    v. JOSEPH AFERZON ET AL.
    (AC 44098)
    Elgo, Alexander and Sheldon, Js.
    Syllabus
    The plaintiff, M Co., which designs and develops prototypes of medical
    devices, sought to recover damages for breach of contract and unfair
    trade practices from the defendants, A, a neurosurgeon and inventor,
    and I Co., which A and a partner had formed to develop medical devices
    for use in spinal surgery. In November, 2004, L, an owner of M Co., and
    A entered into a written agreement under which the parties were to share
    equally any compensation that resulted from the sale and/or licensing
    of a medical device conceived of by A, or any version thereof, for use
    in spinal surgery. The parties’ one page contract provided that any
    required funding or financial commitments were to be part of a separate
    agreement they would negotiate later and that A was to promptly notify
    M Co. of any compensation he received for the device or any versions
    thereof. A further agreed that he was not under any contractual agree-
    ment with any other company concerning the device. At the time the
    parties entered into the written agreement, they also agreed orally that
    M Co. would create design drawings and a prototype of the device, and,
    at that time, A gave M Co. his initial drawings of the device. By early
    2005, M Co. had prepared a prototype of the device and successfully
    installed it in a cadaver. M Co. thereafter utilized a different design and
    produced another prototype that it gave to A by October, 2005. By that
    time, A had become dissatisfied with M Co.’s work and continued to
    work on developing the device on his own without informing M Co. In
    December, 2005, A applied for a patent on an anterior intervertebral
    spinal fixation and fusion device that he had developed with the help
    of his son. A thereafter did not respond in writing to a letter from L in
    February, 2006, concerning the value of M Co.’s services and, in July,
    2007, formed I Co. A also did not respond to e-mails from L in 2008
    requesting an update on the project, and, in May, 2008, A and his son,
    without informing M Co., assigned to I Co. their ownership interest in
    their pending patent. In 2009, several months before A and his son
    were issued a patent on their device, I Co. entered into a cross license
    agreement with S Co., a medical device manufacturer, that allowed S
    Co. to sell spinal fusion devices that were based on the patented device.
    In exchange, I Co. was to receive shares of A Co.’s stock and, thereafter,
    certain royalty and other payments. Between June, 2010, and August,
    2019, S Co. sent I Co. thirty-four royalty payments, shares of S Co. stock,
    and $50,000 for I Co.’s expenses in developing and patenting the spinal
    fusion device. A and I Co. never notified M Co. of their receipt of
    compensation for the sale and/or licensing of the spinal fusion device.
    After M Co. first became aware that A had developed and patented a
    profitable spinal fusion device, its counsel sent letters to A in November,
    2017, and in February, 2018, requesting that A inform M Co. as to those
    matters. A did not respond to either letter. The defendants asserted
    various special defenses, including that M Co.’s claims were barred by
    applicable statutes of limitations. M Co. asserted that the running of
    the statutes of limitations had been tolled pursuant to the statute (§ 52-
    595) concerning fraudulent concealment and/or the continuing course
    of conduct doctrine. The trial court initially rendered partial judgment for
    M Co. on its breach of contract claim and its claim under the Connecticut
    Unfair Trade Practices Act (CUTPA) (§ 42-110 et seq.). The court deter-
    mined that the November 4, 2004 document, as supplemented by the
    parties’ contemporaneous oral agreement, was sufficient to form a defi-
    nite contract. It further determined that the patented device was a
    version of the device for which M Co. had created design drawings and
    a prototype for A, and that I Co. was founded in bad faith to avoid
    liability to M Co. In awarding damages, the court found that, except for
    S Co.’s $50,000 payment for expenses, M Co. was entitled to recover 50
    percent of the sum of all thirty-four royalty payments I Co. received
    from S Co., including the cash value of the payment of shares of S Co.
    stock, and awarded M Co. damages and prejudgment interest pursuant
    to statute (§ 37-3a) on its breach of contract claim. Additionally, the court
    determined that the running of any applicable statutes of limitations
    had been tolled by both § 52-595 and the continuing course of conduct
    doctrine but did not determine whether the three year statute of limita-
    tions (§ 52-581) or the six year statute of limitations (§ 52-576) applied
    to M Co.’s breach of contract claim. The court limited M Co.’s recovery
    under CUTPA to an award of attorney’s fees and expenses. The court
    also awarded M Co. interest pursuant to statute (§ 52-192a) on an offer
    of compromise M Co. had made that the defendants did not accept. On
    the defendants’ appeal and M Co.’s cross appeal to this court, held:
    1. The trial court’s consideration of parol evidence in determining that the
    parties entered into an enforceable contract was permissible, as the
    November, 2004 agreement was not integrated: the written portion of
    the agreement was clearly not the final repository of the parties’ dealings,
    as it included no obligation on the part of M Co. and, without mentioning
    M Co., merely stated that another agreement would be negotiated later;
    moreover, because the agreement was not integrated as to M Co.’s
    development commitments insofar as it provided that those commit-
    ments would be the subject of the separate agreement, the element of
    the parties’ extrinsic negotiation the court relied on was that M Co.
    orally agreed to create drawings and a prototype, which did not violate
    the parol evidence rule; furthermore, the court’s conclusion that the
    parties had an enforceable contract was premised on its amply supported
    factual finding that M Co.’s obligations were orally agreed to on the
    same date the document was signed, and because that finding was based
    on the court’s credibility findings, the court’s subsequent finding that
    the essential contract terms were agreed to on November 4, 2004, was
    not clearly erroneous.
    2. The trial court properly determined that the patented device and M Co.’s
    prototype, on which it was based, were within the scope of the parties’
    agreement, and, thus, it was not improper for the court to conclude that
    the patented device was a version of the device depicted in A’s initial
    sketches: the defendants could not prevail on their claim that the court
    failed to apply the language in the written agreement in analyzing
    whether the licensed patent was associated with the device in A’s initial
    drawings or a version thereof, as the trial court’s usage of ‘‘relate’’
    reflected its interpretation of the agreement’s operative language, and it
    stated elsewhere in its memorandum of decision that the patent drawings
    appeared to be a ‘‘version’’ of the same device on which A had promised
    to partner with M Co.; moreover, it was not improper, as the defendants
    claimed, for the court to compare A’s 2004 sketches to the figures in
    the patent application and patent to determine if the idea in the patent
    was related to the idea referenced in the parties’ agreement, as nothing
    in the agreement suggested an intention that a claims analysis under
    federal patent law be the method used to determine if a subsequent
    device was a version of the original device, as to which M Co. was
    entitled to receive compensation, and the court did not rely solely on
    the figures in the patent, as it mentioned several times in its decision
    what was described in the patent; furthermore, it was not improper for
    the court to consider M Co.’s prototype in analyzing the language of
    the agreement, as the agreement allowed for such consideration, the
    court considered the prototype to be a link in a chain from A’s initial
    drawings to the design he patented, and the phrase in the agreement,
    ‘‘intellectual property developed associated with this device and/or ver-
    sions of this device,’’ covered intellectual property that was associated
    with versions of the device and permitted the court to consider later
    versions of the initial device.
    3. The trial court improperly concluded that any statute of limitations applica-
    ble to M Co.’s claims was tolled under either § 52-595 or the continuing
    course of conduct doctrine:
    a. Because the statute of limitations could no longer be tolled as a result
    of fraudulent concealment once M Co. had sufficient knowledge of its
    cause of action for breach of contract, the six factual predicates on which
    the trial court relied in making its determination could not constitute
    fraudulent concealment, as A’s letter to L in 2006, L’s e-mails to A and
    A’s transfer of his patent rights to I Co. in 2008, and I Co.’s receipt of
    S Co. stock in 2010 preceded any breach of the parties’ contract, and, thus,
    it was impossible at those times for A to have intentionally concealed
    or to have had actual awareness of M Co.’s then nonexistent cause of
    action, and M Co. had already learned of the facts necessary to establish
    a cause of action for breach of contract at the time its counsel mailed
    the presuit letters to A; moreover, A’s failure to notify M Co. whenever I
    Co. received compensation from the sale and/or licensing of the patented
    device merely constituted nondisclosure, which, standing alone, could
    not establish fraudulent concealment in the absence of a fiduciary duty.
    b. The continuing course of conduct doctrine did not apply to the defen-
    dants’ actions, as A’s series of breaches caused separate damages that
    were readily calculable at the time of each breach, which was incompati-
    ble with the doctrine’s requirement of an initial wrong and a subsequent
    continuing duty that are distinct from one another; moreover, there was
    no evidence to support the court’s finding that the parties had a special
    relationship, as A’s continuing duty to report his gains from the device
    idea to M Co. alone was insufficient to establish a special relationship,
    the court made no findings that the parties had a confidential relationship
    or that there was a unique degree of trust and confidence between
    them, and a mere contractual relationship did not create a fiduciary or
    confidential relationship.
    c. The six year statute of limitations set forth in § 52-576 applied to M
    Co.’s breach of contract claim, as the contract between the parties was
    not executory; although there may have been some dispute at trial as
    to the extent of M Co.’s obligations, neither party challenged the trial
    court’s factual finding that M Co. fully performed its contractual obliga-
    tions.
    d. Because of the viability of the defendants’ special defense under the
    statute of limitations, the trial court’s award of expectation damages on
    M Co.’s breach of contract claim had to be reduced to the total of all
    expectation damages the court awarded on the basis of the defendants’
    failure to pay M Co. its 50 percent share of the compensation the defen-
    dants received for the sale and/or licensing of the patented device within
    the applicable six year limitation period, and, although the court unac-
    countably included 50 percent of S Co.’s $50,000 reimbursement payment
    to I Co. for expenses in the calculation of M Co.’s expectation damages,
    this court did not need to modify the adjusted award of expectation
    damages because the $50,000 payment was received by the defendants
    before the six year limitation period began; moreover, because the trial
    court erroneously awarded prejudgment interest on several sums M Co.
    claimed as expectation damages that were outside the six year limitation
    period and then compounded that error by awarding additional prejudg-
    ment interest on those same sums until the date it rendered final judg-
    ment, the interest on both awards had to be reduced to exclude the
    improperly awarded interest.
    e. The trial court properly found that A breached the parties’ agreement
    in bad faith and that those breaches constituted violations of CUTPA:
    although the court improperly awarded M Co. attorney’s fees and
    expenses on the basis of conduct by the defendants that occurred outside
    of CUTPA’s three year statute of limitations (§ 42-110g), the evidence
    supported the court’s finding that a number of the defendants’ breaches
    of the agreement occurred within the three year limitation period, and,
    because the court engaged in no discussion of the applicable statute of
    limitations, and several breaches on which it relied occurred outside
    the three year limitation period, the case had to be remanded for a
    determination, if possible, of what portion of the fees and costs awarded
    were reasonably incurred to litigate that portion of the CUTPA claim
    that was not barred by § 42-110g.
    4. The trial court erred in determining the amount of offer of compromise
    interest to which M Co. was entitled: the court improperly calculated
    the interest on the basis of the difference between the amount of M
    Co.’s recovery and the amount of its offer of compromise, as § 52-192a
    (c) requires a calculation on that difference only when the offer of
    compromise is filed by a counterclaim plaintiff pursuant to statute (§ 8-
    132), the court failed to include its award of prejudgment interest under
    § 37-3a in M Co.’s total recovery when calculating offer of compromise
    interest, and it improperly calculated the interest at a rate other than
    the statutory rate; accordingly, the judgment on the cross claim awarding
    offer of compromise interest was reversed, and the case was remanded
    for recalculation of the amount of that award.

    Procedural History
    Action to recover damages for, inter alia, breach of
    contract, and for other relief, brought to the Superior
    Court in the judicial district of New Haven and trans-
    ferred to the judicial district of Hartford, Complex Liti-
    gation Docket, where the action was withdrawn in part;
    thereafter, the case was tried to the court, Moukawsher,
    J.; judgment in part for the plaintiff, from which the
    defendants appealed to this court; subsequently, the
    court, Moukawsher, J., granted in part the plaintiff’s
    motion for attorney’s fees; thereafter, the court, Mou-
    kawsher, J., issued an order awarding the plaintiff cer-
    tain interest and rendered judgment for the plaintiff,
    from which the defendants filed an amended appeal
    and the plaintiff filed a cross appeal. Reversed in part;
    judgment directed; further proceedings.

