    SUMMARY**
    Copyright Law
    The panel affirmed the district court’s grant of summary
    judgment in favor of CoreLogic, Inc., on professional real
    estate photographers’ claims that CoreLogic removed
    copyright management information from their photographs
    and distributed their photographs with the copyright
    management information removed, in violation of 17 U.S.C.
    § 1202(b)(1)-(3), a part of the Digital Millennium Copyright
    Act.
    The photographers alleged that CoreLogic’s Multiple
    Listing Services software removed copyright management
    information metadata from their photographs. The panel held
    that § 1202(b) requires a showing that the defendant knew the
    prohibited act would “induce, enable, facilitate, or conceal”
    infringement. The panel concluded that the photographers
    did not offer evidence to satisfy this mental state requirement
    because they did not provide evidence from which one could
    infer that future infringement was likely, albeit not certain, to
    occur as a result of the removal or alteration of copyright
    management information.
    The panel affirmed the district court’s rulings regarding
    discovery and costs.

    OPINION
    BERZON, Circuit Judge:
    Residential real estate sales today depend largely on
    online sites displaying properties for sale. Plaintiffs Robert
    Stevens and Steven Vandel (“the Photographers”) are
    professional real estate photographers who take photographs
    of listed properties and license them to real estate agents.
    The real estate agents, in turn, upload such photographs to
    Multiple Listing Services (“MLS”) — computerized
    databases of listed properties — using Defendant
    CoreLogic’s software.
    In this action against CoreLogic, the Photographers allege
    that CoreLogic removed copyright management information
    from their photographs and distributed their photographs with
    the copyright management information removed, in violation
    of 17 U.S.C. § 1202(b)(1)–(3). We affirm the grant of
    summary judgment in favor of CoreLogic.

    FACTS AND PROCEEDINGS BELOW
    A. Metadata
    Stevens and Vandel are hired by real estate agents to take
    digital photographs of houses for sale. The Photographers
    retain the copyright in those photographs and license them to
    the agents. Like most digital photographs, at least some of
    Stevens’ and Vandel’s photographs contain metadata — i.e.,
    data about the image file itself. Metadata is not visible on the
    face of the image. Rather, it is either embedded in the digital
    file or stored outside the image file, such as in a “sidecar”
    file, and can be viewed using computer programs.
    Some metadata is generated automatically by cameras.
    The Exchangeable Image File Format (“EXIF”) is used by
    virtually all digital cameras to store information about the
    settings used to capture a digital image. EXIF information
    can include the make, model, and serial number of the camera
    taking the photograph; the shutter speed; the aperture
    settings; light sensitivity; the focal length of the lens; and
    even, in some cases, the location at which the photo was
    captured. Essentially, EXIF metadata provides information
    about when the image was taken and under what technical
    conditions.
    Other metadata may be added manually, either by
    programming the camera or by adding information after
    taking the picture, using photo editing software. Such
    metadata is often stored in IPTC format, named for the
    International Press Telecommunications Council, which
    developed metadata standards to facilitate the exchange of
    news. IPTC metadata can include, for example, the title of
    the image, a caption or description, keywords, information
    STEVENS V. CORELOGIC                       5
    about the photographer, and copyright restrictions. It may be
    used to check copyright information, to sort images, and to
    provide accurate search results in an image database or search
    engine. A small number of fields such as Author/Creator,
    Copyright, and Caption/Description exist in both EXIF and
    IPTC formats.
    Copyright law restricts the removal or alteration of
    copyright management information (“CMI”) — information
    such as the title, the author, the copyright owner, the terms
    and conditions for use of the work, and other identifying
    information set forth in a copyright notice or conveyed in
    connection with the work. See 17 U.S.C. § 1202(b)–(c). Both
    EXIF and IPTC metadata can contain “copyright
    management information.”
    B. CoreLogic Software
    CoreLogic is a California-based corporation that develops
    and provides software to Multiple Listing Services. Known
    as one of the “Big 3” real estate software vendors nationally,
    CoreLogic currently markets, or has previously marketed,
    several MLS software platforms, including Matrix, InnoVia,
    Fusion, MLXchange, Tempo 4, and Tempo 5. The
    Photographers allege that CoreLogic’s software removed
    CMI metadata from their photographs, in violation of
    17 U.S.C. § 1202(b).
    Because image files can be very large, CoreLogic’s MLS
    software resizes or “downsamples” images. Downsampling
    entails creating and saving a copy of an uploaded image in a
    smaller number of pixels and deleting the original image; the
    process reduces storage size, facilitates computer display, and
    helps images load faster on web pages.
