We have a US based company, with a US trademark. We are interested in International Trademarks. I believe there is no central "international trademark database" and trademarks must be filed by country, correct? Second questions, we had someone who was supposed to file a trademark for us in Bulgaria. I want to check and make sure that they filed the trademark under our company name. I tried the Bulgarian Patent Office website ... but I didn't see anywhere to search their database. I also tried the https://worldwide.espacenet.com/ to search the european patent office, but nothing came up in my search. Alternatively, I tried https://trademark-search.marcaria.com and the trademark came up in the search ... but it didn't provide any information (i.e. who filed it, and what company it's filed under). Where can I search for a filed Bulgarian trademark online?
