Welcome to the new version of the Patents Manual. Please note there are changes to the numbering and sequence of the chapters and pages in the manual. You are encouraged to take the time to explore and familiarise yourself with this new structure. Sub-Codes - Discontinued

Date Published

Sub-codes can collect together documents which relate to distinguishable facets of an IPC sub-group (e.g. a particular chemical compound in a class of compounds, or mechanical devices having a particular feature within a broader IPC sub-group). They can also be applied across groups of the IPC. The IPC Classification Arbiter may be of assistance in selecting suitable sub-codes for sub-coding. The sub-code need not relate to the inventive feature, as this is included in the annotation. In PAMS there is no provision to include sub-codes.

Sub-codes are not in use any more.
