The Central Reexamination Unit (CRU) plays a crucial role in processing a Reexamination of a Reexamination. According to MPEP 2295 , “When the file for the new reexamination proceeding (reexamination of a reexamination) is first received by the Central Reexamination Unit (CRU), the CRU technical support staff will print out a copy of the issued reexamination certificate and make it of record in the second reexamination file wrapper as a preliminary amendment.” This ensures that the examiner has the most up-to-date version of the patent claims for review. The CRU also completes checklists and reviews the reexamination for compliance with guidelines.
