This International Preliminary Examining Authority (i) considers that there are ______________________ (number of) inventions claimed in the international application as indicated in the Annex. (ii) therefore considers that the international application does not comply with the requirement of unity of invention (Rules 13.1, 13.2 and 13.3) for the reasons indicated in the Annex. (iii) recalls that claims relating to inventions in respect of which no international search report has been established need not be the subject of international preliminary examination (Rule 66.1(e)). 2. Consequently the applicant is hereby invited, within the time limit indicated above, to restrict the claims as suggested under item 4, below, or to pay the amount indicated below: ________________________ Fee per additional invention 3. x ___________________________ number of additional inventions = _______________________________ total amount of additional fees/currency The applicant is informed that, according to Rule 68.3(c), the payment of any additional fees may be made under protest, that is, a reasoned statement to the effect that the international application complies with the requirement of unity of invention or that the amount of the required additional fees is excessive, where applicable, subject to the payment of a protest fee. Where the applicant pays additional fees under protest, the applicant is hereby invited, within the time limit indicated above, to pay a protest fee (Rule 68.3(e)) in the amount of _________________ (amount/currency). Where the applicant has not, within the time limit indicated above, paid the required protest fee, the protest will be considered not to have been made and the International Preliminary Examining Authority will so declare. 4. If the applicant opts to restrict the claims, this Authority suggests the restriction possibilities indicated in the Annex, which in its opinion would be in compliance with the requirement of unity of invention. 5. In the absence of any response from the applicant, this Authority will establish the international preliminary examination report on those parts of the international application indicated in the Annex which, in the opinion of this Authority, appear to relate to the main invention.
