Article 156

The European Patent Office as an elected Office

The European Patent Office shall act as an elected Office within the meaning of Article 2(xiv) of the Cooperation Treaty if the applicant has elected any of the designated States referred to in Article 153, paragraph 1, or Article 149, paragraph 2, for which Chapter II of that Treaty has become binding.
