Section 2
Right to a Patent or an Inventor’s Certificate
12.—(1) Subject to Article 16 and Article 28(1), the right to a patent or an inventor’s
certificate shall belong to the inventor or his successor in title.
(2) The person who first files an application for a patent or an inventor’s certificate or
who first validly claims priority in respect of an application for a patent or an inventor’s
certificate concerning the same invention shall be considered, subject to Articles 14, 15 and
16, the inventor or his successor in title.
13. Where an invention is the result of collaboration between a number of persons, the
right to the patent or the inventor’s certificate shall belong collectively to those persons or
their successors in title. However, a person who has simply given his assistance in the
execution of the invention without contributing a decisive inventive activity shall not be
considered an inventor or joint inventor.
14. If essential elements of an application for a patent or inventor’s certificate or of a
patent or inventor’s certificate have been taken by the applicant from the results of work or
research by some other person without the consent of that latter person, with respect either to
the borrowing or to the filing of the corresponding application, the person injured by such
unlawful usurpation may institute legal proceedings to obtain transfer to himself of the
application or the patent or the inventor’s certificate.
15.—(1) The true inventor shall have the right to be mentioned as such in the patent or
inventor’s certificate.
(2) The provision under paragraph (1) may not be modified by contract.
