OPINION OF THE COURT
This is аn appeal from orders entered by the District Court after a trial concerning the right to use the mark “The Drifters” for a singing group. Larry Marshak, who acquired a federally registered service mark for “The Drifters” name in 1978, brought this action against Faye Treadwell and others, claiming that they were infringing his mark. The defendants contended that Marshak’s federally registered mark had been procured by fraud and that Marshak was infringing senior common-law rights. After a trial and post-trial motions, the District Court ordered that Marshak’s federally registered mark be canceled, permanently enjoined Marshak from using the mark in commerce, and required an accounting of all profits received by Marshak since he began using the mark. Marshak then took this appeal. We affirm in part and dismiss in part for lack of appellate jurisdiction.
I.
The Drifters were one of the classic popular singing groups of the 1950s and early 1960s. Among their well-known hits were “Under the Boаrdwalk,” “On Broadway,” and “Save the Last Dance for Me.”
The Drifters first appeared in 1953 and came under the management of George Treadwell the following year. From then until his death in 1967, George Treadwell managed the group through The Drifters, Inc., a New York corporation that he formed. George Treadwell hired and paid salaries to the members of the group, who changed continually over the years. He also scheduled the group’s performances, negotiated their recording contracts, and chose their music and arrangements.
*188 In 1959, George Treadwell released all of the then-current members of the group and signed the former members of a group called the Five Crowns to perform as, The Drifters. The new members included Charlie Thomas, Elsbeary Hobbs, and Dock Green. Like all other members of the Drifters, Thomas, Hobbs, and Green signed contracts that provided in pertinent part as follows:
The Artist agrees that the name THE DRIFTERS belongs exclusively to the employer and that he will not at any time use the name of The Drifters or any name similar thereto or any name incorporating The Drifters. In the event the employee leaves the employ of The Drifters he will not in any way advertise or attempt to publicize the fact that he had been a member of a singing group known as The Drifters and will not associate his name in any manner with The Drifters; and he further acknowledges that the name, The Drifters, is a valuable property and any violation of this paragraph could not be adequately compensated by money damages and he therefore agrees that the employer shall be entitled to an injunction in any Court of competent jurisdiction to enjoin any violation or threatened violation of the contract by the Artist.
App. at 1264.
When George Treadwell died, his wife, Faye Treadwell, whom he married in 1955, became the sole shаreholder of The Drifters, Inc., and she took over the management of the group. She later formed Treadwell’s Drifters, Inc., a New Jersey corporation, and all of the assets and contractual rights of The Drifters, Inc. were transferred to the new corporation.
By the time of George Treadwell’s death, Hobbs and Green had already left the group. Charlie Thomas left shortly thereafter, but other members continued to perform under Treadwell’s direction. By the late 1960s, however, the popularity of “The Drifters” and similar groups had waned in this country, and Treadwell focused her efforts on. Europe, where the group remained popular. After 1970, the Drifters made few live appearances in this country, but the group’s classic recordings continued to be played on the radio, and Atlantic Records continued to pay royalties to The Drifters, Inc. or Treadwell’s Drifters, Inc. See App. at 720.
Larry Marshak’s involvement with The Drifters began in 1969. CBS radio had recently changed from a contemporary to an “oldies” format. To generate enthusiasm for its format change, CBS approached Rock Magazine and proposed a partnership to reunite old singing groups to perform live concerts. Marshak, who was an editor at Rock Magazine, was given the task of reuniting some of these groups for the first revival concert at the New York Academy of Music. Among the groups that Marshak attempted to reunite was “The Drifters.” Marshak contacted several former members of the group, including Thomas, Hobbs, and Green, all of whom agreed to perform for Marshak. The revival concerts were a success, and the reunited members agreed to continue performing under “The Drifters” name. In 1972, Thomas, Hobbs, and Green signed an exclusive management contract with Marshak.
Soon after the revival group began performing, Marshak received a letter from Treadwell’s attorney asserting that Mars-hak was infringing her right to use the group’s name. App. at 244. The letter pointed out that the former members of the group had signed contracts with The Drifters, Inc. in which they had given up any right to use the group name. Id. Despite this warning, Marshak persisted in his efforts to promote and market his group.
