      “We are persuaded and find for the reasons given that Petitioner fails to prove by a preponderance of the evidence that White teaches or suggests “receiving a bus workload for a communication bus and a first processing element workload for a first processing element based on an integrated circuit reaching a limit.” Patent Owner’s expert Dr. Brogioli testifies that “[t]he workload is a function of the demands imposed by, e.g., applications running on the system, and may or may not be subject to direct control, whereas the conditions under which that workload is processed are controlled directly.” Brogioli Decl. ¶ 66. We agree with Dr. Brogioli and find that White’s frequency and voltage monitoring and adjustments do not result in the power management logic receiving the bus workload as recited in claim element 4[a]. Id. ¶¶ 64–66. We find the testimony of Mr. Wyatt on this issue unconvincing. Wyatt Decl. ¶ 103. In support of his opinion that “monitoring the operating voltages and frequencies of the logic core 120A and common logic bridge 110 is monitoring the workload of those components,” he states: “It was well understood that operating frequency and voltage of a component reflect the activity and use, or workload, of that component.” Id. However, he does not provide any evidentiary support for this statement. We, therefore, give it little weight. See PTAB Consolidated Trial Practice Guide 40 (Nov. 2019)5 (“Opinions expressed without disclosing the underlying facts or data may be given little or no weight.”) (citing Rohm & Haas Co. v.

      “response. Paper 9. At the institution stage, therefore, Patent Owner did not dispute Petitioner’s description of a person of ordinary skill in the art or provide its own description. We regarded Petitioner’s description as consistent with the prior art before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). Thus, for the purpose of our Institution Decision, we adopted Petitioner’s proposal. Institution Dec. 12–13. In its Response, Patent Owner states that it “uses this definition” in its analysis. PO Resp. 15 (citing Brogioli Decl. ¶ 25). In view of the foregoing, for this Decision, we adopt the description of the person of ordinary skill articulated by Petitioner and used in our Institution Decision. In light of our review of the complete record, we find that this formulation is consistent with the ’494 patent and the prior art of record, and is supported by the testimony of Mr. Wyatt.

      “Post-institution, Patent Owner proposes a construction for the term “workload.” PO Resp. 15–16. Patent Owner contends that “[a] person of ordinary skill in the art would understand that in the ’494 patent, the term ‘workload’ means ‘an amount of activity over a quantum or period of time.’” Id. at 15. Dr. Brogioli’s testimony supports this construction, as does Mr. Wyatt’s. Brogioli Decl. ¶¶ 36–38; Wyatt Dep. 34:14–36:9. The ’494 patent also supports this construction. Ex. 1001, 8:20–22, 9:60–63. Petitioner does not dispute this proposed construction in its Reply. For the reasons given, we adopt Patent Owner’s construction for “workload.”” slip op. at 15

      “Nowhere does Petitioner or its expert point to an explicit disclosure in Bose of making a comparison of the claimed “bus workload and a bus workload threshold.” Instead, Petitioner relies on its expert’s opinion as to what a person of ordinary skill might have known, without any additional supporting evidence. See, e.g., Pet. 26 (“[A person of ordinary skill] would have understood global PMCU compares a workload threshold as exemplified by the predicted power and performance of each power mode and the monitored workload to select and adjust the power mode of a component” (citing Wyatt Decl. ¶¶ 54–55)). This opinion is not supported by the record. The only disclosure of a comparison in Bose that we have been shown is the comparison of PowerTotal to PowerMax in step 303 of Figure 3, which Petitioner does not rely on to meet the “comparison” limitation in the claim. Hearing Tr. 17:16–20. Also without proper support is Petitioner’s assertion that “a [person of ordinary skill] would have understood that in Bose, selecting or adjusting power mode for a component entails comparing a workload threshold, such as predicted power and performance associated with each power mode with real time statistics, such as the monitored workload of a component.” Pet. 26 (citing Wyatt Decl. ¶¶ 55–56). We determine that for the reasons given, Petitioner fails to demonstrate by a preponderance of the evidence that the claimed comparison element 1[g] of claim 1 is taught or suggested by Bose. We find, therefore, that Petitioner has not demonstrated that claim 1 is anticipated by Bose, nor has Petitioner demonstrated that to a person of ordinary skill, claim 1 would have been obvious in light of Bose.” slip op. at 25

      “The two proposals are materially similar in the education requirement, but differ marginally in professional experience required (three versus five years). See supra. While we were persuaded, on the preliminary record, that both Petitioner’s and Patent Owner’s proposals were consistent with the problems and solutions in the ’202 patent and the prior art of record, on balance, we determined that Petitioner’s proposal was a better reflection of the level of skill in the prior art, and we therefore adopted it for our Institution Decision. See Institution Dec. 12–13. For this Decision, we adopt the description of the person of ordinary skill articulated by Petitioner and used previously in our Institution Decision. In light of our review of the complete record, we find that this formulation is consistent with the ’202 patent, the prior art of record, and is supported by the testimony of Dr. Baker.

