“appear to be that Patent Owner specifies that the POSA’s knowledge and experience may include optical sensors and that the POSA may have a degree emphasizing software. We do not deem these differences material, particularly because the optical sensors and technologies at issue are those used in physiological monitoring technologies and both parties agree that the POSA would have a working knowledge of physiological monitoring technologies. Ex. 1003 ¶ 24; PO Resp. 11. We find the additional specificity of Patent Owner’s definition to be helpful. In addition, Patent Owner’s definition appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’507 patent. Accordingly, we adopt Patent Owner’s proposed definition of the person of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Our inability to find a teaching of averaging in Mendelson is consistent with the testimony of Drs. Kenny and Duckworth. Dr. Kenny testifies that “there is simply no disclosure in Mendelson itself of any summing or averaging of collected signals.” Ex. 1083 ¶ 23. And in his deposition, Dr. Duckworth was unable to identify any express disclosure of averaging in Mendelson. See Ex. 1087, 103:9–114:11 (confirming that certain aspects of his declaration testimony relating to averaging of signals are not discussed in Mendelson).

“witnesses cannot agree on a numerical definition of “high pressure.” Mr. Marscher says high pressure is between 5,000 psi and 15,000 psi (see Ex. 1030, 111:1–112:3), whereas Mr. Schaaf says high pressure is between 8,000 psi and 12,000 psi and specifically disagrees with Mr. Marscher’s testimony that high pressure can be below 8,000 psi (see Ex. 1031, 43:6–44:13). Although there are overlapping values in the witness testimony, we agree with Petitioner that the testimony does not evidence clear boundaries for how an ordinarily skilled artisan would interpret “high pressure.” See Mot. Sur-reply 6 (citing Nautilus, Inc. v. Biosig Instruments, Inc., 572 U.S. 898, 901–02 (2014); Interval Licensing, 766 F.3d at 1371). Thus, the testimony of Patent Owner’s own witnesses is contrary to Patent Owner’s position that an ordinarily skilled artisan would have understood the meaning of “high pressure.” Furthermore, neither Mr. Marscher nor Mr. Schaaf cites any objective evidence to support their respective notions of what “high pressure” might be, in the context of hydraulic fracturing. For example, neither witness cites to any published industry standards to support their respective opinions. This lack of objective evidentiary support weakens the persuasiveness of both witness’s testimony on this issue, especially because their opinions conflict with each other. We are instead persuaded by the testimony of Petitioner’s witness, Dr. Durham, who testifies that “[t]here is [no] general consensus about the precise boundaries of the term ‘high pressure,’ and different engineers can reasonably come to different conclusions as to the meaning of the term absent further guideposts.” Ex. 1036 ¶ 17; see also id. ¶ 19 (“There is no universally accepted definition of ‘high pressure.’”). Dr. Durham further testifies that “what might be sufficiently ‘high’ pressure for one fracturing application and according to one [person of ordinary skill in the art] may be not ‘high’ enough in another fracturing application and to another [such person].” Id. ¶ 18; see also id. ¶ 19 (“Merely stating that a pump fractures a formation says little to nothing about whether that pump should be deemed ‘high pressure’ or ‘not high pressure.’”).” slip op. at 30

“The intrinsic record does not “provide objective boundaries for those of skill in the art” to determine whether a given pressure is “high pressure” as recited in the proposed substitute claims. See Interval Licensing, 766 F.3d at 1370–71. Nor does the intrinsic record provide guidance to clarify the meaning of “high pressure.” As noted above, the ’732 patent refers only to “high pressure” without qualification or explanation as to how “high pressure” is determined. The prosecution history does not address “high pressure” in any meaningful way and, therefore, also fails to explain what pressures are “high” pressures. See generally Ex. 1003. Thus, the intrinsic record does not explain adequately what pressure(s) qualify as “high pressure,” nor differentiate “high pressure” from other pressures at which hydraulic fracturing can be performed.” slip op. at 27

