    S YKES, Circuit Judge. This case arises out of a complex
    set of contractual relationships between the Wisconsin
    Alumni Research Foundation, the patent-management
    entity for the University of Wisconsin; certain research

    scientists at the University; and Xenon Pharmaceuticals, a
    Canadian drug company. The Foundation and Xenon
    jointly own the patent rights to an enzyme that can lower
    cholesterol levels in the human body. The enzyme’s
    cholesterol-reducing benefits were discovered and con-
    firmed by scientists at the University whose research
    was sponsored in part by Xenon. In 2001, pursuant to an
    option agreement between the Foundation and Xenon,
    the Foundation gave Xenon an exclusive license to com-
    mercialize this discovery and market any resulting prod-
    ucts in exchange for a share of the profits.
    The Foundation brought this suit against Xenon
    alleging violations of its contract rights and seeking
    damages and declaratory relief. First, the Foundation
    alleged that Xenon sublicensed its interest in the patented
    enzyme to a third party but refused to pay the Founda-
    tion a percentage of the sublicense fees as required under
    the 2001 license agreement. Second, the Foundation
    alleged that Xenon wrongly asserted ownership over a
    set of therapeutic compounds developed from the jointly
    patented enzyme; the Foundation claimed that it owned
    rights to these compounds pursuant to its network of
    written agreements with Xenon and the University re-
    searcher who confirmed the therapeutic benefits of the
    compounds. Xenon counterclaimed against the Founda-
    tion, and on cross-motions for summary judgment,
    the district court ruled in the Foundation’s favor on the
    breach-of-contract claim and in Xenon’s favor on the
    dispute over ownership of the compounds. A jury awarded
    $1 million in damages for the breach of contract; the
    Foundation accepted $300,000 after Xenon successfully
    moved for remittitur. Both parties appealed.
    Nos. 08-1351 & 06-3901                                  3
    We affirm in part and reverse in part and remand
    for entry of judgment consistent with this opinion. The
    district court properly granted summary judgment for
    the Foundation on the breach-of-contract claim. Xenon
    breached its license agreement with the Foundation by
    granting a sublicense in the jointly patented enzyme to a
    third party without paying the Foundation its share of
    the sublicense fees. A subsidiary issue is whether
    Xenon’s breach triggered the Foundation’s right to termi-
    nate the agreement. We conclude that the district court
    should not have voided the Foundation’s attempt to
    do so; the Foundation was entitled to and properly termi-
    nated the agreement. We also conclude the district court
    erroneously entered judgment for Xenon on the issue of
    the Foundation’s claim to an ownership interest in the
    compounds. Under the web of contracts at issue here,
    the Foundation was entitled to a declaration of its owner-
    ship interest in the compounds.
    I. Background
    Researchers at the University of Wisconsin became
    interested in an enzyme called Stearoyl CoA Desaturase
    (“SCD”) because of its potential to help treat diabetes,
    obesity, and other diseases by lowering cholesterol. In
    1999 the researchers discovered that suppressing SCD
    levels in the human body lowered cholesterol levels.
    Pursuant to University policy, the researchers dis-
    closed their research results to the Foundation and in
    January 2000 signed a Memorandum Agreement
    assigning all their rights in the discovery to the Founda-
    4                                     Nos. 08-1351 & 06-3901
    tion. The next month, the Foundation filed a provisional
    patent application for the discovery.
    Meanwhile, Xenon, a Canadian pharmaceutical
    company that was collaborating with the University on
    research into a separate enzyme, learned of the Univer-
    sity’s discoveries and expressed interest in jointly
    pursuing SCD research. The University and Xenon
    entered into a series of research agreements (referred to
    as Research Agreements 1, 2, and 3) in which Xenon
    agreed to jointly sponsor various SCD research projects
    with the University. Each research agreement identified
    the scope of the research, the principal researcher, the
    expected cost, and the period of performance.1 These
    agreements also referred to a separate Sponsor Option
    Agreement between the Foundation and Xenon that
    governed ownership of any discoveries arising from the
    joint research program. The Sponsor Option Agreement
    cross-referenced the contracts between the Foundation
    and the individual University researchers requiring the
    researchers to assign to the Foundation any property
    rights in the discoveries emanating from the research and
    gave Xenon an exclusive option to license any resulting
    1
    The joint research program ran into problems in November
    2002 when Xenon and the University became embroiled in a
    funding dispute. The University claimed that Xenon had
    fallen behind on payments for the sponsored research, and as
    a result the University had to turn to federal funds to fill the
    gap. Xenon denied that it owed the University any additional
    money. A year later, Xenon and the University settled this
    dispute and signed a Settlement and Release Agreement.
    Nos. 08-1351 & 06-3901                                   5
    technology.2 Attached to the Sponsor Option Agreement
    were the individual contracts between the Foundation
    and the University researchers.
    At the same time that Xenon signed its first research
    agreement with the University, Xenon also entered into
    a series of short-term consulting agreements with individ-
    ual researchers at the University who worked on SCD
    projects. In exchange for consulting fees, these scientists
    undertook specific research projects for Xenon and agreed
    to assign any discoveries arising from these consulting
    projects to Xenon.
