    Before PROST, Chief Judge, CLEVENGER and MOORE,
    Circuit Judges.
    Opinion for the court filed by Chief Judge PROST.
    Dissenting opinion filed by Circuit Judge CLEVENGER.
    PROST, Chief Judge.
    Plaintiff-appellant Mr. Dennis DeVona sued Defend-
    ant-appellee Dr. Steven Zeitels for breach of an alleged
    partnership agreement and breach of fiduciary duty. At
    trial, the jury returned a verdict in Mr. DeVona’s favor. Af-
    ter reviewing the evidence presented at trial, however, the
    U.S. District Court for the District of Massachusetts
    granted Dr. Zeitels’s motion for judgment as a matter of
    law (“JMOL”). The district court determined that no rea-
    sonable jury could have found that a continuing partner-
    ship existed after May 1999. Mr. DeVona appeals. We
    affirm.
    BACKGROUND
    I
    Mr. DeVona is a craftsman and art appraiser. Dr.
    Zeitels is a throat surgeon who specializes in treating
    throat cancers.
    In 1994, Dr. Zeitels informed Mr. DeVona that he was
    designing a new glottiscope, which is a medical instrument
    for laryngeal surgery. He offered to let Mr. DeVona “quar-
    terback” the project since Dr. Zeitels did not have the time
    or experience to get involved with manufacturing the in-
    strument. J.A. 236–37. Mr. DeVona was not interested.
    In 1997, however, Mr. DeVona and Dr. Zeitels resumed
    their discussions. The two met at Dr. Zeitels’s house in
    DEVONA v. ZEITELS                                          3
    Boston, where Dr. Zeitels showed Mr. DeVona various
    medical instruments and demonstrated the progress he
    had made in the glottiscope design.
    At a second meeting, the parties agreed to work with
    one another. The nature of their small-scale undertaking
    was clear. After the design was finalized, they would de-
    velop a prototype. Subsequently, they would have the
    product manufactured, prove its marketability, and sell the
    company and/or the intellectual property to a larger-scale
    producer as soon as possible. J.A. 413–14; J.A. 245. Ac-
    cording to Mr. DeVona, the purpose of this joint business
    endeavor was “to develop a surgical instrument or surgical
    instruments” and “sell the intellectual property to the high-
    est bidder as soon as [they] could.” J.A. 245. Dr. Zeitels
    “would put up the money,” Mr. DeVona “would put up the
    energy and work it would take,” and they would “try and
    knock it out in 12 months.” 
    Id. Dr. Zeitels
    and Mr. DeVona
    agreed to split the profits 60%–40% respectively. 
    Id. In 1998,
    Dr. Zeitels and Mr. DeVona moved forward
    with their new undertaking. They opened a joint bank ac-
    count, which Dr. Zeitels funded. By early 1999, Dr. Zeitels
    and Mr. DeVona had developed a prototype to offer to a
    medical device manufacturer for production.
    In April 1999, Dr. Zeitels and Mr. DeVona met with a
    manufacturing company, ACT Medical, in Boston. At the
    meeting, the parties evaluated whether it was feasible to
    hire ACT Medical as a subcontractor to manufacture the
    glottiscope. After ACT Medical quoted a price of $600,000
    to make the first hundred devices, Dr. Zeitels and Mr.
    DeVona concluded that a subcontractor “was too expensive
    to go with.” J.A. 331.
    II
    At that point, Dr. Zeitels and Mr. DeVona decided to
    “switch gears.” J.A. 414 (DeVona Testimony). According
    to Mr. DeVona, “We thought we could sell the company
    4                                          DEVONA v. ZEITELS
    early. And when we went to ACT Medical a month earlier,
    we realized it was a no-go just to have it made and just sell
    the company.” 
    Id. As a
    result, the parties completely restructured their
    relationship in the spring of 1999. About a week after the
    ACT Medical meeting, the company Endocraft was formed.
    Dr. Zeitels created the company and put up the money to
    fund it. Dr. Zeitels owned Endocraft. J.A. 1187 (Endocraft
    Action Form). The parties closed their old joint bank ac-
    count and opened a new Endocraft account. In an applica-
    tion for a $20,000 credit card for the new company, Dr.
    Zeitels was listed as the 100% owner of Endocraft. Mr.
    DeVona’s ownership stake was listed as 0%.
    Dr. Zeitels also presented Mr. DeVona with an “Inde-
    pendent Sales Representative Agreement” (“ISRA”).
    J.A. 338 (DeVona Testimony); J.A. 1192–98 (ISRA). Per
    that agreement, Mr. DeVona was to become a “Sales Rep-
    resentative to sell the products of [Endocraft],” employed
    on an “at will” basis. J.A. 1192 (¶¶ 1, 5). For his work, Mr.
    DeVona was to receive a commission of 40% of net sales
    after deductions for research and development costs.
    J.A. 1193 (¶ 6(a)). The fully-integrated agreement stated:
    “Nothing contained in this Agreement shall be construed
    to constitute the Sales Representative as a partner, em-
    ployee, or agent of [Endocraft].” J.A. 1196 (¶ 12). Mr.
    DeVona expressed some concerns about the agreement but
    ultimately signed it. J.A. 1197.
    As of May 1999, Endocraft was the “vehicle for [their]
    relationship.” J.A. 494 (DeVona Testimony). Similarly,
    Mr. DeVona testified that the ISRA was “a vehicle for our
    overall vision and plan as partners.” J.A. 553. The ISRA
    explicitly disclaimed that Mr. DeVona had any stake in En-
    docraft.
    Eventually, the relationship between the parties be-
    came strained. J.A. 536; J.A. 356. In 2011, Dr. Zeitels
    ended Mr. DeVona’s employment and sold Endocraft.
    DEVONA v. ZEITELS                                          5
    III
    On April 17, 2013, Mr. DeVona filed a complaint in the
    District of Massachusetts. The complaint raised a correc-
    tion of inventorship claim under 35 U.S.C. § 256, as well as
    an unjust enrichment claim based on Dr. Zeitels’s alleged
    misuse of intellectual property belonging to Mr. DeVona.
    In addition, the complaint pled three partnership-related
    claims: (1) violation of the Rhode Island Uniform Partner-
    ship Act; (2) breach of fiduciary duty; and (3) breach of a
    partnership agreement. For each partnership claim, Mr.
    DeVona’s allegations assumed that the parties had been in
    a continuous partnership from 1997 through 2011. Mr.
    DeVona alleged that he was not an Endocraft employee but
    instead Dr. Zeitels’s partner. Thus, regardless of his com-
    mission of 40% of Endocraft’s net sales, Mr. DeVona
    averred that he was entitled to a partnership share of 40%
    of the profits from selling Endocraft.
