How to Check If Your Patent Maintenance Fees
Have Been Paid

The USPTO Patent Maintenance Fees Storefront is the official lookup tool. Enter the patent number and you can see the payment status for all three maintenance fees, including dates, entity status, and any surcharges paid.

How to look up a patent's fee status

A 90-second check that confirms whether the patent is in force.

1
Open the Patent Maintenance Fees Storefront
Go to fees.uspto.gov on the USPTO website. The Storefront is the official portal for looking up and paying maintenance fees. As of September 2024, viewing payment history requires a uspto.gov account.
2
Enter the patent number
Type the 7- or 8-digit US patent number (no commas, no leading zeros). The Storefront also accepts the application number if you do not have the patent number handy.
3
Review the fee history
The system shows each maintenance fee payment with its date, the entity status used (large/small/micro), the amount paid, and any surcharge. Unpaid fees show as "due" with the deadline date.
4
Download a receipt or fee history report
Save the report as a PDF for your records. If you just made a payment, the receipt is available immediately after the transaction completes.

Just confirmed your fee was paid? Set the reminder for the next window now, while the dates are in front of you.

What each status on the Storefront means

Patent Maintenance Fees Storefront — status meanings

  • Paid: the fee was received and processed; the patent is in force for that maintenance period
  • Due: the on-time window has opened but no payment has been received yet
  • Surcharge required: the on-time window has closed; you are inside the grace period and a surcharge applies
  • Expired: the grace period has ended without payment; the patent is no longer enforceable
  • Not yet payable: the on-time window for that fee has not yet opened

Other USPTO tools that show fee status

The Storefront is the primary tool, but two other systems also display maintenance fee information for the same patent.

🗂️

Patent Center

The USPTO's modern application portal. Look up by application number and view the file history, including maintenance fee payments. Replaced the legacy Public PAIR system in 2022.

PatentsView and bulk data

For research or portfolio analysis across many patents at once, the USPTO publishes maintenance fee event data in bulk downloads. Useful for IP analysts, not for individual fee checks.

After confirming a payment, set the next reminder immediately

The moment of confirmation is the most efficient time to schedule the next reminder. You have the patent number, the grant date, and the entity status all in front of you. Adding a reminder for the next maintenance window — 4 years away for the first or second fee — takes 30 seconds and saves you the work of looking everything up again later.

If you do not set the reminder now, you will rely on remembering to do it later. By the time the next window approaches, the only signal you will have is the USPTO's own Maintenance Fee Reminder, which arrives only after the grace period has begun. That is too late to be a safety net.

Verification handles today. The reminder handles four years from now.

Looking up the current status answers the immediate question. The bigger question is whether the next fee will be paid on time. See the patent maintenance fee reminder guide for the full setup, or read the complete fee schedule to know which window comes next.

Common questions about checking patent maintenance fee status

How do I check if my patent maintenance fees have been paid?

Visit the USPTO Patent Maintenance Fees Storefront and enter the patent number. The system shows the payment status for all three maintenance fees, including dates and entity status used for each payment. You can also view fee status through Patent Center using the application number.

Where is the USPTO Patent Maintenance Fees Storefront?

The Patent Maintenance Fees Storefront is the USPTO's online tool for looking up and paying maintenance fees, accessible from uspto.gov. As of September 2024, you must have a uspto.gov account to log in and view payment history or process new payments.

What does "expired" mean on the Patent Maintenance Fees Storefront?

It means the patent's maintenance fee deadline has passed and was not paid within the grace period, so the patent is no longer in force. To restore it, you would need to file a petition to revive under 37 CFR 1.378 — there is no automatic reinstatement from expired status.

Can I look up another company's patent maintenance fee status?

Yes. The Patent Maintenance Fees Storefront accepts any US patent number and returns its public payment status, regardless of who owns the patent. Anyone can verify whether a competitor's patent is currently in force.

How long does it take for a payment to show as paid?

Payments are typically reflected immediately upon successful submission. A receipt is available right after payment. If a payment was made by mail or check, processing can take several weeks. Always download and save the receipt as documentation.

What should I do after confirming a fee was paid?

Save the receipt to your patent file, then set a reminder for the next maintenance window — 4 years away for the first two fees. The moment of confirmation is the easiest time to schedule the next reminder, while the patent details and dates are already in front of you.

One Lookup Done — Now Set the Next Reminder

The hardest fee to remember is the one that's 4 years away. Set the reminder while the patent details are still in front of you.
