In the sixties, there was a company called Acme Widgets. They disappeared in the early 70s. In 2003, the domain name acmewidgets.com was set to expire and I grabbed it. In 2005, a new company (unrelated to the original) was started called Acme Widgets Group. They purchased acmewidgetsgroup.com. I think they own a trademark on "Acme Widgets Group". Since I bought the acmewidgets.com domain 2 years before this company was started, am I clear of any trademark dispute? OR, could they file a claim with ICANN? I am NOT using the domain for anything other than directing it to a page that provides a link to the domain's for sale page at TDNAM.com.

Thanks in advance!
