B&B Hardware, Inc. v. Hargis Industries, Inc.
The Supreme Court ruled that when a federal trademark board decides that two brand names are too similar, that decision can bind a later infringement lawsuit over the same marks, as long as the usual rules for treating an issue as already settled are met.
The decision means companies can no longer assume that losing a trademark-registration fight before the agency leaves them free to relitigate the same confusion question from scratch in federal court, which could make registration disputes carry higher stakes.

How it got here: A federal jury found no infringement; B&B appealed, and the Eighth Circuit affirmed rejecting issue preclusion, prompting the Supreme Court to grant review.
The Case in Depth
What happened
B&B Hardware and Hargis Industries both make metal fasteners and both wanted their products linked with tight seals: B&B owns the trademark SEALTIGHT for aerospace fasteners, and Hargis sought to register SEALTITE for construction fasteners. B&B opposed Hargis's registration before the trademark board, arguing the names were too similar, while separately suing Hargis for trademark infringement in federal court over the same two marks.
The question before the Court
If a trademark board already ruled two brand names too similar to register, must a later court trial on infringement accept that finding instead of deciding confusion all over again?
The Court's answer
Yes — a trademark board's ruling on likelihood of confusion can bind a later infringement lawsuit over the same marks, as long as the ordinary requirements for treating an issue as already settled are satisfied. The key requirement is that the product uses the board actually considered must be materially the same as the uses at issue in the infringement case; if so, the parties cannot relitigate the confusion question again in court.
The Court rejected arguments that registration and infringement always involve different legal standards, different procedures, or lower stakes that make preclusion categorically unavailable. It held those are reasons preclusion might not apply in some cases, not reasons it can never apply, and sent the case back for the lower courts to decide whether preclusion fits these particular facts.

Why it matters
Businesses fighting over confusingly similar brand names now have more reason to litigate registration disputes aggressively, since losing before the trademark board can foreclose re-arguing the same confusion issue in a later infringement suit, saving courts time but raising the stakes of early administrative proceedings.
What changes now
The case returns to the Eighth Circuit, and eventually the district court, to apply the Supreme Court's rule and determine whether the specific product uses the trademark board considered were materially the same as those at issue in the infringement trial. If so, Hargis may be barred from re-arguing that there was no likelihood of confusion. This is a final merits ruling, not a temporary order, though the ultimate outcome on remand remains open.
What this does not decide
The Court did not decide that every trademark board registration decision will block relitigation in later infringement suits — it emphasized that many registration decisions will not meet the ordinary requirements for preclusion, especially when the board did not consider the same real-world product uses at issue in the infringement case.
Concurrences and dissents
Concurrence — Justice Ginsburg
Justice Ginsburg joined the majority in full but wrote separately to underscore that preclusion will often not apply in practice, because many registration disputes are decided by comparing marks in the abstract rather than by looking at how they are actually used in the marketplace. When that is how a case was decided, she stressed, there will be no preclusive effect on the confusion issue in a later infringement suit.
Dissent — Justice Thomas
“The common law does not support a general presumption in favor of administrative preclusion for statutes passed before this Court's decision in Astoria”Thomas's core objection that the majority's preclusion presumption lacks historical support for older statutes like the Lanham Act.
Justice Thomas argued the presumption favoring administrative preclusion was announced only in weak dictum in a 1991 case and should not extend to a 1946 statute like the Lanham Act. He found nothing in the text, structure, or history of the Act suggesting Congress wanted trademark board decisions to bind later infringement suits, noting the Act gives the board only limited authority and provides for full new-trial review in court. He also warned that treating the board's fact-finding as binding on a private property right raises serious constitutional concerns under Article III, though he rested his dissent on statutory grounds alone.
How the Court got there
The legal reasoning, step by step
- The Court applied issue preclusion — the rule that once an issue has been fully and fairly decided, the same parties cannot relitigate it in a later case — and asked whether that rule can ever apply to a decision made by an agency rather than a court.
- Relying on precedent, the Court held that when Congress lets an agency resolve disputes in a court-like way, courts should presume Congress wanted the agency's decisions to carry the same preclusive weight as a court judgment, unless the statute clearly says otherwise.
- The Court then asked whether the trademark statute itself rules out that presumption, and found nothing in the text or structure of the law suggesting Congress meant to block preclusion, distinguishing this case from an earlier ruling where treating the agency proceeding as binding would have made a required follow-up lawsuit pointless.
- The Court rejected the idea that registration and infringement use different legal tests for confusion, explaining that both proceedings ask essentially the same question under nearly identical statutory language, so differences in the specific factors each tribunal considers do not by themselves defeat preclusion.
- The Court concluded that procedural differences between the agency and a courtroom trial, and the fact that registration stakes can be lower than infringement stakes, do not categorically bar preclusion either — they simply mean preclusion will not fit every case.
- The Court therefore adopted a case-by-case rule: preclusion applies whenever the specific product uses the agency actually decided are materially the same as the uses at issue in the later infringement case, along with the other ordinary requirements for preclusion.

The Court said this case differs because registration is a separate proceeding, not a required first step before suing in court.
