4.2 Basis for the examination 

The basis for the examination is the patent as granted or amended in opposition or limitation proceedings (Rule 90). In cases in which there have already been both opposition and limitation procedures, or more than one limitation procedure, the basis for the examination is the patent as amended in the most recent of those procedures.

The requester may provide information (with the request or later in the procedure) as to why the request is allowable and/or its purpose, but there is no obligation to do so. The purpose underlying the request is of no relevance to the question whether it is allowable.