    In February 2001 Xenon and the Foundation filed a
    joint patent application deriving from the provisional
    patent application the Foundation had filed in 2000. The
    application covered, among other things, the SCD enzyme
    itself and a method (called an assay) of using the enzyme
    to identify compounds that lower SCD levels. A patent
    issued for the assay, but the patent application covering
    the remaining claims is still pending. Also in
    February 2001, Xenon exercised its option under the
    Sponsor Option Agreement to an exclusive license for
    any discoveries arising from the Xenon-sponsored SCD
    research at the University. As a result Xenon and the
    Foundation entered into an Exclusive License Agree-
    ment giving Xenon an exclusive right to make, use, and
    sell patented products under the joint patent application
    within the field of human healthcare. In exchange for
    2
    The Sponsor Option Agreement was executed in February
    2000 but backdated to September 1999.
    6                                  Nos. 08-1351 & 06-3901
    these exclusive rights, Xenon agreed to pay the Founda-
    tion a percentage of any product sales, royalties, or
    sublicense fees it received.
    After receiving the exclusive license, Xenon worked
    with Discovery Partners, Inc., to help identify compounds
    that inhibit the SCD enzyme. Using the jointly patented
    assay, Discovery Partners screened thousands of com-
    pounds and identified a set of 20 (referred to as the PPA
    compounds) with the potential to suppress SCD levels.
    Xenon shipped the PPA compounds to Mark Gray-Keller,
    a University researcher with whom it had a consulting
    agreement, for confirmatory testing. Gray-Keller success-
    fully confirmed the inhibitory potential of the PPA com-
    pounds and thereafter assigned any interest he had in
    the compounds to Xenon. In 2002 Xenon filed a patent
    application covering the PPA compounds.
    The Foundation objected, claiming that it had an owner-
    ship interest in the PPA compounds under the various
    interlocking agreements among the parties. More specifi-
    cally, the Foundation noted that Gray-Keller had
    assigned all his rights in SCD discoveries and any improve-
    ments to the Foundation in his 2000 Memorandum Agree-
    ment. The Foundation also noted that the Sponsor Option
    Agreement between it and Xenon specifically acknowl-
    edged that Gray-Keller was required to assign his
    interest in any inventions arising from the jointly spon-
    sored research to the Foundation. Alternatively, the
    Foundation claimed it had title to the compounds under
    the Bayh-Dole Act, 
    35 U.S.C. §§ 200
     et seq., because
    federal funds had been used in the research and develop-
    ment of the compounds.
    Nos. 08-1351 & 06-3901                                    7
    Relations between Xenon and the Foundation con-
    tinued to deteriorate in 2004 when Xenon signed a
    license agreement with Novartis Pharma AG (“Novartis”),
    a Swiss corporation. This agreement gave Novartis a
    license to the technology covered by the joint patent
    application and purported to transfer ownership of the
    PPA compounds. After learning of this agreement (via a
    press release), the Foundation demanded a percentage
    of the sublicense fees from Xenon under the terms of the
    Exclusive License Agreement. Xenon refused, claiming it
    had the right to license its undivided interest in the joint
    patent application without being subject to the terms of
    its license agreement with the Foundation.
    The Foundation then brought this suit claiming that
    Xenon violated the terms of the Exclusive License Agree-
    ment and owed the Foundation a percentage of the
    sublicense fees it received from Novartis. The Foundation
    also claimed that it, not Xenon, owned Gray-Keller’s
    interest in the PPA compounds. The Foundation sought
    damages and declaratory judgment. Xenon responded
    with counterclaims against the Foundation. The district
    court, on cross-motions for summary judgment, entered a
    series of rulings on all issues except damages. The
    judge held that Xenon breached the Exclusive License
    Agreement by granting a sublicense to Novartis without
    notifying the Foundation or conforming the sublicense
    to the terms set out in the license agreement. The judge
    also held that Xenon owed royalties or sublicense fees
    to the Foundation under the terms of the license agree-
    ment. The judge further held that in light of Xenon’s
    breach, the Foundation had a right to terminate the
    license agreement.
    8                                  Nos. 08-1351 & 06-3901
    The court also ruled in Xenon’s favor on several issues.
    First, the judge dismissed as moot the Foundation’s claim
    that Xenon breached its duty of good faith by failing to
    abide by the terms of the license agreement. Second, the
    judge held that the Foundation had not given Xenon
    proper notice or an opportunity to cure before invoking
    its right to terminate the license agreement. Third, the
    court denied the Foundation’s claims to quiet title in
    the PPA compounds, for conversion of those same com-
    pounds, and for a declaratory judgment that Gray-
    Keller’s purported assignment of his rights in the com-
    pounds to Xenon was void. The court held that the Foun-
    dation could not claim title to the compounds under
    either the Memorandum Agreement with Gray-Keller, the
    Sponsor Option Agreement with Xenon, or the Bayh-Dole
    Act. Later, the court vacated its ruling regarding the
    Foundation’s right to terminate the license agreement;
    the judge agreed with Xenon that the Foundation had
    not properly developed this argument in its opening
    summary-judgment brief.
