`
`
`
`
`
`T-Mobile USA, Inc. and T-Mobile US, Inc. (collectively, “Petitioners” or
`
`“T-Mobile”) petition for inter partes review (“IPR”) under 35 U.S.C. §§ 311–319
`
`and 37 C.F.R. § 42 of claims 1, 10, and 19 (the “Challenged Claims”) of U.S.
`
`Patent No. 5,915,210 (the “’210 patent”) and assert that there exists a reasonable
`
`likelihood that Petitioners will prevail with respect to at least one of the Challenged
`
`Claims. T-Mobile respectfully submits that an IPR should be instituted, and that
`
`the Challenged Claims should be canceled as unpatentable.
`
`I. MANDATORY NOTICES UNDER 37 C.F.R § 42.8(a)(1)
`A. Real Parties-In-Interest Under 37 C.F.R. § 42.8(b)(1)
`
`Petitioners, T-Mobile USA, Inc. and T-Mobile US, Inc., are the real parties-
`
`in-interest for the instant Petition.
`
`B. Related Matters Under 37 C.F.R. § 42.8(b)(2)
`
`T-Mobile is not aware of any terminal disclaimers for the ’210 patent. The
`
`’210 patent is presently involved in another IPR action, styled: Apple Inc. v.
`
`Mobile Telecommunications Technologies, LLC (IPR2014-01036) (filed June 27,
`
`2014) (hereinafter, the “Apple IPR”). The Challenged Claims and prior art
`
`references of the Apple IPR petition are identical to those raised by T-Mobile in
`
`the instant petition. See Ex. TMO1019. Thus, although a formal motion for joinder
`
`or consolidation of the instant action with the Apple IPR would be premature under
`
`the rules prior to an institution decision in the Apple IPR, T-Mobile respectfully
`
` 1
`
`
`
`
`
`
`
`
`
`
`
`
`submits that in view of T-Mobile challenging the ’210 Patent on the nearly
`
`identical grounds as in the Apple IPR, the Patent Trial and Appeal Board
`
`(“Board”) may wish to consider consolidating these matters already at this time.
`
`The ’210 patent is also presently involved in five pending district court litigations
`
`(the “Litigations”), one of which names T-Mobile as a defendant: Mobile
`
`Telecommunications Technologies, LLC v. Sprint Nextel Corp., Case No. 2:12-CV-
`
`832 (E.D. Tex.); Mobile Telecommunications Technologies, LLC v. Apple Inc.,
`
`Case No. 2:13-CV-258 (E.D. Tex.) (hereinafter, the “Apple litigation”); Mobile
`
`Telecommunications Technologies, LLC v. Leap Wireless International, Inc., Case
`
`No. 2-13-CV-885 (E.D. Tex.); Mobile Telecommunications Technologies, LLC v.
`
`T-Mobile USA, Inc., Case No. 2-13-CV-886 (E.D. Tex.) (hereinafter, the “T-
`
`Mobile litigation”); and Mobile Telecommunications Technologies, LLC v.
`
`Samsung Telecommunications America, LLC, Case No. 2:13-CV-259 (E.D. Tex.).2
`
`C. Counsel Under 37 C.F.R. § 42.8(b)(3) and Service Information
`
`Petitioners designate Pierre J. Hubert, Reg. No. 45,826, as Lead Counsel and
`
`Steven J. Pollinger, Reg. No. 35,326, both available at 300 West Sixth Street; Suite

`
`PAYMENT OF FEES – 37 C.F.R. § 42.103
`This Petition for IPR, which requests review of three claims (1, 10, and 19)
`
`of the ’210 patent, and which is accompanied by a payment of $23,000, meets the
`
`fee requirements under 35 U.S.C. § 312(a)(1). Petitioners authorize the Patent and
`
`Trademark Office (the “Patent Office”) to charge Deposit Account No. 50-5723 in
`
`the fee amount required for this Petition, as set in 37 C.F.R. § 42.15(a), and
`
`authorizes payment for any additional fees to be charged to this Deposit Account.
