Common Law Trademark Rights: Why They Matter—And Why Registration Is Even Better

If you've created a unique business name, product name, tagline, or logo and started using it in the marketplace, you may already own valuable common law trademark rights—and you may not even realize it. In fact, gaining a common law trademark is free: you don't need to file anything or pay any government fees to establish your rights.

But while common law trademarks offer important protections, relying solely on them can leave your brand vulnerable as you grow. That's why many business owners turn to services like TrademarkFactory® to turn their common law trademark rights into strong, nationwide protection through official registration.

In this guide, we'll walk you through how to get a common law trademark, the real value of common law rights, the importance of a common law trade mark search, and why securing an official registration of the common law trademark is the best investment you can make in your brand's future.

What Is a Common Law Trademark?

A common law trademark is a right you gain automatically when you use a distinctive name, logo, phrase, or design in connection with your goods or services in the marketplace. No paperwork. No government approval needed. Simply using the brand in commerce establishes your common law trademark rights. Want to know if the rule is universally recognized across the globe? Click here.

For example, if you start selling handmade jewelry under the brand "Sunstone Designs" and promote it locally, you immediately begin building common law rights in that name.

Having a common law trademark free is a great starting point. It allows you to prevent others in your local market from using confusingly similar names or logos.

However, it's important to understand that common law rights are a foundation—not a fortress. As your business expands, those free protections often aren't strong enough to safeguard everything you've worked so hard to build.

How to Get a Common Law Trademark

How to get a common law trademark is simple:

Create a Distinctive Mark
Avoid generic or merely descriptive terms. Choose something unique that customers will associate specifically with your brand.

Use It in Commerce
Your mark must be used on your goods, services, advertising, or packaging—not just sitting on a design file.

Establish Recognition
The more consistently you use the mark, the stronger your common law trademark rights become.

It costs nothing to acquire a common law trademark, but the true value of those rights depends on how you use and protect them—and whether you're prepared to reinforce them through registration.

When to Use TM and ® Symbols

Even if your trademark is not federally registered, you can use the ™ symbol next to your brand to show you're claiming rights under common law. This simple step can deter copycats and strengthen your brand position.