    Opinion
    SHELDON, J. This appeal and cross appeal involve
    a dispute over the defendants’ alleged failure to make
    payments to the plaintiff under a contractual agreement
    between them to share equally all compensation
    resulting from the sale and/or licensing of a medical
    device conceived of by the individual defendant, or any
    version thereof, in exchange for the plaintiff’s creation
    of design drawings and a prototype of the device based
    on the individual defendant’s initial sketches of it. The
    defendants appeal from the judgment of the trial court,
    Moukawsher, J., rendered in favor of the plaintiff on
    its claims of breach of contract and unfair trade prac-
    tices in violation of the Connecticut Unfair Trade Prac-
    tices Act (CUTPA), General Statutes § 42-110a et seq.,
    arising from that dispute. The defendants claim that
    the trial court improperly concluded (1) that the parties
    entered into a definite and enforceable contract to make
    the subject payments in exchange for the plaintiff’s
    work, (2) that payments received by the defendants for
    the sale and/or licensing of an anterior spinal fusion
    device known as the Solus, which was based on a design
    patented by the individual defendant after his alleged
    contract with the plaintiff had been entered into, were
    covered by the contract, (3) that all statutes of limita-
    tions applicable to the plaintiff’s claims for relief in
    this case were tolled under the fraudulent concealment
    doctrine and/or the continuing course of conduct doc-
    trine, and (4) that the plaintiff was entitled to recover
    attorney’s fees from the defendants under CUTPA based
    upon the defendants’ bad faith breaches of the parties’
    alleged contract. The plaintiff cross appeals from the
    trial court’s judgment awarding it offer of compromise
    interest on its judgment against the defendants, arguing
    that the court improperly calculated the amount of such
    interest to which it was entitled. On the defendants’
    appeal, we affirm in part and reverse in part the judg-
    ment of the trial court. On the plaintiff’s cross appeal,
    we reverse the judgment of the trial court and remand
    the case for further proceedings with instructions to
    recalculate the amount of offer of compromise interest
    to which the plaintiff is entitled in accordance with this
    opinion.
    The following procedural history and facts, as found
    by the court and supported by the record, are relevant
    to this case. The plaintiff corporation, Medical Device
    Solutions, LLC (plaintiff or MDS), was formed in 2003,
    by William Lyons in Meriden to engage in the business
    of designing and developing medical device prototypes.
    At the time he formed MDS, Lyons was already the
    partial owner and operator of another company in Meri-
    den called Lyons Tool & Die, which was engaged in the
    business of manufacturing medical components. MDS
    and Lyons Tool & Die were operated in the same physi-
    cal premises, and MDS used Lyons Tool & Die employ-
    ees to manufacture its prototypes. MDS initially had
    one other member, Wayne Young, who remained a 50
    percent owner of the corporation until 2007.
    The individual defendant, Joseph Aferzon, is an
    accomplished neurosurgeon and inventor who has
    owned and operated a private medical practice in Con-
    necticut since 1996. Aferzon frequently partnered with
    Jeffrey A. Bash, an orthopedic spine surgeon, to per-
    form complex spinal surgeries. Bash estimated that he
    and Aferzon had performed approximately 10,000 sur-
    geries together by the time of trial. The defendant corpo-
    ration, International Spinal Innovations, LLC (ISI), was
    formed in 2007 by Aferzon and Bash to develop medical
    devices for use in spinal surgery.
    Aferzon was interested in making spinal fusion sur-
    gery safer and less invasive. In June, 2004, he conceived
    of a small spinal fusion device consisting of a cage and
    rotating blades. The trial court described the concept
    of the device as follows: ‘‘The cage is a sturdy tapering
    rectangle, open, without top or bottom. Within its four
    walls is a series of rotating, claw-like blades. Doctors
    insert this cage between the vertebrae of the spine and
    use a tool to thrust sets of the claws out of the cage’s
    top and bottom. As the claws emerge from their cage,
    they dig themselves into the ends of the vertebrae, fixing
    the cage in place between them. This fuses the bones
    together, and they gradually heal into a single solid
    bone.’’ Aferzon sketched some initial drawings of the
    device and, on September 27, 2004, applied for a provi-
    sional patent on it with the United States Patent and
    Trademark Office (patent office) on the basis of those
    drawings. The patent application titled the device a
    ‘‘CLAWFIX’’ and described it as a ‘‘novel method’’ for
    ‘‘direct intervertebral fixation.’’ Attached to the applica-
    tion were the initial drawings of the device that Aferzon
    had sketched in June, 2004.
    On November 4, 2004, Aferzon approached Lyons and
    Young at MDS to ask for their help in creating the
    device. He provided them with his initial drawings and
    asked them to create a prototype of the device. During
    that visit, MDS gave Aferzon a one page document for
    his signature, which he and Lyons then signed. This
    document set forth an agreement that is central to the
    parties’ dispute. The subject line of the document reads,
    ‘‘Reference invention: Spinal Cage with Rotating/Oppos-
    ingBlades,’’ and its text provides: ‘‘Joseph Aferzon
    (inventor/owner of above stated invention) agrees that
    [MDS] will receive 50% of the total compensation
    resulting from the sale and/or licensing of the above
    mentioned device, versions of this device, associated
    intellectual property and/or any intellectual property
    developed associated with this device and/or versions
    of this device. Any development, funding or financial
    commitments required will be part of a separate agree-
    ment and negotiated at a later date. [Aferzon] further
    agrees to promptly notify [MDS] of any compensation
    received for the above mentioned device, versions of
    the device, associated intellectual property and/or any
    intellectual property developed associated with this
    device and versions of this device. This agreement is
    limited to the above mentioned device, versions of this
    device, associated intellectual property and/or any intel-
    lectual property developed associated with this device
    and/or versions of this device. In signing this agreement,
    [Aferzon] agrees that he has not had prior contact with
    any company regarding this specific device and he is
    not under any contractual agreement with any other
    companies concerning this device.’’
    Although the document provided that ‘‘[a]ny develop-
    ment, funding or financial commitments required will
    be part of a separate agreement and negotiated at a
    later date,’’ the parties agree that no further written
    agreements were ever executed. The court instead
    found, as Lyons and Young both testified, that the par-
    ties agreed orally, on the same day they signed the
    written agreement, that MDS’s obligation under the
    written agreement would be to create drawings and a
    prototype of the new device conceived by Aferzon ‘‘as
    a part [of] an effort to prove the concept’’ of the device.1
    Lyons and Young promptly began to work on produc-
    ing a prototype. Young explained that the creation of
    a medical device prototype proceeds in stages. It begins
    with sketches, moves on to the creation of digital design
    files known as computer aided design (CAD) files, and
    ultimately concludes with the manufacture of a proto-
    type. Lyons testified that, because Aferzon’s drawings
    did not include an adequate mechanism for rotating the
    blades within the cage, he and Young had to come up
    with such a mechanism themselves. Young thus pre-
    pared a series of sketches based on Aferzon’s ideas and
    eventually came up with a ‘‘center shaft design’’ for
    rotating the blades, in which the rotating blades were
    attached to a single shaft that ran through the cage of
    the device. MDS then created multiple digital design
    files for a center shaft device and manufactured a proto-
    type of the device using the center shaft design.
    Lyons and Young further testified that the center
    shaft design prototype was tested in a cadaver at the
    University of Connecticut Health Center in Farmington
    either toward the end of 2004 or in early 2005. They
    also testified that Aferzon and Bash were present during
    the test at the health center when the device was suc-
    cessfully installed in a cadaver using an Allen wrench
    to rotate the blades into place. Although Aferzon and
    Bash both testified that they had no recollection of the
    cadaver test, the court credited the testimony of Lyons
    and Young on this subject.
    After the cadaver test, MDS continued its work on
    the device, pivoting to a different design. Young began
    to work on a ‘‘rack and pinion’’2 design for the device
    that was safer and more versatile than its predecessor,
    as it allowed the blades to be reversed more efficiently
    and prevented them from disengaging. Rather than uti-
    lizing a single central shaft on which all of the blades
    rotated, this second design utilized two geared shafts
    running through the cage, with three blades affixed to
    each of them on geared teeth. Lyons explained that the
    ‘‘blades had slots that had teeth that would mesh with
    the pinions. And, again, when you rotated the pinions,
    that would engage the rack and rotate the blades. . . .
    One [pinion] would rotate the three . . . blades in one
    direction . . . and the other pinion would rotate the
    blades in the opposite direction.’’ From December,
    2004, to May, 2005, MDS prepared and modified several
    digital design files for the device using the rack and
    pinion concept. Eventually, MDS produced a prototype
    of the rack and pinion design, which it gave to Aferzon
    no later than October, 2005. According to Lyons and
    Young, they spent nearly 100 hours working on Afer-
    zon’s idea.
    In the meantime, Aferzon became dissatisfied with
    MDS’s work and continued to work on development of
    the device on his own without informing MDS that he
    was doing so. Aferzon never communicated to MDS
    that he was dissatisfied with their prototype. Aferzon
    began to work on the device with his talented sixteen
    year old son, Joshua Aferzon, who was then taking a
    CAD class in school, on different blade designs and a
    mechanism to rotate the blades within the cage. Ulti-
    mately, on December 22, 2005, three months after the
    provisional patent based on his initial design sketches
    had expired in September, 2005, Aferzon applied for a
    patent on the device he and his son had been working
    on. This application, which was filed in the names of
    Aferzon and his son, described the subject matter of
    the proposed patent as an ‘‘apparatus and method for
    anterior intervertebral spinal fixation and fusion.’’
    On February 26, 2006, Aferzon wrote to Lyons, seek-
    ing to amend his agreement with MDS: ‘‘I respectfully
    request that we amend the agreement dated November
    [4], 2004 . . . . As of the date of this letter there has
    not been sufficient progress on this project to warrant
    the continuation of this agreement. I understand that
    both parties have invested time and resources into this
    project and I am proposing that we determine a fair
    market value for the services that were provided by
    you.’’ Lyons did not respond to this letter in writing, but
    he believed that he spoke with Aferzon about the letter.
    In July, 2007, Aferzon and Bash formed and incorpo-
    rated ISI. The two were equal owners of the company
    and agreed to split any income it generated equally
    between them. On February 27, 2008, and again in May,
    2008, Lyons e-mailed Aferzon to request an update on
    the project. His first e-mail stated: ‘‘It’s been some time
    since the last activity with the cage. Have you aban-
    doned? If so, I would consider a buyout. If not, let’s
    discuss next steps.’’ His second e-mail stated: ‘‘Would
    you consider selling your percentage of the subject
    device? We have not seen any activity and would like
    to continue developing.’’ Aferzon did not respond to
    either e-mail. In the same month that Lyons sent his
    second e-mail, however, on May 9, 2008, Aferzon and his
    son assigned their ownership interest in their pending
    patent application to ISI without informing the plaintiff
    of their actions.
    Because Aferzon and Bash were busy with their medi-
    cal practices, they began to seek a business and engi-
    neering partner to help ISI bring their anterior spinal
    fusion device to market. On May 29, 2009, Aferzon and
    his son received notice that their application for a patent
    on that device, which had been assigned to ISI, had
    been approved by the patent office and would shortly
    issue. Thereafter, on June 19, 2009, ISI entered into
    a cross license agreement with Alphatec Spine, Inc.
    (Alphatec), a medical device manufacturer, which
    allowed Alphatec to develop and sell any medical
    devices that, in the absence of the license agreement,
    would ‘‘infringe a [v]alid [c]laim of the [l]icensed ISI
    [p]atents.’’ In exchange, ISI would receive an initial
    payment of 260,000 shares of Alphatec common stock
    and quarterly minimum royalty payments, a percentage
    of royalty payments over the minimum, and certain
    milestone payments triggered by aggregate sales fig-
    ures. This was the only license agreement between ISI
    and Alphatec. On September 29, 2009, the patent office
    issued patent number 7,594,932 on an ‘‘apparatus for
    anterior intervertebral spinal fixation and fusion,’’ list-
    ing Aferzon and his son as its inventors and ISI as their
    assignee.
    After the patent was cross licensed to Alphatec, Afer-
    zon and Bash worked with Alphatec to develop a spinal
    fusion device based on the patented design with the
    trade name ‘‘Solus,’’ which Alphatec began marketing
    in 2011. Pursuant to the royalty schedule in the cross
    license agreement, Alphatec sent ISI a series of thirty-
    four distinct royalty payments between June, 2010, and
    August, 2019, including the initial payment in shares
    of Alphatec common stock. In addition to the royalty
    payments, Alphatec also sent ISI a payment of $50,000
    that was intended to reimburse it for expenses it had
    incurred in developing and patenting the anterior spinal
    fusion device. These payments, including the cash value
    of the initial payment in Alphatec common stock and the
    expense reimbursement payment, totaled $3,274,578.3
    The defendants never notified the plaintiff that they
    had received any compensation for the sale and/or
    licensing of their anterior spinal fusion device.
    In late summer or early fall of 2017, the plaintiff
    eventually became aware that Aferzon had developed
    a spinal fusion device that had been patented, assigned,
    marketed and become profitable, when Lyons visited
    his physical therapist in Middletown, whose practice
    was adjacent to Bash’s office. The physical therapist
    told Lyons during that visit that Bash had been traveling
    and teaching surgeons how to use a successful medical
    device. Lyons knew that Aferzon and Bash had worked
    together previously on the original spinal fusion device
    that was the subject of Aferzon’s agreement with MDS.
    Notice of Bash’s involvement in teaching the use of a
    similar device prompted the plaintiff to retain counsel.
    The plaintiff’s counsel sent letters to Aferzon on Novem-
    ber 24, 2017, and February 6, 2018, requesting that Afer-
    zon inform the plaintiff if he had sold or licensed the
    device on which MDS had been working, whether he
    had received any compensation for the device, and if
    he owned any intellectual property associated with the
    device. Aferzon did not respond to either letter.
    The plaintiff commenced this action on July 16, 2018,
    and filed its initial complaint in the Superior Court on
    July 19, 2018. Thereafter, in its operative substitute com-
    plaint dated March 6, 2019, the plaintiff asserted claims
    against the defendants of breach of contract and unfair
    trade practices in violation of CUTPA. The defendants
    filed their answer and special defenses to the operative
    complaint on April 5, 2019, denying the plaintiff’s mate-
    rial allegations against them and asserting various spe-
    cial defenses, including that the plaintiff’s claims were
    barred by applicable statutes of limitations.4 Ultimately,
    on October 22, 2019, the plaintiff replied to the defen-
    dants’ special defenses by denying them and pleading,
    in avoidance of the defendants’ statutes of limitations
    defenses, that neither of its claims was barred by an
    applicable statute of limitations because the running of
    all statutes of limitations had been tolled under the
    fraudulent concealment doctrine and/or the continuing
    course of conduct doctrine.
    In the meantime, on June 13, 2019, the plaintiff filed
    an application for a prejudgment remedy. The court
    held an initial evidentiary hearing on the application
    for a prejudgment remedy on September 18, 2019.
    Thereafter, however, on November 12, 2019, the parties
    agreed to convert the prejudgment remedy hearing into
    a full bench trial on the merits of the parties’ claims
    and special defenses, and thus to continue with the
    presentation of evidence. The trial took place over the
    course of seven days, including the initial day of evi-
    dence at the prejudgment remedy hearing, and ended
    with the presentation of closing arguments on March
    6, 2020.
    The court issued its memorandum of decision on
    April 22, 2020, rendering partial judgment for the plain-
    tiff on both of its claims. On the plaintiff’s breach of
    contract claim, the court awarded $1,587,289 in expec-
    tation damages and $475,813.80 in statutory prejudg-
    ment interest through May 4, 2020, pursuant to General
    Statutes § 37-3a. On the plaintiff’s CUTPA claim, the court
    declined to award either punitive damages or additional
    expectation damages but ruled that the plaintiff was
    nonetheless entitled to recover its attorney’s fees in an
    amount to be determined at a later date.
    In reaching its decision, the court first considered
    whether the parties had entered into an enforceable
    contract. The court concluded that the agreement
    embodied in the document signed by Lyons and Aferzon
    on November 4, 2004, as supplemented by their contem-
    poraneous oral agreement as to the plaintiff’s obliga-
    tions under the agreement, was sufficiently definite to
    form a binding contract between them, as there was
    nothing conditional in that agreement, so supplemented.
    After confirming the existence of a contract, the court
    considered whether the patented anterior spinal fusion
    device that the defendants cross licensed to Alphatec
    was a ‘‘version’’ of the device that MDS had worked on
    pursuant to the November 4, 2004 agreement, in which
    case MDS would be entitled to receive 50 percent of all
    compensation resulting from the sale and/or licensing
    of the patented device. The defendants made three argu-
    ments on this issue: (1) that the patented device was
    not a version of the device that MDS had worked on
    pursuant to the parties’ compensation-sharing agree-
    ment of November 4, 2004, (2) that the compensation so
    generated was paid to ISI, not to Aferzon, so it was not
    subject to sharing with the plaintiff under the November
    4, 2004 agreement, and (3) that substantial expenses
    incurred by the defendants to develop the patented
    device significantly reduced the profits generated by
    the sale and/or licensing of that device.5 The court first
    found that the patented device was a version of the
    device for which MDS had created design drawings and
    a prototype for Aferzon. As to the second argument,
    the court found that ISI was founded as part of an
    ‘‘intentional plan to try to avoid liability to MDS in bad
    faith,’’ and thus that ISI was liable to MDS under the
    doctrine of successor liability. Finally, the court found
    that, although the defendants’ account of the expenses
    they had incurred for development of the patented
    device generally was not credible, they credibly estab-
    lished that the initial $50,000 payment that ISI received
    from Alphatec on October 1, 2009, was not compensa-
    tion resulting from the sale and/or licensing of the pat-
    ented device but a reimbursement for development
    expenses that they had incurred to obtain the patent
    for that device.6 The court thus ruled that the plaintiff
    was not entitled to recover 50 percent of that $50,000
    reimbursement payment as damages for breach of the
    agreement. Accordingly, the court ruled that the plain-
    tiff was entitled to recover 50 percent of all payments
    that ISI had received from Alphatec except for the
    $50,000 reimbursement payment.
    The court next considered whether the plaintiff’s
    claims were barred by applicable statutes of limita-
    tions.7 Because the defendants had received compensa-
    tion from Alphatec resulting from the sale and/or licens-
    ing of the patented device from 2010 to 2019, but the
    plaintiff did not learn that it had a valid cause of action
    against the defendants for their failure to share such
    compensation with it until 2017, the statute of limita-
    tions could have had a significant impact on the plain-
    tiff’s recovery in this case. Concluding, however, that
    the running of any applicable statute of limitations had
    been tolled by both the fraudulent concealment doc-
    trine and the continuing course of conduct doctrine,
    the court rejected the defendants’ statute of limitations
    defense to the plaintiff’s breach of contract claim with-
    out determining whether the three year or six year
    statute of limitations for contract actions applied to
    that claim. Accordingly, it concluded that the plaintiff
    was entitled to recover 50 percent of all thirty-four
    royalty payments that ISI had received from Alphatec
    from 2010 through 2019, including the initial payment
    in shares of Alphatec stock.
    The court thus awarded the plaintiff $1,587,289 in
    expectation damages on its breach of contract claim
    plus $475,813.80 in prejudgment interest pursuant to
    § 37-3a, calculated for each unshared royalty payment
    at the rate of 4.5 percent per year on the plaintiff’s
    50 percent share of that payment, from the date the
    defendants received the unshared payment until May
    4, 2020.8
    The plaintiff also made claims for expectation dam-
    ages, punitive damages, and attorney’s fees and expenses
    under CUTPA. Although the court found that the defen-
    dants’ repeated breaches of their contract with the
    plaintiff had been committed in bad faith, and thus
    constituted unfair trade practices in violation of
    CUTPA, it declined to award the plaintiff either punitive
    damages or additional expectation damages on the
    basis of such violations. Instead, it limited the plaintiff’s
    right of recovery under CUTPA to the attorney’s fees
    and expenses it reasonably incurred in prosecuting
    those claims, as authorized by General Statutes § 42-
    110g, in an amount to be determined at a later time.9
    On September 15, 2020, the court awarded the plaintiff
    $756,000 in attorney’s fees and expenses. Finally, on
    September 21, 2020, the court rendered final judgment
    for the plaintiff after extending the end date for the
    calculation of prejudgment interest to that date, and
    recalculating the total amount of such prejudgment
    interest as $504,054. The court also determined that the
    plaintiff was entitled to recover postjudgment interest
    but reserved decision as to the amount of such interest
    until a later time.
    Additionally, on October 10, 2019, before the parties
    agreed to convert the prejudgment remedy hearing into
    a full scale bench trial on the merits of their claims and
    special defenses, the plaintiff filed a unified offer of
    compromise pursuant to General Statutes § 52-192a,
    offering to settle its claims against the defendants for
    $1,150,000. The defendants did not accept the offer.
    Accordingly, the court awarded the plaintiff offer of
    compromise interest of $90,968, a much lesser amount
    than the plaintiff claims it was statutorily entitled to in
    this case. The plaintiff has cross appealed from the
    court’s judgment challenging the amount of the court’s
    offer of compromise interest award. In the end, the
    court rendered final judgment for the plaintiff in the
    total amount of $2,938,311.
    This appeal followed. Additional facts will be set forth
    as necessary.
    I
    THE DEFENDANTS’ APPEAL
    A
    We first address the court’s conclusion that the par-
    ties had an enforceable contract. The defendants argue
    that the written agreement signed by the parties was
    indefinite and that the court improperly used parol evi-
    dence to supplement its essential terms to form a con-
    tract. The plaintiff argues that the parol evidence rule
    does not apply to the written portion of the parties’
    agreement standing alone, and thus that it was not
    improper for the court to consider extrinsic oral evi-
    dence in interpreting it. We agree with the plaintiff.
    As a preliminary matter, we set forth our standard
    of review. ‘‘The existence of a contract is a question of
    fact to be determined by the trier on the basis of all of
    the evidence. . . . To the extent that the trial court has
    made findings of fact, our review is limited to deciding
    whether such findings were clearly erroneous. . . . A
    finding of fact is clearly erroneous when there is no
    evidence in the record to support it . . . or when
    although there is evidence to support it, the reviewing
    court on the entire evidence is left with the definite
    and firm conviction that a mistake has been committed.
    . . . In making this determination, every reasonable
    presumption must be given in favor of the trial court’s
    ruling.’’ (Internal quotation marks omitted.) Tsionis v.
    Martens, 
    116 Conn. App. 568
    , 576, 
    976 A.2d 53
     (2009).
    The following additional facts and procedural history
    are relevant to this issue. The court found that part of
    the contract between the parties was in writing and
    part of it was oral. The only part that was written was
    encapsulated in the document signed on November 4,
    2004, which provided, in part, that ‘‘[a]ny development,
    funding or financial commitments required will be part
    of a separate agreement and negotiated at a later date.’’
    In light of the previously quoted language, the defen-
    dants argued before the court that the parties ‘‘merely
    agreed to make a contract at some future date and that
    there was nothing definite enough between them to
    call a contract, especially because there was only an
    agreement to agree later about financial commitments.’’
    The court first rejected the defendants’ argument that
    the document was only an ‘‘agreement to agree,’’ finding
    that there was nothing conditional in the language of
    the agreement. The court next found that the essential
    terms of the agreement, that the plaintiff would create
    drawings and a prototype of the device and the defen-
    dants would pay the plaintiff 50 percent of the total
    compensation resulting from the sale and/or licensing
    of the device, were in fact agreed to on November
    4, 2004, although the agreement as to the plaintiff’s
    obligations was developed orally. There was substantial
    dispute over what the plaintiff’s obligations were under
    the agreement, but the court credited the testimony of
    Lyons and Young over that of Aferzon. Thus, the court
    relied both on the writing signed by Lyons and Aferzon,
    and on the contemporaneous oral agreement between
    the parties as described by Lyons and Young as the
    basis for finding that the parties had formed a binding
    contract for MDS to build a prototype of Aferzon’s
    device in exchange for 50 percent of all compensation
    received by Aferzon for the sale and/or licensing of that
    device or any version thereof. The court held that ‘‘the
    failure to provide specific terms about future financial
    commitments wasn’t an essential term whose absence
    defeats the very existence of a contract for lack of
    definiteness.’’
    1
    We begin with the defendants’ claim that the court
    improperly considered parol evidence in determining
    whether, and on what terms, the parties reached a defi-
    nite, enforceable contractual agreement. The plaintiff
    argues that, because the agreement was not integrated,
    the parol evidence rule did not apply. We agree with
    the plaintiff.
    ‘‘Because the parol evidence rule is not an exclusion-
    ary rule of evidence . . . but a rule of substantive con-
    tract law . . . the defendants’ claim involves a ques-
    tion of law to which we afford plenary review.’’ (Internal
    quotation marks omitted.) Colliers, Dow & Condon, Inc.
    v. Schwartz, 
    77 Conn. App. 462
    , 466, 
    823 A.2d 438
     (2003).
    ‘‘The parol evidence rule is premised upon the idea
    that when the parties have deliberately put their engage-
    ments into writing, in such terms as import a legal
    obligation, without any uncertainty as to the object or
    extent of such engagement, it is conclusively presumed,
    that the whole engagement of the parties, and the extent
    and manner of their understanding, was reduced to
    writing. After this, to permit oral testimony, or prior or
    contemporaneous conversation, or circumstances, or
    usages [etc.], in order to learn what was intended, or
    to contradict what is written, would be dangerous and
    unjust in the extreme. . . . The parol evidence rule
    does not of itself, therefore, forbid the presentation of
    parol evidence, that is, evidence outside the four cor-
    ners of the contract concerning matters governed by
    an integrated contract, but forbids only the use of such
    evidence to vary or contradict the terms of such a con-
    tract.’’ (Internal quotation marks omitted.) Ravenswood

