The application procedure, for its processing, must include a descriptive text, a translation of the text into English, German or French if it is in another language and identify the applicant and inventor, in addition to the payment of the official fees for a European patent, which It must be done within 6 months after the publication of the patent. In some very specific cases, some additional documentation is required.
European patents are published 18 months after the filing of the application.
