“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

“Neither party contends that any claim terms require an express construction to resolve the present controversy. Pet. 8 (“For purposes of this Petition only, Petitioner does not believe any terms require a formal construction.”); see generally Prelim. Resp. Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id. Petitioner contends that, “[a]pplying the correct meaning of the term, Walton’s MIMO receiver does not necessarily comprise a MUD module.” Id. Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied.

“We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1. See, e.g., 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if — (3) the petition identifies, in writing and with particularity, . . . the evidence that supports the ground for the challenge to each claim . . . .”). First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89. But, as noted above, Jin does not disclose an element referred to as a “pilot parameter” and it is not clear what element Dr. Min intended to identify in Jin.8” slip op. at 18

“prosecution history sheds substantial light on how the applicants understood the disputed claim language. As set forth above, in response to rejections based on Candelore-II, the applicants raised two primary arguments. First, the applicants argued that Candelore-II “does not . . . appear to disclose partial encryption of encoded frames of video by encrypting at least one block of data within the partially encrypted frame so that only a portion of the encoded frame is encrypted.” Ex. 1103, 250. Second, and importantly, the applicants argued that Candelore-II’s failure to disclose partial encryption of encoded frames of video “is highlighted by the Candelore patent’s failure to disclose DRM information including ‘an offset value that points to the start of an encrypted block within an encoded frame as recited in claim 1.” Id. at 251 (first emphasis added). Critically, the very next sentence begins with the word instead, and states, “[i]nstead, the Candelore patent discloses pointers that point to the location of encrypted portions of the video data relative to the file.” Id. (emphases added). These two sentences from the applicants’ argument directly contrast the recited “offset value” language with Candelore-II’s disclosure. Specifically, the applicants sought to distinguish Candelore-II because its pointers are relative to the file. We find that by contrasting Candelore-II’s pointers, the applicants “ma[d]e clear that the invention does not include a particular feature”— pointers that are relative to the file. GE Lighting Solutions, LLC v. AgiLight, Inc., 750 F.3d 1304, 1309 (Fed. Cir. 2014). And, we also find that the applicants’ arguments constitute a “clear and unmistakable disclaimer” of an offset value that points to the start of an encrypted block within an encoded frame, where the offset value is relative to the file. Thorner v. Sony Computer Ent. Am. LLC, 669 F.3d 1362, 1366–67 (Fed. Cir. 2012). Although we agree with Petitioner that the applicants “never raised a distinction between offset values ‘relative to a file’ and offset values ‘relative to a frame’ at any point during prosecution,” we do not agree with Petitioner that the applicants “never said that offset values relative to a file are excluded from the scope of the claim.” Prelim. Reply 10. Rather, we find no other way to interpret the applicants’ arguments. As noted above, the applicants specifically stated that Candelore-II fails to disclose “DRM information including ‘an offset value that points to the start of an encrypted block within an encoded frame’” and then stated that “[i]nstead,” Candelore-II “discloses pointers that point to the location of encrypted portions of the video data relative to the file.” The applicants’ argument specifically identifies the claim language at issue here and specifically says that it is not disclosed because Candelore-II discloses something else instead.11 Accordingly, for these reasons, we find that the applicants disclaimed “pointers that point to the location of encrypted portions of the video data relative to the file.”” slip op. at 23

“regarding the meaning of “an offset value that points to the start of an encrypted block within an encoded frame,” we determine that the applicants disclaimed an offset value that is relative to the file. See supra § II.A.2. On the present record, we find Patent Owner’s argument and evidence persuasive regarding Candelore-II’s disclosure. In particular, Patent Owner identifies the teachings of Candelore-II directed to its pointers, and Candelore-II’s description and Figure 3 support Patent Owner’s argument that Candelore-II’s pointers are relative to the file. See, e.g., Prelim. Resp. 42 (citing Ex. 1106 ¶ 31, Fig. 3). Additionally, Petitioner does not contest Patent Owner’s position that Candelore-II teaches pointers that are relative to the file. See generally Pet.; Prelim. Reply. Further, as applied to the combination, Petitioner does not propose modifying Candelore-II’s pointers such that they are not relative to the file. See, e.g., Pet. 30–36 (discussing motivation and reasonable expectation of success), 41–53 (discussing, inter alia, limitations [1f], [1h], [1i], and [1j]). Accordingly, because Petitioner relies on the same teaching of Candelore-II that was disclaimed from the scope of the claims during prosecution of the ’443 patent, Petitioner has not shown sufficiently on the present record that the combination of Notoya, Matsui, Candelore-I, and Candelore-II teaches or suggests the subject matter of limitation [1j] and, hence, claim 1. d. Independent Claim 7 and Dependent Claims 2, 4, 8, 10, 14, and 16 As noted above, limitation [7j] of independent claim 7 recites the same “offset value” language as limitation [1j] and Petitioner relies on its arguments and evidence directed to limitation [1j] in its discussion of limitation [7j]. See Pet. 72–73 (limitation [7j]). For the same reasons discussed above, we find that the same deficiency regarding claim 1 applies equally to claim 7 and the claims that depend from claim 1 or claim 7— claims 2, 4, 8, 10, 14, and 16. Accordingly, because Petitioner relies on the same teaching of Candelore-II that was disclaimed from the scope of the claims during prosecution, Petitioner has not shown sufficiently on the present record that the combination of Notoya, Matsui, Candelore-I, and Candelore-II teaches or suggests the subject matter of limitation [7j] and, via their dependency from claim 1 or claim 7, the subject matter of dependent claims 2, 4, 8, 10, 14, and 16.” slip op. at 44