    105 Conn. App. 7
    , 14–15, 
    936 A.2d 679
     (2007).
    ‘‘Parol evidence offered solely to vary or contradict
    the written terms of an integrated contract is, therefore,
    legally irrelevant. When offered for that purpose, it is
    inadmissible not because it is parol evidence, but
    because it is irrelevant. By implication, such evidence
    may still be admissible if relevant (1) to explain an
    ambiguity appearing in the instrument; (2) to prove a
    collateral oral agreement which does not vary the terms
    of the writing; (3) to add a missing term in a writing
    which indicates on its face that it does not set forth
    the complete agreement; or (4) to show mistake or
    fraud. . . . These recognized exceptions are, of
    course, only examples of situations [in which] the evi-
    dence (1) does not vary or contradict the contract’s
    terms, or (2) may be considered because the contract
    has been shown not to be integrated; or (3) tends to
    show that the contract should be defeated or altered
    on the equitable ground that relief can be had against
    any deed or contract in writing founded in mistake or
    fraud.’’ (Internal quotation marks omitted.) Schilberg

    , 277–78, 
    819 A.2d 773
     (2003).
    We first note that the court did not provide a justifica-
    tion for its consideration of extrinsic oral evidence
    because the defendants did not explicitly raise the parol
    evidence rule at trial, instead arguing primarily that the
    agreement was not binding in the first place. This does
    not preclude us from reviewing the issue. See Heaven
    v. Timber Hill, LLC, 
    96 Conn. App. 294
    , 308, 
    900 A.2d 560

    the introduction of evidence that varies or contradicts
    an exclusive written agreement whether or not there
    is an objection’’ (internal quotation marks omitted)).
    It was permissible for the court to look to extrinsic
    evidence because the November 4, 2004 agreement was
    not integrated. ‘‘In order for the bar against the introduc-
    tion of extrinsic evidence to apply, the writing at issue
    must be integrated, that is, it must have been intended
    by the parties to contain the whole agreement . . . .’’

    they mutually consent to a certain writing or writings
    as the final statement of the agreement or contract
    between them. . . . Only when an integrated contract
    exists and its meaning differs from extrinsic evidence
    offered by one of the parties does the parol evidence
    rule come into play.’’ (Footnotes omitted.)).
    ‘‘Whether the written contract was actually the final
    repository of the oral agreements and dealings between
    the parties depends on their intention, evidence as to
    which is sought in the conduct and language of the
    parties and the surrounding circumstances. If the evi-
    dence leads to the conclusion that the parties intended
    the written contracts to contain the whole agreement,
    evidence of oral agreements is excluded, that is,
    excluded from consideration in the determination of
    the rights and obligations of the litigants, even though
    it is admitted on the issue of their intention. . . . A
    written agreement is integrated and operates to exclude
    evidence of the alleged extrinsic negotiation if the sub-
    ject matter of the latter is mentioned, covered or dealt
    with in the writing . . . if it is not, then probably the
    writing was not intended to embody that element . . . .
    If the evidence, however, does not indicate that the
    writing is intended as an integration, i.e., a final expres-
    sion of one or more terms of an agreement . . . then
    the agreement is said to be unintegrated, and the parol
    evidence rule does not apply.’’ (Citations omitted; inter-
    nal quotation marks omitted.) Associated Catalog Mer-

    210 Conn. 734
    , 739–40,
    
    557 A.2d 525
     (1989).
    The written portion of the November 4, 2004 agree-
    ment, which includes no obligation on the part of the
    plaintiff and explicitly states that another agreement
    will be negotiated, is clearly not a final repository of
    the parties’ dealings. The agreement itself demonstrates
    that the parties did not intend for it to ‘‘completely
    embody the contract between the parties.’’ 11 R. Lord,
    supra, § 33:15. The defendants argue that integration
    must be assessed on an issue-by-issue basis and that
    the agreement was ‘‘integrated with respect to the issue
    of [the plaintiff’s] development commitments insofar
    as it provides that those commitments would be the
    subject of a separate agreement to be negotiated at a
    later date.’’ The defendants rely on language from Cohn
    v. Dunn, 
    111 Conn. 342
    , 
    149 A. 851
     (1930), stating that,
    if a ‘‘particular element of the alleged extrinsic negotia-
    tion’’ is ‘‘mentioned, covered, or dealt with in the writ-
    ing, then presumably the writing was meant to represent
    all of the transactions on that element . . . .’’ (Internal
    quotation marks omitted.) 
    Id., 347
    ; see also Associated
    Catalog Merchandisers, Inc. v. Chagnon, supra, 
    210 Conn. 740
    . But, in the present case, the ‘‘particular ele-
    ment of the alleged extrinsic negotiation’’ that the court
    relied on was that the plaintiff ‘‘was to create drawings
    and a prototype as a part [of] an effort to prove the
    concept . . . .’’ Again, the agreement states that ‘‘[a]ny
    development, funding or financial commitments required
    will be part of a separate agreement and negotiated at
    a later date.’’ It cannot be said that the agreement was
    integrated as to the plaintiff’s obligations when the sen-
    tence in question does not mention the plaintiff but
    merely that any development commitments will be
    negotiated at a later date.
    The defendants also argue that the extrinsic evidence
    indicating that on the same day that the parties signed
    the written agreement they orally decided what the
    plaintiff’s obligation would be thereunder varies from or
    contradicts the provision stating that such an agreement
    would be negotiated at a later date, and thus violates
    the parol evidence rule. That prohibition, however, only
    applies if the document is integrated. See Weiss v.
    Smulders, 
    313 Conn. 227
    , 249, 
    96 A.3d 1175
     (2014)
    (explaining that parol evidence rule forbids only use of
    evidence outside four corners of integrated contract
    ‘‘ ‘to vary or contradict the terms of such a contract’ ’’).
    Because the document was not integrated, the court did
    not err in considering extrinsic evidence to determine
    whether there was a contract and, if so, what the parties’
    obligations were agreed to be thereunder.
    2
    Having concluded that it was not improper for the
    court to consider extrinsic oral evidence when
    determining if the parties entered into an enforceable
    contract, we next consider the correctness of the court’s
    substantive conclusion that the parties’ written agree-

    ate that our review is limited to deciding whether the
    court’s findings of fact were clearly erroneous. See, e.g.,
    Tsionis v. Martens, 
    supra, 576
    .
    The defendants argue that the November 4, 2004
    agreement was ‘‘indefinite on its face’’ as to an essential
    term, the plaintiff’s obligations, and that the document
    was never finalized into an enforceable agreement. We
    have already concluded, however, that it was permissi-
    ble for the court to look beyond the face of the docu-
    ment when making this determination, and the court’s
    conclusion that the parties had a contract was premised
    on a factual finding that the plaintiff’s obligations were
    orally agreed to on the same date that the document
    was signed. There is ample support in the record for
    this factual finding in the testimony of Lyons. The extent
    to which the parties agreed on the plaintiff’s obligation
    was disputed at trial, but the court’s factual finding that
    there was an agreement between them was based on
    a determination that the plaintiff’s version of events
    was more credible than the defendants’ version. ‘‘It is
    well established that [t]his court will not revisit credibil-
    ity determinations. . . . The court was entitled, in its
    role as sole arbiter of credibility to discredit the [defen-
    dants’ testimony].’’ (Citation omitted; internal quotation

    109 Conn. App. 99
    ,
    108–109,

     (2008). Thus, in light of the court’s
    credibility findings, we cannot conclude that the court’s
    subsequent finding that the essential contract terms
    were agreed to on November 4, 2004, was clearly errone-
    ous. The court appropriately concluded that the parties
    had an enforceable contract.

    We next address the court’s conclusion that the pat-
    ented device was a version of the device depicted in
    Aferzon’s initial design sketches, thus entitling the
    plaintiff to 50 percent of all compensation resulting
    from the sale and/or licensing of that device. The defen-
    dants argue that the court misinterpreted the contract
    by disregarding important contractual language in it
    and failing to conduct an appropriate analysis under
    federal patent law. The plaintiff argues, in response,
    that the court properly analyzed the contractual lan-
    guage and that no analysis under federal patent law
    was necessary. We agree with the plaintiff.
    We begin by setting forth the standard of review and
    legal principles relevant to this claim. ‘‘The standard
    of review for the interpretation of a contract is well
    established. Although ordinarily the question of con-
    tract interpretation, being a question of the parties’
    intent, is a question of fact [subject to the clearly errone-
    ous standard of review] . . . [when] there is definitive
    contract language, the determination of what the parties
    intended by their . . . commitments is a question of
    law [over which our review is plenary].’’ (Internal quota-

    The defendants do not challenge any of the court’s
    factual findings on this matter or the court’s ultimate
    determination that the defendants breached that agree-
    ment, which would be reviewed for clear error. See,

     (2004). Instead, the defendants challenge only
    the manner in which the court interpreted the con-
    tract.10 In light of the fact that the defendants’ claim
    is largely directed at the court’s interpretation of the
    agreement, as opposed to the court’s factual findings,
    ‘‘our review is plenary and we must decide whether its

    The following additional facts and procedural history
    are relevant to this issue. We repeat that the written
    portion of the parties’ November 4, 2004 agreement, as
    signed by Lyons and Aferzon, provided: ‘‘Joseph Afer-
    zon (inventor/owner of above stated invention) agrees
    that [MDS] will receive 50% of the total compensation
    resulting from the sale and/or licensing of the above
    mentioned device, versions of this device, associated
    intellectual property and/or any intellectual property
    developed associated with this device and/or versions
    of this device. . . . This agreement is limited to the
    above mentioned device, versions of this device, associ-
    ated intellectual property and/or any intellectual prop-
    erty developed associated with this device and/or ver-
    sions of this device.’’ The defendants argued before
    the court that the patented device, whose sale and/or
    licensing generated all compensation that the plaintiff
    claims a contractual right to share, was not covered by
    the parties’ agreement.11
    The court made the following factual findings before
    reaching its ultimate conclusion that the patented
    device was covered by the agreement: ‘‘Like the [plain-
    tiff’s] prototype, the patent applied for was for an ante-
    rior intervertebral spinal fixation and fusion apparatus.
    The versions illustrated in the patent have a cage and
    preloaded, oppositely rotating blades that the court is
    convinced began with Aferzon’s crude sketch and then
    bear the mark of [the plaintiff’s] work on the nature of
    the cage, the shape of the blade and . . . the preloading
    of those blades into the cage in substitution for Afer-
    zon’s original idea of adding them to the cage later.
    There are differences between the prototype and what
    appears in the patent application—principally a square
    actuating nut that Aferzon makes much of and may
    [accurately] be [attributed] to his son—but [the court]
    cannot pretend after seeing the patent drawings that
    what appears in them is not—as the contract says—a
    ‘version’ of the same device Aferzon promised to part-
    ner with [the plaintiff] on.’’
    In reaching the conclusion that the patented device
    was a version of the device covered by the agreement,
    the court interpreted the agreement in three important
    ways. First, the court concluded that the agreement was
    ‘‘intentionally broad,’’ and thus that it covered ‘‘related’’
    devices and ‘‘the associated intellectual property with
    any ‘related’ device.’’ The court then significantly based
    its analysis on whether the patented device was
    ‘‘related’’ to the device contemplated in the agreement.
    Second, the court compared Aferzon’s initial design
    sketches to the drawings and figures in the patent appli-
    cation. Third, the court compared the plaintiff’s proto-
    type to the drawings and figures in the patent applica-
    tion. Ultimately, the court concluded: ‘‘[T]his matter
    all started with a crude sketch from Aferzon. Without
    charge, [the plaintiff] turned that crude sketch into
    drawings and a prototype that was tested on a cadaver.
    That device was unquestionably an anterior interverte-
    bral spinal fixation and fusion apparatus. Before any
    other prototype was created, Aferzon described in a
    patent application an anterior intervertebral spinal fixa-
    tion and fusion apparatus that included a cage and
    blades sufficiently similar to what [the plaintiff] worked
    on for the court to find the device described in the
    patent to be ‘related’ to the device [the plaintiff] drew
    and prototyped. . . . All we have to do to see the rela-
    tionship is to look at the drawings beginning with Afer-
    zon’s and ending with those in the patent application
    to see that they are at a minimum the same basic idea—
    a sturdy cage with oppositely rotating sets of blades to
    be inserted between the vertebrae. From that, you can
    see that they are at least ‘related.’ ‘Related’ only means
    having a ‘relation’ which itself means having ‘an aspect
    or quality (such as a resemblance) that connects two
    or more things or parts as being or belonging or working
    together or as being of the same kind.’ The MDS proto-
    type and the device described in the patent are ‘of the
    same kind.’ . . . They are ‘related’ for purposes of the
    agreement. And from this patent is a direct path to the
    money.’’ (Footnote omitted.)
    We now turn to the defendants’ arguments on appeal.
    The defendants first claim that the court erred by ana-
    lyzing whether the patented device was ‘‘related’’ to the
    device contemplated in the agreement, arguing that the
    court ‘‘inserted that term into the contract’’ and ‘‘plainly
    failed to apply the actual language used by the parties
    in its decision.’’ The defendants argue that the court
    instead should have strictly analyzed whether the
    licensed patent was ‘‘intellectual property associated
    with’’ the device in Aferzon’s initial drawings or a ‘‘ver-
    sion thereof.’’ (Emphasis added; internal quotation
    marks omitted.) The defendants are correct that the
    written portion of the agreement does not contain the
    word ‘‘related,’’ but, although the court’s memorandum
    of decision does not explicitly say so, we infer that the
    court’s usage of that word reflects the court’s interpreta-
    tion of the agreement’s operative language. We will not
    presume that the court misread the contract, particu-
    larly when the court elsewhere used the language of
    the contract in stating that ‘‘[the court] cannot pretend
    after seeing the patent drawings that what appears in
    them is not—as the contract says—a ‘version’ of the
    same device Aferzon promised to partner with [the
    plaintiff] on.’’ (Emphasis added.)
    The court’s usage of ‘‘related’’ in interpreting the con-
    tract was not improper for two reasons. First, the defen-
    dants make much of the dictionary definitions of ‘‘asso-
    ciated’’ and ‘‘related,’’ which the court cited, arguing
    that the supposedly broader definition of ‘‘related’’
    tainted the analysis. ‘‘We often consult dictionaries in
    interpreting contracts . . . to determine whether the
    ordinary meanings of the words used therein are plain
    and unambiguous, or conversely, have varying defini-
    tions in common parlance.’’ (Internal quotation marks
    omitted.) Nation-Bailey v. Bailey, 
    316 Conn. 182
    , 193,
    
    112 A.3d 144
     (2015). The online version of the Merriam-
    Webster Dictionary that the defendants cite, however,
    also defines ‘‘associated’’ as ‘‘related, connected, or
    combined together.’’ (Emphasis added.) Merriam-Web-
    ster Dictionary, available at https://www.merriam-web-
    ster.com/dictionary/associated (last visited September
    17, 2021). The print version of Merriam-Webster’s Colle-
    giate Dictionary defines ‘‘associated’’12 as ‘‘to join or
    connect together,’’ ‘‘to bring together or into relation-
    ship in any of various intangible ways’’; (emphasis
    added) Merriam-Webster’s Collegiate Dictionary (11th
    Ed. 2014) p. 75; and ‘‘related’’ as ‘‘connected by reason
    of an established or discoverable relation.’’ Id., p. 1050.
    Random House Webster’s Unabridged Dictionary pro-
    vides similar definitions, defining ‘‘associate’’ as ‘‘to
    connect or bring into relation’’; (emphasis added) Ran-
    dom House Webster’s Unabridged Dictionary (2d Ed.
    2001) p. 126; and ‘‘related’’ as ‘‘associated; connected.’’
    Id., p. 1626. We are not convinced that the ‘‘common,
    natural, and ordinary meaning and usage’’ of ‘‘related’’
    is significantly broader than ‘‘associated,’’ as the defen-
    dants contend. See HLO Land Ownership Associates
    Ltd. Partnership v. Hartford, supra, 
    248 Conn. 357
    .
    Second, even if the definition of ‘‘related’’ is broader
    than the definition of ‘‘associated,’’ the interpretation
    of this contract is not as simple as defining the word
    ‘‘associated’’ and asking whether the two devices are
    ‘‘associated’’ with one another. The sentence in question
    is clearly broader than that, covering ‘‘versions of this
    device’’ and ‘‘any intellectual property developed asso-
    ciated with this device and/or versions of this device.’’
    The upshot of this wording is that the agreement can
    cover versions of the device or intellectual property,
    subsequently developed, that is associated with ver-
    sions of the original device, not just directly associated
    with the original device. The court’s usage of ‘‘related’’
    results from a proper interpretation of this clause,
    which the court accurately described as ‘‘intention-
    ally broad.’’
    The defendants next claim that the court improperly
    relied on the drawings and figures contained in the
    defendants’ patent. Specifically, the defendants argue
    that it was improper for the court to determine if the
    idea in the patent was ‘‘related’’ to the idea referenced
    in the parties’ agreement by comparing Aferzon’s 2004
    sketches to the figures in the patent application and
    the subsequent patent. Instead, the defendants argue,
    the court should have looked to the ‘‘claims’’ in the
    patent, which is the well established standard by which
    claims of patent infringement are analyzed.13 They thus
    argue that ‘‘the trial court’s analysis in this respect is
    legally erroneous because the intellectual property that
    ISI licensed to Alphatec is not measured by the patent’s
    drawings, but by its claims.’’ (Emphasis in original.) The
    defendants are correct that the extent of the intellectual
    property licensed to Alphatec would be measured by
    the patent’s claims,14 but ‘‘a contract must be construed
    to effectuate the intent of the contracting parties.’’
    (Internal quotation marks omitted.) HLO Land Owner-
    ship Associates Ltd. Partnership v. Hartford, supra,
    
