    *            *         *
    Petitioners seek the disqualification of the law firm of AlvaradoSmith,
    which: (1) previously represented another law firm in an attorney fee dispute; and (2) in
    this case, represents an expert seeking consulting fees arising out of the same underlying
    litigation as the attorney fee dispute. We issued a stay order and order to show cause.
    We now conclude AlvaradoSmith’s wide-ranging access to privileged information in the
    first representation and the substantial relationship between the two matters requires the
    disqualification of AlvaradoSmith. We therefore grant writ relief countermanding the
    respondent court’s contrary order.
    FACTS
    Matter No. 1: Petitioner Shared Memory Graphics LLC (SM Graphics)
    hired the law firm of Floyd & Buss in May 2009 to pursue patent infringement litigation
    against a list of leading electronics firms. Matter No. 1 commenced in July 2009 in
    Arkansas, but was subsequently transferred to the United States District Court for the
    Northern District of California. The SM Graphics retention agreement covered
    “litigation activities with respect to” 14 patents. The record is unclear, however, as to
    whether all 14 of these patents were actually at issue in Matter No. 1, or if only two of the
    1
    14 patents were the focus of Matter No. 1. In March 2011, SM Graphics and related
    1
    The petition defines the SM Graphics patents as United States Patent Nos.
    5,712,664 and 6,081,279, and indicates these two patents were asserted in Matter No. 1.
    The petition does not actually state, however, that the other 12 patents in the SM
    2
    entities obtained a cash settlement (totaling approximately $45 million) from Samsung
    (one of the defendants in Matter No. 1) as part of a combined licensing and settlement
    agreement encompassing not only the patents at issue in Matter No. 1, but also numerous
    other patents owned by SM Graphics’ affiliates. Floyd & Buss acted as counsel for SM
    Graphics until at least May 2011, logging more than 8,000 billable hours. The record is
    silent as to what role, if any, Floyd & Buss actually played in the settlement negotiations
    with Samsung.
    Matter No. 2: Floyd & Buss hired AlvaradoSmith in 2012 to arbitrate its
    claim for attorney fees against SM Graphics. Floyd & Buss alleged that SM Graphics
    underestimated the importance of the patents at issue in Matter No. 1 to the $45 million
    settlement, thereby reducing the amount owed to Floyd & Buss pursuant to a contingency
    agreement. Floyd & Buss obtained a cash payment of $3,501,000 from SM Graphics to
    settle this dispute; the arbitration was dismissed on November 12, 2013.
    Matter No. 3 (the instant action): Plaintiff (and real party in interest to this
    proceeding) Chitranjan N. Reddy sued defendants (and petitioners in this proceeding) SM
    Graphics and Acacia Patent Acquisition, LLC (Acacia Patent). Reddy claims defendants
    are alter egos of each other with regard to the allegations at issue. Reddy’s allegations
    are similar to those made by Floyd & Buss in Matter No. 2. Reddy was retained in
    March 2009 by Acacia Patent to perform expert consulting work relating to United States
    Patent Nos. 5,712,664 and 6,081,279, i.e., two of the patents owned by SM Graphics that
    2
    were ultimately made the subject of the litigation in Matter No. 1. The agreement
    Graphics retention agreement were not included within the scope of Matter No. 1.
    2
    According to Reddy’s operative complaint, he was the inventor of these
    patents, which he sold to Acacia Patent. The agreement required Reddy to be available
    for consultation on all matters related to these patents, to provide expert analysis of any
    reports or opinions provided by others concerning the patents, and to provide testimony
    when necessary in any litigation concerning the patents.
    3
    (styled a “Consulting Expert and Common Interest Agreement”) stated Reddy was
    entitled to 11 percent of the “Net Proceeds” of the “licensing, enforcement or sale” of the
    two patents. Reddy claims Acacia Patent and SM Graphics manipulated the settlement
    from Samsung to allocate an artificially low amount to the patents upon which Reddy
    provided his services. This resulted in a lower proposed payout to Reddy pursuant to his
    contingency agreement. Specifically, defendants allotted $1.5 million out of the $45
    million to SM Graphics, resulting in $93,289.59 being offered as payment to Reddy after
    3
    the deduction of alleged expenses.
    Reddy’s operative complaint includes causes of action for breach of
    contract, breach of the implied covenant of good faith and fair dealing, quantum meruit,
    an accounting, and violation of Business and Professions Code section 17200 et seq.
    Reddy asserts that defendants “acted with an intent to defraud Plaintiff when they entered
    into the contingency Consulting . . . Agreement. On information and belief, Defendants
    intended from the very beginning, but did not disclose to Plaintiff, that they would
    allocate the proceeds of any global settlement in a manner that favored Acacia [Patent’s]
    and its other affiliates’ interests to the detriment of Plaintiff by allocating settlement
    funds to multiple . . . related entities to avoid payment of the full contingency fees due.”
