“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.

“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.

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.

“Riskey discloses “said sensor signal varies based on a corresponding change in one or more physiological parameters of said ruminant animal” (limitation 5[B]). We find Riskey’s description of temperature sensors to be persuasive evidence on this issue. Riskey discloses sensors for measuring changing animal characteristics, e.g., temperature, over time. Ex. 1005 ¶¶ 35, 44; see also id. ¶¶ 75, 76 (detecting temperature changes). We further credit Dr. Young’s testimony that one skilled in the art would understand that generated sensor signals, e.g., temperature, would change over time, whereby the sensor signal varies based on any corresponding change in the ruminant physiological parameter that the signal represents. Ex. 1002 ¶¶ 84, 85; see Cont’l Can Co. USA v. Monsanto Co., 948 F.2d 1264, 1269 (Fed.

We consider Dr. Kan’s testimony that Riskey is silent as to details about the sensor signal, but are not persuaded because the testimony appears to contradict Riskey’s disclosure of a bolus including sensors for monitoring changes in animal characteristics, generating animal characteristic messages, i.e., signals, and wirelessly transmitting data corresponding to the monitored characteristics. See Ex. 2006 ¶¶ 170–174; Ex. 1005 ¶¶ 25, 63, 67, 68, 75–78, 101.

“The ’750 patent states that “the fluid pathway can be a radially serpentine fluid pathway which causes the fluids received in the off axis chamber to flow back and forth around a radius of the off axis chamber,” also using “radially serpentine fluid pathway” to refer to this rotation around the chamber radius “while also traversing a length of the off axis chamber.” Ex. 1001, 4:34–41 (emphasis added). This is the only description of “radially” serpentine flow in the ’750 patent. Notably, the ’750 patent does not use “radially” or “serpentine” to describe a fluid pathway “which causes the fluids to spiral around the central chamber within the off axis chamber along a length of the off axis chamber,” instead referring to such a fluid pathway as a “helical fluid pathway.” Id. at 4:41–44. See CAE Screenplates, Inc. v. Heinrich Fiedler GmbH & Co. KG, 224 F.3d 1308, 1317 (Fed.

We explained that the flow path depicted above, which is equivalent to that of Figure 14 of the ’750 patent, “flows circumferentially about the central chamber.” Id. at 14. We maintain this interpretation. Stated differently, the depicted flow is around a longitudinal axis of the chamber.

The flow is not around a radius of the chamber, which Patent Owner recognizes is required for a flow path to be radially serpentine. See PO Resp. 10 (“Patent Owner agrees with the Board’s conclusion in the [Institution Decision] that ‘radially serpentine’ as recited in the claims of the ’750 patent means a back and forth flow around a radius of the off axis chamber.” (citation modified)); PO Sur-reply 2 (agreeing that “radially serpentine” requires “a back and forth flow around a radius of the off axis chamber”).” slip op. at 14

“We agree with Patent Owner that neither Petitioner nor its witness, Mr. Nixon, has explained adequately how Thurler’s disclosure of its tube e being perforated for two thirds of its length “contemplates other lengths of perforations.” See Pet. 48; Ex. 1013 ¶ 212. Such conclusory assertions fail to apprise us of why an ordinarily skilled artisan would have been motivated to modify Thurler’s device in contradiction to Thurler’s explicit disclosure. We are also not persuaded by Petitioner’s proffered reasoning for modifying Thurler’s device. First, the modification is not a matter of design choice because the perforations allow the gases generated by firing the projectile to pass into the space between tubes e and g where they partially expand. See Ex. 1015, 1:84–91. Thus, modifying the number of perforations necessarily affects the flow of gases through the device. Next, neither Petitioner nor Mr. Nixon explains adequately how reducing the amount of perforation in tube e results in an increased fluid length. See Pet. 49; Ex. 1013 ¶ 213. Rather, although less fluid may enter into tube e with Petitioner’s modification, it appears that that fluid would travel the same distance along tubes e and h as in Thurler’s unmodified device. Finally, neither Petitioner nor Mr. Nixon explains adequately how limiting the amount of gases generated by firing the projectile from entering the expansion zones of tubes g and h provides any benefit. To the contrary, limiting the amount of gases in the manner suggested by Petitioner would reduce the suppression of such gases, resulting in a less effective device. Moreover, Thurler discloses that “there is still a space of a few millimeters between [tubes] e and g which is necessary” to prevent the application of “pressure on the projectile causing the same to deviate.” Ex. 1015, 1:106–2:3. Thus, Petitioner’s modification would not result in the passage of gases occurring only at the first three of Thurler’s tubular sleeves as asserted by Petitioner. Additionally, in the Institution Decision, we explained that Petitioner did not provide adequate reasoning to support the proposed modification of Thurler’s device regarding parent claim 1 to have concentric tubes around the central tube e. See Inst. Dec. 29–31. This shortcoming, which we maintain, carries through to dependent claim 6. Accordingly, for the foregoing reasons, Petitioner has not shown, by a” slip op. at 26

