Trademark Symbols ®, ™, ℠: The Complete Guide (When and How to Use Each)

Three small characters carry very different legal weight. The registered trademark symbol ® is the only trademark notice expressly authorized by the federal Lanham Act (15 U.S.C. § 1111), and using it before your mark is federally registered with the U.S. Patent and Trademark Office is a misrepresentation that can torpedo an infringement claim. Use it correctly after registration and you preserve the right to recover profits and damages without having to prove the defendant had actual notice of the registration.

™ and ℠ sit on the other side of the line. The USPTO confirms you can use TM for goods or SM for services even before filing an application — these symbols signal a common-law claim, not a federal right.

Here is the at-a-glance breakdown:

The rest of this guide covers what each trademark symbol legally means, when you are allowed to use each one, how to type ®, ™, and ℠ on Mac, Windows, iOS, Android, and the web, where to place them in copy and how often, and the six mistakes founders make most often.

® — The Federal Registration Symbol

The ® symbol means one specific thing: the mark next to it is registered with the United States Patent and Trademark Office. Not pending. Not allowed. Not state-registered. Issued. Until the USPTO mails the registration certificate, the ® is off-limits — even if your application has cleared examination, published for opposition, or received a Notice of Allowance.

The rule comes straight from the examiner's playbook. TMEP § 906 states that “the federal registration symbol may not be used with marks that are not actually registered in the USPTO. Even if an application is pending, the registration symbol may not be used until the mark is registered. Registration in a state of the United States does not entitle a person to use the federal registration notice.” So a Texas state trademark, a pending Madrid filing, or a common-law brand you've used since 2019 does not earn you an ®.

The flip side matters just as much: once you do have a registration, using the ® is how you preserve your full damages remedy. Under Lanham Act § 29 (15 U.S.C. § 1111), a registrant who omits the notice cannot recover profits or damages in an infringement suit “unless the defendant had actual notice of the registration.” Translation — if your product page, packaging, and SaaS dashboard all run the mark naked, an infringer can argue you forfeited the monetary recovery for the period before they were formally notified.

Misuse cuts the other direction too. Deliberately slapping ® on an unregistered mark with intent to deceive the public or the USPTO is treated as fraud and can support cancellation of the underlying registration (Copelands' Enterprises, Inc. v. CNV, Inc., 887 F.2d 1065 (Fed. Cir. 1989); see also TMEP § 906.02). Honest mistakes — printer error, confusing ® with the copyright symbol, an expired registration nobody flagged — generally are not fatal, but the safer move is to audit before you ship.

One scope rule founders routinely miss: per the USPTO, “you may only use the registration symbol with the trademark for the goods or services listed in the federal trademark registration.” If your registration covers downloadable software and you launch a hardware accessory under the same name, the ® does not travel with the brand into the new class.

™ — The Unregistered Trademark Symbol

The ™ symbol is the do-it-yourself option. It signals that you are claiming a word, phrase, logo, or design as a brand identifier for goods, and it requires no government approval to use. The USPTO confirms this directly: you can use “TM” for goods or “SM” for services even if you have not filed an application to register your trademark. The Trademark Manual of Examining Procedure says the same thing — TMEP § 906 permits descriptors like “TM,” “SM,” and “trademark applied for” regardless of registration status. Only ® is restricted.

That means ™ is appropriate at every stage before a federal registration certificate issues: before you ever file, while a use-based application under Section 1(a) is being examined, and while an intent-to-use application under Section 1(b) is pending or sitting on a Notice of Allowance. Do not jump to ® when you receive a Notice of Allowance or when your mark publishes for opposition. Wait for the certificate.

Common-law rights backed by ™ are real, but they are geographically fragile. The Supreme Court held more than a century ago that trademark rights attach to a business and are limited to the territory where the mark has actually been used (Hanover Star Milling Co. v. Metcalf, 240 U.S. 403 (1916)). A good-faith junior user who adopts the same mark in a remote market the senior user never reached can keep that market for themselves (United Drug Co. v. Theodore Rectanus Co., 248 U.S. 90 (1918)) — the doctrine known as Tea Rose-Rectanus.

