    Before MOORE, MAYER, and CHEN, Circuit Judges.
    MOORE, Circuit Judge.
    Golden Bridge Technology, Inc. (GBT) appeals from
    the district court’s grant of summary judgment that Apple
    Inc. (Apple) does not infringe the asserted claims of U.S.
    Patent Nos. 6,574,267 (the ’267 patent) and 7,359,427 (the
    ’427 patent). We affirm.
    BACKGROUND
    GBT accused Apple of infringing the patents-in-suit, 1
    which describe and claim an improvement to a Code
    Division Multiple Access (CDMA) system. ’267 patent,
    Abstract. A CDMA wireless cellular network consists of a
    base station and multiple mobile stations, such as cellular
    telephones. Golden Bridge Tech., Inc. v. Apple Inc., 
    937 F. Supp. 2d 504
    , 508 (D. Del. 2013) (Summary Judgment
    Order). To establish communication between a mobile
    station and a base station, the mobile station transmits a
    known signal called a preamble over a random access
    channel (RACH). 
    Id.
     The CDMA system allows multiple
    signals to be sent over the same RACH by using different
    numerical spreading codes in transmitting each signal.
    Spreading codes enable the mobile stations and the base
    station to distinguish a particular wireless communica-
    tion from other concurrent communications. See ’267
    patent col. 5 ll. 4–7, ll. 28–30. However, if too many
    1   The ’427 patent is a continuation of the ’267 pa-
    tent.
    GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.                 3
    mobile stations are transmitting simultaneously at high
    power levels, the signals from mobile stations can inter-
    fere with each other.
    The patents-in-suit disclose an improvement for a
    CDMA system that reduces the risk of interference be-
    tween the signals sent from various mobile stations. In
    particular, the patents-in-suit disclose that a mobile
    station seeking to communicate with the base station will
    transmit preambles at increasing power levels until it
    receives an acknowledgment signal from the base station
    indicating that the preamble was received. 
    Id.
     col. 6 ll.
    27–32, col. 7 ll. 47–51, 58–61. Once the mobile station
    receives an acknowledgment from the base station, it
    stops transmitting preambles and starts transmitting
    message information. 
    Id.
     col. 7 ll. 58–61. This ensures
    that each data signal is transmitted at the lowest power
    necessary to reach the base station, thereby reducing the
    risk of interference.
    Relevant to this appeal, GBT previously asserted the
    ’267 patent in the Eastern District of Texas (Texas Litiga-
    tion). In accordance with the parties’ stipulation, the
    Texas district court construed preamble and access pre-
    amble (collectively referred to as preamble) as “a signal
    used for communicating with the base station that is
    spread before transmission.” J.A. 3228. The district court
    subsequently granted summary judgment of anticipation,
    which we affirmed. Golden Bridge Tech. Inc. v. Nokia,
    Inc., 
    527 F.3d 1318
     (Fed. Cir. 2008). While the appeal of
    the Texas Litigation was pending before our court, GBT
    sought new claims (1) during a reexamination of the ’267
    patent and (2) in a pending continuation application,
    which issued as the ’427 patent. During prosecution of
    the ’427 patent and reexamination of the ’267 patent,
    GBT submitted to the United States Patent and Trade-
    mark Office (PTO) as part of an Information Disclosure
    Statement (IDS) the claim construction order from the
    Texas Litigation and various filings setting forth GBT’s
    4                 GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.
    stipulated definition of preamble. J.A. 1680, 1808–10,
    2008, 2127, 2639, 2641, 2679, 3228. The claims GBT
    asserted against Apple in this case are new claims that
    were either added during reexamination of the ’267
    patent or during prosecution of the ’427 patent.
