

Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively.

      “distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony. Weighing this evidence all together, we find that Petitioner has failed to show that it is more likely than not that Tomioka’s teaches the claimed comminution under Petitioner’s first theory.” slip op. at 15

      “obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off. Thus, we find that Petitioner has failed to show that it is more likely than not that Tomioka accounts for the claimed “comminuting.”” slip op. at 15

      “For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

      “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.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “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

    • BurdenNot shown unpatentable

      “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
