How to file a French Patent application:
Inventions are an essential factor to the economic success of your business. ARGYMA advises clients on technical and legal matters related to patents. We file and prosecute patent applications before the national patent office (INPI).
You would like to patent your invention in France, we take care of your patent application and advise you on the best form of protection to obtain strong rights at a cost effective price depending on the technical field of the invention and best grant opportunities.
The text of your application must be in French for the prosecution, but we may file in another language to obtain an earlier filing date. If the specification is not in French, a French translation must be provided within 2 months after reception of a notification from the French PTO.
If you claim a foreign Priority, it is necessary to provide:
- The official priority document,
- A French translation of the priority documents 1st page (You may provide an English translation of the first page and we translate it into French)
- It is important to know that if you claim a foreign priority, the search report will be available around 15 months after the filing.
