Primola is a well known chocolate brand in Romania... just a thought....
Edit: look at primola.ro ... and because it is old, you registered it before the TM (I just guess)... please tell me in PM how much you paid for it... So you have a very big end user.
Thanks Alex- didn't notice that, nice to have a variety of nationalities here in NamePros, always someone who knows something special.
There is no European or US trademark for this name.
