In July 2019, a client contacted us, with whom we have worked on various trademark law projects over the last two years. The client provided us with two-word marks for which to conduct a preliminary search. Our client intends to produce nutritional supplements that fall into Class 5 of the Nice Classification of Goods and Services and for this purpose wants to register a European Union trade mark which will have an effect on the territory of all EU Member States. After conducting the trademark search, it turned out that there was a risk for both marks of opposition, as we identified several earlier marks that were similar and registered for identical goods in class 5. We prepared a written statement containing the results and analysis of the found results and we provided it to the client, advising him to provide another sign for which we should also conduct a preliminary search. Our client took into account our advice and did not file an application for registration of the marks for which we conducted a preliminary trademark search.
