Answer
What rights do I have without registering?
Lawyers call this: common-law trademark rights · 15 U.S.C. § 1125(a)
Short answer
Real ones, but they are local. If you have been using a name to sell goods or services, you own rights in it for those goods, in the area where you actually do business and have a reputation. You can stop a later business from using a confusingly similar name there. Outside that area, and against anyone who used the name before you, those rights are weak or absent.
What changes the answer
- Who used the name first
- In the United States, rights generally go to whoever used the mark first for the goods or services, not to whoever filed first. The law calls this priority.
- Where you actually do business
- Rights from use alone reach the territory where buyers know your brand. A shop known in one city generally has no rights in a city where nobody has heard of it.
- How distinctive the name is
- An invented or unexpected name earns rights as soon as you use it. A name that just describes what you sell earns rights only after buyers come to see it as your brand, and proving that takes evidence.
- Whether someone else registers first
- A later federal registration does not erase your earlier rights. But it can limit how far those rights extend: you may keep superior rights in the territory where you can prove earlier use, while the federal registrant can acquire superior rights elsewhere.
- How much proof you have
- Without a registration, you must prove your rights from scratch — when you started, where you sold, and what buyers know. Dated invoices, ads, and sales records carry that proof.
The rule
The Lanham Act protects unregistered marks as well as registered ones. Section 43(a), 15 U.S.C. § 1125(a), lets the owner of an unregistered mark sue in federal court over a use likely to cause confusion. See Two Pesos, Inc. v. Taco Cabana, Inc., 505 U.S. 763 (1992). State law gives similar protection.
The limit is geography. Under long-standing Supreme Court precedent, a common-law owner’s rights reach the areas where it uses the mark and has a reputation, not the whole country. Hanover Star Milling Co. v. Metcalf, 240 U.S. 403 (1916); United Drug Co. v. Theodore Rectanus Co., 248 U.S. 90 (1918).
A federal registration on the Principal Register changes the picture in several ways:
- Once it registers, the filing date works as nationwide use against everyone except earlier users and earlier filers. 15 U.S.C. § 1057(c).
- It is evidence that the mark is valid and that the owner has the exclusive right to use it for the listed goods or services. 15 U.S.C. § 1057(b).
- It gives nationwide notice of the owner’s claim. 15 U.S.C. § 1072.
An earlier common-law user keeps a defense, but only for the area where it proves continuous use from before the registrant’s filing date. 15 U.S.C. § 1115(b)(5).
At the USPTO, your earlier use can defeat another person’s registration through an opposition or cancellation. It does not, by itself, get your own application past a conflicting registration during examination.
Go deeper
Who owns a mark often comes down to dates — first use, filing date, and where each business was selling. The guide explains how priority is proved and decided.
What to do next
Gather your proof now, while it is easy to find. Keep dated records of first sale, the places you have sold, advertising, and press. That costs nothing and is work you can do yourself.
If the name matters to your business and you sell, or plan to sell, beyond one area, a federal application locks in a nationwide filing date. Many owners with a distinctive name and a clean search file on their own.
If someone else has registered or is using a name close to yours, the facts and dates decide who has the better claim. Valet Law, PLLC can review your records and tell you where your rights stand.