“Obviousness Analysis A 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 the subject matter pertains. See 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, primarily: (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 nonobviousness. Graham, 383 U.S. at 17–18.6 Petitioner asserts that claims 1–2, 7–8, 10, 12–13, and 17–18 are unpatentable under § 103 as obvious in view of Paxton and Sutton. See Pet. 6, 18–64. For the reasons described below, we are not persuaded by Petitioner’s argument and evidence.” slip op. at 14

“Petitioner asserts that a person of ordinary skill in the art “had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and approximately 2-3 years of experience in the design or development of telecommunication systems, or the equivalent” and that “[a]dditional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education.” Pet. 13–15 (citing Ex. 1003 ¶¶ 18–20). Patent Owner does not address this issue in the Preliminary Response. As Patent Owner does not dispute Petitioner’s characterization of the level of skill in the art, and because we find it generally consistent with the disclosures of the ’797 patent and the prior art, we adopt it for purposes of this analysis.

“Patent Owner argues that “[t]he plain and ordinary meaning of the terms “determining . . . a first plurality of log entries” and “determining . . . a second plurality of log entries” is “identifying” or “ascertaining” log entries.” Prelim. Resp. 16. Patent Owner also argues that “[t]he terms “provisioning, . . . based on the determined correlation, . . . rules configured to identify the first plurality of packets received by the network device,” and “provisioning, . . . based on the determined correlation, . . . rules configured to identify the second plurality of packets transmitted by the network device” (“provisioning rules”) . . . should be given their plain and ordinary meaning—rules configured to identify packets.” Prelim. Resp. 20. Neither party, however, argues that the prior art arguments presented in the Petition turn on the construction of these terms. Instead, it appears that they are raised as claim construction issues only because Petitioner is challenging the language under Section 112. We will discuss the Section 112 arguments below, but do not see a dispute about the constructions offered by the parties above the makes a difference in the prior art analysis and, therefore, do not construe these terms at this time.

“respect to this limitation for several reasons, including that Petitioner’s “alleged rule generation and provisioning” is responsive to detecting malicious activity, not “based on the determined correlation.” Prelim. Resp. 38. On this record, we agree with Patent Owner. The claims require “generating, by the computing system and based on the determined correlation, one or more rules configured to identify packets received from the first host.” We do not have sufficient argument or evidence to show that one of ordinary skill in the art would have found it obvious to generate these rules “based on” the determined correlation.” slip op. at 16

“c. Summary of Claim 1 In sum, Petitioner does not explain how the edge cache devices contribute or detract from Jungck’s ability to teach or suggest the “entire boundary” and “all traffic” limitations of the challenged claims. The evidence of device 900 and claims of collateral estoppel do not remedy this deficiency. In the absence of such evidence, Petitioner has failed to “identif[y], in writing and with particularity, . . . the evidence that supports the grounds for the challenge.” See Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (“It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’”) (quoting 35 U.S.C. § 312(a)(3)); 37 C.F.R. § 42.104(b). For the reasons above, Petitioner has not shown sufficiently that the combination of Jungck and Wood meets the limitation of “[a] method of filtering packets at a packet security gateway, of a plurality of packet security gateways that collectively provide an entire interface across a boundary of a network protected by the packet security gateway . . . comprising: a first set of packet filtering rules to be applied to all network traffic traversing the boundary.”” slip op. at 24

“We agree with Patent Owner that the Petition’s avoidance of the operation of edge caches when edge caches are important in the processing of traffic flowing across the boundary undermines this ground of the Petition. If Petitioner wished to rely on an embodiment or configuration in which the edge caches were irrelevant, the edge caches were redundant to the edge server, or the edge caches were unnecessary, it was incumbent upon Petitioner to explain sufficiently how and why that was the case. Petitioner was aware of the edge caches because it appears to have omitted all references to them in the Petition yet did not explain why this was done. Additionally, although Petitioner’s declarant does include references to edge caches, its declarant also does not explain sufficiently the relevance of those edge caches. Ex. 1004 ¶¶ 148, 212, 214, 215, 227, 323.

“Patent Owner requests that the preamble of independent claims 1, 8, and 15 be treated as limiting. Prelim. Resp. 16–17. These preambles provide antecedent basis for “packet security gateway,” “boundary,” “network,” and “one or more other networks.” Id. at 16 (citing Ex. 1001, 20:64–21:2, 22:13–18, 23:35–42). The preambles also recite the “plurality of packet security gateways that collectively provide an entire interface across a boundary of a [protected] network,” which is “essential to understand” the “all traffic” limitation in the body of these claims and thus ‘“give life, meaning, and vitality”’ to the claims. Id. (citing Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (citation omitted)). The preambles provide the context for the body of the independent claims by defining the arrangement of the “plurality of packet security gateways” relative to the “boundary” of the protected network and thus the basis for applying “packet filtering rules . . . to all network traffic traversing the boundary.” Id. (citing Ex. 1001, 20:64–21:8). The “entire interface” limitation also was relied on during prosecution of the parent ’437 Patent’s claims to distinguish them from the prior art. Id. at 16–17 (citing Ex. 2008, 254–61; Catalina, 289 F.3d at 808–09). Petitioner does not dispute the preambles are limiting. Pet. 18–21, 37. For, the reasons above, we construe the preambles of independent claims 1, 8, and 15 as limiting. After review of the current record, we conclude that, other than determining the preambles are limiting, no express claim construction is necessary to determine whether to institute review of the challenged claims.