“skilled artisan to have its “ordinary and customary meaning[],” allegedly “a stream of data bytes that can be read and written (among other common operations).” PO Resp. 3. But as noted by Petitioner (Pet. Reply 3–4), the only intrinsic evidence cited by Patent Owner does not support its proposed construction in the context of the ’613 patent; rather, such evidence favors Petitioner. See PO Resp. 4 (citing Ex. 1001, 2:35–45 (a “‘file is accessed via the file descriptor’”), 2:46–3:7 (“‘the system calls that access files via file descriptors do not distinguish between a file on media and a communication channel’”)); see also PO Resp. 7 (“It is undisputed that file descriptors were conventionally ‘associated with’ files stored on media, communication channels, and even hardware devices.” (emphasis added)). Patent Owner also cites extrinsic evidence, namely, Dunsmuir (Ex. 1007), to support its proposed construction: “Conceptually, a file consists of a stream of data bytes followed by a logical end-of-file. … Because UNIX file I/O is performed through a uniform file interface, a program that can read and write files can read and write anything.” PO Resp. 4 (quoting Ex. 1007, 22). But as noted by Petitioner (Pet. Reply 4–6), Patent Owner does not explain why this “conceptual” meaning set forth in the generic context of programming interfaces in a UNIX operating system would apply in the specific context of the ’613 patent. See Pet. Reply 4 (“[Patent Owner’s] proposed construction is problematic because it is inconsistent with the specification of the ’613 patent.”). Patent Owner also does not explain what “among other common operations” means in the context of its own proposed construction. For the foregoing reasons, and those discussed below, we agree with Petitioner’s proposed construction of “file.” First, the claims of the ’613 patent support Petitioner’s proposed construction. For example, claim 1 recites that a “file” is accessed via a file descriptor. Ex. 1001, 14:55. Claim 5 recites a file descriptor being associated with “a communication channel” and determining with what file type the file descriptor is associated. Ex. 1001, 15:44–57. Together, these limitations show that a “file” is an entity assessed via a file descriptor, and such an entity includes, for example, a communication channel (i.e., per these claims, a communication channel is a type of file associated with a file descriptor). We find nothing in the claims, and Patent Owner does not direct us to anything in the claims, that supports limiting the term “file” only to a “stream of data bytes that can be read and written.”” slip op. at 20

“In our Institution Decision, we credited the foregoing and related testimony of Dr. Greenspun (Ex. 1002 ¶¶ 96–98), and noted that Patent Owner at that stage of the proceeding had not offered any evidence to rebut Dr. Greenspun’s testimony. Dec. 30–31. Despite that, as highlighted by Petitioner, Patent Owner still offers no evidence to rebut Dr. Greenspun’s testimony in this regard. See Pet. Reply 16 (“But in arguing all these [above arguments], [Petitioner] presents no rebuttal evidence—neither a deposition testimony of Dr. Greenspun, nor a rebuttal testimony by its own expert, nor any other evidence.”); see generally PO Resp. Instead, Patent Owner merely declares Dr. Greenspun’s testimony “conclusory” and tainted by “vague leap[s]” (see, e.g., PO Resp. 14), but yet makes such accusations against a technical declarant with nothing but attorney-argument. Regardless, for the same reasons given by Petitioner (see Pet. Reply 16–18), we disagree with Patent Owner and continue to credit Dr. Greenspun’s technical testimony as to the subject limitation. See Pet. Reply 16–18 (Petitioner explaining why “[Patent Owner’s] attorney argument is wrong”.). As noted above, Patent Owner variously argues Dukach does not disclose “storing” of the indicator at issue in this limitation. See generally PO Resp. 7–17. To summarize, we disagree with Patent Owner, and as explained above, are persuaded by Petitioner’s evidence, including the unrebutted testimony of Dr. Greenspun, that Dukach discloses storing information that points to a file type associated with a file descriptor. First, we are persuaded that, in Dukach, the presence or absence of a file descriptor’s number in the list of monitored file descriptors constitutes information that points to a file type associated with the file descriptor. See Pet. 37–40 (citing, inter alia, Ex. 1005, 11:5–40; Ex. 1002 ¶ 96; Ex. 1001, 11:12–42). Second, we also are persuaded that, in Dukach, the list of monitored file descriptors “needs to be maintained in memory such that it can be used by software to check an at-issue file descriptor’s presence or absence in the list,” which constitutes storing the indicator. Pet. Reply 16– 17 (quoting Ex. 1002 ¶ 97); see Pet. 40 (citing Ex. 1002 ¶ 97). Finally, even if Patent Owner were correct that Dukach does not disclose a particular embodiment in the ’613 patent (see, e.g., PO Resp. 15 (discussing an embodiment “only applicable for binary file types”)), the issue before us is not whether Dukach indeed discloses such an embodiment, but rather whether Dukach discloses the invention recited, for example, in claim 1, given the breadth (scope) of the limitations defining that invention.” slip op. at 37

