Special rules of classification within this subclass

When a document is classified in one of the classes B31B 1/00 to B31B 49/04 it must also classified completely in the groups by allocating the appropriate deep Indexing Codes as provided for in B31B 2201/00 to B31B 2247/00. Classification in B31B 2201/00 to B31B 2247/00 is mandatory.

All aspects disclosed by the documents must be classified ( deep-indexing).

Example illustrating deep-indexing:

This document will be given the following classification:

All relevant information contained in a document must be classified, irrespective its position in the document: description, claims or figures are to be treated with equal importance.
