RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“Here, Petitioner asserts a person of ordinary skill in the art would have “had at least a four-year undergraduate degree in electrical engineering, automotive engineering, or a closely related field and at least two years of experience in the field of access control systems, vehicle electronics, and/or cryptography.” Pet. 8–9 (citing Ex. 1004 ¶ 85). Dr. Almeroth supports Petitioner’s position and further testifies that “[a]dditional education could substitute for professional experience and vice versa.” Ex. 1004 ¶ 85. Patent Owner does not assert a different level of skill in the art at the time of the alleged invention and appears to apply Petitioner’s proposed level of skill. See PO Resp. Patent Owner’s declarant, Dr. Malek, explicitly adopts Dr. Almeroth’s level of skill in the art but states that his opinions would be applicable under any reasonable definition for an ordinarily skilled artisan at the critical time. See Ex. 2021 ¶ 38. For the purposes of this Decision, we too adopt Petitioner’s level of ordinary skill in the art because it appears consistent with the problems addressed in the ’659 patent and the prior art of record.” slip op. at 12

“We do not agree with Patent Owner’s argument that Dr. Almeroth’s declaration testimony contradicts Kleve. See PO Resp. 27–29. Rather, as discussed previously, we find that Kleve’s vehicle owner can set a restriction, such as the rental start period, prior to step 214 in Kleve’s Figure 2 and that such restrictions can be associated with the e-key. We also do not agree with Patent Owner’s argument that (1) Dr. Almeroth’s declaration testimony contradicts his deposition testimony or that (2) Dr. Almeroth “admitted his testimony was wrong.” See PO Sur-Reply 7 (citing PO Resp. 47–48 (citing Ex. 2022, 27:5–10, 27:21–28:1; Ex. 2021 ¶ 96)). In a particular embodiment to which Dr. Almeroth was citing, he noted that the e-key is always generated after the rental agreement. See Ex. 2022, 26:14– 20. Then the following exchange occurs: Q. So you use typically and always. So always does not refer to all of the embodiments of Kleve, is that fair? A. I think a person of skill in the art could read Kleve and understand that there are probably multiple ways in which the flow of actions among the parties could occur. And I think thinking about a real world scenario, in most cases you have an agreement before you would generate an eKey, but maybe, maybe not. I don’t -- I don’t know that the real world is necessarily cut and dry. So reading -- a person reading Kleve would understand it’s describing embodiments where it’s scenario, but I don’t know that it would necessarily be a hard and fast rule in every embodiment or in the understanding a person of skill in the art would have. Id. at 28:3–20. There is nothing in the deposition testimony by Dr. Almeroth that appears inconsistent with his declaration testimony nor does there appear to be the kind of admission touted by Patent Owner. Instead, it is Dr. Malek who takes an overly narrow view of Kleve that appears inconsistent with Kleve’s disclosure when read as a whole. See, e.g., Ex. 2021 ¶¶ 82–88. Therefore, we do not credit or agree with Dr. Malek’s testimony that Kleve fails to teach the concept of a virtual key created with the agreed-upon rental period as a restriction. See id. ¶ 57. Thus, based on the entire trial record, we find that Petitioner has” slip op. at 33

“After review of the arguments and evidence, we agree with Petitioner’s position. Specifically, we agree that (1) both Kleve and Hatton are directed to use of electronic key systems for vehicles (see Ex. 1005 ¶¶ 7– 9, 39, 63; Ex. 1008, 1:48–52, 1:61–2:2, 5:25–34) and (2) encrypted communications would have been understood to be effective in preventing unauthorized access to the vehicle, something that is taught explicitly by Hatton (see Ex. 1008, 9:50–63). Given these disclosures by Kleve and Hatton, we find that a person of ordinary skill in the art would have had a at the challenged claims. Accordingly, we find that a person of ordinary skill in the art at the critical time would have had a reason to combine the teachings of Kleve with that of Hatton.” slip op. at 36
- Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightNot shown unpatentableNot shown unpatentable
“We agree with Patent Owner. Petitioner’s argument appears to be purely hindsight analysis based on the teachings of the ’659 patent and the limitations of challenged claim 6 because there is insufficient evidence or teachings in the cited prior art to suggest the sharing of virtual keys. Petitioner’s argument that having “rental microbusiness” implemented as a “smart phone application” that enables sharing virtual keys is insufficient to show obviousness, because, as noted by Patent Owner, certain embodiments in Kleve appear to discourage or even hinder the sharing of virtual keys. These embodiments require the use of credentials associated with the virtual key, where the credentials can be “facial recognition, voice print recognition, matrix barcode (ex. two-dimensional code), code word or phrase for speech recognition, temporary mobile web login IDs and password, or other types service.” See Ex. 1005 ¶ 37. Dr. Almeroth testifies that multiple people could be authorized on the same vehicle if they collectively rent a vehicle and that a person of ordinary skill in the art would “have been motivated to enable each user to share the virtual key with other authorized users associated with the same rental request.” Ex. 1004 ¶ 55. But given Kleve’s disclosure that the system handles key generation and distribution (Ex. 1005 ¶ 39), the evidence does not show that a person of ordinary skill in the art would have wanted to give this control to each authorized user who has received an e-key. “It is impermissible to use the claimed invention as an instruction manual or ‘template’ to piece together the teachings of the prior art so that the claimed invention is rendered obvious.” Fritch, 972 F.2d 1260, 1266 (Fed. Cir. 1992) (citing In re Gorman, 933 F.2d 982, 987 (Fed. Cir. 1991)). Kleve’s teachings undermine Petitioner’s position, and do not support a finding of obviousness. Accordingly, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Kleve alone or in combination with Hatton would have rendered dependent claim 6 obvious to a person of ordinary skill in the art at the critical time.” slip op. at 39