    The parties went to trial on the patent inventorship
    claim and partnership claims. The jury found against Mr.
    DeVona on patent inventorship, rejecting his theory that
    he meaningfully contributed to the glottiscope design em-
    bodied by U.S. Patent No. 6,955,645. Thus, Dr. Zeitels re-
    mains the only inventor listed on the patent. However, the
    jury found in Mr. DeVona’s favor on the partnership
    claims. For breach of fiduciary duty, the jury awarded
    $395,907. For breach of the partnership agreement, the
    jury awarded Mr. DeVona $352,007.
    Both parties filed post-trial motions. Reviewing the
    record evidence, the district court granted Dr. Zeitels’s mo-
    tion for JMOL. The district court concluded that while the
    jury may have had a basis in the record to find that the
    parties initially entered into a partnership in 1997 for the
    purpose of developing a product and quickly selling the
    business to a third-party producer, “any such partnership
    dissolved under Rhode Island law once [Mr.] DeVona and
    [Dr.] Zeitels abandoned that initial undertaking after the
    6                                          DEVONA v. ZEITELS
    meeting with ACT Medical to embark instead on a new tact
    of actually manufacturing instruments and selling them on
    a long term basis.” J.A. 7. The district court also condi-
    tionally granted Dr. Zeitels’s new trial motion, concluding
    that the jury’s verdict of a partnership “after April or May
    1999 is sufficiently contrary to the great weight of the trial
    evidence.” J.A. 11 (discussing Fed. R. Civ. P. 50(c)(1) & 59).
    Mr. DeVona appealed the JMOL decision as to the
    partnership claims. We have jurisdiction under 28 U.S.C.
    § 1295(a)(1).
    DISCUSSION
    On appeal, Mr. DeVona mounts three challenges.
    First, he contends that the district court erred by conclud-
    ing that there was insufficient evidence of a partnership
    after 1999. Second, he argues that the district court abused
    its discretion by excluding an email related to his claims
    that a partnership existed through 2011. Third, he avers
    that the district court erred by conditionally granting a
    new trial.
    I
    We apply the law of the regional circuit when reviewing
    district court rulings on post-judgment motions. Verizon
    Servs. Corp. v. Cox Fibernet Va., Inc., 
    602 F.3d 1325
    , 1331
    (Fed. Cir. 2010). Under First Circuit law, the grant of a
    motion for JMOL is reviewed de novo. Malone v. Lockheed
    Martin Corp., 
    610 F.3d 16
    , 19–20 (1st Cir. 2010).
    JMOL is appropriate when “the facts and inferences”
    from the evidence introduced at trial “point so strongly and
    overwhelmingly in favor of the movant that a reasonable
    jury could not have returned the verdict.” Mercado-Berrios
    v. Cancel-Alegria, 
    611 F.3d 18
    , 22 (1st Cir. 2010) (quoting
    Mass. Eye and Ear Infirmary v. QLT Phototherapeutics,
    Inc., 
    552 F.3d 47
    , 57 (1st Cir. 2009)). A court considers “all
    of the evidence and reasonable inferences drawn from the
    evidence . . . in the light most favorable to the non-moving
    DEVONA v. ZEITELS                                           7
    party.” Cham v. Station Operators, Inc., 
    685 F.3d 87
    , 93
    (1st Cir. 2012) (quoting 
    Malone, 610 F.3d at 20
    ). However,
    the non-movant “is not entitled to inferences based on spec-
    ulation and conjecture.” 
    Id. (quoting Vázquez–Valentín
    v.

    , 
    126 S. Ct. 1329
    , 
    164 L. Ed. 2d 43
    (2006)). Rather, “to support a jury finding,” the evidence
    presented must “make the existence of the fact to be in-
    ferred more probable than its nonexistence.” Irvine v. Mu-
    rad Skin Research Labs., Inc., 
    194 F.3d 313
    , 317 (1st Cir.
    1999) (quoting Alvarez–Fonseca v. Pepsi Cola Bottling Co.
    of P.R., 
    152 F.3d 17
    , 24 (1st Cir. 1998)).
    II
    Under the Rhode Island Uniform Partnership Act, a
    “partnership” is “an association of two (2) or more persons
    to carry on as co-owners a business for profit.” R.I. Gen.
    Laws § 7–12–17(a). The statute enumerates certain rules
    for determining the existence of a partnership. See 
    id. § 7–
    12–18. Most relevantly here, the statute provides that
    commonly owned property “does not of itself establish a
    partnership,” the “sharing of gross returns does not of itself
    establish a partnership,” and “receipt by a person of a share
    of the profits of a business is prima facie evidence that he
    or she is a partner in the business, but no such inference is
    drawn if profits were received in payment . . . [a]s wages of
    an employee.” 
    Id. § 7–12–18(2),
    (3), (4)(ii).
    Given the “dearth” of cases interpreting this statute,
    however, “the Rhode Island legislature has counseled the
    courts to look to the interpretations which other states
    have given the Uniform Partnership Act (UPA), upon
    which section 7–12–18 is based.” Southex Exhibitions, Inc.
    v. R.I. Builders Ass’n., 
    279 F.3d 94
    , 98 n.2 (1st Cir. 2002).
    In addition, courts “frequently consider indicia of partner-
    ship formation not prescribed in the UPA.” 
    Id. at 101.
    The
    existence of a partnership “must be assessed under a ‘total-
    ity-of-the-circumstances’ test.” 
    Id. at 100.
    8                                          DEVONA v. ZEITELS
    In keeping with these principles, the jury was in-
    structed to consider the following indicia to determine if a
    partnership existed:
    1. whether the parties agreed to share in the prof-
    its of the business relationship,
    2. whether the parties shared any losses of the
    business relationship,
    3. the parties’ respective contributions to the busi-
    ness relationship, whether monetary, labor or
    otherwise,
    4. the parties’ control over bank accounts or other
    assets, and if a joint bank account exists,
    whether that account is for convenience only or
    whether the party placing funds in that account
    intended to make such funds jointly owned,
    5. whether the parties shared the management de-
    cisions of the business,
    6. whether the partnership conducted business in
    its own name,
    7. whether the business filed partnership tax re-
    turns, and
    8. how Mr. DeVona and Dr. Zeitels held themselves
    out to third parties.
    J.A. 1110 at ll. 2–17 (Jury Instructions). These factors are
    guideposts; no single indicia is conclusive. 
    Id. at ll.
    18–20.