    Claim 42 of the reexamined ’267 patent is representa-
    tive of the claims asserted in this litigation (emphases
    added):
    A method of transferring packet data for a mobile
    station (MS) with an MS receiver and an MS
    transmitter comprising:
    receiving at the MS receiver a broadcast common
    channel from a base station;
    determining a plurality of parameters required for
    transmission to the base station;
    spreading an access preamble selected from a set
    of predefined preambles;
    transmitting from the MS transmitter the spread
    access preamble, at a first discrete power level;
    if no layer one acknowledgment corresponding to
    the access preamble is detected, transmitting a
    spread access preamble from the MS transmitter
    at a second discrete power level higher than the
    first discrete power level; and
    upon detecting a layer one acknowledgment corre-
    sponding to a transmitted access preamble, ceas-
    ing preamble transmission and transmitting the
    packet data from the MS transmitter.
    The district court issued a claim construction order
    construing the disputed claim terms, including the term
    preamble. Golden Bridge Tech., Inc. v. Apple Inc., 
    937 F. Supp. 2d 490
    , 500 (D. Del. 2013) (Claim Construction
    Order). The court granted Apple’s motion for summary
    GOLDEN BRIDGE TECHNOLOGY     v. APPLE INC.                   5
    judgment of noninfringement based on its construction of
    preamble, and denied Apple’s motion for summary judg-
    ment of invalidity. Summary Judgment Order, at 523.
    Following the district court’s ruling on summary judg-
    ment, GBT filed an emergency motion for reconsideration.
    The court reviewed the motion but declined to grant GBT
    the relief it requested and refused to modify its summary
    judgment of noninfringement. 
    Id.
     at 523–26. The district
    court entered judgment pursuant to Rule 54(b) of the
    Federal Rules of Civil Procedure, rendering its summary
    judgment of noninfringement final. J.A. 68–69. GBT
    appeals.       We have jurisdiction under 
    28 U.S.C. § 1295
    (a)(1).
    DISCUSSION
    A. Claim Construction: preamble
    We review claim construction de novo. Lighting Bal-
    last Control LLC v. Philips Elecs. N. Am. Corp., 
    744 F.3d 1272
    , 1276–77 (Fed. Cir. 2014) (en banc). Claim terms
    are generally given their plain and ordinary meanings to
    one of skill in the art when read in the context of the
    specification and prosecution history. See Phillips v.
    AWH Corp., 
    415 F.3d 1303
    , 1313 (Fed. Cir. 2005) (en
    banc). “There are only two exceptions to this general rule:
    1) when a patentee sets out a definition and acts as his
    own lexicographer, or 2) when the patentee disavows the
    full scope of the claim term either in the specification or
    during prosecution.” Thorner v. Sony Computer Entm’t
    Am. LLC, 
    669 F.3d 1362
    , 1365 (Fed. Cir. 2012). Prosecu-
    tion disclaimer or disavowal must be clear and unmistak-
    able. Omega Eng’g, Inc. v. Raytek Corp., 
    334 F.3d 1314
    ,
    1325–26 (Fed. Cir. 2003).
    In construing the term preamble in the ’267 and the
    ’427 patents, the district court agreed with the construc-
    tion “from the Texas [L]itigation,” concluding that it was
    “still applicable insofar as [it] include[s] spreading prior to
    transmission.” Claim Construction Order, at 497. It
    6                  GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.
    construed preamble as “a signal for communicating with
    the base station that is spread before transmission and
    that is without message data.” Id. at 500.
    GBT disputes the portion of the district court’s con-
    struction requiring that the preamble be spread prior to
    transmission. It argues that the district court’s construc-
    tion departs from the plain meaning of preamble, and
    that there is no lexicography or disclaimer that would
    merit this departure. GBT also contends that it is not
    bound by its stipulated construction of preamble in the
    Texas Litigation. It argues that its submission of its
    stipulated construction to the PTO in an IDS does not
    constitute a disclaimer of the broader claim scope. GBT
    contends that, under PTO rules, submissions in an IDS
    are not admissions that the cited information is material.
    
    37 C.F.R. §§ 1.56
    (b)(2), 1.97(h); see also Abbott Labs. v.
    Baxter Pharm. Prods., Inc., 
    334 F.3d 1274
    , 1279 (Fed. Cir.