In 1971, Treadwell brought an action against Marshak in state court in New York. Treadwell’s request for a preliminary injunction to prevent Marshak and his group from using “The Drifters” name was denied, and the suit was eventually *189 dismissed in 1973 because Treadwell “willfully defaulted and failed to answer interrogatories propounded by defendants.” App. at 1245. At the trial in the current case, Treadwell testified that she and her group stopped performing in the United States in part because she did not have the financial resources to defend her mark against Marshak through extended litigation. See App. at 598.
Marshak, in contrast, benefitted from a renewed interest in “The Drifters” in the United Stаtes that had resulted from a wave of nostalgia for the early days of rock and roll. Throughout the 1970s, Mars-hak’s group made recordings, appeared on television, and gave live performances.
Marshak began to litigate against other groups that used the name “The Drifters” or a variant. In 1976, Marshak learned that “The Platters,” another revived 1950s singing group, had been successful in preventing others from using their name by registering their service mark, and Mars-hak urged Thomas, Hobbs, and Green to do the same. Marshak convinced the trio that if they agreed to assign their rights to the name to him, he would continue as their manager and prevent others groups from using “The Drifters” name. In December 1976, Thomas, Hobbs, and Green, acting as a partnership, filed an application with the United States Patent & Trademark Office (PTO) to register “The Drifters” as a service mark for a singing group, and they assigned their rights to Marshak. See App. at 1267. In their registration application, Thomas, Hobbs, and Green each attested that
no other person, firm, corporation, or association, to the best of his knowledge and belief, has the right to use such mark in commerce either in the identical form thereof or in such near resemblance thereto as to be likely, when applied to the goods of such other person, to cause confusion, or to cause mistake, or deceive.
See 15 U.S.C. § 1051 (1976).
Marshak filed the present action in 1995, following the publication of Faye Tread-well’s book, Save the Last Dance for Me, in which Treadwell claimed to be the sole owner of the Drifters mark. See App. at 875. Named as defendants were Faye Treadwell, The Drifters, Inc., Treadwell’s Drifters, Inc., and a booking company. Marshak alleged that the defendants had infringed his mark and had threatened to continue to do so by offering Treadwell’s book for sale and by engaging a group to perform as The Drifters. He asserted a clаim under Section 32 of the Lanham Act, 15 U.S.C. § 1114(a), for infringement of his federally registered mark, as well as a claim under Section 43(a), 15 U.S.C. § 1125(a), and under the statutes of New York for violation of his common-law rights. He sought declaratory and injunc-tive relief and treble and punitive damages.
In their answer, the defendants claimed that Treadwell’s Drifters had a superior common-law right to the mark, and they asserted as an affirmative defense that Marshak’s federal registration had been procured by fraud. As a counterclaim, Treadwell’s Drifters repeated the allegation of fraudulent procurement. In addition, alleging that Marshak had infringed and continued to infringe its common-law right to the mark, Treadwell’s Drifters asserted a claim under Section 43(a) of the Lanham Act and a state-law claim for unfair competition. The counterclaim sought, among other things, cancellation of Mars-hak’s mark, declaratory and injunctive relief, and an acсounting of Marshak’s profits.
The case was tried before a jury, which found that Marshak or his assignors had perpetrated a fraud on the PTO in 1976. See App. at 1562. In accordance with this finding, the District Court ordered the PTO to cancel Marshak’s federal registration. The jury also found, however, that Treadwell and her corporation had abandoned their common-law right to “The Drifters” mark by 1976. Moreover, the *190 jury found that Marshak had established protectable common-law rights in the name by that time.
On cross post-trial motions, the District Court upheld the jury’s verdict regarding Marshak’s fraud on the PTO, but the Court vacated the jury verdict insofar as it found that Treadwell had abandoned her rights in 1976. Instead, the Court held that the continuous stream of royalty revenues collected by Treadwell since the 1960s was sufficient to defeat Marshak’s claim of abandonment.
See Marshak v. Treadwell,
II.
