brevet_blem,
"According to the certificate of utility obtain in FRANCE, I am quoted as the first inventor. But two of my bosses are added as 2nd and 3rd inventors without any contribution for their share."
A French Certificate of Utilty is a strange animal. It is a registered patent that is not examined until a dispute arises. It is not itself a utility patent in the normal sense. A certificate of utility is more of a provisional claim to a patent that has to be perfected in order to assert patent rights.
Applicants have to file a regular application for patent within one year to obtain a regular French patent, or to pursue foreign patents with the EPO, US, etc.
I'm not sure what French law says about inventorship, but France is a member of the EPC so it is probably the same.
Article 60 EPC "Right to a European patent" says:
(1) The right to a European patent shall belong to the inventor or his successor in title. If the inventor is an employee the right to the European patent shall be determined in accordance with the law of the State in which the employee is mainly employed; if the State in which the employee is mainly employed cannot be determined, the law to be applied shall be that of the State in which the employer has his place of business to which the employee is attached.
(2) If two or more persons have made an invention independently of each other, the right to the European patent shall belong to the person whose European patent application has the earliest date of filing; however, this provision shall apply only if this first application has been published under Article 93 and shall only have effect in respect of the Contracting States designated in that application as published.
(3) For the purposes of proceedings before the European Patent Office, the applicant shall be deemed to be entitled to exercise the right to the European patent.
So what this says is that fundamentally the right of a patent is given to the inventor(s), but in practice it is the applicant (in most cases the assignee) who is assumed as the owner.
The Applicant only has to make a good faith effort to identify the inventors. The order in which co-inventors are listed has no significance - except for prestige. Not all inventors have to make an equal contribution. Determinative is that anyone that made a material contribution to at least one claim should be listed as a co-inventor.
EPC Implementing Rule 17 Designation of the inventor
(1) The designation of the inventor shall be filed in the request for the grant of a European patent. However, if the applicant is not the inventor or is not the sole inventor, the designation shall be filed in a separate document; the designation must state the family name, given names and full address of the inventor and the statement referred to in Article 81 and shall bear the signature of the applicant or his representative.
If you didn't make an assignment, the applicant might be able to do this without you. This depends on your relationship with the applicant and is a matter of national employment law, and any industrial agreements.
(2) The European Patent Office shall not verify the accuracy of the designation of the inventor.
(3) If the applicant is not the inventor or is not the sole inventor, the European Patent Office shall inform the designated inventor of the data in the document designating him and the further data mentioned in Article 128, paragraph 5.
(4) The applicant and the inventor may invoke neither the omission of the notification under paragraph 3 nor any errors contained therein.
http://www.european-patent-office.org/legal/epc/e/r17.html#R17It is not uncommon that as claims are narrowed in prosecution, one or more co-inventors are properly removed. Rule 19 "Rectification of the designation of an inventor" describes how to correct inventorship:
(1) An incorrect designation of an inventor may not be rectified save upon request, accompanied by the consent of the wrongly designated person and, in the event of such request not being filed by the applicant for or proprietor of the European patent, by the consent of that party. The provisions of Rule 17 shall apply mutatis mutandis.
http://www.european-patent-office.org/legal/epc/e/r19.htmlUnless the co-inventors are willing to agree to remove themselves, you face an uphill battle. Also, until the application is examined and a patent granted on specific claims, it will be difficult to make arguments about inventorship.
Based on the few facts you have presented, it does not appear to me as though this is an "illegal" extension.
It appears as the normal filing within the priority year.
The same co-inventors are listed. That the order is different is meaningless.
Until the patent is granted on specific claims, it is difficult to say who may be removed as a co-inventor.
If you believe there is a substantial amout of money in play, and that you have rights in the invention that have been misappropriated, then by all means visit a French patent attorney, discuss your specific circumstances, and get some proper advice.
