      “Scope on Remand On remand, the panel here will not address issues outside the scope of the Federal Circuit’s mandate. See Hayward Indus., Inc. v. Pentair Water Pool & Spa, Inc., 814 F. App’x 592, 597 (Fed. Cir. 2020) (“The Board is bound by the terms of a mandate issued by an appellate court. Aydin Corp. v. Widnall, 121 F.3d 726, 1997 WL 413329, at *3 (Fed. Cir. 1997). ‘Unless remanded by [an appellate] court, all issues within the scope of the appealed judgment are deemed incorporated within the mandate and thus are precluded from further adjudication.’ Engel Indus., Inc. v. Lockformer Co., 166 F.3d 1379, 1383 (Fed. Cir. 1999).”). The sole issue on remand is whether “the evidence of copying” is sufficient to overcome the obviousness ground of unpatentability over Buruganahalli. Centripetal Networks, 19–20.

      “given to the Eastern District of Virginia court’s opinion because it was later vacated. The district court considered all of the Read factors (applying Read Corp. v. Portec, Inc., 970 F.2d 816, 826-827 (Fed. Cir. 1992)), of which only the first factor is directed to deliberate copying, although factors 2 and 9 bear indirectly on the issue of copying. The district court determined that “[t]he fact that Cisco released products with Centripetal’s functionality within a year of these meetings goes beyond mere coincidence. Therefore, the fact that Cisco’s system mirrors the functionality of the Centripetal patents is compelling evidence that damages should be enhanced for copying.” Ex. 1027, 157. Without more, it is difficult to evaluate the processes that the district court employed to reach its determination. As the Federal Circuit instructed, we need “not [] go searching throughout the entire litigation record to find the evidence of copying, but [we have] an obligation to consider the specific evidence that was put before” us. Centripetal Networks, 19. We continue to determine that the vacated finding of the district court should be provided little weight, especially in view of the strong case of obviousness discussed above. Examination of Aaron Striegel We also do not find the Aaron Striegel’s testimony to be particularly persuasive. The testimony provides statements such as “I found evidence that it could be plausible,” “[s]o we can see the timeline is very plausible,” and “I found it very plausible that indeed that this technology could have made its way into these respective accused products.” Ex. 1029, 31:12–32:3. This testimony suggests the possibility of copying but does not demonstrate actual evidence of copying. At most, this testimony indicates that further consideration of the underlying evidence is warranted, but does little to support an ultimate finding of copying. Again, even taking this testimony as evidence of copying, it still must stand up against the strong case of obviousness discussed above.” slip op. at 40

      “The District Court did not provide an element-by-element analysis of how the claims of the ‘856 Patent cover this description. See Ex. 1027, 41. However, from the description, we understand the Court to have concluded that the system receives rules, identifies a set of packets as part of a flow using the NetFlow logs, “determines” that encrypted packets in the flow match known malicious signatures based on unencrypted data in other packets (e.g., data in the SNI), and then filters the flow based in a URI (e.g., that from the SNI), routing it to the null interface. The Court does not describe how the system “determines” that encrypted packets match known malicious signatures based on information in unencrypted packets, but we assume that is done as in the ‘856 Patent, by correlation, i.e., an encrypted packet is “determined” to match a threat indicator if it is in the same flow as a packet with unencrypted information that matches the threat indicator.10 With that understanding, we conclude that the allegedly infringing system operates, as least at the level described in the court’s decision, in the same way Buruganahalli’s system operates, filtering encrypted packets due to their presence in a flow that includes packets with unencrypted data, such as in a handshaking packet. It follows that Patent Owner is unable to establish a nexus, because “[w]here the offered secondary consideration actually results from something other than what is both claimed and novel in the claim, there is no nexus to the merits of the claimed invention.” Novartis AG v.

Given that this is a press release by a company announcing that company’s new commercial product, however, we 8 The concurrence reevaluates Patent Owner’s evidence of industry praise and nexus, but we deem such considerations outside the remit of the Federal Circuit’s remand. are reluctant to give the “unsolvable” characterization much weight, as it may amount to puffery. But beyond that, it appears that the problem identified as “unsolvable” in the press release––“detect[ing] known attack signatures even in encrypted traffic”––had, in fact, already been solved in Buruganahalli, using the very same hello message, flow correlation, and man-in-the-middle techniques described in the ‘856 Patent. We thus cannot say that the press release identifies a long-felt need that was actually unsolved. See ZUP, 896 F.3d at 1374 (explaining that “[w]here the differences between the prior art and the claimed invention are . . . minimal . . . it cannot be said that any long-felt need was unsolved”) (quoting Geo.

