Why do you conduct a trademark clearance search? Because you should know before you invest all the time and money to develop a product or service if your new brand or service is already being called the same thing as you. A simple search of the USPTO trademark database does not necessarily provide you with a full 360 degree view of whether you will have any potential obstacles in obtaining a Federal Trademark Registration.
