MPEP 2500 – Maintenance Fees (4)
If you miss both the maintenance fee payment and the 6-month grace period, your patent will expire. However, the USPTO may accept late payments under certain conditions. According to MPEP 2501:
“The Director may accept the payment of any maintenance fee required by subsection (b) after the 6-month grace period if the delay is shown to the satisfaction of the Director to have been unintentional.”
To reinstate the patent, you must file a petition showing the delay was unintentional and pay the maintenance fee along with any required surcharges. If accepted, “the patent shall be considered as not having expired at the end of the grace period.”

A terminal disclaimer can affect the term of a patent, but it does not change the maintenance fee payment requirements. According to MPEP 2520:
“The term of a patent might be shortened, e.g., by a terminal disclaimer. If a patent will expire part way between the due dates set in 35 U.S.C. 41(b), or between the latest due date and the term set in 35 U.S.C. 154, it is still required that the entire maintenance fee amount for the due date be paid.”
This means that even if a terminal disclaimer shortens the patent term, you are still obligated to pay the full maintenance fee for each due date that occurs before the patent expires. The USPTO does not prorate or reduce maintenance fees based on a shortened patent term resulting from a terminal disclaimer.

According to MPEP 2515, anyone can pay maintenance fees for a patent. Specifically, the section states:
“The patentee may pay maintenance fees and any necessary surcharges or any person or organization may pay maintenance fees and any necessary surcharges on behalf of the patentee.“
This means that the patent owner, a legal representative, or even a third party can submit the payment. No special authorization is required for someone other than the patentee to pay the fees.
To learn more:
Are maintenance fees required for all types of patents?
No, maintenance fees are not required for all types of patents. The MPEP 2504 provides clear guidance on which patents are subject to maintenance fees:
“Maintenance fees are required to be paid on all patents based on applications filed on or after December 12, 1980, except for plant patents based on applications filed before June 8, 1995. This includes reissue patents as well as original patents.“
Here’s a breakdown of maintenance fee requirements by patent type:
- Utility patents: Subject to maintenance fees
- Design patents: Not subject to maintenance fees
- Plant patents (filed before June 8, 1995): Not subject to maintenance fees
- Plant patents (filed on or after June 8, 1995): Subject to maintenance fees
- Reissue patents: Subject to maintenance fees if the original patent was subject to them
It’s crucial for patent holders to understand these distinctions to properly maintain their patent rights and avoid unintentional expiration due to non-payment of required fees.
