Patents are governed by Part VI of the French Intellectual Property Code (Articles L. 611-1 et seq. and R. 611-1 et seq.), the European Patent Convention (also referred to as the Munich Convention) and EU regulations Nos. 1257/2012 and 1260/2012 of December 17, 2012 regarding the unitary patent (not yet effective; they will only apply from the date of entry into force of the UPC Agreement).
The "first to file" system is defeated in case of fraud and mitigated in case of prior personal possession.
The law No. 2019-486 of May 22, 2019, known as the PACTE law, is an important reform of French patent law. It strengthens the examination procedure, modifies the limitation periods, extends the duration of utility certificates and allows their transformation into patent applications. It also introduces the possibility for 3rd parties to oppose French patents whose grants have been published as of April 1, 2020, before the National Institute of Industrial Property (INPI).
Regulations (EU) No. 1257/2012 and No. 1260/2012 of 17 December 2012, which implement enhanced cooperation in the creation of unitary patent protection, set up the European Unitary Patent System. These regulations entered into force on January 20, 2013 [vl1] [LC2] and are applicable from June 1, 2023 which is the date of entry into force of the Agreement on a Unified Patent Jurisdiction establishing the Unified Patent Court (UPC).
To date, 17 Member States have ratified the UPC Agreement (including the 3 Member States with the highest number of European patents in force in 2012: Germany, France and Italy). It is expected that further Member States will ratify the UPC Agreement in the coming year.
The unitary patent system makes it possible to receive patent protection in up to 24 EU Member States by submitting a single application with the European Patent Office, thus simplifying the procedure and making it more affordable for applicants.
The Unified Patent Court (UPC) is an international court established by the participating EU Member States to deal with infringement and validity cases of unitary patents as well as European patents, thus eliminating costly parallel proceedings and increasing legal certainty. The unified patent jurisdiction consists of a first-level court in Paris (with a section in Munich) and a court of appeal in Luxembourg, as well as local divisions in several countries. For instance, Paris, hosts a local division.
Then, from June 1, 2023, and for a transitional period of at least 7 years, national courts will continue to have concurrent jurisdiction for "classic" European patents and supplementary protection certificates.
The UPC have exclusive jurisdiction to rule on the validity and infringement of patents with unitary effect.
