    Before PROST, Chief Judge, DYK and O’MALLEY, Circuit
    Judges.
    O’MALLEY, Circuit Judge.
    Appellant Target Training International, Ltd. (“TTI”)
    brought suit against Extended DISC North America, Inc.
    (“EDNA”) alleging infringement of U.S. Patent No.
    7,249,372 (“the ’372 patent”). While the suit was pending,
    third-party Extended DISC International Oy Ltd. (“EDI”)
    initiated an ex parte reexamination of all claims of the
    ’372 patent. The district court litigation was stayed
    pending the resolution of the reexamination and the
    issuance of the reexamination certificate. The Patent
    Trial and Appeal Board (“Board”) ultimately determined
    that claims 1-11 (“the original claims”) of the ’372 patent
    were invalid, but confirmed that thirty claims that were
    newly added during the reexamination—claims 12-41
    (“the newly added claims”)—were patentable, and this
    court affirmed that decision under Federal Circuit Rule
    36. Following the issuance of a reexamination certificate,
    the district court granted EDNA’s motion to dismiss the
    case as moot, despite the existence of the newly added
    claims. Target Training Int’l, Ltd. v. Extended Disc North
    Am., Inc., No. 4:10-cv-03350, 
    2015 U.S. Dist. LEXIS 159526
    (S.D. Tex. June 1, 2015). Because we agree with
    the district court that the newly added claims were not
    asserted in the district court litigation prior to dismissal,
    we affirm.
    BACKGROUND
    TTI is engaged in the business of producing and
    providing individual employee assessments throughout
    the United States. It is the assignee of the ’372 patent
    which issued on July 24, 2007. The patent relates to a
    method of distributing and displaying documents on a
    website, accepting responses to the documents on the
    website, processing the responses into a report for an
    TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.           3
    interested party, and delivering the report to one or more
    locations. ’372 patent col. 2 ll. 24-28.
    Defendant EDNA is a Texas-based company with its
    principal place of business in Texas. EDI, the defendant
    in the companion case to this appeal, No. 2015-1856, is a
    Finnish company with its principal place of business in
    Finland. EDI produces and provides personality reports
    through its “Extended DISC System.” See TTI’s Prelimi-
    nary Infringement Contentions at 2, Ex. B to Defendant’s
    Motion for Summary Judgment, Target Training, 
    2015 U.S. Dist. LEXIS 159526
    (No. 4:10-cv-03350), ECF. No.
    252-3. EDI had a franchise agreement with EDNA be-
    ginning in 1996 or 1997 under which EDNA, the franchi-
    see, was given exclusive rights to distribute EDI’s product
    in the United States and Canada.
    On September 17, 2010, TTI filed a patent infringe-
    ment claim against EDNA. On January 14, 2011, third-
    party EDI filed a request for ex parte reexamination of all
    of the original claims of the ’372 patent. TTI provided
    Preliminary Infringement Contentions on February 18,
    2011 alleging infringement of claims 1, 2, and 5-11.
    EDNA moved to stay the district court proceedings pend-
    ing the outcome of the reexamination, but the court
    denied its motion. The PTO then initiated reexamination
    proceedings. The court denied three more motions to stay
    brought by EDNA, including one filed after the PTO
    issued an initial rejection of all claims and another after
    the PTO issued a final office action rejecting all claims on
    January 6, 2012.
    In July 2011, TTI filed a second complaint, this time
    against EDI, after learning through discovery in the
    EDNA matter of EDI’s ownership interest in, and exclu-
    sive franchise arrangement with, EDNA. On October 6,
    2011, EDI filed two motions to dismiss, one for lack of
    personal jurisdiction and one for the plaintiff’s failure to
    state a valid claim.
