`
`INTRODUCTION
`
`Patent Owner TQ Delta, LLC (“Patent Owner”) submits this preliminary
`
`response to the Petition filed by Dish, Inc. (“Petitioner”) requesting inter partes
`
`review of claims 1, 2, 4, 11, 12, 14, 16, and 18 of U.S. Pat. No. 9,094,268 (“the
`
`‘268 patent”). For the reasons discussed below, none of the asserted references,
`
`alone or in combination, disclose the claimed invention of the ‘268 patent.
`
` Contrary to Petitioner’s arguments, each of the asserted prior art references
`
`differs in significant and fundamental ways from the ‘268 patent claims. Petitioner
`
`first attempts to stretch the disclosures of the asserted references, but at least
`
`several limitations of the claims are missing from the references. Petitioner also
`
`attempts to manufacture those missing elements from the prior art by splitting the
`
`limitations of ‘268 patent claims into separate parts (and ignoring the invention as
`
`a whole) and then “modifying” the references in ways not disclosed or
`
`contemplated by the prior art—but this approach fails to establish obviousness.
`
`Further, Petitioner fails to provide any non-conclusory, non-hindsight
`
`reasons for such wholesale modifications to the prior art, and Petitioner provides
`
`no support that persons of ordinary skill in the art would have reasonably expected
`
`those modifications to even work. In doing so, Petitioner ignores numerous ways
`
`that the asserted combinations of references are incompatible.
`
`At this stage, the Board can decline instituting trial because the Petition is
`
`
`
`1
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`deficient for the following reasons:
`
`Bowie Fails to Disclose Several Claim Elements (Grounds 1, 2): In
`
`Ground 1, Petitioner first alleges that U.S. Pat. No. 5,956,323 to Bowie (“Bowie”)
`
`anticipates claims 14 and 16. Similarly, in Ground 2, Petitioner relies solely on
`
`Bowie for alleged disclosure of every element of claims 1 and 11 except for
`
`“transmitting or receiving internet and video data” (which Petitioner alleges would
`
`have been obvious in view of ADSL 1995). Bowie, however, fails to disclose at
`
`least several limitations of the claimed low power methods for a transceiver,
`
`including: (a) “entering the low power mode for the transmitter portion while the
`
`receiver portion remains in a full power mode” (Claims 11, 14 and 16), (b) “a
`
`receiver portion of the transceiver receives data during the low power mode”
`
`(Claims 1), and (c) “storing during the low power mode at least one parameter
`
`associated with the full power mode” (Claim 14).
`
`Specifically, Bowie discloses a very different way of providing a low-power
`
`mode for a transceiver compared to the ‘268 patent. Bowie discloses that, instead
`
`of having its receiver remain in full power mode or continue to receive data while
`
`the transmitter enters low power mode, its receiver also enters sleep mode. (See
`
`infra at § III.A.2(a).) Petitioner mischaracterizes a different component of Bowie
`
`as an alternative “receiver” that remains in full power mode during the
`
`transceiver’s low power mode. (See id.) But in fact, what Petitioner points to in
`
`
`
`2
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`Bowie is only a “detector” (not a receiver) that detects the presence of an
`
`unmodulated (i.e., dataless) signal in order to determine when to re-activate full
`
`power mode. (See id.) Bowie itself distinguishes that detector from a “receiver.”
`
`(See id.) Moreover, even that detector does not “remain[] in a full power mode”
`
`when the transceiver is otherwise in a low power mode—rather, it only ever
`
`operates in a low power mode. (See id.) And Petitioner’s allegation that Bowie’s
`
`detector “receives data during
`
`the
`
`low power mode” by detecting an
`
`unmodulated16 kHz resume signal is 180-degrees opposite to what Petitioner
`
`asserted during the co-pending litigation—that an unmodulated “signal” or “tone”
`
`such as Bowie’s cannot constitute “data.” (See id.)
`
`Similarly, while Bowie discloses storing certain information during low
`
`power mode in order to reduce the time for resuming full power mode, it does not
`
`disclose storing “at least one parameter associated with full power mode” (claim
`
`14). The ‘268 patent discloses that such parameters relate to the actual
`
`transmission (e.g., frequency and time-domain coefficients, transmitter gains,
`
`transmission and reception data rates, coding parameters, fine gains, and bit
`
`allocation). (See infra at § III.A.2(b).) Parameters such as these are “associated”
`
`with the full power mode because they are connected or linked to the full power
`
`mode—they inform how the full power mode is to be configured. Bowie’s stored
`
`information, in contrast, relates only to “loop characteristics” (i.e., “loop length,
`
`
`
`3
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`wire gauge, wire composition, and other factors”) that are independent of the
`
`transceiver’s full power or low power modes. (See id.)