      “requirement.” Pet. Reply 5. We do not agree with Petitioner. We find that the language of the claims supports Patent Owner’s argument that the desired signal and the interferer signal are received together. As discussed infra, claim limitations 7.7 and 7.8 recite determining a signal strength of the interferer signal and determining a signal strength of the desired signal. These determinations must be performed at the same time; otherwise, the determinations of signal strengths would not be of the same wireless signal. See Larson II Decl. ¶ 70; Baker II Decl. ¶¶ 48–49 (explaining that consideration of signal strengths detected at the same time would be “essential”). The specification of the ’202 patent further supports this finding: “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:22–24; see also Figs. 2A, 2B (showing interferer signals and desired signals together).” slip op. at 17

We find that whether claim 1 requires the packets intercepted by the network appliance in limitation 1a to be the same packets involved in limitations 1b–1d, Petitioner has not persuasively shown that any same number of packets in Athas that are received at proxy platform 101 are then modified and forwarded as required by limitations 1b–1d, for the reasons discussed below. We agree with Patent Owner that the number of packets in limitations 1b-1d are the same, and, therefore, we find that Petitioner’s citations to Athas do not disclose the sequence of operations recited in claim limitations 1b–1d. Petitioner, therefore, does not demonstrate that Athas anticipates the claim. Specifically, we are not persuaded either by Petitioner’s assertions or Dr. Williams’s testimony that in Athas, the same “number of packets” that are received and modified by Athas’s proxy platform 101 are then forwarded to Athas’s proxy client 107, as required by limitations 1b–1d.

The definite article “the” can be used to modify something plural, e.g., “the digital representations.” Although in claim 1, “the” is used to modify a “digital representation,” that does not help the Patent Owner, because nothing in the claim excludes the involvement of additional digital representations while one “digital representation” is analyzed. Patent Owner points to nothing in claim 1 which restricts the analyzing to “only” one digital representation or “no more” than one digital representation, and we see none. Further, claim 1 uses the non-limiting phrase “comprising,” which creates a presumption that the claim is not limited to only those elements expressly recited in the claim. Crystal Semiconductor Corp. v. TriTech Microelectronics Int’l, Inc., 246 F.3d 1336, 1348 (Fed. Cir. 2001).

      “Tempered against Petitioner’s evidence of an alleged motivation to combine MR810, Gradon, and Edirisuriya is the uncertainty of operability of the proposed combination. With respect to each of the proposed circuit designs that Petitioner contends a skilled artisan would have been aware of to implement the combined teachings, a skilled artisan would have been faced with the real-world fact that there was uncertainty as to the operability of the design. First, the circuit designs that Petitioner proposes a skilled artisan would have utilized are not based on disclosure in the prior art. See Pet. Reply 5–7; Ex. 1032 ¶¶ 13–22.

Co. v. United States, 702 F.2d 1005, 1012 (Fed. Cir. 1983))). All of the circuit designs Petitioner proposes a skilled artisan could have used to implement the asserted combination are hindsight reconstructions based on the disclosure in the ’641 patent. The ’641 patent describes switching the heater wire between two modes of use— carrying temperature measurement signals and heating the gas delivery tube —by inserting a component in parallel with a temperature measuring thermistor to switch the current path of the heater wire between the thermistor and the parallel-connected component. Specifically, the ’641 patent discloses switching the current flowing in heater wire 21, 28 between the parallel paths of thermistor 23 and diode 22, depending on whether heater wire 21, 28 is being used to carry temperature measurement signals or heat gas delivery tube 3, respectively. Ex. 1001, 4:8–21. Each of Petitioner’s proposed circuits, drawn solely from the testimony of Mr. Bath and not supported by the prior art, has a similar purpose. Petitioner’s first proposed circuit contains a capacitor connected in parallel with a thermistor to switch the path of the heating wire current between the thermistor, when the heating wire is being used to carry temperature measurement signals, and the capacitor, when the heating wire is being used to heat the breathing tube. Ex. 1032 ¶¶ 15–16. Petitioner’s second proposed circuit contains a gate-todrain connected MOSFET connected in parallel with a thermistor to switch the path of the heating wire current between the thermistor, when the heating” slip op. at 25