We begin by examining our jurisdiction to review the various orders challenged on appeal. Under 28 U.S.C. § 1292(a)(1), we plainly have jurisdiction to review the permanent injunction prohibiting Marshak from using The Drifters mark. Under
Santana Products, Inc. v. Compression Polymers, Inc.,
When we have jurisdiction to review an order relating to an injunction under § 1292(a)(1), our jurisdiction extends to matters inextricably linked to the appealable order.
See S.E.C. v. Black,
By contrast, we lack jurisdiction to review the portion of the District Court order requiring an accounting of Marshak’s profits. Marshak contends that we have jurisdiction under the final order rule of 28 U.S.C. § 1291, but we do not agree. A-final order is one that “leaves nothing for the court to dо but execute the judgment.”
Catlin v. United States,
Our decision in
Apex Fountain Sales, Inc. v. Kleinfeld,
In
Goodman v. Lee,
On appeal, the Fifth Circuit acknowledged a line of cases in which appeal had been permitted prior to a final accounting because the accounting was viewed as “purely ‘ministerial’ and/or ‘mechanical.’”
Id.
at 626 (citing
Winston Network v. Indiana Harbor Belt R. Co.,
The award contemplates identifying royalties paid on one particular song to songwriter now dead and thereafter to his heirs over an almost thirty (30) year period.... Cleаrly, the amount to be divided is not known, was not identified in the extensive district court experience and must be reconstructed requiring factual determinations by the district court.
Id. at 627. Therefore, the Court held that the judgment was not within the Forgay-Conrad rule and was not an • appealable final order. Id.
A similar result was reached in
Zwack v. Kraus Bros. & Co.,
In this case, as in the cases noted above, the accounting cannot reasonably be characterized as merely ministerial. The District Court ordered Marshak “to account to Treadwell for the profits he earned in each year, beginning with the first act of infringement in 1970 and ending with the first day of triаl testimony in this case.” App. at 87. As in
Apex Fountain Sales,
the parties here have a long history of contentious litigation, and there is a substantial likelihood that “one or both parties will dispute the ultimate amount of damages awarded, leading to a second appeal. This would be contrary to the federal judiciary’s general policy against piecemeal litigation.”
Apex Fountain Sales,
We are aware that the District Court, in denying Treadwell’s request that a special master be appointed, expressed the opinion that “the accounting will not be complicated or exceptional,” App. at 1687 n. 2, but that statement was made in a notably different context. An accounting may seem simple enough to persuade a District Court that the appointment of a special master is not necessary and still be far from ministerial in the sense relevant here. We must therefore dismiss Marshak’s appeal insofar as it contests the portion of *192 the district court order requiring an accounting. 1
III.
Turning to the merits of the issues over which we have jurisdiction, we first consider Marshak’s arguments relating to Tread-well’s fraudulent procurement defense and counterclaim.
A.
Marshak argues that the fraudulent procurement defense and counterclaim are time-barred. Relying chiefly on our decision in
Beauty Time, Inc. v. VU Skin Sys., Inc.,
Treadwell’s counterclaim was brought under Section 14 of the Lanham Act, 15 U.S.C. § 1064, which specifies in detail the time limits for petitioning to cancel a mark on various grounds. This provision states in relevant part:
A petition to cancel a registration of a mark, stating the grounds relied upon, may, upon payment of the prescribed fee, be filed as follows by any person who believes that he is or will be damaged ... by the registration of a mark on the principal register established by this chapter ...
(1) Within five years from the date of the registration of the mark under this chapter.
(2) Within five years from the date of publication under section 1062(c) of this title of a mark registered under the Act of March 3,1881, or the Act of February 20,1905.
(3) At any time if the registered mark becomes the generic name for the goods or services, or a portion thereof, for which it is registered, or has been abandoned, or its registration was obtained fraudulently or contrary to the provisions of section 1054 of this title or of subsection (a), (b), or (c) of section 1052 of this title for a registration under this chapter.
Lanham Act § 14, 15 U.S.C. § 1064 (emphasis added).
The first step in interpreting a statute is to determine “whether the language at issue has a plain and unambiguous meaning with regard to the particular dispute in the case.”
