How to Pay and Track Patent Maintenance Fees
Understanding Patent Maintenance Fees
A patent maintenance fee payment keeps an issued patent in force after grant. The USPTO requires these fees for many utility patents. Design and plant patents follow different rules.
For a utility patent, payments are due at three points. These points fall about 3.5, 7.5, and 11.5 years after the patent grant date. The due date comes from the issue date, not the filing date.
The USPTO sets a fee for each payment window. The amount also depends on the patent owner’s entity size. Small and micro entities may pay less than large entities. Check the current fee table before sending money.
Use the USPTO maintenance fee guidance for current rules and fee amounts. This official page also explains which patents need these payments.
- First payment window: 3.5 to 4 years after issue
- Second payment window: 7.5 to 8 years after issue
- Third payment window: 11.5 to 12 years after issue
- Six-month grace period after each window closes
The exact amount matters. A wrong fee can delay processing or leave the payment short. Confirm the patent number, entity status, and fee tier before you pay.

How to Pay a Patent Maintenance Fee
Most owners use the USPTO online payment system. Start with the patent number and the owner’s entity status. The system then shows the fee due for that patent.
Review every field before you submit the payment. Save the receipt, confirmation number, and payment date. These records help if the USPTO later questions the payment.
You can also mail a check to the USPTO. Use the current mailing address and payment form listed in the USPTO instructions. Allow enough time for delivery and processing.
A mailed payment creates more timing risk. The USPTO must receive the payment within the allowed period. A postmark alone may not protect you in every case.
Online payment steps
- Find the patent number and grant date.
- Open the USPTO maintenance fee payment page.
- Confirm the owner’s entity status.
- Select the correct payment window.
- Pay the fee and save the receipt.
Patent maintenance fee payment services can help manage many patents. Still, the owner remains responsible for each deadline. Ask a service for clear proof of payment and a backup record.

How to Check Maintenance Fee Payment Status
You can check maintenance fee status through the USPTO Patent Maintenance Fees Storefront. Search by patent number to see due dates and payment records. The result can show whether a fee was paid, due, or late.
Patent owners may also use the USPTO’s patent file systems. The older PAIR system gave users access to patent records. The USPTO now directs many users to Patent Center for current file access.
Status data may not update at once after payment. Keep your receipt until the record shows the payment. Contact the USPTO if the record stays wrong after a fair processing period.
Check the record before buying, selling, or licensing patent rights. A missed fee can change the value of the patent. It can also affect a deal’s closing date.
| What to check | Why it matters |
|---|---|
| Patent number | Prevents payment on the wrong patent |
| Grant date | Sets each maintenance fee deadline |
| Payment date | Shows whether the payment was timely |
| Entity status | Sets the fee amount |
| Receipt number | Supports proof of payment |
Run a status check after each payment. A simple check can catch a rejected card, wrong patent number, or short payment.

What Happens When a Payment Is Late?
The USPTO gives a six-month grace period after each regular payment window. You can often pay during this period with a surcharge. The surcharge raises the total cost.
Do not treat the grace period as a normal deadline. Late payment can still cause record gaps and added work. Pay as soon as you find the missed fee.
If the grace period ends without payment, the patent can expire. The USPTO records the lapse under its patent records. The owner may lose the right to stop others from using the invention.
Some owners can seek revival after an unintentional lapse. A petition, statement, and fee may be needed. Relief is not automatic, so speak with a patent lawyer before filing.
A missed payment can end valuable patent rights. Treat every deadline as a hard business date.
Revival may also fail when the facts do not support the required showing. The owner should gather notices, docket records, and payment history. Quick action gives the best chance of finding a workable path.
Tips for Managing Patent Maintenance Fees
Good docket control lowers the risk of a missed payment. Record the issue date for every utility patent. Then set reminders before each fee window opens.
Use at least two reminders for each deadline. Set one reminder several months ahead. Set another reminder before the grace period ends.
Review the portfolio each quarter. Remove patents that no longer support the business. Keep funds ready for patents that still matter.
- Store the patent number and grant date in one secure record.
- Review entity status before each payment.
- Check the USPTO record after payment.
- Keep receipts and payment confirmations.
- Use a trusted service for large patent portfolios.
- Ask counsel about a missed fee without delay.
A service can track dates, send alerts, and collect payment data. Compare its process with your own records. You should know who pays, who checks the result, and who handles errors.
Owners with patents in several countries need a wider plan. Each country sets its own dates, fees, and late rules. Do not assume a USPTO deadline matches a foreign patent deadline.
Patent fees form one part of intellectual property management. A clear schedule protects rights and helps control legal costs. It also makes patent ownership easier to review during a sale or investment round.