“We agree with Petitioner that the amendment is broadening. Petitioner’s witness testified that he “wouldn’t call a BB gun a high energy device or a high energy weapon.” Paper 33, 18:4–6. Thus, per Petitioner’s witness, use of a BB gun would not be covered by claim 22, no matter what is discharged from the BB gun. However, if high energy material is discharged from that same BB gun, that use would be covered by proposed substitute claim 43 (assuming the other claim recitations were met). See id. at 21:10–12 (Dr. Neitzel agreeing that “if something produces a high energy material, it automatically is a high energy weapon”). Thus, by deleting “high energy device” and replacing that language with “weapon,” proposed substitute claim 43 impermissibly broadens the scope of claim 22. See Sisvel Int'l S.A. v. Sierra Wireless, Inc., 81 F.4th 1231, 1241 (Fed. Cir. 2023) (“But if a substitute claim ‘is broader in any respect it is considered to be broader than the original claim even though it may be narrower in other respects.’” (citation modified) (quoting Hockerson-Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed.

“On the full record, we find that a preponderance of the evidence supports Petitioner’s argument that one skilled in the art would have been motivated to combine Li and Siam to reduce total power consumption including idle power consumption (Li) and circuit power consumption (Siam). Both Li and Siam describe a need for reducing energy consumption in wireless devices. See Ex. 1005 ¶ 18; Ex. 1006, 875–76. Both references further describe switching from MIMO mode to another operating mode to reduce power consumption and optimize battery life. See Ex. 1005 ¶ 19; Ex. 1006, 875 (“[W]e dynamically adjust the ‘transmission mode’ . . . so as to minimize the total energy consumption.”). In sum, the references teach the same technique, i.e., mode switching, to achieve the same goal, i.e., reducing energy consumption, in similar devices, i.e., wireless devices. See KSR, 550 U.S. at 417 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would unless its actual application is beyond his or her skill.”). Accordingly, we are persuaded by Petitioner’s argument and evidence that one skilled in the art would have combined the Li and Siam with a reasonable expectation of success in doing so.

“We agree with Petitioner that the Specification supports construing “selection” as including inputs to a user interface, thereby “assigning” a client to a provider within the system. For example, the Specification describes a user interface including selection components. Ex. 1001, 10:45– 48 (“the user interface . . . may display . . . selection or display components”), 12:19–22 (authorized users may make selections by doubling tapping a touchscreen). The Specification further discloses that the “administrators may have complete access to the service providers and the clients to assign the clients to individual service providers through the user interface.” Id. at 11:13–18 (reference numerals removed, emphasis added). Taken together, we agree with Petitioner that assigning clients in response to selections of a user interface is consistent with the plain and ordinary meaning of the claims and the Specification. We decline to read Patent Owner’s additional limitations of “deliberate and active choice” into the claim, because these additional limitations lack support both in the claim language and the Specification. We do agree with Patent Owner’s argument that assigning and selection must be distinct elements, because they are separately listed and assigning happens in response to selection(s).” slip op. at 9

“Patent Owner responds that “Petitioner does not identify any selection made by Douglas’s administrator which may result in assignment of a provider.” PO Resp. 15 (citing Pet. 19–20; Ex. 1002, 6:33–7:13, Fig. 2). First, Patent Owner construes “selection” as “a deliberate and active choice by an administrator,” and argues that “Douglas discloses no such selection.” Id. at 15–16 (citing Ex. 1001, 11:13–18; Ex. 2005 ¶ 66). Instead, “Douglas’s administrator merely inputs pre-determined information from the prescription form” that the physician provided and thereby selected. Id. at 16 (citing Ex. 1002, 6:33–7:13, Fig. 2; Ex. 2005 ¶ 67). We find this argument not commensurate with the claim scope. As discussed above in claim construction, we decline to read Patent Owner’s additional limitations of “deliberate and active choice” into the selection limitation as lacking support both in the claim language and the Specification. Supra, Section III.C.1. Second, Patent Owner argues that Douglas does not teach assigning “in response to” an administrator’s selection. PO Resp. 16–17. Instead, Patent Owner argues that Douglas’s “information entered by the case advisor was provided by the physician.” Id. (citing Ex. 1002, 6:33–7:16). Again, we find this argument not commensurate with the claim scope, as the claim does not require a single assignment of client to provider. In other words, even if Douglas’s prescription information qualifies as a first assignment of client to provider, Douglas teaches the administrator using the same information to assign the client to a provider within the system, thereby meeting the required claim limitation.” slip op. at 16