    Matter No. 3 was filed in San Luis Obispo County by Attorney Dawn Ceizler, a sole
    practitioner. But attorneys from AlvaradoSmith associated in as cocounsel after venue
    was transferred to Orange County and their successful representation of Floyd & Buss in
    Matter No. 2 ended.
    Acacia Patent and SM Graphics promptly moved to disqualify
    AlvaradoSmith in Matter No. 3, citing AlvaradoSmith’s access in Matter No. 2 to large
    quantities of confidential documents that would ordinarily be protected by the attorney-
    3
    Again, it is unclear whether Matter No. 1 concerned more than the two
    Reddy patents, and whether the $1.5 million allotted to SM Graphics is entirely
    attributable to the two Reddy patents.
    4
    client privilege and/or work product doctrine. Supporting declarations amply
    demonstrated that AlvaradoSmith had access to thousands of privileged documents
    produced during discovery in Matter No. 2. Indeed, defendants represent in their petition
    that “AlvaradoSmith obtained all of the [Floyd & Buss] files from” Matter No. 1. Work
    product prepared by Floyd & Buss in Matter No. 1 included a valuation of the claims
    against Samsung. Moreover, Reddy’s consulting agreement was drafted by Floyd &
    Buss, and privileged communications concerning Reddy’s consulting agreement were
    produced in discovery in Matter No. 2. A list of documents designated by Floyd & Buss
    for use at the arbitration included privileged communications and work product.
    Defendants’ moving papers, however, did not describe the precise contents of particular
    documents.
    In opposing the motion, AlvaradoSmith Attorney Marc Alexander declared
    that AlvaradoSmith abided by three separate protective orders governing confidential
    documents to which it had access during the arbitration in Matter No. 2. At the
    conclusion of Matter No. 2, AlvaradoSmith returned or destroyed confidential documents
    in its possession.
    The court denied the motion, reasoning: (1) AlvaradoSmith’s
    representation of Reddy was “not adverse, in the traditional sense,” to its representation
    of Floyd & Buss; (2) no improper acquisition of confidential information occurred in
    Matter No. 2; (3) protective orders required the return of all confidential documents at the
    end of Matter No. 2; (4) there is no evidence suggesting AlvaradoSmith violated the
    protective orders; and (5) mere exposure to confidential documents is insufficient to
    disqualify counsel. The court commented at the hearing, “I just don’t see that the
    privileged information that they may have come into knowledge of, . . . they no longer
    retained the files, so to retain that in their memory intact, [it would be] pretty difficult, I
    would imagine.”

    DISCUSSION
    “Generally, a trial court’s decision on a disqualification motion is reviewed
    for abuse of discretion. [Citations.] If the trial court resolved disputed factual issues, the
    reviewing court should not substitute its judgment for the trial court’s express or implied
    findings supported by substantial evidence. [Citations.] When substantial evidence
    supports the trial court’s factual findings, the appellate court reviews the conclusions
    based on those findings for abuse of discretion. [Citation.] However, the trial court’s
    discretion is limited by the applicable legal principles.” (People ex rel. Dept. of
    Corporations v. SpeeDee Oil Change Systems, Inc. (1999) 
    20 Cal. 4th 1135
    , 1143-1144.)
    The court’s explicit factual findings are supported by substantial evidence
    and the court’s chain of legal reasoning is largely sound. But we conclude the court erred
    and AlvaradoSmith must be disqualified based on the unique circumstances inherent to
    the representation of attorneys against their former clients (such as occurred here in
    Matter No. 2) and the substantial relationship between Matters No. 2 and 3.
    Successive Representation Conflicts Governed by “Substantially Related” Standard
    “Preserving confidentiality of communications between attorney and client
    is fundamental to our legal system. The attorney-client privilege is a hallmark of Anglo-
    American jurisprudence that furthers the public policy of insuring ‘“the right of every
    person to freely and fully confer and confide in one having knowledge of the law, and
    skilled in its practice, in order that the former may have adequate advice and a proper
    defense.” [Citation.]’ [Citation.] One of the basic duties of an attorney is ‘[t]o maintain
    inviolate the confidence, and at every peril to himself or herself to preserve the secrets, of
    his or her client.’ [Citation.] To protect the confidentiality of the attorney-client
    relationship, the California Rules of Professional Conduct bar an attorney from accepting
    ‘employment adverse to a client or former client where, by reason of the representation of
    6
    the client or former client, the [attorney] has obtained confidential information material to
    the employment except with the informed written consent of the client or former client.’”
    (In re Complex Asbestos Litigation (1991) 
    232 Cal. App. 3d 572
    , 586-587.)
