If applicants have taken the opportunity to have other inventions searched, then they may determine that the application is to proceed on the basis of any of these, the other(s) being deleted. If the applicant has not yet done so, the examining division should at the beginning of substantive examination, if it maintains the objection of lack of unity (see C‑III, 3.1.1), invite the applicant to state on which invention the prosecution of the application should be based and to limit the application accordingly by excising those parts belonging to the other inventions. For the latter inventions, the applicant may file divisional applications (see C‑III, 3.2).
