      “and reliance on Figure 19 do not in any way explain how updating game costs by meter 502 with a new Cost_Table is relevant to a credit multiplier or even a multiplier being varied over time. Ex. 1003 ¶ 155. Considering this evidence, we determine that Petitioner and Mr. Crevelt’s reliance mainly on snippets from Schneier’s “Updating Cost Information protocol” embodiment does not sufficiently explain why or how a person of ordinary skill in the art would have understood updating game cost to encompass varying a multiplier of credits over time. We also note that during his deposition, Mr. Crevelt was given opportunity to clarify his testimony as to Figure 19 and explain the cost updating embodiment in Schneier, and mostly demurred. See Ex. 2004:158:4–182:6. Explaining his reliance on Figure 19, Mr. Crevelt stated: A: And whatever latest price from that updated cost information coming from the central site is -- is variable, it’s variable as time proceed[s].

See, e.g., id. at 160:16–23 (Mr. Crevelt testifying that “we can go from the description of figure 19, which starts at basically the top of column 56 in the Schneier patent, and . . . describes this process in detail of how the information is transferred from one place to the other and updated.”). Mr. Crevelt concludes that Schneier’s description is “complicated,” and from Figure 19 asserts the cost somehow includes a credit multiplier that “could” or “should” change over time. Id. at 158:23– 159:5. Overall, this testimony fails to sufficiently explain or point to persuasive evidence in Schneier as to how or why a person of ordinary skill in the art would have understood that the Figure 19 cost updating embodiment discloses a time-variable multiplier as required in claim 8.” slip op. at 20

      “Although the phrase “separate from,” is not found in the claims, we look to the language of the claims, the description in the patent disclosure, and the prosecution history to determine what type of separateness is required by the claims. We start with the relied-upon Figure 4 of the ’655 patent, which illustrates a box labeled “Multi-Scenario ECO Database 426” that is near, but not overlapping with or surrounding, boxes labeled “Image 424” through “Image 422” and “Image 420.” Ex. 1001, Fig. 4. The ’655 patent also describes a storage device 408 as “storing scenario images 420– 424 that correspond to different scenarios,” and “can additionally store multi-scenario ECO database 426,” which “can include circuit information for multiple scenarios that can be used to estimate the impact of ECOs in multiple scenarios.” Ex. 1001, 5:9–11, 5:18–21.” slip op. at 9

      “determin[e/ing . . . ] an ECO to fix one or more design requirement violations, wherein said determining includes identifying an ECO to fix a design requirement violation in the scenario and checking that ECO against at least some of the multiple scenarios by estimating parameter values based on parameter values stored in the scenario image and the multi-scenario ECO database. Resp. 10 (citing Ex. 2001, 21-24). In reviewing the term, the District Court explained that the multi- scenario ECO database “stores parameters and allows for a quick estimation of an ECO’s impact across multiple scenarios.” Ex. 2001, 19. The District Court further summarized the ’655 patent as describing that a scenario image is “[f]irst” loaded, and if there is a design requirement violation, an ECO is determined for that scenario, and then subsequent scenarios are loaded to check whether the ECO from the first scenario will create new, or exacerbate existing, design violations. Id. (citing Ex. 1001, 4:21–33). However, as recognized by the Court, the process at the cited section is described in the ’655 patent as an “approach [that] may take an impracticably long time to fix design requirement violations in multiple scenarios” due to the long time that is required to load a scenario image. Id. at 24; Ex. 1001, 4:43–47. The Court reasoned that in order to determine an ECO to fix a violation, “determine” must involve “identifying” a possible fix and “checking” whether that fix is suitable. Id. at 23. Thus, the District Court’s construction requires both identifying and checking as part of the claimed determining step. Id. at 23–24. We agree with the District Court’s reasoning, and apply their construction in this proceeding.” slip op. at 11

      “Petitioner assertion that Yoshimura’s estimation in step S5 is performed to check an identified ECO is supported by the record. In determining the change to be made (the ECO), Yoshimura uses estimated parameters for the third and fourth corner conditions, calculated in step S5 through the “Hold Margin” equation. Ex. 1007, 6:63–67. Those third and fourth corner conditions are then used to check potential layouts identified in step S6. Id. at 7:18–20 (“In step S6, the automatic EC device 16 searches for a layout that does not cause a timing error under any one of the first to fourth comer conditions from the analysis results of step S4 and step S5.”). In this manner, step S5 sets an initial third corner condition having estimated parameter values that is included, as the initial step, in checking an identified ECO at steps S6–S8. Thus, Yoshimura’s determination of a change to satisfy the corner conditions is, to use Dr. Edward’s phrase, “based on” its third and fourth corner conditions having parameters estimated in step S5. For this reason, we determine that Petitioner has sufficiently shown that Yoshimura discloses the claimed limitation.” slip op. at 20

