    UNITED SERVICES AUTOMOBILE ASSOCIATION
    TARANTO, Circuit Judge.
    In November 2019, Mitek Systems, Inc. brought suit in
    the United States District Court for the Northern District
    of California against United Services Automobile Associa-
    tion (USAA). It sought a declaratory judgment, under the
    Declaratory Judgment Act, 
    28 U.S.C. § 2201
    (a), that Mitek
    and its customers have not infringed, either directly or in-
    directly, any valid and enforceable claim of USAA’s U.S.
    Patent Nos. 8,699,779, 9,336,517, 8,977,571, and 9,818,090
    (hereinafter referred to as the patents-in-suit). In re-
    sponse, USAA filed a motion making two requests. It
    sought dismissal of the complaint on the grounds that
    there was no case or controversy between USAA and Mitek
    as required by Article III of the Constitution, so the case
    should be dismissed under Federal Rule of Civil Procedure
    12(b)(1) for lack of subject-matter jurisdiction, and in any
    event, the court should exercise discretion not to hear
    Mitek’s claim for declaratory relief. In the alternative,
    USAA requested transfer of the action to the United States
    District Court for the Eastern District of Texas pursuant to
    
    28 U.S.C. § 1404
    .
    In April 2020, the California court, without ruling on
    the dismissal part of the motion, ordered the case trans-
    ferred to the Texas forum. Mitek Systems, Inc. v. United
    Services Automobile Association, No. 19-cv-07223, 
    2020 WL 1922635
     (N.D. Cal. Apr. 21, 2020) (Transfer Order). In
    April 2021, the Texas court dismissed for want of a case or
    controversy and stated that, even if jurisdiction existed, it
    would exercise its discretion to decline to entertain the de-
    claratory-judgment action. Order, Mitek Systems, Inc. v.
    United Services Automobile Association, No. 2:20-cv-00115
    (E.D. Tex. Apr. 28, 2021), ECF No. 69 (Dismissal Order);
    see also J.A. 11–19. On Mitek’s appeal, we vacate the
    Texas court’s dismissal and remand for further proceed-
    ings. The remand is to the Texas court because we affirm
    the California court’s transfer order.

    A
    USAA, a reciprocal inter-insurance exchange, is orga-
    nized under Texas law and has its principal place of busi-
    ness in San Antonio, Texas. USAA owns the four patents-
    in-suit, all of which address the use of a mobile device to
    capture an image of a bank check and to transmit it for de-
    posit. The related ’779 and ’517 patents describe an “align-
    ment guide . . . in the field of view of a camera associated
    with a mobile device used to capture an image of a check.”
    ’779 patent, col. 1, lines 40–42; ’517 patent, col. 1, lines 51–
    53. “When the image of the check is within the alignment
    guide in the field of view, an image may be taken by the
    camera and provided from the mobile device to a financial
    institution.” ’779 patent, col. 1, lines 42–45; ’517 patent,
    col. 1, lines 53–56. Similarly, the related ’571 and ’090 pa-
    tents describe “[t]he monitoring” of an image of a check
    that is in the field of view of the camera, which “may be
    performed by the camera, the mobile device and/or finan-
    cial institution that is in communication with the mobile
    device.” ’571 patent, col. 1, lines 38–43; ’090 patent, col. 1,
    lines 51–56. “When the image of the check in the field of
    view passes monitoring criteria,” such as criteria for proper
    lighting or framing, “an image may be taken by the camera
    and provided from the mobile device to a financial institu-
    tion.” ’571 patent, col. 1, lines 43–46; 
    id.,
     col. 3, lines 58–
    61; ’090 patent, col. 1, lines 56–59; 
    id.,
     col. 4, lines 10–13.
    For the purposes of this appeal, Mitek deemed claim 1
    of the ’779 patent to be representative, which recites:
    1. A system for depositing a check, comprising:
    a mobile device having a camera, a display and a
    processor, wherein the processor is configured to:
    project an alignment guide in the display of
    the mobile device, the display of the mobile

    device displaying a field of view of the cam-
    era;
    monitor an image of the check that is
    within the field of view;
    determine whether the image of the check
    aligns with the alignment guide;
    automatically capture the image of the
    check when the image of the check is deter-
    mined to align with the alignment guide;
    and
    transmit the captured image of the check
    from the camera to a depository via a com-
    munication pathway between the mobile
    device and the depository.

    Mitek is a Delaware corporation and has its headquar-
    ters and principal place of business in San Diego, Califor-
    nia. 1 Mitek created software for mobile check capture that
    provides “automatic image capture technology,” J.A. 494
    (Carnecchia Decl. ¶ 3) (capitalization altered), which ena-
    bles the “instant capture of quality images with a mobile or
    desktop device,” J.A. 36 (Compl. ¶ 28). It licenses the soft-
    ware, through a product it calls MiSnap™, in the form of a
    development kit to financial institutions, often indirectly
    through third-party providers of services to such
    1   We recite facts from the complaint and from addi-
    tional evidence submitted in the district court—without en-
    dorsing the assertions of fact—that play roles in the
    disposition of the motions at issue discussed later in this
    opinion.