    4              TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.
    On March 26, 2012, the court in the EDI matter
    stayed its case pending resolution of the reexamination
    process. On July 25, 2012, the court in the EDNA mat-
    ter finally stayed that case until the PTO concluded
    reexamination and a certificate of reexamination was
    issued. On September 28, 2012, the court supervising the
    EDNA case entered a subsequent order stating that the
    case was “administratively closed pending the issuance of
    the certificate of reexamination.” Order Administratively
    Closing Case, Target Training, 
    2015 U.S. Dist. LEXIS 159526
    (No. 4:10-cv-03350), ECF. No. 243.
    During the stay, TTI appealed the PTO’s determina-
    tion of invalidity for anticipation to the Board, which
    affirmed on September 20, 2013. TTI then appealed to
    this court, and, after briefing and oral argument, we
    issued a Rule 36 summary affirmance. On January 12,
    2015, the PTO issued a reexamination certificate cancel-
    ling claims 1-11, but issuing thirty new claims—claims 12
    through 41—and confirming those claims as patentable.
    The district court reopened the EDNA case on Janu-
    ary 12, 2015. On January 22, 2015, EDNA moved for
    summary judgment of noninfringement and invalidity,
    and, alternatively, moved to dismiss the action as moot.
    A few days later, TTI filed a notice with the court inform-
    ing it of the reexamination certificate, stating that thirty
    new claims were added during the reexamination, and
    requesting a scheduling conference to discuss setting any
    additional or modified deadlines in order to, inter alia,
    update discovery, contentions, and expert reports. The
    court never responded to this request.
    TTI then moved to strike EDNA’s motion for sum-
    mary judgment, arguing that it was untimely under the
    original scheduling order. The court denied the motion to
    strike, reasoning that “the original scheduling order is no
    longer applicable, as . . . the case [was] stayed” and “there
    is not a scheduling order in place.” Order Denying Motion

    2015 U.S. Dist. LEXIS 159526
    (No. 4:10-cv-03350), ECF. No. 262. The court
    ordered TTI to provide a substantive response to the
    motion for summary judgment. In that substantive
    response, TTI argued that the district court was required
    to analyze whether the new claims of the ’372 patent were
    “substantively identical” to the cancelled claims before
    they could be dismissed. EDNA replied, arguing that,
    because the new claims were not included in TTI’s 3-1
    Infringement Contention Disclosures, they should not be
    considered part of the current suit. Rules of Practice for
    Patent Cases in the S.D. Tex. Rule 3-1, at http://
    www.txs.uscourts.gov/page/district-local-rules-practice-
    patent-cases.
    On June 1, 2015, the court granted EDNA’s motion to
    dismiss the case as moot, and thus did not address the
    motion for summary judgment. The court noted that the
    complaint was for infringement of the patent and, with
    the exception of claim 1, did not specify the particular
    claims infringed. “[S]ince none of the new claims were
    even part of the patent when the complaint was filed,
    [however,] TTI obviously was not alleging that EDNA was
    infringing the new, narrower claims of the reexamined
    patent. Moreover, the court agree[d] with EDNA’s con-
    tention that the disclosure pursuant to [P.R. 3-1 bound]
    TTI to its preliminary infringement contentions [ ] unless
    TTI [sought] leave of court to amend its contentions.”

    2015 U.S. Dist. LEXIS 159526
    , at *8.
    The court acknowledged TTI’s arguments that: (1) the
    new claims could be identical in scope to the original
    claims such that the case could continue under Fresenius
    USA, Inc. v. Baxter Int’l, Inc., 
    721 F.3d 1330
    , 1340 (Fed.
    Cir. 2013), and (2) even if the new claims were substan-
    tively different in scope, the case could continue based on
    ongoing infringement after the issuance of the newly
    added claims. Target Training, 
    2015 U.S. Dist. LEXIS 159526
    , at *9. Nevertheless, on June 1, 2015, the court
    6             TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.
    relied on Fresenius to dismiss the case “because all of the
    claims TTI asserted were being infringed were canceled in
    the reexamination.” 
    Id. at *10-11.
    The court’s order did
    not specify whether it was dismissing with or without
    prejudice.
