“Although Patent Owner points to various parts of the ’518 patent as supporting its proposal, other parts of the patent are not so limited. For example, the ’518 patent repeatedly mentions prior art patents disclosing communication techniques applied to twisted pair wiring, including discrete multi-tone (DMT) modulation and bit loading. Ex. 1001, 3:49–50, 3:67–4:2, 8:19–26. The patent further mentions that its data network overlays cable or satellite services. See, e.g., id. at 5:1–6. Thus, a POSITA would not be limited to experience only with “coaxial cables” as opposed to work involving signal processing and/or communication systems/networks more generally. The ’518 patent describes the “Technical Field” as “broadband communication networks and specifically . . . communications using coaxial cable building wiring.” Id. at 1:25–30. We find it appropriate here to use the broader statement of “broadband communication networks” as the field of a POSITA’s experience. The challenged claims of the ’518 patent relate to a “data communication network” comprising “cable wiring” with “segments of coaxial cable.” Id. at 12:16–19. This does not mean that the “cable wiring” is strictly coaxial—only that it includes segments that are.” slip op. at 11

“The ’518 patent seeks to overcome channel impairments by using probe messages to characterize the communication channel and determine optimum bit loading. Ex. 1001, code (57). These impairments include signal reflections, ISI, and signal attenuation. Pet. Reply 9–10 (citing Ex. 1001, 3:5–19). Similarly, Isaksson estimates channel characteristics by periodic transmission of a base sync frame from one transceiver to another where it is compared with a reference frame. Ex. 1013, 10. Isaksson’s channel characteristics may include attenuation, phase shifting, and variance, which are similar to the problems identified in the ’518 patent. Id. Both the ’518 patent and Isaksson address the problem of ISI by using bit loading to transmit data using sub-carriers less affected. Ex. 1001, 3:5–20; Ex. 1013, 16, 35, 79. Hence, we find the problems identified in the ’518 patent and Isaksson of how to overcome channel impairments reasonably pertinent such that Isaksson is analogous art to the ’518 patent. We find unavailing Patent Owner’s arguments that the ’518 patent is specific to in-home networks with coaxial cables and splitters whereas Isaksson is restricted to twisted pair, point-to-point networks having no intervening devices and which are located outside of homes. PO Resp. 15– 20; PO Sur-Reply 21–24. Any such differences do not change the fundamental nature of the problems of noise and interference affecting these environments. Such differences go more toward the field of endeavor than the reasonable pertinence of the problems each address. See Pet. Reply 10 (citing Donner Tech., LLC v. Pro Stage Gear, LLC, 979 F.3d 1353, 1360 (Fed. Cir. 2020)). Specifically, both the ’518 patent and Isaksson address the problem of channel impairments such as interference (e.g., ISI) and noise, and use the solution of bit loading to overcome them. See, e.g., Ex. 1001, 4:42–47; Ex. 1013, 1:3–7, 6:17–20, 16:10–16, 79:5–14. Hence, we find that the ’518 patent and Isaksson are analogous art because Isaksson is reasonably pertinent to the problems addressed in the ’518 patent notwithstanding Patent Owner’s arguments. We do not reach the question of whether the two are in the same field of endeavor.” slip op. at 17
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“Kliger identifies the problems of splitter reflections causing inter- symbol interference, external noise, and dynamic network conditions adversely affecting home network communications. Pet. 23–24 (citing Ex. 1007 ¶ 73; Ex. 1010, 5; Ex. 1004 ¶¶ 65–68). Isaksson teaches using multi-carrier modulation, such as DMT and OFDM, to address frequency dependent loss and noise using synchronized bit-loading based on carrier SNR. Id. at 24 (citing Ex. 1004 ¶ 69; Ex. 1013, code (57), 26:4–20). We agree with Petitioner that the combination of Kliger and Isaksson amounts to the use of known techniques (Isaksson’s synchronized bit-loading) to improve similar devices in the same way (overcoming interference and maintaining connections with other modems). Id. at 26–27 (citing KSR, 550 U.S. at 415–421). We do not agree with Patent Owner’s argument that Kliger already solves the issues that Petitioner identifies such that a POSITA would not have looked to Isaksson’s synchronized bit-loading. PO Resp. 50. Petitioner has established that Isaksson’s solutions would improve Kliger’s modulation by determining the number of bits-per-carrier based on SNR, disabling noisy carriers, and synchronizing bit loading. Pet. 23–28; Pet. Reply 23–24. Hence, a POSITA would have