    “We do not agree with Patent Owner that Petitioner’s showing uses the same sound data to teach the “first sound data” of limitation 1.a and the “second sound data” of limitation 1.c. Patent Owner is correct that Rosenberg’s claim 5 describes the determination of a volume threshold based on the volume of the ambient audio signal in which characteristic form(s) (e.g., the name of the user of the media player) are present. Ex. 1006, 13:66–21, 14:28–30. However, the Petition describes using Fu’s “predetermined threshold” in combination with Hart-787’s device, which attenuates audio output of a device upon detecting a user’s utterance intended to gain the attention of the device, in order to “include adjusting the audio output volume of a wirelessly-linked audio-producing device when the voice-controlled device determines that the ambient noise level at the time a Ex. 1004, 2:22–37, 5:61–6:10, 9:18–25; Ex. 1005 ¶¶ 24, 32, 54; Ex. 1003 ¶¶ 88–89). Petitioner further proposes including a threshold that is advantageously based on the environment in which the device is operating as described in Fu, for example to respond to differing levels of noise at different times of day. Id. at 26, 29–30, 40 (citing Ex. 1006, 10:42–67, 14:28–30; Ex. 1003 ¶¶ 48–53, 55, 58, 87, 91, 107–109). We agree with Petitioner that Patent Owner’s arguments address the references individually instead of addressing the combination of the teachings proposed in the Petition. See Pet. Reply 8, 13–14; see also Dec. on Inst. 21–22, 23–24, 25–26. The Petition relies upon a combination of elements of Hart-787 with the predetermined threshold as taught in Fu and with establishing such a threshold based on the operating environment of a device as in Rosenberg. Pet. 26–31, 34–41. Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition. We also find that the preponderance of the evidence supports Petitioner’s showing regarding the motivation to combine the references.” slip op. at 23

We conclude Petitioner’s evidence regarding the showing in Hart-787 is sufficient with respect to this point. Hart-787 describes altering a signal sent to the speaker to attenuate the audio from that speaker. Ex. 1004, 1:67– 2:1.

    “construction against the prior art than it does to construction of the term itself. Patent Owner’s proposed construction, like Petitioner’s, does not, on its face, exclude RF protocol conversion. In this respect, we agree with Petitioner that Patent Owner is improperly attempting to read in additional limitations that go beyond claim 5’s broad recitation of a “transmitter . . . configured to encode the electrical signal.” See Paper 45, 3. As Petitioner further observes, the Specification of the ’661 patent refers interchangeably to data controller 324 (shown in Figures 3A–3E, not reproduced here) as “data formatter 324” (emphasis added), which “operates to form concise data packets.” Id.; Ex. 1001, col. 8, ll. 49–51. Petitioner’s proposed construction is thus consistent with the Specification. Patent Owner agrees that data controller 324 “encodes a physical condition into a function code,” but emphasizes that it does so “before getting converted by the RF transmitter.” Paper 44, 3. The distinction Patent Owner relies on to exclude RF protocol conversion from its proposed construction would improperly narrow the scope of the claim by implicitly adding a limitation that has no express basis in the claim. In re Prater, 415 F.2d 1393, 1404–05 (CCPA 1969) (“Nevertheless, ‘reading a claim in the light of the specification,’ to thereby interpret limitations explicitly recited in the claim, is a quite different thing from ‘reading limitations of the specification into a claim,’ to thereby narrow the scope of the claim by implicitly adding disclosed limitations which have no express basis in the claim.”). Having thus considered the parties’ positions, we adopt Petitioner’s proposed construction of “encoded electrical signal” as “coded information representing the electrical signal generated by the sensor.” We address application of this construction to the prior art in the analysis below.” slip op. at 12

  • Skill levelSkill level patent owner adoptedDecided for patent owner

    “Patent Owner does not advocate for a specific level of skill in its Response, but its expert, Kevin C. Almeroth, Ph.D., articulates a level of skill similar to Petitioner’s proposal. Ex. 2009 ¶ 75. Specifically, Dr. Almeroth opines that a person of ordinary skill “would have the equivalent of a four-year degree from an accredited institution (usually denoted as a B.S. degree) in computer science, computer engineering or the equivalent and experience with, or exposure to, computer networks and routing.” Id. In addition, according to Dr. Almeroth, a person of ordinary skill “would also have approximately two years of professional experience with computer networking, routing, and wireless networks. Id. And “[a]dditional graduate education could substitute for professional experience, while significant experience in the field might substitute for formal education.” Id. Given the similarity of articulations by the respective experts, and because our Decision does not depend on nuanced distinctions of the level of skill in the art, we adopt Dr. Almeroth’s more detailed articulation, but include electrical engineering as an additional alternative educational background, as indicated by Mr. Kinney.” slip op. at 15

