2. Preclassification (for file routing and allocation) 

Applications have to be preclassified to ensure they are allocated to the right search division. The preclassification is assigned using IPC and/or CPC symbols and entered on the electronic file. Based on a cursory read of the application, this initial level of classification is kept as general as possible but should still be specific enough to avoid the need for any further preclassification of the file before it can be properly allocated. In the rare case that this is necessary, arrangements should be made for the file to be redistributed as quickly as possible.
