“the art would have combined the relevant teachings of Hildebrand and Van Ostrand with a reasonable expectation of success. As discussed above, Hildebrand is directed to a system for monitoring the efficiency of an HVAC system to determine when there is a fault. See Section II.E.1, supra; Ex. 1002 ¶ 60. Using much of the same data as Hildebrand, Van Ostrand teaches a method to determine which stage in a multiple stage HVAC system failed. See Section II.E.2; Ex. 1002 ¶¶ 60–61. Van Ostrand further teaches that the “[typical] HVAC system include[s] multiple stages of heating and/or cooling capacity.” Ex. 1007 ¶ 4. Because Hildebrand is silent as to which stage of the typical system—which has multiple stages— has failed, a person having ordinary skill in the art would have turned to Van Ostrand for that determination. Ex. 1002 ¶¶ 61–62. This modification would allow the Hildebrand system to detect which specific stage has failed. See Ex. 1007 ¶¶ 29–33. And because Van Ostrand represents a known method of detecting fault, it would have been obvious to use it to improve Hildebrand in a predictable way with a reasonable expectation of success. Ex. 1002 ¶ 63; see also KSR, 550 U.S. 398, 416–21. Petitioner has also sufficiently shown that a person having ordinary skill in the art would have added Rosen’s use of internet weather to the Hildebrand-Van Ostrand combination. See Ex. 1002 ¶ 115 (“Hildebrand and Van Ostrand are applied as I describe above with respect to Ground 1, with outside temperature over the Internet from a weather data provider. In my opinion, it would have been obvious to obtain outside temperature measurements from the Internet, thus replacing Hildebrand’s use of outside temperature sensors.”). Specifically, a person having ordinary skill in the art would have seen an advantage in avoiding the expense of obtaining, wiring and servicing an extra outside temperature sensor by obtaining weather information from the Internet as taught by Rosen. Ex. 1002 ¶ 120; see also Section II.F.1 (describing Rosen). Because it is undisputed that Rosen teaches using computer programming and network communications that were well-known and established at the relevant time period, there was a reasonable expectation of success. See Ex. 1002 ¶¶ 120–121.” slip op. at 35

“There is also no dispute that ym is the output from a computer model. See Pet. 69; PO Resp. 32. Again, that is consistent with Spalink, which defines item 310—which generates ym—as a reference model. Ex. 1008 Fig. 3; ¶ 75 (describing ym as the output of the refence model). Thus, there is no meaningful dispute that the comparison shown in Figure 3—which the Petition relies on—is a comparison between a first HVAC system and a model, not a second HVAC system as recited in claim 8. Accordingly, that comparison does not teach or suggest “compar[ing] the relative efficiency of the first HVAC system and the second HVAC system” as recited in claim 8. Petitioner’s arguments that the data in the reference model comes from other buildings is inapposite. Although Petitioner accurately describes how reference model 310 is based on “data 367 collected from different buildings” (Ex. 1008 ¶ 77), Petitioner has not shown that a computer model is a second HVAC system. Therefore, comparing the output of a building to a model based on buildings does not teach or suggest the necessary comparison between the first HVAC system and the second HVAC system recited in claim 8.” slip op. at 57

“b) Our Analysis We agree with Patent Owner that Petitioner has not sufficiently shown that Hildebrand teaches or suggests limitation [1c]. The gravamen of Petitioner’s argument is that Hildebrand’s HVAC system is limited to HVAC system 12—the heating system, cooling system, and fan. See Pet. 12 (“The HVAC system is ‘HVAC system 12’ . . . .”); Ex. 1004, 4:1–10 (describing HVAC system 12). Although nominally supported by Mr. Shah’s testimony, that testimony is conclusory, parrots the Petition, and provides no corroborating evidence to show that a person having ordinary skill in the art would have understood that an HVAC system was limited to the heating and cooling systems. We give Mr. Shah’s testimony on that point no weight. See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1368 (Fed. Cir. 2004) (“[T]he Board is entitled to weigh the declarations and conclude that the lack of factual corroboration warrants discounting the opinions expressed in the declarations.”); Verlander v. Garner, 348 F.3d 1359, 1371 (Fed. Cir. 2003) (Board has discretion to accord little weight to broad conclusory statements from expert witness); 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Moreover, Petitioner’s argument is inconsistent with Mr. Shahs’ direct testimony that clearly states that the HVAC system is broader then just the heating and cooling system and fan and includes other elements, such as thermostats and HVAC control systems. See Ex. 1002 ¶ 65 (“HVAC communications, and software, were widely known and understood.”). Applying Mr. Shah’s definition, the HVAC system as recited in claim 1 includes more than Hildebrand’s heating and cooling systems. Indeed, when discussing dependent claim 5, Petitioner argues that Hildebrand’s HVAC system also includes a thermostat. See Pet. 39. We do not find the Administrative Law Judge’s (“ALJ”) finding in an ITC proceeding involving a different record (and different patent) to be persuasive. Although the ALJ considered Hildebrand, there is nothing in the excerpt of the opinion to conclude that he considered Mr. Shah’s definition of an HVAC system. See Ex. 1010, 475–76. Nor is it clear from the record that the ALJ considered contrary testimony from Patent Owner’s expert. Id. Hildebrand Figure 1 shows an HVAC system including heating and” slip op. at 18