    “We thus agree with Patent Owner that the rationale articulated by Petitioner is conclusory, and insufficiently supported. PO Resp. 30–31. On the record before us, it is more reasonable to construe “the transceiver identification information” as referring to something other than the identification information for the at least one wireless transmitter. For example, Patent Owner contends that “[o]ne skilled in the art, reading the plain text of claims 5 and 8, would easily recognize that the ‘transceiver’ referred to in claim 8 is the transmitter in claim 5 that is configured to both send and receive signals.” Id. at 33. Patent Owner provides support for this reading both by identifying disclosure in the Specification of the ’661 patent consistent with its position, and through testimony by its expert, Dr. Almeroth. Id. at 33–36 (citing Ex. 1001, Figs. 2, 3C, 3D, col. 6, ll. 3–8, col. 9, ll. 53–56, col. 10, ll. 32–34; Ex. 2009 ¶¶ 125–132). For example, Dr. Almeroth testifies that Mason’s AMR server “at most would need only some meter identification number and a meter reading.” Ex. 2009 ¶ 134. We credit this testimony, as well as Dr. Almeroth’s assertion that “[t]ransceiver identification information is extraneous for the needs of the AMR server in Cunningham and Mason.” Id. Ultimately, we need not resolve the construction issues, and the issue of whether claim 8 is indefinite is not before us. 35 U.S.C. § 311(b) (limiting inter partes review to “a ground that could be raised under section 102 or 103”). It is sufficient for us to determine whether Petitioner has put forth sufficient evidence to meet its burden of establishing that claim 8 would have been obvious over the combination of Mason, Shuey, and Cunningham. In light of the foregoing considerations, we conclude that Petitioner has not.” slip op. at 34

    “c. “one or more additional wireless transmitters” Third, Petitioner combines the teachings of Shuey with those of Mason in addressing claim 5’s recitation of “one or more additional wireless transmitters.” Id. at 62–63. The claim requires that each such additional wireless transmitter is “electrically interfaced with a sensor and configured to receive the RF signal and retransmit the RF signal,” i.e., to act as a repeater. Ex. 1001, col. 19, ll. 22–24. As discussed above, Mason discloses that meter 12D is considered “inaccessible” with respect to node 18, and that another meter within the network may act as a repeater so that the inaccessible meter may still be contacted. Id. at col. 6, ll. 27–35. Petitioner cites Shuey for details regarding the information included in retransmission by meters acting as repeaters, and provides sufficient reason to effect the combination in light of Mason’s explicit reference to Shuey: “A POSITA would have been motivated to incorporate into Mason’s system Shuey’s teaching of a repeater that retransmits all of the claimed information, because Mason explicitly notes that Shuey’s system is a system for which Mason’s invention is particularly suited.” Pet. 58–59 (citing Ex. 1007, col. 6, ll. 35–38; Ex. 1002 ¶¶ 110–112).

    “as disclosed by Gerten’s description of modified frequency hopping schemes. Id. at 14. In doing so, Petitioner notes that Gerten discloses periodic updating of the modified frequency hopping scheme, supporting a conclusion that Gerten discloses selection at different times. Id. at 14, 15– 16. Petitioner highlights this periodic updating to identify distinct “period[s] of time” during which different “set[s] of two or more communications channels [are] used to transmit and receive.” Id. at 15–16 (italics omitted). In addressing independent claim 1’s specific requirement that different sets of channels be used with the second and third communications devices, Petitioner reasons that the process summarized above may be applied by the master device to each of the slave devices separately: “the master device of Gerten performs a service discovery request to determine if each slave device has interference avoidance capabilities.” Id. at 18 (emphasis added) (citing Ding Decl. ¶ 53; Ex. 1003, col. 4, ll. 38–51). Thus, Petitioner argues, if one slave has such interference avoidance capabilities, communications with that slave may take place using a modified frequency hopping scheme; if another (legacy) slave lacks such interference avoidance capabilities, communications take place using a normal mode with default communications channels that are not changed based on channel performance. Id. at 18 (citing Ding Decl. ¶ 55); see id. at 16–17. Thus, Petitioner concludes, the recited transmissions and receptions from the third communications device over default communications channels occur “while” transmitting to and receiving from the second communications device over the first and second sets of communications channels, as we have construed the term “while.” Petitioner supports this reasoning with testimony by Dr. Ding, which we credit.