    The case proceeded to a jury trial on the question of
    damages for Xenon’s failure to pay royalties or
    sublicense fees. The jury awarded $1 million, but on
    Xenon’s motion for remittitur the court reduced the
    award to $300,000, which the Foundation accepted. The
    parties cross-appealed from the judgment, challenging
    various of the district court’s rulings on summary judg-
    ment; Xenon also challenges the sufficiency of the
    evidence on damages.

    II. Discussion
    We review the district court’s grant of summary judg-
    ment de novo. Clancy v. Geithner, 
    559 F.3d 595
    , 599 (7th
    Cir. 2009). Summary judgment is appropriate when there
    is no genuine issue of material fact and the moving party
    is entitled to judgment as a matter of law. See F ED. R. C IV.
    P. 56(c). On review of cross-motions for summary judg-
    ment, we view all facts and inferences in the light most
    favorable to the nonmoving party on each motion. See
    Tate v. Long Term Disability Plan for Salaried Employees of
    Champion Int’l Corp. #506, 
    545 F.3d 555
    , 559 (7th Cir.
    2008). For organization and ease of discussion, we divide
    the issues on appeal into two groups: (1) those that relate
    to the rights of the parties under the Exclusive License
    Agreement, and (2) those that relate to the rights of the
    parties regarding the PPA compounds.
    A. Exclusive License Agreement
    1. Xenon’s Transfer of Rights to Novartis
    We begin by addressing Xenon’s contention that it did
    not violate the terms of the Exclusive License Agree-
    ment when it licensed its interest in the joint patent
    application to Novartis without paying the Foundation
    its share of the licensing fee. As a threshold matter, Xenon
    argues that this dispute is resolved by federal patent law,
    not by contract law. The district court did not address
    the question whether Xenon retained a federal statutory
    right to freely license its interest without regard to the
    Foundation’s contract rights. The court resolved the
    10                                  Nos. 08-1351 & 06-3901
    parties’ disputes based solely on the terms of their
    various contracts, holding that Xenon effectively executed
    a sublicense with Novartis and that this transaction
    fell within the provision of the Exclusive License Agree-
    ment governing sublicenses. Xenon contends that federal
    law—specifically, 
    35 U.S.C. § 262
    —gives it the right to
    freely license its undivided one-half interest in the joint
    patent application without accounting to the Foundation
    under the terms of the Exclusive License Agreement.
    We disagree.
    Federal law provides that joint patent owners, like the
    Foundation and Xenon, have control over the entire
    property, and each co-owner may freely use the
    patented technology without regard to the other. See 
    35 U.S.C. § 262
    . We have previously observed that under
    this principle of patent law, “each co-owner is ‘at the
    mercy’ of the other in that the right of each to license
    independently ‘may, for all practical purposes, destroy
    the monopoly and so amount to an appropriation of the
    whole value of the patent.’ ” Rail-Trailer Co. v. ACF Indus.,
    Inc., 
    358 F.2d 15
    , 17 (7th Cir. 1966) (quoting Talbot v.
    Quaker-State Oil Ref. Co., 
    104 F.2d 967
    , 968 (3d Cir. 1939)).
    This statutory rule is subject to an important exception,
    however: Joint patent owners may vary their rights by
    contract. The statute provides that “[i]n the absence of any
    agreement to the contrary, each of the joint owners of a
    patent may make, use, offer to sell, or sell the
    patented invention . . . without the consent of and without
    accounting to the other owners.” 
    35 U.S.C. § 262
     (emphasis
    added). The statutory default rule therefore controls
    unless there is an agreement to the contrary.
    Nos. 08-1351 & 06-3901                                    11
    Here, the Foundation and Xenon modified the
    statutory default rule by contract; the Exclusive License
    Agreement plainly qualifies as “an agreement to the
    contrary” for purposes of § 262. That agreement provides:
    “[The Foundation] hereby grants to Xenon an exclusive
    license, limited to the [field of human healthcare,] . . .
    under the Licensed Patents to make, use and sell Prod-
    ucts.” In exchange Xenon agreed to pay the Foundation a
    percentage of any payments, royalties, or sublicense fees
    it received by commercializing the technology itself or
    sublicensing the technology to a third party to commer-
    cialize. Under the terms of the agreement, sublicenses
    are expressly permitted—provided Xenon pays the Founda-
    tion the specified percentage of any royalties or sub-
    license fees—but assignments are prohibited without the
    Foundation’s prior written consent.3
    Xenon argues that nothing in the Exclusive License
    Agreement explicitly revokes its statutory right to license
    its interest freely. True, but the agreement’s provision
    requiring that Xenon pay the Foundation a share of the
    fees derived from any sublicense plainly undermines
    Xenon’s claim that it retained an unfettered right under
    § 262 to transfer its interest in the technology to third
    parties. So does the agreement’s provision prohibiting
    assignment of the license without the Foundation’s con-
    3
    The Exclusive License Agreement states: “This Agreement is
    not assignable by either party except with the prior written
    consent of the other party, which consent shall not be unrea-
    sonably or arbitrarily withheld.”
