“We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices. Tr. 38:3–39:1 (counsel agreeing that one would need to access the area behind splice tray 230 in Holmberg, albeit in “rare occasions”); Ex. 1003 ¶¶ 90–92; Ex. 1033 ¶¶ 7–8. Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray. Pet. 41 (citing Ex. 1005 ¶ 39 (disclosing that a rotatable splice tray or shelf would “provide[] full and convenient access to the splice tray”)). First, Petitioner and Dr. Kiaei persuasively demonstrate that once the fibers of Holmberg are routed from behind splice tray 230 and the distribution cables spooled on this tray, a technician could not reasonably access fiber optic cables stored behind splice tray 230 without releasing or opening splice tray 230. Pet. Reply 14–15 (citing Ex. 1023, 60:20–61:15); Ex. 1033 ¶¶ 31–32. Second, Petitioner persuasively demonstrates that without a hinged connection, the technician would have to either hold the splice tray of Holmberg with one hand while performing the necessary routing and splicing steps, two screws would need to remain in place (essentially replicating a hinge), or the tray would have to be left to dangle, supported only by the routed and spliced fibers.

“Allegedly New Arguments on Reply Patent Owner contends that Petitioner’s arguments regarding the benefits of a hinged connection when performing the splicing and routing steps should be dismissed or ignored because they were improperly raised for the first time on reply. Sur-reply 19–20. We disagree. The Petition asserts that one of ordinary skill in the art would have sought to add a hinged connection, such as that disclosed in Battey, in Holmberg and would have seen a benefit to so doing.

“Patent Owner’s arguments do not persuasively undermine Petitioner’s position. Sakamoto expressly discloses setting the ratio of negative to positive electrode active material in the range of 1.05 to 1.30. Ex. 1005 ¶ 8. Sakamoto also explains why this range is preferable, i.e., if the ratio is roughly equal “the charge-discharge cycle performance is insufficient due to significant deterioration from charging and discharging,” and if the ratio is 10 Citations to the prosecution history of Yamaki are to the page numbers added to the lower right corner of the document. too high “too much of the compound does not participate in charging and discharging.” Id. ¶¶ 6, 8.

Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Rather, Sakamoto warns against setting the reversible capacities of the positive and negative electrode substantially equal as this may result in excess lithium plating on the surface of the electrode.

“art would not have modified Kurita in view of Lemoff because Lemoff positions the signal emitters near the fiber to emulate WDM without the need for an external optical multiplexer or a similar device and discourages using optical wavelength multiplexers for short distances because the complexity of the design is often cost prohibitive (PO Resp. 47–48), Lemoff does not appear to limit the usefulness of the fiber connector to any particular optical signal transmission distance. Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.... Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art” (In re Keller, 642 F.2d 413, 425 (CCPA 1981)).

“stopped single optical fiber because fixing it in place does not passively align it with the optical components (PO Resp. at 35–37) is not persuasive because fixing Kurita’s fiber (40) in place in accord with Lemoff’s teaching regarding the ferrule (255) inserted until being stopped by the receptacle (260) (Ex. 1006, 5:50–6:15, Fig. 2) would align Kurita’s optical array (20), and lens (30)) (Ex. 1004 Fig. 3) passively in the same manner that Lemoff’s ferrule (255), after being inserted until stopped by the receptacle (260), passively aligns the optical fiber (250) with the optical components (optical imaging element 220 and light emitters within emission apertures 120) (Ex. 1006, 5:50–6:15, Fig. 2; Reply 15–16). Regarding Patent Owner’s argument that the light from each of Kurita’s lasers (11) depicted in Figure 3 cannot pass through a separate focusing lens (30) pie shaped sector because the lasers (11) and collimating lenses (21) are arranged linearly rather than being arranged about a circular axis (PO Resp. at 37–42), we do not agree. Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38). Kurita meets those claim requirements. Kurita’s two by two array (10A) of lasers (11), collimating lens (21) array (20), and focusing lens (30) are shown in Kurita’s Figure 3 (cropped) as follows: The image is a portion of Kurita’s Figure 3 showing Kurita’s laser array, collimating lens array, and focusing lens (30).

