In a trademark dispute between SunAmerica Corporation and Sun Life Assurance Company of Canada, the Eleventh Circuit reviewed a case concerning the use of the mark "SUN LIFE." SunAmerica, comprising a Delaware corporation and its subsidiary, challenged Sun Life of Canada, a Canadian corporation and its U.S. subsidiary. The district court had initially ruled in favor of Sun Life of Canada, permanently enjoining SunAmerica from using the "SUN LIFE" mark due to "inevitable confusion" in the marketplace. Although Sun Life of Canada was the senior user of the mark, its past acquiescence to SunAmerica's use raised the issue of estoppel.

However, the court noted that the existence of inevitable confusion permitted revival of the senior user's claim despite estoppel. It emphasized the need for the district court to explore alternative remedies rather than imposing a complete injunction on SunAmerica. The case was remanded for further proceedings due to ambiguity in the district court’s order regarding the consideration of alternative relief.

The background details reveal that SunAmerica had initially filed claims against Sun Life of Canada for unfair competition and trademark infringement in 1989, alleging that Sun Life of Canada's use of similar marks was causing confusion. A counterclaim from Sun Life sought to prohibit SunAmerica's use of the "SUN LIFE" mark. The district court found the marks confusingly similar and initially issued a permanent injunction against Sun Life of Canada regarding its use of "SUN LIFE (U.S.)."

Upon appeal, the Eleventh Circuit vacated the injunction due to the oversight of Sun Life's counterclaim and remanded the case for further examination. The opinion of Judge Birch, which elaborated on the case's procedural history and legal framework, was adopted by the court and attached as an appendix, aiding in the remand process.

The district court, on remand after SunAmerica I, determined that Sun Life of Canada held enforceable rights in its SUN LIFE trademarks and that a likelihood of confusion existed between SUN LIFE OF AMERICA and SUN LIFE OF CANADA. Despite finding such confusion, the court also noted that Sun Life of Canada had acquiesced to SunAmerica's use of the contested marks, which generally bars a senior user's trademark claim unless inevitable confusion is present. The court concluded that inevitable confusion did exist, thereby reinstating Sun Life of Canada's trademark rights and permanently enjoining SunAmerica from using the SUN LIFE mark. 

SunAmerica subsequently sought to alter the judgment, stay the injunction pending appeal, and requested a new trial, all of which were denied by the district court. SunAmerica then filed an Emergency Motion to Stay the injunction and expedite the appeal, which was partially granted, as the stay was denied but the appeal was expedited. In compliance with the injunction, SunAmerica changed its name to "SunAmerica Life Insurance Company" during the appeal process.

In arguing for a stay, SunAmerica claimed that the name change would be commercially and legally irreversible, effectively negating any chance of relief if they won the appeal. Despite these assertions, the district court and later this Court rejected the argument that compliance would moot the appeal, leading to SunAmerica’s compliance with the injunction. Ironically, after changing its name, SunAmerica contended that the appeal was not moot, contradicting its earlier claims regarding the implications of the name change.

SunAmerica previously represented to the district and appellate courts that a name change would be irreversible and would moot its appeal. However, it later asserted that the effects of the name change could be reversed, suggesting that relief from the injunction would allow beneficial use of the SUN LIFE mark through a subsidiary. This inconsistency led to questioning by the court regarding which statements were false. SunAmerica's counsel argued that the name change did not moot the appeal, emphasizing that even if reverting was impractical, other uses of the mark were possible. The court noted that SunAmerica's earlier claims were supported by affidavits asserting the name change would moot the case, thus necessitating a satisfactory explanation for the contradictory assertions. The court cautioned that such tactics could lead to estoppel, preventing SunAmerica from denying its previous claims about the name change's irreversibility. Ultimately, the court decided against applying estoppel, citing two reasons: the lack of prior notice to parties regarding such a doctrine in mootness cases and the district court’s explicit finding that a name change would not be irreversible, indicating that the lower court was not misled.

The analysis of estoppel may yield different results in future cases without explicit factfinding. SunAmerica contended that if the case were deemed moot, the court would be obligated to vacate the district court’s judgment and injunction based on the precedent set by United States v. Munsingwear, Inc., which outlines the practice of vacating judgments in moot cases. However, the court chose not to dismiss SunAmerica's appeal as moot, making a definitive resolution on this point unnecessary. It acknowledged that vacatur is an equitable remedy and that applying mootness by estoppel would require equitable considerations when deciding whether to vacate the district court's judgment to achieve a just outcome. The court expressed concern that granting vacatur could improperly reward a party for inconsistent representations.