    2003) (“[W]ith the mere listing of references in an IDS,
    the applicant has admitted no more than that references
    in the disclosure may be material . . . .”). Therefore, GBT
    argues that its stipulated construction of preamble in the
    Texas Litigation does not control the meaning of preamble
    in the reexamined ’267 patent and new ’427 patent.
    We conclude that GBT’s submissions during prosecu-
    tion of its stipulated construction for the term preamble
    constitute disclaimer. Although we generally construe
    terms according to their plain and ordinary meanings to
    one of ordinary skill in the art, we depart from that
    meaning where there is disclaimer. Thorner, 669 F.3d at
    1365. Here, GBT clearly and unmistakably limited the
    term preamble to “a signal used for communicating with
    the base station that is spread before transmission.” J.A.
    2127, 3228–30, 3255–56, 3245. During reexamination of
    the ’267 patent and prosecution of the ’427 patent, GBT
    submitted and requested that the PTO “expressly consid-
    er[]” its stipulated construction of preamble from the
    Texas Litigation. J.A. 1674, 1680, 1808–10, 2007–08,
    GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.                  7
    2127, 2639, 2641, 2679. The stipulation        required the
    preamble to be spread before transmission.     Id. It would
    have been natural for both the PTO and the     public to rely
    upon the stipulation in determining the        scope of the
    claimed invention.
    It is correct that “mere disclosure of potentially mate-
    rial prior art to the [PTO] does not automatically limit the
    claimed invention.” Abbott Labs., 334 F.3d at 1279.
    However, this is not a typical IDS, and GBT did more
    than simply disclose potentially material prior art. It
    submitted its own stipulated construction of a claim term
    in the context of the particular patents being reexamined
    (’267 patent) and prosecuted (’427 patent). This is a clear
    and unmistakable assertion by the patentee to the PTO of
    the meaning and scope of the term preamble. The fact
    that the stipulation was contained in documents accom-
    panying an IDS does not change this result. We have
    held that “an applicant’s remarks submitted with an
    [IDS] can be the basis for limiting claim scope.” Uship
    Intellectual Props., LLC v. United States, 
    714 F.3d 1311
    ,
    1315 (Fed. Cir. 2013); see also Ekchian v. Home Depot,
    Inc., 
    104 F.3d 1299
    , 1303 (Fed. Cir. 1997) (“An IDS is part
    of the prosecution history on which the examiner, the
    courts, and the public are entitled to rely.”). On the facts
    of this case, we see no meaningful difference between
    limiting claim scope based on an applicant’s stipulations
    contained in IDS documents and an applicant’s remarks
    contained in the IDS itself. GBT’s stipulation tells the
    PTO how preamble should be construed, and we conclude
    that GBT is bound by this representation. We construe
    preamble in accordance with the stipulation as “a signal
    used for communication with the base station that is
    8                  GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.
    spread before transmission and that is without message
    data.” 2
    Although our precedent allows applicants to rescind a
    disclaimer during prosecution, GBT did not avail itself of
    this route and never notified the PTO that it sought a
    meaning of preamble that was different from its stipulat-
    ed construction. See, e.g., Hakim v. Cannon Avent Grp.,
    
    479 F.3d 1313
    , 1317–18 (Fed. Cir. 2007); Spring Window
    Fashions L.P. v. Novo Indus., L.P., 
    323 F.3d 989
    , 995
    (Fed. Cir. 2003) (holding the applicant to the “restrictive
    claim construction that was argued during prosecution”
    where he “never retracted any of his statements”). In-
    deed, there is no dispute that GBT did not rescind or
    retract its stipulated construction of preamble during
    prosecution of the patents-in-suit. We hold that GBT’s
    submission of its stipulation to the PTO thus constitutes a
    clear and unmistakable disclaimer of the broader claim
    scope that GBT now seeks.
