Where two patent applications are filed successively by the same inventor or his successor in title within a period of not more than twelve months, the applicant may request that the second application benefit from the filing date of the first for the elements common to both applications.
The request shall not be admissible where the benefit of the right of priority attached to a previous foreign filing has already been requested for either of the two applications. Nor shall it be admissible where the first application already benefits, by application of the provisions of the first paragraph, from several filing dates, one of which is more than twelve months earlier.
The grant of the patent benefiting from an earlier filing date pursuant to this Article shall terminate the effects attached to the first filing in respect of those same elements.
