Unless the application is directly ready for grant, communications under are issued by the Examining Division and notified to the applicant or the appointed representative. In such communications, the Examining Division invites the applicant to reply within a given period, by correcting the "deficiencies noted and the description, claims and drawings", where appropriate. If amendments are filed, the amendments must not extend the content of the application as filed, or, in other words, there must not be any added subject-matter. In that context, the applicant is master of its own application in that the decision to amend or not, and how to amend the application, is a decision of the applicant alone (although the Examining Division may apply pressure to have amendments made).
