A trademark clearance search before you name an Amazon brand has two parts. First, search the free USPTO trademark database for marks that look, sound, or mean something similar to your name on related goods, not just identical names in your own class. Second, search state trademark registries and the internet, including Amazon itself, because unregistered use can also block you. A federal search alone is not enough: the USPTO says its database “only contains federally registered and applied-for trademarks.”
Sources: the USPTO Trademark Registration Toolkit, its pages on federal trademark searching, likelihood of confusion, comprehensive clearance search, coordinated classes, and the getting started and field tag handouts (all data checked 2026-10-15). This guide explains how to search; it does not judge whether any particular name is available. Once your search is done, the filing itself is covered in our USPTO trademark application guide.
What a Trademark Clearance Search Is Looking For
The USPTO toolkit puts the goal plainly: before you file, run a comprehensive clearance search “to determine if your trademark conflicts with the rights of another owner. If it does, consider creating a new trademark.” For an Amazon seller, the cheapest moment to change a name is before you print packaging and build listings around it.
The conflict the search looks for is likelihood of confusion, which the USPTO calls “the most common reason for refusing registration.” It has two halves, and a mark needs both to cause a problem:
| Question | What counts | USPTO example |
|---|---|---|
| Are the marks confusingly similar? | Similar in sound, appearance, or meaning, or a similar commercial impression | TEE MARQEE and T.MARKEY against a t-shirt brand pronounced the same way |
| Are the goods or services related? | Identical, similar or competitive; used together; same buyers; advertised together; same maker or dealer | T-shirts and hats, t-shirts and handbags, t-shirts and clothing store services |
Two points in that table catch most first-time sellers. “Trademarks don’t have to be identical to be confusingly similar,” so an exact-match search that comes back empty proves little. And related goods do not have to match yours: the USPTO’s federal searching page says goods “don’t have to be in the same international class to be related.” The reverse also holds. The USPTO notes that identical marks with different owners can coexist when the goods are unrelated, citing Dove soap and Dove ice cream bars.
The USPTO also gives a practical test for relatedness: what else would a customer expect you to sell, what products sit in the same store aisle as yours, and what is used or advertised with it. On Amazon, a quick version is to look at the products Amazon suggests buying alongside yours and the other products in your category.
Step 1: Search the USPTO Trademark Database
The USPTO’s search system lives at tmsearch.uspto.gov and is free. The USPTO suggests signing in with a USPTO.gov account to avoid errors during heavy traffic. Per the getting started handout, it offers two ways to search: drop-down searches (such as Wordmark, Goods and services, Owner, and Design code) and a Field tag and Search builder option for complex, multiple-term queries. You cannot combine the two in one search. A Basic mode covers the basics; Expert mode, switched on with the “Expert” button near the search bar, lets you combine search lines and filter by coordinated class.
One trap in the drop-downs: a Wordmark search with several words does not search them as a phrase. The handout explains that each word is treated as its own search term, so results include records matching just one of the words. For multi-word brand names, use field tags.
Build the search in widening rings
The USPTO’s federal searching page lays out a word-mark strategy that moves from exact to loose. The table below applies it to KIVORA, a made-up brand name for silicone kitchen utensils used only for illustration (we have not searched it).
| Ring | What it finds | Example query |
|---|---|---|
| 1. Knock-out search | Marks containing your exact word | CM:kivora |
| 2. Expand | Your word with anything before or after it | CM:/.*kivora.*/ |
| 3. Alternative spellings | Marks a customer would pronounce the same way | CM:/.*keevora.*/, CM:/.*kivorra.*/ |
| 4. Combined terms | Strong words of a multi-word name, separately and together | CM:"north nest" AND LD:true (a second made-up name) |
The combined mark field, tag CM:, covers the word mark plus pseudo mark, translation, and transliteration fields. Field tags go in capitals followed by a colon, search terms in lowercase, and the handout recommends straight quotes rather than curly ones. In field tags, ? stands for one character and * for any run of characters, and AND, OR, and AND NOT join statements. The USPTO calls the exact-word pass a “knock-out search,” but don’t stop there, in its words: most federal searches mean “searching multiple times using different combinations of terms.”
Two habits from the same page save time. Start narrow, because one exact registered match for related goods ends the question early. Then, as you broaden, add AND NOT 1 (the number of your earlier query in Expert mode search history) to skip results you have already reviewed.
Search the logo separately
If your brand has a logo, words-only searching misses it. The system has no reverse image search; instead you look up six-digit codes in the Design Search Code Manual and search them with the DC: tag, for example DC:050101 for evergreen trees, or DC:0501?? for tree and bush designs of any shape.
Step 2: Check Related Goods Without Narrowing Too Far
A broad search can return thousands of records, and the natural reflex is to filter down to your own international class. The USPTO’s advice is the opposite: “Only narrow by goods or services if absolutely necessary.” Filter by international class and “you won’t see any trademarks used on goods and services that are related to yours but in a different class.”
The safer filter is the coordinated class. The USPTO groups classes whose goods are closely related. Its own example: International Class 25 (clothing) coordinates with Class 14 (jewelry), Class 18 (leather goods, including handbags), and Class 35 (advertising and business services, including retail store services). In a field tag search the tag is CC:, as in CM:kivora AND LD:true AND CC:021; in a drop-down search you need Expert mode to use the coordinated class filter.
Class 35 deserves a look for nearly every Amazon brand, because online retail store services sit there. The USPTO toolkit’s own t-shirt example lists a conflicting mark for “online retail store services featuring clothing.”