    A
    Neither party challenges the district court’s conclusion
    that based on the criteria above, there is enough evidence
    for a reasonable jury to conclude that an initial partnership
    was formed verbally between Mr. DeVona and Dr. Zeitels
    in 1997. See Appellant’s Br. 43; Appellee Br. 32–33. In-
    stead, the parties dispute whether that partnership
    DEVONA v. ZEITELS                                           9
    dissolved in 1999. A partnership dissolves without viola-
    tion of the agreement by “the termination” of the “particu-
    lar undertaking specified in the agreement.” R.I. Gen.
    Laws § 7–12–42(1)(i). Otherwise, if the partnership is not
    tied to a particular undertaking, the partnership may be
    dissolved by the express will of a partner. 
    Id. § 7–12–
    42(1)(ii).
    There is no dispute that to the extent a partnership
    formed in 1997 between Mr. DeVona and Dr. Zeitels, it was
    for a particular undertaking. The parties’ dispute focuses
    only on the scope of that undertaking.
    In Mr. DeVona’s view, the district court characterized
    the particular undertaking too narrowly. The district court
    concluded a reasonable jury could find that Mr. DeVona
    and Dr. Zeitels formed “a partnership to create a company
    or a surgical device and to sell that device or company, or
    the intellectual property associated therewith, to the high-
    est bidder in the shortest amount of time possible.” J.A. 7.
    Based on the trial evidence, however, the court concluded
    that any partnership dissolved once Mr. DeVona and Dr.
    Zeitels abandoned that initial undertaking following the
    meeting with ACT Medical and started a new business “ac-
    tually manufacturing instruments and selling them on a
    long term basis.” 
    Id. Mr. DeVona
    contends the partners only ever had a sin-
    gle, consistent “shared goal” of eventually “selling a profit-
    able business.” Appellant’s Br. 6, 13. According to Mr.
    DeVona, the broad undertaking never terminated, and
    thus the partnership never dissolved.
    Mr. DeVona’s attempt to take a single aspect of their
    original plan—“selling the business”—and read out his
    own clear testimony about the timing and nature of the un-
    dertaking is unavailing. When testifying at trial about the
    initial terms of the partnership, Mr. DeVona testified:
    10                                         DEVONA v. ZEITELS
    Q. What was the nature of the work that the two
    of you agreed that you would do?
    A. It would be to develop a surgical instrument or
    surgical instruments, that we would sell the intel-
    lectual property to the highest bidder as soon as we
    could.
    J.A. 245. Mr. DeVona further testified that the partner-
    ship was to “build a company,” “build its assets,” and “sell
    it as soon as we could, hopefully, in a year, and . . . [the]
    partnership wouldn’t be over until we sold it and made the
    money.” J.A. 360; see also J.A. 413–14 (explaining plan to
    get business sold “as soon as possible”).
    As a fundamental part of that undertaking, Mr.
    DeVona and Dr. Zeitels planned to secure a medical device
    manufacturer to make the product, allowing them to sell
    the company on a fast timeline. J.A. 245; J.A. 329–31. Ac-
    cording to Mr. DeVona, he and Dr. Zeitels met with a med-
    ical device manufacturer, ACT Medical, but “we both
    learned that it was too expensive to go with a surgical in-
    strument company making [the product] as a subcontrac-
    tor.” J.A. 331. He explained that after “they quoted us
    about $600,000 to make the first hundred, we decided that
    we might have to make it ourselves.” 
    Id. Mr. DeVona
    testified that as a result of the meeting
    with ACT Medical, they “switched gears.” J.A. 414. Mr.
    DeVona then summarized the status of their business: “We
    decided to switch gears. We thought we could sell the com-
    pany early. And when we went to ACT Medical a month
    earlier, we realized it was a no-go just to have it made and
    just sell the company.” Id.; see also J.A. 332 (“Q. What hap-
    pened next after the meeting at ACT Medical? A. Well, we
    decided to make the instrument ourselves . . . .”).
    As the district court concluded, at best the evidence
    supports a finding that the parties formed a partnership
    for a “particular undertaking” in 1997, but that
    DEVONA v. ZEITELS                                         11
    undertaking terminated in 1999 when they switched gears
    to a much longer-term business of manufacturing the prod-
    uct.
    B
    Mr. DeVona next argues that if the original undertak-
    ing terminated in 1999, the partnership nonetheless con-
    tinued after Endocraft was formed until it was eventually
    sold in 2011. The district court concluded that based on the
    record evidence, no reasonable jury could find that a part-
    nership continued after Mr. DeVona and Dr. Zeitels de-
    cided to “switch gears” in 1999. J.A. 7. We agree.
    If a partnership for a “fixed term” or “particular under-
    taking” is “continued after the termination” of such “term
    or particular undertaking without any express agreement,
    the rights and duties of the partners remain the same as
    they were at the termination, insofar as is consistent with
    a partnership at will.” R.I. Gen. Laws § 7–12–34(a). “A
    continuation of the business by the partners . . . without
    any settlement or liquidation of the partnership affairs, is
    prima facie evidence of a continuation of the partnership.”
    
    Id. § 7–12–
    34(b).
    Mr. DeVona’s primary argument is that since he
    worked with Dr. Zeitels on a medical instrument after En-
    docraft formed in 1999, there was a “continuation of the
    business by the partners.” He portrays Endocraft as
    merely a sales arm carrying out the goals of a surviving
    “umbrella partnership.” Appellant’s Br. 38. This argu-
    ment fails for two reasons.
    First, there was no continuation of the original busi-
    ness. As discussed above, the business itself fundamen-
    tally changed in 1999 to a long-term undertaking involving
    the actual manufacture of the products. Endocraft was
    formed as the only vehicle for that new manufacturing-fo-
    cused business. Mr. DeVona became an employee. He
    signed an employment agreement with Endocraft. Thus,
    12                                         DEVONA v. ZEITELS
    while the parties continued to work together in general on
    a medical instrument, the undisputed record confirms that
    “the business” itself had changed. Accordingly, no reason-
    able jury could have concluded there was a continuation of
    the original business after 1999.
    Second, even if we were to accept that there was a “con-
    tinuation of the business” such that Mr. DeVona made a
    prima facie showing the partnership continued, R.I. Gen.
    Laws § 7–12 –34(b), this showing is rebutted by the glaring
    absence of any objective indicia of partnership after Endo-
    craft formed in 1999. Those indicia are discussed below. 1
    1
    With regard to the first two indicia, there is no evidence
    Mr. DeVona actually shared in the “profits” and “losses” of
    the medical device business. J.A. 1110 (Jury Instructions).
