“Regarding spatial diversity, Dou explains that a first internal antenna and a second internal antenna “may be separated by a distance (D) that is no less than the quarter wavelength (>=λ/4) of the lowest frequency.” Ex. 1013 ¶ 24; see Ex. 2010 ¶¶ 35, 44. Consistent with Dou’s preference for at least a quarter-wavelength spacing between antennas at the lowest frequency, “a commonly accepted rule of thumb is that at least a quarter-wavelength spacing between antennas is necessary to provide effective spatial diversity.” Ex. 2010 ¶¶ 33, 35, 47. Effective spatial diversity requires sufficient spacing between antennas because that technique “uses multiple antennas to improve signal reliability and performance by mitigating the effects of multipath fading and other interference.” Ex. 2010 ¶ 33. “Multipath fading occurs when a wireless signal propagates along multiple different paths of differing lengths because of interactions with obstacles, resulting in portions of the signal energy arriving at a receiver with different phases slightly offset in time.” Id. Locations insufficiently separated in terms of wavelength “tend to experience similar fading and interference characteristics.” Id. Thus, closely spaced antennas “cannot provide effective spatial diversity.” Id. By providing sufficient spacing between antennas, however, “the likelihood increases that at least one of the antennas will be positioned at a location where the multipath or other interference is relatively low, thereby improving overall signal quality and reliability.” Id. As Patent Owner contends, the proposed combination modifies Dou’s ground plane 310 to replicate Jing’s ground plane with dimensions of 36 mm × 60 mm and limits “the extent of Dou’s ground plane 310 so that it [does] not extend behind Jing’s antenna at 306, just like Dou does not extend it behind antenna 308.” See Pet. 35–36; Prelim.

“3. Motivation to Combine Buibas and Sinyavskiy Petitioner argues that “it would have been obvious to partition Buibas’[s] spiking networks according to the specific techniques disclosed in Sinyavskiy” for multiple reasons. Pet. 13 (citing Ex. 1005 ¶¶ 71–72, 85, 92, 179–203; Ex. 1006 ¶¶ 12, 185, 188, 191, Fig. 6A; Ex. 1003 ¶ 63). First, Petitioner asserts, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to parallelize task execution on the robot and improve learning capabilities (e.g., through faster learning, greater computing efficiency, and task-specific learning models) of the Buibas mobile robotic apparatus as described by Sinyavskiy and discussed by Dr. Janet.” Id. (citing Ex. 1003 ¶ 64). Second, Petitioner contends, “partitioning Buibas’[s] robotic brain as suggested by Sinyavskiy would have beneficially expanded the range of tasks that the robot could perform by dedicating partitions to specialized tasks.” Id. at 13– 14 (citing Ex. 1006 ¶¶ 12, 185, 188, Fig. 6A; Ex. 1005 ¶¶ 71–72, 85, 92, 179–205; Ex. 1003 ¶ 65). Third, Petitioner argues, one of ordinary skill “would have been motivated to partition Buibas’[s] spiking neural network as suggested by Sinyavskiy to permit unused partitions or unused resources in the partitions to be reassigned for different tasks,” which would allow for a network processing apparatus that has increased processing capability for the same network capacity while also having a lower cost, size and power consumption. Id. at 14 (citing Ex. 1006 ¶¶ 190–192, 105, 34, code (57); Ex. 1003 ¶ 66). Fourth, Petitioner argues that “Buibas briefly mentions that its spiking neural networks can be partitioned but discloses little detail about the partitioning,” which would invite one of ordinary skill to turn to other references, such as Sinyavskiy, for additional detail on how to implement partitioning. Pet. 14–15 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 67). Fifth, Petitioner asserts, combining Buibas and Sinyavskiy would merely “involve[] the application of known techniques (e.g., Sinyavskiy’s partitioned neural network) to a known system (e.g., Buibas’[s] mobile robot and robotic brain) to yield predictable results (e.g., Buibas’[s] robot using a spiking neural network partitioned as taught in Sinyavskiy),” particularly because “the partitioning of the Buibas neural network is reminiscent of Recurrent Fuzzy Neural Networks (RFNNs) that were already commonplace at the end of the 1990’s.” Id. at 15 (citing Ex. 1003 ¶ 68). Finally, Petitioner contends, the proposed combination merely involves “use of known techniques (e.g., Sinyavskiy’s partitioned neural network) to improve a similar system (e.g., Buibas’[s] mobile robot and robotic brain).” Id. (citing Ex. 1003 ¶ 69). Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70).” slip op. at 14

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.

“The parties’ proposed levels of ordinary skill in the art are similar, although Patent Owner proposes two years of experience along with a bachelor’s degree whereas Petitioner proposes “significant” experience. Patent Owner also proposes an alternative with more extensive experience in lieu of a bachelor’s degree. Although we find Petitioner’s proposed qualifications 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 ordinary skill necessary to understand and implement the teachings of the ’680 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).

“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

“Based on the full trial record, we continue to adopt Petitioner’s definition of the level of ordinary skill in the art, which is consistent with the ’430 patent and the prior art. In adopting this definition, we note that neither the title nor the “Field of the Invention” portions of the ’430 patent limit the invention to integrated circuits, and Patent Owner does not dispute that claim 1 encompasses inductors that are not provided on an integrated circuit. Ex. 1001, code (54), 1:16–22. Additionally, Dr. Prucnal’s definitions have shifted, and his latest definition purports to be based on Dr. Tentzeris’s characterization of the level of ordinary skill, but changes “experience designing integrated circuits or inductors for semiconductors” to “experience designing integrated circuits and inductors for semiconductors” without sufficient explanation of the reasons for the change.

