      “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. Pet. 13 (citing Ex. 1005, 10:62–67). We agree with Patent Owner that this portion of Kahn teaches on-site alerts and local control of the fluid-handling device. See Prelim. Resp. 7. This portion of Kahn does not disclose remote control.” slip op. at 18

    • 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 do not agree that Zalewski is substantively identical to Willgert. As discussed below in Section IV.D.4.c), Zalewski disclosed an RFID transponder in a removable cover for a phone that was completely separate from the voice call components of the telephone itself. Ex. 2001, 7:63–8:3. Based on this, Applicant successfully distinguished Zalewski because the RFID transponder functionality, being contained in a removable cover, was completely independent of the phone device, and thus the claim requirement of a “communication device determining the mobile communication device is in an operational space” was not met. Ex. 1002, 94–95. On this basis, Applicant also argued that claim requirements of switching between a voice call state and an RFID transponder state were not met. Ex. 1008, 18, 91, 134–135, 155; Ex. 1002, 530. In contrast, Willgert discloses an RFID transponder that is integrated with a mobile telephone, and so it cannot be distinguished on the basis that was used for Zalewski. Ex. 1004 ¶ 32. Accordingly, we decline to exercise discretion to deny institution pursuant to 35 U.S.C. § 325(d).” slip op. at 9

That person would have at least a Bachelor’s degree in Electrical Engineering, with a background in radio frequency communications as well as approximately two years of experience working with or researching radio frequency communication systems. Ex. 1003 ¶ 20. Patent Owner does not offer a specific definition of a person of ordinary skill in the art. See, generally, Prelim. Resp. Based on a review of the record, we adopt Petitioner’s proposed level of ordinary skill in the art because it is consistent with the evidence of record, including the asserted prior art and ’947 patent specification.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalTerm construed patent owner constructionDecided for patent owner

      “not agree, based on the current record, that the claims should be construed to encompass a device that has independent RFID transponder components that are separate from and independent of the components that provide voice call capability. During prosecution of related applications, in distinguishing Zalewski, Applicant disavowed such a broad interpretation. For example, Applicant asserted: The term “transceiver” . . . is well understood by those of ordinary skill in the art. One of ordinary skill in the art would not reasonably interpret a "transceiver" so broadly as to incorporate an entire mobile device's circuitry, and in particular to be read on by two separate transmitters . . . . Ex. 1008, 40. Also: [A] person having ordinary skill in the art would have understood “a transceiver of a mobile communication device” to be a transmitter and receiver combined in a single package/housing/unit and sharing at least some common circuitry for both transmission and reception located within a mobile communication device. . . . . A person having ordinary skill in the art would understand Applicants’ disclosure as describing a single transceiver that can be switched from a first state in which it transmits voice call signals to a second state in which it transmits RFID signals. Id. at 92, 94. However, Petitioner also argues, and provides expert testimony in support, that it would have been obvious to integrate Willgert’s communications unit with the voice call capability of a mobile telephone. Pet. 53–54 (citing Ex. 1003 ¶¶ 129–130). At this stage of the proceeding, we find support for this position, including the fact that Willgert specifically teaches that the communications unit can be integrated into a mobile telephone. Ex. 1004 ¶ 32. Patent Owner challenges this argument based on the statement in Willgert that the communications unit can be “constructed so that the transponder will also function when the mobile telephone is switched-off.” Prelim. Resp. 13–15 (citing Ex. 1004 ¶ 31). However, Willgert provides this as one option, and we do not find that this statement teaches away from a fully integrated approach alternative.” slip op. at 30

