37 C.F.R. 1.510 Request for ex parte reexamination.
In order for a request filed under 35 U.S.C. 302 to be accepted, be given a filing date, and be published in the Official Gazette, the request papers must satisfy all the requirements of 37 CFR 1.510(a) and (b). The entire fee required under 37 CFR 1.20(c)(1) for filing a request for reexamination must be paid. If the request was filed under 35 U.S.C. 302 by the patent owner and includes a proposed amendment in accordance with 37 CFR 1.530, excess claims fees under 37 CFR 1.20(c)(3) and (c)(4) may also apply; see MPEP § 2250.03.
Pursuant to 37 CFR 1.20(c)(1), there are different filing fees for a large entity, a small entity and a micro entity, when filing a request for ex parte reexamination under 35 U.S.C. 302. In order for a requester to pay small entity or micro entity fees, a requester must affirmatively state that it is eligible for small entity or micro entity status (respectively). For example, a requester can affirmatively assert small entity status by checking the appropriate box in line 3 on the transmittal form (PTO/SB/57). However, only a patent owner requester can establish micro entity status. A third party requester cannot establish micro entity status, since a third party requester is not provided for in 37 CFR 1.29. See 37 CFR 1.27 and MPEP §§ 509.02 and 509.03 for more information about establishing small entity status. See 37 CFR 1.29 and MPEP § 509.04 et seq. for more information about establishing micro entity status.
If the request for ex parte reexamination under 35 U.S.C. 302 is subsequently denied (see MPEP § 2247 and § 22.8), or vacated (see MPEP § 2227 and § 22.6, subsection I), a refund in accordance with 37 CFR 1.26(c) will be made to the identified requester. If the request for ex parte reexamination under 35 U.S.C. 302 is found to be incomplete and the defect is not cured (see MPEP § 2227), a refund in accordance with 37 CFR 1.26(a) will be made to the identified requester.
If the entire fee for ex parte reexamination is not paid or all the requirements of 37 CFR 1.510(a) and (b) are not satisfied, the request will be considered to be incomplete. See 37 CFR 1.510(c) and (d) and MPEP § 2227.
Where the entire filing fee is not paid after the requester has been given an opportunity to do so, no determination on the request will be made. The request papers will ordinarily be placed in the patent file as a submission under 37 CFR 1.501, if they comply with the requirements of the rule. See MPEP § 2206 for handling of prior art citations or written statements under 37 CFR 1.501.