    248 Conn. 356
    . There is nothing in the parties’ agreement
    that suggests that they intended that a claims analysis
    be the method used to determine if a subsequent device
    was a version of the original device as to which the
    plaintiff was entitled to receive 50 percent of the total
    compensation resulting from its sale and/or licensing.
    Additionally, the scope of the patented invention and
    its subsequent license to Alphatec is simply not relevant
    to the analysis of whether the device is covered by the
    contract. This was the only patent that ISI ever licensed
    to Alphatec, and there is no question that the license
    generated compensation. The determinative question is
    whether the device that was patented and licensed is
    a version of the 2004 device or is intellectual property
    that was developed and associated with a version of
    the device. The scope of the patent has no bearing on
    that question. The defendants can cite to no authority,
    nor have we identified any, that suggests that a state
    court must resolve a contractual dispute over patent
    license profits by looking to federal patent law or a
    claims analysis. Lastly, we note that the court did not
    rely solely upon the figures in the patent, for it men-
    tioned several times what was ‘‘described’’ in the patent.
    Accordingly, it was not improper for the court to deter-
    mine if the devices were related by looking at the figures
    in the patent.
    Finally, the defendants argue that the court erred by
    comparing the plaintiff’s prototype and drawings with
    the figures in the patent, contending that ‘‘all of the
    parties agreed that the ‘device’ referenced in the Novem-
    ber 4, 2004 agreement is the one contained in Aferzon’s
    hand drawings that he filed as a provisional patent
    application. . . . [The plaintiff’s] drawings and proto-
    types were created later and are not what the [agree-
    ment] is referring to in reciting ‘this device.’ ’’ (Citations
    omitted.) The defendants’ argument fails for two rea-
    sons. First, the court’s decision makes clear that it con-
    sidered the plaintiff’s prototype to be a link in the chain
    going from the initial drawings to the Solus, but ulti-
    mately the decision rested on comparing the initial
    device to the patented device.15 Second, the agreement
    clearly allows for consideration of the prototype. The
    defendants are correct that both Lyons and Aferzon
    testified that the ‘‘device’’ referenced in the agreement
    is that which is depicted in Aferzon’s initial design
    sketches. When the agreement states that the plaintiff
    is entitled to 50 percent of the total compensation
    resulting from the sale and/or licensing of the ‘‘above
    mentioned device, [or] versions of this device,’’ that
    portion of the agreement refers to Aferzon’s initial
    design sketches. (Emphasis added.) The latter portion
    of the sentence, however, covers ‘‘intellectual property
    developed associated with this device and/or versions
    of this device.’’ We read this portion of the agreement to
    cover intellectual property developed that is associated
    with versions of the device. Therefore, the court was
    not limited to considering the initial device but could
    also consider later versions of the initial device. The
    court thus looked at the prototype as just one link in
    a chain leading from the initial design sketches to the
    patent: ‘‘[T]his matter all started with a crude sketch
    from Aferzon. . . . [The plaintiff] turned that crude
    sketch into drawings and a prototype that was tested on
    a cadaver. That device was unquestionably an anterior
    intervertebral spinal fixation and fusion apparatus.
    Before any other prototype was created, Aferzon
    described in a patent application an anterior interverte-
    bral spinal fixation and fusion apparatus that included
    a cage and blades sufficiently similar to what [the plain-
    tiff] worked on for the court to find the device described
    in the patent to be ‘related’ to the device [the plaintiff]
    drew and prototyped.’’ Because the court found the
    prototype to be related to Aferzon’s initial design
    sketches, it was not improper for the court to consider
    the prototype as part of its analysis.
    We find no error in the manner in which the court
    interpreted the contract, and the court’s factual finding
    that the patented device is a version of the initial device
    stands unchallenged. Accordingly, we conclude that the
    court properly determined that the licensed patent and
    the device based on it are within the scope of the agree-
    ment.
    C
    The defendants next claim that the court improperly
    concluded that any applicable statute of limitations
    applicable to the plaintiff’s claims had been tolled,
    allowing the plaintiff to recover 50 percent of all com-
    pensation resulting from the sale and/or licensing of
    the patented device, dating back to 2010. The defen-
    dants argue that neither the fraudulent concealment
    doctrine nor the continuing course of conduct doctrine
    applies to the plaintiff’s claims as a matter of law. The
    plaintiff argues that the court correctly concluded that
    both doctrines apply. We agree with the defendants.
    We begin by setting forth the applicable standard of
    review. ‘‘Whether a particular action is barred by the
    statute of limitations is a question of law to which we
    apply a plenary standard of review.’’ Federal Deposit
    Ins. Corp. v. Owen, 
    88 Conn. App. 806
    , 814, 
    873 A.2d 1003
    , cert. denied, 
    275 Conn. 902
    , 
    882 A.2d 670
     (2005).
    The following additional facts and procedural history
    are relevant to this claim. The defendants pleaded and
    argued before the court that the plaintiff’s claims were
    barred by applicable statutes of limitations. As the court
    explained, this special defense could have had a signifi-
    cant impact on the plaintiff’s right of recovery because
    the defendants had first received compensation from
    Alphatec for the sale and/or licensing of the patented
    device as early as 2010: ‘‘As our Supreme Court
    explained in [Polizos v. Nationwide Mutual Ins. Co.,
    
    255 Conn. 601
    , 608–609, 
    767 A.2d 1202
     (2001)], whatever
    the limitation period is, it ordinarily begins to run, not
    when the breach is discovered, but instead from the
    breach itself, that is, from ‘the time when the plaintiff
    first could have successfully maintained an action.’ This
    poses a problem for [the plaintiff] because here, the
    first breach of the agreement that could have justified
    a lawsuit was in 2010, and this lawsuit wasn’t filed until
    2018.’’ The court declined, however, to rule on which
    statute of limitations applied to the plaintiff’s cause of
    action for breach of contract on the basis of its conclu-
    sion that the running of either statute would have been
    tolled under either the fraudulent concealment doctrine
    or the continuing course of conduct doctrine. By so
    ruling, the court rejected the defendants’ special
    defense under the applicable statute of limitations and
    held that the plaintiff was entitled to recover damages
    from the defendants for all royalty payments they had
    received for the sale and/or licensing of the patented
    device but had not shared with the plaintiff since the
    first royalty payment was received by them in 2010. We
    will address each doctrine in turn.
    1
    We first address the court’s conclusion that the fraud-
    ulent concealment doctrine tolled the running of the
    statute of limitations as to the defendants’ cause of
    action for breach of contract. The fraudulent conceal-
    ment doctrine is codified in General Statutes § 52-595,
    which provides: ‘‘If any person, liable to an action by
    another, fraudulently conceals from him the existence
    of the cause of such action, such cause of action shall
    be deemed to accrue against such person so liable there-
    for at the time when the person entitled to sue thereon
    first discovers its existence.’’
    ‘‘The question before us is whether the [plaintiff] [has]
    adduced any credible evidence that any of the defen-
    dants fraudulently concealed the existence of the [plain-
    tiff’s] cause of action. To meet this burden, it was not
    sufficient for the [plaintiff] to prove merely that it was
    more likely than not that the defendants had concealed
    the cause of action. Instead, the [plaintiff] had to prove
    fraudulent concealment by the more exacting standard
    of clear, precise, and unequivocal evidence. . . .
    Under our case law, to prove fraudulent concealment,
    the [plaintiff] [was] required to show: (1) a defendant’s
    actual awareness, rather than imputed knowledge, of
    the facts necessary to establish the [plaintiff’s] cause
    of action; (2) that defendant’s intentional concealment
    of these facts from the [plaintiff]; and (3) that defen-
    dant’s concealment of the facts for the purpose of
    obtaining delay on the [plaintiff’s] part in filing a com-
    plaint on their cause of action.’’ (Citations omitted;

    ‘‘[Additionally], the [defendants’] actions must have
    been directed to the very point of obtaining the delay
    [in filing the action] of which [the defendants] afterward
    [seek] to take advantage by pleading the statute.’’ (Inter-

     (2019).
    In concluding that the defendants had fraudulently
    concealed the cause of action for breach of contract
    from the plaintiff, the court first explained that the
    ‘‘pertinent fact here was that Aferzon was making
    money on the device and not sharing it with [the plain-
    tiff]. That first happened in 2010 when the ISI license
    to Alphatec resulted in the transfer of shares of Alphatec
    stock.’’ The court then focused on the following actions
    of the defendants, which it found to constitute fraudu-
    lent concealment: (1) failing to inform the plaintiff
    whenever money was earned from the sale of the
    device, despite their contractual duty to so inform it
    under the agreement, (2) the 2006 letter that Aferzon
    sent to Lyons claiming that the project was dormant
    and seeking to amend the agreement, in which the court
    found that Aferzon ‘‘intentionally chose, not only to
    conceal the facts from [the plaintiff], but to lie about
    the status of the project and put [the plaintiff] off its
    guard,’’ (3) Aferzon’s failure to respond to the two
    e-mails that Lyons sent to him in 2008 requesting an
    update on the project, (4) Aferzon’s and Bash’s transfer
    of their rights in the patent to a limited liability com-
    pany, (5) and Aferzon’s failure to respond to the two
    presuit letters that the plaintiff’s counsel sent to him
    in 2017 and 2018.16 Ultimately, the court concluded that
    ‘‘[t]he key factors permitting tolling for fraudulent con-
    cealment under the common law are all in place. [The
    plaintiff] diligently and repeatedly tried to discover from
    Aferzon—the most direct possible source—the status
    of the project. Aferzon knew the pertinent fact: the
    device was making money. Aferzon intentionally con-
    cealed that fact from [the plaintiff]. And not only did
    he conceal it, he deliberately threw [the plaintiff] off the
    scent by telling [it] the project wasn’t making sufficient
    progress to warrant continuing his deal with [the plain-
    tiff]. The court infers from this conduct that Aferzon
    was intentionally concealing this information from [the
    plaintiff] so that he might postpone the reckoning of a
    lawsuit for as many years as possible and, if possible,
    until it was too late. . . . Tolling under the doctrine
    of fraudulent concealment applies to the [plaintiff’s]
    claims through the time [the plaintiff] first learned the
    facts needed to support a claim.’’ (Footnote omitted.)
    The trial court’s conclusion is legally erroneous for
    two reasons. First, five of the six factual predicates on
    which the court relied legally cannot constitute fraudu-
    lent concealment because they occurred either before
    the plaintiff’s cause of action accrued or after the plain-
    tiff had become aware of that cause of action. To prove
    fraudulent concealment, the plaintiff must demonstrate
    the defendant’s actual awareness of the facts necessary
    to establish the plaintiff’s cause of action and its inten-
    tional concealment of these facts. See Bartone v. Robert
    L. Day Co., supra, 
    232 Conn. 533
    . The court found, and
    neither party has challenged, that ‘‘the first breach of
    the agreement that could have justified a lawsuit was
    in 2010’’ when ISI first received a royalty payment from
    Alphatec in the form of a transfer of Alphatec common
    stock. Aferzon’s letter in which he lied about the dor-
    mancy of the project, Lyons’ two e-mails that Aferzon
    failed to respond to, and Aferzon’s transfer of his patent
    rights to the ISI all occurred before any breach had
    occurred. The facts necessary to establish the cause of
    action did not exist when those events occurred, so it
    was impossible at those times for Aferzon either to
    have had actual awareness of the plaintiff’s nonexistent
    cause of action for breach of contract or to have inten-
    tionally concealed such a cause of action from the plain-
    tiff. See Flannery v. Singer Asset Finance Co., LLC,
    
    128 Conn. App. 507
    , 517, 
    17 A.3d 509
     (2011) (explaining
    that merely concealing existence of wrongdoing is
    insufficient to establish that defendant fraudulently
    concealed existence of plaintiff’s causes of action with
    intention of delaying plaintiff in commencing lawsuit),
    aff’d, 
    312 Conn. 286
    , 
    94 A.3d 553
     (2014). As for the two
    presuit letters sent by the plaintiff’s counsel to Aferzon,
    to which Aferzon failed to respond, the trial court
    explicitly found that the plaintiff had already learned
    the facts necessary to establish a cause of action for
    breach of contract by the time those letters were
    mailed.17 The statute of limitations can no longer be
    tolled from fraudulent concealment once the plaintiff
    has sufficient knowledge of the cause of action, as § 52-
    595 provides that the cause of action accrues once
    ‘‘the person entitled to sue thereon first discovers its
    existence.’’
    As for the remaining factual predicate on which the
    court relied as a basis for finding fraudulent conceal-
    ment, that Aferzon failed to notify the plaintiff whenever
    ISI received compensation resulting from the sale and/
    or licensing of the patented device, such conduct merely
    constituted nondisclosure, which, standing alone, can-
    not establish fraudulent concealment in the absence
    of a fiduciary duty. Generally, fraudulent concealment
    requires a showing of affirmative acts of concealment.
    See Falls Church Group, Ltd. v. Tyler, Cooper & Alcorn,
    LLP, 
    89 Conn. App. 459
    , 478, 
    874 A.2d 266
     (2005), aff’d,
    
    281 Conn. 84
    , 
    912 A.2d 1019
     (2007). The defendants
    acknowledge that ‘‘[o]nly in the context of a fiduciary
    relationship is there a possible exception where nondis-
    closure may suffice.’’ (Emphasis added.) The plaintiff
    describes the exception more definitively, stating that
    ‘‘a plaintiff may be able to prove the second ‘intentional
    concealment’ element by showing that ‘a defendant
    owed him a fiduciary duty and failed to disclose infor-
    mation as that duty required.’ ’’ The defendants are
    closer to the mark, as our Supreme Court has not held
    that, in the context of a fiduciary relationship, mere
    nondisclosure can satisfy the second element of fraudu-
    lent concealment. See Iacurci v. Sax, 
    313 Conn. 786
    ,
    792 n.8, 
    99 A.3d 1145
     (2014); Falls Church Group, Ltd.

    281 Conn. 84
    , 107–108,

     (2007). In Iacurci, commenting on a trial

    Cooper & Alcorn, LLP, 
    supra,
     
    281 Conn. 107
    , for the
    proposition that ‘‘nondisclosure is sufficient to satisfy
    the second element of fraudulent concealment when
    the ‘defendant has a fiduciary duty to disclose those
    facts’ ’’; Iacurci v. Sax, supra, 791–92; our Supreme
    Court explained its view of the controlling law as fol-
    lows: ‘‘This quotation cites a proposition that has gained
    general acceptance in federal cases applying Connecti-
    cut law. See, e.g., Fenn v. Yale University, 
    283 F. Supp. 2d 615
    , 636–37 (D. Conn. 2003). As the trial court
    acknowledged, however, this court has ‘not yet decided
    whether affirmative acts of concealment are always
    necessary’ to satisfy the second element of fraudulent
    concealment under § 52-595. . . . Falls Church Group,
    Ltd. v. Tyler, Cooper & Alcorn, LLP, 
    supra,
     
    281 Conn. 107
    . The trial court nonetheless proceeded as though a
    fiduciary’s mere nondisclosure, if found, could supplant
    the need for evidence of acts of intentional conceal-
    ment. The Appellate Court followed a similar course.
    See Iacurci v. Sax, [
    139 Conn. App. 386
    , 394 n.2, 
    57 A.3d 736
     (2012)]. We emphasize that, in Falls Church
    Group, Ltd., this court only explained, in the context
    of evaluating a vexatious litigation action, that a law
    firm had probable cause to believe that it could assert
    a fraudulent concealment claim in light of federal prece-
    dent allowing fiduciary nondisclosure to substitute for
    intentional concealment. Falls Church Group, Ltd. v.
    Tyler, Cooper & Alcorn, LLP, 
    supra,
     
    281 Conn. 103
    –105,
    107–108, 112. That is, in Falls Church Group, Ltd., this
    court did not actually adopt the federal approach of
    allowing fiduciary nondisclosure to substitute for the
    second element of a fraudulent concealment claim. Nor
    do we adopt the federal approach in the present case,
    as the parties have not brought it directly into dispute.
    Rather, in the present case, we will assume without
    deciding that a fiduciary’s nondisclosure could satisfy
    the second element of fraudulent concealment for the
    purpose of § 52-595.’’ (Emphasis in original.) Iacurci v.
    Sax, supra, 792 n.8.
    Our Supreme Court has not revisited this issue since
    Iacurci. ‘‘It is axiomatic that this court, as an intermedi-
    ate body, is bound by Supreme Court precedent and
    [is] unable to modify it . . . . [I]t is not within our
    province to reevaluate or replace those decisions.’’
    (Internal quotation marks omitted.) Coyle Crete, LLC
    v. Nevins, 
    137 Conn. App. 540
    , 560–61, 
    49 A.3d 770
    (2012). Accordingly, we follow our Supreme Court’s
    lead and assume without deciding that a fiduciary’s
    nondisclosure could satisfy the second element of
    fraudulent concealment. Here, however, the trial court
    never held that Aferzon owed the plaintiff a fiduciary
    duty.18 In the absence of such a duty, our Supreme
    Court’s guidance supports the conclusion that mere
    nondisclosure paired with an ordinary contractual duty
    to disclose is insufficient to establish fraudulent con-
    cealment. Iacurci v. Sax, supra, 
    313 Conn. 792
     n.8. The
    plaintiff argues, however, that the ‘‘[d]efendants . . .
    cite no binding authority holding that the second ele-
    ment of fraudulent concealment cannot also be proven
    by showing that a defendant intentionally, and for the
    specific purpose of delaying a plaintiff filing a com-
    plaint, violated an express contractual duty to disclose.’’
    The plaintiff is correct, but our review of the case law
    also confirms the contrary proposition—that no Con-
    necticut court has ever found nondisclosure sufficient
    to toll the statute of limitations in the absence of a
    fiduciary relationship. Given that our Supreme Court
    has declined to hold that nondisclosure is sufficient
    even with a fiduciary duty; see Iacurci v. Sax, supra,
    792 n.8; we decline to rule that violation of a contractual
    duty to disclose in the absence of a fiduciary duty is
    sufficient to constitute fraudulent concealment.
    We stress that the statute in question tolls the statute
    of limitations when a defendant ‘‘fraudulently conceals
    from [the plaintiff] the existence of the cause of such
    action . . . .’’ (Emphasis added.) General Statutes § 52-
    595. Merriam-Webster’s Collegiate Dictionary defines
    fraudulent as ‘‘characterized by, based on, or done by
    fraud . . . .’’ Merriam-Webster’s Collegiate Dictionary,
    supra, p. 498; Rivers v. New Britain, 
    288 Conn. 1
    , 17, 
    950 A.2d 1247
     (2008) (explaining that we look to dictionary
    definition of term to ascertain its commonly approved
    meaning in statutory interpretation). Fraud is defined
    as ‘‘deceit, trickery; intentional perversion of truth in
    order to induce another to part with something of value
    or to surrender a legal right; an act of deceiving or
    misrepresenting . . . .’’ Merriam-Webster’s Collegiate
    Dictionary, supra, p. 498. The defendants’ failure to
    notify the plaintiff that the sale or licensing of the pat-
    ented device had resulted in compensation was simply
    a breach of the agreement. There is no act of deceit,
    misrepresentation, or ‘‘perversion of truth’’ inherent in
    such conduct. Other than the actions discussed pre-
    viously, which occurred before the plaintiff’s cause of
    action for breach of contract accrued, the plaintiff can
    point to no evidence of additional fraudulent behavior
    by the defendants other than their repeated breaches
    of the agreement. Our review of the relevant case law
    and statutory language leads us to conclude that, in
    the absence of a fiduciary duty, there must be some
    fraudulent action beyond breaching one’s contractual
    duty to toll the statute of limitations. Accordingly, we
    find that the court erred in concluding that the fraudu-
    lent concealment doctrine applied to the defendants’
    actions.
    2
    We next address the court’s conclusion that the con-
    tinuing course of conduct doctrine applied to the defen-
    dants’ actions. The defendants argue that ‘‘the repeated
    breach of a contractual obligation to pay money,
    whether periodically or as royalties are earned, is not
    subject to the continuing course of conduct doctrine
    as a matter of law.’’ The plaintiff argues that the doctrine
    applies because the parties had a special relationship.
    We agree with the defendants.
    ‘‘In certain circumstances . . . we have recognized
    the applicability of the continuing course of conduct
    doctrine to toll a statute of limitations. Tolling does not
    enlarge the period in which to sue that is imposed by
    a statute of limitations, but it operates to suspend or
    interrupt its running while certain activity takes place.
    . . . Consistent with that notion, [w]hen the wrong
    sued upon consists of a continuing course of conduct,
    the statute does not begin to run until that course of
    conduct is completed.’’ (Citation omitted; internal quo-
    tation marks omitted.) Flannery v. Singer Asset
    Finance Co., LLC, 
    supra,
     
