“We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed. Cir. 2022) (construction of term in independent claims should not render dependent claims superfluous or lacking scope).” slip op. at 20

“We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra. Having decided proper constructions for the disputed terms, we proceed in our analysis to consider the parties’ arguments concerning the challenge grounds. In the following sections, we apply the plain meaning of the claim terms, and as necessary, specify what the plain meanings are.” slip op. at 23

“C. Level of Ordinary Skill in the Art Petitioner contends as follows: A POSITA8 would have had a bachelor’s degree in electrical engineering, computer engineering, or a similar discipline, and three to four years of experience working in signal processing and/or communication systems/networks. Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art. We adopt and apply Petitioner’s proposed skill level because it is consistent with the problems and solutions identified in the ’690 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Resp. 33–45. Petitioner disagrees that the present record sufficiently shows that the inventors of the ’450 patent conceived of the invention before the effective date of Krantz or Herrmann and that the inventors exercised reasonably continuous diligence in reducing that invention to practice. See Prelim. Reply 1–7. In particular, Petitioner raises questions with respect to the independence of Patent Owner’s evidence from the inventor testimony that evidence is intended to corroborate, as well as with respect to whether the evidence offered by Patent Owner sufficiently shows conception, reduction to practice, and reasonably continuous diligence. Id. We do not think the information of record is sufficient to antedate Krantz and Herrmann such that we should deny institution of inter partes review on that basis. First, Patent Owner’s arguments rely on the testimony of inventor Stacey C. Lum, who has not yet been subject to cross-examination. See Prelim. Resp. 35–45 (citing Ex. 2003). Second, Petitioner identifies several issues where further development of the record may be helpful. For example, Patent Owner’s asserted date of conception is associated with the date of an engineering specification included in the record as Exhibit 2011. See Prelim. Resp. 35–36 (citing Ex. 2003 ¶ 12; Ex. 2011; Ex. 2012). We agree with Petitioner (see Prelim. Reply 4–5) that it is unclear, based on the present record, whether Exhibit 2011 corroborates the testimony supporting Patent Owner’s conception date given that the present record does not establish the author of Exhibit 2011. See Ex. 2003 ¶ 22 (inventor Stacey C. Lum testifying only that “InfoExpress personnel drafted EX2011”). These and other issues relating to the prior-art status of Krantz and Herrmann are, in our view, best left for trial after full development of the record.3” slip op. at 15

“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.

“Regarding the claimed “predefined threshold value” or “predefined illuminance,” Petitioner asserts that “Alden’s system can ‘provide illumination to independently controlled segments [e.g., ‘subsections’] each operable within a range of intensities between the high and the low beam state” and that Alden’s “intensities in between high beam and low beam (e.g., medium) are the claimed ‘predefined threshold value’ which the low beam would be below and the high beam would be above.” Pet. 25. We tend to disagree with this analysis, as it does not appear that a “range of intensities” is a “predefined threshold value” or “predefined illuminance,” if those terms are given their ordinary meaning. We thus conclude that, on this record at least, Petitioner has not shown a reasonable likelihood that Alden anticipates these claims. Regarding obviousness in view of Alden alone, Patent Owner argues that Petitioner has “failed to establish or demonstrate multiple elements that are required to support an obviousness conclusion, including explaining how Alden must be modified (i.e., identifying the differences between the claimed invention and Alden) and explaining why a POSA would be motivated to so modify Alden (i.e., providing some articulated reasoning with some rational underpinning to support an obviousness conclusion).” Prelim.

“First, Patent Owner asserts that Alden is “fatally ambiguous” and “fails to provide an enabling disclosure” because it describes the use of two-dimensional sensors and switch arrays (as shown in Figure 3, below left), but the headlamp embodiment on which Petitioner relies (which is depicted in Figure 5, excerpted below right), is illustrated as having just a single line of LEDs. See Prelim. Resp. 19–23. Alden’s Figures 3 and 5 We find this argument unpersuasive because we conclude, on the present record, that one of ordinary skill in the art (see Section II.A), would understand that Figure 5 is a schematic/sectional type of drawing intended to show generally how the system components are connected and how the LEDs would project light through the lens, and that for clarity it omits other LEDs that would be necessary to produce a two-dimensional lighting pattern. We find that the skilled artisan would recognize that a headlamp intended to produce a pattern similar to that reflected in the control circuits of Figure 3 would include additional rows of LEDs passing through the center of the lens at different angles arranged around the center of the lens. Alternatively, we conclude that one of ordinary skill in the art wishing to use a headlamp with just a single line of LEDs would understand that the sensor and/or control circuitry would need to be tailored to such an arrangement.” slip op. at 9

