3. Searched claims did not comply with unity of invention
3.1 Payment of additional search fees without protest
If, in reply to the objection to lack of unity at the search stage, the applicant has paid additional search fees without protest, and the application still lacks unity, the objection indicated on Form 206 and in the WO‑ISA will normally be confirmed, where necessary adapted to the amendments/arguments filed by the applicant.
Form 405 is sent out, requesting additional examination fees only for those inventions which have been searched and which are still present in the claims.