    “For these reasons, an attorney will be disqualified from representing a
    client against a former client when there is a substantial relationship between the two
    representations. [Citations.] When a substantial relationship exists, the courts presume
    the attorney possesses confidential information of the former client material to the present
    representation.” (In re Complex Asbestos 
    Litigation, supra
    , 232 Cal.App.3d at p. 587.)
    In assessing whether there is a “substantial relationship” between two
    matters, courts “should ‘focus on the similarities between the two factual situations, the
    legal questions posed, and the nature and extent of the attorney’s involvement with the
    cases.’” (H. F. Ahmanson & Co. v. Salomon Brothers, Inc. (1991) 
    229 Cal. App. 3d 1445
    ,
    1455.) “The current matter is substantially related to the earlier matter if: [¶] (1) the
    current matter involves the work the lawyer performed for the former client; or [¶] (2)
    there is a substantial risk that representation of the present client will involve the use of
    information acquired in the course of representing the former client, unless that
    information has become generally known.” (Rest.3d Law Governing Lawyers, § 132.)
    Despite Floyd & Buss’s duties to preserve the confidentiality of SM
    Graphics’ privileged information, Floyd & Buss was entitled to reveal such information
    to AlvaradoSmith in Matter No. 2 to the extent necessary to litigate the action. (Evid.
    Code, § 958 [“There is no privilege under this article as to a communication relevant to
    an issue of breach, by the lawyer or by the client, of a duty arising out of the lawyer-
    client relationship”]; Dietz v. Meisenheimer & Herron (2009) 
    177 Cal. App. 4th 771
    , 786
    [“An attorney ‘can reveal confidences to defend against a malpractice claim or in a fee
    dispute’”].) But Floyd & Buss would not be entitled to represent a client in litigation
    against SM Graphics if such litigation were substantially related to Matter No. 1.
    7
    This is not a traditional successive representation case. The question is not
    whether Floyd & Buss can represent Reddy. Rather, the question is whether
    AlvaradoSmith should be disqualified from representing Reddy in Matter No. 3 based on
    its representation of Floyd & Buss in Matter No. 2. AlvaradoSmith never represented
    SM Graphics or Acacia Patent. The foregoing discussion does not mention any duty on
    the part of an attorney to maintain the confidences of a nonclient (let alone a litigation
    adversary), or any rationale for disqualifying attorneys from a matter based on their non-
    wrongful exposure to a litigation opponent’s privileged information. Viewed in general
    terms, these notions are seemingly opposed to basic principles of our adversarial system
    of justice. (See, e.g., Fox Searchlight Pictures, Inc. v. Paladino (2001) 
    89 Cal. App. 4th 294
    , 302-304 [disqualification not warranted based on exposure to opposing
    party’s privileged information by own client, who was an attorney suing her former
    employer for sex discrimination].)
    Some Representations Create Duties of Confidentiality to Nonclients
    There are exceptions, however, to the general rule that an attorney has no
    duty to preserve the confidences of nonclients. “A conflict of interest is involved if there
    is a substantial risk that the lawyer’s representation of the client would be materially and
    adversely affected by the . . . lawyer’s duties to another current client, a former client, or
    a third person.” (Rest.3d Law Governing Lawyers, § 121, italics added.) “A conflict of
    interest can . . . arise because of specific obligations, such as the obligation to hold
    information confidential, that the lawyer has assumed to a nonclient.” (Rest.3d Law
    Governing Lawyers, § 121, com. d, illus. 9, p. 253.)
    When do these obligations and duties to nonclients arise? Can conflicts
    based on duties to nonclients result in disqualification? Do courts apply the successive
    representation framework (i.e., the transfer of confidential information is presumed in a
    8
    substantially related matter) in these special cases where lawyers have duties of
    confidentiality to nonclients?
    We begin our inquiry into these questions with an examination of two cases
    highlighted by the parties. (See Kennedy v. Eldridge (2011) 
    201 Cal. App. 4th 1197
    (Kennedy); Morrison Knudsen Corp. v. Hancock, Rothert & Bunshoft (1999) 
    69 Cal. App. 4th 223
    (Morrison)). Neither is precisely on point. But both feature the
    disqualification of counsel despite the lack of an adverse representation or attorney
    4
    misconduct. And both cases endorsed the use of the successive representation
    framework in addressing disqualification motions brought by nonclients. Morrison and
    Kennedy show conflicts can arise in California (and disqualification motions can be
    granted) based on the conjunction of (1) implicit obligations a lawyer takes on to
    maintain the confidences of a nonclient received in the course of representing a client,
    and (2) the unfair advantage that might accrue were such a lawyer to pursue substantially
    related litigation against the nonclient.
    Kennedy involved a custody dispute in which the paternal grandfather (an
    attorney) sought to represent the father (i.e., the attorney’s son). 