Robinson v. Shell Oil Co.,
Here, the meaning of the phrase “at any time” in Section 14(3) is clear even if that
*193
particular subsection is viewed in isolation. Moreover, the contrast between the five-year time limits imposed in subsections (1) and (2) and the use of the phrase “at any time” in subsection (3) reinforces the point that the language of subsection (3) means what it says: a petition falling within subsection (3), including a petition seeking cancellation based on fraud, is not subject to any time limit but may be filed “at any time.” We note that the Supreme Court has recognized that the predecessor of the current Section 14(3) “allows cancellation of an incontestable mark at any time
... if it was obtainеd fraudulently.” Park ‘N Fly, Inc. v. Dollar Park and Fly, Inc.,
We recognize that Section 14(3) itself applies to a petition filed with the Patent and Trademark Office, rather than a claim asserted in court, but Section 37 of the Lanham Act, 15 U.S.C. § 1119,
3
gives federal courts concurrent authority to cancel registered marks when the validity of the mark is called into question in a judicial proceeding.
See Ditri v. Coldwell Banker Residential Affiliates, Inc.,
The language of the Lanham Act also makes it clear that there is no time limit on the assertion of fraudulent procurement as a defense to an infringement claim brought by the holder of a mark that has become incontestable. Under Section 15 of the Lanham Act, 15 U.S.C. § 1065, an otherwise incontestable mark may be attacked “on a ground for which application to cancel may be filed at any time under paragraphs (3) and (5) of section 1064 of this title.” Accordingly, the language of the Lanham Act makes it clear that a claim for cancellation of a mark based on fraudulent procurement and a defense to an otherwise incontestable mark on a similar ground may be asserted at any time. 4
*194
The reason for this rule is quite simple — the interest vindicаted by Section 14 is not just the injury to the challenging party, but the integrity of the register. Where the interest at issue is the integrity of the federal register, a statute of limitations should not operate to frustrate that interest.
See Harjo v. Pro Football, Inc.,
Marshak’s only attempt to address the language of the Lanham Act permitting fraudulent procurement to be asserted in these contexts “at any time” appears in his reply brief, where he argues that this language merely reflects the fact that the grounds for cancellation covered by Section 14(3), such as a mark’s becoming generic, “are of a type in which the right to bring cancellation may arise ‘at any time’, i.e., some years (very possibly more that the five years of Section 1064(1)) after trademark registration.” Reply Br. at 4 (emphasis in original). Marshak suggests that once a plaintiff has become aware of the necessary predicate for bringing a cancellation proceeding, the plaintiff should be required to do so within the limitations period specified by the most analogous state statute.
Marshak’s argument cannot be reconciled with the plain language of Section 14(3), which, as noted, provides unambiguously that a petition seeking cancellation based on fraudulent procurement “may ... be filed” “at any time.” Marshak would read Section 14(3) as essentially a tolling provision, but the drafters of this provision would surely have selected different language if that is what they had intended. For all these reasons, we hold that Treadwell’s counterclaim and defense are not time-barred.
This holding is entirely consistent with our decision in Beauty Time, on which Marshak relies. In Beauty Time, count XI of the complaint asserted a claim under Section 38 of the Lanham Act, 15 U.S.C. § 1120, which provides as follows:
Any person who shall procure registration in the Patent and Trademark Office of a mark by a false or fraudulent declaration or representation, oral or in writing, or by any false means, shall bе hable in a civil action by any person injured thereby for any damages sustained in consequence thereof.
A claim for damages brought under Section 38 is not governed by any of the time limits set out in Section 14(3) or any other
*195
provision of the Act specifying a limitations period, and therefore we held that the plaintiffs Section 38 claim for fraud was subject to Pennsylvania’s two-year statute of limitations for actions based on fraud.
B.
Marshak argues that Treadwell’s fraudulent procurement defense and counterclaim were barred by principles of collateral estoppel. In the District Court, Marshak relied on several prior adjudications, but on appeal he focuses on
Marshak v. Sheppard,
The principle on which Marshak relies is aptly stated as follows in the Restatement (Second) of Judgments § 39:
A person who is not a party to an action but who controls or substantially participates in the control of the presentation on behalf of a party is bound by the determination of issues decided as though he were a party.