    B. Summary Judgment of Noninfringement
    Applying the law of the regional circuit, we review the
    grant of summary judgment de novo. Del. Valley Floral
    Grp., Inc. v. Shaw Rose Nets, LLC, 
    597 F.3d 1374
    , 1378
    2   We note that the construction we adopt modifies
    the district court’s construction slightly. In the stipula-
    tion submitted to the PTO, GBT construed preamble as “a
    signal used for communication . . . ” but the district court
    construed preamble as “a signal for communication . . . .”
    Because we find GBT bound by its stipulation, we modify
    the construction to reflect the language of the stipulation
    which would afford broader coverage. This modification
    does not require remand as the only accused preamble
    would still not infringe because it is not spread before
    transmission.
    GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.                 9
    (Fed. Cir. 2010). We affirm summary judgment of nonin-
    fringement where “there is an absence of evidence to
    support the [patentee]’s case.” Exigent Tech. Inc. v.
    Atrana Solutions Inc., 
    442 F.3d 1301
    , 1307–10 (Fed. Cir.
    2006). Applying Third Circuit law, we review a district
    court’s grant or denial of a motion for reconsideration for
    an abuse of discretion. Koshatka v. Phila. Newspapers,
    Inc., 
    762 F.2d 329
    , 333 (3d Cir. 1985).
    GBT accused Apple’s mobile devices that use a third
    generation (3G) cellular technology of infringing various
    claims of the ’267 and ’427 patents. The accused Apple
    mobile devices send an access signal—called a Physical
    Random Access Channel (PRACH) preamble—to a specific
    base station to establish a communication link with the
    base station. The PRACH preamble is made of a combi-
    nation of (1) a base station specific scrambling code and
    (2) a signature sequence. The signature sequence is
    created first and is then spread using the scrambling code
    to create the PRACH preamble. The completed PRACH
    preamble is then transmitted to the base station.
    Throughout the case, GBT relied exclusively on the
    PRACH preamble in the accused devices to meet the
    preamble limitations in the asserted claims. Apple moved
    for summary judgment of noninfringement on the ground
    that GBT failed to create a genuine issue of material fact
    regarding whether the preamble is spread prior to trans-
    mission. Apple explained that according to GBT (citing
    GBT’s expert) the preamble of the accused device is the
    PRACH preamble, which is composed of two spreading
    codes: the signature sequence and the scrambling code.
    Apple argued that it was entitled to summary judgment
    because the PRACH preamble is not spread prior to
    transmission. Apple explained that even if the signature
    sequence is spread by the scrambling code, that “argu-
    ment is beside the point.” J.A. 2871. “The W-CDMA
    preamble signature is not, by itself, an access signal or a
    preamble.” 
    Id.
     Apple explained that “all of GBT’s evi-
    10                 GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.
    dence regarding spreading focuses entirely on the genera-
    tion of the access signal or PRACH preamble code.” J.A.
    2870. Apple’s contention was clear: the accused preamble
    was the PRACH preamble, and its motion for summary
    judgment was based on the fact that GBT did not submit
    any evidence that the PRACH preamble was spread after
    it was created.
    GBT’s response stated: “There is no dispute that the
    spread access preamble of the Accused Devices is com-
    posed of two spreading codes, i.e., the preamble signature
    sequence spread by the scrambling code.” 3 J.A. 3409.
    GBT argued that “[t]he claim language literally covers
    spreading the access preamble or preamble code either
    during construction of the spread access preamble or
    after.” J.A. 3407. Its argument was that there was no
    “temporal limitation on the spreading,” J.A. 3409, and
    thus spreading by the scrambling code during generation
    of the preamble satisfied the preamble/spreading limita-
    tion. GBT did not argue that the signature sequence was
    itself the preamble and that, therefore, there was spread-
    ing by the scrambling code after the preamble was creat-
    ed. 4
    3   GBT filed a motion for summary judgment of in-
    fringement which likewise argued that the access pream-
    ble was the signature sequence and the scrambling code.
