      “IPR2024-00783, Ex. 1001, 22:36–49. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112 ¶ 6. See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112 ¶ 6 is not overcome.” slip op. at 17

      “differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, “would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of non-obviousness.

      “We find persuasive Dr. Wolfe’s supporting testimony that a POSITA would have understood the terms “PDK” and “RDC” to have “definite structure.” Ex. 1013 ¶¶ 35–56. In particular, we find persuasive Dr. Wolfe’s testimony that the term “PDK,” for example, “encompasses at least ‘a collection of circuit components that includes an antenna, a transceiver, and a controller and memory for storing information particular to a user.’” Id. ¶ 35. Dr. Wolfe’s testimony is consistent with the Specification of the ’188 patent. See Ex. 1001, 5:42–6:7, 3:48–62. In particular, the Specification of the ’188 patent describes a microchip that stores information in memory and responds through an antenna when probed, which is consistent with Dr. Wolfe’s testimony.

      “¶ 39). Petitioner further relies on Stokes to teach an average particle size that preferentially scatter blue . . . LED light as compared to yellow . . . light from the luminescent material.” Id. at 26–27 (citing Ex. 1108, 7:1–4). Petitioner argues that “a POSA would have been motivated to apply this principle to Krummacher, because it would increase the conversion of blue light to yellow light and improve the uniformity of the light source.” Id. at 27 (citing Ex. 1102 ¶ 237). Petitioner notes that “[c]onversion of blue light to yellow light is improved by maximizing the scattering of blue light.” Id. In addition, Petitioner asserts that “[u]niformity is improved by preferentially scattering the concentrated light from the blue-light LED chip instead of the disperse light emitted by the phosphor.” Id. at 28 (citing Ex. 1102 ¶ 237). Petitioner contends that “[a] POSA would have had a reasonable expectation of success applying this principle to Krummacher, because the relevant particle size range includes the range disclosed by Krummacher.” Id. Petitioner argues that “[a] POSA would have recognized selecting an average particle size as a design decision to be made based on a number of factors, including the light scattering properties of the particles, and well within the skill of the art.” Id. (citing Ex. 1102 ¶ 238). We find this explanation and the supporting testimony of Dr. Doolittle well-reasoned and supported and entitled to significant weight.

      “Finally, we do not agree with Patent Owner that “quantum efficiency” would have dissuaded a person of ordinary skill from making the combination. PO Resp. 36–38. To begin with, “[i]t’s not necessary to show that a combination is the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021). Here, as demonstrated by, at least, Shimizu and Stokes, blue LEDs in this wavelength range were known to work as light sources for white-light LEDs. See Pet. 30–31. Additionally, we find persuasive Petitioner’s evidence that a person of ordinary skill in the art would not have been concerned solely with quantum efficiency, but also with overall luminous efficacy of a complete white LED package. Reply 9. As Dr. Schubert’s textbook explains, A fundamental drawback of UV pumped white LEDs is the energy loss (Stoke’s shift). The potential luminous efficacy of UV pumped white LED lamps is, therefore, markedly lower than that of white sources based on a blue LED exciting a yellow phosphor. Ex. 2014, 358–59; see also Ex. 1148, 87:5–88:4 (acknowledging Stokes shift). Thus, the evidence shows that, whatever gain in quantum efficiency a lower wavelength might offer, there were other drawbacks that a person of ordinary skill would have to balance. But “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.” Medichem, 437 F.3d at 1165. Indeed, Petitioner has shown several references—including, Shimizu and Stokes—that made this tradeoff. Moreover, “[o]bviousness does not require absolute predictability of success. . . . [A]ll that is required is a reasonable expectation of success.” In re O’Farrell, 853 F.2d 894, 903–04 (Fed. Cir. 1988). We find that the prior art of record demonstrates that a person of ordinary skill in the art at the time of the invention would have such an expectation in making the combination of Krummacher, Stokes, and Shimizu. Accordingly, we find that Petitioner has shown by a preponderance of the evidence that there would have been motivation to combine Krummacher, Stokes, and Shimizu with a reasonable expectation of success.” slip op. at 43

