“III. ANALYSIS LEVEL OF ORDINARY SKILL A. Petitioner explains the applicable level of skill in the art as follows: As of June 24, 2010, a person of ordinary skill in the art (POSITA) would be a person having a bachelor’s degree in computer science, computer engineering, or an equivalent, as well as two years of industry experience and who would have had a working knowledge of software security analysis, and dynamic malware analysis. Additional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education. Pet. 8 (Ex. 1003 ¶¶ 30–31). Patent Owner does not dispute Petitioner’s explanation of the level of skill in the art. See Ex. 2031 ¶¶ 15–16. We adopt Petitioner’s uncontested proposed level of ordinary skill in the art, which we find consistent with the level of ordinary skill in the art reflected by the ’872 patent and the prior art of record. See Okajima v.” slip op. at 12

“We begin with the claim language in view of the Specification, which weighs heavily against Patent Owner’s position that we should rewrite “computer system” as narrowly referring to a “computing device.” PO Resp. 24. As Petitioner notes, the ’872 patent’s Specification uses “computer system” to refer to a wide range of equipment, from a component of a computing device, to a whole computing device, to a collection of computing devices. Reply 9–10 (citing Ex. 1001, 4:5–8, 11:15–18, 16:50–55). In one example, the Specification refers to “one or more other computer systems (e.g., protected network devices 136).” Ex. 1001, 18:52–53. Thus, the Specification lists “protected network devices 136” as only an example of “other computer systems,” demonstrating that “computer systems” refers to things other than protected network devices. Although Patent Owner may be correct that this passage more than a single computing device,” we find that other disclosures in the ’872 patent do. Specifically, the Specification uses the language “distributed computer system” when referring to numerous components, including “protected network devices” and an “IDS/IPS system.” Ex. 1001, 3:26–28; Reply 10. In addition to showing that a “computer system” is not limited to a single computing device, this conveys that a “computer system” according to the ’872 patent can include an IDS/IPS.” slip op. at 14

“Based on our review of the complete record, we find Petitioner’s arguments and evidence to be more persuasive. Patent Owner does not dispute Petitioner’s argument and evidence that capturing detailed information like Goel’s activity sources, activity targets, and association was recognized as enhancing threat analysis. Pet. 44 (citing Ex. 1003 ¶ 79); see PO Resp. 55–59; Sur-Reply 15–17. Additionally, contrary to Patent Owner’s suggestion, we find that the Petition does not propose incorporating Goel’s kernel hooks into Capalik’s system. See Pet. 41–46. Patent Owner contends that the Petition’s reference to modifying Capalik by “adding lines of code” suggests implementing the code disclosed in Goel include kernel hooks. Id. Notwithstanding Patent Owner’s assertion otherwise, this is an unpersuasive bodily incorporation argument, as the Petition never says an ordinarily skilled artisan would have used the exact lines of code from Goel in Capalik. Rather, the Petition says that an ordinarily skilled artisan would have had sufficient skill to implement straightforward code modifications to identify activity sources, targets, and associations: a [person of ordinary skill in the art] would have understood that modifying Capalik’s system (e.g., Linux-based) to additionally monitor, identify, and store each individual activity of an attack including “activity sources, activity targets, and associations” would have required straightforward modifications to programs/code instructions, which would have been well-within the skillset of a [person of ordinary skill in the art]. Pet. 46. Patent Owner argues that Petitioner does not explain how an ordinarily skilled artisan would have modified Capalik without using kernel hooks. Sur-Reply 17. But Patent Owner does not cite any evidence to counter Dr. Jakobsson’s testimony that an ordinarily skilled artisan would have had the skill to apply Goel’s general teaching of identifying sources, targets, and associations to Capalik’s system. Ex. 1003 ¶ 182. On the whole, the evidence does not support Patent Owner’s position that the combination would have required substantially increased detection risk. Moreover, even if the combination would have somewhat increased detection risk, Petitioner persuades us that an ordinarily skilled artisan still would have had reason to combine the references teachings. Patent Owner’s allegations of increased detection risk do not negate the undisputed evidence that the combination would have provided the advantage of improved threat analysis. Pet. 44 (citing Ex. 1003 ¶¶ 175–182). Ultimately, Patent Owner’s that activity logging be undetectable.” PO Resp. 56 (emphasis added) (citing Ex. 1004 ¶ 6). This exaggerates Capalik’s disclosure. Although the cited paragraph suggests that certain systems unfortunately may be detectable by some users, it does not convey that it is a requirement for the system to be categorically undetectable. See Ex. 1004 ¶ 6.8 In sum, Petitioner persuades us by a preponderance of the evidence that it would have been obvious to modify Capalik “to identify and store unauthorized activities including the activity source, activity target, and association of each activity.” Pet. 41–46; PO Resp. 55–59; Reply 20–22; Sur-Reply 15–17.” slip op. at 47
- Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for patent owner
“arguments and evidence, we determine that Patent Owner fails to sufficiently show a nexus between any of its objective indicia evidence and the claimed invention. See Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (“The patentee bears the burden of showing that a nexus exists”). A showing of sufficient nexus is required to establish that the evidence relied upon traces its basis to a novel element in the claim, not to something in the prior art. Institut Pasteur & Universite Pierre Et Marie Curie v. Focarino, 738 F.3d 1337, 1347 (Fed. Cir. 2013). Objective evidence that results from something that is not “both claimed and novel in the claim” lacks a nexus to the merits of the invention. In re Kao, 639 F.3d 1057, 1068 (Fed. Cir. 2011) (emphasis omitted). Thus, establishing nexus involves a showing that novel elements in the claim, not prior-art elements, account for the objective evidence of nonobviousness. Id. As discussed above, Petitioner shows that Capalik teaches all limitations of claim 1. Petitioner persuades us that none of claim 1’s elements individually nor any combination thereof is novel over Capalik’s disclosure. Accordingly, claim 1 is not novel over Capalik, which disproves Patent Owner’s assertion of nexus. PO Resp. 73–76. Moreover, even if claim 1 were novel, Patent Owner otherwise fails to show nexus for its commercial success, praise, or copying assertions. Patent Owner’s evidence does not show that Petitioner’s commercial product embodies claim 1. For example, we agree with Petitioner that Patent Owner “failed to analyze any meaningful detail regarding” how the Falcon Platform allegedly meets limitation 1(d). Reply 28–29. In particular, Patent Owner has not sufficiently addressed limitation 1(d) with the following argument: “1[D] The Falcon Platform transmitted to other computer systems” slip op. at 37

