The Central Reexamination Unit (CRU) plays a crucial role in the supplemental examination process: The CRU is responsible for determining whether the request for supplemental examination is complete. It reviews the request to ensure compliance with 37 CFR 1.610. The CRU assigns a filing date to compliant requests. For incomplete requests, the CRU issues notices detailing the defects and providing an opportunity for completion. MPEP 2812 specifies: “The Central Reexamination Unit (CRU) will determine if the request is complete.” This initial processing by the CRU is a critical step in ensuring that supplemental examination requests meet all necessary requirements before proceeding to examination.