(quoting Ex. 1004 ¶ 72). Petitioner asserts that a POSITA would have been motivated “to incorporate Larsen’s solution of connecting light applicators by hinges, to allow for adjustability of Lundahl’s device to provide the desired irradiance and irradiance uniformity to all target areas during PDT.” Id. (citing Ex. 1015 ¶ 127). According to Petitioner, a “POSITA would have had a reasonable expectation of success in combining Lundahl with Larsen, because both references describe similar illuminators for using light to treat conditions on a patient’s skin.” Id. at 31 (citing Ex. 1015 ¶ 128). Petitioner’s proposed modification of Lundahl also involves using LEDs as a light source instead of Lundahl’s fluorescent tubes. Id. According to Petitioner, a POSITA would have been motivated to make this change because: (1) LEDs had a lower cost and a longer lifetime than fluorescent tubes; (2) fluorescent tubes were known to have inconsistent light output within the tube itself; and (3) “the use of LEDs would be more practical to reduce spacing between light sources and the edges of the panels, as opposed to the bulky metal couplings at the end of fluorescent tubes, to reduce optical dead space across the light surface.” Id. (citing Ex. 1014, 4:41–42, 6:31–42; Ex. 1015 ¶ 129). Petitioner asserts that a POSITA would have had a reasonable expectation of success with this modification because Lundahl and Larsen “describe similar illuminators and the conversion from fluorescent tubes to LEDs was a routine practice prior to 2015.” Id. at 32 (citing Ex. 1015 ¶ 131). Patent Owner does not meaningfully dispute the Petitioner’s proposed reasons to combine Lundahl and Larsen. See generally PO Resp. To the extent Patent Owner argues that a POSITA would not have been motivated to make the combination because it would negatively affecting uniform illumination (PO Resp. 24), the motivating benefit here—using adjustable LED panels instead of monolith fluorescent tubes—outweighs the alleged disadvantages for the many reasons given by Petitioner, including greater adjustability and improved LED performance.

      “Patent Owner further argues that Petitioner’s reasoning (i.e., that it would have been obvious to try placing the hinges on the inner side surfaces) is unsupported and conclusory. PO Reps. 53–54. Patent Owner argues that Petitioner fails to identify a single prior art reference showing hinged structures on inner side surfaces. Id. This argument ignores that Larsen expressly identifies hinges on at least bottom side surfaces, and Petitioner merely proposes modifying their location from the bottom sides to inner sides. We find credible Dr. Grove’s testimony that relocating hinges would have been within the level of ordinary skill in the art. Ex. 1015 ¶ 155. Dr. Jokerst testifies that a POSITA would have been discouraged from placing hinges between Larsen’s adjustable applicators, because the hinges would create gaps that interfere with uniform illumination as well as the panels’ wiring, and create issues with the use and alignment of the panels. Ex. 2050 ¶ 175. However, a system with discrete panels connected by hinges (like in Larsen) will already have wiring, use and alignment technical challenges, regardless of the location of the hinges— the expected consequence of connecting multiple movable electronic panels. Moreover, the ’028 patent acknowledges in its discussion of conventional illuminators that placing hinges between panels was already known. Ex. 1001, 2:7–15. With respect to Dr. Jokerst’s opinion that the hinges would create gaps negatively affecting uniform illumination, we are persuaded that it would have been within the skill of a POSITA to locate the hinges on the inside surfaces “in a nearly flush arrangement,” such that the gaps would be minimized. Id.; Ex. 1015 ¶ 155. We also credit Dr. Grove’s supplemental testimony on this issue, directly refuting Dr. Jokerst’s testimony regarding gaps and uniform illumination (and therefore within the proper scope of reply, contrary to Patent Owner’s argument otherwise (Mot. 9).

      “Petitioner also fails to provide sufficient rationale and a reasonable expectation of success in combining Krishnan and Lee to arrive at a quality assessment neural network configured to receive an image. See Pet. 34–37. For example, the Petition lacks an explanation of why a POSITA would have been motivated to modify Krishnan’s quality assessment neural network to be configured to receive an image, instead of extracted features, in view of Lee’s image-receiving category classifying neural network. Id. Without such further explanation, Petitioner’s challenge falls short. Petitioner’s argument that neural networks for image quality assessment were “well-known” is not persuasive—it does not address the particular scope of limitation 1i, which also requires that the neural network is configured to receive images. Pet. 35 (citing Ex. 1002 ¶¶ 47–51, 118; Exs. 1017, 1023, 1024, 1026). Petitioner’s argument that combining Krishnan and Lee “would merely amount to applying known work from the field . . . to yield predictable results” is not persuasive because the Petition ties this reasoning to modifying Krishnan with Lee’s view-category-specific assessment parameters, not modifying Krishnan’s quality assessment neural network to receive images instead of extracted features.