    institutions. J.A. 29, 36 (Compl. ¶¶ 3, 28); J.A. 494–96
    (Carnecchia Decl. ¶¶ 2–7).
    Mitek alleges that, in early 2017, USAA (through its
    attorneys at Epicenter Law, based in Burlingame, Califor-
    nia) began sending licensing letters to financial institu-
    tions, including Mitek customers. J.A. 29–30 (Compl. ¶ 8).
    After a Mitek customer, Wells Fargo Bank (headquartered
    in San Francisco), received its letter from USAA, USAA
    and Wells Fargo held discussions in May and June of 2018.
    J.A. 30 (Compl. ¶¶ 9–10). But in June 2018, USAA sued
    Wells Fargo for infringement of the patents-in-suit in the
    Eastern District of Texas. See Complaint, United Services
    Automobile Association v. Wells Fargo Bank, N.A.,
    No. 2:18-cv-00245 (E.D. Tex. June 7, 2018), ECF No. 1. In
    its First Amended Complaint against Wells Fargo, USAA
    mentioned Mitek and/or MiSnap™ at least twice. J.A. 93–
    95 (First Am. Compl. ¶¶ 29, 36). As the case progressed,
    USAA served Mitek with a subpoena pursuant to Federal
    Rules of Civil Procedure 26, 34, and 45 and obtained docu-
    ments, source code, and testimony from Mitek regarding
    the operation of MiSnap™. J.A. 633–57. The case went to
    trial on October 30, 2019, on two of the four patents-in-suit
    (the ’571 and ’090 patents), and Mitek and its product were
    frequently mentioned in the litigation of USAA’s infringe-
    ment charge. E.g., J.A. 515–17; J.A. 686; J.A. 720–23.
    On November 1, 2019, the third day of the Wells Fargo
    trial, Mitek filed a complaint against USAA in the North-
    ern District of California, seeking a declaratory judgment
    that “Mitek and its customers have not infringed, either di-
    rectly or indirectly, any valid and enforceable claim” of any
    of the patents-in-suit. J.A. 38–42 (Compl. ¶¶ 35–58,
    Prayer for Relief A–D). In the section of this declaratory-
    judgment complaint addressing jurisdiction, Mitek made a
    number of allegations.
    First, Mitek alleged that USAA “sent over 1,000 patent
    licensing demand letters to financial [institutions] across
    Case: 21-1989    Document: 34      Page: 6    Filed: 05/20/2022
    6                                   MITEK SYSTEMS, INC. v.
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    the country, most of which are Mitek customers,” and that
    “[t]hese letters explained that ‘USAA has asked Epicenter
    Law to approach financial institutions to offer a license, on
    reasonable terms, as fair compensation for the continued
    use of [its] patent-protected invention.’”       J.A. 29–30
    (Compl. ¶ 8) (quoting J.A. 44 (Compl. Ex. A)). According to
    Mitek, “at least some of these letters included one or more
    ‘claim charts’ detailing Mitek’s customers’ infringement of
    one or more of the Patents-in-Suit as well as a ‘Patent List’
    identifying one or more of the Patents-in-Suit.” J.A. 30
    (Compl. ¶ 8) (citing J.A. 43–82 (Compl. Ex. A)). Mitek also
    alleged that “[i]n response to USAA’s massive patent en-
    forcement and letter writing campaign, Mitek has received
    demands for indemnification from its customers and sup-
    pliers pursuant to” contractual agreements with its cus-
    tomers, which include “indemnification provisions relating
    to actual or alleged patent infringement by Mitek’s tech-
    nology.” J.A. 31–32 (Compl. ¶ 13). To support these
    claims, Mitek attached one letter as an exhibit: a USAA
    licensing letter sent to Mitek customer Mission Federal
    Credit Union on January 22, 2018, which included a claim
    chart for claims of 
    U.S. Patent No. 8,708,227
     (not one of the
    patents-in-suit and from a different family), and a Patent
    List that included over 70 patents, including three of the
    four patents-in-suit. J.A. 43–82 (Compl. Ex. A). Mitek did
    not give concrete examples regarding indemnification or
    attach any documents embodying an indemnification
    agreement or a demand for indemnification from any of its
    customers.
    Second, concerning the Wells Fargo litigation, Mitek
    alleged that USAA “implicitly accused Mitek of encourag-
    ing and contributing to the infringement of each of the Pa-
    tents-in-Suit by supplying its MiSnap™ technology to
    financial institutions for incorporation within their mobile
    banking applications,” J.A. 30–31 (Compl. ¶¶ 11–12), and
    Mitek attached USAA’s First Amended Complaint against
    Wells Fargo as an exhibit, J.A. 83–131 (Compl. Ex. B).
    Case: 21-1989    Document: 34      Page: 7    Filed: 05/20/2022
    MITEK SYSTEMS, INC. v.                                     7
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    Elaborating on the allegation, Mitek asserted that “[o]n in-
    formation and belief, in the Wells Fargo lawsuit, USAA has
    accused Wells Fargo Bank of infringing each of the Pa-
    tents-in-Suit at least in part by virtue of Wells Fargo
    Bank’s use of Mitek’s software and technology, including
    MiSnap™,” and that “USAA also alleged in the Wells Fargo
    lawsuit that the accused Mitek technology being used by
    Wells Fargo has no substantial non-infringing uses.” J.A.
    31 (Compl. ¶ 12). Mitek concluded: “Mitek therefore has a
    real and substantial apprehension of imminent litigation
    between Mitek and USAA for direct infringement, induce-
    ment, and contributory infringement of the Patents-in-
    Suit.” J.A. 31 (Compl. ¶ 12).
    Five days after Mitek filed its declaratory-judgment
    complaint in the California forum, the jury in the USAA
    case against Wells Fargo in the Texas forum rendered a
    verdict for USAA. See Jury Verdict, United Services Auto-
    mobile Association v. Wells Fargo Bank, N.A., No. 2:18-cv-
    00245 (E.D. Tex. Nov. 6, 2019), ECF No. 322. A couple of
    months later, after USAA obtained an additional verdict
    against Wells Fargo on two other patents, a news article
    commented that USAA “hailed the latest decision and sug-
    gested [that] other banks should be on alert if they use the
    same technology” as Wells Fargo. J.A. 768–70 (also stating
    “[t]hese lawsuits have repercussions for the industry, be-
    cause Mitek’s technology is used by 6,500 other institu-
    tions”).
    C
    On January 15, 2020, in Mitek’s declaratory-judgment
    action in California, USAA moved for dismissal under Rule
    12(b)(1) for lack of subject-matter jurisdiction, or for dis-
    missal based on the discretion granted to the district court
    by the Declaratory Judgment Act. J.A. 254–73. In the al-
    ternative, USAA sought transfer to the Eastern District of
    Texas. J.A. 273–77. In support of its motion, USAA
    Case: 21-1989     Document: 34     Page: 8    Filed: 05/20/2022
    8                                    MITEK SYSTEMS, INC. v.
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    submitted additional evidence, including documents and
    transcripts from the Wells Fargo litigation. J.A. 278–80.
    On April 21, 2020, the California district court granted
    USAA’s motion to transfer the declaratory-judgment action
    to the Eastern District of Texas, without ruling on the mo-
