Recommended Answer:
No, and it's COPYRIGHT.
You trademark a slogan, you don't copyright it. See a good trademark lawyer.

• Your business name is only protected in the county where you register your DBA - at least in the sense that nobody else can register their biz under the same name. If you want to register a trademark (if your trade name can be trademarked), you need to hire an Intellectual Property attorney. You can register a trademark for around $1200 or so. Until registration is completed, you use the "TM" sig. Note that not all names can be trademarked, and the trademark, if granted, only applies to the category in which your name is registered.
  
  Your "slogan" - you mean a service mark? This can be registered, but you can also protect it to some extent by using the superscript "SM" after the slogan. That way you can spend the money to register it after it has been in use and gains some recognition.
  
  Names and service marks cannot be copyrighted. Some may meet requirements and be trademarked or service marked.