    6                     STEVENS V. CORELOGIC
    The image processing aspect of CoreLogic’s software was
    not developed by CoreLogic entirely on its own. Like
    virtually all software, CoreLogic’s software incorporated
    “libraries” — pre-written code that can be used by a computer
    program and that enables software to develop in a modular
    fashion. These libraries are unable to read EXIF data from
    image files or to write EXIF data to image files. Thus, when
    images are copied or resized using the code from these pre-
    existing libraries, metadata attached to those images is not
    retained.1
    The Photographers2 filed this action in May 2014.
    Significantly, the dispute is limited to metadata. The
    Photographers do not allege that CoreLogic’s software
    removed visible CMI, such as digital watermarks, from their
    1
    It is not uncommon for image processing software to fail to preserve
    metadata. Tests conducted by the Embedded Metadata Group in 2015
    revealed that, of fifteen social media websites studied, eight preserved
    EXIF metadata and seven, including, Facebook, Instagram, and Twitter,
    did not.       Some image-processing libraries, however, such as
    “ImageMagick,” do read and write EXIF data, and thus transfer EXIF
    metadata to the new image file when resizing.
    2
    Stevens’ company, Affordable Aerial Photography, was named as
    an additional plaintiff in the amended complaint. Affordable Aerial
    Photograph did not, however, file a timely notice of appeal from the
    district court’s July 5, 2016 judgment: The Notice of Appeal filed on July
    29, 2016 identified only Stevens and Vandel as appellants. An amended
    notice of appeal was filed several months later, on January 26, 2017, and
    included Affordable Aerial Photography. That notice of appeal was
    untimely as to the July 5, 2016 judgment. See Fed. R. App. P. 4(a)(1).
    We therefore lack jurisdiction to consider the appeal by Affordable Aerial
    Photography as it relates to the July 5, 2016 judgment. The amended
    notice of appeal was, however, timely as to the January 11, 2017 order
    denying the Photographers’ motion to re-tax costs, and Affordable Aerial
    Photography is therefore properly a party as to that portion of the appeal.
    STEVENS V. CORELOGIC                       7
    photographs, and indeed, CoreLogic’s software does not
    detect, recognize, or remove visible CMI. Cf. Murphy v.
    Millennium Radio Grp. LLC, 
    650 F.3d 295
    , 305 (3d Cir.
    2011) (imposing liability on a defendant who cropped out the
    photographer’s name from the “gutter” copyright credit
    before posting a photograph online).
    After receiving the Photographers’ initial complaint,
    CoreLogic modified its software to ensure that EXIF
    metadata is copied and restored to images processed by
    CoreLogic’s MLS software. These modifications were made
    within a few months of receiving the initial complaint,
    although testing and installation of the revised version on all
    MLSs using CoreLogic software took several more months.
    The Photographers contend that, even after these changes,
    CoreLogic software continues to remove IPTC metadata.
    In addition to providing MLS software — which, again,
    real estate agents use to share information about properties
    with other agents — CoreLogic also operates the Partner
    InfoNet program, which allows MLSs to license their
    aggregated real estate listing data to mortgage lenders and
    servicers, in exchange for a share of the licensees’ revenue.
    CoreLogic used photographs taken and owned by the
    Photographers on Partner InfoNet products.
    After the discovery deadline, but before all discovery
    disputes were resolved, Core Logic filed a motion for
    summary judgment. The district court granted summary
    judgment in favor of CoreLogic and denied as moot the
    Photographers’ motion to compel the production of additional
    documents.
    8                 STEVENS V. CORELOGIC
    After entry of judgment, CoreLogic filed a Bill of Costs,
    to which the Photographers objected. The district court
    denied the Photographers’ motion to re-tax costs with respect
    to witness fees for CoreLogic corporate employees. This
    timely appeal followed.
    DISCUSSION
    A. Violation of 17 U.S.C. § 1202(b)
    The Photographers allege that CoreLogic’s software
    removed CMI metadata, in violation of 17 U.S.C.
