      “decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may be determined if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors. See Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004). The party challenging the decision has the burden of showing a decision should be modified, and the request for rehearing must specifically identify all matters the party believes the Board misapprehended or overlooked and the place where each matter was previously addressed in its papers. 37 C.F.R. § 42.71(d).” slip op. at 2

      “articulated why it would have been obvious to modify the recovery tank of Xia’s non-wet-filter vacuum to include a strainer basket like that shown in Park’s wet-filter water vacuum. Dec. 13.2 Based on review of the disclosure of Park, the Decision found that the strainer was used to help the wet-filter mechanism work. Id. at 8–10. The Decision noted that the strainer served its purpose at two times—during recirculation of the filtering water when in use and during draining of the filtering water when finished. Id. Thus, the Decision found that the strainer’s purpose was to solve problems unique to wet-filter vacuums. Id. at 11. The Decision found insufficient evidentiary support for Petitioner’s assertion that Park suggested its strainer would be useful in devices like Xia that did not have wet filters. Id. The Decision also found insufficient evidentiary support for Petitioner’s assertion that a person of ordinary skill in the art would nevertheless recognize that Park’s strainer could be useful in devices that did not have wet filters. Id. at 12–13. Accordingly, the Decision determined that the Petition did not meet the burden for institution. Id. at 13.” slip op. at 3

      “one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill”). However, we disagree that Petitioner has established the factual underpinnings required to support such a theory. Petitioner’s Request directs us to no evidence the Decision missed on this topic. As noted in the Decision, the expert testimony relies on Park or on other devices in which the strainer is used to prevent clogging of recirculation devices. Dec. 13, n.3. These devices teach no more than Park—strainers used to permit recirculation systems to operate without clogging. See id. The Petition did not identify sufficient evidence that would support a finding that a person of ordinary skill in the art would have recognized, before the date of invention, the obviousness of using Park’s strainer in Xia, a device that operates in a different way than Park. See KSR, 550 U.S. at 417 (noting a precondition of the application-of-a-known-technique rationale is that the technique used to improve a device improves the device “in the same way.”) (emphasis added).” slip op. at 6

      “sense” reason to combine the references, premised on testimony alleging that debris dumped from a wet vacuum tank could clog the drain. Req. Reh’g. 11–12. Petitioner does not direct our attention to where this theory of unpatentability was raised; arguments not raised cannot have been overlooked. In any event, the expert testimony cited is not entitled to persuasive weight because it is not supported by sufficient evidence or technical reasoning. Xerox Corp. et al v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (Decision Denying Institution) (precedential). As explained in the Decision, Petitioner points to no evidence that there was a known problem of drain clogs when disposing of waste water from devices like Xia, nor does Petitioner’s expert explain the reasons why a person of ordinary skill in the art would have nevertheless recognized the problem and its solution. Dec. 12 (“Petitioner has not explained why it would have been obvious to modify Xia by borrowing features that are meant to solve problems unique to water-filter vacuum cleaners”), 13 n.3 (finding that Petitioner’s expert “does not provide an explanation of why a person of ordinary skill in the art would look to add a recirculation filter to devices that do not use recirculation”). Unless there is credible evidence showing otherwise, any perceived obviousness today is only apparent in hindsight. See, e.g., Cardiac Pacemakers, Inc. v. St. Jude Medical, Inc., 381 F.3d 1371, 1376 (Fed. Cir. 2004) (“Prior knowledge in the field of the invention must be supported by tangible teachings of reference materials, and the suggestion to combine references must not be derived by hindsight from knowledge of the invention itself.”); see also Leo Pharmaceutical Products, Ltd. v. Rea, 726 F.3d 1346, 1353 (Fed. Cir. 2013) (“an invention can often be the recognition of a problem itself”); Stratoflex, Inc. v. Aeroquip Corp., 713 F.2d 1530, 1538 (Fed.

