A Minnesota-focused guide from Twin Cities Trademarks | Trademark Lawyers | St. Paul, MN | Minneapolis, MN and the Twin Cities
Updated October 2026 | Reviewed for Minnesota businesses, entrepreneurs, and startups
Direct Answer
Trademark scams are becoming more aggressive, especially in Minnesota. Fraudsters impersonate the USPTO, scrape public TSDR data, and send official‑looking emails or letters demanding payment, “verification calls,” or “endorsement fees.” Any message from non‑@uspto.gov domains — including Teas@tsdrlawoffice.com, www.pto-us.com, and similar look‑alike sites — is fraudulent. The USPTO never requires phone calls, never asks for payment by email, and never uses third‑party websites for trademark filings. Minnesota businesses should delete these messages immediately and contact a licensed trademark attorney to confirm real deadlines.

1. Why Trademark Scams Are Increasing
Trademark filings have surged nationwide, especially among small businesses, Amazon sellers, and new LLC owners. Scammers know:
- TSDR data is public
- Minnesota LLC filings are public
- Entrepreneurs often file trademarks without legal counsel
- Many applicants don’t know how the USPTO communicates
This creates a perfect environment for impersonation scams.
2. The Most Common Scam Types
A. Fake USPTO Emails
These messages impersonate examining attorneys and demand immediate action. Example: Teas@tsdrlawoffice.com (fraudulent)
B. Fake “Trademark Offices”
Scam websites pretend to be official filing portals. Example: www.pto-us.com — a known scam site designed to mimic USPTO branding.
C. Fake Renewal Notices
Letters demanding payment for “renewal,” “maintenance,” or “publication.”
D. Fake Monitoring Services
Scammers offer “mandatory monitoring” or “brand protection” for hundreds of dollars.
E. Fake Secretary of State Notices
These claim your Minnesota LLC must “verify” or “endorse” your trademark — which is false.
3. Known Scam Domains
Below are active scam domains frequently reported by Minnesota business owners:
- Teas@tsdrlawoffice.com
- www.pto-us.com
- tsdr‑verification.com
- uspto‑filings.org
- trademark‑verification.net
- uspto‑renewal.com
- federal‑trademark‑office.org
These sites and emails are not affiliated with the USPTO.
4. How to Identify a Fake USPTO Message
A. Check the Email Domain
Real USPTO emails always end in @uspto.gov. Anything else is fraudulent.
B. Look for “Mandatory Calls”
USPTO does not conduct trademark examination by phone.
C. Watch for Payment Requests
USPTO fees are paid only through official TEAS forms.
D. Beware of Urgent Threats
Scammers often claim your trademark will be abandoned “today” or “within 24 hours.”
E. Check for Secretary of State References
Federal trademarks have nothing to do with Minnesota Secretary of State filings.
F. Look for Poor Grammar
Most scam messages contain formatting errors, typos, or awkward phrasing.
5. Minnesota‑Specific Risk Factors
Minnesota businesses are targeted more frequently because:
- The Twin Cities metro has dense brand overlap
- Minnesota LLC filings are easy to scrape
- Many local businesses operate across multiple suburbs
- Minnesota has a high number of Amazon sellers and e‑commerce brands
- New LLC owners often receive scam notices within 48 hours of filing
If you’re located in Minneapolis, St. Paul, Coon Rapids, Maple Grove, Bloomington, or surrounding suburbs, you are in a high‑risk zone.
6. What To Do If You Receive a Scam
- Do not respond.
- Do not call the number.
- Do not send product photos or payment.
- Forward the email to TMScams@uspto.gov.
- Contact Twin Cities Trademarks PLLC to confirm real deadlines.
- If you paid money, immediately contact your bank to dispute the charge.