“Turning now to obviousness, Petitioner identified disclosure within Kurgonov-262 and Chakrabarti which teaches or suggests the limitations of claim 1. Pet. 11–21. Furthermore, Petitioner identified multiple reasons that would have prompted the skilled artisan to combine the teachings of Kurganov-262 and Chakrabarti to arrive at the subject matter of claim 1. Id. at 21–22. Because Patent Owner focused its arguments solely on the issue of whether Kurganov-262 is prior art, Petitioner’s assertions regarding the substantive teachings of Kurganov-262 and Chakrabarti remain unrebutted on the complete record.

The Federal Circuit explained, “[w]hen claim language has as plain a meaning on an issue as the language does here, leaving no genuine uncertainties on interpretive questions relevant to the case, it is particularly difficult to conclude that the specification reasonably supports a different meaning. The specification plays a more limited role than in the common situation where claim terms are uncertain in meaning in relevant respects.” Id. at 1361. Accordingly, the Federal Circuit construed the limitation “is connected to the computer network” as “is connected to the computer network at the time the query is transmitted to the server.” Id. at 1363.” slip op. at 11

“and NetBIOS fail to determine whether a computer or process is connected to the computer network. PO Resp. 35, 49–51. In view of our construction of this claim limitation, we agree with Patent Owner. Microsoft Manual discloses that once a computer is registered with the WINS server (which is a NetBIOS Name Server (NBNS)) as active and on-line, the WINS server maintains a database of names and addresses as active and on-line by (1) releasing names once a computer is shut down properly and (2) requiring a renewal time period in which a computer must reregister. Ex. 1012, 62– 63, 68–69. Microsoft Manual discloses that in response to User Datagram Protocol (UDP) name queries, “a mapping in the database does not ensure that the related device is currently running.” Id. at 68. Microsoft Manual further explains that a “local WINS database should periodically be cleared of released entries and old entries that were registered at another WINS server but did not get removed from this WINS database for some reason.” Id. at 150. In other words, Microsoft Manual discloses that the WINS database may include entries of computers that are not currently connected to the WINS network. Accordingly, a query to as to whether a second process “is connected to the computer network” in Microsoft Manual will not determine whether the second process is connected to the WINS network at the time that the query is transmitted to the server. As discussed above in our claim construction analysis above (see Section I.E.1), a query as to whether a process “is connected to a computer network” or has an “on-line” status asks “whether the device ‘is’ connected, not whether it was connected or whether it is still registered as being connected even if that registration information is no longer accurate. It is not a reasonable interpretation of the claim language . . . to say that it is satisfied by a query that asks only for registration information, regardless of its current accuracy.” Straight Path, 806 F.3d at 1360. Microsoft Manual discloses that the WINS server has information that a process “was” connected to the computer network, and that information may no longer be accurate. See Ex. 1012, 68, 150. As such, we determine that Microsoft Manual does not disclose the claimed “is connected to the computer network,” “on-line status,” or “is accessible,” as construed herein. Similarly, NetBIOS discloses a registration process for resources or nodes to receive a unique name by registering a name. Ex. 1014, 379. During a name query (discovery), a datagram is sent requesting the name and address of another resource. Id. at 396. The NBNS maintains a database of resource names through explicit name deletion, where the node specifies a deletion function and implicit name deletion, which occurs when a node ceases operation. Id. at 379. NetBIOS explains that implicit name deletion “is a frequent occurrence.” Id. Implicit name deletion is managed by assigning nodes a specified lifetime for registered names, where a name is silently released if a node fails to refresh the registered name before the lifetime expires. Id. NetBIOS further discloses a mechanism where the NBNS may correct the information stored after an incorrect response is provided to a requesting node. See id. at 409. However, similar to Microsoft Manual, NetBIOS discloses that the information stored by the NBNS may be incorrect, and, therefore, will not determine whether a second process is connected to the computer network at the time that the query is transmitted to the server. Therefore, NetBIOS also does not disclose the claimed “is connected to the computer network,” “on-line status,” or “is accessible.” Given that the combination of Microsoft Manual and NetBIOS fails to teach or suggest the claims as construed, we need not reach the remaining arguments presented by Petitioner and Patent Owner.” slip op. at 19

