    “The question of whether the prior art references are in the same field of endeavor is merely a threshold issue that must be satisfied before an obviousness determination can be made. See K-Tec, Inc. v. Vita-Mix, Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either in the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). In other words, once it is determined that the prior art is analogous to the claimed invention, it is then necessary to show that it would have been obvious for the skilled artisan to select and combine the teachings of the prior art in the manner claimed. Thus, we agree with Patent Owner that the Petition needs to set forth specific reasoning as to why an ordinarily skilled artisan would have been motivated to combine these references even if they are in the same or similar fields. Prelim. Resp. 31. Petitioner fails to do so on this record. The absence of such reasoning is particularly noteworthy here in view of Ma’s numerous teachings which appear to discredit the “passive” method of pulling the composite strand from the extruder as recited in claim 4, which is challenged in each of Grounds 2 and 3. Patent Owner identifies no fewer than eight disclosures within Ma that seemingly disparage the passive “pulling” method and discuss benefits of the active “pushing” method. Prelim.

Prelim. Resp. 22–23. As Patent Owner correctly observes (id.), Petitioner’s general assertion that “Lipsker discloses that combinations of disclosed embodiments and features are possible and proper” (Pet. 20) does not constitute a reasoned explanation regarding why the skilled artisan would have combined Lipsker’s precoating and non-precoating actuator embodiments to arrive at the claimed subject matter. Moreover, Dr. Rosen’s declaration testimony on this point is entitled to little to no weight as it merely parrots the Petition.

    “Ma distinguishes between these two methods, noting that with the “active” method, “the forming quality of a previous layer does not influence the forming of the current layer,” while with the “passive” method, “the quality of a previous layer has a profound effect on the forming quality of the current layer.” Ex. 1007, 53. Ma sets forth other problems with using the “passive” method. See, e.g., id. at 95–96, 98–107, 143, 145–147, 149. For example, Ma teaches that during deposition using the “passive” method, “it is possible to make a big error, especially when the nozzle makes a big-angle turn” (id. at 98), and that “[a] toolpath error could be generated if an anchoring point is not formed properly” when using the “passive” method (id. at 143). Ma also discloses that forming speed is an issue with the “passive” method, (id. at 146), but discloses “[o]ne of the advantages [of the ‘active’ method] is that the forming speed is not limited by the solidification condition of the towpreg during the forming process” (id. at 168). 2. Analysis Claim 1 recites, inter alia, “moving the nozzle away from the anchor during discharging to pull the path of the composite material out of the nozzle.” Ex. 1001, 10:61–63. Petitioner contends that Ma teaches this limitation because “Ma discloses that ‘when the object moves relative to the nozzle during the forming process, the towpreg is pulled out by the object instead of being pushed out by nozzle pressure” and “the anchor points are used to pull the towpreg (‘the path of the composite material’) out of the nozzle during discharging.” Pet. 33 (citing Ex. 1007, 38, 72)(emphasis omitted). controlled layer manufacturing: an “active” method that pushes the composite material from an extruder’s orifice, and a self-anchoring or “passive” method, wherein the composite material is pulled out by the object. Ex. 1007, 7–8, 52–54. Here, Petitioner relies on Ma’s disclosures relating to the passive method. Petitioner, however, fails to provide a persuasive explanation as to why a POSITA would have selected Ma’s passive pulling method over Ma’s active pushing method for further development or improvement. Petitioner’s failure to do so is particularly noteworthy here, because Ma includes numerous teachings against the passive method of pulling the composite material through the nozzle. Indeed, Patent Owner identifies no fewer than eight disclosures within Ma that seemingly disparage the passive pulling method and discuss the benefits of the active pushing method. Prelim.

Id. at 11–14. In the absence of any explanation from Petitioner, we are not persuaded that a POSITA would have ignored Ma’s teachings against the passive pulling method and selected Ma’s pulling method over Ma’s active pushing method for further development and improvement.

    “Finally, the definition of output device in the priority ’765 Application (as in the Specification of the ’031 patent) is that an “[o]utput device [] is an electronic system capable of outputting digital content … Any device capable of playing or reading digital content in voice (e.g., music, speech) or data (e.g., text, document) is also a possible output device.” Prelim. Resp. 15 (alterations in original) (quoting Ex. 1011 (’765 application) ¶ 89, Ex. 1001, 16:29–41). An Internet appliance does fall within that definition. The ’765 Application also contemplates that an output device is a network device accessible through an IP address. See Ex. 1011, 14 (referring to “[i]dentification of an output device” by “IP address”).

    “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

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “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.

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededNot reached

    “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. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999).” slip op. at 10

    “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

  The Board denied institution for claims 1–27 because Petitioner did not show a reasonable likelihood that either asserted Jungck-based obviousness combination rendered the claims unpatentable.

    “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. Additionally, Petitioner’s references to collateral estoppel do not relieve Petitioner from the burden to describe its contentions regarding obviousness in the Petition.” slip op. at 15

    “Our reviewing court has held that “[c]ollateral estoppel protects a party from having to litigate issues that have been fully and fairly tried in a previous action and adversely resolved against a party-opponent.” Nestle USA, Inc. v. Steuben Foods, Inc., 884 F.3d 1350, 1351–1352 (Fed. Cir. 2018) (quoting Ohio Willow Wood Co. v. Alps S., LLC, 735 F.3d 1333, 1342 (Fed. Cir. 2013)). “It is well established that collateral estoppel, also known as issue preclusion, applies in the administrative context.” MaxLinear, Inc. v. CF CRESPE LLC, 880 F.3d 1373, 1376 (Fed. Cir. 2018) (citations omitted); Webpower, Inc. v. WAG ACQUISITION, LLC, Case IPR2016- 01239, Paper 21 at 26–28 (PTAB Dec. 26, 2017). “Issue preclusion [i.e., collateral estoppel] is appropriate only if: (1) the issue is identical to one decided in the first action; (2) the issue was actually litigated in the first action; (3) resolution of the issue was essential to a final judgment in the first action; and (4) plaintiff had a full and fair opportunity to litigate the issue in the first action.” In re Freeman, 30 F.3d 1459, 1465 (Fed. Cir. 1994); see also MaxLinear, Inc., 880 F.3d at 1377 (citing Blonder-Tongue Labs., Inc. v. Univ. of Illinois Found., 402 U.S. 313, 91 S. Ct. 1501, 28 L.Ed. 2d 788 (1971) (finding collateral estoppel applies to a patentee who had a full and fair opportunity to litigate the validity of a patent in a prior federal case.)). Patent Owner points out that the claims at issue in IPR2018-01443, 1444, 1513 (“prior IPRs”) did not include the “entire boundary” or “all traffic” limitations. Prelim. Resp. 26–27, 32, 44. We agree. Collateral estoppel does not apply because there are differences between the claim limitation at issue here and the adjudicated claim limitations at issue in the prior IPRs. See In re Freeman, 30 F.3d at 1465; accord MaxLinear, Inc., 880 F.3d at 1377–1378; cf. In re Arunachalam, 709 F. App’x 699, 702 (Fed.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

    “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. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng'g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’”).” slip op. at 7
