I own a domain name that has part of a term a company has trademark. I researched it and saw them lose court cases against other people due to it becoming a genericized trademark. They do not own the exact trade mark of the domain i own, it's blank right now, and it could easily be used for something non related since their word is very basic. I was contacted by them dropping hints of trademark threats and wanted to purchase it but they did not have an attorney contact me. I told them they can email an offer and they sent a weak slap in the face offer. My question is what would it cost them if they wanted to pursue it? I don't mind selling it to them but I would definitely want to get what I have into it and not hand it over for peanuts. I paid low-mid 4 figures for the domain.