In assessing traditional mootness, the court determined that the case did not become moot after SunAmerica complied with the district court's injunction by renaming itself. The appellate court could provide meaningful relief if SunAmerica prevailed, allowing for potential commercial use of the SUN LIFE mark despite claims of "commercial impossibility" in reversing the name change. The court affirmed that a case does not become moot merely because complete restoration of the status quo is impossible, as partial remedies can suffice to prevent mootness. Consequently, the court concluded that it retains jurisdiction to address the merits of SunAmerica's appeal.

Regarding the appropriateness of the injunctive relief granted by the district court, the appeal's resolution will consider the district court's findings of fact, application of law, and the injunctive relief itself, with factfinding reviewed under a clearly erroneous standard and legal applications under a de novo standard.

The district court's grant of injunctive relief is reviewed for abuse of discretion, affirming unless there is a "clear error of judgment" or incorrect legal standard applied. Key findings from the district court include that Sun Life of Canada is the senior user of the SUN LIFE mark, that there is a "powerful" and "substantial" likelihood of confusion between the marks used by Sun Life of Canada and SunAmerica, and that current confusion is not due to Sun Life of Canada's actions. Additionally, geographic modifiers or distribution channel separations do not alleviate the confusion. SunAmerica, on appeal, does not contest the district court's factfindings but argues that the court failed to consider whether Sun Life of Canada’s post-acquiescence actions contributed to confusion; however, this premise contradicts the court's findings. As such, SunAmerica's challenges to the factfindings are either waived or lack merit. 

In trademark infringement, a claimant must show enforceable rights in their mark and that the alleged infringer's mark is confusingly similar. Sun Life of Canada satisfied these elements, which SunAmerica does not dispute. The district court then examined SunAmerica's affirmative defenses, specifically focusing on the defense of acquiescence, which requires proof that the senior user actively consented to the infringer's use, that there was an unexcusable delay in asserting rights, and that this delay caused undue prejudice to the infringer.

The district court found that Sun Life of Canada acquiesced to SunAmerica's use of certain marks, a conclusion that Sun Life does not dispute. Acquiescence typically prevents a senior user from asserting trademark rights against a junior user if consent to use was given. This creates a mutual legal duty to respect each other's marks, establishing parity between them. However, acquiescence is not absolute; if "inevitable confusion" arises from the use of the marks, a senior user's claim may be revived from estoppel. This concept of "inevitable confusion" is more stringent than a mere likelihood of confusion and is assessed on a case-by-case basis. The district court determined that inevitable confusion existed and deemed it necessary to revive Sun Life's trademark rights, a finding that SunAmerica does not contest. SunAmerica presents two arguments against this ruling: first, that inevitable confusion applies only to trademark registration and not infringement cases, which contradicts established precedent; and second, that the district court erred in automatically reviving Sun Life’s claim without a balancing test, misinterpreting the discretion implied by the term "may" in the relevant case law.

District judges are not required to apply a complex balancing test to determine if a senior user's claim can be revived from estoppel upon a showing of inevitable confusion. If a senior user demonstrates inevitable confusion, their previously estopped claims can be heard, as they are no longer barred by acquiescence. SunAmerica's proposed balancing test complicates the already intricate analysis without necessity. Once inevitable confusion is established, the district court must then determine the appropriate scope and nature of equitable relief based on traditional principles outlined in Section 34(a) of the Lanham Act, which allows for flexibility and practicality in addressing the unique circumstances of each case. This involves evaluating the harm suffered by the senior user, potential remedies, defenses, and the impact on competition. Courts are required to tailor injunctions closely to the specific harm identified.

Equitable relief in trademark cases should be limited to what is necessary to differentiate between products, particularly in cases of acquiescence where competing marks are of equal dignity. In such instances, a total injunction against a junior user's use of a mark may cause undue hardship, especially if the junior user can demonstrate feasible alternatives to address the senior user's claims and the public interest in reducing confusion. Courts must consider the history of the case, particularly whether the senior user has acted with "unclean hands" by creating confusion to revive its claims after previously allowing the junior user to establish goodwill. The law prioritizes the public interest in preventing confusion while minimizing hardship on both parties. Therefore, when fashioning a remedy, courts should explore less severe options than a total injunction, balancing the legitimate interests of both parties while ensuring that the public interest remains paramount.

A total injunction may be warranted against a junior user when confusion in the marketplace arises due to their use of a mark already held by a senior user. Typically, the injunction is directed at the junior user, as they are responsible for the confusion despite any previous acquiescence by the senior user. Courts should consider that the senior user should not bear a greater remedial burden than the junior user. While these presumptions are generally applicable, they are not absolute, and courts must exercise equitable discretion in their judgments.

