    “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.

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.

    “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

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.

    “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.

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.

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.

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.

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.

    “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.

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

    “3. The Alleged Anticipation of Claim 1 a. A portable interrogator, comprising: Petitioner contends that the preamble is not limiting, but, to the extent that it is, Garber discloses a portable interrogator. Pet. 12–13 (citing, inter alia, Ex. 1005, 14:59–62, 15:63–65). Petitioner asserts that Garber discloses a portable interrogator in the form of a hand-held RFID device, and points to, inter alia, Garber’s description of Figure 4 as depicting “a block diagram of an RFID interrogation system interacting with an RFID tag.” Id. at 12 (quoting Ex. 1005, 3:46–47) (emphasis omitted). Patent Owner does not raise any arguments regarding this contention. b. an antenna configured to receive a first signal from a first object; Petitioner contends that Garber discloses a hand-held RFID device having an antenna for the RFID reader. Pet. 13–14 (citing Ex. 1005, 15:43– 46, 16:11–13, Fig. 13; Ex. 1002 ¶¶ 75–78). Petitioner further contends that Garber’s Figure 13 depicts the antenna receiving an RFID signal from a tag attached to a library book. Id. at 13. Petitioner additionally contends that Garber discloses the identification, by the RFID device, of multiple items via code signals 202, thus disclosing an antenna configured to receive a first signal from a first object. Id. at 14. Petitioner notes that Garber states, “[t]he hand-held RFID device . . . is capable of identifying multiple items that are within the range of the device.” Id. (quoting Ex. 1005, 14:40–45) (emphasis and alterations in original). Petitioner further asserts that “Garber also teaches that ‘if items used in the library are first placed on a book cart [in close proximity without obstructions], for example, the hand-held device could make a single pass by the items on the cart to record them.’” Id. (quoting Ex. 1005, 18:25–27) (emphasis and alterations in original). Patent Owner does not raise any arguments regarding these contentions. c. a control and processing subsystem configured to discern a presence of said first object from said first signal; and Petitioner contends that: Garber discloses a control and processing subsystem (e.g., the processor in the hand-held RFID device/computer 108) configured to discern a presence of (e.g., decoding response from tags to identify tagged item) said first object (e.g., the RFID tags) from said first signal (e.g., signals produced by tags/response code signal 202).

