What information is required for a maintenance fee payment to comply with 37 CFR 1.366(c)?

To comply with 37 CFR 1.366(c), a maintenance fee payment must include specific identifying information. MPEP 2532 states:

“If the duplicate payment does comply with 37 CFR 1.366(c) by containing both the patent number and the corroborating application number, the Office will verify that the first payment was properly processed.“

This indicates that for a maintenance fee payment to be compliant, it must include:

• The patent number
• The corroborating application number

Both pieces of information are essential for the USPTO to properly process and apply the payment to the correct patent.
