    2             CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    Before PROST, Chief Judge, WALLACH and HUGHES,
    Circuit Judges.
    PROST, Chief Judge.
    Plaintiffs-appellants CODA Development s.r.o., CODA
    Innovations s.r.o. (together, “Coda”), and Frantisek Hrabal
    (collectively, “Plaintiffs”) filed a complaint against defend-
    ants-appellees The Goodyear Tire & Rubber Company
    (“Goodyear”), Robert Benedict, and Robert Losey (collec-
    tively, “Defendants”) in the U.S. District Court for the
    Northern District of Ohio. The complaint sought correction
    of inventorship in several Goodyear patents and alleged,
    among other things, that Goodyear misappropriated
    Coda’s trade secrets.
    The district court dismissed the complaint for failing to
    state a claim upon which relief could be granted, and fol-
    lowing the dismissal, it denied Plaintiffs leave to amend
    their complaint. Plaintiffs appeal the district court’s dis-
    missal and denial of leave to amend. We vacate the district
    court’s dismissal and remand for further proceedings con-
    sistent with this opinion.
    BACKGROUND
    I
    The complaint alleges the following facts. Mr. Hrabal,
    Coda’s CEO, invented certain self-inflating tire (“SIT”)
    technology. In 2008, General Motors representatives ap-
    proached Coda and expressed interest in the technology.
    General Motors wanted to involve Goodyear in commercial-
    izing the technology, and Coda consented to that arrange-
    ment. General Motors then wrote to Goodyear suggesting
    that it contact Coda, which it did. Goodyear requested and
    arranged a meeting with Coda, but before the meeting took
    place, the parties executed a nondisclosure agreement re-
    stricting use of disclosed information to cooperation
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                  3
    between the parties regarding the development of SIT tech-
    nology.
    Coda and Goodyear met for the first time on January
    15, 2009, at a research facility near Frankfurt, Germany.
    Several Goodyear representatives participated in the meet-
    ing, including Mr. Benedict, who was responsible for Good-
    year’s research and development relating to SIT
    technology. At this meeting, and at Goodyear’s request,
    Coda shared novel, proprietary, and confidential infor-
    mation concerning its SIT technology, including the place-
    ment of the tire’s pump tube, the design of the pressure
    management system, the efficiency of the leakage compen-
    sation system, and the air passageway/interface between
    the exterior and interior of the tire. 1 J.A. 55–56 ¶¶ 29, 31.
    Some Goodyear representatives expressed skepticism
    about the viability of Coda’s technology. Goodyear had
    been disappointed before; it previously invested in a failed
    inflating technology called the “Cycloid.” Nevertheless,
    Coda addressed Goodyear’s viability concerns at this meet-
    ing, and the parties agreed to continue discussions.
    Goodyear contacted Coda requesting a second meeting.
    Mr. Benedict specifically requested to review an updated
    technical presentation, the latest product, testing methods,
    and performance results. J.A. 56–57 ¶ 34. This second
    meeting occurred in Prague on June 15, 2009, with Mr.
    Benedict and members of his team in attendance. At this
    meeting, Coda allowed Goodyear to examine a functional
    prototype of Coda’s SIT technology. Mr. Benedict re-
    quested that he and his team be allowed to spend some
    time alone with the prototype, during which he photo-
    graphed it without permission. J.A. 57 ¶ 36.
    1   Separately, the complaint notes that the pump
    tube is “preferably located in the tire sidewall.” J.A. 53
    ¶ 20.
    4            CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    Following the June 2009 Prague meeting, several
    months passed without any communication from Good-
    year. Coda attempted to restart communications in No-
    vember 2009, inviting Mr. Benedict to dinner to discuss the
    status of the proposed development project. Mr. Benedict
    declined, saying that “[a] meeting would be premature at
    this point.” J.A. 58 ¶ 38 (alteration in original).
    The following month, December 2009, a Goodyear em-
    ployee on Mr. Benedict’s team independently contacted
    Coda to inquire about the status of Coda’s SIT technology
    in preparation for an internal Goodyear meeting. Coda ex-
    plained that Mr. Benedict had surprisingly gone silent.
    The employee replied, saying that “during [Goodyear’s]
    brainstorm session, I indicated your invention matches up
    nicely with Goodyear’s current criteria for development
    and asked if we have looked into this with SIT Coda. [Mr.
    Benedict’s] response to this question was oddly vague.”
    J.A. 58 ¶ 40 (first alteration in original).
