“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

“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

Even if the Specification describes embodiments in which the user can begin in a prone position and then transition to a kneeling or standing position, as Patent Owner points out (see Prelim.

“1. “wherein a user can be disposed on the top surface of the flotation device in a prone, kneeling, or standing position” With respect to the claim term “wherein a user can be disposed on the top surface of the flotation device in a prone, kneeling, or standing position,” Patent Owner points to passages of the Specification, arguing that all three positions are possible. Prelim. Resp. 19–21 (citing Ex. 1001, Abstr., 4:13–17, 4:33–40; Ex. 2006 ¶ 18). We do not agree with Patent’s Owner proposed construction because even if the Specification discloses that all three positions are possible, that is not what the plain language of the claim requires. Claim 1 recites “or,” which means that a user can be disposed on the top surface of the flotation device in any one of the three positions. See, e.g., SkinMedica, Inc. v.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner
“awake state” Claim 24 recites, in part, “to determine whether breathing patterns indicate an asleep state or an awake state.” Ex. 1001, 11:36–12:7; see also id. at 9:49–64 (claim 1 reciting “between an awake state and an asleep state”), 10:42–56 (claim 11 reciting “at least one of an awake state or an asleep state”). In regard to its allegations of obviousness, Petitioner’s arguments suggest an “awake state” ordinarily means when a patient is not asleep. Pet. 36–37, 42. By contrast, with regard to its allegations of anticipation, Petitioner argues that under Patent Owner’s “implied construction of ‘an awake state’ based on [Patent Owner’s] infringement allegations” in district court, “the patient is in an awake state when there is an absence of obstructions or other breathing patterns indicative of sleep.” Id. at 68–70 (citing, e.g., Ex. 1018 ¶¶ 2, 158, 159). Petitioner provides no further support for this “implied construction” purportedly taken from Patent Owner’s district court allegations. Id. Dr. Kirkness, in support of Petitioner, applied the plain meaning of all terms and phrases. See, e.g., Ex. 1003 ¶ 80. In regard to supporting Petitioner’s allegations of anticipation, Dr. Kirkness merely assumed Patent Owner’s purported district court claim construction “position to be true.” Ex. 1003 ¶ 253. In this proceeding Patent Owner does not propose an express meaning for “awake state.” See PO Resp. 29–33. More generally, Patent Owner states that the ’539 patent “teaches how to distinguish between an awake state and an asleep state.” Id. at 8. From the arguments of the Parties, we discern no dispute in this proceeding that a plain and ordinary meaning of an “awake state” is a state in which a patient is not asleep. See Ex. 1001, 3:1–5 (distinguishing between “a wake state” and “a sleep state”), 7:22–24 (describing an embodiment with a processing arrangement that “may determine whether the patient is in a sleep state or a wake state based on the breathing pattern”).8 We apply the plain and ordinary meaning of “awake state” in this proceeding and further determine that Petitioner has not shown by a preponderance of the evidence that an awake state means “an absence of obstructions or other breathing patterns indicative of sleep.” slip op. at 15

