As one of the objects of industrial property of increasing importance in recent years, trademarks are a preferred tool for influencing consumer attitudes and increasing the recognition of companies. However, research in the field of the structure of trademark activity and the dynamics of its change under the influence of various environmental factors remains out of the focus of researchers in Bulgaria. The main purpose of this article is to present the state and dynamics of Bulgarian and foreign trademark activity in Bulgaria for the period 2010-2023. The Bulgarian trademark activity abroad is also measured. The study is based on information on the number of filed and registered trademarks obtained from the database of the World Intellectual Property Organization (WIPO). As a result of the study, it was found that in the period 2010-2023 there was a decreasing foreign activity in Bulgaria, but the interest of Bulgarian applicants and trademark owners in the protection of trademark rights abroad is growing.