`
`III. REQUIREMENTS FOR IPR UNDER 37 C.F.R. § 42.104
`A. Grounds for Standing
`
`Petitioners certify that the ’210 patent is available for IPR and that T-Mobile
`
`is not barred or estopped from requesting an IPR challenging the ’210 patent
`
`claims on the grounds identified in this Petition. The present Petition is being filed
`
`within one year of receipt of service of the T-Mobile litigation complaint, which
`
`alleged infringement of the ’210 patent and was filed in Case No. 2:13-CV-886-
`
`JRG-RSP on October 13, 2013. See T-Mobile litigation Docket, Ex. TMO1003.
`
`B. Challenge under 37 C.F.R. § 42.104(b) and Relief Requested
`
`T-Mobile requests an IPR of the Challenged Claims on the grounds set forth
`
` 3
`
`
`
`
`
`
`
`
`
`
`
`
`in the table shown below, and requests that each of the Challenged Claims be
`
`found unpatentable. An explanation of how these claims are unpatentable under the
`
`statutory grounds identified below, including an identification of where each
`
`element is found in the prior art patents and/or printed publications and the
`
`relevance of each prior art reference, is provided in the form of detailed description
`
`and claim charts that follow. Additional explanation and support for each ground is
`
`set forth in Dr. Behnaam Aazhang’s corrected declaration, Ex.
`
`TMO1022,TMO1024 (“Aaz.”), which adopts and incorporates by reference the
`
`relevant parts of the declaration of Dr. Kakaes, Ex. TMO1004 (“Kakaes
`
`Declaration”), from the Apple IPR.

`
`the ’210 patent could be entitled. Nakamura qualifies as prior art under 35 U.S.C.
`
`§ 102(b), as it was published in April, 1987, which is more than a year before the
`
`earliest possible priority date to which the ’210 patent could be entitled. Witsaman
`
`qualifies as prior art under 35 U.S.C. § 102(e), as it was filed on August 17, 1992,
`
`which is earlier than the earliest possible priority date to which the ’210 patent
`
`could be entitled. Bingham qualifies as prior art under 35 U.S.C. § 102(b), as it
`
`was published in May, 1990, which is more than a year before than the earliest
`
`possible priority date to which the ’210 patent could be entitled. T-Mobile
`
`understands that none of these four references have ever been considered by the
`
`Patent Office with regard to the patentability of the ’210 patent.

`
`SUMMARY OF THE ’210 PATENT
`A. Brief Description
`
`The ’210 patent contains 3 independent and 16 dependent claims that each
`
`relate to combining multi-carrier modulation and simulcast broadcasting
`
`techniques. The patent’s Abstract describes the invention as follows:
`
`
`filed on December 6, 1996, which is a continuation of U.S. Application No.
`
`07/973,918 (now U.S. Patent No. 5,590,403), filed on November 12, 1992.
`
` 5
`
`
`
`
`
`
`
`
`
`
`
`
`A two-way communication system for communication betw[]een a
`system network and a mobile unit. The system network includes a
`plurality of base transmitters and base receivers include[d] in the
`network. . . The system network controls the base transmitters to
`broadcast in s[]imulcast during both systemwide and zone boundaries
`to maximize information throughout [sic, throughput].
`Ex. TMO1001, Abstract.
`
`The specification continues:
`
`Generally, simulcast technology provides multiple transmitters,
`operating on substantially the same frequencies and transmitting the
`same information positioned to cover extended areas. . .
`The base transmitters of the communication system, such as base
`transmitters 612 and 614 shown in FIG. 6, preferably utilize a multi-
`carrier modulation format as will now be described. In general, a
`multi-carrier modulation format envisions the simultaneous
`transmission of several closely spaced carrier frequencies within a
`desired frequency band, each individually modulated to convey an
`information signal. The multi-carrier modulation format
`advantageously allows for high data transfer rates by providing good
`bit rate transmission rates while keeping below the baud rate
`limitations of simulcast transmission techniques.