    Also that month, and unbeknownst to Coda, Goodyear
    applied for a patent entitled “Self-Inflating Tire Assembly.”
    Goodyear’s application published on June 23, 2011, issued
    as U.S. Patent No. 8,042,586 (the “’586 patent”) on October
    25, 2011, and named Messrs. Benedict and Losey as the
    inventors.
    Meanwhile, Coda assumed that Goodyear’s silence in-
    dicated a lack of interest in Coda’s SIT technology, or per-
    haps that the economic recession was inhibiting further
    discussions. But in September 2012, Coda received an un-
    solicited email from the (then ex-) Goodyear employee with
    whom Coda corresponded in December 2009. The email
    said, “I am retired now from Goodyear and see in the news
    today that they have copied your SIT. Unfortunate. I
    thought China companies were bad.” J.A. 59 ¶ 44.
    According to the complaint, between 2012 and 2015,
    eleven other patents issued to Goodyear covering assem-
    blies and methods for assembly of pumps and other devices
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                  5
    used in self-inflating tires. The complaint alleges that
    these patents have claims with limitations covering the
    novel, proprietary, and confidential information Coda dis-
    closed to Goodyear.
    II
    Plaintiffs sued Defendants in the U.S. District Court
    for the Northern District of Ohio on August 9, 2015. The
    complaint included two correction-of-inventorship claims
    concerning the ’586 patent—one to add Mr. Hrabal as an
    inventor, the other to remove Messrs. Benedict and Losey
    as inventors. The complaint also included correction-of-in-
    ventorship claims to add Mr. Hrabal as an inventor on
    eleven other Goodyear patents (the “Alleged Jointly In-
    vented Patents”) 2 and a claim of trade-secret misappropri-
    ation under Ohio state law.
    Defendants moved to dismiss under Federal Rule of
    Civil Procedure 12(b)(6). Defendants argued that for each
    of Plaintiffs’ correction-of-inventorship claims, the com-
    plaint failed to plead facts supporting Mr. Hrabal’s concep-
    tion or co-conception of the inventions claimed in
    Goodyear’s patents. Defendants referenced an exhibit to
    their motion—a patent application of Mr. Hrabal’s pub-
    lished before the ’586 patent’s filing date—and argued that
    the complaint’s description of Plaintiffs’ novel, confidential
    technology was “so unspecific that it applie[d] equally” to
    this publication. J.A. 273. With respect to the Alleged
    Jointly Invented Patents, Defendants further argued that
    the complaint failed to plead facts supporting collabora-
    tion. Finally, Defendants argued that Plaintiffs’ trade-se-
    cret-misappropriation claim was barred by the relevant
    2  The Alleged Jointly Invented Patents are U.S. Pa-
    tent Nos. 8,235,081; 8,322,036; 8,381,784; 8,550,137;
    8,573,270; 8,695,661; 8,944,126; 8,857,484; 8,746,306;
    8,381,785; and 8,113,254. J.A. 65–71.
    6             CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    Ohio statute of limitations because Coda should have
    known of its claim as of June 2011, when the application
    leading to the ’586 patent published.
    Plaintiffs opposed. In reply, Defendants attached an
    article written by Mr. Hrabal that was published in No-
    vember 2008 (the “Hrabal article”). J.A. 874–78. Defend-
    ants argued that the Hrabal article publicly disclosed
    everything the complaint alleged was novel, proprietary,
    and confidential (and shared with Goodyear), including the
    placement of the tire’s pump tube, the design of the pres-
    sure management system, the efficiency of the leakage
    compensation system, and the air passageway/interface be-
    tween the exterior and interior of the tire. J.A. 844–45.
    Plaintiffs moved the district court to strike or disregard
    the Hrabal article because it was outside the pleadings and
    was offered for the first time on reply. Alternatively, Plain-
    tiffs requested leave to file a sur-reply addressing the new
    arguments based on the Hrabal article. In their request
    for a sur-reply, Plaintiffs argued that while the Hrabal ar-
    ticle disclosed a location for the tire’s pump tube, that loca-
    tion was not the secret location disclosed to Goodyear.
    Plaintiffs indicated that a sur-reply would fully explain
    why the Hrabal article did not disclose the alleged novelty
    and trade secrets that Coda disclosed to Goodyear.
    Nine months after briefing on the motion to dismiss
    concluded, the district court issued an opinion and order
    denying Plaintiffs’ motion to strike and granting Defend-
    ants’ motion to dismiss. Coda Dev. s.r.o. v. Goodyear Tire
    & Rubber Co., No. 5:15-cv-1572, 
    2016 WL 5463058
    (N.D.
