If an invitation to pay additional fees was issued during Chapter I and the applicant paid some or all of the required additional fees, and if, where applicable, the objection as to lack of unity was at least partly upheld during a protest procedure, then under Chapter II the applicant will normally be invited (using Form 405) to pay additional preliminary examination fees if all the searched inventions are also to be examined under Chapter II.

GL-PCT F V 10 Lack of unity during search

In many and probably most instances, lack of unity will have been noted at the search stage. In such cases, a search is conducted for the invention first mentioned in the claims and the applicant is invited to pay additional search fees with Form PCT/ISA/206.
