After a lengthy talk with a firm specializing in these matters he said it would be nearly impossible to protect the common name of discoveryresources as it is not actually trademarked as well as a ton of other reasons. To compose a letter is $750 flat fee including all correspondence there after if I so choose that route. Also I can file locally against them in response to the letter but he does not think that is worth the costs.
So got some decisions to make on using it or switching to my ediscoveryconsultants domain.