    Courts have noted that the UPA “has placed specific em-
    phasis on profit-sharing as a ‘particularly probative indi-
    cium of partnership formation, and some courts have even
    held that the absence of profit sharing compels a finding
    that no partnership existed.’” Acinapura v. Natalizia, No.
    PC 1999-2007, 
    2003 WL 22048717
    , at *5 (R.I. Super. July
    30, 2003) (quoting 
    Southex, 279 F.3d at 101
    ); see also
    1  There are few decisions analyzing when a “particu-
    lar undertaking is continued” under Section 7–12–34(a).
    Likewise, the parties cite no binding case law for determin-
    ing what constitutes “continuation of the business,” or how
    that prima facie showing of partnership may be rebutted
    by evidence confirming there is no “continuation of the
    partnership.” See R.I. Gen. Laws § 7–12–34(b). However,
    the parties’ arguments assume that the continued exist-
    ence of a partnership is measured by the same indicia that
    evidence its formation. In the absence of controlling case
    law to the contrary, we agree this is an appropriate tool for
    divining whether a partnership endures.
    DEVONA v. ZEITELS                                        13
    McAleer v. Smith, 
    57 F.3d 109
    , 115 (1st Cir. 1995) (holding
    no partnership existed between vessel’s owner and opera-
    tor because operator lacked any ownership interest in ves-
    sel, did not “share in the profits” from vessel operations,
    and had no control over vessel’s itinerary). “State law nor-
    mally presumes that partners share equally or at least pro-
    portionately in partnership losses.” 
    Southex, 279 F.3d at 99
    (citing R.I. Gen. Laws §§ 7–12–26(a), 7–12–29(1) & (2)).
    Mr. DeVona repeatedly conceded at trial that Endo-
    craft was the only “vehicle” of their purported larger busi-
    ness. See, e.g., J.A. 499. Yet there is no evidence in the
    record he received a profit disbursement from Endocraft.
    J.A. 500 (“Q. Did you or Dr. Zeitels ever receive any actual
    income from the partnership? A. . . . I never did.”). Re-
    markably, over the dozen years that Endocraft remained in
    existence, the record shows Mr. DeVona never discussed a
    profit disbursement with Dr. Zeitels—even after the com-
    pany became profitable in 2005. See J.A. 428–30; J.A. 499–
    500.
    Likewise, there is no evidence of record that Mr.
    DeVona shared in any of the actual losses of Endocraft, in-
    cluding when it was not profitable for the first few years.
    Mr. DeVona contends that he “guaranteed the debt of the
    company,” Appellant’s Br. 39, but the record does not sup-
    port this sweeping statement. The only record evidence
    that Mr. DeVona potentially served as a guarantor in any
    capacity was a single credit card he guaranteed with Dr.
    Zeitels for the company. J.A. 371–72, J.A. 1205. However,
    there is no evidence that when Endocraft was losing money
    in the early years, Mr. DeVona paid anything toward the
    credit card (or any other debt). Instead, Dr. Zeitels shoul-
    dered all the actual losses of Endocraft. See J.A. 429.
    Moreover, there is a complete lack of evidence that
    partnership profits/losses were ever tracked or recorded.
    As Mr. DeVona conceded, there were no books for the um-
    brella partnership. J.A. 499. There was no accounting
    14                                         DEVONA v. ZEITELS
    firm. 
    Id. There were
    no monthly reports. 
    Id. There were
    no annual reports. 
    Id. As Mr.
    DeVona put it, any financial
    reporting or accounting regarding the medical business
    “was all about Endocraft, LLC, the vehicle for our partner-
    ship.” 
    Id. Thus, there
    is no meaningful evidence of profit or loss
    sharing. The first two indicia therefore clearly cut against
    the existence of a partnership.
    2
    We turn next to financial and labor contributions. The
    record is plain that Dr. Zeitels was the sole source of finan-
    cial support for the business when Endocraft formed. See
    J.A. 428 (“Q. And [Endocraft] was his company? A. Sure.
    Q. He put the money into it, correct? A. Yes, he did.”);
    J.A. 429 (“Before there were any sales, he paid me out of
    Endocraft, which he put the money into.”).
    The record is equally clear that while Mr. DeVona con-
    tributed significant labor to the medical business operating
    as Endocraft, he did so as a paid employee. The ISRA he
    signed ensured that he was compensated with a commis-
    sion of 40% of profits from net sales. J.A. 1193 (¶ 6(a)).
    Mr. DeVona contends he was compensated outside the
    terms of the agreement until 2011. He infers that he was
    therefore being compensated as a partner. But as Mr.
    DeVona testified, whether officially labeled as a “salary,”
    “it was pay for work.” J.A. 429. His testimony on this point
    is clear and uncontradicted. The facts cannot support the
    inference that Mr. DeVona presses for here. The record ev-
    idence only supports the conclusion that he was being paid
    as an employee of Endocraft for his contributions, albeit at
    times outside the strict parameters set out in the ISRA.
    Indeed, beginning in 2002 and continuing after Endo-
    craft became profitable in 2005, Dr. Zeitels paid Mr.
    DeVona an annual salary. J.A. 349; J.A. 428–30; see also
    J.A. 430 (“Q. So we had advances before there were any
    DEVONA v. ZEITELS                                         15
    sales. Then you got paid when there were sales even before
    there was a profit?[;] A. Yes, out of Endocraft income.”). It
    is undisputed that over the course of Endocraft’s operation,
    Mr. DeVona received up to $850,000 in compensation for
    his work. J.A. 489. This figure represents about half of
    Endocraft’s net sales ($1.72 million), after appropriate de-
    ductions. J.A. 1006.
    Given these undisputed facts, there is no reasonable
    basis for inferring Mr. DeVona was anything other than an
    employee whose payment was meant to be commensurate
    with the sales of the company. Therefore, the evidence of
    the parties’ respective financial/labor contributions indi-
    cates no partnership existed after Endocraft formed.
    3
    The indicia regarding control over assets further con-
    firms that there was no continued partnership. It is undis-
    puted that Endocraft was owned entirely by Dr. Zeitels.
    J.A. 1187 (listing Dr. Zeitels as the “President” and “sole
    member” representing all ownership interest in Endo-
    craft). On the application for a line of credit regarding the
    business, Dr. Zeitels was listed as owning 100% of Endo-
    craft, while Mr. DeVona’s ownership stake was listed as
    0%. J.A. 1205. This point was punctuated by the ISRA,
    which stated that Mr. DeVona was not a “partner” in En-
    docraft. J.A. 1196 (¶ 12).
