Here’s a scenario that plays out constantly: someone builds a website or app, picks a name that sounds great, registers the domain, and starts working. They never checked whether that name — or something close to it — was already a registered trademark. Then one day they get a legal notice. Suddenly they’re looking at a federal lawsuit, possible damages, and being forced to hand over the domain they paid for and built on.
And yes, this can happen even if you never made a single dollar from it.
According to the U.S. Patent and Trademark Office, if a trademark owner wins an infringement case against you, the available remedies aren’t small. A court can order you to stop using the name immediately. They can require you to destroy any materials that use it. And they can go after monetary relief — including the trademark owner’s lost profits, any damages they suffered, and the costs of the whole legal action. That last part means even the legal fees from fighting you can land on your tab.
The case doesn’t even have to start in federal court. It can start in state court — and if it does, it may be possible for the defendant (that’s you) to have the case “removed” to federal court. Federal court is serious. This isn’t small claims.
What makes it trickier is that trademark law isn’t just about copying someone exactly. Even a name that’s similar enough to create a likelihood of confusion with an existing trademark can be enough to get you sued. You don’t have to be intentionally copying anyone. Accidental infringement is still infringement.
Nolo points out something important here too: even when a company owns a federally-registered trademark, that doesn’t automatically mean they own the matching domain name. Someone else might have registered it first and have legitimate rights to keep it — the law isn’t always as simple as “they have the trademark, so they win.” But that nuance doesn’t make the fight cheap or easy. Even winning a case you’re in the right about costs time, stress, and often lawyer money you don’t have.
The Berkman Klein Center has documented cases where companies sue domain name holders even when there’s been no actual infringement or dilution — just because the domain name relates to something they feel they own. Some of those suits get thrown out. But getting there is a whole ordeal.
So what do you actually do before you launch? Search the USPTO trademark database before you fall in love with a name. Google it. Check app stores. If your name is close to anything a real company uses — especially in the same space — that’s a risk worth taking seriously before you spend months building on it.
