Supplemental Examination Separate from Ex Parte Reexamination
Note:
A supplemental examination is distinct from any ex parte reexamination that may follow, concluding with a certificate and separate from the subsequent reexamination process.

A supplemental examination proceeding is separate and distinct from any ex parte reexamination proceeding that may later result from it. A supplemental examination proceeding concludes with the electronic issuance of a supplemental examination certificate. 35 U.S.C. 257(a) and 37 CFR 1.625(a). Any reexamination resulting from a supplemental examination proceeding will be ordered after the conclusion of the supplemental examination proceeding. See 35 U.S.C. 257(b) and 37 CFR 1.625(b). The ex parte reexamination is a distinct proceeding initiated by its own order. If reexamination is ordered as a result of a supplemental examination proceeding, any papers submitted subsequent to the order should be filed in the resulting reexamination proceeding.

Ex Parte Reexamination Uses Same Control Number As Supplemental Examination
Note:
An ex parte reexamination resulting from a concluded supplemental examination proceeding retains the same control number, even though they are separate proceedings.

Supplemental examination proceedings will be assigned a “series 96” control number, such as, for example, 96/999,999. Any ex parte reexamination resulting from a concluded supplemental examination proceeding will retain the same control number, even though the two proceedings are separate and distinct. After the filing of the request, any correspondence sent to the Office relating to the supplemental examination proceeding or to the resulting ex parte reexamination proceeding should identify the proceeding by the number of the patent, the control number assigned to the proceeding, the art unit, and the name of the examiner.

Correspondence Must Identify Ex Parte Reexamination Proceeding By Patent Number and Control Number
Note:
All correspondence to the Office regarding a supplemental examination proceeding or resulting ex parte reexamination must include the patent number, control number, art unit, and examiner's name.

Supplemental examination proceedings will be assigned a “series 96” control number, such as, for example, 96/999,999. Any ex parte reexamination resulting from a concluded supplemental examination proceeding will retain the same control number, even though the two proceedings are separate and distinct.

Follow-On Papers Required for Reexamination
Note:
Papers filed in response to a Notice of Noncompliant Supplemental Examination Request and any subsequent papers in the resulting reexamination must use the same control number as the concluded supplemental examination proceeding.

It is noted that a corrected request that is filed in response to a Notice of Noncompliant Supplemental Examination Request should be filed as “follow-on” paper(s) in an existing proceeding. Also, even though a concluded supplemental examination proceeding is separate and distinct from the resulting ex parte reexamination, the resulting reexamination retains the same control number as the concluded supplemental examination proceeding to simplify tracking and processing. Therefore, any paper to be submitted in the resulting reexamination proceeding is to be filed as “follow-on” paper(s) using the same control number as was used in the now concluded supplemental examination proceeding.