Brugh does not “instruct” a POSA to perform either of these actions. Rather, Brugh provides a method comprising, in relevant part, “a) determining the species of flying vertebrate inside the building; b) selecting bird netting; . . . [and] d) positioning the netting for capture based on the species of flying vertebrate and their flight characteristics utilizing the height adjustable poles to raise the netting.” Ex. 1004 ¶¶ 8–10, 15 (emphasis added). There is no “instruction” that the location of the netting is adjusted based on the flight pattern; rather, the height is adjusted. Brugh further provides for “determin[ing] how [the flying vertebrate] flies, e.g., a bat flies in a different pattern than a sparrow” and using the flight pattern “to place the netting in relationship to the position of the flying vertebrate.” Id. ¶ 45. There is no “instruction” that the determining of the flight pattern must be by observing the flying vertebrate (as opposed to researching the flight pattern of the species of the flying vertebrate) or that the netting is placed in relationship to and observed or expected position. b) “The Board’s analysis ignores common sense.” Reh’g Req. 4. Petitioner contends that the Board ignored common sense, as “at some point a POSA necessarily would have observed some species of bird flying near some perimeter walls within some building.” Reh’g Req. 4; see also id. at 6 (“It was common sense that a POSA would eventually observe a bird near a perimeter wall and place Brugh’s capture device accordingly.”), 7 (“[T]he Board . . . substitutes a rigid review of the prior art’s disclosure for common sense. . . .”)). This argument is unavailing. “[W]hile ‘common sense’ can be invoked, even potentially to supply a limitation missing from the prior art, it must still be supported by evidence and a reasoned explanation.” Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355, 1363 (Fed. Cir. 2016). As explained above, Petitioner’s argument discounts the inventor’s discovery, in which he spent “countless hours” before discovering that birds fly along the perimeter wall of a building’s interior. Ex. 2001 ¶ 16. Further, as discussed above, Brugh does not instruct nor teach a POSA to observe flight patterns and determine or adjust the locations of the nets accordingly. We are not persuaded that the inventor’s discovery was merely “common sense,” and if it was, Petitioner should have submitted sufficient evidence to support such a finding. See Arendi, 832 F.3d at 1363. As explained in our Decision, Petitioner did not. See, e.g., Dec. 32 (“Petitioner provides insufficient evidence that bats or other flying animals are likely to fly ‘at or proximate to a perimeter wall and at or near the ceiling’ such that a POSA would find it obvious to place a net at or proximate to the perimeter of a wall within a building”). A request for rehearing under 37 C.F.R. § 42.71(d) is not an opportunity for Petitioner to simply reargue issues we previously addressed.” slip op. at 6

      “Petitioner’s argument does not give enough credit to the inventor’s discovery.

We do not find Petitioner’s citation to the inventor’s testimony, in which the inventor testifies to having “spent countless hours” working on his discovery, to support Petitioner’s argument that the inventor’s discovery would have been obvious based on Brugh’s “instruct[ions to] a POSA to observe the ‘flight patterns’ of these birds” and to “place nets where the birds are observed flying in the building.” Reh’g Req. 4 (citing Ex. 1008 ¶¶ 15, 45; Ex. 1004 ¶¶ 32, 72, 75).

      “We do not agree with Patent Owner’s arguments. As stated in our Decision, Agin discloses that parameters may be determined based on statistics on power control results for a transmission period before said transmission interruption, including “the largest [of] the variations of a received signal power before the interruption. See Dec. 24; Ex. 1004, 6:9– 13. Thus, Agin acknowledges that variations are possible, and can be taken into account, even with a single base station. Chen discusses that a power control processor determines the correct power control command by use of averaging or weighted averaging from “each transmitter’s signal at the receiver.” Ex. 1005, 10:45–56. Thus, although Patent Owner is correct that those signals are received from multiple transmitters, in Chen, Agin demonstrates that variations can occur and can be compensated for with even a single transmitter, countering Patent Owner’s argument that there would be nothing to average over. Taking Agin and Chen together, as Petitioner has asserted, we remain persuaded that ordinarily skilled artisans would have applied the weighted average, disclosed in Chen, in Agin, even if a single transmitter/ base station is utilized.

