Nor does Petitioner respond to our inquiry about whether collateral estoppel maybe applied on a limitation by limitation basis. See Pet. Reply 27. At the hearing, however, Petitioner confirmed that resolution of the issue is not necessary to our final determination. JUDGE ROSS: Do we even need to decide the collateral estoppel issue? I mean, it seems to me that if your petition clearly made out your case for the combination of Richardson and Zhao, then we don't even need to reach that. MR. CHANDRA: That’s exactly right, Your Honor. That is our position, as well. We believe collateral estoppel applies, but you don't need to decide that issue in order to find these claims unpatentable. As I mentioned before, these are the same references. We have fairly sought out all of the portions of Richardson, we cited to specific portions. Not just relying on collateral estoppel, but the teachings of the reference itself. So, while this is an issue, we believe that collateral estoppel should apply. It does not have to apply in order to find the challenged claims unpatentable. Tr. 19:9–20. We are persuaded, as discussed in Section II.G., that Petitioner has shown where Richardson in combination with Zhao meets each limitation of the claims of the ’203 patent. Accordingly, we need not address whether Petitioner has demonstrated sufficiently that collateral estoppel applies here.” slip op. at 14

We also find that the portions of Pogge cited by Petitioner show that its “void 25 has an important function in relieving stresses caused by differences in the thermal coefficient of expansion (TCE) of the various materials in and around the feature” (Ex. 1005 ¶ 27) and that the portions of Edelstein cited by Petitioner show that, “[a]lthough it does not change the thermal expansion coefficient, the introduction of a void or voids reduces the effective modulus and Poisson ratio of the through-via, resulting in a compliant through-via that exerts much less stress and force on the surrounding structures” (Ex. 1006 ¶ 47). As discussed above, we find that Cooney’s void 25 is “entirely surrounded by” its conductive filler 24 that, in turn, is surrounded by liner 22 and substrate 10’. Ex. 1004, Fig. 6. We credit Petitioner’s relied-upon testimonial evidence that the presence of a void was known to reduce thermal stress in the surrounding substrate, because the citations to the record support it.

“Relying on the declaration of Dr. Wicker, Petitioner contends that a person of ordinary skill in the art (POSA) at the time of the invention of the ’687 patent would have had “at least a bachelor’s degree, or equivalent, in electrical engineering, computer engineering, computer science, or a related field or an equivalent number of years of working experience, and one to two years of experience in networking environments, including at least some experience with live-streaming network architecture.” Pet. 13 (citing Ex. 1001 ¶¶ 72–76).

“We agree with Petitioner’s contention that Ellis and Spivey differ in that Ellis uses HTTP request-response messages whereas Spivey uses websocket connections between the content delivery system’s server and user equipment. Pet. 18 (citing Ex. 1001 ¶¶ 106–115). As Petitioner points out, in Ellis’s HTTPS connections, a user equipment requests the server to respond with any new messages. Id. at 8 (citing Ex. 1001 ¶¶ 50, 51); Ex. 1016 ¶¶ 37, 40. We agree with Petitioner that Spivey’s websocket connections were a known alternative to HTTP requests. Id. (citing Ex. 1001 ¶¶ 52, 53, 58, 59). We further agree that such websockets constitute bidirectional, full-duplex, stateful, and persistent connections that provide instant updates from the server to the user equipment without the need for the user equipment to request them from the server (referred to as “push” technology). Id. Accordingly, we agree with Petitioner that, under some scenarios, a POSA would have viewed Spivey’s websocket connections as more advantageous for providing video content and event data to end-users than Ellis’s HTTP request-response protocol, thus motivating simple substitution of Spivey’s LDSD and MQSD for Ellis’s SCS. Pet. 21–22 (citing Ex. 1016 ¶¶ 34, 47; Ex. 1017 ¶ 34; Ex. 1001 ¶¶ 114, 115). See KSR, 550 U.S. at 417 (simple substitution of one known element for another is a recognized rationale supporting a motivation to combine). For example, if server requests are frequent, a POSA would have recognized that the processing overhead of setting up and tearing down HTTP connections would exceed any latency disadvantages of Spivey’s persistent websocket connections. Ex. 1064 ¶ 35. Thus, under some circumstances, a POSA would have been motivated to make the Ellis-Spivey combination, and we do not agree with Patent Owner’s arguments to the contrary.” slip op. at 19

As Petitioner points out, although Patent Owner argues that there is a long-felt need for a system that “allows broadcasters to deliver synchronized, low-latency digital content, such as a video content, and audio content . . . ” (PO Resp. 64), Patent Owner does not contest Petitioner’s showing that Ellis also discloses “a video streaming system that provided event information over a separate channel, which is not hard embedded in the video stream.” Pet.

“PO Resp. 30 (citing Ex. 2006 ¶ 58). Patent Owner’s proposal is too narrow in two respects. First, it mandates certain education and experience in RF neurotomy specifically. This is too narrow as the description of the scope of the invention set forth in the ’782 patent as described above is not limited to RF neurotomy. Second, it requires the POSA to be both a physician who performs thermal ablation (RF neurotomy specifically) and an engineer with training and experience “in the design and development of devices and methods” for performing the same. Id. This is too narrow because it excludes physicians and other advanced degree holders who research and design devices and methods for performing thermal ablation but do not actually operate on patients.

Patent Owner argues that Lee is not analogous art under the first criterion because “Lee does not relate to neurotomy at all.” PO Resp. 34. However, as discussed above, the field of the invention is not limited to neurotomy. The field of the invention is thermal ablation generally, which encompasses RF neurotomy, but which is not limited to RF neurotomy. Accordingly, we are not persuaded by Patent Owner’s argument.