    4   GBT did state, without citation to evidence, that
    “Vojcic [GBT’s expert] is unambiguously clear that the
    preamble signature itself is an access signal, and is
    spread by the scrambling code to increase the bandwidth
    of the preamble. . . . Apple cannot deny that the signature
    is a signal . . . .” J.A. 3409–10. GBT’s attorney argument,
    that the signature is itself a signal, is not an assertion
    that the signature signal is the preamble or the access
    preamble. And regardless, Vojcic for did not opine that
    GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.                11
    The district court rejected GBT’s PRACH preamble in-
    fringement argument and granted summary judgment of
    noninfringement to Apple. Summary Judgment Order, at
    515. The court concluded that there was no genuine
    dispute that the PRACH preamble is not spread prior to
    transmission, as required by the court’s construction of
    preamble. 
    Id.
     It determined that “GBT’s evidence, even
    if accepted, would only show that a signature—not an
    access preamble—is spread.” 
    Id.
     GBT only presented
    evidence that the signature sequence was spread during
    generation of the PRACH preamble, not that the PRACH
    preamble itself was spread. Because the PRACH pream-
    ble was the accused preamble, the court concluded that
    there is no evidence which creates a genuine issue of fact.
    Following the district court’s decision on summary
    judgment, GBT filed a motion for reconsideration arguing
    that the accused devices’ signature sequences meet the
    preamble limitations in the asserted claims. The district
    court declined to modify its judgment of noninfringement.
    Id. at 526. It described GBT’s signature sequence in-
    fringement theory as “new attorney argument,” rejected
    the theory on the merits, and again concluded that GBT
    did not raise a genuine dispute of material fact with
    respect to infringement. Id. at 525–26.
    1. PRACH Preamble (Decision on Summary Judgment)
    On appeal, GBT argues that there is a disputed issue
    of material fact that precluded summary judgment of
    noninfringement because the claims do not rule out
    the signature sequence alone is the preamble. He opined
    that the signature sequence was spread by the scrambling
    code, but like GBT’s infringement contentions, GBT’s
    expert opined that the PRACH preamble was the pream-
    ble which satisfied the claim term preamble.
    12                  GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.
    spreading during generation of the preamble. It argues
    that the accused devices spread the PRACH preamble
    during generation—in other words, the signature se-
    quence is spread by the scrambling code to create the
    PRACH preamble. GBT contends that the claim language
    covers spreading the preamble either during generation or
    after the preamble has been generated.
    We hold that the district court properly granted
    summary judgment of noninfringement. The preamble
    must be “spread prior to transmission.” The PRACH
    preamble is not spread. The signature sequence is spread
    by the scrambling code to create the PRACH preamble.
    See Appellant’s Br. 63–64. This step cannot constitute
    spreading the PRACH preamble because a preamble
    cannot be spread before it exists. Because there is no
    dispute that the PRACH preamble is not spread, it cannot
    meet the preamble limitations in the asserted claims.
    The district court properly granted summary judgment of
    noninfringement on this basis.
    2. Signature Sequence (Decision on Reconsideration)
    GBT also argues that the district court erred by de-
    clining to modify its judgment of noninfringement on
    reconsideration. GBT’s argument is two-fold. First, it
    contends that it did not waive its signature sequence
    infringement theory because that theory was not intro-
    duced for the first time in its motion for reconsideration.
    Second, on the merits, GBT argues that there is a genuine
    issue of material fact with respect to infringement based
    on its theory that the signature sequence in the accused
    devices meets the preamble limitations.
    Apple responds that GBT waived its signature se-
    quence theory by failing to present and support it at
    summary judgment. It argues that the only infringement
    theory GBT presented prior to its motion for reconsidera-
    tion was that the PRACH preamble, not the signature
    sequence, in the accused devices met the preamble limita-
    GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.                13
    tions. It argues that GBT should not be allowed to aban-
    don its infringement arguments and present new ones
    after an adverse ruling on summary judgment. On the
    merits, Apple contends that there is no genuine issue of
    material fact with respect to infringement because the
    signature sequence is not “a signal for communicating
    with the base station,” as required by the court’s construc-
    tion of preamble.