    312 Conn. 311
    . ‘‘[I]n order
    [t]o support a finding of a continuing course of conduct
    that may toll the statute of limitations there must be
    evidence of the breach of a duty that remained in exis-
    tence after the commission of the original wrong related
    thereto. That duty must not have terminated prior to
    commencement of the period allowed for bringing an
    action for such a wrong. . . . Where [our Supreme
    Court has] upheld a finding that a duty continued to
    exist after the cessation of the act or omission relied
    upon, there has been evidence of either a special rela-
    tionship between the parties giving rise to such a contin-
    uing duty or some later wrongful conduct of a defendant
    related to the prior act. . . . Furthermore, [t]he doc-
    trine of continuing course of conduct as used to toll a
    statute of limitations is better suited to claims where
    the situation keeps evolving after the act complained
    of is complete . . . .’’ (Citations omitted; internal quo-
    tation marks omitted.) Bellemare v. Wachovia Mortgage
    Corp.,

    284 Conn. 193
    , 
    931 A.2d 916
     (2007).
    Our Supreme Court has also recently clarified the
    difference between a continuing course of conduct and
    a related form of conduct called a ‘‘continuing viola-
    tion.’’ The court described the difference as follows:
    ‘‘Although this court has on occasion used both terms
    in a manner that would imply that they are interchange-
    able; see, e.g., Watts v. Chittenden, [
    301 Conn. 575
    ,
    587, 
    22 A.3d 1214
     (2011)]; the difference between these
    theories is not simply the circumstances in which they
    apply, but also the scope of recovery they afford. When
    there is a continuing violation, each breach gives rise
    to a new statute of limitations, and the plaintiff is enti-
    tled to recover for only those breaches that occurred
    within the statute of limitations. See Knight v. Colum-
    bus, [
    19 F.3d 579
    , 581 (11th Cir.)] (‘[w]here a continuing
    violation is found, the [plaintiff] can recover for any
    violations for which the statute of limitations has not
    expired’) [cert. denied, 
    513 U.S. 929
    , 
    115 S. Ct. 318
    , 
    130 L. Ed. 2d 280
     (1994)]; see also State v. Commission
    on Human Rights & Opportunities, [
    211 Conn. 464
    ,
    472–73, 
    559 A.2d 1120
     (1989)]. Thus . . . the [plaintiff]
    would be entitled to [recovery] only for the six year
    period preceding the filing of [its] claim, as well as
    prospective relief. Conversely, when there is a continu-
    ing course of conduct, the accrual of the cause of action
    is delayed, and the plaintiff is entitled to recover the
    full extent of his or her injuries, irrespective of when
    they commenced. See Handler v. Remington Arms Co.,
    
    144 Conn. 316
    , 321, 
    130 A.2d 793

    (2001).
    In concluding that the continuing course of conduct
    doctrine applied in this case, the court first character-
    ized the defendants’ actions as a series of distinct
    breaches: ‘‘Under the contract, each time the device
    made money, Aferzon had to notify [the plaintiff] and
    pay it 50 percent of the total compensation. Aferzon’s
    money depends on ISI’s money, which, in turn, depends
    upon sales of the Alphatec Solus. As the record reflects,
    those sales vary. They might even cease. But in the
    meantime, Aferzon signed a contract that calls for him
    to account for them when and if they come in. Indeed,
    Aferzon’s duty continues into the future, and he would
    commit no future breach so long as he honestly reports
    and shares the income. This means that each failure
    could easily be seen as its own breach with its own
    limitation period running from the point at which an
    installment of money was realized under the license.’’
    The court then engaged in a discussion of both continu-
    ing violation analysis and the continuing course of con-
    duct doctrine, referring to them interchangeably,19 cit-
    ing both Giulietti v. Giulietti, supra, 
    65 Conn. App. 813
    , a case concerning the continuing course of conduct
    doctrine, and Bouchard v. State Employees Retirement
    Commission, supra, 
    328 Conn. 345
    , a case predomi-
    nantly addressing a continuing violation theory and
    advising that the two theories are not interchangeable.
    Although the court initially stated that ‘‘[a]pplying the
    continuing violation doctrine to this case is attractive,’’
    it ultimately concluded that the continuing course of
    conduct doctrine applied. The court provided the fol-
    lowing reasons for its application of the continuing
    course of conduct doctrine: (1) the claim concerned
    ‘‘continued and repeated’’ wrongs, not just a onetime
    violation; (2) the past wrongs are identical to more
    recent wrongs, and ‘‘[t]reating them as all part of a
    single continuing wrong is far more efficient than mark-
    ing each missed payment and starting the clock running
    anew’’; and (3) ‘‘allowing the claims to be brought now
    will likely head off future breaches [because] the viola-
    tions have not only been continuous, they have been
    without judicial intervention and are thus likely to con-
    tinue into the future unless dealt with.’’ Additionally,
    the court held that Aferzon had a ‘‘specific, legally rec-
    ognized duty in contract that was continuing . . . .’’ It
    likened this relationship to a ‘‘special relationship’’ of
    the sort that can establish a continuing duty to a party.
    See Saint Bernard School of Montville, Inc. v. Bank of
    America, 
    312 Conn. 811
    , 835, 
    95 A.3d 1063
     (2014).
    The court’s conclusion is legally erroneous because
    the nature of the defendants’ breaches is incompatible
    with the continuing course of conduct doctrine. We
    look first to the definition of a continuing course of
    conduct. ‘‘[I]n order [t]o support a finding of a continu-
    ing course of conduct that may toll the statute of limita-
    tions there must be evidence of the breach of a duty that
    remained in existence after commission of the original
    wrong related thereto.’’ (Emphasis added; internal quo-
    tation marks omitted.) Flannery v. Singer Asset Finance
    Co., LLC, 
    supra,
     
    128 Conn. App. 513
    –14. Courts have
    found that such a duty continues to exist after the
    original wrong where there is ‘‘some later wrongful
    conduct of a defendant related to the prior act.’’ (Inter-
    nal quotation marks omitted.) Bellemare v. Wachovia
    Mortgage Corp., supra, 
    94 Conn. App. 608
    . Put another
    way, ‘‘a precondition for the operation of the continuing
    course of conduct doctrine is that the defendant must
    have committed an initial wrong upon the plaintiff.
    . . . A second requirement for the operation of [this
    doctrine] is that there must be evidence of the breach
    of a duty that remained in existence after commission of
    the original wrong related thereto.’’ (Emphasis added;
    internal quotation marks omitted.) Watts v. Chittenden,
    supra, 
    301 Conn. 585
    .
    This language suggests that a continuing course of
    conduct requires both an initial wrong and a subsequent
    continuing duty that are distinct from one another. In
    the present case, the breach of the duty to disclose
    is the initial wrong. After receiving compensation and
    failing to notify the plaintiff, the duty to disclose that
    compensation may continue into the future, but the
    breach of that duty is the initial wrong complained of.
    For example, in Sanborn v. Greenwald, 
    39 Conn. App. 289
    , 
    664 A.2d 803
    , cert. denied, 
    235 Conn. 925
    , 
    666 A.2d 1186
     (1995), this court summarized several cases in
    which our Supreme Court upheld application of the
    doctrine, identifying a distinct initial action and breach
    of a subsequent duty for each: ‘‘In Blanchette v. Barrett,
    [
    229 Conn. 256
    , 
    640 A.2d 74
     (1994)], the statute of limita-
    tions was tolled because of evidence that the defendant
    physician had failed to satisfy his duty of monitoring
    the plaintiff’s questionable breast condition. The court
    considered this to be later wrongful conduct that related
    to the defendant’s [initial] diagnosis of the plaintiff. Id.,
    275. In Cross v. Huttenlocher, 
    185 Conn. 390
    , 
    440 A.2d 952
     (1981), the statute of limitations was tolled because
    of the negligent failure of a physician to warn a patient
    of the harmful side effects of a drug that the physician
    had prescribed and that the patient had continued to
    ingest over a period of time. In Giglio v. Connecticut
    Light & Power Co., 
    180 Conn. 230
    , 
    429 A.2d 486
     (1980),
    the statute of limitations was tolled because the installer
    of a pilot light gave repeated instructions as to its use
    in response to multiple complaints by the plaintiff. In
    Handler v. Remington Arms Co., supra, 
    144 Conn. 316
    ,
    the statute of limitations was tolled by the defendant
    manufacturer’s continuing failure to warn of the poten-
    tial danger associated with an inherently dangerous
    cartridge of ammunition. In each of these cases, the
    plaintiff’s injury was perpetuated, enhanced and even
    caused by the breach of a duty on the part of the defen-
    dant.’’ Sanborn v. Greenwald, supra, 296. We also note
    that this court has expressed skepticism as to whether
    the doctrine should ever be applied to breach of con-
    tract claims: ‘‘[T]he continuing course of conduct doc-
    trine is one classically applicable to causes of action
    in tort, rather than in contract. The doctrine concerns
    itself with ‘wrongs,’ the nomenclature of tort, not with
    ‘breach,’ the language of contract.’’ Fradianni v. Protec-
    tive Life Ins. Co., 
    145 Conn. App. 90
    , 100 n.9, 
    73 A.3d 896
    , cert. denied, 
    310 Conn. 934
    , 
    79 A.3d 888
     (2013).
    These cases demonstrate that repeated and distinct
    violations of a duty to disclose are not what is contem-
    plated by the definition of a continuing course of con-
    duct. ‘‘[T]he continuing course of conduct doctrine rec-
    ognizes that the act or omission that commences the
    limitation period may not be discrete and attributable
    to a fixed point in time. [T]he doctrine is generally
    applicable under circumstances where [i]t may be
    impossible to pinpoint the exact date of a particular
    negligent act or omission that caused injury . . . .’’

    William Kramer & Associates, LLC, 
    331 Conn. 493
    , 503,
    
    205 A.3d 534
     (2019). Here, the defendants repeatedly
    breached the agreement, and every breach is readily
    identifiable. The plaintiff entered exhibits clearly delin-
    eating the date and amount of each distinct royalty
    payment which the defendants received from Alphatec
    without notifying the plaintiff. ‘‘[T]he continuing course
    of conduct doctrine reflects the policy that, during an
    ongoing relationship, lawsuits are premature because
    specific tortious acts or omissions may be difficult to
    identify and may yet be remedied.’’ (Internal quotation
    marks omitted.) Saint Bernard School of Montville, Inc.
    v. Bank of America, supra, 
    312 Conn. 837
    –38.
    On the other hand, with respect to what constitutes
    a continuing violation, our Supreme Court cited with
    approval the following explanation: ‘‘In between the
    case in which a single event gives rise to continuing
    injuries and the case in which a continuous series of
    events gives rise to a cumulative injury is the case in
    which repeated events give rise to discrete injuries, as
    in suits for lost wages. If our plaintiff were seeking
    [back pay] for repeated acts of wage discrimination
    (suppose that every [payday] for five years he had
    received $100 less than he was entitled to), he would
    not be permitted to reach back to the first by suing
    within the [limitation] period for the last. . . . [In such
    a case] the damages from each discrete act . . . would
    be readily calculable without waiting for the entire
    series of acts to end. There would be no excuse for
    the delay.’’ (Citations omitted; internal quotation marks
    omitted.) Watts v. Chittenden, supra, 
    301 Conn. 588
    –89.
    The case at hand is akin to the latter scenario.20
    In Fradianni v. Protective Life Ins. Co., supra, 
    145 Conn. App. 90
    , this court reviewed whether the continu-
    ing course of conduct doctrine applied to a life insur-
    ance company’s conduct in annually overcharging the
    plaintiff. Citing the previously quoted passage from
    Watts, this court concluded that the defendant’s actions
    were more accurately characterized as a series of dis-
    tinct breaches, and thus held as follows that the continu-
    ing course of conduct doctrine did not apply to the
    plaintiff’s claim: ‘‘The case now before us, where the
    plaintiff alleges that the defendant breached the insur-
    ance contract annually, at precisely identifiable
    moments when it allegedly overcharged the plaintiff, is
    analogous to the suit for lost wages as described [in
    Watts v. Chittenden, supra, 
    301 Conn. 588
    –89]. The
    plaintiff’s damages arising from the defendant’s alleged
    breaches were readily calculable and actionable at the
    time of breach, unlike those cases where it is the cumu-
    lative effect of the defendant’s behavior that gives rise
    to the injury. Simply put, the plaintiff’s allegations do
    not constitute a ‘course of conduct’ by the defendant;
    but instead allege a series of repeated breaches over a
    period of years. Accordingly, the continuing course of
    conduct doctrine is inapplicable to the present case.
    We, therefore, conclude that the court properly found
    that the doctrine did not serve to toll the [statute of
    limitations].’’ (Footnote omitted.) Fradianni v. Protec-
    tive Life Ins. Co., supra, 100. The present case, like
    Fradianni, involves a series of separate breaches to
    which the continuing course of conduct doctrine does
    not apply because each such breach caused separate
    damages that were readily calculable at the time of
    breach.
    Lastly, we address the court’s conclusion that the
    parties had a special relationship. The existence of a
    special relationship between the parties is another basis
    for establishing the continuation of a duty between
    them after an initial wrong has been committed. See
    Bellemare v. Wachovia Mortgage Corp., supra, 
    94 Conn. App. 608
    . The court concluded that the parties had a
    special relationship because Aferzon ‘‘[had] a specific,
    legally recognized duty in contract that was continuing
    and required [him] to report his gains from the device
    idea to [the plaintiff].’’
    ‘‘Our appellate courts have not defined precisely what
    constitutes a special relationship for purposes of tolling
    because the existence of such a relationship will depend
    on the circumstances that exist between the parties
    and the nature of the claim at issue. Usually, such a
    special relationship is one that is built upon a fiduciary
    or otherwise confidential foundation. A fiduciary or
    confidential relationship is characterized by a unique
    degree of trust and confidence between the parties, one
    of whom has superior knowledge, skill or expertise and
    is under a duty to represent the interests of the other.
    . . . The superior position of the fiduciary or dominant
    party affords him great opportunity for abuse of the
    confidence reposed in him. . . . Fiduciaries appear in
    a variety of forms, including agents, partners, lawyers,
    directors, trustees, executors, receivers, bailees and
    guardians. . . . The fact that one [businessperson]
    trusts another and relies on [that person] to perform [his
    obligations] does not rise to the level of a confidential
    relationship for purposes of establishing a fiduciary
    duty. . . . [N]ot all business relationships implicate the
    duty of a fiduciary. . . . In the cases in which this court
    has, as a matter of law, refused to recognize a fiduciary
    relationship, the parties were either dealing at arm’s
    length, thereby lacking a relationship of dominance and
    dependence, or the parties were not engaged in a rela-
    tionship of special trust and confidence. . . . Accord-
    ingly, a mere contractual relationship does not create
    a fiduciary or confidential relationship.’’ (Citations
    omitted; internal quotation marks omitted.) Saint Ber-
    nard School of Montville, Inc. v. Bank of America,
    supra, 
    312 Conn. 835
    –36.
    The plaintiff and Aferzon clearly were dealing with
    each other at arm’s length in the course of an ordinary
    contractual relationship. The court made no factual
    findings indicating that the parties had a confidential
    relationship or that there was a unique degree of trust
    and confidence between them. The court did make find-
    ings as to Aferzon’s medical background and lengthy
    surgical experience, but it did not make any finding
    that Aferzon had any ‘‘superior knowledge, skill or
    expertise’’ as to the development of medical devices,
    which is the subject of this agreement. The only justifi-
    cation that the court provided for this finding was that
    Aferzon had a specific and continuing duty to report
    any compensation to the plaintiff, but this is merely the
    contractual obligation imposed on him by the agree-
    ment. Such a duty alone is insufficient to establish a
    special relationship.
    Because there was no evidence before the court that
    would have supported a finding that a special relation-
    ship existed between the parties, and Aferzon’s
    breaches more accurately are characterized as a series
    of distinct, readily calculable breaches of the parties’
    agreement, the trial court erred in concluding that the
    continuing course of conduct doctrine tolled the run-
    ning of the statute of limitations.
    3
    Our conclusion that the trial court improperly con-
    cluded that the running of the statute of limitations had
    been tolled as to the plaintiff’s breach of contract claim
    now raises the necessary questions of what statute of
    limitations applies to that claim and to what extent
    can the plaintiff recover expectation damages for the
    defendants’ proven breaches of the parties’ contract.
    Rather than remand these issues to the trial court for
    consideration in the first instance, we review them now
    on the basis of the trial court’s unchallenged factual
    findings.21 We note that the record is adequate for
    review of these issues, and neither determination
    requires further factual development. We rely on the
    court’s express factual findings, which were based on
    unchallenged facts and exhibits. We address each issue
    in turn.
    a
    We first address which statute of limitations applies
    to the plaintiff’s claims. The determination of which
    statute of limitations applies to an action is a question
    of law over which our review is plenary. See, e.g., Pasco
    Common Condominium Assn., Inc. v. Benson, 
    192 Conn. App. 479
    , 501, 
    218 A.3d 83
     (2019).
    The court stated that, ‘‘[f]or written contracts, the
    limitation period is established as a six year period
    . . . . For oral contracts the limitation period is estab-
    lished as a three year period . . . .’’ The distinction,
    however, is not that simple. All contracts have a six
    year statute of limitations except for those that are both
    oral and executory. ‘‘General Statutes § 52-581 provides
    a three year statute of limitations for executory oral
    contracts. . . . All other contracts are governed by a
    six year statute of limitations pursuant to General Stat-
    utes § 52-576.’’ (Citation omitted.) Mitchell v. Guardian
    Systems, Inc., 
    72 Conn. App. 158
    , 161 n.3, 
    804 A.2d 1004
    , cert. denied, 
    262 Conn. 903
    , 
    810 A.2d 269
     (2002).
    ‘‘This court has addressed the distinction between
    §§ 52-581 and 52-576. These two statutes, each estab-
    lishing a different period of limitation, can both be inter-
    preted to apply to actions on oral contracts. Our
    Supreme Court has distinguished the statutes, however,
    by construing § 52-581, the three year statute of limita-
    tions, as applying only to executory contracts. . . . A
    contract is executory when neither party has fully per-
    formed its contractual obligations and is executed when
    one party has fully performed its contractual obliga-
    tions. . . . It is well established, therefore, that the
    issue of whether a contract is oral is not dispositive of
    which statute applies. Thus, the . . . argument that
    § 52-581 automatically applies to [an] oral contract
    between . . . parties is incorrect. The determinative
    question is whether the contract was executed.’’(Em-
    phasis in original; internal quotation marks omitted.)