    In Mr. DeVona’s view, Dr. Zeitels total ownership of
    Endocraft is inconsequential to the question of partner-
    ship. As previously discussed, Mr. DeVona insists that En-
    docraft was merely the manufacturing arm of some greater
    business. Appellant Br. 37–38. But the trial record pro-
    vides no support for that statement. The evidence is con-
    sistent that Endocraft was the only manifestation of the
    medical device manufacturing business between Mr.
    DeVona and Dr. Zeitels. Indeed, neither at trial, nor in
    post-trial briefing, nor on appeal now does Mr. DeVona
    point to any other relevant company, venture, or vehicle for
    16                                             DEVONA v. ZEITELS
    the business. In short, Endocraft was the business. Dr.
    Zeitels was sole owner of that business.
    There is simply no evidence under this indicia that a
    partnership existed after 1999.
    4
    Turning to the next indicia, the record was plain that
    Dr. Zeitels had exclusive control over the ultimate manage-
    ment decisions at Endocraft. Despite the managerial deci-
    sions Mr. DeVona oversaw as an employee wearing many
    hats, the written record confirms that Mr. DeVona himself
    repeatedly acknowledged Dr. Zeitels’s final control of busi-
    ness decisions. As Endocraft was the sole vehicle for the
    business, Dr. Zeitels thus exercised control over the entire
    business.
    In a 2003 email, Mr. DeVona admitted: “Our deal at
    Endocraft and your position as absolute head of the com-
    pany as [its] creative/seminal/driving force person is une-
    quivocal for me.” J.A. 1243; J.A. 541. On December 6,
    2007, Mr. DeVona admitted to Dr. Zeitels, “I tend to be re-
    ally persistent about some things when I feel I’m right. But
    as [my wife] reminded me with an intellectual slap to the
    back of the head, it’s your company . . . .” J.A. 1244; J.A.
    539.
    The ISRA further cements that Dr. Zeitels exercised
    exclusive control over the highest order decisions. Mr.
    DeVona’s role in the business decisions was cabined by the
    ISRA to that of a manager-level employee. This lack of
    shared authority is contrary to the rights enjoyed by part-
    ners under Rhode Island law. Under the ISRA:
    •   Dr. Zeitels retained authority as owner to determine
    the material aspects of the business. See, e.g.,
    J.A. 1192–96 (¶¶ 2, 5(a), 6(a), 6(d), 7, 8(b), 8(c), 11);
    see also J.A. 1243. If Mr. DeVona was a partner, he
    would presumptively have “equal rights in the
    DEVONA v. ZEITELS                                          17
    management and conduct of the partnership busi-
    ness.” R.I. Gen. Laws § 7–12–29(5).
    •   Similarly, under the ISRA, Mr. DeVona could “make
    no warranties or representations with respect to the
    products,” and neither party had “any authority to
    bind the other in any respect.” J.A. 1195 (¶ 10);
    J.A. 1196 (¶ 12). But a partnership is bound by the
    statements of its partners. See R.I. Gen. Laws §§ 7–
    12–20, 7–12–22.
    •   Finally, the ISRA was “at will.” Dr. Zeitels could ter-
    minate Mr. DeVona from the alleged partnership’s
    only business venture at “any time” in his “sole dis-
    cretion with or without cause.” J.A. 1193 (¶ 5(a)); see
    also J.A. 1209.
    In sum, the ISRA confirms that Mr. DeVona was an
    employee, had no ownership in Endocraft, and was subject
    to termination at any time. Mr. DeVona’s acceptance of the
    ISRA cannot be reconciled with his claim that a partner-
    ship existed.
    In an attempt to do so, Mr. DeVona argues that his May
    18, 1999, letter to Dr. Zeitels evidences his fears about the
    ISRA and his need for assurance the partnership would
    continue. In particular, Mr. DeVona points to his state-
    ment that the ISRA “is just an inaccurate representation
    of what I’ve been doing for the last year to earn my 40%.”
    J.A. 1173; see also J.A. 970. Mr. DeVona seeks the infer-
    ence that by referencing 40% here, he was asserting to Dr.
    Zeitels that he is entitled to a 40% share of the company on
    top of his 40% sales income under the ISRA.
    This inference is unsupported. Mr. DeVona’s letter
    makes no reference to a share of Endocraft. Instead, it only
    involves a detailed discussion of the “risks” and “benefits”
    he believes justify his reward—40% of net sales from the
    instruments. See J.A. 1174–77. The letter goes on to ex-
    plain why he wanted to document the reasons justifying his
    18                                          DEVONA v. ZEITELS
    high sales commission. J.A. 1174 (“If it misleadingly de-
    fines what I’ve done . . . in exchange for such a high per-
    centage of a commission, my earnings might be
    misconstrued legally as an unearned and indefensible gift
    and not a subcontract.”). These statements about his sales
    commission do not evidence a share in an umbrella part-
    nership.
    Mr. DeVona also points to portions of the letter in
    which he spelled out a laundry list of reasons why he felt
    inadequately protected under the ISRA. These concerns,
    however, only underscore the absence of an existing um-
    brella partnership. Mr. DeVona wrote, “My downside has
    no coverage, no patent share if it is sold later, no share in
    the company, no exclusive rights or licensing share in this
    agreement.” J.A. 1176. “You could . . . hypothetically give
    me notice and replace me immediately once all my work is
    done.” 
    Id. As Mr.
    DeVona’s statements confirm, his involvement
    in the business could end at any time and if the company
    was sold he would take no share of the proceeds. A partner
    would not encounter such issues. Had there been an en-
    during umbrella partnership above Endocraft, such protec-
    tions would already exist. For example, Mr. DeVona’s
    concern that he had “no share in the company” would be
    irrelevant if an umbrella partnership existed since he
    would still be entitled to his 40% share of the partnership.
    Nowhere in the letter does Mr. DeVona assert he has such
    rights.
    To further explain his decision to sign the ISRA, Mr.
    DeVona points to his testimony that Dr. Zeitels assured
    him their “underlying agreement that we were partners”
    would remain unchanged and the “umbrella of the partner-
    ship is still there.” J.A. 333; J.A. 340. After fully crediting
    this testimony, J.A. 10, the district court concluded that the
    evidence of “the subsequent conduct of the parties” points
    “so strongly and overwhelmingly in favor of Zeitels that no
    DEVONA v. ZEITELS                                           19
    reasonable jury could have found a continuing partnership
    after May 1999.” 
    Id. We agree.
        Aside from this piece of testimony from Mr. DeVona
    and a vague statement from his friend, Steve Fusco, see su-
    pra 21, there is a remarkable lack of any real indicia of
    partnership under Rhode Island law in the twelve years
    that followed Mr. DeVona’s decision to execute the ISRA.