“Next, we turn to the Specification. “While we read claims in view of the specification . . . we do not read limitations from the embodiments in the specification into the claims.” Hill-Rom Servs., 755 F. 3d at 1371 (citation omitted). “We depart from the plain and ordinary meaning of claim terms based on the specification in only two instances: lexicography and disavowal.” Id. In order for a patentee to act as its own lexicographer, the “patentee must ‘clearly set forth a definition of the disputed claim term other than its plain and ordinary meaning’” and “must ‘clearly express an intent’ to redefine the terms.” Bradium Tech., 923 F. 3d at 1044. In this case, Patent Owner does not argue that it disavowed the full scope of the plain and ordinary meaning of claim 24, nor does Patent Owner argue that it explicitly defined “analyzing the breathing patterns” in the Specification. See, e.g., PO Resp. 29–32. We determine that there is no disavowal nor any explicit lexicographic definition of “analyzing the breathing patterns” in the Specification. Patent Owner instead relies on an “implied lexicography” theory as to why we should construe the phrase as Patent Owner proposes. PO Sur-reply 2, 6–7 (citing, inter alia, AstraZeneca AB v. Mut.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“We disagree with Patent Owner’s arguments—that Petitioner fails to show any motivation to combine and that Sullivan460 is not enabled— merely because Dr. Kirkness indicated in a deposition that he did not know how a preset level is calculated from a sentence in Sullivan460. As Petitioner explains, enablement “is not a requirement to prove invalidity under §103.” Amgen, 314 F.3d at 1357 (under §103, “a reference need not be enabled; it qualifies as a prior art, regardless, for whatever is disclosed therein”). Moreover, we agree with Petitioner that the Challenged Claims do not require any preset level for a flow rate, and a person of ordinary skill “would have understood that a preset level is established from previously-acquired data or data from a previous window of time, such as an average level, for example, as taught in Sullivan995.” Pet. Reply 15 (citing Ex. 2014, 38:2–16; Ex. 1005, 17:3–27, Fig. 12). Patent Owner responds that Petitioner’s assertion is unsupported, and that “Petitioner is obligated to address this challenge, and failed to do so.” PO Sur-reply 18–19 (citing In re Morsa, 713 F.3d 104, 110 (Fed. Cir. 2013)). We find Petitioner’s arguments persuasive because they are supported by the asserted references. Sullivan995 discloses that the computing system may “calculate control values of patterns for each patient based on moving average values or such values or patterns will be pre-programmed into the computing system.” Ex. 1005, 17:14–18. According to Sullivan995, when “signals deviate from predetermined values or patterns the computer system generates a signal which is sent to the feedback speed controller on the blower motor.” Id. at 17:19–22. Based on this disclosure, and given that Sullivan460 incorporates Sullivan995 by reference, we agree with Petitioner that Sullivan460’s disclosure of detecting that the flow rate has fallen below a preset level would have informed a person of ordinary skill that this level was predetermined, so that “the controller 100 activates the nCPAP apparatus 90 to supply air to the patient 30 at a pressure which ameliorates or eliminates the upper airway flow limitation.”16 Ex. 1006, 10:17–21.” slip op. at 50

“disseminated to the interested public, ‘public accessibility’ has been called the touch-stone in determining whether a reference constitutes a ‘printed publication’ . . . .” Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347, 1356 (Fed. Cir. 2018) (quoting In re Hall, 781 F.2d 897, 898–99 (Fed. Cir. 1986)). A reference is considered “publicly accessible” if it was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it.” Id. at 1355–56 (citing In re Wyer, 655 F.2d 221, 226 (CCPA 1981)). Petitioner treats this requirement as having two aspects, namely (1) whether a person of ordinary skill could reasonably have found RemoteCentral.com and (2) whether such a skilled artisan could reasonably have found RadioShack on RemoteCentral.com. Reply 8–13; see also Tr. 33:25–34:8 (Patent Owner asserting that there are two aspects to the analysis on public accessibility: “The first is whether a [person of ordinary skill in the art] would have known to arrive at the website containing the prior art reference. The second one is . . . , [a]ssuming the [person of ordinary skill in the art] would have done so, would the [person of ordinary skill in the art], exercising reasonable diligence, have located the prior art reference on the site?

Specifically, after a petitioner has presented “evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent,” such that trial is instituted, “some limited opportunities exist for the petitioner to present new evidence later.” Hulu at 13–14. These “limited opportunities” include “in a reply to the patent owner response,” provided that the additional evidence is “responsive to the prior briefing” and provided that the additional evidence does not require “completely reopen[ing] the record, by, for example, changing theories after filing a petition.” Id. at 14–15. Although Patent Owner contends that “[t]his is not an example of permissible rebuttal evidence, but rather a belated attempt to fill a gap in the evidence in the Petition,” we disagree. See Sur-reply 6. Rather, the 7 Patent Owner appears to refer incorrectly to Exhibit 1040 instead of Exhibit 1041 when identifying “articles allegedly referring to RemoteCentral.com.” See Sur-reply 5–6. progression within the instant proceeding comports well with the Hulu framework. During the preliminary proceeding, Petitioner came forth with “evidence sufficient to establish a reasonable likelihood that [RadioShack] was publicly accessible before the critical date of the challenged patent,” just as Hulu demands. Hulu at 13; Inst. Dec. 23 (“[W]e determine that Petitioner’s showing regarding public accessibility of RadioShack is sufficient under the standard we apply at this stage of the proceeding.”). Patent Owner challenges RadioShack’s status as a printed publication in its Response, just as Hulu contemplates. Hulu at 15; PO Resp. 28–41. And Petitioner submits additional evidence that replies to that challenge without changing its theory that RadioShack qualifies as a printed publication by virtue of its accessibility on the RemoteCentral.com web site and in light of date indicia on RadioShack itself.8 See Hulu at 15–16; Reply 7–13. Moreover, in determining that Petitioner’s additional evidence directed at RemoteCentral.com is properly considered, we are further mindful of the Federal Circuit’s endorsement that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1830–81 (Fed. 8 In its Reply, Petitioner also relies on evidence of publication of RadioShack on Radio Shack’s own public website and on “a third location,” hifi-remote.com. Reply 14. As we discuss below, we determine that the presence of RadioShack on RemoteCentral.com is sufficient to qualify RadioShack as a printed publication. We therefore do not reach the issue of whether presence on either the Radio Shack web site or on hifi-remote.com is an improper new theory raised by Petitioner in its Reply. See Tr. 8:13– 9:23 (Petitioner discussing whether reliance on hifi-remote.com presents a different theory than set forth in the Petition). Cir. 2018); see also Vidstream LLC v.