    12                                 Nos. 08-1351 & 06-3901
    sent. The bargained-for exchange between the parties
    provided that the Foundation would forego its right to
    separately license the patent in exchange for receiving a
    share of the profits from Xenon’s commercialization of
    the technology—either directly or via a sublicense to a
    third party. Xenon received a significant benefit from
    the agreement—the exclusive right to exploit the tech-
    nology protected by the joint patent application. Xenon
    cannot avoid paying royalties or sublicense fees to the
    Foundation simply by labeling the Novartis transaction
    a “license” rather than a “sublicense.”
    Accordingly, the terms of the Exclusive Licensing
    Agreement, not 
    35 U.S.C. § 262
    , govern the parties’ rights
    and responsibilities here. Under that agreement Xenon
    held an exclusive license to develop the SCD discovery
    for commercial purposes and a corresponding obligation
    to share proceeds with the Foundation. The agreement
    gives Xenon three options: (1) commercialize the technol-
    ogy directly and pay royalties to the Foundation;
    (2) sublicense the technology to a third party and pay a
    percentage of the sublicense fees to the Foundation; or
    (3) assign its exclusive licensing rights to a third party
    with the prior consent of the Foundation.
    Xenon suggests in the alternative that it never actually
    gave Novartis a license to the Foundation’s interest in the
    jointly patented technology. The district court properly
    rejected this argument. The Xenon-Novartis agreement
    provides that Xenon grants to Novartis an exclusive
    license to all Xenon technology in the field of human
    and animal healthcare. Xenon technology includes “Xe-
    Nos. 08-1351 & 06-3901                                    13
    non’s interest in all Patent Rights in the Field, as specifi-
    cally described in Schedule B,” and Schedule B promi-
    nently lists the joint patent application owned by Xenon
    and the Foundation—first out of four listed patents. Xenon
    argues unpersuasively that the phrase “patent rights” does
    not include rights it obtained through the Exclusive
    License Agreement. In the warranty clause of the Xenon-
    Novartis agreement, Xenon represents that “it is the
    owner or licensee of all rights, title and interest in and to
    the Xenon Patent Rights.” (Emphasis added.) Ac-
    cordingly, Xenon granted Novartis any interest it held
    in the joint patent application by specifically including it
    in Schedule B. Put another way, Xenon effectively
    sublicensed its exclusive license rights in the jointly
    patented technology. The district court correctly con-
    cluded that the Xenon-Novartis agreement is subject to
    the terms of the Exclusive License Agreement governing
    sublicenses.
    2. Sublicense Fees
    After concluding that Xenon granted Novartis a
    sublicense in the jointly patented technology, the district
    court held that Xenon violated the terms of the Exclusive
    License Agreement by failing to pay the Foundation a
    share of the sublicense fees. Xenon argues that it is not
    obligated to make payments to the Foundation until
    products are actually brought to market and sold as a
    result of the sublicense. Because no products have yet
    been sold, Xenon claims it does not owe the Foundation
    anything. Again, we disagree. The Exclusive License
    14                                    Nos. 08-1351 & 06-3901
    Agreement requires Xenon to pay the Foundation license
    fees, milestones, and royalty payments as soon as they
    are received.4
    Section 4 of the Exclusive License Agreement, titled
    “Consideration,” lays out the payment details and sched-
    ule. Subsection (B)(i) of that section states: “For all Prod-
    ucts sold directly by Xenon, Xenon shall pay to [the Founda-
    tion] . . . a royalty calculated as a percentage of the Selling
    Price of Products . . . .” (Emphasis added.) It goes on to
    specify that royalties are earned on either the date the
    product is actually sold, the date an invoice is sent, or
    the date the product is transferred to a third party for
    promotional reasons—whichever comes first. The next
    subsection—the provision most relevant to this dis-
    pute—states:
    For all Products sold by Xenon sublicensees, Xenon
    shall pay to [the Foundation] a percentage of any
    license fees, milestones, and royalty payments
    received by Xenon as consideration for the sublicense
    granted to such sublicensees under Section 2B. The
    percentage shall remain fixed at a rate of ten percent
    (10%) for years one (1) and two (2) of this Agreement
    and seven and one-half percent (7.5%) thereafter
    until this Agreement is terminated.
    Because both subsections begin with the phrase “[f]or all
    Products sold” (emphasis added), Xenon argues that it
    4
    Technically, the contract stipulates that Xenon must pay the
    Foundation on a quarterly basis, as specified in Section 4(E)(i)
    of the Exclusive License Agreement.
    Nos. 08-1351 & 06-3901                                    15
    does not owe the Foundation any payments for the
    Novartis sublicense until products are actually brought
    to market and sold.
    We agree with the district court that Section 4, read as a
    whole, requires payment of the Foundation’s share of
    the sublicense fee independent of any actual sales of
    products. The apparent point of the prefatory phrase “[f]or
    all Products sold” in each of the two subsections
    governing payment is to distinguish between payments
    required when Xenon commercialized the technology
    itself and payments required when Xenon issued a
    sublicense to a third party to do so. In the former circum-
    stance, the payment due the Foundation is a royalty
    based on products sold; in the latter circumstance, the
    payment due the Foundation is a specified percentage
    of the sublicense fee Xenon receives, plus “milestones” and
    royalties. Because the Novartis transaction falls under
    the second subsection, payment is due on receipt of a
    sublicense fee, not on the occurrence of product sales.
