Trademark problems with "Dirty Pin" vs "Dirty Pineapple"

I want to buy a domain "Dirty Pineapple" that resembles a trademark "Dirty Pin".

I want to promote a "Dirty Pin" product on "Dirty Pineapple" is this a problem ?

Can the owner stop me from selling his product on my domain because the domain is similar, but different at the same time?

You can probably get away with dirty pineapple, as it is very distinct from dirty pin, but using the actual trademark will probably get you sued.

Any other opinions on this topic?

I will use "Dirty Pineapple" to promote "Dirty Pin" products

If you want to invest your time, money and resources into a questionable domain then expect a short ROI.

If you want to invest your time, money and recourses into a domain without issues then don't pick a domain with the exact same letters in the same order.

Go read the UDRP 3 spoke test for a complaint. Your domain selection will fail those and you'll last as long as there isn't a complaint. Better advice is to select a different domain name.

EMD isn't as powerful as it once was. A few years ago an EMD could outrank a solid site for the same content without much authority. Today that isn't the case. You're going to need to have a solid SEO plan besides just finding a similar domain or you'll not get traffic. You're better off picking nothinglikeoriginaldomain.com and putting your SEO skills to work and not worry about a UDRP or C&D down the road. The risk of what you're purposing far outweighs any benefit.

You are right, using "Dirty Pineapple" to promote "Dirty Pin" is obvious, it is confusing.
I made up another domain where the word Pin was not obvious but it could be used to divert traffic from them.

So I decided to use only Dirty in the domain name because is a comon use word and there are many trademarks that use it.