If the assertion that Favrat is prior art under § 102(a) was required to be in the Petition, then the fact that the issue was raised in Patent Owner’s Response does not cure that oversight. As the Federal Circuit recently emphasized, It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify “with particularity” the “evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3).

Prior to filing of the instant Petition, Petitioner knew from Patent Owner’s contentions in the ITC proceeding that the safe haven of § 103(c) was a potential issue. See Ex. 1207, 3. Even armed with this knowledge, Petitioner chose not to assert in the Petition that Favrat is prior art under § 102(a).

Petitioner’s reply, however, fails to recognize that Petitioner bears the burden of demonstrating that Mullin anticipates the claim, including providing sufficient evidence and argument in support of its proposed claim interpretation. The Petition fails to provide a sufficient explanation to support that “when both” should be construed in the manner asserted by Petitioner, particularly when the more natural reading of the claim language conveys that two sensing circuits sense power at the same time. Although Petitioner provided a second declaration from Mr. McAlexander in reply to Patent Owner’s response, neither that declaration nor Mr. McAlexander’s first declaration provides sufficient support for how claim 2 would have been understood by a person of ordinary skill to show that it is anticipated by Mullin. See Exs. 1007 and 1011.

    “Mot. 15. Patent Owner’s attorney argument, which cites no evidence, does not support the contention that the proposed amended claim would not have been obvious to a person of ordinary skill in the art. Nonobviousness cannot be established by attacking the references individually when unpatentability is predicated upon a combination of prior art disclosures. See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986). Even if each prior art reference is “missing at least two of the required limitations,” that has limited bearing on whether a combination of those references renders the claim obvious. Similarly, Patent Owner provides insufficient support for its implicit argument that one would not combine the references because, individually, they provide a “complete solution” to the problem they intend to address. Where “a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 416 (2007). Thus, Patent Owner’s suggestion that there “is no reason one of skill would engage in mixing and matching,” fails to adequately address whether the combination would have been obvious.

    “We agree with Petitioner that, for Mullin to anticipate claim 1, Mullin need not disclose power sensed at COM. See Pet. Reply 19–22. The claim language does not require power to be sensed at any specific location, only that one sensing circuit senses “power applied to” the first and second inputs, and the other senses “power applied to” the second and third inputs. Patent Owner does not direct us to any persuasive disclosure in the ’459 patent to support its contention that claim 1 requires that power be sensed at the second input. See PO Resp. 21–26. Similarly, although Dr. Horenstein states that “the Mullin circuit is incapable of providing unique information that power has been connected to COM,” a point not in dispute, Dr. Horenstein provides only conclusory assertions and no persuasive explanation for why claim 1 would be understood to require such “unique information” for the second input. See Ex. 2001 ¶¶ 56, 63. Moreover, in Mullin, when a sensor detects power at either P2 or P3, power is necessarily applied to COM (neutral) to complete the circuit, even if the sensor does not directly detect power at COM. As Dr. Horenstein explained, “at least two inputs from the source of AC power – generally line and neutral – would have to be connected in order to complete the circuit and enable the flow of power to the motor.” Ex. 2001 ¶ 53. Mr. McAlexander similarly explained that by the very nature of alternating current, “the flow of electric charge periodically reverses direction.” Ex. 1011 ¶ 12. Thus, when alternating current is applied to Mullin’s input P2 and COM it will “be input from the input P2 and return by way of the COM, and at other times it will be input from the COM and return by way of the input P2.” Id. ¶ 13. The same is true of P3 and COM. See id. As shown by Petitioner, Dr. Horenstein confirmed during cross-examination that, when AC power, as referred to in Mullin, is applied to the power input P2 and common input COM as shown above, the opto-isolator ISO1 senses this power and outputs a corresponding signal, [and] when Mullin’s AC power is applied to the power input P3 and common input COM as shown above, the opto-isolator ISO2 senses this power and outputs a corresponding signal. Pet. Reply 22; see also Ex. 1010, 68:24–69:19. Accordingly, the testimony of Mr. McAlexander and Dr. Horenstein supports our determination that Mullin discloses a first sensing circuits that “senses power applied to the first and second inputs” and a second sensing circuit that “senses power applied to the second and third inputs,” as well as a motor controller that is “operable for determining that power is applied to the first input when the first sensing circuit senses power,” as required by claim 1.” slip op. at 11