    § 1202(b)(1), and that CoreLogic distributed images knowing
    that copyright management information was removed, in
    violation of 17 U.S.C. § 1202(b)(3). Reviewing de novo the
    district court’s decision to grant summary judgment to
    CoreLogic, see Perfect 10, Inc. v. Giganews, Inc., 
    847 F.3d 657
    , 665 (9th Cir. 2017), we affirm the grant of summary
    judgment.
    1. Section 1202(b) Requires an Affirmative
    Showing That the Defendant Knew the
    Prohibited Act Would “Induce, Enable,
    Facilitate, or Conceal” Infringement
    Section 1202(b)(1) provides: “No person shall, without
    the authority of the copyright owner or the law . . .
    intentionally remove or alter any copyright management
    information . . . knowing, or . . . having reasonable grounds
    to know, that it will induce, enable, facilitate, or conceal an
    infringement of any” copyright. 17 U.S.C. § 1202(b)(1).
    Section 1202(b)(3) provides: “No person shall, without the
    authority of the copyright owner or the law . . . distribute,
    import for distribution, or publicly perform works, copies of
    STEVENS V. CORELOGIC                                9
    works, or phonorecords, knowing that copyright management
    information has been removed or altered without authority of
    the copyright owner or the law, knowing, or . . . having
    reasonable grounds to know, that it will induce, enable,
    facilitate, or conceal an infringement of any” copyright. 
    Id. § 1202(b)(3).3
    Both provisions thus require the defendant to
    possess the mental state of knowing, or having a reasonable
    basis to know, that his actions “will induce, enable, facilitate,
    or conceal” infringement.
    The Photographers have not offered any evidence to
    satisfy that mental state requirement.4 Their primary
    argument is that, because one method of identifying an
    3
    The Photographers’ complaint also alleges a violation of 17 U.S.C.
    § 1202(b)(2). Section 1202(b)(2) refers to the “distribut[ion] or import for
    distribution [of] copyright management information knowing that the
    copyright management information has been removed or altered without
    authority of the copyright owner or the law.” 17 U.S.C. § 1202(b)(2)
    (emphasis added). The Photographers do not specifically allege any
    instances involving the distribution of altered CMI separate from the
    distribution of the copyrighted photographs. As the elements of the two
    statutory provisions are otherwise indistinguishable, the Photographers
    have not plausibly stated a claim under Section 1202(b)(2) different from
    their claim under Section 1202(b)(3). We therefore discuss in the text
    only the Section 1202(b)(3) claim.
    4
    As this reason is a sufficient basis for concluding that the
    Photographers’ claims fail, we do not consider whether CoreLogic
    “intentionally” removed CMI, whether the Photographers presented
    sufficient evidence that the photographs contained CMI at the time they
    were uploaded, whether the Photographers impliedly licensed the removal
    of CMI, or whether CoreLogic, as a software developer, can be liable for
    third parties’ use of its software.
    10                   STEVENS V. CORELOGIC
    infringing photograph has been impaired,5 someone might be
    able to use their photographs undetected. That assertion rests
    on no affirmative evidence at all; it simply identifies a
    general possibility that exists whenever CMI is removed.
    As we interpret Section 1202(b), this generic approach
    won’t wash. It is a fundamental principle of statutory
    interpretation that we must “give effect, if possible, to every
    clause and word of a statute,” Montclair v. Ramsdell,
    
    107 U.S. 147
    , 152 (1883), “so that no part will be inoperative
    or superfluous, void or insignificant,” Corley v. United States,
    
    556 U.S. 303
    , 314 (2009); see also Hibbs v. Winn, 
    542 U.S. 88
    , 101 (2004); Astoria Fed. Savs. & Loan Ass’n v. Solimino,
    
    501 U.S. 104
    , 112 (1991). To avoid superfluity, the mental
    state requirement in Section 1202(b) must have a more
    specific application than the universal possibility of
    encouraging infringement; specific allegations as to how
    identifiable infringements “will” be affected are necessary.