The practical consequence: if you sell coffee in Austin under BLUEBIRD™ and a Brooklyn café independently launches BLUEBIRD coffee a year later, you both have enforceable rights — in your own territories. Neither of you can shut the other down. Federal registration is what closes that gap.

℠ — The Service Mark Symbol

℠ is the service-mark twin of ™. Same legal status, same common-law function, same lack of registration requirement — the only difference is what it sits next to. Use ™ when your mark identifies goods (a physical product, a downloadable file, a bottle of soda). Use ℠ when your mark identifies services (consulting, hosting, repair, delivery, software-as-a-service). The Lanham Act defines a service mark in language parallel to a trademark, substituting "services" for "goods" and otherwise leaving the analysis identical (15 U.S.C. § 1127).

The line between goods and services is where founders trip. "Coca-Cola" on a can sells a good — ™ territory. "Geek Squad" sells in-home tech help — ℠ territory. A SaaS company is selling a service for trademark purposes even though customers interact with software, because what's being delivered is ongoing access and support, not a copy of a program. If you ship a boxed product and run a subscription platform, you may have both a trademark and a service mark riding on the same brand name.

One thing the USPTO does not do is provide a separate registered service-mark symbol. TMEP § 906 recognizes only three forms of federal registration notice — the long-form phrase, the "Reg. U.S. Pat. & Tm. Off." abbreviation, and ®. There is no ®S. Once you're registered, ® covers both.

Here's the practical truth: many service businesses use ™ anyway, and the USPTO's own guidance permits either. ℠ is technically more precise for a pure-services brand, but the legally meaningful line is between using a symbol and using none at all — not between ™ and ℠.

Registered vs. Unregistered Trademarks: What Founders Need to Know

Common-law trademark rights arise the moment you use a distinctive mark in commerce. No filing, no fee, no waiting. Section 43(a) of the Lanham Act (15 U.S.C. § 1125(a)) lets the owner of an unregistered mark sue in federal court whenever a competitor's use is likely to cause consumer confusion. That is real enforcement power, and it is why the ™ symbol carries weight even without a certificate.

Federal registration under Section 32 (15 U.S.C. § 1114) layers a second, stronger regime on top. Registrants get nationwide constructive notice of ownership, a legal presumption of validity, the right to record the mark with U.S. Customs and Border Protection to block infringing imports, eligibility to display ®, treble damages and attorney's fees in exceptional infringement cases, and a filing base for international protection through the Madrid Protocol. After five years of continuous post-registration use, the mark can become incontestable (15 U.S.C. § 1065).

So why do so many startups sit on ™ for a year or more? Cost and time. Effective January 18, 2025, the USPTO collapsed the old TEAS Plus and TEAS Standard tiers into a single base application fee of $350 per class, plus surcharges for free-form goods identifications and missing information. The agency's Trademarks Dashboard currently targets first-action pendency at five months and total pendency at roughly eleven months, so the gap between filing and a usable ® is most of a year.

The pragmatic founder framework: use ™ from day one of brand launch, file an Intent-to-Use application under Section 1(b) as early as the brand is reasonably locked, and switch to ® the moment registration issues. For a step-by-step walkthrough, see our guide to the USPTO trademark application process.

How to Type ™, ®, and ℠ on Every Platform

The three symbols share stable Unicode code points that work in any modern application that accepts hex entry. Where they diverge is in OS-level keyboard shortcuts: ℠ is the awkward case on every platform because it sits outside the legacy Windows-1252 code page and Apple's default Option-key set. The table below covers the universal fallbacks first, then the platform-specific shortcuts.

Microsoft Word

Word's default AutoCorrect converts (c), (r), and (t) enclosed in parentheses to ©, ®, and ™ as soon as you type them. The dedicated shortcuts are Ctrl+Alt+T for ™ and Ctrl+Alt+R for ®. To disable or edit these substitutions, open File > Options > Proofing > AutoCorrect Options. ℠ is not in the default AutoCorrect list — insert it via Insert > Symbol, or type 2120 followed by Alt+X.