    This reading of the payment provision is the most
    plausible for several reasons. Although both subsections
    use the same introductory phrase, the first subsection
    also says that payment is due upon actual product sale
    while the second subsection—governing sublicenses—does
    not include similar language. Instead, the second sub-
    section states that Xenon owes the Foundation a
    percentage of any license fees and “milestones,” in addi-
    tion to royalty payments, stemming from any sub-
    license. As the district court noted, sublicense fees and
    milestone payments are not contingent upon a sale; they
    16                                     Nos. 08-1351 & 06-3901
    are paid immediately or on an ongoing basis by a
    licensee or sublicensee in exchange for the right to make
    sales of products developed in the future. Finally, the
    parties agree that it generally takes about 15 years to
    bring a drug product to market. Yet the Exclusive
    License Agreement specifies that Xenon must pay the
    Foundation 10% of any license fees, milestones, and
    royalty payments received during the first two years of
    the agreement and 7.5% thereafter. This provision would
    make little sense if no payment was required on
    a sublicense until a product was brought to market.
    Accordingly, the district court properly concluded that
    Xenon breached the Exclusive Licensing Agreement by
    failing to pay the Foundation its share of the fee from
    the Novartis transaction.5
    3. Damages
    The district court entered summary judgment on liabil-
    ity; damages were tried to a jury. Xenon’s agreement
    5
    After concluding that Xenon breached the Exclusive License
    Agreement, the district court dismissed the Foundation’s
    claim for breach of the implied duty of good faith as moot. The
    Foundation claims this was error. It was not. Under Wisconsin
    law a duty of good faith is implied in every contract. See
    Market Street Assocs. Ltd. P’ship v. Frey, 
    941 F.2d 588
    , 592 (7th
    Cir. 1991) (applying Wisconsin law). But because Xenon is liable
    for breach of the license agreement’s express terms, there is
    no reason to resort to—or separate factual basis to support—a
    claim for breach of the implied duty of good faith.
    Nos. 08-1351 & 06-3901                                         17
    with Novartis purported to grant a license to: (1) the joint
    patent agreement; (2) the PPA compounds; (3) several
    other patent applications; and (4) Xenon’s “know-how.”
    Novartis paid Xenon $4 million in cash and another
    $11 million in stock as part of a separate Stock Purchase
    Agreement signed the same day. The question for the
    jury was how much of this fee was payment for the joint-
    patent-agreement sublicense and the PPA compounds
    as opposed to the other pieces of the package.6 As we
    have noted, the Exclusive License Agreement stipulated
    that the Foundation should receive 7.5% of “any license
    fees, milestones, and royalty payments received by
    Xenon as consideration for the sublicense.” (Emphasis
    added.) In a special verdict, the jury awarded nothing
    for the sale of the PPA compounds and $1 million for the
    sublicense—just under 7.5% of the $15 million in cash
    and equity Xenon received from Novartis.
    Xenon moved posttrial for remittitur, which the
    district court granted. The judge held that “the jury had
    sufficient evidence to award plaintiff 7.5% of the full
    6
    While the district court concluded that Xenon owned the
    PPA compounds, it also held that the PPA compounds fell
    under the terms of the Exclusive License Agreement and that
    Xenon owed the Foundation fees for these compounds as
    well. We need not address the apparent incongruity in these
    conclusions; the jury made no award for the portion of the
    sublicense fee that included the PPA compounds. Moreover, as
    we explain, infra pp. 24-28, we are reversing the district court’s
    determination that the Foundation had no ownership interest
    in the compounds.
    18                                   Nos. 08-1351 & 06-3901
    $4,000,000 that Novartis paid in cash for defendant’s
    intellectual property.” But the judge concluded there
    was insufficient evidence to support inclusion of a per-
    centage of the $11 million in stock, which the evidence
    suggested was part of a separately negotiated agreement.
    The district court offered the Foundation a remittitur
    of $300,000—7.5% of the $4 million cash fee—which the
    Foundation accepted.
    On appeal Xenon argues that the Foundation did not
    provide sufficient evidence of damages to justify even a
    $300,000 damages award. We review sufficiency-of-the-
    evidence challenges de novo, viewing the evidence in
    the light most favorable to the prevailing party and
    drawing all inferences in its favor. Lopez v. City of Chicago,
    
    464 F.3d 711
    , 718 (7th Cir. 2006). Under Wisconsin law a
    plaintiff must present enough evidence to provide a
    reasonable basis for calculating damages; the evidence
    will be sufficient if it enables the jury to make a fair
    and reasonable approximation of damages. See Olympia
    Hotels Corp. v. Johnson Wax Dev. Corp., 
    908 F.2d 1363
    , 1372
    (7th Cir. 1990); Brogan v. Indus. Cas. Ins. Co., 
    392 N.W.2d 439
    , 444 (Wis. Ct. App. 1986).
