Who Decides Priority: Hana Financial v. Hana Bank and the Jury's Role in Trademark Tacking

A unanimous Supreme Court held that whether a later mark may 'tack' onto an earlier mark's priority date is a question for the jury—locating the decisive moment in a clearance dispute in the fact-finder's assessment of consumer perception.

Trademark priority is usually framed as a contest of dates: whoever used a mark in commerce first owns it. But marks evolve. Logos are modernized, taglines are dropped, a word mark migrates into a new visual treatment. The doctrine of “tacking” asks when an owner who has altered its mark may nonetheless claim the priority date of the earlier version. In Hana Financial, Inc. v. Hana Bank, 574 U.S. 418 (2015) (No. 13-1211, argued December 3, 2014, decided January 21, 2015), a unanimous Supreme Court answered a narrow but consequential question about that doctrine: who decides whether tacking is warranted—judge or jury? Writing for the Court, Justice Sotomayor held that, when a jury trial has been requested and the facts do not compel summary judgment or judgment as a matter of law, the tacking question belongs to the jury. The holding is procedurally modest and substantively unanimous, yet it carries real weight for anyone who clears, polices, or litigates marks, because it confirms that the pivotal moment in many priority disputes is a fact-finder’s reading of ordinary consumer perception.

At a glance

  • Case: Hana Financial, Inc. v. Hana Bank, 574 U.S. 418 (2015); Sup. Ct. No. 13-1211.
  • Argued / Decided: December 3, 2014 / January 21, 2015 (unanimous), Justice Sotomayor writing.
  • Question presented: Whether the determination of trademark “tacking”—whether a later mark is the “legal equivalent” of an earlier one for priority purposes—is a question of fact for the jury or a question of law for the court.
  • Holding: Because tacking turns on how an ordinary consumer perceives the marks, it is a question for the jury when a jury has been empaneled and the record does not warrant judgment as a matter of law.
  • Status: Judgment of the U.S. Court of Appeals for the Ninth Circuit affirmed; jury verdict for Hana Bank stands.

The dispute and its dates

The case is a near-perfect specimen of a clearance failure that priority must untangle. The respondent, a Korean bank, was reorganized and renamed Hana Bank in 1991. In 1994 it established the “Hana Overseas Korean Club” to serve Korean expatriates in the United States, advertising those services in the U.S. in Korean-language print and including the name “Hana Bank” in some of that advertising. It opened a physical U.S. banking presence in 2002 under the “Hana Bank” name.

The petitioner, Hana Financial, was incorporated in California in 1994 and began using the “Hana Financial” mark—a pyramid logo paired with the words “Hana Financial”—in commerce in 1995, obtaining a federal registration in 1996. Hana Financial sued for infringement. Hana Bank’s defense was priority: it argued that its 1994 use of “Hana Overseas Korean Club” (and associated “Hana Bank” usage) predated Hana Financial’s 1995 first use, and that its current “Hana Bank” mark could tack onto that earlier use to claim the senior position. The case was tried to a jury, which—instructed on tacking in substantially the form Hana Financial proposed—returned a verdict for Hana Bank. The district court denied judgment as a matter of law, the Ninth Circuit affirmed, and the Supreme Court granted certiorari to resolve a circuit split over whether tacking is a question of law or fact.

Priority of use: the right that tacking protects

To understand why tacking matters, one has to start with priority. In the United States, trademark rights flow from use, not merely from registration. The senior user—the first to use a distinctive mark in commerce in connection with particular goods or services—generally prevails over later adopters in the relevant market. Priority is therefore the foundational entitlement in a clearance analysis: a search that surfaces an earlier user with superior rights is a search that has done its job, because it identifies the party who can exclude others.

Tacking exists because a rigid rule that any modification resets the priority clock would punish ordinary brand stewardship. As the Court explained, marks are living commercial signals; owners refine them constantly, and the law has long allowed an owner, “in limited circumstances,” to make modifications while retaining the priority of the original. The doctrine answers a practical anxiety in clearance work: if every visual refresh or wording tweak forfeited seniority, no owner could safely modernize a mark, and competitors could leapfrog an established brand merely because it had updated its logo. Tacking lets priority follow the commercial identity rather than the precise pixels.

