Patent Owner contends that the plain and ordinary meaning of “feed” is “one or more associated media elements.” See, e.g., PO Resp. 4. However, as discussed below, this alleged plain and ordinary meaning of feed is not supported by the claim language, the specification of the ’753 patent, or dictionary definitions of feed as contended by Patent Owner. We reject this contention and the related contentions that the cited art may be distinguished from the claims of the ’753 patent based on the recited term “feed.” Patent Owner relies on the language of claim 1 to support its” slip op. at 13

    “The parties’ definitions are similar, although we observe that Patent Owner proposes that the person of ordinary skill would have a bachelor’s degree or an equivalent or professional experience, whereas Petitioner proposes that such a person would have both a degree and experience. Neither party presents any arguments relating or referring to the level of ordinary skill in the art. Determining the level of ordinary skill in the art involves various factors, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citation omitted). The prior art of record also reflects the level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We adopt Petitioner’s assessment of the level of skill in the art. Petitioner’s assessment is supported by the testimony of Dr. Almeroth and is consistent with the ’753 patent and the asserted prior art. However, our obviousness analysis would be the same under either party’s assessment. See Ex. 2014 ¶ 17 (Patent Owner’s declarant, Dr. Goodrich, stating that “I note that my definition of a POSITA is similar to that of Dr. Almeroth” and “My opinions in this declaration would not change were I to adopt the definition of a POSITA offered by Dr. Almeroth.”).” slip op. at 11

Petitioner supports this contention by articulating the following reasons for the asserted modification of Whitehead’s mixing server 130 to incorporate Marcus ’904’s algorithm: “makes it more likely the system will identify content best suited for a particular user,” “allows for more targeted advertising and/or an opportunity to maximize revenue,” “improves Whitehead’s ability to target content and advertising to a particular user,” “would unlock new revenue sources for Whitehead,” “Marcus ’904’s content selection and concatenation algorithm improves Whitehead’s efficiency,” “[b]oth Whitehead and Marcus ’904 generate custom media programming based on a user profile,” “incorporating Marcus ’904’s teachings would not require redesigning Whitehead’s architecture and instead merely supplements Whitehead’s disclosure,” and “Petitioner’s proposed modification can be implemented entirely in software and does not require any hardware modifications. Indeed, Whitehead acknowledges that such modifications are possible. EX1003 at 19:64-20:6, 22:26-40.” Id. at 33–35 (citing Ex. 1002 (Almeroth Decl.) ¶¶ 110–115) (emphasis omitted).

  • Skill levelSkill level board ownDecided for petitioner

    “Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” is too narrow. Although Patent Owner points to various parts of the ’518 patent as supporting its restrictive proposal, other parts of the patent are not so limited. For example, the patent’s technical field and summary are not limited to coaxial cable, and the patent discusses twisted pair wiring and satellite communications as media that can be used. See, e.g., Ex. 1001, 1:27–29, 3:33–35, 3:49–50, 3:67–4:3, 5:61–6:3, 8:20–23, 9:28–33. Accordingly, we adopt the following level of ordinary skill in the art for use in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to four years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find that this skill level is consistent with the problems and solutions identified in the ’518 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

