Where the patent application results from the conversion of a utility certificate application in accordance with the provisions of the second paragraph of Article L. 612-15, the search report fee must be paid within one month of the date of receipt of the conversion request.

The request to convert the patent application referred to in Article R. 612-3 in an application for a utility certificate shall be made in writing at any time during the eighteen-month period from filing or from the priority date if priority has been claimed and, in any event, before the start of the technical preparations, provided for in Article R. 612-39, undertaken with a view to publication of the patent…

The period during which third parties may submit observations expires three months after the publication provided for in Article R. 612-62. Under penalty of inadmissibility, observations from third parties are submitted, in duplicate, under the conditions provided for in Article R. 612-57 and shall be accompanied by the documents cited or a reproduction thereof and all necessary information or evidence. This latter provision does not apply to patents; however, at…