    At the same time, as the statute is written in the future
    tense, the Photographers need not show that any specific
    infringement has already occurred. Also, recognizing that
    “nothing is completely stable, no plan is beyond alteration,”
    5
    As noted, CoreLogic’s software does preserve visible watermarks,
    which Stevens and Vandel testified they sometimes use to identify their
    photographs. Experts advise that watermarks offer a more reliable way of
    indicating copyright protection than metadata. See Bert P. Krages, Legal
    Handbook for Photographers: The Rights and Liabilities of Making and
    Selling Images 85 (4th ed. 2017) (recommending that photographers “put
    the copyright management information on the face of the image, such as
    in a watermark, rather than rely solely on information contained in
    metadata” because the use of image editing software to clone over a
    watermark is more likely to be seen as intentional than the removal of
    metadata).
    STEVENS V. CORELOGIC                      11
    we have previously observed that statutes requiring
    knowledge that a future action “will” occur do not “require
    knowledge in the sense of certainty as to a future act.”
    United States v. Todd, 
    627 F.3d 329
    , 334 (9th Cir. 2010).
    Rather, knowledge in the context of such statutes signifies “a
    state of mind in which the knower is familiar with a pattern
    of conduct” or “aware of an established modus operandi that
    will in the future cause a person to engage in” a certain act.
    
    Id. Applying that
    concept here, we hold that a plaintiff
    bringing a Section 1202(b) claim must make an affirmative
    showing, such as by demonstrating a past “pattern of
    conduct” or “modus operandi”, that the defendant was aware
    of the probable future impact of its actions.
    Our conclusion about the import of the “induce[d],
    enable[d], facilitate[d], or conceal[ed]” prong is supported by
    the legislative history of Section 1202. That provision was
    enacted to implement obligations of parties to the WIPO
    Copyright Treaty (“WCT”) and the WIPO Performances and
    Phonograms Treaty. See S. Rep. No. 105-190, at 5, 9 (1998).
    The initial draft of the WCT provision regarding CMI
    provided:
    Contracting parties shall make it unlawful for
    any person knowingly . . . (i) to remove or
    alter any electronic rights management
    information without authority; [or] (ii) to
    distribute, import for distribution or
    communicate to the public, without authority,
    copies of works from which electronic rights
    management information has been removed or
    altered without authority.
    12                STEVENS V. CORELOGIC
    World Intellectual Property Organization [WIPO], Basic
    Proposal for the Substantive Provisions of the Treaty on
    Certain Questions Concerning the Protection of Literary and
    Artistic Works to Be Considered by the Diplomatic
    Conference, art. 14(1), WIPO Doc. CRNR/DC/4 (Aug. 30,
    1996).
    In response to requests from delegates that the provision
    be modified to require a connection to an infringing purpose,
    the provision was redrafted as follows:
    Contracting Parties shall provide adequate and
    effective legal remedies against any person
    knowingly performing any of the following
    acts knowing or, with respect to civil remedies
    having reasonable grounds to know, that it
    will induce, enable, facilitate or conceal an
    infringement of any right covered by this
    Treaty or the Berne Convention: (i) to remove
    or alter any electronic rights management
    information without authority; (ii) to
    distribute, import for distribution, broadcast or
    communicate to the public, without authority,
    works or copies of works knowing that
    electronic rights management information has
    been removed or altered without authority.
    WIPO Copyright Treaty art. 12, Dec. 20 1996 (emphasis
    added). The revision thus makes clear that the “induce,
    enable, facilitate or conceal” requirement is intended to limit
    liability in some fashion — specifically, to instances in which
    the defendant knows or has a reasonable basis to know that
    the removal or alteration of CMI or the distribution of works
    with CMI removed will aid infringement.
    STEVENS V. CORELOGIC                      13
    When Congress was considering the WIPO Copyright
    Treaties Implementation Act — a part of the Digital
    Millennium Copyright Act (“DMCA”) that included the new
    Section 1202 — the Register of Copyrights emphasized that
    Section 1202’s provisions “do not apply to those who act
    innocently. . . . Liability for the removal or alteration of
    information requires the actor to know or have reason to
    know that his acts ‘will induce, enable, facilitate or conceal’
    infringement.” WIPO Copyright Treaties Implementation
    Act, and Online Copyright Liability Limitation Act: Hearing
    Before the H. Subcomm. on Courts and Intellectual Property
    of the H. Comm. on the Judiciary, 105th Cong. 51 (1997)
    (statement of Marybeth Peters, Register of Copyrights,
    Copyright Office of the United States).