    Ohio Sept. 29, 2016) (“Dismissal Opinion”). The court de-
    nied Plaintiffs’ motion to strike because it found the Hrabal
    article was judicially noticeable as a “2008 public disclo-
    sure of something [Plaintiffs] now claim[] was secret when
    disclosed to Goodyear in 2009.” 
    Id. at *2.
    The court’s opin-
    ion did not explain why it denied Plaintiffs’ alternative re-
    quest to file a sur-reply addressing the new article.
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                   7
    The district court then addressed Defendants’ motion
    to dismiss. Beginning with Plaintiffs’ correction-of-inven-
    torship claims, the court set forth the alleged disclosures to
    Goodyear and found that Goodyear’s ’586 patent “actually
    identifies these very concepts as ‘prior art,’” and that Mr.
    Hrabal’s prior, published patent application disclosed a
    pump tube in a side wall. 
    Id. at *4–5.
    But the bulk of the
    court’s prior-art analysis rested on the Hrabal article. The
    court adopted Defendants’ mapping of the article’s contents
    to the complaint’s description of the elements disclosed to
    Goodyear and concluded that the article publicly disclosed
    each of those elements. 
    Id. 3 The
    court also concluded that
    the complaint did not plausibly show that Mr. Hrabal was
    the sole inventor of the subject matter claimed in the ’586
    patent or that he “contributed in any way, much less a
    novel way,” to the Alleged Jointly Invented Patents. See
    
    id. at *5–6.
    Further, concerning the Alleged Jointly In-
    vented Patents in particular, the court concluded that the
    complaint undermined the necessary showing of collabora-
    tion because it alleged that Goodyear stopped communi-
    cating with Coda after the Prague meeting. 
    Id. at *5.
    On
    these bases, the court dismissed Plaintiffs’ correction-of-in-
    ventorship claims.
    The district court also dismissed Plaintiffs’ trade-se-
    cret-misappropriation claim as time-barred under Ohio’s
    four-year statute of limitations. 
    Id. at *11;
    see 
    id. at *9–10.
    The court found that the facts alleged in the complaint—
    including those concerning the two Goodyear meetings, the
    subsequent silence from Goodyear, and the independent
    contact from a Goodyear employee concerning Goodyear’s
    internal meeting—“should have been sufficient notice to
    plaintiffs that something might have been amiss,” thus
    3   The court’s mapping is not printed in the currently
    available Westlaw version of the Dismissal Opinion, but it
    can be found in the table at J.A. 25.

    triggering a duty to investigate. 
    Id. at *10
    (emphasis in
    original). According to the court, had Plaintiffs investi-
    gated, they would have discovered the application leading
    to the ’586 patent at least as of its June 23, 2011 publica-
    tion date—more than four years before the complaint’s Au-
    gust 9, 2015 filing date. 
    Id. The court
    therefore dismissed
    Plaintiffs’ trade-secret-misappropriation claim. 4
    Plaintiffs moved the court to amend the judgment un-
    der Federal Rule of Civil Procedure 59(e) and also for leave
    to file an amended complaint. 5 The proposed amended
    complaint provided additional factual allegations regard-
    ing the SIT information disclosed to Goodyear, including
    the specific location of the tire’s pump tube and how that
    location differed from the prior art. In this respect, the pro-
    posed amended complaint alleged that Mr. Hrabal “com-
    municated to Goodyear the idea to put a tube in a groove in
    4    The district court dismissed all claims in the com-
    plaint, but Plaintiffs appeal the dismissal of only their cor-
    rection-of-inventorship      claims     and     trade-secret-
    misappropriation claim. Appellant’s Br. 23–24, 28, 40;
    Oral       Arg.     at     1:03–20,      No.      2018-1028,
    http://www.cafc.uscourts.gov/oral-argument-recordings
    (“Oral Arg.”).
    5    The proposed amended complaint dropped many
    claims but added others. For example, it maintained cor-
    rection-of-inventorship claims only with respect to the ’586
    patent and a subset of the Alleged Jointly Invented Pa-
    tents, but it added a correction-of-inventorship claim with
    respect to U.S. Patent Nos. 8,826,955 and 8,851,132—nei-
    ther of which was in the original complaint. Additionally,
    it maintained the trade-secret-misappropriation claim and
    added a declaratory-judgment claim regarding the parties’
    interests in certain patents and pending patent applica-
    tions. It dropped all other claims that appeared in the orig-
    inal complaint.
