The Supreme Court Decides Trademark Tacking Case

Last week the Supreme Court decided its first substantial trademark case in over ten years. Hana Financial, Inc. v. Hana Bank is a trademark infringement action involving the “tacking” of trademarks. Tacking is “a rule that allows the owner of the mark to make slight changes in the mark, without losing the priority that the trademark owner has based on the date when it first started using the original mark.”[1] The emphasis is on what the court calls a “continuing commercial impression.” Generally, tacking involves three trademarks, the original “senior” trademark, a second “junior” trademark unrelated to the first mark, and a third, modified version of the senior trademark.[2]  When tacking is applied, the modified senior user’s mark is allowed to claim the priority date of its original mark, even though the mark has been changed in some way.  But tacking can only be applied when there is a “legal equivalent”, meaning the two marks create the same, continuing commercial impression to consumers.

In this case, the mark “Hana” was first used by Hana Financial in 1995. Hana Bank did not use the Hana Bank mark until 2002, but argued that it could “tack” the Hana Bank mark to its 1994 mark “Hana Overseas Korean Club” and “Hana Bank” in Korean. A jury decided that Hana Bank could tack the mark to its original use of the mark in 1994. Hana Financial appealed, arguing that tacking is a question of law for a judge to decide, but the Ninth Circuit held that “whether two marks may be tacked for purposes of determining priority is a question for the jury.”[3]

The question presented to the Supreme Court is whether tacking is a question of law to be decided by a judge, or whether it is a question of fact to be determined by a jury. The Supreme Court unanimously decided that a jury can apply the tacking doctrine, reaffirming the lower court’s decision that the jury is best equipped to decide issues of an ordinary consumer’s impression.

This decision reiterates the importance of the jury. Justice Sotomayor explained “we have long recognized across a variety of doctrinal contexts that, when the relevant question is how an ordinary person or community would make an assessment, the jury is generally the decisionmaker that ought to provide the fact-intensive answer.”[4]