“We decline to find Dr. Palmer less credible based solely on his experience. In judging the credibility of experts, we focus on whether the witness offers corroboration for his opinions, provides opinions that are consistent with the prior art, and the witness’ cross-examination testimony. Moreover, we note that Mr. Shah and Dr. Palmer substantially parrot the Petition and Patent Owner Response, respectively. Such testimony is generally unhelpful.

Patent Owner does not appear to dispute this definition. See generally PO Resp; see also id. at 51 (employing Petitioner’s definition of a person of ordinary skill in the art in discussing Mr. Dunton’s testimony).

“We interpret the term “heartbeat signals” as “periodic signals.” The term “heartbeat” appears only once in the in the specification outside of the claims: “the ‘heartbeats’ of the ping are set at a high rate, such as 100 or even 1000 per second.” Ex. 1001, 18:7–13. The disclosure of “the heartbeats” having a “rate” defined in “per second” terms indicates that they are periodic, as is generally recognized for heartbeats, i.e. human heartbeats. The term “heartbeat signals” appears in the challenged claims in conjunction with the detection of an anomaly (claim 12, “wherein the controller detects an anomaly in heartbeat signals from the remote unit”) and in conjunction with “skips” (claim 13, “wherein the anomaly includes skips of heartbeat signals”; claim 14, “when the anomaly includes a predetermined number of skips of the heartbeat signals”; claim 15, “when skips of the heartbeat signals are less than the predetermined number”). Accordingly, the heartbeat signals allow for the detection of an anomaly therein, indicating that they are typically predictable, and for the detection of skips of heartbeat signals, indicating that they are periodic. In view of the specification and the claims, and the parties’ arguments, we find that the plain and ordinary meaning of “heartbeat signals” is “periodic signals.”” slip op. at 12

“Reply ignore the express statement in the Petition characterizing sensors 36 in Wedekind as “a source external to the building.” Sur-reply 2 (quoting Pet. 28), 3. Patent Owner also argues this is a new argument that we should disregard. Sur-Reply 2. We disagree. Although Patent Owner is correct that Petitioner contends Wedekind’s outside air temperature sensors 36 are a source external to the building, that is not the only argument Petitioner presents. In the Petition, Petitioner contends more generally that Wedekind’s outside air temperature sensors 36 “measure the outside air temperature.” Pet. 28. Petitioner also argues that Ehlers provides weather data including outside temperatures, and that the source of the data is a weather service provider that is external to the building. Pet. 32 (citing Ex. 1008, 9:53–54, 35:13–17). Petitioner further argues that it would have been obvious “to replace Wedekind’s outside temperature sensors 36 with receiving outside temperature data from a network connection,” as Ehlers teaches. Pet. 32. In view of this, we agree with, and are persuaded by, Petitioner’s argument that it does not rely only on Wedekind to meet the limitation that “the second data from the network connection is collected from a source external to the building.” Reply 10. Additionally, the presence of these arguments in the Petition undermines Patent Owner’s assertion that Petitioner is attempting to present new arguments in the Reply. Similarly, Petitioner acknowledges in the Petition that Wedekind does not expressly teach the second data is received from a network connection, and, therefore, relies on Ehlers’ disclosure of receiving data from a network connection. Pet. 30; Reply 11. Patent Owner does not dispute that Ehlers discloses receiving weather data from a network connection. See PO Resp. 15–28; Sur-reply 3–8. In view of the foregoing, Petitioner has demonstrated persuasively that the combined disclosures of Wedekind and Ehlers teach or suggest “the one or more processors further configured to receive a second data from a network connection, wherein the second data from the network connection is collected from a source external to the building” claim 1 requires.” slip op. at 20