    tion to dismiss. Transfer Order, 
    2020 WL 1922635
    , at *1.
    After determining that the action could have been filed in
    the Eastern District of Texas, the California district court
    analyzed whether the convenience of parties and wit-
    nesses, and the interests of justice, weighed in favor of a
    transfer. 
    Id. at *3
    . The court determined that the re-
    quested transfer would “facilitate at the very least coordi-
    nation” with the Wells Fargo litigation (tried by Judge
    Gilstrap in the Eastern District of Texas), which involved
    the same patents and technology; that Mitek’s choice of fo-
    rum in the Northern District of California was entitled to
    little deference; and that witness convenience was a neu-
    tral consideration. 
    Id.
     at *3–5.
    On July 15, 2020, Judge Gilstrap, having received the
    transferred case, heard argument from counsel on the mo-
    tion to dismiss. J.A. 957–1014. Eight months later, in
    March 2021, Mitek filed a supplemental brief, informing
    the court of subsequent developments and submitting ad-
    ditional evidence. J.A. 1015–19. Specifically, Mitek in-
    formed the court that, in February 2021, Wells Fargo and
    USAA had settled their dispute but that, in December
    2020, USAA had filed suit against another Mitek customer,
    PNC Bank, for infringement of two of the four patents-in-
    suit and that PNC had, through a third-party intermedi-
    ary, made an indemnity demand. J.A. 1016–17; see also
    J.A. 1035–36.
    The next month, on April 28, 2021, the district court
    granted USAA’s motion to dismiss, ruling that there was
    no case or controversy between the parties. Dismissal Or-
    der at 8. The district court viewed Mitek’s basis for subject-
    matter jurisdiction as resting on either (1) the Wells Fargo
    Case: 21-1989     Document: 34      Page: 9   Filed: 05/20/2022
    MITEK SYSTEMS, INC. v.                                      9
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    litigation or (2) USAA’s letters to Mitek customers and in-
    demnification demands assertedly received by Mitek, but
    the court found each basis insufficient to support jurisdic-
    tion. 
    Id.
     at 2–8. Alternatively, the district court noted that
    “[e]ven if the Court’s determination that subject matter ju-
    risdiction is lacking were later set aside, the Court would
    similarly and for the same reasons exercise its discretion
    and decline to exercise jurisdiction over Mitek’s declaratory
    judgment action.” 
    Id.
     at 8–9.
    Mitek timely appealed. We have jurisdiction pursuant
    to 
    28 U.S.C. § 1295
    (a)(1).
    II
    A
    Whether the district court had subject-matter jurisdic-
    tion is a question we review de novo. Microsoft Corp. v.
    DataTern, Inc., 
    755 F.3d 899
    , 903 (Fed. Cir. 2014). But the
    evaluation is based on the particular facts (determined ac-
    cording to the procedural posture). The Supreme Court has
    recognized that its precedents “do not draw the brightest of
    lines between those declaratory-judgment actions that sat-
    isfy the case-or-controversy requirement and that do not,”
    and that, where jurisdiction is being assessed based on the
    complaint, “[b]asically, the question in each case is whether
    the facts alleged, under all the circumstances, show that
    there is a substantial controversy, between parties having
    adverse legal interests, of sufficient immediacy and reality
    to warrant the issuance of a declaratory judgment.”
    MedImmune, Inc. v. Genentech, Inc., 
    549 U.S. 118
    , 127
    (2007) (citation omitted). That formulation—which “sum-
    marize[s]” a formulation focusing on whether the dispute
    is “definite and concrete, touching the legal relations of
    parties having adverse legal interests,” is “real and sub-
    stantial,” and “[admitting] of specific relief through a de-
    cree of a conclusive character”—indicates the importance
    of identifying the particular facts that may bear on
    Case: 21-1989     Document: 34     Page: 10    Filed: 05/20/2022
    10                                   MITEK SYSTEMS, INC. v.
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    whether the standard is met in a given case, in light of “all
    the circumstances.” 
    Id.
     (citation omitted).
    The case-or-controversy inquiry has a dual temporal fo-
    cus. First, “[a] declaratory judgment plaintiff must plead
    facts sufficient to establish jurisdiction at the time of the
    complaint, and post-complaint facts cannot create jurisdic-
    tion where none existed at the time of filing.” Microsoft,
    755 F.3d at 906; see also Matthews Int’l Corp. v. Biosafe
    Engineering, LLC, 
    695 F.3d 1322
    , 1331 (Fed. Cir. 2012);
    Innovative Therapies, Inc. v. Kinetic Concepts, Inc., 
    599 F.3d 1377
    , 1383–84 (Fed. Cir. 2010). Second, a case or con-
    troversy must remain present throughout the course of the
    suit. See Preiser v. Newkirk, 
    422 U.S. 395
    , 401–02 (1975);
    Int’l Medical Prosthetics Research Associates, Inc. v. Gore
    Enterprise Holdings, Inc., 
    787 F.2d 572
    , 575 (Fed. Cir.
    1986).
    Different procedural routes are available to identify the
    facts underlying the case-or-controversy determination,
    and clarity about which route is used is important, in part
    because the parties should know what opportunities they
    have for establishing facts of potential significance and,
    later, because the standard of appellate review is affected
    by the route taken. Thus, when determining whether there
    was standing at the time of the filing of the action based on
    pre-complaint events, and whether standing was main-
    tained thereafter, the district court may rely on pleaded
    and undisputed facts or on findings that resolve factual dis-
    putes, reflecting the different possible treatments of a mo-
    tion to dismiss for lack of jurisdiction under Rule 12(b)(1).
    Under Fifth Circuit precedent, which we follow on a non-
    patent-specific issue such as this, a Rule 12(b)(1) motion
    sometimes calls for adjudication of factual disputes and
    sometimes does not:
    [T]he district court is to accept as true the allega-
    tions and facts set forth in the complaint. Addition-
    ally, “the district court is empowered to consider
    Case: 21-1989    Document: 34      Page: 11     Filed: 05/20/2022
    MITEK SYSTEMS, INC. v.                                      11
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    matters of fact which may be in dispute.” The dis-
    trict court consequently has the power to dismiss
    for lack of subject matter jurisdiction on any one of
    three separate bases: (1) the complaint alone;
    (2) the complaint supplemented by undisputed
    facts evidenced in the record; or (3) the complaint
    supplemented by undisputed facts plus the court’s
    resolution of disputed facts.
    Choice Inc. of Texas v. Greenstein, 
    691 F.3d 710
    , 714 (5th
    Cir. 2012) (citations omitted); see also Montez v. Dep’t of the
    Navy, 
    392 F.3d 147