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                  9
    the bending region of the [tire’s] sidewall.” J.A. 137–38
    ¶ 124 (emphasis added); J.A. 92 ¶ 15 (“Mr. Hrabal did not
    include this tube in the sidewall groove embodiment in any
    of his patent applications. . . . and this embodiment was not
    found in any prior art.”).
    Nearly a year after Plaintiffs filed their post-judgment
    motions, the district court denied them. Coda Dev. s.r.o. v.
    Goodyear Tire & Rubber Co., No. 5:15-cv-1572, 
    2017 WL 4271874
    (N.D. Ohio Sept. 26, 2017). The court acknowl-
    edged that the proposed amended complaint set forth
    Plaintiffs’ correction-of-inventorship claims with “amazing
    clarity.” 
    Id. at *6.
    But, in the court’s view, the factual de-
    tails added in the proposed amended complaint—particu-
    larly the specific location of the pump tube—should have
    been in the original complaint. 
    Id. at *5–6.
    Given this
    view, and Plaintiffs’ decision not to request leave to amend
    before judgment, the court declined to allow Plaintiffs a “do
    over” on these claims. 
    Id. at *7.
    The court separately re-
    jected Plaintiffs’ arguments concerning their trade-secret-
    misappropriation claim. 
    Id. at *7–8.
        Plaintiffs appeal the district court’s dismissal of their
    original complaint and denial of their post-judgment re-
    quest for leave to amend the complaint. We have jurisdic-
    tion under 28 U.S.C. § 1295(a)(1).
    DISCUSSION
    We review a district court’s dismissal for failure to
    state a claim under the regional circuit’s law. BASCOM
    Glob. Internet Servs., Inc. v. AT&T Mobility LLC, 
    827 F.3d 1341
    , 1347 (Fed. Cir. 2016). The Sixth Circuit reviews such
    dismissals de novo, “construing the complaint in the light
    most favorable to the plaintiffs, accepting their well-
    pleaded factual allegations as true, and drawing all reason-
    able inferences in their favor.” Allied Erecting & Disman-
    tling Co. v. Genesis Equip. & Mfg., Inc., 
    805 F.3d 701
    , 707
    (6th Cir. 2015) (quoting Russell v. Lundergan-Grimes, 
    784 F.3d 1037
    , 1045 (6th Cir. 2015)). “To survive a motion to
    10            CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    dismiss, a complaint must contain sufficient factual mat-
    ter, accepted as true, to ‘state a claim to relief that is plau-
    sible on its face.’” Ashcroft v. Iqbal, 
    556 U.S. 662
    , 678
    (2009) (quoting Bell Atl. Corp. v. Twombly, 
    550 U.S. 544
    ,
    570 (2007)). “A claim has facial plausibility when the plain-
    tiff pleads factual content that allows the court to draw the
    reasonable inference that the defendant is liable for the
    misconduct alleged.” 
    Id. “Determining whether
    a com-
    plaint states a plausible claim for relief will . . . be a con-
    text-specific task that requires the reviewing court to draw
    on its judicial experience and common sense.” 
    Id. at 679.
        We also review a district court’s denial of a Rule 59(e)
    motion to amend a judgment and a motion to amend the
    complaint under the regional circuit’s law. Alcon Research
    Ltd. v. Barr Labs., Inc., 
    745 F.3d 1180
    , 1192 (Fed. Cir.
    2014) (Rule 59(e) motion to amend a judgment); Advanced
    Software Design Corp. v. Fiserv, Inc., 
    641 F.3d 1368
    , 1380
    (Fed. Cir. 2011) (motion to amend the complaint). The
    Sixth Circuit reviews denial of such motions for abuse of
    discretion. Morse v. McWhorter, 
    290 F.3d 795
    , 799 (6th Cir.
    2002).
    Below, we first discuss the original complaint and the
    district court’s dismissal, analyzing the correction-of-in-
    ventorship and trade-secret-misappropriation claims sepa-
    rately. We then address Plaintiffs’ post-judgment motions.
    I
    A
    Plaintiffs’ complaint sets forth thirteen correction-of-
    inventorship claims under 35 U.S.C. § 256, which states:
    (a) CORRECTION.—Whenever through error a per-
    son is named in an issued patent as the inventor,
    or through error an inventor is not named in an is-
    sued patent, the Director may, on application of all
    the parties and assignees, with proof of the facts
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                  11
    and such other requirements as may be imposed,
    issue a certificate correcting such error.
