As an exception to the provisions of Article L. 613-1, acts prior to the date on which the patent application was made public under Article L. 612-21 or that of the notification to any third party of a certified copy of this application shall not be deemed to have infringed the rights attached to the patent.
However, between the date referred to in the preceding paragraph and that of the publication of the grant of the patent:
1° The patent is enforceable only to the extent that the claims have not been extended after the first of these dates;
2° Where the patent relates to the use of a micro-organism, it is enforceable only from the day on which the micro-organism is made available to the public.
The court hearing an infringement action on the basis of a patent application shall stay the proceedings until the patent is granted.