    (Kennedy, supra
    , 201
    Cal.App.4th at p. 1200.) The trial court granted the mother’s motion to disqualify the
    paternal grandfather, even though neither he nor his wife (also an attorney) had ever
    represented the mother. (Id. at pp. 1201-1202.) The appellate court held that “an
    amalgamation of interrelated factors” supported the trial court’s exercise of discretion.
    4
    We are not primarily concerned here with cases in which an attorney
    commits wrongdoing and is disqualified on that basis. (See, e.g., Clark v. Superior Court
    (2011) 
    196 Cal. App. 4th 37
    , 41 [lawyer disqualified for receipt and excessive review of
    opponents privileged documents in violation of ethical duties].) It is conceded for
    purposes of this proceeding that AlvaradoSmith did not do anything wrong in Matter No.
    2 with regard to its possession and handling of defendants’ privileged documents.
    Moreover, there is substantial evidence for the court’s finding that AlvaradoSmith
    complied with all protective orders, which compliance included the return or destruction
    of all confidential documents obtained in Matter No. 2.
    9
    (Id. at p. 1205.) The first factor was the potential misuse of the mother’s confidential
    information, which the paternal grandparents “may have acquired” during the course of
    representing the mother’s father in a divorce proceeding. (Id. at pp. 1205-1206.) The
    close relationship between the mother and her father caused the court to treat the two
    individuals as “a single unity for purposes of determining whether an ethical conflict
    exists.” (Id. at p. 1208.) Kennedy applied the “substantial relationship” test from
    successive representation doctrine, and concluded “[t]he trial court could reasonably find
    there was a significant danger that — as a result of its prior involvement in her father’s
    divorce case — the [paternal grandparents’] firm acquired relevant confidential
    information about [the mother] to which it otherwise would not have had access.” (Id. at
    p. 1207.) Kennedy noted that the “successive representation model” does not require
    proof of the receipt of confidential information because such transfer of confidences is
    presumed. (Id. at p. 1208.) Other factors supporting the court’s ruling included the
    possibility that the paternal grandfather would need to testify in the custody dispute (
    id. at p.
    1209), as well as the “strong appearance of impropriety” caused by the “multiple and
    interconnected family entanglements” between the parties and proposed counsel. (Id. at
    p. 1211.)
    Kennedy is not particularly apt as authority here because its holding was
    tethered to messy interfamilial squabbles and was not based solely on the receipt of
    confidential information. Kennedy is also a case in which the trial court disqualified
    counsel and the appellate court affirmed the disqualification under an abuse of discretion
    standard. Here, of course, we must decide whether the trial court had discretion to deny
    the motion for disqualification.
    In Morrison, a law firm sought to represent a water district in litigation
    against a construction firm’s subsidiary. 
    (Morrison, supra
    , 69 Cal.App.4th at pp. 226-
    228.) The law firm was already working for the construction firm’s insurance
    underwriters; “[i]n its capacity as ‘monitoring counsel,’ [the law firm] received detailed
    10
    confidential communications from [the construction firm’s] defense counsel concerning
    the progress of cases and [the construction firm’s] potential liability.” (Id. at p. 227.)
    The construction firm and its subsidiary moved to disqualify the law firm from
    representing the water district by way of a motion for preliminary injunction. The trial
    court granted the motion based on the presumption that the law firm possessed
    confidential information, and the appellate court affirmed. (Id. at pp. 228-229, 253-254.)
    The construction firm had a “reasonable expectation” that its confidences, transferred to
    counsel for its insurer, would be maintained. (Id. at p. 233.) The law firm’s duty to
    maintain these confidences “stemmed from its client’s duty of good faith to an insured,
    and thus, ultimately, from [the law firm’s] loyalty to the underwriters, not [the
    5
    construction firm].” (Id. at p. 234.) Morrison applied the “substantial relationship” test
    from successive representation cases to judge whether the particular confidences received
    required disqualification, and concluded substantial evidence supported the trial court’s
    disqualification decision. (Morrison, at p. 234.)
    Morrison certainly can be analogized to the facts of this case, though
    (unlike here) one would not say disqualified counsel in Morrison was adverse to the
    nonclient in both matters. Had the trial court opted to disqualify AlvaradoSmith,
    Morrison would provide powerful support for a conclusion that such an order was within
    the court’s discretion. (See 
    Morrison, supra
    , 69 Cal.App.4th at p. 253 [“what may have
    been a difficult decision for the trial court is ultimately, by virtue of the limited scope of
    review, not a close one on appeal”].) Like Kennedy, however, the different procedural
    5
    This point is consistent with commentary discussing one doctrinal source
    for a lawyer’s duties to a non-client: “A lawyer might have obligations to persons who
    were not the lawyer’s clients but about whom information was revealed to the lawyer
    under circumstances obligating the lawyer not to use or disclose the information. Those
    obligations arise under other law, particularly under the law of agency. For example, a
    lawyer might incur obligations of confidentiality as the subagent of a principal whom the
    lawyer’s client serves as an agent . . . .” (Rest. 3d Law Governing Lawyers, § 132, com.