    (b) PATENT VALID IF ERROR CORRECTED.—The error
    of omitting inventors or naming persons who are
    not inventors shall not invalidate the patent in
    which such error occurred if it can be corrected as
    provided in this section. The court before which
    such matter is called in question may order correc-
    tion of the patent on notice and hearing of all par-
    ties concerned and the Director shall issue a
    certificate accordingly.
    35 U.S.C. § 256 (2012). This section “provides a cause of
    action to interested parties to have the inventorship of a
    patent changed to reflect the true inventors of the subject
    matter claimed in the patent.” Fina Oil & Chem. Co. v.
    Ewen, 
    123 F.3d 1466
    , 1471 (Fed. Cir. 1997).
    Section 256 addresses two types of inventorship er-
    rors—misjoinder and nonjoinder. Stark v. Advanced Mag-
    netics, Inc., 
    119 F.3d 1551
    , 1553 (Fed. Cir. 1997).
    Misjoinder is the error of naming a person as an inventor
    who is not an inventor; nonjoinder is the error of omitting
    an inventor. See 
    id. Through claims
    of misjoinder and non-
    joinder together, § 256 “allows complete substitution of in-
    ventors.” 6 
    Id. at 1556;
    see 
    id. at 1553.
    6   Before the enactment of the Leahy-Smith America
    Invents Act (“AIA”), Pub. L. No. 112–29, 125 Stat. 284
    (2011), the first paragraph of § 256 stated: “Whenever
    through error a person is named in an issued patent as the
    inventor, or through error an inventor is not named in an
    issued patent and such error arose without any deceptive
    intention on his part . . . .” 35 U.S.C. § 256 (2006) (emphasis
    added). We previously interpreted this language and held
    that “the statute allows correction in all misjoinder cases
    featuring an error and in those nonjoinder cases where the
    12           CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    “Conception is the touchstone of inventorship.” Acro-
    med Corp. v. Sofamor Danek Grp., Inc., 
    253 F.3d 1371
    ,
    1379 (Fed. Cir. 2001) (quoting Burroughs Wellcome Co. v.
    Barr Labs., Inc., 
    40 F.3d 1223
    , 1227 (Fed. Cir. 1994)); ac-
    cord Fina 
    Oil, 123 F.3d at 1473
    . As to joint inventorship,
    a joint inventor must contribute to the invention’s concep-
    tion. E.g., Eli Lilly & Co. v. Aradigm Corp., 
    376 F.3d 1352
    ,
    1358–59 (Fed. Cir. 2004); Ethicon, Inc. v. U.S. Surgical
    Corp., 
    135 F.3d 1456
    , 1460–61 (Fed. Cir. 1998); Fina 
    Oil, 123 F.3d at 1473
    (“[T]o be a joint inventor, an individual
    must make a contribution to the conception of the claimed
    invention that is not insignificant in quality, when that
    contribution is measured against the dimension of the full
    invention.”). He or she need not “make the same type or
    amount of contribution” to the invention nor contribute to
    every claim—a contribution to one claim is enough. Ethi-

    (quoting 35 U.S.C. § 116).
    Further, with regard to joint inventorship, there must
    be “some quantum of collaboration.” Kimberly-Clark Corp.
    v. Procter & Gamble Distrib. Co., 
    973 F.2d 911
    , 917 (Fed.
    Cir. 1992) (“[T]here must be some element of joint behav-
    ior, such as collaboration or working under common direc-
    tion, one inventor seeing a relevant report and building
    upon it or hearing another’s suggestion at a meeting.”); see

    We note, however, that sec-
    tion 20(f) of the AIA removed the emphasized language
    from § 256. AIA sec. 20(f)(1)(B), 125 Stat. at 334. The up-
    dated version of § 256 applies to “proceedings commenced
    on or after” September 16, 2012. 
    Id. sec. 20(l),
    125 Stat. at
    335. Plaintiffs filed their complaint on August 9, 2015, and
    therefore the updated version of § 256 applies to this pro-
    ceeding.
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                  13
    having “some open line of communication during or in tem-
    poral proximity to their inventive efforts”).
    Accepting the complaint’s well-pleaded factual allega-
    tions as true and drawing all reasonable inferences in
    Plaintiffs’ favor, we conclude that Plaintiffs’ claims for cor-
    rection of inventorship are plausible. The complaint de-
    scribes Goodyear’s prior failures with inflation technology.
