“For purposes of this Decision, we adopt Petitioner’s definition of a POSITA. Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook).

Petitioner’s assertions that this would be the case consist solely of conclusory statements, supported only by citations to Mr. Cook’s declaration. Mr. Cook, however, simply repeats Petitioner’s conclusory statements, without providing sound technical reasoning supported by objective evidence to explain and support his opinions.

As discussed above, Mr. Cook is qualified to opine from the perspective of a POSITA on technical matters included within the expertise of a person meeting Petitioner’s definition of a POSITA, which do not include optics and optical apparatus. We, therefore, credit Dr. Klopp’s opinion over that of Mr. Cook on this particular factual issue of how it is directly related to optical systems and methods about which Mr. Cook possesses limited relevant experience.

“In determining the level of ordinary skill in the art, various factors may be considered, 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.

Patent Owner’s proposed skill level overlaps with Petitioner’s proposed skill level, and any differences would not alter the outcome of this proceeding. Therefore, we adopt Patent Owner’s proposed skill level with two modifications.

“to determine a characteristic [of the chick] . . . [that] manifests in one of two or more possible states, e.g., sex (male vs. female), health (healthy vs. unhealthy), genetic mutation (present vs. not present).” Reply 13 (citing Ex. 1004, 3). The recitation of a generic “database of images” does not distinguish limitation [1.4] from the asserted combination of Gershman-Pierre, particularly in view of Pierre’s disclosure of “a computerized processing process is implemented in order to compare the captured images to reference images,” as asserted in the Petition. Ex. 1004, 3 (emphasis added); see Pet. 23–24 (citing Ex. 1003, 2–5; Ex. 1004, 3, 5). Thus, we find that storage of Pierre’s reference images of male and female wing feathers in a database used for comparison in Gershman’s computerized digital chick image processing system would have been obvious to a POSITA and satisfies limitation [1.4].19 We agree with Petitioner that it would have been obvious and well within the skill level of a POSITA—someone with a Bachelor of Science degree in agricultural, industrial, or electrical engineering and two years of experience in industrial poultry sexing and/or image processing (Resp. 20)—to store reference images as taught by Pierre in a “computerized processing” database. The rationale argued by Petitioner, to organize the collection of reference images for comparison to determine whether the characteristic of interest was present, finds direct support in Gershman and Pierre. Both references disclose comparing digital images of a chick’s wing feathers to reference data (Gershman) or reference images (Pierre) of male and female chick wing patterns. Pet. 23–24; Reply 12–13.

“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).

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.

“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.

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.

“The ’567 patent is directed to a using a thermostat to detect faults in the HVAC system. See Ex. 1001, code (57). That aligns more closely with and HVAC control systems—than the one proposed by Petitioner—which focuses on energy controls. Compare Ex. 2002 ¶ 27, with Ex. 1002 ¶¶ 31– 33. Accordingly, we adopt Patent Owner’s propose definition. However, we consider the parties’ positions to be substantially similar, and note that neither party argues that the level of skill is determinative to the outcome of the case. Accordingly, we would have reached the same factual findings and conclusions of law had we adopted Petitioner’s proposed definition.” slip op. at 9

“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. Testimony which goes into more detail and expands on the points made in the papers (but not going beyond the points made in the papers) is more helpful and, as a general matter, given more weight so long as it is consistent with, and supported by, the other evidence in the record.” slip op. at 11

In light of the record before us, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art.

Pet. Suppl. Br. 4–5. Claim 1, however, recites “an automobile charger, comprising . . .” which is an open-ended term, meaning that claim 1 is not limited to only the connections expressly recited therein. Petitioner’s arguments do not address this open-ended aspect of the plain language of the claims. Petitioner also argues that the language of claim 3 is consistent with its construction because claim 3 “places the switching circuit between the second pole of the first battery . . . and the second lead of the load.” Pet.

