Someone Else Just Filed Your Brand Name. You've Been Using It for Years. Now What?

BOCA RATON, FL — You built the brand. You used the name. Then someone else filed a trademark application for it. For founders, startups, and small businesses, this can feel like a crisis. But under U.S. trademark law, being first to use a name in commerce can matter more than being first to file with the United States Patent and Trademark Office (USPTO). The key is acting quickly and strategically.

Common Law Rights: Use Builds Real Protection

U.S. trademark rights begin with use, not registration. The moment a business uses a distinctive name to identify its goods or services in commerce, it begins to acquire what attorneys call common law trademark rights. Those rights are geographically limited to the area where the mark is actually known and used, but within that area they are real, enforceable, and senior to anyone who comes later.

If your business has been operating under a name for years — selling products, serving customers, running ads, building a website — you are very likely the senior user of that mark in your market, even if you never filed a trademark application at the USPTO.

Senior User vs. Junior Filer: Why It Matters

When someone else files a federal application for a confusingly similar mark after you began using it, they may be considered the junior user. Federal registration grants powerful nationwide presumptions, but those presumptions may be overcome with evidence of your prior use. A senior user with documented evidence — sales records, dated marketing materials, social media archives, customer testimonials, dated website captures — can stop a junior filer from cementing exclusive rights against them.

Time is the critical factor. Once a federal registration matures, the rights and remedies available to you narrow significantly. The earlier you act, the more options you have.

Three Paths Forward

1. Outreach and Consent.

In some cases, the best first move is a measured letter to the junior filer or their counsel. The goal is not to threaten — it is to put them on notice of your prior use and explore whether the dispute can be resolved without litigation. Outcomes can range from the junior filer abandoning their application, to a coexistence or consent agreement, to a license. Approached correctly, this path is faster, cheaper, more certain, and far less public than a contested proceeding. Approached poorly, it can hand the other side admissions and ammunition. This is one area in which experienced counsel can provide business-specific guidance.

2. Opposition Proceedings.

If the junior filer's application is still pending and has been published in the USPTO's Official Gazette, you have a 30-day window to file a Notice of Opposition with the Trademark Trial and Appeal Board (TTAB). Extensions are available, but only if you properly request one in time. An opposition is a legal proceeding — discovery, briefing, and a final decision — but it is generally less expensive and faster than federal court litigation. A successful opposition prevents the junior user’s application from registering at all, preserving your rights and your leverage.

3. Cancellation Proceedings.

If the junior filer's mark has already registered, you may still be able to seek a Petition to Cancel, a proceeding also filed at the TTAB. Cancellation is available on a number of grounds, including likelihood of confusion with a prior user. For certain grounds, including being the senior user, cancellation of the junior user’s registration must be filed within five years of registration. After that, the mark will likely become incontestable and your options for cancellation shrink dramatically. If a registration that troubles you is approaching its fifth anniversary, time is of the essence.

How to Strengthen Your Position Right Now

Whether or not you face an immediate dispute, every founder and small business owner should take three steps. First, document your use: archive dated screenshots of your website, save social media posts, preserve invoices, advertising, and press mentions. Second, file your own federal trademark application if you have not already — federal registration converts limited geographic rights into nationwide rights and is one of the best protections against this scenario in the future. Third, set up a basic watch for your brand so a future junior filer does not catch you by surprise.