    In short, to satisfy the knowledge requirement, a plaintiff
    bringing a Section 1202(b)(1) claim must offer more than a
    bare assertion that “when CMI metadata is removed,
    copyright infringement plaintiffs . . . lose an important
    method of identifying a photo as infringing.” Instead, the
    plaintiff must provide evidence from which one can infer that
    future infringement is likely, albeit not certain, to occur as a
    result of the removal or alteration of CMI.
    2. The Photographers Have Failed to Make the
    Required Affirmative Showing
    The Photographers have not offered any specific evidence
    that removal of CMI metadata from their real estate
    photographs will impair their policing of infringement. There
    are no allegations, for example, of a “pattern of conduct” or
    “modus operandi” involving policing infringement by
    tracking metadata. 
    Todd, 627 F.3d at 334
    . Indeed, the
    evidence presented cuts against any inference that CMI
    14                 STEVENS V. CORELOGIC
    metadata is of any practical significance to the Photographers
    in policing copyright infringement of their images.
    The Photographers have not, for example, averred that
    they have ever used CMI metadata to prevent or detect
    copyright infringement, much less how they would do so.
    Vandel testified that, before this lawsuit began, he had never
    “looked at any metadata information on any photograph in an
    MLS system.” On the only two occasions Vandel became
    aware of unauthorized use of his photographs, he learned
    about the unauthorized use from the real estate agent who
    commissioned the photographs. The agent saw the image
    elsewhere and contacted Vandel to ask if he had permitted the
    use. Stevens similarly testified that he had “[n]ever tried to
    download a photo off an MLS listing . . . and look at its
    properties, its metadata,” that he “d[id]n’t think you can pull
    up metadata off of an MLS listing,” and that he “didn’t even
    realize you could click on a picture off the Internet, right-
    click it, and get metadata off of it.” The testimony of both
    Stevens and Vandel undermines any ostensible relationship
    between the removal of CMI metadata and their policing of
    infringement.
    Nor have the Photographers brought forward any
    evidence indicating that CoreLogic’s distribution of real
    estate photographs ever “induce[d], enable[d], facilitate[d], or
    conceal[ed]” any particular act of infringement by anyone, let
    alone a pattern of such infringement likely to recur in the
    future. They identify no instance in which the removal of
    CMI metadata from any photograph “induce[d], enable[d],
    STEVENS V. CORELOGIC                            15
    facilitate[d] or conceal[ed] an infringement.”6 Moreover, a
    party intent on using a copyrighted photograph undetected
    can itself remove any CMI metadata, precluding detection
    through a search for the metadata. So on the record here, one
    cannot plausibly say that removal by a third party “will”
    make it easier to use a copyrighted photograph undetected,
    using “will” in the predictive sense we have indicated.
    Because the Photographers have not put forward any
    evidence that CoreLogic knew its software carried even a
    substantial risk of inducing, enabling, facilitating, or
    concealing infringement, let alone a pattern or probability of
    such a connection to infringement, CoreLogic is not liable for
    violating 17 U.S.C. § 1202(b).
    B. Discovery Rulings
    The Photographers also appeal the district court’s denial
    as moot of their motion to compel the production of
    documents, as well as the court’s related failure to address
    their Rule 56(d) request. See Fed. R. Civ. P. 56(d).7 We treat
    6
    In the time it has operated its MLS software, CoreLogic has only
    once received a DMCA takedown notice from a real estate photographer.
    17 U.S.C. § 512(c). CoreLogic promptly responded by removing the
    allegedly unauthorized and infringing copies. There is no evidence that
    that photographer used metadata to identify the allegedly infringing
    copies, that her photograph even contained metadata, or that the
    infringement identified had anything to do with removal or alteration of
    metadata.

    Federal Rule of Civil Procedure 56(d) provides: “If a nonmovant
    shows by affidavit or declaration that, for specified reasons, it cannot
    present facts essential to justify its opposition [to a motion for summary
    judgment], the court may: (1) defer considering the motion or deny it;

    Before discovery closed in September 2015, the
    Photographers filed motions to compel the production of
    certain documents and certain supplemental responses to
    interrogatories. The district court granted in part and denied
    in part those motions, ordering CoreLogic to identify in a
    privilege log any responsive documents it claimed were
    privileged. CoreLogic complied, serving an initial privilege
    log consisting of 1,049 entries, and later a revised privilege
    log.
