116. If, for purposes of national processing, the applicant intends to make an indication under Rule 49bis.1(a) or (b) of the wish that the international application be treated, in any designated State, as an application for a patent of addition, certificate of addition, inventor’s certificate of addition or utility certificate of addition under Rule 49bis.1(c) (Rule 4.11(a)(i)), or the applicant intends to make an indication under Rule 49bis.1(d) of the wish that the international application be treated, as an application for a continuation or a continuation-in-part of an earlier application (Rule 4.11(a)(ii)), the request shall so indicate under item 2 or 3 in the supplemental box and shall, as the case may be, identify the application in respect of which the earlier search was made or otherwise identify the search, or indicate the relevant parent application or parent patent or other parent grant. The inclusion in the request of such an indication shall, with respect to the international phase, only serve the purpose of international search and has no effect on the all inclusive designation for every kind of protection available under Rule 4.9(a).