    TCI/US West Communications Inc., 
    117 F.3d 900
    , 904 (5th
    Cir. 1997). In the specific setting of a case-or-controversy
    challenge, the Fifth Circuit has said that a challenge is
    “factual” rather than “facial” “if the defendant ‘submits af-
    fidavits, testimony, or other evidentiary materials.’” Supe-

    defeat a factual attack, a plaintiff ‘must prove the existence
    of subject-matter jurisdiction by a preponderance of the ev-
    idence’ and is ‘obliged to submit facts through some eviden-
    tiary method to sustain his burden of proof.’”

    B
    In this case, Mitek’s jurisdictional argument rests on
    two bases. Mitek builds on our recognition of certain suffi-
    cient conditions for finding a case or controversy:
    [W]here a patent holder accuses customers of direct
    infringement based on the sale or use of a supplier’s
    equipment, the supplier has standing to commence
    a declaratory judgment action if (a) the supplier is
    obligated to indemnify its customers from infringe-
    ment liability, or (b) there is a controversy between
    the patentee and the supplier as to the supplier’s
    liability for induced or contributory infringement
    based on the alleged acts of direct infringement by
    its customers.
    Arris Group, Inc. v. British Telecommunications PLC, 
    639 F.3d 1368
    , 1375 (Fed. Cir. 2011). Reversing the order, and
    urging that it need not concede an indemnity obligation for
    customers’ demands for indemnification to suffice, Mitek
    asserted in the district court, and asserts here, that it
    meets the MedImmune standard on each of two bases:
    (a) its potential liability for infringement; and (b) the al-
    leged demands for indemnity made by many of its licensees
    after USAA sent them letters seeking to sell them licenses
    to USAA patents. Mitek Opening Br. 14–26.
    To a large extent, the parties have debated the case-or-
    controversy issue at too high a level of generality. The is-
    sues raised by Mitek’s asserted bases of jurisdiction, we
    conclude, require finer parsing of the issues and more par-
    ticularized determinations than we have before us, both
    from the parties and from the district court. Moreover, the
    district court was unclear in identifying whether it was
    treating the Rule 12(b)(1) motion as a facial challenge or as
    a factual challenge, in whole or in part, and the parties
    themselves have been unclear about this. We hold that fur-
    ther proceedings are needed in order for the case-or-contro-
    versy determination to be made and that, subject to
    Case: 21-1989    Document: 34      Page: 13    Filed: 05/20/2022

    forfeiture determinations we leave initially to the district
    court, the proceedings should include additional fact-find-
    ing proceedings. We therefore vacate the jurisdictional dis-
    missal.    We remand for further proceedings on the
    jurisdictional issue—and also, as we conclude in Part III
    infra, on the issue of discretion-based dismissal.
    1
    Mitek’s first asserted basis of a case or controversy is
    its potential liability to USAA for infringement. In arguing
    for the existence of a case or controversy on that basis, at
    least as of the time of filing of the declaratory-judgment ac-
    tion, Mitek focused on what had occurred in USAA’s suit
    against Wells Fargo. The trial in the Wells Fargo case was
    in progress at the time Mitek filed for a declaratory judg-
    ment on November 1, 2019. Though the jury rendered a
    verdict in USAA’s favor a few days later, the case was not
    resolved until more than a year later, shortly before the
    district court ruled on the motion to dismiss, which had
    been filed in January 2020 and on which the district court
    in Texas had heard argument in July 2020.
    The district court concluded that “the Wells Fargo Case
    could not have provoked in Mitek a reasonable apprehen-
    sion of suit by USAA.” Dismissal Order at 6. 3 The district
    3    The Supreme Court in MedImmune rejected a gen-
    eral requirement of a reasonable apprehension of suit.

    tronics, Inc., 
    480 F.3d 1372
    , 1380 (Fed. Cir. 2007). Here,
    however, the district court’s use of that concept is directly
    responsive to Mitek’s particular theory as to whether Arti-
    cle III standing existed under the MedImmune standard.

    court did not determine that USAA had disclaimed any in-
    terest in suing Mitek or had made a strategic decision (e.g.,
    that all actions for infringement of the patents-in-suit
    should be against banks and other Mitek customers, not
    Mitek) that a suit against Mitek was not reasonably possi-
    ble. And we find several ways in which the reasons the
    district court did give are inadequate on the record before
    us.
    The court reasoned that “Mitek sitting on its hands
    during the Wells Fargo Case and neglecting to intervene is
    probative (and perhaps the best indicator) as to . . . any ac-
    tual apprehension Mitek felt with regard to litigation by
    USAA.” 
    Id. at 4
    . But the court did not explain why Mitek’s
    “neglecting to intervene”—a point distinct from the simple
    fact that USAA had not (yet) sued Mitek or might even pre-
    fer to sue individual banks—has particular weight as a ba-
    sis for concluding that Mitek had no reasonable
    apprehension of itself being sued. Assessing the weight of
    the choice not to intervene (in USAA’s first suit on these
    patents) would require considering the legal, factual, and
    contextual factors bearing on the opportunity for interven-
    tion and the benefits of intervention in another’s suit com-
    pared to alternatives. The district court’s opinion does not
    include such an analysis of the intervention choice, and in
    the absence of such an analysis, we do not see how the de-
    cision not to intervene in the first suit on the patents counts
    materially against a finding of a reasonable apprehension
    of suit.
    The district court also reasoned that the substance of
    the evidence in the Wells Fargo case undermined Mitek’s
    assertion that it faced potential liability for infringement.
    The court explained: “The repeated testimony given during
    the Wells Fargo trial was that without significant
    can satisfy the more general all-the-circumstances test’ to
    establish jurisdiction.” (citation omitted)).