    Under this lenient standard, the evidence is easily
    sufficient to sustain the damages award. The Foundation
    argued to the jury that the joint patent application was
    the only item in the Xenon-Novartis package with any
    real value, and thus the price Novartis paid reflected its
    fair market value. The Foundation relied on a sales-
    pitch letter Xenon sent to Novartis offering to sell the
    technology covered by the joint patent application; the
    Nos. 08-1351 & 06-3901                                    19
    letter made no mention of the PPA compounds or any
    other patented technology. The Foundation also noted
    that the joint patent application is listed first in the
    Novartis agreement, arguably demonstrating priority
    over the other listed patent applications. Moreover, the
    Foundation noted that Xenon transferred only about
    100 grams of the PPA compounds to Novartis—“left over”
    material that was so insignificant that Xenon did not
    price it or invoice it. Finally, the Foundation suggested
    that Xenon’s “know-how” was valueless because the
    phrase was defined in such a way as to include
    nothing beyond what was already covered under “Xenon
    Patent Rights.” Viewed in the light most favorable to the
    Foundation, this evidence was sufficient to sustain the
    damages award.
    Xenon complains that the Foundation did not ade-
    quately establish the precise market value of the sub-
    license for the joint patent application as compared to the
    other parts of the package. But Wisconsin law provides
    that a contracting party that causes an uncertainty of proof
    cannot demand a more precise measure of damages. See
    Novo Indus. Corp. v. Nissen, 
    140 N.W.2d 280
    , 285 (Wis. 1966).
    Xenon had a duty under the Exclusive Licensing Agree-
    ment to make an accounting to the Foundation on a
    quarterly basis, to disclose any payments received, and
    to explain how any amounts owed to the Foundation
    had been calculated. It did not do so. Under these cir-
    cumstances the Foundation was not required to estab-
    lish a more specific measure of damages.
    Xenon also argues that proving damages in this case
    required the use of expert testimony, citing a number of
    20                                  Nos. 08-1351 & 06-3901
    Wisconsin cases holding that expert testimony is
    required in complex or technical cases where the issue is
    outside the common knowledge of a jury. See, e.g., Weiss
    v. United Fire & Cas. Co., 
    541 N.W.2d 753
    , 757 (Wis. 1995)
    (“The court has long recognized that certain kinds of
    evidence are difficult for jurors to evaluate without the
    benefit of expert testimony.”). Here, although the inter-
    locking contracts were obviously technical and complex,
    the issue of damages was not beyond a lay juror’s under-
    standing. The Foundation was entitled to prove the
    value of the sublicense essentially by a process of elimina-
    tion—by showing that the other items in the Xenon-
    Novartis transaction had little or no value. This method
    of proving damages dispensed with any need for expert
    testimony regarding the market value of the joint
    patent application.
    4.   The Foundation’s Right to Terminate the Exclusive
    License Agreement
    In addition to damages, the Foundation also asked for
    a declaration that it had a right to terminate the
    Exclusive License Agreement based on Xenon’s breach.
    The district court granted summary judgment for the
    Foundation on this claim, and on May 17, 2006, the
    Foundation sent Xenon a letter terminating the Exclusive
    License Agreement. Xenon responded with two
    motions, one for reconsideration of the district court’s
    decision and the other for a stay of execution of the judg-
    ment pending disposition of Xenon’s motion for recon-
    sideration. The district court granted Xenon’s motion
    Nos. 08-1351 & 06-3901                                 21
    to stay enforcement of the judgment, holding that the
    Foundation’s purported termination of the Exclusive
    License Agreement was void because the Foundation had
    not given Xenon notice and 90 days to cure its breach, as
    the agreement required. The court further held that once
    the Foundation filed this lawsuit, its right to terminate
    the license agreement depended on a finding of breach
    by the court. The judge concluded as follows: “[A]ny
    attempted termination of the agreement that has already
    occurred is suspended until the court has ruled on the
    post-trial motions and plaintiff may not take renewed
    action to terminate the agreement until that time.” A
    month later, the district court granted Xenon’s motion
    for reconsideration, agreeing that the Foundation had not
    properly moved for summary judgment on this claim.
    However, the judge also said that if the Foundation
    wanted to terminate the Exclusive License Agreement, it
    could now do so—because Xenon had been found in
    breach—but that the Foundation was first required under
    the terms of the agreement to give Xenon notice and
    90 days to cure.
    On appeal the Foundation challenges the district
    court’s conclusion that its right to terminate the agree-
    ment did not arise until the court found Xenon in breach
    of the agreement. The Foundation maintains that its
    right to terminate was triggered by Xenon’s breach and
    was not contingent upon the court’s finding of breach. The
    Foundation also argues that it properly terminated the
    agreement. We agree on both counts.
    Section 7 of the Exclusive License Agreement governs
    the Foundation’s right to terminate:
    22                                     Nos. 08-1351 & 06-3901
    If Xenon at any time defaults in the timely payment of
    any monies due . . . or commits any breach of any
    other covenant herein contained, and Xenon fails to
    remedy any such breach or default within ninety (90)
    days after written notice thereof by [the Founda-
    tion,] . . . [the Foundation] may, at its option, terminate
    this Agreement by giving notice of termination to
    Xenon.