      “We agree with Patent Owner that the recited second type SIBs exclude first type SIBs. The plain meaning of “first type” and “second type” indicates that the first type and second type are different in kind. RMTA 22 (App. A). Our interpretation is consistent with the Specification, which explains that second type SIBs exclude first type SIBs. As Patent Owner points out, the ’958 patent discloses “first type of system information (1TYP SIB) is . . . essential . . . for initial system access” and “second type of system information (2TYP SIB) is nonessential system information . . . defined as all other types of information, and thus excludes the [] information required for initial access.” Id. at 11–12 (citing Ex. 1001, 8:34– 46); see also Ex. 1001, Abstract (interchangeably using the terms second type and non-essential). Despite Petitioner’s argument that this disclosure is non-limiting and directed to a disclaimed example embodiment (Opp. 8–9), Petitioner could not identify any embodiment, among the approximately forty disclosed embodiments, describing something other than the first type SIB being essential information and the second type SIB being non-essential information. Tr. 22:18–26. Even the Petition acknowledges that “the ’958 Patent further classifies a second type of system information, the ‘non-essential’ SI, which is defined as all other types of information excluding that first type of information required for initial access.” Pet. 5. Furthermore, the prior art of record suggests that a person of ordinary skill would have understood second type SIBs exclude first type SIBs. See Ex. 1008 ¶ 48 (describing two categories of system information, “essential SI” and “Other SI”). Patent Owner’s expert also understood the recited first and second type SIBs as being mutually exclusive. See Ex. 1011, 49:10–13.

Petitioner similarly failed to address adequately where Lee discloses or suggests the recited “compressed format” and “plural parameters.” See Opp. 16–17. Aside from the above concerns, we also do not see sufficient explanation with respect to limitation 7h’s requirement that the transmitting by broadcast be based on a comparison of the value tag. Petitioner argues that, because Patent Owner does not dispute limitation 7g, “it would have been obvious to a POSITA to use the same value tag[] to determine the system information broadcast in Lee’s compressed format embodiment.” Pet.

The Petition is unclear as to which McGregor device is being referenced, e.g., the smart card of Figure 2, the wallet embodiment of Figure 4, or some combination of embodiments disclosed in McGregor and Palmer. Id. Regardless, the proposed modification of McGregor in view of Palmer, as we understand it, is based on conclusory reasoning and appears to be motivated by hindsight rather than the teachings of the applied references. Prelim. Resp. 38–40 (citing Ex. 2001 ¶¶ 97–102). 7 Ground 2 challenges independent claim 11 for asserted obviousness over McGregor, Palmer, and Tuttle. The Petition’s reliance on Tuttle for its teaching of distinct data transmitter, data receiver, and cue receiver ports does not alter our analysis for claim 11. Pet. 55–62. POSITA would have understood that a series of instructions would be programmed into McGregor’s microprocessor to function as a switching element (pursuant to Palmer’s teachings), and as described.in the ’333 Patent. See Claim [1(b)]; see ’333 Patent, 6:9-14. Accordingly, McGregor’s microprocessor is a switching element (1) that is placed into an activated state after receiving a handshake signal (an activation cue) that establishes a communication during the handshake process and (2) that remains in an inactivated state if no reader/writer device is detected (no activation cue). Ex. 1003 ¶ 127 (emphases added). Dr. Buehrer’s citation to the ’333 patent, without explaining his mapping of limitation [1(e)] onto McGregor-Palmer beyond a general reference to 10-plus pages of limitation [1(b)] “control device” analysis, suggests hindsight reasoning.

The Petition’s analysis, moreover, does not address why or how McGregor’s microprocessor would “accordingly” act as a data conveyance switching element or why a POSITA would want to program McGregor’s microprocessor to execute such a switching function in view of Palmer. We find the Petition and Dr. Buehrer’s testimony lacking in articulated reasoning supported by rational underpinnings sufficient to support the conclusion that limitation [1(e)] reads on the proposed McGregor-Palmer combination.