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “Ex. 2001 ¶¶ 104–105. Thus, Dr. Horenstein contends there is a lack of a motivation to combine the references because opto-couplers are simpler and require fewer parts than the current based sensor of Nordby. In KSR, the Supreme Court rejected the Federal Circuit’s rigid application of its “teaching, suggestion, motivation” test in favor of an expansive and flexible approach. 550 U.S. at 415. The Supreme Court noted that often, it will be necessary: to look to interrelated teachings of multiple patents; the effects of demands known to the design community or present in the marketplace; and the background knowledge possessed by a person having ordinary skill in the art, all in order to determine whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue. Id. at 418. Moreover, the Federal Circuit has explained that: an implicit motivation to combine exists not only when a suggestion may be gleaned from the prior art as a whole, but when the “improvement” is technology-independent and the combination of references results in a product or process that is more desirable for example because it is stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient. Because the desire to enhance commercial opportunities by improving a product or process is universal – and even common-sensical – we have held that there exists in these situations a motivation to combine prior art references even absent any hint of suggestion in the references themselves. In such situations, the proper question is whether the ordinary artisan possesses knowledge and skills rendering him capable of combining the prior art references. Dystar Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006). In this case, Patent Owner’s contention that there is no motivation to substitute one sensor for another is not supported by anything beyond conclusory statements. Moreover, contrary to the assertion that voltage and current sensors are “not substitutable,” Nordby expressly states that “[v]oltage (potential) sensing may be used, or alternately, current (flow) sensing may be used. Since the sensing scheme is used only to detect the presence or absence of voltage or current on the sensed line and does not require any significant accuracy, the cost of either type of sense circuitry can be made very low.” Ex. 1004, 4:43–48. In light of the evidence that current and voltage sensors were known to be interchangeable, Patent Owner’s contention that there was “no reason one of skill would have sought to replace those voltage based opto-isolator systems with the bulky current transformer and attendant circuitry of Nordby,” is insufficient to demonstrate the combination of references was not obvious.

    “Fischer teaches that the comparators in coherent demodulator 114 convert a “‘spread spectrum modulated’ analog signal into a digital signal,” as opposed to “other analog signals.” See PO Resp. 13. To the contrary, Fischer states that “[t]he communicators preferably transmit and receive messages over a wireless physical layer provided by a direct-sequence, spread spectrum (DSSS) radio data link.” Ex. 1004, 14:24–27. Fischer further explains that “[s]ince many of the signals in the coherent demodulator 114 are analog signals, the coherent demodulator 114 includes comparators to establish digital waveforms.” Ex. 1004, 16:58–60. As shown in Figure 5 of Fischer, the coherent demodulator 114 is followed by spread spectrum correlator and decoder 130, which “handles the demodulator 114 output to regenerate the unspread data.” Ex. 1004, 17:58– 60. Thus, we agree with Petitioner, as supported by Prof. Ding, that a person of ordinary skill in the art “would have understood Fischer to describe that the demodulator 114 converts the analog DSSS modulated messages received by antennas 100/102 to digital signals and outputs these digital DSSS modulated messages in I and Q format to spread spectrum correlator and decoder 130.” Reply 3–4; Ex. 1013 ¶ 5.” slip op. at 18

