    TORRUELLA,   Circuit      Judge.        Petitioner-Appellant
    George W. Schlich, a patent agent for Intellia Therapeutics, Inc.,
    appeals   from    the   district   court's   denial   of   a   petition   for
    discovery under 28 U.S.C. § 1782.          That statute allows a party to
    file a petition in district court to obtain discovery for use in
    a   foreign    proceeding. 1    Here,   Schlich   sought   discovery      from
    Respondents-Appellees The Broad Institute, Inc., Dr. Feng Zhang,
    Dr. Naomi Habib, and Dr. Le Cong (collectively, "Broad") in
    relation to opposition proceedings currently before the European
    Patent Office ("EPO").2        In the opposition proceedings, Schlich
    challenges the validity of several of Broad's European patents
    involving CRISPR-Cas9 technology used in the programmable genome
    editing of mammalian cells.          Schlich contends that the district
    1   28 U.S.C. § 1782(a) provides in pertinent part:
    The district court of the district in which a person
    resides or is found may order him to give his testimony
    or statement or to produce a document or other thing for
    use in a proceeding in a foreign or international
    tribunal, including criminal investigations conducted
    before formal accusation. The order may be made pursuant
    to a letter rogatory issued, or request made, by a
    foreign   or   international   tribunal  or   upon   the
    application of any interested person and may direct that
    the testimony or statement be given, or the document or
    other thing be produced, before a person appointed by
    the court.
    2  An opposition proceeding before the EPO "allows any member of
    the public to challenge a European patent within nine months of
    its grant."
    -2-
    court erred in requiring him to prove the EPO's receptivity to the
    district court's assistance in providing the requested discovery,
    and in denying the request for discovery under § 1782 for lack of
    relevance to the foreign proceeding.        After careful consideration,
    we affirm.
    I.   Background
    A. Factual Background
    The   Broad   Institute,    Inc.   is   a   nonprofit   medical
    research organization founded in 2003 by Eli and Edythe Broad,
    alongside Harvard University, Harvard-affiliated hospitals, and
    the Massachusetts Institute of Technology.           The nonprofit launched
    in 2004, focusing on the development of genomic research for the
    advancement of medical science.         Dr. Feng Zhang is a member of the
    Broad Institute, and both Dr. Naomi Habib and Dr. Le Cong are
    Postdoctoral Associates who worked with Dr. Zhang.               Dr. Zhang
    dedicates part of his research to the CRISPR-Cas9 system for genome
    editing.
    Intellia is a "genome editing company" whose primary
    focus is the development of "potentially curative therapeutics"
    using the CRISPR-Cas9 system.             Schlich is a European patent
    attorney providing legal services to Intellia in the EPO opposition
    proceedings against four of Broad's patents related to CRISPR-
    Cas9.   Dr. Jennifer Doudna is a founding member of Intellia, and
    -3-
    the   company   holds       an   exclusive   license   to     Dr. Doudna's
    intellectual property in the CRISPR-Cas9 therapeutics field.
    The CRISPR-Cas9 system emerged from research on certain
    bacteria that can precisely target and "carve up" genetic material.
    When applied to human DNA, the potential curative value of this
    technology is allegedly tremendous, and its potential worth is
    estimated to be in the billions of dollars.
    Dr. Doudna and Dr. Emmanuelle Charpentier led a team
    working on the bacteria associated with the CRISPR-Cas9 technology
    and, on May 25, 2012, filed a provisional patent application3 at
    the United States Patent and Trademark Office ("U.S.P.T.O.") for
    certain   "methods    and    compositions"   for   "DNA     modification."
    Additionally, they published an article describing their findings
    in June 2012.   See Martin Jinek et al., A Programmable Dual-RNA-
    Guided DNA Endonuclease in Adaptive Bacterial Immunity, 337(6096)
    Science 816 (2012).
    3  A provisional patent application "serves as a placeholder with
    the [U.S.P.T.O.] that grants the applicant 'the benefit of
    priority' for an invention," United States v. Camick, 
    796 F.3d 1206
    , 1218 (10th Cir. 2015) (quoting U.S. Patent & Trademark
    Office, Manual of Patent Examination Procedure § 201.04 (9th ed.
    2014)), if the applicant subsequently files a non-provisional
    application within a certain period of time, see Chinsammy v.