    It also describes two meetings with Goodyear representa-
    tives—both arranged at Goodyear’s initiative and attended
    by Mr. Benedict, Goodyear’s point-person on SIT technol-
    ogy. Goodyear sought technical information from Coda at
    both meetings. And in the second meeting, Mr. Benedict
    requested that he and his team be allowed to spend some
    time alone with Coda’s functional prototype, during which
    he photographed it without permission. After this second
    meeting, Goodyear stopped communicating with Coda for
    a time. When Coda reached out to Mr. Benedict attempting
    to restart communications, Mr. Benedict responded that a
    meeting would be premature.
    Yet the next month, in preparation for Goodyear’s own
    internal meeting, a Goodyear employee independently con-
    tacted Coda to inquire about the status of Coda’s SIT tech-
    nology. Correspondence with that employee revealed that
    Mr. Benedict responded in an “oddly vague” way when
    asked whether Goodyear had looked into Coda’s invention.
    Also that month, Goodyear applied for the first in a series
    of patents covering assemblies and methods concerning
    self-inflating tires, with claims covering the allegedly
    novel, proprietary, and confidential information Coda dis-
    closed to Goodyear. Years later, after Coda deemed the
    Goodyear endeavor a bust, Coda received an unsolicited
    email from the former Goodyear employee, who said that
    Goodyear copied Coda’s SIT technology.
    Construing the complaint in the light most favorable to
    Plaintiffs and taking these and other highly specific facts
    together—including, but not limited to, Goodyear’s prior
    14            CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    failure, its eagerness to meet with Coda, its unauthorized
    photography of Coda’s functional prototype, the timing of
    its distancing itself from Coda and its filing for the ’586 pa-
    tent, and a pointed accusation from one of its former em-
    ployees—we conclude that Plaintiffs’ correction-of-
    inventorship claims are plausible. These facts allow the
    reasonable inference that Mr. Hrabal conceived the inven-
    tion of the ’586 patent and that Messrs. Benedict and Losey
    did not. See 
    Iqbal, 556 U.S. at 678
    (“A claim has facial
    plausibility when the plaintiff pleads factual content that
    allows the court to draw the reasonable inference that the
    defendant is liable for the misconduct alleged.”). They also
    allow the reasonable inference that Mr. Hrabal made a
    more-than-insignificant contribution to the conception of at
    least one claim of each of the Alleged Jointly Invented Pa-
    tents. Cf. Fina 
    Oil, 123 F.3d at 1473
    (“The determination
    of whether a person is a joint inventor is fact specific, and
    no bright-line standard will suffice in every case.”). Fur-
    ther, Coda’s two meetings with Goodyear representatives,
    as well as the parties’ signing a nondisclosure agreement
    going to cooperation between the parties in developing SIT
    technology, allow the reasonable inference that the collab-
    oration requirement was satisfied as to the Alleged Jointly
    Invented Patents.
    The “plausibility standard is not akin to a ‘probability
    requirement.’” 
    Iqbal, 556 U.S. at 678
    (quoting 
    Twombly, 550 U.S. at 556
    ). Rather, Plaintiffs need only “nudge[]
    their claims across the line from conceivable to plausible.”
    See 
    Twombly, 550 U.S. at 570
    . Under these circumstances,
    we conclude that Plaintiffs have done so as to their correc-
    tion-of-inventorship claims.
    The district court’s contrary conclusion rested largely
    on a procedural error—namely, the consideration of mate-
    rial outside the pleadings. The principle is familiar:
    Assessment of the facial sufficiency of the com-
    plaint must ordinarily be undertaken without
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                 15
    resort to matters outside the pleadings. If a court
    does consider material outside the pleadings, the
    motion to dismiss must be treated as a motion for
    summary judgment under Rule 56 and all parties
    must be given a reasonable opportunity to present
    all material pertinent to the motion.
    Gavitt v. Born, 
    835 F.3d 623
    , 640 (6th Cir. 2016) (citation
    omitted); see Fed. R. Civ. P. 12(d) (stating similarly); 5C
    Charles Alan Wright & Arthur R. Miller, Federal Practice
    and Procedure § 1366 (3d ed. 2018) (“Once the district court
    decides to accept matters outside of the pleadings, the pres-
    ence of the word ‘must’ [in Rule 12(d)] indicates that the
    judge must convert the motion to dismiss into one for sum-
    mary judgment . . . . [T]hat is what has been done in a vast
    array of cases, especially when the district court actually
    considers the contents of this material in deciding the mo-
    tion.”).
