French Patent & Trademark Attorney, a regulated profession 

The profession of Intellectual Property Attorney, also called CPI, is regulated by the Intellectual Property Code.
A CPI is an independent professional, a engineer and/or lawyer with a specialised legal degree.

It is mandatory to possess: 
  • A national legal, scientific, technical or equivalent post-graduate degree,
  • A diploma delivered by the International Centre for IP Studies (CEIPI), or a recognised equivalent,
  • Adherence to the prescribed conditions of these diplomas and of professional practice; at least three years professional practice required.
  • Successful completion of a professional aptitude exam or eight years of professional practice under the responsibility of a person qualified in the field of intellectual property.
Subject to also demonstrating good moral characteristics, meeting these conditions entitles the candidate to be added to the list of those qualified in matters of intellectual property. 
Once accepted on this list, qualified persons may then decide to either follow their careers in business or industry, or they may elect to become a CPI, working exclusively for a specialist professional practice.
Persons wishing to pursue this second option must then also register on the official list of CPIs, and it is mandatory that they become members of the CNCPI.