`
`Petitioner has no support for its distorted characterizations of Bowie, which
`
`are contrary to Bowie’s express disclosure. Nor does Petitioner provide any
`
`explanation for the inconsistencies between its arguments here and its admissions
`
`in the co-pending litigation (discussed below). Petitioner only points to the bare
`
`(and incorrect) say-so of its expert, who simply repeats the arguments of the
`
`Petition. But it is well-established that such conclusory expert testimony cannot
`
`override the actual disclosure of a reference. (See infra at § III.A.1-2.)
`
`Morelli Fails to Fill in the Deficiencies in Bowie (Grounds 3-4): Perhaps
`
`recognizing that Bowie does not satisfy the above limitations of claims 1, 11, 14,
`
`and 16, Petitioner argues in Grounds 3-4 that they would have been obvious in
`
`view of Morelli. (See Pet. at 26-48.) Petitioner also argues that Morelli discloses
`
`the additional limitations of claims 2, 4, 12, and 18. (See id.) But Morelli does
`
`not, in fact, disclose the missing limitations. Petitioner’s obviousness arguments
`
`with respect to Morelli are rife with further errors and deficiencies.
`
`First, Petitioner fails to show that Morelli is analogous art to the ‘268 patent
`
`to begin with. The ‘268 patent expressly states that it is applicable only to
`
`“ADSL” and other forms of “point-to-point” communications. (See infra at §
`
`III.C.1.) In point-to-point communications, there is only communication on one
`
`
`
`4
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`line between a customer premises and one central office mode. (See id.) Morelli,
`
`however, relates to a multi-point communication system (wireless devices in
`
`communication with multiple base stations). (See id.) Petitioner fails to address
`
`numerous incompatibilities between these two different types of systems. Rather,
`
`Petitioner incorrectly over-generalizes the “field” of the ‘268 patent as simply
`
`“power conservation” or “low power” in “multicarrier communication system[s]”
`
`without any support, and summarily concludes that Morelli is ispo facto analogous
`
`art. (See id.) Petitioner’s conclusory argument in this regard, however, is no more
`
`supported than if Petitioner had alleged that the field was all “electronics.”
`
`Second, Petitioner fails to show that Morelli in fact discloses or teaches the
`
`limitations missing from Bowie. For example, Petitioner alleges that it would have
`
`been obvious to modify Bowie so that its detector circuit receives “data packets” as
`
`described in Morelli instead of just a 16 kHz signal. (See Pet. at 30.)
`
`Alternatively, Petitioner alleges that it would have been obvious to modify Bowie
`
`so that its receiver is operating in a full power mode as allegedly described in
`
`Morelli while its transmitter is in low power mode. (Id. at 32.) In fact, Morelli
`
`discloses neither of these things.
`
`Contrary to Petitioner’s characterization of Morelli, Morelli discloses a low
`
`power method for a wireless mobile device, where that device’s receiver is (just
`
`like Bowie’s) powered down during the transceiver’s low power mode, except for
`
`
`
`5
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`certain portions that remain active to detect whether there is a threshold incoming
`
`signal ready to be received. (See infra at § III.C.2(a).) Morelli expressly describes
`
`this as a low power “sleep mode” for the receiver. (See id.) Once a threshold
`
`incoming signal is detected, then Morelli’s device resumes full power. (See id.)
`
`Nowhere, however, does Morelli disclose that its receiver remains in full power
`
`mode while the transceiver is otherwise in low power mode. (See id.) Nor does
`
`Morelli disclose “transmitting or receiving a message to enter a low power mode”
`
`and “entering the low power mode [wherein/while] . . . a receiver portion of the
`
`transceiver receives data during the low power mode” (claims 1-2, 4) or
`
`“transmitting or receiving a message to enter a low power mode” and “entering the
`
`low power mode . . . while the receiver portion remains in the full power mode”
`
`(claims 11-12, 14, 16, 18). (See id. at § III.C.2(b).)