Comment c. adds:
To have control of litigation requires that a person have effective choice as to the legal theories and proofs to be advanced in behalf of the party to the action. He must also have control over the opportunity to obtain review.
*196
Cf.
Collins v. E.I. DuPont de Nemours & Co.,
Here, Marshak has not pointed to any direct evidence that Treadwell exercised any control over the prior litigation. Indeed, his brief notes only two concrete facts that are relevant: Treadwell testified in the prior case and had an interest in the outcome (in the sense that she would have benefitted if Marshak’s federally registered mark had been ordered canceled). Appellant’s Br. at 49. Without more, these facts are plainly insufficient to permit a reasonable inference that she exercised any control over litigation decisions or strategy. Marshak’s collateral estoppel argument must therefore be rejected.
C.
Marshak contends that the jury’s finding of fraud was based on an erroneous jury instruction, which stated that fraud on the PTO could be shown by proof that the applicants “should have known” about Treadwell’s superior right to “The Drifters” name. Although we agree with Mars-hak that this instruction was erroneous, we are convinced that the error was harmless.
Most of the District Court’s lengthy instruction on fraudulent intent is unobjectionable, 7 but at several points, the Court told the jury that “[t]he defense of fraud will turn upon whether you believe that the persons who registered the mark knew or reasonably should have known that someone else had legal rights to the name ‘The Drifters.’ ” App. at 1482-83 (emphasis added). Marshak objects that the “should have known” language misstates the nature of the PTO oath and the requisite measure of proof.
At the time when Thomas, Hobbs, and Green submitted their declaration, an applicant was required to state that
no other person, firm, corporation, or association, to the best of his knowledge and belief, has the right to use such mark in commerce either in the identical form thereof or in such near resemblance thereto as to be likely, when aрplied to the goods of such other person, to cause confusion, or to cause mistake, or deceive.
15 U.S.C. § 1051 (1976) (emphasis added). Thus, applicants attested only to their own subjective knowledge and belief.
To demonstrate that a federal registration was fraudulently procured, therefore, a challenging party must adduce evidence that the registrant actually knew or believed that someone else had a right to the mark.
See Metro Traffic Control, Inc. v. Shadow Network Inc.,
*197
The error, however, was harmless because
“
‘it is highly probable that [it] did not affect the outcome of the case.’ ”
West v. Philadelphia Elec. Co.,
D.
Marshak’s final argument concerning fraudulent procurement is that there was insufficient evidence to support the jury’s finding. The jury’s verdict must be sustained if it is rationally supported,
see Starceski v. Westinghouse Elec. Corp.,
In arguing that the evidence was insufficient, Marshak relies on the 1971 ruling of the New York state court denying Tread-well’s request for a preliminary injunction and opining that Treadwell had not established that Marshak or the members of his group “ha[d] been infringing upon [her] good name and good will.” App. 724. This was certainly evidence for the jury to consider, but it is insufficient to overturn the jury’s verdict. 9 We thus hold that fraud in the procurement of the federal mark was properly proven and that cancellation was justified.
IV.
We now consider Marshak’s arguments relating to Treadwell’s claim that
*198
Marshak was infringing upon her superior common-law right. As previously noted, the counterclaim of Treadwell’s Drifters asserted a claim under Section 48(a) of the Lanham Act, 15 U.S.C. § 1125(a), based on Marshak’s alleged infringement of their common law right to “The Drifters” mark. In order to prove this claim, the counter-claimant was required to show that “(1) the mark [was] valid and legally protecta-ble; (2) the mark [was] owned by the plaintiff; and (3) [Marshak’s] use of the mark to identify goods or services [was] likely to create confusion concerning the origin of the goods or services.”
Fisons Horticulture, Inc. v. Vigoro Indus., Inc.,
A.
Marshak contends that the District Court erred in entering judgment as a matter of law against him on the issue of abandonment. 10 We do not agree.
Section 45 of the Lanham Act, 15 U.S.C. § 1127, provides that “[a] mark shall be deemed abandoned ... [w]hen its use has been discontinued with intent not to resume use.” “To establish the defense of abandonment it is necessary to show not only acts indicating a practical abandonment, but an actual intent to abandon.”
