Common-law rights arise automatically from genuine commercial use of a mark in commerce. The rights extend to the specific geographic area where the business actually operates but don't grant nationwide priority, federal court access, or the legal presumptions that come with federal registration. Common-law rights are real protection but narrower than registered rights.
Use TM or SM on unregistered marks to claim common-law rights, and document commercial use carefully to support any future registration.
Common-law rights are automatic but narrow; documentation strengthens them and supports later federal registration if pursued.
Start using TM or SM on your mark in commerce immediately; keep records of first use dates and continuous commercial activity.
Common-law rights arise from bona fide commercial use of a mark in commerce. The use must be genuine — actual sales or services in the ordinary course of business, not staged transactions designed to create the appearance of commercial activity.
Common-law rights begin the moment bona fide commercial use starts and strengthen with continued use over time. No filing, registration, or government action is required to establish these rights — they’re automatic consequences of genuine commerce under a distinctive mark.[1]
Common-law rights are limited to the specific geographic area where the business actually operates. The rights don’t automatically extend beyond the territory of actual commerce, which is the primary difference from federal registration’s nationwide rights.
A restaurant in Portland, Oregon has common-law rights throughout Portland and likely throughout Oregon. Whether the rights extend to Seattle, Washington depends on whether the restaurant has operations, reputation, or natural expansion potential into Washington. Common-law rights typically don’t extend to distant states where the business has no presence.[2]
Common-law rights provide real but limited protection. Understanding what common-law rights enable helps decide whether they’re sufficient for your specific situation.
For businesses with genuinely local operations and no growth plans, common-law rights provide adequate protection. For businesses with any interstate activity or expansion plans, common-law rights are insufficient and federal registration is the meaningful protection.
Documentation of common-law rights matters for several reasons: supporting later federal registration applications, providing evidence in enforcement actions, and establishing priority dates against competing users. Specific records are worth maintaining.
These records can support later federal registration through Section 2(f) acquired distinctiveness claims, defend against infringement claims by other parties, and establish priority in opposition or cancellation proceedings. For most businesses, creating and maintaining these records is a minor operational task that pays dividends when trademark issues arise.[3]
Common-law rights work for specific scenarios but have significant limitations for most growing businesses. Specific triggers suggest it’s time to upgrade to federal registration.
For most growing businesses, these triggers arrive within the first 1-3 years of operation. Upgrading to federal registration before the triggers arrive provides proactive protection rather than reactive response. The cost of federal registration is modest relative to the value of the expanded rights it provides.
Common-law rights provide automatic baseline protection from commercial use, which is genuinely valuable. A business using a distinctive mark in commerce has rights even without filing anything, and those rights can be enforced against local infringers. This protection matters.
But common-law rights are the floor, not the ceiling. They’re narrower than federal registration in geographic scope, weaker in legal presumptions, and less accessible through federal courts. For businesses that plan to grow, use the internet, or reach beyond a single geographic area, common-law rights alone are insufficient protection.
The right approach for most businesses is using common-law rights as the starting point while moving toward federal registration as the meaningful long-term protection. Common-law rights from initial commercial use establish priority and protection during the pre-federal period; federal registration then provides the nationwide rights that match the business’s actual or planned commercial scope. An educated consumer values common-law rights for what they are — automatic, real, but limited — and files federally when the business’s scope warrants nationwide protection.
Yes, typically through state court. Common-law rights support state-law infringement claims and common-law unfair competition actions. Federal court access generally requires federal registration, though the Lanham Act's false designation of origin provisions at 15 U.S.C. §1125(a) can sometimes support federal court claims for unregistered marks in specific circumstances.
Rights begin with the first bona fide commercial use. Strength increases with continued use over time. After 1-2 years of consistent commercial use, common-law rights are typically well-established in the geographic area of operation. Longer use and broader recognition continue to strengthen the rights, supporting eventual Section 2(f) acquired distinctiveness claims for federal registration.
Scope is fact-specific. E-commerce and online services can extend common-law rights beyond the business's home state when actual sales or service delivery reaches customers across state lines. The exact geographic scope depends on where actual commerce has occurred, how broadly marketing reaches, and whether customers in various areas recognize the mark. Online common-law rights are generally narrower than federal registration's clear nationwide scope.
No formal renewal required, but continued commercial use is essential. Common-law rights depend on ongoing bona fide use; extended gaps in commerce can be treated as abandonment under 15 U.S.C. §1127's standard of three consecutive years of non-use with no intent to resume. Maintain continuous commercial activity to preserve common-law rights.
Possibly, which is a risk of relying solely on common-law rights. A later party can file federal registration for your mark if they don't know about your prior use. If you have documented prior use, you can oppose their application or seek cancellation of their registration. However, the litigation costs are substantial and the outcome uncertain. Federal registration by you avoids this risk.
TM (for goods) and SM (for services) are symbols you can use to claim common-law trademark rights. Using TM or SM doesn't create common-law rights — those arise from commercial use itself. The symbols simply signal your claim. The ® symbol is different and requires federal registration; using ® without registration is prohibited. Use TM or SM with unregistered marks; switch to ® only after federal registration.