`Ex. TMO1001 at 1:52-55; 13:3-14.
`The 3 independent claims of the ’210 patent are challenged herein.
`
`B. Claim Construction
`
`The claims of the ’210 patent have expired and are no longer subject to
`
` 6
`
`
`
`
`
`
`
`
`
`
`
`
`amendment. Accordingly, for the purposes of this IPR action, the construction
`
`given to the Challenged Claims’ terms should be similar to that of a district court’s
`
`review. In re Rambus, Inc., 694 F.3d 42, 46 (Fed. Cir. 2012). That review
`
`standard–whereby claim terms “are generally given their ordinary and customary
`
`meaning” as understood by a person of ordinary skill in the art at the time of the
`
`invention, construing to preserve validity in case of ambiguity–suggests that the
`
`certain of the ’210 patent’s claim terms should be construed as set forth below.
`
`Phillips v. AWH Corp., 415 F.3d 1303, 1312, 1327 (Fed. Cir. 2005).
`
`Claim terms of the ’210 patent that are not addressed below are not believed
`
`to require additional clarification for purposes of the present IPR.4
`
`
`
`1.
`
` “a . . . transmitter” (Claims 1 and 10)
`
`For the purposes of this Petition, the term “a . . . transmitter” is construed by
`
`its plain and ordinary meaning, with the understanding that transmitting multiple
`
`signals or outputs from a single structural unit cannot suffice as multiple
`
`transmitters. This matches the construction used in the Apple IPR petition and also
`
`is consistent with the district court constructions in related matters including the
`
`4 In as much as 37 C.F.R. § 42.104(b)(2) defines a narrow scope of inquiry in this
`
`petition, Petitioners do not acknowledge claim compliance with 35 U.S.C. § 112,
`
`through its construction for terms that follow, or otherwise.
`
` 7
`
`
`
`
`
`
`
`
`
`
`
`
`Apple litigation. See, e.g., Ex. TMO1007, pp. 5-6 (“a person of ordinary skill in the
`
`art would understand the terms ‘transmitter’ and ‘base transmitter’ to refer to a
`
`structural unit, and thus, the number of transmitters in a given system or method is
`
`dependent on structure, not function....[T]he Court rejects [Plaintiff’s] implication
`
`that transmitting multiple signals or outputs from a single structural unit can
`
`suffice as multiple transmitters.”); Ex. TMO1006, pp. 9-10 (“[t]he Court therefore
`
`hereby construes ‘transmitter[s]’ . . . to have their plain meaning. The Court further
`
`hereby adopts the above-quoted conclusions reached in Clearwire [.]”); Ex.
`
`TMO1005 at p. 13 (“The terms ‘transmitter[s]’ and ‘base transmitter[s]’ do not
`
`require construction and should be afforded their plain and ordinary meanings[.]”).
`
`Additionally, the ’210 patent itself further suggests that a single structural unit
`
`cannot suffice as multiple transmitters if it transmits multiple signals because such
`
`a configuration is explicitly referred to as a single transmitter within the patent
`
`specification. See, e.g., Ex. TMO1001 at Figs. 13, 14; 15:47-16:31.
`
`2.
`
` “means for transmitting a first plurality of carrier signals…”
`(Claim 19)
`
`Claim 19 recites “means for transmitting a first plurality of carrier signals
`
`
`
`within the desired frequency band, each of the first plurality of carrier signals
`
`representing a portion of the information signal substantially not represented by
`
`others of the first plurality of carrier signals.” Further, as Applicant essentially
`
` 8
`
`
`
`
`
`
`
`
`
`
`
`
`admitted during prosecution–when it asserted that claim 19 included “means-plus-
`
`function recitations, rather than structural recitations as contained in independent
`
`claim 2”–this claim invokes 35 U.S.C. 112 ¶ 6. Ex. TMO1002, p. 278.