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)). Under at least some circumstances, a reference may be a printed publication under § 102(b) if it was “displayed to the public,” even if it “was not later indexed in any database, catalog, or library.” In re Klopfenstein, 380 F.3d 1345, 1350 (Fed.

There are several factors relating to whether such a display is sufficient to constitute a printed publication, including “the length of time the display was exhibited, the expertise of the target audience, the existence (or lack thereof) of reasonable expectations that the material displayed would not be copied, and the simplicity or ease with which the material displayed could have been copied.” Id. In addition, distribution of a reference at a professional conference may, under at least some circumstances, constitute sufficient dissemination to show public accessibility.

By virtue of this public accessibility, both Voswinckel JESC and Voswinckel JAHA were printed publications early enough to qualify as prior art under 35 U.S.C. § 102(b). G. Asserted Obviousness over ’212 Patent, Voswinckel JESC, and Voswinckel JAHA Petitioner argues that claims 1–8 would have been obvious over the combination of the ’212 patent, Voswinckel JESC, and Voswinckel JAHA. Pet. 30–46. As discussed above, Petitioner has shown by a preponderance of the evidence that both Voswinckel JESC or Voswinckel JAHA qualify as prior art. Accordingly, we do not disturb the obviousness analysis in the Final Written Decision, which relies on the prior-art status of Voswinckel JESC and Voswinckel JAHA. Final Dec. 12–35. slip op. at 12

      “II. STANDARD OF REVIEW “The burden of showing a decision should be modified lies with the party challenging the decision.” 37 C.F.R. § 42.71(d) (2022). In a rehearing request, the party challenging the decision “must specifically identify” (1) “all matters the party believes the Board misapprehended or overlooked” and (2) “the place where each matter was previously addressed” in an earlier submission. Id.; see Consolidated Trial Practice Guide at 90.3 “A rehearing request is not an opportunity for the requesting party to reargue its case or merely to express disagreement with the underlying decision.” MicroSurgical Tech., Inc. v. Regents of Univ. of Colo., PGR2021-00026, Paper 14 at 2 (PTAB Aug. 12, 2021). “Nor is it an opportunity for the moving party to present new arguments that were not in its original submissions.” Id.” slip op. at 3

      “Patent Owner does not explain why issue preclusion permits the Board to hold the district court’s finding that Cisco “copied software functionality from the [infringed] patents” against Petitioner. See Prelim. Resp. 16, 54–56; Req. Reh’g 3, 14–15. Issue preclusion “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) the party defending against preclusion “had a full and fair opportunity to litigate the issue in the first action.” SynQor, Inc. v. Vicor Corp., 988 F.3d 1341, 1353 (Fed. Cir. 2021). Patent Owner does not address any of these requirements for issue preclusion. See Prelim. Resp. 16, 54–56; Req. Reh’g 3, 14–15.” slip op. at 13

      “Regarding the policy’s whitelist processing, if the security device 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 ¶ 90; 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 ¶¶ 94, 113. Further, filtering the newly received packet with encrypted data by forwarding it to the remote server with the whitelisted destination domain results from applying a packet-filtering rule (a whitelisted destination domain) to the packet. Hence, we disagree with Patent Owner that Buruganahalli’s security devices process whitelisted packets by “forward[ing] the entire encrypted stream without . . . filtering encrypted packets.” See Req. Reh’g 10. We also disagree with Patent Owner that “encrypted packets in whitelisted sessions” are (1) “forwarded without applying any packet-filtering rules” and (2) “allowed uninspected.” See id. at 11 n.1, 13. 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 ¶¶ 90–91, 94, 97, 108, 118, 127, 137; Req. Reh’g 10–11, 13. 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 ¶¶ 94, 113, 135. 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 ¶¶ 109, 134–135. The Institution Decision explained how Buruganahalli’s security devices may filter packets comprising unencrypted data and packets comprising encrypted data according to claims 1, 24, and 25 by applying a whitelist/blacklist policy to the packets. See, e.g., Inst. Dec. 57–60, 66–67, 69–71. As the Institution Decision explained and as discussed above, “for each session packets comprising unencrypted data and packets comprising encrypted data are correlated and filtered based on the hostname (destination domain) extracted from the handshake traffic, and then the correlated and filtered packets are processed separately from packets destined for other domains.” See Inst. Dec. 69–70; Ex. 1003 ¶¶ 109, 120–121, 133–135; Ex. 1004, 7:39–67, 8:55–60, 11:47–51, 14:21–33, 14:50–55, 16:32–48. Buruganahalli discloses additional filtering after forwarding a newly received packet with encrypted data to a decryption engine, e.g., as occurs in Buruganahalli’s Figure 3B embodiment. See, e.g., Ex. 1004, 6:17–22, 9:67–10:4, 12:4–64, Fig. 3B. But claims 1, 24, and 25 use the transitional term “comprising.” Ex. 1001, 25:14, 28:59, 29:29–30. Hence, the claims do not “exclude unrecited elements,” such as additional filtering after forwarding a newly received packet with encrypted data to a decryption engine. See Regeneron Pharm., Inc. v. Merus N.V., 864 F.3d 1343, 1352 (Fed. Cir. 2017) (citing Manual of Patent Examining Procedure § 2111.03).” slip op. at 8