    The district court considered the Hrabal article without
    converting Defendants’ motion into one for summary judg-
    ment and without giving Plaintiffs a reasonable oppor-
    tunity to present all pertinent material. Defendants spend
    little time defending this procedure. They argue only that
    the district court properly relied on the Hrabal article with-
    out conversion because the article was judicially noticeable
    as a “public-record fact[].” Appellee’s Br. 18. We are un-
    persuaded that the conversion rule was appropriately cir-
    cumvented on this basis.
    Although a district court may consider judicially no-
    ticeable matters outside the pleadings without converting
    a Rule 12(b)(6) motion into one for summary judgment, see
    Jackson v. City of Columbus, 
    194 F.3d 737
    , 745 (6th Cir.
    1999), overruled on other grounds by Swierkiewicz v.
    Sorema N. A., 
    534 U.S. 506
    (2002), judicially noticeable
    facts must “not [be] subject to reasonable dispute,” see Fed.
    R. Evid. 201(b). Here, the district court used the Hrabal
    article to “determine whether it was a 2008 public
    16            CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    disclosure of something Coda now claims was secret when
    disclosed to Goodyear in 2009.” Dismissal Opinion, 
    2016 WL 5463058
    , at *2; see J.A. 24–25 (concluding that the ar-
    ticle publicly disclosed each element of the alleged trade
    secrets). But whether the Hrabal article actually disclosed
    those alleged novel trade secrets was a reasonably (indeed,
    hotly) disputed factual issue—one outside any judicial-no-
    tice exception to the general rule requiring conversion, and
    one that should not have been resolved adversely to Plain-
    tiffs on a motion to dismiss. The district court erred in con-
    sidering the Hrabal article for this purpose without
    converting Defendants’ motion to dismiss into one for sum-
    mary judgment and giving Plaintiffs a reasonable oppor-
    tunity to present all pertinent material. 7
    B
    The district court also erred in dismissing Plaintiffs’
    trade-secret-misappropriation claim as time-barred.
    An Ohio trade-secret-misappropriation claim must be
    brought “within four years after the misappropriation is
    discovered or by the exercise of reasonable diligence should
    have been discovered.” Ohio Rev. Code § 1333.66; Adcor
    Indus., Inc. v. Bevcorp, LLC, 
    411 F. Supp. 2d 778
    , 784–85
    (N.D. Ohio 2005) (observing that this provision incorpo-
    rates the “discovery rule”). Defendants’ motion to dismiss
    argued that if Plaintiffs had been reasonably diligent, they
    7   We note further that, to the extent the district
    court relied on the ’586 patent and Mr. Hrabal’s prior, pub-
    lished patent application to determine that the alleged
    novel trade secrets were already in the prior art, see Dis-
    missal Opinion, 
    2016 WL 5463058
    , at *5, such a determi-
    nation was improper at this stage, for at least the reason
    that it constituted an inference adverse to Plaintiffs when
    there were other reasonable inferences to draw in their fa-
    vor.
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                 17
    would have discovered the alleged trade-secret misappro-
    priation by June 2011, when the application leading to the
    ’586 patent published. J.A. 284–85. Defendants based
    their reasonable-diligence theory on Plaintiffs’ activity in
    the SIT patent space and the purported ease of discovering
    new patents and patent applications “[w]ith today’s tech-
    nology.” J.A. 284. The district court adopted a different
    theory—one to which Plaintiffs never had an opportunity
    to respond. The court found that the facts alleged in the
    complaint, including the independent contact from the
    Goodyear employee in 2009, “should have been sufficient
    notice to plaintiffs that something might have been amiss,”
    thus triggering a duty to investigate. Dismissal Opinion,
    
    2016 WL 5463058
    , at *10 (emphasis in original). The court
    found that such an investigation would have led to the dis-
    covery of the patent application when it published. 
    Id. The statute-of-limitations
    inquiry here is when Plain-
    tiffs discovered or by the exercise of reasonable diligence
    should have discovered their claim. This inquiry is fact-
    specific. See 
    Adcor, 411 F. Supp. 2d at 785
    –86 (citing Ohio
    law). Defendants ask us to infer, from the complaint itself,
    that Plaintiffs should have begun investigating in 2009
    and that, had they done so, they would have discovered the
    application leading to the ’586 patent as of its publication
    date eighteen months later. See Appellee’s Br. 29–30, 33
    (adopting the district court’s theory). Defendants argue
    that the only reasonable inference to be drawn is against
    Plaintiffs. Appellee’s Br. 30 (saying that Plaintiffs’ allega-
    tions “lead inexorably to only one reasonable inference—
    that [Plaintiffs] had constructive notice of potential claims
    in 2009”).