    United States, 
    417 F. App'x 950
    , 951 (Fed. Cir. 2011) (citing
    35 U.S.C. §§ 119, 154).
    -4-
    On October 5, 2012, Dr. Zhang and other members of the
    Broad team, including Dr. Habib and Dr. Le Cong, submitted a
    manuscript that "reported the first successful programmable genome
    editing of mammalian cells using CRISPR-Cas9."            On December 12,
    2012, Broad filed its first provisional patent application with
    the U.S.P.T.O. relating to genomic sequence manipulation, and
    subsequently   filed    several    other    related   provisional   patent
    applications in the following months.
    Based on two provisional patent applications filed by
    Broad in December 2012 and January 2013, Thomas Kowalski, a U.S.
    Patent   Attorney,     filed   a   Patent   Cooperation   Treaty    ("PCT")
    application4 on behalf of Broad.       Since Broad's provisional patent
    applications included various inventions, Kowalski and Dr. Smitha
    Uthaman conducted an inventorship study to determine the different
    inventions and the corresponding contributions from each inventor.
    Subsequently, Broad filed ten separate PCT applications.               The
    subject matter of the initial provisional patent applications was
    divided among these PCT applications listing different inventors
    and a "divided priority" based on the findings of the inventorship
    4   A PCT application, also known as an international patent
    application, allows an applicant to simultaneously seek protection
    for an invention in over 150 countries. See World Intellectual
    Prop. Org., http://www.wipo.int/pct/en/ (last visited June 8,
    2018).
    -5-
    study.     Eventually, the PCT applications resulted in several
    European patents, which Intellia now challenges at the EPO.
    Schlich   filed    oppositions   with     the    EPO   seeking   the
    revocation of four of Broad's European patents.            At the opposition
    proceedings, Schlich argued, among other things, that Broad's
    European   patents   cannot    claim   right    of   priority     to   Broad's
    provisional patent applications filed with the U.S.P.T.O. because
    the applicants listed in the latter are not the same as those
    listed in the subsequent PCT applications, as is required by
    European patent law.    In response, Broad argued that United States
    law, and not European law, should determine whether its European
    patents can claim priority to the provisional applications because
    those provisional patent applications were filed in the United
    States.    According to Broad, United States law allows multiple
    inventions to be disclosed and multiple inventors to be listed in
    a provisional application without requiring that every inventor
    have contributed to every invention.           The right of priority from
    that provisional application could then be severed into different
    PCT applications without requiring complete identity between the
    inventors listed in both applications, as long as the applicant
    "claim[s] priority in [the PCT] application with regard to an
    invention to which [he or she] contributed."               In support of its
    contention that the proper procedure was followed here, Broad
    -6-
    submitted a declaration from Kowalski describing the process he
    followed and the findings of his inventorship study.
    B. Procedural History
    In September 2016, Schlich filed an application for
    discovery under 28 U.S.C. § 1782 in the United States District
    Court for the District of Massachusetts.           Schlich sought documents
    and testimony from Broad.            The discovery sought focused on the
    inventorship study conducted by Kowalski and Dr. Uthaman, as well
    as the assignment of the relevant rights over the corresponding
    inventions.        Broad opposed discovery and a hearing was held on
    October 24, 2016.          At the hearing, the parties disputed, among
    other things, whether the discovery sought was relevant to the EPO
    proceedings and whether the EPO would be receptive to the requested
    discovery.        Broad informed Schlich and the court that it would
    submit a request to the EPO to confirm "that the EPO is not
    receptive to the discovery sought by [] Schlich."             Broad filed the
    request on October 31, 2016.
    On    November   1,     2016,   the   district   court   ordered
    supplemental       briefing   after   noting   that   the   parties   had   not
    addressed the issue of the EPO's receptivity to the district
    court's assistance in providing the requested discovery prior to
    the   hearing. 5     The   parties    then   submitted   their   supplemental
    5   The supplemental briefing order directed the parties to address
    -7-
    briefs.         Broad's submission included a declaration from a former
    EPO official, who stated that the issue presented by Schlich in
    his § 1782 application "is a potential dispute over inventorship"
    or "entitlement," yet, "the EPO has no authority or jurisdiction
    to resolve issues of entitlement," including "whether inventorship
    is   or    is     not   correct."       The   declarant     thus   concluded       that
    "discovery relating to this issue would not be considered relevant
    and therefore would not be considered by the EPO."                  On December 9,
    2016,     the     district     court    denied    Schlich's      petition     without
    prejudice.        In re Schlich, 
    2016 WL 7209565
    (D. Mass. Dec. 9, 2016).
    It found that three of the four statutory requirements of § 1782
    were met -- including that the discovery be "for use" in a foreign
    proceeding        --    and   assumed   without       deciding   that   the    fourth
    requirement was also satisfied.                  
