In December 2019, a client contacted us, with whom we had previously worked on other projects, and hired us to conduct a preliminary trademark search of two trademarks. The services for which the search shall be conducted fall in Class 35 of the Nice Classification of Goods and Services. The preliminary search should be carried out for the territory of the Republic of Bulgaria, as our client wishes to register a national trademark. After conducting the search, it turned out that there is a risk of opposition to be filed against the registration of one of the trademarks since earlier similar marks were found, which is why we recommended to the client to register the mark which does not infringe earlier rights. We prepared an opinion containing an analysis of the results of the search and sent it to the client, with which we completed this project.
