Someone Is Using My Trademark. What Are My Options?

You find it on a Tuesday. Same name, or close enough, selling something close enough to what you sell.

The two options that come to mind are usually the two worst ones: do nothing, or call a lawyer and sue. There's a lot of ladder between those rungs, and most of it is cheap. Here's the sequence, in the order it usually makes sense. For help with a live conflict, see our trademark practice.

First: is it actually a problem?

Not every similar name is infringement. The question isn't whether two words overlap — it's whether ordinary buyers would likely be confused about who they're dealing with. That generally requires a genuinely similar mark, related goods or services, and real potential for confusion.

Somebody using a similar name in a completely different lane often isn't a problem worth spending money on. Trademark rights live within the goods and services you actually claim.

Worth being honest with yourself here, because the ladder gets expensive if you climb it over something that wasn't infringement.

The ladder, cheapest first

Document it. Screenshots with dates, listing URLs, the earliest use you can find of theirs, and proof of your own prior use. Do this before you contact anyone — evidence has a way of disappearing once someone knows you're looking.

Platform takedowns. If it's on Amazon, Etsy, eBay, Meta, or TikTok Shop, each runs its own brand-protection process. A federal registration makes these dramatically faster — it turns an argued complaint into a routine one. This is the highest-leverage step for most online sellers and it costs nothing but time.

A short letter. Not every dispute needs a formal cease-and-desist with litigation threats. Plenty of infringement is accidental — someone picked a name without searching. A measured letter resolves a surprising share of these, and it preserves the relationship in a way a scorched-earth demand doesn't.

Formal cease-and-desist. When the informal approach fails or the conduct is clearly deliberate. Worth having counsel draft it: a poorly-aimed demand letter can create problems, including a declaratory judgment action filed against you.

USPTO proceedings. If they've applied to register, you have options that don't require court. A Letter of Protest during examination, an opposition after publication, or a cancellation if the mark already registered. All materially cheaper than litigation.

Litigation. Real, sometimes necessary, and the most expensive rung. Most conflicts resolve before this.

The part people get wrong

Doing nothing has a cost. Trademark rights weaken when they aren't policed. Let enough people use a confusingly similar name and your mark gets harder to enforce against anyone — including the one you actually care about later.

Overreacting has a cost too. Aggressive demands over weak claims generate backlash, sometimes public, and courts have little patience for trademark bullying. The goal is proportionality, not volume.

Registration changes everything. Nearly every rung on this ladder works better, faster, and cheaper with a federal registration behind it. Common-law rights are real but thin, and they put you in the position of proving what a registration would simply establish.

When to call ELN

The right rung depends on who they are, what they're selling, whether they've filed anything, and how strong your own position is. Those are quick questions to answer with counsel and expensive ones to guess at. If someone is using your name, get it assessed before you send anything — the first message you send shapes everything that follows. ELN Law handles trademark enforcement for creators, founders, and Michigan businesses. Reach out through our trademark practice or schedule a consultation.