“In our Institution Decision in IPR2024-01357, we analyzed claim 1 of the ’678 patent in light of Basin-2007 and Basin-2005. ’1357 IPR, Paper 17, 23–28. We concluded, after reviewing the arguments presented there, that “Petitioner has demonstrated a reasonable likelihood of proving that the combined teachings of Basin-2005 and Basin-2007 render claim 1 unpatentable as obvious.” Id. at 28. In this proceeding, Petitioner has presented a challenge to claim 1 based on those same references that it represents is a “verbatim” copy of its previous challenge to claim 1 in the ’1357 IPR. Pet. 1–2, 28–35. Petitioner supports its challenge with expert testimony. Ex. 1002 ¶¶ 107–125.7 Patent Owner has not submitted a response on the merits of this challenge. For the purposes of this Decision, and for the reasons given in the Petition, we adopt the analysis in our Institution Decision in the ’1357 IPR (at pp. 23–28), where we determined that Petitioner has demonstrated a reasonable likelihood of prevailing on its obviousness challenge to claim 1 based on Basin-2005 and Basin-2007. Turning now to Petitioner’s challenge to claim 11, Petitioner relies on Basin-2007 and Stokes for the particle size limitations added to claim 1 by that dependent claim. Pet. 35–39. Thus, Petitioner asserts that “Basin-2007 discloses a light scattering material with an average TiO2 particle size that is ‘sub-micron’ (less than 1000 nm).” Id. at 37 (citing Ex. 1005 ¶ 5). 7 Exhibit 1002 appears to be a duplicate copy of Dr. Doolittle’s declaration from the ’1357 IPR. Petitioner concludes, “Basin-2007 renders obvious claim 11 by literally disclosing the selection of average particle sizes that preferentially scatter blue light.” Id. Further, “to the extent that the claim language ‘an average particle size that is selected such that [it preferentially scatters blue light]’ requires an average particle size selected for that reason (rather than an average particle size that leads to that outcome), this claim element is rendered obvious by Stokes.” Id. at 38 (citing Doolittle Decl. ¶ 45) (alterations in original). Petitioner explains that “Stokes explicitly discloses the selection of an average particle size ‘such that the particles preferentially scatter blue . . . LED light as compared to yellow . . . light from the luminescent material.’” Id. at 38 (citing Ex. 1008, 7:1–4) (alterations in original). Petitioner provides a motivation for combining Stokes with Basin- 2007 with a reasonable expectation of success. Pet. 38–39. Petitioner explains that “[t]o the extent that claim 11 is understood to also claim the basis for selecting a particular average particle size, a [person of ordinary skill] would have had reason to use such a basis for selecting average particle size as taught by Stokes.” Id. at 38 (citing Doolittle Decl. ¶¶ 46–48). Further, “a [person of ordinary skill] would have been motivated to apply this principle to Basin-2007, because it would increase the conversion of blue light to yellow light and improve the uniformity of the light source.” Id. at 39 (citing Doolittle Decl. ¶ 48).

“See Section II.C.3.a.ii supra.

Hayhurst also discusses piracy deterrence in both the Summary of the Invention section (id. ¶ 8) and the invention’s detailed description (id. ¶ 21).

The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date.

“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

“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. For the reasons given, we do not see the need to modify our definition of a person of ordinary skill or to exclude or give little weight to Dr. Horst’s opinions.” slip op. at 15

“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