“Petitioner contends that “WINS is an implementation of NetBIOS” and, therefore, Petitioner contends that “one having skill in the art would have known about and been motivated to combine Microsoft Manual with NetBIOS.” Id. at 34 (citing 67 Ex. 1004 ¶¶ 88–89). We are persuaded by Petitioner that the combination is reasonable because Microsoft Manual demonstrates that Microsoft TCP/IP has combined the elements of NetBIOS and Microsoft Manual in the same manner in which Petitioner proposes to combine NetBIOS and Microsoft Manual. See 67 Ex. 1012, 3, 11. Microsoft Manual discloses that Microsoft TCP/IP for Windows NT provides support for application interfaces, including NetBIOS for establishing logical names and sessions on the network. Id. at 11. Microsoft Manual describes that “[w]hen WINS servers are in place on the network, NetBIOS over TCP/IP resolves names on a client computer by communication with the WINS server.” 67 Pet. 34 (quoting 67 Ex. 1012, 62). We are persuaded that Microsoft TCP/IP for Windows NT utilizes NetBIOS features for name resolution, as disclosed by Microsoft Manual, and a person with ordinary skill in the art would have readily combined the disclosures of Microsoft Manual and Microsoft Manual.” slip op. at 25

“A petition for inter partes review must identify “all real parties in interest.” 35 U.S.C. § 312(a)(2). The Office Patent Trial Practice Guide provides guidance regarding factors to consider in determining whether a party is a real party in interest. 77 Fed. Reg. 48,756, 48,759–60 (Aug. 14, 2012). Considerations may include whether a non-party “funds and directs and controls” an IPR petition or proceeding. Id. at 48,760. Additional relevant factors include: the non-party’s relationship with the petitioner; the non-party’s relationship to the petition itself, including the nature or degree of involvement in the filing; and the nature of the entity filing the petition. Id. Generally, a party does not become a “real party-in-interest” merely through association with another party in an unrelated endeavor. Id. A party also is not considered a real party in interest in an inter partes review solely because it is a joint defendant with a petitioner in a patent infringement suit or is part of a joint defense group with a petitioner in the suit. Id. Whether a party who is not a named participant in a given proceeding is a “real party-in-interest” to that proceeding “is a highly fact-dependent question.” Id. at 48,759. There is no “bright line test.” Id. Courts invoke the term “real party-in-interest” to describe relationships and considerations sufficient to justify applying conventional principles of estoppel and preclusion. Id. Here, even assuming this contention is timely, Patent Owner has failed to provide any evidence, besides the mere fact that the other parties are co-defendants in a lawsuit or alleged infringers, to support the contention that Petitioner has failed to name all of the real parties in interest. That one fact, without any further proof of control or involvement by these parties in this proceeding, is insufficient to establish that Petitioner has failed to name” slip op. at 11

A Patent Owner Response is not the proper vehicle to seek to exclude testimony. See 37 C.F.R. § 42.64(c). Moreover, even if it were the proper vehicle, we are not persuaded that the alleged “falsehood” that Patent Owner identified—listing patent applications, which are clearly identified as such, under a heading titled “Patents”—is, in any way, misleading.