    We disagree. Plaintiffs might have assumed Goodyear
    lost interest in the technology, given its previous failed in-
    vestment. Or they might have thought that Goodyear
    would honor the nondisclosure agreement. See, e.g., Allied
    Erecting & Dismantling 
    Co., 805 F.3d at 707
    (noting that
    18            CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER
    “all reasonable inferences” must be drawn in Plaintiffs’ fa-
    vor in reviewing a motion to dismiss). 8
    Regardless, these issues go more to the merits of De-
    fendants’ statute-of-limitations defense than the com-
    plaint’s sufficiency. Indeed, because “[t]he statute of
    limitations is an affirmative defense, and a plaintiff gener-
    ally need not plead the lack of affirmative defenses to state
    a valid claim,” a Rule 12(b)(6) motion, “which considers
    only the allegations in the complaint, is generally an inap-
    propriate vehicle for dismissing a claim based upon the
    statute of limitations.” Cataldo v. U.S. Steel Corp., 
    676 F.3d 542
    , 547 (6th Cir. 2012) (citation omitted); see Lutz v.
    Chesapeake Appalachia, L.L.C., 
    717 F.3d 459
    , 464 (6th Cir.
    2013).
    Considering only the complaint, and drawing all rea-
    sonable inferences in Plaintiffs’ favor, we conclude that the
    district court erred in dismissing Plaintiffs’ trade-secret-
    misappropriation claim as time-barred.
    II
    We now turn to Plaintiffs’ post-judgment motions. Alt-
    hough the district court found that the proposed amended
    complaint set forth Plaintiffs’ correction-of-inventorship
    claims with “amazing clarity,” it denied Plaintiffs leave to
    8   We also reject, for similar reasons, Defendants’ the-
    ories based on its characterization of Plaintiffs’ activity in
    the SIT patent space and the purported ease of discovering
    new patents and patent applications. Both ask us to infer
    that Plaintiffs were looking for SIT patents (or should have
    been doing so) at a certain time and that they would have
    found the ’586 patent application at the time it was pub-
    lished. But the complaint does not compel those inferences
    to the exclusion of reasonable inferences favorable to Plain-
    tiffs.
    CODA DEVELOPMENT v. GOODYEAR TIRE & RUBBER                19
    amend their complaint. We find this result troubling, par-
    ticularly given the previously described errors.
    Leave to amend should be “freely give[n] . . . when jus-
    tice so requires.” Fed. R. Civ. P. 15(a)(2); see 
    Morse, 290 F.3d at 799
    –800. The Federal Rules of Civil Procedure fa-
    vor resolution of cases on their merits. See Foman v. Davis,
    
    371 U.S. 178
    , 181–82 (1962); see also Krupski v. Costa Cro-
    ciere S. p. A., 
    560 U.S. 538
    , 550 (2010) (observing that Rule
    15 in particular expresses this preference). The Supreme
    Court in Foman indicated that, in the absence of any ap-
    parent reason (e.g., undue delay, bad faith or dilatory mo-
    tive, repeated failure to cure deficiencies by previously
    allowed amendments, undue prejudice to the opposing
    party, futility), leave to amend should be freely given, as
    Rule 15 
    requires. 371 U.S. at 182
    . While the post-judg-
    ment context introduces competing considerations, 
    Morse, 290 F.3d at 800
    , our vacating the district court’s dismissal
    should remove such considerations from the analysis.
    At oral argument, Plaintiffs expressed their desire to
    proceed with their proposed amended complaint even if
    this court were to conclude, as it now has, that the original
    complaint sufficiently stated the claims on appeal. Oral
    Arg. at 7:40–52; see 
    id. at 7:02–40
    (describing how the num-
    ber of claims in the proposed amended complaint has been
    pared down from the original complaint). We deem Plain-
    tiffs’ suggested approach sensible and are aware of no rea-
    son why they should not be permitted to file their proposed
    amended complaint on remand. 9
    9   Aside from a potential futility argument, Defend-
    ants’ counsel did not articulate any argument Defendants
    might have in opposition to the filing of the proposed
    amended complaint under these circumstances. Oral Arg.
    at 29:19–30:12.

    For the foregoing reasons, we vacate the district court’s