“After considering the full trial record, we agree with Petitioner that the phrase “on a semiconductor die” in the preamble of claim 11 is not limiting. First, we determine that the phrase “on a semiconductor die” in claim 11 does not provide antecedent basis for terms in the body of the claim. The body of claim 11 does not refer to “the semiconductor die” or even mention the “semiconductor die” at all, and neither do any of the claims that depend from claim 11. We disagree with Patent Owner’s argument that the phrase “on a semiconductor die” in the preamble of claim 11 provides antecedent basis for the term “the first inductor” in the body of the claim, because the “first inductor” language in the preamble provides antecedent basis for “the first inductor” language in the claim’s body. The “on a semiconductor die” language in the preamble is presented separately and can be easily parsed from the preamble’s language reciting a “first inductor” without impacting the understandability or grammatical completeness of claim 11. Therefore, the “on a semiconductor die” language in claim 11’s preamble is not necessary to provide antecedent basis for the phrase “the first inductor” in the body of claim 11. This use of language in claim 11 is distinguishable from the Federal Circuit’s opinion in Deere v. Bush Hog, cited by Patent Owner, where the preamble term “rotary cutter deck” provided antecedent basis for the term “said deck” recited in the claim body, because in Deere, the words “rotary cutter” appeared directly before, directly modified, and were not easily parsed from the term “deck.” See Deere & Co. v. Bush Hog, LLC, 703 F.3d 1349, 1357–58 (Fed. Cir. 2012); PO Resp. 7–8.” slip op. at 12

“We agree with Petitioner that claims 1 and 11 do not require that the first and second inductor be laterally spaced, but instead merely require that the second inductor be positioned at a “predetermined distance” from the first inductor. Nothing in the claim language restricts this “predetermined distance” from being in the X, Y, or Z direction, or requires that the inductors be laterally spaced in the same plane. Moreover, the fact that the ’430 patent Specification describes embodiments where the inductors are laterally spaced in the same plane does not limit the claims to those embodiments. As explained previously, our reviewing court “has expressly rejected the contention that if a patent describes only a single embodiment, the claims of the patent must be construed as being limited to that embodiment.” Liebel-Flarsheim, 358 F.3d at 906. “Even when the specification describes only a single embodiment, the claims of the patent will not be read restrictively unless the patentee has demonstrated a clear intention to limit the claim scope using ‘words or expressions of manifest exclusion or restriction.’” Id. We see no such “words or expressions of manifest exclusion or restriction” here. Accordingly, we give the term “predetermined distance” its ordinary meaning, which includes a distance in any direction. The parties do not dispute that Taniguchi’s inductors are spaced apart with an insulation layer in between. Therefore, under the ordinary meaning of the claim language, Taniguchi’s second inductor is “positioned at a predetermined distance from the first inductor.”” slip op. at 26
- Prior constructionPrior construction adoptedDecided for patent owner
“We agree with and adopt the ITC’s construction of “closely spaced,” which is “two terminals in proximity to each other (such that the electromagnetic field at a certain distance from the first inductor (where the second inductor is positioned) is reduced.” Ex. 1020, 12. We find that this construction is supported by the intrinsic record, including the Specification of the ’430 patent, which shows terminals being “closely spaced” compared to the dimensions of the inductor itself, and explains that the purpose of the close spacing is to make the field contributions from the two parts of the inductor identical. See Ex. 1005, Figs. 1–2, 4:28–32. Claims 1 and 11 of the ’430 patent lack specific dimensions for either the inductor or the spacing between the terminals, and indicate that the purpose of the close spacing is to “minimiz[e] magnetic field contributions from the terminals.” Ex. 1001, 10:22–25, 11:7–10. Dr. Prucnal’s ITC declaration, although not intrinsic evidence, further supports our conclusion. Although Patent Owner does not propose a construction for “closely spaced terminals,” it appears to argue that this term must be interpreted based on the dimensions of the semiconductor chip described in the ’430 patent. PO Resp. 43. We do not see any basis in the intrinsic or extrinsic evidence to impart such a narrow reading to the claim language, particularly because the ’430 patent Specification does not define the “closely spaced terminals” in relation to a semiconductor chip, and claim 1 is not limited to inductors on a semiconductor chip.” slip op. at 40

“Ex. 1001, 4:46–50. This passage indicates that the interconnect can be a network on a chip and the network on a chip can include wires and buses. That does not necessarily mean that the interconnect can be just wires or buses; rather, it discloses that the interconnect can include wires and buses. In context, the disclosure regarding wires and buses does not support construing the corresponding structure broadly enough to encompass just wires and buses. The networks that constitute the corresponding structure, however, could include networks with wires and buses. Therefore, we agree with Patent Owner that the corresponding structure for the interconnect means should not include a mere bus, switch, and point-to-point wire and instead find that the corresponding structure under 35 U.S.C. § 112 ¶ 6 is a network, which the ’052 patent describes as a multi-hop interconnection between modules separated by one or more network nodes. See Ex. 1001, 2:33–37. Because this structure corresponds to the construction of “interconnect means” proposed by Patent Owner and adopted by the district courts in the TI and Qualcomm litigations (see supra Section III.C.3.b), and we do not rely in our analysis below on a recourse to “equivalents thereto” as permitted by § 112 ¶ 6, we note that our ultimate conclusions on the unpatentability of the challenged claims would be the same if § 112 ¶ 6 did not apply. iii.