Reviewing a district court's remedy decision involves examining factual findings for clear error and legal principles for correctness. The court's ultimate remedial decision is evaluated for abuse of discretion, allowing for a range of acceptable outcomes. In this specific case, the district court found that Sun Life of Canada had proven the necessary confusion to revive its claim and subsequently issued an injunction against SunAmerica's use of the SUN LIFE mark.

The district court issued a complete injunction against SunAmerica's use of the SUN LIFE mark, despite SunAmerica proposing five alternatives to mitigate confusion: 1) using geographic modifiers for both parties' marks, 2) subdividing the market to allow SunAmerica to use the mark in the independent broker-dealer market while restricting Sun Life of Canada to its career agent sales force, 3) prohibiting Sun Life of Canada from using the SUN LIFE (U.S.) mark, 4) conducting mutual educational campaigns to differentiate the brands, and 5) establishing guidelines for the use of geographic modifiers and logos. The district court rejected the first three alternatives, finding that geographic modifiers would not reduce confusion, that market subdivision was unfeasible, and that prohibiting the SUN LIFE (U.S.) mark was unnecessary since it hadn’t been used since May 1992. These factfindings were not deemed clearly erroneous. However, it is unclear if the court evaluated the last two proposed remedies before imposing the complete injunction. The appellate court remanded the case for the district court to reassess whether any of SunAmerica's alternatives could effectively minimize marketplace confusion. The district court retains discretion over whether further hearings are needed. If the district court finds that none of the alternatives would suffice to reduce confusion, the complete injunction will remain. Conversely, if it identifies feasible remedies, it should select among them. The appellate court has left the permanent injunction in place for reevaluation based on the outcomes of the new proceedings.

The panel will maintain jurisdiction over any future appeals due to the complexity of the case involving trademark disputes between SunAmerica Corporation and Sun Life Assurance Company of Canada. SunAmerica claims that Sun Life of Canada’s use of the mark SUN LIFE (U.S.) is confusingly similar to its own mark SUN LIFE OF AMERICA, leading to legal action. The district court, while denying summary judgment for most claims due to unresolved factual disputes, did issue a permanent injunction against Sun Life of Canada regarding the SUN LIFE (U.S.) mark, determining it was confusingly similar to SunAmerica's mark. However, the appellate court found this injunction improper, noting that the district court did not adequately address Sun Life of Canada’s counterclaim, which argues that SunAmerica is the junior user of the "Sun Life" mark and lacks enforceable rights. The appellate court ruled that this counterclaim must be resolved before determining whether SunAmerica is entitled to an injunction. Consequently, the permanent injunction is vacated, and the case is remanded to the district court for further proceedings.

Circuit Judge Birch expresses concerns regarding the district court’s analysis and suggests that a mere remand without commentary could lead to issues in the future. He provides observations intended to assist the parties and the court in resolving the case. 

The district court established that Sun Life of Canada and SunAmerica have been providing similar insurance products and targeting similar markets through comparable advertising methods. Historically, Sun Life of Canada, established in 1865 and the first to use the "Sun Life" mark in the U.S., has offered a wide range of insurance products aimed at investment-oriented clients. In contrast, Sun Life of America, founded in 1890 and operating under its current name since 1916, has focused primarily on basic life insurance for industrial workers and has remained smaller and more specialized.

For much of their existence, both companies coexisted without conflict due to their distinct product offerings and market strategies. They maintained a cordial relationship, with Sun Life of Canada granting consent for Sun Life of America to expand into overlapping states. Tensions began to arise in the early 1970s when Sun Life of Canada created its U.S. subsidiary and sought new distribution avenues, including partnerships with brokerage firms. Concurrently, Sun Life of America underwent modernization and diversification after being acquired by Kaufman & Broad, which led to its experimentation with annuities and investment markets.

Tensions began between Sun Life of Canada and Sun Life of America in the early 1980s due to the similarity of their names and the overlap in their business operations. Sun Life of America first protested the use of the mark SUN LIFE (U.S.) by Sun Life of Canada in June 1983, but Sun Life of Canada continued its use. By 1988, Sun Life of Canada had sold approximately $4 billion in annuity products under this mark. Previous attempts to mitigate the conflict, including agreements in 1980 and a non-formal understanding in 1982 regarding geographic modifiers, failed to resolve the issue.

