  • Substantive examination: Within 42 months from priority date of the invention application and 36 months from priority date of the utility solution, a request for substantive examination must be filed with the NOIP. Otherwise, the application is deemed to be abandoned. The time limit of this examination shall be 12 months counted from the date on which the request for substantive examination is filed or the date of publication of the application whichever come later. If all substantive requirements are met, a notification of intention to grant patent shall be forwarded to the applicant who will have one month to pay registration and publication fees. The patent shall be issued after full payment of fees.