      “Under 35 U.S.C. § 325(d), the Board may exercise discretion to deny a petition that presents the same or substantially the same art or arguments as were previously presented to the Office. See 35 U.S.C. § 325(d); 37 C.F.R. § 42.4(a) (providing that the Board institutes on behalf of the Director). The Board has outlined factors it considers in determining whether to exercise discretion to deny institution under § 325(d): (a) the similarities and material differences between the asserted art and the prior art involved during examination; (b) the cumulative nature of the asserted art and the prior art evaluated during examination; (c) the extent to which the asserted art was evaluated during examination, including whether the prior art was the basis for rejection; (d) the extent of the overlap between the arguments made during examination and the manner in which Petitioner relies on the prior art or Patent Owner distinguishes the prior art; (e) whether Petitioner has pointed out sufficiently how the Examiner erred in its evaluation of the asserted prior art; and (f) the extent to which additional evidence and facts presented in the Petition warrant reconsideration of the prior art or arguments. Becton, Dickinson & Co. v. B. Braun Melsungen AG, IPR2017-01586, Paper 8, 17–18 (PTAB Dec. 15, 2017) (precedential as to § III.C.5, first paragraph) (“Becton Dickinson”).

Advanced Bionics, LLC v. MED-EL Elektromedizinische Geräte GmbH, IPR2019-01469, Paper 6, 8–10 (PTAB Feb. 13, 2020) (precedential). Advanced Bionics explains how the Becton Dickinson factors fit into a two-part framework that examines: (1) whether the same or substantially the same art previously was presented to the Office or whether the same or substantially the same arguments previously were presented to the Office; and (2) if either condition of first part of the framework is satisfied, whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundOther

      “Petitioner argues that this combination would have been motivated by the fact that the Willgert teaches that integrating its communications unit into a mobile telephone designed for Bluetooth communication was a “highly user-friendly application,” and that it was well known practice to use a Bluetooth headset wirelessly communicating with the phone to enable hands-free phone calls, as specifically taught by Mooney. Pet. 12–14 (citing Ex. 1004 ¶¶ 8, 30–32; Ex. 1005, Fig. 3, ¶¶ 7, 39, 46–48; Ex. 1021; Ex. 1003 ¶¶ 72–76). Petitioner further argues that Bluetooth headsets were widely available, that incorporating the headset involved known methods yielding predictable results, and that one of ordinary skill would have reasonably expected to succeed in combining the teachings of Willgert and Mooney. Id. at 15–16 (citing Ex. 1004 ¶¶ 8, 10; Ex. 1005, ¶ 8; Ex. 1017, 1, 3; Ex. 1021, 2; Ex. 1003 ¶¶ 77–79). Patent Owner does not address the issue of motivation to combine Willgert and Mooney.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAOther

      “Willgert/Mooney combination does not teach or suggest the voice call signal requirements of the claims. As stated in the ’984 patent, the voice call signals relate to “the primary function of [the mobile communications device], i.e. to facilitate a user in communicating with another user of another communication device.” Ex. 1001, 3:47–49. The proffered combination of wirelessly connecting a Bluetooth headset to the Bluetooth receiver/transmitter of Willgert’s communications unit includes the fact that the Willgert communications unit is integrated into a mobile telephone. Ex. 1004 ¶¶ 30, 32. Thus, when the telephone is being used for its “primary purpose” of communicating with another user, the same voice call signal involved in that communication is also being transmitted from the telephone to the Bluetooth headset. We see no reason why the claimed “voice call signals” must be construed to exclude such signals. Patent Owner declined to address claim construction in its Preliminary Response, but is free to explore this issue post-institution. We also disagree, based on the current record, with Patent Owner’s assertion that Willgert’s RFID transponder 2 does not transmit “RFID transponder data” or “RFID transponder signals.” The very term itself — RFID transponder — as well as the explicit disclosures in Willgert, establish that the RFID transponder transmits RFID signals and data. Ex. 1004 ¶¶ 4, 14–19. Although, as Patent Owner points out, the ’984 patent discloses embodiments that “emulate” an RFID transponder, there is no reason to confine the scope of the claims to the disclosed embodiments and there is nothing in the ’984 specification or claims that disavows including Willgert’s RFID transponder within the scope of the claims. Also, Patent Owner’s reliance on the prosecution history regarding the Zalewski patent is misplaced. As Patent Owner has explained, Zalewski disclosed “‘an RFID transponder 110’ embedded in a removable cover for a phone or other device ‘such as an MP3 player.’” Prelim. Resp. 14 (citing Ex. 2001, 7:63–8:3). Based on this, Applicant successfully distinguished Zalewski because the RFID transponder functionality, being contained in a removable cover, was completely independent of the phone device, and thus the claim requirements of a transceiver or transmitter switching between a voice call state and an RFID transponder state were not met. Ex. 1002, 18, 91, 134–135, 155; Ex. 1009, 530. Zalewski was not distinguished based on whether or not the RFID transponder was emulated. Again, Patent Owner is free to explore the scope of the claim terms “transceiver” and “transmitter” post-institution.” slip op. at 22