    In light of this record, this threadbare testimony about
    what Dr. Zeitels said before Mr. DeVona signed the ISRA
    cannot support the conclusion that the partnership contin-
    ued.
    In Mr. DeVona’s view, such testimony alone can suffice
    to sustain a verdict. But Mr. DeVona’s reliance on Gabri-
    elle v. Marini, 
    80 R.I. 458
    (1953), is misplaced. In Gabri-
    elle, the plaintiff testified to the existence of a partnership
    for a restaurant. But there was simply no counterevidence.
    
    Id. at 463
    (“[T]he evidence of that fact . . . appears to be
    undisputed.”). Not only did the defendant in Gabrielle de-
    cline to offer any testimony, but there was also no mention
    of any other counter evidence, such as written records. See
    
    id. In concluding
    there was no clear error in finding a part-
    nership, Gabrielle emphasized that “the evidence is uncon-
    tradicted” that “funds contributed by both parties were
    employed in the common enterprise with the express un-
    derstanding that the profits thereof were to be shared
    equally.” 
    Id. Based on
    the record evidence, it was also un-
    disputed that the parties were both on the hook for any
    losses. 
    Id. (“While nothing
    was said about losses in excess
    of the capital invested there can be no question that they
    too would have to be shared.”).
    Here, there is extensive written evidence and addi-
    tional testimony from Mr. DeVona himself—who agreed no
    partnership records were kept or profits/losses shared—
    that directly contradicts the existence of a true partner-
    ship. Moreover, as to the issue at hand, there is no dispute
    20                                         DEVONA v. ZEITELS
    that Dr. Zeitels exercised ultimate control over Endocraft
    decisions.
    Thus, in light of the ISRA and the surrounding record
    evidence, there is no record of shared management.
    5
    Finally, we address the remaining indicia, including
    tax returns, partnership name, and representations to
    third parties. Courts applying Rhode Island law have con-
    cluded that no partnership exists where, inter alia, the par-
    ties “did not file partnership taxes” and did not “operate
    under a shared name.” T.G. Plastics Trading Co. Inc. v.
    Toray Plastics (Am.), Inc., 
    958 F. Supp. 2d 315
    , 328 (D.R.I.
    2013).
    Mr. DeVona does not dispute that the purported part-
    nership never filed a single tax return. Nor did it issue a
    form K-1. J.A. 497–99. Rather, each year Dr. Zeitels ap-
    pears to have reported all of Endocraft’s income on his per-
    sonal taxes and paid its income tax. See J.A. 661; J.A. 683.
    Likewise, Mr. DeVona further concedes that there is no
    evidence a partnership conducted any business in its own
    name after Endocraft formed. There are no invoices, bills,
    bank statements, letters, internal memos, or records of any
    kind.
    Ignoring the empty record, Mr. DeVona contends the
    district court’s decision is flawed because it did not address
    how Mr. DeVona and Dr. Zeitels “held themselves out to
    third parties.” J.A. 1110–11; 
    Southex, 279 F.3d at 99
    , 101–
    103. Mr. DeVona relies on a handful of communications in
    which he and Dr. Zeitels were referred to as partners in
    passing. For example, prior to the meeting in April 1999,
    ACT Medical employees sent a fax to Dr. Zeitels’s attorney
    indicating that they were “look[ing] forward to meeting
    with Dr. Zeitels & his partner.” J.A. 965; J.A. 1160. Ac-
    cording to Mr. DeVona, Dr. Zeitels introduced him as his
    partner at the meeting with ACT Medical. J.A. 330.
    DEVONA v. ZEITELS                                          21
    Finally, Mr. DeVona’s friend, Mr. Fusco, testified that he
    once overheard Dr. Zeitels tell Mr. DeVona that they “were
    partners” and “when we sell the company, you’re going to
    get a check for like a million dollars” during a conversation
    at a space he shared with Mr. DeVona in Providence some
    time “in the late ‘90s, early 2000, in that range.” J.A. 595;
    J.A. 602–603.
    This evidence fails to confirm that a partnership ex-
    isted for several reasons. First, most (if not all) of these
    statements occurred before the parties switched gears and
    formed Endocraft in May 1999.
    Second, “[i]t is well settled that the use of the word
    ‘partner’ in the colloquial sense is insufficient as a matter
    of law to establish a legal partnership.” CDS, Inc. v.
    Karndean Int’l, LLC, No. CV 15-148M, 
    2017 WL 1379603
    ,
    at *10 (D.R.I. Mar. 17, 2017), report and recommendation
    adopted, No. 15-CV-148-M-PAS, 
    2017 WL 1383672
    (D.R.I.
    Apr. 14, 2017); see also T.G. 
    Plastics, 958 F. Supp. 2d at 327
    –28 (“[T]he use of the word ‘partner’ or ‘partnership’ col-
    loquially in emails by executives of either company does lit-
    tle to establish that a legal partnership existed.”).
    Third, for a partnership that purportedly lasted for a
    dozen years after the formation of Endocraft, Mr. DeVona
    musters a handful of instances in which the parties are de-
    scribed as “partners” in some sense. Otherwise, the record
    of written emails to vendors, purchasers, and even between
    the parties themselves over the years is completely devoid
    of any official mention of Mr. DeVona as a partner. With-
    out more, a few references to Mr. DeVona as a partner or
    colleague cannot fill the void of more than a decade of si-
    lence with no records or other indicia from the activities of
    a genuine partnership operating above Endocraft.
    For the reasons above, the district court did not err in
    concluding that no reasonable jury could conclude a part-
    nership continued after the formation of Endocraft in 1999.
    22                                         DEVONA v. ZEITELS
    B
    Mr. DeVona next argues that the district court improp-
    erly excluded a 2011 email. In the email, Mr. DeVona
    wrote to his attorney to discuss the purported partnership
    after Endocraft was sold. According to Mr. DeVona, this
    evidence was admissible because “[w]hen a witness, on the
    stand and under oath, acknowledges that a prior statement
    is his own statement and is truthful, then the witness
    adopts the prior statement as his present testimony and
    there is no hearsay problem.” Amarin Plastics, Inc. v. Md.
    Cup Corp., 
    946 F.2d 147
    , 153 (1st Cir. 1991).
