Lucky Brand Dungarees, Inc. v. Marcel Fashions Group, Inc.
The Supreme Court unanimously ruled that Lucky Brand could invoke its settlement agreement defense in a 2011 trademark lawsuit, even though it had not pursued that defense in a 2005 suit between the same parties.
Because the two lawsuits involved different conduct, different marks, and different time periods, they were not the 'same' lawsuit for preclusion purposes — so Lucky Brand was free to raise defenses it had not used before.
How it got here: On remand from a prior Second Circuit ruling, Lucky Brand raised a settlement release defense; the District Court accepted it, but the Second Circuit applied "defense preclusion" to block it; Lucky Brand asked the Supreme Court to step in.
The Case in Depth
What happened
Two apparel companies — Lucky Brand and Marcel Fashions — both use the word "Lucky" on clothing, leading to nearly two decades of lawsuits. After a 2003 settlement in which Marcel agreed to release claims about Lucky Brand's own marks, Marcel sued again in 2011, this time alleging infringement based on Lucky Brand's standalone "Lucky"-branded marks. When Lucky Brand invoked the settlement release as a defense, Marcel argued Lucky Brand had forfeited that defense by not pressing it in the parties' earlier 2005 litigation.
The question before the Court
Can a company be blocked from using a settlement agreement as a defense in a new lawsuit, simply because it failed to press that defense fully in an earlier lawsuit between the same parties?
The Court's answer
No — Lucky Brand was not blocked from raising its settlement agreement defense. The rule that bars a party from raising arguments it could have made in an earlier lawsuit (called claim preclusion) only applies when the two lawsuits involve the same underlying claims — specifically, a shared "common nucleus of operative facts." The Court found that standard was not met here.
The 2005 lawsuit centered on Lucky Brand's use of the phrase "Get Lucky," while the 2011 lawsuit was about Lucky Brand's use of its own separate "Lucky"-branded marks during a later period. Different marks, different conduct, different time — so the two suits were not the same claim. Without that identity, there was no legal basis to strip Lucky Brand of its settlement defense in the newer case.

Why it matters
Companies locked in repeat litigation against the same opponent can still deploy valid contractual defenses — like a prior settlement release — in new suits, as long as the new suit involves different conduct or claims. Defendants in trademark and other ongoing disputes won't automatically forfeit unused defenses just because earlier litigation between the same parties occurred.
What changes now
The Second Circuit's ruling blocking Lucky Brand's settlement defense is undone, and the case goes back to lower courts to be decided with the release defense on the table. If the settlement agreement's release provision does bar Marcel's 2011 claims — as the District Court originally held — Lucky Brand may win outright. The Supreme Court's decision resolves a split among federal appeals courts over when, if ever, defendants can be barred from using defenses they skipped in earlier suits.
What this does not decide
The Court explicitly declined to decide whether claim preclusion can ever bar a defense when two lawsuits do share the same underlying claims. That question — whether "defense preclusion" is ever valid — remains open. This ruling only addresses situations where the two suits involve different conduct, different claims, and different time periods.
How the Court got there
The legal reasoning, step by step
- The case turns on whether 'defense preclusion' — a rule the Second Circuit created to bar defendants from raising defenses they skipped in earlier litigation — is a valid legal doctrine. The Court framed the question by looking to the two established forms of preclusion: issue preclusion (which bars re-litigating issues actually decided before) and claim preclusion (which bars raising issues that could have been raised in an earlier suit involving the same claim). Any bar on defenses must fit within one of these two existing doctrines.
- Because no one argued that the release defense was actually litigated and decided in the 2005 case, issue preclusion did not apply. That left claim preclusion as the only possible basis for blocking Lucky Brand. Claim preclusion applies only when two lawsuits involve the same 'claim' — meaning they share a 'common nucleus of operative facts,' such that a judgment in the second suit would threaten or undermine the first.
- The Court compared the two suits' factual cores and found them distinct. The 2005 lawsuit depended on Lucky Brand allegedly using the 'Get Lucky' phrase — Marcel's own registered mark. The 2011 lawsuit, by contrast, was about Lucky Brand's use of its own separate marks containing the word 'Lucky,' with no allegation that Lucky Brand had used 'Get Lucky' at all. Different marks and different alleged conduct mean different operative facts.
- The timing difference reinforced this conclusion. The conduct at issue in the 2011 case occurred after the 2005 case had already ended. Claim preclusion generally does not bar lawsuits based on events that post-date the earlier filing, because new events give rise to new facts and new claims — a principle with special force in trademark law, where marketplace realities such as consumer confusion can shift significantly from year to year.
- Because the two suits lacked a common nucleus of operative facts, claim preclusion did not apply — and therefore no version of 'defense preclusion' could bar Lucky Brand from raising its settlement defense in the 2011 case. The Court also rejected Marcel's reliance on treatises and older precedents, finding they described situations where defenses would have threatened prior judgments, which was not true here.
