You Have Rights. But They're Limited.
If you've been using a brand name in commerce — selling products, performing services, building a business — you have common law trademark rights. No registration required. These rights exist automatically based on your actual use of the name.
But common law rights come with serious limitations that every creator should understand.
What Common Law Rights Give You
When you use a brand name in commerce, you automatically get the right to prevent others from using a confusingly similar name — but only in the geographic area where you actually do business.
If you run a bakery called "Sunrise Sweets" in Portland, Oregon, you have common law rights to that name in the Portland area. Someone can't open another "Sunrise Sweets" bakery across town.
That's the extent of it.
The Limitations Are Significant
Geographic restriction. Your protection extends only to the area where you have actual customers. A bakery in Portland has no common law claim against "Sunrise Sweets" in Miami.
Burden of proof. With a federal registration, your ownership is presumed. With common law rights, you have to prove everything — first use date, geographic reach, consumer recognition. This means keeping detailed records of every sale, advertisement, and customer interaction.
Hard to enforce. Common law claims are expensive to litigate and hard to win. You need to prove the other party's use is causing actual confusion in your specific market. Without registration, you can't sue in federal court or collect statutory damages.
No nationwide protection. This is the biggest gap. Someone in another state can register your exact brand name as a federal trademark and gain nationwide rights — potentially forcing you to stop using the name you started with.
No customs protection. You can't record common law marks with U.S. Customs to prevent importation of counterfeit goods.
When Common Law Rights Matter
Common law rights aren't worthless. They matter in specific situations:
- Local businesses that operate in a defined geographic area and don't plan to expand nationally
- Priority disputes where you can prove you used the name first in your area
- Defense against infringement — if someone sues you, your prior common law use can be a valid defense in your geographic market
- Interim protection while your federal application is pending (the USPTO process takes 8-12 months)
When They're Not Enough
If any of these apply to you, common law rights alone won't cut it:
- You sell products online (your market is national, not local)
- You plan to expand to other cities or states
- You have a growing social media presence (your audience is everywhere)
- You want to license your brand or enter partnerships
- You want to be able to send enforceable cease and desist letters
For creators and digital brands, common law rights are almost never sufficient. Your audience is national from day one.
The Smart Play
Use common law rights as a bridge, not a destination. Start building your brand, but file for federal registration early. The $350 filing fee buys you nationwide protection, legal presumption of ownership, and the ability to enforce your rights in federal court.