    “The Petition makes no mention of Nakamura in its discussion of the additional limitations of claims 2 and 11. Yet in reply, Petitioner argues that “[i]n view of Fischer’s variable length preambles, a [person of ordinary skill in the art] would have found it obvious to utilize Nakamura’s timer function and its repetitive duration function.” Reply 15. Petitioner may not rely on a new argument asserting that Nakamura teaches the additional limitations for claims 2 and 11 presented for the first time in its Reply. Moreover, Petitioner fails to address how either Fischer or Nakamura teaches means for adjusting means for timing when Fischer contains no timer, and when the timer of Nakamura is described as being based on a predetermined period of time. See Ex. 1005, 6:31–36 (“timer 34 permits the switch 14 to transfer from terminal A to terminal B after the lapse of predetermined time”); see also Ex. 2006, ¶¶ 83–84. Petitioner’s contention that “Nakamura’s timer is also flexible” is insufficiently supported by any reference to either Nakamura or the declaration of Prof. Ding. See Reply 16–17; see also Ex. 1013 (no discussion of claims 2 or 11). Petitioner has not demonstrated that the features of claims 2 or 11 are disclosed by the combination of Fischer and Nakamura. 5. Claims 4, 5, 6, 13, 14, 16, and 18–20 Petitioner has persuasively shown that each of the additional limitations of dependent claims 4, 5, 6, 13, 14, 16, and 18–20 are taught by the combination of Fischer and Nakamura. For example, claims 4, 14, and 19 all require a “single monolithic device.” Petitioner has shown that Fischer RF modem 96 is a single monolithic device, and that Fischer communicator 60 is a circuit contained on a single monolithic device that includes RF modem 60. See Pet. 27–28; Ex. 1003 ¶¶ 41–42. Petitioner has also shown that RF modem 96 includes coherent demodulator 114 that provides in-phase and quadrature data outputs that are responsive to an analog signal that has in-phase and quadrature components, corresponding to the requirements of an analog signal “in the form of in-phase and quadrature components” as recited in claims 5 and 16. See Pet. 28–29; Ex. 1003 ¶ 38. With respect to the limitations of claims 6, 16, and 20 requiring PN modulation and phase shift keyed modulation, Petitioner has shown that Fischer discloses RF modem 96 supports BPSK or QPSK, and that it would have been obvious to implement direct sequence spread modulation by using PN modulation. See Pet. 29; Ex. 1003 ¶¶ 34, 37. We are also persuaded that Fischer discloses the “antenna selection circuitry” as recited in claim 13 and the “serial data stream” as recited in claim 18. See Pet. 30–31; Ex. 1003 ¶ 40. Patent Owner does not substantively dispute Petitioner’s assertion that Fischer teaches each of these limitations.” slip op. at 25

    “Patent Owner contends that “[i]f reliability alone is the concern,” then “the most reliable method is to use BPSK for the entire packet (as taught by Fischer).” PO Resp. 38. We are not, however, persuaded that “reliability alone is the concern.” Nakamura and Fischer clearly teach a benefit to using both BPSK and QPSK consisting of improved reliability for BPSK with enhanced speed from QPSK. Thus, we find Patent Owner’s contention that those of skill “would not look beyond the teachings of Fischer” unpersuasive. See id. Likewise, Patent Owner’s contention that Fischer already teaches improved reliability by using longer preambles has no bearing on whether one of ordinary skill in the art would have also looked to Nakamura for other means of improving reliability. See id. at 39. We find that Petitioner articulates sufficient reasoning with rational underpinnings. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (cited with approval in KSR Int’l. Co. v.

    “the art “would have appreciated the benefit of including multi-carrier modulation in the Wu system” because “Wu itself references the 802.11a standard as a multi-carrier OFDM scheme that is able to achieve data rates that are faster than the 802.11b transmission rates used in the Wu system.” Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68; Ex. 1108, 411). Petitioner contends that [w]ith this motivation in mind a [person of ordinary skill in the art] would have recognized that adding the multi-carrier 802.11a modulation scheme to the modulation schemes already available in the Wu system would have been a simple addition, if a technique was available for using a channel estimate obtained from data modulated according to a single carrier modulation scheme for acquisition of data modulated according to a multi-carrier modulation scheme[,] and supports that contention with testimony by Dr. Almeroth. Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68). Petitioner identifies such a technique as disclosed by Böhnke. Id. at 49. Böhnke “relates to the mapping of data and pilot symbols in an OFDM-system.” Ex. 1113, col. 1, ll. 4–5. Figure 2 of Böhnke is reproduced below. Figure 2 illustrates a sequence that includes a first OFDM modulated signal S1, a midamble MA that can be OFDM modulated or single-carrier modulated, and a second OFDM symbol S2. Id. at col. 4, ll. 36–41. The midamble can be used for the transmission of pilot symbols, which “are necessary for a channel estimation such as to effect coherent detection of e.g. OFDM-modulated signals,” and such pilot symbols can be created by a single carrier modulation with a known training sequence. Id. col. 1, ll. 7–9, col. 5, ll. 45–49, col. 5, ll. 61–63. Böhnke, thus, uses the channel estimation obtained from the single-carrier training sequence to detect multi-carrier OFDM symbols by matching bandwidth and performing synchronization. Id. at col. 2, ll. 43–45, col. 2, ll. 61–62. Petitioner reasons that the Böhnke channel-estimation techniques “provide a way to combine a high-rate, multicarrier OFDM data transmission scheme with a single carrier training sequence” and that [w]ith this background, a [person of ordinary skill in the art] investigating options for including the multi-carrier 802.11a standard in the Wu system would have appreciated that Bohnke’s channel estimation techniques could be applied to Wu’s single-carrier 802.11b preamble and used for acquisition of data modulated according to multi-carrier 802.11a.” slip op. at 12
