      “d. Multiplexing Being “Well-Known” Petitioner additionally argues that multiplexing techniques were well- known. See Pet. 34; Pet. Reply 18. Even if that is correct, however, it is insufficient because Petitioner must show that it would have been obvious to modify Yegoshin to add multiplexing, and merely establishing that multiplexing was known in other contexts is insufficient to show how or why Yegoshin should be modified.” slip op. at 22

PO Resp. 9. First, the parties in the ITC investigation agreed that “threat identifier” means “information that identifies one or more network threats.” Id. at 11 (citing Ex. 2004, 3). Second, the parties further agreed that “threat indicator” means “information that indicates a resource associated with a network threat,” “[f]or example, network addresses, ports, FQDNs, URLs, URIs, the type of threat, geographic information, anonymous proxies, actors, or the like.” Id. at 11–12 (citing Ex. 2004, 3).

    • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)InstitutedInstituted

      “7. CONCLUSION As discussed above, Petitioner presents substantively identical challenges to claims 1, 24, and 25 in the ’856 patent based on the same prior art and the same unpatentability theories as PAN presents in the PAN IPR. Compare Pet. 18–53, with PAN Pet. 18–50; see Prelim. Resp. 37, 41; supra § III.B.1; infra §§ III.C.6(c), III.D.3. Based on the current record, and for the reasons discussed above, Patent Owner’s arguments that the Petition fails to satisfy the “reasonable likelihood” standard for instituting trial lack merit. See supra §§ III.B.2–III.B.5. Hence, we determine that the Petition “warrants the institution of an inter partes review under section 314.” See 35 U.S.C. § 315(c).” slip op. at 35

      “determines that a newly received packet with encrypted data is correlated to the hostname corresponding to the whitelisted destination domain, the security device filters the packet by forwarding it to the remote server with the whitelisted destination domain. See Ex. 1004, 7:52–59, 16:36–42; Ex. 1003 ¶ 97; see also Ex. 1004, 6:1–11. Filtering the newly received packet with encrypted data by forwarding it to the remote server with the whitelisted destination domain occurs “without having to decrypt the encrypted secure tunnel session traffic.” Ex. 1004, 5:24–27, 5:35–42, 7:1–9, 11:7–19; see Ex. 1003 ¶¶ 101, 120. Hence, we disagree with Patent Owner that session traffic associated with a whitelisted destination domain is “simply forwarded to its destination without . . . filtering.” See Prelim. Resp. 20. Regarding the policy’s blacklist processing, if the security device determines that a newly received packet with encrypted data is correlated to the hostname corresponding to the blacklisted destination domain, the security device either blocks the packet (as Patent Owner contends) or filters the packet by forwarding it to a decryption engine. See Ex. 1004, 7:60–67, 9:61–67, 14:33–36, 16:43–48; Ex. 1003 ¶¶ 97–98, 101, 104, 115, 125, 134, 1144; Prelim. Resp. 19. Filtering the newly received packet with encrypted data by forwarding it to a decryption engine occurs “without having to decrypt the encrypted secure tunnel session traffic.” Ex. 1004, 5:24–27, 5:35–42, 7:1–9, 11:7–19; see Ex. 1003 ¶¶ 101, 120, 142. Further, filtering the newly received packet with encrypted data by forwarding it to a decryption engine results from applying a packet-filtering rule (a blacklisted destination domain) to the packet and corresponds to limitation [1.g] and the similar limitations in claims 24 and 25. See Ex. 1003 ¶¶ 116, 141–142. Buruganahalli identifies the following advantage due to filtering packets with encrypted data based on a hostname extracted from a hello message: “the rest of the stream” containing packets with encrypted data “can be forwarded without any decryption resulting in less state to track thereby enhancing performance.” Ex. 1004, 5:43–51; see Ex. 1003 ¶ 120.” slip op. at 20

