This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Corrections to incomplete ex parte reexamination requests filed under 35 U.S.C. 302 are processed by the Central Reexamination Unit (CRU). The MPEP states:

“All processing of submissions to cure an incomplete request for ex parte reexamination filed under 35 U.S.C. 302 (see MPEP § 2227) is carried out by the Central Reexamination Unit (CRU).”

This means that the CRU handles all aspects of processing these corrections, ensuring a centralized and efficient approach to managing incomplete reexamination requests.
