USPTO Trademark Search Guide
Learn how to use the USPTO’s current Trademark Search system for exact wording, expanded variants, owner and field searches, and record verification.
General educational information only. Not legal advice.
The USPTO now uses its cloud-based Trademark Search system for public federal searching. Older guides that direct users to TESS are outdated. For the full research workflow beyond this interface, see how to do a trademark search.
The system covers federal applications and registrations. It does not, by itself, cover every state record or unregistered common-law use.
Before opening the database
Prepare:
- the exact proposed wording;
- spelling, spacing, and phonetic variations;
- the goods and services;
- related product or service terms;
- possible translations; and
- owner names you may need to investigate.
Searching is more effective when the query plan exists before the results begin to influence it.
Start with an exact-word search
The USPTO’s federal-search guidance starts with exact wording in the combined mark field. In field-tag mode, CM:uspto searches that wording and CM:"united states patent and trademark office" illustrates a multiword phrase. Use straight quotation marks in the interface. These are USPTO syntax examples, not a Seneka search result.
An exact search can reveal:
- identical live records;
- pending applications;
- owner patterns;
- relevant goods and services; and
- dead records that merit follow-up.
This is a knock-out step, not the end of the search.
Expand the wording
Search individual distinctive terms and likely variations. Consider:
- words together and apart;
- plural and singular forms;
- common vowel or consonant substitutions;
- phonetic equivalents;
- reordered terms;
- abbreviations;
- translations; and
- dominant wording without highly descriptive elements.
Broad searches may return noise. Record each query, then use fields or filters when necessary to make the result set reviewable. USPTO cautions that narrowing prematurely to one international class can hide related offerings in other classes.
Use the current search fields
The official Trademark Search help lists field tags and formatting rules. Choose the Field tag and Search builder option to construct a query without memorizing the syntax, or use a tag directly. Field tags and logical operators must be uppercase.
| Goal | Illustrative query | What it does |
|---|---|---|
| Combined mark wording | CM:USPTO |
Searches the combined mark field |
| Exact multiword phrase | CM:"happy birthday" |
Searches that phrase; use straight quotes |
| Live records containing a term | CM:dog AND LD:true |
Narrows to live records; review relevant dead records separately |
| Owner | ON:"John Smith" |
Searches an owner name |
| Serial number | SN:90866054 |
Opens a search by serial number |
| Goods and services | GS:"yoga pants" |
Searches the goods-and-services field |
| Design code | DC:030111 |
Searches a coded design element |
These examples demonstrate syntax from USPTO help; they are not search findings or a recommended clearance query for a particular business. Check the current help page if labels or syntax change. Signing into a USPTO.gov account may improve access during heavy traffic and enables some additional result features; public searching does not require an account.
Read the result, not just the title
For each potentially relevant record, review:
| Field | Review question |
|---|---|
| Status | Is the application or registration live, pending, abandoned, or cancelled? |
| Mark | What wording and design are actually claimed? |
| Goods/services | How close are they to the proposed offering? |
| Owner | Are there related records under the same owner? |
| Dates | What timing information is available? |
| Basis | What filing basis and use information appear? |
Open the result details, then review its Trademark Status and Document Retrieval (TSDR) status and documents for material records. Save the serial or registration number and the date checked. A result tile or count alone does not establish a conflict.
Design searches
If a logo contains a meaningful design, use the USPTO Design Search Code Manual and applicable search fields. Design searching is not the same as uploading an image and receiving a legal answer.
Word elements in a logo may still be important. Consider separate word and design searches rather than assuming one query covers both.
Status cautions
Live does not mean the record necessarily blocks your mark. Dead does not mean the name is free to use.
A dead record may correspond to a business that continues using the mark. A live record may cover unrelated goods or create a different commercial impression. Status is one input.
Save a reproducible search record
For each search line, keep the date, exact query, filters, result count, and serial numbers selected for review. For each material record, note its current TSDR status, actual goods or services, the similarity you observed, and what still needs investigation. A blank result under one query means only that the query returned nothing under those filters.
For important decisions, revisit material records immediately before filing or launch. Federal statuses can change. For a reusable research log and the broader non-federal steps, use the proper trademark search guide.
Where Seneka Labs fits
Seneka Labs organizes preliminary similarity, status, and goods-and-services signals from retrieved U.S. federal records across classes, using a dated USPTO data snapshot. Check the snapshot and coverage details in its report and verify significant records in current USPTO sources. It does not search every marketplace use or issue legal clearance; the public methodology explains the scope.
Frequently asked questions
What replaced TESS?
The USPTO transitioned to its cloud-based Trademark Search system. Current search guidance and the search interface are available from the USPTO trademark-search pages.
Do I need a USPTO account to search?
Public searching is available, while the USPTO recommends logging in for a better experience and added features.
Does the database include unregistered trademarks?
No. Federal search results do not capture every common-law use, state registration, or business name.
Can I search by trademark class?
Yes, but class filtering should not replace reviewing related goods and services across possible class boundaries.
Is a zero-result search proof of availability?
No. Query design, variations, unregistered use, record timing, and legal analysis still matter.
