In examining the sets of claims referred to above, it will generally be found expedient to deal with each one quite separately, especially where the difference between them is substantial. The communication to the applicant will thus be divided into two or more parts, and the aim will be to have each set of claims, together with the description and drawings, brought into a state where it is in order to proceed to grant.
If the examiner considers that the description and drawings are so inconsistent with either set of claims as to create confusion, he should require the applicant to amend the description and drawings to remedy this. If the applicant voluntarily proposes such amendment the examiner should admit it only if he considers it necessary. In particular, different descriptions and drawings will be required only if it is not possible to set out clearly in a common description which subject-matter is to be protected in the different Contracting States.
Hence this type of application will, after amendment, either consist of two or more distinct sets of claims each supported by the same description and drawings, or two or more sets of claims each supported by different descriptions and drawings.
