Once you have a product or service and think you have a name for it, how do you know you can use it as your own? What happens if you unintentionally use a registered trademark name? In the United States, under what common law, people can lay claim to a mark if they use it. It is not necessary to formally register a trademark. This fact and the sovereignty states have over the creation of chartered business entities and trade names, makes a trademark search imperative before one spends time and money registered a trademark.     

Too many people use a name without knowing if they have legal coverage, and they put up big marketing campaigns with names that later they find they cannot use. Performing a Comprehensive Search Study before you decide to register your brand mark is a wise decision especially when you consider future risks of litigation. 

It is a good idea to conduct a Study before you start doing business with a trademark.  It may not be in your best interest to use a mark if another company is already actively conducting business in the same class.  That company may be able to object to your use of the trademark and prohibit you from using the mark in a court of law.