Pet. 28–31 (citing Ex. 1003 ¶¶ 95–105), 41–42 (citing Ex. 1003 ¶¶ 125–127). The Petition is unclear as to which McGregor device is being referenced, e.g., the smart card of Figure 2, the wallet embodiment of Figure 4, or some combination of embodiments disclosed in McGregor and Palmer. Id. Regardless, the proposed modification of McGregor in view of Palmer, as we understand it, is based on conclusory reasoning and appears to be motivated by hindsight rather than the teachings of the applied references. Prelim. Resp. 38–40 (citing Ex. 2001 ¶¶ 97–102). 7 Ground 2 challenges independent claim 11 for asserted obviousness over McGregor, Palmer, and Tuttle. The Petition’s reliance on Tuttle for its teaching of distinct data transmitter, data receiver, and cue receiver ports does not alter our analysis for claim 11. Pet. 55–62. POSITA would have understood that a series of instructions would be programmed into McGregor’s microprocessor to function as a switching element (pursuant to Palmer’s teachings), and as described.in the ’333 Patent. See Claim [1(b)]; see ’333 Patent, 6:9-14. Accordingly, McGregor’s microprocessor is a switching element (1) that is placed into an activated state after receiving a handshake signal (an activation cue) that establishes a communication during the handshake process and (2) that remains in an inactivated state if no reader/writer device is detected (no activation cue). Ex. 1003 ¶ 127 (emphases added). Dr. Buehrer’s citation to the ’333 patent, without explaining his mapping of limitation [1(e)] onto McGregor-Palmer beyond a general reference to 10-plus pages of limitation [1(b)] “control device” analysis, suggests hindsight reasoning. Id; see also Pet. 42 (generally referring to limitation [1(b)]). The Petition’s analysis, moreover, does not address why or how McGregor’s microprocessor would “accordingly” act as a data conveyance switching element or why a POSITA would want to program McGregor’s microprocessor to execute such a switching function in view of Palmer. We find the Petition and Dr. Buehrer’s testimony lacking in articulated reasoning supported by rational underpinnings sufficient to support the conclusion that limitation [1(e)] reads on the proposed McGregor-Palmer combination. See KSR, 550 U.S. at 418 (“there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”). The Petition does assert an obviousness theory within the analysis of the “control device” limitation [1(b)]. Pet. 25–35 (citing Ex. 1003 ¶¶ 85– 109). The Petition asserts that a “POSITA would have been motivated to implement McGregor’s device pursuant to Palmer such that the security code would be automatically transmitted when the device detects the receive the security code.” Pet. 28; see also id. at 31 (“A POSITA would have been motivated to implement Palmer’s (1) RF field detection and handshake processes and (2) Palmer’s transceiver hardware in McGregor’s device.”) (citing Ex. 1003 ¶¶ 95–105). We find the Petition’s obviousness theory to be inherently inconsistent and non-specific with regard to the “data conveyance switching element” recited in limitation [1(e)].” slip op. at 16

      “Alternatively, even if we set aside that timing issue, Dr. Liu’s bare opinion, advanced for the first time during cross-examination, that an epitaxial layer is “obvious” from Hirler’s disclosure is inadequate to support the challenges. Id. at 24–25. We accord little weight to Dr. Liu’s opinion because it is conclusory. See Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In any event, Petitioner does not meet, on this record, the “high standard” required to establish an inherent disclosure of an epitaxial layer in Hirler. PO Resp. 24.6 Dr. Liu opined for the first time during cross-examination “that it would have been impossible to create Hirler’s more lightly doped n- drift zone layer on top of its more heavily doped n+ substrate layer other than via epitaxy.” Id. at 25 (citing Ex. 2014, 164:16– 165:20). But Patent Owner effectively refutes that proposition with evidence that such a layer “could be created by counter-doping,” even if, as Dr. Liu contends, counter-doping may have been less ideal due to “disadvantageous mobility.” Id.