For each hit, click through to the Trademark Status and Document Retrieval (TSDR) record to read the full goods list, owner, and status before you decide whether it overlaps with what you sell.
Step 3: Search Beyond the Federal Database
The examining attorney who reviews your application will search too, but the USPTO’s “why search” page says “they will only determine whether there are conflicting trademarks in our federal database.” The toolkit is direct about what that leaves: “A trademark doesn’t need to be federally registered to cause likelihood of confusion and future legal troubles. It’s your responsibility to search for conflicting trademarks.”
Unregistered marks matter because of common-law rights. The USPTO explains that these rest only on use in US commerce with specific goods or services, and earlier common-law use “may affect the rights provided by your federal registration.” Our TM vs ® guide explains what those unregistered rights cover.
The USPTO’s comprehensive clearance page lists these sources:
| Source | What it covers |
|---|---|
| USPTO trademark search | Federally registered and pending marks |
| Trademark Official Gazette | Weekly publication of Principal Register marks that received preliminary approval |
| State trademark links | Registries for the 50 states, Washington, D.C., and Puerto Rico |
| ICANN registrant page | Domain name registries |
| Madrid Monitor | International registrations through the Madrid System |
| WIPO Global Brand Database | Marks from national and international sources |
| EUIPO and TMview | EU office marks and partner offices |
| Search engines | Unregistered use on related goods |
The USPTO’s floor: “At a minimum, be sure to check our database and the TMOG for federal applications and registrations, and also search the internet for common-law use.”
For an Amazon seller, the internet search has an obvious extra stop. Search your brand name, its alternative spellings, and your product type in the Amazon store itself, plus Walmart, Etsy, and Shopify storefronts that show up in a web search. A small seller with no registration but years of sales under a similar name is exactly the conflict a federal search cannot show. If you plan to sell in Amazon’s European or other stores later, the Madrid Monitor, Global Brand Database, and TMview rows matter now, not after launch.
Reading Your Results: Live, Dead, and When to Rename
Status changes how much a hit matters. The USPTO writes that “Only live trademark applications and registrations can prevent your trademark from being registered,” and you can untick the “dead” status checkbox to filter them out. It adds a warning: dead records can still present legal problems if the mark is still used in commerce, and in certain cases an owner can rely on common-law rights even against someone holding a federal registration.
A pending application filed before yours also counts. If it registers, the examining attorney may refuse yours on that basis.
Keep expectations in proportion. The USPTO says searching “can’t give you a clear-cut answer about whether your trademark can be registered,” that it does its own search during examination and “might come to a different conclusion than you,” and that “we don’t refund filing fees” if registration fails. That is why many sellers treat a close call as a reason to pick a different name. The USPTO also points to private trademark attorneys or screening services for a deeper search with interpretation; Amazon’s program for vetted law firms is covered in our IP Accelerator guide.
Clearance Search Checklist for an Amazon Brand Name
- Write down every product you plan to sell under the name, including likely line extensions.
- Run a knock-out search with
CM:, then expanded, misspelled, and sound-alike variants. - Search each strong word of a multi-word name on its own and combined.
- Search your logo’s design codes with
DC:if you have a logo. - Filter by coordinated class, not international class, and always check Class 35.
- Open the TSDR record for every live hit on related goods.
- Check the Trademark Official Gazette for recently published marks.
- Search the state registries for the states where you sell or are based.
- Search Amazon, other marketplaces, search engines, and domain registries for unregistered use.
- Repeat the international databases for any non-US Amazon store you plan to enter.
- Save your queries and results in case you need to explain your choice later.
Common Mistakes Sellers Make When Checking a Brand Name
- Searching only the exact spelling. The USPTO’s own refusal examples are sound-alikes and look-alikes.
- Filtering to one international class. Related goods often sit in other classes.
- Stopping at the USPTO database. State registrations and unregistered use are outside it.
- Treating an empty Amazon search as clearance. It shows nothing about registered marks off Amazon.
- Typing a multi-word name into the Wordmark drop-down. It searches words separately, not as a phrase.
- Ignoring the logo. Design marks need design-code searches.
Frequently Asked Questions
How do I check if a brand name is taken before selling on Amazon?
Search the USPTO trademark database for identical and similar marks on related goods, then search state registries, search engines, and Amazon itself for unregistered use. No single source answers the question, which is why the USPTO calls it a comprehensive clearance search.
Is the USPTO trademark search free?
Yes. The search system at tmsearch.uspto.gov is free to use, and signing in with a USPTO.gov account is recommended to avoid errors under heavy traffic.
Does a different spelling make my brand name safe?
Not by itself. The USPTO counts marks that sound alike, look alike, or share a meaning as confusingly similar, so alternative spellings are one of the searches you run, not a way around a conflict.
Do I need a clearance search if I only want Amazon Brand Registry?
Yes, in practice. Brand Registry asks for a registered trademark or a pending application, as our Brand Registry guide explains, and that application goes through a USPTO examination that searches the federal database for conflicts. The state and common-law checks are yours alone.
Conclusion
A trademark clearance search before naming an Amazon brand is two searches, not one: the USPTO database in widening rings across related goods, then state registries and the open web, Amazon included, for unregistered use. Do both before you buy packaging. If a close match turns up on related goods, renaming now is cheaper than a refusal or an opposition after launch. Then move on to the USPTO application steps, and once you are enrolled in Brand Registry, the listing hijacking playbook covers how to protect the name you cleared.