      “C. Claim Construction We construe claims “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” 37 C.F.R. § 42.100(b); see also Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). In this context, claim terms “are generally given their ordinary and customary meaning” as understood by a person of ordinary skill in the art in question at the time of the invention. Phillips, 415 F.3d at 1312–13; see CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366 (Fed. Cir. 2002) (There is “a ‘heavy presumption’ that a claim term carries its ordinary and customary meaning.”). “In determining the meaning of the disputed claim limitation, we look principally to the intrinsic evidence of record, examining the claim language itself, the written description, and the prosecution history, if in evidence.” DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 469 F.3d 1005, 1014 (Fed. Cir. 2006) (citing Phillips, 415 F.3d at 1312–17). Extrinsic evidence is “less significant than the intrinsic record in determining ‘the legally operative meaning of claim language.’” Phillips, 415 F.3d at 1317. Petitioner contends that “[t]he claim terms of the ’218 [patent] should be given their plain and ordinary meaning” as understood by the relevant artisan. Pet. 6. Petitioner argues that the relevant artisan “would have understood a ‘socket’ to be a uniquely addressable communication endpoint on a server where first event information is provided to a [viewer client device] VCD.” Pet. 26 (citing Ex. 1001 ¶ 170). Petitioner argues that the relevant artisan also would have understood an “event socket,” in turn, to be “a socket where information about one sporting event is provided to VCDs.” Id.

Based on the context discussed above, and for the reasons provided above, we determine that the answer is yes. See Fleming v. Cirrus Design Corp., 28 F.4th 1214, 1222 (Fed.

Although Patent Owner argues that “it was filed to conserve the limited resources of the Board and the Parties in light of the fact that the ’290 Patent is no longer involved in any copending litigation” (Ex. 3001), we deem such argument not a persuasive reason as to why we should not apply § 42.73(b)(2), or why termination is more appropriate. Pursuant to 37 C.F.R. § 42.73(b)(2), we construe Patent Owner’s disclaimer of all claims at trial as a request for adverse judgment, which we grant.” slip op. at 3

      “1. “dynamic attribute of an electric charge provider” In the Petition, Tesla proposes that we construe “dynamic attribute of an electric charge provider,” as recited in every independent claim, to mean “a changing or otherwise fluctuating cost (or price) of electricity for purchase from an electric charge provider.” Pet. 4–5. Charge Fusion responds that Tesla improperly narrows the meaning of this claim limitation. PO Resp. 15 (arguing this claim term “is not just limited to ‘changing or otherwise fluctuating cost (or price)’ as alleged by the Petition” (emphasis added)). Although we consider Tesla’s proposed construction to identify an exemplary “dynamic attribute of an electric charge provider,” we see no need to limit the meaning of this limitation as proposed by Tesla. Indeed, Tesla agrees. See Pet. Reply. 7 (arguing only that this claim limitation “at least includes” such an example). And Charge Fusion does not contend otherwise. See PO Resp 15 (arguing only that this limitation “is not just limited to” cost fluctuations). As such, we see no need to further construe this claim limitation. 2. “determine . . . a charging schedule for the vehicle” Limitation 1[g] recites “determine, based at least on the one or more charging preferences and at least one current value of a dynamic attribute of an electric charge provider, a charging schedule for the vehicle.” Independent claim 8, 15, and 22 recite a materially identical limitation. Tesla submits that this limitation should not be construed as a means-plus- function limitation under 35 U.S.C. § 112(6). See Pet. 5.

      “Initially, we note that, as claimed, there is no express restriction on the manner in which the “amount” or “charge” is specified or otherwise expressed. Indeed, the Specification uses both “desired charge percent level” and “desired charge range level” as alternative ways for a user to specify an “amount of charge.” Ex. 1001, 14:53–15:8 (emphases added). The Specification defines “desired charge range level” as meaning “a desired distance to travel.” Id. at 15:3–8. Elsewhere, the Specification describes that a user may specify the amount of charge as follows: “the user may indicate a desired charging level (and/or a desired charging level may be automatically calculated) based on a desired distance of travel.” Id. at 19:49–57 (emphasis added). More specifically, annotated Figure 7 of the ’987 patent, reproduced below, demonstrates how a user may select “amount of charge” in terms of a desired mileage range 720 or a percentage level 718. See Pet. Reply 2. As shown in red, annotated Figure 7 illustrates that a user selects “desired charge level 720” on “vehicle charge indicator 714” by moving a slider to a value specified in “miles” (e.g., 110 miles). The Specification, after discussing selecting a desired charge percent level 718, explains: The user may also or alternatively view and/or change the desired charge range level 720. An estimate of how far the vehicle can travel on a given charge amount (which may be a general average and/or may be computed based on a specific itinerary and/or past driving habits) can be determined, for example, and utilized to express the desired charge level in terms of distance capable of being traveled. In such a manner, for example, a user may determine a desired distance to travel (e.g., how far it is from home to work or vice versa) and may set the desired charge range level 720 to match the desired distance. Ex. 1001, 14:65–15:8. Thus, the Specification confirms that “amount of charge” may be expressed in terms of a desired mileage as well as a desired percentage level.” slip op. at 11