Google Docs

Google Docs does not auto-convert (TM) or (R) to symbols by default. Use Insert > Special characters and search by name ("trademark," "registered," "service mark") or by code point. To enable autocorrect-style conversion, go to Tools > Preferences > Substitutions and add your own mappings (for example, (tm) → ™).

Mobile (iOS and Android)

• iOS: Long-press R on the alphabetic keyboard for ®. For ™ and ℠, switch to the Symbols keyboard and long-press the relevant key, or rely on predictive text — typing (tm) or (r) typically surfaces the symbol as a suggestion.
• Android: Long-press R for ® and T for ™ on Gboard and most stock keyboards. For ℠, use the emoji/symbols keyboard and search "service mark."

HTML and Web

For source legibility, use the named entities ™ and ®. Because there is no named entity for ℠, use the numeric reference ℠ or hex ℠. All three render reliably in modern browsers without a fallback font.

Accessibility

Screen reader pronunciation varies by engine and verbosity setting — the most common announcements are "TM," "registered trademark," and "service mark," but some readers skip the symbols entirely at default verbosity. For logos and brand marks where the symbol carries legal meaning, add an aria-label on the containing element (for example, aria-label="Acme, registered trademark") so the announcement is predictable across assistive technologies.

Placement, Style, and Frequency Conventions

The difference between amateur copy and brand-mature work usually shows up here. The symbol is correct; the typography around it is sloppy. Once you know the conventions, your collateral starts to look like it was reviewed by counsel even when it wasn't.

Where to put the symbol

The USPTO's guidance is permissive: you may place the registration symbol anywhere around the mark, although most owners use it as a superscript or subscript to the right. Top-right superscript is the dominant convention; bottom-right baseline is also acceptable, particularly with logos that have visual weight at the top. Pick one placement and use it consistently across the brand system. TMEP § 906 governs the form of the notice itself (long-form, abbreviation, or ®) but does not dictate exact pixel placement.

How often

Nothing in the Lanham Act requires the symbol on every appearance of the mark within a single document. The widely accepted industry convention — though not codified in the Lanham Act or TMEP — is to mark the first or most prominent use in any document, then optionally once per major section, and to include a small legend at the bottom such as: "® Registered trademark of [Owner]; ™ Trademark of [Owner]." Marking every instance is permitted but visually noisy and reads as inexperienced.

Use the mark as a proper adjective — and avoid genericide

This is the rule that separates brand-mature copy from copy that endangers the mark. Use the trademark as a proper adjective followed by the generic noun, exactly as registered. Write "Velcro® brand fasteners," not "a velcro." Write "Kleenex® tissues," not "a kleenex." Never let your own materials use the mark as a noun, plural, possessive, or verb.

The cautionary history is brutal. Bayer lost "Aspirin" as a consumer trademark when Judge Learned Hand found the term had become the generic name for acetylsalicylic acid (Bayer Co. v. United Drug Co., 272 F. 505 (S.D.N.Y. 1921)). Four decades later, the Second Circuit held that "thermos" had become generic and let competitors use the lower-case word, faulting King-Seeley's own marketing for promoting "Thermos bottle" instead of "Thermos vacuum-insulated bottle" (King-Seeley Thermos Co. v. Aladdin Industries, 321 F.2d 577 (2d Cir. 1963)).

Modern marks live in the same risk zone:

• Google — routinely used as a verb ("I'll google it"). Google survived a 2017 cancellation challenge because the Ninth Circuit held that verb use alone does not establish genericide; the test is whether the mark's primary significance to the relevant public is the product type rather than the source.
• Photoshop — used as a verb ("photoshop the image"). Adobe's style guide pushes hard against this for a reason.
• Velcro and Kleenex — used as standalone nouns for hook-and-loop fasteners and facial tissues generally.