    CoreLogic filed a motion for summary judgment before
    the district court ruled on the privilege claims. In addition to
    a memorandum of points and authorities opposing
    CoreLogic’s motion for summary judgment on the merits,
    counsel for the Photographers filed a Rule 56(d) declaration
    opposing summary judgment on the ground that the
    Photographers planned to move to compel the production of
    documents relevant to their claims that they believed not
    privileged. The declaration asserted that the documents were
    “likely to be directly relevant to each of the elements in
    17 U.S.C. § 1202, especially the mental state requirement of
    ‘knowing,’” and requested that the court defer consideration
    (2) allow time to obtain affidavits or declarations or to take discovery; or
    (3) issue any other appropriate order.”

    Kennedy characterizes as an implicit denial a failure expressly to
    address a Rule 56(f) motion. Federal Rule of Civil Procedure 56(d) was,
    until December 1, 2010, codified as Federal Rule of Civil Procedure 56(f).
    STEVENS V. CORELOGIC                       17
    of the summary judgment motion or extend the time for
    discovery.
    The photographers subsequently moved to compel the
    production of 603 e-mails and instant messages identified in
    the revised privilege log. The district court, however, granted
    summary judgment to CoreLogic before ruling on the motion
    to compel, and then, in the summary judgment order, denied
    the discovery motion as moot.
    District court discovery rulings denying a motion to
    compel discovery are ordinarily reviewed for abuse of
    discretion. See Hallett v. Morgan, 
    296 F.3d 732
    , 751 (9th
    Cir. 2002); see also Morton v. Hall, 
    599 F.3d 942
    , 945 (9th
    Cir. 2010); Qualls ex rel. Qualls v. Blue Cross of Cal., Inc.,
    
    22 F.3d 839
    , 844 (9th Cir. 1994). When the district court
    denies a motion to compel additional discovery as moot
    without considering its merits, however, the district court
    does not exercise any substantive discretion about the scope
    of discovery, so we review the denial of discovery de novo.
    Clark v. Capital Credit & Collection Servs., Inc., 
    460 F.3d 1162
    , 1178 (9th Cir. 2006); Garrett v. City & Cty. of San
    Francisco, 
    818 F.2d 1515
    , 1518 n.3, 1519 (9th Cir. 1987).
    Similarly, if a district court implicitly denies a Rule 56(d)
    motion by granting summary judgment without expressly
    addressing the motion, that omission constitutes a failure “to
    exercise its discretion with respect to the discovery motion,”
    and the denial is reviewed de novo. 
    Garrett, 818 F.2d at 1518
    n.3, 1519; see also Margolis v. Ryan, 
    140 F.3d 850
    , 853
    (9th Cir. 1998); 
    Kennedy, 90 F.3d at 1482
    ; 
    Qualls, 22 F.3d at 844
    . We have previously allowed that explanations for
    denials of Rule 56(d) request “need not be explicitly stated”
    when “the information sought . . . would not have shed light
    18                    STEVENS V. CORELOGIC
    on any of the issues upon which the summary judgment
    decision was based.” 
    Qualls, 22 F.3d at 844
    . But when the
    plaintiff requests additional discovery pursuant to Rule 56(d)
    and the materials that a “motion to compel sought to elicit”
    are relevant to the basis for the summary judgment ruling,
    district courts should provide reasons for denying the
    discovery motion and the Rule 56(d) request. See 
    Garrett, 818 F.2d at 1519
    . In this case, the communications that the
    Photographers sought could have “shed light” on whether, for
    example, CoreLogic intentionally removed CMI or knew
    CMI was removed without authorization — issues relevant to
    the district court’s summary judgment ruling, although not to
    our basis for affirming that ruling — and should have been
    addressed.
    Nonetheless, reviewing de novo the denials of the motion
    to compel and of the Rule 56(d) request, we affirm. As to the
    motion to compel, there is no indication that any of the
    documents sought are “relevant,” as required under Rule
    26(b)(1),9 to what we have held to be the dispositive issue —
    whether CoreLogic knew its actions would “induce, enable,
    facilitate, or conceal infringement.”10 The district court
    9
    Rule 26(b)(1) provides: “Unless otherwise limited by court order,
    . . . [p]arties may obtain discovery regarding any nonprivileged matter that
    is relevant to any party’s claim or defense and proportional to the needs
    of the case, considering the importance of the issues at stake in the action,
    the amount in controversy, the parties’ relative access to relevant
    information, the parties’ resources, the importance of the discovery in
    resolving the issues, and whether the burden or expense of the proposed
    discovery outweighs its likely benefit.” Fed. R. Civ. P. 26(b)(1).