      “We disagree. Charge Fusion’s reliance on Wonderland is misplaced and does not support the proposition for which it is cited. In Wonderland, the district court denied the accused infringer’s motion for summary judgment of invalidity, in part, because genuine issues of material fact existed as to whether there was sufficient motivation to combine the prior art. Wonderland, 988 F. Supp. 2d at 511. As such, the district court’s Wonderland decision does not constitute a final ruling on the motivation to combine issue, and the Federal Circuit’s summary affirmance of the district court’s ruling neither addresses the issue nor reflects how the issue was resolved at trial. See Wonderland NurseryGoods Co. v. Thorley Indus., LLC, 644 F. App’x 1011 (Fed. Cir. 2016). Moreover, contrary to Charge Fusion’s assertion, Tesla correctly notes that although Ferro refers to wireless charging, it provides no implementation details. Ex. 1004 ¶ 36; Ex. 2006, 54:8–55:9. Nonetheless, Ferro does describe manual options for initiating charging, and Tesla’s expert credibly testifies that one of ordinary skill in the art would have been motivated to apply Oyobe’s vehicle sensor to allow a user to initiate Ferro’s charging methods more easily without having to leave the vehicle. See Ex. 1003 ¶¶ 146, 151, 152 (citing Ex. 1004 ¶ 109). Accordingly, we find that Tesla establishes that one of ordinary skill in the art would have been motivated to incorporate Oyobe’s use of a sensor to establish presence of a vehicle near a charging station into Ferro’s system.” slip op. at 17

Charge Fusion responds that Tesla’s proposed construction should be rejected because it “wrongly import[s] embodiments from the specification.” PO Resp. 14–16. We discern no dispute over the meaning of “unitary vehicle charge indicator” because, contrary to what Charge Fusion argues, Tesla does not contend that this limitation is “required to be limited to” the bar graph embodiment of Figure 7, only that it “at least includes” that embodiment. Compare Pet. 5, with PO Resp. 14–16. Tesla also argues that the “first” and “second” portions of the unitary vehicle charge indicator—which indicate the charged and uncharged capacities of the battery—recite merely “communicative content,” and thus, are “not entitled to any patentable weight” because they are directed to nonfunctional printed matter.

      “full charge” for the battery, and thus, Tesla fails to explain how the combination of Sutardja with Donnelly’s battery bar graph image “would allow a user to select a specific amount of charge or how this would result in a unitary vehicle charge indicator,” as claimed. PO Resp. 30. According to Charge Fusion, “[l]imiting the single option of ‘full charge’ as described in Sutardja would defeat the purpose of implementing a slider” as taught by Donnelly. Id. (citing Ex. 2008 ¶ 72). We disagree. Charge Fusion’s argument rests on the mistaken premise that Sutardja only contemplates selecting a full amount of charge for the battery and not an amount below a full charge, i.e., a partial charge. But that is not what Sutardja says. More accurately, Sutardja teaches that the user specifies the amount of charge—"The user interface module 108 may comprise a key pad, a display, a microphone, and/or a speaker (all not shown). A user of the vehicle 102-1 may use the user interface module 108 to set charging parameters for charging the battery 14.” Ex. 1011 ¶ 243. Elsewhere, Sutardja teaches that the user may set a “predetermined level” of charge— The charge monitoring module 150 may inform the control module 112 when the battery 14 is charged to a predetermined level (e.g., full charge) that may be indicated in the charging parameters. Subsequently, the charge monitoring module 150 may stop charging the battery 14 by deactivating the converter 156 and the charging module 152. The power meter 24 may measure the amount of power received from the utility company 23 during the charging operation. Id. ¶ 270 (emphases added). Although that passage indicates that a “full charge” is an example of a “predetermined level” of charge, nowhere does it exclude the selection of a lesser amount. Indeed, the passage contemplates the ability to “stop charging the battery,” which indicates that selection of the predetermined level may be less than a full charge. Id. Thus, we are not persuaded by Charge Fusion’s argument to the contrary. Rather, in our view, Tesla demonstrates by a preponderance of the evidence that the Sutardja-Donnelly combination teaches a “unitary vehicle charge indicator” that includes at least “first” and “second” portions and that one of ordinary skill in the art would have had reason to successfully combine their respective teachings in a manner that allows a user to predetermine, i.e., specify, an amount of charge. slip op. at 17