    EDNA thereafter filed a Bill of Costs in the amount of
    $34,047.72, which the court taxed to TTI. On appeal, TTI
    states that, “in the event TTI’s appeal is successful,
    EDNA will no longer be the prevailing party, and this
    Court should reverse the taxing of costs.” Appellant’s Br.
    16.
    In parallel, the EDI companion case was reopened on
    January 23, 2015. The magistrate judge issued a recom-
    mendation that EDI’s Rule 12(b)(2) motion to dismiss for
    lack of personal jurisdiction be granted. On June 4, 2015,
    Judge Gilmore adopted the magistrate judge’s recommen-
    dation in its entirety and entered a final judgment of
    dismissal.
    TTI timely appeals the court’s order of dismissal and
    order taxing costs in the EDNA case. TTI also appeals
    the court’s order of dismissal in the EDI case, the compan-
    ion case on appeal. This opinion addresses only the
    EDNA case, but we are issuing our opinions in both cases
    concurrently. We have jurisdiction under 28 U.S.C.
    § 1295(a)(1).
    DISCUSSION
    The jurisdictional doctrine of mootness derives from
    Article III section 2 of the U.S. Constitution, which limits
    a federal court’s jurisdiction to live cases or controver-
    sies. 1 A justiciable controversy “must be definite and
    1   Courts often treat justiciability doctrines, includ-
    ing standing and mootness, as a subset of subject-matter
    jurisdiction.  See, e.g., Genesis HealthCare Corp. v.
    TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.            7
    concrete, touching the legal relations of parties having
    adverse legal interests.” Aetna Life Ins. Co. v. Haworth,
    
    300 U.S. 227
    , 240-41 (1937). “A justiciable controversy is
    thus distinguished from a difference or dispute of a hypo-
    thetical or abstract character; from one that is academic
    or moot.” 
    Id. at 240
    (citing United States v. Alaska S.S.
    Co., 
    253 U.S. 113
    , 116 (1920)). A moot case must, there-
    fore, be dismissed. In re Scruggs, 
    392 F.3d 124
    , 128 (5th
    Cir. 2004). Moreover, “an actual controversy must be
    extant at all stages of review, not merely at the time the
    complaint is filed.” Steffel v. Thompson, 
    415 U.S. 452
    ,
    459 n.10 (1974).
    We review a district court’s dismissal for the jurisdic-
    tional question of mootness de novo. Ford Motor Co. v.

    688 F.3d 1319
    , 1323 (Fed. Cir. 2012) (citing
    King Pharms., Inc. v. Eon Labs, Inc., 
    616 F.3d 1267
    , 1282
    (Fed. Cir. 2010)). See also Janssen Pharmaceutica, N.V.
    v. Apotex, Inc.,

    482 F.3d 1330
    , 1335-36 (Fed. Cir. 2007)).
    We first turn to the original claims, which were found
    anticipated and were cancelled as a result of the reexami-
    Symczyk, 
    133 S. Ct. 1523
    , 1532 (2013) (holding that
    district court appropriately dismissed suit for lack of
    subject matter jurisdiction when the case was moot).
    Nevertheless, the concepts derive from different textual
    sources in the Constitution and are conceptually distin-
    guishable. See Katherine Mims Crocker, Justifying A
    Prudential Solution to the Williamson County Ripeness
    Puzzle, 49 GA. L. REV. 163, 201, n.204 (2014) (“Justiciabil-
    ity can thus be thought of as a threshold concern with
    whether courts in general are equipped to resolve a dis-
    pute in the abstract, whereas subject-matter jurisdic-
    tion can be viewed as a logically subsequent inquiry into
    whether a particular court can actually do so.”).
    8              TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.
    nation. Fresenius makes clear that “when a claim is
    cancelled, the patentee loses any cause of action based on
    that claim, and any pending litigation in which the claims
    are asserted becomes 
    moot.” 721 F.3d at 1340
    . With
    respect to the original cancelled claims of the ’372 patent,
    therefore, we uphold the district court’s finding that
    Fresenius rendered the suit moot to the extent those were
    the only claims asserted in the litigation.
