The short version: TM means you're claiming a brand as yours, and you can use it without registering anything; the ® symbol means the mark is registered, and you can only use it once registration is done. The US Patent and Trademark Office says this directly, and GOV.UK and IP Australia both list the right to use ® as something you get from registering.
I see the ® symbol stuck on brand-new logos all the time, usually because it looks more official. It's one of the easiest mistakes to avoid once you know the difference. This is general information from the official trade mark offices, and their pages always govern.
Two symbols, two very different claims
Both symbols tell people a word, logo or slogan is being used as a brand. The difference is what sits behind the claim.
TM is a statement of intent. The USPTO says you can use TM for goods, or SM for services, even if you haven't filed an application to register. It's you saying, publicly, that you see this name as your brand. As the USPTO puts it, the symbol lets consumers and competitors know you're claiming the trademark as yours.
The ® symbol is a statement of fact. The USPTO's instruction is to use ® with your trademark once you've registered it with them. That's the line: no registration, no ®.
What the three trade mark offices say
| Country and office | What it says | The detail people miss (as of Nov 2026) |
|---|---|---|
| US, USPTO: TM | You can use TM for goods even if you haven't applied to register | Costs nothing and needs no filing |
| US, USPTO: SM | You can use SM for services even if you haven't applied to register | SM is the service version; many service businesses don't know it exists |
| US, USPTO: ® | Once your trademark is registered with the USPTO, use ® with it | Only once registered, and only with the mark that's registered |
| UK, GOV.UK | After registering, you can put the ® symbol next to your brand to show it's yours and warn others off | A UK trade mark lasts 10 years |
| Australia, IP Australia | Registration gives you the legal right to place ® next to your trade mark | Trade marks can be registered or unregistered; registration lasts up to 10 years before renewal |
The catch: ® is a reward for registering, not a design choice
Here's the part people get wrong. All three offices treat the ® symbol as something you earn by registering. The USPTO says to use it once your mark is registered. GOV.UK lists putting ® next to your brand among the things you can do after you've registered a trade mark. IP Australia lists the legal right to place ® next to your trade mark as one of the benefits of registration.
Put those together and the message is simple. If your application is still pending, or you've never applied, TM is the symbol for you. Using ® before you're registered is claiming a status you don't have, and that's a risky thing to put on every product, invoice and web page.
There's a second catch for Australian businesses. IP Australia flags a common mistake: thinking that registering a business name gives you exclusive rights to it. It doesn't. If you trade under a name other than your own, you'll need to register that business name with the Australian Securities and Investments Commission, but that's a separate thing from a trade mark.
What registering gets you beyond the symbol
The symbol is the visible part, but it's not the main prize. IP Australia lists the benefits of a registered mark as the legal right to use ®, exclusive rights to use the mark in Australia, more ability to legally deter others from using it, and the ability to sell it or license it to others.
GOV.UK makes a similar point for the UK: once registered, you can sell and license your brand as well as using ®. It also suggests you check two things before applying: that a trade mark is the right type of protection for your intellectual property, and what you can register as a trade mark. If you're still at the naming stage, my guide on choosing a brand name that works helps with the first question.
How to use the right symbol, step by step
- Decide which names, logos or slogans you're using as brands.
- Start using TM for products or SM for services straight away, if you're in the US. No filing is needed for that.
- Check whether a trade mark is the right protection for what you want to protect, as GOV.UK suggests.
- Apply to register in each country you trade in. My step-by-step guide to trademarking a business name walks through it.
- Keep using TM while you wait. IP Australia says registration takes at least 7 months there.
- Switch to ® only once registration is confirmed, and only on the exact mark you registered.
- Diary your renewal: a UK trade mark lasts 10 years, and an Australian one lasts up to 10 years before renewal.
Logos, artwork and symbols
If you've just had a logo made, the same rule applies: TM is fine from day one, ® waits for registration. If you designed it yourself with one of these free logo makers, check the tool's terms before you try to register it, because you'll need to be sure the design is yours to claim.

My verdict
Use TM or SM from the day you launch; it needs no filing, and it tells people you're serious about your brand. Save ® for the day your registration comes through, and put it only on the mark that's registered. That one habit keeps you on the right side of all three offices. When registration day comes, trademark registration services are worth comparing first.

Frequently asked questions
What's the difference between TM and the ® symbol?
TM claims a brand as yours without any registration. The ® symbol shows the mark is registered, and the USPTO says to use it only once your trademark is registered.
Can I use TM without registering?
Yes. The USPTO says you can use TM for goods or SM for services even if you haven't filed an application to register.
Can I use ® while my application is pending?
No. The USPTO, GOV.UK and IP Australia all link the ® symbol to a registered mark, so keep using TM until registration is confirmed.
What does SM mean on a brand?
SM is the service mark symbol. The USPTO says you can use it for services, the way TM is used for goods, without filing an application.
How long does a UK trade mark last?
GOV.UK says a trade mark lasts 10 years, as of Nov 2026.
Does registering a business name give me trademark rights?
Not in Australia. IP Australia lists believing a business name registration gives exclusive rights as a common mistake; a trade mark is separate.
