3.4 Verification of the IPC classification 

As a general rule, applications will not be systematically scrutinised after leaving the search division in order to verify the correctness of the IPC classification assigned by the search division. The Office may, however, institute such sampling check procedures as are deemed necessary to ensure correctness and uniformity in the application of the IPC. It is, of course, for the line managers to arrange for such checks as they consider necessary, having regard to the experience of their members, before the applications leave their units.