    Id. at *3.
           The court then
    considered the factors established by the Supreme Court in Intel
    Corp. v. Advanced Micro Devices, Inc., 
    542 U.S. 241
    (2004) (the
    Intel factors) and concluded, inter alia, that "because the EPO
    will      not    make    a    determination      as    to   inventorship      in   the
    [o]pposition proceeding[s]," Schlich had not demonstrated that the
    the EPO's receptivity issue, including the following questions:
    "(1) why the Kowalski affidavit was submitted to the EPO,
    (2) whether the EPO has authority or jurisdiction to resolve issues
    of inventorship in the pending proceeding, and (3) if it does not
    have such authority or jurisdiction, how the EPO would be receptive
    to this Court's assistance in providing the requested discovery."
    -8-
    discovery sought was "relevant" to the opposition proceedings and
    thus had "failed to show that the EPO would be receptive to the
    Court's assistance."         In re Schlich, 
    2016 WL 7209565
    at *6.
    Relying heavily on this reasoning, the court denied Schlich's
    petition, but clarified that if it became clear that the EPO would
    be receptive to the assistance of the court, or if fairness
    otherwise required that the decision be reconsidered, Schlich
    could renew his petition.       
    Id. at *7.
    On March 15, 2017, the district court denied Schlich's
    Motion for Reconsideration.           Schlich timely appealed.          Shortly
    after the notice of appeal was filed, the EPO issued a preliminary
    and   non-binding   opinion     and    summoned     the    parties    for   oral
    proceedings.
    II.     Discussion
    A. Standard of Review
    Because § 1782 is a mechanism for obtaining discovery,
    and "[t]he trial court is in the best position to weigh fairly the
    competing needs and interests of parties affected by discovery,"
    Seattle   Times   Co.   v.   Rhinehart,      
    467 U.S. 20
    ,   36   (1984),   we
    generally review the grant or denial of a discovery request under
    § 1782 for abuse of discretion, In re Asta Medica, S.A., 
    981 F.2d 1
    , 4 (1st Cir. 1992), abrogated on other grounds by Intel 
    Corp., 542 U.S. at 259-61
    .     However, if the district court's decision is
    -9-
    based on an interpretation of the law, we review it de novo.
    See Santiago-Sepúlveda v. Esso Standard Oil Co. (P.R.), 
    643 F.3d 1
    ,   4   (1st   Cir.   2011);   see     also   Consorcio   Ecuatoriano      de
    Telecomunicaciones S.A. v. JAS Forwarding (USA), Inc., 
    747 F.3d 1262
    , 1268 (11th Cir. 2014); In re Bayer AG, 
    146 F.3d 188
    , 191 (3d
    Cir. 1998).
    B. Section 1782(a)'s statutory requirements and the Intel factors
    Today's § 1782 is the product of over 150 years of
    Congressional effort and manifests the intent to provide "federal-
    court    assistance    in   gathering    evidence   for    use   in    foreign
    tribunals."     Intel 
    Corp., 542 U.S. at 247
    .         The text of § 1782
    provides that granting discovery is proper only if: 1) the person
    from whom discovery is sought "resides or is found" in the district
    where the court sits; 2) the request seeks evidence (the "testimony
    or statement" of a person or the production of a "document or other
    thing") "for use in a proceeding in a foreign or international
    tribunal"; 3) the request is made by a foreign or international
    tribunal or by "any interested person"; and 4) the material sought
    is not protected by "any legally applicable privilege."6              28 U.S.C.
    6  We note that although the district court and the parties all
    make reference to these four requirements as the "statutory
    requirements" of § 1782, some circuits only consider the first
    three of these as statutory requirements.      See, e.g., Certain
    Funds, Accounts and/or Inv. Vehicles v. KPMG, L.L.P., 
    798 F.3d 113
    , 117 (2d Cir. 2015). We do not delve into this because it has
    not been raised by the parties and, in any event, the statute does
    -10-
    § 1782(a).   If all of these statutory requirements are met, the
    district court is authorized, but not required, to provide judicial
    assistance by permitting discovery. Intel 
    Corp., 542 U.S. at 247
    ;
    see 28 U.S.C. § 1782(a) ("The district court . . . may order
    . . . .") (emphasis added).
    The district court's discretion to allow discovery if
    all § 1782 requirements are met is not boundless.   Rather, district
    courts must exercise their discretion under § 1782 in light of the
    twin aims of the statute: "providing efficient assistance to
    participants in international litigation and encouraging foreign
    countries by example to provide similar assistance to our courts."
