Common Law Trademark Rights vs Federal Registration

The United States has a unique trademark system: rights arise from use, not registration. The moment you use a distinctive trademark in commerce, you have common law trademark rights, no filing required. But those rights come with limits, which is why federal registration is the better choice for most businesses.

Two Paths to Trademark Rights

In the United States, there are two distinct sources of trademark rights:

1. Common law rights: arise automatically from actual use of a trademark in commerce. Indicated by the ™ symbol.
2. Federal registration rights: obtained by registering the trademark with the USPTO. Indicated by the ® symbol.

Both provide some level of protection, but they differ dramatically in scope, enforceability, and strategic value. Any term in this guide that is new to you is defined in our trademark glossary.

Common Law Trademark Rights

Common law rights are automatic. You do not need to file anything. As soon as you use a distinctive trademark in connection with goods or services in commerce, you have rights.

What You Get

• Protection in your geographic area of actual use: if you operate a restaurant in Denver, you have rights in the Denver metropolitan area
• Right to sue for infringement: in state court (and sometimes federal court under Section 43(a) of the Lanham Act)
• Priority over later users: in your geographic area only

What You Do Not Get

• No nationwide priority
• No presumption of validity
• No constructive notice to third parties
• No ability to record with U.S. Customs and Border Protection
• No access to statutory damages
• No path to incontestability
• Limited effectiveness in UDRP domain disputes

Citation: Common law trademark rights derive from state law and the Lanham Act § 43(a), 15 U.S.C. § 1125(a)

Federal Registration Rights

Federal registration with the USPTO provides a bundle of rights that common law cannot match.

What You Get

• Nationwide priority: constructive use from the filing date across all 50 states
• Constructive notice: everyone in the United States is deemed to have notice of your registration
• Presumption of validity: your registration is presumed valid; challengers bear the burden of proof
• Federal court jurisdiction: right to sue in federal court with enhanced remedies
• Customs recording: register with CBP to block infringing imports at the border
• Incontestability: after 5 years, your trademark becomes nearly immune to challenge on most grounds. See Section 15 declarations
• ® symbol: legal right to use the registered trademark symbol
• UDRP effectiveness: strong evidence in domain name disputes
• Amazon Brand Registry: required for enrollment in Amazon's brand protection program. Our Amazon Brand Registry service handles the filing and the enrollment together

Citation: 15 U.S.C. § 1057(b), Constructive Notice; 15 U.S.C. § 1065, Incontestability

Side-by-Side Comparison

The Burger King Problem: A Real-World Lesson

One of the most famous examples of common law vs. federal registration involves Burger King.

A small restaurant in Mattoon, Illinois, opened as "Burger King" in 1959, before the national Burger King chain (Burger King Corporation, founded in Miami in 1954) expanded to Illinois or obtained federal registration.

The result? The Mattoon Burger King has prior common law rights in the Mattoon area. The national chain, one of the largest restaurant brands in the world, cannot use the "Burger King" name within approximately 20 miles of Mattoon.

Pro Tip: This case perfectly illustrates the geographic limitation of common law rights. Without federal registration, your rights stop at the boundary of your actual market presence. A competitor can adopt the same trademark in a market you have not reached yet, and a registration is what lets you plant your flag nationwide first.

When Common Law Rights Are Enough

In practice, very few businesses should rely solely on common law rights. Common law might be sufficient if:

• You operate a purely local business with no expansion plans
• You have no online presence (increasingly rare)
• You have no competitors in other geographic markets
• You are comfortable with someone else being able to register a similar trademark

For the vast majority of businesses, these conditions do not apply. Even a small business with a website is operating in interstate commerce and can benefit from federal registration.

Why Federal Registration Is Worth It

The cost of federal trademark registration starts at $350 per class in government fees paid to the USPTO, and our professional fee is listed on the pricing page. For that investment, you receive:

1. Nationwide protection: your priority date extends across all 50 states
2. Legal presumption of validity: shifts the burden to any challenger
3. Deterrent effect: others searching the USPTO database will see your registration and choose a different trademark
4. Enhanced enforcement: federal court, customs recording, statutory damages
5. Platform eligibility: Amazon Brand Registry, eBay VeRO, and other brand protection programs
6. Incontestability option: available after 5 years of continuous use