`
`A means-plus-function claim “shall be construed to cover the structure,
`
`material, or acts described in the specification and equivalents thereof”
`
`corresponding to the recited function. 35 U.S.C. § 112. In the co-pending T-Mobile
`
`litigation, Patent Owner has agreed with Petitioners that the recited function for the
`
`feature of the “means for transmitting a first plurality of carrier signals…” is
`
`“transmitting a first plurality of carrier signals within the desired frequency band,
`
`each of the first plurality of carrier signals representing a portion of the information
`
`signal substantially not represented by others of the first plurality of carrier
`
`signals.” See, e.g., Agreed Terms of Joint Claim Construction Statement from T-
`
`Mobile litigation, Ex. TMO1020.
`
`Regarding the structure that corresponds to this function, the district court in
`
`the Apple litigation applied a construction of a “means for transmitting a first
`
`plurality of carrier signals…” under 35 U.S.C. 112 ¶ 6, as corresponding to either
`
`“base transmitter 1300 including data input 1302, control logic 1304, modulators
`
`1306-1314, combiner 1316, power amplifier 1318, and an antenna 1320, as
`

`
`1400 including data input 1402, control logic 1404, modulators 1406-1414, power

`

`
`amplifiers 1416-1424, combiner 1426, and an antenna 1428, as depicted in

`
`’210 patent specification requires these components to constitute a transmitter
`
`capable of performing the recited function–or makes them “necessary,” as the
`
`Court noted in the Apple litigation–Petitioners apply the above-cited construction
`
`for the purposes of this Petition. See Ex. TMO1006, p. 31.
`
`In the alternative, if the Board determines that the structure associated with
`
`the recited function should be limited to, simply, a “transmitter”–as unsuccessfully
`
`argued by the Patentee in the Apple litigation (Ex. TMO1006, pp. 25-26)–the prior
`
`art would nevertheless meet such an interpretation of claim 19 under a similar
`
`application to that which is used for the language of claims 1 and 10. Again,
`
`alternatively, if the Board determines that, in spite of Applicant’s own explicit
`
`prosecution admissions, the ’210 claim language does not require the structure
`
`from the specification per 35 U.S.C. 112 ¶ 6, the prior art would nevertheless meet
`
`such an interpretation of claim 19 under a similar application to that which is used
`
`for the language of claims 1 and 10.

`
` “means for transmitting a second plurality of carrier signals…”
`(Claim 19)
`
`Claim 19 recites “means for transmitting a second plurality of carrier signals
`
`
`
`in simulcast with the first plurality of carrier signals, each of the second plurality of
`
`
`
`
`
`
`10
`
`
`
`
`
`
`carrier signals corresponding to and representing substantially the same
`
`information as a respective carrier signal of the first plurality of carrier signals.”
`
`Further, as Applicant essentially admitted during prosecution–when it asserted that
`
`claim 19 included “means-plus-function recitations, rather than structural
`
`recitations as contained in independent claim 2”–this claim invokes 35 U.S.C. 112
`
`¶ 6. Ex. TMO1002, p. 278.
`
`A means-plus-function claim “shall be construed to cover the structure,
`
`material, or acts described in the specification and equivalents thereof”
`
`corresponding to the recited function. 35 U.S.C. § 112. In the co-pending T-Mobile
`
`litigation, Patent Owner has agreed with Petitioners that the recited function for the
`
`feature of the “means for transmitting a second plurality of carrier signals…” is
`
`“transmitting a second plurality of carrier signals, each of the second plurality of
`
`carrier signals corresponding to and representing substantially the same
`
`information as a respective carrier signal of the first plurality of carrier signals.”