    284 Conn. 931
    , 
    934 A.2d 246
     (2007).
    The contract between the parties in the present case
    is not executory, as it cannot be said that neither party
    has fully performed its contractual obligations thereun-
    der. There may have been some dispute as to the extent
    of the plaintiff’s obligations before the trial court, but
    neither party has challenged the court’s factual finding
    that the plaintiff fully performed its contractual obliga-
    tions thereunder. Accordingly, the six year statute of
    limitations set forth in § 52-576 applies to the plaintiff’s
    breach of contract claim.
    b
    We next address the extent of the plaintiff’s recovery
    for breaches of contract occurring within the applicable
    six year period of limitation.
    The court characterized the defendants’ breaches as
    distinct and readily calculable: ‘‘[T]his case involves a
    series of breaches, not just one. . . . [E]ach failure
    could easily be seen as its own breach with its own
    limitation period running from the point at which an
    installment of money was realized under the license.’’
    As we have previously explained, such conduct consti-
    tutes what our Supreme Court in Bouchard has called
    a continuing violation rather than a continuing course
    of conduct: ‘‘When there is a continuing violation, each
    breach gives rise to a new statute of limitations, and
    the plaintiff is entitled to recover for only those
    breaches that occurred within the statute of limita-
    tions.’’ Bouchard v. State Employees Retirement Com-
    mission, supra, 
    328 Conn. 374
     n.14. Accordingly,
    determining what portion of the plaintiff’s expectation
    damages, as awarded by the court, were properly
    awarded to it for breaches that occurred within the six
    year limitation period is a simple matter of drawing a
    line six years back from the date the plaintiff com-
    menced this action, adding together all payments
    received by the defendants since that date from the
    sale and/or licensing of the patented device, and divid-
    ing that sum in half to calculate the plaintiff’s 50 percent
    share of such payments. The resulting total of such
    properly awarded expectation damages for breach of
    contract is $996,039.97.
    Service was effectuated on July 16, 2018. See Doe v.
    West Hartford, 
    328 Conn. 172
    , 177 n.4, 
    177 A.3d 1128
    (2018) (‘‘[t]ypically, an action is ‘commenced,’ for pur-
    poses of determining compliance with a statute of limi-
    tations, when the defendant is served with a summons
    and complaint’’). Thus, the plaintiff was properly
    awarded its 50 percent share of all royalty payments
    received by the defendants for sale and/or licensing of
    the Solus as far back as July 16, 2012. The plaintiff
    submitted, and the court credited the facts presented
    in, plaintiff’s exhibit 16, which lists every payment ISI
    received from Alphatec, after they entered into their
    cross license agreement, from 2010 to 2019. For each
    such payment, exhibit 16 sets forth the amount of the
    payment, the date on which it was received by ISI, a
    calculation of 50 percent of its total value representing
    the plaintiff’s share of the payment under the parties’
    agreement, and the plaintiff’s proposal for an award of
    prejudgment interest under § 37-3a based on the defen-
    dants’ wrongful detention of the plaintiff’s share of that
    payment from the date of its receipt until May 4, 2020,
    calculated at the maximum statutory rate of 10 percent
    per year. These facts and figures are not in dispute.
    The parties had the opportunity to challenge the court’s
    adoption of the facts set forth in exhibit 16 as its basis
    for awarding the plaintiff expectation damages and pre-
    judgment interest at the lesser rate of 4.5 percent per
    year, but neither party did so.
    Starting in July, 2012, the first payment made by
    Alphatec to the defendants as compensation for the
    sale and/or licensing of the patented device within the
    six year limitation period, was received by ISI on July 26,
    2012. The plaintiff was properly awarded expectation
    damages totaling 50 percent of the sum of that first
    payment and of all subsequent payments of royalties
    for the sale and/or licensing of the patented device that
    the defendants received within the six year limitation
    period. The total of all expectation damages awarded
    by the court on the basis of the defendants’ failure to
    pay the plaintiff its 50 percent share of all compensation
    that they had received for the sale and/or licensing of
    the patented device within the six year limitation period
    was $996,039.97. Accordingly, the court’s judgment for
    the plaintiff on its claim of breach of contract must be
    adjusted downward to that amount.
    This also raises the issue of whether the court appro-
    priately subtracted $50,000 for development expenses
    from the plaintiff’s recovery. On October 1, 2009, ISI
    received a $50,000 payment from Alphatec that the
    defendants claimed was reimbursement for expenses
    related to acquiring the patent for the device. The court
    credited the defendants’ characterization of this pay-
    ment and did not allow the plaintiff to recover on it,
    explaining that the contract did not contemplate recov-
    ery by the plaintiff based on any payment that was not
    actually a royalty payment: ‘‘[T]he evidence does show
    that Alphatec denominated $50,000 of the money it paid
    as an expense reimbursement. The evidence also shows
    expenses that amount to nearly $50,000 for patent
    related expenses incurred at a time when they were
    most likely legitimate expenses associated with acquir-
    ing the anterior patent. Knowing that the agreement
    called for future agreement about ‘financial commit-
    ments,’ the court concludes that this is a reasonable
    sum for expenses under the [plaintiff’s] contract terms
    and would have been part of the bargain had it been
    carried out. . . . On the breach of contract claim, [the
    plaintiff] is due only what it could reasonably expect
    to have received under the contract. If the court were
    to punish Aferzon rather than hold him as best we
    can to his bargain, it would have to apply a different
    standard, not ordinary damages analysis. In the mean-
    time, despite problems posed by Aferzon himself, the
    court’s job is to give [the plaintiff] the benefit of its
    bargain. That benefit was expected to exclude required
    financial commitments, and the court is convinced that,
    unlike the other sums claimed, this $50,000 sum is more
    likely than not a genuine expense reimbursement asso-
    ciated with the anterior patent. This means [the plain-
    tiff’s] expectation damages are $1,637,389 minus
    $50,000 or $1,587,289.’’
    The court’s foregoing explanation makes it clear that
    the plaintiff requested total expectation damages of
    $1,637,289 for breach of contract on the basis of the
    defendants’ failure to pay it all sums listed in exhibit
    16, each of which it claimed to have been its 50 percent
    share of a payment received by the defendants from
    Alphatec in the course of their cross license agreement.
    Although the court recognized that one such listed sum,
    in the amount of $25,000, was not recoverable for
    breach of contract because it constituted 50 percent of
    the initial $50,000 reimbursement payment, it unac-
    countably included that sum in its calculation of the
    plaintiff’s total expectation damages award, then sub-
    tracted twice that amount—the full $50,000 reimburse-
    ment payment on which it was based—from the plain-
    tiff’s total award.
    Whether the court erred in including the $25,000
    improperly claimed by the plaintiff as unshared com-
    pensation resulting from the sale and/or licensing of
    the patented device or in subtracting from that award
    the entire $50,000 reimbursement payment from which
    that $25,000 sum was calculated, we need not make
    similar modifications of the plaintiff’s adjusted award
    of expectation damages to reflect what the defendants
    failed to pay it under the November 4, 2004 agreement
    from compensation it received within the six year limi-
    tation period. The reason for this conclusion is simply
    that the $50,000 reimbursement payment was received
    by the defendant before that six year limitation period
    began. Accordingly, there is no reason to subtract any
    amount from the plaintiff’s expectation damages to
    account for that payment because it is not included in
    the new total to begin with. The plaintiff’s recoverable
    expectation damages for breach of contract must there-
    fore be reduced to $996,039.97, as previously noted, in
    light of our conclusion as to the viability of the defen-
    dants’ special defense under the statute of limitations.
    Lastly, we must determine what portion of the pre-
    judgment interest awarded to the plaintiff under § 37-
    3a for the defendants’ allegedly wrongful detention of
    money due and owing to the plaintiff prior to judgment
    was properly based on the defendants’ actionable fail-
    ure to pay the plaintiff its 50 percent share of all com-
    pensation received by the defendants for the sale and/
    or licensing of the patented device within the six year
    limitation period. When the court made its initial award
    of prejudgment interest in its memorandum of decision
    of April 22, 2020, it improperly awarded interest on all
    sums claimed by the plaintiff as expectation damages
    for breach of contract in exhibit 16, including several
    sums claimed on the basis of payments received by the
    defendants outside of the six year limitation period.
    The total interest so awarded must also be adjusted
    downward to exclude all sums improperly awarded to
    the plaintiff for the detention of moneys to which the
    plaintiff did not become entitled within the six year
    limitation period. The court later compounded this
    error by awarding the plaintiff an additional sum of
    prejudgment interest on the basis of the defendants’
    further alleged detention of those same sums for an
    additional 140 days beyond May 4, 2020, until final judg-
    ment was rendered on September 21, 2020. That addi-
    tional award of prejudgment interest must also be
    reduced to exclude from it all interest improperly
    awarded on the basis of the alleged detention of sums
    which the plaintiff was barred from recovering by the
    statute of limitations.
    The total prejudgment interest properly awarded by
    the court on the basis of the defendants’ wrongful deten-
    tion of the plaintiff’s 50 percent shares of compensation
    received for the sale and/or licensing of the patented
    device within the six year limitation period must be
    determined in two steps. First, as to sums properly
    awarded to the plaintiff in the court’s memorandum of
    decision through May 4, 2020, we need only add together
    all awards of prejudgment interest on those sums, as
    proposed by the plaintiff on exhibit 16 at the rate of 10
    percent per year, and multiply that total by 0.45 to
    refigure such interest, as the court did, at the lower
    rate of 4.5 percent per year. The total of such properly
    awarded interest through May 4, 2020, as included in
    the larger award of interest ordered by the court in its
    memorandum of decision, is $191,748.60.
    Finally, we must adjust the end date for the calcula-
    tion of prejudgment interest from May 4, 2020, to Sep-
    tember 21, 2020, which the court did when it rendered
    final judgment for the plaintiff. The court, however, did
    not calculate separate awards of additional prejudg-
    ment interest for each payment to which it found that
    the plaintiff was entitled on the basis of the defendants’
    further detention of the plaintiff’s recoverable damages
    until September 21, 2020. Instead, it ordered an increase
    in the total award of prejudgment interest it had pre-
    viously ordered in its memorandum of decision on the
    basis of the further detention of all sums requested by
    the plaintiff as expectation damages, as listed in exhibit
    16. To calculate what portion of that additional prejudg-
    ment interest award was ordered appropriately on the
    basis of the further wrongful detention of moneys to
    which the plaintiff became entitled during the six year
    limitation period, we must first determine what percent-
    age of all expectation damages requested by the plaintiff
    in exhibit 16 the plaintiff’s wrongfully withheld damages
    represented. Then, we must multiply the court’s total
    additional prejudgment interest award by the decimal
    equivalent of that percentage to determine how much
    of such additional interest was properly awarded. Here,
    where the total expectation damages requested by the
    plaintiff in exhibit 16 was $1,637,289.04 and the total
    expectation damages lawfully claimed by the plaintiff
    for the defendants’ breaches of contract within the limi-
    tation period was $996,039.97, the percentage of all
    requested damages which the plaintiff’s recoverable
    damages represented was 60.8347 percent. By multi-
    plying the court’s total award of additional prejudgment
    interest, $28,240.20, by the decimal equivalent of that
    percentage, 0.608347, we calculate that the additional
    prejudgment interest that the court properly awarded
    to the plaintiff based on the defendants’ continuing
    wrongful detention of moneys recoverable by it from
    May 4, 2020, to September 21, 2020, was $17,179.84.
    By adding that sum to the $191,748.60 in prejudgment
    interest that the court properly awarded to the plaintiff
    in its memorandum of decision on the basis of the
    defendants’ previous wrongful detention of those same
    recoverable expectation damages until May 4, 2020, we
    have determined that the court properly awarded the
    plaintiff a total of $208,928.44 in prejudgment interest.
    By adding that adjusted, $208,928.44 award of prejudg-
    ment interest to the plaintiff’s adjusted, $996,039.97
    award of expectation damages for breaches of contract
    occurring within the six year limitation period for
    breach of contract claims, we calculate the plaintiff’s
    proper adjusted total award for breaches of contract
    occurring within that limitation period as $1,204,968.41.
    D
    We next address whether the court appropriately
    awarded the plaintiff attorney’s fees and costs under
    CUTPA. The defendants argue that, because the two
    tolling doctrines that the court improperly applied in
    rejecting their statute of limitations defense to the plain-
    tiff’s breach of contract claim are inapplicable to claims
    under CUTPA, the court improperly considered evi-
    dence of conduct occurring outside of the three year
    statute of limitations for CUTPA claims set forth in § 42-
    110g as a basis for concluding that they had violated
    CUTPA. The plaintiff responds that, even if the running
    of the CUTPA statute of limitations was not tolled by the
    fraudulent concealment doctrine and/or the continuing
    course of conduct doctrine, a substantial number of
    the defendants’ bad faith breaches of contract on which
    the court based its finding of a CUTPA violation
    occurred within the three year CUTPA statute of limita-
    tions. Although we have already found that there is
    insufficient evidence to support the plaintiff’s claims
    of tolling under either the fraudulent concealment doc-
    trine or the continuing course of conduct doctrine, and
    thus agree with the defendants that its conduct outside
    of the three year limitation period cannot be found to
    have constituted an actionable CUTPA violation in this
    case, we agree with the plaintiff that the court’s finding
    of a CUTPA violation must still be upheld on the basis
    of the defendants’ proven bad faith breaches of contract
    that occurred within the statute of limitations, and thus
    that attorney’s fees were properly awarded to it for the
    prosecution of that claim. Even so, because the court
    awarded attorney’s fees for prosecution of both the
    timely and the untimely portions of the plaintiff’s
    CUTPA claim, we conclude that the case must be
    remanded to the trial court for a determination, if possi-
    ble, of what portion of such attorney’s fees were reason-
    ably incurred to prosecute the timely portion of the
    plaintiff’s claim.
    The following additional facts and procedural history
    are relevant to this claim. In reviewing the plaintiff’s
    CUTPA claim, the court first concluded that the parties’
    transactions were subject to CUTPA: ‘‘There can’t be
    any doubt that this was a business transaction between
    the parties and that [the plaintiff] came out the financial
    loser. So, the real focus of inquiry here should be
    whether what Aferzon did and made ISI do was culpable
    enough to label an unfair trade practice.’’ The court
    then concluded that Aferzon had violated CUTPA by
    breaching the agreement in bad faith, and listed several
    actions by him that supported its conclusion that he
    had so acted: ‘‘The court believes the evidence is clear
    and convincing that Aferzon breached his agreement
    not prompted by an honest mistake as to his rights or
    duties, but by an interested or sinister motive. Specifi-
    cally, the court concludes that Aferzon knew he had
    an obligation to [the plaintiff] but contrived a variety
    of unscrupulous means to deprive [the plaintiff] of what
    it was due. He lied to [the plaintiff] about the status of
    the project. He ignored [its] requests for information. He
    disregarded two demands from lawyers. He contrived
    [a limited liability company] at least in part as a way
    to frustrate his agreement. He fabricated expenses to
    cause it to appear that the idea at issue wasn’t profitable.
    He concealed his activities until the normal statute of
    limitations period expired and then invoked it in his
    defense.’’ The court declined to award punitive damages
    or further compensatory damages for the violation but
    awarded attorney’s fees under CUTPA. On September
    15, 2020, the court awarded the plaintiff $756,000 in
    attorney’s fees and expenses. The defendants do not
    challenge the amount of the award but argue that the
    award of attorney’s fees was legally erroneous.
    We first set forth our standard of review. Section 42-
    110g (d) provides in relevant part: ‘‘In any action
    brought by a person under this section, the court may
    award, to the plaintiff, in addition to the relief provided
    in this section, costs and reasonable attorneys’ fees
    based on the work reasonably performed by an attorney
    and not on the amount of recovery. . . .’’ ‘‘Awarding
    . . . attorney’s fees under CUTPA is discretionary [pur-
    suant to] § 42-110g (a) and (d) . . . and the exercise
    of such discretion will not ordinarily be interfered with
    on appeal unless the abuse is manifest or injustice
    appears to have been done. . . . The salient inquiry is
    whether the court could have reasonably concluded as
    it did. . . . [T]he term abuse of discretion does not
    imply a bad motive or wrong purpose but merely means
    that the ruling appears to have been made on untenable
    grounds.’’ (Internal quotation marks omitted.) MedVa-

     (2008).
    Because a finding of liability under CUTPA is a neces-
    sary prerequisite to an award of attorney’s fees under
    CUTPA, we also set forth the applicable standard of
    review for a finding that a defendant violated CUTPA.

