upon entry into the European phase the EPO as designated Office will consider whether the application, which in the meantime may have been amended by the applicant, meets the requirement of unity of invention. If not, the examining division will invite the applicant to restrict the application to one single invention. Where not all inventions contained in the application were searched by the EPO because of non-payment of an additional search fee, the applicant must restrict the application to one of the inventions covered by the ISR (or the SISR, see point 294). Since an unsearched invention may only be pursued in the European phase by filing a divisional application a decision on non-payment of additional search fees in the international phase is to be well considered (see point 648). However, as of 1 November 2014 it will be possible for the applicant to
pay, within a period of two months, one or more further search fees in respect of any unsearched inventions claimed upon entry into the European phase in order for these to be covered by a further search (see points 653 ff).