Saxlehner v. Eisner & Mendelson Co.,
Thus, in order to show that there was an abandonment of the common law rights originally acquired by George Treadwell and The Drifters, Inc., Marshak bore the burden of “strictly” proving (a) that use of The Drifters mark had been discontinued in the United States 11 and (b) that the owner of the common law lights had the actual intent to abandon the mark. Marshak could have established a prima facie case of abandonment, however, by proving nonuse in this cоuntry for two *199 consecutive years. Lanham Act § 45, 15 U.S.C. 1127 (1994). 12
Here, the District Court found that there was no abandonment as a matter of law because “the .original Drifters recordings have been played on the radio and sold in record stores, without interruption, for the past 40 years.”
Marshak,
We find that defendants have failed to show either nonuse or intent to abandon. Even though plaintiffs disbanded their group in 1967 and ceased recording new material, there is no evidence suggesting that they failed to use the name Kings-men during the period from 1967 to the present to promote their previously recorded albums. Moreover, the fact that these individuals continue to receive royalties for Kingsmen recordings flies in the face of any suggestion of intent to abandon use of the name Kingsmеn. These plaintiffs have no more abandoned their right to protect the name of Kingsmen than have The Beatles, The Supremes or any other group that has disbanded and ceased performing and recording, but continues to collect royalties from the sale of previously recorded material. We must reject defendants’ contentions that the name Kingsmen has been abandoned to the public domain.
Id.
We concur with this reasoning, and we also agree with the District Court that it mandates the entry of judgment as a matter of law against Marshak. As the District Court put it, “[a] successful musical group does not abandon its mark unless there is proof that the owner ceased to commercially exploit the mark’s secondary meaning in the music industry.”
Marshak,
Marshak bore the burden of proving non-use and actual intent to abandon.
United States Jaycees v. Philadelphia Jaycees,
Marshak did not prove non-use, i.e., that the classic recordings of “The Drifters” were not played and that the resulting royalties were not paid. On the contrary, the parties stipulated that “The Drifters” records and albums continue to be played and sold in the United States and that many of their songs have now been recorded on compact disk and re-released. App. at 110. In addition, Treadwell testified that The Drifters, Inc. and Treadwell Drifters, Inc. have continuously received royalties from Atlantic Records for the sale of Drifters records in the United States. App. at 720. Likewise, Marshak failed to prove an actual intent to abandon. The continuous use of the mark in connection with the commercial exploitation of the group’s recordings in this country gave rise to a strong inference оf an intent not to abandon the mark.
In arguing that judgment as a matter of law was improper, Marshak relies on the following evidence. First, Treadwell dropped her 1971 action against Marshak in New York state court after the court denied her application for a preliminary injunction and issued an unfavorable opinion. Second, Treadwell did not oppose the federal registration of Marshak’s mark or *200 previously seek to have it canceled. Third, Treadwell failed to challenge numerous violations of “The Drifters” name, whereas Marshak stopped those uses through legal action. Fourth, Treadwell left for England in 1972. Fifth, Treadwell’s English recording contracts did not provide for distribution in the United States. However, once it is recognized that the commercial exploitation of classic Drifters recordings in this country constitutes use, it is apparent that the evidence that Marshak cites is insufficient to show either the non-use and or the actual intent to abandon that are necessary for a finding of abandonment.
B.
Marshak argues that the District Court erred in holding that he infringed the common-law rights held by Treadwell’s Drifters. We conclude, however, that Treadwell’s Drifters were entitled to judgment as a matter of law on their infringement claim.
As previously noted, Treadwell’s Drifters were required to show (1) that their mark was valid and legally protectable; (2) that they owned the mark; and (3) that Marshak’s use of the mark to identify his group was likely to create confusion concerning their origin.