    Intel 
    Corp., 542 U.S. at 252
    (quoting Advanced Micro Devices, Inc.
    v. Intel Corp., 
    292 F.3d 664
    , 669 (9th Cir. 2002)).       The Supreme
    Court has identified four discretionary factors that also "bear
    consideration" in arriving at a decision.   
    Id. at 264.
        The first
    factor to consider is whether the person from whom discovery is
    sought is a party to the foreign proceeding, in which case "the
    need for § 1782(a) aid generally is not as apparent" because a
    "foreign tribunal has jurisdiction over those appearing before it,
    and can itself order them to produce evidence."     
    Id. The second
    prohibit compelling a person "to give his testimony or statement
    or to produce a document or other thing in violation of any legally
    applicable privilege." 28 U.S.C. §1782(a).
    -11-
    factor, at issue here, was adopted from a Senate Report explaining
    that a court "may take into account the nature of the foreign
    tribunal, the character of the proceedings underway abroad, and
    the receptivity of the foreign government or the court or agency
    abroad to U.S. federal-court judicial assistance."                   
    Id. (citing S.
    Rep. No. 88-1580, at 7 (1964), as reprinted in 1964 U.S.C.C.A.N.
    3782, 3788 (hereinafter "Senate Report")).                The third factor to
    consider is whether the request "conceals an attempt to circumvent
    foreign    proof-gathering       restrictions      or    other    policies   of   a
    foreign country or the United States."              
    Id. at 265.
        Finally, the
    fourth factor addresses whether the request is "unduly intrusive
    or burdensome" to the extent that it should either be "trimmed" or
    rejected outright.         
    Id. In sum,
    a district court must first
    determine whether the statutory requirements are met.                     If they
    are, the district court should then consider the four discretionary
    factors before arriving at a decision.
    C. The district court's decision
    Here,   the    district      court     addressed     the    statutory
    requirements and the discretionary Intel factors before arriving
    at   its   decision.       It    found    that    the   first    three   statutory
    requirements were met, and assumed without deciding that the fourth
    requirement was also satisfied.             In re Schlich, 
    2016 WL 7209565
    at *6.     Specifically as to the "for use" requirement, the district
    -12-
    court noted as "undisputed" that "the material is requested for
    use in a pending [o]pposition proceeding before the EPO."           
    Id. at *3.
        It then considered the Intel factors.           The district court
    found that the last two Intel factors weighed in favor of granting
    the discovery request because the request was "not obviously
    frivolous" nor appeared to be pursued for "improper means," and
    because Broad "d[id] not contend that all of the information sought
    [was] confidential or would be damaging if revealed" and, in any
    event, the court could "narrowly tailor[]" the request and issue
    protective orders.     
    Id. at *6-7.
         The district court, however,
    found that the first two discretionary factors weighed in favor of
    denying the petition.      
    Id. at *4-5.
        Regarding the first Intel
    factor, the district court noted that Broad is a party in the
    foreign proceeding and, although Drs. Zhang, Habib, and Le Cong
    were not named parties, "the information sought from them relates
    to their employment with Broad" and "appears to come within the
    EPO's jurisdiction."      
    Id. at *4-5.
        With respect to the second
    discretionary   factor,   the   court    noted   that    "[t]he   requested
    discovery relates to the issue of inventorship," yet inventorship
    determinations or disputes regarding inventorship seemed to be out
    of the jurisdiction of the EPO in opposition proceedings.           
    Id. at *5-6.
       The court also noted that Schlich had not shown that the
    -13-
    requested discovery was relevant to the foreign proceeding.7                       
    Id. at *6.
        After considering and balancing all of the Intel factors,
    the court denied the petition, primarily because it did not appear
    that the foreign tribunal would be "receptive to the assistance of
    the [c]ourt in providing discovery."              
    Id. at *7.
    Both parties agree that the only issue on appeal is the
    district    court's    interpretation        of   the    second    Intel    factor.
    Specifically,       Schlich     argues    that,     as    the     party    opposing
    discovery, Broad should have borne the burden of establishing, by
    authoritative    proof, 8 that      the   foreign       tribunal   would     not   be
    receptive to the discovery sought.                He further claims that the
    district    court    erroneously    inverted       the   burden    of     proof    and
    required him to provide authoritative proof that the foreign
    tribunal would be receptive to the assistance of the court in
    obtaining discovery.          Had the district court properly placed the
    burden of proof on Broad, Schlich's argument goes, it would have
    granted the discovery request because "Broad had not definitively
    7  The court's memorandum and order stated that "Broad" had not
    demonstrated that the discovery sought was relevant, but it is
    evident that the court was referring to "Schlich." 
