I have recently bought an 11 year old domain name. The domain in question was used by a business for that time period before they ended their business sometime in late 2016. Meanwhile another company had a trademark in place for one of their products calling it the same word as the domain since 2015. Their main website and company goes by another name. My domain name is simply the name of one of their products. The trademark is for a singular product but the domain name can apply to many other things. It was being used by the prior owner in the business area that I myself see it would be the most desirable. I have this domain listed as a "may be for sale" only because I am not sure what applies here and what doesn't to protect myself. Since the trademark came after the domain and legitimate other business and the domain was and can be used for a different type of business or product entirely can I sell it?
