ABSTRACT

A ‘regular national filing’ means a filing which is adequate to establish the date on which the application was filed in that country, whatever may be the subsequent fate of the application.

(4) A subsequent application concerning the same subject as the first convention application, filed in the same convention country, shall be considered the first convention application (of which the filing date is the starting date of the period of priority), if at the time of the subsequent application:

(a) the previous application has been withdrawn, abandoned or refused, without having been laid open to public inspection and without leaving any rights outstanding; and

(b) it has not yet served as a basis for claiming a right of priority.