    customization by Wells Fargo, the Mitek Mi-Snap product
    does not infringe the asserted patent.” 
    Id.
     at 4–5. Seem-
    ingly on that basis, the court concluded that the Wells
    Fargo litigation did not contain implied accusations of in-
    fringement by Mitek and, in fact, “gave Mitek every reason
    to think that USAA does not intend to pursue any claim for
    patent infringement against Mitek.” 
    Id. at 4
    .
    This reasoning is not sufficiently complete to support
    the conclusion drawn. Determining whether Mitek reason-
    ably might be liable for infringement requires “look[ing] to
    the elements of the potential cause of action” and consider-
    ing both the patent claims at issue and the alleged facts
    concerning Mitek and its customers in light of those ele-
    ments. Microsoft, 755 F.3d at 903–05. Although Mitek is
    not obligated to prove, for jurisdictional purposes, that it
    infringes the patents-in-suit (which is what it ultimately
    seeks to disprove in the case), “there must be allegations by
    the patentee or other record evidence that establish at least
    a reasonable potential that [infringement claims against
    Mitek] could be brought.” Id. at 905. This requires sepa-
    rate consideration of the separate types of infringement
    (notably, direct infringement, inducement of infringement,
    and contributory infringement) of the claims of the patents-
    in-suit, and of the bearing on any infringement of such
    claims of the fact stressed by the district court—namely,
    that bank customers customize Mitek’s software.
    The district court did not conduct an analysis at this
    level of specificity. The district court’s reference to custom-
    ization does not identify the choices that Mitek’s customers
    make and tie those choices to the coverage of a claim; con-
    sequently, the reference does not show that, without the
    customer’s choices, Mitek’s product itself is not within the
    claim coverage. And even if customization is how a Mitek
    customer comes within a claim element, the need for such
    customization does not exclude Mitek liability for induce-
    ment under 
    35 U.S.C. § 271
    (b)—if, for example, Mitek pro-
    vides manuals, along with the software, that meet the

    standard of taking an affirmative act to encourage infringe-
    ment with the knowledge that the induced acts constitute
    patent infringement. Global-Tech Appliances, Inc. v. SEB
    S.A., 
    563 U.S. 754
    , 765–66 (2011); see, e.g., J.A. 720–22 (ev-
    idence potentially relevant to inducement). Analysis of
    that possibility appears to be needed. So too of any possi-
    bility of contributory infringement if MiSnap™ is not suit-
    able for substantial non-infringing uses.           
    35 U.S.C. § 271
    (c); see, e.g., J.A. 434–35, 566–67 (evidence potentially
    relevant to contributory infringement). Even direct in-
    fringement may warrant more analysis than is reflected in
    the district court’s opinion. See J.A. 31 (Compl. ¶ 12); see
    also J.A. 478. 4
    The required analysis also should be clear about
    whether the Rule 12(b)(1) motion is being treated as pre-
    senting a facial or a factual challenge and whether the pre-
    conditions for treating such a motion as a factual challenge
    were met. The district court, though seeming to recognize
    that facts were placed in dispute, was less than clear about
    this distinction. Compare Dismissal Order at 2 (implying
    in legal standard section that the court was going to decide
    the motion on the complaint alone, accepting as true the
    allegations and facts set forth therein), with 
    id.
     at 4–5
    (seemingly treating USAA’s motion to dismiss as a factual
    attack on whether USAA implicitly accused Mitek of in-
    fringement in the Wells Fargo litigation). It appears that
    USAA took the steps required to mount a factual attack
    that entitled it to a resolution of at least some factual dis-
    putes, not just to a decision on the sufficiency of the com-
    plaint when combined with undisputed facts. See J.A. 262–
    4  The parties have focused on claim 1 of the ’779 pa-
    tent on appeal, but oral argument suggested the possibility
    that it might not be fully representative for the direct, con-
    tributory, or induced infringement analysis. See Oral Arg.

    67 (USAA’s motion to dismiss, submitting evidence from
    Wells Fargo trial); J.A. 882–84 (USAA’s reply, specifically
    asserting that USAA’s motion was factual, not facial); J.A.
    957–1014 (argument to district court, discussing at length
    what was shown in the Wells Fargo trial). But we leave
    that determination to the district court in the first in-
    stance, as we do the determination whether either party
    forfeited any particular contention (about a particular type
    of infringement, for example) or right to present, or obtain
    discovery of, additional evidence.
    Also for possible consideration on remand, if not for-
    feited, are related issues concerning events and evidence
    that post-date the filing of this declaratory-judgment ac-
    tion on November 1, 2019. One such issue is whether, even
    if a case or controversy between USAA and Mitek existed
    on that day based on potential Mitek liability, it ceased to
    exist later—for example, once USAA and Wells Fargo had
    settled their case and USAA still had not sued Mitek even
    though it had sued another bank. Another issue is whether
    any case or controversy between USAA and Mitek as of No-
    vember 1, 2019, extended beyond the potential for Mitek
    liability involving Mitek’s dealings with Wells Fargo spe-
    cifically. Both of these issues, and perhaps others, might
    involve exploring the extent of similarities between Mitek’s
    relationships with Wells Fargo and other customers. 5
    In short, on remand, the district court’s primary task
    regarding Mitek’s first asserted basis for establishing a
    case or controversy will be to ascertain the alleged role of
    the Mitek technology in the banks’ applications and the al-
    leged role that the Mitek technology plays in infringement
    claims.      Making those core determinations, and
    5   Mitek has included in the record a news article con-
    taining statements attributed to USAA about “the banking
    industry.” J.A. 768–70. We do not decide what, if any, role
    that article has to play in this case.

    UNITED SERVICES AUTOMOBILE ASSOCIATION
    considering any other pertinent issues, will supply a fuller
    basis for the bottom-line assessment of Mitek’s first theory
    of Article III jurisdiction.
    2
    For similar reasons, the district court’s case-or-contro-
    versy analysis of USAA’s letters to Mitek customers com-
    bined with subsequent indemnification demands is
    inadequate. Concerning the letters specifically, the court
    stated that it was “not convinced that these letters create
    a justiciable controversy,” observing that Mitek had sub-
    mitted only one letter with the complaint—a letter that
    came from USAA’s licensing counsel and that did not
    threaten litigation, include claim charts for the patents-in-
    suit, or identify Mitek or particular products as infringing.
    Dismissal Order at 6–7. The court did not address the com-
    plaint’s allegations about indemnification requests from
    other Mitek customers who had received letters. 
    Id.
     at 7–
    8 (addressing indemnification only with respect to Wells
    Fargo and PNC).
    The first part of this two-part assertion is that the
    USAA letters to Mitek’s customers created an actual in-
    fringement controversy between USAA and those custom-
    ers that would have sufficed for those customers to seek
    declaratory relief. This is a necessary element of the as-
    serted indemnity-based interest of Mitek. See BP Chemi-
    cals Ltd. v. Union Carbide Corp., 
    4 F.3d 975
    , 981 (Fed. Cir.
    1993) (“The agreement to defend or indemnify a third per-
    son does not provide the actual controversy whereby the
    defender or indemnitor may bring a declaratory action on
    its own behalf when there is no actual controversy involv-
    ing the indemnitee.”). On this first part, we conclude that
    the allegations in Mitek’s complaint concerning USAA’s
    letter campaign and the attached example letter, viewed in
    light of the Wells Fargo litigation, are sufficient to show a
    Case: 21-1989     Document: 34       Page: 19     Filed: 05/20/2022

