“d) Analysis Re Construing “Voice Call Signals” We conclude that it is unnecessary to define “voice call signal.” Patent Owner’s construction would read into the term additional limitations that are for the most part already set forth in the claims: “a switchable mobile communications device capable of . . . voice call communication” (claims 1, 13, 21, 32); “output . . . a voice call signal for transmission . . . over a wireless network” (claims 13, 21, 32); “wherein the mobile communication device is a selected one of a wireless mobile phone and a personal digital assistant equipped with communication capability” (claims 12, 20, 31, 39). Thus the claims require a mobile communications device that is capable of communicating a voice call signal, but do not restrict the voice call signal to only be communicated by a mobile communications device. Likewise, claims 13, 21, and 32 (but not claim 1) require the voice call signal to be transmitted over a wireless network, but do not restrict transmission to only a wireless network, and do not restrict the wireless network to “a network of a wireless network service provider,” as Patent Owner would require.” slip op. at 15

“construction for the RFID transponder signal or data terms — it is sufficient for purposes here to conclude that the claims encompass Petitioner’s “functional emulation” articulation. See Reply 11–12. That is, the purpose of the frequent references to “emulated,” “emulation,” or the like in the ‘984 patent is to emphasize the fact that the mobile communications device of the claims has a dual role: to provide voice call communications, and to transmit RFID transponder data. In the latter role, transmitted RFID transponder data appears to an RFID reader to have been transmitted from an ordinary RFID transponder. But there is no need to rewrite the claims to restore the emulation terms, given that, as we discuss further below, Patent Owner deliberately removed those terms during prosecution.

“device “[f]or the treatment of large-area tissues,” such as the backs of human patients, wherein several applicators 13 are “flexibly connected to each other through hinges.” Id. (quoting Ex. 1004 ¶ 72). Petitioner asserts that a POSITA would have been motivated “to incorporate Larsen’s solution of connecting light applicators by hinges, to allow for adjustability of Lundahl’s device to provide the desired irradiance and irradiance uniformity to all target areas during PDT.” Id. (citing Ex. 1015 ¶ 127).

Petitioner’s proposed modification of Lundahl also involves using LEDs as a light source instead of Lundahl’s fluorescent tubes. Id. According to Petitioner, a POSITA would have been motivated to make this change because: (1) LEDs had a lower cost and a longer lifetime than fluorescent tubes; (2) fluorescent tubes were known to have inconsistent light output within the tube itself; and (3) “the use of LEDs would be more practical to reduce spacing between light sources and the edges of the panels, as opposed to the bulky metal couplings at the end of fluorescent tubes, to reduce optical dead space across the light surface.” Id. (citing Ex. 1014, 4:41–42, 6:31–42; Ex. 1015 ¶ 129). Petitioner asserts that a POSITA would have had a reasonable expectation of success with this modification because Lundahl and Larsen “describe similar illuminators and the conversion from fluorescent tubes to LEDs was a routine practice prior to 2015.” Id. at 32 (citing Ex. 1015 ¶ 131).

Patent Owner argues that Petitioner fails to identify a single prior art reference showing hinged structures on inner side surfaces. Id. This argument ignores that Larsen expressly identifies hinges on at least bottom side surfaces, and Petitioner merely proposes modifying their location from the bottom sides to inner sides. We find credible Dr. Grove’s testimony that relocating hinges would have been within the level of ordinary skill in the art. Ex. 1015 ¶ 155.

“We disagree. Although claim 1 recites step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Here, nothing in the express claim language precludes performing step 1d before step 1b.

For example, the claim does not contain temporal terms like “then,” “next,” or “further.” Although Patent Owner points out that a term of step 1d (i.e., “the” one more available devices) derives antecedent basis from step 1b, this alone does not require performing step 1b before step 1d.

“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.

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.