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied

      “We disagree that factor (1) favors discretionary denial. When considering parallel litigation in light of Fintiv, the Board seeks to, among other things, minimize “inefficiency and duplication of efforts” when another tribunal may resolve “the same or substantially the same issues.” Fintiv, IPR2020-00019, Paper 11 at 5 n.7, 6, 14; see Intel Corp. v. VLSI Tech. LLC, IPR2019-01192, Paper 15 at 11 (PTAB Jan. 9, 2020). A stay of parallel litigation pending resolution of a Board proceeding “allays concerns about inefficiency and duplication of efforts.” Fintiv, IPR2020-00019, Paper 11 at 6. In the circumstances here, there are few, if any, “concerns about inefficiency and duplication of efforts.” In the 2017 Keysight case, neither the district court nor the jury determined the validity/invalidity of any claim in the ’856 patent over any prior art since the case settled before jury deliberations began. See Ex. 3004, 34; Prelim. Resp. 15; Opp. 3 n.1. Hence, factor (1) does not favor discretionary denial. (b)” slip op. at 44

    • PTAB / AIA Trials › Discretionary denial › General Plastic (serial petitions)Denied

      “Factor (1): Previous Petition For factor (1), Petitioner did not previously file a petition requesting an inter partes review of any claim in the ’856 patent. We recognize, however, that General Plastic has not been limited to proceedings where the same petitioner files multiple, staggered petitions and that “when different petitioners challenge the same patent,” we should consider “any relationship between those petitioners when weighing the General Plastic factors.” See, e.g., Valve, IPR2019-00062, Paper 11 at 9. In Valve, the Board noted that the petitioner Valve and a previous petitioner HTC “were co-defendants in the District Court litigation and were accused of infringing the [challenged] patent based on HTC’s VIVE devices that incorporate technology licensed from Valve.” Valve, IPR2019-00062, Paper 11 at 1, 10. Based on those particular facts, the Board determined that there was a “significant relationship” between Valve and HTC “with respect to Patent Owner’s assertion of the [challenged] patent.” Id. Here, in contrast to Valve, nothing in the current record indicates that there is a “significant relationship” between Petitioner and PAN “with respect to Patent Owner’s assertion of” the ’856 patent. That Petitioner copied PAN’s petition to present substantively identical challenges to claims 1, 24, and 25 in the ’856 patent does not create a “significant relationship” between Petitioner and PAN. Copying a previously instituted petition is “common in the joinder context” and “an accepted approach” because it is an efficient way to satisfy § 315(c)’s requirement to file a petition that “warrants the institution of an inter partes review.” Expedia, Inc. v. Express Mobile, Inc., IPR2022-00785, Paper 16 at 7–9 (PTAB Sept. 27, 2022). For these reasons, factor (1) does not favor discretionary denial.” slip op. at 50