    Id. at *6.
    8  "Authoritative proof" has been defined as proof that provides
    "clear directive" of something, such as proof "embodied in a forum
    country's judicial, executive or legislative declarations."
    Euromepa S.A. v. R. Esmerian, Inc., 
    51 F.3d 1095
    , 1100 (2d Cir.
    1995).
    -14-
    and conclusively shown by authoritative proof or otherwise that
    the EPO would not be receptive to the discovery."
    Broad urges us to find Schlich's arguments on appeal
    waived.    It argues that Schlich did not argue below that Broad
    bore the burden to demonstrate that the EPO would be unreceptive
    to the requested discovery, "let alone that Broad was required to
    submit    'authoritative    proof'   of     the    EPO's    position."        Broad
    further argues that Schlich's arguments also fail on the merits
    because although Schlich -- as the "party seeking relief" -- did
    have the burden to prove the elements of his claim, the district
    court never placed the burden on Schlich to provide "'authoritative
    proof' of the EPO's receptivity -- indeed, that standard appears
    nowhere in the district court's decision."               Instead, Broad posits,
    the   district   court's    determination         "was    based    on    undisputed
    evidence submitted by Broad" showing that the requested discovery
    was irrelevant to the foreign proceedings "and thus did not turn
    on the burden of proof."     We first address Broad's waiver argument.
    Because   we   conclude    that   Schlich's       arguments       were   adequately
    preserved, we then turn to the merits of his arguments.
    D. The arguments were adequately preserved
    Broad acknowledges that Schlich addressed the "differing
    views" regarding who bore the burden of proof, but claims that he
    "did not take a position as to which view was correct" and,
    -15-
    instead, argued in the district court that, under any of these
    views, the second Intel factor weighed in favor of granting the
    requested discovery.       Broad further argues that Schlich did not
    develop    the   legal   standard    argument   below.   In     consequence,
    according to Broad, Schlich has waived the arguments he now makes
    on appeal.
    We find the issues adequately preserved below.         Schlich
    raised the burden of proof argument in the district court, both in
    his writings prior to the hearing and at the hearing.            On several
    occasions, Schlich recognized that the First Circuit has yet to
    determine the issue, but argued that Broad, as a respondent
    opposing     discovery,     should     prove    the   foreign    tribunal's
    unreceptivity.     See, e.g., ECF No. 27, Transcript of Hearing at 14
    ("[O]nce you show that the discovery is relevant . . . then the
    burden shifts to the opposing party, to Broad, to demonstrate that
    the petition should not be granted."); 
    id. at 18
    ("[S]everal . . .
    other courts . . . presume that the foreign tribunal will accept
    the evidence unless the respondents prove otherwise, in other
    words, the burden is on the other side to prove that the Court
    won't be receptive."). Furthermore, Schlich sufficiently developed
    his legal standard argument by referencing other courts applying
    that same standard, and by further characterizing his evidence as
    meeting that standard.       See ECF No. 22 at 5 (stating that while
    -16-
    "Broad    failed       to   offer     any    evidence     that    the    EPO   would   be
    unreceptive to the requested discovery, [Schlich] has offered
    authoritative          evidence      to     the     contrary")    (emphasis     added).
    Therefore, the issues were adequately preserved.                        We thus address
    the merits of Schlich's arguments.
    E. Merits
    The Supreme Court has not established the appropriate
    burden of proof, if any, for any of the discretionary factors, or
    the legal standard required to meet that burden.                          Intel 
    Corp., 542 U.S. at 264-65
    ;    see    Certain        Funds,    Accounts    and/or   Inv.
    Vehicles v. KPMG, L.L.P., 
    798 F.3d 113
    , 118 (2d Cir. 2015) (noting
    that     the    Intel       opinion       lacks     guidance     regarding     "minimum
    requirements or tests to be met").
    It is undisputed that Schlich, as the party seeking
    discovery under § 1782, had the burden of establishing that all
    the statutory requirements were met in order for the court to even
    consider exercising its discretion to grant the requested relief.
    See, e.g., Certain Funds, Accounts and/or Inv. 
    Vehicles, 798 F.3d at 120
    (burden on movant to establish the statutory requirements);
    Consorcio Ecuatoriano de Telecomunicaciones 
    S.A., 747 F.3d at 1271
    (implying       that    the    movant       must     "satisf[y]    the     prima    facie
    requirements" of § 1782). Nor do the parties challenge the district
    court's conclusion that the first three statutory requirements
    -17-
    were met here, and that the fourth requirement was presumed to
    have been met.     The parties part ways, however, as to what, if
    any, burden applies to the second Intel factor, and who bears it.
