“We find Patent Owner’s arguments unavailing. In particular, we disagree with Patent Owner’s contention that the District Court provided a construction for “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service,” as recited in claim 1. Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. at 32 (citing Ex. 2002, 26)) to support its contention that the District Court construed the term “enabled,” as we determined in the Decision to Institute, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Dec. Inst. 9. As we explained, a determination of whether a term is indefinite is not the same thing as construing a claim term. Id. Thus, as we previously explained, by determining that “hybrid device” is not indefinite, the District Court did not construe the term “enabled.” Id.; see also Ex. 2002, 26. Accordingly, nothing in the Memorandum provides a construction of “enabled” as Patent Owner contends. Id. Thus, we find unavailing Patent Owner’s contention that Buer does not disclose the “enabled” limitation because, in Buer, “no key is provided in exchange for the information.” PO Resp. 33.

“B. Principles of Law A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, “would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of 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 non-obviousness.10 See Graham v.

Petitioner’s contention is supported by Dr. Wolfe’s testimony and is consistent with the teachings of Buer. See Ex. 1003 ¶ 229. Based on the complete record presented, we determine that Petitioner has persuasively shown that Buer teaches “one or more of the integrated RDC and integrated PDK enabling one or more of an application, a function, and a service on one or more of the hybrid device and a device associated with the external RDC,” as recited in claim 1. v.

Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. at 32 (citing Ex. 2002, 26)) to support its contention that the District Court construed the term “enabling,” as we determined in the Decision to Institute, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Dec.

Thus, as we previously explained, by determining that “hybrid device” is not indefinite, the District Court did not construe the term “enabling.” Id.; see also Ex. 2002, 26. Accordingly, nothing in the Memorandum provides a construction of “enabling” as Patent Owner contends. Id. Thus, we find unavailing Patent Owner’s contention that “nowhere does Dua teach or describe . . . providing an access key in exchange for information held locally in the PDK’s service blocks.” PO Resp. 33.

“We find Patent Owner’s arguments unavailing, as they rely on Patent Owner’s arguments that “the specification defines ‘local, secured information’ as information stored within a service block of a PDK and unlocked with a corresponding access key provided to the PDK” (PO Resp. 30), with which, as discussed above, we do not agree. Dua discloses an “RFID Tag-Reader Module” which includes “Tag Memory 322” that may be tamper resistant. See Ex. 1004 ¶¶ 105, 109. Thus, we find persuasive Petitioner’s reliance on Dua’s Tag Memory 322, which locally stores information in a tamper-resistant manner, for teaching an integrated, secure memory for storing information locally, wherein the information is secured.

“Petitioner contends that “it would have been obvious to a [person of ordinary skill in the art] to incorporate the age verification method of Robinson in Burger so that Burger’s system can be used by businesses interested in conducting transactions that require age-verification.” Pet. 93. Petitioner argues that it would have been predictable to include Robinson’s age-verification feature in Burger’s system in light of Robinson’s explanation that merchants and their employees face penalties if they sell age-restricted goods (e.g., alcohol or tobacco) to underage individuals. Id. at 94–95 (citing Ex. 1006 ¶ 5; Ex. 1003 ¶¶ 79–80).

“We find that, after Burger’s network server 114 authenticates a user’s pocket vault ID, the user is granted access to pocket vault 102 and can select a transaction from a displayed menu, including use of a credit card. subsequent access to that credit card information, either by displaying it or through token 102a, is because network server 114 sent a communication to pocket vault 102 indicating that it successfully authenticated the pocket vault. Ex. 1003 ¶ 115. This is the obvious inference a skilled artisan would have drawn from Burger’s description of authenticating the pocket vault and subsequently allowing credit card information to be used. Thus, we find that, in this example, the operator of network server 114 is a third party that operates a trusted authority, the principle parties to the transaction are the user of pocket vault 102 and the retailer, and a message from network server 114 to pocket vault 102 allowing the credit card to be used (displayed or encoded in the token) is an access message allowing the user access to the application (file with credit card information).

“We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012).

Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

“Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

“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.

- 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.