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

    “Although Patent Owner argues that adding Konstaninos’s multi- channel functionality to Kamieniecki’s single-channel device would increase costs and complexity, Patent Owner overlooks that multi-channel functionality would also increase the STB’s capabilities. In any case, “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate a motivation to combine.” General Elec. Co. v. Raytheon Tech. Corp., 983 F.3d 1334, 1351 (Fed. Cir. 2020) (citing Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006)). Furthermore, Petitioner presents preponderant evidence that the market demand was such that customers would have desired an STB with multi-channel functionality even though it would cost more than a basic STB. Pet. Reply 6–8 (citing Ex. 1010 ¶¶ 1, 11, 16, 102–104; Ex. 1032 ¶¶ 5–6; Ex. 1033, 27:6–29:23; Ex. 2013 ¶¶ 70, 108). Konstantinos expressly teaches that the “evolving market for data and programming services will demand that receivers have the capability of multi-channel tuning.” Ex. 1010 ¶ 1. Petitioner has thus established that there was market demand that would have led a POSITA to improve Kamieniecki with Konstantinos’s multi-carrier capability. See KSR, 550 U.S. at 418 (“Often, it will be necessary for a court to look to interrelated teachings of multiple patents; the effects of demands known to the design community or present in the marketplace; and the background knowledge of a [POSITA], all in order to determine whether there was an apparent reason to combine the known elements in the manner claimed by the patent at issue.” (emphasis added)). Moreover, we agree with Petitioner that Konstantinos addresses the cost and complexity issues that Patent Owner asserts are problematic. Pet. 35–36; Pet. Reply 8–9 (citing Ex. 1010 ¶¶ 102, 105–106). For example, Konstantinos teaches that breaking up the original signal into smaller subsignals decreases the required sampling rate for each band since interleaved lower-rate samplers can be used, which reduces power consumption and interference, and enables conventional digital channel selection methods to be used for fine selection of one channel from a band of channels. Ex. 1010 ¶¶ 102, 104105. In addition, Konstantinos teaches reducing cost and complexity through a single chip solution. Ex. 1002 ¶ 150; Ex. 1010 ¶ 44. Hence, we do not see the cost or complexity issues that Patent Owner mentions as barriers that would have prevented a POSITA from making the combination. Similarly unavailing is Patent Owner’s stance that Kamieniecki is satisfactory for the applications for which it is designed such that a POSITA would not seek to improve it with Konstantinos. PO Sur-Reply 8–11. Konstantinos recognizes the market demand for multi-channel functionality, so adding this capability to Kamieniecki’s single-channel device would have been a natural thing for the POSITA to pursue in light of the advantages afforded thereby. Ex. 1010 ¶ 1; KSR, 550 U.S. at 420 (“any need or problem known in the field of endeavor at the time of the invention and addressed by the patent can provide a reason for combining the elements in the manner claimed”).” slip op. at 17

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. Lynk Labs, Inc. v. Samsung Elecs. Co., 125 F.4th 1120, 1127 (Fed. Cir. 2025). Thus, Petitioner asserts permissible grounds of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–20 are unpatentable under 35 U.S.C. § 103(a) on the basis of Ho, which is a prior art printed publication, and either Aoki or Kim.” slip op. at 11

    “reciting “a processor operatively coupled to evaluate a seal quality of the earpiece based on seal quality measurements made while driving or exciting a signal into the speaker located in the earpiece.” To construe this phrase, we start with the claim language itself. The claim language requires that the “processor” is operatively coupled “to evaluate a seal quality of the earpiece,” indicating that the processor evaluates seal quality. The claim also states that this evaluation is performed “based on seal quality measurements made while driving or exciting a signal into the speaker located in the earpiece,” indicating that the processor uses seal quality measurements to evaluate seal quality. The phrase “while driving or exciting a signal into the speaker located in the earpiece” modifies “seal quality measurements made,” indicating the timing of when the seal quality measurements are made, namely while (at the same time as) a signal is driven or excited into the speaker. This “while driving or exciting . . .” clause does not specify what component performs the “driving or exciting a signal into the speaker located into the earpiece.” Significantly, although the claim language states that the processor “evaluate[s] seal quality,” it does not state that the processor drives or excites the signal into the speaker. Had the applicant wanted to limit the claim in that manner, it could have drafted it to specify that the seal quality measurements are made “while the processor is driving or exciting a signal into the speaker.” The applicant, however, did not do so. Indeed, elsewhere in the claim, the language clearly specifies that certain functions are carried out by the processor, for example: • “a processor operatively coupled to evaluate a seal quality of the earpiece” (claim [1b]); • “the processor is configured to generate a visual or audio message identifying whether the at least one earpiece is properly sealed” (claim [1c]); • “the processor by way of the speaker and microphone adjusts the audio” (claim 3); • “the processor measures differences in a further sound pressure level between an ambient microphone and the [earpiece] microphone, and determines a sealing profile of the ear canal” (claim 4); • “the processor determines whether the earpiece is properly inserted . . . and generates the visual or audio message identifying compliance” (claim 5); • “the processor by way of the speaker and microphone in the earpiece performs in-situ measurement of a user’s ear anatomy” (claim 6); and • “the processor monitors changes in the ECTF to determine a sealing level of the earpiece” (claim 7). Ex. 1001, 13:25–67. Claim 1, however, does not include any comparable language specifying that the processor performs the “driving or exciting a signal into the speaker located in the earpiece.” Therefore, we find that the plain and ordinary meaning of claim 1’s language does not require that the processor itself must drive or excite a signal into the speaker.” slip op. at 19

