6. Plurality of inventions and further search fees

If the search division or the ISA raises an objection of lack of unity, a further search fee is payable under R. 64(1) EPC (R. 46(1) EPC 1973) or Art. 17(3)(a) PCT, respectively, for each invention involved. If the fee is paid in due time applicants may select the single invention or group of inventions which they wish to retain in the main application.