    We conclude that the district court properly refused to
    grant the relief GBT requested in its motion for reconsid-
    eration. An argument made for the first time in a motion
    for reconsideration comes too late and is ordinarily
    deemed waived. Bluebonnet Sav. Bank, F.S.B. v. United
    States, 
    466 F.3d 1349
    , 1361 (Fed. Cir. 2006); Caldwell v.
    United States, 
    391 F.3d 1226
    , 1235 (Fed. Cir. 2004);

    126 F.3d 1473
    , 1476–
    77 (Fed. Cir. 1997). Indeed, new arguments are beyond
    the scope of a motion for reconsideration. “Such motions
    are not to be used as an opportunity to relitigate the case;
    rather, they may be used only to correct manifest errors of
    law or fact or to present newly discovered evidence.”
    Blystone v. Horn, 
    664 F.3d 397
    , 415 (3d Cir. 2011).
    We conclude that GBT’s signature sequence infringe-
    ment theory was raised for the first time in its motion for
    reconsideration. Prior to its motion for reconsideration,
    GBT did not argue that the signature sequence alone in
    the accused device was itself a preamble, but instead that
    the PRACH preamble met the preamble limitations in the
    claims. Having failed to persuade the court that a genu-
    ine issue of material fact remained with respect to its
    PRACH preamble infringement theory, GBT presented a
    new infringement theory on reconsideration. This was
    improper. See Finnigan Corp. v. Int’l Trade Comm’n, 
    180 F.3d 1354
    , 1363 (Fed. Cir. 1999) (“A party’s argument
    should not be a moving target.”); Bhatnagar v. Surrendra
    Overseas Ltd., 
    52 F.3d 1220
    , 1231 (3d Cir. 1995) (rejecting
    a motion for reconsideration as a “second bite at the
    14                 GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.
    apple” and explaining that “[h]aving failed in its first
    effort to persuade the court,” the plaintiff “simply changed
    theories and tried again”); Senza-Gel Corp. v. Seiffhart,
    
    803 F.3d 661
    , 663–64 (Fed. Cir. 1986) (“[A] motion for
    reconsideration is not a chance at a second bite” and
    should not “enable the movant to ‘sandbag’ an adver-
    sary.”). It would be fundamentally unfair to allow GBT,
    after losing the claim construction arguments at issue and
    the summary judgment on its infringement contentions,
    to change those contentions. Though parties can certainly
    argue in the alternative, their infringement contentions
    cannot be a moving target. We agree with Apple that
    GBT did not argue that the signature sequence alone
    constituted the accused preamble. It is too late to do so
    for the first time in a motion for reconsideration.
    Throughout the litigation, GBT’s filings with the dis-
    trict court and its expert report identified only the
    PRACH preamble as meeting the preamble limitations in
    the asserted claims.      GBT’s expert explained “[t]he
    PRACH preamble is composed of two spreading codes
    [signature sequence and scrambling code] without mes-
    sage data.” J.A. 213. “[I]n the Accused Devices each
    access preamble is composed of two spreading codes
    [PRACH signature code and PRACH scrambling code]
    without message data.” J.A. 225. “[E]ach access pream-
    ble is formed by combining one of the available preamble
    signatures with the preamble scrambling code specific to
    the base station. The combination of an available pream-
    ble signature and scrambling code specific to the base
    station results in an access preamble.” J.A. 241. Moreo-
    ver, at the hearing, GBT characterized its expert as
    opining that the PRACH preamble was the preamble in
    the accused device. See, e.g., J.A. 3081 (explaining GBT’s
    expert’s methodology and stating that “the random access
    preamble code is formed from the preamble scrambling
    code and the preamble signature”). In fact, GBT cited in
    its summary judgment briefs, as support for the proposi-
    GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.                 15
    tion that the PRACH preamble is the accused preamble,
    the very same paragraphs of the expert report that GBT
    now claims on appeal stand for the assertion that the
    signature sequence is the accused preamble. Compare
    J.A. 3341–42 (citing J.A. 225–26, ¶74), with Appellant’s
    Br. at 52 (citing J.A. 225–26, ¶74).
