“Dr. Papanikolopoulos’s testimony that Kuwata teaches away from modifying its camera 22 to access an external server (such as Fisher’s Internet-enabled external data source) by stressing advantages of a self-contained camera-printer pair without external dependencies. See PO Resp. 15–16, 26–28 (citing Ex. 1005 ¶¶ 75, 77); Ex. 2001 ¶¶ 61–64. The cited disclosures in Kuwata simply do not discuss any advantages arising from a self-contained camera-printer pair without external dependencies, or any disadvantages arising from connecting camera 22 to an Internet server. See Ex. 1005 ¶¶ 75, 77. The cited disclosures instead tout the advantages arising from a camera manufacturer (rather than an end user photographer) specifying the image output control information CI for a specific camera-printer pairing, to reduce differences between an image as confirmed by the end user on the camera’s display and the image outputted by the printer. See id. That advantage, however, has nothing to do with whether camera 22 may or may not communicate with an Internet server. Indeed, rather than being self-contained as Patent Owner and Dr. Papanikolopoulos would have it, we find Kuwata’s camera 22 includes an I/O port for wired or wireless communication to transmit the camera’s image files GF / 10 to various printers 24 and various personal computers (PCs). See Ex. 1005, Fig. 4, ¶¶ 81, 85; Ex. 1003 ¶ 84; Pet. 14. Thus, Kuwata allows for and does not discourage communication between camera 22 and an Internet server such as Fisher’s external data source. In particular, Kuwata does not detract from the benefits of updating image output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Moreover, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶¶ 42, 55. That teaching in Fisher dovetails with Kuwata’s disclosure concerning camera manufacturers optimizing their cameras with various different printers, supporting Petitioner’s combination. See Ex. 1003 ¶¶ 84–89, 102–108.” slip op. at 27

“articulated a reason why a person of ordinary skill in the art would have combined the teachings of Sudre, Lee, and Penven. Prelim. Resp. 60–63. In particular, Patent Owner argues that a person of ordinary skill in the art “would not have been motivated to look into Penven to modify the teachings of Lee because Lee and Penven disclose substantially different structures.” Id. at 60–61. This argument does not address Petitioner’s proposed reason to combine, which looks to Lee and Penven each to modify Sudre, not to Penven to modify Lee. See Pet. 79–81. In addition, “[c]ombining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). In other words, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425–26 (CCPA 1981). Petitioner provides “some articulated reasoning with some rational underpinning” to combine the teachings of Sudre with those of Lee and Penven. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007).

“protective layers have “a coat weight of from 5 to 30 lbs/3000 ft2,” Clearwater submits the declaration of its expert, who explains that, because Nakagawa identifies the specific polymers and the thickness of the coat used for the plastic layers and one skilled in the art “would recognize that the disclosed polymers have a given density,” then “[w]ith these known parameters, the coat weight is easily calculated to be 23.04 lbs./ 3000 ft2 — falling squarely within the claimed range.” Pet. 53–54 (citing Ex. 1003 ¶¶ 132–133; Ex. 1008 ¶ 24; Ex. 1024, at 4). At this stage, we find that testimony credible and supported by the evidence presently of record. After reviewing the preliminary record (including Clearwater’s contentions, the cited portions of Nakagawa, and the testimony of Clearwater’s expert), we find, preliminarily, that Nakagawa discloses or otherwise suggests each claim element in the manner recited by claim 1. Thus, on the current record, Clearwater demonstrates a reasonable likelihood that challenged claim 1 is unpatentable as obvious over Nakagawa. We need not decide Clearwater’s challenge of the dependent claims based on Nakagawa alone nor its challenge of claims 1–3 based on Nakagawa and Tanner. Our analysis of these challenges, in our view, is best left for trial after full development of the record.” slip op. at 8

“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.

- 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

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.

“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

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 contends that one of ordinary skill in the art “would have had at least a Bachelor’s degree in electrical engineering, material science, chemical engineering, or an equivalent field, as well as at least 2 to 3 years of academic or industry experience in the recycling or processing of lithiumion batteries. Additional formal education focusing on processing of lithium batteries may substitute for practical experience and additional practical experience can substitute for less education.” Pet. 10–11. Patent Owner does not contest this definition of a person of skill in the art. See Prelim. Resp. 11. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as, on the present record, it appears consistent with the ’463 patent and the asserted prior art.

- Expert testimonyPetitioner expert discountedPatent owner expert creditedDecided for patent owner
“distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony. Weighing this evidence all together, we find that Petitioner has failed to show that it is more likely than not that Tomioka’s teaches the claimed comminution under Petitioner’s first theory.” slip op. at 15

“obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off. Thus, we find that Petitioner has failed to show that it is more likely than not that Tomioka accounts for the claimed “comminuting.”” slip op. at 15

“both the unique sensor ID as well as the associated unique wireless device ID is contradicted, or at least unsupported, by the claim language and the Specification. We determine that this limitation does not require authentication of both the unique sensor ID and the unique wireless device ID, or otherwise require authentication using the unique wireless ID. Rather, the limitation only requires authentication of the unique sensor ID. The language and structure of the claim itself, “the remote server authenticates said unique sensor ID associated with said unique wireless device ID,” requires authentication of the unique sensor ID but not the unique wireless device ID. See Ex. 1001, 19:51–52 (emphasis added). The portion of the limitation reciting “associated with said unique wireless device ID” is linguistically an appositive modifying the “unique sensor ID.” Indeed, Patent Owner acknowledges the “plain meaning of the claim term is that the remote server authenticates the unique sensor ID and that such unique sensor ID is associated with a unique wireless device ID.” PO Resp. 18.” slip op. at 10

“Patent Owner does not contest Petitioner’s proposed constructions of any of these other claim terms or phrases. PO Resp. 24. We agree with the parties that the identified limitations—which each recite a “means” or “means for” performing a particular function—are means-plus-function limitations that should be interpreted under pre-AIA 35 U.S.C. § 112 ¶ 6. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”).

“We agree with Petitioner that the improvements offered by the incorporation of Heller’s teachings would have motivated one of ordinary skill in the art to combine the teachings of Beck and Heller in the manner proposed by Petitioner. Confirming Petitioner’s assertion that the combination yields improvements, Heller states that it improves the type of glucose monitor used in one of Beck’s embodiments. Beck states that its “medical device 130 includes a glucose meter” which “measure[s] blood glucose levels of blood applied to test strips.” Ex. 1007 ¶ 34. Specifically addressing such “conventional” test strip glucose monitoring, Heller states that its in vivo glucose sensor system addresses a need for continuous or automatic monitoring in a small, comfortable device. Ex. 1016, 2:1–7, 2:15–58, 3:19–25. As such, we agree that a person of ordinary skill in the art would have been motivated to combine the teachings of Beck and Heller to improve Beck’s medical device. See KSR, 550 U.S. at 401. We further agree with Petitioner that a POSITA would have been motivated to incorporate sensor implementation details described in Heller, e.g., an A/D converter and patient attachment systems, with Beck’s medical device.