    We turn, next, to the fact that new claims were ap-
    proved on reexamination. TTI argues that the fact that
    new claims were added and confirmed as patentable
    through the ex parte reexamination distinguishes this
    case from Fresenius. Where newly added claims are
    substantially identical to cancelled claims, TTI argues,
    the cancellation of the original claims “shall not affect any
    action then pending nor abate any cause of action then
    existing.” 35 U.S.C. § 252. See 35 U.S.C. § 307(b). Thus,
    TTI continues, rather than dismiss the case as moot
    under Fresenius, the district court should have substan-
    tively compared the scope of the original and newly added
    claims, taking into consideration, inter alia, the specifica-
    tion, prior art references that occasioned the reexamina-
    tion, and the prosecution history, to determine whether
    the newly added claims are “substantially identical” to the
    original claims. If found “substantially identical,” then
    dismissal of the original cause of action would be inappro-
    priate, as the original claims effectively would have
    survived reexamination. Indeed, Fresenius states that
    the reexamination statute preserves the patentee’s “abil-
    ity to enforce the patent’s original claims to those claims
    that survive reexamination in ‘identical’ 
    form.” 721 F.3d at 1339
    .
    TTI further asserts that, even if the court, having per-
    formed this analysis, determined that the newly added
    claims were not substantially identical, it still should
    have allowed the proceedings to continue because TTI
    could sue EDNA for any ongoing infringement of the
    TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.            9
    newly added claims. See Laitram Corp. v. NEC Corp., 
    163 F.3d 1342
    , 1346 (Fed. Cir. 1998) (a patentee is entitled to
    damages for infringement for the period following the
    issuance of the substantively different claims from a
    reexamination).
    TTI’s characterization of Fresenius is not controver-
    sial. The question before us, however, is whether it was
    appropriate for the district court to dismiss the case when
    TTI failed to amend its infringement contentions to assert
    infringement of any of the thirty newly added claims. TTI
    argues that it was not; we disagree because the newly
    added claims were never actually asserted in the existing
    litigation.
    The district court found that TTI never asserted or
    sought to assert the newly added claims. Specifically, the
    district court found that (1) TTI “obviously” did not allege
    that EDNA infringed on the new claims at the time it
    filed its complaint because the newly added claims did not
    exist, and (2) “the disclosure pursuant to Rule 3-1 [ ] binds
    TTI to its preliminary infringement contentions.” Target
    Training, 
    2015 U.S. Dist. LEXIS 159526
    , at *9-10. It is
    undisputed that TTI’s preliminary infringement conten-
    tions only specified infringement of claims 1-2 and 5-11.
    See TTI’s Preliminary Infringement Contentions at 2, Ex.
    B to Defendant’s Motion for Summary Judgment, Target
    Training, 
    2015 U.S. Dist. LEXIS 159526
    (No. 4:10-cv-
    03350), ECF. No. 252-3. And, TTI does not dispute that
    P.R. 3-1 requires, in relevant part, that TTI identify “each
    claim of each patent-in-suit that is allegedly infringed by
    an opposing party.” Pursuant to P.R. 3-6 and 3-7, “good
    cause” must be shown in order to obtain leave to amend
    infringement contentions except in certain circumstances
    not alleged here. TTI cites no authority for the proposi-
    tion that unasserted patent claims must be considered by
    the district court prior to the dismissal of a case based on
    cancelled asserted claims. We know of no authority that
    so states.
    10             TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.
    TTI’s principal contention is that the district court
    erred in failing to permit TTI to amend its infringement
    contentions to assert the newly added claims. Appellant
    Br. 12; Appellant Reply Br. 8. TTI did not argue in its
    briefs that it had requested or moved for leave to amend
    its infringement contentions or that the court ever denied
    such a request or motion. Despite this, TTI’s counsel
    initially contended at oral argument that TTI had sought
    leave to amend and that the court failed to act on its
    request, pointing to (1) TTI’s request for a scheduling
    conference in order to set deadlines for, inter alia, updat-
    ing contentions, and (2) a footnote in its substantive
    opposition to EDNA’s summary judgment motion stating
    that, “TTI is prepared to provide amended Preliminary
    Infringement Contentions . . . pursuant to a new sched-
    ule.” Plaintiff’s Opposition to Defendant’s Motion for
    Summary Judgment at 2, n.1, Target Training, 2015 U.S.

