Copyright
A logo is protected by copyright if – in short – it is original. This protection is created automatically and therefore no registration is required.
The requirement of originality is met if the logo is not taken from another logo and if enough creative choices have been made.
If someone else (largely) takes over the logo, there may be an infringement.
Whether your logo will be protected and whether it has been infringed is not an exact science. We, therefore, recommend that you have a specialist advise you about the protection and the infringement.