    239 A.3d 319

    Section 42-110g (a) provides in relevant part: ‘‘Any per-
    son who suffers any ascertainable loss of money or
    property, real or personal, as a result of the use or
    employment of a method, act or practice prohibited by
    [§] 42-110b, may bring an action . . . to recover actual
    damages. . . .’’ In other words, ‘‘CUTPA provides that
    [n]o person shall engage in unfair methods of competi-
    tion and unfair or deceptive acts or practices in the
    conduct of any trade or commerce.’’ (Internal quotation

    ‘‘It is well settled that in determining whether a prac-
    tice violates CUTPA we have adopted the criteria set
    out in the cigarette rule by the [F]ederal [T]rade [C]om-
    mission for determining when a practice is unfair: (1)
    [W]hether the practice, without necessarily having been
    previously considered unlawful, offends public policy
    as it has been established by statutes, the common law,
    or otherwise—in other words, it is within at least the
    penumbra of some common law, statutory, or other
    established concept of unfairness; (2) whether it is
    immoral, unethical, oppressive, or unscrupulous; (3)
    whether it causes substantial injury to consumers,
    [competitors or other businesspersons] . . . . All
    three criteria do not need to be satisfied to support a
    finding of unfairness. A practice may be unfair because
    of the degree to which it meets one of the criteria or
    because to a lesser extent it meets all three. . . . To
    the extent that [an appellant] is challenging the trial
    court’s interpretation of CUTPA, our review is plenary.

    .
    The defendants are correct that the court engaged
    in no discussion of whether a statute of limitations
    applied to the plaintiff’s CUTPA claim. Rather, when it
    discussed fraudulent concealment and continuing
    course of conduct, the court generally concluded, with-
    out narrowing its focus to particular claims, that ‘‘[t]his
    lawsuit is not barred by the statute of limitations.’’
    (Emphasis added.) Section 42-110g (f) provides that
    ‘‘[a]n action under this section may not be brought more
    than three years after the occurrence of a violation of
    this chapter.’’ The court did not discuss the applicable
    statute of limitations or whether fraudulent conceal-
    ment or a continuing course of conduct by the defen-
    dants could toll the running of that statute of limita-
    tions.22 The defendants argue that neither fraudulent
    concealment nor a continuing course of conduct can
    toll the statute of limitations for a claim under CUTPA.
    See Fichera v. Mine Hill Corp., 
    207 Conn. 204
    , 216, 
    541 A.2d 472
     (1988). Although it does not appear that our
    courts have squarely addressed this issue, we need not
    reach the issue here because we have concluded that
    neither doctrine applies to the defendants’ conduct in
    this case, nor, by extension, to their special defenses
    under any pleaded statute of limitations. See part I C
    of this opinion.
    Accordingly, the defendants argue that, of the con-
    duct described by the court in its discussion of CUTPA,
    ‘‘[t]he only activities occurring within the three years
    prior to [the plaintiff’s] suit are Aferzon’s disregarding of
    [the plaintiff’s] lawyers’ letters and his alleged litigation
    conduct,’’ which actions assertedly cannot constitute
    CUTPA violations. It is clear from the court’s memoran-
    dum of decision, however, that not all of the defendants’
    actions, as described by the court, were claimed to
    constitute unfair trade practices in violation of CUTPA
    but instead were described as evidence supporting the
    court’s conclusion that Aferzon’s breaches of the par-
    ties’ agreement were made in bad faith, and that such
    bad faith breaches of contract are what constituted
    the alleged CUTPA violations. The court explained that
    ‘‘[o]rdinary contract breaches are not unfair trade prac-
    tices. Breaches made in bad faith can be unfair trade
    practices. . . . This court believes the evidence is clear
    and convincing that Aferzon breached his agreement
    not prompted by an honest mistake as to his rights or
    duties, but by an interested or sinister motive.’’ As the
    court explained, the defendants breached the agree-
    ment every time ISI received a payment from Alphatec
    and failed to notify or compensate the plaintiff per the
    agreement. ISI received thirty-four royalty payments for
    the sale and/or licensing of the patented device between
    2010 and 2019, which it failed to share with the plaintiff
    in breach of the parties’ agreement. Thirteen of those
    breaches occurred within the three year limitation
    period preceding the date of commencement of this
    action on July 16, 2018. Therefore, we review the court’s
    decision awarding attorney’s fees for the prosecution
    of the plaintiff’s claim by addressing whether those
    thirteen breaches of contract are sufficient to establish
    a CUTPA violation.
    First, we note that the court is correct that bad faith
    breaches of contract, but not ordinary breaches, can be
    found to constitute unfair trade practices under CUTPA.

    claim may be sufficient to establish a CUTPA violation’’;

    negligent or incompetent, in which case the CUTPA
    claim was barred, or whether the defendant’s actions
    would support a finding of intentional, reckless, unethi-

    In Landmark Investment Group, LLC v. Chung Fam-

    125 Conn. App. 678
    , this court upheld a finding that the defendant had
    violated CUTPA by terminating an agreement in bad
    faith. The trial court listed nine factual findings in sup-
    port of this conclusion. 
    Id.,
     705–706. This court ruled
    that none of those findings was clearly erroneous, and
    affirmed the finding of bad faith. 
    Id., 708
    . The court’s
    ultimate conclusion was as follows: ‘‘The [trial] court’s
    findings reveal that the defendant engaged in a pattern
    of bad faith conduct, seeking to escape its contractual
    obligations unfairly while negotiating a more favorable
    offer with . . . a third party. Given the wrongful termi-
    nation and the aggravating circumstances, there is
    ample support for the trial court’s conclusion that the
    defendant’s actions violated CUTPA. Therefore, the
    court’s finding of a CUTPA violation was not clearly
    erroneous.’’ 
    Id.
    We begin with the court’s finding that the defendants
    breached the contract in bad faith. ‘‘[I]t is axiomatic
    that the . . . duty of good faith and fair dealing is a
    covenant implied into a contract or a contractual rela-
    tionship. . . . In other words, every contract carries
    an implied duty requiring that neither party do anything
    that will injure the right of the other to receive the
    benefits of the agreement. . . . The covenant of good
    faith and fair dealing presupposes that the terms and
    purpose of the contract are agreed upon by the parties
    and that what is in dispute is a party’s discretionary
    application or interpretation of a contract term. . . .
    To constitute a breach of [the implied covenant of good
    faith and fair dealing], the acts by which a defendant
    allegedly impedes the plaintiff’s right to receive benefits
    that he or she reasonably expected to receive under the
    contract must have been taken in bad faith.’’ (Internal
    quotation marks omitted.) Renaissance Management

    ‘‘Bad faith in general implies both actual or construc-
    tive fraud, or a design to mislead or deceive another,
    or a neglect or refusal to fulfill some duty or some
    contractual obligation, not prompted by an honest mis-
    take as to one’s rights or duties, but by some interested
    or sinister motive.’’ (Internal quotation marks omitted.)

    ,

    (2009). ‘‘Whether a party has acted in bad faith is a
    question of fact, subject to the clearly erroneous stan-
    dard of review.’’ Harley v. Indian Spring Land Co.,
    
    123 Conn. App. 800
    , 837, 
    3 A.3d 992
     (2010).
    First, we note that the facts supporting the court’s
    conclusion that Aferzon acted in bad faith in breaching
    the agreement are not subject to the three year statute
    of limitations for CUTPA claims. The three year statute
    of limitations applies to the particular conduct that
    the court found to constitute unfair trade practices in
    violation of CUTPA, not to the subordinate factual find-
    ings supporting its conclusion that when Aferzon
    engaged in such conduct he was acting in bad faith.
    They are separate determinations. As we have
    explained, a number of the defendants’ bad faith
    breaches of contract occurred within the three year
    limitation period, and each successive breach occurred
    in the course of and in furtherance of the same bad
    faith scheme.
    On the basis of our review of the record, we conclude
    that the court’s finding that Aferzon breached the agree-
    ment in bad faith is supported by the evidence. The
    court explained that Aferzon lied about the status of the
    project, ignored the plaintiff’s requests for information,
    disregarded letters from the plaintiff’s counsel, created
    ISI as a way to get around the agreement, and attempted
    to fabricate expenses during litigation. There is support
    for each of these findings in the record. Therefore, it
    was not clearly erroneous for the court to conclude
    that Aferzon’s repeated breaches of the agreement after
    engaging in such conduct were made in bad faith.
    We next consider the court’s subsequent conclusion
    that the defendants’ bad faith breaches of the agreement
    constituted CUTPA violations. We iterate that a trial
    court’s decision as to whether a defendant’s acts consti-
    tute deceptive or unfair trade practices in violation of
    CUTPA is a question of fact that we review for clear
    error. Landmark Investment Group, LLC v. Chung
    Family Realty Partnership, LLC, supra, 
    125 Conn. App. 699
    –708.
    The court’s conclusion that the defendants commit-
    ted unfair trade practices was not clearly erroneous.
    Breaches of contract can constitute CUTPA violations
    when found to have been committed in aggravating
    circumstances, with unscrupulous conduct, or in bad
    faith. See Ulbrich v. Groth, supra, 
    310 Conn. 410
    ; Land-
    mark Investment Group, LLC v. Chung Family Realty
    Partnership, LLC, supra, 
    125 Conn. App. 708
    . The
    defendants breached the agreement thirteen times
    within the applicable limitation period, and the court
    listed several aggravating circumstances, for which we
    have found support in the record, supporting its conclu-
    sion that these breaches were made in bad faith. In
    Landmark Investment Group, LLC, this court explained
    that even a single act of misconduct can constitute a
    CUTPA violation. See Landmark Investment Group,
    LLC v. Chung Family Realty Partnership, LLC, supra,
    708.
    Therefore, we affirm the court’s finding of a CUTPA
    violation and its decision to award the plaintiff its attor-
    ney’s fees. Because, however, the court engaged in no
    discussion of the applicable statute of limitations, and
    several breaches on which it did rely in finding such a
    violation occurred outside of the three year limitation
    period, we must remand the case to the court with
    instructions to determine, if possible, what portion of
    the fees and costs it awarded under CUTPA were rea-
    sonably incurred to litigate that portion of the CUTPA
    claim that was not barred by the statute of limitations.
    The court should consider only the time spent litigating
    and establishing the breaches for which a recovery is
    permissible under CUTPA and the time spent establish-
    ing the factual basis for its finding that such actionable
    breaches were committed in bad faith. We recognize
    that it may be impracticable for the court to apportion
    the fees in this fashion; see Total Recycling Services
    of Connecticut, Inc. v. Connecticut Oil Recycling Ser-
    vices, LLC, 
    308 Conn. 312
    , 333, 
    63 A.3d 896
     (2013)
    (‘‘when certain claims provide for a party’s recovery of
    contractual attorney’s fees but others do not, a party
    is nevertheless entitled to a full recovery of reasonable
    attorney’s fees if an apportionment is impracticable
    because the claims arise from a common factual

     (2006); but, this is not something that we can deter-
    mine in the first instance on appeal. There may be some
    portion of the attorney’s time that was definitively spent
    on violations occurring outside of the limitation period,
    for example, any time spent determining or litigating
    the cash value of the Alphatec stock transfer, which
    occurred in 2010, outside of the limitation period for
    CUTPA claims. Accordingly, we remand this case to the
    trial court with instructions to determine the amount
    of attorney’s fees and costs that the plaintiff is entitled
    to recover, limited to those fees and costs reasonably
    incurred to prosecute the portion of its claim under
    CUTPA that was based on the defendants’ bad faith
    breaches of the parties’ contract within the three year
    limitation period applicable to such claims under § 42-
    110g (f).
    II
    THE PLAINTIFF’S CROSS APPEAL
    The plaintiff cross appeals from the court’s award of
    offer of compromise interest. The plaintiff argues that
    the court committed multiple errors in its calculation
    of the amount of interest to which it is entitled based
    on the defendants’ failure to accept its offer of compro-
    mise. The defendants have not filed an answering brief
    on the plaintiff’s cross appeal. We agree with the plain-
    tiff that the court erred in determining the amount of
    offer of compromise interest to which it was entitled
    in this case, and thus reverse the court’s judgment with
    respect to that issue and remand this case with instruc-
    tions to recalculate its award of offer of compromise
    in a manner consistent with this opinion.
    The following additional facts and procedural history
    are relevant to this issue. On October 10, 2019, the
    plaintiff filed a unified offer of compromise pursuant
    to § 52-192a, offering to settle its claims against the
    defendants for $1,150,000.23 The parties do not dispute
    that the offer was appropriately made more than 180
    days after the defendants were served with legal pro-
    cess in this action, more than 30 days prior to the first
    day of trial and within 18 months of the filing of the
    complaint. The defendants did not accept the offer. On
    April 22, 2020, the court rendered judgment for the
    plaintiff, ultimately awarding it $1,587,289 in expecta-
    tion damages on its breach of contract claim, prejudg-
    ment interest in the amount of $504,054 under § 37-3a,
    and $756,000 in expenses and attorney’s fees under
    CUTPA. On May 21, 2020, the plaintiff moved for the
    court to award offer of compromise interest, claiming
    ‘‘[the plaintiff] is entitled to mandatory offer of compro-
    mise interest at the rate of 8 percent per year on the
    total of (1) [the plaintiff’s] expectation damages, (2)
    prejudgment interest and (3) attorney’s fees and
    expenses awarded, calculated from July 19, 201824 (the
    date [the plaintiff] filed its complaint) through the date
    this court enters final judgment.’’ (Footnote added.)
    The court rendered final judgment for the plaintiff
    on September 21, 2020, awarding it $90,968.00 in offer of
    compromise interest. Before explaining its calculations,
    the court expressed its concern that the offer of com-
    promise interest it awarded would be too severe: ‘‘The
    court is concerned that the 8 percent interest rate dic-
    tated by the offer of compromise statute is today
    extraordinary. It is a penalty whose severity has mark-
    edly increased. . . . The idea is to provide compensa-
    tion for the wrongful detention of the money and a
    significant but not draconian consequence for failing
    to accept the offer of compromise.’’ To address these
    concerns, the court deviated from the statutory lan-
    guage of § 52-192a in three ways. First, it awarded the
    plaintiff interest on the difference between the amount
    it recovered in the action and the amount of the settle-
    ment proposed in the offer of compromise, rather than
    on the total amount of the plaintiff’s recovery. Second,
    the court did not include its award of prejudgment
    interest to the plaintiff under § 37-3a in the total amount
    of the court’s award of money damages for the purpose
    of calculating the amount of offer of compromise inter-
    est it should award.25 Third, not wanting to award ‘‘inter-
    est on the interest,’’ the court subtracted 4.5 percent,
    representing the interest it had already awarded to the
    plaintiff under § 37-3a, from the 8 percent interest rate
    established by statute for the calculation of offer of
    compromise interest in § 52-192a, and thus applied an
    interest rate of 3.5 percent when calculating the amount
    of the plaintiff’s offer of compromise award. Ultimately,
    applying a 3.5 percent annual interest rate to the
    reduced sum of $1,193,289, which did not include the
    prejudgment interest it had awarded to the plaintiff,
    the court awarded the plaintiff a total of $90,968 in offer
    of compromise interest.
    Each of the three adjustments detailed previously
    was improper. We address each in turn, but first set
    forth our standard of review. ‘‘[The purpose of § 52-
    192a] is to encourage pretrial settlements and, conse-
    quently, to conserve judicial resources. . . . [T]he
    strong public policy favoring the pretrial resolution of
    disputes . . . is substantially furthered by encouraging
    defendants to accept reasonable offers of judg-
    ment.26. . . Section 52-192a encourages fair and reason-
    able compromise between litigants by penalizing a party
    that fails to accept a reasonable offer of settlement.
    . . . In other words, interest awarded under § 52-192a
    is solely related to a defendant’s rejection of an advanta-
    geous offer to settle before trial and his subsequent
    waste of judicial resources.’’ (Citations omitted; foot-

     (1997). ‘‘The
    question of whether the trial court properly awarded
    interest pursuant to § 52-192a is one of law subject to
    de novo review. . . . It is well established that [§] 52-
    192a provides for interest until the date of judgment.
    . . . Section 52-192a (b) requires a trial court to award
    interest to the prevailing plaintiff from the date of the
    filing of a complaint to the date of judgment whenever:
    (1) a plaintiff files a valid offer of judgment within
    eighteen months of the filing of the complaint in a civil
    complaint for money damages; (2) the defendant rejects
    the offer of judgment; and (3) the plaintiff ultimately
    recovers an amount greater than or equal to the offer of
    judgment.’’ (Citations omitted; internal quotation marks

     (1990).
    We first address the court’s decision to apply the
    interest rate to the difference between the amount
    recovered by the plaintiff and the amount of the settle-
    ment proposed in the offer of compromise, rather than
    to the total amount recovered by the plaintiff. Section
    52-192a (c) expressly provides that ‘‘the court shall
    add to the amount so recovered eight per cent annual
    interest on said amount.’’ (Emphasis added.) The stat-
    ute further sets forth, however, that in the case of a
    counterclaim plaintiff under General Statutes § 8-132,
    the court ‘‘shall add to the amount so recovered eight
    per cent annual interest on the difference between the
    amount so recovered and the sum certain specified
    in the counterclaim plaintiff’s offer of compromise.’’
    (Emphasis added.) General Statutes § 52-192a (c).
    Under the statute, the court must calculate interest on
    the difference only when the offer of compromise was
    filed by a counterclaim plaintiff under § 8-132. The plain-
    tiff is not a counterclaim plaintiff. The statute mandates
    that the court apply offer of compromise interest ‘‘on
    the amount so recovered.’’ ‘‘[B]ased upon the statutory
    language of § 52-192a, it [would be] plain error for the
    trial court to compute interest only on a portion of the
    award. . . . The plain language of . . . § 52-192a
    specifies that the court shall add to the amount so
    recovered [8] percent annual interest on said amount.
    . . . The trial court clearly did not act in accordance
    with the mandate of § 52-192a when it awarded interest
    only on the damages portion of the award. . . . [I]nter-
    est must be awarded on the entire award, that is, the
    amount so recovered.’’ (Citations omitted; emphasis in
    original; internal quotation marks omitted.) Gillis v.