    Mr. DeVona’s argument is unpersuasive for two rea-
    sons. First, Mr. DeVona failed to raise this exclusion to
    hearsay as a basis for admitting the evidence at trial. See
    J.A. 377 (arguing only that the exhibit was admissible un-
    der the business records exception). As such, this argu-
    ment was waived. See Boggs v. West, 
    188 F.3d 1335
    , 1337–
    38 (Fed. Cir. 1999). Second, there is a lack of foundation
    for this exclusion. Mr. DeVona never testified that his
    statements in the 2011 email were truthful, see J.A. 376–
    78, which courts universally recognize is required to trigger
    this exclusion. See 
    Amarin, 946 F.2d at 153
    (collecting
    cases); see also Fed. R. Evid. 801 advisory committee’s note
    (d)(1) (if declarant “admits on the stand that he made the
    statement and that it was true,” there is no hearsay prob-
    lem).
    C
    Finally, Mr. DeVona argues that the district court
    abused its discretion by conditionally granting a new trial.
    We review the grant of a new trial for abuse of discretion.
    Latin Am. Music Co. v. Media Power Grp., Inc., 
    705 F.3d 34
    , 40 (1st Cir. 2013). “A trial court may grant a new trial
    on the basis that the verdict is against the weight of the
    evidence,” as well as “whenever, in its judgment, the action
    is required in order to prevent injustice.” Jennings v.
    Jones, 
    587 F.3d 430
    , 436 (1st Cir. 2009). In contrast to
    DEVONA v. ZEITELS                                         23
    JMOL, the district court may independently weigh the ev-
    idence when considering a motion for a new trial, Uniloc
    USA, Inc. v. Microsoft Corp., 
    632 F.3d 1292
    , 1310 (Fed. Cir.
    2011) (applying First Circuit law), and “may consider . . .
    the credibility of the witnesses,” Valentin-Almeyda v. Mu-
    nicipality of Aguadilla, 
    447 F.3d 85
    , 104 (1st Cir. 2006).
    Based on the clear lack of evidence of a partnership, the
    district court did not abuse its discretion in concluding the
    jury’s conclusion was against the weight of the evidence.
    CONCLUSION
    For the foregoing reasons, we affirm the district court’s
    decision granting judgment as a matter of law, excluding

    Appeal from the United States District Court for the

    ______________________
    CLEVENGER, Circuit Judge, dissenting.
    Dennis DeVona and Stephen Zeitels once were close
    friends, so much so that DeVona officiated at the Zeitels’
    wedding. DeVona is a skilled designer, tool maker and
    manufacturer. Zeitels is a throat surgeon. The two bonded
    over a shared passion for antiques. Zeitels came up with
    the idea for an improved glottiscope, a device used by
    throat surgeons to access the larynx during surgery.
    Zeitels convinced DeVona to assist in development of the
    2                                          DEVONA v. ZEITELS
    new product. DeVona gave up his previous employment
    and worked full-time on developing the new device. Zeitels
    provided all the money to fund the project. When the two
    realized that it would be quite expensive to outsource pro-
    duction of the new device, Zeitels created a new, wholly
    owned, corporation to develop and sell the new device.
    Zeitels determined that DeVona should become an inde-
    pendent sales representative under contract with the cor-
    poration. Zeitels also made DeVona vice president of the
    corporation. The business in time became profitable. In
    October of 2011, Zeitels informed DeVona that he was clos-
    ing the corporation and taking its assets. From the start of
    the undertaking until it was shut down in 2011, Zeitels
    maintained his medical practice full time, and DeVona de-
    voted himself full time to running the business.
    DeVona sued Zeitels in the U.S. District Court in Mas-
    sachusetts, claiming that he and Zeitels had formed a part-
    nership in 1997, that Zeitels had wrongfully terminated
    the partnership in 2011, and that Zeitels owed him dam-
    ages for the wrongful termination.
    At trial, the jury was presented with two strikingly dif-
    ferent characterizations of the relationship between Zeitels
    and DeVona. Zeitels, throughout the trial, adamantly in-
    sisted that he never agreed to be DeVona’s partner. At
    most, DeVona would have been an employee, but never a
    partner. DeVona’s understanding was entirely different.
    DeVona told the jury that, at the very beginning, he
    insisted to Zeitels that he would only become involved in
    the project as a full equity partner. DeVona told the jury
    that he met in Boston with Zeitels, and both agreed to be
    partners, with the terms of the partnership being “[w]e
    would split 60/40. He would put up the money. I would
    put up the energy and work it would take. And we’d try
    and knock it out in 12 months . . . I should do the work, and
    we were going to go forward with a business. Whatever we
    developed we’d sell and, hopefully, quick.” J.A. 245. A third
    DEVONA v. ZEITELS                                           3
    party told the jury that he had overheard Zeitels telling
    DeVona that they “were partners,” and that in the end
    DeVona “would get a check for like a million dollars.” J.A.
    595.
    DeVona testified about how his efforts resulted in the
    first prototype of the new device, how he and Zeitels came
    to learn that outsourcing manufacture of the device would
    be too expensive, and how, as a result, the two “switched
    gears” in 1999 to proceed in-house. J.A. 414. Zeitels cre-
    ated the corporation to shield himself from any liability
    that might arise from manufacture of the new device, and
    insisted on formalization of DeVona’s relationship with the
    corporation. DeVona testified that Zeitels told him that the
    independent sales representative agreement “did not
    change the underlying relationship. The umbrella partner-
    ship is still there and that whenever we make and sell this
    stuff is going to be – that’s when we were going to end
    it…[W]hen we sell the company.” Trial Tr. 2-129:13-16.
    When asked if he and Zeitels discussed whether the new
    corporation affected their relationship, DeVona testified
    that Zeitels assured him that the corporation did not
    change the underlying agreement that they were partners,
    saying “it doesn’t change a single thing.” J.A. 333.
    By the close of evidence, the jury heard two utterly dif-
    ferent stories about the relationship of DeVona and Zeitels
    in the ongoing effort to create and sell a business built
    around a new medical device. As the trial proceeded, each
    side sought to undermine the other’s credibility. Since
    there was no written evidence to show the existence of a
    partnership, the jury was left with only the testimony of
    the two men, and a few tidbits of possible partnership indi-
    cia, such as the joint bank account holding Zeitels’ money.
    To be sure, beyond the testimony of the two men about
    their relationship, the evidence was thin on the traditional
    indicia of partnership. If the jury could find a partnership
    here, it would have to credit DeVona’s testimony over
    Zeitels’.