    (g)(ii), p. 384.)
    11
    posture in Morrison means it cannot be taken as authority for the proposition that we
    must grant relief to Acacia Patent and SM Graphics. Neither of the California cases
    primarily relied on in the petition provides a clear answer to the question presented.
    Consistent with these cases, and somewhat closer to the facts here, Burkes
    v. Hales (Wis. Ct.App. 1991) 
    478 N.W.2d 37
    (Burkes) explores an attorney’s duties to
    the clients of the attorney’s law firm client. In Burkes, Burkes sued Hales and other
    members of the Wisconsin Investment Board for wrongful discharge from his position as
    executive director. (Id. at p. 38.) The Fox firm represented Burkes and the state Attorney
    General represented Hales. (Id. at p. 39.) While the litigation was pending, a contingent
    of lawyers at the Fox firm departed, taking Burkes’s file with them. (Ibid.) The
    remaining Fox firm partners hired attorney Hurley to represent them in a lawsuit
    concerning the Fox firm’s break up. (Ibid.) The Fox firm dispute settled, with the Fox
    firm retaining a financial interest in Burke’s action as part of the settlement. (Ibid.) “At
    about the same time, the attorney general . . . withdrew . . . and the governor appointed
    Hurley as special counsel to represent Hales.” (Ibid.) The trial court granted Burkes’s
    disqualification motion and the appellate court affirmed the court’s exercise of discretion.
    (Id. at pp. 39, 43.)
    Burkes first held that Hurley had an implied fiduciary duty to the Fox
    firm’s “clients whose files are part and parcel of the intrafirm litigation.” 
    (Burkes, supra
    ,
    478 N.W.2d at p. 41.) “We have no doubt that, as Burkes’s attorney, the Fox firm had a
    fiduciary duty to him. And we agree with the trial court that Hurley, once retained by the
    Fox firm, undertook a similar duty and became bound by the same proscriptions as the
    firm itself with regard to Burkes.” (Ibid., fn. omitted.) Burkes then held there was a
    substantial relationship between the two representations because one of Hurley’s tasks in
    the Fox firm litigation was to protect the Fox firm’s interest in the Burkes litigation. (Id.
    at p. 42.) The court rejected Hurley’s argument that he could “avoid disqualification by
    proving that no confidences were actually shared.” (Ibid.) “The test is whether the
    12
    lawyer ‘could have obtained’ confidential information in the first representation that
    would have been relevant in the second; whether such information actually was obtained
    and, if so, whether it actually was used against the former client is irrelevant.” (Ibid.)
    In sum, disqualifying conflicts with nonclients can arise as a result of an
    attorney-client relationship. If an attorney is deemed to have a duty of confidentiality to a
    nonclient arising out of such a past representation, courts apply the substantial
    relationship test from successive representation doctrine to determine whether to
    disqualify counsel in a case against the nonclient.
    Prior Representation of Attorney Parties against Their Own Clients
    California case law does not discuss the precise issue before us — whether
    a law firm’s representation of a lawyer in a fee dispute results in a disqualifying conflict
    of interest when the law firm opposes the fee dispute defendant in another matter. This
    fact pattern includes elements of cases like Morrison and Burkes (i.e., the assumption of a
    client’s duties of confidentiality to a nonclient may provide grounds for disqualification
    in a subsequent matter against the nonclient). But a wildcard is added to the mix: the
    supposed duty of confidentiality here would be owed to a party that was adverse to
    AlvaradoSmith’s clients in both the prior and subsequent litigation.
    A limited universe of out-of-state cases has addressed the prospect of a duty
    of confidentiality to a litigation adversary arising by way of representing a law firm
    against that adversary in a different action. Several courts have disqualified attorneys for
    simultaneously representing a nonclient’s litigation opponent and the nonclient’s former
    law firm in a malpractice action arising out of the same litigation. (Frye v. Ironstone
    Bank (Fla. Ct.App. 2011) 
    69 So. 3d 1046
    ; Adelman v. Adelman (Fla. Ct.App. 1990) 
    561 So. 2d 671
    ; Greig v. Macy’s Northeast (N.J.Dist.Ct. 1998) 
    1 F. Supp. 2d 397
    .) Of course,
    if the malpractice case is not substantially related to the other matter and there is no
    specific showing that pertinent privileged information was communicated,
    13
    disqualification is not appropriate. (See Miccosukee Tribe of Indians v. Lehtinen (Fla.
    Ct.App. 2013) 
    114 So. 3d 329
    [declining to disqualify attorney in malpractice defense
    case based on speculation he could obtain confidential information to use in other
    unrelated matters against plaintiff].)
