“In an inter partes review, the burden of persuasion is on the petitioner to prove ‘unpatentability by a preponderance of the evidence,’ 35 U.S.C. § 316(e), and that burden never shifts to the patentee.” In re Magnum Oil Tools Int’l Ltd., 829 F.3d 1364, 1375 (Fed.

Cir. 2017 (en banc (quoting Magnum Oil)). A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious to a person of ordinary skill in the art at the time the invention was made. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007) (quoting 35 U.S.C. § 103(a)). Obviousness is resolved based on underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness, i.e., secondary considerations. Graham v. John Deere Co., 383 U.S. 1, 17– 18 (1966). A party who petitions the Board for a determination of obviousness must show that “a skilled artisan would have been motivated to invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” Procter & Gamble Co. v.

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed.

“Petitioner relies on the ordinary and customary meaning of the claim terms consistent with the Phillips standard. Pet. 12–13 (citing 37 C.F.R. § 42.100(b)). The Petition addresses the construction of “peer-to-peer architecture” recited in independent claims 1 and 30 of the ’034 patent, a limitation we need not construe to decide the institution question.

Cir. 1999)). Patent Owner contends that “no claim construction is required” to address the Petition’s asserted deficiencies. Prelim. Resp. 6. Patent Owner also contends, however, that the Petition relies on a “novel claim construction” of limitations [1.4.1] and [1.5.1]—“second [third] hardware processor with a plurality of processing cores”—to support Petitioner’s obviousness argument. Id. at 11–12.8 Patent Owner challenges the Petition’s reliance on “single core processors on different chips,” such as the Power3 single-core processors of the Symmetric Multi- Processor (“SMP”) configuration disclosed in the RS6000 reference, as a disclosure of limitations [1.4.1] and [1.5.1]. Id. Patent Owner contends that such single-core processors on different chips do not satisfy limitations [1.4.1] and [1.5.1] because the ’034 patent “claims only multicore processors.” Prelim. Resp. 5 (citing Ex. 1001, 7:15–27). Petitioner responds in part as follows: To the extent PO is implicitly arguing that RS6000’s “four, eight, twelve, or sixteen 375 MHz 630FP 64-bit processors” do not teach the recited “cores,” Patent Owner’s argument excludes embodiments described in the ’034 patent’s specification. The ’034 patent describes “[p]rocessor cores [as] generally independent microprocessors.” Ex.1001, 5:14–15. Patent Owner’s attempt to exclude RS6000 from the scope of the claims 8 Pursuant to the Board’s Order on Related Matter Updates (Paper 14), the parties filed the September 26, 2025 Claim Construction Order entered in the co-pending District Court litigation in this proceeding. Ex. 1085. The District Court Claim Construction Order did not construe the claim phrase “hardware processor with a plurality of processing cores.” Id. patent where the processor has independent microprocessors. Patent Owner’s attempt to distinguish RS6000’s Symmetric MultiProcessor as a “configuration” (Paper 8, 24) also fails because a “Symmetric MultiProcessor configuration” is no different than the ’034 patent’s description of a configuration of independent microprocessors. Id. Paper 9, 30.9 It is apparent there is a dispute over the plain meaning of Limitations [1.4.1] and [1.5.1], “a second [third] hardware processor with a plurality of processing cores,” recited in the independent claims.10 The parties are ordered to propose and support a particularized plain meaning or other construction of Limitations [1.4.1], [1.5.1], and [30.1.2] in their briefs. The parties are ordered to analyze the relevant claim language and cite to the specification and prosecution history in support of their claim construction, where applicable, with particular attention to the description of a hardware processor with a plurality of processing cores in the ’034 patent.

“Motivation to Combine and Analogous Art The Petition offers several motivations to combine Menon, Trefethen, RS6000, and POEref in the manner claimed in the ’034 patent with a reasonable expectation of success, which we find sufficient on the present record. The Petition first asserts that Menon and Trefethen are analogous prior art because they pertain to the same “field of cluster computing” as the ’034 patent and “are reasonably pertinent to the problem of the ’034 patent, namely, executing a single program on multiple nodes.” Pet. 22 (citing Ex.1001, 1:14–15; Ex.1003, ¶¶ 65–69; Ex. 1005, 2; Ex. 1006, Abstract). The Petition points out that Menon expressly cites and builds on the MultiMATLAB system taught by Trefethen. Id. (citing Ex. 1003 ¶ 71; Ex. 1005, 1–2). The Petition also contends that: Accordingly, Menon and Trefethen together represent a combination of prior art elements according to known methods (executing MATLAB code on a multiprocessor system) to yield the predictable result discussed in both papers: the MultiMATLAB system executing MATLAB in parallel to perform mathematical calculations. Id. at 22–23 (citing Ex. 1003 ¶ 70; Ex.1005, Abstract; Ex. 1006, 2–7).

