What is the role of the Central Reexamination Unit (CRU) in supplemental examination?

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.
