So naming collisions can happen as long as they are in separate domains.
If your brand is too close to another, are you causing confusion?
If you went to the store and saw on the shelf:
- NutriBlend (Parent Co NutriCo)
- NutriActive (Parent Co NutriCo)
- NutriSport (Parent Co Athletic Treats Inc)
Could you think that NutriSport was a product of NutriCo? If so, thats the part the governments care about. They want people to be able to trust in commerce, to maximize tax revenue.
{something}mate is like {something}ly is like {something}r is like {something}io.
They're all just words with a little flourish at the end, who's to say you "own" a word with a flourish? Just seems dumb.
