Fees Not Required for Corrected Requests
Note:
If all applicable fees have been paid, they do not need to be resubmitted with a corrected request. The Office may grant a filing date even if the request is defective.

If all applicable fees have already been paid, these fees do not have to be resubmitted with the corrected request. Also, as discussed previously, even if the request (either the originally-filed request or the corrected request) is determined to be defective, the Office has the discretion under 37 CFR 1.610(d) to grant a filing date. See MPEP § 2812.01. For example, if the Office determines that a corrected request only contains one or more defects of minor character, the Office may, in its sole discretion, enter the defective corrected request, correct the defect(s) sua sponte, and/or request a submission from the patent owner in order to correct the defect(s). As a specific example, if the defect in the corrected request is limited to the omission of a copy of the patent for which supplemental examination is requested, and the copy of the patent was submitted with the originally-filed request, the Office may exercise its option to sua sponte accept the original submission of the copy of the patent as part of the corrected request.
