“the ‘first sensing circuit’ and the ‘second sensing circuit’ sense power simultaneously,” and further argues “[n]or does Patent Owner present any argument with reference to, e.g., the 459 Patent specification or prosecution history as to why this additional limitation should be read into this claim.” Pet. Reply 23. 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. Because Petitioner failed to persuasively prove that claim 2 requires only that one of two sensors senses power for the motor controller to determine that power is applied to the second input, Petitioner has not shown by a preponderance of the evidence that claim 2 of the ’459 patent is anticipated by Mullin.” slip op. at 14

“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.

“arguments and evidence concerning the construction of “streaming converter.” We first look to the full phrase that includes this claim term, namely, “a streaming converter coupled to said storage device.” The claim language informs us of the connection between the “streaming converter” and the storage device, i.e., “coupled,” and is not concerned necessarily with the format of the data, i.e. compressed. Patent Owner’s arguments, however, seemingly interpret “streaming converter” in the context of the data, without consideration of the entire claim phrase. Patent Owner does not direct us to, nor do we discern, language in the claim itself requiring the data be compressed. As for the portions of the specification identified by Patent Owner, all refer to the function performed by the streaming converter, namely to convert the compressed conversation data into a streaming format. Although the cited passages describe the voice data themselves as “compressed,” Patent Owner does not direct us to, nor can we find, disclosure in the specification necessarily limiting the voice data to a particular format for transmission, such as a compressed format. Indeed, our review of the specification reveals that: the present technology provides an Integrated Access Device (IAD) 30 wherein voice signals are converted to a digital format and routed by way of a wide area network (WAN) transport mechanism to the central data center 110 for storage. IAD 30 may be embodied as a device more commonly known as a Voice over Internet Protocol (VoIP) Gateway. It is to be specifically understood, however, that the present technology does not require specific devices or systems for implementation but rather is more broadly directed to the inclusion of devices and systems designed to convert analog voice signals into a digital format suitable for transmission over a digital network.” slip op. at 10

“dictionary definition of “Boolean search” does not support Patent Owner’s assertion that one of skill in the art would understand “logical search” to mean “Boolean search.” Reply 5–6. We agree. The proffered extrinsic evidence does not inform us sufficiently that one of skill in the art in the relevant time frame would equate a logical search with a Boolean search. Moreover, Patent Owner does not direct us to, nor can we find, any disclosure in the specification that supports Patent Owner’s proposed definition. Indeed, “logical search” is recited only in claims 16 and 17. We are not persuaded by Patent Owner’s arguments and evidence that the plain and ordinary meaning of “logical search” is a Boolean search. Nevertheless, the parties seemingly agree that a “logical search” is understood by one of skill in the communications field. PO Resp. 9; Reply 5; See Tr. 119:21–23 (“logical search was a well-known term”).

“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.

“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.

“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.

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

“Although each of the modulation schemes in this structure is a single- carrier modulation scheme, Petitioner contends that a person of ordinary skill in the art “would have appreciated the benefit of including multi-carrier modulation in the Wu system,” observing that Wu references the 802.11a standard as a multi-carrier OFDM scheme able to achieve data rates faster than the 802.11b transmission rates. Pet. 48. Petitioner supports this contention with testimony by Dr. Almeroth, which we credit. See Ex. 1103 ¶ 66. Petitioner further reasons that the addition of the multi-carrier 802.11a modulation scheme “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.” Pet. 48 (citing Ex. 1103 ¶¶ 43–47, 65–68). Petitioner cites Böhnke for such a technique. Pet. 49. We are persuaded by Petitioner’s analysis on the present record.” slip op. at 5