“After considering the parties’ arguments and evidence, we find Petitioner has established, by a preponderance of the evidence, that claim 4 is unpatentable as obvious in view of Yu and Thomason. As discussed above, we disagree with Patent Owner’s arguments regarding negative pole switching, and find that Petitioner presents persuasive evidence that Yu teaches or suggests the limitations of claim 1. Petitioner also presents undisputed evidence that Yu and Thomason teach or suggest the additional limitations in claim 4. Pet. 52–54. Additionally, Petitioner directs us to a disclosure in Thomason itself regarding a protection mechanism to prevent the jump starter from self-destructing, and presents testimony from Dr. Kirtley that a person of ordinary skill in the art would have considered Thomason’s teaching in order to avoid damage to Yu’s internal battery, and would have been able to implement Thomason’s teachings.

In view of Petitioner’s persuasive evidence demonstrating where the prior-art references teach or suggest each limitation in the challenged claims, and explaining why a person of ordinary skill in the art would have had reason to combine the prior-art references with a reasonable expectation of success, we find Petitioner has established, by a preponderance of the evidence, that claim 4 is unpatentable as obvious in view of Yu and Thomason.” slip op. at 33

“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

But, because we find that Petitioner has shown that Chin suggests implementing its invention in an IC9 package substrate as Patent Owner’s proposed construction would require (infra § III.D.2.), we need not resolve this dispute. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Patent Owner advocates limiting the scope of this claim term to include only the contact pads in a particular location (i.e., the PCB-side of the IC package substrate),10 but the intrinsic record does not support importing such a limitation into the claim. Patent Owner identifies (and we perceive) no passage in the intrinsic record that redefines the term “contact pads” or disavows part of its scope. See Thorner v. Sony Computer Ent. Am.

“we agree with Petitioner that Chin explains that its “concepts apply equally to an integrated circuit package substrate.” Pet. 22. In particular, we find that Chin discloses an IC package substrate. See Ex. 1004, 1:61–62 (referring to “a substrate used inside a BGA package”); see also Ex. 1003 ¶¶ 28–30 (Dr. Choi explaining that a BGA is a type of IC package). We credit Dr. Choi’s testimony on this point because it is logical and supported by cited evidence. See, e.g., Ex. 1014, 45;12 Ex. 1016, 5–7. We are also persuaded that Chin expressly suggests implementing its invention in an IC package substrate. Chin begins its description by stating that “[t]he present invention relates generally to the design and fabrication of printed circuits and multi-layered substrates.” Ex. 1004, 1:7–8 (emphasis added). Chin also states that its invention “is illustrated by way of example, and not by way of limitation,” in its figures. Ex. 1004, 3:26–27. Similarly, Chin’s final paragraph states that alternative implementations “will be apparent to those skilled in the art,” and it states that “semiconductor implementations . . . are contemplated as within the scope of the present invention” as they use “similar layered printed circuit routing techniques.” Ex. 1004, 5:54–6:10. Moreover, as background for its invention, Chin addresses problems encountered as signal speed increases and explains that “excess parasitics that limit the bandwidth” are caused by an impedance mismatch between landing pads and their associated interconnect conductors. Ex. 1004, 1:35–56. Chin then states: One example is the use of a ball-grid-array (BGA) package in a multi-gigahertz printed circuit board. The landing pads of current state of the art BGAs are typically 25–30 mils in 12 Unless otherwise noted, our citations refer to page numbers added to an exhibit by Petitioner or Patent Owner rather than the document’s native page numbers. diameter, which is significantly larger than the typically 5 mil microstrips used in interconnecting conductors. Another example is a substrate used inside a BGA package. Typical solder ball landing pad sizes for current technology BGA substrates are on the order of 20–25 mil, significantly larger than the typically 3 mil traces used in microstrip interconnects. Ex. 1004, 1:56–65 (emphasis added). Accordingly, given the context provided by Chin (see Ex. 1004, 1:7–8, 5:54–6:10), we find that a person of ordinary skill in the art would have understood this passage (see Ex. 1004, 1:61–65) to suggest applying Chin’s disclosure to an IC package substrate.