Dr. Struck does not discuss the grammar and structure of the claim language, including the fact that the phrase “while driving or exciting a signal into the speaker” modifies “seal quality measurements” and indicates the timing of when the seal quality measurements are made (while (at the same time as) a signal is driven or excited into the speaker). See id. Dr. Struck also does not discuss the fact that claim 1 recites that the processor “evaluate[s] a seal quality of the earpiece” but does not say that the same processor “driv[es] or excit[es] a signal into the speaker located into the earpiece, instead leaving the subject of what component performs the “driving or exciting” unspecified. See id. Indeed, Dr. Struck acknowledged at his deposition that his declaration lacks an “analysis of the grammar used in the limitation of [c]laim 1” at issue here. Ex. 1027, 20:4–15. Additionally, Dr. Struck appears to assume that the “driving or exciting” must be performed by some “other component mentioned in claim 1,” but there is no requirement that the claim must specify a particular component for carrying out this function.

    “We also agree with Patent Owner that, in Petitioner’s proposed combination, the above rule that gates off the ear canal microphone would frustrate Allen’s purpose of comparing the signals from the inner and outer microphones to determine a reverse transfer function and perform a seal fit analysis. See PO Resp. 53–54; PO Sur-reply 13. In reaching this conclusion, we credit the testimony of Mr. Struck that “[w]hen this rule is in force, the Allen-Victorian combination would not be able to measure a reverse transfer function” and, accordingly, “would be incapable of performing the automatic adjustments that the Allen hearing aid can perform based on the reverse transfer function.” Ex. 2006 ¶ 114. Dr. Kyriakakis also confirmed at his deposition that, when this rule is in effect, Allen would not be able to use the reflectance method, which relies on signals from the inner and outer microphones: Q: So while the rule at Column 10, lines 19 through 22, of Victorian is being employed, Allen is not able to solve any of the problems that it solves by the reflectance method; is that correct? A: If Allen doesn’t have access to the signals, that is correct, to the two microphone signals. Ex. 2007, 63:16–23. We are not persuaded by Petitioner’s argument that Victorian’s VOX circuit would not interfere with Allen’s seal fit analysis, because Victorian states that gating off may cause microphone signals to be “blanked or substantially attenuated,” and “[s]ubstantial attenuation refers to an attenuation after which the attenuated sound does not cause any echo or tinging7 having an intolerable intensity.” See Pet. Reply 14–15 (citing Ex. 1013 ¶ 32; Ex. 1027, 120:1–8, 121:3–9). As noted above, the Petition relies on the embodiment of Victorian’s VOX that “prevents the remote sound from being detected by ear canal microphone 440,” rather than an embodiment that simply attenuates that sound. See Pet. 46; Ex. 1002 ¶ 152; Ex. 2007, 61:2–16. Petitioner’s shift to relying on a different embodiment of Victorian that “substantially attenuat[es]” the sound rather than blocking it is a new argument that is presented for the first time in Petitioner’s Reply, and we therefore need not consider it. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019), at 73 (“Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.”). 8 Moreover, 7 The quoted portion of Victorian refers to “tinging,” but this appears to be intended to refer to “ringing.” For example, the previous sentence states that “[b]lanking refers to a substantially complete blockage of a sound, or in other words, that a detected sound is practically ignored by processor 460 such that it does not cause any echo or ringing which is audible by an ear.” See Ex. 1013 ¶ 32 (emphasis added). 8 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated.” slip op. at 52

    “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.

