FYI, a simple trademark search doesn't guarantee that you won't have issues. But is a very good start. Other facts can come into play with something called common law rights (look it up). But as long as you are trying to avoid registering a trademarked name is a step on the right direction. Best bet is to go generic and still there might be issues with that believe it or not. Key is to register first, make good use of the domain and avoid creating confusion in the marketplace. With all that said, you could still get slapped with a UDRP. Yep, the system is broken. Go off to register your domain name. And when you need it get legal advice from an attorney in this field. Those simple rules should help you stay out of trouble.