We conclude that the Board acted appropriately, for the Board permitted both sides to provide evidence concerning the reference date of the Bradford book, in pursuit of the correct answer.”).

“On this record, we are sufficiently persuaded by Petitioner’s argument that a person of ordinary skill in the art would have combined the teachings of Perego and JESD79-2. As Petitioner correctly points out (Pet. 32), Perego discloses using DDR2 memory devices. Ex. 1071, 10:56–59 (“Other memory devices may be implemented on module 400, for example, Double Data Rate 2 (DDR2) DRAM devices and Synchronous DRAM (SDRAM) devices.”). On this record, we find this teaching to use DDR2 sufficiently supports Petitioner’s rationale to combine Perego with JESD79-2, which is the JEDEC DDR2 SDRAM Specification. Ex. 1064, 1 (cover page); see also Prelim. Resp. 44 (parenthetical noting that “JESD79-2 is a specification for individual DDR2 SDRAMs”). As to Patent Owner’s argument that Rambus memories lack a chip select network (Prelim. Resp. 25–26), the reference on which Patent Owner relies discloses that chip select information is still used in the particular Rambus devices described. See Ex. 1069, 11 (“[I]n the Rambus bus organization, all addresses, commands, data, and chip-select information are sent on the same bus lines.”), 12 (“[T]he example system uses a total of nine (9) lines to carry all necessary information, including addresses, commands, chip-select information, and data.”).

“Claim 21 is method claim and recites similar structure in the preamble. Petitioner cites this claim language in support of its position that a rank can have just one memory device. Pet. 28 (citing Ex. 1001, 37:32–38 (portion of claim reproduced above)). On this record, we determine that the claim language supports Petitioner’s position. Claim 1 recites “at least one first memory integrated circuit in the first rank and at least one second memory integrated circuit in the second rank.” This language is met if there is one memory integrated circuit in each rank because “at least one” includes just one. On this record, we disagree with Patent Owner’s argument that this claim language “do[es] not define the term ‘rank’” but, rather, “provide[s] context that a claimed ‘buffer’ can be, but need not be, coupled to multiple memory devices in the rank.” See Prelim. Resp. 9–10. Claim 1 recites “a buffer coupled between the at least one first memory integrated circuit and the memory bus, and between the at least one second memory integrated circuit and the memory bus,” and it further recites “enabl[ing] communication of the first data burst between the at least one first memory integrated circuit and the memory controller through the buffer” and “enabl[ing] communication of the second data burst between the at least one second memory integrated circuit and the memory controller through the buffer.” If there is only one memory device in each rank, then the buffer will only be connected to the one memory device in each rank.

Resp. 44. We disagree. Petitioner presents detailed testimony from Dr. Wolfe explaining how Perego’s registered data transfers would have introduced delay. In particular, Dr. Wolfe, citing Perego’s disclosures of data latches and an internal clock to generate synchronizing clock signals (Ex. 1071, 12:65–13:5, 17:61–63, Fig. C), provides the following testimony: A Skilled Artisan would have understood from these disclosures that Perego’s latching of the data signals and the use of internal synchronizing clock signals adds a predetermined amount of time delay for each data transfer through the buffer because the output of the latch needs to be in synchronization with an internal clock. A Skilled Artisan would have understood that such registering of the data signals would require the addition of a fixed time delay, such as one clock cycle, for each registered data transfer through the circuitry with respect to the actual operational CAS latency of each of the plurality of memory integrated circuits. Ex. 1003 ¶ 360. Dr. Wolfe further explains how Perego’s “latching delays in the buffer device of Perego increase the overall CAS latency of the memory module compared to the CAS latency of the memory devices.” Ex. 1003 ¶ 362 (citing Ex. 1071, 12:65–13:5, 18:65–19:3, Figs. 5B, 5C).