“previously challenged the same claims of the same patent. General Plastic, Paper 19, 16. Here, Patent Owner asserts that although Petitioner did not do so, we should consider Petitioner as having a substantial relationship to Volkswagen, which is also as a defendant in Patent Owner’s infringement suit. Prelim. Resp. 50–51. In that regard, Patent Owner relies on Valve Corp. v. Electronic Scripting Products, Inc., IPR2019-00062, Paper 11, 2 (PTAB April 12, 2019) (precedential). We do not agree, because Valve involved parties that were accused of infringement based on the same product. Valve, Paper 11, 9–10. Here, Patent Owner asserts that Petitioner is accused of infringing “based on the same type of headlight technology” (Prelim. Resp. 51), but that is insufficient. Patent Owner asserts that both parties’ accused headlights were “developed jointly with Hella KGaA Hueck & Co.” (id.), but that also is an insufficient connection for us to consider two parties substantially related for purposes of discretionary denial. As Petitioner points out, it and VW are direct competitors, and they are accused of infringing based on two different products, not as a supplier and customer of a single product, as at issue in Valve. Prelim. Reply 1. Additionally, although Patent Owner asserts that Petitioner and VW “have a history of coordinating serial IPR petitions against asserted patents” (Prelim.

Patent Owner takes the position that “classifying an object requires identifying an object and distinguishing that object among multiple classes or types of objects, such as distinguishing between vehicles, road signs, and pedestrians as described in the ’551 patent. Id. at 18 (citing Ex. 1001, 44:36–45:44, 52:66–53:4). We do not agree that the two specification passages Patent Owner cites compel such a construction. The first passage relates to a preferred embodiment that includes “a machine vision system with pattern recognition capabilities as is known in the art.” Ex. 1001, 44:37–40. The ’551 patent describes that, using known pattern-recognition methods, camera outputs “are analyzed by appropriate computational means employing trained pattern recognition techniques to classify, identify or locate the contents.” Id. at 44:63–45:3. Although the specification states that known technologies can be sued to classify an image’s contents, that does not define or restrict the understanding of what is required to “classify” an object. The second passage states that, “[u]sing color and pattern recognition techniques it is possible to determine what is a sign.” Id. at 52:66–67. To the extent that informs our understanding of “classify,” is supports a simple correlation between an image and an object. It does not include distinguishing the object among multiple classes or types of objects as Patent Owner contends.” slip op. at 11

Id. at 49–52. We do not agree that the Petition’s approach presents a problem or is hard to understand. As discussed below, we agree with Patent Owner that Petitioner has not adequately supported its obviousness contention based on Alden alone (see infra at 17 (§ II.D.2)), but that does not undermine the anticipation ground or make it difficult to understand. Accordingly, we do not agree with Patent Owner that the Petition warrants discretionary denial for lack of particularity.” slip op. at 7

“Resp. 54–59. In that regard, Patent Owner relies on Valve Corp. v. Electronic Scripting Products, Inc., IPR2019-00062, Paper 11, 2 (PTAB April 12, 2019) (precedential). We do not agree, because Valve involved parties that were accused of infringement based on the same product. Valve, Paper 11, 9–10. Here, Patent Owner asserts that Petitioner is accused of infringing “based on the same type of headlight technology” (Prelim. Resp. 55), but that is insufficient. Patent Owner asserts that both parties’ accused headlights were “developed jointly with Hella KGaA Hueck & Co.” (id. at 56), but that also is an insufficient connection for us to consider two parties substantially related for purposes of discretionary denial. As Petitioner points out, it and VW are direct competitors, and they are accused of infringing based on two different products, not as a supplier and customer of a single product, as at issue in Valve. Prelim. Reply 1. Additionally, although Patent Owner asserts that Petitioner and VW “have a history of coordinating serial IPR petitions against asserted patents” (Prelim. Resp. 56), the facts of each case are unique and we will not infer a motive from prior proceedings. Having considered Patent Owner’s arguments,8 we conclude that the first General Plastic factor weighs strongly against discretionary denial.” slip op. at 9

“Figure from Page 17 of the Akl Supplemental Declaration We find it unclear from this figure and the associated explanation in the Declaration (see Ex. 1038 ¶¶ 30–32) how the map burst and traffic burst blocks in green and blue factor in, because they cannot be received by the 2.5 MHz device. Dr. Akl testified that “McFarland teaches that necessary messages, e.g., including broadcast messages, or any other messages that need to be received by multiple nodes, ‘must be transmitted in a mode that all nodes to which they are directed are able to receive,’ that is, the base mode (e.g., the core-band).” Ex. 1038 ¶ 31 (quoting Ex. 1004 ¶ 60). He then states that one “would understand that because Hwang’s AAS_MAP_Burst_Location_IE contains system information and an index of where the MAP bursts are going to be, it is a message that needs to be received by multiple nodes, and thus is a necessary message that must be transmitted in a mode that all nodes to which they are directed are able to receive.” Id. It does not appear, however, that the blue and green blocks could be part of “broadcast messages” intended for a 2.5 MHz mobile station because they cannot be received by that mobile station. We thus do not agree that McFarland would suggest including map burst blocks in the 2.5 MHz band because they are “broadcast messages.” We also fail to see why the map burst locations would need to be received by multiple nodes, as that seems to be data that is tailored to the mobile device with which the base station is communicating.7 However, we do find it readily apparent that if the base station and the mobile station have determined to communicate using a particular bandwidth, as contemplated by the combination presented in the Petition, the map bursts necessarily would be included in that bandwidth in order for the communication scheme to be successful. The mobile station would need to” slip op. at 16

