Published notices

We publish weekly lists of patents for which maintenance fees may now be paid and of patents expired for failure to pay maintenance fees in the Official Gazette. Choose the year and week of interest and select the "Notice of Maintenance Fees Payable" or the "Notice of Expiration of Patents Due to Failure to Pay Maintenance Fee" links.

Go to the Official Gazette

If a maintenance fee has not been paid in a timely manner and the owner of the patent wants to get the patent rights reinstated, a petition and proper fees are required.

Who can submit the petition?

A petition to reinstate an expired patent must be submitted by a recognized party. Be sure to review guidelines to determine who qualifies as a recognized party.

What are the petition requirements?

Any petition to accept an unintentionally delayed payment of a maintenance fee must include: 

1. the required maintenance fee set forth in § 1.20(e) through (g)
2. the petition fee as set forth in § 1.17(m)
3. a statement that the delay in payment of the maintenance fee was unintentional
4. be signed in compliance with § 1.33(b).

We will require additional information when the petition is filed more than two years after the date the patent expired for nonpayment. The additional information is required to ensure that we are provided with sufficient facts and circumstances to support a conclusion that the entire delay was “unintentional.”

How much to pay?

View the current maintenance fee and petition fee amounts on the USPTO Fee Schedule . The surcharge for late payment within 6 months set forth in § 1.20(h) is not required.

When will my petition be processed?

Web-based ePetitions filed via Patent Center are automatically processed and granted immediately upon submission if the petition meets all of the requirements. Petitioners will know instantly whether all requirements have been met.

Petitions filed in paper (mailed, faxed, or submitted as a PDF attachment in Patent Center) are subject to significant processing delays and the filing does not guarantee a granted petition.

Where to submit my petition?

Please use one of the following two options:

1. Submit in Patent Center – If the date of expiration is less than two years, file a petition using the Web-based ePetition in Patent Center (currently registered independent inventors and practitioners only). Refer to the ePetition resource page for additional information.

Go to Patent Center

2. Submit by mail or fax – If the date of expiration is more than two years, file a petition by submitting the completed form SB/66 and Credit Card Payment Form (if paying with a credit or debit card). Checks or money orders should be made payable to the “Director of the USPTO”.

Contact the Office of Petitions at 571-272-3282 for assistance on filing a petition to accept unintentionally delayed payment of the maintenance fee.

What is a deficiency payment under 37 CFR 1.28(c) or 1.29(k)?

If small or micro entity was established in good faith, and you paid a maintenance fee as a small or micro entity in good faith but later discover that such status was established in error or that through error we were not notified of a loss of entitlement to such status, we will excuse the error if a deficiency payment and other requirements are submitted in compliance with 37 CFR 1.28(c) or 1.29(k). This is known as a “1.28(c) petition” or “1.29(k) petition.”

What to include with a deficiency payment petition?

A separate submission is required for each patent paid in error. You must submit an itemization of the deficiency payment as follows:

1. Each particular type of fee that was previously paid in error (e.g., maintenance fee due at 3.5 years, surcharge - 3.5 year)
2. The fee amounts previously paid, and the date on which it was paid
3. The deficiency owed amount (for each fee erroneously paid)
4. The total deficiency payment owed, which is the sum of the individual deficiency owed amounts.

How do I calculate the amount owed?

Use the difference between the current fee amount (based on the USPTO Fee Schedule) and the amount previously paid in error.

If the original small or micro entity fee amount was paid with no surcharge during the window period, no surcharge is required. If the original small or micro entity fee amount was paid with a surcharge during the grace period, an additional surcharge is required.

Who can submit a deficiency payment petition?

The deficiency payment petition must be signed by a recognized party. Be sure to review guidelines to determine who qualifies as a recognized party.

When will my deficiency payment petition be processed?

The payment is processed upon receipt. However, the Office of Petitions must make a formal decision on the acceptance of the deficiency payment petition. The entity status change and additional payment will not be reflected on the maintenance fee statement until after the petition has been granted. This may take considerable time as they are manually reviewed in the order received.

Where to submit a deficiency payment petition?

Please use one of the following two options:

1. Submit in Patent Center (deposit account payment only) – Must be a registered Patent Center user.

Go to Patent Center

2. Submit by mail or fax – Complete the 1.28(c) or 1.29(k) petition requirements and Credit Card Payment Form (if paying with a credit or debit card). Checks or money orders should be made payable to the “Director of the USPTO.”

What happens if I don’t pay a maintenance fee?

If maintenance fees and any applicable surcharges are not paid the patent protection lapses and the rights provided by a patent are no longer enforceable.

Reminder and expiration notices

It is the responsibility of the patentee to ensure maintenance fees and any applicable surcharges are paid timely to prevent expiration of the patent. If the maintenance fee is not paid within the first six months in the year in which it can be paid, a Maintenance Fee Reminder notice is sent to the fee address or correspondence address on record.

If the maintenance fee and any applicable surcharge are not paid by the end of the 4th, 8th, or 12th years after the date of issue, the patent rights lapse and a Notice of Patent Expiration is sent to the fee address or correspondence address on record.

Failure to receive the notices will not shift the burden of monitoring the time for paying a maintenance fee from the patentee to the USPTO. If a fee address has not been established, the notices are sent to the correspondence address.

SCAM ALERT: there are numerous companies unaffiliated with the USPTO that send solicitations to patent owners concerning maintenance requirements. Scammers also attempt to fool patent owners into providing personal or payment information by falsely claiming to be an employee with the USPTO. See the warning about non-USPTO solicitations and the warning about spoofed calls that impersonate the USPTO for more information.

Reissue patent families

Effective January 16, 2018, there are changes for maintaining in force individual patents in reissue patent families. See the Official Gazette notice and the frequently asked questions (FAQs) for more information about the change.

Expiration dates

Generally, utility patents expire after 20 years from the application filing date subject to the payment of appropriate maintenance fees. The USPTO does not calculate the expiration dates for patents. In response to patent owner and public inquiry, the USPTO provides a downloadable patent term calculator as a resource to help the public estimate the expiration date of a patent. See the Patent Term Calculator page for more information.

Patent Maintenance Fees Storefront

The Patent Maintenance Fees Storefront is the USPTO’s online search and payment tool for patent maintenance fees. Any user may access this site as a guest to view or pay fees, but signed in uspto.gov registered users will have access to additional features. Check out the Video Introduction to the Patent Maintenance Fees Storefront to learn more.