`
`See, e.g., Agreed Terms of Joint Claim Construction Statement from T-Mobile
`
`litigation, Ex. TMO1020.
`
`Regarding the structure that corresponds to this function, the district court in
`
`the Apple litigation applied a construction of a “means for transmitting a second
`
`plurality of carrier signals…” under 35 U.S.C. 112 ¶ 6, as corresponding to either
`
`“base transmitter 1300 including data input 1302, control logic 1304, modulators
`
`
`11
`
`
`
`
`
`
`
`
`1306-1314, combiner 1316, power amplifier 1318, and an antenna 1320, as
`
`depicted in Figure 13; and equivalents thereof,” or alternatively, “base transmitter
`
`1400 including data input 1402, control logic 1404, modulators 1406-1414, power
`
`amplifiers 1416-1424, combiner 1426, and an antenna 1428, as depicted in Figure
`
`14; and equivalents thereof.” Ex. TMO1006, pp. 28-30. And because the ’210
`
`patent specification requires these components to constitute a transmitter capable
`
`of performing the recited function–or makes them “necessary,” as the Court noted
`
`in the Apple litigation–Petitioners apply the above-cited construction for the
`
`purposes of this Petition. See Ex. TMO1006, p. 31.
`
`In the alternative, if the Board determines either that the structure associated
`
`with the recited function should be limited to, simply, a “transmitter” or that the
`
`’210 claim language does not require the structure from the specification per 35
`
`U.S.C. 112 ¶ 6, the prior art would nevertheless meet such an interpretation of
`
`claim 19 under an application of the prior art similar to that which is used for the
`
`language of claims 1 and 10.
`
`
`
` “transmit[ting]…in simulcast” (Claims 1, 10, and 19)
`
`For the purposes of this Petition, the terms “transmit[ting] . . . in simulcast”
`
`are construed to mean “transmitting the same information at the same time from a
`
`plurality of transmitters by modulating a plurality of carrier signals by the same
`
`information signal,” with the understanding that a single transmitter cannot operate
`
`
`12
`
`
`
`
`
`
`
`
`in simulcast with itself by using multi-carrier modulation. These constructions
`
`match the constructions proposed by T-Mobile in its co-pending litigation, and are
`
`a refinement over the constructions set forth in the Apple IPR petition and those
`
`resolved by the district court in the Apple litigation. Compare T-Mobile’s
`
`proposed construction, with Ex. TMO1019, p. 12, and Ex. TMO1006, p. 15-16.
`
`First, like Apple, T-Mobile proposes that the Board adopt the unremarkable district
`
`court finding that “a single transmitter cannot operate in simulcast with itself by
`
`using multi-carrier modulation.” Ex. TMO1007, pp. 9-10. Second, T-Mobile
`
`proposes that simulcasting, as defined by the patent, involves modulating the same
`
`underlying information signal over multiple carriers.
`
`With regard to the first aspect, T-Mobile, like Apple, merely seeks to
`
`incorporate the district court’s rejection of MTel’s argument “that, by using multi-
`
`carrier modulation, a single transmitter may operate in simulcast with itself.” Id.
`
`Specifically, as the Court concluded, the relevant “specification only envisions
`
`‘multi-carrier simulcast’ with two transmitters.” Id. (citing ’403 Pat. at 5:30-43).
`
`Further supporting T-Mobile’s proposal, the three independent claims of the ’210
`
`patent —the only independent multi-carrier simulcast claims of the asserted patent
`
`family—each require both a first transmitter [means] and a second transmitter
`
`[means] for simulcast operation of each “multi-carrier transmission system.” ’210
`
`Pat. at claims 1, 10, 19.