“After reviewing the evidence, we do not agree with Patent Owner’s assessment that Emerging Threats is cumulative to Stolfo, which the Examiner considered during prosecution. Patent Owner previously distinguished its claims from Stolfo by arguing, in part, that “Stolfo describes that network statistics may be used to ‘modify the decoy traffic such that it appears statistically similar to normal traffic,’” and that “Stolfo describes generating decoy traffic and not applying a transformation to existing network traffic.” Ex. 1002, 87 (quoting Ex. 2001 ¶ 124). Patent Owner also argued that “the decoy traffic used in Stolfo does not prevent an exfiltration operation[, but instead,] Stolfo explains that ‘[t]hese traps use decoy information . . . to attract, deceive, and/or confuse attackers (e.g., inside attackers, external attackers, etc.) and/or malware.’” Id. (quoting Ex. 2001 ¶ 124). In contrast, as Petitioner asserts, Emerging Threats discloses its rules to be Snort rules for preventing exfiltration. Pet. 37–43. Petitioner’s explanations of the different rules disclosed in Emerging Threats illustrate their use in preventing exfiltration, and not merely applying processes to decoy traffic. Id. Petitioner also discusses the correspondences between specific rules provided in Emerging Threats and operators disclosed in the ’343 Patent. Id. As such, we are not persuaded by Patent Owner that Emerging Threats is merely cumulative to Stolfo. Therefore, we are not persuaded that Petitioner’s combination of Sourcefire and Emerging Threats is cumulative to the art previously considered by the Examiner in the prosecution of the application that issued as the ’343 Patent, or that the proposed grounds are based on the same or substantially the same art or arguments previously presented to the Office. In conjunction with Patent Owner’s contention that Petitioner has not shown that the Office erred, we conclude that, given the circumstances presented here, Patent Owner has not demonstrated that Petitioner’s proposed grounds are based on the same or substantially the same art or arguments previously presented to the Office. As a result, we need not further consider whether Petitioner has shown error on the part of the Office. Accordingly, although we have considered Patent Owner’s request for our exercise of discretion to deny institution under 35 U.S.C. § 325(d), on the record before us, we conclude that denial of institution on that basis is not warranted. We proceed to consider the merits of Petitioner’s proposed grounds of unpatentability below.” slip op. at 17
- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner
“Weighing the evidence of the public accessibility of Emerging Threats in the relevant timeframe, we determine that Petitioner has established that Emerging Threats qualifies as a printed publication under § 102(b) for purposes of institution. The presence of the Internet Archive’s Wayback Machine copy suggests that the document was available and was accessible on December 2, 2010, prior to the March 12, 2013 effective filing date of the ’343 Patent. We have concerns that Dr. Staniford is only able to vaguely assert that the rules provided in the text document appear to be true copies of the rules that existed in 2010. See Ex. 1003 ¶ 204. Given the nature of inter partes review, however, we can be concerned only with the publication itself; we cannot rely on or inquire into how some system performed or was used in the relevant timeframe. Nonetheless, we are persuaded by Dr. Staniford’s unrebutted testimony that Snort was begun as an open source project in the late 1990s, that the Bleeding Snort project launched in 2004 as an independent clearing house for Snort rules, and that the project continues as Emerging Threats. See Ex. 1003 ¶¶ 202–203. This testimony is sufficient, for purposes of institution, to show that one of ordinary skill in the art, at and prior to the effective filing date of the ’343 Patent, would have known to look to the Emerging Threats website for Snort rules that could be applied to conventional cyber defense systems. We determine this to be a reasonable showing, at this stage of the proceeding, that Emerging Threats was sufficiently publicly accessible to be a printed publication. With respect to Patent Owner’s arguments regarding searchability of the Emerging Threats website, given its notoriety, we are unpersuaded that persons of ordinary skill in the art proceeding to the website would not have been able to search its contents and find the rules logged thereon that would have been applicable to the users’ network security concerns. Even based on Patent Owner’s presentation of the website (Prelim. Resp. 40 (citing Ex. 1030, 11; Ex. 1054)), we are persuaded that it would only have required the exercise of reasonable diligence to find the rules list, given the knowledge that one of ordinary skill would have had regarding Emerging Threats. Petitioner asserts that specific rules can be located within Emerging Threats by searching for their unique SID (Pet. 38 n.9), but persons proceeding to the website without knowledge of a specific SID would have found this to be of little help. Nonetheless, the number of locations that the rules may be located on the Emerging Threats website is still limited and users would have been able to utilize the “Last Modified” indicator, showing which directories had been modified recently, to narrow down any search, assuming that items that had not been modified for some time would be less worthy of search. As such, we are not persuaded that persons of ordinary skill in the art, proceeding to the Emerging Threats website, would not have been able to have searched its contents and find the rules contained thereon.” slip op. at 26
