    “8–11, 13, 15, 17, and 19, and remanded “for consideration of the patentability of those claims.” Id. at 14. We understand both the reversal and vacature are with respect to Ground 1 of alleged unpatentability, not Ground 2, because the Federal Circuit’s decision did not discuss anything relating to Ground 2. Paper 43. The parties agreed. Paper 44. In this remand proceeding, neither party requested the filing of additional briefing or evidence. In a telephone conference call, both parties expressed agreement with the Board (1) that “there is no issue regarding collateral estoppel or issue preclusion with respect to dependent claims 8– 11, 13, 15, 17, and 19, and (2) that the remand proceeding would not involve the Board revisiting any matter or issue concerning alleged obviousness of claims 1, 8, 9, 11, 13, 17, and 19 over Ground 2.4 Papers 43, 44. The parties also agreed that the remand proceeding would only involve the Board reviewing the alleged obviousness of dependent claims 8–11, 13, 15, 17, and 19 as obvious over Rautiola, Regnier, and Sainton. Id. We have authority to conduct this inter partes review under 35 U.S.C. § 6. This Final Written Decision on Remand is issued pursuant to 35 U.S.C. § 318(a) and 37 C.F.R. § 42.73. On the record before us, which is the same as the record before us at the time we issued the first final written decision (Paper 34), we determine that Petitioner has proved by a preponderance of the evidence that claims 8– 11, 13, 17, and 19, but not claim 15, of the ’936 patent are unpatentable over Rautiola, Regnier, and Sainton.” slip op. at 3

The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date.

When I weigh the evidence, I find it to be one-sided, with all of the expert testimony weighing against Petitioner or avoiding the issue altogether. Thus, I would not find that Petitioner has met its burden to prove, by a preponderance of the evidence, that Zhao teaches claim limitation 1e. Moreover, even if the Majority is correct about how Zhao’s RCR algorithm works, all that shows is that the detection of object presence in a previous image can be used to disambiguate segments (e.g., limbs) of an already detected object (e.g., a person), not that it can be used to detect the object in the image in the first place, as required by the claim language.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Petitioner, supported by Dr. Schmidt’s testimony, has proposed that a person of ordinary skill in the art at the time of the invention “would have had a degree in computer engineering, computer science, or a similar discipline, along with 2 years of professional experience in the fields of networking and network-based systems or applications, or an equivalent level of skill, knowledge, and experience,” and would have been “aware of and generally knowledgeable about how devices were provisioned onto wireless networks, along with standards applicable to well-known methods for communication such as Wi-Fi, Bluetooth, and NFC available at the time the ’615 patent was filed.” Pet. 18 (citing Ex. 1003 ¶¶ 37–39). Patent Owner does not challenge the qualifications proposed by Petitioner for a person of ordinary skill in the art. See generally PO Resp.; PO Sur-reply. We find Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the prior art of record, see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction neededOther

    “We largely agree with Patent Owner that there is no explicit claim- construction dispute. We address Patent Owner’s issues of what ordinarily skilled artisans would have considered in creating and implementing packetfiltering rules in the discussion below. The preservation of the flow of normal legitimate network traffic without disruption is one aspect that those with a working knowledge of packet-switched networking, firewalls, security policies, communication protocols and layers, and the use of customized rules to address cyber-attacks would have considered. Nonetheless, overall, we determine that the plain and ordinary meaning of “configured to prevent an exfiltration operation,” does not require preventing all exfiltrations from occurring, nor allowing all non-exfiltration traffic, and that we need not consider the preservation of the flow of normal legitimate network traffic without disruption in the context of that claim construction. We determine that no claim terms need to be construed expressly for purposes of this Decision.” slip op. at 10

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “how and why persons of ordinary skill in the art would have modified the existing rules to prevent exfiltrations. PO Sur-reply 3. Patent Owner also argues that Petitioner’s assertions to make them “drop” rules, per Sourcefire, relies on what an administrator could have done, not what they would have been motivated to do. Id. at 4–5 (citing Pet. 57–58). We disagree with Patent Owner’s arguments. We continue to be persuaded that one of ordinary skill in the art, combining Sourcefire and Emerging Threats, would have understood that downloaded rules should be reviewed, and it would have been obvious to enable rules that such persons deemed appropriate. We find Dr. Staniford’s testimony to be persuasive on this point. See Ex. 2011, 67:10–68:24, 69:8–72; Ex. 1020, 109. We acknowledge that downloading all of a particualr ruleset from Emerging Threats and enabling all the rules, might have resulted in a drop in performance of the network appliance, but, at the same time, we are significant drop in performance, especially if a potential threat might be sufficient to warrant a minor performance hit. Patent Owner’s counsel acknowledged at oral hearing that instituting all rules of a set in “alert” mode would not result in a decrease in performance, even though some computational outlay must be engaged to engage those alert rules. See Hr’g Tr. 24:24–25:4. We are persuaded that judiciously implementing certain rules would not necessary result in a network device that is unusable. Additionally, there is testimony from Dr. Staniford that “you start out with your rules in alert because there might be false positives. I mean, for the best rule in the world, Snort wasn’t known for false positives in the rules, when you apply them to a large network.” Ex. 2011, 68:2–7. As such, we continue to determine that it would have been obvious, in combining Sourcefire with Emerging Threats, for one of ordinary skill in the art to have downloaded rules and implemented specific rules.” slip op. at 24

  • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightDecided for petitioner

    “Reviewing all of the evidence of record, we are persuaded that the Petition’s obviousness rationale based on Sourcefire and Emerging Threats is not guided by impermissible hindsight bias. We find persuasive Dr. Staniford’s testimony that one of ordinary skill in the art would have understood that “this rule [SID:2003021] was not directed to looking for instances of exploits or attacks (which would be invisible within the encryption) but rather was looking for exfiltration of some kind of encrypted data.” Ex. 1003 ¶ 228. As discussed by Petitioner, such recognition was also made by Mr. Marinho and Dr. Goodrich, such that the rule would have been understood to possibly prevent exfiltrations. We continue to be persuaded that Petitioner provides that a correspondence exists between the REQUIRE-TLS-1.1-1.2 operator in the ’343 Patent and SID:2003021 in Emerging Threats, in that both detect an SSL/TLS version in application packet header field values to detect exfiltration attempts using out-of-date encryption protocols. Pet. 43 (citing Ex. 1003 ¶¶ 229–230). We are ’343 Patent discloses the interruption of a similar type of exfiltration, without resorting to impermissible hindsight bias, that Patent Owner asserts. Patent Owner has provided no evidence that Petitioner used the specification of the ’343 Patent to find an applicable rule in Emerging Threats, as opposed to the testified-version provided by Dr. Staniford that he recalls “working on a similar feature where we looked for large encrypted transmissions outbound from the network on non-HTTP ports as a possible symptom of exfiltration of large amounts of data.” Ex. 1003 ¶ 228. Thus, we are not persuaded by Patent Owner’s arguments.” slip op. at 30

  • Obviousness (§103) › Motivation to combine / reasonable expectation of success › Teaching awayMotivation foundTeaching away not foundDecided for petitioner

    “Applicant’s foregoing computer security embodiment, utilizes two distinct communications channels and a random number generator in order to ensure that an authorized user of a computer system is notified that someone or something is seeking access to the computer system with his or her password. Moreover, Applicant’s foregoing invention is very cost effective as it employs substantially “off the shelf” and readily available components. Further, the use of a “secret” password, a “secret” substantially random number, and a “secret” second channel allows for multiple levels of security before access to the computer system is achieved and provides enhanced security over the prior art. Ex. 1005, 7:16–28. We do not agree with Patent Owner that these statements unequivocally support its position that Veneklase’s two-step authentication process is a principle of operation of its system. Rather, the quoted statements indicate that Veneklase’s use of two distinct communication channels and a random number generator are key features of Veneklase’s system that provide multiple levels of security and enhance security of that system. As modified Veneklase’s system still uses two distinct communication channels and a random number generator. Thus, to the extent that Veneklase’s enhanced security measures (i.e. two distinct communication channels and a random number generator) are a principle of operation of Veneklase’s system, the proposed modification does not destroy this principle of operation or render Veneklase’s system inoperable. Moreover, incorporating Jonsson’s teachings related to using an algorithm to create a new password would not destroy the principle of operation of Veneklase’s security system because it only changes how Veneklase accomplishes its goal of preventing unauthorized access to a computer system, rather than defeating its goal of preventing such access. See In re Mouttet, 686 F. 3d 1322, 1332 (Fed. Cir. 2012). Further, we do not agree that Plas-Pak (a routine decision11) supports Patent Owner’s contention that the proposed combination impermissibly changes Veneklase’s principle of operation as Patent Owner has not identified differences between the two authentication processes that would be “unlikely to motivate a person of ordinary skill to pursue” the proposed combination.

    “motivation to combine Veneklase and Johnson. PO Resp. 20–21. Petitioner does not propose modifying Veneklase to include Jonsson’s teachings solely because the security of the proposed combination is superior to the security in Veneklase. Rather, Petitioner asserts that “[a] POSITA would have been motivated to make such a combination because having only the one password transmitted via the computer system is more efficient and secure.” Pet. 31 (citing Ex. 1003 ¶ 91). The Petition explains how the combination is more efficient in that it requires only a single step which reduces the amount of time required for the authentication process. Id. We also agree with Petitioner’s reasoning that a person of ordinary skill in the art would have been “motivated to combine Veneklase and 11 “A routine decision is binding in the case in which it is made, even if it is not designated as precedential or informative, but it is not otherwise binding authority.” Patent Trial and Appeal Board, Standard Operating Procedure 2 (Rev. 11) 2 (July 24, 2023), available at https://www.uspto.gov/sites/default/files/documents/20230724_ptab_sop2_r ev11_.pdf. Jonsson because the combination merely uses a known technique to improve similar devices in the same way.” Pet. 33 (citing KSR, 550 U.S. at 401). Jonsson discloses a known algorithm and Veneklase discloses a system that is similar to Jonsson’s. In the absence of any evidence that applying Jonsson’s algorithm to Veneklase’s system is beyond the skill of a person of ordinary skill in the art, we agree that “the improvement is [no] more than the predictable use of prior art elements according to their established functions.” KSR, 550 U.S. at 401.” slip op. at 26