     (1990); see also Cardenas
    v. Mixcus, 
    264 Conn. 314
    , 323, 
    823 A.2d 321
     (2003)
    (holding that offer of compromise interest must be cal-
    culated on total amount of jury verdict rather than
    amount remaining after apportionment to employer to
    satisfy amount it had paid plaintiff as workers’ compen-
    sation benefits). It was error for the court to calculate
    the plaintiff’s award of offer of compromise interest on
    the basis of the difference between the amount of its
    recovery and the amount of its offer of compromise.
    We next address the court’s failure to include the
    prejudgment interest awarded under § 37-3a in the
    plaintiff’s total recovery when calculating its award of
    offer of compromise interest. This court has explicitly
    held that an award under § 37-3a must be included in
    the calculation of interest awarded under § 52-192a.
    ‘‘Unlike § 37-3a, § 52-192a does not depend on an analy-
    sis of the underlying circumstances of the case or a
    determination of the facts. Section 52-192a applies only
    to civil actions on contracts or for the recovery of
    money. Wrongful detention of money need not be found.
    The interest awarded is in no way discretionary. The
    statute provides that the court shall examine the record
    after trial, and if the plaintiff’s recovery exceeds the
    rejected offer of judgment found in the record, the court
    shall add interest to that recovery. In an appropriate
    case, both statutes could apply; the defendant could
    owe interest as damages on the debt and then owe
    interest on the total amount based on his refusal to
    settle.’’ (Emphasis altered.) Paine Webber Jackson &
    Curtis, Inc. v. Winters, supra, 
    22 Conn. App. 653
    . An
    offer of compromise, like the offer of judgment that
    preceded it, is ‘‘an offer to settle the entire case, includ-
    ing claims both known and unknown, and both certain
    and uncertain. . . . In addition to money saved by
    avoiding litigation expenses, a defendant might also
    save the discretionary interest of § 37-3a. A defendant
    must assess the degree of possibility that interest may
    be awarded in the event that the trier determines that
    money has been detained by a defendant after it became
    due. The defendants here risked that a judgment would
    not include § 37-3a interest. The vagaries of the compo-
    nents of settlement include a possibility that § 37-3a
    interest will be awarded in some cases. In the present
    case, the possibility became reality.’’ (Citation omitted;
    internal quotation marks omitted.) Flynn v. Kaumeyer,
    
    67 Conn. App. 100
    , 107–108, 
    787 A.2d 37
     (2001); see
    also Gillis v. Gillis, supra, 
    21 Conn. App. 556
     (finding
    that prejudgment interest awarded under § 37-3a must
    be included in total amount recovered when calculating
    offer of judgment interest). Therefore, interest must
    be awarded on the total amount recovered, including
    prejudgment interest.
    Lastly, we discuss the court’s reduction of the per-
    centage of the plaintiff’s recovery awarded as offer of
    compromise interest. ‘‘[Section] 52-192a provides for
    mandatory imposition of interest at a set rate, unlike
    § 37-3a . . . and affords no allowance for the discre-
    tion of the court. (Citation omitted; emphasis in origi-
    nal.) Ceci Bros., Inc. v. Five Twenty-One Corp.,

    268 Conn. 922

     (2004). As we have stated, ‘‘[t]he interest
    awarded is in no way discretionary.’’ Paine Webber
    Jackson & Curtis, Inc. v. Winters, supra, 
    22 Conn. App. 653
    . A comparison between §§ 37-3a and 52-192a
    informs our conclusion. Section 37-3a provides that
    ‘‘interest at the rate of ten per cent a year, and no more,
    may be recovered and allowed in civil actions . . . as
    damages for the detention of money after it becomes
    payable.’’ (Emphasis added.) This statute gives trial
    courts the discretion to decide whether to award pre-
    judgment interest at all and the rate to apply. See Riley
    v. Travelers Home & Marine Ins. Co., 
    173 Conn. App. 422
    , 461–62, 
    163 A.3d 1246
     (2017), aff’d, 
    333 Conn. 60
    ,
    
    214 A.3d 345
     (2019). By contrast, § 52-192a provides
    that ‘‘the court shall add to the amount so recovered
    eight per cent annual interest on said amount . . . .’’
    (Emphasis added.) Unlike § 37-3a, which establishes 10
    percent as an optional maximum, § 52-192a states that
    the court shall apply 8 percent. Our Supreme Court has
    stated that use of the word shall generally evidences
    an intent that the statute be interpreted as mandatory;
    see, e.g., DeMayo v. Quinn, 
    315 Conn. 37
    , 43, 
    105 A.3d 141
     (2014); and, indeed, this court has consistently inter-
    preted § 52-192 as mandatory. See, e.g., Ceci Bros., Inc.
    v. Five Twenty-One Corp., supra, 430. It was improper
    for the court to calculate the offer of compromise award
    at the reduced rate of 3.5 percent per year instead of
    at the mandatory statutory rate of 8 percent per year.
    Accordingly, on the plaintiff’s cross appeal, we
    reverse the court’s judgment awarding offer of compro-
    mise interest to the plaintiff and remand this case to the
    trial court with instructions to recalculate the amount
    of that award in a manner consistent with this opinion
    after determining the amount of attorney’s fees and
    costs to which the plaintiff is entitled under CUTPA
    and adding that amount to the plaintiff’s adjusted total
    damages for breach of contract.
    The judgment is reversed only with respect to the
    determination that the statute of limitations was tolled
    as to the plaintiff’s breach of contract claim, the amount
    of damages awarded on the plaintiff’s breach of contract
    claim, the amount of attorney’s fees and costs awarded
    on the plaintiff’s CUTPA claim, and the amount of the
    award of offer of compromise interest, and the case is
    remanded with direction (1) to render judgment in favor
    of the plaintiff on the breach of contract claim in the
    modified amount of $1,204,968.41, (2) to determine, if
    possible, the amount of attorney’s fees and costs that
    were reasonably incurred by the plaintiff to prosecute
    that portion of its CUTPA claim that was based on unfair
    trade practices committed by the defendants within
    the three year statute of limitations applicable to such
    claims, and (3) to recalculate the award of offer of
    compromise interest in a manner consistent with this
    opinion, after determining the amount of attorney’s fees
    and costs to be awarded on the plaintiff’s CUTPA claim
    and recalculating the total amount of the plaintiff’s
    recovery herein; the judgment is affirmed in all other
    respects.
    In this opinion the other judges concurred.
    1
    There was some dispute between the parties as to what was expected
    of MDS under their oral agreement. Lyons and Young testified that their
    obligation was to ‘‘develop and manufacture a prototype,’’ but Aferzon
    ‘‘insist[ed] there was more,’’ claiming that he expected MDS to produce
    something ‘‘functional, reproducible, and manufacturable.’’ It was undis-
    puted, however, that MDS, at a minimum, had agreed to prepare design
    drawings and produce a prototype of the device.
    2
    A pinion is ‘‘a gear with a small number of teeth designed to mesh with
    a larger wheel or rack.’’ Merriam-Webster’s Collegiate Dictionary (11th Ed.
    2014) p. 941.
    3
    The court ‘‘consider[ed] the stock to have a cash value on its date of
    transfer that [was] the dollar value at a per share value judicially noticed
    by the court and that MDS used in its damage calculation.’’ This valuation
    has not been challenged on appeal by either party.
    4
    The defendants also asserted waiver, that there was reliance or perfor-
    mance on the part of the plaintiff, laches, unclean hands, and that the plaintiff
    failed to mitigate its damages.
    5
    Additionally, the defendants argued before the court that development
    expenses of a ‘‘lateral’’ device should also reduce the total compensation
    received. As the court explained, ‘‘[a] ‘lateral’ device goes into the body
    from the side. An ‘anterior’ device is inserted into the body through the
    front.’’ Although Aferzon and Bash also patented a lateral device and assigned
    it to ISI, they did not license the lateral device to Alphatec, Alphatec never
    sold lateral devices, and the defendants never made money from the sale
    and/or licensing of that device. The court held that the parties’ agreement
    covered only the anterior device and did not consider the development
    expenses of the lateral device, explaining that any expenses related to the
    lateral device were irrelevant. This ruling has not been challenged on appeal.
    Thus, any references to the ‘‘device’’ or the ‘‘patented device’’ throughout
    this opinion refer only to the anterior device.
    6
    The defendants have not challenged on appeal the finding of successor
    liability or the court’s conclusion that the defendants’ calculation of expenses
    was not reliable.
    7
    The court also considered, and denied, the defendants’ special defenses
    of unconscionability and mistake. These rulings have not been challenged
    on appeal.
    8
    The court does not explain why it initially calculated the amount of
    prejudgment interest to which the plaintiff was entitled under § 37-3a until
    May 4, 2020, even though it issued its memorandum of decision rendering
    partial judgment for the plaintiff on April 22, 2020. In the end, however, the
    court’s initial selection of that end date for its calculation of prejudgment
    interest is of no significance because the court later extended the end
    date of its interest calculation until September 21, 2020, the date of final
    judgment herein.
    9
    The court also suggested, as follows, that it might be awarding attorney’s
    fees both under the common law and under CUTPA: ‘‘It’s worth noting that
    the court would award attorney’s fees even without CUTPA.’’ So understand-
    ing the court’s ruling, the parties briefed the propriety of such an award
    before this court. The trial court, however, issued a supplemental order on
    October 16, 2020, clarifying that it did not award fees under the common
    law. Accordingly, that issue is not before this court.
    10
    Specifically, the defendants request that the issue should be remanded
    for the agreement to be reinterpreted based on its plain language: ‘‘The
    defendants are not challenging the trial court’s factual findings but, rather,
    whether those findings are legally material to the fundamental question at
    hand: is the [patent] within the scope of the November 4, 2004 agreement?
    The defendants are entitled to a legal analysis that matches the terms of
    the contract. The trial court misinterpreted the contract, and, therefore, its
    factual findings do not add up to its conclusion of legal liability.’’
    11
    As mentioned previously, the defendants also argued that the plaintiff
    was barred from recovering because the profits went to a limited liability
    company and that they were negated by expenses. The court rejected both
    of these arguments, and they have not been advanced on appeal.

    The court stated: ‘‘All we have to do to see the relationship is to look
    at the drawings beginning with Aferzon’s and ending with those in the patent
    application to see that they are at minimum the same basic idea . . . .’’
    16
    Aferzon testified that he did not recall receiving these letters or the
    2008 e-mails. The court did not find this claim credible and presumed that
    they arrived. The defendants have not challenged this finding.
    17
    The court explained that ‘‘the [plaintiff] first learned what it needed to
    know to sue, at the earliest, in the late fall of 2017 when [the plaintiff’s]
    CEO Lyons was told by his physical therapist that the device was making
    money and that Bash—whom Lyons knew to be associated with Aferzon—
    was training physicians about how to use it.’’ The letters were sent on
    November 24, 2017, and February 6, 2018. We note that the first letter also
    states that ‘‘your conduct appears to constitute a breach of the [a]gree-
    ment . . . .’’
    18
    The court, in its discussion of the continuing course of conduct doctrine,
    characterized the relationship between the parties as a ‘‘special relationship’’
    that was akin to a fiduciary relationship, arising from a ‘‘specific, legally
    recognized duty in contract that was continuing and required Aferzon to
    report his gains from the device idea to [the plaintiff].’’ The plaintiff now
    argues that this relationship is ‘‘functionally equivalent to the duty to disclose
    arising out of a fiduciary relationship . . . .’’ For the reasons discussed in
    part I C 2 of this opinion, the court overstates the nature of the parties’
    relationship and, thus, this conclusion has no bearing on whether fraudulent
    concealment applies to the defendants’ actions.
    The plaintiff argues that the court should decide on remand whether the
    parties had a fiduciary relationship, but, as we explain in part I C 2 of this
    opinion, there is insufficient evidence for a special relationship, and the
    court was not able to point to any factors that would give rise to a special
    relationship. It would be fruitless to consider the issue on remand.
    19
    We do not fault the court for its use of both terms, as our Supreme
    Court indicated in Bouchard that, until recently, our courts have used the
    terms in a manner that would imply that they are interchangeable. See
    Bouchard v. State Employees Retirement Commission, supra, 
    328 Conn. 374
     n.14. The trial court also noted the distinction at first, explaining that
    ‘‘[s]ometimes this idea of multiple breaches is called a continuing violation
    under the label of a ‘separate accrual rule.’ Other times, tolling is allowed
    under a version of this doctrine recognizing a series of acts as one long
    wrong that keeps going until the last wrong act, tolling the limitation period
    for everything from the first act to the last.’’ Nevertheless, the court failed
    to distinguish the two in its analysis.
    20
    The plaintiff takes issue with the defendants’ citation of this passage,
    arguing that the ‘‘defendants incorrectly quote inapposite dicta in [Watts v.
    Chittenden, supra, 
    301 Conn. 588
    ], regarding ‘discrete injuries . . . in suits
    for lost wages’ as if it were a statement of Connecticut law by the Connecticut
    Supreme Court. . . . In reality, that statement is a quotation attributable
    to the Seventh Circuit’s decision in Heard v. Sheahan, 
    253 F.3d 316
    , 320
    (7th Cir. 2001), which, in turn, was citing the Eleventh Circuit decision
    of Knight v. Columbus, 
    [supra,
     
    19 F.3d 581
    –82], discussing whether the
    ‘continuing violation theory’ was applicable to a violation of the Fair Labor
    Standards Act. [
    29 U.S.C. § 201
     et seq.] Importantly, the ‘continuing violation
    theory’ is not the same as the ‘continuing course of conduct doctrine.’ ’’
    (Citation omitted.) The plaintiff is correct that these two cases discuss
    ‘‘continuing violations’’ but, as our Supreme Court has stated, the terms
    have been used interchangeably; Bouchard v. State Employees Retirement
    Commission, supra, 
    328 Conn. 374
     n.14; and it is clear that these cases
    discuss what our courts refer to as a continuing course of conduct: ‘‘The
    term ‘continuing violation’ also implies that there is but one incessant viola-
    tion and that the [plaintiff] should be able to recover for the entire duration
    of the violation, without regard to the fact that it began outside the statute
    of limitations window. That is not the case. Instead of one [ongoing] violation,
    this case involves a series of repeated violations of an identical nature.
    Because each violation gives rise to a new cause of action, each failure to
    pay overtime begins a new statute of limitations period as to that particular
    event.’’ Knight v. Columbus, 
    supra, 582
    .
    Regardless of the terminology used by the courts in Knight and Heard,
    our Supreme Court clearly cited the passage as an example of what would
    not qualify as a continuing course of conduct. Watts v. Chittenden, supra,
    
    301 Conn. 587
    –90. To argue that the passage is not Connecticut law because
    it was ultimately derived from federal cases is inaccurate, especially consid-
    ering that the passage has since been cited in other Connecticut cases
    discussing the continuing course of conduct doctrine. See, e.g., Saint Ber-
    nard School of Montville, Inc. v. Bank of America, supra, 
    312 Conn. 838
    .
    21
    In so doing, we note that if the plaintiff’s adjusted recovery falls below
    the amount of its unified offer of compromise pursuant to § 52-192a, the
    plaintiff’s cross appeal would be rendered moot.
    22
    The defendants did plead in their answer that the plaintiff’s claims were
    barred by the statute of limitations set forth in § 42-110g.
    23
    General Statutes § 52-192a provides in relevant part: ‘‘(a) Except as
    provided in subsection (b) of this section, after commencement of any civil
    action based upon contract or seeking the recovery of money damages,
    whether or not other relief is sought, the plaintiff may, not earlier than one
    hundred eighty days after service of process is made upon the defendant
    in such action but not later than thirty days before trial, file with the clerk
    of the court a written offer of compromise signed by the plaintiff or the
    plaintiff’s attorney, directed to the defendant or the defendant’s attorney,
    offering to settle the claim underlying the action for a sum certain. For the
    purposes of this section, such plaintiff includes a counterclaim plaintiff
    under section 8-132. The plaintiff shall give notice of the offer of compromise
    to the defendant’s attorney or, if the defendant is not represented by an
    attorney, to the defendant himself or herself. Within thirty days after being
    notified of the filing of the offer of compromise and prior to the rendering
    of a verdict by the jury or an award by the court, the defendant or the
    defendant’s attorney may file with the clerk of the court a written acceptance
    of the offer of compromise agreeing to settle the claim underlying the action
    for the sum certain specified in the plaintiff’s offer of compromise. Upon
    such filing and the receipt by the plaintiff of such sum certain, the plaintiff
    shall file a withdrawal of the action with the clerk and the clerk shall record
    the withdrawal of the action against the defendant accordingly. If the offer
    of compromise is not accepted within thirty days and prior to the rendering
    of a verdict by the jury or an award by the court, the offer of compromise
    shall be considered rejected and not subject to acceptance unless refiled.
    Any such offer of compromise and any acceptance of the offer of compro-
    mise shall be included by the clerk in the record of the case. . . .
    ‘‘(c) After trial the court shall examine the record to determine whether
    the plaintiff made an offer of compromise which the defendant failed to
    accept. If the court ascertains from the record that the plaintiff has recovered
    an amount equal to or greater than the sum certain specified in the plaintiff’s
    offer of compromise, the court shall add to the amount so recovered eight
    per cent annual interest on said amount, except in the case of a counterclaim
    plaintiff under section 8-132, the court shall add to the amount so recovered
    eight per cent annual interest on the difference between the amount so
    recovered and the sum certain specified in the counterclaim plaintiff’s offer
    of compromise. The interest shall be computed from the date the complaint
    in the civil action or application under section 8-132 was filed with the court
    if the offer of compromise was filed not later than eighteen months from
    the filing of such complaint or application. If such offer was filed later than
    eighteen months from the date of filing of the complaint or application, the
    interest shall be computed from the date the offer of compromise was filed.
    The court may award reasonable attorney’s fees in an amount not to exceed
    three hundred fifty dollars, and shall render judgment accordingly. This
    section shall not be interpreted to abrogate the contractual rights of any
    party concerning the recovery of attorney’s fees in accordance with the
    provisions of any written contract between the parties to the action.’’
    24
    Section 52-192a specifies that the interest should be calculated from
    the date the complaint was filed. The court appropriately used this date.
    25
    The court stated: ‘‘To make this adjustment, for purposes of the offer
    of compromise statute, the court treats as the amount recovered the damages
    award in the amount of $1,587,289 and the attorney’s fee award of $756,000
    for a total recovery of $2,343,289. The offer of compromise was for
    $1,150,000. The extra amount recovered gets the 8 percent rate. It is derived
    by subtracting from the total recovery of $2,343,289 the $1,150,000 offer of
    compromise amount yielding an amount in excess of the offer of $1,193,289.’’
    26
    We note that § 52-192a was amended in 2005 by, inter alia, the substitu-
    tion of ‘‘offer of compromise’’ for ‘‘offer of judgment’’ and other technical
    changes. See Public Acts 2005, No. 05-275, § 4. The general function of the
    statute remains the same and, thus, case law from before the amendment
    is still applicable. See, e.g., Georges v. OB-GYN Services, P.C., 
    335 Conn. 669
    , 680–81, 
    240 A.3d 249
     (2020) (applying case law that predates amendment
    in discussion concerning offer of compromise interest).