As Sun Life of America evolved to market annuities to investment-oriented clients, it abandoned its original focus on life insurance for industrial workers. In June 1989, the dispute escalated into litigation, with Sun Life of America asserting multiple claims, primarily focusing on trademark infringement regarding the use of SUN LIFE (U.S.). SunAmerica alleged that this usage misled the public into believing that Sun Life of Canada's products originated from SunAmerica, violating the Lanham Act.

Sun Life of Canada counterclaimed, asserting it had used the name SUN LIFE OF CANADA long before Sun Life of America adopted its name, and that Sun Life of America's actions created confusion in the marketplace. Sun Life of Canada sought to enjoin Sun Life of America from using its name and related marks.

Both parties submitted cross motions for summary judgment regarding SunAmerica's challenge to the use of the name SUN LIFE (U.S.), while no motion was filed concerning Sun Life of Canada's counterclaim. The district court granted summary judgment to SunAmerica, determining a likelihood of confusion based on an analysis of the marks using the established seven-factor test. The court found that SUN LIFE (U.S.) could be seen as synonymous with SUN LIFE OF AMERICA, due to the companies' similar products, distribution channels, clients, advertising, and evidence of actual confusion. Consequently, Sun Life of Canada was permanently enjoined from using SUN LIFE (U.S.) in any promotional materials. 

Sun Life of Canada argued that the district court incorrectly granted the injunction without fully resolving its counterclaim, which asserted that SunAmerica had no enforceable rights to the "Sun Life" mark. The counterclaim posited that confusion arises from both parties having similar names and that Sun Life of Canada had used its name long before SunAmerica’s first use. If Sun Life of Canada succeeds in its counterclaim, the basis for the injunction against it would be invalidated. The appellate view supports that a thorough determination of the counterclaim issues was necessary before issuing a permanent injunction in favor of SunAmerica, which is founded on section 43(a) of the Lanham Act regarding the likelihood of confusion in commerce.

To obtain injunctive relief under section 43(a) of the Lanham Act, a plaintiff must demonstrate: 1) ownership of trademark rights in the relevant mark or name, and 2) that the defendant has used a mark that is identical or confusingly similar, creating a likelihood of confusion. Sun Life of Canada's counterclaim challenges SunAmerica’s claim of enforceable trademark rights in "SUN LIFE OF AMERICA." The district court's issuance of a permanent injunction was deemed premature as it did not explicitly rule on SunAmerica's rights to use the "Sun Life" mark, nor did it address the counterclaim's implications. Sun Life of America needed to prove the absence of any genuine material fact regarding its trademark rights to secure summary judgment. The district court failed to make specific findings of fact or conclusions of law related to this matter, which is essential for meaningful appellate review. Although SunAmerica contends that the court addressed the counterclaim, the commentary provided was insufficient to constitute a definitive ruling. Consequently, the lack of clarity regarding the district court's factual and legal reasoning complicates any potential appellate review, indicating the need for a more thorough examination upon remand.

The district court suggested that SunAmerica holds enforceable rights in the SUN LIFE OF AMERICA mark, indicating that Sun Life of Canada is barred from contesting this usage due to its long-standing allowance of another party's use of the mark. The court referenced several legal doctrines, such as acquiescence, equitable estoppel, laches, and waiver, without providing detailed explanations or relying on relevant trademark case law. A more detailed legal analysis is deemed necessary, particularly focusing on Sun Life of Canada's ability to present a prima facie case under section 43(a) of the Lanham Act.

Sun Life of Canada, which registered SUN LIFE OF CANADA in 1967 and several other "Sun" marks thereafter, must demonstrate its first use of the unregistered mark and establish a protectable interest in it, either through inherent distinctiveness or acquired secondary meaning. The likelihood of confusion, a critical factor, should be evaluated using the seven-factor test from relevant case law. The district court must first ascertain the extent of Sun Life of Canada's protectable interest and any potential confusion before addressing SunAmerica's affirmative defenses.

SunAmerica's likely defense appears to be based on acquiescence, which requires proof of active or explicit consent from Sun Life of Canada for SunAmerica's use of the mark. SunAmerica claims that Sun Life of Canada provided express permission to use SUN LIFE OF AMERICA, including assistance with regulatory compliance, suggesting that this defense hinges on demonstrating such consent.

Sun Life of Canada actively represented that it would not assert a right or claim against Sun Life of America, and the delay in making such an assertion was deemed inexcusable, resulting in undue prejudice to Sun Life of America. Acquiescence would prevent Sun Life of Canada from extinguishing Sun Life of America's use of the "SUN LIFE OF AMERICA" mark unless there is inevitable confusion between the two marks. The concepts of "estoppel" and "estoppel by laches" are acknowledged, with a distinction made regarding the district court's use of "equitable estoppel" language from workers' compensation law, which is not rooted in trademark law.