    “4. Motivation to Combine Garber and Andersen Relying on the testimony of Dr. Sharony, Petitioner argues that one of ordinary skill would have been motivated to combine Garber and Andersen for several reasons. Pet. 49, 52 (citing Ex. 1002 ¶¶ 187–196). First, Petitioner argues that Garber and Andersen are analogous art to the ’293 patent “because they are in the same field of endeavor—namely, interrogation systems.” Id. at 49. Specifically, Petitioner argues that Garber and Andersen are analogous to the ’293 patent “because they are reasonably pertinent to the technical problem allegedly addressed by the claimed invention.” Id. Petitioner contends that “[t]he ’293 Patent identifies deficiencies in the prior art as including [inter alia] a requirement ‘that each device be interrogated separately’ (versus ‘[t]he ability to interrogate a plurality of closely spaced tags simultaneously’).” Id. at 49–50 (citing Ex. 1001, 4:16–25, 5:56–6:15, 6:40–46) (third alteration in original). According to Petitioner, Garber discloses, among other things, that “‘[a]nother benefit’ of the RFID device as ‘the ability to process multiple items at one time’ where ‘conventional devices having only optical bar code scanners can process only a single item . . . at one time.’” Id. at 50 (citing Ex. 1005, 13:25–30, 13:30–36 (“greatly reduc[ing] the time required for library staff to process multiple items.”)) (alterations in original). Petitioner argues that “Andersen is also analogous because it teaches ‘a system for tracking inventory having RFID components” and is designed to remedy the deficiencies of prior art inventory tracking systems using bar codes, which can be torn, destroyed, or hidden from view. Id. at 50–51 (citing Ex. 1007, 1:8–10, 1:58–2:2, 2:4–5). Additionally, according to Petitioner, Andersen is intended to address multipath errors and teaches that one way to refine radio signals received by RFID tags is by using a Kalman filter. Id. at 51 (citing Ex. 1007, 11:25–28, 11:32–36). Petitioner also argus that Andersen “provides ample motivation to add a Kalman filter to Garber’s hand-held device” to provide “correction of multi scanned signal / multipath errors.” Pet. 51 (citing Ex. 1007, 11:25–28, 11:32–36, 12:39–41). “As such,” Petitioner asserts, one of ordinary skill would have found it obvious “to modify Garber’s handheld device, which is used inside a library where shelves and other obstacles can result in multipath errors, to use Andersen’s Kalman filter to address these errors.” Id. Additionally, according to Petitioner, one of ordinary skill “could have combined Andersen’s Kalman Filter with Garber’s hand-held device using known methods, and such a filter would merely perform the same function—resolving errors to improve detection accuracy, which is entirely predictable.” Id. at 51–52. Finally, Petitioner contends, one of ordinary skill would have had a reasonable expectation of success in making the proposed combination because “[t]he interrogator components described in Garber and Andersen were well-known at the time,” and the modification of Garber’s interrogator to include Andersen’s Kalman filter would have been straightforward for a person of ordinary skill. Id. at 52. Patent Owner responds that Petitioner’s motivation to combine Garber and Andersen is insufficient. PO Resp. 29–32; PO Sur-reply 23. First, Patent Owner argues that the combination is based on impermissible hindsight because Petitioner did not explain why one of ordinary skill would have combined Garber and Andersen “to teach a control and processing unit employing an adaptive integrated filter or multiscan, coherent signal processing.” PO Resp. 31. According to Patent Owner, one of ordinary skill would not have been motivated to combine Garber and Andersen because “Andersen teaches the use of filters to correct multipath signal errors arising from the transmission of a single signal,” while the ’293 patent “teaches the use of filters to process multiple diverse inputs with a signal representing an RFID object to discern the presence of that object and teaches multiscan, coherent signal processing to coordinate the processing of a plurality of signals.” Id. “In either case,” Patent Owner contends, “the problems solved by the ’293 Patent involve multiple signals and not the single signal problem addressed by Andersen.” Id.” slip op. at 68

    “5. Objective Indicia of Non-Obviousness Patent Owner asserts that there is evidence of long felt but unresolved need that constitutes objective indicia of nonobviousness. PO Resp. 32–33; see PO Sur-reply 24 (“others in the field had attempted and failed to solve the problems addressed by the ‘293 Patent”). Patent Owner also makes certain assertions regarding the adoption and possible acquisition of its technology. PO Resp. 34; see also PO Sur-reply 24 (referring to “industry acceptance of Lone Star’s inventions”). Petitioner characterizes these latter assertions as allegations of industry praise and commercial success. Pet. Reply 24. In support of its objective indicia arguments, Patent Owner relies solely on the declaration of named-inventor John Volpi (Ex. 2018). See PO Resp. 32. Petitioner argues that there is no nexus to the claimed invention because Patent Owner “has not identified the merits of the claimed invention or any product that embodies the claimed features or is coextensive with them.” Pet. Reply 23–24. Petitioner also argues that Patent Owner “has not established industry praise or commercial success, let alone a nexus to the merits of the claimed invention.” Id. at 24. As the Federal Circuit has explained: For objective evidence of secondary considerations to be relevant, there must be a nexus between the merits of the claimed invention and the objective evidence. See In re GPAC, 57 F.3d 1573, 1580 (Fed. Cir. 1995). A showing of nexus can be made in two ways: (1) via a presumption of nexus, or (2) via a showing that the evidence is a direct result of the unique characteristics of the claimed invention. A patent owner is entitled to a presumption of nexus when it shows that the asserted objective evidence is tied to a specific product that “embodies the claimed features, and is coextensive with them.” Brown & Williamson Tobacco Corp. v. Philip Morris, Inc., 229 F.3d 1120, 1130 (Fed. Cir. 2000). . . . However, even absent a presumption of nexus, “the patent owner is still afforded an opportunity to prove nexus by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373–74 (Fed. Cir. 2019) (quoting In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996)).” slip op. at 72
