Supreme Court Holds That TTAB Decisions On Likelihood Of Confusion May Bind Courts In Infringement Litigation

In a 7 - 2 decision issued March 24, 2015, the U.S. Supreme Court held that decisions of the Trademark Trial and Appeal Board (TTAB) on the issue of likelihood of confusion, made in registration cases, can be binding on courts in deciding the same issue in subsequent infringement cases. Such "issue preclusion" will likely arise if the uses of the marks before the court are materially the same as the uses considered by the TTAB. The decision in B&B Hardware, Inc. v. Hargis Industries, Inc. is likely trigger more hotly contested — and more expensive — TTAB litigation.

In this case, B&B owned a registration for "Sealtight" for metal fasteners used in the aerospace industry. Hargis sought to register "Sealtite" for metal screws used in the manufacture of buildings. B&B opposed registration, claiming that use of the marks on the respective goods would create a likelihood of confusion. The TTAB agreed and sustained the opposition. In a parallel infringement action, the district court refused to be bound by the TTAB decision, reasoning that the TTAB is not an Article III court. The jury went on to find that confusion was not likely.

The Eighth Circuit affirmed. It held that while an administrative agency's decision can be a basis for applying collateral estoppel, the doctrine was not appropriate in this context, primarily because the TTAB and the Eighth Circuit use different factors to evaluate likelihood of confusion.

In an opinion by Judge Alito, the U.S. Supreme Court reversed. It held first that "issue preclusion is not limited to those situations in which the same issue is between two courts" (emphasis in original). Rather, under Astoria Fed. Sav. & Loan Assn. v. Solomino, 501 U.S. 104 (1991), "courts may take it as a given" that Congress intends issue preclusion to apply to administrative proceedings where appropriate, except when a statutory purpose to the contrary is evident. The court held that no such purpose was evident in the Lanham Act of 1946.

The court acknowledged that the TTAB considers different factors than do courts in determining likelihood of confusion. In particular, the TTAB compares marks and goods as they are set forth in prior registrations and pending applications, whereas a court will consider all elements of the parties' uses, including the context in which the marks appear on packaging. But the court held that the same legal standard of "likelihood of confusion" always applies, even if different usages are...
