TM and SM are unregistered common-law claims you can use freely — TM for goods, SM for services — the moment you start using a mark in commerce. The ® symbol is reserved for marks the USPTO has federally registered; using it before registration is unlawful under 15 U.S.C. §1111.
Use TM (or SM for services) until your USPTO registration certificate arrives, then switch to ® for federal protection.
The ® symbol signals a granted federal right; TM signals only a claim, and using ® before registration is fraud.
Check your trademark status at USPTO.gov before adding ® to any new marketing materials.
The TM symbol is an informal notice that a business is treating a word, logo, or slogan as a trademark for goods, whether or not it is federally registered. TM has no formal legal requirements — anyone may use it at any time — but it strengthens common-law rights by signaling the owner’s intent to claim the mark as a source identifier.[3]
For most small businesses, TM is the correct symbol for a mark that is in commercial use but not yet registered — or never will be. When a federal registration is filed, TM stays in place until the certificate is granted, at which point the symbol switches to ®.
Switch from TM to ® the moment the USPTO grants federal registration and issues a registration certificate for the mark. The ® symbol indicates that the mark is federally registered and protected nationwide under 15 U.S.C. §1114. Using ® before the certificate is issued is illegal and can hurt the pending application.[2]
Retail businesses and e-commerce sellers often miss step 3 — the certificate arrives but the website still shows TM for months. Update every public-facing asset within weeks of registration to lock in the strongest enforcement position.
Yes. Using ® without a valid federal registration is false marking and can seriously hurt both the pending application and future enforcement. A USPTO examining attorney may refuse the application for bad faith, and in court, improper ® use can be introduced as evidence of fraud. Most applicants avoid this easily by sticking to TM until the certificate arrives.
The practical rule: ® is only for marks with a live USPTO registration. Once a registration lapses or is cancelled, remove the ® from all public-facing materials and return to TM.
Place the symbol next to the first or most prominent appearance of the mark on any page, label, or advertisement — not on every instance. The symbol appears as a superscript directly after the mark, with no space or punctuation between. Size is smaller than the mark itself, and the symbol never replaces pairing the mark with a generic term.
| Medium | Placement and frequency |
|---|---|
| Website | Superscript after the mark in the header, hero, or footer — once per major page section |
| Product packaging | Superscript next to the mark on the front panel — once; optional on side panels |
| Advertisements | Superscript at the first or largest use of the mark — once per ad unit |
| Marketing emails | Superscript in the subject line or first body mention — once per email |
| Legal documents | Full symbol at first use, with optional footnote on registration status |
Repetition of the symbol on every occurrence is legally unnecessary and clutters the copy. Courts have consistently held that one prominent use of the symbol per piece gives adequate notice under 15 U.S.C. §1111.
Underlying trademark rights don’t disappear if you omit TM or ®, but your ability to recover certain damages in infringement litigation can shrink significantly. Under 15 U.S.C. §1111, a federal registrant who never uses ® cannot recover lost profits or damages from an infringer unless the infringer had actual notice of the registration.[1]
The practical rule is simple: use ® on registered marks consistently. The symbol costs nothing, gives the maximum enforcement posture, and protects the full financial value of the registration. Inconsistent notice leaves money on the table when infringement happens.
Most founders spend thousands on trademark registration and then forget to finish the job by consistently using the right symbol across their brand assets. The ® you put in your header, on your packaging, in your email signature — that tiny superscript is what turns a registration certificate into an enforceable financial asset. Using the symbol is the last mile of protection, and the symbol itself is free.
The cost asymmetry is striking. A federal registration costs $250–$350 per class plus legal help. A consistent ® program across a website, product line, and marketing costs nothing. The federal statute, 15 U.S.C. §1111, ties monetary recovery in infringement cases directly to proper symbol use. Owners who skip the symbol often discover the limit the hard way when they try to sue a copycat and the court limits them to an injunction without damages.
This is Responsible Asset-Building at its smallest scale: making sure the asset you paid to register actually performs like a registered asset. An educated consumer doesn’t let a $500 filing fee become an unprotected brand because the ® never made it onto the packaging.
Yes — TM has no formal requirements and no registration standard. Any business may use TM next to a word, phrase, or logo it is treating as a source identifier for goods. If the mark later turns out not to qualify (because it's generic or descriptive), the TM use doesn't create additional legal risk. The TM usage simply had no enforceable rights behind it.
It's ®. The ® symbol covers both trademarks and service marks once they are federally registered — there is no separate registered service mark symbol. SM is only used for unregistered service marks. Once a service mark is registered with the USPTO, switch from SM to ® the same way a trademark owner does.
No. The ® symbol is specifically tied to federal registration with the USPTO under 15 U.S.C. §1111. State trademark registrations do not confer the right to use ®. State-registered marks may use TM or SM for the common-law claim, or explicit language like 'Registered in [State].' Using ® with only a state registration is false marking.
Most countries recognize ® as indicating a registered trademark, but the recognition is tied to registration in that specific country. A U.S. federal registration does not authorize ® use in countries where the mark is not separately registered. Using ® in a country where the mark is not registered there can create false-marking exposure under that country's laws.
No — using both is confusing and potentially misleading. Pick one based on registration status: ® if the mark is federally registered and the registration is active; TM (or SM for services) if not. Showing both suggests uncertainty about the mark's status, which weakens the enforcement posture and can be introduced in court as evidence of the owner's own confusion.