`
`
`
`
`
`13
`
`
`
`
`
`
`Regarding the second aspect, T-Mobile proposes a slightly narrower
`
`construction than Apple, but one that is supported by the intrinsic record. The
`
`specification repeatedly describes simulcasting, without exception, as modulating a
`
`singular information signal onto the carrier signals of more than one transmitter at
`
`the same time (i.e., in every case, there is one information signal—the same
`
`signal—modulated onto multiple carriers). See, e.g., id. at Fig. 26 (“Transmitting
`
`substantially simultaneously a first information signal and a second information
`
`signal, the first information signal being transmitted in simulcast by a first set of
`
`base transmitters”); 5:32-33 (“by modulating the first plurality of carrier signals to
`
`convey the information signal”); 6:1-8,13-21; 9:66-10:5; 24:64-25-10; 25:21-34
`
`(emphases added in both quotations). T-Mobile’s proposal is reflected in the
`
`claims themselves. See, e.g., 1:9-14; Fig. 6, claim 10 (“the first information signal
`
`being transmitted in simulcast by [the] transmitters”) (emphases added).
`
`Moreover, the specification shows that any construction of “simulcast” that
`
`does not incorporate this aspect is inconsistent with the patent, and hence incorrect.
`
`Take, for example, the patent’s focus on simulcasting’s “dead spots” at 13:38-47:
`
`It should also be understood that in accordance with good simulcast
`practice, the respective carrier frequencies between adjacent base
`transmitters, such as base transmitter 612 and base transmitter 614 in
`FIG. 6, should be slightly offset to prevent sustained nodes or ‘dead
`spots’ where destructive interference between the signals from each
`
`14
`
`
`
`
`
`
`
`
`
`
`transmitter provides an unusable composite signal, as was explained
`in the background section of this application.
`
`“Dead spots” only exist when modulating with the same underlying information
`
`signal, because only transmissions based on the same underlying information
`
`signals (but out of phase) cancel each other in this manner. See, e.g., Id. at 1:66-
`
`2:19 (“Destructive interference occurs when two signals are equal in magnitude
`
`and 180° out of phase and completely cancel each other.”). If different information
`
`signals were used, they would not “cancel each other” nor create a “dead spot.”
`
`In addition, if simulcasting did not require transmitting signals modulated
`
`using the same underlying information signal (as opposed to merely transmitting
`
`the same information at the same time), the patent claims could be read
`
`unreasonably broadly, completely divorced from the patent. Consider this analogy:
`
`If a person speaks the word “hello” into a telephone, and at the same time emails
`
`“hello” to the same recipient, that could arguably be “simulcasting” under the
`
`previous broad construction because, in a context divorced from the patent, the
`
`same information (“hello”) is being transmitted at the same time. But from a
`
`technological standpoint, the standpoint relevant to one of skill in the art of the
`
`patent, this would never be considered simulcasting in the context of the patent that
`
`uses modulation of information signals onto carriers. See Ormco Corp. v. Align
`
`Tech. Inc., 498 F.3d 1307, 1313-16 (Fed. Cir. 2007) (“[T]o attribute to the claims a
`
`
`15
`
`
`
`
`
`
`
`
`meaning broader than any indicated in the patents and their prosecution history
`
`would be to ignore the totality of the facts of the case and exalt slogans over real
`
`meaning.”).
`
`Further, T-Mobile’s proposal is in harmony with statements underlying the
`
`district court’s constructions in Clearwire and Apple, and with the Board’s past
`
`claim construction findings.5 First, the court in Clearwire correctly distinguished
`
`between transmitting the same information and transmitting the same signals. Ex.
`
`TMO1007, pp. 9-10. The court noted that the transmitted signals would, at least in
`
`some cases, not be identical due, for example, to offsets in carrier frequencies used
`
`to prevent interference. Id. Consistent with this, T-Mobile is not proposing that the
`
`transmitted signals must be identical, but rather that the underlying information
`
`signal (that is modulated onto the carriers to create the transmitted signals) must be
`
`the same for simulcasting to occur. Second, as to the Board’s previous claim
`
`interpretation from the institution of the ’403 patent, that broader construction was
`
`made before the expiration
