The claiming, on the occasion of a filing made in France, of a right of priority attached to a previous foreign filing entails the obligation to send to the Institut national de la propriété industrielle, within three months of the filing in France, an official copy of the previous filing and, if applicable, proof of the right to claim priority.
If this obligation is not complied with, the claim to the right of priority is declared inadmissible.
The same applies if it is apparent from the documents communicated that the date of the earlier filing precedes the date of filing in France by more than six months or that the reproductions attached at the time of filing in France do not correspond to those of the earlier filing.