The tacking doctrine: “the same, continuing commercial impression”

The substantive standard for tacking was not in dispute and the Court did not disturb it. Two marks may be tacked only when they are “legal equivalents”—that is, when they “create the same, continuing commercial impression” so that “consumers consider both as the same mark.” Critically, the Court stressed that this commercial impression “must be viewed through the eyes of a consumer.” The inquiry is not whether the marks are confusingly similar (the test for infringement) and not whether a trademark lawyer would regard them as substantially identical; it is whether ordinary purchasers perceive the old and new marks as the same source signal.

That framing did the analytical work. Because the controlling question is how an ordinary consumer perceives two marks, the Court reasoned, it is precisely the kind of factual judgment about a reasonable person’s understanding that juries have always made. Application of a legal standard to a particular factual record is the jury’s ordinary province, and careful instructions can ensure the standard is applied correctly. The Court therefore held that, where a jury has been requested and the evidence does not compel a contrary conclusion as a matter of law, tacking is for the jury.

Justice Sotomayor methodically dismantled Hana Financial’s four contrary arguments. First, Hana Financial contended that applying the “legal equivalents” standard is a legal exercise; the Court responded that mixed questions of law and fact applied to a specific record are routinely entrusted to juries. Second, it argued that tacking determinations create new law that will govern future disputes; the Court answered that a jury’s tacking verdict, like a jury’s verdict in tort, contract, or criminal cases, resolves the case before it without establishing a binding rule for others. Third, it warned that jury resolution would breed unpredictability; the Court noted that the uncertainty inherent in any fact-finding does not justify removing the question from the jury. Fourth, it pointed to past cases in which judges decided tacking; the Court explained that those arose in postures—bench trials, summary judgment, judgment as a matter of law—where judges properly decide, and they say nothing about the allocation of the question when a jury sits.

Open questions

The opinion is deliberately narrow, and several issues sit just outside its holding. Most prominently, the Court reaffirmed that judges may still resolve tacking on summary judgment, on judgment as a matter of law, or in a bench trial, but it offered little guidance on when the evidence is so one-sided that the question may be taken from the jury—leaving the practical line between a triable tacking dispute and one resolvable as a matter of law to be drawn case by case. The decision also leaves untouched the substance of the “legal equivalents” test: how much modification is too much, and what evidentiary showing (surveys, consumer testimony, expert analysis of commercial impression) suffices to establish that two marks read as one. Finally, although the Court analogized tacking to other consumer-perception questions in trademark law, it expressly declined to decide whether those neighboring inquiries—most notably likelihood of confusion, which several circuits already treat as factual—must be allocated to the jury on the same logic, even as its reasoning invites the comparison.

Implications

  • Priority can turn on a jury’s read of consumer perception. Where a party relies on tacking to establish seniority, the decisive question is likely to reach the fact-finder, which raises the stakes of trial presentation—survey evidence, consumer testimony, and the framing of “commercial impression” all become outcome-determinative.
  • Clearance must account for an opponent’s earlier, modified marks. A search that stops at the exact current mark is incomplete; a senior user may tack back to an earlier iteration, so clearance should map the evolution of a potential adversary’s branding, not just its present form.
  • Brand owners should document continuity when they modernize. Because tacking protects an owner who refines a mark, contemporaneous evidence that successive versions project the same commercial impression—consistent dominant elements, continuous use, marketing that bridges old and new—strengthens a later priority claim.
  • The procedural posture is a lever. Litigants who believe the tacking facts are one-sided should press for summary judgment or judgment as a matter of law; those who prefer a fact-finder’s latitude will keep the question in front of the jury.
  • The decision is narrow but stabilizing. By resolving the circuit split, Hana removes a threshold allocation dispute from tacking litigation, letting parties focus on the merits of commercial impression rather than fighting over who decides.

Frequently asked questions

What is trademark “tacking,” and why does it matter for priority? Tacking lets a trademark owner who has modified its mark claim the priority date of the earlier version, provided the two are “legal equivalents” that create the same, continuing commercial impression. It matters because priority—who used a distinctive mark first—generally determines who owns the mark and can exclude others; without tacking, every modernization of a logo or wording would risk forfeiting seniority.

Does Hana change the standard for when tacking is allowed? No. The Court left the substantive test intact: two marks may be tacked only if ordinary consumers perceive them as the same mark. Hana decided only who answers that question—the jury, in a jury trial where the evidence does not compel judgment as a matter of law—not what the answer should be.

Can a judge ever decide tacking after Hana? Yes. The Court expressly preserved a judge’s authority to resolve tacking on summary judgment, on judgment as a matter of law, or in a bench trial. The jury-question holding applies when a jury has been empaneled and the record presents a genuine factual dispute about consumer perception.