      “feature of scanning a wireless communication network by the mobile device receiving the streaming data for re-routing, to identify devices connected to the wireless network, are identified as capable to handle the routed media content.” Prelim. Resp. 5–6 (emphasis added) (citing Ex. 1002, 237–238). Thus, we understand the recited language to require scanning to find devices that have been identified as compatible, not just scanning to find devices and later determining which of those devices, if any, are compatible. Zhang, on the other hand, scans to find devices in the network, but that scan does not seek out devices identified as compatible. Specifically, Zhang scans to find its “helper environment” which is composed of “devices around them.” Ex. 1004, code (57); see also id. 2:16–20. The first step of Zhang’s process is to find “a local device [that] offers helper service.” Id. at 3:62–63. In the next step, Zhang then interrogates the device it scanned for in order to find out whether that device offers the necessary service. Id. at 3:63–4:5. In other words, Zhang is not scanning for compatible devices, but rather it is scanning for any device around it and then asking whether the device provides the necessary service. We find this to be insufficient because the claim is not merely seeking to identify a compatible device, but rather it is scanning “to identify a plurality of devices, identified as compatible to handle said media content.” Thus, for these claims it is not enough that the network be scanned for devices; instead, the network must be scanned for devices “identified as compatible.” The inclusion of Rofheart does not address this issue. Rofheart is relied upon to teach “that a local device identifies and connects with a plurality of remote devices.” Pet. 29. According to Petitioner, one of ordinary skill in the art would have used Rofheart’s teaching to improve Zhang by adding “the benefit of providing users control to select one or more of a plurality of devices, rather than always connecting to the first identified available compatible device, as taught by Zhang.” Id. As such, neither of the cited references addresses the recited scanning for devices identified as compatible.” slip op. at 21

Resp. 2–3. In other words, Patent Owner argues that the person of ordinary skill would have had less education and more specific experience with mobile devices, including multimedia streaming, than Petitioner proposes. Because Petitioner’s argument is supported by declaratory testimony, and Patent Owner does not provide supporting evidence for its argument, we adopt Petitioner’s articulation of the level of ordinary skill in the art.

      “Although Petitioner doesn’t promote it in its Petition, we agree with Petitioner’s undisputed contention that the ordinary and customary meaning of the “announcer device” limitation is that the “mobile communication device is receiving rerouted data from surrounding equipment, rather than rerouting data to surrounding equipment.” Pet. 19. This is in accord with the specification of the ’990 patent which states that “[t]he announcer device 30 is responsible for announcing to the environment the availability of a current device for accepting routed media.” Ex. 1001, 7:15–17 (emphasis added). The construction that Petitioner does promote, based on its interpretation of Patent Owner’s arguments in the parallel litigation, departs from the term’s ordinary meaning, yet Petitioner has presented no evidence to justify such a 7 Petitioner also argues that we should construe the term media transformer as a means-plus-function limitation invoking 35 U.S.C. § 112(f). Pet. 7–11. We need not construe this term to reach our decision not to institute trial in this proceeding. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

We are aware of no evidentiary basis for Petitioner’s proposed construction in the specification or prosecution history of the ’990 patent. To the extent, if any, that Patent Owner may have argued in the parallel district court proceeding for a departure from the term’s ordinary meaning, we find no clear disavowal of the term’s scope, particularly in light of Patent Owner’s ultimate argument that the term should have its “[p]lain meaning.” Ex. 2008, 2.” slip op. at 12

      “In light of our disagreement with Petitioner’s proposed claim- construction, we do not find persuasive Petitioner’s argument that Chihara teaches the “announcer limitation,” either alone or in light of BluetoothSpec. Although Petitioner shows that Chihara’s phone 11B announces its availability for pairing with nearby Bluetooth-compatible devices, Petitioner does not argue that phone 11B indicates availability to receive any rerouted data from either headset 13 or watch 12B. To the extent that phone 11B receives data for rerouting, it appears to receive it from a mobile or fixed communication network, not from any surrounding Bluetooth devices. See, e.g., Ex. 1004 ¶¶ 79 (phone 11B receives video and audio data via “a fixed telephone network or another mobile telephone set accommodated in a mobile communication network,” and transmits that streaming data to watch 12B and headset 13), 53–54 (calls arrive via mobile telephone antenna 26, which are then processed and transmitted via Bluetooth antenna 21 to watch 12). Regarding the bidirectional communication between phone 11B and headset 13 or watch 12B, Petitioner has not pointed to any evidence that the data sent from watch 12B or headset 13 to phone 11B includes rerouted data. Similarly, Petitioner’s contention that Chihara’s phone 11B, in light of BluetoothSpec, indicates its availability (e.g., that the phone is “powered on” and transmits signals to discover nearby devices) fails to meet the plain language of claim 1, which requires the streaming device (phone 11B) to indicate its availability to receive rerouted data from the surrounding devices (headset 13 or watch 12B). Thus, we determine that Petitioner has failed to show that Chihara, in view of BluetoothSpec and the other references, teaches the “announcer device” limitation. Therefore, Petitioner has not shown that it would be likely to prevail if we instituted an inter partes review.” slip op. at 17
