The United States is one of the few countries in the world that stills follows common law regarding trademark infringement. Because of that, it is possible for businesses or individuals who have created a unique and profitable trademark to have it legally protected, even if they don't register it with the United States Patent and Trademark Office (USPTO). However, that common law trademark may not always carry the same weight a registered trademark does. The registration process is generally detailed, but not prohibitive, benefitting from the expertise of a trademark lawyer. In addition, should any disputes arise over that trademark, a trademark infringement lawyer can pursue that case and generally cause the infringer to stop their actions and pay damages to the trademark owner. There are tremendous benefits to having a registered trademark and being able to enlist a trademark infringement lawyer when that trademark is infringed upon.