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “patent. See Phillips, 415 F.3d at 1315–17. The term “extrusion lamination” does not appear anywhere in the ’482 patent outside of issued claim 1, but our understanding is supported by the prosecution history of the ’482 patent. Claim 1 as originally filed in the application that issued as the ’482 patent recited, in relevant part, “a reinforcing scrim of interwoven strands for supporting tensile forces in multiple directions; and at least one layer of thermoplastic material affixed to a side of the reinforcing scrim for providing a weather-resistant barrier.” Ex. 1002 (’482 patent prosecution history), 33. In response to a rejection of the claims as anticipated by U.S. Patent No. 5,523,357 to Peterson, describing a rubber mill calendering process, the applicant amended claim 1 to add the phrase “by extrusion lamination.” Id. at 71, 76. We find nothing to suggest that a person of ordinary skill in the art would have understood that amendment to add a requirement of an additional layer of thermoplastic material, separate and apart from the “at least one layer of thermoplastic material” already recited in the original claim, to serve as a binder between the scrim and the original layer of thermoplastic material. The applicant explained in remarks accompanying the amendment, “Peterson fails to disclose forming a thermoplastic layer over the reinforcing scrim by an extrusion lamination process.” Id. at 71 (italics, underlining, and capitalization omitted). We, thus, find that the added phrase specifies how the recited “thermoplastic material” must be “affixed” to “the side of the reinforcing scrim,” but does not alter the recited function of the thermoplastic material, namely, “for providing a weather-resistant barrier.” Although the applicant’s remarks further state that “[c]ontrarily [to the rubber mill calendering process of Peterson], the roofing underlayment of the present invention is formed by an extrusion lamination process which bonds the various layers together, including the pre-formed films, reinforcement scrim, and slip-resistant material” (id.), claim 1 does not recite “pre-formed films” or “slip-resistant material”; such additional layers are recited in dependent claims 5 (“metallized film”) and 2 (“layer of slip-resistant material”), respectively (Ex. 1001, 6:29, 6:37). Looking finally to the extrinsic evidence of record, including the testimony of the parties’ experts and other exhibits filed by the parties, we find no persuasive evidence to show that the recitation of extrusion lamination requires an additional layer in addition to the recited scrim and the at least one layer of thermoplastic material affixed to a side of the scrim. In that regard, notwithstanding Patent Owner’s contentions, we are not persuaded that “extrusion lamination” and “extrusion coating” are mutually exclusive. Rather, we credit Mr. Kaczkowski’s testimony that extrusion coating would also be considered “extrusion lamination” if, for example, it “results in the extrudate being permanently bonded to the substrate.” Ex. 2020, 28:17–20. While Patent Owner argues that Mr. Kaczkowski’s statement “is nothing more than restatement of the extrusion coating process,” and “[t]o think otherwise would require believing that ‘extrusion coating’ involves a thermoplastic layer that is extruded, and thus coated, onto a substrate with the result being that it is not permanently bonded, i.e., it will delaminate from the substrate” (PO Sur-reply 5), we disagree with Patent Owner’s further contentions that “[s]uch a product makes no sense” and “[u]nder Petitioner’s theories, the [prior art] would not work” (id.). Although there could indeed be extrusion coating processes that would result in coatings that are not permanently bonded, it does not follow that the cited prior art used such processes. Further, although a laminate may be affixed to substrate by an adhesive or other binder, we find no persuasive evidence in the record that the binder must be a separate layer from the laminate.” slip op. at 21

      “the “reinforcing scrim of interwoven strands” recited in claim 1 and Lou’s polypropylene polymer 2 to the recited “thermoplastic material.” Id. at 22– 23. Petitioner further contends that Lou discloses “affixing the thermoplastic material by extrusion lamination,” citing Lou’s disclosures that “[e]xtruder 20 supplies polypropylene polymer 2 through a slit orifice to deposit a thin continuous coating on the surface of sheet 1” and that coated sheet 3 is pressed by a calendaring nip formed by heated and unheated rolls. Id. at 23 (quoting Ex. 1005, 2:34–44) (citing Ex. 1003 ¶ 19; Ex. 1005, 2:45– 49).” slip op. at 34

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable

      “Having considered the parties’ respective arguments, we find that Petitioner’s contentions are supported by the evidence of record, and we find that Petitioner has articulated sufficient reasoning with rational underpinnings (including support both from the cited prior art and from Mr. Kaczkowski’s testimony) to combine the relevant teachings of Lou and Goodacre. We disagree with Patent Owner’s suggestion it is insufficient that Mr. Kaczkowski opined that a person of ordinary skill would have evaluated the proposed combination based on the combined teachings of the asserted references. As the Supreme Court has explained, When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under §103. KSR, 550 U.S. at 421. Patent Owner does not dispute Goodacre’s teachings or that combining those teachings with Lou would increase the tensile strength of Lou’s underlayment, but appears instead only to fault Mr. Kaczkowski for not determining whether those solutions would be less expensive than other alternatives. Such arguments are not persuasive. Although, as cited above, Petitioner alleges in the Petition that a skilled artisan would have recognized cross-lamination as “a simpler, less costly way to manufacture a nonwoven reinforcing scrim . . . consistent with Lou” (Pet. 37), we find that is only one among several reasons identified by Petitioner and Mr. Kaczkowski for the combination (see, e.g., id. at 34–35 (additionally identifying increased tensile strength as a well-known benefit of orienting polyolefin fabric)), each of which is independently persuasive.” slip op. at 53

      “Motion to Exclude.

As Petitioner points out, Dr. Reitman’s testimony is presented in the Patent Owner Response in alleged support of Patent Owner’s argument. See Reply Mot. Excl. 1 (citing PO Resp. 22 (“Maureen Reitman recognized that ‘extrusion coating’ and ‘extrusion lamination’ were two different processes”; “[A]s Ds.
