Description and drawings 

The description and drawings of the parent application and the or each divisional application should in principle be confined to matter which is relevant to the invention claimed in that application. However, amendment of the description should be required only where it is absolutely necessary. Thus, the repetition in a divisional application of matter in the parent application need not be objected to unless it is clearly unrelated to or inconsistent with the invention claimed in the divisional application. As for the matter of cross-references, there is no need for the examiner to check in the description since, under present practice, cross-references are always made between the parent and divisional applications. These appear on the front page of the respective application and patent published after receipt of the divisional application, unless the technical preparations for publication have already been completed.