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “2. Reason to combine Nicol and Bhatia Intel argues that a person of ordinary skill in the art “would have been motivated to combine the complementary teachings of Nicol and Bhatia” for the following four reasons: (1) both references “are directed to interrelated thermal and power management aspects that are critical and ubiquitous in processor-based systems,” Pet. 52–53 (citing Ex. 1008, code (54); Ex. 1009, 1:6–8; Ex. 1001 ¶¶ 231–233); (2) the references “both describe a flexible multiprocessor architecture in which software residing in a controller is programmed to selectively control the power supply of each processor, notably by dynamically adjusting the processor’s clock frequency during operation,” Pet. 53–54 (citing Ex. 1008, 2:18–27, 3:13–18; Ex. 1009, 1:57– 59, 2:28–31, 3:23–28, 3:33–38, 12:26–37; Ex. 1001 ¶¶ 231–233); (3) since Nicol “does not discuss over-temperature protection,” which is “critical for high-performance systems such as Nicol’s multiprocessor system,” a person of ordinary skill in the art “would have been motivated to consult Bhatia, which discusses well-known techniques of providing over-temperature protection,” Pet. 54–55 (citing Ex. 1008, 3:9–20, 4:11–13; Ex. 1009, 2:18– 22, 3:33–46; Ex. 1001 ¶¶ 231–233); and (4) a person of ordinary skill in the art “would have been motivated to consult Bhatia [to implement] low activity states in Nicol’s system as . . . means to further minimize power consumption,” Pet. 55 (citing Ex. 1009, 12:58–64; Ex. 1001 ¶¶ 231–233). In its Response, PACT argues that Intel’s four arguments “amount to little more than a suggestion that Nicol and Bhatia manage aspects of a computer system and it would be beneficial to combine these aspects,” which, “without any showing of actual motivation is plainly insufficient,” and “evidences application of impermissible hindsight bias.” PO Resp. 43– 44 (citing Ex. 2027 ¶ 110; Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1068 (Fed. Cir. 2018)). PACT also argues that Intel “makes no attempt to explain how a system combining Nicol and Bhatia would function, likely due to the fact that managing a plurality of metrics to create an efficient processing system is extremely difficult.” PO Resp. 44 (citing Ex. 2027 ¶ 111). Citing Dr. Mangione-Smith’s testimony, Patent Owner contends that a person of ordinary skill in the art “might spend their entire career developing intricate systems for managing processor temperature and clock frequency among a plurality of processors, and [Intel] dismisses it as a mere triviality.” Id. at 44–45 (citing Ex. 2027 ¶ 111).” slip op. at 58

      “The parties agree that a central monitoring device/service is a device/service that “watch[es], keep[s] track of, or check[s]” on something “from a central location.” See PO Resp. 21; Reply 2. On this record, we determine that the claim term central monitoring device/service is not further limited to a device/service that performs monitoring “during a monitoring session” such that it is able to “respond to patient status . . . when it detects evidence of certain physiologic conditions as they occur.” See PO Resp. 20– 22. The Specification uses the term “central monitoring device” in an openended manner, and Patent Owner does not identify any lexicographic definition or disclaimer that would limit this claim term in the manner it proposes. See PO Resp. 19–22; Tr. 38:1–17. The term “central monitoring service” does not appear in the Specification. Though Patent Owner cites a dictionary that defines “monitoring” as “constant checking on a patient’s condition” (Ex. 2021, 930), this definition is overly narrow because the Specification makes clear monitoring may be performed on a periodic basis. See, e.g., Ex. 1001, 3:6–35, 8:63–9:2. Moreover, Patent Owner’s other dictionary definition (Ex. 2020, 752) does not reference a patient, or require detecting “physiologic conditions as they occur.” Dr. Fernald’s testimony regarding this claim term (Ex. 2003 ¶¶ 39– 41) is not persuasive because the portions of the Specification he cites do not limit the term central monitoring device/service in the manner Patent Owner proposes (see Ex. 2003 ¶ 39 (citing Ex. 1001, 3:14–20, 6:42–47, 7:17–25, 7:57–64, 8:28–42); Tr. 38:1–17), and because Dr. Fernald does not adequately account for the dictionary evidence indicating that the claim term “monitoring” does not require constantly observing a patient’s status (see Ex. 2020, 752). We find persuasive Dr. Stone’s testimony that one of ordinary skill would have understood the portions of the Specification cited by Patent Owner and Dr. Fernald to be non-limiting examples. Ex. 1011 ¶¶ 21–34. For the foregoing reasons, on this record, and under the applicable broadest reasonable interpretation standard, we construe central monitoring device/service as a device or service “that watches, keeps track of, or checks from a central location.” 2.” slip op. at 9

      “On this record, and under the applicable broadest reasonable interpretation standard, we determine that the claim term “in communication with” encompasses indirect communications (e.g., communication by way of an intermediate component). We further determine that a processor need not generate a message, or respond to a message, in order to be “in communication with” a separate component. The ’403 Patent Specification uses the term “in communication with” in a broad, open-ended manner. See, e.g., Ex. 1001, 2:17–27, 2:42–48. In addition, Patent Owner does not cite any persuasive intrinsic or extrinsic evidence that a person of ordinary skill in the art would have read the claim term “in communication with” to exclude embodiments in which a processor merely receives information. See PO Resp. 40–44. Nor does Patent Owner cite any persuasive intrinsic or extrinsic evidence that the claim term “in communication with” excludes communication between a processor and a component when the processor is acting as an intermediary between that component and some other component.
