DPMA or EUIPO: where should a business register its trademark?
The first question is reach. A German trademark at the DPMA protects the sign throughout the Federal Republic. An EU trademark at the EUIPO takes effect as a single unitary right across all 27 member states at once, from one application and under one administration. There is no intermediate tier for a handful of neighbouring countries; there is, however, the route of international registration, on which more below.
What decides the choice is your commercial radius. A business that concentrates its offering on the German market is better off with the national trademark: lower cost, and the same enforceable protection for its core territory. Once a company ships to several EU countries, builds up distribution partners there or sells online across Europe, the calculation shifts in favour of the EU trademark. It costs more, but it covers an entire single market for which separate national filings would, taken together, be considerably more expensive and harder to manage.
The EU trademark also has a downside that should be considered before filing. Its unitary character means that a single conflicting earlier right in a single member state can bring down the whole application. If the sign collides with an earlier mark in a smaller EU country where the applicant is not even active, the opposition still bites for the entire Union.
Where an EU trademark founders on such an obstacle, it can be converted into national applications while keeping its original priority date. That conversion, though, costs extra and delays protection. For a business with a clear but limited foreign footprint, the combination of a German trademark and targeted individual filings in the target countries can therefore be the more robust solution.