“35. “Although § 103 does not, by its terms, define the ‘art to which [the] subject matter [sought to be patented] pertains,’ this determination is frequently couched in terms of whether the art is analogous or not, i.e., whether the art is ‘too remote to be treated as prior art.’” In re Clay, 966 F.2d 656, 658 (Fed.

However, as discussed above, the field of the invention is not limited to neurotomy. The field of the invention is thermal ablation generally, which encompasses RF neurotomy, but which is not limited to RF neurotomy. Accordingly, we are not persuaded by Patent Owner’s argument.

“processor” to the spare processor, we determine that the claim is describing this transfer of identification of “boot processor,” which is required when transferring a boot processor’s functions to a spare because of the “problems [that] arise in attempting to idle (or eject) the boot processor.” Id. at 6:25– 27. This is confirmed by the language of limitation [1d], stating that the switching of the role of boot processor involves “changing a system identifier of the spare processor to that of the boot processor.” Thus, the firmware and operating system exchange this information identifying the boot processor, which is described in the specification as a device tree. See, e.g., id. at 13:21–35. The ’302 patent makes clear that accurate identification of which processor is the boot processor remains critical during runtime. See, e.g., id. at 6:25–27. Thus, Patent Owner is correct in requiring the system to have a way to identify the boot processor and to transfer this identification during runtime. However, as made clear in the embodiments described in the ’302 patent discussed above, this identification is for runtime purposes to accommodate runtime problems, not for booting purposes. Although Patent Owner may be correct that a function of the boot processor is to boot the system (PO Sur-reply 5), the problem identified in the ’302 patent is a problem relating to the runtime reassignment of the boot processor identity, to address a runtime need to identify the boot processor. See, e.g., Ex. 1001, 11:6–9. Accordingly, based on our analysis of the claims and specification, we determine that “switching the role of boot processor to a spare processor without shutting down the system’s operating system” means causing the system to identify the spare processor as the boot processor (e.g., in a device tree), which then causes the spare processor to appear as the boot processor to the system during runtime. Ex. 1001, 6:25–41, 11:4–18 (describing why boot processors are treated differently even after the boot process has completed); compare id. at 9:65–11:3 (process for recovering from loss of lockstep of a non-boot processor without using a spare), with id. at 11:4–43 (process for recovering from loss of lockstep of a boot processor using a spare because boot processors, during runtime, need special treatment); see also 14:66–15:21 (emphasizing that spares are only needed for recovering boot processors). We construe switching a “role of boot processor” to mean transferring an identification in the system of which processor is the boot processor. This construction comports with the embodiments described in the specification. We do not adopt an additional requirement that this procedure also requires designating which processor will boot the system in the next reboot, which is not disclosed in the specification.” slip op. at 24

“may swap processors that are failing, and perform the necessary bookkeeping to keep the operating system informed as to how to address the processors available, nothing in the Petition persuasively explains whether this generic processor swapping switches the boot processor role. As we explained in our claim construction section, the term “boot processor” is not merely a label of convenience to describe the processor that happened to have earlier booted the system. The role of boot processor is specifically switched to the spare; it is a piece of information tracked by the system. As we explain below, Petitioner does not adequately address the transfer of this information to make the system aware of which processor has the boot processor role. Petitioner asserts that “the BSP flag” of the IA-32 system is used to “determine whether a processor is the boot processor.” Pet. 17–18. Petitioner here is relying on a register used in IA-32 processors to identify whether or not they are the boot processor. This register is used during booting so that only the boot processor boots the system. See, e.g., Ex. 1008, 238–40, 710. This register does not appear to serve any further role, and Petitioner offers no persuasive evidence or argument that the processor register flag is exposed or copied to the operating system or APIC table. Petitioner’s proposed combination does not involve updating this register, nor does Petitioner explain how, even if the register were updated, it would meet the “switching” a “role of boot processor” in limitation [1d].” slip op. at 32

“We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35

“said integrity is compromised, then also providing an indication of said compromised integrity.” Ex. 1001, 20:65–21:2. Although Petitioner points out that the limitation does not expressly recite “‘specifically’ monitoring the tight coupling” (Pet. Reply 8), the structure of the clause suggests that the tight coupling is specifically monitored. At a high level, the limitation is straightforward in its recitation that the integrity being monitored is “of the tight coupling” (Ex. 1001, 20:65–66 (emphasis added)), plainly suggesting that the tight coupling is specifically monitored. More granularly, breaking the relevant clause down to its grammatical parts, the clause recites a gerund (“monitoring”) acting on a direct object (“the integrity”) which is modified by a prepositional phrase (“of the tight coupling”). Notably, the object of the preposition (“of”) is “the tight coupling.” Altogether, this reads that the integrity being monitored is specifically of the tight coupling. Also, the claim recites that “if said integrity is compromised, then also providing an indication of said compromised integrity.” Therefore, from the claim language we know that the “integrity” of the tight coupling is something that may be “compromised,” which is consistent with Patent Owner’s proposed construction of determining whether the physical coupling has been “accessed or disturbed.” Petitioner’s interpretation effectively inserts additional language into the limitation such that the limitation includes monitoring the integrity of a device containing or surrounding the tight coupling, such as a camera (or camera housing), e.g., “monitoring the integrity of a camera that includes the tight coupling.” But, because the plain reading and the structure of the limitation reads that it is specifically the tight coupling’s integrity—not another physical structure, like a camera—which is being monitored, a monitored is not consistent with the language of the claim. See PO Resp. 9 (arguing that “Petitioner’s construction is improper because the claim language explicitly requires monitoring the physical coupling between the memory and the sensor as opposed to some third structure” (emphasis omitted)).” slip op. at 17