`
`Morelli likewise does not disclose “maintaining synchronization with a
`
`second transceiver during the low power mode” (Claims 2, 12). Morelli discloses
`
`that once it resumes full power, the data that is available to be received (which
`
`triggered its threshold signal detector) will begin with a synchronization signal in
`
`order to re-stabilize the communication connection. (See infra at § III.C.2(c).) But
`
`Morelli never discloses that synchronization is “maintained” during the low power
`
`mode. (See id.) Nor does Petitioner argue (because it cannot) that Morelli
`
`discloses storing any sort of “parameter associated with the full power mode”
`
`
`
`6
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`during low power mode.
`
`Third, Petitioner provides no non-conclusory reasons for why a person of
`
`ordinary skill in the art would have modified Bowie in view of Morelli to achieve
`
`the claimed invention. (See infra at § III.C.3.) For example, Petitioner summarily
`
`argues that its proposed modifications to Bowie would simply be applying a
`
`“known technique” to “yield a predictable result.” (See Pet. at 30.) But Petitioner
`
`provides no support that its proposed modifications were either a known technique
`
`or predictable—particularly given that neither Bowie, Morelli, or anything else
`
`cited by Petitioner actually discloses a “known technique” of keeping a receiver at
`
`full power during a transceiver’s low power mode. (See infra at § III.C.3.)
`
`Petitioner also argues that its proposed modification would have the benefit of
`
`“maintaining synchronization.” (See Pet. at 31.) But that is merely a circular,
`
`hindsight recitation of the very solution recited by the ‘268 patent claims. Further,
`
`Petitioner argues that Bowie itself “suggests” keeping its receiver at full power
`
`during the transceiver’s low power mode. (See Pet. at 32.) But that argument is
`
`premised on a gross mischaracterization of Bowie. (See infra at § III.C.3.) And
`
`throughout, Petitioner only relies on the conclusory say-so of its expert.
`
`Fourth, Petitioner fails to provide evidence of a reasonable expectation of
`
`success in modifying Bowie in the manner Petitioner proposes—to operate in a
`
`way that is not disclosed in any of the asserted references. (See infra at § III.C.4.)
`
`
`
`7
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`Petitioner’s proposed modification would cobble together disparate features from
`
`Bowie and Morelli, without any regard as to whether those narrow features of
`
`Morelli are compatible with other features of Bowie, and without any regard to
`
`other components and functions that Morelli needed to make its low power method
`
`work. (See id.) As discussed below, Bowie and Morelli operate in mutually
`
`inconsistent ways, and if all one did was make Petitioner’s proposed modifications
`
`to Bowie, the resulting device would in fact be inoperable. (See id.)
`
`Fifth,
`
`Petitioner
`
`does
`
`not
`
`explain
`
`how
`
`its
`
`proposed
`
`modification/combination would not change the fundamental principle of operation
`
`of Bowie. The entirety of Bowie’s disclosure (and even Bowie’s claims) are
`
`directed to a low power method that involves powering down receiving,
`
`demodulating, and processing circuitry, while only using a detector to detect an
`
`unmodulated (i.e. dataless) resume signal. (See infra at § III.C.5.) Petitioner’s
`
`proposed modification of keeping Bowie’s receiver at full power and/or enabling
`
`its detector to receive data (i.e., modulated signals) is a wholesale different
`
`“scheme.” (See id.)
`
` Accordingly, Petitioner has not carried its burden to establish a reasonable
`
`likelihood that any of claims 1, 2, 4, 11, 12, 14, 16, and 18 are unpatentable.
`
`Should the Board institute review, however, Patent Owner reserves the right to
`
`provide further technical evidence and expert testimony as to why Petitioner’s
`
`
`
`8
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`asserted references do not satisfy the limitations of the claims and/or why
`
`Petitioner’s proposed combinations would not have been obvious.
`
`II. CLAIM CONSTRUCTION
`
`Petitioner has proposed constructions for the following terms: “low power
`
`mode” (all claims), “transceiver” (all petitioned claims), and “data” (claims 1, 4,
`
`11, 16). (See Pet. at 9-10.)
`
`Patent Owner submits, however, that no construction of these terms is
`
`required. As illustrated in the arguments below, construction of these terms is not
`
`necessary in deciding whether or not to institute trial. See Wellman, Inc. v.
