TM vs ®: which symbol can your AI character use?

Two tiny symbols, two very different meanings. One you can use today. The other you have to earn.

This is an overview, not legal advice. An attorney can confirm what fits your situation.

Step by step

  1. Use ™ (or ℠) any time. The USPTO says you can use “TM” for goods or “SM” for services even if you haven’t filed. It tells people you claim the name. It doesn’t create a registration.
  2. Check the name first. A ™ won’t help if someone already owns a close name. Run the free name check before you build merch around it.
  3. Apply, if it fits. A federal application can be filed on use, or on an intent to use the name later. See intent to use, explained.
  4. Wait for the certificate. Filing isn’t registration. The USPTO examines every application, and nothing is guaranteed.
  5. Then, and only then, use ®. Once your mark is registered, you can use ® — only for the goods or services listed in the registration.
Heads up. Don’t put ® on a name that isn’t federally registered. The USPTO reserves it for registered marks, and misuse can cause legal trouble. When in doubt, use ™.

Which one for a channel or show?

A YouTube, TikTok or VTuber channel is usually an entertainment service, so “SM” is the technically matching symbol before registration. Most creators just use ™, which people recognize. Either one only signals a claim.

Next step

The free name check reads live USPTO records and can tell you not to file. CharacterGuard’s Lock kit ($249 once) gets your name, mark and channel record ready for an attorney. It isn’t a filing, and we don’t file. USPTO and attorney fees are separate. CharacterGuard isn’t a law firm.

Questions

Can I use ™ without filing anything?
Yes. The USPTO says you can use TM or SM even if you haven’t filed an application. It only signals that you claim the name.
When can I use ®?
Only after the USPTO registers your mark, and only with the goods or services listed in that registration. A pending application isn’t enough.
Does ™ protect my AI character’s face?
No. A trademark symbol is about the name or logo as a brand. The U.S. Copyright Office says purely AI-generated images aren’t protected by copyright either.
Do you file for me?
No. CharacterGuard isn’t a law firm and doesn’t file. The free check reads public records, and the Lock kit ($249) gets your name, mark and channel record ready for an attorney.