    There are differing views as to the second Intel factor.
    Some courts have ruled that the party opposing discovery bears the
    burden of proving that the foreign tribunal would be unreceptive
    to the evidence and that, absent such proof, the factor weighs in
    favor of granting discovery. See In re Chevron Corp., 
    633 F.3d 153
    ,
    162-63 (3d Cir. 2011) (the party opposing discovery bears the
    burden of proof as to the second Intel factor and thus must
    "present adequate evidence to support [its] contention" that the
    "foreign jurisdiction" is not receptive to the discovery sought);
    Euromepa S.A. v. R. Esmerian, Inc., 
    51 F.3d 1095
    , 1100 (2d Cir.
    1995)   (holding   that   "a   district    court's   inquiry   into    the
    discoverability    of   requested    materials   should   consider    only
    authoritative proof that a foreign tribunal would reject evidence
    obtained with the aid of section 1782. . . .         Absent this type of
    clear directive, however, a district court's ruling should be
    informed by section 1782's overarching interest in 'providing
    equitable and efficacious procedures for the benefit of tribunals
    and litigants involved in litigation with international aspects'"
    (quoting Senate Report at 3783)).
    -18-
    Other courts have required "authoritative proof" of the
    receptivity of the foreign tribunal before finding that this factor
    weighs in favor of discovery.         See, e.g., In re Babcock Borsig AG,
    
    583 F. Supp. 2d 233
    , 241 (D. Mass. 2008) (denying discovery until
    there    was    an   affirmative    indication    of   the   relevant   foreign
    tribunal's       receptivity   to    the     requested   materials,     despite
    recognizing it had authority under the statute to allow the
    discovery "even in the face of uncertainty about the [foreign
    tribunal's] position").
    Still other courts have not specifically placed a burden
    of proof on either party as to any of the Intel factors and,
    instead, seem to have neutrally analyzed the contentions and
    supporting evidence presented by all the parties in deciding
    whether to exercise their discretion.             See, e.g., In re Clerici,
    
    481 F.3d 1324
    , 1335 (11th Cir. 2007) (considering the "particular
    factual circumstances" of the case as to the first Intel factor;
    looking at the entire record to conclude that there was nothing in
    it "to suggest that the district court should have declined to
    grant the § 1782 application" as to the second and third Intel
    factors; and noting that if the party opposing discovery "wished
    to pursue his 'unduly intrusive' argument" under the fourth Intel
    factor, that party should have moved the court to limit discovery);
    see     also    Consorcio   Ecuatoriano      de   Telecomunicaciones      S.A.,
    
    -19- 747 F.3d at 1271
    , 1273 (noting that the Supreme Court established
    in Intel the "factors to be considered" and refusing to find abuse
    of discretion where the party opposing the discovery failed to
    substantiate its "blanket claim" that the discovery sought was
    unduly burdensome under the fourth Intel factor); Heraeus Kulzer,
    GmbH v. Biomet, Inc., 
    633 F.3d 591
    , 598 (7th Cir. 2011) (holding
    that the district court's denial of discovery was unreasonable
    because,   among   other   things,   the   party   opposing   discovery
    "refus[ed] to present any evidence" in support of its contention
    that granting the discovery request would be burdensome); see also
    In re ASML U.S., Inc., 
    707 F. App'x 476
    , 477 (9th Cir. 2017)
    (second Intel factor met because movant submitted "unrebutted
    declarations [] that the foreign tribunals would welcome the
    discoverable evidence"); Chevron Corp. v. Shefftz, 
    754 F. Supp. 2d 254
    , 261–62 (D. Mass. 2010) (acknowledging there are different
    views on who bears the burden of proof on the second Intel factor
    and taking "a middle ground between the two views").
    In Intel, the Supreme Court set out a list of factors
    -- rather than elements of a claim -- "that bear consideration" by
    the district court when it exercises its discretion under the
    statute, leaving it up to the district court to assign those
    factors weight based on the particular circumstances of each case.
    Intel 
    Corp., 542 U.S. at 264
    .        Because the Supreme Court gave
    -20-
    great flexibility and discretion to district courts in weighing
    the different factors, we believe the Supreme Court did not intend
    to place a burden on either party.        Rather, it intended for both
    parties to make their arguments as to all of the factors, and for
    the district court to then determine whom those factors favor.           In
    this sense, we do not see the factors as creating a "burden" for
    either party to meet, but rather as considerations to guide the
    district court's decision.       Both parties are free to argue their
    positions and submit evidence in support thereof, and the district
    court is then to consider all of that in weighing these factors.