    In March 2005 the Foundation sent Xenon written notice
    that it considered the Xenon-Novartis transaction to be a
    sublicense of the joint patent application and that
    Xenon owed the Foundation sublicense fees. The
    relevant portion of the letter states:
    Our analysis has led us to conclude that the Novartis
    agreement is, in fact, a sub-license of rights granted
    by [the Foundation] to Xenon and we also require
    that Xenon remit . . . payment of any amounts owed to
    [the Foundation] under the Agreement. In the event
    that Xenon contends that no amounts are owed to [the
    Foundation] or that the Novartis agreement is not a
    sublicense as contemplated by the Agreement, Xenon
    must immediately provide . . . a detailed written
    explanation as to why such amounts are not owed or
    why the Novartis agreement is not a sublicense . . . .
    This letter plainly gave Xenon notice that the Foundation
    considered it to be in breach of its payment obligations
    under the Exclusive License Agreement. Notably, Xenon
    does not disagree. Instead, Xenon argues that the Founda-
    tion did not provide 90 days to cure the breach because
    the Foundation filed suit a month after sending Xenon
    Nos. 08-1351 & 06-3901                                     23
    this letter. The March 2005 notice, Xenon says, was there-
    fore ineffective under the termination provision of the
    Exclusive License Agreement.
    We disagree. A contractual obligation to provide notice
    and an opportunity to cure a default prior to terminating
    a contract does not necessarily affect the aggrieved party’s
    right to sue for breach. See Ameritech Info. Sys., Inc. v. Bar
    Code Res., Inc., 
    331 F.3d 571
    , 573-74 (7th Cir. 2003). Here,
    nothing in the Exclusive License Agreement prevented
    the Foundation from suing for breach within the 90-day
    cure period, 
    id. at 574
    , nor was the Foundation’s right
    to terminate somehow suspended by the filing of this
    lawsuit. Having filed the suit, the Foundation’s right to
    terminate did not become contingent upon the court
    finding Xenon in breach. A contracting party’s right to
    terminate arises under the terms of the contract and
    need not await a formal declaration of the contracting
    parties’ rights.
    Here, the district court issued a stay of the execution of
    its summary-judgment ruling pending disposition of
    Xenon’s posttrial motions. A stay, unlike an injunction,
    operates only on the judicial proceeding itself and does
    not otherwise prohibit the parties from acting. See Nken
    v. Holder, 
    129 S. Ct. 1749
    , 1757-58 (2009) (“An injunction
    and a stay have typically been understood to serve dif-
    ferent purposes. The former is a means by which a court
    tells someone what to do or what not to do. . . . By contrast,
    instead of directing the conduct of a particular actor, a
    stay operates upon the judicial proceeding itself.”). Some
    of the court’s language in the stay order is suggestive of
    24                                  Nos. 08-1351 & 06-3901
    an injunction: “[A]ny attempted termination of the agree-
    ment that has already occurred is suspended until the
    court has ruled on the post-trial motions and plaintiff
    may not take renewed action to terminate the agreement
    until that time.” But if this was meant to be an injunction,
    it was an improper one. As a procedural matter, injunc-
    tions must comply with the requirements of Rule 65(d) of
    the Federal Rules of Civil Procedure; a court issuing
    an injunction must, among other things, give advance
    notice to the adverse party, hold a hearing on the matter,
    explain why the injury that would occur without the
    injunction is irreparable, and specify the scope of the
    injunction in reasonable detail. The district court’s stay
    order did not comply with these requirements.
    Accordingly, the district court erroneously concluded
    that the Foundation’s right to terminate the agreement
    was contingent upon the court’s finding that Xenon had
    breached the Exclusive License Agreement. The Founda-
    tion was entitled to terminate the agreement based on
    Xenon’s breach, and it properly did so under the agree-
    ment’s termination provision. The Foundation’s
    March 2005 letter was sufficient to give notice to Xenon
    that the Foundation considered it in breach. More than
    90 days elapsed between the time of this notice and the
    Foundation’s letter—on May 17, 2006—terminating the
    license agreement. Nothing more was required.
    B. PPA Compounds
    We move now to the second set of issues on appeal
    concerning the ownership rights to the PPA compounds.
    Nos. 08-1351 & 06-3901                                     25
    The Foundation brought several claims pertaining to its
    interests in the PPA compounds: It sued for a declaratory
    judgment that Gray-Keller’s assignment to Xenon of his
    interest in the compounds was void; it sought to quiet
    title in the PPA compounds; and it sued for conversion
    of its property rights. The parties filed cross-motions for
    summary judgment on each of these claims, and the
    district court entered judgment for Xenon on all three
    claims. On appeal the Foundation reasserts its entitle-
    ment to an ownership interest in the PPA compounds.