been motivated to improve Kliger with Isaksson. See KSR, 550 U.S. at 417 (“if a technique has been used to improve one device, and a [POSITA] would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill”). Patent Owner alleges that Kliger’s network is coaxial whereas Isaksson’s is point-to-point, twisted pair with no intermediary devices such as splitters which would cause the interference, noise, and attenuation that the ’518 patent addresses. PO Resp. 50–55. However, we do not agree that these alleged differences would have precluded a POSITA from making the combination of references. “Signal impairments such as reflections, noise, attenuation, and inter-symbol interference (ISI) are common challenges in nearly all communication mediums.” Ex. 1036 ¶¶ 23–27. Communication networks experience these challenges, whether point-to-point or shared, twisted pair or coaxial, in-home or out-of-home, with or without splitters. Id. As Petitioner’s expert, Dr. Williams, puts it, “a POSITA can draw from the same toolbox of known solutions to address these impairments regardless of the medium.” Id. ¶ 27. Among those solutions is Isaksson’s approach of synchronized bit-loading. Moreover, Isaksson expressly states that “[i]t should be emphasized that the present invention can be used not only with the MUSIC system as herein described, but with other multi-carrier systems employing dynamic bit loading.” Ex. 1013, 72:5–8 (emphasis added); Ex. 1004 ¶¶ 81–82. Hence, a POSITA would have been led to consider using Isaksson’s synchronized bit-loading with Kliger’s coaxial network which uses a multi-tone transmitter to determine whether to transmit power on each particular tone. See, e.g., Ex. 1007 ¶ 166; Ex. 1013 1:1–7. Further facilitating the combination is Kliger’s disclosure of using “a regular multi-tone transmitter (either OFDM or DMT) to determine whether to transmit power on each particular tone wherein tones can be silenced (which is, in effect, a form of bit-loading). See, e.g., Ex. 1007 ¶¶ 6, 166, Fig. 1; Ex. 1013, 1:1–7, 3:24–34, 4:21–25, 16:8–12. In addition, Kliger expressly recognizes and seeks to address signal impairments caused by splitters, including poor signal isolation, return loss performance, degradation at higher frequencies, and inter-symbol interference due to reflections (the same problems the ’518 patent addresses). Ex. 1007 ¶¶ 61, 73. Accordingly, a POSITA would have been motivated to combine teachings of Kliger and Isaksson. Patent Owner argues that Petitioner did not explain how a control channel would exist across a coaxial splitter’s multipath signal. PO Resp. 56–58 (citing Pet. 26; Ex. 1013, 73:4–15, 74:22–31, Fig. 33; Ex. 2002 ¶¶ 147–148). Patent Owner does not explain why it would be necessary to use Isaksson’s control channel in Kliger, particularly when Kliger has its own control channel. Ex. 1007 ¶¶ 63–64, 166. Patent Owner’s argument amounts to bodily incorporation of Isaksson in Kliger, which is not a proper approach to obviousness. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). We further disagree with Patent Owner’s argument that Isaksson’s base sync frames (equivalent to the claimed probe messages) would not function in Kliger’s network. PO Resp. 58–60 (citing Pet. 26; Ex. 1007 ¶¶ 55–57; Ex. 1013, 24:8–28, Fig. 1; Ex. 2002 ¶¶ 149–154). Patent Owner’s arguments are directed toward an embodiment of Isaksson that Petitioner did not cite in its Petition. Pet. Reply 26. In any case, Patent Owner does not establish that using Isaksson’s base sync messages in Kliger’s system would have been beyond a POSITA’s skill. Id. at 25–26 (citing Ex. 1036 ¶¶ 90– 93). Patent Owner argues that Isaksson’s base sync frames would alter the principle of operation of Kliger because Kliger requires all devices to transmit fixed constellation size based on overall network characteristics rather than specific channel characteristics between each HNM. PO Resp. 60–63 (citing Ex. 1007, code (57), ¶¶ 40–44, 91, 99, Fig. 1; Ex. 1013, 3:24– 27, 20:24–25, 26:14–17, 78:5–79:5, Fig. 36; Ex. 2002 ¶¶ 155–157). Patent Owner has not established, however, that fixed constellation size is a “principle of operation” of Kliger, or that Kliger would require substantial reconstruction or redesign to incorporate variable constellation sizes. See In re Ratti, 270 F.2d 810, 813 (CCPA 1959). We agree with Dr. Williams that a POSITA would have sought to improve Kliger with Isaksson’s techniques. Ex. 1036 ¶ 95.” slip op. at 19

“Kliger and Isaksson are analogous art to the ’518 patent because they are from the same field of endeavor as the patent—wired networking systems— and because they are reasonably pertinent to the problem at issue in the patent—overcoming wired-network signal impairments.” Pet. 27 (citing Ex. 1004 ¶¶ 76–80); Pet.