    Of course, a party who relies on a "blanket assertion" or does not
    properly   substantiate   its    contentions   runs   the   risk    of   not
    persuading the court to exercise its discretion in its favor.
    We understand the Second and Third Circuits' reasoning
    for placing the burden of proof on the party opposing discovery,
    especially in light of the interest in "providing equitable and
    efficacious procedures for the benefit of tribunals and litigants
    involved in litigation with international aspects."                Euromepa
    
    S.A., 51 F.3d at 1100
    (quoting Senate Report at 3783).                   We,
    however, do not believe that such a requirement is necessary to
    further these interests.        It is clear that, even if all of the
    statutory requirements are met, the district court may still deny
    the discovery request if it finds that the weighing of the Intel
    -21-
    factors favors denial, regardless of whether the respondent has
    proffered    reasoning   for   the   district     court   to   exercise   its
    discretion.     Likewise, the fact that courts may adjudicate ex
    parte petitions under § 1782, see Gushlak v. Gushlak, 
    486 F. App'x 215
    , 217 (2d Cir. 2012) (noting that "it is neither uncommon nor
    improper for district courts to grant applications made pursuant
    to § 1782 ex parte"), and should still consider the Intel factors
    regardless of the absence of the respondent, further suggests that
    respondent does not bear a burden of proof as to the discretionary
    factors.    Furthermore, requiring the party opposing discovery to
    present     "authoritative     proof"       of   the   foreign   tribunal's
    unreceptiveness, as Schlich proposes, could place pressure on the
    foreign tribunal and could exacerbate comity and parity concerns
    which "may be important as touchstones for a district court's
    exercise of discretion."       Intel 
    Corp., 542 U.S. at 261
    .        And, if
    the opposing party fails to provide such exigent proof, then that
    could give carte blanche to the moving party for seeking discovery
    that is only marginally relevant to the foreign proceeding, thus
    potentially promoting fishing expeditions.             We thus believe that
    the construction we have given to the Intel factors is consistent
    with the purpose of the statute, as well as with Congress's intent
    to give the district court broad discretion to determine whether
    discovery is warranted in a specific case.
    -22-
    Here, both parties argued and submitted authority in
    support of their respective positions as to the EPO's receptivity
    to   assistance   from   U.S.   courts.      Schlich    pointed   to   Akebia
    Therapeutics, Inc. v. FibroGen, Inc., 
    793 F.3d 1108
    , 1112-13
    (9th Cir. 2015), where, after the Ninth Circuit affirmed the
    district court's grant of discovery pursuant to § 1782, the
    evidence obtained pursuant to that order was submitted to the EPO
    in an opposition proceeding, and the EPO admitted and relied upon
    the evidence obtained with the U.S. court's assistance.                 Broad
    tried to rebut Schlich's contention by arguing that Akebia is
    distinguishable     inasmuch    as   the    discovery   sought    there   was
    relevant to the EPO proceedings in that case, as opposed to the
    discovery being sought here which, according to Broad, is not
    relevant to these opposition proceedings.         Broad also submitted a
    declaration from a former EPO official stating that the EPO lacked
    jurisdiction to determine inventorship issues and, thus, that the
    evidence sought by Schlich would be irrelevant.            Schlich did not
    rebut this evidence. The district court considered these arguments
    and evidence and determined that, because it appeared that the EPO
    would not make a determination as to inventorship in the opposition
    proceedings, the EPO would not be receptive to the evidence sought
    by Schlich.       The district court then concluded that, because
    Schlich had not demonstrated that the evidence he was seeking was
    -23-
    relevant, as the evidence in Akebia was, he had failed to convince
    the   court    that   the   EPO    would   be   receptive    to    the    court's
    assistance.      Contrary to Schlich's assertions, we do not read the
    court's decision as placing the burden of proof on Schlich on the
    receptiveness issue.         Instead, our reading indicates that the
    district court correctly considered all of the arguments and
    evidence submitted by both parties, found Broad's position and
    supporting      evidence    more   convincing,    and   thus      found   itself
    unconvinced that the second Intel factor favored granting the
    discovery.
