The Central Reexamination Unit (CRU) plays a crucial role in managing the flow of documents and proceedings in the appeal process. MPEP 2676 outlines this role: “All appellant and respondent briefs will be processed by the Board and the reexamination proceeding then forwarded to the Central Reexamination Unit (CRU). The CRU will forward the reexamination proceeding to the examiner after all appellant and respondent briefs have been filed or after the time for filing them has expired.” The CRU ensures that all necessary documents are collected and forwarded to the examiner for review and further action.