Fisons Horticulture, Inc.,
With regard to the third element, Mars-hak argues that the District Court should not have disturbed the jury’s finding that Marshak had not used “The Drifters” name in such a way as to misrepresent the source of his goods or services or to falsely suggest a connection between those services and Treadwell’s Drifters. App. at 1562. We agree with the District Court, however, that a reasonable factfinder could not fail to find a likelihood of confusion on the facts of this case. As the District Court wrote, “Marshak’s group performs under the name ‘The Drifters’ and sings the same hit songs that were recorded and made famous by the original Drifters in the fifties and sixties. There is surely a likelihood of confusion because the public is misled to believe that Marshak’s singers and the famous Drifters records originate from the same source.” App. at 1681-82. Although infringement is generally a question for the jury, the evidence here mandated judgment for the eounterclaimant and justified the entry of the permanent injunction barring Marshak from using the Drifters mark. We have considered all of Marshak’s arguments, and we find no basis for reversal of the portions of the District Court’s orders that are properly before us.
V.
Fоr these reasons, we affirm the orders of the District Court insofar as they order cancellation of Marshak’s federal registration and permanently enjoin Marshak from using The Drifters name in commerce. We dismiss the appeal insofar as it contests the order for an accounting of profits.
Notes
. We are thus unable to express our view as • to whether any accounting should have been limited to the period of the appropriate statute of limitations. If on remand the District Court goes forward with the accounting, consideration of the propriety of that remedy will have to await the completion of the accounting and the entry of a final order. We recognize that this procedure may result in a considerable waste of time and resources in connection with the accounting, but the scope of our appellate jurisdiction leaves no alternative.
. We also note that the PTO has consistently held that the phrase "at any time” precludes a laches defense to a cancellation action premised on fraudulent procurement.
See Harjo v. Pro Football, Inc.,
. Section 37 provides:
In any action involving a registered mark the court may determine the right to registration, order the cancellation of registrations, and otherwise rectify the register with respect to the registrations of any party to the action. Decrees and orders shall be certified by the court to the Director, who shall make appropriate entry upon the records of the Patent and Trademark Office, and shall be controlled thereby.
15 U.S.C. §1119.
.The origins of the "at any time” language of Section 14(3) support this conclusion. This language derives from ‘Section 13 of the Trademark Act of 1905, 15 U.S.C. § 93. That section provided that "whenever any person shall deem himself injured by the registration of a trade-mark in the Patent Office he may
at any time
apply to the Commissioner of Patеnts to cancel the registration,” (emphasis added). The accepted meaning of the phrase "at any time" under the 1905 Act was that it excluded the defense of laches in a cancellation proceeding.
See Dwinell-Wright Co. v. National Fruit Prod. Co.,
. Marshak also relies (see Appellant's Br. at 33, Reply Br. at 2) on the statement in 5 J. Thomas McCarthy,
McCarthy on Trademarks and Unfair Competition
§ 31:59, at 31-108 (4th ed.2000), that "[w]hen fraud is used as a basis for challenging the validity of an incontestable registration, the claim must be asserted within the relevant statute of limitations.” On its face, this statement supports Marshak’s argument, but we decline to follow it in the particular context here, i.e., where Section 14(3) applies. The treatise does not attempt to explain how this sweeping statement can be reconciled with the language of Section 14(3), and elsewhere the treatise recognizes that a request to cancel based on fraud may be filed at any time. 5 McCarthy,
supra,
§' 31:80. Furthermore, the authority cited by the treatise in support of this statement,
Calzaturificio Rangoni S.p.A. v. United States Shoe Corp.,
. The section of Marshak’s brief concerning collateral estoppel (Appellant’s Br. at 48-49) does not refer to the dismissal of Treadwell’s 1971 action in New York state court. As noted, that case was dismissed because Tread-well did not comply with discovery. The District Court held that, under New York law, such a dismissal was without prejudice.
See Marshak,
. Much of the charge is set forth in the District Court's opinion.
See Marshak,
. In support of its instruction, the District Court relied on
G.H. Mumm & Cie v. Desnoes & Geddes, Ltd.,
. The evidence regarding the 1971 state court ruling does not undermine our conclusion that the error in the jury instruction discussed in part III.C,
supra,
was harmless. The jury instruction error related to the question of subjective knowledge or belief, but the evidence concerning the 1971 state court ruling is evidence of objective reasonableness, not the applicants’ subjective state of mind.
