What is the time limit for paying preliminary examination and handling fees?
The time limit for paying the preliminary examination fee and the handling fee is set forth in PCT Rule 57.3 and PCT Rule 58.1(b). According to the MPEP:
“The preliminary examination fee and handling fee are considered to have been received before the expiration of the time limit set in PCT Rule 57.3 if the fees were submitted prior to the sending of an invitation to pay the fees.” (See PCT Rule 58bis.1(c))
It’s important to note that if the fees are not paid within this time limit, the applicant may be subject to late payment fees or risk having their Demand considered as if it had not been submitted.