    We note that the district court considered the relevance
    of the discovery sought as part of its consideration of the EPO's
    receptivity to assistance from U.S. courts under the second Intel
    factor.   Broad argues that relevance should instead be treated as
    a threshold statutory factor that the applicant must prove before
    the court exercises its discretion. We have not had the opportunity
    to address the role of relevance in the § 1782 analysis since Intel
    was decided, but the Second Circuit has stated that the statutory
    requirement prescribing that information be "for use" in a foreign
    proceeding incorporates a relevance requirement.                   See Certain
    Funds, Accounts and/or Inv. 
    Vehicles, 798 F.3d at 120
    n.7; Mees v.
    Buiter, 
    793 F.3d 291
    , 299 n.10 (2d Cir. 2015).              We agree with the
    Second Circuit that "it is difficult to conceive how information
    -24-
    that is plainly irrelevant to the foreign proceeding could be said
    to be 'for use' in that proceeding."          Certain Funds, Accounts
    and/or Inv. 
    Vehicles, 798 F.3d at 120
    n.7.         Therefore, a request
    for discovery under § 1782 that is plainly irrelevant to the
    foreign proceeding will fail to meet the statutory "for use"
    requirement, and must be denied before the court reaches the
    discretionary Intel factors.
    However, even when a discovery request is sufficiently
    relevant to be deemed "for use" in a foreign proceeding, there is
    nothing that prevents district courts from considering relevancy
    under   the    discretionary   Intel   factors,   including   the   second
    factor, which focuses on the "nature of the foreign tribunal, the
    character of the proceedings underway abroad, and the receptivity
    of the foreign government or the court or agency abroad to U.S.
    federal-court judicial assistance."       Intel 
    Corp., 542 U.S. at 264
    .
    For example, although evidence may be broadly relevant to the
    applicant's claims in a foreign tribunal, the nature of the foreign
    proceedings and the rules of the foreign tribunal may relegate the
    information to marginal relevance.        Where the information sought
    is only marginally relevant, the district court may decide to
    exercise its discretion to exclude the evidence because other
    concerns outweigh the need for the discovery.        See 
    Mees, 793 F.3d at 299
    n.10 (noting that "[a] request that appears only marginally
    -25-
    relevant     to    the     foreign    proceeding"         may     be     denied    as   a
    discretionary matter because it "may in certain cases suggest that
    the   application        'is   made   in    bad    faith,   for        the   purpose    of
    harassment,       or   unreasonably        seeks       cumulative       or   irrelevant
    materials'" (quoting Euromepa 
    S.A., 51 F.3d at 1101
    n.6)); In Re
    Green Dev. Corp. S.A. De C.V., No. CCB-15-2985, 
    2016 WL 640791
    (D. Md. 2016) (finding the "for use" requirement satisfied where
    petitioner requested discovery in relation to an adverse party's
    alleged ex parte communications with the Honduran Supreme Court in
    order to submit that discovery to the Honduran Supreme Court and
    mitigate the effect of the improper communications, but ultimately
    denying the requested discovery under the Intel discretionary
    factors because the request was based on "sheer speculation," among
    other reasons).
    Here, although the information sought by Schlich may
    have been relevant to the EPO opposition proceeding in a general
    sense, the district court concluded that limitations on the EPO's
    jurisdiction to consider inventorship rendered it irrelevant.
    Accordingly, although the district court treated as "undisputed"
    Schlich's satisfaction of the "for use" statutory requirement, it
    was   well   within      its   discretion         to   conclude    that      the   second
    discretionary factor weighed against ordering discovery because
    the information sought was irrelevant due to the nature of the
    -26-
    proceedings before the EPO, and to deny the discovery request based
    on that conclusion.
    III.     Conclusion
    For the reasons stated above, we conclude that the
    district court did not misapply the law in denying the requested
    discovery under § 1782.     Based on its finding that the requested
    discovery would be irrelevant under the second Intel factor and,
    thus, that the EPO would be unreceptive to that information, the
    district court did not abuse its discretion.9         Furthermore, the
    district   court   also   ordered   supplemental   briefing   to   better
    apprehend the issues before it and showed foresight and restraint
    in denying without prejudice pending further developments. We thus
    affirm the district court's order denying discovery under § 1782.
    Affirmed.
    9  We decline Broad's invitation to consider the EPO's preliminary
    and non-binding opinion of April 13, 2017 -- which stated that the
    discovery proceedings underlying this appeal "are based on issues
    of entitlement in so far as they attempt to put into question the
    inventorship as allocated by the distribution of the contribution
    by Mr. Kowalski," and that "the EPO has no power to resolve . . .
    matters of entitlement" -- because it was issued after the district
    court had rendered its decision and, thus, was not considered or
    relied on by the district court.