“Considering the parties’ proposals and the record evidence, we adopt the following level of ordinary skill in the art, which we apply in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to three years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” too narrow. Although Patent Owner points to various parts of the ’249 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 LAN wiring, twisted pair, and satellite as communications media that can be used. See, e.g., Ex. 1001, 1:11–16, 2:65–66, 3:9–37, 3:58–61, 7:4–5. In addition, while Patent Owner indicates that the ’249 patent addresses “the problem of tap port-to-port isolation and providing a suitable signal path for terminal-to-terminal communication in a coaxial cable wired building” (id. at 3:4–7), we see no reason why this problem and the solutions proposed in the ’249 patent (using frequency bins to bit load or equalization) would not be equally applicable to other kinds of communication media. Therefore, we find our adopted skill level to be consistent with the problems and solutions identified in the ’249 patent and 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. Ex. 1002 ¶¶ 17–18; Ex. 2007 ¶¶ 57–58.” slip op. at 14

“On this record, we find that Petitioner has shown by a preponderance of the evidence that Jacobsen was publicly accessible more than one year before the ’249 patent. Jacobsen is thus § 102(b) prior art. By its own terms, Jacobsen indicates that it is one of the National Cable Television Association (“NCTA”) 1994 Technical Papers related to the 43rd Annual NCTA Convention and Exposition, New Orleans, Louisiana, May 22–25, 1994. Ex. 1007, 1–3, 6. This event and related papers address topics that would have interested persons in the field as we define their skill level. See § II.B, supra. The listing of Jacobsen as one of the papers covered in the event schedule suggests that POSITAs attending this event would have known of and had access to Jacobsen. Ex. 1007, 2–3. In fact, Mr. Bates, Patent Owner’s own expert witness, who was at least a person having ordinary skill in the art, testified that he was aware of Dr. Jacobsen’s work in the late 1990s, well before the priority date. See Ex. 1029, 52:10– 55:1. Therefore, a person having ordinary skill in the art would have known of Jacobsen before the priority date. See Nobel Biocare Servs. AG v. Instradent USA, Inc., 903 F.3d 1365 (Fed. Cir. 2018) (holding that a catalog distributed at a conference was a printed publication); In re Klopfenstein, 380 F.3d 1345 (Fed. Cir. 2004) (holding a slide presentation at a conference was a printed publication); Mass. Inst. of Tech. v. AB Fortia, 774, F.2d 1104 (Fed. Cir. 1985) (holding that a paper disseminated to six people of ordinary skill in the art and discussed with between 50 and 500 people skilled in the art was a printed publication). The evidence further demonstrates that Jacobsen was acquired by the Linda Hall Library, Kansas City, Missouri, on September 19, 1995 and made available to the public shortly afterward. Ex. 1022 ¶¶ 4–5, 13; Ex. 1031 ¶¶ 7, 17. Availability to interested persons more than one year before the ’249 patent is corroborated by other publications of Jacobsen, as well as Dr. Acton’s testimony. Ex. 1022 ¶¶ 10–13; Ex. 1031 ¶¶ 10–12, 16–17; Ex. 1003 ¶ 247. We do not agree with Patent Owner’s arguments against Jacobsen. There is no requirement in the law for Ms. Munford to be an interested person or POSITA in order for her to testify about how the Linda Hall Library acquired and cataloged Jacobsen so that interested persons would be able to access it. Her testimony relates to the public accessibility of Jacobsen, not its technical content. See, e.g., Ex. 1031 ¶ 6. She need not qualify as a POSITA to offer this testimony.