- Skill levelSkill level petitioner adoptedDecided for petitioner
“i. Level of Ordinary Skill in the Art Neither party puts forward a succinct definition of the level of ordinary skill in the art. Petitioner’s declarant, however, has put forward a detailed discussion of various references dated before April 20064 (the date Patent Owner now alleges is the priority date) related to subject matter of the ’990 patent. See Ex. 1005 ¶¶ 20–74, 94–99. We have reviewed that discussion and the references cited in those paragraphs. We have found it accurately reflects the teachings of the references. Moreover, we agree with Petitioner’s declarant that the references are analogous to the claimed invention, and, as such, represent the level of skill in the relevant art at the time of the invention. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (finding that the Board did not err in concluding that the level of ordinary skill was best determined by the references of record); In re Oelrich, 579 F.2d 86, 91(CCPA 1978) (“[T]he PTO usually must evaluate . . . the level of ordinary skill solely on the cold words of the literature.”); see 4 We accept this date as the priority date only for the sake of argument. also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“We agree with Petitioner and find, based on the Patent Owner’s own arguments, that these terms improperly broaden the scope of the claims. As Patent Owner explains, the added language is broad enough to include the removed items, and is intended to reflect the entire genus of “monitoring equipment” and “communications devices” that “are capable of communication and capable of receiving signals.” Mot. to Amend 4, 5. Thus, the claim has been broadened to not only include the listed species that have been removed, but anything falling within the claimed genus. Accordingly, we find that this amendment impermissibly broadens the claim. As for the second change in the claim language, we find that Patent Owner has failed to show why removal of the entire passage “wherein, the communication device receives a signal via any of one or more products listed in any of the plurality of product grouping categories,” would not impermissibly broaden the scope of claim 154. The deletion of this limitation necessarily broadens the claim in that limitation’s aspect. See In re Clement, 131 F.3d 1464, 1468 (Fed. Cir. 1997) (“For example, a reissue claim that deletes a limitation or element from the patent claims is broader in that limitation’s aspect.”). Given that Patent Owner has entirely deleted this limitation and Patent Owner bears the burden of showing entitlement to the amendment, it was incumbent on Patent Owner to explain why removing this entire passage from claim 154 would not broaden the scope of the claim. See In re Bennett, 766 F.2d 524, 526 (Fed. Cir. 1985) (en banc) (“[A] claim is broadened if it is broader in any respect than the original claim, even though it may be narrowed in other respects.”).” slip op. at 17

“1. the cleavable linker and the protecting group are cleavable under identical conditions Proposed substitute claim 20 recites, inter alia, “a base that is linked to a detectable label via a cleavable linker,” a “protecting group attached via the 3' oxygen atom” of the nucleotide, and a step of “removing the label and the protecting group of the nucleotide . . . under a single set of chemical cleavage conditions.” Mot. 2 (emphasis added). These limitations are similar to those present in original claim 1, which we construed in our Decision on Institution. Specifically, we construed removal of the label and the protecting group under a single set of conditions “to mean what its plain language indicates: removal of the label and the protecting group under a single set of conditions.” Dec. 6. Neither of the parties contested this construction subsequent to institution, and we discern no reason to modify our initial construction for the purposes of this decision. Proposed claim 20 also requires that the cleavable linker comprise a disulfide linkage, but does not specify the protecting group. Thus, “a single set of chemical cleavage conditions,” under the broadest reasonable interpretation standard, limits the structure of the protecting group to one which can be cleaved under the same conditions as a disulfide linkage, but does not require a specific structure, such as a disulfide linkage.” slip op. at 8

“Illumina was essentially 100%. This is a significant and unexpected improvement over the disulfide cleavages of Ruby (~86%) and Herman (87%).” Ex. 2004 ¶ 84. There is no testimony, however, that the stated results were due to the claimed nucleotide rather than the reducing agent. While Dr. Romesberg refers to the “disulfide cleavage yield” as being unexpected, he does not testify that this yield was attributable to the claimed nucleotide configuration, rather than the reducing agent which performs the disulfide bond cleavage. Illumina has not distinguished the Vermaas results from the prior art by showing that the nucleotide is responsible for the disulfide yield, rather than it being a property of the disulfide bond and the yield being “the mere recognition” of the bond’s “latent properties,” which “does not render nonobvious an otherwise known invention.” Baxter, 952 F.2d at 392; In re Geisler, 116 F.3d 1465, 1468 (Fed.