Sun Life of Canada argues that even if Sun Life of America could prove elements of acquiescence, it could still revoke its acquiescence because it represents an implied license. However, the court clarifies that once all elements of acquiescence are established, permission to use the mark becomes irrevocable. The court notes that the analysis of the first and third elements of acquiescence is straightforward, but the second element—whether the delay was excusable—requires further examination. The court indicates that the district court should consider not just the duration of the delay but also the reasons behind it. Sun Life of Canada asserts that until 1989, it had no reason to challenge Sun Life of America's use of the mark due to differences in products and markets, suggesting that an infringement challenge would have been futile.

Sun Life of Canada contends that because Sun Life of America is the junior user of the "Sun Life" mark, it has a duty to avoid confusion with the first user's mark, a legal position that is recognized but limited. Sun Life of Canada argues that this duty exists even if the first user abbreviates its mark, implying that Sun Life of America has acted at its peril since adopting the "Sun Life" mark in 1916.

One who adopts a mark similar to another's for closely related goods must operate with caution, particularly if they were aware of the senior user's mark prior to use. This principle emphasizes the responsibility of the second user to prevent confusion, which includes anticipating potential abbreviations of the senior user's mark. For instance, the Seventh Circuit in Forum Corp. held that the junior user must choose a mark that avoids confusion with the senior user's salient portions, even if the senior user has abbreviated its mark. If the senior user has permitted the junior user's use of a mark containing significant elements of the senior user's mark, the senior user may be estopped from later claiming confusion due to that mark.

In cases where the senior user has actively acquiesced to the junior user's mark, the mutual duty to avoid confusion arises. The senior user cannot later adopt a name that increases confusion after having allowed the junior user to use a similar mark. For example, if the senior user consents to a junior user's use of a mark, it cannot subsequently change its own mark or claim confusion. In this context, whether Sun Life of Canada has acquiesced to Sun Life of America’s use of "Sun Life" is critical; if no such acquiescence exists, Sun Life of America must take steps to avoid confusion with Sun Life of Canada's mark.

The likelihood of confusion determination relies on a seven-factor test assessing elements such as product similarity, channels of commerce, and advertising media. Sun Life of Canada has a duty to respect the trademark SUN LIFE OF AMERICA if it has acquiesced to its use. The original court's decision regarding the permanent injunction has been vacated, and the issue of whether SUN LIFE (U.S. is confusingly similar to SUN LIFE OF AMERICA will be left for the district court to analyze with discretion. For SunAmerica to establish a prima facie case under section 43(a) of the Lanham Act, it must demonstrate a protectible trademark interest in SUN LIFE OF AMERICA and that Sun Life of Canada’s use of SUN LIFE (U.S. creates a likelihood of confusion. This requires SunAmerica to prove either inherent distinctiveness or acquired secondary meaning for its mark. The district court must employ the seven-factor test to evaluate the likelihood of confusion. Sun Life of Canada argues that confusion may stem from SunAmerica's own use of a similar mark and its recent entry into the annuity market, but historical similarities alone do not negate SunAmerica's potential for an injunction. If the district court finds that SunAmerica holds protectible trademark rights, it must ensure that no actions increase confusion beyond the level present at the time of acquiescence, regardless of SunAmerica's market expansions or historical usage of "Sun Life."

The district court's potential injunction against Sun Life of Canada's use of "SUN LIFE (U.S.)" hinges on establishing a likelihood of confusion based on evidence. Following the resolution of Sun Life of Canada's counterclaim, the court must evaluate SunAmerica's prima facie case under Section 43(a) and consider Sun Life of Canada's defenses of laches and acquiescence. Sun Life of Canada argues that SunAmerica, aware of the mark's use since 1982, delayed filing suit until 1989, which constitutes laches due to an inexcusable delay leading to undue prejudice. To support this, Sun Life of Canada must demonstrate three elements: delay, lack of excusable reason, and demonstrated prejudice.

Additionally, Sun Life of Canada contends that SunAmerica should be estopped from contesting the mark due to implied acquiescence, arguing that SunAmerica acted as an agent and endorsed the use of "SUN LIFE (U.S.)" by selling related products. This defense also requires proof of active representation, inexcusable delay, and undue prejudice. The court is advised to thoroughly evaluate SunAmerica's reasons for any perceived acquiescence and delay.

The case involves a complex history of over a century, with interrelated claims and defenses from both parties. A comprehensive, detailed analysis of trademarks, products, and market dynamics is necessary to reach a resolution that can withstand appellate scrutiny, as the situation involves significant competition and potential confusion.