“We do not agree with Patent Owner that Amit is restricted to “single frequency” modulation. PO Resp. 52–56. As Petitioner notes, Amit describes that its HCNM modem uses a channel (e.g., DOCSIS) containing two sub-channels for upstream and downstream signals. Pet. 24 (citing Ex. 1005, 15:18–28). This meets Patent Owner’s definition for multicarrier communications as multiple subcarriers to provide communications of a single channel. PO Sur-Reply 6. We further note that the claims do not recite “multicarrier communications” so the distinction Patent Owner attempts to draw is not supported by commensurate language in the claims. See In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (limitations not appearing in a claim cannot be relied upon for patentability). Furthermore, even if Amit were restricted to single carrier modulation, as Patent Owner argues, Petitioner relies on Jacobsen for its teaching of multicarrier modulation. Pet. 62–66; PO Resp. 52–56.

“Considering the parties’ proposals and the record evidence, we adopt the following level of ordinary skill in the art, which we apply in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to three years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” too narrow. Although Patent Owner points to various parts of the ’249 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 LAN wiring, twisted pair, and satellite as communications media that can be used. See, e.g., Ex. 1001, 1:11–16, 2:65–66, 3:9–37, 3:58–61, 7:4–5. In addition, while Patent Owner indicates that the ’249 patent addresses “the problem of tap port-to-port isolation and providing a suitable signal path for terminal-to-terminal communication in a coaxial cable wired building” (id. at 3:4–7), we see no reason why this problem and the solutions proposed in the ’249 patent (using frequency bins to bit load or equalization) would not be equally applicable to other kinds of communication media.

“After review of the ’404 patent’s description, we find no disclosure that pressing the panic button together with another button causes the panic button to ready itself to perform functions (1) and (2) as recited in limitation 1[d]. The closest descriptions we find to limitation 1[d] are that the safety switch readies the panic button to contact 911 (Ex. 1001, 6:59–62), that the panic button may be activated by pressing the panic button with another button (id., 3:59–67, and that the panic button may start a speech recognition process that can trigger the device (id., 7:61–62). Consequently, claim 1 is itself the best source for determining what the claim language means. We determine that the ordinary and customary meaning of the “ready itself” feature of claim 1 is that the panic button “prepares itself to be triggered to perform the panic button functions (1) and (2).” Since the intrinsic evidence is sufficiently clear to discern the meaning of the “ready itself” limitation, we do not resort to extrinsic evidence. See Phillips, 415 F.3d at 1317 (explaining that extrinsic evidence is less significant than intrinsic evidence); Seabed Geosolutions (US) Inc. v. Magseis FF LLC, 8 F.4th 1285, 1287 (Fed.

“Thus, the ’353 application describes that moving the safety switch into position readies the panic button to contact 911, which is not the same as the panic button being activated to ready itself to perform functions (1) and (2) required by claim 1 of the ’404 patent. Patent Owner’s reliance on disclosures elsewhere in the ’353 application is unavailing. PO Resp. 5–8 (citing Ex. 1006, 15, 17, 19–21, 23, 25); PO Sur-Reply 2–3 (citing Ex. 1006, 15, 17, 19–20, 24–25)). For example, while the ’353 application does mention voice activation with a codeword and activation by depressing of the panic button together with another button (see, e.g., Ex. 1006, 17, 21, 24–25), it does not mention that depressing the panic button together with another button causes the panic button to ready itself to perform recited functions (1) and (2). The application explains that “[t]he [panic] button can send a signal to a controller inside the device to activate [the code word activation] process” and “[t]he [panic] button can start the speech recognition process in one embodiment, to trigger the device.” Ex. 1006, 25. But that describes readying the device for activation by the code word, not readying the button to perform the recited functions. The ’353 application also mentions the word “ready” in relation to using a self-defense mechanism such as pepper spray, which does not appear to be related the readying of the panic button recited in claim 1. Ex. 1006, 15, 19–20. Petitioner has thus met its burden to demonstrate that claims 1–8 of the ’404 patent lack written description support for a panic button adapted to “ready itself” to perform the recited functions because the limitation is not present in the ’353 application to which the ’404 patent claims priority.3 Pet. 8–10.

“DiPerna964 discloses a separate “safety” switch that readies the panic button to contact 911 upon being pressed (Ex. 1028 ¶ 41), but there is no mention of pressing the panic button together with another button to cause the panic button to “ready itself” to perform panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit, as limitations 1[d] and 1[e] require. DiPerna964 mentions pressing two buttons together to activate the panic button (see, e.g., Ex. 1028 ¶¶ 17, 23–25, 27), but not to “ready itself” to perform recited functions (1) and (2). Petitioner relies on Strack’s triggering the collection of audio, video, and location data for transmission to a remote location as equivalent to a panic button readying itself to, when activated, perform the panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit. Pet. 15–17 (citing Ex. 1002 ¶¶ 76–88). We do not agree with Petitioner’s contention because Petitioner fails to explain how Strack’s button press that collects and then transmits audio, video, and location data would ready the panic button to perform recited functions (1) and (2). It appears that Strack’s button press readies the device, not the button, to perform the functions.

