Trademark is a sign that is capable of distinguishing the goods or services of one person from those of other persons and can be represented graphically. Almost anything can be registered as a trademark - words, logos, shapes and colors, or any combination of these elements.

Trademarks are unique business identifier due to their individualism, in a word - they distinguish.

Pursuant to the Bulgarian Law on Trademarks and Geographical Indications, the right to a trademark is acquired by registration as of the filing date of the trademark application filed at the Bulgarian Patent Office. The right to a registered trademark is an exclusive right and its owner is entitled to use it, dispose it (assignment or licensing of trademark) and prevent any unauthorized use by others in the course of trade.

Trademark protection can be acquired for all member states of the European Union through a European Union trademark registration (EUTM registration). Its considerable advantage is the territorial protection which extends to the entire territory of the European Union, using a single, fast and cost-effective procedure, subject to uniform requirements for trademark registration and also using a single administrative institution – the European Union Intellectual Property Office (EUIPO). Conversion of European Union trademark into Bulgarian trademark application is possible if it is duly filed in Bulgarian language at the Bulgarian Patent Office.

The validity of trademark registration is 10 years from the filing date of the trademark application and the protection term can be renewed indefinitely for further periods оf 10 years.
