3.2.2 Additional search fees paid 

If the applicant has taken the opportunity to have other inventions searched, they may decide that the application is to proceed on the basis of one of these inventions and to delete the others. If the applicant has not yet done so and if the examining division maintains the objection of lack of unity (see C‑III, 3.2), it should invite the applicant at the beginning of substantive examination to state which invention the prosecution of the application should be based on 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, 3.3).
