question Trademark..

You needn't ask this question here, but to your lawyer. A trademark specialized lawyer.

Otherwise, my own unqualified answer based on experience, yes - due to high similarity, chances are trouble is ahead. But there are a lot of factors, see the advice above.

Why people keep doing this? I just don't understand.

1. No one here can give you legal advice.
2. This question has been asked here 2,457 times: If someone owns YellowBanana and I have BlueBanana will I be in problems? Yes - As long as there are Bananas you are in deep $hit.

All sorted - thanks