    UNITED SERVICES AUTOMOBILE ASSOCIATION
    controversy between USAA and Mitek’s customers who re-
    ceived letters. 6
    As we explained in Hewlett-Packard Co. v. Acceleron
    LLC, “declaratory judgment jurisdiction exists ‘where a pa-
    tentee asserts rights under a patent based on certain iden-
    tified ongoing or planned activity of another party, and
    where that party contends that it has the right to engage
    in the accused activity without license.’” 
    587 F.3d 1358
    ,
    1361 (Fed. Cir. 2009) (citation omitted). But “a communi-
    cation from a patent owner to another party, merely iden-
    tifying its patent and the other party’s product line,
    without more,” does not suffice. 
    Id. at 1362
    . Here, there is
    just enough “more.”
    The example letter attached to the complaint includes
    three of the four patents-in-suit (covering both relevant
    families) in its patent list, stating that “these are . . . likely
    to be relevant to your offering of a mobile check deposit ap-
    plication.” J.A. 45, 79–82 (Compl. Ex. A). Additionally, the
    letter provides a claim chart that, in addressing a different,
    unrelated patent, explains “in detail . . . how the claims re-
    late to the mobile deposit application offered by one of the
    largest banks in the US,” which USAA states it believes
    “operates in a similar way” to the deposit application of the
    letter recipient. J.A. 45 (Compl. Ex. A). Particularly in
    light of USAA’s recent litigation against Wells Fargo on the
    four patents-in-suit, which the customer would know was
    in part based on use of Mitek technology, see Micron
    6    We do not read USAA’s motion to dismiss as con-
    testing the facts concerning the USAA letters to Mitek’s
    customers. See J.A. 269–70. We therefore do not view the
    motion as presenting a factual challenge on this point, but
    only a facial challenge to the legal sufficiency of the com-
    plaint’s allegations to establish the letters half of its indem-
    nity-based argument for the existence of a case or
    controversy.

    Technology, Inc. v. Mosaid Technologies, Inc., 
    518 F.3d 897
    ,
    901–02 (Fed. Cir. 2008), we conclude that, under the total-
    ity of the circumstances, there is enough for Mitek’s other
    customers to reasonably interpret USAA’s actions as an
    implicit assertion of infringement based on incorporation
    of Mitek technology, Hewlett-Packard, 
    587 F.3d at 1363
    .
    The second half of Mitek’s indemnity-based assertion
    of a case or controversy concerns whether, beyond bare in-
    demnity demands or requests, there was actually a “rea-
    sonable potential” of Mitek’s indemnification liability, with
    that potential giving Mitek the required concrete stake in
    litigating the underlying customers’ freedom from infringe-
    ment liability to USAA. See Microsoft, 755 F.3d at 905. We
    have sometimes used the language of “obligation” when re-
    ferring to the indemnity issue in this context. See, e.g., id.
    at 904; Arris, 
    639 F.3d at 1375
    ; Allied Mineral Products,
    Inc. v. OSMI, Inc., 
    870 F.3d 1337
    , 1340–41 (Fed. Cir. 2017).
    But we have never held that the validity of an indemnity
    demand, i.e., the applicability of an indemnity agreement
    to the demander’s circumstances, needs to be conceded to
    establish subject-matter jurisdiction. Indeed, other cases,
    such as Microchip Technology Inc. v. Chamberlain Group,
    Inc., refer only to the “existence of an indemnity agree-
    ment,” not its conceded applicability in the particular case.
    
    441 F.3d 936
    , 943 (Fed. Cir. 2006); see also Creative Com-
    pounds, LLC v. Starmark Laboratories, 
    651 F.3d 1303
    ,
    1316 (Fed. Cir. 2011). Similarly, Microsoft suggests that
    only the “merit of the customer request” is relevant, which
    does not require a concession of the request’s validity. 755
    F.3d at 904. And such a concession is not required to es-
    tablish that the declaratory-judgment plaintiff (receiving
    indemnity demands) has a definite, concrete, immediate,
    real interest in obtaining the declaration sought.
    What remains is a need for further proceedings on re-
    mand. The district court should first determine which Rule
    12(b)(1) framework to apply, i.e., determine whether USAA
    mounted a factual attack on the indemnity allegations of
    Case: 21-1989    Document: 34      Page: 21   Filed: 05/20/2022
    MITEK SYSTEMS, INC. v.                                   21
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    Mitek’s complaint. See, e.g., J.A. 267–68, 270–71 (USAA
    motion to dismiss); J.A. 883, 885 (USAA reply); J.A. 360,
    899 (evidence regarding Wells Fargo indemnification, po-
    tentially conflicting with allegations in the complaint, see
    J.A. 31–32 (Compl. ¶ 13)). If it finds that USAA has not
    mounted a factual attack, the court must closely analyze
    the relevant indemnity allegations, J.A. 31–32 (Compl.
    ¶ 13), to determine whether they suffice. If it finds that
    USAA has mounted a factual attack, we again leave it to
    the district court to decide how to proceed, including
    whether the parties should have the opportunity to present
    additional evidence, and to address (at least for purposes
    of continuing jurisdiction) issues concerning post-com-
    plaint events, such as USAA’s suit against PNC and PNC’s
    indemnification request to Mitek through a third party,
    J.A. 1035–36. The character of the indemnity demands re-
    ceived and the precise scope of the corresponding indem-
    nity agreements, see Oral Arg. at 33:20–34:25; Mitek Reply
    Br. 17 n.4, may bear heavily on the sufficiency of Mitek’s
    indemnity-based interest in obtaining the requested de-
    claratory judgment that can be sought based on that inter-
    est—namely, a declaration of its customer’s nonliability
    because of noninfringement or invalidity of the patents at
    issue.