`
`Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011) (claim terms need only
`
`be construed “to the extent necessary to resolve the controversy”); EDMIT Indus.,
`
`Inc. v. Smartdoor Holdings, Inc., IPR2015-00013, Paper 31 (P.T.A.B. March 29,
`
`2016) (although Petitioner proposed constructions, Board agreed with Patent
`
`Owner that no constructions were necessary; “we determine that it is not necessary
`
`to construe explicitly any claim terms for purposes of this inter partes
`
`proceeding.”). Even under Petitioner’s constructions, however, Petitioner has not
`
`shown that the prior art renders any claims of the ‘268 patent unpatentable.
`

`
`
`
`
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`III. NO REVIEW SHOULD BE INSTITUTED WITH RESPECT TO THE
`GROUNDS RAISED BY PETITIONER
`
`As explained in detail below, the Petition should be denied because it fails
`
`to establish a reasonable likelihood that the challenged claims are unpatentable.
`
`The Petition proposes four grounds against the ‘268 patent:
`
`Ground 1. Unpatentability of claims 14 and 16 under 35 U.S.C. § 102(b) by U.S.
`
`Patent No. 5,956,323 to Bowie (“Bowie”).
`
`Ground 2. Unpatentability of claims 1 and 11 under 35 U.S.C. §103(a) by Bowie
`
`in view of “Network and Customer Installation Interfaces—Asymmetric Digital
`
`Subscriber Line (ADSL) Metallic Interface” (“ADSL 1995”).
`
`Ground 3. Unpatentability of claims 1, 2, 11, and 12 under 35 U.S.C. §103(a) by
`
`Bowie in view of ADSL 1995 and U.S. Pat. No. 6,236,674 to Morelli, et al.
`
`(“Morelli”).
`
`Ground 4. Unpatentability of claims 4, 14, 16, and 18 under 35 U.S.C. § 103(a)
`
`by Bowie in view of Morelli.
`
`The cited references do not, however, individually or collectively, disclose,
`
`teach, or suggest all of the elements of any of the foregoing claims. Additionally, for
`
`Grounds 2-4, the Petition also fails to provide non-conclusory, supported rationales for
`
`why the separate references would have been combined or modified. Petitioner’s
`
`proposed obviousness combinations also run afoul of basic legal principles regarding
`
`
`
`10
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`obviousness. For at least these and the following reasons, the Petition fails to
`
`establish unpatentability of the challenged claims.
`
`A. Ground 1: Petitioner Fails to Establish Anticipation by Bowie
`(Claims 14 and 16)
`
`1.
`
`Bowie’s Low Power Method is Fundamentally Different
`Than The ‘268 Patent Method
`
`
`The ‘268 patent describes and claims a multi-carrier transmission system
`
`(e.g., a Digital Subscriber Line (“DSL”) system) that has a low power sleep mode
`
`and rapid-on capability. (See Ex. 1001, ‘268 patent at Title, Abstract, Claims.)
`
`DSL transceivers consume a significant amount of power if maintained in the “on”
`
`state, even when they are not actively transmitting or receiving data. (See id. at
`
`2:60-65.) The ‘268 patent, therefore, recognized that it is desirable to limit this
`
`power consumption, “both for environmental reasons as well as to prolong the life
`
`of the equipment.” (Id. at 2:65-3:1.)
`
`The ‘268 patent also recognizes, however, that reducing power consumption
`
`is not simply a matter of just powering down components when they are not in use.
`
`That is because due to “the complexity of DSL transceivers, and the conditions
`
`under which they must operate, it is necessary to initialize them prior to the
`
`transmission and reception of data.” (Id. at 3:11-13; see also id. at 3:14-20.) The
`
`time required to initialize or re-initialize a powered-down system is generally
`
`unacceptable, since it is “typically desired to have the modem respond to request
`
`
`
`11
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`for service nearly instantaneously.” (Id. at 3:29-34.) The ‘268 patent inventors
`
`developed a method for providing a low power mode for a Customer Premises
`
`DSL transceiver (“CPE”) that would consume reduced power but nonetheless be
`
`able to resume transmission or reception almost instantaneously, e.g., within a few
`
`frames. (See id. at 3:66-4:4, 6:6-11.)
`
`The power-down operation of the CPE transceiver begins on receipt of, for
`
`example, “a power down command” from a Central Office (“CO”) transceiver.
