How to Search State Trademark Databases
- Enter your mark. Use the exact word, name, or slogan you plan to use.
- Pick each state where you do business. The tool copies your mark and opens that state's official search.
- Search variations. Try plurals, alternate spellings, sound-alikes, and the dominant word on its own.
- Search the USPTO. Federal registrations and pending applications carry nationwide priority.
- Get an attorney review. Hits need legal analysis: related goods, commercial impression, and common-law users.
State vs. Federal Trademark Search
| State search | USPTO search | |
|---|---|---|
| What it covers | Marks registered in one state | Federal registrations and pending applications |
| Geographic reach | That state only | Nationwide |
| One database? | No — 50 separate systems | Yes |
| Catches common-law users? | No | No |
| Enough on its own? | No | No — pair with state and common-law search |
A full clearance search covers all three: federal, state, and common-law (business names, websites, marketplaces, social media).
Searching Minnesota State Trademarks
Minnesota trademarks and service marks are registered with the Minnesota Secretary of State under Minnesota Statutes Chapter 333. They show up in the state's Business Filings Online search, alongside LLCs, corporations, and assumed names — so filter your results carefully.
State fees per the Minnesota Secretary of State as of September 2026; attorney fees are separate. Confirm current fees before filing.
A Minnesota registration is inexpensive, but it only reaches Minnesota. If you sell online or across state lines, our Minnesota Trademark Attorneys usually recommend a federal USPTO filing instead of, or in addition to, a state registration.
Why Work With Minnesota Trademark Attorneys?
A search tool shows you records. It doesn't tell you whether "North Loop Coffee" conflicts with "Northloop Roasters" in a neighboring class. That call takes legal judgment.
- Flat-fee pricing — know your cost before we start.
- Federal, state, and common-law coverage in one clearance review.

- Filing handled start to finish with the USPTO or the Minnesota Secretary of State.
Found a possible conflict?

State Trademark Search FAQs
What is a state trademark search?
A state trademark search checks a state's own registry, usually kept by the Secretary of State, for marks registered only in that state. State registries are separate from the federal USPTO database, so a clear state search does not mean a mark is available nationally.
Can I search all 50 state trademark databases at once?
No. There is no official combined database of state trademark registrations. Each state runs its own system, and several states offer no online search at all. This tool puts every state's official database or contact point on one page so you can work through them quickly. Commercial search reports compile state records for you.
Is a state trademark search enough before I file?
No. A proper clearance search covers the USPTO federal register, state registries, and unregistered common-law uses such as business names, websites, and social media. Most conflicts that sink an application come from federal filings or common-law users, not state registrations.
How do I search Minnesota state trademarks?
Use the Minnesota Secretary of State's Business Filings Online search at mblsportal.sos.mn.gov. The same search covers business entities, assumed names, and trademarks or service marks registered in Minnesota.
How much does a Minnesota state trademark registration cost?
The Minnesota Secretary of State lists a $50 filing fee by mail and $70 for expedited in-person or online filings. A Minnesota registration lasts 10 years and can be renewed during the 6 months before it expires. The mark must already be in use in Minnesota before you apply. Attorney fees are separate.
Should I register my trademark with the state or the USPTO?
If you sell across state lines or online, a federal USPTO registration is usually the better investment because it provides nationwide rights. A state registration can make sense for a purely local business. Our Minnesota Trademark Attorneys can help you decide based on how and where you use the mark.
Why don't some states show an online trademark search?
Some states, including New York, do not offer a public online trademark search. Others fold trademarks into a general business-entity search or charge per record. For those states, contact the agency directly or order a professional search report.
