How Minnesota Trademark Applicants Can Spot Trademark Scams, Including pto-us.com

If you filed a federal trademark, your name and address are now in a public USPTO database, and scammers use that data. Here's how to tell a real USPTO notice from a fake one, and what to do if one lands in your inbox or mailbox.

Short answer

Real USPTO emails come only from addresses ending in @uspto.gov, and every real USPTO notice also appears in your file on the USPTO's TSDR system. Mailers from private companies such as pto-us.com, emails demanding a "mandatory verification appointment," and letters asking you to pay to "renew" or "prevent cancellation" are not from the USPTO. Don't call, click, or pay. Check TSDR, report the message to TMScams@uspto.gov, and have a trademark attorney confirm your real deadlines.

Why trademark scams are increasing

Small businesses, Amazon sellers, and new LLC owners are filing more trademarks than ever, and many file without an attorney. Every application creates a public record, and scammers build mailing lists from that record.

What scammers can see:

  • Your name, mailing address, and email from the USPTO's public TSDR records
  • Your mark, serial number, filing date, and class
  • Your business details from public Minnesota Secretary of State LLC filings

Why it works

Most first-time applicants don't know how the USPTO actually communicates. A letter that quotes your real serial number and filing date looks official, even when it comes from a private company.

The FTC has warned that these impersonators use realistic seals, the names of real USPTO employees, and spoofed caller ID to look official.

Key point: If a notice correctly lists your trademark details, that doesn't make it real. That information is public.

The most common trademark scam types

Most scams fall into one of five patterns. Some break the law, and others are legal but misleading solicitations that charge far more than the USPTO does for the same filing.

Email

Fake USPTO "examiner" emails

Messages that claim to be from an examining attorney and demand a phone call, a "verification appointment," or payment to keep your application alive.

Website

Look-alike "trademark office" sites

Commercial websites with names and branding that look like the USPTO. The real agency is only at uspto.gov.

Mail

Bogus renewal or cancellation notices

Letters warning of "pending cancellation" or a renewal deadline, with an invoice for hundreds or thousands of dollars.

Upsell

"Mandatory" monitoring or registry services

Offers to list your mark in a private "registry" or to provide "required" brand monitoring. No private registry or monitoring service is required by law.

State

Fake LLC "endorsement" notices

Notices claiming your Minnesota LLC must "verify" or "endorse" your federal trademark. Your Secretary of State filing and your USPTO registration are separate.

Reported look-alikes, including pto-us.com

None of the names below belongs to the USPTO. These examples come from public consumer reports and law firm alerts. New look-alikes appear constantly, so use the rules in the next section instead of relying on any list.

  • pto-us.comA private company, not the USPTO. Trademark owners report receiving mailers with a "Patent & Trademark Office" return name, "Open Immediately" warnings, and "pending trademark cancellation" language, along with an invoice.
  • @uspto-trademark-gov.live · @uspto-trademark.liveSender domains reported in fake "mandatory verification appointment" emails. Putting "uspto" in a domain name doesn't make it official.
  • @lawoffice119.comAnother sender domain reported in the same verification-appointment scam.

This list comes from third-party reports and is not complete. If a message isn't from @uspto.gov and doesn't appear in TSDR, treat it as unofficial.

The one rule that beats every list

The USPTO's own rule: Official communications, including office actions and any request for payment or information, are always uploaded to TSDR under the "Documents" tab. If it's not in TSDR, it's not an official communication.

Go to TSDR yourself by typing tsdr.uspto.gov into your browser, enter your serial number, and compare. Don't use any link in the suspicious message.

How to identify a fake USPTO message

CheckReal USPTORed flag
Sender / websiteEmails end in @uspto.gov; website is uspto.gov.com, .org, .net, .live, or "uspto" buried inside another domain
Where it appearsUploaded to your TSDR fileNot in TSDR

  1. Check the sender's domain.Look at the full address, not just the display name. Real USPTO email ends in @uspto.gov.
  2. Look it up in TSDR.Every real office action, notice, and payment request is posted there.
  3. Be wary of any payment request.USPTO fees are paid through the USPTO's own filing system, never by phone, invoice, or payment link.
  4. Ignore manufactured urgency.Real USPTO response periods are measured in months, not hours.
  5. Watch for sloppy details.Typos, odd formatting, and wrong agency names are common, but polished fakes exist, so don't rely on this check alone.