    When pressed on whether TTI actually requested
    leave to amend its infringement contentions to allege
    infringement of the newly added claims, however, the
    following exchange took place:
    Q: Was there anything that prevented you from
    making a motion to amend the infringement con-
    tentions?
    A: I would say your honor, just the fact that we
    were waiting on the court’s response to our re-
    quest for this conference to have a scheduling or-
    der in play.
    Q: So there wasn’t any order of the court that pre-
    vented you from making such a motion?
    A: No. But the court didn’t address the issue of
    additional contentions to say whether or not we
    had the right to amend them until the dismissal
    order, at which point, of course, the case was over.

    http://oralarguments.cafc.uscourts.gov/default.aspx?fl=20
    15-1873.mp3. TTI’s counsel thus conceded that there was
    nothing preventing it from making a formal motion leave
    to amend its infringement contentions. 2
    In fact, although TTI stated that it refrained from
    making a request because it was waiting for the court’s
    response to its request for a scheduling conference, it
    knew when the court denied its motion to strike EDNA’s
    motion for summary judgment that there was “not a
    scheduling order in place.” Order Denying Motion to
    Strike at 3, Target Training, 
    2015 U.S. Dist. LEXIS 159526
    (No. 4:10-cv-03350), ECF. No. 262. If there was
    any confusion before, that denial should have been TTI’s
    cue that it was permissible for it to move for leave to
    2    The closest TTI came to making a formal motion
    for leave to amend appears in the last paragraph of its
    motion to strike, where it closed with:
    TTI respectfully requests this Court to strike
    EDNA’s Motion for Summary Judgment and reo-
    pen discovery in the case to allow the parties to
    take discovery and amend its complaint and in-
    fringement contentions to reflect the newly added
    claims of the ’372 Patent. Alternatively, if this
    Court does not strike EDNA’s Motion for Sum-
    mary Judgment as untimely and not compliant
    with the Federal Rules, TTI requests an extension
    to provide a substantive opposition relating to the
    motion’s merits.

    Dist. LEXIS 159526 (No. 4:10-cv-03350), ECF. No. 257
    (emphasis added). This request arguably was conditioned
    on the court granting TTI’s motion to strike, however,
    which the court did not do.
    12             TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.
    amend its infringement contentions. Instead, TTI pro-
    ceeded only to file its court-ordered substantive opposition
    to defendant’s motion. A district court has no obligation
    to provide relief not sought. Because TTI failed to assert
    the newly added claims, despite opportunities to do so, the
    district court did not err by dismissing the case as moot.
    We now address TTI’s concern that affirming the dis-
    missal of the proceedings would render illusory its statu-
    tory right to add new claims during reexamination under
    35 U.S.C. § 305. Appellant Br. 15-16. TTI cites Senju
    Pharm. Co. v. Apotex Inc., 
    746 F.3d 1344
    , 1353 (Fed. Cir.
    2014) as potentially precluding it from asserting the
    newly added claims in a future action, despite the fact
    that EDNA has been on notice of TTI’s intent to enforce
    the ’372 patent for five years.
    To be clear, the claim preclusion principles set forth in
    Senju would not bar a future suit on the facts of this case.
    TTI would be free to commence a new litigation asserting
    infringement of the newly added claims, and could even
    request the incorporation of discovery from the case that
    was dismissed so as not to waste judicial resources.
    Senju rests on a specific set of facts not at issue here.
    Senju recognized that claim preclusion requires “(1) a
    final judgment on the merits in a prior suit involving[ ] (2)
    the same parties or their [privies]; and (3) a subsequent
    suit based on the same cause of action.”