“enablement for Alden’s system detecting road curves. Pet. Reply 21. As Petitioner points out, Alden uses both intensity and a detected object’s location (including distance) to inform its response. Ex. 1005 ¶¶ 27–28. Petitioner’s expert testifies that the same physical system used to accommodate oncoming vehicles could be used to detect roadside reflectors and direct light into road curves. Ex. 2041, 78:16–80:24. Further, Petitioner’s expert testifies that skilled artisans would adjust the intensity and distance thresholds to distinguish roadside reflectors from oncoming vehicles. IPR2023-01039, Ex. 1003 ¶ 150. Based on Alden’s disclosures, we credit Petitioner’s expert’s testimony that Alden’s system would detect and accommodate road curvatures as claimed by the ’551 patent. Ex. 1003 ¶¶ 132–134. Although Patent Owner argues that Alden’s system could not do so while also accommodating oncoming vehicles, that position is based on the argument that “the system can’t tell the difference between signs and headlights.” PO Surreply 21–23. Patent Owner contends that “detected intensity is a function of both distance and emission intensity” so a threshold couldn’t distinguish headlights from signs. Id. at 24–25. That position ignores that Alden uses triangulation to calculate each object’s distance, as discussed, which would allow it to distinguish different types of objects using an intensity threshold. We agree with Petitioner’s expert that Alden’s system can distinguish the two, as discussed.” slip op. at 33

“sufficiently clear to impart a requirement on “classifying” such that a system must choose from multiple classes or types of objects.

“We agree with Petitioner. Alden’s system does not simply dim its headlights where it detects spots of light. Rather, it performs a multistep process in which those spots are detected, analyzed with triangulation to determine distance, and then used to determine dimming zones. Ex. 1005 ¶¶ 27–28. Alden discloses that its sensor “detects the two headlights” of an oncoming vehicle when “[e]lectrons corresponding to the position and intensity of light are categorized by a logic and CPU 71 and stored in a memory 72.” Id. ¶ 27. Petitioner’s expert noted that Alden’s description “move[s] from lights – thresholding lights to objects, and then calculate[s] distance of each thresholding object using triangulation.” Ex. 2041, 109:23–110:2. That testimony supports our view that Alden first detects lights, uses those detected lights to identify and classify an oncoming car, then dims the headlight output to prevent glare. Alden’s dimming decision particularly indicates that it classifies pairs of detected headlights as oncoming vehicles. The CPU makes “assumptions about the space that may potentially be occupied by the driver of the sensed vehicle” and identifies an area of the segmented headlight to dim that is “significantly larger than the headlight dots that were initially received.” Ex. 1005 ¶ 27. Patent Owner agrees that Alden dims “selected surrounding sectors” around detected light (PO Resp. 30), and the way Alden selects those sectors indicates that it identifies vehicles. It does not simply expand an area around each detected light; it dims an area to encompass the driver of the identified vehicle. Ex. 1005 ¶ 27, Fig. 3. By treating a pair of corresponding detected lights collectively for dimming, Alden indicates that it classifies pairs of detected lights as vehicles.” slip op. at 23