Patent Owner provides no evidence of a significant relationship between Petitioner and Cisco, but nonetheless argues that factors 1–5 favor discretionary denial anyway, because Petitioner had knowledge of the Cisco petition, citing the Board’s decision in Ericsson Inc. v. Uniloc 2017, LLC, IPR2019-01550, Paper 8 at 11–12 (PTAB Mar. 17, 2020) (“Ericsson”), for the proposition that Petitioner’s use of the Cisco petition as a roadmap ties the interests of the petitioners together. Prelim. Resp. 26. We are not persuaded by this assertion. First, Ericsson is not a precedential or informative decision and is not binding on us or informative to our analysis. Moreover, in that case there were five prior petitions that covered all of the challenged claims, and the petitioner admitted crafting its petition based on its review of the prior petitions. Ericsson at 3, 11. Petitioner here has not made such a concession, and moreover, Patent Owner has not presented any evidence that Petitioner actually did use the petition in IPR2024-00506 as a roadmap. Under the circumstances, we find no evidence that Petitioner used the prior petition filed by Cisco as a roadmap, particularly when none of the timing associated with the prior petition was within its control. We find no significant relationship between Petitioner and Cisco. “[W]here, as here, the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors.” Videndum Prod.

      “sufficient showing that a POSITA would have been motivated to apply Hu’s concept of aggregating ports to form a high-capacity port for transmitting multicast streams to the network device disclosed by Blease, and we do not agree that Blease teaches away from incorporating such aggregation. Both Blease and Hu are directed to similar subject matter, processing multicast stream requests, and Hu’s link aggregation addresses the problem of potentially overloading a port when doing so. See, e.g., Ex. 1005, code (57) (“The network device transmits multicast traffic to the subscriber devices.”); Ex. 1007, claim 17 (“A network device to allocate media streams . . . .”), 1:20–29 (disclosing that, if “insufficient bandwidth [is allocated] to video streams, the quality of service degrades”); see Intel Corp. v.

Cir. 2023) (“That [two prior art references] address the same problem and that [one of the references] was a known way to address that problem is precisely the reason that there’s a motivation to combine under KSR and our precedent.”). On this record, we are persuaded that applying Hu’s port aggregation teaching to Blease’s router would be the application of a known technique to improve the router to allow it to provide multicast streams that require higher bandwidth with predicable results. Pet. 28; see KSR, 550 U.S. at 415–21. As pointed out by Petitioner, these two concepts could be combined together in a straightforward manner and applied to streams that require high-capacity ports, a technique already applied elsewhere in Blease to other ports, so a POSITA would have had a reasonable expectation of success in doing so. Pet. 28–29; Ex. 1003 ¶¶ 93–94; see Elekta Ltd. v. Zap Surgical Sys., Inc., 81 F.4th 1368, 1377 (Fed. Cir. 2023) (“Evidence of reasonable expectation of success, just like evidence of a motivation to combine, ‘may flow from the prior art references themselves, the knowledge of one of ordinary skill in the art, or in some cases, from the nature of the problem to be solved.’”) (quoting Brown & Williamson Tobacco Corp. v. Philip Morris Inc., 229 F.3d 1120, 1125 (Fed. Cir. 2000)). On this record, we are unpersuaded by Patent Owner’s argument that Blease teaches away from using aggregated ports to form a high-capacity link because “Blease’s disclosure is clear that the focus of its multicast techniques is to reduce, not increase, the amount of multicast traffic flowing through network.” Prelim. Resp. 14. The discussion in Blease of minimizing the bandwidth does not relate to restricting the bandwidth required for a particular stream as Patent Owner seems to assert, but rather to eliminating duplicate transmissions of the same multicast stream to be delivered to multiple subscribers. See Ex. 1005, 2:39–42, 4:50–56 (“The multicast transmission techniques described herein may significantly reduce the amount of multicast traffic . . . . For example, regardless of the number of subscriber devices[] connected to the same network switch that request the same multicast stream, [the] network device[] only sends one copy of the multicast stream to the network switch.”). Therefore, aggregating ports to accommodate transmission of a single multicast stream that requires more bandwidth is a different concept that is unrelated to the discussion in Blease about minimizing bandwidth by increasing efficiency.” slip op. at 37