    10
    According to the Photographers’ motion to compel, the documents
    at issue fell into three categories: (1) “Product Development and
    Modification” documents regarding CoreLogic’s development and
    modification of the CoreLogic software at issue; (2) “Sales Pitches and
    STEVENS V. CORELOGIC                            19
    directed that the motion to compel include “[a] statement as
    to why the discovery is needed.” The sole explanation
    offered for why the documents were needed was that they
    would show CoreLogic knew its software removed EXIF
    metadata before the litigation began, and knew its software
    continues to remove IPTC metadata, even after the software
    was modified to preserve EXIF metadata after this lawsuit
    was filed. As the Photographers have not made any showing
    that the documents listed in the privilege log are relevant to
    the dispositive question — whether CoreLogic’s software
    will “induce, enable, facilitate, or conceal” any act of
    infringement — we affirm the denial of the motion to compel.
    The denial of the Rule 56(d) request was proper for
    similar reasons. Rule 56(d) provides “a device for litigants to
    avoid summary judgment when they have not had sufficient
    time to develop affirmative evidence.” United States v.
    Kitsap Physicians Serv., 
    314 F.3d 995
    , 1000 (9th Cir. 2002).
    A party seeking additional discovery under Rule 56(d) must
    “explain what further discovery would reveal that is ‘essential
    to justify [its] opposition’ to the motion[] for summary
    judgment.” Program Eng’g, Inc. v. Triangle Publ’ns, Inc.,
    
    634 F.2d 1188
    , 1194 (9th Cir. 1980) (first alteration in
    original).
    This showing cannot, of course, predict with accuracy
    precisely what further discovery will reveal; the whole point
    of discovery is to learn what a party does not know or,
    without further information, cannot prove. See, e.g., Pac.
    Internal Discussions” emails and instant messages regarding this lawsuit;
    and (3) “Business Matters” emails and instant messages between non-
    attorneys regarding “images incorporated into a product” and “contract
    language.”
    20                   STEVENS V. CORELOGIC
    Fisheries Inc. v. United States, 
    484 F.3d 1103
    , 1111 (9th Cir.
    2007) (“[T]he purpose of discovery is to aid a party in the
    preparation of its case . . . .”); Fed. R. Civ. P. 26(b) advisory
    committee’s note to 1946 amendment) (“The purpose of
    discovery is to allow a broad search for facts . . . or any other
    matters which may aid a party in the preparation or
    presentation of his case.”). But for purposes of a Rule 56(d)
    request, the evidence sought must be more than “the object of
    pure speculation.” California v. Campbell, 
    138 F.3d 772
    ,
    779–80 (9th Cir. 1998) (citation omitted). A party seeking to
    delay summary judgment for further discovery must state
    “what other specific evidence it hopes to discover [and] the
    relevance of that evidence to its claims.” Program 
    Eng’g, 634 F.2d at 1194
    (emphasis added). In particular, “[t]he
    requesting party must show [that]: (1) it has set forth in
    affidavit form the specific facts it hopes to elicit from further
    discovery; (2) the facts sought exist; and (3) the sought-after
    facts are essential to oppose summary judgment.” Family
    Home & Fin. Ctr., Inc. v. Fed. Home Loan Mortg. Corp.,
    
    525 F.3d 822
    , 827 (9th Cir. 2008) (emphasis added).11
    The Photographers did not comply with those
    requirements here. Extensive discovery had taken place
    before the district court ruled on CoreLogic’s motion for
    summary judgment.         The Photographers had taken
    depositions of 16 CoreLogic employees, served and received
    responses to 42 interrogatories, and served 114 requests for
    production of documents. The additional information sought
    was a general request for all allegedly privileged documents
    11
    Garrett, on which the Photographers rely, is not to the contrary.
    Garrett emphasized that the plaintiff there “made clear the information
    sought, did not seek broad additional discovery, . . . and indicated the
    purpose for which this information was 
    sought.” 818 F.2d at 1518
    –19.
