Check whether your brandname has already been registered
If your name has already been registered by another party, you may become involved in a conflict with the holder (owner). Many start-up entrepreneurs incorrectly assume that a simple check of the Trade Register and a Google search will suffice.
In order to make sure your trademark has not already been registered, however, you must consult the official Trademarks Register. You can search the BOIP's online Trademarks Register free of charge to check whether your name of choice already exists and – if so – by whom it was registered and when.
Please note: A search in the official register is still no guarantee that you will not run into any problems.