    (citing CoreStates Bank, N.A. v. Huls Am., Inc.,
    
    176 F.3d 187
    , 194 (3d Cir. 1999)). See also 
    Senju, 746 F.3d at 1348
    (“[U]nder the doctrine of res judicata, a
    judgment ‘on the merits’ in a prior suit involving the same
    parties or their privies bars a second suit based on the
    same cause of action.”) (quoting Lawlor v. Nat’l Screen
    Serv. Corp., 
    349 U.S. 322
    , 326 (1955)). In Senju, the
    district court in the prior action had issued findings of fact
    and conclusions of law holding that the accused product
    infringed the claims, but also that the claims were invalid
    TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.            13
    as 
    obvious. 746 F.3d at 1347
    . Thus, “both parties
    agree[d] that Senju meets the first two of the three re-
    quirements for claim preclusion,” but disagreed only with
    respect to the third requirement. 
    Id. at 1348-49.
        As a preliminary matter, the panel in Senju explicitly
    declined to opine on whether “a reexamination could ever
    result in the issuance of new patent claims that were so
    materially different from the original patent claims as to
    create a new cause of action.” 
    Id. at 1353.
    More im-
    portantly, by contrast to Senju, the district court here
    never reached a judgment on the merits. Instead, the
    court dismissed TTI’s claims as moot, and a dismissal for
    mootness is a dismissal for lack of jurisdiction. A dismis-
    sal for lack of jurisdiction is not a dismissal on the merits.
    Rather, the Supreme Court has specifically rejected
    deciding the merits of a case where the court lacks juris-
    diction because jurisdiction is a threshold question, and
    “[w]ithout jurisdiction the court cannot proceed at all in
    any cause.” Steel Co. v. Citizens for a Better Env’t, 
    523 U.S. 83
    , 94 (1998) (quoting Ex parte McCardle, 
    74 U.S. 506
    , 514 (1869)). See also Orff v. United States, 
    358 F.3d 1137
    , 1149-50 (9th Cir. 2004) (citing, inter alia, Cupey
    Bajo Nursing Home, Inc. v. United States, 
    23 Cl. Ct. 406
    ,
    412 (1991) (“It is well settled that a question relating to
    subject matter jurisdiction goes to the very heart of our
    power to hear a controversy, and any decision on the
    merits rendered in the absence of such authority would, of
    course, be a nullity.”)).
    In addition, we have held that, in patent cases, res ju-
    dicata does not apply to bar the assertion of new claims
    acquired during the pendency of a litigation that could
    have been, but were not, litigated or adjudicated in the
    action. Aspex Eyewear, Inc. v. Marchon Eyewear, Inc., 
    672 F.3d 1335
    , 1345 (Fed. Cir. 2012) (“While a party may seek
    to pursue claims that accrue during the pendency of a
    lawsuit adjudicated in that lawsuit, the party is not
    required to do so, and res judicata will not be applied to
    14            TARGET TRAINING INT’L   v. EXTENDED DISC N. AM.
    such accruing claims if the party elects not to have them
    included in the action.”) (citing Gillig v. Nike, Inc., 
    602 F.3d 1354
    , 1363 (Fed. Cir. 2010)).
    Nothing in this opinion shall be construed as passing
    judgment on whether we believe a future action brought
    by TTI against EDNA and EDI for alleged infringement of
    the ’372 patent ultimately would be successful on the
    merits. If that suit were brought, it would be up to the
    district court to assess whether the newly added claims
    are of the same substantive scope as the cancelled claims
    and to proceed from there. A finding that the new claims
    are not substantively identical in scope would result in
    the limitation of TTI’s potential recovery only to in-
    fringement of the claims for the period following the
    issuance of the reexamination certificate, but it would not
    preclude those claims. 
    Laitram, 163 F.3d at 1346
    .
    CONCLUSION
    Because the district court did not err in dismissing
    the suit as moot in light of the cancellation of the only
    claims asserted in the case, we affirm.