The lesson is operational: in your own marketing, product copy, and packaging, treat the mark as an adjective, capitalize it as registered, and pair it with the generic noun. You cannot control how customers speak, but you can control how your brand speaks about itself — and that record is what a court will look at first.

Six Mistakes Founders Make With Trademark Symbols

Most symbol misuse falls into a small set of repeat offenders. The USPTO catalogs them itself in TMEP § 906.02, and the worst-case version, deliberate misuse with intent to deceive, can support cancellation of the underlying registration under Copelands' Enterprises, Inc. v. CNV, Inc., 887 F.2d 1065 (Fed. Cir. 1989). Here are the six that founders trip over most.

1. Using ® before the certificate issues. TMEP § 906 is explicit: "Even if an application is pending, the registration symbol may not be used until the mark is registered." That includes the window after a Notice of Allowance and during the Statement of Use. Copelands holds that doing this with intent to deceive can be fraud and a basis for cancellation. Use ™ until your registration certificate is in hand.
2. Continuing to use ® on a dead registration. Miss your Section 8 affidavit between years 5 and 6, or your combined Section 8 and 9 at year 10, and the registration is canceled. TMEP § 906.02 lists expired and canceled registrations among the most common improper-use scenarios. Calendar your maintenance deadlines and revert to ™ immediately if a registration lapses.
3. Marking the descriptive part of the mark. If you registered PROMISE standalone, ® belongs on PROMISE, not on "PROMISE LEGAL." TMEP § 906.02 flags applying the symbol to part of a mark, or to different goods than those registered, as improper. Match the symbol to exactly what is on the certificate.
4. Letting design strip notice symbols for visual cleanliness. The USPTO is clear that you may only use ® "with the trademark for the goods or services listed in the federal trademark registration" — and conversely, under 15 U.S.C. § 1111, omitting the notice means you cannot recover profits or damages from an infringer for the period before they had actual notice of your registration. Brand teams routinely delete ® from logos for kerning reasons. Require legal sign-off before any notice symbol is removed from a primary asset.
5. Treating a state registration as if it were federal. TMEP § 906 states it directly: "Registration in a state of the United States does not entitle a person to use the federal registration notice." A Texas Secretary of State trademark registration, or any state filing, supports ™ or ℠ only. ® requires a live USPTO registration under the Lanham Act, 15 U.S.C. § 1052.
6. Forgetting your owned digital surfaces. As a practical matter, notice on the website alone is rarely enough. Mark your App Store and Google Play product titles, your Amazon, Etsy, and Shopify listings, packaging artwork, email signatures, and social media bios. Each of those is a place a competitor or infringer will see your mark, and consistent marking strengthens your enforcement posture.

Actionable Next Steps

Here is a checklist you can run this week. Each step is pinned to a concrete authority or workflow so you are not guessing.

1. Audit your current marks. List every name, logo, and tagline you use in commerce, then check each one's status in the USPTO's TESS and TSDR databases. Confirm the registration is live, in your entity's name, and covers the goods or services you are actually selling. Marks tied to expired or cancelled registrations are flagged by TMEP § 906.02 as improper uses of the ® symbol.
2. If you are using ® without a current federal registration certificate, switch to ™ today. This is the single highest-risk fix in the audit. Update files, templates, and live pages in that order.
3. Add notice symbols everywhere your brand appears. Website header and footer logos, packaging, product detail pages, marketing PDFs, pitch and sales decks, and email signatures. Consistent notice strengthens your record of use and puts third parties on notice.
4. File a USPTO application for any brand-critical unregistered mark. Federal registration unlocks the § 1114 remedies, including treble damages in counterfeit cases and attorney's fees in exceptional cases, that common-law owners cannot reach. Total USPTO pendency currently averages about 11 months, so plan to use ™ throughout prosecution. Start with How to Trademark a Name, Logo, and Phrase.
5. Calendar your renewal deadlines. Federal registrations require a § 8 declaration between years 5 and 6 (15 U.S.C. § 1058) and a combined § 8/§ 9 renewal between years 9 and 10 (15 U.S.C. § 1059).