“The problem with Patent Owner’s claim-construction position is that neither the dictionary definition nor the ’551 patent’s specification establish any degree of proof, verification, or confirmation that an object has been correctly identified. The specification discloses that “techniques known in the art” may be used “to classify, identify or locate the contents” visible to a camera sensor. Ex. 1001, 44:67–45:9. That does not establish any certainty obtained by the preexisting techniques. The specification states that the system can “illuminate distant overhead and roadside signs” and can use “[i]mage recognition via a camera” so that the illumination beam may “follow the retroreflective sign as the vehicle moves.” Id. at 51:59–67. That disclosure does not speak to any degree of confirmation or certainty. The specification’s other disclosures are no different. Id. at 52:19–27 (disclosing automated control over lighting and referencing “automatic dimming of high beam due to detection of oncoming vehicles”), 52:66–53:4 (“Using color and pattern recognition techniques it is possible to determine what is a sign.”), 63:9–12 (“Using real time image processing methodologies with image and scene recognition technology known in the art, room or outdoor area elements, objects and people are identified.”), 64:46–49 (“Using machine vision technology known in the art such as neural networks training and other pattern recognition techniques the vision system has sensor, algorithmic and computation means for identifying devices or objects.”), 69:54–57 (“In a preferred embodiment of the invention the logical controller 454 receiving image input from the camera 453 and running pattern recognition software will identify what is the visual task a person is trying to perform.”), 75:48–62 (“Using programmed scene recognition algorithms, the luminaire’s computer vision system comprised of the camera sensor 496 and logical controller 494 identifies the food on the plate, looks-up in storage the recommended CCT and powers each of the different colored LED chips aimed thereon at the correct power level in order to provide the optimal color illumination.”), 76:33–39 (“[A] camera vision system has algorithmic means to identify and track the position of people and objects and the logical controller has motion control means for re-aiming the light sources towards targeted elements and changing the power level to the LED chips.”). None of those disclosures addresses a requirement for confirming or verifying an identification that the system makes; nor does any address a particular accuracy requirement in identifying an object. Based on the specification using “identify” without any requirement that identifying an object requires confirmation or verification of the object’s true identify, we do not adopt Patent Owner’s proposed construction. Although the construction itself similarly does not expressly require the confirmation or verification that Patent Owner seeks to impose, we understand that to be Patent Owner’s intent, and accordingly do not adopt the proposed construction. The parties dispute no other aspect of “identify,” and we therefore need not expressly construe the term.” slip op. at 9

“Because Alden describes its segmented headlights as implementing a process using two-dimensional signals for two-dimensional dimming functionality, we find that Figure 5 depicts a section of an embodiment that contains more than a single row of lighting elements. Stated otherwise, Alden’s disclosures are consistent with each other and are directed to a two-dimensional approach to sensing, control, and illumination. Further, we agree with Petitioner that Patent Owner has not addressed the legal standard for lack of enablement. Pet. Reply 2. In particular, to overcome the presumption that prior-art disclosures are enabled, Patent Owner must show ordinarily skilled artisans would require undue experimentation to practice the disclosed invention. See Amgen Inc. v. Hoechst Marion Roussel, Inc., 314 F. 3d 1313, 1354–55 (Fed. Cir. 2003); In re Antor Media Corp., 689 F. 3d 1282, 1287– 88 (Fed. Cir. 2012). We do not agree with Patent Owner that Alden lacks a presumption of enablement (see PO Surreply 7–8), because we determine that Petitioner’s contentions rely on Alden’s disclosures regarding its invention as a whole. Other than arguing that Figure 5 discloses a single-row embodiment that is unusable with Alden’s other disclosures, Patent Owner has made no attempt to show Alden lacks enablement. Patent Owner has not addressed what experimentation skilled artisans would require to practice an invention using Alden’s Figure 5 segmented headlight with the remainder of Alden’s system as disclosed in Figures 2, 3, and 4, and Alden’s corresponding textual description. We therefore determine that Patent Owner has not shown Alden to lack enablement for its disclosed invention.” slip op. at 20

“Petitioner asserts that skilled artisans would have had reason to incorporate Kobayashi’s teachings that its controller receives “road map information” from a “road profile calculating means” and uses it to adjust the headlamp’s illumination. Pet. 63–64. Petitioner reasons that it would be obvious to “apply these teachings to Alden to use map data to identify road curvature when adapting the LEDs of Alden to ‘direct light into the corner.’” Id. at 64 (citing Ex. 1003 ¶ 122). And Petitioner asserts that skilled artisans had reason to do so because it would “maximize successful detection in different environments” such as where the road lack reflectors. Id. at 65 (citing Ex. 1003 ¶ 123). Other than as discussed above regarding Alden’s disclosures, Patent Owner does not contest Petitioner’s showing for claims 28, 36, and 44. We have considered the full record, including evidence and arguments presented by Petitioner and Patent Owner on whether the combination of Alden and Kobayashi discloses each limitation of claims 28, 36, and 44, and whether skilled artisans would have had reason to combine the references’ teachings as asserted. Based on the full record, we conclude that Petitioner has proven that claims 28, 36, and 44 would have been obvious over Alden and Kobayashi. Pet. 62–65.” slip op. at 34