    “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.

    “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.

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

    “[t]he words of a claim are generally given their ordinary and customary meaning as understood by a person of ordinary skill in the art when read in the context of the specification and prosecution history.” Thorner v. Sony Comput. Entm’t Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012) (citing Phillips, 415 F.3d at 1313). “There are only two exceptions to this general rule: 1) when a patentee sets out a definition and acts as his own lexicographer, or 2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution.” Id. (citing Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1580 (Fed. Cir. 1996)). Neither of those exceptions apply here, and for the reasons below, we disagree with Patent Owner that the plain and ordinary meaning of “selecting a filter to apply” excludes determining whether or not to apply a given filter. We begin with the claim language at issue. TQ Delta, LLC v. DISH Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). When considering the language of the claim overall, the usage of “selecting a filter” in the claims does not in any way indicate whether the filter has to be selected from among multiple filters. Claim 1 recites “selecting a filter to apply to determined level of detail.” Ex. 1001, 13:20–22 (emphasis added). Patent Owner argues that “the claim language confirms that ‘selecting a filter’ means choosing from a number of alternative filters, not merely deciding whether or not to apply a filter,” (PO Resp. 34), but we see nothing in the claim language that suggests such a requirement. Patent Owner also points us to claim 19, arguing that selecting is not merely deciding whether to apply a filter, “since that determination is already made in [c]laim 19 by virtue of the initial sub-step of ‘exceed[ing] the threshold.’” Id. Again, we see nothing in claim 19 that suggests the determination of the threshold being exceeded requires a specific manner of filter selection. Instead, similar to claim 1, claim 19 recites: “when the level of detail exceeds the threshold, selecting a filter to apply to predetermined pixels.” Ex. 1001, 16:8–9. Thus, we are not persuaded that the claim language necessarily requires selecting a filter from among multiple filters. slip op. at 14

    “because Vehviläinen performs additional analysis before selecting a moderate or high activity filter, it does not teach selecting from among multiple filters. As discussed above, we do not agree with Patent Owner’s claim interpretation, and even if we did, we are persuaded that a person of ordinary skill in the art would have easily modified Vehviläinen’s filter selection to use a single area, e.g., the smooth area of Figure 5A, and a decision branch based on the level of detail for that single area. Vehviläinen discloses that “increasing the amount of selection branches makes the system more adaptive to the nature of the blocking effect but also increases control logic.” Ex. 1004, 8:15–27. Vehviläinen states that “[a] good embodiment,” but of course, “the invention can be utilized with less than three branches.” Id. at 8:18–21. Dr. Bove testifies that a person of ordinary skill in the art “would have been motivated to reduce complexity and the required control logic by using fewer branches, as taught by Vehviläinen, including for example just one branch, particularly for applications running on performance-constrained platforms such as low-end computer processors or mobile platforms, which often had constraints on thermal dissipation, power consumption, and cost.” Ex. 1003 ¶ 120 (citing Ex. 1004, 11:7–22). He further testifies that a person of ordinary skill in the art “would have been motivated to determine the level of detail for just the ‘smooth’ area and then select the smooth filter, if the area is smooth, or the high-activity filter otherwise.” Id. Dr. Bove illustrates that modification with the following pseudocode: if ( IsSmooth (Figure_5A) == TRUE) { Select (SmoothFilter); } else { Select (HighActivityFilter); } Id. He further testifies that such a modification would have been obvious and well within [a person of ordinary skill in the art’s] level of skill, and [such a person] would have had a reasonable expectation of success given that [the] modification involves a simple reordering of elements taught by Vehviläinen, the fact that Vehviläinen expressly teaches the have had with these basic filtering and thresholding techniques.

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
