      “decision in Revvo Technologies, Inc. v. Cerebrum Sensor Technologies, Inc., IPR2025-00632, Paper 20 (Nov. 3, 2025 (“Revvo”)).12 Revvo provides that “when a petitioner takes alternative positions [on claim construction] before the Board and a district court, that petitioner should, at a minimum, explain why alternative positions are warranted.” Revvo at 3–4. On November 5, 2025, the Director of the Office issued an informative decision in Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025- 00340, Paper 18 (Nov. 5, 2025) (“Tesla”)). Tesla provides that: “Allowing a petitioner to advance a claim construction before the Board when that petitioner has made inconsistent indefiniteness arguments in district court fails to further, but instead detracts from, the Office’s goal of ‘providing greater predictability and certainty in the patent system.’” Id. at 4 (citing Revvo at 4–5). Tesla further provides that when a petitioner raises inconsistent invalidity challenges in two forums, “that petitioner is required to explain why those different positions are warranted.” Id. at 3 (citing Revvo at 3–5). In this proceeding, Petitioner takes alternative positions on claim construction before the Board and a district court, but fails to explain why alternative positions are warranted. Therefore, in accordance with Revvo and Tesla, we deny institution.” slip op. at 6

      “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.

    • 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.

The trial date (December 2025) for the parallel proceeding is considerably earlier than the projected statutory deadline (June 2026) for issuing a final written decision in this proceeding.

      “review under 35 U.S.C. § 324 and 37 C.F.R. § 42.4(a). We may not institute a post-grant review unless “the information presented in the petition . . . , if such information is not rebutted, would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a) (2024). Upon considering the evidence and arguments presented, we determine, as discussed below, that Petitioner has not demonstrated that it is more likely than not that at least 1 of the claims challenged in the Petition is unpatentable. Therefore, we deny1 Petitioner’s request to institute post-grant review of claims 1–6.” slip op. at 2

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Patent Owner’s declarant, Dr. Khatri, proposes a definition of the person of ordinary skill in the art. Ex. 2001 ¶ 24. Dr. Khatri, however, notes that his opinions would be the same under either his proposal or Petitioner’s proposal. Id. ¶¶ 25–26. Patent Owner states that, for purposes of the Preliminary Response, it “adopts Petitioner’s definition of a person of ordinary skill in the art.” Prelim. Resp. 13 (citing Pet. 22–23; Ex. 2001 ¶¶ 22–26). We determine that the current record supports Petitioner’s description of an ordinarily skilled artisan. For purposes of this Decision, therefore, we adopt Petitioner’s description of an ordinarily skilled artisan. We also note that the applied prior art reflects the appropriate level of skill at the time of the claimed invention. See Okajima, 261 F.3d at 1355.” slip op. at 12

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

      “Petitioner proposes constructions for the claim terms “MLC memory modules” and “SLC memory module.” Pet. 23–28. Patent Owner disagrees with Petitioner’s constructions, but does not contest them because it argues that construction of these terms is not necessary to resolve the parties’ disputes. Prelim. Resp. 14. Based on the record presented, we determine that no claim term requires an explicit construction to decide whether Petitioner satisfies the “more likely than not” standard for instituting a post- grant review. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017).” slip op. at 13

    • Disclosure Requirements (§112) › Written description (Ariad)Written description adequateNot shown unpatentable

      “using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same.” The Federal Circuit has held that “[t]he written description requirement is met when the disclosure relied on for support ‘reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.’” RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1088 (Fed. Cir. 2024) (quoting Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc) (citation omitted)). The written description inquiry is a question of fact, is context specific, and must be determined on a case-by-case basis. Ariad, 598 F.3d at 1351 (citing Ralston Purina Co. v. Far-Mar-Co, Inc., 772 F.2d 1570, 1575 (Fed. Cir. 1985); Capon v. Eshhar, 418 F.3d 1349, 1357–58 (Fed. Cir. 2005)). “[T]he level of detail required to satisfy the written description requirement varies depending on the nature and scope of the claims and on the complexity and predictability of the relevant technology.” Id. (citing Capon, 418 F.3d at 1357–58). Factors used to evaluate the sufficiency of a disclosure include: 1) “the existing knowledge in the particular field”; 2) “the extent and content of the prior art”; 3) “the maturity of the science or technology”; and 4) “the predictability of the aspect at issue.” Id. (citing Capon, 418 F.3d at 1359). As support for the term “memory space,” the ’612 patent explains that because “the SLC NAND flash is used to boost the lifetime (endurance) of the storage system, it can be considerably lesser in amount than the MLC NAND flash.” Ex. 1001, 5:20–23; see Ex. 2001 ¶ 51. As an example, the ’612 specification states that “a system may set SLC NAND flash equal to 12.5% or 25% of MLC NAND flash (total non-volatile memory storage space=MLC+SLC).” Ex. 1001, 5:23–25; see Ex. 2001 ¶¶ 51, 62. In addition, we find persuasive Dr. Khatri’s testimony that one of ordinary skill in the art would have understood that “there are two spaces—MLC and SLC—where data is stored, and the total memory space is the combination of the two.” Ex. 2001 ¶ 51. Further, the ’612 patent’s Figure 1 depicts “memory space,” e.g., dynamic random-access memory (DRAM) 20, one or more disks 24, MLC NAND flash memory module 26, and SLC NAND flash memory module 28. Ex. 1001, 5:37–45, Fig. 1; see Ex. 2001 ¶ 64. The ’612 patent’s Figure 4 also depicts “memory space,” e.g., NAND flash memory bank 56 comprising “a plurality of MLC NAND flash memory modules 60a and a plurality of SLC NAND flash memory modules 62a” and NAND flash memory bank 58 comprising “a plurality of MLC NAND flash memory modules 60b and a plurality of SLC NAND flash memory modules 62b.” Ex. 1001, 7:8–14, Fig. 4; see Ex. 2001 ¶ 64. On the record before us, we find the above noted disclosures to be sufficient to support the disputed claim language. For these reasons, the ’612 patent’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” See Ariad, 598 F.3d at 1351.” slip op. at 15