“We find Petitioner’s arguments to be persuasive. Petitioner presents undisputed evidence, based on the disclosure of Wedekind and Ehlers, that obtaining outside temperatures either from local sensors or over a network was known in the art. Pet. 28–32; Ex. 1006, 4:45–47; Ex. 1008, 9:50–63. Petitioner also directs us to evidence, including in Ehlers itself, supporting Petitioner’s reasoning that replacing Wedekind’s outside air temperature sensors with a network-based weather data service would have saved the cost and effort of installing multiple sensors. Pet. 32; Ex. 1002 ¶ 103; Ex. 1008, 39:54–57; Reply 13. As Petitioner points out, Patent Owner does not directly challenge Petitioner’s argument and evidence that a person of ordinary skill in the art would have had reason to modify Wedekind in view of Ehlers to avoid the cost and effort of installing multiple sensors. Reply 13.5 Indeed, Patent Owner acknowledges that Wedekind “expressly indicates that there must be multiple sensors of outdoor temperature for sufficient accuracy in Wedekind’s complex computational model.” PO Resp. 26; Ex. 1006, 3:62–67. The need for multiple sensors in Wedekind 5 We recognize Patent Owner argues that a person of ordinary skill in the art would not have been motivated to connect Wedekind’s outside air temperature sensors 36 to a network because it would “increase costs.” PO Resp. 23–24. Patent Owner, however, presents this argument before it addresses Petitioner’s proposed combination of Wedekind and Ehlers. See PO Resp. 23–24 (referring to cost increases first, and addressing the proposed combination of Wedekind and Ehlers in the next paragraph). Thus, Patent Owner’s cost argument does not appear to address Petitioner’s assertion regarding cost savings in view of the proposed combination. Nor does Patent Owner present evidence regarding, or explain adequately, what costs it is referring to, or how those costs would increase. PO Resp. 23–24; Ex. 2005 ¶ 61. By way of contrast, Petitioner’s arguments regarding cost savings are supported by the disclosure of Ehlers itself. Ex. 1008, 39:54–57. strengthens Petitioner’s argument that a person of ordinary skill in the art, in view of Ehlers’ teaching regarding avoiding the cost and effort of installing multiple sensors, would have had reason to modify Wedekind in view of Ehlers. Additionally, Patent Owner’s own declarant characterized Ehlers’ discussion of “lowering the cost of installation and ongoing maintenance” as “teach[ing] away from external sensors.” Ex. 1023, 58:7–18. These arguments and evidence undermine Patent Owner’s assertion that Petitioner failed to provide any analysis as to why a person of ordinary skill in the art would have modified Wedekind in view of Ehlers. Sur-reply 3–4; PO Resp. 25–28. Petitioner also argues, and provides evidence in the form of testimony from Dr. Shah demonstrating, that a person of ordinary skill in the art would have been able to modify Wedekind’s system by connecting Wedekind’s processing means to a network connection such as Ehlers’ phone input or communications link, and would have obtained predictable results. Pet. 33; Ex. 1002 ¶ 104. Patent Owner does not dispute this evidence. To the contrary, Patent Owner appears to concede that the proposed combination would work, although not as reliably as Wedekind’s hardwired system. PO Resp. 25–26. As a result, and in the absence of any evidence or argument suggesting otherwise, we credit Dr. Shah’s testimony. Furthermore, Ehlers teaches, in connection with providing data obtained from a weather service provider over a network, that “[t]he data may be provided at regular intervals and be sufficiently localized for acceptable accuracy.” Ex. 1008, 9:58–60. This statement from Ehlers itself undermines Patent Owner’s arguments regarding alleged problems with transmitting data over networks and insufficient accuracy, including Patent Owner’s argument that Wedekind teaches away from the approach used by Ehlers. PO Resp. 25–28. Nevertheless, even if we were to give Patent Owner the full credit of its arguments regarding unreliable transmission of data over networks and data obtained from weather service providers being less useful than data obtained from sensors at a specific structure, obviousness “does not require that the motivation be the best option, only that it be a suitable option from which the prior art did not teach away.” PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1197-98 (Fed. Cir. 2014). As discussed above, Petitioner’s evidence and arguments demonstrate that using Ehlers’ network to transmit temperature data was at least a suitable option. For all of the foregoing reasons, we determine Petitioner has demonstrated persuasively that a person of ordinary skill in the art would have had reason to modify Wedekind in view of Ehlers, and would have had a reasonable expectation of success in doing so. iii.” slip op. at 25