“We disagree. Although claim 1 recites step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Here, nothing in the express claim language precludes performing step 1d before step 1b. The claim does not expressly recite signaling the device(s) previously “identified as available.” Nor does the claim otherwise specify that step 1b must precede step 1d. For example, the claim does not contain temporal terms like “then,” “next,” or “further.” Although Patent Owner points out that a term of step 1d (i.e., “the” one more available devices) derives antecedent basis from step 1b, this alone does not require performing step 1b before step 1d. PO Resp. 5, 10; Sur-reply 11. Rather, we agree with Petitioner that step 1d’s reliance on step 1b for antecedent basis only serves to clarify that the steps refer to the same device(s), not to determine the performance order. Reply 4, 5. We also agree with Petitioner that claim 1 inconsistently employs antecedent basis for other claim elements, which undermines Patent Owner’s argument that step 1d’s antecedent basis establishes a specific order.

“We disagree. Petitioner met its burden to show that the combination would have been obvious. Zhang teaches a cellular phone (which logically receives cellular calls) and routing media to audio devices on its network. Ex. 1004, 3:25–29. Missing in Zhang is an explicit teaching that its cellular calls (as opposed to other media) are routed. Pasanen explicitly teaches routing cellular calls to networked audio devices. Ex. 1006; 4:20–37. Taken together, routing Zhang’s cellular calls across its network would have been obvious to a POSITA. Patent Owner’s argument that Zhang-Fillebrown’s 802.11 or HomeRF network do not support routing cellular calls discounts Zhang’s teaching that “its network can be built on top of many different kinds of communication media” including but not limited to 802.11 and HomeRF, as well as the “optional HomeRF features” Petitioner claims would sufficient to implement the claimed functionality. Ex. 1001, 4:46–50; Reply 20–22 (citing Ex. 1037 ¶¶ 13–15); Sur-reply 3–6 (arguing that HomeRF’s isochronous mode and DECT protocol are optional and would not have been necessary to practice Zhang’s subject matter). And though Zhang does not discuss transcoding or specific HomeRF features/protocols, which Patent Owner argues are necessary for routing cellular calls across Zhang’s 802.11 or HomeRF network, we agree with Petitioner that the ’648 patent also provides scant technical details as to how its system routes cellular calls over its local network, suggesting that such was well known at the time.

“Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine.

Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts.

When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim. 37 C.F.R. § 42.108(a). Applying those standards, and upon consideration of the information presented in the Petition, Preliminary Response, and supplemental briefing, we determine that Petitioner has demonstrated a reasonable likelihood of success in proving that at least one of the Challenged Claims is unpatentable. See 35 U.S.C. § 314; 37 C.F.R. § 42.4(a). Accordingly, we institute an inter partes review as to all Challenged Claims of the ’868 patent on all relevant grounds raised in the Petition.” slip op. at 2

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). Neither party argues, at least at this stage of the proceeding, that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’868 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan (Ex. 1012 ¶ 20), we apply the level of skill set forth above.” slip op. at 8

“Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (stating that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))). Petitioner submits that “all claim terms should be given their plain and ordinary meaning” (Pet. 10–11), and “Patent Owner agrees” (Prelim. Resp. 4). In determining at this stage of the proceeding that Petitioner has demonstrated a reasonable likelihood of establishing unpatentability of at least one challenged claim (namely dependent claim 11 in this case), we need not and do not construe expressly any claim terms. Nevertheless, we encourage the parties to submit proposed constructions for the limitation “determining a UE [i.e., User Equipment] environment information,” as recited in dependent claim 11. See Ex. 1001, 49:12–15, 1:40–42 (emphasis added). To the extent that a party proposes that this limitation should have its ordinary and customary meaning, the party should submit and explicitly identify such meaning. O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”). For example, the parties should discuss (a) the meaning and scope of “determining” as used in the subject limitation; (b) the meaning and scope of “environment information” as used in the subject limitation; (c) any relationship or overlap between “environment information” and “link quality positioning information,” as recited in dependent claims 7 and 11 (see Ex. 1001, 48:62–65, 49:12–15); and (d) whether UE “environment information” includes location or orientation of the UE.” slip op. at 10

“Petitioner contends the skilled artisan would have had rational reasons to combine the teachings of Jarvinen and Fox to arrive at the invention of dependent claim 11 (which includes the features of independent claim 1 and dependent claim 7) and would have had a reasonable expectation of success in doing so. Pet. 37–41; see, e.g., id. at 38 (“[The skilled artisan] faced with the problem of estimating a UE’s future link quality at a location would have looked to Fox because Fox solves the problem of estimating future link quality with the exact same information available to Jarvinen.”); Ex. 1012 ¶ 70 (Dr. McClellan testifying that “[a]ll of the data upon which Fox relies is already disclosed and linked together in Jarvinen’s database, and it would have been obvious for [the skilled artisan] to combine Fox’s method of looking up previous link quality to estimate future link quality with Jarvinen’s teachings.”); ¶ 72 (Dr. McClellan testifying that “modifying Jarvinen to perform Fox’s link quality estimation would have constituted a simple substitution of a known element to yield predictable results.”). Patent Owner does not dispute such reasons or expectations at this stage of the proceeding. For the reasons and evidence set forth in pages 37–41 of the Petition, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox to arrive at the invention of claim 11, and to do so with a reasonable expectation of success. c) Summary At this stage of the proceeding and based on the record before us, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox with a reasonable expectation of success, and sufficiently supports Petitioner’s contention that dependent claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox. Thus, for the foregoing reasons and those stated in Petitioner’s preliminary briefing (Pet. 17–47, 50–51, 54), we determine that Petitioner has established a reasonable likelihood that it would prevail in showing that claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox.” slip op. at 18

“Given the deficiencies outlined above, Petitioner has not shown that the prior art teaches or suggests creating a fingerprint at the virtual machine monitor as the challenged claims require. Thus, Petitioner has not shown a reasonable likelihood of prevailing with respect to at least one of the challenged claims. III. CONCLUSION After considering the evidence and arguments presented in the current record, we determine that Petitioner has not demonstrated a reasonable likelihood of success in proving that at least one of the challenged claims of the ’697 patent is unpatentable. We therefore do not institute trial on any challenged claims or grounds raised in the Petition.” slip op. at 10

“We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. Sur-reply 1–2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter. Sur-reply 1–2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Last, Petitioner’s characterization of Patent Owner’s infringement allegations in the related district-court proceedings, even if correct, do not undermine the claim’s plain language.” slip op. at 9

“Patent Owner argued that we should not institute both petitions. Paper 8, 1–5. Patent Owner argued that the challenged claims are not long and Petitioner’s concerns about the construction of “association” in limitation 1(b) are “contrived.” Id. at 1. Patent Owner contends that Petitioner could have addressed all of the challenged claims in one petition. Id. Noting that both the ’70 petition and the instant Petition challenge all claims of the ’872 patent, Patent Owner argued that the number of claims challenged does not necessitate multiple petitions. Id. at 2–3. Patent Owner also argued that Petitioner could have waited until closer to the statutory due the claim language “association” in the related district court proceeding. Id. at 4–5. Considering the facts holistically, we determine the totality of the circumstances here supports Petitioner’s position that two petitions are warranted. Petitioner has challenged a large number of claims directed to complex subject matter. And the task of challenging those claims is complicated by the potential for Patent Owner to argue for a narrow construction of “association” in limitation 1(b). Patent Owner’s suggestion that Petitioner would not have needed to file multiple petitions if it had waited longer to file a petition is not persuasive. Paper 8, 4–5. Patent Owner does not explain why a petitioner should be encouraged to delay the filing of its petition. See id. And the parties appear to agree that Patent Owner has not weighed in on whether “association” should be interpreted narrowly or broadly. Prelim. Reply. 8; Prelim. Sur-Reply 8.