`
`(Id. at 6:32-43.) The CPE transceiver enters low power mode by storing its “state”
`
`in memory, and then reducing power to its modulator/demodulator circuitry as well
`
`as its transmitter drivers. (Id. at 49-52.) The receiver, however, continues to
`
`receive synchronization data and is able to receive an “Awaken” signal. (See id. at
`
`7:62-8:4, 7:18-20, 7:38-61.) Once the CPE transceiver exits low power mode, the
`
`transceiver of the ‘268 is able to begin transmitting immediately or after only a few
`
`frames delay, since it does not need to repeat initializations. (See id. at 8:9-18.)
`
`Accordingly, the challenged ‘268 patent claims all first variously require that
`
`during a “low power mode” for the transceiver, at least a “transmitter portion of the
`
`transceiver does not transmit data” or the “transmitter portion” otherwise enters
`
`“the low power mode.” (See Ex. 1001, ‘268 patent at independent claims 1, 4, 11,
`
`14, 16, 18.) At the same time, however, the “receiver portion of the transceiver
`
`receives data during the low power mode” (e.g., synchronization data) or the
`
`
`
`12
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`“receiver portion remains in a full power mode.” (See id.) Certain claims further
`
`require “storing during the low power mode at least one parameter associated with
`
`the full power mode” (e.g., parameters relating to how data is to be transmitted in
`
`full power mode, such as transmission coefficients, data rates, gain, and bit
`
`allocation). (See id. at claim 14.)
`
`Bowie describes a very different method for reducing power consumption in
`
`a transceiver. Bowie describes a method that does not just power down the
`
`transmitter and FFT/modulating circuitry. Bowie powers down “signal processing
`
`111, transmitting 112, and receiving 113 circuitry.” (Ex. 1004, Bowie at 5:17-32
`
`(emphasis added).) In order to exit low power mode, Bowie includes an extra
`
`circuit (“resume signal detector 115”) that only remains active to “detect” an
`
`unmodulated (i.e., dataless) 16 kHz AC signal. (See id. at Abstract, 2:9-29, 5:48-
`
`6:2.) This “resume signal detector 115” is just a circuit that “employs conventional
`
`frequency detection techniques.” (Id. at 5:52-55.) Below is Bowie’s transceiver:

`

`
`(Id. at Fig. 1.)
`
`Bowie specifically distinguishes its “resume signal detector 115” from the
`
`separate “modulated data receive circuitry 113” that is powered down during the
`
`transceiver’s low power mode. (See id.) In other words, Bowie distinguishes
`
`between circuitry that only employs unmodulated (dataless) “frequency detection”
`
`versus different circuitry that receives modulated data in full power mode. (See
`
`id.) This is a fundamental difference between Bowie and the ‘268 patent.
`
`Another key difference is that Bowie only discloses storing during low
`
`power mode “loop characteristics” information such as “loop length, wire gauge,
`
`wire composition, and other factors.” (Ex. 1004, Bowie at 5:1-3.) In other words,
`
`Bowie discloses storing information regarding the transmission line. Bowie does
`
`not disclose storing parameters relating to the transmission or transmission mode
`
`(e.g., transmission coefficients, data rates, gain, or bit allocation). Rather, Bowie
`
`discloses that the customer and central office units can exchange “handshaking
`
`information” in order to resume full power, before exchanging data. (See Fig. 3.)

`
`Bowie Fails to Disclose All Elements of the Claims
`
`(a) “entering the low power mode for the transmitter portion
`while the receiver portion remains in a full power mode”
`(Claims 14 and 16)
`
`Contrary to Petitioner’s arguments in Ground 1, Bowie does not anticipate
`
`claims 14 or 16 of the ‘268 patent. See 35 U.S.C. § 316(e) (as the party
`
`
`
`14
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`challenging the patentability of claims, a petitioner bears the burden of proving
`
`anticipation by a preponderance of the evidence); Verdegaal Bros., Inc. v. Union
`
`Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987) (“A claim is anticipated only if
`
`each and every element as set forth in the claim is found, either expressly or
`
`inherently described, in a single prior art reference.”).
`
`At the very least, Bowie fails to disclose “entering the low power mode for
`
`the transmitter portion while the receiver portion remains in a full power mode,”
`
`which is required by both of these claims. Instead of utilizing a receiver that
`
`remains in full power mode while the transmitter enters low power mode, Bowie
`
`discloses that its receiver also enters low power mode. (See Ex. 1004, Bowie at
`
`25-27 (“Each unit 232 and 242 may then enter low-power mode by shutting off the
`
`now unnecessary sections of signal processing 111, transmitting 112, and receiving
`
`113 circuitry.”) (emphasis added).) Receiver 113 is the only component described
`
`in Bowie which can receive data. (See id. at 1:37-40 (“Signal processing
`
`electronics 111 . . . along with transmit circuitry 112 and receive circuitry 113, are
`
`used to send and receive modulated data.”), Fig. 1 (distinguishing the “modulated
`
`data receive circuitry 113” from the “resume signal detector 115”).)
