“Owner’s interpretation of “carrier” as meaning “one or more components for supporting ROSA components such as an AWG.” Dec. 9 (quoting Pet. 11). For our analysis of Petitioner’s challenges, we referred to this interpretation of “carrier” as Petitioner’s second alternative construction. Id. We also noted that Petitioner appeared to dispute Patent Owner’s interpretation when it argued that “carrier” should mean “a ceramic or silicon substrate.” Id. (quoting Pet. 10). We referred to this interpretation of “carrier” as the first alternative construction. Id. Rather than resolve this apparent dispute about the meaning of “carrier,” we found that both of Petitioner’s anticipation challenges failed under both interpretations of “carrier.” Id. at 10–26. Because we found that Petitioner had failed to carry its burden regardless of which interpretation of “carrier” applied, we found it unnecessary to resolve the dispute over that interpretation. Id. at 9–10. For the reasons expressed in Parts II.B–C below, we maintain our conclusion that Petitioner has failed to demonstrate a reasonable likelihood of proving that either Shen or Soldano anticipates any claim under either interpretation of “carrier.” Accordingly, Petitioner fails to demonstrate an abuse of discretion in our alleged “refusal” to interpret “carrier.”” slip op. at 3

Nevertheless, we infer that Petitioner intends its statements of “caselaw” to refer to the requirements to make out a case for anticipation. If so, Petitioner demonstrably miscasts what appear to be the legal principles for proving anticipation.

Id. at 14–15. In particular, we were not persuaded that “Seo creates a large lateral electric field like the one described in Choi,” and, in any case, we disagreed that “Choi teaches that a large lateral electric field removes fast charges.” Id. at 15. Accordingly, regardless of the duration of the voltage application described in Seo, Petitioner failed to show that the combination of Seo and Choi would result in removal of fast charges. We further determined that Petitioner’s combination of Nam with Choi was problematic for similar reasons, given Petitioner’s reliance on similar arguments. See id. at 20.” slip op. at 10

“the knowledge of one of ordinary skill in the art relating to charge-trap memory devices demonstrates fast charge removal. See Pet. 36, 81–82. And although Petitioner cites its declarant, Dr. Liu, for the proposition that “Seo discloses, and would have been understood to disclose, performing its read operation on charge-trap memories, which removes fast charges,” Dr. Liu does not cite objective evidence to support this assertion, aside from the ’342 patent itself. Id. at 36 (citing Ex. 1003 ¶ 136). Moreover, Dr. Liu’s testimony simply circles back to logic similar to that relied on with respect to the inherency theory, namely that, given certain similarities between Seo and the ’342 patent, Seo removes fast charges because the ’342 patent teaches removing fast charges, even though Seo does not explicitly teach doing so. See Ex. 1003 ¶ 136 (“[A] POSITA would have immediately understood from reading Seo that Seo is disclosing its read operation as applicable to Flash memories, including Flash charge-trap memories. And as the ’342 states, Seo’s operation would remove fast charges in a charge-trap memory.” (citing Ex. 1001, Abstract)). As already discussed, we disagree with this logic based on the lack of sufficient evidence to support its conclusion. See Dec. 13 (“Petitioner and Dr. Liu do not provide any objective evidence or explanation as to how or why a POSITA would have understood that Seo’s voltage amounts applied during Seo’s time periods operate the same way [as in the ’342 patent] on Seo’s memory device to generate fields with sufficient magnitude and duration to remove fast charges.”). Petitioner’s assertions regarding Nam suffer from the same shortcomings.

“or overlooked any matter. As we explained in the Institution Decision, the ’255 patent discloses that the recited characterization profile allows the system to convert the intensity values measured by the intensity sensor into luminance values based on the sensor’s ability to sense the particular color of the measured light. Inst. Dec. 21; Ex. 1001, 11:41–48. The ’255 patent states that “the light intensity sensor’s 280 ability to sense . . . a particular color” is the “the light intensity sensor’s 280 profile for [that] particular color.” Ex. 1001, 11:45–47. The ’255 patent further states that this “[l]ight intensity sensor 280 characterization is essential for high precision computations.” Id. at 11:48–49. Thus, as we stated in the Institution Decision, the recited “characterization profile” refers to a conversion factor used to convert the measured light intensity into luminance. As this conversion factor is based on the light intensity sensor’s ability to sense the particular color of light reflected by the road sign, we agree that it is empirical information. Patent Owner fails to explain adequately how the fact that the ’255 patent discloses storing multiple conversion factors for multiple colors of measured light in a digital look-up-table (see id. at 11:56–59 (“The light intensity sensor characterization 275 is empirical information about the light intensity sensor 280 that is used to create the [look-up table] 475.”)) has any bearing on our interpretation.” slip op. at 4

Neither Guinn nor Vectra Fitness involved a situation in which a determination about the patent, once made, was required to be unwound in light of a subsequent statutory disclaimer. Instead, Vectra Fitness related to a question of how to resolve post-disclaimer proceedings, and Guinn dealt with whether to apply a rule treating the disclaimer of all claims involved in an interference proceeding as a request for adverse judgment against the disclaiming party.

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

The Board denied Petitioner’s rehearing request and maintained that claims 41–43 were not shown unpatentable because the evidence did not establish network-interface reassembly.

“II. STANDARD OF REVIEW A party requesting rehearing bears the burden of showing that the decision should be modified. 37 C.F.R. § 42.71(d). The party must identify specifically all matters we misapprehended or overlooked, and the place where each matter was previously addressed in its petition. Id.” slip op. at 4

“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
