In both cases, these 2 word domains are our legal registered company name, one of them having an "s" on the end.
I checked WhoIs a while ago and emailed the party twice who registered the domain and received no response.
They are not using it as a commercial site but for adword traffic.
The domain is a reasonably legit variation of a search term for a type of product that is the same as our company name. We also make this type of product.
What can I do to get the domain back?