    On appeal, GBT argues that the district court erred in
    its conclusion that its expert opinion “does not specifically
    address GBT’s current contention that the signature
    sequence alone constitutes a signal for communicating
    with the base station.” Appellant’s Br. at 52 (quoting
    Summary Judgment Order, at 525 n.7). We see no error
    in the district court’s interpretation of GBT’s expert
    testimony. We have reviewed the opinion cited by GBT
    and agree with the district court that GBT’s expert did
    not opine that the signature sequence alone constituted
    the accused preamble. The expert opinion repeatedly
    characterized the preamble as containing two codes
    (signature and scrambling). Though the expert referred
    to the “preamble signature,” he also referred throughout
    to the “preamble scrambling code.” See, e.g., J.A. 213–15,
    ¶¶48–49; J.A. 225–26, ¶¶74–76; J.A. 240, ¶107. GBT’s
    expert opined that these two codes (signature and scram-
    bling), which constitute the PRACH preamble in the
    accused device, together satisfy the preamble term.
    Though GBT’s expert was at times inconsistent with his
    nomenclature, he did not make the alternative argument
    that the signature sequence of the accused device alone
    satisfies the preamble term.
    Even GBT’s infringement contentions identified only
    the PRACH preamble as meeting the preamble limitation
    in the claims. “In the Accused Devices, each access pre-
    amble is composed of two spreading codes without mes-
    sage data.” See J.A. 298–99. The preamble or the access
    preamble is always identified as the combination of the
    preamble scrambling code and the preamble signature
    16                 GOLDEN BRIDGE TECHNOLOGY    v. APPLE INC.
    sequence (also sometimes referred to as the preamble
    signature signal).
    On appeal, GBT suggests that Apple’s own interroga-
    tory response combined with Apple’s own expert report
    establish that GBT raised its signature sequence in-
    fringement theory prior to its motion for reconsideration.
    Apple’s interrogatory response indicates that GBT alleged
    that the preamble limitation is met by the RACH/PRACH
    preamble part described in various sections of the stand-
    ard. J.A. 528. It is not clear that this response is an
    admission that GBT argued that the signature sequence
    alone is the preamble in the accused device. And we
    cannot find, nor has GBT directed us to, argument and
    evidence that the signature sequence is the preamble.
    GBT’s argument regarding Apple’s expert is likewise
    insufficient to establish that GBT raised its signature
    sequence infringement theory before its motion for recon-
    sideration. Apple’s expert did not opine that the signa-
    ture sequence constitutes the preamble. At most, he
    noted in multiple places that GBT’s expert was incon-
    sistent in his use of the term preamble. J.A. 635, ¶154;
    J.A. 638, ¶162. He stated: “Dr. Vojcic’s absence of a clear
    and consistent identification of what he considers to be
    meeting the claimed ‘preamble’ is of critical importance.”
    J.A. 639, ¶162. Apple’s expert addressed all the possible
    ways that GBT’s expert could be arguing that the pream-
    ble term is met in the accused device: (1) each signature,
    (2) the 256-fold repetition of these signatures, and (3) the
    combination of the signature sequence and the scrambling
    code. J.A. 637–40. Apple’s expert opined that under any
    of those interpretations Apple’s device does not meet the
    preamble limitation. This testimony by Apple’s expert,
    about GBT’s expert’s confusing and inconsistent nomen-
    clature, does not establish that GBT’s signature sequence
    theory was not new. Like the district court, we have
    reviewed the arguments and evidence submitted by GBT,
    including their expert report, and we conclude that it did
    GOLDEN BRIDGE TECHNOLOGY   v. APPLE INC.              17
    not argue that the signature sequence in the accused
    device is itself the preamble. This argument was thus
    waived.
    Because we conclude that GBT waived the signature
    sequence argument, we do not pass judgment on whether
    the signature sequence is a signal used for communicating
    with the base station that is spread before transmission.
    CONCLUSION
    We affirm the district court’s grant of summary judg-
    ment of noninfringement.
