      “Petitioner “does not believe any terms require a formal construction.” Pet. 6. Patent Owner agrees “no claim terms presently require construction to resolve any current dispute between the parties.” PO Resp. 15. We do not discern a need to construe explicitly any claim language at this juncture because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties.

      “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra. Id. ¶ 19; see also In re Etter, 756 F.2d 852, 859 (Fed.

      “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

      “taught by “the horizontal position of the electronic shelf label along the horizontal shelf part 21, as shown in FIG. 4.” Pet. 21 (citing Ex. 1009 ¶ 75). Certainly, each shelf label in the real world, as well as in the drawing of Figure 4, has a horizontal position. However, that does not mean that Fujiwara’s database stores information indicating the horizontal position of the shelf label as required by the claim. The claim is not calling for the shelf label to have a location; it is calling for location information to be accessible by the server so that the server can determine the location of the mobile terminal. Ex. 1001, 8:19–24 (claiming a “method being performed by a central server configured to access a planogram associating . . . identifiers . . . with . . . locations . . . defined by a vertical and horizontal position”), 8:41–46 (claiming a method step of “determining a location of the mobile terminal . . . based on . . . the planogram). For example, fields in a database storing horizontal and vertical positions would be sufficient. Id. at 6:31–36 (“The central server 2 determines the location of said mobile terminal 1 from the identifier of said electronic label 3 using the data of a planogram associating a location with the label identifier.”), 7:16–18 (calling for the planogram to be stored in a database). To the extent we accept that Fujiwara teaches a unique identifier (shelf label ID) and a vertical position (e.g., shelf number 21-1), we find Fujiwara to be missing a horizontal position as required by the claim because neither the shelf number nor the shelf label ID provides an indication of where along the shelf the shelf label is located.” slip op. at 14

      “We begin our analysis by pointing out that neither party offers a claim construction of “cascaded transistors,” though both parties reference the understanding of the term set forth by Petitioner’s declarant. Although we do not reject Petitioner’s declarant’s definition, we also do not adopt it as the meaning of “cascaded transistors” at this time, absent the parties’ proposal that we do. According to the ’886 patent, transistors simply “coupled in series” are “cascaded.” Ex. 1001, 6:50–51. We use this disclosure to guide our analysis. Reviewing Figure 7 of Okashita, we see a configuration of transistors 1 and 2 that appears, on this record, to be coupled in series. When transistor 2 acts as a shunt for transistor 1, i.e., when the threshold voltage of transistor 2 has been overcome, then current flows through transistor 1, through transistor 2, and then to ground.

It is not clear to us on this record that Patent Owner is correct that keeping AC and DC grounds separate is not present in Burgener, given that Burgener has both AC signals coming in from ports A–D, as well as digital control signals coming in from the control ports (e.g., 1708 and 1718, for port A). See Ex. 1006 ¶¶ 100–101 (discussing RF ports and control signals).

      “1. Means-Plus-Function Terms Challenged claim 26 recites elements using the word “means.” See Ex. 1001, 21:6–22:5. The use of the word “means” in a claim element creates a rebuttable presumption that 35 U.S.C. § 112 ¶ 6 applies.9 See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part). Construing a means-plus-function claim term is a two-step process. We must first identify the claimed function. Then, we must determine what structure, if any, disclosed in the specification corresponds to the claimed function. Id. at 1351 (citation omitted). The parties do not dispute that 35 U.S.C. § 112 ¶ 6 applies to those “means” elements recited in claim 26. See Pet. 6–8; see generally Prelim.

      “Petitioner argues that these terms “should be construed to include both mismatch errors and errors that may eventually result in mismatch errors constituting a ‘precursor to lockstep mismatch’—including at least one of (1) detecting a lockstep mismatch error; and (2) detecting an error that may eventually cause a lockstep mismatch error.” Pet. 6. Petitioner asserts that “[t]he specification provides detecting these two types of errors as examples of detection of LOL.” Id. (citing Ex. 1001, 2:40–3:6, 7:25–36; Brogioli Decl. ¶¶ 34–36). Petitioner further asserts that this construction “is consistent with the undisputed construction in the IPR challenging U.S. Patent No. 7,502,958.” Id. (citing BMW of N. Am., LLC v. Foras Techs.