`
`When the signal processing 111, transmitter 112, and receiver 113 of Bowie
`
`enter low power mode, only a “resume signal detector 115” circuit remains
`
`powered and capable of detecting a signal. (Id. at 5:28-30.) The resume signal
`
`
`
`15
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`detector 115 circuitry, however, just “detects” the presence of a 16 kHz signal
`
`using conventional “frequency detection.” (Id. at 2:38-49.) In the telephone line
`
`art, conventional “frequency detection” circuitry was well-known as a way of
`
`simply determining the presence or absence of a dataless tone. (See Ex. 2001,
`
`IEEE Dictionary (2001) at p. 296 (“detector: . . . (2) (electromagnetic energy) A
`
`device for the indication of the presence of electromagnetic fields.”).) As such,
`
`Bowie’s resume signal detector 115 is distinguishable and operates very differently
`
`from its receiver 113. Indeed, Bowie uniformly refers to its “resume signal
`
`detector 115” as only a “detector,” analogous to how a smoke alarm detects the
`
`presence of smoke rather than receives any signal or data regarding smoke, or how
`
`a baseball catcher’s eye detects an incoming ball while his mitt receives it. (See
`
`Ex. 1004, Bowie at 2:38-49, 5:47-59, 6:27-33.) Further, Bowie describes the
`
`“resume signal” as a signal that is “not a modulated data signal.” (See, e.g., id. at
`
`Claim 24.) That is distinguished from the “modulated data receiver 113” that is
`
`powered down during low power mode. (See id. at Fig. 1, 5:25-27.)
`
`Petitioner cites to no support in the Petition in Ground 1—only attorney
`
`argument—for its demonstrably incorrect argument that “the detector 115 receives
`
`the resume signal” and is therefore a “considered a receiver.” (Pet. at p. 18)
`
`Attorney argument is not evidence. See In re Geisler, 116 F.3d 1465, 1471 (Fed.
`
`Cir. 1997). Likewise, Petitioner’s expert (although not cited in Ground 1 for this
`
`
`
`16
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`proposition) simply assumes that Bowie’s detector 115 “is the claimed ‘receiver
`
`portion’” of claims 14 and 16. (See Ex. 1002, Hoarty Decl. at ¶¶ 130, 139, 145.)
`
`But Petitioner’s expert likewise provides no evidence or support that a person of
`
`ordinary skill in the art would have regarded the “detector” in Bowie as a
`
`“receiver.” (See Ex. 1002, Hoarty Decl. at ¶¶ 130, 139, 145.) To the contrary, he
`
`cites only to Bowie, which expressly states that it has a “detector 115 that employs
`
`conventional frequency detection techniques”—not a receiver. (See id. at ¶ 145.)
`
`Petitioner’s conclusory expert assertions regarding Bowie’s disclosure are
`
`also insufficient to carry Petitioner’s burden of proof. See Motorola, Inc. v.
`
`Interdigital Tech. Corp., 121 F.3d 1461, 1473 (Fed. Cir. 1997) (“An expert’s
`
`conclusory testimony, unsupported by the documentary evidence, cannot supplant
`
`the requirement of anticipatory disclosure in the prior art reference itself.”);
`
`Mobotix Corp. v. Comcam Intern., Inc., IPR2015-00093, Paper 21 (P.T.A.B. April
`
`28, 2016) (“Dr. Lavian’s testimony makes a series of speculative leaps, with little
`
`or no explanation, from
`
`the
`
`language of
`
`the cited references
`
`to his
`
`assertions regarding what the references disclose and what a person of ordinary
`
`skill in the art would have understood based on such disclosures.”); see also 37
`
`C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or
`
`data on which the opinion is based is entitled to little or no weight.”).
`
`Additionally, even if one were to incorrectly characterizes Bowie’s resume
`
`
`
`17
`
`
`
`Patent Owner’s Preliminary Response
`IPR2016-01469
`
`signal detector 115 as a “receiver,” it would still fail to satisfy claims 14 or 16.
`
`Bowie’s detector 115 is not in “full power mode” when the