The Specification also states that “the present invention operates by replacing original function calls with substitute function calls within the content, at a gateway computer, prior to the content being received at the client computer.” Id. at 4:5760. From such examples, we understand the Specification to use the phrase “function call” in the same sense that the claims recite in the phrase “call to a [] function.” That is, a “call” is part of the recited “content,” as a statement or instruction containing the function that, when executed, causes the function to provide a service. Thus, we find the dictionary definition of the term “function call” applicable here and indicative of the meaning of the term to a person of ordinary skill in the art.” slip op. at 7

      “[w]hile replies can help crystalize issues for decision, a reply that raises a new issue or belatedly presents evidence will not be considered and may be returned. The Board will not attempt to sort proper from improper portions of the reply. Examples of indications that a new issue has been raised in a reply include new evidence necessary to make out a prima facie case for the patentability or unpatentability of an original or proposed substitute claim, and new evidence that could have been presented in a prior filing. Trial Practice Guide, 77 Fed. Reg. at 48767; see also Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1080 (Fed. Cir., 2015) (discussing that a patent owner “is undoubtedly entitled to notice of and fair opportunity to meet the grounds of rejection.”). With these guidelines in mind, we are persuaded that the above-identified argument in the Reply should not be considered in deciding this matter. As stated above, the Petition relies on Ross’s “hook functions within a hook script” as teaching or suggesting the “call to a first function.” Pet. 1718. Although the Petition relies on the understanding of a person of ordinary skill in the art when explaining Ross’s handling of the hook function, Petitioner does not assert in any meaningful way that Ross’s use of hook functions in the hook script would be modified to include calls to additional hook functions that Ross does not describe. Nor does Petitioner explain in the Petition that Ross would be modified to replace the assignment instruction with a call to the hook function. The arguments in the Reply are not explanations of how Ross’s hook functions, as taught by Ross, may be understood to include the recited “call to a first function,” as asserted in the Petition. Rather, the argument that a “call” may be added to either the security check or the hook script is an alteration of Ross, necessitated because Patent Owner correctly argues that Ross fails to teach or suggest the limitation. The contention that Ross’s embodiments would be modified, altered, or imbued with details not present in Ross is a new contention, necessary to make a case for the unpatentability of the claims, and should have been presented in the Petition. To consider the argument would unfairly prejudice Patent Owner who, after having argued there is a significant gap in Petitioner’s case, would be left without an opportunity to respond substantively to the new arguments and support its rebuttal with additional evidence, if necessary. Accordingly, we do not consider the improper arguments identified above.” slip op. at 20

      “Patent Owner’s expert Dr. Medvidovic disagrees with Dr. Rubin’s opinion that instrumentation can occur in many hosts. Ex. 2002 ¶ 71. His testimony is unconvincing, however. Dr. Medvidovic does not address Dr. Rubin’s assessment that Khazan teaches instrumentation on a host that is different from the host that executes the wrapped function. Instead, Dr. Medvidovic asserts that Khazan does not disclose applications received through a network. Id. Further, Dr. Medvidovic opines that Khazan addresses viruses that infect applications resident within a computer’s file rather than in content received over a network. Id. We find that Dr. Medvidovic’s statements do not address Petitioner’s contention and ignore relevant teachings of Khazan. For instance, Khazan teaches that each host accesses information stored in data storage devices using a network (communication medium). Ex. 1003 ¶ 33. And any of Khazan’s components—e.g., static analyzer, dynamic analyzer, libraries, application executable, etc.—may be stored in the data storage system. See id. ¶ 72 (describing Figure 4A, which also lists the various lists 106, 111, 112). Therefore, we do not agree with Patent Owner’s narrow assessment of Khazan, which would limit application of Khazan’s techniques exclusively to a file resident in the host, rather than on content received over a network. Indeed, Khazan expressly discloses an embodiment in which instrumentation is performed “before invocation of the application” allowing for the instrumented library (or application) to be stored on a storage device. Ex. 1003 ¶ 75. That storage device, as discussed above, is accessed via a network. Accordingly, it is reasonable to conclude, and we find that, Khazan teaches or suggests that any host may receive over the network (communication medium 18) instrumented applications or libraries for processing at the host.” slip op. at 36

Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
