3. Pay the filing and examination fee within 14 days of the Office's notice (late payment within a further 14 days costs double).
4. BPO carries out a formal examination and an examination on absolute grounds for refusal.
5. The application is published in the Official Bulletin of the Patent Office, opening a three-month opposition period.
6. If no opposition is filed or it is rejected, BPO issues a registration decision; the mark is entered in the State Register and the certificate is issued after payment of the certificate fee.
7. Renew the registration every 10 years from the filing date.

## Good to know
- Bulgaria adopted the euro on 1 January 2026; the BPO tariff in force from that date states fees in euro.
- The basic filing and renewal fees cover up to three classes, with a fee for each additional class.
- A separate application may be needed to protect both the Cyrillic and Latin versions of a word mark, as each application covers one sign used as filed.
- The application cannot be amended after filing except to correct the applicant's name or address or obvious errors that do not change the sign or broaden the goods and services.
- Bulgaria is an EU member state, so EU trade marks registered at EUIPO also cover Bulgaria.