“We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged.

“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.

“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.

“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

“We decline to “throw out” Dr. Horst’s testimony for several reasons. First and foremost, Patent Owner has not moved or otherwise sought to exclude his testimony, or even filed an objection. Hearing Tr. 46:19–47:1. Thus, the issue of whether the testimony should be excluded is not properly before us. Further, Petitioner asserts that “[t]his distinction is irrelevant.” Pet. Reply 2. We agree. Patent Owner has not pointed to any opinion by Dr. Horst that turns on the alleged “flaw” in the definition of the person of ordinary skill. Id. at 46:19–48:3. Finally, there is no prejudice. Patent Owner’s expert used the definition proposed by Patent Owner in his analysis. See Brogioli Decl. ¶ 25. Nor could Patent Owner show us with specificity any place in the record where resolving this dispute would make a difference in this case. Hearing Tr. 46:3–47:3.

“operating system.” PO Resp. 12–13. Relying on the Microsoft Computer Dictionary, Patent Owner contends that “[a]n ‘operating system’ is, and would be understood by a person of ordinary skill in the art to be, ‘The software that controls the allocation and usage of hardware resources such as memory, central processing unit (CPU) time, disk space, and peripheral devices.’” PO Resp. 13 (citing Ex. 2007, 378). Dr. Brogioli’s testimony generally supports this construction, as does Dr. Horst’s. See Brogioli Dep. 8:17–22; Horst Dep. 32:3–8. Petitioner responds that the term “should be understood in accordance with its plain meaning,” and therefore does not require construction, but does not dispute Patent Owner’s proposed construction. Pet. Reply 2. For the reasons given, we adopt Patent Owner’s construction for “operating system.” However, we do not see this construction as dispositive of the central issue of whether the operating system in Sutardja controls the transition of the cores.

“PMS module do not ‘control’ the core switching module or the hardware on which it runs. Instead, the kernel and the PMS module only make system calls to the core switching module.” PO Resp. 27. We disagree that this is not sufficient control to meet this claim limitation. As Dr. Horst’s testimony (quoted supra) explains, the PMS module and kernel modules “trigger a transition” by generating a call to the hypervisor module or a core switching module. Horst Decl. ¶ 124. Patent Owner’s argument fails because it assumes the claims require direct control, when the claims recite no such restriction (nor have we been asked by either party to construe the claims as such).” slip op. at 28

“parties on the present record, we are persuaded Petitioner sufficiently shows the combination of Bosnyak-392 and Son teaches or suggests all of the limitations of claim 1, and sufficiently explains how a person of ordinary skill in the art would have used Bosnyak-392’s teaching of using exfoliated, open-ended carbon nanotube fibers having two different aspect ratios in a composition with improved electrical and mechanical properties, with Son’s implementation of a specific bimodal distribution of aspect ratios, to arrive at the composition of claim 1 with a reasonable expectation of success. We do not find persuasive Patent Owner’s arguments that Bosnyak- 392 teaches away from using nanotubes with a lower aspect ratio, or that Bosnyak-392 has an objective of maintaining longer nanotubes. See Prelim. Resp. 5–9. Patent Owner’s arguments appear to be based on a mischaracterization of Bosnyak-392, which read as a whole, discusses methods for exfoliating carbon nanotubes and physical properties of exfoliated nanotubes, such as length and diameter, that are not apparent when the nanotubes are aggregated. E.g., Ex. 1005 ¶ 37. Although Bosnyak-392 recognizes that nanotube exfoliating techniques tend to reduce nanotube length (see Ex. 1003 ¶ 28), it does not discourage the use of shorter nanotubes.
