Fees are taken from the tariff of the Bulgarian Patent Office in force since 1 January 2026 and were checked on 16 October 2026. They do not include a representative’s fee. General information, not advice on a specific case.
Since 1 January 2026 the Bulgarian Patent Office (BPO) charges its fees in euro. The tariff is published as a scanned document that cannot be searched by keyword, so we have collected the trade mark fees in one place.
Filing a Bulgarian trade mark
| Step | Trade marks, service marks and joint marks (EUR) | Collective and certification marks (EUR) |
|---|---|---|
| Filing and examination, up to three classes | 265.87 | 516.40 |
| Each additional class | 15.34 | 40.90 |
| Claiming priority (each) | 10.23 | 10.23 |
| Registration certificate | 25.56 | 25.56 |
The basic fee covers up to three classes and stays the same if the application covers only one or two. Each class after the third carries an additional fee. The registration certificate is charged separately and is issued only on express request (Art. 61 of the Bulgarian Law on Trade Marks and Geographical Indications). A registered mark is published in the BPO’s Official Bulletin and entered in the State Register of Trade Marks, both publicly available online (Art. 61 and Art. 7(1) of the same law).
Renewal
A registration is renewed against payment of a fee. The tariff distinguishes two cases:
| Renewal | Up to three classes (EUR) | Each additional class (EUR) |
|---|---|---|
| Before the registration expires | 153.39 | 25.56 |
| Within 6 months after expiry | 230.08 | 40.90 |
For an ordinary (individual) mark in up to three classes, renewal on time costs EUR 153.39 and late renewal EUR 230.08. For collective and certification marks the fees are higher: EUR 306.78 on time and EUR 460.16 after expiry. Each class after the third carries the corresponding additional fee, which also differs depending on whether it is paid before expiry or in the six months afterwards.
Opposition, appeals, invalidation and revocation
| Step | Fee (EUR) |
|---|---|
| Filing an opposition | 178.95 |
| Appeal against a decision terminating the proceedings | 51.13 |
| Appeal against a refusal of registration | 81.81 |
| Appeal against a decision of the Opposition Department | 81.81 |
| Request for invalidation of a registration | 194.29 |
| Request for revocation of a registration | 168.73 |
An opposition against a collective or certification mark costs EUR 357.90. The tariff provides a lower fee of EUR 25.56 for oppositions and invalidation requests based on a court judgment establishing bad-faith filing of the mark.
Invalidation and revocation are different proceedings. Invalidation rests on a defect at the time of registration, while revocation rests on a later loss of the grounds for protection, for example non-use.
Changes and recordals
| Step | Fee (EUR) |
|---|---|
| Change of the owner’s name and/or address | 25.56 |
| Recording a transfer of rights | 30.68 |
| Recording a licence agreement | 30.68 |
| Recording a pledge | 30.68 |
| Recording an interim measure, attachment or inclusion in the insolvency estate | 10.23 |
| Other changes in legal status | 10.23 |
| Recording a partial disclaimer of rights in a mark | 25.56 |
| Extension of a time limit for a reply (first extension) | 10.23 |
| Restoration of a time limit | 51.13 |
| Correction of an obvious factual error in the application | 10.23 |
| Correction of an obvious factual error in the register or the protection document | 30.68 |
| Duplicate of a protection document | 20.45 |
| Search or extract from the register | 5.11 |
How this compares with an EU trade mark
An EU trade mark application at the EUIPO costs EUR 850 for the first class, EUR 50 for the second and EUR 150 for each further class (EUIPO’s official page, read on 16 October 2026). For three classes that is EUR 1,050, and for five classes EUR 1,350.
The comparison covers only the filing fee and the two are not equivalent. A Bulgarian mark protects in Bulgaria only, while an EU trade mark covers all member states. The choice depends on the markets where the client actually trades or will trade.
What these amounts do not include
These are official fees only. They do not include a representative’s fee, a prior search for earlier marks, or the work on any objections from the examiner or on oppositions. The fees for an international registration filed through the BPO are covered in a separate article: “A Bulgarian trade mark as the basis for an international registration”.