Indeed, the court in the Apple Litigation has concluded that the control component requirement is subject to 35 U.S.C. § 112(f), and has construed that requirement accordingly: Function: receiving control signals input to the oscillating resonant module; receiving outputs from the one or more sensors; controlling oscillation of the mass to produce a vibration response according to the received control signals by generating, using one or more of the received sensor outputs, control outputs to an actuator that drives the mass to oscillate.

“(1) Analogous Art Our reviewing court has stated that “[t]wo separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations and internal quotes omitted). While these two criteria are helpful in many instances, we must not lose sight of the key question at hand: what is “prior art” as that term is used in 35 U.S.C. § 103(a)? References that are “too remote to be treated as ‘prior art’” are excluded from the obviousness analysis. In re Sovish, 769 F.2d 738, 741, 226 (Fed. Cir. 1985). The non-analogous art test provides helpful insight on the underlying question of what is “prior art” within the meaning of the statute; we should not, however, be blind to the reality of the circumstances of the case before us.

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

“The respective proposed levels of qualifications for a person of ordinary skill in the art are similar, with Patent Owner proposing two years of experience compared to Petitioner proposing significant experience with remotely controlling fluid-handling devices, like SCADA systems. Patent Owner also proposes more extensive experience in lieu of educational experience. While we find Petitioner’s proposed qualifications to be acceptable, we adopt Patent Owner’s proposed qualifications for the purposes of this Decision because they offer a wider range of qualifications that nonetheless comport with the level of skill necessary to understand and implement the teachings of the ’871 patent and the asserted prior art. Our analysis and findings herein, however, do not turn on any differences in the qualifications adopted.” slip op. at 8

“actuators and the remote control of fluid handling devices, including the receipt with the user-interface module of “a user command to actuate an actuator via a presented control interface” (limitation [18.7]) and “account authorized to send commands to remotely control fluid handling devices” (limitation [18.11]). 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. See Ex. 1005, 10:62–67, 14:35– 15:2, 15:62–16:32; see also Pet. 12–14, 16–18. Kahn discloses that “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.” Ex. 1005, 10:62–67. 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. Rather, the disclosure indicates that the communication unit 112B includes on-site alerts and that the local (non-remote) communication unit 112B can be interfaced with the control valve.” slip op. at 18

“Petitioner argues that a person having ordinary skill in the art would have combined Izumi’s module to include multiple sensors in accordance with Cosper’s teachings. Pet. 15. Petitioner argues that the sensors would monitor the moving element and generate a control signal in accordance with Izumi. Id. at 15–16. Petitioner further argues that Izumi’s controller would have been implemented using a microprocessor and memory as Cosper suggests. Id. at 16. Petitioner argues three reasons why a person having ordinary skill in the art would have combined Izumi with Cosper’s teachings. Id. at 16–19. First, Petitioner argues that a person having ordinary skill in the art would have looked to Cosper as a way to further Izumi’s objective of having a sensor that detects the and controls the movement of the moving element. Id. at 16–17. Second, Petitioner argues that the combination of Izumi and Cosper would have enhanced reliability of the feedback sensors by capturing “data specific to different operating parameters.” Id. at 17–18. Third, combining the references’ teachings would “facilitat[e] implementation of software instructions” by using a microprocessor and memory. Id. at 18–19. Patent Owner does not dispute Petitioner’s rationale to combine the references’ teachings. Based on our review and consideration of the record, we determine that a preponderance of the evidence supports that a person of ordinary skill in the art would have combined the teachings of Izumi and Cosper in the manner Petitioner argues (“the Izumi-Cosper combination”).” slip op. at 17

“Our reviewing court has stated that “[t]wo separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations and internal quotes omitted). While these two criteria are helpful in many instances, we must not lose sight of the key question at hand: what is “prior art” as that term is used in 35 U.S.C. § 103(a)? References that are “too remote to be treated as ‘prior art’” are excluded from the obviousness analysis. In re Sovish, 769 F.2d 738, 741, 226 (Fed. Cir. 1985). The non-analogous art test provides helpful insight on the underlying question of what is “prior art” within the meaning of the statute; we should not, however, be blind to the reality of the circumstances of the case before us.
