No document is required.

We need to know the previous names, legal form and address as last recorded in the French patent register.

According to Article L. 613-9 of the French patent law “To have effect against others, all acts assigning or modifying rights deriving from a patent application or a patent must be entered in a register, known as the National Patent Register, kept by the National Institute of Industrial Property.

However, an act may have effect, prior to entry, against parties who have acquired rights after the date of such act, but who had knowledge of the act when acquiring the rights.”

To record an agreement of assignment, we have to file an application for the registration of this entry, together with :

- copy of the agreement, which must bear the signatures of both parties ; and

- a French translation of the agreement.

Concerning the agreement, we can prepare a formal draft thereof which will be in English and French.

We will receive the registration receipt four or five months after the filing of the request (or about one month if swift processing is requested).