Minnesota-specific risk factors

Minnesota trademark owners get the same solicitations as everyone else. Several local factors increase the chance of a mistake:

  • Two public records, two mailing lists. A new Minnesota LLC and a new federal trademark each create a public record that solicitors can mine.
  • Lots of e-commerce sellers. Amazon, Etsy, and Shopify sellers across the metro often file on their own to qualify for brand programs, and they may not have an attorney to call.
  • Mixed-up state and federal filings. Many owners assume their LLC or a Minnesota state trademark is connected to their USPTO filing, which makes fake "endorsement" notices believable.
  • Notices often arrive soon after filing. Solicitations commonly start shortly after an application posts publicly, when new filers are most likely to expect mail.

Who we hear from most

We help business owners in Minneapolis, St. Paul, Coon Rapids, Maple Grove, Bloomington, Blaine, Eagan, and across greater Minnesota and Wisconsin. The pattern is usually the same: the owner filed without an attorney, received a letter that quoted their real serial number, and couldn't tell whether to pay it.

If you have an attorney of record, the USPTO sends official correspondence to your attorney. That gives you an easy test: if a "USPTO" notice reaches you directly and your attorney didn't send it, be suspicious.

What to do if you receive a trademark scam notice

  1. 1Don't respond

    Don't reply, click links, or call any number in the message.

  2. 2Don't pay or send anything

    That includes payment, personal information, ID, and product photos.

  3. 3Check TSDR yourself

    Type tsdr.uspto.gov into your browser and look up your serial number.

  4. 4Report it

    Send it to TMScams@uspto.gov and file a complaint at ReportFraud.ftc.gov.

  5. 5Already paid?

    Call your bank or card issuer immediately to dispute the charge.

  6. 6Confirm real deadlines

    Call Twin Cities Trademarks to review your file and calendar any real USPTO deadlines.

To reach the USPTO directly, call the Trademark Assistance Center at 1-800-786-9199, a number published on uspto.gov. Don't use a number from the suspicious message.

Frequently asked questions

Is pto-us.com a real USPTO website?

No. pto-us.com is a private commercial site, not the United States Patent and Trademark Office. The USPTO's only website is uspto.gov, a .gov domain. Trademark owners have publicly reported receiving mailers tied to pto-us.com that warn of pending trademark cancellation and request payment. Real USPTO notices appear in your file on TSDR.

How can I tell if an email from the USPTO is real?

Authentic USPTO emails end in @uspto.gov. Every official communication, including office actions and any request for payment or information, is also uploaded to your file in TSDR under the Documents tab. If it isn't in TSDR, it isn't an official USPTO communication.

Does the USPTO require a trademark verification appointment or phone call?

No. There is no mandatory verification appointment for trademark applications. Emails demanding one are a known impersonation scam. USPTO employees will never ask for personal or payment information over the phone, by email, or by text.

Can scammers access my trademark application?

Scammers read the same public USPTO records anyone can see, such as your name, address, mark, and serial number. Seeing that information in a letter doesn't mean your account was compromised, and it doesn't make the message legitimate.

Will my trademark be abandoned if I ignore a scam notice?

Ignoring a scam has no effect on your application or registration. Real deadlines come only from official USPTO actions recorded in TSDR, such as office actions, notices of allowance, and post-registration maintenance filings. Have a trademark attorney check your file so you don't miss a genuine deadline.

Where do I report a trademark scam?

Forward suspicious trademark emails or describe suspicious letters to TMScams@uspto.gov, and file a complaint with the FTC at ReportFraud.ftc.gov. If you paid, contact your bank or card issuer right away.

Does my Minnesota LLC filing affect my federal trademark?

No. Registering an LLC with the Minnesota Secretary of State is separate from a federal trademark registration with the USPTO. Any notice claiming your LLC must verify or endorse your federal trademark is false.

Not sure whether a trademark notice is real?

Send it to us before you call, click, or pay. Twin Cities Trademarks PLLC will check your USPTO file, tell you whether the notice is official, and confirm any real deadlines. If you're still preparing to file, we offer flat-fee searches and applications so you know what to expect from the USPTO from the start.