      “We find Petitioner’s contentions with Dr. Wicker’s supporting testimony persuasive. In particular, we find Petitioner’s reliance on Spivey for disclosing “event socket” is supported by Spivey’s disclosures that a topic queue’s address “may resemble a uniform resource locator (URL)” and that user interface 900 “allow[s] an operator 108 of a client device to view and select . . . topics available from a message queue server.” Ex. 1017 ¶¶ 82, 84, Fig. 9. In Spivey, the message flow begins “when message queue server . . . pushes data payloads to subscribers of the topics in [the] message.” See Ex. 1017 ¶ 134.

Reply 8 (citing Ex. 1001 ¶¶ 353–354). We find availing that, in Spivey, since the “client devices ‘request a live data connection’ by selecting or entering the address or connection information which ‘may resemble a uniform resource locator (URL),’” Spivey’s topic queues “are not only logically but also actually implemented as uniquely addressable communication endpoints.” Id. at 9 (citing Ex. 1064 ¶¶ 11–14). We find that Dr. Rubin’s testimony that the only potential “communication endpoint” in Spivey that is “uniquely addressable” is the live data access server (Ex. 2001 ¶ 233) merely addresses particular embodiments in Spivey.

      “As Petitioner explained during Oral Argument, Ellis “relates to the ability for the clients and the server to communicate,” which can be any system that can “provide real-time sports,” but “doesn’t discuss whether it’s a push system or a pull system,” whereas Spivey, on the other hand, “expressly indicates that it is a push type of data system which reduces latency over prior art systems that utilize push technologies.” Tr. 15:13–19. We find availing Petitioner’s contention that, “[a]s explained by Dr. Wicker, . . . [the relevant artisan] would have been motivated to implement real-time data delivery using Spivey’s data pushing technique to reduce latency.” Id. at 16:2–8. “[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 improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. We find unavailing Patent Owner’s contention that Petitioner fails to “articulate why [the relevant artisan] would have been motivated to make the necessary modifications and proposed combination.” PO Resp. 40–41. Here, Petitioner points out that its proposed combination would have been made to improve latency issues in Ellis’s system. Pet. 20–22. In particular, Spivey discloses that its techniques “may reduce . . . delay [on the order of seconds (e.g., 30 to 45 seconds) or minutes] to an order of milliseconds (ms) (e.g., 100 ms) or less, providing a significant advantage over the conventional practices.” Ex. 1017 ¶ 28. Spivey also discloses pushing data to the “subscribed connected client devices” substantially simultaneously with the message queue server receiving the topic entry from a live data source, e.g., “with a time delay of 100 milliseconds or less,” which Spivey discloses is “at least two orders of magnitude shorter than conventional time periods of legacy devices.” Id. ¶ 96; see also id. at code (57) (disclosing pushing “the topic entry to a subscribed client device substantially simultaneously with the message queue server receiving the topic entry from a live data source”). We find Patent Owner’s arguments that Petitioner fails to “explain the modifications necessary to combine such teachings” are inconsistent with the evidence of record. PO Resp. 40–47. For example, Patent Owner’s argument that the proposed combination would be inoperable because the combination “does not include the LDAS” (id. at 43–44) is not consistent with the evidence of record that Spivey does not require the LDAS to serve as intermediary between the MQSD and the user equipment. See Ex. 1017 ¶¶ 38, 46. As discussed above, Spivey states that the system “may” include an LDAS (Ex. 1017 ¶ 38), supporting Petitioner’s contention that, in Spivey, the LDAS is “optional” wherein “the MQSD may be ‘accessible to clients over the network directly.’” Pet. Reply 3. As discussed above in Section III.D.3.a, we find persuasive Petitioner’s argument that Spivey’s MQSD may push data from topic queues to the subscribers of the topics corresponding to those topic queues, which indicates that “the MQSD can deliver data directly to clients without the necessity of an LDAS.” Id. (citing Ex. 1017 ¶ 46).” slip op. at 39
