TM vs. ®: What the Trademark Symbols Really Mean

TL;DR: The ™ symbol signals an unregistered trademark claim and can be used at any time, while the ® symbol confirms federal registration with the USPTO and provides nationwide legal protection. Using the ® symbol before your trademark that is officially registered is illegal.

Every brand has a name, a logo, or a slogan worth protecting. But knowing how to protect it starts with understanding the symbols attached to it. The ™ and ® symbols appear everywhere — on product packaging, websites, and logos — yet most business owners don’t know what separates one from the other. Get it wrong, and you could be leaving your brand exposed, or worse, breaking the law.

Here’s a clear breakdown from the intellectual property attorneys at Emerson Thomson Bennett of what each trademark symbol means, the legal weight it carries, and when to use it.

What Does the ™ Symbol Mean for Unregistered Trademarks?

The ™ symbol stands for “trademark.” Attaching it to your brand name, logo, or slogan signals to the public that you’re claiming ownership of that identifier for goods — even without formal registration.

• Legal weight: The ™ symbol relies on common law rights. That means your protection is limited to the geographic area or specific market where you actively use the mark. There’s no nationwide coverage, and enforcement can be difficult.
• When to use it: You can start using ™ at any time — before, during, or after filing an application with the United States Patent and Trademark Office (USPTO). No approval is required. For businesses in the early stages of building a brand, ™ serves as a visible warning to potential infringers while your registration is pending.

What Does the ® Symbol Mean for Federally Registered Trademarks?

The ® symbol means your trademark has been officially approved and registered with the USPTO. This is a significant legal milestone.

• Legal weight: Federal registration grants you nationwide protection, legal presumption of ownership, and the right to sue for damages in federal court. These are protections that ™ simply cannot offer.
• When to use it: You may only use the ® symbol after your registration certificate has been officially granted. Using ® before that point is illegal and can jeopardize your registration entirely. Once approved, using ® consistently reinforces your federal rights and puts the public on notice.

Other Related Trademark Symbols: SM and ©

Two more symbols are worth knowing:

• ℠ (Service Mark): The ℠ symbol functions identically to ™ but applies specifically to services rather than physical products. A consulting firm, accounting practice, or marketing agency would use ℠ rather than ™ to claim unregistered rights to their brand.
• © (Copyright): Copyright is an entirely separate form of intellectual property protection. Rather than protecting brand identifiers, © covers original works of authorship — books, music, art, and software. A brand name cannot be copyrighted, but the artwork in a logo might be.

Protecting Your Intellectual Property: Next Steps for Business Owners

Here’s the short version: use ™ (or ℠) to signal your claim early and protect your brand while you build it. Pursue federal registration with the USPTO when you’re ready to secure nationwide rights — and only switch to ® once that registration is confirmed.

Getting the symbols right is step one. Enforcing your rights is another matter entirely.

Frequently Asked Questions

Can I use ® before my trademark is registered?

No. Using the ® symbol before your trademark is officially registered with the USPTO is illegal and can harm your registration application. Use ™ until registration is confirmed.

What’s the difference between ™ and ℠?

Both signal unregistered trademark claims, but ™ is used for goods (physical products), while ℠ is used for services such as consulting, accounting, or marketing.

Does using ™ give me legal protection?

Using ™ establishes common law rights, which limit protection to your geographic area or specific market. It does not provide the nationwide legal protection that federal registration and the ® symbol offer.

How long does it take to register a trademark with the USPTO?

Trademark registration timelines vary, but the process typically takes between 8 and 14 months, depending on whether any issues arise during examination.

Is copyright the same as a trademark?

No. Copyright (©) protects original creative works like books, music, and art. Trademarks protect brand identifiers — names, logos, and slogans. They are distinct forms of intellectual property protection.