    The court stated that, in case its “determination that
    subject matter jurisdiction is lacking were later set aside,
    [it] would similarly and for the same reasons exercise its
    discretion and decline to exercise jurisdiction over Mitek’s
    declaratory judgment action.” Dismissal Order at 8–9. We
    review a district court’s discretionary decision to dismiss
    for abuse of discretion. Communications Test Design, Inc.
    v. Contec, LLC, 
    952 F.3d 1356
    , 1361 (Fed. Cir. 2020).
    Where a discretionary decision rests on an inadequate ex-
    planation and might well be different without the deficien-
    cies, we may vacate the decision and remand for
    reconsideration. See, e.g., Whitserve, LLC v. Computer
    Case: 21-1989    Document: 34      Page: 22    Filed: 05/20/2022
    22                                   MITEK SYSTEMS, INC. v.
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    Packages, Inc., 
    694 F.3d 10
    , 35–36 (Fed. Cir. 2012). We
    follow that course regarding the discretion ruling here.
    Given the Declaratory Judgment Act’s use of the word
    “may,” 
    28 U.S.C. § 2201
    (a), the Supreme Court has stated
    that a district court has “unique and substantial discretion
    in deciding whether to declare the rights of litigants,” Wil-
    ton v. Seven Falls Co., 
    515 U.S. 277
    , 286 (1995) (quoted
    with approval in MedImmune, 
    549 U.S. at 136
    ). The Court
    likewise has said that “facts bearing on the usefulness of
    the declaratory judgment remedy, and the fitness of the
    case for resolution, are peculiarly within [district courts’]
    grasp.” Id. at 289 (again quoted with approval in MedIm-
    mune, 
    549 U.S. at 136
    ). The scope of the discretion remains
    unclear. In Wilton, the Court “conclude[d] only that the
    District Court acted within its bounds in staying [an] ac-
    tion for declaratory relief where parallel proceedings, pre-
    senting opportunity for ventilation of the same state law
    issues, were underway in state court.” Id. at 290.
    For our part, we have said that, as long as a district
    court “acts in accordance with the purposes of the Declara-
    tory Judgment Act and the principles of sound judicial ad-
    ministration, [it] has broad discretion to refuse to entertain
    a declaratory judgment action.” EMC Corp. v. Norand
    Corp., 
    89 F.3d 807
    , 813–14 (Fed. Cir. 1996). But, consistent
    with the constraints imposed by the noted statutory pur-
    poses and judicial-administration principles, we have in-
    sisted: “There must be well-founded reasons for declining
    to entertain a declaratory judgment action.” Capo, Inc. v.
    Dioptics Medical Products, 
    387 F.3d 1352
    , 1355 (Fed. Cir.
    2004); see also Micron, 
    518 F.3d at
    903–05; Genentech, Inc.
    v. Eli Lilly & Co., 
    998 F.2d 931
    , 936 (Fed. Cir. 1993). As
    an example, we explained in Ford Motor Co. v. United
    States that, “[w]hile the existence of another adequate rem-
    edy does not necessarily bar a declaratory judgment, dis-
    trict courts may refuse declaratory relief where an
    alternative remedy is better or more effective.” 
    811 F.3d 1371
    , 1379–80 (Fed. Cir. 2016) (citations omitted); see also
    Case: 21-1989    Document: 34       Page: 23    Filed: 05/20/2022

    UNITED SERVICES AUTOMOBILE ASSOCIATION
    10B Wright & Miller § 2758 & n.6 (4th ed. Apr. 2022 Up-
    date).
    Here, the district court did not give reasons independ-
    ent of its reasons for its jurisdictional dismissal, which we
    have held above to be deficient in various respects. With-
    out further analysis of why those reasons make it appro-
    priate to decline to entertain the claim for declaratory relief
    as a matter of discretion when we have determined that the
    same reasons do not support the jurisdictional dismissal
    (at least at this stage of the proceedings), the district
    court’s discretion ruling cannot stand. We note in particu-
    lar that the district court may have been suggesting that
    the route of intervention in one or more USAA suits against
    Mitek customers is preferable, considering statutory pur-
    poses and judicial-administration principles, to the declar-
    atory-judgment action Mitek initiated here. See Mitek
    Opening Br. 32 (so reading the district court opinion);
    USAA Response Br. 45 (same). If so, a determination along
    those lines would require more analysis of various issues,
    such as (but not necessarily limited to): (1) whether Mitek
    could intervene in such actions and under what circum-
    stances, (2) whether intervention would provide Mitek ad-
    equate relief from the harms the Declaratory Judgment
    Act recognizes as a basis for such relief, (3) the scope of
    what would have to be adjudicated in Mitek’s suit for a dec-
    laration of noninfringement on behalf of Mitek and all of
    its customers and whether that scope could properly be lim-
    ited to address unwieldiness, and (4) whether ultimately
    the intervention route is more effective or efficient than the
    declaratory-judgment route.
    We vacate the discretionary dismissal.