    As to fee disputes, several federal courts have rejected the argument that an
    attorney fee dispute is substantially related, per se, to the litigation in which the fees arose
    such that disqualification is required. In T.C. Theatre Corp. v. Warner Bros. Pictures
    (S.D.N.Y. 1953) 
    113 F. Supp. 265
    , a variety of disqualification motions were brought by
    defendants in an antitrust case. The basis for the motions was that one of the plaintiff’s
    attorneys, Cooke, previously represented one of the defendants in a substantially related
    matter brought by the federal government. (Id. at pp. 266-271.) The district court
    granted the motion to disqualify Cooke. (Id. at p. 271.) Defendants also sought to
    disqualify another firm representing the plaintiff in the antitrust case because it
    represented Cooke in a fee collection action arising out of the prior substantially related
    government antitrust case. (Id. at pp. 271-272.) The court refused to disqualify the firm,
    observing that “Cooke’s right to recovery of additional fees . . . does not depend upon the
    disclosure of confidential communications, but, rather, upon the nature, extent and
    importance of the services performed by him. He could enumerate the various
    conferences with his client without detailing the matters which might have been
    discussed.” (Ibid.; 
    id. at p.
    272 [refusing to assume that Cooke “divulged confidences
    reposed in him by his former clients simply because he is now engaged in a law suit with
    them”].)
    Lankler Siffert & Wohl, LLP v. Rossi (S.D.N.Y. 2003) 
    287 F. Supp. 2d 398
    was a fee collection action brought by a law firm and various expert witnesses against
    their former clients. The district court refused to disqualify the law firm from
    representing itself or the expert witnesses in the fee dispute. (Id. at pp. 403-407.) The
    Lankler court rejected the contention that the underlying criminal defense and the fee
    14
    dispute were substantially related. (Id. at pp. 404-405.) And the Lankler court found
    insufficient evidence for the proposition that the law firm had been representing
    defendants in contesting the expert fee amounts with the experts or the defendants’
    insurance company during the underlying litigation. (Id. at pp. 405-406; see also Gross
    Belsky Alonso LLP v. Edelson (N.D.Cal., May 27, 2009, No. C 08-4666 SBA) 2009
    U.S.Dist. Lexis 49260 [refusing to disqualify law firm from representing itself in fee
    collection action based on argument that matters were substantially related].)
    We find these out-of-state authorities persuasive for the general principle of
    law that a disqualifying conflict can arise, with regard to an adverse non-client, by way of
    a law firm representing another law firm. However, consistent with these cases, it does
    not end the discussion to observe that AlvaradoSmith represented SM Graphics’s former
    attorneys in Matter No. 2 and now seeks to oppose SM Graphics and Acacia Patent in
    Matter No. 3. A lawyer representing a law firm in a fee dispute is not automatically
    disqualified from opposing the defendant client in future litigation, even in future
    litigation that has some factual nexus with the prior litigation. Rather, a court must
    examine (1) whether the first representation resulted in a broad disclosure of the non-
    client’s privileged information (i.e., something beyond the attorney-client retainer
    agreement and the number of hours worked), and (2) whether a substantial relationship
    exists between the two matters. Not every attorney fee dispute results in the law firm
    plaintiff’s counsel receiving broad access to privileged information from the underlying
    dispute. Nor will every attorney fee dispute be substantially related to a subsequent
    action against the same non-client.
    The Circumstances Require the Disqualification of AlvaradoSmith
    We conclude disqualification is necessary under the circumstances of this
    case. The court erred because: (1) SM Graphics’ extensive privileged information
    pertaining to Matter No. 1 was made available to AlvaradoSmith in Matter No. 2; and (2)
    15
    there is a substantial relationship between Matters No. 2 and No. 3. To the extent
    findings to the contrary should be implied in our review of the court’s order, such
    findings were an abuse of discretion because they are not supported by substantial
    evidence.
    AlvaradoSmith had access to numerous privileged documents in Matter No.
    2 because the nature of the litigation in Matter No. 2 required it. Evidence submitted
    with defendants’ motion to disqualify established the extent of this exposure. Some of
    these documents pertained to Reddy’s consulting agreement and a valuation of the claims
    against Samsung. This is not a case in which a court could plausibly find that Floyd &
    Buss refrained from disclosing privileged documents in Matter No. 2 or disclosed only
    privileged documents narrowly pertaining to the number of hours worked in Matter
    6
    No. 1.
