7 year old possible trademark name. Can I sell without legal hassle?

[Sionnach]

Hi Guys,
I have a domain I'm thinking of selling on, I have owned it for over seven years and have never had any contact of any kind from the trademark owners. The thing is the domain is xxxxxx-xxx.com and the two words either side of the - are generic so I'm curious if possibly a)those generic words cannot be trademarked so I'm safe or b)I have owned it for so long some kind of statute of limitations has passed and I am legally entitled to be the owner. If either of these are accurate and I am legally entitled to own and sell this name what would be the best way to sell it? Direct to the owners or sedo etc. The domain is the correct spelling of a major franchise.
Thanks a million in advance,
John.

There's really no way anyone can answer that question with the information you've given.
Seriously, re-read that and pretend you don't know the domain... see?