    Mitek argues that, if we disturb the dismissal and re-
    mand (as we are doing), we should order the case to be
    transferred on remand back to the Northern District of Cal-
    ifornia because the original order transferring the case to
    Case: 21-1989    Document: 34      Page: 24    Filed: 05/20/2022
    24                                   MITEK SYSTEMS, INC. v.
    UNITED SERVICES AUTOMOBILE ASSOCIATION
    the Eastern District of Texas should be reversed.         See
    Mitek Reply Br. 25. We reject that argument.
    A
    As an initial matter, Fifth Circuit law appears to pre-
    clude Mitek from successfully challenging the transfer or-
    der in the present appeal, taken after final judgment. The
    Fifth Circuit has held that “mandamus is the prescribed
    vehicle for reviewing rulings on transfers of cases pursuant
    to 
    28 U.S.C. § 1404
    (a).” Defense Distributed v. Bruck, 
    30 F.4th 414
    , 423 (5th Cir. 2022) (citing In re Volkswagen of
    America, Inc., 
    545 F.3d 304
    , 309 (5th Cir. 2008) (en banc),
    and In re Rolls Royce Corp., 
    775 F.3d 671
    , 676–77 (5th Cir.
    2014)). As we have recognized, a key part of the Fifth Cir-
    cuit’s assessment is the conclusion that a party seeking to
    challenge a § 1404(a) transfer decision cannot succeed on
    an appeal from an adverse final judgment because the
    party “would not be able to show that it would have won
    the case had it been tried in a convenient forum,” as is re-
    quired by 
    28 U.S.C. § 2111
     and Federal Rule of Civil Pro-
    cedure 61. In re HTC Corp., 
    889 F.3d 1349
    , 1352 n.5 (Fed.
    Cir. 2018) (citation omitted). To the extent that those prec-
    edents establish a rule of law precluding success in chal-
    lenging a § 1404(a) transfer on a final-judgment appeal, or
    simply insist on a showing that the transfer was prejudicial
    regarding the merits of the judgment appealed, we must
    reject Mitek’s challenge regarding transfer here.
    After USAA pointed out this case law, Mitek declined
    to present a developed or persuasive reply. See Mitek Re-
    ply Br. 20–22. 7 Mitek cited (1) a Fifth Circuit decision, not
    7  Mitek primarily responded to USAA’s separate and
    alternative argument that Mitek forfeited review of the
    transfer order by not moving in the Texas forum to retrans-
    fer. See USAA Response Br. 49–50. We need not reach
    that issue.

    involving transfer, recognizing that “generally, ‘a party
    may obtain review of prejudicial adverse interlocutory rul-
    ings upon his appeal from adverse final judgment,’” Diece-
    Lisa Industries, Inc. v. Disney Enterprises, Inc., 
    943 F.3d 239
    , 247 (5th Cir. 2019) (citation omitted); (2) a decision of
    a different circuit (the Second), indicating that “[t]he fail-
    ure to seek mandamus review of an interlocutory [transfer]
    ruling does not forfeit the opportunity to obtain review on
    appeal from a final judgment,” but not repudiating the
    prejudice requirement, SongByrd, Inc. v. Estate of Gross-
    man, 
    206 F.3d 172
    , 176–177 (2d Cir. 2000); and (3) a prac-
    tice guide that adds no supporting authority, The Rutter
    Group, Federal Civil Procedure Before Trial, National Edi-
    tion, Ch. 4-K, § 6.b.[4:809] (Apr. 2021 Update). This re-
    sponse does not dispute the content of Fifth Circuit law or
    make a showing that the transfer order here, even if wrong,
    was in fact prejudicial.
    B
    In any event, Mitek has not demonstrated an abuse of
    discretion—e.g., legal error, unreasonableness, clear fac-
    tual error—in the transfer order issued by the California
    district court. Sparling v. Hoffman Construction Co., 
    864 F.2d 635
    , 639 (9th Cir. 1988); see also In re Nissim Corp.,
    316 F. App’x 991, 992 (Fed. Cir. 2008) (non-precedential).
    First, we see no such abuse regarding the court’s assess-
    ment and weighing of the location of USAA’s licensing
    counsel (Epicenter Law) in the Northern District of Cali-
    fornia, Mitek’s location in a different district within Cali-
    fornia, and Mitek’s choice of forum. Transfer Order, 
    2020 WL 1922635
    , at *4–5. Mitek’s cited authorities are, at a
    minimum, not sufficiently on point to undermine the Cali-
    fornia court’s conclusions on these matters. See Neelon v.
    Bharti, 596 F. App’x 532, 533 (9th Cir. 2014) (non-prece-
    dential) (discussing a “heavy burden of proof” to overcome
    a plaintiff’s choice of forum and dismiss on forum non con-
    veniens grounds); Avocent Huntsville Corp. v. Aten Int’l
    Co., 
    552 F.3d 1324
    , 1336 (Fed. Cir. 2008) (focusing on
    Case: 21-1989    Document: 34      Page: 26    Filed: 05/20/2022

    UNITED SERVICES AUTOMOBILE ASSOCIATION
    enforcement activities for the purposes of determining per-
    sonal jurisdiction over a declaratory-judgment defendant);
    Sportsman for Sportsman v. California Overland, Ltd.,
    No. 17-1064, 
    2018 WL 1865930
    , at *5 (D. Minn. Apr. 18,
    2018) (analyzing forum shopping in the conflict-of-law con-
    text).
    Next, concerning the convenience-of-witnesses compo-
    nent of the transfer analysis, Mitek contends that the most
    critical witnesses are Mitek witnesses who are likely to be
    located near its headquarters in the Southern District of
    California. See Mitek Opening Br. 39–41. We see no abuse
    of discretion, however, in the court’s deeming USAA’s po-
    tential witnesses also to be critical and determining that
    this factor was neutral. See Transfer Order, 
    2020 WL 1922635
    , at *5.
    Finally, Mitek argues that the Wells Fargo litigation
    should not have supported transfer. Mitek Opening Br.
    38–39; see also Transfer Order, 
    2020 WL 1922635
    , at *5.
    But it is not an abuse of discretion to consider the fact that
    the Eastern District of Texas was already familiar with the
    patents and technology. See In re Apple Inc., 
    979 F.3d 1332
    , 1344 (Fed. Cir. 2020); see also In re Eli Lilly & Co.,
    541 F. App’x 993, 994 (Fed. Cir. 2013) (non-precedential).
    To be sure, that consideration might be so clearly out-
    weighed by other considerations that it cannot support de-
    nial of transfer to a “far more convenient” venue, as we
    have recognized. See In re Morgan Stanley, 417 F. App’x
    947, 949–50 (Fed. Cir. 2011) (non-precedential) (discussing
    In re Zimmer Holdings, Inc., 
    609 F.3d 1378
     (Fed. Cir.
    2010), and In re Verizon, 
    635 F.3d 559
     (Fed. Cir. 2011)).
    But here, as already discussed, it was reasonable for the
    court to find that the Northern District of California was
    not far more convenient than the Eastern District of
    Texas—and thus to transfer on the basis of judicial econ-
    omy, as no other factors favored retaining the action.

    For the foregoing reasons, we vacate the district court’s
    dismissal for lack of subject-matter jurisdiction, as well as
    its alternative discretionary dismissal, and remand to the
    Eastern District of Texas for further proceedings consistent
    with this opinion.
    The parties shall bear their own costs.