Therefore, we determine that at this stage, we do not need to expressly construe these claim terms to resolve a controversy. 3. Summary and Conclusion For the reasons given, we determine that at this stage, we do not need expressly to construe any claim term for this Decision. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “As can be seen in the discussion above and the analysis of Petitioner’s grounds below, Arai and Landry are significant to Petitioner’s challenges. Because the Office did not previously consider all of the prior art references or combinations of references relied on in the Petition, including Arai and Landry, and because Arai and Landry are not the same or substantially the same as the art that was previously considered, we determine the Office did not previously consider the same or substantially the same prior art as is relied on in the Petition.8 Further, we find that there is not a substantial overlap, if any, between the arguments made during examination and the manner in which Petitioner relies on the prior art, including Arai and Landry, as discussed above. Therefore, part one of the Advanced Bionics framework is not met, and we need not proceed to part two of the Advanced Bionics framework.

      “Motivation to Combine Fox, Safford, and Arai and Fox, Safford, Landry, and Arai Petitioner asserts that a person of ordinary skill “would have found it obvious to combine Fox’s multiprocessor system with Safford’s lockstep processor and error detection logics and Arai’s processor-switching implementation details.” Pet. 10. Dr. Brogioli testifies that “[a person of ordinary skill] would have been motivated to implement the processors in Fox as lockstep processors to improve reliability and availability of Fox’s server system for critical processes, for which higher reliability and availability of the system are desired.” Brogioli Decl. ¶ 90. He further testifies that “[a person or ordinary skill] also would have been motivated to implement in Fox the error detection logics that detect loss of lockstep together with the lockstep processors as taught by Safford to implement lockstep functions and further improve availability of the system.” Id. He testifies that “[a person of ordinary skill] would have understood how to implement Fox’s processors as lockstep processors with error detection logics and expect success. [A person of ordinary skill] would only have applied well-known configurations and ordinary hardware and software configuration skills.” Id. ¶ 91. Dr. Brogioli provides additional reasons motivating the combination. Id. ¶¶ 92–99. Petitioner contends that “Arai discloses switching the role of a failing processor with a spare processor.” Pet. 10. Dr. Brogioli testifies that “[a person of ordinary skill] would have been motivated to incorporate Arai’s teaching of transferring processor context from the failing processor to the spare processor not to interrupt the operating system and its running applications as desired by Fox.” Brogioli Decl. ¶ 109. He reasons that “[a person of ordinary skill] would have understood that incorporating Arai’s benefit of switching the role of the failing processor to the spare processor without affecting the operating system and running applications, which is expressly taught as desirable by both Fox and Arai and well known in the art.” Id. ¶ 110. Petitioner asserts that a person of ordinary skill also would have been motivated to further combine these references with Landry. Pet. 33–35. Dr. Brogioli testifies that “Landry discloses a fault-tolerant boot process that dynamically designates a functional CPU as logical CPU0 that performs the unique functions of a boot processor.” Brogioli Decl. ¶ 147. He testifies further that “[a person of ordinary skill] would have understood Landry’s process would have been a suitable option for selecting a boot processor in Fox’s system consistent with the initialization protocol of the IA-32 multiprocessor system.” Id. He asserts that “[a person of ordinary skill] would have understood the benefits of implementing Landry’s boot processor selection process in Fox.” Id. ¶ 148. Among other reasons, “[a person of ordinary skill] would have further understood that using the logical CPU0 as the identification for the boot processor allows for transparent replacement of the physical processor experiencing a failure with another processor without interrupting the operating system.” Id. At this stage, Patent Owner does not respond to these arguments by Petitioner or refute the testimony by Dr. Brogioli. On this record, we find that Petitioner has sufficiently demonstrated a motivation to combine Fox and Safford with Arai and to further combine these references with Landry with a reasonable expectation of success.” slip op. at 29

      “instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” There is no dispute that Patent Owner served Petitioner with a complaint alleging infringement of the ’808 patent on March 15, 2023. See Mot. 2 (Mountain Voyage identifying March 15, 2023 as the date it was served with Patent Owner’s complaint in the United States District Court of Colorado). There is also no dispute that Mountain Voyage filed the instant Petition more than one year later on August 6, 2024. Pet. 91. Therefore, the evidence in this record shows that Mountain Voyage’s Petition was filed more than 1 year after the date on which Mountain Voyage was served with a complaint alleging infringement of the ’808 patent. Mountain Voyage relies on its request to join the Shenzhen IPR to avoid the time bar of 35 U.S.C. § 315(b).
