Starters:
When you start a company, you choose a tradename. That choice is worthwhile to examine whether you are entitled to use this name. Because it would be a shame if the trade already exists elsewhere in this country and used by a company dealing with the same goods and services.
Registered trademarks are brands / names that are registered under Benelux Convention for Trademarks enjoy protection throughout Benelux. You may be in violation of existing names and protected by trademark laws. It is when you start your business probably prudent to capture (at least) a domain name.