    6
    Reddy contends Neal v. Health Net, Inc. (2002) 
    100 Cal. App. 4th 831
    (Neal) supports his position. In Neal, an attorney filed a discrimination case on behalf of
    a former employee (Neal) of the defendant employer. (Neal, at p. 834.) Two months
    later, the same attorney agreed to represent another former employee (Brockett) of the
    same employer. (Id. at pp. 834-836.) Before her employment terminated, Brockett, a
    legal secretary, had access to employer’s legal files and had in fact opened the electronic
    Neal file, which included “attorney notes and memoranda.” (Ibid.) Brockett claimed in
    her declaration that she had accessed this file only to obtain the name of Neal’s attorney,
    and that she did not actually review documents pertinent to Neal’s case. (Id. at pp. 836-
    837.) Employer filed a motion to disqualify the attorney in the Neal case based on the
    theory that he presumably had received confidential information from Brockett about the
    Neal case. (Id. at pp. 834-837.) The appellate court reversed the order of
    disqualification. (Id. at p. 850.) There is no “presumption of possession of confidential
    information” in these circumstances. (Id. at p. 841.) And there was no evidence
    submitted showing that “information, confidential or otherwise, concerning [Neal’s] case
    was given to [the attorney] by Ms. Brockett.” (Id. at p. 843.)
    Referencing Neal in the present circumstances is inapt. The
    disqualification motion in Neal was dependent on the assumption that Neal’s lawyer
    wrongfully obtained privileged information about Neal’s case from his client, Brockett,
    an accusation denied in declarations filed by Neal’s attorney and Brockett. 
    (Neal, supra
    ,
    100 Cal.App.4th at pp. 836, 839, 843.) Moreover, as explained by Neal in its canvassing
    of California law, a lawyer’s “mere exposure” to confidential information by an ex-
    16
    As to substantial similarity, a few differences between Matter No. 2 (the
    Floyd & Buss arbitration) and Matter No. 3 (Reddy’s lawsuit) can be found. There are
    two separate contingency agreements at issue relating to two separate functions, that of
    attorney and that of expert consultant. Reddy’s work was clearly limited to two patents,
    while Floyd & Buss agreed to pursue litigation claims regarding 14 patents. Alter ego is
    pleaded in the instant action with regard to the relationship between Acacia Patent and
    SM Graphics but not in Matter No. 2. Defenses against an attorney fee collection action
    7
    and a consultant’s fee collection action might differ.
    But these differences pale in comparison with the essential similarities
    between Matters No. 2 and No. 3. Both contingency agreements pertain to the potential
    recovery in Matter No. 1. Both Floyd & Buss and Reddy allege that SM Graphics (as
    well as its affiliate, Acacia Patent, in this case) manipulated the settlement in Matter No.
    1 to shortchange their recoveries. Relevant issues in both matters include defendants’
    intent in structuring the contingency agreements (rather than paying hourly fees) and in
    dividing the proceeds of the Samsung settlement between various affiliates in petitioners’
    corporate family. The similarity of the legal and factual issues in Matters No. 2 and No.
    3 distinguishes the instant action from standard, hourly rate fee dispute cases, which
    employee client of a litigation adversary does not provide grounds for disqualification.
    (Id. at p. 843.) The instant case is fundamentally different. It is undisputed that
    AlvaradoSmith properly accessed SM Graphics’s privileged information in the course of
    litigating a prior matter, bringing this case within the framework of successive
    representation cases. There is no factual dispute here that AlvaradoSmith extensively
    reviewed SM Graphics’ privileged documents in the ordinary course of representing
    Floyd & Buss in Matter No. 2. This is not a case in which AlvaradoSmith might or might
    not have been exposed to SM Graphics’ confidential information in a private counseling
    session with its client.
    7
    We decline to consider an issue only hinted at in the petition and elsewhere
    in the record, to wit, the potential illegality of Reddy’s contingency arrangement with
    Acacia Patent. This issue is not sufficiently briefed to address it on the merits.
    17
    might not be substantially related to the underlying action or to other fee disputes. Any
    privileged information Floyd & Buss received with regard to the valuation of the Reddy
    patents vis-à-vis Samsung, or even more general insights into the internal operations of
    SM Graphics and its affiliates, are relevant to this action in a way it would not be in a
    straight fee recovery based on the number of hours worked. The extra issues here (e.g.,
    the alter ego component) do not undermine the similarity of the main question in both
    8
    matters.
    Under these circumstances, it is unnecessary for a party seeking
    disqualification to pinpoint precise privileged documents as the basis for a potential
    unfair advantage. Like successive representation cases, the better rule here is to presume
    the possession of material confidential information and disqualify counsel in a
    substantially related action. “The conclusive presumption of knowledge of confidential
    information has been justified as a rule of necessity, ‘for it is not within the power of the
    [party seeking disqualification] to prove what is in the mind of the attorney. Nor should
    the attorney have to “engage in a subtle evaluation of the extent to which he acquired
    relevant information in the first representation and of the actual use of that knowledge
    and information in the subsequent representation.”’ [Citations.] The conclusive
    presumption also avoids the ironic result of disclosing the former client’s confidences and
    secrets through an inquiry into the actual state of the lawyer’s knowledge and it makes
    clear the legal profession’s intent to preserve the public’s trust over its own self-interest.”