      “access switches on the second port.” Ex. 1001, claim 5. We find that Petitioner has not provided sufficient information for us to find a reasonable likelihood that Gai teaches or suggests dependent claims 5 and 17 at this time. Dependent claim 17 is similar to claim 5, but depends on claim 16 (which in turn depends on independent claim 13), adding “wherein the protocol processor is adapted to update the entries in the database to point to the second access port before receiving the communication traffic from the one or more access switches on the second port.” Id. at claim 17. These claims both require the switch implementing the method for rapid recovery, such as switch 124 in Petitioner’s example discussed above, to update its filtering database before receiving communication traffic from access switches, such as access switches 115 and 116 in Petitioner’s example. Pet. 58. That effectively means that switch 124 must update its database immediately upon transitioning to the new port either before or at the same time it transmits dummy messages to the access switches. So this differs from the analysis for claim 4 because allowing the corresponding entry in the filtering database to time out will not be sufficient to ensure that the entries will be updated before receiving communication traffic from one of the access switches. There is no express disclosure from the portions of Gai cited by Petitioner of immediately updating the database on the switch implementing the method. Pet. 57–58, 94; Ex. 1005, 2:30–41, 5:36–39, 5:54–56, 12:62– 65. Based on the current record, we are also not persuaded by Petitioner’s declarant’s explanation of why Gai allegedly teaches or suggests this limitation. In the section addressing dependent claim 5, Dr. Houh asserts that: are transmitted before any communication traffic is received by the switch. As I discuss in Section VIII.A.5.ii, the filtering database is updated before transmitting the dummy messages. Accordingly, a POSITA would have understood that the database entries would have been updated before receiving any communication traffic from the access switches. Ex. 1003 ¶ 139. However, Section VIII.A.5.ii of Dr. Houh’s declaration relates to dependent claim 4 which does not have any timing requirement, and the citations to Gai there do not describe that the switch first updates its filtering database before sending the dummy message.12 Id. ¶¶ 133–136. Therefore, the conclusory and unsupported assertions that Gai teaches or suggests this limitation, or renders it obvious to a POSITA, do not persuade us that Petitioner has shown a reasonable likelihood of prevailing on these claims, at least at this stage of the proceeding.” slip op. at 58

      “Id. Therefore, after a failure and switchover, edge switch 124 transmits dummy traffic to access switch 116 over the second link. Id. Based on the current record, we agree that this example is at least suggested by Gai’s teaching that “the method and apparatus manifests, in part, as a series of novel commands that may be entered at the devices. The devices, moreover, may be classified as either access switches or backbone switches.” Ex. 1005, 6:6–9. Switch 124 is a backbone switch because it interconnects at least access switches 114–116, and, according to Gai, the invention can be implemented on that switch by entering the corresponding commands on it. Id. The rest of the example, whereby ports are switched based on a failure and dummy traffic that is transmitted to the access switches updates their filtering databases, also follows Gai’s teaching. Pet. 39–46; Ex. 1005, 5:35– 6:12. Patent Owner responds to this argument by asserting that “Gai itself never describes backbone switch 124 in such a way,” disputing it could transmit dummy traffic to access switch 116 over the second link. Prelim. Resp. 10–11. Rather, according to Patent Owner, “Gai clearly explains that such an action is in response to a port failure in access switch 114, not in teaching to the preferred embodiment that describes the failure occurring at switch 114, which we do not find warranted in view of the general teaching from Gai discussed above saying the invention can also be implemented on backbone switches.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