    A brief recap of the relevant facts is in order: Xenon, with
    the help of Discovery Partners, used the jointly patented
    assay to screen thousands of compounds for therapeutic
    potential. Xenon and Discovery Partners identified a set
    of 20 “PPA compounds” with the potential to lower SCD
    levels in the human body, and Xenon sent these com-
    pounds to Gray-Keller for confirmatory screening. Gray-
    Keller confirmed the cholesterol-inhibiting potential of
    the PPA compounds and in July 2003 purported to
    assign his rights to Xenon pursuant to the terms of his
    consulting agreement.
    The Foundation contends that the interlocking network
    of contracts among the parties gives it ownership of Gray-
    Keller’s interest in the PPA compounds, and therefore
    Gray-Keller’s assignment is void.7 We agree. Under the
    7
    Xenon argues that the Foundation is barred from bringing a
    claim for ownership of the PPA compounds by the Settle-
    ment and Release Agreement signed by Xenon and the Univer-
    (continued...)
    26                                   Nos. 08-1351 & 06-3901
    Sponsor Option Agreement, all University researchers
    working on the Xenon-funded research program agreed
    to assign to the Foundation their rights to any inventions
    that they “conceived of or reduced to practice . . .
    whether solely or jointly with others.” Each University
    researcher, including Gray-Keller, signed an individual
    Memorandum Agreement to that effect, and copies were
    attached to and incorporated as part of the Sponsor
    Option Agreement. The scope of the joint research
    program was defined by three separate research agree-
    ments—Research Agreements 1, 2, and 3.
    The Foundation maintains that Gray-Keller’s work on
    the PPA compounds fell within the scope of Research
    Agreement 2, and therefore Gray-Keller was required to
    assign his interest in the compounds to the Foundation.
    Research Agreement 2 generally covers research to
    identify compounds that will influence SCD levels in the
    human body for therapeutic effect on cholesterol levels.
    While the scientific language and acronyms keep the
    contract from being readily understandable to a
    layperson, the scope of the research program is clear
    enough. First, Exhibit A to Research Agreement 2 is titled
    “Stearoyl CoA Desaturase (SCD) as a Target for
    7
    (...continued)
    sity in 2003. We need not spend much time on this argument.
    As we have explained, supra n.1, the 2003 settlement per-
    tained to a funding dispute between the University and Xenon;
    it had nothing to do with who owns the intellectual-property
    rights to the discoveries resulting from the jointly sponsored
    research.
    Nos. 08-1351 & 06-3901                                  27
    Elevation of HDL.” It states that its overall goal is to
    “evaluate SCD as a target for the development of drugs
    that would increase the levels of HDL in plasma and
    decrease triglycerides (which should have a therapeutic
    impact on cardiovascular disease).” It then lists a handful
    of more specific goals, such as to “[s]creen and rank order
    substrates/inhibitors of SCD1 activity for impact on SCD1
    transcription in vitro” and to “[e]valuate lead sub-
    strates/inhibitors from in vitro screen for their effect on
    SCD1 transcription, SCD1 enzyme activity and HDL
    metabolism in vivo.”
    Gray-Keller’s work identifying and confirming the
    therapeutic potential of the PPA compounds derived from
    the SCD enzyme was expressly contemplated by
    Research Agreement 2, which broadly covered research
    “to validate SCD as a target for screening novel com-
    pounds that may elevate HDL levels in vivo.” Gray-Keller
    performed his research on this project at the University
    using University resources and was required under his
    Memorandum Agreement to assign his interest in any
    discoveries to the Foundation. The fact that his work was
    conducted partly under Xenon’s sponsorship and at its
    behest is not dispositive. Under the Sponsor Option
    Agreement and each of the individual agreements
    attached to it, the Foundation was entitled to ownership
    of any discoveries “conceived of or reduced to practice”
    by the researchers under the joint research program;
    Xenon was entitled to an exclusive license to com-
    mercialize the discoveries. Accordingly, the district court
    erred in granting summary judgment to Xenon on the
    claims pertaining to the Foundation’s ownership interest
    28                                   Nos. 08-1351 & 06-3901
    in the PPA compounds. Under the Sponsor Option Agree-
    ment, the Memorandum Agreement, and Research Agree-
    ment 2, the Foundation was entitled to a declaration of
    its ownership interest in the PPA compounds.8
    III. Conclusion
    For the foregoing reasons, we A FFIRM the judgment for
    the Foundation on its claim that Xenon breached the
    Exclusive License Agreement, as well as the district court’s
    order entering judgment on the remittitur in the amount
    of $300,000. We R EVERSE the district court’s recon-
    sideration order regarding the Foundation’s right to
    terminate the Exclusive License Agreement; under the
    terms of the agreement’s termination provision, the
    Foundation was entitled to and properly terminated the
    agreement. Finally, we R EVERSE the judgment in favor
    of Xenon on the Foundation’s claims to quiet title and
    for declaratory judgment that Gray-Keller’s purported
    assignment of his interest in the PPA compounds to
    Xenon is void. On these claims, we R EMAND with instruc-
    tions to enter judgment in favor of the Foundation.
    8
    Our holding in this regard makes it unnecessary to consider
    the Foundation’s alternative argument that it had a right to
    an ownership interest in the PPA compounds under the Bayh-
    Dole Act.