    (H. F. Ahmanson & Co. v. Saloman Brothers, 
    Inc., supra
    , 229 Cal.App.3d at p. 1453.)
    8
    We reject the notion that because Reddy may have been exposed to some of
    defendants’ privileged information in the course of his expert consulting work, there is no
    problem with allowing AlvaradoSmith to represent both Floyd & Buss and Reddy. It is
    unreasonable to infer from the record before us that Reddy would have access to
    privileged documents on all topics, as opposed to information and documents necessary
    for his expert consulting work.
    18
    It was perfectly legitimate for Floyd & Buss, as well as AlvaradoSmith, to
    use every piece of information available in Matter No. 2, regardless of whether it was
    subject to the attorney-client privilege or work product protection. The same thing
    cannot be said about Matter No. 3. It is not viable to suppose AlvaradoSmith can honor
    its duty to maintain the confidences of Floyd & Buss’s client SM Graphics in the course
    of representing Reddy. Less restrictive alternatives to disqualification, such as protective
    orders, do not address the fundamental problem with AlvaradoSmith’s representation of
    Reddy. As stated in the petition, “[e]ven the strongest protective order cannot . . . make
    AlvaradoSmith forget what it has learned or ensure that AlvaradoSmith can remember
    9
    and distinguish between what was privileged and what was not.”
    We acknowledge the downside to this result. It is possible that the
    privileged information to which AlvaradoSmith had access in Matter No. 2 would not
    provide them with any advantage in this action. It is possible that the disqualification of
    AlvaradoSmith will serve only as a tactical victory for defendants. It is possible an
    injustice is being done to both Reddy and AlvaradoSmith by disqualifying Reddy’s
    chosen counsel. But we must subordinate these concerns to the more serious danger of a
    litigant’s privileged information, disclosed to its own attorney (Floyd & Buss) in an
    earlier matter (Matter No. 1), being used against it. (See People ex rel. Dept. of
    9
    Reddy posits that any theoretical insights that might have been gained from
    privileged information in Matter No. 2 cannot be of any practical use to AlvaradoSmith
    in Matter No. 3, because the attorney-client privilege would prevent production of
    privileged documents or testimony concerning privileged communications. But, to
    illustrate why this argument is untrue, imagine a privileged, “smoking gun” email exists
    that would prove Reddy’s allegations. Imagine further that this document was reviewed
    by AlvaradoSmith in the course of Matter No. 2. Just knowing that there is merit to
    Reddy’s allegations would be extremely valuable in crafting litigation strategy and
    settlement negotiation positions, regardless of whether this particular email could be
    obtained in discovery or used as an exhibit at trial. Now, perhaps it is unrealistic to
    postulate a true “smoking gun” in the context of this case. Even so, the essential point
    holds true: there is litigation value to information, even if that information cannot be
    directly converted into admissible evidence.

    Corporations v. SpeeDee Oil Change Systems, 
    Inc., supra
    , 20 Cal.4th at p. 1145 [“The
    paramount concern must be to preserve public trust in the scrupulous administration of
    justice and the integrity of the bar. The important right to counsel of one’s choice must
    yield to ethical considerations that affect the fundamental principles of our judicial
    process”].)
    We conclude by noting “our analysis does not mean that there is or should
    be any broad duty owed by an attorney to an opposing party to maintain that party’s
    confidences in the absence of a prior attorney-client relationship. The imposition of such
    a duty would be antithetical to our adversary system and would interfere with the
    attorney’s relationship with his or her own clients. The courts have recognized
    repeatedly that attorneys owe no duty of care to adversaries in litigation or to those with
    whom their clients deal at arm’s length. [Citations.] Instead, we deal here with a
    prophylactic rule necessary to protect the confidentiality of the attorney-client
    relationship and the integrity of the judicial system . . . .” (In re Complex Asbestos
    
    Litigation, supra
    , 232 Cal.App.3d at p. 588.) In the limited realm of cases featuring
    attorneys as parties opposed to their former clients, lawyers representing the attorney
    party must avoid participation in substantially related matters, whereby their access to
    privileged information in the former action would potentially serve as an advantage in the
    latter. The court did not have discretion to deny the disqualification motion on this
    record.
    DISPOSITION
    Let a peremptory writ of mandate issue directing the court to vacate its
    order of April 14, 2014 and to enter a new and different order disqualifying
    AlvaradoSmith from its representation of plaintiff Reddy. The stay order is hereby lifted.
    20
    The order to show cause is discharged. Petitioners SM Graphics and Acacia Patent shall
    recover costs incurred in this writ proceeding.