    4                                           DEVONA v. ZEITELS
    In a case such as this where there is no intrinsic evi-
    dence of a partnership agreement, a partnership would de-
    pend on extrinsic evidence, and under Rhode Island law,
    the existence of an extrinsic evidence-based partnership is
    a question of fact, not a question of law. See T.G. Plastics
    Trading Co. v. Toray Plastics (Am.), Inc., 
    958 F. Supp. 2d 315
    , 327 (D.R.I. 2013) (stating that “when a party has ex-
    trinsic evidence supporting the existence of a partnership,
    . . . whether the partnership actually exists” is a question
    of fact); Cheetham v. Cheetham, No. C.A. 71–575, 
    1979 WL 196028
    , at *9 (R.I. Super. Ct. July 16, 1979) (“The existence
    of a partnership relation is a question of intention to be
    gathered from all of the facts and circumstances revealed
    by the evidence.”); Acinapura v. Natalizia, No. PC 1999-
    2007, 
    2003 WL 22048717
    , at *4 (R.I. Super. July 30, 2003)
    (discussing that, in partnership cases, “the parties’ intent
    should be ascertained as a question of fact”).
    Before the jury retired, Zeitels filed a Rule 50(a) motion
    for judgment as a matter of law on three grounds. First,
    regarding whether there was a partnership of any kind at
    all, the motion insisted that there were insufficient facts to
    show any partnership under the governing Rhode Island
    law. Second, if there was a partnership for a particular
    undertaking (creating and selling a business), the under-
    taking was “frustrated or prevented by the mediocre work
    by Mr. DeVona and his failure to make [the corporation],
    the sole asset, viable or marketable to a buyer. That frus-
    tration of purpose excuse[d] Dr. Zeitels from liability for
    withdrawing from the alleged partnership.” D. Mass. Dkt.
    No. 263 at 19. Third, if a partnership existed, it was one at
    will, which could be dissolved by either party at any time
    for any reason. The record at trial supplied a basis for the
    first ground for the Rule 50(a) motion, because the parties
    plainly disputed whether they entered a partnership. The
    record, however, did not support either of the other
    grounds, because the jury never heard any evidence to sup-
    port a distinction between types of partnership, and no jury
    DEVONA v. ZEITELS                                          5
    charge was given on that subject. The district court denied
    the Rule 50(a) motion and the case went to the jury.
    The jury returned a verdict for DeVona giving him all
    he asked for on his breach of partnership claim. To do so,
    the jury had to conclude that a partnership existed until
    Zeitels destroyed the partnership by closing the business.
    To reach that conclusion, the jury had to believe DeVona
    over Zeitels, which included believing DeVona’s testimony
    that the shift in gears had no effect on the partnership.
    Zeitels then filed a renewed motion for judgment as a
    matter of law pursuant to Rule 50(b). Because the law pre-
    vents a Rule 50(b) motion on any ground not raised in the
    Rule 50(a) motion, Cornwell Entm't, Inc. v. Anchin, Block
    & Anchin, LLP, 
    830 F.3d 18
    , 28 (1st Cir. 2016), Zeitels’
    Rule 50(b) motion only repeated the grounds for the Rule
    50(a) motion: There was insufficient evidence for the jury
    to find any partnership, but if a partnership for a particu-
    lar undertaking existed, it was breached by actions of
    DeVona, or, alternatively, if a partnership at will existed,
    Zeitels was free to dissolve it. Zeitels’ memorandum in sup-
    port of the Rule 50(b) motion, however, raised a new
    ground for upsetting the jury verdict. The memorandum
    argued that the switching of gears in 1999 to bring the pro-
    ject in-house changed the particular undertaking, and
    thereby dissolved the original partnership and converted it
    to a partnership at will which Zeitels was free to dissolve.
    The district court granted the Rule 50(b) motion. The
    district court held that the jury was free to find a partner-
    ship for a particular undertaking to “create a company or a
    surgical device and to sell that device or company, or the
    intellectual property associated therewith, to the highest
    bidder in the shortest amount of time possible.” J.A. 7. The
    district court next posited that under Rhode Island law, a
    partnership for a particular undertaking dissolves by the
    termination of the particular undertaking. Next, although
    in agreement that the evidence supported a partnership for
    6                                          DEVONA v. ZEITELS
    a particular undertaking at the start, the district court,
    without citing any testimony, held, as a matter of fact, that
    any such partnership dissolved when the partners agreed
    in 1999 to switch gears by taking the project in-house.
    The district court then addressed the evidence de-
    scribed above directed to the switching of gears to take the
    business in-house, namely that the switching of gears had
    no effect on the partnership. The district court purported
    to “accord those statements full weight.” J.A. 10. But, in-
    stead of crediting that evidence to show that the switch in
    gears had not dissolved the partnership (which is of course
    the only purpose for which the testimony was given, and
    the only reason for which it could be given weight), the dis-
    trict court instead characterized that evidence as having
    been offered by DeVona to show a continuing partnership
    after the purported dissolution of the partnership as a re-
    sult of the gear change. As such, the district court held that
    DeVona’s evidence did not support a continued partnership
    after the putative dissolution.
    Without question, the district court committed plain
    error twice. First, the district court sua sponte dissolved
    the admitted partnership for a particular purpose, due to
    the shift in gears, even though the only testimony on the
    subject was that the change in gears was of no conse-
    quence. Second, and related, the district court gave full
    weight to DeVona’s testimony for the wrong reason. In-
    stead of giving weight to the proposition that the switch in
    gears did not affect the underlying partnership, and there-
    fore that the original partnership for a particular under-
    taking survived the gear switch, the district court turned
    the very same evidence against DeVona, by saying it was
    insufficient to show a new partnership after the court per-
    sonally dissolved the original partnership.
    If the original partnership was not dissolved, there is
    no reason to ask if the indicia after 1999 (which essentially
    did not change: Zeitels put up all the money and DeVona
    DEVONA v. ZEITELS                                           7
    did all the work) would support a new partnership. The
    new partnership notion is a red herring, a made-up ground
    to deny DeVona his constitutional right to a fair jury trial.
    If the district court (and the majority here) gave full weight
    to the testimony in DeVona’s favor, there is no basis to bar
    the jury from finding that the switch in gears had no effect
    on the partnership. See Crowe v. Bolduc, 
    334 F.3d 124
    , 134
    (1st Cir. 2003) (noting that, when considering a motion for
    judgment as a matter of law, district courts are required to
    weight their review “toward preservation of the jury ver-
    dict”).
    In this credibility contest between the word of DeVona
    on the one hand, and Zeitels on the other, the only question
    of relevance is whether DeVona’s testimony that the
    change in gears had no effect on the underlying partner-
    ship was properly credited by the district court in deciding
    the Rule 50(b) motion. Because my respected colleagues in
    the majority endorse the plain error committed by the dis-
    trict court, I must dissent. DeVona is wrongly deprived of
    his jury verdict.
