Certification Not Required for Each Fee Payment Once Established
Note:
An applicant does not need to provide a micro entity status certification with each fee payment after it has been established, but must still meet the requirements at the time of payment.

An applicant is not required to provide a certification of micro entity status with each fee payment once micro entity status has been established by filing a certification in an application. While an applicant is not required to provide such a certification with each fee payment, the applicant must still be entitled to micro entity status to pay a fee in the micro entity amount at the time of all payments of fees in the micro entity amount. Thus it must be determined whether the requirements for micro entity status exist at the time each fee payment is made. If any requirement for micro entity status is no longer met, then the applicant must notify the Office of loss of micro entity status and pay the required fee in the small entity or undiscounted amount, as appropriate.

Applicant Must Reconfirm Micro Entity Status Each Year
Note:
The applicant must annually verify that both the applicant and inventors/joint inventors still meet the gross income and assignment conditions to maintain micro entity status.

For micro entity status on the gross income basis under 37 CFR 1.29(a), the applicant must determine that the applicant and each inventor or joint inventor still meet the applicable conditions of 37 CFR 1.29(a) to claim micro entity status. For example, the applicant must determine that neither the applicant nor inventor nor joint inventor has had a change in gross income that exceeds the “maximum qualifying gross income” as reported on the USPTO website (a new determination must be made each year because gross income may change from year to year, and micro entity status is based upon gross income in the calendar year preceding the calendar year in which the applicable fee is being paid). In addition, the applicant must determine that neither the applicant nor inventor nor joint inventor has made, or is obligated by contract or law to make, an assignment, grant, or conveyance to an entity exceeding the “maximum qualifying gross income,” and that no new inventor or joint inventor has been named in the application who does not meet the conditions specified in 37 CFR 1.29(a).