In the Decision Denying Institution, we explained that Petitioner’s reasons to combine are insufficient because “Petitioner does not address the full teachings of Gullman.” Dec. 22, 25. We stated “[c]ontrary to Petitioner’s assertion (Pet. 33; Ex. 1003 ¶ 81) and consistent with Patent Owner’s position and Dr. Russ’s testimony that Gullman’s system eliminates the risk of the biometric template and input from being stolen during transmission (Ex. 2001 ¶ 119), Gullman describes its system as ‘secure,’ providing ‘secure identification,’ and, importantly, as providing ‘[t]ransmission security.’” Dec. 22–23 (citing Ex. 1004, 6:46–56). We particularly noted (id. at 23) Gullman’s teachings as follows: The method and apparatus of the present invention have significant advantages over known security systems. Reliable and secure identification is provided which eliminates the need for the user to memorize a code or carry a printed memorandum of the code. Transmission security is provided which is convenient, secure and useful on existing access devices of host systems in current use. In particular, the method and apparatus obviate the need for specially-designed hardware additions or modifications to existing access devices. Ex. 1004, 6:46–56. As we noted in the Decision to Institute, the Petition did not address Gullman’s teaching that its system provides “significant advantages” over known, more complex systems, which might have led an ordinarily skilled artisan away from using Padgett’s more complicated hashing process.

      “Put another way, the finding that Petitioner did not admit that the disputed limitation is not taught by Tanenbaum was not a finding that Petitioner proved that that limitation is taught or suggested by the asserted prior art. As the Federal Circuit explained, “the Board’s rejection of certain arguments made by [Patent Owner] does not necessarily support the Board’s finding that the asserted prior art teaches or suggests reassembly in the network interface,” and “[t]hat is especially the case here, where the parties’ briefing focuses on the disclosure of the reassembly limitations by one reference (Thia), but the Board appears to have relied on a different reference (Tanenbaum) to support its finding.” Id. at 1371–72 (emphasis added). The Court, accordingly, vacated the Board’s obviousness determination as to claims 41–43 and remanded “for the Board to reconsider whether the asserted prior art teaches or suggests the entirety of the reassembly limitations, including the requirement that reassembly takes place in the network interface.” Id. at 1373 (emphasis added). And as we explained in the Decision on Remand, after such reconsideration, we were not persuaded that the combination of Thia and Tanenbaum teaches or suggests “a flow re-assembler, disposed in the network interface,” as recited in claim 41, or a “network interface comprising . . . a re-assembler,” as recited in claim 43. RFWD 22–25. While Petitioner argues that “the RFWD tacitly acknowledges that the Petition’s discussion of Tanenbaum is much more extensive than the discussion on p. 77 that the Federal Circuit described as ‘conclusory’” (Req. Reh’g 3 n.4 (citing RFWD 23–24)), we find nothing in that “more extensive” discussion that establishes by a preponderance of the evidence that the asserted combination teaches or suggests reassembly in the network interface.” slip op. at 6