    STEVENS V. CORELOGIC                      21
    where no attorney was listed as an author or recipient,
    coupled with a bare assertion that the “documents are likely
    to be directly relevant to each of the elements in 17 U.S.C.
    § 1202, especially the mental state requirement of
    ‘knowing.’”
    A request at that level of generality is insufficient for
    Rule 56(d) purposes. The Photographers did not in their Rule
    56(d) declaration enumerate any “specific facts” they hoped
    to elicit from further discovery, Family Home & Fin. 
    Ctr., 525 F.3d at 827
    , or “provide any basis or factual support for
    [their] assertions that further discovery would lead” to those
    facts, 
    Margolis, 140 F.3d at 854
    . And, as we have explained,
    the only specific explanation in the record — which appeared
    in the motion to compel, not in the Rule 56(d) declaration —
    indicates that the information sought would not illuminate the
    determinative inquiry, whether CoreLogic’s software will
    “induce, enable, facilitate, or conceal an infringement.”
    We therefore affirm the denial of the Photographers’
    request to the district court to delay a decision on summary
    judgment and permit additional discovery.
    C. Motion to Retax Costs
    Finally, the district court did not err in awarding fees for
    corporate witnesses as costs and denying the Photographers’
    motion to retax costs.
    Rule 54 permits prevailing parties to recover costs other
    than attorney’s fees, unless otherwise provided. Fed. R. Civ.
    P. 54(d)(1). The Photographers urge that corporate directors
    22                      STEVENS V. CORELOGIC
    or officers may not recover the witness fees set by 28 U.S.C.
    § 1821 when appearing in support of the corporate party.12
    As a general rule, parties may not recover witness fees for
    their own attendance. See, e.g., Barber v. Ruth, 
    7 F.3d 636
    ,
    646 (7th Cir. 1993), superseded on other grounds by
    amendment to Federal Rules of Civil Procedure, as
    recognized in Little v. Mitsubishi Motors N. Am., Inc., 
    514 F.3d 699
    , 701–02 (7th Cir. 2008). The expenses of corporate
    directors or officers may, however, be taxable, even when
    those individuals are testifying on behalf of a corporate party
    to the suit, provided “[n]o recovery . . . [is] sought from [the
    officers] individually.” See Kemart Corp. v. Printing Arts
    Research Labs., Inc., 
    232 F.2d 897
    , 901 (9th Cir. 1956)
    (citation omitted); 10 Charles A. Wright & Arthur R. Miller,
    Federal Practice and Procedure § 2678 (3d ed. 1998) (“The
    expenses of witnesses who are themselves parties normally
    are not taxable. For example, real parties in interest or parties
    suing in a representative capacity are not entitled to fees or
    allowances as witnesses. The expenses of a director or
    officer of a corporation who is not personally involved in the
    litigation may be taxable, however, even if that individual is
    testifying on behalf of the organization and the latter is a
    party to the suit.”). “The allowance or disallowance of items
    of costs is determined by statute, rule, order, usage, and
    practice of the instant court.” 
    Kemart, 232 F.2d at 899
    .
    Southern District of California Local Rule 54.1(b)(4)(c)
    specifically provides that “[w]itness fees for officers and
    employees of a corporation” may be recoverable as costs “if
    they are not parties in their individual capacities.” S.D. Cal.
    Civ. R. 54.1(b)(4)(c). During the course of this litigation, the
    12
    Section 1821 governs the attendance fees for witnesses.
    STEVENS V. CORELOGIC                             23
    Photographers took one Rule 30(b)(6) deposition of
    CoreLogic as a corporate entity, at which nine employees
    designated by CoreLogic testified,13 and seven depositions of
    CoreLogic officers or managing agents. Thus, sixteen
    CoreLogic employees testified and were paid $40 per day, in
    accordance with 28 U.S.C. § 1821, for a total of $640 in
    witness fees. The district court did not abuse its discretion in
    relying upon Local Rule 54.1 to allow and tax as costs the
    witness fees for CoreLogic’s corporate officers.
    AFFIRMED.
    13
    A Rule 30(b)(6) deposition is “treated as a single deposition even
    though more than one person may be designated to testify.” Fed. R. Civ.
    P. 30(a) advisory committee’s note to 1993 amendment.
