In-N-Out Burger v. Smashburger
In-N-Out Burgers v. Smashburger IP Holder LLC · 2019 · C.D. Cal.
What happened
In-N-Out challenged Smashburger's "Triple Double" naming against its own "Double-Double" and related family of marks.
The money
No reliable public figure. This dispute matters for the rule it settled rather than for a damages number, and many trademark matters resolve on confidential terms.
What it means for your business
Owning a family of related marks strengthens your position against a new entrant using the same pattern. Conversely, if a competitor has a naming family, borrowing its structure is risky even when no single name is copied.
